This rapid cooling step is generally referred to as "quenching (hence the occasionally the device of the present invention is also referred to as the cooling cell of the present invention). At time A, the hot gas is usually combined with a relatively large amount of refrigerant (which may also be condensed by the actual product). The composition is contacted to thereby partially or completely condense. The condensate product has a high degree of rot property in many cases. The contact of the material of the stationary dry gas cooling bath usually does not pose a problem. The wet weather of the knot and the contact with the material of the cooling pool can cause corrosion problems. In that area, it is especially necessary to avoid temperatures above about 110 ° C, otherwise condensation will occur. As for the low pressure only The process is usually solved by a cooling bath made of corrosion-resistant materials, such as ceramics, plastic materials, or graphite. For example, a cooling tank made entirely of graphite is in the manual "KOLONNEN, DIE REIHENWEISE" of SGL ACOTEC GmbH The PERFEKT GEBAUT SIND” is described on page 26, which can be accessed from the website http;//www.sglcarbon>cQm/gs/prodser/process/pdf/pe 201 d. 5 200815088 (2006 5 14) This cooling bath made of graphite is only allowed for ultra-low pressure. However, if it is required to quench with higher pressure, it requires a permitting material. However, such materials (for example, alloy steel or Special materials) In some cases, there is no long-term anti-corrosive rice, or it is too expensive to be considered economical. Therefore, the object of the present invention is to provide a device for cooling pressurized hot gas. (Cooling tank) which causes the gas to partially or completely condense and form a highly corrosive condensed product (as needed together with the surrounding refrigerant). ^ ίο [Summary of the Invention] Achieving this goal is by providing a use a device for cooling hot gas (cooling tank) having a pressure-resistant wall and at least/corrosion-resistant gas-conducting inner tube. It is possible to protect the wall by using a combination of a pressure-resistant wall and a corrosion-resistant gas-conducting inner tube (its Most of the pressure-resistant but not corrosion-resistant ones are protected from the condensed phase, thereby reducing the corrosion effect. As a result, it is possible to operate the cooling pool on the one hand and the cheaper on the other hand. The material as a pressure resistant material, such as a steel alloy conventionally used in boiler and appliance constructions. 0 The hot gas within the scope of the invention means, in particular, a gas having a temperature generally between 100 2 Torr and 2000 Torr, at a temperature of no to The range of l〇〇〇〇c is the best for the car.

They can also be thermal industrial waste gases produced by chemical synthesis processes, for example, 6 200815088 Deacon process, etc. Exhaust gas. The hydrazine is oxidized to form chlorine and, depending on the inlet temperature, is cooled with a hot gas of 5 10 15 to, for example, 1 G (^c (possibly to make the upper enthalpy). Lower (temperature at the outlet of the cooling cell) The invention relates to a cooling device comprising a financial wall and at least a corrosion-resistant device (a cooling pool for cooling the hot gas for a preferred installation 1 The pressure vessel, the at least one inlet port, the condensed pool area and the head area/product are used for the whistling liquid circuit, and the circuit is exchanged and recirculated through the heat exchange two H gas f a head region, wherein the contact region comprises a zone in which the condensate is introduced into the contact pipe to bring the condensate into contact with the hot gas from the corrosion resistant V.

The gas in the range of (: is the use of the present invention, characterized in that the hot gas is co-currently or in parallel with the gas guide (or several air pipes) of the device and by Cooling the hot gas with the cold I. "Contact 15 1000 bar. The preferred feature of the method is that the pressure in the gas/liquid contact zone is up to 20 in the process. The gas system containing hydrogen chloride is hydrogen chloride. The evolved gas produced by the oxidation of the oxygen phase, wherein the gas is cooled in the region of the gas pipe until the hydrochloric acid and the water condensate. The gas I has a pressure-resistant wall in the device of the present invention. The pressure of 1000 bar is more than 5 bar. τ, the pressure of excess pressure, the excess pressure of 6 bar or more, the excess pressure of 1 bar or more is better. The pressure resistance of the device For the sake of comparison, the material selected from the group of materials is preferably made of a conventional steel alloy for the structure of the lower core, and the pressure-resistant wall can also be composed of a conventional one. Nickel, molybdenum is used as a 200815088 Alloying materials and materials such as New Zealand and its alloys Precious metals such as the beginning and / silk, can be further increased by two = conventional materials can also be lined with plastic 'such as 'especially gas-containing polymer materials, such as the group of * special", or lining the metal of the present invention The device has at least a "airway tube" for the inner tube of the corrosion-resistant gas guide, or "a plurality of air-conducting tubes, which are all used for one-seven s々τ, and the moon-shaped wood is used to receive the hot gas. In-e) enters the cooling pool), _ has pressure resistance, and ^ g gas. As a result, this has been particularly able to avoid most of the heat: the pressure is often not the same as the rot (four) consumption. The air ducts of the device of the present invention are generally arranged in a vertical direction. The straight-to-back type of corrosion-resistant air-conducting inner tube is preferably made of the following materials: graphite and its variants, ceramics (for example, carbon crucible), quartz glass, plastic (for example, fluoropolymer) , examples of PVDF, HALAR types, etc.). ^ The eclipse is usually made of materials that are not pressure-resistant, that is, especially 疋 = withstand excess pressure of 0.5 bar or more, or excess pressure above.疋, Ί 〇 置. The device of the present invention allows for the incorporation of inexpensive materials to form a pressure-resistant and corrosion-resistant device, "this, and generally has the same pressure-resistant inlet nozzle. The mouth must be resistant to, but not necessarily made of, a material that is particularly resistant to corrosion, as the dry, hot gases have not yet condensed. The gas will only be corrosive if it is condensed at 20 200815088, especially if the moist aqueous phase is in contact with materials, especially metals, at high temperatures. If necessary, the inlet nozzle can be heated to prevent the incoming gas from condensing in this area. In a particular embodiment operating in a cocurrent mode, it is advantageous for the inlet nozzle of the apparatus of the present invention to be positioned above the inner tubes of the corrosion resistant gas and 5 not to contact the circulating cooling liquid, thereby avoiding the inlet nozzles. Rotten money. The apparatus of the present invention preferably has a member capable of preventing the pressure-resistant wall from coming into contact with high temperature (especially above 110^:) condensation. This is usually the case in a humid environment where the device has a relatively high temperature (especially above 110 °C) (for example, the area between the inlet nozzle 3 and the pressure wall 5 in Fig. 3). . In the preferred apparatus of the present invention, the members for preventing the parts which are easily corroded by the apparatus from coming into contact with each other (especially the condensed phase of the pressure-resistant wall and the high temperature (especially above 110 QC)) are at the pressure-resistant wall and the intake port. There are 15 feed pipes for the seal gas or inert gas in the area between them. The sealing gas prevents the incoming hot gas from coming into contact with the readily corrodible component in the condensed phase. A preferred embodiment of the components of the cooling cell of the present invention for operation in a cocurrent manner is shown in Figure 3. As can be seen from Fig. 3, an additional flow guiding device (e.g., inner cone 7) can be added to prevent hot gas 20 from coming into contact with the wall of the cooling liquid zone. Another preferred embodiment of the components of the cooling cell of the present invention for use in a cocurrent mode is illustrated in Figure 1. A preferred sealing gas for the apparatus of the present invention may be, for example, an inert gas (e.g., nitrogen) or a noble gas. In the industrial waste gas of the Dickon method, oxygen is a post-sealing gas of the preferred 11 200815088, which has been abundantly present in the jade exhaust gas. In a preferred embodiment of the invention, the corrosion-resistant airways are at least partially, and the cold portion is surrounded by the body. It is preferred that the cooling liquid enters the gas guide at the upper portion of the airway. The cooled liquid exits the lower end of the air tubes after cooling and is circulated or fed back into the device. The apparatus of the present invention is generally fabricated wherein at least a portion (generally a major portion) of the pressure resistant wall is in contact with the circulating cooling liquid. As a result, it is possible to effectively prevent the pressure-resistant wall (usually it is not resistant to corrosion or slightly resistant to corrosion) in that area because the areas usually do not reach the temperature required for it. Preferably, the present invention is configured to have a circulating cold liquid between the pressure resistant wall and the air conduit. The circulating cooling liquid enters at the upper end of the air conduit and is collected at the bottom and is recyclable. In the apparatus of the invention, or in the process of the invention, in particular the cooling liquid used is water or an aclueous acid such as dilute hydrochloric acid. 15 Other process-specific washing agents (for example, alcohols or aqueous amine solutions) are also possible. In a particular embodiment of the apparatus such as that illustrated in Figure 3, the incoming hot gas system is directed in parallel with the cooling liquid. In the cocurrent flow operation, the air duct nozzle of the device additionally has an upper nozzle for sprinkling cooling liquid. In another embodiment, as shown in Fig. 1, the incoming hot gas is guided in a manner countercurrent to the coolant. The present invention is generally suitable for use in hot gases having a cooling temperature in the range of 100 to 2000 ° C, and a heat gas in the range of 110 to 1000 ° C is preferred (measured at the inlet vent). The apparatus of the present invention is generally constructed to be suitable for operations in which the excess pressure is in the range of from 0 to 1000 bar, and the excess pressure is preferably in the range of from 6 to 1000 bar. The invention further relates to a method of cooling a hot gas using the apparatus described above. It is preferred that the excess pressure is carried out in the range of 6 to 1000 bar. Further, the temperature of the incoming gas is preferably in the range of 110 to 10 °C. In order to illustrate the invention, the drawings illustrate the presently preferred embodiments. However, it is to be understood that the invention is not to be limited [Embodiment] 15 Fig. 1 is a schematic view showing a specific device of the present invention, which operates to flow a liquid and a gas to be quenched in a countercurrent manner. According to the present invention, for example, it can be used for cooling to partially or completely condense. And there is hot gas generated by the corrosive thermal condensation product. Those skilled in the art will appreciate that, in the broader context, the scope of the patent application of the present invention may also incorporate or incorporate the individual features disclosed herein. The hot gas stream 1 enters the lower portion of the quenching apparatus 2. After cooling and condensation, the cold gas stream 3 exits at the top. In the middle portion of the cooling bath 2, the gas stream is directed through a plurality of tubes 4. These pipes are all located in liquid 5 (water or acid is preferred) and liquid 5 contains the condensed product after the inclusion of 13 200815088. The bottom end of the pipe 4 is fixed to the pipe P 2 Pe W) 20. The upper end of the duct 4 allows the liquid 5 to pass freely by means of a support grid 24. The pump 8 used in the middle part is cooled by the cooling tank 2 via the circulation pipe 7 , the ancient package office 1 , the factory body 6 and the liquid 5 〇 liquid gripping the teeth over the flange 5 at the bottom end of the pipe 4 Liquid 9. The heat exchanger 1 is used to cool the circulation 7 and the liquid 2 is in the middle portion. The liquid 5 flows into the pipe 4 at the upper end of the pipe 4 and flows downward in the 5 以 in a manner countercurrent to the flow of the upper pure body. 10 15 20 4 5 is evenly distributed on the line, generally the right side of the pipe can be ~2 as shown in Figure 2 'for example with a tooth 1 but: other types of liquid distribution, for example Axial or A-cut: S into the slot at the upper end. Then 'use the liquid flowing down the second production: 盥 = and make it partially or completely condensed. Therefore, it is necessary to prevent the hot coagulation, the production and the cooling pool 2 from being contacted by the rot (four) portion. The coagulated product 2 - for example, hot hydrochloric acid. For example, at the intake port 12 or the cooling wall 13 or the official seat 2G, it is necessary to prevent corrosion. For example, in the case of the intake port 12, it is possible to take a series of treatments, first of all, to prevent the ingress gas from condensing on the nozzle 12 by heating. ^ 1 illustrates a double-layered outer casing 14 (for example) that is not used for this purpose, and the double-layered outer casing 14 provides a heat medium, such as steam or hot water or heat transfer oil, via a nozzle 15. The heat medium can exit again via the nozzle 16. This heating can also be used, for example, , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Another measure that must prevent the condensed product dripping from the pipe 4 from wetting the nozzle 12 is that, first of all, the pipes 4 must be clearly separated from the nozzle 12. 14 200815088 5 15 20 The second way to achieve this is that the pipes 4 do not fill the entire cross section of the cooling pool a but only part of it. The size of this portion is such that the anti-frusting plate (printing out gUard) 17 can be placed between the nozzle 12 and the pipes 4. The slab-face is exposed to the reduced body and the other side is exposed to the condensed product. Therefore, it is impossible to rule out the possibility that the condensed product is heated and the temperature causes the anti-sanding board to be rotted. Since the tamper plate is not formed to face the body, it does not need to be resistant to impurities. Therefore, it can be stabilized by a hot liquid that does not have pressure resistance but is sturdy (for example, 'hot hydrochloric acid'), such as 'appropriate material for post-fossil or nitrite or other suitable ^^ ^ or plastic. In order to avoid rot (4) hot condensing products, the wall is filled, and the middle part of a mH2 (where the pipes 4 are arranged) is the U product. Unlike the thermal coagulation product ::r=r, a suitable metal of the pressure-resistant metal wall = U' can be used, but the gas in that area is formed by the heat-condensed product. There are no more risks in the lower part of the cooling pool 2 (below the pipes 4). Various measures are taken to prevent the corrosion of the wall 13. First, the hot gas from the gas discharge port 12 reaches the wall. For this purpose: the guide is from, through the cylindrical duct 18. The pipes 18 are leaked from the hot condensate products of the pipes under the pipes, and are made of a material having stability of the rotted liquid. Since the pipe ΐδ has rotted heat (Ρ bear bearing), the material and the pressure plate are applied to prevent the hot gas from flowing under the pipe 18 and reach the wall. The same way f8 15 200815088 is erected in the pool body liquid 6 Carrying ring 19 on it. In order to prevent hot gas from flowing between the pipe 18 and the pipe fixing seat 20 and reaching the wall 13, the spring structure 21 is used to press the pipe 18 against the pipe fixing seat 20. Since this compression does not result in a complete seal, and since the nozzle 13 is inserted through the pipe 18, further measures can be taken to prevent the hot condensed product from being corroded in the lower wall 13 shape. For this purpose, the sealing gas 23 is passed through the mouth f2 into the space between the lower wall 13 and the duct 18. The dense two is a gas of h, such as nitrogen or argon, but the application of air or carbon dioxide: the nature of the gas is determined by the use of a suitable sealing gas core for the use of a cooling pool for the oxidation of hydrochloric acid (Dickon method) Another special gas is oxidized to ruthenium because the gas is used in the process to make the sealing gas of hydrochloric acid: 匕 does not constitute a foreign component. Between 15 and 20 flows between it to prevent part of the gas flow 1 in the pipe 18, the gamma body 13 gas 23 can only pass through the ^I mouth 12. The gas flow can be prevented because the seal passes through the nozzle 12 at 2() Ή 18 1 '. Since it must flow into the inside of the cooling pool with a gap between the 18 openings, i flows backward through the two gaps' which prevents entry into the gas pipe holder 2f> Ζυ There are also a series of measures to prevent corrosive:, minus ° ° ° cold condensate on the surface of the camping seat 20 ☆ & same # can; ^ 卩 the pipe mount. Although the hot gas can condense on the other side, as a result of cooling the dry gutter mount, a cold film of the condensed product is formed, which is a corrosive hot liquid condensed thereon. The membrane has a protective effect. 16 200815088 Other measures can be taken to improve the cooling of the pipe mount. For example, the pipe fixing seat may comprise a copper core having particularly good thermal conductivity, and therefore, in particular, may be on the cold side of the pipe fixing seat (on which there is a cold condensed product), a warm surface (the gas is condensed thereon) A small temperature difference is generated between). 5 As for another measure, the pipe holder itself can be cooled. For this purpose, for example, it can be made of two sheets, and a groove-like passage can be added to one side of the first sheet. Then, the second sheet is placed on the side of the first sheet to which the passage has been added. When the two sheets are joined together in a suitable manner (e.g., upper screws), the tube mount has a cooling agent ίο a passage through which the flow can flow. Moreover, the pipes 4 are not inserted in close fitting with the pipe fixing seat 20 but slightly protruded from the pipe fixing seat. As a result, the hot gas is not directed to the pipe at the pipe mount and is at a distance from the pipe mount. The advantage is that the hot gas and pipe fittings do not come into direct contact at the pipe joining 15 places. In addition, the intersection of the conduits 4 through the conduit holder 20 is protected by a liquid film to protect the gas from high temperatures. The pipe 4 itself is exposed to the corrosive attack of the thermally condensed product. However, as with the splash guard 17 and the duct 18, since they do not need to have pressure bearing properties, the materials of manufacture can be the same as those of the components. 2A is a schematic view of a device for cooling according to the present invention, which partially or completely condenses hot gas, wherein the gas to be cooled and condensed is guided in parallel with the cooling liquid. . It will be apparent to those skilled in the art that, in the broader context, the scope of the present invention may also be incorporated or combined with the individual features disclosed herein. 17 200815088 In particular, you can cool and condense the gas shown in the above figure and below, which is described in more detail below, and its hot condensation products (such as 'aqueous hydrochloric acid') One (four) mouth 3 enters the upper portion of the quenching device 2 with a gas that is still hot in the plug-in duct. From there, the assembly does not have to have a corrosion-resistant inner tube 4 that is resistant to θ, which is connected to the device. Since this and the temperature-resistant plastic are only 2 dimensional and only have dimensional stability, the ceramic material is the same as the appropriate material/material. The inner diameter of the insert pipe 3 and the inner pipe 4 is the same as that of the inner pipe 4 = the insert pipe 3 is usually smaller than the diameter (up to the same size). In the difficult inner tube 4 6, the magic (1) coffee generation also touches the jacket. There is a cooling liquid between the five. The eight straw is continuously circulated by the pump. The upper tube is overflowed and the inner tube 4 is formed on the inner surface of the inner tube 4, and the rotation can be used to protect the corrosion-resistant material of the inner 4 from excessively high temperature, and on the other hand, the cold table can be used for cooling and condensing heat. gas. Therefore, the vertical spacing between the inserting gas supply 3 and the corrosion resistant inner tube 4 must be large enough so that the liquid can flow smoothly on the upper edge of the inner tube, even under different operating conditions. For this purpose, the upper edge of the inner tube 4 facilitates the addition of teeth, as shown in Fig. 3g. In addition, it is necessary to avoid contact of the overflowing cooling liquid 6 with the hot-plugging tube 3, since this causes a spoil in the area where the plug-in duct 3 is affected. In order to further prevent the hot earth gas from flowing through the gap between the plug-in duct 3 and the inner tube 4 in the pressure-resistant sheath 5 of the device, the dry sealing gas 8 is transported in a constant manner into the space above the gap, whereby An air cushion of 2008 18 200815088 is formed and the (10) 7 pairs of _= inner tubes 4 made of the heat-resistant storage stock to be cooled are forced. Also installed by function. A suitable sealing gas 8 ^, oxygen can provide an advantageous flow of 5 10 15 20 pieces. However, in principle, the pounds generally depend on the overall process of the strip or carbon dioxide seems to be particularly "nitrogen or argon" and air in the case of the possibility of using oxygen as a chemical method (Dickon method) of the oxidation of special acid gas into chlorine Already for Ί 8, because oxygen is making the salt component.

In the area where the intake pipe connected to the mouth of the nozzle is passed through the inner taste 4, the seal is not required to be completely resistant. The gas that has been cooled at that time then flows into the lower half of the quenching unit together with the cooling liquid or condensed product, which is used to separate the gas phase from the liquid phase. The gas or condensation product and the pressure-resistant outer wall 5 of the device are in contact for the first time. However, since the gas and the condensed product have been cooled in the inner tube 4, it is possible to use a material having a corrosion-resistant temperature significantly lower than that of the hot gas. _ The unspinned but cooled gas 11 exits the device via the air outlet 12. The means for directing the gas stream 13 (e.g., the deflector) ensures that there are as few spin-off products or coolants as the gas stream exits. The cell body of device 14 collects the liquid separated by the cold gas and is removed by pump 15. First, a portion of the liquid as a coolant is delivered, via a circulation line, to the heat exchanger 17, where it is cooled to a fixed temperature level, and finally provided as a coolant, again to the spray nozzle and at a pressure resistant The set is 5 and the inner tube 4 overflows. A suitable control device ensures that the amount of coolant in the system _ remains approximately the same. Remove excess liquid and condensed product as a condensed product16.
