Description

DESCRIPTION

Saturated or superheated steam or hot air generation system

Technical Scope

[0001] The invention relates to a system that is generally used in the textile field and that is integrated into steaming machines, allowing the dyeing material of printed or plain-dyed fabrics dyed with various dyes to be fixed on the fabric in such a way that it cannot be removed again.

[0002] In particular, the invention relates to a system that allows maintaining dyed fabrics in a saturated steam condition or in a superheated steam condition or in a hot air condition for a certain period of time, which is capable of creating each of these three phases.

State of the art

[0003] Nowadays, various machines are used in many areas, mainly in the textile sector, in order to expose products to steaming air or hot air and to the drying process. These machines generally consist of a main body where the process takes place and external steam or hot oil boilers where the heat is supplied. The disadvantages of existing systems are described below.

a) Steam boiler rooms are difficult to install and operate.

b) It is a source of serious danger because it is a pressurized container.

c) Although steam is partially needed in the plant, all boiler rooms are operating and all conveyor lines remain hot, causing serious energy losses.

d) Due to the long conveyor lines, energy losses, pressure drops, water hammer, valve failures (condensate, pressure reducer, control valve failures, etc.) are inevitable.

e) The temperature is limited based on the maximum working pressure of the installed boiler. (Pressure/Temperature of saturated steam)

[0004] Utility model No. CN202644178 entitled "Digital Continuous Steam Ager" which received protection in China is a machine of the above type and is used for the heat treatment of fabrics. The invention receives the steam it needs from an external source through a set of pipes. Therefore, the installation costs are very high and it takes up too much space. In addition, due to the need to establish a connection between the machine and the steam source, time is lost and labor costs increase. In addition, energy is lost as well.

[0005] Another patent is European Patent No. EP2195575B1, entitled "Overheated Steam Generator". Said invention includes a straight tube segment (1), an electric resistor (3) wound on said straight tube segment and powered by an electric source, a wound tube segment (2), one end of which is connected to said straight tube segment, which is wound to form a cylindrical spiral covering said electric resistor. However, when the details of the invention are examined, it is seen that it is a completely different method.

[0006] Furthermore, Patent Application No. TR2014/05976 owned by the present applicant refers to a steaming, heating and drying machine comprising all the elements used in areas where the products require steaming, hot air and drying processes and comprising a main body that houses and preserves all the elements and a process chamber located inside said main body and in which the products are treated, characterized in that it also comprises a heat source that provides heat and a heat transfer cell in which said heat source is located and which can be filled with water to generate steam when necessary.

[0007] US2012137990A1 relates generally to liquid vaporizers and specifically to systems and methods for liquid vaporizers and operating liquid vaporizers. Heat from the vaporizer may be provided by an in-line heater, such as an electric heater with a heating element that heats air, which is initially at room temperature, as it flows through the electric heater and into the vessel. The heated air then heats the polyethylene rings and the liquid, resulting in vaporization of the liquid.

[0008] US2016308364A1 relates to a steam supply and heat preservation atomizing device comprising a heat preservation boiler, a high heat capacity material, a heater, a supply pipe, a liquid source and a steam outlet. The high heat capacity material comprises nitrate, such as sodium nitrate, potassium nitrate, lithium nitrate or sodium nitrite, which are too dangerous because they are all flammable chemicals.

[0009] EP1862733A1 relates to a fast steam generator comprising a porous body which is heated by a hot fluid flowing through the porous body in a direction perpendicular to the penetration direction of a medium to be vaporized. At least a portion of the medium to be vaporized is atomized by spraying onto the inlet surface of the porous body. The body is made of a porous ceramic material. The medium to be vaporized is water or a non-explosive liquid. The hot fluid is an exhaust gas from an internal combustion engine or a heating system with a temperature higher than 1200 [degrees] at the point of entry into the interior of the porous body.

[0010] US8814953B1 relates to a system and method for dyeing fabrics, including a dye spraying station, a dye fixing station downstream of the dye spraying station, and at least one rinsing station downstream of the dye fixing station. The process includes opening the fabric with a spreader to keep the fabric flat and taut, spraying the outer surfaces of the fabric with a dye, and exposing the fabric to atmospheric vapor to chemically react and fix the dye to the fabric.

[0011] WO0148296A1 relates to a low pressure steam jet fabric finishing machine (10) for steam fixing dyes to fabrics during a steaming cycle, having a substantially cuboid housing (12) defining a water tank (70) with a heating element (72) and a cylindrical steaming chamber (88). Steam from the heated water rises to a steaming core (80) having an inlet (84) in fluid communication with the water tank (70) and subsequently to the steaming chamber (88) through a plurality of holes in the steaming core (80). The dyed fabric is wound on a helical spring (90) which is inserted over the steaming core (80) and positioned in the steaming chamber (88) for dye fixing during a steaming cycle.

[0012] In said invention, water in the water-filled heat transfer cell was heated to produce steam and the resulting steam was used in the process. The most important difference compared to the present invention is: In the present invention, a non-water-filled structure is used. The most important difference of the method according to the invention is not to heat the water, but to wash the dry air and saturate it by spraying the water onto the hot surfaces.

[0013] When examining the previous applications, it is clear that this is not a similar invention that eliminates the technical problems mentioned.

Objective of the Invention

[0014] The invention is defined by a system according to claim 1 and a method according to claim 2. The main object of the invention is to develop a system in the textile field, which is integrated into steaming machines allowing the dyeing material of printed or plain-dyed fabrics dyed with the various dyes to be fixed on the fabric in such a way that it cannot be removed again.

[0015] Another main object of the invention is to develop a generator that allows maintaining dyed fabrics in the conditions of saturated steam, superheated steam or hot air for a certain period of time, which is capable of creating each of these three phases.

[0016] Another main object of the invention is to enable dry air to be washed and saturated by spraying water onto heated surfaces not filled with water.

[0017] Another object of the invention is to condition the air with the heating battery and to wash and saturate the dried air by spraying water on various hot surfaces.

[0018] Another object of the invention is to direct the washed and conditioned air back to the system through the fans.

Detailed Description of the Invention

[0021] The invention relates to a system which is generally used in the textile field and is integrated into steaming machines (chambers) which allow the dyeing material of printed or plain-dyed fabrics dyed with the various dyes to be fixed on the fabric so that it cannot be removed again, which allows the dyed fabrics to be kept in the conditions of saturated steam, superheated steam or hot air for a certain period of time, and which is capable of creating each of these three phases.

[0022] Figure 1 shows a general schematic drawing of the generator according to the invention. As shown in the Figure, the fabric (B) moves on the suspension bars to remain for a desired time in the chamber (A). Figure 1 shows the entry point (1) of the ambient air to the system and the entry point (2) of the conditioned air from the system to the environment.

[0023] When the system calls for saturated steam air, the return waste air, which is taken through the ambient air inlet point into the system by the circulation fan (F) and contaminated by the low temperature gases resulting from the fixation reaction, is washed by the pressurized water through the water conditioning system (D) and sprayed by the nozzles and sent to the heating battery (C).

[0024] The return air washed with the water sprayed through the nozzles (E), and simultaneously humidified again, is meanwhile heated to about 3 - 6°C above the saturated steam temperature (100°C) in the gas or fluid fuel heating cell by the heating battery (C) or by the pre-heated superheated oil battery located in the region of the heating battery (C) and passes through the separator (G) and is brought to the homogenized condition after increasing its pressure and is sent to the chamber (A) through the ambient air inlet point into the system (1).

[0025] When superheated steam air is desired, the outlet temperature is adjusted to the desired temperature (110 - 250°C) while the process and system are the same as described above.

[0026] When the hot air is needed or partial fresh air inlet is required, the fresh air inlet (H) is opened by adjusting the heating coil (C) to the desired hot air temperature without operating the water conditioning system (D) (pressurization, level, flow, water supply and drainage system) while the process and system are the same as described above. Thus, dry hot air is sent to the chamber (A), the suspended fabric (B) is dried, the return air is reheated, partially renewed and the residual ambient air is removed by the chimney fan (K).

[0027] A system has been developed that allows dyed fabrics to be kept in saturated steam, superheated steam or dry hot air for certain periods of time, capable of creating each of these three phases.

[0028] By means of the system according to the invention, it is ensured that the dry hot air is washed and saturated by spraying with water the hot surfaces that are not filled with water, the air is conditioned by the heating battery, the dry air is washed and saturated by spraying with water various hot surfaces, the washed and conditioned air is redirected to the system through the fans.

[0029] All these processes are carried out by the system integrated in the chamber according to the invention, the energy, the production costs are significantly reduced, the need for the systems such as external steam boiler, hot oil boiler, etc. has been eliminated. Furthermore, the systems such as steam boiler and fluid transport facilities between chambers are eliminated.
