Each of the controllable units and the structural training as a whole can be enclosed by a housing and, depending on the end use and the building materials used, with structural steel in I or H profiles or angles be reinforced, as shown at 3, and supported above ground with the aid of supports 4. Every single unit has, neighboring a pair of their parallel sides, opposing metallic flow lines, generally with

In the case where a plurality of units are arranged side by side and forms a unitary embodiment, conventional line connectors 7 are provided, the one Allow flow communication between adjacent inlet and outlet conduits. In addition, with a system with four controllable units according to FIG. 1, the outlet line

Every chimney duct or furnace shaft has a grate or a floor made of drawn metal 11 ″ which is a stationary one Heat exchange bed 12 of material particles carries, e.g. Pieces of ceramic material, steel or other material with a sufficiently high melting point, good heat transfer properties » so good and good durability. Any channel or Shaft sticks out through the loose or bottom 11 from expanded Metal with a Varbimdungsleitung 19 in ¥ ®rbindurag, the a flow connection between the lines 5 and 6 and the respective channels or shafts guaranteed. Accordingly, each box-like envelope has a plurality of channels or shafts in common connection bit of an upper chamber 13, which is a StrönrangsTerbück between the channels or shafts above the tops of the partitions, as well as a single connection between the inlet and outlet pipes 5 and 6 via connecting pipes 19 »which run below the Scheider.

The inlet lines 5 are via a. a total of bit 14 designated pipeline network with an Albgas stream from one of numerous types of industrial plants such as Iroekaer, 0J? em ₉ shaft furnace, fume cupboards, etc. in ¥ ert »imäuiig. The exhaust gas flow from an industrial plant is old with the help of a Bniek-Zug-Cretolase through the pipeline system 14, because the atomic gas flow enters the fieiiaigiangsanlage through the first inlet pipe 15, to the blower chamber 16 and then chireli <ti @ second inlet pipe 17 through it for manufacturing the power to the Sinla @ leituBg @ u 5 äex

splits. After the elimination of a significant percentage of the impurities contained in la stream, it occurs into the outlet line 6 and is moved from there through the exhaust gas line 20, the exhaust fan chamber 21 and the exhaust gas chaoht 72 therethrough.

In the following the details are given, which concern the gas flow from the inlet conduit 5 through the beds consisting of material particles and into the outlet conduit 6.

Each firing channel or shaft 10 is assigned a connecting line 19, which is in the inlet and outlet lines 5 and 6 ends. Each line 6 has a time-controlled actuator at its two ends in lines 5 and 6, which is equipped with flow regulators such as the closing member 22 which is articulated via arms 23 to a horizontally extending articulated shaft 24 in such a way that it from a horizontal position where it closes the associated end of the line 19 to an almost vertical position is movable where it opens the end. A mock driver 25 has an arm that extends downwards under the lock extends at an angle of approximately 30 ° to the horizontal, set with respect to its corresponding closing member 22 and it can be pivoted on the shaft 24 *. Timed actuation occurs when each driver moves accordingly a squat 26 mounted on a shaft 27 rotated by an unillustrated motor. Each of the six connecting line ends within each line and 6 is accordingly equipped with a closing element, a lock driver and locks, so that a corresponding Pre-determined opening of the 4 connection line ends realized can be. The relationship of opening is given by the angular

109808/1379

relationship of the cam 26 about the axis of the shaft 27 "is determined in such a way that the following © open by replacing angled ¥ the crouch 26 around the shaft aeb.se at equal angular intervals can be realized "

As has been established, a central, ■ upper grass or oil burner 8 ensures a higher degree of efficiency of the combustion, corresponding to the opening of the respective connecting line ends within the inlet and outlet lines 5 and 6 one after the other approximately sinusoidally, so that each inlet flow on the inlet side at the inlet chamber 13 at the central burner flows past before stepping out to the Auelaßleitung.

For the purpose of special consideration of the flow, the closing members 22 are in the cut-out part of the pig. 1 designated as 22a-l with entsprechendea Kstmzeiohmmgen for manholes, pipes, B © tt © a c _o, "The ITbgee = · stream from an industrial plant such as ^ ₀ B ₀ © IAEM froclmer is first advised within OCE © lufmateieleitung 15 received and then gets through fii © & ebläg © kaiui © r 16 Matareli and up through the second reception line 17 Mniurcli in you distribution line 18, which divides © flea Str © a to i © a EialaSleitraigen 5. When the shaft 27 rotates for the purposes of a sequence, the cut-away part of FIG. 1 being considered, the closing organ 22a is opened in the connection duct 19a when the lock 26 moves along i © s Hitnetaers 25a and it and the aaa organ 22a , eit äem © s la firm connection is 9 raises, so ia @ see <ä @ s Orgaa 22® is located in the off east position «, An d © r Ä« slü, Bl © ituagss®ite t-yi ^ fi read the following open ier closing organs old reference with Orgüii® mn i @ r Bial © S ~ line side staggered tosmrti, äaß iss Safelioios'gmii 22g & ®v connection line 19a Si © S © 3älleist © llraig ® ± nnlwmt ₉ woam

-the organ 22a is in the open position. This is necessary for the operation of the plant because otherwise a stream would only flow from the inlet line to the outlet line without flowing through the heat exchange beds. The sequence of operation of the closing elements in the outlet line is such that when the closing element 22a is in the open position, the closing element 22j assumes the open position. Accordingly, the flow from the inlet line 5 enters the connecting line 19a at its end opened by means of the member 22a and, because the other end of the connecting line 19a is closed by means of the member 22g, moves through the expanded metal base 11a of the firing channel or Shaft 10a up through the bed 12a of material particles at elevated temperatures and into the chamber 13, where it is heated by means of the oil or gas burner 8. The current is then driven down the shaft 10d with the help of the push-pull blower system into its bed 12d of material particles, through this bed and the base 11d made of expanded metal into the connecting line 19d and from there into the outlet line 6. The flow naturally chooses the channel or shaft 10d because the closing member 22j, which is assigned to the shaft 10d only on the outlet side, is open, while the other closing members on the outlet side are essentially closed. It can be seen from this that the gas flow from the inlet line, which moves up the shaft 10a and down the shaft 10d, must come into contact with the flame of the gas or oil burner 8 in the chamber 13. This desired correlation between current and flame is brought about with the help of the joint opening of the solenoids 22b and 22k, 22o and 221, 22d and 22g, 22e and 22h and 22f and 221, the opening of the organs on each side, inlet or outlet, In Sequence proceeds, where

moreover, the flow in each case into the chamber 13 is adjacent the flame of the burner 8 arrives and thereby heat again receives.

It should be noted here, although explained in more detail below, that the gas flow at the inlet side of the units is of relatively low temperature and when it passes upward through a bed of material particles "at an elevated temperature to chamber 13", it is heat exchange experiences with the bed and through this heated wirä ^, whereby the temperature of the bed "that it flows through is reduced. to play the temperature of the bed like at AEEN desired, higher value for spontaneous combustion or oxidation to bring @ r Terumroinigungen, is the Current that flows downwards through the bed and reaches the outlet duct, heated to an elevated temperature in chamber 13 when it passes the flame of the burner, so that a reverse heat exchange takes place with the bed, which it passes through when flowing downwards , the bed being brought back to the desired higher temperatures, for example when the closing element 22a is open, the relatively low temperature flow to chamber 13 passes through bed 12a, which is at higher temperatures, and cools it. However, this is SehlieJfergaB. 22g open and the current flows out of the chamber 13 »after it? has been heated by means of the burner 8, down through the bed 12a, when it is driven to the outlet duct, so we are

It is safer important to keep the gases in chamber 13 for possible FIuB to drive to Auelaßleitung 6 to thereby increase the efficiency of the combustion, albeit at the expense of thermal effect, over the cleaning of the beds Realize, each of the connecting lines 19 has adjacent its end in the inlet line 5, a downwardly extending tube 30, which a connection between the inner and the outer roughness. The ends of the downwardly extending tubes 30 close in a plane below one Angle to the vertical according to FIG. 3 from such a way that in the normal case the at the upper end of the tube 30 at the end of the tube hinged closing cap 31 by gravity and / or under the influence of the current holds the tube 30 open to the training air. As stated earlier, each connecting line has 19 open ends dominated by closing members 22 in both the inlet and outlet lines 5 and 6, respectively opening the ends with the help of the loekenbetetrieb. So that the exhaust gas flow of an industrial plant passes through the unit or units 1, both should Ends of each connecting line 19t ** previously described, never be open to the same tent, as such a condition would allow the gas flow from the inlet duct moved through the connecting line to the outlet line without penetrating the beds of material particles. However, with respect to the ends of each connection line, three conditions can exist and still permit continuous operation of the system: both ends can with Help the organs 22 be closed. Either end can be open while the other is closed. Tuck three Conditions are now with respect to a trunk 19 and its tube 30 on the inlet side examined more closely.

and become the inlet line 5 with a flow velocity of approximately 110 mVmin. (3900 ofm.) After it has passed through the blower chamber 16. The beds of material particles are first heated by means of the (Jas or oil burner 8 in order to achieve an average temperature gradient of about 0.56 ° C / 2.54 om (33 ° P per inch), the working range of which starts from a lower temperature the base, consisting of expanded metal, reaches a temperature τοη approximately 871 ⁰ C (1600 ° P) at the chamber 13. Once steady operation has been achieved, the burner only needs to add enough heat (between etohs up to twelve million BTU per hour) In order to cover insulation, radiation and conduction losses as well as severe thermal performance deficiencies during combustion or heat exchange. Accordingly, the contaminant components of the exhaust gas flow from the dryer are ignited, that is, their autoignition temperature ranks in different levels of the bed, with a certain amount depending on the oxidation properties of the components Ignition also occurs in chamber 13 «As the inlet flow decreases to about 110 ⁰ C (230 ° P), the bed of material particles is cooled from approximately one meter in the shaft receiving the inlet gas stream as the stream passes through the bed to chamber 13. Since the characteristic bed temperature for the particular exhaust gas stream from the dryer is required for proper combustion or incineration of the contaminant components in the stream, the packed bed must be brought back to the correct temperature for it to operate effectively. As stated earlier, this is accomplished by successively opening the inlet and outlet closing members 22 in such a way that the flow between the inlet and outlet lines sweeps past the oil or gas burner in the chamber 13.

the latter condition is heated, the gas stream in chamber 13 to approximately 871 ⁰ C (1600 ° P) so that the bed is returned in the downward movement by a previously chilled bed heat energy, and the desired temperatures • be restored. Because of the Wäraeaustausohes in the restoration of the elevated temperatures for the bed of the exhaust air can escape at a temperature between 149 ⁰ C and 260 ⁰ C (300 and 500 ° F). In order to prevent leakage of unburned gases to the outside and hot spots in the casing, it is generally preferable to keep the static pressure in the chamber 13 somewhat below ambient pressure and to regulate the output of the exhaust fan for this purpose. The latter can be achieved with the aid of a pressure sensor within the outlet line 6, which senses pressure changes in this and signals the change in pressure to the blower unit of the chamber 13, while if the pressure falls in the exhaust duct, the output of the exhaust fan is automatically reduced.

Vaoh essential work result of the air purification system can solid bodies, which are not carried by the exhaust gas route from an industrial plant, on the upstream sides of the beds are trapped close to the ground, increasing the resistance to the current and reducing the incineration performance thanks to the partial decomposition and impact of the existing current. To set the flow resistance to normal Decreasing values becomes an "outbreak" of the plant initiated. This phase can be any single bed of material particles of any unit or an entire unit of a concern uniform, e.g. standardized form of execution »

in any case, the current continues to flow through the rest of the system. The "burnout" phase is realized by the complete or partial closing of the inlet and outlet flaps 51 and 53 of the connecting line 19, which is assigned to the bed that is to be "burned out", see Fig. Tuck flaps can accordingly by hand can be controlled automatically by control buttons 50 and 52 or using common rule principles, in accordance with a time function, bed characteristic or the like. If a line 19 or all lines 19 of a unit of a multi-unit system are closed against flow by means of the flaps 51 and 53, then - even if the closing elements 22 in the inlet and outlet lines should be open - the flare bed of material particles is appropriately adjusted high temperature rise! st, namely through constant absorption of thermal energy through radiation, convection and conduction from the oil or gas burner without subsequent hindrance from movement of the cooler inlet stream. Are the high temperatures, usually zwisohen 427 and 649 ⁰ C (800 ⁰ F 1200 ⁰ F) reaches over the ganse bed depth, the captured in the upstream portion of the bed solids warden carbonized or gaseous products "burnt out". To remove the carbonized or "burned out" gaseous constituents, a siphon line 54 can be installed, which connects the respective lines 19 and the inlet line 5 to one another. There is a FIuS for the life circuit line 54, which is controlled manually or automatically according to conventional principles by means of a flap 55, which allows a desired flow of the carbonized constituents back through the entire system, as they were received in the 4 inlet line 5.

Like in Pig. 1 inclined by dashed lines, a life leakage line 40 can be installed in the system in order to allow return of the gas flow from the outlet line 6 and inlet line 5 for the purpose of return through the system. Such a U level outlet line can be regulated manually and / or automatically with the help of conventional means such as flaps in the line in such a way that the outlet flow, in particular the combustion loosening, is reduced at predetermined intervals Is abnormal or low flow conditions prevailing, can be recycled for improved results.
