Definitions
- Dryers that use catalytic lamps as a heat source are enjoying increasing popularity.
- This for good Reason On the one hand is the primary energy used, namely the combustion gas (natural gas, propane, butane or liquid gas), very inexpensive compared to electrical energy.
- To the another can be one with such catalytic emitters Infrared radiation especially in that long-wave Create an area that is used for drying or firing coatings, especially paint finishes particularly, effectively is. Energy savings are also achieved by that essentially only the one to be dried Coating, but not other objects heated become.
- the long-wave radiation from a catalytic emitter the property by a compared with short or medium-wave rays moderate energy density the subject Warm and dry gently.
- Impurities contained in this supply air thus remained unoxidized, so that the removed from the dryer Exhaust air from a separate exhaust air cleaning device, for example a thermal, a regenerative or a catalytic afterburning device had to be fed.
- a separate exhaust air cleaning device for example a thermal, a regenerative or a catalytic afterburning device had to be fed.
- These devices then served often as collective disposal for everyone with organic Substances, especially exhaust air volume flows loaded with solvents, those in the entire facility, so not only in the dryer.
- the object of the present invention is a dryer of the type mentioned in such a way that on a separate exhaust gas cleaning device is dispensed with can be or at least the amount of exhaust air can be reduced so that the separate exhaust gas purification device kept smaller and therefore cheaper can be.
- the idea of the invention is as follows: if catalytic emitters are used that do not require air cooling, can put the entire in the drying room of the dryer Supply air via the connection of the catalytic lamp for forced air to be directed, so that all supply air that enters the drying room at least once on the catalytically active layer flowed past or through the catalytically active layer is. In this way it becomes possible to use the catalytic oxidative conversion of organic impurities to be carried out in the supply air as a controlled reaction, including quantitative predictions of reaction sales possible are.
- the supply air supplied to the dryer can partially from the dryer itself, but also from other parts of the system originate, so that the dryer as a "collective disposal facility" So far for the entire system provided separate exhaust air cleaning devices can replace in whole or in part.
- the catalytic emitter can have a connection via which is only supplied with air.
- This Supply air is placed in one place within the catalytic heater directed from which it is a surface of the catalytic flow to the active layer. This will Conditions created under which a controlled Implementation of the organic contained in the supply air Contamination takes place.
- a fan For convective heating of the objects to be dried a fan can be provided with which the air in the Drying room can be circulated.
- an embodiment of the invention can be achieved in which the dryer is multi-stage is formed, with each stage in the in one of the Claims 1 to 4 described manner is formed and the connection for exhaust air from the upstream Stage with the connection for the supply air each downstream stage is connected.
- the dryer is multi-stage is formed, with each stage in the in one of the Claims 1 to 4 described manner is formed and the connection for exhaust air from the upstream Stage with the connection for the supply air each downstream stage is connected.
- the object of the present invention is also a Method for operating a dryer at the beginning Specify the type in which the in the dryer contained catalytic emitters in a targeted and controllable manner used to clean the supply air supplied to the dryer can be.
- the total dryer provided with the reference number 1 comprises a dryer Housing 2 with an outer wall 2a and an inner wall 2 B.
- the inner wall 2b of the housing 2 encloses one Drying room 3 by a device 4, z. Legs Partition, in two air-technical separated Sub-rooms 3a and 3b is divided.
- Freshly painted Vehicle bodies are not shown in the drawing shown locks, coming from the left, into the sub-area 3a by means of a likewise not shown Conveyor system introduced by this through a the device 4 provided lock in the subspace 3b transferred and leave the housing 2 of the dryer 1 by another not shown in the drawing Lock.
- each catalytic emitter 5 includes 5 an outer housing 6 and an inner housing 7, between which a flow gap serving as air guidance 8 remains.
- the outer case 6 and the inner case 7 are on the lower in Figure 2, the drying room in operation 3 facing side open.
- the inner housing 7 of the catalytic emitter 5 contains from top down a gas distribution device 9, in which a gas supply line 10 opens, an insulation layer 11, an electrical preheater 12 and one catalytically active layer 13, which on the in Figure 2 downward-facing side is exposed.
- the entire catalytic emitter 5 is by the choice of materials used designed to withstand high temperatures, therefore also required at operating temperatures of for example 250 to 300 ° C no cooling air.
- Air supply connector 14 of the catalytic radiator 5 connected are supplied with supply air.
- This supply air can z.
- the contained in the sub-room 3a of the drying room 3 Air can be drawn through a line 16 in which a blower 17 lies, circulate. Branches from line 16 a further line 18 leading to the air supply nozzle 14 in the second sub-room 3b of the drying room 3 arranged catalytic radiator 5 leads. That too Sub-space 3b is assigned a circulation line 19, in which is another blower 20. From the circulation line 19 leads an exhaust duct 21 to the outside atmosphere.
- the dryer 1 described above works as follows:
- the catalytically active layers 13 of the different catalytic rays 5 with the help the electrical preheaters 12 to a temperature preheated from approx. 150 to 200 ° C, for catalytic Oxidation of the combustion gas is required.
- the catalytic emitters 5 in both sub-rooms 3a, 3b of the drying room 3 via the respective gas supply lines 10 combustion gas supplied. This is in the corresponding catalytic emitter 5 by the gas distribution device 9 over the entire flow cross-section evened out, penetrates the insulating layer 11, which also because of their flow resistance a contribution to the equalization of the gas flow performs, and then reaches the preheated catalytic active layer 13.
- FIG Dryer 1 The airways are shown in detail in FIG Dryer 1 as follows:
- the air in sub-room 3a is blown with the help of the blower 17 circulated and an air stream drawn off via line 18, the - converted to the same temperature - that Air volume corresponds to that through the line 15 is supplied.
- the air circulated by the fan also overflows the object to be dried and heats it convectively.
- the amount of circulated air also determines whose temperature is the amount of energy transferred.
- the catalytic emitters 5 transfer to the one to be dried Subject energy in the form of infrared radiation. This Amount of energy is by the amount of combustion gas that is supplied through the lines 10, and through the Distance between the object to be dried and the Catalytic radiators 5 determined.
- a second type is shown as the Catalytic radiator 5 can be supplied with supply air.
- the catalytic emitter 5 of FIG. 3 coincides with that of Figure 2 are identical.
- Via the gas supply line 10, however, does not become a pure combustion gas, but a mixture of polluted supply air and combustion gas inside the catalytic emitter 5 initiated.
- This mixture is in a premixer 23 produced, the combustion gas via a first line 24 and via a second line 25 containing pollutants Exhaust air is supplied.
- the lines are installed in the dryer 1 of FIG. 1 25 the premixer 23 the catalytic emitter 5, the assigned to the left subspace 3a of the drying room 3 are parallel to the branch lines 15a, 15b to the Line 15 connected, through which the contaminated supply air comes from the evaporation zone while the ducts 25, which is the right in FIG. 1 subspace 3b of the drying room 3 are assigned, parallel to the lines 18a, 18b leading to the already pre-cleaned air Line 18 are connected.
- the ratio in which the combustion gas 24 in the premixers 23 is mixed with air set that according to the pollution of the Air catalytic oxidation as complete as possible the pollutants take place. In a corresponding way the proportion of the polluted air via line 25 to the premixer and what proportion over the air supply nozzle 14 is supplied to the catalytic emitter 5.
