Description of the Related Art Since the exhaust gas of a coating booth contains an organic solvent that causes environmental pollution, it must be passed through a direct combustion or catalytic combustion deodorizing device before it is released into the atmosphere. Although the organic solvent component is combusted and decomposed, the catalytic combustion type deodorizing device uses an expensive catalyst, which increases the facility cost and the fuel cost of the burner that heats the catalyst to a predetermined reaction temperature. The direct combustion type deodorizing device has a drawback that the fuel cost is further increased as compared with the catalytic combustion type because the large amount of exhaust gas is directly heated by the flame of the burner. In addition, since the concentration of the organic solvent contained in the exhaust gas of the coating booth is extremely low, a considerably high temperature is required to burn and decompose the organic solvent, resulting in a huge fuel cost.

を防止している(特開昭63−88076号)。For this reason, recently, the organic solvent contained in the exhaust gas is once collected by a rotor-type solvent recovery machine, and the collected organic solvent is removed from the rotor-type solvent recovery machine by hot air and concentrated. Means for feeding to the above deodorizing device is used. Further, the present applicant uses an activated carbon deodorizing device that adsorbs and removes organic solvent components in the exhaust with an activated carbon layer as an alternative to the above deodorizing device, and this deodorizing device is included in the exhaust gas of a coating booth. Since the moisture adheres to the surface of the activated carbon layer and loses its adsorption function in a short period of time, the moisture in the exhaust is removed in advance by a rotor type dehumidifier to prevent the function of the activated carbon deodorizing device from deteriorating. 63-88076).

スを更に低減することを技術的課題としている。However, the rotor-type solvent recovery machine for increasing the solvent concentration in the exhaust gas and the rotor-type dehumidifier for removing the water content in the exhaust gas have a honeycomb structure drum having a large number of vent holes. Since it is a large-scale device that rotates the rotor with a motor, it requires a considerably large installation space and its equipment cost is still high. Therefore, it is a technical object of the present invention to further reduce the equipment cost, running cost, and installation space without lowering the processing capacity of the exhaust gas processing device.

る。According to the present invention, while one folding screen filter advances into the exhaust passage to adsorb the organic solvent contained in the exhaust gas, it exits from the exhaust passage and enters the filter regeneration chamber. The other folding screen filter housed is regenerated by wiping off the organic solvent component and water adsorbed on the surface by the high heat of the hot air sent into the filter regenerating chamber. Then, when the folding screen filter advancing to the exhaust passage adsorbs a certain amount or more of the organic solvent contained in the exhaust gas and the moisture that inhibits the adsorption of the organic solvent, the folding screen filter is withdrawn from the exhaust passage. At the same time as the filter is housed in the filter regeneration chamber, the regenerated folding screen filter previously housed in the filter regeneration chamber is advanced to the exhaust passage instead of the filter. As a result, since the folding screen filter having a good adsorption efficiency of the organic solvent can be always interposed in the exhaust passage, the organic solvent contained in the exhaust can be reliably removed.

はない。Further, the hot air for wiping the organic solvent component from the surface of the folding screen filter needs to be fed into the filter regenerating chamber for a certain time only when the folding screen filter is housed in the regenerating chamber. Fuel costs required to generate hot air are low. Furthermore, since the amount of hot air sent from the filter regeneration chamber to the solvent removal device is significantly smaller than the amount of exhaust gas discharged from the painting booth, etc., it can be used as a solvent removal device to remove the organic solvent contained in the hot air. For example, even when a direct combustion type or catalytic combustion type deodorizing device is used, a small deodorizing device is sufficient and the equipment cost and fuel cost are significantly reduced. Further, since hot air is sent to the solvent removing device, even when an activated carbon deodorizing device is used as the solvent removing device, there is a possibility that a problem such as a decrease in the efficiency of removing the organic solvent due to moisture adhering to the activated carbon layer may occur. Absent.

態に再生される。However, either the right or left folding screen filter 2R (or 2L) across the exhaust flow path 1 advances into the flow path 1 so as to close the exhaust flow path 1, and the exhaust gas of the coating booth is exhausted. While the organic solvent contained in the filter plate 4 is being adsorbed by the activated carbon layer 5 of the filter plate 4, the other folding screen filter 2L (or 2R) that has exited from the exhaust passage 1 is stored in a folded state. Hot air of about 120 ° C. is sent into the chamber 9 of the chamber 3L (or 3R) from the hot air generator 10 through the hot air supply pipe 12 for a certain period of time, and the high heat of the hot air causes the surface of the folding filter 2L (or 2R) to flow. Not only the adsorbed organic solvent component but also water that hinders the adsorption of the organic solvent component is wiped off by evaporation, and the entire filter 2L (or 2R) is regenerated to have the best adsorption efficiency.

Therefore, the equipment cost and fuel cost can be very low. In addition, since hot air is sent to the solvent removing device 14, even when an activated carbon deodorizing device or a zeolite deodorizing device is used as the device, moisture adheres to the activated carbon layer or the zeolite layer and the removal efficiency of the organic solvent is reduced. That's not it. Therefore, since it is not necessary to provide an expensive and large-scale rotor dehumidifier, the equipment cost, running cost, installation space, etc. of the entire exhaust treatment device can be significantly reduced.

If the filter entrance / exit 8 is shielded by an opening / closing door or a partition curtain, the organic solvent and water adsorbed on the surfaces of the folding screen filters 2R, 2L can be sufficiently wiped off by the hot air sent into the chamber 9. The wiped organic solvent can be surely sucked by the solvent discharge pipe 15 and sent to the solvent removing device 14 without being released to the exhaust passage 1.
Further, by connecting the pair of folding screen filters 2R and 2L to each other, when one folding screen filter 2R advancing into the exhaust passage 1 is withdrawn into the filter regeneration chamber 3R, the filter regeneration chamber 3L The other folding screen filter 2L housed in the room can be automatically advanced to the exhaust passage 1. When a direct combustion type or catalytic combustion type deodorizing device is used as the solvent removing device 14, the installation of the hot air generating device 10 can be omitted. That is, if hot deodorizing gas generated by burning and decomposing the organic solvent by the solvent removing device 14 which is a direct combustion type or catalytic combustion type deodorizing device is sent to the filter regeneration chambers 3R, 3L, the hot air generating device 10 Need not be provided separately.
