Description

Technical Field

[0001] The invention relates to the technical field of tail gas adsorption methods, and in particular to a method for prolonging the service life of an adsorbent in an adsorption-type tail gas treatment device. Background Art

[0002] At present, the more widely used scheme for removing harmful substances by solid adsorption is: the device body is divided into a packing area and an air inlet suspended area by a porous plate, the packing area is filled with packing, and an air inlet is set on one side of the air inlet suspended area; air is introduced through the through holes of the porous plate.

[0003] However, in the adsorption method of the existing exhaust gas adsorption device, after being used for a period of time, the internal filler at the air intake part becomes hardened due to aging of the adsorbent and the obstruction of the passage and cannot be used. The filler needs to be replaced in advance, while the filler at the exhaust part is not fully utilized, resulting in a shortened lifespan and a waste of resources. Summary of the invention

[0004] In view of the above problems, the purpose of the present invention is to provide a method for extending the service life of the adsorbent in an adsorption-type exhaust gas treatment device. By arranging a lifting plunger assembly in the device body, air intake can continue to be maintained when hardening occurs on the upper part of the porous plate, thereby extending the practical life of the filler.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] The method for extending the service life of an adsorbent in an adsorption-type tail gas treatment device according to the present invention comprises the following steps:

[0007] A porous plate is arranged in the device body, and the porous plate divides the device body into a packing area and an air intake suspended area, and the exhaust gas enters through the air intake port on one side of the air intake suspended area; the exhaust gas enters the packing area through the porous plate, passes through the packing area, is adsorbed by the adsorption packing, and is discharged from the exhaust port;

[0008] In the case of compaction on the upper part of the porous plate, a lifting plunger assembly is arranged in the device body, and the tail gas enters the packing area through the lifting plunger assembly and is adsorbed by the adsorption filler and then discharged from the exhaust port.

[0012] Start the telescopic device to make the plunger valve rise like a piston in the porous plunger. When the plunger valve passes over the through holes of the bottom layer of the porous plunger, the exhaust gas enters the packing area from the through holes of the bottom layer; when the plunger valve passes over the through holes of the middle layer of the porous plunger, the exhaust gas enters the packing area from the through holes below the middle layer; when the plunger valve passes over the through holes of the top layer of the porous plunger, the exhaust gas enters the packing area from the through holes below the top layer.
