The method aims at the problem that the activated carbon block 44 cannot be regenerated by introducing steam into the cleaning cylinder 42 in the actual use process.
When steam needs to be injected into the cleaning cylinder 42, firstly, exhaust gas in the honeycomb duct body 1 enters the heating box 52 through the air supply pipe 51, then water in the heating box 52 is clamped and heated, after clamping, the steam in the heating box 52 flows into the cleaning cylinder 42 through the flow pipe 54, then the saturated activated carbon blocks 44 in the cleaning cylinder 42 are treated by the steam, the aim of regenerating the activated carbon blocks 44 is achieved, and the exhaust gas heated by the heating box 53 flows into the heat exchanger 2 through the return pipe 56 for subsequent treatment.
The waste gas flowing into the heating box 52 through the air supply pipe 51 continuously heats the water in the heating barrel 53, so that the steam generated by the water enters the cleaning barrel 42 through the flow pipe 54, and the steam blows off the activated carbon blocks 44 for regeneration, so that the activated carbon blocks 44 can be recycled for a plurality of times.
As shown in fig. 8, 9 and 10, the pressurizing mechanism 57 includes a mounting cylinder 571 fixed in the middle of the flow tube 54, a sealing cylinder 572 is fixedly installed in the mounting cylinder 571, a reciprocating disc 573 is slidingly connected in the sealing cylinder 572, a pushing spring 574 is fixedly installed at the bottom of the reciprocating disc 573, limiting blocks 575 are fixedly installed on the surfaces of two sides of the reciprocating disc 573, the surfaces of the limiting blocks 575 are slidingly connected with the mounting cylinder 571, and a stabilizing mechanism 576 is arranged at the bottom of the sealing cylinder 572.

The problem of low treatment speed of the activated carbon block 44 caused by insufficient steam pressure in the actual use process is solved.
In the process of heating the water in the heating barrel 53 by the waste gas, the generated steam continuously flows towards the inside of the sealing barrel 572, the steam entering the inside of the sealing barrel 572 can push the reciprocating disc 573, the reciprocating disc 573 moves to enable the push spring 574 to shrink, when the reciprocating disc 573 moves out of the inside of the sealing barrel 572, the reciprocating disc 573 can not seal the sealing barrel 572 any more, and then the steam in the sealing barrel 572 rapidly flows towards the inside of the cleaning barrel 42 under the action of pressure, so that the impact effect of the steam on the filtering holes can be increased, and the regeneration effect on the activated carbon blocks 44 is better.
As shown in fig. 8, 9 and 10, the stabilizing mechanism 576 includes a connecting rod 5761 fixed to the bottom of the mounting cylinder 571, a first magnet 5762 is fixedly mounted at one end of the connecting rod 5761, a second magnet 5763 is fixedly mounted on the surface of the bottom of the reciprocating disc 573, and the first magnet 5762 and the second magnet 5763 are located on the same line.
The problem that the steam cannot continuously flow because the reciprocating disc 573 enters the sealed pot 572 immediately after the steam pressure inside the sealed pot 572 is reduced in the actual use process is solved.
When the reciprocating disc 573 moves downwards under the pushing of steam, the second magnet 5763 is driven to move downwards, and when the second magnet 5763 moves downwards to one side of the first magnet 5762, the second magnet 5763 and the first magnet 5762 are matched with the pushing force of the steam, so that the purpose of positioning the reciprocating disc 573 is achieved, when the air pressure of the steam is completely eliminated, the reciprocating disc 573 is driven by the pushing spring 574 to seal the inside of the cylinder 572 to separate the steam again, the pressure of the steam is increased, and the problem that the existing reciprocating disc 573 is reset after part of the steam is discharged when the steam is discharged in a limiting mode, so that the steam cannot continuously flow is avoided.
The using method comprises the following steps: when the device is used, firstly, after the activated carbon block 44 is saturated, the separation plate 43 is driven to rotate through the rotating motor 46, the separation plate 43 drives the activated carbon block 44 on two sides of the separation plate 43 to change positions, after the change, the air supply pipe 51 is started, waste gas in the honeycomb duct main body 1 flows into the heating tank 52 through the air supply pipe 51 to heat water in the heating tank 53, water vapor generated by heating enters the sealing barrel 572 through the flow pipe 54, the reciprocating disk 573 is pushed in the sealing barrel 572, the reciprocating disk 573 moves towards the connecting rod 5761 under the pushing of the vapor, the second magnet 5763 is driven to move while the reciprocating disk 573 moves, when the second magnet 5763 moves to one side of the first magnet 5762, the first magnet 5762 and the second magnet 5763 interact, and the pushing force of the matched vapor simultaneously position the reciprocating disk 573, and when the pushing force of the vapor is insufficient, the pushing of the pushing spring 574 is enabled to reset the reciprocating disk 573, the vapor enters the inside the cleaning barrel 42 through the flow pipe 54 to move towards the connecting rod 5761, and the foreign matters can be removed from the surface of the activated carbon block 44 through the electric scraping rod 484, and the foreign matters can be removed from the surface of the activated carbon block 44 through the electric scraping control rod.
