[0026] In the process of working, the tail gas generated by the tail gas exhaust furnace 1 is discharged from the round pipe one 11, and the filter screen 421 of the moving plate 42 filters the impurities with larger particles in the tail gas. When a large amount of impurities are filtered, the electric cylinder 41 can drive the moving plate 42 to move up and down, pushing the filter screen 421 that has not been filtered into the filtering process. At the time of pushing, the moving plate 42 can always adhere to the outlet of the tail gas discharge, which can relatively reduce the overflow of the tail gas. After the tail gas passes through the moving plate 42 and enters the round pipe two 21, it will be collected in the square pipe 22. The water curtain formed by the spray heads 61 at the top of the square pipe 22 can dissolve the sulfur dioxide in the tail gas. The water that dissolves the sulfur dioxide will be discharged in the drain pipe 62 under the action of gravity. The tail gas containing carbon monoxide will gather to the left side to lift the air bag 51, and will be discharged from the gas ejection end 511 of the air bag 51. The ignition assembly 53 ignites the tail gas containing carbon monoxide discharged from the gas ejection end 511 to convert the carbon monoxide into carbon dioxide. At this time, the discharged tail gas reaches the standard that can be discharged into the atmosphere. The ignition assembly 53, the electric cylinder 41, the spray head 61, the filter screen 421 and the related pipelines and electric control connections are prior art, and their working principles will not be described here.

[0027] Through the above steps, the vertically arranged filter screen 421 can be quickly switched to block the tail gas and reduce the overflow of the tail gas. The air bag 51 that is vertically inflated upwards can reduce the deflection caused by gravity, facilitate the ignition of the ignition assembly 53, and facilitate the replacement of the moving plate 42 with the filter screen 421 that has been used. This solves the problem in the prior art that the storage bag will sag under the action of gravity during use, which can cause difficulty in ignition and burning, and the ignition nozzle can easily burn the storage bag and cause danger.
