[0048] 100 The reaction processing assembly also includes an L-shaped air inlet pipe 106 and a straight exhaust pipe 107. The L-shaped air inlet pipe 106 is fixedly installed at the bottom of the processing cylinder 101, and the straight exhaust pipe 107 is fixedly connected to the top of the cylinder cover 102.

[0055] Working principle: The generated waste gas is introduced through the L-shaped inlet pipe 106, and then the waste gas comes into contact with the bottom adsorbent layer 203 through the through hole 205 on the container cylinder 201. At this time, the adsorbent particles adsorb impurities in the waste gas. Then the waste gas is diverted through the upper metal mesh 204. The waste gas flows through the adsorbent layer 203, metal mesh 204, adsorbent layer 203, metal mesh 204, and finally back through the adsorbent layer 203. The gas after impurity removal is discharged through the through hole 205 on the cap 202, and then discharged through the straight exhaust pipe 107. When it is necessary to replace the adsorbent layer 203, remove the cap 102 and then hook 306. Remove the cylindrical rod 305, then hook the hook 306 onto the U-shaped buckle 307 and pull upwards to remove the container 201 from the processing cylinder 101. Then rotate the cap 202, at which point the locking block 303 moves in the strip locking groove 304. When the locking block 303 rotates to the receiving groove 302, pull upwards to remove the cap 202. Then remove the adsorbent layer 203 and the metal mesh 204, and take out a new adsorbent layer 203 and a new metal mesh 204 to install in the container 201 for smooth filling. Then repeat the above process in reverse to install the container 201 into the processing cylinder 101. This step achieves a highly efficient and uniform impurity removal effect.
