[0036] The working principle of the present utility model is as follows: During use, gas enters the tank body 1 through the air inlet pipe 4 and rises.

When maintenance of the spraying mechanism 7 is required, first activate the two motors 13. The output shafts of the motors 13 drive the first lead screws 12 to rotate. The first lead screws 12 drive the corresponding cross plates 11 to slide and rise on the L-shaped brackets 8, so that the connecting collar 10 is driven to rise by the two cross plates 11. The connecting collar 10 slides out of the tank body 1 and drives the cover body 2 to rise. The cover body 2 penetrates through the rectangular frame 9, so that the tank body 1 is opened.

When the spraying mechanism 7 needs to be disassembled, first rotate the two second lead screws 19. The second lead screws 19 drive the clamping blocks 18 to slide into the corresponding grooves 17, so that the clamping blocks 18 slide out of the corresponding clamping plates 16, and the fixation of the clamping plates 16 is released. Subsequently, pull down the spraying mechanism 7, so that the spraying mechanism 7 slides out of the cover body 2, and the clamping plates 16 are driven to slide out of the corresponding clamping grooves 15, and the spraying mechanism 7 is disassembled. Subsequently, a new spraying mechanism 7 can be replaced. By setting it in this way, it is convenient to quickly assemble and disassemble the spraying mechanism 7, thereby facilitating the replacement of the spraying mechanism 7, and thus facilitating the guarantee of the sulfur removal effect by spraying.
