Detailed Description

In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

Referring to fig. 1 and 2, a DMF waste gas treatment apparatus includes a DMF recovery tower 1 and a spraying device 2 disposed inside the DMF recovery tower 1, where the spraying device 2 may adopt a mounting plate with a mesh structure, a water pipe and a water mist nozzle are disposed on the mounting plate, or a water pipe structure may be directly adopted, the water pipe is provided with the water mist nozzle, the bottom of the DMF recovery tower 1 is provided with an air inlet, the top of the DMF recovery tower 1 is provided with an air outlet, the top of the DMF recovery tower 1 is provided with a manual chain block 3, the chain block 3 may also adopt an electric chain block, but internal components of the electric chain block 3 may be corroded by the gas or the water mist, the electric chain block 3 needs to be maintained, both sides of the spraying device 2 are provided with a roller 4, the inner side wall of the DMF recovery tower 1 is provided with two oppositely disposed chutes 5, the chutes 5 are recessed and vertically disposed toward the inner side wall where the chutes are located, the roller 4 is arranged in the sliding groove 5, the top of the spraying device 2 is provided with a connecting part 6 matched with the hook on the chain block 3, the connecting part 6 can be a barb matched with the hook on the chain block 3, and the spraying device 2 is connected with an external water inlet hose 7.

The use principle is as follows:

when needs maintain spray set 2, pulling chain calabash 3, descend spray set 2 from the top of DMF recovery tower 1 to maintain, need not maintenance person and scrambles, and the setting of gyro wheel 4 and spout 5, one of which, can be stable with smooth and easy go up and down spray set 2, and its two prevents that spray set 2 from taking place to rock under hydraulic effect when the water spray.

Referring to fig. 1 and 2, the spraying device 2 of the present embodiment, except for the roller 4, is not in contact with the inner sidewall of the DMF recovery tower 1.

Adopt this technical scheme, can prevent to go up and down to spray set 2 with chain calabash 3, spray set 2 and DMF recovery tower 1 inside wall take place the friction, lead to the condition emergence that can't go up and down to spray set 2.
