It is preferred that, the tower body is made up of glass-reinforced plastic material.
Advantageous effects of the present utility model are：
1st, the utility model can make spray liquid circulated sprinkling wash tail gas, when the contaminants in spray liquid reach necessarily
After concentration, centralized recovery processing can be carried out, vent gas treatment cost, environmental protection and economy remarkable benefit is saved.
2nd, the utility model is designed using double-layer filtering net, and the screen pack of outer layer uses special-shaped spherical structure, can have
Effect prevents discarded object to be fitted in completely on screen pack, and then causes screen pack to block.
3rd, the utility model is additionally provided with relief valve at the position for installing screen pack, even if situation about being blocked in screen pack
Under, also can self pressure relief, prevent from burning out circulating pump.
4th, the utility model shower nozzle uses helical design, and flow is big, and uniform spraying, spray area is big, does not block, and
Shower nozzle is with spray liquid circulation pipe using being threadedly coupled, and convenient dismounting is overhauled.
Brief description of the drawings
