Wet scrubber principle and the advantages and disadvantages: making dust dusty gas through contact with droplets or film separated from the gas stream. It has the advantage of simple structure, low investment, small footprint ventilation pipeline company, high collection efficiency, it can be harmful gases while cleaning. Mainly for 1 ~ 5μm dust (inertial impaction), 1μm or less dust (cohesion, diffusion contact with droplets film); drawback is useful in plant material can dry recovery ventilation pipe, mud treatment more difficult, in order to avoid contamination of water ventilation pipeline certification, sometimes you want to set up a dedicated wastewater treatment equipment; washing temperature gas, the temperature dropped ventilation pipes, smoke affects diffusion in the atmosphere. Plumbing vent pipe processing quality requirements: duct and part of the system step by step installation, the stent using boom stand, elevation must be determined according to the drawings and civil baseline, when the hanger is installed, press the center line of the duct to find hanging laying position, cook mark, and then the finished fixing up the boom, boom with the cross arm with the nut, so that in the future adjustments. When the duct is longer, you need to install a row of brackets, the first ends of the boom can be fixed, and then find out where the middle bracket wiring method, and finally click Install.
