Drainpipe: select the material the same with blast pipe for use, with the same size of U type pipe, make a pipeline, the water after will separating through dirt, gas enters in the electric cleaner bottom cycle pond.
According to gas leakage preventing effluent treatment plant described in the utility model, be preferably, described elementary ash discharge storehouse is hollow cuboid container.
According to gas leakage preventing effluent treatment plant described in the utility model, be preferably, described ash ejector is the filter net type structure.
According to gas leakage preventing effluent treatment plant described in the utility model, be preferably described blast pipe and terminal vertical linking to each other of described U type pipe.
According to gas leakage preventing effluent treatment plant described in the utility model, be preferably, described level ash discharge storehouse eventually and described elementary ash discharge storehouse are horizontally disposed.
According to gas leakage preventing effluent treatment plant described in the utility model, be preferably, described hole capital after selling all securities and the described ash discharge of level eventually storehouse are horizontally disposed.
The beneficial effects of the utility model are; this device can prevent that coal gas from leaking near circulating water pool; guaranteed the safety of operating personnel's working environments; make the water quality raising of electric cleaner cycling use of water reduce the shutdown maintenance that causes because of grieshoch increase in shower nozzle obstruction, the pond simultaneously; both improve the operational efficiency of deduster, reduced maintenance cost again.
