When it is necessary to discharge slag and discharge water, close the butterfly valves on the air inlet 2, air outlet 3 and flushing port 5, open the butterfly valve at the slag discharge outlet 4, and water and impurities will flow out from the slag discharge outlet 4 into the ditch , is washed away by the water in the ditch, and will not affect the environmental sanitation in the roadway. If the horizontal slag discharger is clogged, close the butterfly valves on the air inlet 2 and the air outlet 3, open the butterfly valves on the slag discharge outlet 4 and the flushing port 5, and inject flushing into the cylinder 101 from the flushing port 5 Fluid to wash out the impurities in the cylinder 101. Since the slag discharge outlet 4 is located at the lower part of the horizontal slag discharge device and lower than the flushing port 5, no impurities will appear in the horizontal slag discharge device after flushing with flushing liquid.
