When the height difference between the water inlet and the water outlet of the gas-liquid coupling water pump 3124 is two meters (the pressure difference is 0.2), the area of the water inlet is 44 percent of the sectional area of the pipeline of the water pump 3124, that is to say, the water level difference of two meters can suck up 56 percent of gas, generally, the operation is more stable and reliable when the water level difference is 50 percent. When the height difference between the water inlet and the water outlet of the gas-liquid coupling water pump 3124 is 10 meters (differential pressure 1.0), the volume of the gas reaches the position of the water pump 3124 and is only half of the volume of the gas under normal pressure, therefore under the difference condition of the water inlet and the water outlet of 10 meters, the volume of the gas reaches the position of the water pump 3124 and is reduced by more than one time than that of the gas of two meters, therefore, the water pump 3124 can be maintained in the normal working condition by keeping the same water-gas proportion of the position of the water pump 3124, the gas suction amount of the water head difference of 10 meters can reach 80 to 85 percent, namely, the water inlet area is only 20 to 15 percent of the pipe area of the water pump 3124 at the time of the water level difference of 10 meters. Because the gas viscosity is low and the liquid viscosity is high, when the gas-liquid coupling water pump 3124 is started, the gas-liquid coupling water pump 3124 can not be started directly like starting the ordinary water pump 3124, otherwise the water pump 3124 can directly and instantly suck a large amount of gas due to the low gas viscosity and the high flow rate, and the dynamic sealing can not be realized, so that the starting of the gas-liquid coupling water pump 3124 needs to use a speed regulator or a frequency converter, the water pump 3124 can be started only by slowly increasing to the standard rotating speed within about ten seconds from the low speed, and the gas-liquid coupling water pump 3124 can finish the work of extracting smoke and dust smoke. The gas-liquid coupling water pump 3124 is corroded by the working environment, it is recommended to use stainless acid-resistant steel to make pump case pump shaft and impeller, the pump case and impeller can also be made of other alloy materials which can not produce cavitation corrosion, of course, it can also be made of plastic, glass, toughened glass, carbon fiber and other materials, and the pump shaft can only be made of metal materials or alloy.

By adopting the method of synchronous sliding of full box outlet and empty box inlet, the excessive sediments in the bottom space of the sediment collection box of the acid-base neutralization reaction chamber 32 can be cleaned.
