The working principle of the existing water curtain wet dust collector is as follows: utilize the suction of draught fan to send into the air current high pressure that contains the dust in the water curtain dust remover, water curtain dust remover top is equipped with high pressure nozzle, and when the air current got into in the dust remover, gas was from upwards flowing down, and high pressure nozzle can spray water curtain entrapment dirt particle from the top down, and the belt dirt water that forms from this can flow back in the lower part precipitation pond, subsides the separation, and the water purification after the separation is again sent into spray in the dust remover through the water pump and is cyclic utilization. The purified gas is discharged from the upper exhaust pipe.

Although the water curtain wet dust collector has a certain dust removing effect, the water curtain wet dust collector also has the following defects: firstly, the mode of collecting dust particles by the air flow moving from bottom to top and the water curtain spraying from top to bottom cannot enable the water and the air flow to be fully fused, so that some fine dust cannot be removed, and the dust removal effect of equipment is influenced; secondly, the dust remover not only needs to be provided with a draught fan but also needs to be additionally provided with a water pump to form a circulating system, so that the energy consumption in the dust removing process is greatly increased.

Therefore, how to overcome the technical defects of the existing water curtain wet dust collector is one direction that needs to be intensively researched by those skilled in the art.
