The dust removal efficiency of the horizontal water film dust remover is related to the structural size of the horizontal water film dust remover; in particular with respect to the pitch, the diameter of the helix of the helical guide vanes 27; the smaller the spiral diameter and the pitch of the guide vane are, the higher the dust removal efficiency is, but the larger the resistance loss is; the practical operation shows that the dust removal efficiency of the horizontal water film dust remover can reach 85-92%.

In the horizontal cyclone water film dust collector, the quality of a water film also has great influence on the dust collection efficiency; the quality of the water film is mainly determined by the flow rate of the flue gas in the spiral channel and the water level in the water tank 28, and at a certain water level, the flow rate of the flue gas corresponds to a good flow rate; the flue gas flow velocity is too low, and the formed water film is possibly too thin or can not form a water film; the flue gas flow velocity is too high, and the formed water film is too thick, so that the phenomenon that the outlet flue gas carries water is aggravated; therefore, the quality of the water film can be determined by adjusting the flow rate of flue gas or the water storage level of the cylinder; but when the water level is increased, the flow rate of the flue gas should be properly increased.
