Abstract

The invention discloses a whirlwind water film wet dust removal axial flow fan, composed of an axial flow fan; wherein the rear part of the axial flow fan is connected with a whirl water film dust removal device which is composed of an outer cylinder of the whirlwind water film dust removal device, an inner cylinder of the whirlwind water film dust removal device and a spiral flow deflector. The whirlwind water film wet dust removal axial flow fan has no auxiliary spraying device, high dust removal efficiency, low working resistance and low fan operating cost.

Description

technical field [0001] The invention relates to a blower fan, in particular to a whirlwind water film wet dust removal axial flow blower used for processing dust in coal mine underground, railway and highway tunnel excavation work. Background technique [0002] At present, the wet dedusting fans widely used in my country's coal mine underground, railway and highway tunnel projects need to be equipped with water pumps as auxiliary equipment for spraying. The operating costs of the fans are high, and the nozzles are easy to plug, with large working resistance and poor dust removal effect. . Therefore, it is a technical problem to be solved at present to design a cyclone water film wet dedusting axial flow fan without auxiliary spraying equipment, high dust removal efficiency, small working resistance, and low fan operating cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cyclone water film wet dust removal a...
