Problems solved by technology

[0002] At present, hydrocyclones, cyclone dust collectors, and aerosol separators are widely used in production activities in today's society, while the efficiency of ordinary separators is lower than 80%, and the efficiency of circulating high-efficiency dust collectors is lower than 95%.
In the conventional wet separator, the aerosol entrainment is serious, which not only pollutes the environment, but also causes external corrosion to the equipment. In sand making, sandblasting, grinding and cement plants, etc., where dry dust removal is required, a large amount of silicon-containing floating dust Suspended in the atmosphere of the factory, silicosis occurs to the body. The reason is that the central air column in the separator is unstable, the separation procedure is single, the internal flow field is short-circuited, and many other problems cause low separation efficiency.

Abstract

A ring current cyclone separator comprises outside cyclone barrel with tangential inflow opening at the top, exhaust opening at the lower side, inner cyclone barrel inside with top cover connected with outside cyclone barrel top cover through ring current tube, cyclone cavity formed between the outside and inside cyclone barrels and ring current tube, with the inflow opening and the cyclone cavityconnected. It is simple in structure, with low cost and extensive application.

Description

technical field [0001] The invention relates to a cyclone separator, in particular to a cyclone separator with tangential inflow and axial flow distribution. Background technique [0002] At present, the hydrocyclone separator, cyclone dust collector and aerosol separator in today's social production activities are widely used, while the efficiency of ordinary separators is lower than 80%, and the efficiency of circulating high-efficiency dust collectors is lower than 95%. In conventional wet separators, aerosol entrainment is serious, which not only pollutes the environment, but also causes external corrosion to the equipment. Suspended in the atmosphere of the factory, silicosis damage occurs to the body. The reasons are that the central air column in the separator is unstable, the separation procedure is single, and the internal flow field is short-circuited, etc., which cause its low separation efficiency. SUMMARY OF THE INVENTION [0003] In order to overcome the def...
