Efficient cyclone dust collector

Abstract

The invention belongs to the technical field of industrial environmental protection, and particularly relates to an efficient cyclone dust collector which comprises a support, a barrel, an air inlet, an air outlet and a dust removal port, the barrel is composed of an inner barrel and an outer barrel, the inner barrel comprises an end socket, a cylindrical shell and a conical shell, and the outer barrel comprises a top cover, a cylindrical shell and a conical shell. According to the cyclone dust collector, an exhaust channel in a low-speed airflow area in the center of the cylindrical shell of the cyclone dust collector in the prior art is removed, so that the radius of the barrel is effectively reduced, and the centrifugal force borne by dust particles in the cyclone dust collector is increased; and an exhaust channel is innovatively changed to be between the inner barrel and the additionally arranged outer barrel, so that the sectional area of the exhaust channel is increased, the flow speed of exhausted gas is reduced, the proportion of fine-particle dust taken away by the exhausted gas is effectively reduced, and the dust removal effect of the cyclone dust collector is improved.

Description

technical field [0001] The invention belongs to the technical field of industrial environmental protection, in particular to a high-efficiency cyclone dust collector. Background technique [0002] The cyclone dust collector uses the rotating motion of the dust-laden airflow to separate the dust particles from the airflow under the action of centrifugal force. It has the advantages of simple structure, compact equipment, low cost and convenient maintenance. It is widely used in metallurgy, mining, chemical industry, food, etc. Processing, material drying and many other fields; [0003] The dust removal mechanism of the cyclone dust collector is: the dust in the rotating airflow is thrown to the inner wall of the cylindrical cylinder of the dust collector by the centrifugal force, and under the combined action of gravity, the reaction force of the inner wall of the cylinder to the dust particles, the centripetal force, and the airflow, the dust moves along the cylindrical cyli...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the cyclone dust collector in the prior art is that the dust below a certain particle size cannot be completely removed only by the cyclone dust collector, and it needs to be superimposed on expensive dust collectors such as a bag filter and an electrostatic precipitator to reach the national promulgated dust collector. Emission standards; although it is difficult to meet the emission standards promulgated by the state in most industries with only cyclone dust collectors, if cyclone dust collectors can reduce some of the above-mentioned defects, at least the number or size of the next-level dust collectors can be reduced, thereby greatly reducing Equipment investment and site occupancy are technical problems that the industry has been trying to solve for many years but has not been able to solve.
