Coal crusher dust suppression device

Abstract

A dust suppression device for a coal crusher, which is installed on a material guide trough, and includes a vortex chamber, a circulation chamber, a circulation pipe, a dust gas energy dissipator, a circulation pipe inspection hole cover, a dust diverter, a fine dust adsorption and separation system, and a tail seal Curtains and manhole doors, the vortex chamber is between the two drop pipes and above the feed trough, and is integrated with the feed pipe and the feed trough; the circulation chamber is set near the front end of the feed trough Next to the first drop tube, it communicates with the lower part of the first drop tube, and connects with the first drop tube and the guide groove as a whole. The upper part of the first drop tube is a coal crusher, and the upper part of the circulation chamber passes through The circulation pipe is connected with the coal crusher, and the circulation chamber is divided into a main circulation chamber and a secondary circulation chamber by a built-in partition. The invention can well solve the problem of dust raising in the transfer station of the coal crusher room, effectively suppress and lower the dust, and make the dust concentration in the workplace at the transfer station of the coal crusher room comply with the national standard. It not only prevents the dust from polluting the environment, but also protects the vital interests of the workers at the post.

Description

technical field [0001] The invention relates to an environmental protection device for dust suppression in a transfer station of a coal crusher room, in particular to a dust suppression device for a coal crusher. Background technique [0002] The coal crusher is a commonly used lump coal crushing equipment, which can break the lump coal into small lump coal or pulverized coal. The coal crusher has the advantages of high crushing efficiency and stable operation, but it will produce A large amount of induced wind, the induced wind brings a large amount of dust, causing a large amount of flying dust to form at the transfer station below the coal crusher. The turbulent air flow caused by the induced wind makes the fine dust flow around and becomes the main dust source, causing dust to fly and pollute environment. [0003] At present, there are various dedusting methods for the coal crusher room transfer station, such as wet dedusting methods such as negative pressure induction ...

AI Technical Summary

Problems solved by technology

After the implementation of these dust removal technologies, they will receive a certain dust removal effect in the short term, but after a period of operation, they will continue to decline, so that they will be put on hold in the end.

Therefore, the problem of dust in the transfer station of the coal crusher room has not been solved well.
