Centrifugal guide vane

Abstract

The invention is concerned with a kind of radial guide vane, belonging to environment friendly establishment technology field to remove smoke and gas. It has a body which having a vertical tube as upper part and a bugle shape as lower part and a group of vane that setting on the ektexine of body. There is a connecting loop outside of the body and it extends to form projecting edge as skirt borderand the edge connects with vane. Because of the connecting loop, so when the gas with dust passing through the channel among the vanes, the enter angle of gas will change by the wall of projecting edge and change into solid enter from plane of vane's surface. This increases the enter area and avoids gas with dust escaping form the lower side of vane and keep the state of gas with dust into the revolving canister, prolong the rotating time in the revolving canister to keep more dust falling to taper ash gather filler.

Description

technical field [0001] The invention relates to a centrifugal guide vane, which is used in cyclone separation and dust removal equipment for dust removal of flue gas in iron and steel enterprises such as pelletizing plants, coking plants, and sintering plants, and belongs to the technical field of environmental protection facilities for dust removal of flue gas. Background technique [0002] Since the centrifugal guide vane and the swirl cylinder are usually referred to as the guide and the cyclone respectively, the centrifuge composed of the centrifugal guide vane and the swirl cylinder is also usually called a cyclone. Regarding the centrifuge, it can be seen from Chinese patent ZL98226235.3, which is based on the centrifugal guide vane ( Patent called guide) and centrifugal conduit (also known as inner cylinder) are made as a whole, which causes inconvenience to the maintenance and repair of the swirl cylinder and the cleaning of dust, so it is conceived to separate the c...

AI Technical Summary

Problems solved by technology

[0006] After further exploration by the applicant, it was found that the above-mentioned centrifugal guide vanes have advantages and disadvantages, that is, because the angle at which the dust-laden air enters the swirl cylinder is single, the passage area of ​​the dust-laden air passing through the centrifugal guide vanes is small, and the resistance loss is large, thereby reducing The rotation strength of the dust-laden air in the cyclone cylinder cannot make the fine dust particles be separated from the flue gas by sufficient separation force in the cyclone airflow, that is, it is difficult to make the fine dust particles settle in the cyclone cylinder and enter the conical ash filter. bucket, resulting in a high amount of fine dust in the purified air, so the dust removal efficiency is still not enough to achieve the ideal level that people expect
