Dust remover group

Abstract

The invention discloses a dust remover group. The dust remover group comprises a circular ring-shaped dust conveying pipeline, wherein a plurality of dust remover units are arranged on the dust conveying pipeline; dust discharge outlets in the lower parts of the dust remover units communicate with the dust conveying pipeline; an annular slide rail is arranged on the side surface of the dust conveying pipeline; magnetic sliding blocks are arranged on the slide rail; the magnetic sliding blocks synchronously drive dust scraping devices with different magnetism in the dust conveying pipeline; and an upward dust discharge hole and a dust outlet pipe which has certain inclination or radian are arranged on the dust conveying pipeline. According to the invention, the dust remover group composed of the plurality of dust remover units utilizes the dust conveying pipeline in common; the magnetic sliding blocks drive the dust scraping devices to move to intermittently operate to discharge dust; dust pillars which have certain height and are in a dust denseness state are always formed in the dust discharge hole position and the dust outlet pipe, so that low-temperature airflow is effectively prevented, and the technical effect of dust sealing is guaranteed; and the dust remover group is ingenious in design, can safely and conveniently discharge dust, and is high in application value.

Description

technical field [0001] The invention relates to the technical field of dust collectors, in particular to a dust collector group convenient for dust unloading and sealing. Background technique [0002] At present, high-temperature dust-containing gases are often produced in chemical, petroleum, metallurgical and other industries, and dust collectors are the most important dust removal process equipment. Dust collectors used in special flue gas working conditions (such as containing coal gas, etc.) have very high air tightness requirements due to the need to maintain high temperature conditions, and the ash unloading part is one of the key points to ensure air tightness. The currently adopted ash unloading method is a manual flapper valve and an electric air locker. When dealing with special flue gas conditions, the ash unloading method of the dust collector is a manual flapper valve and an electric airlocker. The ash method is a major air leakage point for the dust collector...

AI Technical Summary

Problems solved by technology

The ash unloading device for the above-mentioned dust collector is equipped with two asynchronous pneumatic valves and an intermediate chamber, so that the ash first enters the intermediate chamber through the first pneumatic valve, then closes the first pneumatic valve and then opens the second pneumatic valve to discharge the ash. In order to ensure that the dust collector will not produce air leakage during the ash unloading process, the principle design is feasible, but there are the following defects in the actual use process: 1) Normal operation will generate a large amount of deposited dust, and the dust unloaded from the intermediate bin of ash unloading A large amount of dust accumulates and needs to be transferred, but the speed of self-weight ash unloading is slow, and the removal is not complete; 2) The valve closing effect is not good under high temperature and high pressure conditions, and there are often cases of lax closing, which is difficult to implement effectively; Further improvements and innovations have been made in ash unloading and anti-low temperature gas entry to ensure safe operation of equipment
