A Dust Collector Group Convenient for Unloading and Sealing

Abstract

The invention discloses a dust remover group facilitating ash discharging and sealing. The dust remover group comprises a ring-shaped ash conveying pipe, wherein a plurality of dust remover units are arranged on the ash conveying pipe; an ash discharging outlet in the lower portion of each dust remover unit is connected with the ash conveying pipe; a ring-shaped slide track is arranged on the side surface of the ash conveying pipe; a magnetic sliding block is arranged on the slide track; and the magnetic sliding block synchronously drives ash scraping devices of which the magnetisms are different in the ash conveying pipe; and the ash conveying pipe is provided with a raised ash discharging opening and an ash discharging pipe with certain inclination or radian. The dust remover group consisting of the dust remover units shares the ash conveying pipe; the magnetic sliding block drives the ash scraping devices to move so as to realize intermittent ash discharging; and ash columns which have a certain height and are in a dense state are formed in the ash discharging opening and in the ash discharging pipe, low-temperature air flow is effectively prevented, and the technical effect of ash sealing is guaranteed. The dust remover group is novel and skillful in design; ash can be discharged safely and conveniently; and the application value is high.

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 the following defects exist 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
