Description

Air box type dust remover

Technical Field

The utility model relates to the technical field of dust removal, in particular to an air box type dust remover.

Background

Along with the increasing attention of society to environmental protection problems, each industrial enterprise responds to the national call and matches a dust removal system for the original project and the newly built project successively. The unique three-state ash cleaning method of the air box type bag dust collector expands the application range of the dust collector. The dust collector not only can purify common dust-containing gas, but also can treat high-concentration dust-containing gas, effectively improves the dust collection efficiency of the dust collector, and prolongs the service life of the filter bag. Becomes an ideal product for protecting the environment of enterprises.

The air box type dust remover mainly comprises a shell, an ash bucket, an ash discharging device, a bracket, pulse ash cleaning and an electric control part. The shell is divided into 2 parts by a flower plate. The upper part of the pattern plate is a gas-purifying chamber, and the lower part of the pattern plate is a filtering chamber (also called a filtering bag chamber). The shell mainly bears the weight of the filter bag, the filter bag absorbs the weight of dust, and the side wall plate of the shell also bears the negative pressure generated by the fan on the dust remover and the wind load in the working environment. The side wall panels of the housing are therefore provided with a certain strength to carry the vertical loads and lateral forces generated during operation. If the shell wall plate is simply thickened, the steel content of the equipment is increased, the equipment cost is increased, but the strength of the shell wall plate is not obviously improved. At present, the conventional practice is to weld reinforcing ribs on the surface of the side wall plate, and the side wall plate and the reinforcing ribs form a combined section to jointly bear the load on the shell.

Because the products among the same rows are seriously homogenized, and the market competition is strong, various manufacturers put forward cost benefits in a dispute. Besides reducing the purchase cost, each manufacturer proposes to fully exert the bearing capacity of the steel. Under the condition that the main material meets the use requirement, part of enterprises reduce the specification of the reinforcing ribs on the side wall plate. Wherein, the reinforcing ribs are changed into angle steel 50 times 5. Under the condition that the dust removal system is in normal operation, the dust remover shell is not deformed. In case of failure, such as the off-line valve not being normally opened, the housing collapses. After the shell is deflated, on-site refurbishment is very difficult and affects the production of the host with serious consequences.

There is a need to propose new alternatives that reduce the consumption of steel and provide the sidewall panels with good flexural strength.
