Problems solved by technology

Ordinary bag filter mainly includes a filter chamber, the upper end of the filter chamber is sealed by a porous plate, each through hole of the porous plate extends downwards a filter bag, the lower end of the filter bag is closed, and the upper end is connected to the upper chamber above the filter chamber; The lower end of the filter chamber is connected to the ash hopper; the lower part of the filter chamber has an air inlet connected to the filter chamber, and the upper chamber has an air outlet; after the dusty gas enters the filter chamber from the air inlet, it can only pass through the filter bag and then enter the upper chamber. And it is discharged from the air outlet. During this process, the dust is filtered on the outer surface of the filter bag; as the dust removal operation progresses, the dust on the surface of the filter bag will accumulate more and more, which will lead to a rapid decline in filtration efficiency; therefore, the current bag filter The upper chamber is also equipped with an injection system. During the dust removal process, the air filter is stopped at regular intervals, and the injection system is started to spray the inside of the filter bag, so that the dust attached to the surface of the bag falls outward; it can be seen , this kind of bag filter cannot carry out the dust removal operation continuously, and the dust removal efficiency is greatly limited; and the cost of the injection system is relatively high

Abstract

The invention provides an efficient bag type dust remover which comprises a filter chamber. The upper end of the filter chamber is closed by a perforated plate, and the lower end of the filter chamber is communicated with a dust hopper; an air inlet is formed in the lower portion of the filter chamber; an upper chamber is arranged above the filter chamber, and an air outlet is formed in a side surface of the upper chamber; a filter bag downwardly extends at each through hole of the perforated plate; air in the filter chamber only can flow into the upper chamber after flowing through the filter bags; the air inlet is communicated with an air distributing cavity on the lower portion of the filter chamber, the air distributing cavity is upwardly communicated with exhaust pipes which are parallel to the filter bags, and at least one exhaust pipe is arranged beside each filter bag; ports of the exhaust pipes extend to be close to the perforated plate; side holes which face the filter bags are axially distributed in the surfaces of the exhaust pipes. The efficient bag type dust remover has the advantages that continuous dust removal operation can be implemented by the aid of the dust remover, only little dust on the surfaces of the filter bags can be kept all along, and the efficient bag type dust remover is high in dust removal efficiency and low in cost.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a bag filter. Background technique [0002] The bag filter is a commonly used industrial dust collector, which is widely used because of its simple structure and low cost. Ordinary bag filter mainly includes a filter chamber, the upper end of the filter chamber is sealed by a porous plate, each through hole of the porous plate extends downwards a filter bag, the lower end of the filter bag is closed, and the upper end is connected to the upper chamber above the filter chamber; The lower end of the filter chamber is connected to the ash hopper; the lower part of the filter chamber has an air inlet connected to the filter chamber, and the upper chamber has an air outlet; after the dusty gas enters the filter chamber from the air inlet, it can only pass through the filter bag and then enter the upper chamber. And it is discharged from the air outlet. During this ...
