Direct-connection even-flow pulse bag type dust collector

Abstract

The invention relates to a direct-connection even-flow pulse bag type dust collector, which comprises an upper box body, a middle box body, an ash bucket, a skid mount package and an automatic control system. After dust air enters, the dust air which passes through a low efficient filter directly enters an air flow distribution device to be shunted; a filtering frame is arranged in each filtering bag to support the filtering bag to enable filtered purified air to flow to the upper box body; the automatic control system automatically controls a cabinet to close an air inlet valve when the resistance of the filtering bag reaches a certain value, pulse jet is carried out to remove dust on the surface of the filtering bag; an air compression bag and a pulse valve are opened, air filtered by a high efficiency filter directly enters an injection pipe, and dust on the filtering bag which is under the function of pulse external force falls. The air flow distribution device of the direct-connection even-flow pulse bag type dust collector has a reasonable structure, airflow which contains dust is conveyed to the filtering bags on different positions from a front side, side surfaces and the bottom surfaces, so that the washing of the airflow which contains dust for the filtering bags is avoided, and the flowing of the airflow which contains dust from bottom to top is slowed down so as to reduce the secondary attachment of the dust and guarantee the dust removal efficiency of the filtering bags.

Description

technical field [0001] The invention relates to the technical field of dust separation, in particular to a straight-through flow equalizing pulse bag filter. Background technique [0002] Large-scale bag filter is mainly used for flue gas purification of boilers in coal-fired power plants, and can also be used for dust removal of large-scale process equipment in other industries (steel, cement). [0003] At present, the pulse bag type dust collector is a kind of high-efficiency purification equipment commonly used at home and abroad. It has a large air volume. Due to its large scale, it is especially closely related to the production process. Due to the current complex structure, the airflow scours damage the filter bag and troublesome maintenance. , After long-term use, the efficiency of the dust collector decreases. At present, how to improve the operation reliability, structural safety, improve the air distribution effect, and simplify the structure is the only way to imp...

[0003] At present, the pulse bag type dust collector is a kind of high-efficiency purification equipment commonly used at home and abroad. It has a large air volume. Due to its large scale, it is especially closely related to the production process. Due to the current complex structure, the airflow scours damage the filter bag and troublesome maintenance. , after long-term use, the efficiency of the dust collector decreases. How to improve the operation reliability, structural safety, air flow uniformity, and structure simplification is the only way to improve the development of the pulse bag filter.
