Vibrating and backflushing integrated bag type dust remover

Abstract

The invention relates to the field of dust removers, provides a vibrating and backflushing integrated bag type dust remover, and aims to reduce dust attachment and enable equipment to operate for a long time. The vibrating and backflushing integrated bag type dust remover comprises a shell, a filter bag, a mechanical vibrating device and a gas distribution structure, wherein a dust-containing gas inlet is formed in the lower part of the shell; a purified gas outlet is formed in the upper part of the shell; a pulse backflushing device is also arranged in the shell; a backflushing pipe of the pulse backflushing device corresponds to the purified gas outlet; the pulse backflushing device comprises a pulse controller, an electromagnetic valve, the backflushing pipe and a gas pocket; the pulse controller is connected with the electromagnetic valve; the backflushing pipe is connected with the gas pocket; and the electromagnetic valve is arranged on a connection pipeline between the backflushing pipe and the gas pocket. By the vibrating and backflushing integrated bag type dust remover, mechanical vibrating and pulse backflushing is integrated, so that accumulated dust on the surface of the filter bag can be cleared away, the operation resistance of the equipment is reduced, and the production capacity of the equipment is improved.

Description

technical field [0001] The invention relates to the field of dust collectors, in particular to a low-resistance mechanical rapping and pulse blowback integrated bag-type dust collector. It can work continuously or periodically to realize the removal of agglomerated dust on the surface of the filter bag. It is widely used in petroleum, chemical, metallurgy, energy, environmental protection and other industries. Background technique [0002] At present, conventional mechanical vibrating bag dust collectors mostly use upper part vibrating or waist vibrating to clean dust; the air flow direction adopts inner filter operation, the dust-laden gas flows from the inside of the filter bag to the outside of the filter bag, and the dust is separated in the filter bag. Inside. During the operation of the equipment, the dust is agglomerated on the inner surface of the filter bag, and the resistance of the equipment is relatively large. The agglomerated dust is not easy to fall off with...

AI Technical Summary

Problems solved by technology

A mechanical rapping bag filter with external filter operation in the airflow direction can overcome the above problems, but in view of the service life of the filter bag, the mechanical rapping frequency and amplitude should not be too fast and too large

When purifying certain gases containing fine dust, the dust adhering to the surface of the filter bag is not easy to remove, and the resistance of the filter bag increases rapidly as the operation time goes by.
