Flow guide device for bag filter

Abstract

The invention discloses a flow guide device of a cloth bag type dust remover. The flow guide device of the cloth bag type dust remover comprises a dust hopper, a box body, cloth bags and n flow guide plates, wherein the dust hopper is arranged under a bottom plate of the box body; openings of the cloth bags are formed in the bottom plate of the box body; n+1 groups of ventilation holes are formed in the bottom plate of the box body; the positions of the openings of the cloth bags correspond to the ventilation holes; the ventilation holes are used for communicating the dust hopper with the cloth bags; the flow guide plates are arranged on the inner side wall of the dust hopper and are located between two adjacent groups of ventilation holes; the flow guide plates comprise air shielding plates and air inducing plates; the air guiding plates are located at the bottoms of the air shielding plates; an included angles between each air shielding plate and each air inducing plate is 120-150 degrees; side plates are arranged on two sides of the air shielding plates adjacent to the air inducing plates; an air inlet is formed in the wall of the dust hopper; the plate sides of the air shielding plates are opposite to the air inlet; staggered protrusions are formed in the plate sides of the air shielding plates; n is a natural number being greater than or equal to 1. Through the flow guide device, the airflow distribution uniformity of the dust remover can improved; the re-entrainment of the dust of the dust hopper can be reduced; the operation resistance of the equipment can be reduced; meanwhile, the service life of the cloth bags can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of bag-type dust collectors, and in particular relates to a flow guide device for bag-type dust collectors. Background technique [0002] Bag filter is widely used in various industrial fields due to its advantages of high dust removal efficiency and stable operation performance. Through the extensive use of bag dust collectors, people have found that reducing airflow resistance, prolonging the service life of filter bags, and reducing vibration and noise are urgent problems that bag dust collectors need to solve today. [0003] The baghouse is the executive part of the bag filter, and the airflow distribution in the baghouse is a key factor that determines the working performance and service life of the baghouse. Uneven air flow is likely to cause damage to a certain position of the bag or a certain position of the bag in the bag room, while the role of the bag in other positions is relatively small in the...
