Air inlet flow rectifier for bag-type dust collector

Abstract

The invention discloses an air inlet flow rectifier for a bag-type dust collector. The air inlet flow rectifier comprises an air inlet pipe arranged on the side face of an ash hopper of the dust collector, wherein the air inlet pipe is internally provided with a plurality of porous flow equalization boards in the ladder-shaped distribution. The porous flow equalization boards of the air inlet pipe are designed to be ladder-shaped, and thus the airflow velocity of a filter bag chamber is quickly reduced, and the airflow direction is changed so that airflow is uniformly distributed and dusty air is uniformly guided in the ash hopper; the airflow is prevented from directly washing filter bags, so that the service life of each filter bag is prolonged, and the running resistance of the bag-type dust collector is reduced; the inertial setting volume of dust in the dust hopper is increased, the absorbing capacity of the dust on each filter bag is reduced, and same filtering loading is achieved for each filter bag; the filtration resistance of the filter bags and the emission of dusty gas concentration at an outlet are reduced, and the service life of each filter bag is prolonged.

Description

technical field [0001] The invention relates to the field of bag dust collectors, in particular to an air inlet flow equalization device for bag dust collectors. Background technique [0002] The working mechanism of the bag filter is that the dusty air is passed into each ash hopper, and then enters each bag from the ash hopper upwards, the dust particles are filtered and collected by the ash hopper, and then the filtered air is discharged into the atmosphere. The distribution of the dust-laden gas in the intake pipe is freely distributed through several three-way connections, which will lead to uneven flow of dust-laden gas into the ash hopper, resulting in inconsistent use conditions of each bag, and the air flow rate of some bags Large, the impact force on the bag is large, it is easy to cause damage to the bag, and the air intake of some bags is small, and the filtration efficiency of the bag is not used to the maximum. The equal flow air distribution device. Con...
