Flue gas automatic equalization distribution device

Abstract

The invention discloses an automatic smoke equilibrium distributing device. The automatic smoke equilibrium distributing device comprises a rotating shaft vertically installed at the smoke bypass position at the outlet end of an air inlet flue. The rotating shaft rotates freely and axially in the air inlet flue through a rotation assembly. A smoke equilibrium distributor is fixed to the body of the rotating shaft. The cross section of the smoke equilibrium distributor is a quadrangle defined by two bilateral symmetry windward sides and two bilateral symmetry leesides, the included angle between the two windward sides ranges from 20 degrees to 60 degrees, and the included angle between the two leesides ranges from 110 degrees to 130 degrees. The automatic smoke equilibrium distributing device has the advantages that smoke in the air inlet flue can be distributed to all cabins in an equilibrium mode so that the smoke flow loads of all the cabins can be equalized, the dust falling efficiency is improved, and the service life of a filter bag is prolonged.

Description

technical field [0001] The invention relates to a flue gas automatic balanced distribution device for a large bag type dust collector. Background technique [0002] The structure of the large-scale bag filter currently used is: including the dust collector box and the air inlet flue with two air outlets distributed on the left and right at the outlet end, and the inside of the dust collector box is divided into two rows by a partition Independently sealed chambers, each chamber is divided into an upper clean air chamber and a lower flue gas chamber by a flower plate, a number of filter bags are vertically hung on the flower plate of each chamber, and the upper air purification chamber of each chamber The chambers are respectively equipped with pulse-jet soot-cleaning mechanisms capable of blowing and cleaning the filter bags, and air inlets are respectively set on the side walls of the lower flue gas chambers of each chamber, and the flue gas in each chamber The air inlets ...

AI Technical Summary

Problems solved by technology

The disadvantage of the above-mentioned large-scale bag filter is that the flue gas flow into each chamber from the air inlet flue is unbalanced, resulting in uneven flue gas flow load in each row of chambers, and the filter bag will be damaged if the long-term load is large. Blockage and damage will reduce the dust removal efficiency and shorten the service life of the filter bag
