Air flow uniform distribution device for electric dust remover

Abstract

The invention provides an air flow uniform distribution device for an electric dust remover. The device comprises a flow guide grating, hanging plates, bolt components, flow equalizing plates and triangular flow guide plates, wherein the periphery of the flow guide grating is welded on an inlet smoke box and fixed; the hanging plates are welded on an upper sealing plate of the inlet smoke box and fixed; the flow equalizing plates are fixed on the hanging plates through bolts and nuts; two sides of each flow equalizing plate are welded and fixed with side sealing plates of the inlet smoke box; the triangular flow guide plates are hung in holes of the flow equalizing plates; the hanging plates are welded and fixed with the flow equalizing plates after being bent; and after flue gas enters the inlet smoke box, air flow is uniformly divided by the flow guide grating, the flue gas enters the first layer of flow equalizing plate and the second layer of flow equalizing plate to be diffused and uniformly distributed, the flow in an area with high flue gas flow velocity is locally choked by the triangular flow guide plates, and the part of flue gas is choked and distributed, so that an ideal uniform distribution effect of the flue gas entering an electric field is achieved. By the device, resistance caused by a plurality of layers of flow choking plates previously is reduced, the operating cost of the electric dust remover is reduced, the whole steel consumption is reduced, and investment cost is saved.

Description

technical field [0001] The invention relates to an electric dust collector, in particular to an airflow uniform distribution device thereof. Background technique [0002] With the improvement of national flue gas emission standards, the requirements for dust removal efficiency of various dust collectors are becoming more and more stringent. Among them, the uniformity of airflow distribution at the inlet of electrostatic precipitators is the key to improving dust removal efficiency. Conventional electrostatic precipitator inlet airflow uniform distribution method simply adopts the blocking method. This method not only increases the running resistance and steel consumption of the dust collector, but it is difficult to ensure the uniform airflow distribution effect and improve the dust removal efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is that, aiming at the deficiencies of the prior art, a device for uniform air...

Problems solved by technology

Conventional electrostatic precipitator inlet air flow is evenly distributed in the way of simply blocking flow, which not only increases the running resistance and steel consumption of the dust collector, but it is difficult to ensure the uniform air flow effect and improve the dust removal efficiency.
