Stepped electric-to-bag deduster structure

Abstract

The invention discloses a stepped electric-to-bag deduster structure, which comprises an air inlet pipe, a box, an ash bucket and an air outlet pipe. A filter bag is arranged in the box. An upper box and an air purification chamber are successively arranged above the box. The upper box comprises a blowing pipe, an access door and a tube nest. The filter bag is hung on the tube nets. The purification chamber is step-shaped. A settling chamber is arranged at the air inlet pipe. An air-flow separator plate is arranged between the settling chamber and a middle box. The top surface of the air-flow separator plate, the top surface of the settling chamber and the tube nest are positioned at the same height. According to the invention, the original electric deduster structure is fully utilized, the reconstruction period is short, engineering cost is low, and economy is good.

Description

Technical field [0001] The invention relates to a dust remover, in particular to a structure of a stepped electric modified bag dust remover. Background technique [0002] At present, with the strengthening of people’s awareness of environmental protection and further stringent emission standards, electrostatic precipitators are facing severe tests. The standards for industrial kilns and coal-fired boilers require that the emission concentration be reduced to 30mg / m 3 Below and key areas 20mg / m 3 Below: Conventional electrostatic precipitators have been unable to meet environmental protection requirements. In the context of the rapid development of bag dust removal technology, electric modified bag precipitators have become the preferred method for environmental protection upgrades of large dust collectors. In the past transformation, the electrostatic precipitator had to be dismantled, and the transformation period was still relatively long. Especially the original electrostati...

Problems solved by technology

[0002] At present, with the strengthening of people's awareness of environmental protection and the further stringent emission standards, electrostatic precipitators are facing severe challenges. The standards for industrial kilns and coal-fired boilers require that the emission concentration be reduced to 30mg / m 3 Below, key areas 20mg / m 3 The following; Conventional electrostatic precipitators can no longer meet the requirements of environmental protection. Under the background of the rapid development of bag dust removal technology, the electric bag filter has become the preferred method for environmental protection upgrade of large-scale dust collectors.

In the previous transformation, the electrostatic precipitator had to be removed, and the transformation cycle was still relatively long, especially because the site of the original electrostatic precipitator was small, so it was difficult to redesign and install a new bag filter
