Microporous plate dust removal structure on dry desulfurization and denitrification equipment

Abstract

The invention discloses a microporous plate dust removal structure on dry desulfurization and denitrification equipment, which comprises an adsorption tower and a desorption tower, wherein a flue gasinlet is formed in the bottom of the adsorption tower, and a transverse flue gas outlet is formed in the top of the adsorption tower; a front chamber, a middle chamber and a rear chamber are arrangedin the adsorption tower; perforated plates are arranged between the front chamber and the middle chamber as well as between the middle chamber and the rear chamber, and a microporous plate is arrangedbetween the rear chamber and the flue gas outlet; the desorption tower comprises a heating section arranged at the upper part in the desorption tower and a cooling section arranged at the lower partin the desorption tower; the lower end of the adsorption tower is communicated with the upper end of the desorption tower through a desorption tower chain bucket machine for transporting active coke;and the lower end of the desorption tower is communicated with the upper end of the adsorption tower through an adsorption tower chain bucket machine for transporting active coke. The purpose of reducing the equipment cost and the maintenance cost is achieved, and the problem that the occupied area is increased due to the subsequent increase of dust removal equipment is improved.

Description

technical field [0001] The invention belongs to the field of sintering and pellet flue gas treatment, and more particularly relates to a microporous plate dust removal structure on dry desulfurization and denitration equipment. Background technique [0002] Dry desulfurization and denitrification equipment (hereinafter referred to as: DDDS) is a device for processing large volumes of flue gas discharged from sintering machines and pelletizing equipment. DDDS mainly uses activated coke as an adsorbent to absorb harmful substances such as SOx, NOx, dust, heavy metals and dioxins in the flue gas to meet the national emission standards. [0003] However, at present, the export dust content of DDDS equipment is not low enough, and it is necessary to increase the equipment such as bag dust removal in the future, which will increase the investment and the problem of large floor space. SUMMARY OF THE INVENTION [0004] In view of the deficiencies in the prior art, the purpose of ...

AI Technical Summary

Problems solved by technology

[0003] But at present, the dust content of the outlet of DDDS equipment is not low enough, and it is necessary to add equipment such as bag dust removal in the future, which will increase the investment and also have the problem of large area.
