Alternating electric field fine dust electrocoagulation explosion suppression device and method

Abstract

The invention discloses an alternating electric field fine dust electrocoagulation explosion suppression device and method. The device mainly comprises a shell, high-voltage plates, grounding plates,prickles on the high-voltage plates and the grounding plates, insulating plates, middle plates and a high-voltage AC power supply. The high-voltage plates are connected to the high-voltage AC power supply, the grounding plates are connected to the ground, the high-voltage plates and the grounding plates are alternately distributed with intervals, the plates are equipped with the prickles, the middle plates comprise the high-voltage plates, the grounding plates, the insulating plates between the high-voltage plates and the grounding plates, guiding plates before and behind the middle plates, and a high-pressure ventilation pipe at the ends of the middle plates, and the middle plates are provided with round through holes distributed in a rectangular array. According to the invention, throughfine dust in an electrocoagulation gas-solid double-phase air flow, the particle size of dust can be effectively increased, the explosion is suppressed or the explosion intensity is reduced, the structure is simple, the flow resistance is small, and the improvement of the dust removal and collection efficiency of a subsequent dust collecting device is facilitated at the same time.

Description

technical field [0001] The invention belongs to the technical fields of dust explosion suppression, dust-containing gas purification, etc., and particularly relates to an alternating electric field electrocoagulation and fine dust explosion suppression device, which can reduce the power of dust explosion accidents, improve dust removal and collection efficiency, and purify fine particle pollution. Background technique [0002] A large amount of suspended dust will be generated in the production process of the powder-related industry, forming dusty industrial waste gas. Among them, the dust particles with smaller dust particle diameter, that is, the dust effective diameter, are called fine dust particles, and this part of dust is also the most harmful part. [0003] When a dust explosion accident occurs, under the same dust mass concentration, the maximum explosion pressure and explosion index during the explosion increase with the decrease of the dust particle size, that is, ...

AI Technical Summary

Problems solved by technology

[0005] Existing dust explosion countermeasures such as explosion venting, explosion suppression and explosion isolation measures are to control the explosion range, remove dust in time, reduce dust production and dust points, control dust concentration to reduce explosion losses, and change the nature of the dust itself. Less; at the same time, fine dust is easy to escape and difficult to separate, which is also a shortcoming that is difficult to solve for dusty gas separation equipment in gas-solid two-phase systems such as cyclone separators
