Example Embodiment

[0026] The cooling electrocoagulation device and method of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments, but it is not intended to limit the present invention.

[0027] figure 1 Shown is the boiler flue gas purification system suitable for the cooling electrocoagulation device of the present invention. The purification system consists of a boiler 1, a denitrification reactor 2, an air preheater 3, a cooling electrocoagulation device 4, an electric dust collector 5, Fan 6, desulfurization tower 7, and chimney 8. The cooling electric coagulation device 4 causes the dust particles in the flue gas (that is, the gas to be dusted) to collide and condense with each other, thereby making the dust particles in the flue gas significantly larger, which is more beneficial to the subsequent electrostatic precipitator 5 for dust removal.

Abstract

The invention provides a cooling and electric agglomeration device. The cooling and electric agglomeration device comprises a housing, an ionization assembly and a heat exchange assembly, wherein an inlet and an outlet are formed in the head end and the tail end of the housing respectively, so that a gas needing dust removal is capable of flowing in from the inlet and flowing out from the outlet; the ionization assembly is arranged in the housing and used for electrifying particles in the gas in the housing; and the heat exchange assembly is arranged in the housing and used for cooling the gas in the housing. The cooling and electric agglomeration device provided by the invention is capable of realizing flue gas cooling and dust agglomeration simultaneously, and capable of promoting an agglomeration effect, reducing the specific resistance of dust, reducing an electric field wind speed of a subsequent electric dust remover, increasing the dust removal efficiency of a system, and remarkably improving the comprehensive performance of the agglomeration device.

Description

technical field [0001] The invention belongs to the field of industrial flue gas purification, in particular to a cooling electrocoagulation device and method. Background technique [0002] At present, my country has become one of the areas with the most serious pollution of fine particles in the world. Severe haze weather occurs frequently. PM2.5 has become a hot term in the society. The control of fine particle pollution is unprecedented. "Ambient Air Quality Standard" GB3095- In 2012, PM2.5 restrictions were added, and the emission standards of air pollutants in thermal power, metallurgy and other major polluting fields were comprehensively revised. Key regions and cities also issued stricter local standards accordingly, and particulate matter control entered a refined stage. [0003] The high-efficiency dust removal equipment in the industrial field is mainly divided into two types: electrostatic precipitator and bag filter. The electrostatic precipitator has stable oper...
