Coal-fired power plant ultralow discharger with independent support structure

Abstract

The invention discloses a coal-fired power plant ultralow discharger with an independent support structure. The coal-fired power plant ultralow discharger comprises an indirect cooling tower, a support frame arranged in the indirect cooling tower, a desulfurization absorption tower, a deduster and a smoke discharger, wherein the desulfurization absorption tower, deduster and smoke discharger are sequentially distributed from bottom to top; a smoke outlet of the desulfurization absorption tower communicates with a smoke inlet of the deduster; a smoke outlet of the deduster communicates with an inlet of the smoke discharger; and the desulfurization absorption tower is vertically arranged on the bottom of the indirect cooling tower. The coal-fired power plant ultralow discharger has the advantages of small occupied area, small flue resistance and low energy consumption.

Description

Technical field [0001] The invention belongs to the technical field of ultra-low emission of coal-fired power plants, and relates to an ultra-low emission device of coal-fired power plants with an independent supporting structure. Background technique [0002] As the air pollution problem has become increasingly severe in recent years, the national and local government departments have issued more stringent pollutant emission limit standards, requiring the smoke and dust emission concentration to not exceed 5mg / m 3 It is generally considered to install a wet electrostatic precipitator device after desulfurization to further remove particulate matter, acid mist and heavy metals in the flue gas to meet the requirements of ultra-low emission standards. [0003] For conventional coal-fired power plants, chimneys, cooling towers, desulfurization towers, and wet electrostatic precipitators are separately arranged, which brings about problems such as high initial investment, large footprin...

AI Technical Summary

Problems solved by technology

[0005] For some power plants, due to the compact layout of the equipment in the intercooling tower, it is difficult to arrange the wet electrostatic precipitator in the intercooling tower, so the wet electrostatic precipitator can only be arranged outside the tower, which will increase the occupied area and reduce energy consumption. Increase and other issues

In the four towers in one arrangement that has appeared so far, the desulfurization tower, wet electrostatic precipitator, flue, and smoke exhaust device are all arranged independently, and there are still problems such as large floor space, large flue resistance, and high energy consumption.
