Embodiment Construction

[0009] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0010] The present invention is a process system for improving boiler flue gas dedusting, desulfurization and mercury removal efficiency and water utilization, which includes the following content: high-efficiency wet dust collector or desulfurization tower (1), flocculation tank (2), sewage pump (3), high-efficiency Sewage treatment and concentrator (4), dehydrator (5), sprinkler (6), chimney (7);

[0011] Its technological process is as follows:

[0012] 1. The boiler flue gas enters the high-efficiency wet dust collector or desulfurization tower (1), and the flue gas after dust removal and desulfurization directly enters the chimney (7) and is discharged up to the standard;

[0013] 2. The dusty and gypsum sewage from the high-efficiency wet dust collector or desulfurization tower (1) enters the flocculation tank (2) enters the high-...

Abstract

The invention relates to a process system for improving dust removal, desulfurization and demercuration efficiency of boiler flue gas. The process system comprises an efficient wet dust collector or a desulfurization tower, a flocculation basin, a sewage pump, an efficient sewage treatment and concentration device, a dewatering machine, a sprayer and a chimney. The efficient sewage treatment and concentration device is utilized to achieve water recycling, and no secondary pollution is produced. The process system for improving dust removal, desulfurization and demercuration efficiency of the boiler flue gas is safe, simple, practical and reliable, so that the original power utilization and operation costs and byproducts are greatly reduced, emission index is reduced, the energy-saving and environmental-protection purposes are achieved, and the process system has very high economic value and has great promotional value.

Description

technical field [0001] The invention belongs to the field of energy, and in particular relates to a process system for improving boiler flue gas dedusting, desulfurization and mercury removal efficiency and water utilization. Background technique [0002] Improving energy utilization efficiency, saving energy and reducing emissions has received more and more attention, and it is also a national key energy policy. In the field of energy, the traditional methods for dust removal, desulfurization, and mercury removal are electrostatic precipitator, limestone desulfurization, and mercury removal. These methods consume a lot of water, generate a large amount of sewage, and have high operating costs. The power system has been looking for new technologies Instead of traditional crafts. Contents of the invention [0003] In order to overcome the problems existing in the above-mentioned prior art, the present invention provides a method of utilizing water to directly pass through ...
