Problems solved by technology

[0005] Another problem easily caused by wet desulfurization is the problem of "chimney rain". Chimney rain is acidic and contains dust, gypsum, limestone and dissolved salts, which brings new environmental problems around the power plant

Embodiment Construction

[0025] The technical problems, technical solutions and implementation effects solved by the present invention will be further described in detail below in conjunction with the accompanying drawings. This description is only used to explain the present invention, not to limit the present invention.

[0026] Such as figure 1 , 2 As shown, the flue gas desulfurized by the wet desulfurization tower enters the dedusting, demisting and water-saving device. The atomization angle is 130°~170°, which is beneficial to the collision and removal between liquid droplets and fine particles. The atomizing nozzle is connected to the water supply equipment through the pipeline. The fine dust and liquid droplets in the flue gas collide strongly with the mist sprayed from the atomizing nozzle, and the water vapor begins to condense and grow on the surface of the dust particles. The impact cooling chamber is spherical or elliptical, with a spherical diameter of 150mm to 1200mm, and an elliptic...

Abstract

A wet-type desulfurization tower desulfurization, dust removal, fog removal, water-saving process and its device, involving the field of waste gas purification, solving the problem of "gypsum rain" in wet desulfurization and the high cost of wet electrostatic dust removal, including impact cooling chamber and condensation chamber and a fine particle filter unit, the upper opening of the impact cooling chamber is connected to the lower opening of the condensation chamber through a throat, and the fine particle filter unit is fixed on the top of the condensation chamber; the impact cooling chamber is close to the lower opening An atomizing nozzle is also provided at the center of the center, and the opening of the atomizing nozzle faces upward. The atomizing nozzle is connected to the external water supply equipment through a pipeline. The invention has the advantages of low cost, simple installation, long service life, no risk of scaling and blockage, and solves the problem of "gypsum rain". The water in the separated flue gas can be recycled to the desulfurization system through the pipeline, and the separated water can be used for desulfurization system, basically realizing zero replenishment of desulfurization system.

Description

technical field [0001] The invention relates to the field of waste gas purification, and specifically designs a wet-type desulfurization tower dedusting and demisting water-saving device, which is suitable for wet desulfurization systems, further dedusting and defogging the saturated flue gas behind the desulfurization tower, and recovering the saturated flue gas. free water and some water vapour. Background technique [0002] my country is a large coal-burning country. The sulfur dioxide, nitrogen oxides and dust produced by coal combustion have caused serious pollution to the atmospheric environment of our country. The flue gas desulfurization, denitrification and dust removal devices have played an important role in improving the atmospheric environment of our country. [0003] At present, my country's denitrification device is mainly based on the SCR process, supplemented by SNCR technology; the dust removal device is mainly based on electrostatic precipitator, bag filte...
