Problems solved by technology

[0004] Among the existing technical schemes, many schemes are consistent with the above technical schemes, which cannot break through the removal of fine dust with a particle size of 1 micron to 0.01 micron, and the dust removal efficiency is low; moreover, the exhausted flue gas is mixed unevenly, which easily leads to partial white dust. Smoke is produced, so it is necessary to address these issues

Embodiment 1

[0039] Such as Figure 1 to Figure 3 As shown, the high-efficiency dust removal, desulfurization and white smoke removal device includes a desulfurization tower 1, a circulating water tank 2 and an electrostatic precipitator 3. The circulating water tank 2 is connected to the desulfurization tower 1 through a water pipe, and the circulating water tank 2 is connected to the The desulfurization tower 1 transports water; the input end of the electrostatic precipitator 3 communicates with the output end of the desulfurization tower 1; the desulfurization tower 1 introduces the original flue gas, and desulfurizes and removes the original flue gas; the electrostatic precipitator 3 The flue gas after desulfurization and dust removal is subjected to electrostatic dust removal.

[0040] The desulfurization tower 1 is sequentially arranged with a desulfurization liquid circulation pool, a desulfurization liquid spray layer, a desulfurization demister, a hood partition, a cold water spra...

Embodiment 2

[0056] Such as Figure 1 to Figure 3 As shown, the efficient dust removal, desulfurization and white smoke removal method includes the following steps:

[0057] The circulating water tank 2 delivers water to the desulfurization tower 1; the desulfurization tower 1 introduces the original flue gas, and sprays water with the water flow to desulfurize and remove the dust from the original flue gas; the electrostatic precipitator 3 performs electrostatic dust removal on the desulfurized and dust-removed flue gas, Discharge the flue gas after electrostatic dust removal.

[0058] The desulfurization tower 1 is sequentially arranged with a desulfurization liquid circulation pool, a desulfurization liquid spray layer, a desulfurization demister, a hood partition, a cold water spray layer, and a dust and demister eliminator from bottom to top. The upper end of the desulfurization tower 1 A gas outlet communicating with the inside thereof is provided; a desulfurization circulation pump...

Abstract

The invention relates to an efficient dust collection, desulfuration and white smoke elimination device and method. The efficient dust collection, desulfuration and white smoke elimination method comprises the following steps: conveying water flows to a desulfuration tower from a circulation water tank; introducing a crude flue gas into the desulfuration tower, and spraying water by using the water flow to implement desulfuration and dust collection on the crude flue gas; and performing electrostatic dust collection on the flue gas after desulfuration and dust collection by using an electrostatic dust collection device, and discharging the flue gas after electrostatic dust collection. Compared with a conventional technical scheme, the device and the method are high in dust collection efficiency, and white smoke can be effectively eliminated.

Description

technical field [0001] The invention relates to the technical field of chemical engineering and environmental protection, in particular to a device and method for highly efficient dust removal, desulfurization and white smoke removal. Background technique [0002] The flue gas produced by burning fossil fuels such as coal-fired power plants contains not only a large amount of sulfur dioxide, but also a large amount of fine particles, which will form aerosol pollution at the chimney exhaust outlet, which is one of the important culprits of severe weather such as haze First, to achieve ultra-clean dedusting of flue gas desulfurization has become an urgent task in today's air pollution control industry. [0003] In the prior art, the application number is 201710451922.8, a device and method for ultra-clean dust removal and white smoke removal of desulfurization flue gas, which includes a desulfurization tower, a cooling tower and a circulating water tank, and the circulating ...
