Charged centrifugal mechanical dedusting and defogging device

Abstract

The invention discloses a charged centrifugal mechanical dedusting and defogging device, which is composed of a centrifugal mechanical dedusting structure and an electric dedusting structure. The device has a good dedusting and defogging effect on tail gas of a desulfurization absorption tower.

Description

technical field [0001] The invention relates to a charged centrifugal mechanical dust and mist removal device. Background technique [0002] In recent years, due to the increasing emergence of domestic environmental protection issues, the relevant national environmental protection departments have continued to increase the control and promotion of environmental pollution control, especially air pollution control. Relevant national departments have issued the "Coal Power Energy Conservation and Emission Reduction Upgrading and Transformation Action Plan (2014~2020)", which will push the coal-fired power plant flue gas treatment business to a climax. At present, the domestic smoke emission standard has become the most stringent standard in the world. The plan requires that the chimney particulate matter emission value of coal-fired power plants be lower than 10mg / m3. The release of this standard data is a new topic proposed by the flue gas treatment industry. [0003] The co...

Problems solved by technology

However, the application of wet electrostatic precipitator technology often brings about the problem of generating excess wastewater, which is not within the processing capacity of the original wastewater treatment system of the power plant, causing secondary pollution

In addition, the flue gas flow rate required by the wet electrostatic precipitator system is low. In order to adapt to the low flow rate condition, the system is often built in a large size, which increases the difficulty of construction, operation costs and maintenance.
