Abstract

The invention relates to a synergistic desulfurization wastewater dedusting and defogging device and a dedusting and defogging technology, and belongs to the technical field of wastewater pollution control. In the synergistic desulfurization wastewater dedusting and defogging device, a filter element is mounted inside a high-efficiency cyclone separator; high-efficiency defoggers and a condenser are mounted inside a wet desulfurization tower; a warming section is mounted inside the condenser; the warming section is communicated with a cooling section; the cooling section and a sprinkling device are mounted inside a circulating cooling water system; an exhaust fan is mounted at the top of the circulating cooling water system; a wastewater pump is communicated with the high-efficiency cyclone separator through a desulfurization wastewater pipeline; the wet desulfurization tower is communicated with the high-efficiency cyclone separator through an underflow pipeline; the high-efficiency cyclone separator is communicated with the sprinkling device through an overflowing pipeline; the circulating cooling water system is communicated with a flue evaporation system through a concentratedwastewater pipeline; a backwashing water tank is communicated with the high-efficiency cyclone separator through a backwashing pipeline. Through resource reutilization of desulfurization wastewater, awater resource is saved; through synergistic desulfurization wastewater dedusting and defogging, a new idea is provided for desulfurization wastewater treatment.

Description

technical field [0001] The invention relates to a desulfurization wastewater cooperative dedusting and demisting device and a dedusting and defogging process, belonging to the technical field of wastewater pollution control. Background technique [0002] At present, limestone-gypsum wet desulfurization technology is the most widely used desulfurization process in coal-fired power plants, with a market share of more than 90%. Its high-efficiency desulfurization ability has been widely recognized, but its shortcomings are also very obvious. In addition to the complexity of the process system, The high salt content of desulfurization wastewater makes it difficult to realize recycling, resulting in waste of water resources. The national environmental protection requirements are becoming increasingly strict, and the ultra-low emission transformation work is gradually deepening. 2 , NO X , soot emission limits are getting lower and lower, and PM 2.5 , droplets, SO 3 more and m...
