Abstract

The invention provides a flue gas treatment system based on chemical aggregation and electric precipitation. The flue gas treatment system comprises an aggregation liquid preparation unit, an atomization spraying unit and an electric precipitation unit, wherein the aggregation liquid preparation unit comprises an emulsification tank, a preparation tank and a mixing tank, the emulsification tank isprovided with a solid agglomerant inlet, a first water filling nozzle and an emulsion outlet, the preparation tank is provided with a liquid agglomerant inlet, an emulsion inlet, a second water filling nozzle and a liquid mixture outlet, the emulsion inlet communicates with the emulsion outlet, the mixing tank is provided with a liquid mixture inlet, a third water filling nozzle and an aggregation liquid outlet, the liquid mixture inlet communicates with the liquid mixture outlet, and the aggregation liquid outlet is connected with the atomization spraying unit arranged on an inlet flue of the electric precipitation unit through a material conveying pipeline. According to the flue gas treatment system, the chemical aggregation and the electric precipitation unit are combined, so that aggregation liquid is sprayed into the flue, the moisture content of flue gas is increased, fine particles in the flue gas grow up so as to be convenient to remove by the electric precipitation unit, andthe dedusting efficiency and the stability of the flue gas treatment system are greatly increased.

Description

technical field [0001] The invention belongs to the technical field of flue gas treatment, and in particular relates to a flue gas treatment system based on chemical agglomeration and electric dust removal. Background technique [0002] Coal is the main energy source in my country. As of the end of 2016, the total installed capacity of thermal power in the country has reached 1.05 billion kilowatts, accounting for 63.6% of the total installed capacity of electric power. The pattern will not change. However, the flue gas emitted by coal-fired power plants is an important emission source of various pollutants in the atmosphere in my country, and more than half of SO 2 , NOx and inhalable particulate matter originate from coal-fired power plants. In addition, various types of wastewater generated by power plants, such as desulfurization wastewater, are still relatively prominent. With the continuous improvement of people's awareness of environmental protection, the environment...
