Description
Technical Field
The utility model relates to a low energy consumption high efficiency coal fired power plant boiler flue gas desulfurization deNOx systems.
Background
Sulfur dioxide and nitrogen oxides are two major emissions that contribute to atmospheric pollution, and their major hazard to human health and the ecological environment is the formation of acid rain. Once being discharged into the atmosphere, sulfur dioxide and nitrogen oxide can perform complex reaction with water vapor in the atmosphere under the catalysis of sunlight, so that acid rain is formed and falls to the ground, and the method has great harm to human bodies, environment and ecological systems. With the increasing strictness of environmental requirements, the problems of emission of sulfur dioxide and nitrogen oxides are receiving more and more attention. Sulfur dioxide and nitrogen oxides are mainly derived from the combustion process of fossil fuels such as coal, petroleum and the like, and the flue gas emission in the roasting and smelting processes of ores. The smoke discharged by various combustion boilers, particularly boilers in thermal power plants, has the characteristics of low concentration, large smoke quantity, much floating dust and the like, and is difficult to treat. In the traditional technology, the technology for purifying sulfur dioxide and nitrogen oxide in the discharged flue gas is usually to carry out desulfurization and denitration separately, which causes the defects of complexity and bulkiness of a discharged flue gas purification system, large initial investment, high operation cost and the like, and seriously restricts the practical implementation of the desulfurization and denitration of the discharged flue gas; meanwhile, the traditional technology has high energy consumption and low efficiency due to equipment and other reasons.
The desulfurizing tower is tower equipment for carrying out desulfurization treatment on industrial waste gas, and the existing desulfurizing tower has the defects of low dedusting and demisting efficiency and incapability of realizing white smoke elimination. In order to achieve the effect of eliminating white smoke, various methods can be adopted, such as matching with a tube type steam heat exchanger after wet electric precipitation; or a multi-stage heat exchanger is adopted for refrigeration, so that the temperature of the exhaust smoke is lower than a certain value; or heating the flue gas to make the temperature of the flue gas higher than a certain value; or the white smoke can be eliminated by adopting an ion method, a pulse method and the like, but the methods can be realized by means of expensive equipment investment and a large amount of running energy. In addition, the flue gas after desulfurization is further treated by the existing desulfurizing tower usually adopting wet-type electric precipitation or a conventional demister, and the two types of desulfurizing towers can achieve the effects of dedusting and demisting, but have the defects of high investment cost, large occupied area, difficulty in cleaning, easiness in blocking, low dedusting and demisting efficiency and the like. Therefore, it is important to find a desulfurizing tower which is economical and practical, has low investment cost, good white smoke eliminating effect and high dedusting and demisting efficiency.
