Description
技术领域technical field
本发明涉及电站锅炉及工业锅炉烟囱烟羽治理技术领域，尤其涉及一种利用电站余热制冷的锅炉湿烟气冷凝收水消雾系统。The invention relates to the technical field of plume treatment of power station boilers and chimneys of industrial boilers, in particular to a boiler wet flue gas condensation water collection and fog elimination system utilizing waste heat from a power station for refrigeration.
背景技术Background technique
根据国家环保要求，电站锅炉或工业锅炉必须对烟气进行脱硫脱硝处理后才能够排放，目前最常用的脱硫方式为湿法烟气脱硫，耗水量大，脱硫后烟气基本为过饱和湿烟气，带有大量水分且易形成白色烟羽，不仅造成视觉污染和环境污染，恶化城市景观，还会加剧雾霾的形成，所以烟气羽雾治理迫在眉睫。同时，电站锅炉或工业锅炉排放的烟气中温度较高，直接排放会造成资源的极大浪费，通常会采用换热器对烟气余热进行回收以提高锅炉效率，做到余热资源的合理利用是提高能源利用率的重要手段。According to the national environmental protection requirements, power plant boilers or industrial boilers must desulfurize and denitrify flue gas before they can be discharged. At present, the most commonly used desulfurization method is wet flue gas desulfurization, which consumes a lot of water. After desulfurization, the flue gas is basically supersaturated wet smoke. The air contains a lot of moisture and is easy to form white smoke plumes, which not only causes visual pollution and environmental pollution, worsens the urban landscape, but also aggravates the formation of smog, so the treatment of smoke plumes is imminent. At the same time, the temperature of the flue gas emitted by power plant boilers or industrial boilers is relatively high, and direct discharge will cause a great waste of resources. Usually, heat exchangers are used to recover the waste heat of the flue gas to improve the efficiency of the boiler and achieve rational utilization of waste heat resources. It is an important means to improve energy efficiency.

The system innovates the structure of the condensing heat exchanger, uses 316L instead of fluorine plastics, titanium alloys, etc., introduces a mechanical ventilation salt water tower and an intelligent control system, reduces the cost and energy consumption of the device and system, and visually eliminates white smoke. The waste heat in the flue gas can remove more than 50% of PM2.5, SO 3 and more than 15% of NO x , taking into account both environmental benefits and economic benefits.
