Description
技术领域technical field
本实用新型属于工业锅炉烟气除尘和余热回收技术领域，具体涉及一种烟气除尘余热回收复合装置。The utility model belongs to the technical field of flue gas dust removal and waste heat recovery of industrial boilers, and in particular relates to a composite device for flue gas dust removal waste heat recovery.
背景技术Background technique
工业锅炉通过燃烧方式将燃料的化学能转化为工质的热能，并将燃烧产物烟气排放如大气环境中。目前工业锅炉已经广泛应用于供暖、电力、煤化工等行业中。Industrial boilers convert the chemical energy of fuel into heat energy of working fluid through combustion, and discharge the combustion product flue gas into the atmosphere. At present, industrial boilers have been widely used in heating, electric power, coal chemical industry and other industries.
为了避免低温腐蚀，工业锅炉的排烟温度往往高于100℃。同时，烟气中还携带有大量微细颗粒物。将这些烟气排放入大气中，不仅会造成空气质量下降，还会浪费大量烟气余热。In order to avoid low-temperature corrosion, the exhaust gas temperature of industrial boilers is often higher than 100 °C. At the same time, the flue gas also carries a large number of fine particles. Discharging these flue gases into the atmosphere will not only cause a decrease in air quality, but also waste a lot of waste heat of the flue gas.
尽管目前大量锅炉已安装有除尘装置，但对排放入大气中的这部分烟气余热基本不予考虑回收利用。然而，我国锅炉排放的烟气量是惊人的，如若对这部分烟气余热加以回收利用，会带来可观的经济效益。Although a large number of boilers have been installed with dust removal devices, the waste heat of the flue gas discharged into the atmosphere is basically not considered for recycling. However, the amount of flue gas emitted by boilers in our country is astonishing. If the waste heat of this part of flue gas is recycled, it will bring considerable economic benefits.
