Problems solved by technology

However, the main disadvantage of the traditional wet dedusting device is that the liquid droplets freeze at low temperature. When purifying fine particles in a low-temperature environment, the liquid droplets condense into solid ice particles, and the ice particles fall directly, resulting in a reduction in the probability of collision with fine particles. , the coagulation rate is low, and fine particles cannot be effectively removed. Traditional wet dust removal devices are difficult to apply to low temperature environments

Description

technical field [0001] The invention relates to the technical field of air pollution control, in particular to a fine particle purification system and method suitable for low-temperature environments. Background technique [0002] In recent years, with the continuous expansion of the global industrialization process, a large amount of industrial waste gas and waste have been produced, which has caused great pollution to the environment. With the vigorous advancement of my country's economic transformation, environmental governance, especially air pollution control, has risen to the national strategic level, requiring regional testing to improve atmospheric environmental governance. There are many kinds of pollutants caused to the atmospheric environment, among which fine particle dust is one of the most harmful pollutants. [0003] Fine particulate matter has the characteristics of small particle size, slow settling velocity, long residence time, strong chemical activity an...
