The common wet quenching is a quenching mode commonly adopted in the coking industry, and has the advantages of small investment, simple and convenient operation and capability of consuming a large amount of coking wastewater. But has the disadvantages of serious air pollution and waste of a large amount of heat. With the stricter requirements of national energy conservation and environmental protection, the common wet quenching method is gradually replaced by the dry quenching process, and becomes a standby process. For example, since 2012 in the environment-friendly hall of Shandong province, independent coking enterprises approved by the province hall require a dry quenching process to belong to a circular economic project in a park for standby wet quenching. At present, dry quenching units are built in independent coking plants such as Shandong iron and male, Tongling Xinyaxing and the like; the Tangshan City of Hebei province starts to require all coking enterprises to build a dry quenching process in 2015.

Although dry quenching can fully utilize sensible heat of red coke to generate electricity, has considerable economic benefit and can basically eliminate the pollution of quenching to the environment, the one-time energy input is larger, the reconstruction of coking enterprises with short sites is difficult, and a condenser of a dry quenching waste heat power generation system needs a large amount of circulating water, the loss of the circulating water due to evaporation, wind blowing and leakage accounts for 2-3% of the total amount of the circulating water, and the pollution discharge loss is 0.25 times of the loss of the circulating water according to the concentration ratio of 5, so the larger the circulating water is, the larger the consumed new production water is, the larger the pollution discharge is, the larger the supply amount and the discharge amount of the new water are increased, the new water cost and the sewage treatment cost are increased, and meanwhile, the increase of the supply water amount also increases the water quality stabilization treatment cost and the enterprise burden. Therefore, a proper method is required to be found to modify the existing circulating water treatment mode, so that the purposes of saving new water, reducing sewage and reducing the treatment cost of stable water quality are achieved, and meanwhile, the requirements of energy conservation and environmental protection are met.
