Abstract

The invention belongs to the technical field of cyclic recycling and utilization of power station water treatment and resource energy sources and particularly relates to a concentration and crystallization treatment system and method of blow-down water of a boiler drum. The system is composed of a steam drum, a blow-down control valve, a booster pump, a reactor water inlet control valve, a supercritical water separation reactor, a heater, a decompression valve I, a salt discharging control valve, a decompression valve II and a salt collection device. With the adoption of the concentration and crystallization treatment system and method, under the condition that any catalyst is not added, the separation of salt and water is realized; and meanwhile, the cyclic recycling of the blow-down water and the recycling of the energy are realized, and a novel green, pollution-free and efficient method is provided for treating the continuous blow-down water of a steam boiler.

Description

technical field

[0001] The invention belongs to the technical field of power station water treatment and resource energy recycling and utilization, and in particular relates to a concentrated crystallization treatment system and method for boiler steam drum sewage. Background technique

[0002] At present, with the growth of my country's population and the acceleration of urbanization, the utilization of water resources has basically approached its supply, and the phenomenon of water crisis has become increasingly apparent. Coupled with the continuous increase of people's domestic and industrial water consumption, the supply of water resources is unsustainable, and the pollution of the water environment is getting worse. Only by developing the circular economy of water resources and realizing the recycling of waste water can we truly protect the water environment and reduce water pollution.

[0003] The continuous blowdown of boilers is not only large in quantity, but also ...
