Problems solved by technology

The annual regular discharge of the boiler is about 15,000 tons, which directly discharges to the rainwater pipe, causing a large amount of heat loss and also causing environmental pollution and other problems
During the start-up and cleaning process of the boiler, the whole boiler is changed once for cleaning, and the water consumption is as high as 120 tons. If it is directly discharged, a large amount of water resources will be wasted

Abstract

The invention relates to the technical field of boiler blowdown waste heat recovery, and discloses a boiler waste heat, waste steam and waste water recovery system which comprises a periodic blowdown flash tank, a steam exhaust pipe, a water return pipe, a first heat exchanger, a second heat exchanger, a cooling water pipe, a sedimentation tank, a first connecting pipe, a second connecting pipe, a third connecting pipe and a water storage tank. The steam exhaust pipe and the water return pipe are both used for connecting the periodic blowdown flash tank and the second heat exchanger; the first connecting pipe is used for connecting the sedimentation tank and the periodic blowdown flash tank; the second connecting pipe is used for connecting the sedimentation tank and the first heat exchanger; a filter and a conveying pump are arranged on the second connecting pipe; the third connecting pipe is used for connecting the first heat exchanger and the water storage tank; the cooling water pipe is used for connecting the first heat exchanger and the second heat exchanger; the first heat exchanger is provided with a cooling water source connector. The periodic blowdown flash tank is provided with a connector used for receiving boiler waste water and steam. Heat in the boiler wastewater and wastewater are treated and recycled, so that resources are saved and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery from boiler blowdown, in particular to a recovery system for boiler waste heat, steam and waste water. Background technique [0002] During the operation of coal-fired power plant boilers, the evaporation of boiler water is huge, and the boiler water is continuously concentrated with continuous dosing and evaporation of boiler water, and the salt content in boiler water will increase with the evaporation of boiler water. high. In order to ensure the safe operation of the boiler, drainage and blowdown must be carried out. [0003] Boiler drainage is mainly through continuous blowdown expansion and fixed blowdown expansion. The continuous sewage expansion vessel is to expand and separate the sewage of the boiler to obtain steam and waste water. The steam is recovered to the deaerator, and the waste water is discharged into the fixed discharge expansion container. The waste water inclu...
