Method for realizing energy saving and emission reduction by utilizing waste heat in power plant circulating cooling water

Abstract

The invention discloses a method for realizing energy saving and emission reduction by utilizing waste heat in power plant circulating cooling water, belonging to the field of energy saving and environment protection. In the invention, cooling water discharged by a generator extracts heat in a heat pump unit, heats water for warming and then returns to the generator to cool the generator; and the above steps are circulated, the water for warming heated in the heat pump unit provides set warming user radiators by a pipeline and returns to the heat pump unit after being used by the warming user for heating, and the steps are all circulated. The invention not only can warm in winter but also can provide hot water for boilers, thus saving energy.

Description

Technical field: [0001] The invention belongs to the field of energy saving and environmental protection. Background technique: [0002] At present, the generators of thermal power plants discharge a large amount of hot cooling water. The hot cooling water used for cooling directly enters the cooling water tower, and then returns to the generator for cooling cycle after cooling. When the hot cooling water enters the cooling tower, it is A large amount of hot air must be discharged into the atmosphere, which will seriously pollute the environment. At the same time, a large amount of water vapor will be discharged, which will waste water resources virtually. [0003] Taking Jilin Province as an example, the existing installed capacity of thermal power generation is about 6 million kilowatts, and the annual consumption of standard coal is about 4.5 million tons, of which 2.7 million tons of heat are mostly directly discharged into the atmosphere, causing a large amount of heat ...

[0002] At present, the generators of thermal power plants discharge a large amount of hot cooling water. The hot cooling water used for cooling directly enters the cooling water tower, and then returns to the generator for cooling cycle after cooling. When the hot cooling water enters the cooling tower, it is There must be a large amount of hot air discharged into the atmosphere, which will seriously pollute the environment. At the same time, a large amount of water vapor will be discharged, which will waste water resources virtually.

[0003] Taking Jilin Province as an example, the existing installed capacity of thermal power generation is about 6 million kilowatts, and the annual consumption of standard coal is about 4.5 million tons, of which 2.7 million tons of heat are mostly directly discharged into the atmosphere, causing a large amount of heat loss, water loss and environmental pollution.
