Municipal solid waste incineration power generation low temperature circulating water heat supply system

Abstract

The invention relates to the technical field of municipal solid waste treatment clean energy, in particular to a municipal solid waste incineration power generation low temperature circulating water heat supply system. The municipal solid waste incineration power generation low temperature circulating water heat supply system is provided with a steam turbine, a condenser, an electric generator anda cooling tower and is characterized in that the cooling tower is connected with a water outlet pipe of a heat consumer heating system by a water inlet mother pipe and a water inlet pipe of the heatconsumer heating system is connected with the cooling tower by a water returning mother pipe; the water inlet mother pipe and the water returning mother pipe between the cooling tower and the heat consumer heating system are connected with a condenser cooling pipeline system; the condenser cooling pipeline system consists of a first side water inlet pipeline, a first side water outlet pipeline, asecond side water inlet pipeline and a second side water outlet pipeline; and a peak heating system is arranged on the water returning mother pipe between the condenser cooling pipeline system and theheat consumer heating system. The system has the advantages of energy conservation, green and environmental protection, no pollution, no land occupation, emission reduction and the like.

Description

technical field [0001] The invention relates to the technical field of domestic waste treatment and environmental protection energy, in particular to a low-temperature circulating water heating system for domestic waste incineration, power generation, energy saving, environmental protection, no pollution, no land occupation, energy saving and emission reduction. Background technique [0002] As we all know, in the northern part of my country, some coal-fired power generation enterprises use the heat released when the exhaust steam condenses in the low-vacuum operation of the condensing steam turbine unit to supply heat to the outside. Increase, that is, reduce the vacuum degree of the condenser, increase the temperature of the cooling water, change the condenser to the heating network heater of the heating system, and the cooling water is directly used as the circulating water of the heating network, so this heating method is called Provide vacuum heating for condensing units,...

AI Technical Summary

Problems solved by technology

At present, most domestic waste incineration power plants use extraction condensing turbogenerators. During the heat exchange process of the units, the heat that is brought to the cooling tower by the circulating water and discharged into the atmosphere accounts for about 73% of the total energy, forming a "cold source". "loss", resulting in a serious waste of energy, and in the actual heating process, generally from December to February of the next year is the cold season, at this time the heating needs to be sufficient, in November and the next year In March and April, there is generally no need for sufficient heating, which involves the problem of energy waste
