Cogeneration unit hot water supply water mixing and temperature equalizing system

Abstract

The invention discloses a cogeneration unit hot water supply water mixing and temperature equalizing system. The system comprises a plurality of heat network head stations, a water mixing and temperature equalizing device and a control unit, wherein a plurality of water inlets and a plurality of water outlets are formed in the water mixing and temperature equalizing device; each heat network headstation communicates with a heat supply water return main pipe, and is used for exchanging heat with heat supply steam to heat return water and convey the return water to the water mixing and temperature equalizing device; and a shell of the water mixing and temperature equalizing device is in a cylindrical shape with a water mixing cavity in the middle part, and is provided with the plurality ofwater inlets and the plurality of water outlets, and the number of the water inlets and the number of the water outlets are the same as the number of the heat network head stations. According to the system, valve banks are arranged on all branch inlet pipelines and branch outlet pipelines, so that the heat network water supply pressure and flow of a water inlet and outlet water mixing device are regulated so as to meet the external heat supply quality; and effective interconnection and mutual backup of all heat supply systems are realized, the heat source backup coefficient of the cogenerationunit is greatly improved, the heat supply safety reliability and operation flexibility of the cogeneration unit are enhanced, and energy conservation and consumption reduction are realized to a certain degree.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of heating network temperature uniformity, and relates to a hot water mixing water temperature uniformity system for a cogeneration unit. [0003] 【Background technique】 [0004] For heating units configured with multiple heating network first stations and multiple heating pipelines, there is no connection between the first stations or heating pipelines. If the steam turbine unit corresponding to a certain first station is out of service for some reason, or the heating steam flow is greatly reduced due to deep peak regulation, the heating quality of this line will drop sharply, which will adversely affect the normal life of residents. [0005] 【Content of invention】 [0006] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a hot water mixed water temperature equalization system for cogeneration units, which can greatly improve the hea...
