Problems solved by technology

[0004] In view of this, the purpose of one or more embodiments of this specification is to propose a circulating water low-vacuum heating system to solve the problem of reducing the temperature of the circulating water through the heat dissipation of the cooling tower, resulting in waste of heat, and the loss of heat accounts for the input heat of the power plant. About 30% of the total, due to the open heat dissipation method, the loss of water evaporation will also lead to the waste of water resources

Abstract

The invention provides a circulating water low-vacuum heating system which comprises a steam turbine condenser. The output end of the steam turbine condenser is connected with a cooling tower through a cooling conveying pipe, and the input end of the cooling tower is connected with the output end of the steam turbine condenser through the cooling conveying pipe; and the output end of the cooling tower is connected with the input end of the steam turbine condenser through a cooling backflow pipe. According to the circulating water low-vacuum heating system, by adjusting and reducing the vacuum degree of the steam turbine condenser, the exhaust steam temperature of the steam turbine condenser is increased to heat cooling circulating water, the cooling circulating water with the increased temperature can be conveyed to a heat exchanger through the circulating conveying pipe, and the circulating water is further heated through the heat exchanger by means of steam, so that the circulating water is conveyed to a heating pipeline for resident heating, the circulating water is cooled and flows back to the steam turbine condenser after heat dissipation of heating radiators, the steam exhaust temperature of a steam turbine is reduced, and the circulating water heating system is formed to reduce heat and moisture loss.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of power generation and cooling, and in particular to a circulating water low-vacuum heating system. Background technique [0002] The steam turbine generator set is that the superheated steam generated by the boiler enters the steam turbine and expands to do work, so that the blades rotate to drive the generator to generate electricity. In use, the exhaust steam of the steam turbine of the biomass power plant steam turbine is discharged into the atmosphere through the cooling tower, taking away the latent heat of evaporation and reducing the temperature of the circulating water, so as to ensure the vacuum and exhaust temperature of the turbine generator condenser , to ensure the safe and economical operation of the unit. [0003] The applicant found that the method of reducing the temperature of the circulating water through the heat dissipation of the cooling tower causes wa...
