Enclosed evaporative cooling cold water set mist cooling system for power plant air cooling system

Abstract

The invention discloses an enclosed evaporative cooling cold water set mist cooling system for power plant air cooling system, which comprises an enclosed evaporative cooling cold water set, which is connected to a water storage tank by pipeline, and the water storage tank is connected with a nozzle a by pipeline and spray pipeline; the enclosed evaporative cooling cold water set is connected with a water-feeding pump by a condensation water return pipe a, and the water-feeding pump is connected with a high-pressure heater, a boiler, a superheater and a steam turbine by pipeline, and the steam turbine is connected with a dead steam pipe, and the dead pipe is respectively connected with an air cooling radiator, a condenser and a mixed condenser by the dead steam pipe, and the direct air cooling apparatus is connected with a condensation water return pipe b, a pipeline and a condensation water return pipe a by pipeline. The cooling system of the present invention uses evaporative cooling technology, and combines with air cooling apparatus in thermal power plant, thereby guarantying safe, high efficient and economic operation of the power plant air cooling system during high temperature period with a certain water consumption, and improving generating load of the power plant generating set during high temperature period, and improving power plant generating benefit.

Description

technical field [0001] The invention belongs to the technical field of air conditioning equipment, and relates to a spray cooling system of a closed evaporative cooling water chiller for power plant air cooling, in particular to a closed evaporative cooling water chiller, a direct air cooling device, an indirect cooling device of a surface condenser, a mixing The air-cooled spray cooling system of the power plant combined with the indirect cooling device of type condenser, water storage tank, spray equipment and related circulating water treatment equipment, boiler and steam turbine. Background technique [0002] In the dry area of ​​Northwest my country, there are abundant coal resources, which is why thermal power plants are concentrated in this area, but the lack of water resources in dry areas poses a great test for the condensing system of thermal power plants. For thermal power plants in Northwest my country, it is forbidden to adopt the cooling form of traditional wet...

AI Technical Summary

Problems solved by technology

According to the actual operation effect of the current air cooling device, during the high temperature period in summer, the heat exchange efficiency of the air cooling radiator decreases, the system back pressure increases, and the power generation load decreases, which has caused great troubles to the economic production of the power plant.
