Forced ventilation cooling direct current water taking and draining system

Abstract

The invention relates to the technical field of cooling of power generation equipment, and discloses a forced ventilation cooling direct flow water taking and draining system which comprises a water taking device, a water supply device, a heat exchange device, a cooling tower and a water draining device which are sequentially connected, a water taking opening of the water taking device is connected to a water source, and a water draining opening of the water draining device is connected to the water source. The cooling tower is a mechanical ventilation type cooling tower. According to the system, water is taken from the natural water body to serve as a cooling medium, warm discharged water is discharged into the natural water body, and the cooling tower is arranged and is set to be the mechanical ventilation type cooling tower, so that the warm discharged water subjected to heat exchange treatment through the heat exchange device and heated enters the mechanical ventilation type cooling tower to be further cooled; the temperature of the cooling water can be reduced by the warm discharged water discharged by the cooling tower, and the warm discharged water cooled again is discharged into a water source, so that the discharged warm discharged water can meet the environmental protection requirement, the thermal pollution of the warm discharged water to the water body is effectively avoided, and the ecological environment of aquatic organisms is protected.

Description

Technical field [0001] The present invention relates to the field of cooling technology of power generation equipment, and more particularly to a DC taking drainage system for forced ventilation cooling. Background technique [0002] At present, there is a total of 46% of the boiler to the steam turbine to the steam turbine, and the remaining 54% heat is taken away from the water or atmosphere by the cooling system. If the generator set uses a DC cooling system, the waste heat will follow the temperature drain into the natural water environment, and then release it into the atmosphere; if the generator set uses a circulating cooling system, the waste heat is directly released into the atmospheric environment. DC cooling system is low, the unit operates low, high efficiency, and the cooling capacity is limited due to the cooling capacity of the cooling facility, and the cooling water is high, the unit operates high and low efficiency. [0003] Generally, the factory is on the verg...
