Abstract

The invention discloses a double-working medium indirect air cooling system and a control method thereof, and belongs to the field of indirect air cooling systems of thermal power plant host machinesor auxiliary machines. The double-working medium indirect air cooling system is characterized in that a pump is arranged on a water outlet pipe of a desalted water storage tank, a pump is arranged ona water outlet pipe of an anti-freezing solution water storage tank, the water outlet pipe of the desalted water storage tank is connected with the down stream of a water inlet pipeline of working equipment, the water outlet pipe of the anti-freezing solution water storage tank is connected with the upper stream of the water inlet pipeline of the working equipment, and a switching valve is arranged between the down stream and upper stream of the water inlet pipeline of the anti-freezing solution water storage tank; a water outlet pipeline of the working equipment is connected with a water inlet pipeline of a radiator, a first water outlet pipeline of the radiator is connected with the water inlet pipeline of the working equipment, a second water outlet pipeline of the radiator is connectedwith a water return pipeline of the desalted water storage tank and a water return pipeline of the anti-freezing solution water storage tank, a water return valve is arranged on a water return pipeline of the desalted water storage tank, and a water return valve is arranged on the anti-freezing solution water storage tank; and each pipeline is provided with one valve. According to the double-working medium indirect air cooling system and the control method thereof, the anti-freezing effect during severe cold weather and the cooling effect during scorching hot weather can be met.

Description

technical field [0001] The invention belongs to the field of indirect air-cooling systems for main engines or auxiliary machines in thermal power plants, in particular to a duplex indirect air-cooling system and a control method thereof. Background technique [0002] The indirect air cooling system is an existing mainstream cooling method, which greatly reduces water consumption and effectively saves water resources. But antifreeze is a major problem faced in actual operation at present. When the indirect air cooling system operates at a low temperature, the heat exchange area of ​​the radiator is large and the heat storage capacity of the water-air heat exchanger (cooling triangle) is relatively small, and the temperature of the circulating water in the finned tube of the radiator is affected by the temperature. Dropping, dropping to 0°C or below will cause freezing in the radiator tubes, the light ones will reduce the heat transfer performance, and the severe ones will bl...
