Problems solved by technology

Because the packing in the traditional cooling tower is evenly arranged, it is difficult to uniform the heat and mass transfer performance in the tower during use, so that the optimal matching of the air distribution and packing inside the cooling tower cannot be satisfied, and the cooling effect is improved. cooling efficiency of the tower
When spraying nozzles in traditional cooling towers, because the sprayed water covers a small area, the cooling effect of the circulating water is poor and the cooling efficiency is reduced
Traditional cooling towers use manually disassembled glass fiber reinforced plastic windshields. Although they can play the role of windshield, they cannot be adjusted according to the operation mode of the group, which will cause too much cold air to take away the heat of circulating water and reduce cooling. efficiency

Abstract

The invention relates to the field of thermal power generation and energy-saving environment friendliness, and discloses a steam turbine cold source comprehensive optimization energy-saving device. The steam turbine cold source comprehensive optimization energy-saving device comprises a cooling tower, a nozzle used for increasing the diffusion area of spraying water, padding used for improving anair dynamic field in the cooling tower, and a water collecting pond used for water collecting are mounted in the cooling tower in sequence from top to bottom, and an air inlet adjusting device used for adjusting the air inlet amount of an air inlet of the cooling tower is erected on the outer wall of the cooling tower. The diffusion area of the spraying water can be increased, the arranging mannerof the padding can be changed, uniformity and symmetry of the flow field in the cooling tower can be kept, and the aims of optimizing a steam turbine cold source system and reducing power supply coalconsumption rate can be achieved.

Description

technical field [0001] The invention relates to the fields of thermal power generation, energy conservation and environmental protection, in particular to a comprehensive optimization energy-saving device for a cold source of a steam turbine. Background technique [0002] In recent years, with severe competition in the power market and rising coal prices, the economics of thermal power plants have been seriously threatened, and there are huge obstacles to the development of enterprises. How to improve unit performance and reduce coal consumption has always been a long-term task for thermal power companies to continue to study. [0003] The cold source system is one of the essential systems of the power plant. The working status of the condenser, cooling tower and other equipment in the system not only affects the power of the unit, but also affects the output of the turbine, and affects the power consumption of the plant through the power consumption of auxiliary machines. ...
