An all-weather self-adaptive cooling tower inlet air guide system for thermal power plants

Abstract

The invention relates to an all-weather self-adaptive cooling tower air intake guide system of a thermal power plant. The system includes an environmental parameter monitoring device and a plurality of guide devices arranged at the air inlet at the lower part of the tower body of the cooling tower. The guide The devices are evenly distributed in the circumferential direction at the lower part of the tower body, including deflectors, guide rails fixed at the air inlet, positioning sleeves fixed at the lower part of the deflectors, rotating shafts pivoted with the positioning sleeves, and fixed at the top of the deflectors. Bolt, the guide rail is an arc-shaped guide rail, when the deflector rotates, the bolt slides relatively along the guide groove on the guide rail, there is also a gasket between the bolt and the guide rail, the guide rail and The positioning sleeves are all fixed on the tower body, and the positioning sleeves are connected with the environmental parameter monitoring device through transmission. Compared with the prior art, the invention has the advantages of controllable air inlet diversion flow field, simple and stable structure, high heat exchange efficiency and the like.

Description

technical field [0001] The invention relates to the field of optimization of air inlet diversion and air distribution of a natural ventilation counterflow wet cooling tower, in particular to an all-weather self-adaptive air inlet diversion system for a thermal power plant cooling tower. Background technique [0002] At present, domestic thermal power plants usually adopt two methods of cooling circulating water, open and closed. The former uses circulating water pumps to extract a large amount of natural water from rivers, rivers, lakes, and seas, absorbs the waste heat in the circulating water in the heat exchanger to cool it, and then discharges the waste heat into rivers, rivers, lakes, and seas. Circulation has high requirements on geographical location, and sufficient water supply must be ensured nearby. At the same time, when the circulating water is discharged into the natural environment, it carries a large amount of waste heat, and the water temperature is high, wh...

AI Technical Summary

Problems solved by technology

At present, due to changes in environmental factors, the operating condition of the cooling tower is poor, the cooling performance is reduced, and the operation is unstable, which directly affects the cooling efficiency of the circulating water, resulting in an increase in the temperature of the circulating water flowing out of the cooling tower, and the circulating cooling water with a higher temperature After entering the condenser, the vacuum degree decreases, which in turn affects the working efficiency of the steam turbine, the output of the equipment decreases, and the coal consumption of the thermal power plant increases, which affects the economical and stable operation of the thermal power plant

At present, there is no effective way to make the cooling tower maintain the original cooling efficiency of the cooling tower when the environmental parameters change beyond a certain range
