All-day and self-adaptation air inlet guiding system for thermal power plant cooling tower

Abstract

The invention relates to an all-day and self-adaptation air inlet guiding system for a thermal power plant cooling tower. The system comprises an environment parameter monitoring device and a plurality of guiding devices arranged at an air inlet in the lower portion of a tower body of a cooling tower. The guiding devices are evenly distributed in the peripheral direction at the lower portion of the tower body. The guiding devices comprise guiding plates, guide rails fixedly arranged at the air inlet, positioning sleeves fixed to the lower portions of the guiding plates, rotating shafts connected with the positioning sleeves in a pivoted mode, and bolts fixed to the tops of the guiding plates. The guide rails are circular arc guide rails. When the guiding plates rotate, the bolts slide on the guide rails along guide grooves relatively. Gaskets are arranged between the bolts and the guide rails. The guide rails and the positioning sleeves are all fixed to the tower body. The positioning sleeves are in transmission connection with the environment parameter monitoring device. Compared with the prior art, the all-day and self-adaptation air inlet guiding system for the thermal power plant cooling tower has the advantages that an air inlet guiding flow field is controllable, the structure is simple and firm, and the heat exchanging efficiency is high.

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...

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
