Embodiment

[0027] like Figure 1-3 As shown, a cooling tower circulating water flow measurement device includes: a cooling tower 1, a vertical shaft 2, a water collection tank 3 and a water collection tank 4 are arranged in the cooling tower 1, the vertical shaft 2 is placed in the center of the cooling tower 1, and the water collection tank 3 is There are four triangles, one end of which is connected with the shaft 2, and the other end is connected with the edge of the collecting tank 4. The collecting tank 3 extends from the center of the tower to the edge of the collecting tank 4 with a certain slope (the center of the tower is high, and the edge of the collecting tank is low), The circulating water outlet is made to flow out along the water collecting tank 3, which is convenient for real-time and accurate measurement of the cooling tower outlet water temperature.

[0028] It also includes: the outlet air temperature and air velocity measuring points 5 are arranged at the throat of th...

Abstract

The invention provides a cooling tower circulating water flow measuring device. The cooling tower circulating water flow measuring device comprises a cooling tower; a vertical shaft, a water collecting tank and a water collecting tank are arranged in the cooling tower, and the water collecting tank is connected with the vertical shaft and the water collecting tank; the tower outlet air temperature and air velocity measuring points are arranged at the throat part of the cooling tower; the tower inlet air temperature measuring point is arranged at the periphery of the cooling tower; the atmospheric pressure measuring point is arranged at a position which is at least 50m away from the cooling tower; the tower inlet water temperature measuring point is arranged in the vertical shaft; and the tower outlet water temperature measuring point is arranged at the tail end of the water collecting tank. The circulating water flow of the cooling tower can be accurately obtained, and the circulating water flow of a power plant can be effectively measured and monitored.

Description

technical field [0001] The invention relates to the technical field of cooling tower circulating water flow measurement, in particular to a cooling tower circulating water flow measurement device. Background technique [0002] The cooling tower circulating water flow is a key parameter for the operation of thermal power plants. The circulating water flow is directly related to the cooling tower inlet and outlet water temperature, the condenser end difference, the unit back pressure and the power consumption rate of the power plant. It is of great significance to the operation of the power plant to realize the measurement and monitoring of the circulating water flow in the power plant. [0003] At present, most power plants in China lack the measurement and real-time monitoring of the circulating water flow of the power plant. They mainly test the outlet pressure of the circulating water pump, and then reverse the circulating water flow according to the relationship between t...
