Embodiment Construction

[0022] Such as figure 1 , 2 , 3, 4, 5, 6, 7, 8, 9, 10, 11, the cooling tower circulating water temperature reduction device of the present invention is fixed on the frame beam 3 of the original fixed sprinkler pipe, and the cooling tower circulating water temperature reduction device covers the entire cooling tower In the cross section of the tower, there are N cathode frames 4 on the frame beam 3, and N cathode frames 4 are at least one. On the cathode frame 4, there are N parallel cathode needles 8, the cathode frame 4 and the cathode. The needle 8 is a conductive body. On the outside of each cathode needle 8 is provided an anode plate 7 parallel to the cathode needle 8. The cathode needle 8 penetrates the space of the anode plate 7, and the cathode frame 4 is fixed on the cross section of the anode plate 7. Below, the cross-sectional channel shape of the anode plate 7 can be hexagonal, such as figure 1 , 3 As shown, it can also be a quadrilateral, such as Figure 4 Shown, or ...

Abstract

The invention relates to a device for reducing the temperature of circulation water of a cooling tower to mainly solve the problems that according to an existing power plant cooling tower, the temperature of circulation water is high, water consumption is large, the cost of an air cooling unit is high, maintaining is not convenient, and running cost is high. N cathode frames are arranged above a frame girder in the cooling tower, N parallel cathode needles are fixedly arranged on the cathode frames in the vertical direction, the outer side of each cathode needle is provided with an anode plate parallel to the cathode needle, the cathode frames are fixed to the lower portions of the sections of the anode plates, and the anode plates are fixed to the frame girder through a supporting frame and an insulator below the supporting frame. A direct current is exerted between two electrodes, wind energy is produced through convection of electric ions between the two electrodes, the contact area between the high enthalpy water and the low enthalpy cold air in the tower can be increased, the temperature of circulation water falling into a water collecting pool below the tower can be reduced, the temperature of circulation water can be reduced by 1-5 DEG C, and the evaporation capacity of circulation water is reduced by 80 percent. The device is low in production cost and easy to install.

Description

Technical field [0001] The invention relates to a device for reducing the circulating water temperature of a cooling tower while reducing the evaporation of circulating water, in particular to a device for reducing the circulating water temperature of the cooling tower and reducing the evaporation of circulating water in power plants, chemical industry, metallurgy, large air-conditioning and other departments Energy saving and consumption reduction equipment. Background technique [0002] At present, in the production process of thermal power plants, the cooling tower is a device that uses the contact of water and air to dissipate the waste heat generated in the heat exchange in the condenser through evaporation. The temperature of the circulating water in the condenser is an important indicator to ensure a good vacuum in the condenser of the power plant and reduce the energy consumption of the unit. The circulating water temperature is reduced by 1℃, the condenser vacuum is incr...
