Embodiment Construction

[0022] The electrostatic water collection principle of the radial flow electrostatic water collection device of the present invention: a large number of water molecules gather and condense in the air to form white water mist, and after the white water mist enters the high-voltage electrostatic field, a large number of free electrons and charged ions generated by the high-voltage electrostatic field Adsorbed on the fine water droplets, the water droplets gradually grow up and move to the water collecting electrode 8, and are finally captured by the water collecting electrode 8.

[0023] Such as figure 1 As shown, the radial flow electrostatic water collection device of the present invention includes a front discharge net 1, and the rear of the front discharge net 1 is provided with a water collection pole 8 for condensation and electrostatic adsorption of water mist, and the water collection pole 8 adopts porous foam metal or poly Made of parallel corrugated boards or honeycomb...

Abstract

The invention relates to a runoff type electrostatic water collection device which comprises a front discharge net (1), wherein a water collecting electrode (8) for condensation and electrostatic adsorption of water mist is arranged behind the front discharge net (1), the water collecting electrode (8) is formed by porous foam metal or a plurality of corrugated plates, cellular boards or silk screens which are arranged in parallel, the front surface of the water collecting electrode (8) is parallel to the front discharge net (1), and through electric connection with a high-voltage direct-current power supply (3), potential difference is generated between the front discharge net (1) and the water collecting electrode (8). A cooling tower with the runoff type electrostatic water collection device comprises a tower body (10) arranged along the vertical direction, wherein the tower body (10) is internally provided with at least one runoff type electrostatic water collection device. The invention aims at providing the runoff type electrostatic water collection device which has good water mist removal effect, high water recycling efficiency, stable work performance, low running cost, energy conservation and environmental protection properties, and long service life and the cooling tower with the runoff type electrostatic water collection device.

Description

technical field [0001] The invention relates to a radial flow electrostatic water collection device and a cooling tower with the radial flow electrostatic water collection device. Background technique [0002] At present, in the production process of thermal power plants, cooling towers are usually used to cool the circulating water. The water falls in the cooling tower, and the cooling effect is achieved through evaporation and heat transfer. The power plant recycles the recovered water with a lower temperature. The water vapor carried by the hot and humid air discharged from the cooling tower is directly discharged into the atmosphere from the top of the cooling tower, and the water lost in this way is called evaporation loss. For the water vapor mixed in the air, there is no better way to reclaim it at present, which causes a lot of waste. Taking a 2*300MW thermal power plant as an example, its average evaporation loss is 2*486t / h, its total circulation is 2*33800t, evap...
