Runoff electrostatic water collection device and cooling tower with runoff electrostatic water collection device

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...
