Water recovery system for cooling equipment

Abstract

The invention discloses a water recovery system for cooling equipment, relating to equipment for recovering water vapor in a cooling tower, in particular to equipment for recovering water vapor in cooling towers for use in thermal power plants, large-sized air conditioners and the departments of chemical industry, metallurgy and the like, mainly aiming to solve the problems that great waste is caused since the recovery efficiency of water vapor being over 200 microns in diameter is only 50 percent while water vapor being below 20 microns in diameter is directly discharged into the atmospheric air under the situation that a dehydrator is generally arranged in a cooling tower in the production processes of known thermal power plants and the like and the problem that the manufacturing and running costs are high since air cooling units are adopted in certain power plants. The water recovery system consists of N water-collecting electrodes and corona electrodes which are connected together, wherein the water-collecting electrodes and the corona electrodes are fixed above a dehydrator in a cooling tower through a bracket, and are electrically connected with the anode and cathode of a high-pressure generator respectively. The water recovery system is simple in structure and low in running and manufacturing costs, and the vapor recovery efficiency can be over 95 percent.

Description

technical field [0001] The invention relates to a device for recovering cooling tower water vapor, in particular to an energy-saving and consumption-reducing device for recovering water from cooling tower water vapor in thermal power plants, large-scale air conditioners, chemical industry, metallurgy and other departments. 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 carried by the hot and humid air discharged from the cooling tower, for the water vapor with a diameter of more than 200 microns, it is usually recovered by installing a water eliminator, and its efficiency is only 50%. For the water vapor with a diameter of less than 200 microns, it is directly discharged It is c...

AI Technical Summary

Problems solved by technology

[0003] At present, most thermal power plants in my country do not have an effective recovery method for evaporation loss. Some power plants use air-cooling units and other methods. Only one air-cooling tower is 6 times the cost of conventional towers. The four-season operation consumes a lot of electricity and increases the consumption of coal. volume, so air-cooled methods are expensive to acquire and operate
