Method and device for collecting heat dissipation water vapor at top of thermal power plant circulating water cooling tower

Abstract

A device for collecting heat dissipation water vapor at the top of a thermal power plant circulating water cooling tower is disclosed. The cooling tower is a hyperbolic cooling tower, a cold water pool is arranged at the bottom of the cooling tower, the cold water pool comprises a collecting cover, a flow guiding trough, four drainage pipes, a rigid ring and a plurality of axial flow fans, the collecting cover is an annular cover body, the annular side face of the collecting cover is in a certain radian, the collecting cover is located at the top of the cooling tower, and the flow guiding trough is an annular trough; and the annular body surrounds the upper portion of the cooling tower and is located at the bottom of the collecting cover to be integrally connected with the collecting cover, the four drainage pipes are located on the side wall of the cooling tower, one end of each drainage pipe communicates with the flow guiding trough, and the other end of each drainage pipe is connected with the cold water pool. A method for collecting the heat dissipation water vapor at the top of the thermal power plant circulating water cooling tower by using the device comprises four steps, the device and the method can effectively collect the heat dissipation water vapor at the top of the cooling tower, the repeated water-using rate of the thermal power plant is increased, the consumptionamount of the thermal power plant circulating cooling water is reduced, and a decisive effect on water saving of the thermal power plant is achieved.

Description

technical field [0001] The invention belongs to the technical field of water treatment in thermal power plants, and in particular relates to a method and a device for collecting heat-dissipating water vapor at the top of a circulating water cooling tower of a thermal power plant. Background technique [0002] In recent years, my country is a country with very poor water resources, especially in inland water-scarce areas, water resources have become the main factor restricting its economic development. Thermal power plants are large water consumers. A 6×350MW thermal power plant consumes about 8×104m3 of water per day, which is equivalent to the daily domestic water consumption of residents in a small and medium-sized city. The shortage of water resources will limit the operation of thermal power plants. It may even affect the development of other industries or sectors. [0003] In the various processes of thermal power plants, there are usually a lot of mist clusters releas...

Problems solved by technology

[0003] In the various processes of thermal power plants, there are usually a lot of mist clusters released in the air at the top of the cooling tower, resulting in a waste of water resources. How to collect the heat-dissipated water vapor at the top of the cooling tower for secondary recycling has become an urgent problem to be solved.
