Description

Technical Field

[0001] The utility model relates to the field of wastewater circulating cooling towers, in particular to a water vapor recovery device used for wastewater circulating cooling towers. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to reduce the water temperature. Its cooling is to generate steam by exchanging heat with the air after water flows in contact with it. The steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to reduce the water temperature through an evaporative heat dissipation device to ensure the normal operation of the system. Industrial wastewater includes production wastewater, production sewage and cooling water, which refers to wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with the water. There are many types of industrial wastewater with complex components. For example, electrolytic salt industrial wastewater contains mercury, and heavy metal smelting industrial wastewater contains various metals such as lead and cadmium. Since industrial wastewater often contains a variety of toxic substances, polluting the environment is very harmful to human health. Therefore, according to the composition and concentration of pollutants in the wastewater, corresponding purification measures should be taken for disposal before it can be discharged. In this process, industrial wastewater needs to be cooled.

[0003] For example, a water vapor recovery device for a wastewater circulating cooling tower with publication number CN217585386U can drive the cutting blades to rotate under the action of a cutting motor. As the cutting blades rotate, the water vapor entering the collecting chamber can be cut, and the water vapor will be collected near the cutting blades during the cutting process. As the cutting blades rotate, the water vapor can be pushed to the wall of the collecting barrel. Under the action of the barrel wall of the collecting barrel, the water vapor can exchange heat with the dry and cold air entering through the dry and cold air flow pipe. Under the action of the dry and cold air, the water vapor can be condensed into water droplets, thereby facilitating the recovery of the water vapor. The water vapor condenses into water droplets on the surface of the barrel wall. There is a situation where water droplets hang on the surface of the barrel wall. The water droplets need to wait for a while before sliding down, which reduces the efficiency of water droplet recovery.

[0004] Therefore, it is necessary to provide a water vapor recovery device for a wastewater circulating cooling tower to solve the above technical problems. Utility Model Content
