Cooling Tower Saturated Water Vapor Recovery Device and Water Saving System Using It

Abstract

The invention discloses a cooling tower saturated steam recovery device and a water saving system applying the same. The recovery device comprises a cooling tower body; a conical cap-shaped steam recovery device fully covers the top of the cooling tower body; the steam recovery device includes multiple refrigerant water pipes communicated in multiple directions, and multiple steam recovery units transversely arranged between the refrigerant water pipes closely; the refrigerant water pipes and the steam recovery units are communicated with each other; a refrigerant medium is filled in a cavity; a workshop heat exchange system of the water saving system is connected with the recovery device; a recovery pool is arranged below the recovery device, and is connected with the workshop heat exchange system; a water quality purifier is arranged between the recovery pool and the workshop heat exchange system; and the recovery pool is connected with a water quality stabilizer feeding device. The cooling tower steam recycling rate is higher than 85%, and all steam can be nearly recovered, so tat the emission rate is largely reduced, the water resource utilization rate is increased, and the cost investment is reduced.

Description

technical field [0001] The invention relates to the technical field of saturated water vapor recovery, in particular to a cooling tower saturated water vapor recovery device and a water-saving system using the same. Background technique [0002] According to monitoring, groundwater in most cities across the country is currently subject to point and surface pollution to a certain extent, and there is a trend of increasing year by year. The increasingly serious water pollution not only reduces the use function of water bodies, but further exacerbates the contradiction of water resource shortage, which has a serious impact on the sustainable development strategy being implemented in my country, and also seriously threatens the drinking water safety of urban residents and the people. health. The Ministry of Water Resources predicts that China's population will reach 1.6 billion in 2030, and the per capita water resources will only be 1,750 cubic meters by then. With full consid...

Problems solved by technology

[0005] The heat transfer of cooling towers depends on heat conduction and mass transfer. Mass transfer means that the evaporation of water transfers heat from water to air, and then is taken out of the tower by steam. According to different temperatures, the evaporation is 1.064% to 1.80% of the circulating water, which accounts for 80% of the water supply, calculated on the basis of 25000t / h circulation, the daily evaporation is 6384 tons, causing most of the waste of circulating water
