Description

technical field [0001] The invention relates to the field of industrial wastewater treatment equipment. Background technique [0002] In the production process of chemical, electric power, petroleum, pharmaceutical and metallurgical industries, a large amount of concentrated brine is discharged, mainly including reverse osmosis concentrated brine, circulating cooling system sewage and boiler sewage. This type of wastewater contains a large amount of dissolved inorganic salts , the salinity can be as high as tens of grams per liter. If such wastewater is directly discharged into the receiving water body (river, river, lake or sea, etc.), it will break the balance of the receiving water body and cause serious damage to the biological environment in the receiving water body. Destruction threatens the survival of animals and plants in the water. [0003] At present, the commonly used concentrated brine treatment processes include multi-effect evaporation, electrodialysis and re...

AI Technical Summary

Problems solved by technology

[0003] At present, the commonly used concentrated brine treatment processes include multi-effect evaporation, electrodialysis and reverse osmosis, etc. These treatment processes not only have the disadvantages of large equipment investment, high treatment cost and poor economy, but also the high-concentration brine produced cannot be effectively disposed of. The use of direct evaporation not only causes high energy consumption, but also is easy to scale, resulting in waste of resources and other shortcomings

[0004] In the prior art, the high-dispersion method is used to treat the concentrated brine, and the solution is highly dispersed through the high-dispersion equipment, so that the solution forms extremely fine liquid particles of different sizes and forms a highly dispersed mist with the gas. The lower the ratio, the water vapor is more likely to overflow, and the concentration of concentrated brine is reduced to achieve the treatment of industrial wastewater, but the following problems exist in the prior art: high dispersion is a heat-absorbing process, such as the temperature of the high dispersion chamber is not high enough , leading to insufficient vapor pressure of the liquid, so that a large amount of water vapor cannot be formed, which affects the efficiency of liquid dispersion into water vapor, and then the dehydration efficiency of concentrated brine decreases, and the effect of concentrating concentrated brine is poor
