Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a low-temperature evaporation and concentration device which is easy to clean. Background Art

[0002] With the rapid development of my country's economy and the continuous expansion of industrial development, the environmental pollution caused by wastewater discharge has become increasingly serious. Proper treatment of industrial wastewater is imperative. Low-temperature evaporation and concentration equipment plays a significant role in treating high-salt and high-COD wastewater, which can reduce the cost of industrial wastewater disposal for enterprises. High-salt and high-COD wastewater is stored in raw liquid barrels (ordinary PE barrels are sufficient). After simple pre-filtration, the suspended matter and impurities in the raw liquid are removed. After that, it enters the low-temperature evaporation and concentration equipment to remove salts and COD organic impurities, and discharges reusable distilled water.

[0003] The main function of low-temperature evaporation and concentration equipment is to lower the boiling point of water under the action of vacuum negative pressure, so that the original liquid boils and evaporates at about 37 degrees after heating. The evaporated steam is condensed into liquid water through the condensation system and discharged through the drain tank. Depending on the specific gravity of the water quality, the concentration and reduction rate of water can be as high as about 95%. Through the concentration and reduction treatment of low-temperature evaporation and concentration equipment, the volume of waste becomes smaller, which can greatly reduce the cost of wastewater treatment for enterprises. In addition, the equipment occupies a small area, the base is equipped with rollers for easy movement, and it can be remotely monitored and operated independently. It does not require special care, no external steam source and peripheral cooling water are required, and only electricity and a small amount of compressed air are required.

[0004] However, in actual use, existing equipment is difficult to clean the salt crystals produced by high-salt and high-COD wastewater. At the same time, the large area of ​​salt crystals can easily cause blockage when discharging the device, which is not conducive to the subsequent wastewater treatment of high-salt and high-COD wastewater by the device, thereby reducing the practicality of the device. In view of this, we propose a low-temperature evaporation and concentration device that is easy to clean. Summary of the Invention
