Low temperature evaporation and concentration equipment for semiconductor manufacturing wastewater

Low temperature evaporation and concentration equipment for semiconductor manufacturing wastewater

The low-temperature evaporation and concentration equipment is made of high-quality materials and processes, with corrosion resistance and good mechanical strength. It has a compact structure, simple operation, stable operation, and is not prone to malfunctions. At the same time, the distilled water machine is also equipped with automatic control and safety protection devices, which can monitor the operation in real time and handle abnormalities in a timely manner, ensuring the safe and reliable operation of the equipment. Low temperature evaporation and concentration equipment does not produce secondary pollution when treating wastewater and saltwater. Its efficient distillation process can effectively remove harmful substances and salts from wastewater, obtain a pure water source, and turn wastewater into treasure. The distilled water machine can also be used in conjunction with other equipment to achieve waste heat recovery, further improve energy utilization efficiency, and reduce environmental impact. By using a tubular multi effect distilled water machine, wastewater resource utilization can be achieved, reducing the consumption of natural resources and promoting sustainable development.

Basic principles of low-temperature evaporation technology:

1. Preheating: This step is fully automatic. After the raw water tank reaches the medium liquid level, the water pump runs to generate vacuum, and the evaporator automatically receives water. The compressor runs to generate heat to heat the wastewater in the evaporator tank. In the vacuum state, the wastewater temperature rises to around 30 ℃, and the wastewater begins to evaporate, completing the preheating process.

2. Evaporation and concentration process: The evaporation temperature is set at 35-40 ℃. The compressor compresses the refrigerant to generate heat, and the water evaporates quickly. At the same time, the refrigerant vaporizes through the expansion valve and absorbs heat to cool. The vapor rises and liquefies with the cold liquid into the water storage tank. The refrigerant absorbs heat and compresses it through the compressor to heat up the wastewater. If there are bubbles rising during the evaporation process, the sensor will detect it and automatically add defoaming agent. After one cycle is completed, the concentrated liquid will be discharged (the time of one cycle can be set).

3. Discharge of concentrated solution: After one evaporation cycle is completed, the compression pump stops working, the pneumatic valve of the concentrated solution pipeline opens, the evaporation tank is pressurized, and the concentrated solution is hydraulically injected into the concentration tank.

Equipment features:

1. Low operating costs for compressed air and power supply;

2. Automated, intelligent, and secure treatment of waste liquids;

3. Reduce the cost of waste liquid treatment.

The low-temperature treatment process has been optimized through practical application, consisting of a pre-treatment device, low-temperature evaporation system, and ceramic membrane treatment process for filtration, room temperature evaporation, and membrane filtration (membrane filtration can be selectively added, but the recycled water may contain some micro impurities. For those with low requirements for recycled water, it can be selected according to the actual situation). It can remove heavy metals, salts, and most organic matter, achieving simple reuse. If discharge is required, it is necessary to test the actual water sample and then carry out post-treatment procedures to meet the national discharge standards before discharge.
