Two-stage cooling, what does it mean? Two-stage cooling, heating sterilization process: 1-coarse filter 2-compressor 3-storage tank 4,6-cooler 5-cyclone separator 7-screen separator 8-heater 9-filterThe characteristic of this process is that the air is cooled twice, the oil and water are separated twice, and then filtered after proper heating. The advantage of two cooling and separation is that it can improve the heat transfer coefficient, save the cooling water, and the separation of oil and water is relatively complete. After the first cooling of the condenser 4, most of the oil and water are condensed into droplets, and the fog drops and the concentration is high, so it is suitable to be separated by a cyclone separator. The droplets condensed for the second time are small and small, and can only be captured by a screen separator. Groundwater or ice water can be used for cooling, cooling below 35 °c for the first time, and cooling to about 20 °c for the second stage. In this way, after removing oil and
Where can a company in Hunan do River water purification equipment? can the river water filtered by river water purification equipment be used as drinking water and breeding water? River water filtration equipment can be basically done in Changsha's water treatment equipment company,However, we must examine the qualifications and experience of the other party,This is very important for the effect and maintenance of the later equipment.1. quartz sand filter.The raw water is sent to the quartz sand filter through the slurry pump to remove the sediment, rust, large particles, suspended substances, algae and other harmful substances in the water.2. activated carbon filter.The adsorption capacity of activated carbon is relatively strong.Activated carbon can absorb residual chlorine and odor in water, which shows the importance of activated carbon filter.3. water softener.The hardness of well water is relatively large. after the treatment of the water softener, the hardness of the water can be reduced, the ca
