The use of out-tube condensers and water ring vacuum pump structure mixed condenser, cold water tower, water ring vacuum pump with heat pumps, material preheater, mixed condenser, cold water tower and water ring vacuum pump of the triple-effect falling film evaporator, by cooling water pump to the cooling water towers, the cooling water temperature 8 ℃, in the majority of the calculation of evaporator generally take 6 ℃. The pressure of cooling water pumps do not ask for much, as long as the cooling tower circulating water can be sent to the cold water, the course of their work only the cooling water circulating through the use of cold water tower, almost no additional low-temperature water, water-saving effect of special significant, especially in the greater significance of water scarcity areas.

     Multi-effect evaporator supporting the choice of pump is single-face mechanical seal pumps, I have been selected valve plant in Jiangsu Jingjiang fluoroplastics alloy pumps, successfully applied to food industry companies Jilin Songyuan pharmaceutical production of vitamin C, then The main purpose of Vitamin C in order to solve the corrosion resistance of the pump to the special requirements, and later successfully applied to RNJM03-5000-type three-way falling-film evaporator, and Dan Long Group and Bright Dairy companies Hailaer applications, the effect has been好. However, this alloy fluoroplastics only mechanical seal pumps water to remove Office, and supporting the electrical power and little change in the past, the selected pump. Subsequently selected the company Wuxi Pump ICB Jan 9 series single-end stainless steel plate stamping mechanical seal pumps, the same used in RNJM02-2400 type double-effect falling-film evaporator
