Find External Heating Evaporator Price, Natural External Heating Evaporator, New Circulation External Heating Evaporator on Industry Directory, Reliable Manufacturer/Supplier/Factory from China.
The natural circulation external heating evaporator consists of a tube heater, an evaporating chamber and a circulating tube. If crystallization occurs during evaporation, a liquid-solid separator should be added at the lower mouth of the circulating pipe. The circulating speed of the feed liquid in the evaporator is less than 1m/s. The power is the severe difference between the liquid in the circulating pipe and the heating pipe. The heat transfer area is often hundreds or even thousands of square meters. An evaporation chamber can be equipped with 1-4 heating chambers. Heating tube is longer, its length to diameter ratio L/ D =60-110, the total heat transfer coefficient of 1400-3500W/(㎡*K). The disadvantage of this equipment is liquid column of feed liquid in the tube is higher so boiling point of lower liquid is correspondingly increased caused greater temperature difference, which limits the multi-effect use
With an amount of concentration cycles set using the one-touch counter, concentration of the solution is automatically repeated until the correct value is obtained. Maintenance is very easy due to the simple structure.
■Wide variety of sizes
The volume of evaporation is standardized from 50L/H to 2,000L/H.
