Product overview and features:The solution in the natural external circulation evaporator circulates by the density difference of the feed liquid. In order to prevent scaling and crystallization, the heating tube should be operated in a completely submerged state. This evaporator is suitable for the concentration of solutions with less serious fouling and less corrosive. The advantages are simple structure, easy manufacturing and low power consumption. The disadvantage is that the solution circulation speed is slow, not suitable for high viscosity, a large number of crystalline materials, can not be cleaned in situ, the material is heated for too long, not suitable for heat-sensitive materials.
Working principle:External heating type natural circulation evaporator: The liquid is heated in the heating chamber tube, the temperature rises, the density becomes smaller, and the density difference with the cold solution in the circulating pipe causes the liquid to circulate upward in the heating pipe and downward in the circulating pipe. The heated solution enters the evaporation chamber in the form of sensible heat to flash and cool down. Then it goes down into the circulating pipe for circulating heating and evaporation. The circulation speed of the solution in the equipment is not large, generally less than 1 m/s.
