Equipment features：
A、The equipment has high-efficiency defoaming characteristics: the principle is to change the speed and direction of the two steam separator, beginning in two, the gas steam entrainment and droplet impact to the demister on the wall, after collecting under the action of gravity flow back to the separator, the defoaming efficiency can be as high as 99.5% ~ 99.8%, the device can effectively solve the foam liquid entrainment phenomenon, but also greatly reduces the evaporation of condensed water containing low boiling point organic matter (COD) volume, to extend the service life of the equipment, ensure the normal operation of equipment. (Note: no effect on a large amount of foamed material)
B、The equipment can effectively prevent the characteristics of the heat exchange tube scaling: the principle is embodied into separate mold in the vapor liquid solid three-phase separation, in the crystallizer, two times two times through the steam pipe steam discharge, the supersaturated solution of thermal crystallization, under the action of gravity, the solid-liquid phase rapidly separation, emulsion and crystal does not enter the heater, avoid friction and see the problem of tube scaling of heater and crystal and heating wall tube.
C、The equipment has the characteristics of heat transfer enhancement: principle is a forced circulation device is provided with a heating pipe, the material flow rate reaches more than 1.5m/s above (Reynolds number Re> 4000 for the turbulence formation and movement occurred in the turbulent vortex flow vortices will strengthen the relative motion of the fluid inside) to strengthen heat transfer at the same time, the heat transfer efficiency is improved by maintaining high-speed flow of liquid in the bundle (vortex), but also to prevent the material in the heating pipe inner wall of sets, and to maximize prevent the occurrence of fouling. (of high calcium magnesium, silicon ions, the solution is not much)
D、Characteristic of the equipment is stable, safe and easy to operate: the principle is by means of steam control device, controlling the steam flow and pressure, while the configuration of the liquid level automatic control device, which realizes the stable and safe operation of the equipment.
Equipment component：
A、It consists of one or two and three effect evaporators, one or two and three effect separating crystallizer, condenser and so on.
B、The mold is a unique design, can meet the continuous feeding and continuous discharge process requirements, forced circulation evaporator form the best fit, the internal structure of the crystal and the supernatant obtained fast effective separation.
C、The whole process is under the condition of vacuum evaporation, the temperature is relatively low, evaporation evaporation speed, low energy consumption, evaporation concentration is high, the liquid viscosity larger easy flow evaporation, easy scaling, evaporation, evaporation and crystallization equipment is one of the current world's most advanced combination.
Evaporation capacity：
1000～100000kg/h（series）
Depending on the characteristics of the material and the amount of evaporation, a single effect or multi effect evaporation unit can be designed.
The device is mainly applicable to solution with crystal precipitation.
Mainly used in the chemical industry, metal smelting, large steel pickling waste liquid, power plant desulfurization waste liquid treatment and so on.
