The film evaporator structure a lot, no matter what, in the design and production must be the refrigerant vapor heat transfer surface can leave soon and maintain a reasonable level, make full use of the heat transfer surface effectively. Refrigerant molecular distillation systems liquid throttling when a small amount of steam yan can through the gas-liquid separation equipment make gas and liquid separation, only they were separated off gas liquid film evaporator heat, in order to improve the he...

As the growth of the by film evaporator wiped film evaporator technology, all kinds of vacuum film evaporator also began to appear, vacuum film evaporator in the application of each industry is very broad, such as the following: 1, in the application of hard coating, cutting tools, moulds and wear-resisting corrosion resistant parts, etc. 2, in the application of protective coating: the blade of aircraft engine, automotive steel, heat sink, etc. 3, the application in the field of optical thin fi...

By film evaporator advantage significantly, falling film evaporator has a high coefficient of heat transfer, heat transfer temperature difference loss small, suitable for heat-sensitive materials, easy to implement multiple effect evaporation operation, suitable for viscous material advantages, such as, therefore widely used in the evaporation from all walks of life to work in the chemical industry, light industry and food processing is widely used in the industry, to achieve the goal of liquid ...

By film evaporator equipment is under the vacuum state through high temperature melt the metal aluminum evaporation, precipitation accumulation of the steam to the aluminium plastic film on the surface, so as to make the surface of the plastic film to equipment with metal gloss. It was film evaporator technology in the market at present, is produced as a specific film technology, now in real life, has jacketed glass reactor very extensive application. If after such technology, the product still ...

PTFE hollow fiber by membrane distillation porosity test by membrane distillation performance assessment has a strong guiding significance, in general, PTFE hollow fiber by membrane distillation of porosity in the following two ways for testing. Method: 1. Ethanol is PTFE hollow fiber membrane distillation in ethanol solution in 2 h, make completely immersed in ethanol solution by membrane distillation hole, hole cleaning by membrane distillation; Will be after completion of cleaning material of...

Big wash is discharge wash effect of water washing method. First of all, reduce the amount of admission, will effect the material liquid out, then add the condensate to liquid level, and improve the steam pressure, the boiling water thin film distillation to dissolve effect within the dirt, open the circulation pump irrigation pipes, when to reach the washing reault, the lower steam pressure, and water washing effect. If the scale is serious, can be carried out two times of washing. Small washin...
