How to prevent the phenomenon of tube blockage in the evaporator?

The low vacuum of the evaporator is too low to maintain the boiling point of the concentrate, and the temperature of the secondary steam increases, thereby reducing the temperature difference between the heating steam and the concentrate, reducing the heat transfer and slowing the steam evaporation rate, and the heating temperature of the heating material affects the preservation of the active ingredient. The vacuum is too low, in addition to affecting the quality, but also reduce the production capacity of the equipment. The evaporator may be blocked in the process of operation, due to the long time of use, there will be a large amount of dirt accumulation.

Evaporator is used for the characteristics of high salt and high concentration of chemical organic three-effect. Based on the principle of evaporation and crystallization, forced circulation evaporation and crystallization is adopted to vaporize and crystallize the salt in the concentrated liquid. After evaporation, the condensed water can achieve the three-effect discharge standard after subsequent treatment.

In general, there are two reasons for pipe blocking:

1, crystal salt deposition.

2. Scale formation caused by calcium and magnesium ions.

Therefore, the prevention of pipe blocking should start from these two aspects. First of all, the evaporation form should be selected, such as falling film evaporator and other film evaporator is not suitable for the occasion of crystal production, if the use of falling film evaporator and other film evaporator, tube blocking is a phenomenon, so in the occasion of easy to produce crystals should be used three-effect evaporator.

During the operation of the evaporator, there are many kinds of wastewater treatment. In the process of use, the characteristics of wastewater are diverse, and the treatment methods are also diverse. Evaporator sewage or sewage treatment method is based on the characteristics of the liquid, the use of multi-effect evaporation process, multi-effect evaporation and drying process, if you need evaporator equipment can contact us at any time, let us better introduce our products for you, I believe you can make better use of
