The invention discloses a control method of liquid treatment equipment. The method comprises the following steps: a condensation control step of judging whether a condensation solution is generated in a distillation condensation tank in a set value T2 time period, entering a step S110 if yes and alarming if not; judging whether the viscosity of a solution in an evaporation chamber is greater than a set value VC or not, stopping running a cooling-heating circulation system and vacuum equipment if yes, judging whether running time of a stage I of distillation condensation is greater than a set value T3 or not if not, stopping supplying a raw solution if yes and entering a control step of a stage II of distillation condensation, and returning to the step S110 if not; a step S116 of judging whether the running time of the stage II of distillation condensation is greater than a set value T4, stopping running the cooling-heating circulation system and vacuum equipment if yes, and continuing to judge if not. The overall vacuum evaporation condenser is simple to operate and high in production efficiency, and is capable of treating a plurality of materials with different boiling points and implementing unmanned operation; meanwhile, the average energy consumption is reduced by about 60%.
Description
technical field [0001] The invention relates to a liquid processing device, in particular to a control method and device for a liquid processing device, and belongs to the technical field of evaporation and condensation. Background technique [0002] In water treatment, medicine, food, chemical and other industries, it is usually necessary to distill or concentrate the raw liquid. At present, vacuum vacuum distillation equipment is generally used to achieve this. The existing vacuum distillation equipment mainly includes evaporation tanks and condensers. After evaporating and vaporizing through the evaporation tank, it is condensed and liquefied by the condenser to obtain a liquid with high purity or high concentration. [0003] In the process of realizing the present invention, the inventors found that the existing vacuum vacuum distillation equipment has scattered structures, takes up a lot of space, has low production efficiency, complex operation, requires full-time pers...
