Auxiliary control system for wastewater evaporator

2025,07,14

(1) The liquid level control of the wastewater evaporator affects the progress of the evaporation operation. The liquid level is too high Steam consumption increases and evaporation time is longer; If the liquid level is too low, the crystallization or cat degree will be high, and the solution is prone to crystallization on the hot bamboo, thickening the film layer, affecting heat transfer and evaporation efficiency, and increasing steam consumption. Therefore, it is necessary to automatically control the liquid level of the wastewater evaporator. (2) The control of heating steam is affected not only by fluctuations in pressure, temperature, and liquid level, but also by controlled parameters that have a single value correspondence with product concentration, thereby affecting product concentration. Therefore, control should be implemented for heating steam. (3) The control of condensate discharge is very important, and if it cannot be discharged smoothly, it will affect the stable operation of the wastewater evaporator. The discharge of condensate can be carried out using a steam trap (steam trap). In order to prevent steam from being discharged, a buffer tank can also be added with automatic liquid level control. The auxiliary control system of the wastewater evaporator is not optional The so-called auxiliary control refers to the fact that their controlled parameters do not have a single value correspondence with the direct indicators of the product, but their impact on the smoothness, energy saving, and product quality of the evaporation operation is also important. Therefore, parameters must be selected and controlled for different process environments and conditions. (4) The energy-saving control of wastewater evaporator mentioned here refers to the full utilization of secondary steam generated during the evaporation process. For example, the material is first heat exchanged with secondary steam before entering the wastewater evaporator.
