Method, equipment and medium for controlling evaporation of waste liquid heat pump

Abstract

The invention relates to a method, equipment and a medium for controlling evaporation of a waste liquid heat pump. The method comprises the following steps: calculating the production discharge amount and the evaporation concentration frequency based on the concentration and the waste liquid amount of to-be-treated waste liquid; feeding an evaporation tower until the liquid level of the evaporation tower reaches a first preset liquid level threshold value; heating the evaporation tower until the detected temperature of the waste liquid reaches a first preset temperature; increasing the frequency of a compressor to a preset frequency set value; refluxing the distillate; feeding the evaporation tower again in response to determining that the conductivity of the distillate is lower than a preset conductivity threshold value; opening a distillate drain valve and closing a total reflux valve; and in response to determining that the production discharge amount of the distillate reaches the preset discharge amount threshold value or the concentration of the tower kettle concentrated solution reaches the preset concentration threshold value, discharging the concentrated solution. The waste liquid heat pump evaporation process can be automatically controlled, and the safety, reliability and stability of system operation are improved.

Problems solved by technology

[0003] At present, the automatic control and operation of domestic waste liquid heat pump evaporation treatment technology is still in the initial research stage. The control system and function of waste liquid heat pump evaporation are not perfect, and the degree of automation is not high. It needs to rely on manual operation and experience judgment, and the efficiency is low. , time-consuming, and bring great inconvenience to the operator

Especially when the heat pump evaporation device has an abnormal working condition, relying on humans to judge the abnormal situation and carry out corresponding processing, the cost of emergency response and processing is high, not timely enough, and it is easy to cause errors due to human factors, resulting in unqualified products, equipment damage, The device shuts down, and even causes serious losses such as waste liquid leakage

[0004] In summary, the traditional solution for controlling the evaporation of waste liquid heat pumps has the disadvantages of low degree of automation, poor operation safety, reliability and stability
