How to control the temperature of the solution inside the evaporator
Thread Content
Seniors, please tell me how to generally control the temperature of the solution in the evaporator? Is it by controlling the temperature and pressure of steam? This post was last edited by brainandrain on 2009-2-14 13:47 ]
There are many ways to control it. For example, adjusting the flow rate of the solution, the inlet temperature, adjusting the inlet and outlet temperature of the steam, the flow rate of the steam, etc.
The temperature of the incoming steam is certain, and the main purpose is to control the steam flow, which can be controlled by the system steam pressure.
Generally, the evaporator temperature and heating steam flow are cascade controlled. The evaporator temperature is adjusted by controlling the heating steam flow.
Generally, the evaporator lower liquid temperature is controlled, but in order to adjust in time without lag, steam pressure changes are sometimes used as the adjustment input variable, that is, cascade control is used.
:lol Is this supposed to be a question of control selection? The liquid cannot be changed because it involves output, so what can be changed is the steam flow. Therefore, the control valve should be added to the steam pipe, and the detection element should be placed on the evaporator wall. Open a hole and insert a threaded pipe and it will be OK.
