I’d like to ask everyone: students who have just started working in the factory know nothing

I would like to ask everyone: there is an automatic backwash filter installed in the feed section of the diesel hydrogenation unit. I am not very familiar with automatic backwash filters, so I hope everyone can teach me the basic principles related to them. Additionally, I am particularly interested in knowing how such backwash filters are controlled
Normally, one unit goes through the filtration process while the other is on standby. The control panel has differential pressure monitoring; when the differential pressure reaches a certain value, it indicates that the filter needs to be flushed. First, bring the standby unit into operation; after running the two units in parallel for a while, disconnect the previously operating unit, release pressure, use diesel to flush in the reverse direction, and then drain the diesel. The core of the filter is similar to the tube side of a shell-and-tube heat exchanger. As for control, there is a sequential control. Press the button on the control panel to operate the opening and closing of the valve.
