Logical, upper valve port is connected to right valve port, and into cold process is blown, B drier 4 can either be cooled down by blowing cold process, while to pre-dryer 6
It is regenerated.
Primary industry gas passes through third four-way valve 7, and the first four-way valve 2 cools down it into B drier 4；So
Postindustrial gas enters heater 8 by the second four-way valve 5, is warming up to 140 DEG C；Industrial gasses after heating enter pre-dryer
6, the moisture in pre-dryer 6 is desorbed, after then heating up and the industrial gasses containing moisture are using third four-way valve 7, enter
Cooler 9；After heating and the cooled liquefaction of the moisture of the industrial gasses containing moisture, the cooling industrial gasses containing water enter back into
Knockout drum 10 is separated, industrial gasses after separation access flow restriction control valve 1 and then defeated by primary industry gas
Enter pipe main pipe and enter drying system, is dried.
After adsorbent adsorption saturation in A drier 3, switches the first four-way valve 2 and the second four-way valve 5, make the one or four
2 lower valve port of port valve is connected to right valve port, and upper valve port is connected to left valve port, and 5 lower valve port of the second four-way valve is connected to right valve port, upper valve
Mouthful be connected to left valve port, B drier 4 carries out the dry of industrial gasses and adsorbs, while A drier 3 is regenerated, drying process and
Regenerative process repeats no more.
