In other words, when filter 5 is clogged, the value of the differential pressure (A 1 - A 2 ) between pressure gauges A 1 and A 2 becomes abnormally high, and when filter 6 is clogged, the pressure on pressure gauge A 2 becomes abnormally high. It gets expensive. When this clogging is detected, the valves V 1 , V 2 or
Close V 3 and V 4 , and conversely close the valve on the bypass pipe 8 side.
V 5 and V 6 are opened to perform filtration using the spare filters 9A and 9B, and during this period, the clogged filters 5 and 6 are replaced. After the replacement, the valves V 5 and V 6 on the side of the bypass pipe 8 are closed, and the valves V 1 to V 4 on the side of the main pipe 4 are opened again, and filtration is performed using the regular filters 5 and 6.
