The leaf filter is divided into two types: vertical and horizontal. It is suitable for filtration and separation processes of decolorizing oil filtration, clarification filtration, crystals, etc. in the production of oil and chemical industries.
Vibration investigation vertical design is adopted, and multiple filter plates are integrated inside a single machine. The filter plate is composed of a multi-layer stainless steel filter screen, which is installed on the liquid collecting pipe in the cylinder. When the filtration time or the pressure difference reaches the set value, after the liquid is drained, the vibrating slag remover will vibrate the filter cake on the filter screen. Filter regeneration.
As the filtration time increases, more and more solid impurities are trapped, and the thickness of the filter cake continues to increase, which increases the filtration resistance of the system. When the pressure reaches the set value, the slag needs to be discharged. At this time, stop feeding the filtrate into the tank, and blow the compressed air overflow pipe into the tank, so that the remaining hydraulic pressure in the tank can be fed into another leaf filter. Then turn off the compressed air, when filtering decolorized oil or hydrogenated oil, steam is introduced into the tank; when filtering crude oil or other filtrate, compressed air can be blown into the tank to dry the filter cake. After the filter cake is blown dry, turn off the steam or compressed air, open the butterfly valve, start the vibrator, make the filter plate vibrate, and remove the filter cake on the filter screen.
