Horizontal Pressure Leaf Filter (HPLF)
The horizontal pressure leaf filter is an enclosed filtration system and can be fully automated. This filter produces a high filtrate clarity after the clarification run and is also suitable for all kinds of filter aids.
The regeneration time between the filtration cycles is short.
Horizontal pressure leaf filters can also be delivered as tandem units to save floor space.
The pressure leaf filter itself has no rotating parts, keeping maintenance to a minimum. These advantages result in an economical filtration solution.
Key characteristics (sulphur filtration)
- Big filtration surface,
- Easy to clean filter plates,
- Heating jacket in order to prevent solidification
- The pressure leaf filter itself has no rotating parts, thus keeping maintenance to a minimum
These advantages result in an economical filtration solution. For cake discharge the carriage with the filter leaves is driven outside the tank with an electric or hydraulic system. With a Retractable Shell system, the filter leaves are exposed by moving the tank away from the bundle.
The bayonet ring is opened hydraulically. The cake discharge is easily done with the filter opened.
The Retractable bundle type filter is equipped with a self-sealing quick release manifold coupling which is steam heated.
The Horizontal Pressure Leaf Filter, which we supply in the filtration cycle of liquid sulphur, can be tailor made to fit your requirements, in any of the following setups:
The shell doesn’t move; the bundle with filter elements moves in and out of the shell.
Retractable shell with an overhead suspension frame
The bundle doesn’t move, the shell hangs from a support structure and moves over the bundle.
Retractable shell with a lower support frame
The bundle doesn’t move here either, the shell is supported by rails and moves over the bundle.
The leaf spacing is 125 mm to allow for precoat and longer filtration times. The filter leaves are mounted on a manifold which allows for easy removal and mounting of the filter leaves.
Features and benefits
- Vertical position for easy cleaning
- Retanglar filter screens, double sided
- Five layers of wire mesh
- Reinforced binding around the full circumference of the filter leaf to protect the rim during manual cake removal by tapping
