Abstract
A filter cartridge with easier extraction provided by a roll-out clearance region for a radial seal is provided. The filter cartridge may be a two stage filter with the seal being located between stages and usable in a filtration vessel having a central separation wall with one or more riser pipes. Also, a new vessel is disclosed with multiple diameters for first and second stages of the housing with a larger second stage diameter as compared to the first stage, which can reduce door size and/or cause fluid flow velocities to be slower at the second stage relative to the first stage.
Claims24
An assembly for fluid filtration, comprising:
- a housing, and
- at least one filtration element supported within the housing;
- the housing including:
- i) an upstream housing portion with an inlet port for receiving a fluid stream to be filtered,
- ii) a downstream housing portion with an outlet port for discharging a filtered fluid stream,
- iii) a separation wall between the upstream and downstream housing portions, wherein the at least one filtration element is sealing and removably supported within an aperture of the fluid separation wall, enabling fluid entering the inlet port to flow into the at least one filtration element through an upstream portion of the filtration element and out of the at least one filtration element through a downstream portion of the at least one filtration element to the outlet port;
- and
- iv) a door on the upstream portion enabling access to the at least one filtration element, the upstream housing portion having an outer diameter that is smaller than an outer diameter of the downstream housing portion.
An assembly for fluid filtration, comprising:
- a housing, and
- a plurality of filtration elements supported within the housing in spaced relation;
- the housing including:
- i) an upstream housing portion with an inlet port for receiving a fluid stream to be filtered,
- ii) a downstream housing portion with an outlet port for discharging a filtered fluid stream,
- iii) a separation wall between the upstream and downstream housing portions, the separation wall being provided by a partition with openings having riser pipes mounted thereto, with each riser pipe defining an aperture;
- wherein each filtration element is sealing and removably supported within the aperture of a respective one of the riser pipes of the fluid separation wall, enabling fluid entering the inlet port to flow into the filtration elements through an upstream portion of the filtration elements and out of the filtration element through a downstream portion of the filtration elements to the outlet port;
- and
- iv) wherein the upstream housing portion has an outer diameter that is smaller than an outer diameter of the downstream housing portion.
