Sealing arrangement for apparatus for filtering, and methods, and products for filtering
View Patent ↗A device for filtering a gas stream, having a vessel partitioned into a first stage and a second stage, with an opening between stages. A filter element is positioned in the opening, with ends of the filter element extending into the first and second stages. The first member is removable from the second member while the filter element is positioned in the opening, to allow for replacement with a new clean member.
1. A apparatus for filtering a gas comprising:
a vessel having a partition dividing the vessel into a first stage and a second stage, wherein the partition defines an opening providing liquid communication between the stages;
a riser extending from the opening, said riser having a first end with a straight portion and a second end with a flared portion, with the straight portion positioned nearer the opening than the flared portion; and,
a filter element having at least a portion positioned in the riser the filter element comprising a first member having a first connection end and a first filtering characteristic, and a second member having a second connection end and a second filtering characteristic, wherein the first and second members are connected by a connection system in which the first connection end and the second connection end form a mating pair to provide the connection, with the second connection end defining a first groove extending circumferentially around the second connection end with a first seal member residing in the first groove, wherein at least a portion of the second connection end is positioned in the riser with the first seal member engaging the straight portion of the riser, wherein at least a portion of the first member extends toward the first stage, and at least a portion of the second member extends toward the second stage, wherein the first member is removable from the second member while the filter element is positioned in the opening, and wherein the first filtering characteristic and the second filtering characteristic are the same or different.
2. The apparatus of claim 1 , wherein the first and second connection ends form a mating pair by at least one of snapping, bolting, friction fitting, interlocking, engaging, coupling, hook/looping, adhering, adhesion with a time released adhesive, adhesion with a solvent releasing adhesive, magnetic coupling, locking, and threadably engaging.
3. The apparatus of claim 2 , wherein the second connection end defines a second groove extending circumferentially around the second connection end with a second seal member residing in the second groove, wherein at least a portion of the second connection end is positioned in the riser with the second seal member engaging the straight portion of the riser or the flared portion of the riser.
4. The apparatus of claim 3 , wherein the second seal member engages the flared portion of the riser.
5. The apparatus of claim 3 , wherein the second seal member engages the straight portion of the riser.
6. A apparatus for filtering a gas comprising:
a vessel having a partition dividing the vessel into a first stage and a second stage, wherein the partition defines an opening providing liquid communication between the stages;
a riser extending from the opening, said riser having a first end with a straight portion and a second end with a flared portion, with the straight portion positioned nearer the opening than the flared portion; and
a filter element having at least a portion positioned in the riser, the filter element comprising a first member having a first connection end and a first filtering characteristic, and a second member having a second connection end and a second filtering characteristic, wherein the first and second members are connected by a connection system in which the first connection end and the second connection end form a mating pair to provide the connection, with the second connection end defining first and second grooves extending circumferentially around the second connection end with a first seal member residing in the first groove and a second seal member residing in the second groove, wherein at least a portion of the second connection end is positioned in the riser with both the first and second seal members engaging the straight portion of the riser, wherein at least a portion of the first member extends toward the first stage, and at least a portion of the second member extends toward the second stage, wherein the first member is removable from the second member while the filter element is positioned in the opening, and wherein the first filtering characteristic and the second filtering characteristic are the same or different.
7. A filter system comprising:
a riser having a first end with a straight portion and a second end with a flared portion;
a filter element having at least a portion positioned in the riser the filter element comprising a first member having a first connection end and a first filtering characteristic, and a second member having a second connection end and a second filtering characteristic, wherein the first and second members are connected by a connection system in which the first connection end and the second connection end form a mating pair to provide the connection, with the second connection end defining a first groove extending circumferentially around the second connection end with a first seal member residing in the first groove, wherein at least a portion of the second connection end is positioned in the riser with the first seal member engaging the straight portion of the riser, wherein the first member is removable from the second member while the filter element is positioned in and remains in the riser, and wherein the first filtering characteristic and the second filtering characteristic are the same or different.
