There is provided method and apparatus for creating a longitudinally disposed, sharp pulse of liquid, useful for pulseback renewal of liquid-entry faces of a panel-bed liquid filter or a panel-bed liquid-powder contactor. Perforations are disposed along the wall of a tank in a path generally parallel to the tank's axis. Stoppers are provided for stoppering the perforations. With the perforations so stoppered, a liquid is introduced at high pressure into the tank. Thereafter, a quick unstoppering of the perforations releases the liquid from the tank in form of a longitudinally disposed, sharp pulse of liquid moving in a direction perpendicular to the tank's axis. If the tank is placed vertically alongside or within a space that in normal operation receives liquid from a panel bed, the sharp pulse can effectively pulseback the panel bed.

1. A method for renewing liquid entry faces of a bed comprising granular material, comprising: producing countercurrent pulses of liquid into a bed of granular material, into a vertical supply column of the granular material in the bed, causing the granular material to move bodily toward liquid entry faces of the granular material in the bed;spilling granular material from liquid entry faces of the bed, and making good loss of the granular material in the spilling from the vertical supply column;producing a longitudinally disposed, sharp pulse of liquid into a treated liquid space adjacent the bed by:providing a vertical tank in the treated liquid space, said vertical tank, the tank having an outer cylinder with a cylindrical wall and upper and lower ends,disposing perforations longitudinally along the cylindrical wall, wherein the perforations are spaced from each other in a path parallel to an axis of said vertical tank;stoppering said perforations; and sequentially:introducing liquid at elevated pressure in said tank;quickly unstoppering said perforations, thereby releasing said liquid from said vertical tank in form of longitudinally disposed, sharp pulses of liquid into the treated liquid space in a direction perpendicular to said axis of said vertical tank, wherein the perforations are in a small portion of a circumference of said vertical tank, and thereby pulsing liquid through the vertical supply column and spilling granular material from the liquid entry faces. 2. The method of claim 1, wherein said path is a straight line. 3. The method of claim 1, wherein said vertical tank comprises a first cylinder with a first set of perforations disposed along a first path;the first cylinder having an upper plate and a lower plate and having a connection in the lower plate for introducing liquid at elevated pressure in said vertical tank;said stoppering comprises placing a second cylinder fitting snugly within said first cylinder, an axis of said second cylinder being identical with an axis of said first cylinder;the second cylinder having a cylindrical wall, upper plate and an open lower end;in the cylindrical wall of said second cylinder, disposing a second set of perforations longitudinally along a second path, identical to said first path, yet also disposing said second set of perforations such as not to be in registry with said first set of perforations;wherein the first and second sets of perforations have the same dimensions;after introducing liquid at elevated pressure in said first cylinder, quickly moving said second cylinder and allowing the two sets of perforations to come into registry, thereby unstoppering said first set of perforations. 4. The method of claim 1, wherein said longitudinally disposed, sharp pulse effects the pulseback of a panel bed of granular solid material employed for liquid filtering or liquid-powder contacting. 5. The method of claim 1, further comprising a panel bed holding granular material disposed vertically parallel to said vertical tank with the perforations in said vertical tank facing the panel bed, wherein the perforations in said vertical tank are aligned with the panel bed. 6. The method of claim 5, wherein the panel bed has a liquid entry surface and an opposite liquid exit surface and the perforations are directed toward the liquid exit surface to cause granular material spills from the liquid entry surface of the panel bed. 7. A method for renewing liquid entry faces of a panel bed comprising liquid contacting granular material, comprising: providing producing a countercurrent contacting a liquid and a liquid contacting granular material;flowing the countercurrent into a panel bed of the liquid contacting granular materialthrough a vertical supply column of the liquid contacting granular material in the panel bed and out through liquid entry faces of the liquid contacting granular material in the panel bed;spilling the liquid contacting granular material from liquid entry faces of the panel bed, and making good loss of the liquid contacting granular material in the spilling from the vertical supply column;pulseback of a panel bed of granular solid material employed for liquid filtering or liquid-powder contacting through action of a longitudinally disposed, sharp pulse of liquid, by:placing a vertical tank within or alongside a space receiving treated liquid from a liquid-exit side of said panel bed, a height of said vertical tank being substantially identical to a height of said space;in said vertical tank, disposing perforations longitudinally along a path parallel to an axis of said tank;stoppering said perforations; and sequentially:introducing liquid at elevated pressure in said vertical tank;quickly unstoppering said perforations, thereby releasing said liquid in form of a longitudinally disposed, sharp pulse of liquid moving into said space, thereby effecting the pulseback of the treated liquid through said panel bed. 8. The method of claim 7, wherein said vertical tank comprises a first cylinder with a first set of perforations disposed along a first path;the first cylinder having an upper plate and a lower plate and having a connection in the lower plate for introducing liquid at elevated pressure in said vertical tank;said stoppering comprises placing a second cylinder fitting snugly within said first cylinder, an axis of said second cylinder being identical with an axis of said first cylinder;the second cylinder having a cylindrical wall, upper plate and an open lower end;in the cylindrical wall of said second cylinder, disposing a second set of perforations longitudinally along a second path, identical to said first path, yet also disposing said second set of perforations such as not to be in registry with said first set of perforations;after introducing liquid at elevated pressure in said vertical tank, quickly moving said second cylinder and allowing the two sets of perforations to come into registry, thereby unstoppering said first set of perforations and flowing the longitudinally disposed, sharp pulse of liquid into the space receiving treated liquid. 9. Apparatus for renewing liquid entry faces of a panel bed comprising liquid contacting granular material, comprising: a panel bed of liquid contacting granular material having liquid entry faces; a space receiving treated liquid inside the panel bed; a vertical tank within the space receiving treated liquid inside the panel bed for producing a longitudinally disposed, sharp pulse of liquid in the space receiving treated liquid inside the panel bed;a vertical tank having a cylindrical wall;the cylindrical wall having perforations disposed longitudinally along a path parallel to an axis of said vertical tank;wherein the perforations comprise a small fraction of the cylindrical wall of said vertical tank;stoppers movable by a first movement into a first set of positions whereby said perforations are stoppered and also movable by a quick second movement into a second set of positions whereby said perforations are unstoppered;a source of liquid at elevated pressure, a connection between said source and an interior of said vertical tank, and a valve in said connection, wherein opening the valve when said stoppers are in said first set of positions, causes said vertical tank to be filled with said liquid at elevated pressure, so that said quick second movement releases said liquid from said vertical tank in form of a longitudinally disposed, sharp pulse of liquid in a direction perpendicular to said axis of said vertical tank into the space receiving treated liquid for pulsing liquid in a counter current through the space receiving treated liquid inside the panel bed and into the panel bed of liquid contacting granular material and spilling portions of the liquid contacting granular material from the liquid entry faces. 10.
