Definitions
- the invention relates to a method for cleaning filter candles of a candle filter using a cleaning liquid flowing into the inside of the candle from the filtrate side, which is pressed in the opposite direction from the filtrate direction by a pressurized gaseous medium from the inside out through the filter candles and on an apparatus for performing this method.
- the filter cake set on the filter on the non-filtrate side of the filter device is removed by filling the interior space on the supply side and part of the filtrate space located above the interior space on the supply side with the discharge side closed, from the non-filtrate side, with water the air standing above the water is compressed in the filtrate space.
- a cleaning liquid is brought to overpressure in a separate container and fed to the cleaning device via a feed line for carrying out the cleaning, and from there it is pressed through the filter in the direction opposite the filtering direction.
- a gaseous medium under excess pressure is used to convey the cleaning liquid from the collected container to the filtering device.
- Water is expediently used as the cleaning liquid and air as the gaseous medium.
- nozzle-shaped constrictions are provided on the discharge-side candle end or baffles are arranged at a distance from this constriction, with which the inflowing cleaning liquid is deflected in all directions in the direction of the candle inner walls.
- a disadvantage of this is that the nozzle-shaped constrictions are provided both for the supply of the cleaning liquid into the interior of the filter candle and for the compressed air, so that when a pressure impulse is given, a follow-up of the cleaning liquid is not possible.
- the invention has for its object to find an improved solution with which, despite the supply of the pressurized gaseous medium, there is still an automatic run-on of the cleaning liquid into the interior of the candle, so that practically constant exposure of the interior of the candle to this cleaning liquid is ensured can be.
- this is achieved in a method for cleaning filter cartridges in that the cleaning liquid and the gaseous medium are brought into the interior of the filter cartridge by separate flow paths. It has proven to be expedient in an independent embodiment in the invention that a constant liquid film is maintained while the cleaning liquid supply is maintained and this can be acted upon by pulsating compressed gas supply.
- the time intervals of the pulsating pressurized gas supply correspond at least to the temporal structure of a liquid film which acts on the inner wall again, or the pulsating pressurized gas supply is only initiated as soon as there is an on the inner wall of the candle has formed the entire length of the liquid film.
- the invention further relates to a backwashable filter arrangement with a separating plane arranged between the unfiltrate and filtrate space and filter candles held therein with its upper end, the interior of which has its front opening in the filtrate chamber, the front opening having two separate openings which differ in height Levels end.
- the front opening of the filter candle has a supply line for cleaning liquid and a second supply line for a pressurized gaseous medium that is separate and ends at a higher level.
- the supply line for cleaning liquid is designed as an annular gap which is formed on the one hand by the inner wall of the filter candle and on the other hand by a pipe section provided for the supply of a gaseous medium, and this pipe section above the filter candle and / or the Annular gap ends.
- the method according to the invention and the backwashable filter arrangement designed for this purpose ensure that practically a constant liquid keitsfilm from the Fiitratraum can flow into the interior of the filter candles and thus forms a closed liquid film on the inner wall, which causes a uniform and safe detachment of the filter cake when pressurized.
- the liquid film provided for cleaning can be built up inside the candle within a very short time, as a result of which the filter cake can be detached much faster and better.
- Figure 1 is a filter housing with built-in filter cartridges
- Figure 2 is an enlarged view of a portion of the filter cartridges.
- the unfiltrate space 2 consists of a cylindrical part with a collecting space 2 'tapering downwards in a conical shape, the opening angle alpha of which is approximately 40-70 °. Both rooms 1 and 2 are separated from each other by an intermediate floor 3 with holes for receiving filter elements 4.
- the lower part of the collecting space 2 ' has a nozzle 5 which serves for the supply and suitable distribution of the unfiltrate and for the removal of the filter residues.
- the front opening 6 of the filter candle has two openings 7, 8 which are separate from one another and which end at different levels in terms of height.
- the front opening 6 of the filter candle forms a feed line 7 for cleaning liquid and a second feed line 8, which is separate from it and ends at a higher level, for a pressurized gaseous medium.
- the feed line 7 for the cleaning liquid is expediently designed as an annular gap which is formed on the one hand by the inner wall 9 of the filter candle and on the other hand by a pipe section 10 provided for the feed of a gaseous medium. This pipe section 10 ends above the filter candle and / or the annular gap.
- the annular gap formed in this way expediently begins with the front upper end 11 of the filter candle and / or its attachment and has a length that ensures a closed liquid film formation on the candle inner wall 12.
- appropriately designed guide elements can additionally be provided within the annular gap.
- the passage opening can be provided by suitable machining of this head part.
- a film which is closed in one piece on the entire inner surface of the filter candle is achieved immediately after the flushing medium has passed through.
- the thickness of the film can be adjusted precisely via the size of the gap, thus allowing the cleaning to be precisely coordinated.
- the gap is formed by targeted milling or by applying corresponding spacers 13 in a two-part design.
- the film can also be adapted to the medium and its properties along the length of the gap. The film produced can be used both for cleaning the inner wall and for cleaning the outer wall and the passage gaps of the filter medium.
- a pressure surge is generated with prestressed gas, which pushes the precisely adjusting medium film outwards at almost all points inside the filter body.
- a pulsating pressurized gas supply can also be provided at intervals, the time intervals of which correspond to the build-up of a liquid film which acts on the inner wall after the pressurized gas supply has been carried out.
