Definitions
- Filter unit for cleaning dust-laden process air.
- the invention relates to a filter unit for cleaning dust-laden process air.
- filter units for cleaning dust-laden process air are known, which are divided by a partition into an overhead clean air space and an underlying dust air space.
- dust filters of this type are known in which means, such as washing nozzles, are arranged in the dust air space between the filter bags inside or below the separating floor for cleaning the outside surfaces of the filter bags from adhering dust and product particles and operated periodically.
- the object of the invention is to provide a filter unit for cleaning dust-laden process air, in which the clean gas space or the clean gas and product gas space including filter tubes can be cleaned and the cleaning medium and the product residues are not disposed of from the clean gas space via the filter tubes and depending on the design the filter unit, the filter bags can also be cleaned from the inside.
- the design of the compressed air generator is arbitrary in a filter unit in the clean air space, but a separate activation of each compressed air generator must be possible.
- An advantage of the invention is that the impurities in the clean gas space and the cleaning medium can be removed from the clean gas space directly without stressing the filter bags. The cleaning medium and product residues can thus be disposed of outside the filter system.
- the filter hose can also be washed by compressed air pulses from the compressed air generator.
- washing nozzles in an upper partition plate, the washing nozzle bodies and the media supply are arranged outside the effective range of the filter products or the gases, as a result of which product residues can no longer settle on the washing nozzle bodies and the media supply and cleaning them is not necessary.
- the previous media supply lines for the individual washing nozzles are no longer required.
- This design gives the partition a high level of rigidity.
- washing nozzles can be arranged in the lower partition plate and / or in the tube walls of the partition openings. This also makes it possible to wash the hoses in the product gas space and the top of the hose or the pipe walls. This solution allows any arrangement of the partition openings in the partition, thereby optimizing the surface of the
- Dividing floor is accessible.
- the washing nozzles can be arranged independently of the arrangement of the dividing plate openings in the dividing plate.
- the hollow body of the dividing floor is divided on the inside into sections of any surface design, in the between the dividing floor plates Walls are arranged impermeable to media, with each department being assigned its own switchable access for washing medium.

- Support body is shaped.
- wash nozzles 8 are sprayed which can be activated for the washing and which spray the entire clean gas space 10 and the units arranged therein with wash water.
- the washing nozzles 8 are operatively connected to a switching valve 14 and its associated control 15.
- the partition 2 there is a channel 7 running on the circumference of the partition 2, which is in operative connection with at least one through opening 11 in the filter housing 1 and a downstream shut-off valve 12 for disposal of the cleaning medium and the product residues.
- the partition 2 with the channel 7 or the channel base is designed such that the cleaning medium and the product residues always flow to the through openings 11.
- the partition 2 is star-shaped or provided with channels 7, the ends of which run to the filter housing 1.
- the partition 2 can be arched in the direction of the clean gas chamber 10, as a result of which a channel 7 is virtually formed on the circumference of the partition 2.
- the cleaning of dust-laden process air in the filter unit is interrupted at predetermined periodic intervals.
- the washing nozzles 8 are activated by the switching valve 14 actuated by the control 15, so that the clean gas space 10 and the units arranged therein are sprayed and cleaned with cleaning medium, such as washing water.
- the cleaning medium and the product residues run off on the inner wall of the filter housing 1 and the aggregates and collect directly in the channel 7 and via a drain on the partition 2 in the channel 7 or in further channels 7.
- the cleaning medium runs through the controlled opening of the shut-off valve 12 and the product residues from the clean gas space 10. This is where the cleaning medium and product residues are disposed of outside the filter system. After closing the switching valve 14 and the shut-off valve 12 and then drying the entire inner filter system, the cleaning of the dust-laden process air can begin again.
- a compressed air generator 3 is arranged in the clean gas space 10 above each hose opening 6.
- Each of these compressed air generators 3 in the clean gas space 10 can be activated, in which a compressed air supply 4 is provided with a shut-off valve 16.
- An annular gap injector 13 for example, is used as the compressed air generator 3, as shown in FIG.
- any other compressed air generator 3 can be used for the filter bags 5. It is also within the scope of the solution that each compressed air generator 3 can be activated separately in the clean gas space 10, in which each one Compressed air supply 4 is assigned a shut-off valve 16.
- the mode of operation corresponds to that of the first exemplary embodiment.
- the filter bags are cleaned from the inside by activating the compressed air generator (s) 3, shown in the example as an annular gap injector 13, via the shut-off valve 16 and preferably delivering compressed air with reduced output.
- the compressed air has the effect that the washing water sprayed through the washing nozzles 8 is additionally conducted into the interior of the filter bags 5. This cleaning mist in the filter bags cleans them from the inside.
- the filter unit for cleaning dust-laden process air consists of the vertically aligned filter housing 1, which is divided into an overhead clean gas space 10 and an underlying product gas space 9 by means of a separating base 2.
- a plurality of partition floor openings 27 are arranged in the partition floor 2, in each of which a filter hose 5 which is open towards the clean gas chamber 10 is suspended and projects into the product gas chamber 9 hanging under its own weight.
- the partition 2 is designed as a hollow body.

- the hollow body of the separating base 2 is preferably divided on the inside into sections 21 in the form of segments of a circle, as shown in FIG. Each department 21 is assigned its own switchable switching valve 14 with control 15 for switching on the washing medium.
- a channel 7 is arranged on the circumference of the separating base 2 and is in operative connection with at least one through opening 11 in the filter housing 1 and a downstream shut-off valve 12 for the disposal of the cleaning medium and the product residues.
- the partition 2 or the upper partition plate 23 with the channel 7 or the channel base is designed such that the cleaning medium and the product residues always flow to the through opening 11.
- the partition 2 or the upper partition plate 23 is star-shaped or provided with channels 7 in any direction, the ends of which run to the filter housing 1.
- the dividing plate 2 or the upper dividing plate 23 can also be arched, as a result of which a channel 7 is virtually formed on the circumference of the dividing plate 2 or the upper dividing plate 23.
- the cleaning of dust-laden process air in the filter unit is interrupted at predetermined periodic intervals.
- the wash nozzles 8 arranged solely for the clean gas space 10 are activated by the switching valve 14 actuated via the control 15, so that the clean gas space 10 and the aggregates possibly arranged therein are sprayed and cleaned with cleaning medium, such as washing water.
- the cleaning medium and the product residues run off on the inner wall of the filter housing 1 and the optionally arranged units and collect directly in the channel 7 and via a drain on the top of the upper partition plate 23 in the channel 7 or in further channels 7.
