Definitions
- the invention relates to a filter device with at least one filter unit accommodated in a filter housing, which comprises at least one hollow fiber clamped between two pores with a wall permeable to water vapor, according to the preamble of claim 1.
- a hollow fiber filter device is known from WO 2013/100677 A1.
- the filter device is used for moistening a dry air stream by the water vapor permeable hollow fibers of the filter module, through which a dry air stream is passed, are flowed in the radial direction of a moisture-enriched air stream.
- the hollow fibers are part of a filter unit, which is inserted into a receiving filter housing, wherein the hollow fibers are clamped between two end-side potions, on the outside of which sealing rings are arranged in order to achieve a seal against the housing inner wall of the receiving filter housing. Disclosure of the invention
- the invention is based on the object to form a hollow fiber filter device with simple design measures with a high efficiency.
- the hollow fiber filter device according to the invention can be used as moistening device to enrich a gas fluid flow with moisture.
- the filter device is z. B. used as a humidifying device for the air to be supplied to a fuel cell.
- the filter device has in a filter housing at least one filter unit with at least one hollow fiber, which is clamped between two end pottings and has a water vapor permeable wall.
- a second fluid flow in the filter housing of the filter device wherein the two fluid streams differ in their moisture content.
- a moisture exchange is carried out from the moister fluid flow to the drier fluid flow.
- a dry air stream is guided inside the hollow fibers and a moisture-enriched air flow outside the hollow fiber, so that water vapor can pass through the wall of the hollow fiber radially from outside to inside.
- a moisture-enriched air flow is conducted within the hollow fibers and a dry air flow outside the hollow fiber so that water vapor can pass radially through the wall of the hollow fiber from inside to outside.
- the air stream referred to as the dry air stream, preferably has a lower relative humidity than the air stream designated as enriched with moisture.
- the first and the second fluid flow advantageously both run in the axial direction, in particular axially in opposite directions. This means that advantageously the air flow guided outside the hollow fiber should be guided essentially along the hollow fiber and counter to the flow direction within the hollow fiber.
- a flow gap is formed between the potting on an end face of the filter unit and the receiving filter housing, through which the second fluid flow guided outside the hollow fiber is passed.
- the flow gap is preferably used for the derivation of the fluid flow conducted outside the hollow fiber; In principle, however, a flow direction in the opposite direction into consideration, so that the outside of the hollow fiber guided fluid flow is passed over the flow gap in the interior of the filter housing.
- an axial flow guide without flow deflection is possible over the flow gap, which extends the residence time of the second fluid flow in the immediate vicinity of the wall of the hollow fiber and improves the moisture exchange between the first and the second fluid flow inside or outside the hollow fiber. Overall, the efficiency of the moisture exchange can be improved in this way.
- the pottings are formed differently large at the opposite end faces.
- the flow gap is in this case between the smaller Pottung and the inside of the filter housing or a housing-side component.
- To the size difference between the potties too Bridging the hollow fibers clamped in the pottings runs at a small angle relative to the longitudinal axis of the filter device and the filter housing, which is preferably less than 10 °, in particular not more than 5 °, where appropriate the angle between the longitudinal axis of the hollow fiber and the longitudinal axis of the Filter device or the filter housing can only be a maximum of 1 ° or 2 °.
- the flow gap can be circumferential and surround the potting approximately or completely annularly, whereby a uniform flow of the current conducted outside the hollow fiber is ensured over the circumference.
- a plurality of hollow fibers are clamped between the two axially opposite pottings, which run at an angle in the filter device at different sized total areas of the potties, so that a hollow fiber bundle is arranged between two pottings.
- the flow gap is located at that end face in which the total cross-sectional area of the pottings is smaller.
- the pottings are expediently flow-tight against each other in order to prevent faulty currents. It may be expedient to use the potties in a holding frame with a grid corresponding to the pottings, wherein the holding frame is received in the filter housing. At the end face with the smaller total cross-sectional area of the flow gap is located on the outside of the holding frame and the inside of the female filter housing.
- the filter device has at least one filter unit in a filter housing, wherein the filter unit comprises at least one hollow fiber clamped between two pottings, preferably a plurality of hollow fibers has between two Pottungen and the hollow fiber is formed water vapor permeable.
- the filter unit can have several pottings per end face, in each of which one or more hollow fibers are clamped.
- the Pottungen can be added to each end face in a holding frame with screening.
- a flow tube is introduced, via which the fluid flow is guided, which extends outside of the hollow fiber. The flow tube is therefore outside of the recorded in the potting hollow fiber.
- This embodiment has the advantage that due to the integration of the flow tube into the potting in the case of a small-sized design, an axial flow guidance of the fluid flow conducted outside the hollow fiber is provided in this section.
- the potting with the flow tube is located on the axially opposite side to the potting with outside flow gap.
- the potting with the outside flow gap has no integrated flow tube. If several pottings are provided per end face, in each case one flow pipe can be integrated on one end face into each individual potting. On the axially opposite side, on the other hand, there are no flow pipes integrated into the pottings.
- the combination of integrated flow tube into a potting in the region of an end face and circumferential flow gap in the region of the axially opposite end face has the advantage that the fluid flow running outside the hollow fiber runs at least approximately parallel to it over the entire axial length of the hollow fiber.
- a bundle of hollow fibers is provided, which are arranged in a potting, in particular embedded in this, wherein the flow tube is surrounded by the bundle of hollow fibers.
- the flow tube integrated into the potting can extend over the entire axial length of the potting.
- the flow tube protrudes on the hollow fiber side axially beyond the potting, wherein in the wall of the protruding portion flow openings can be introduced, via which an additional inflow or outflow of the fluid is possible.
- the flow tube projects beyond the potting on the side facing away from the hollow fiber.
- the flow tube ends on the hollow fiber side at the axial end face of the potting.
- the flow tube is inserted centrally into the potting. This has the advantage, in particular in the case of a hollow fiber bundle per potting, that the fluid flow is guided within the hollow fiber bundle and thus all the hollow fibers of this bundle are flowed through in at least approximately the same way by the fluid flow.
- FIG. 1 shows a longitudinal section of a filter device which can be used for humidifying an air flow, with a filter unit which comprises hollow fibers clamped between end-side seats and walls permeable to water vapor;
- 2 shows the filter unit with two axially opposite frontal pottings, between each of which a plurality of hollow fibers extend, with a flow tube integrated in a potting;
- Fig. 4 is an end view of pottings without flow tube, but with a circumferential flow gap.
- the same components are provided with the same reference numerals.
- the filter device 1 shown in the figures can be used as moistening device to enrich a dry air flow in the countercurrent process with moisture.
- the filter device 1 has, as shown in FIG. 1, a filter housing 2, in which a filter unit 3 is received.
- the filter unit 3 comprises a multiplicity of hollow fibers 4, which extend axially between pottings 5, 6 and are firmly held in the pottings 5, 6.
- the hollow fibers 4 consist for example of an organic and / or inorganic material and have a water vapor permeable wall.
- Fig. 1 for reasons of simplified illustration, only a single continuous hollow fiber 4 between Pottitch 5 and 6 is shown; In fact, as shown in Fig. 2, between the pottings 5, 6 run a plurality of such hollow fibers.
- a second fluid stream 8 is passed through the filter housing 2 in the filter device 1, which is preferably a high-moisture air stream; the second fluid stream 2 extends outside the hollow fibers 4. Due to the water vapor permeability of the wall of the hollow fibers 4, passage of water particles radially through the hollow fiber wall is possible, whereby the first fluid stream 7 is enriched with moisture within the hollow fiber.
- the filter unit 3 Per axial end face, the filter unit 3, as can be seen in connection with FIG. 3 and FIG. 4, comprises a plurality of pottings 5 and 6, which are arranged side by side and respectively receive a plurality of hollow fibers 4.
- a hollow fiber bundle with a plurality of hollow fibers 4 is shown, each extending between two individual, axially opposite Pottungen 5 and 6 and are firmly clamped in the Pottungen.
- the individual pottings 5 and 6 are accommodated in a holding frame 9 (FIGS. 3, 4) which is provided with a grid with longitudinal and transverse struts and offers a rectangular grid receptacle per potting 5 or 6.
- the various pottings 5 and 6 are fluid-tightly received in the holding frame, so that erroneous currents are avoided on the edge side of each Pottung.
- each potting 5 In the region of a first axial end face, in each potting 5 a respective flow tube 10 is integrated, via which the second, moisture-enriched air stream is directed into the interior of the filter device 1, which flows axially along the outside of the hollow fibers.
- the flow tube 10 is integrated centrally into each potting 5, the hollow fibers 4 extend outside of the flow tube 10.
- the flow tube 10 has a greater axial length than the potting 5 and projects beyond the potting 5 axially at its two end faces.
- the wall of the axially projecting on the hollow fiber side portion of the flow tube 10 may have flow openings through which the incoming, moist air flow is additionally distributed in the interior of the filter unit 3.
- the flow tubes 10 are introduced into each individual potting 5 in the region of an end face of the filter unit 3.
- the axially opposite Pottungen 6, however, have no such flow tube.
- the pottings 6 without a flow tube are smaller in comparison with the pottings 5 with a flow tube and correspondingly have a smaller cross-sectional area, so that the total cross-sectional area, formed from the sum of all pottings per end face, is smaller in the region of the pottings 6 than in the region
- This embodiment together with the supply of the second fluid stream 8 via the flow tubes 10, has the advantage that the second moisture-laden fluid stream 8 flows along the entire free axial length of the hollow fibers 4, resulting in efficient delivery of water vapor through the hollow fiber wall and thus ensures a good moisture accumulation of the first fluid stream 7 within the hollow fibers.
- the flow gap 1 1 is formed circumferentially.
- the potions 6 are held in a fastening part 12 which is supported on the end face of the filter housing 2.
