Description

Heatshirts DESCRIPTION Technical area

The invention relates to a filter for the purification of fluids, in particular for the suspension of the finest liquid and / or solid particles from waste air, waste water and / or process gas streams, comprising at least one filter element which is to be filtered Medium is flowed through, wherein the medium can either be sucked through the filter element or the test tube can be read through the filter.

[0002] The invention also relates to a device for purifying exhaust air, waste water and / or process streams which has the same type as that used in the art.

State of the art Filters for purifying exhaust air, waste water and / or process gas streams of the type mentioned in the introduction are already known from the prior art. DE60014627 T2 describes such a device, which is equipped with a multiplicity of cylindrical filter elements, through which a fluid flows around the filter elements surrounding the housing from outside to the medium.

[0004] In addition, a device for purifying exhaust air and process gas streams is known from the published patent application DE 2731755 A1, which consists of a housing provided with gas supply and discharge lines, a centrally arranged rotationally symmetrical central body in the housing, designed as an FHter, wherein the medium to be cleaned by its own flow rate and corresponding structural design of the Fite relements is set in rotation, as it ss acting on the particles centrifugal forces radially accelerate to the outside, the particles are separated from the gas stream and pressed against the wall of the filter element.

DE 202006019878 U1 discloses a pus for purifying gases with a gas-tight housing, comprising a gas inlet opening and a gas outlet opening, wherein between the gas inlet opening and the outlet opening in a row of joints e e he he n are, with the lower side of the housing is followed by a KegeFörmiges lower part.

The aforementioned devices and pus elements all have the Nac htei on that they do not clean themselves and therefore by means of an (additional) cleaning process must be cleaned. For example, to purify the elements in DE60014627 T2, a flushing fluid is supplied to the outlet opening of a single valve, the flushing fluid entraining a portion of the purified gas contained in a cap, as shown in FIG Let the parents keep it in check.

[0007] Of the substances retained on a parent (usually EBsubstances), a so-called puff cake is formed, which increases in the course of the elutriation, since the finest liquid and / or solid particles are retained continuously. As the thickness of the pus cake increases, there is the negative effect of an increasing flow resistance of the puff, which in turn leads to an increasing power requirement for the flow of the parent or, in the case of limited power, to a decrease in the volume flow rate Performs parent. For this reason, the product must be cleaned for some time. This is done regularly by backwashing or in the gas phase usually by introducing a pressure pulse on the downstream side of the egg medium. In addition, there is no such thing as a remedy for the abatement of the European Union. Representation of the invention

[0008] The object of the present invention is to provide a means for purifying hides, in particular for obtaining the finest liquid and / or solid particles from exhaust, sewage and / or process gas streams which is suitable to be cleaned independently with and without further aids (or auxiliary energy).

Eifindungsgemäß the above object is achieved with the features of claim 1. Advantageous embodiments of the invention in accordance with Eilte rs are given in Uhteransprüc hen.

[0010] Thereafter, an EUter of the type mentioned in the opening paragraph is characterized in that the accelerated element is rotatably mounted, wherein at least one device is provided on the element, which rotates the driven element, the rotation being caused by the rotation of the element Once again, particles have to be separated from the parent by means of centrifugal force. [0011] Suitable for use in rapid recirculation are, for example, extrudates well-known from the state of the art, such as, for example, heated spun fabrics, nonwovens, porous solids, wounded polyester plaques with the game, woven fabric made from a very wide variety of materials , Papers, whereby, depending on the field of application, a wide variety of materials are used, for example fine fibers (made of polyester, polyphenylene sulfide, polytetrafluorethylene, etc.), ceramic fibers or sintered fibers, glass fibers or even metals. In addition, the surface of the hurried re learning duck can be shaped differently or configured, for example. Smooth or jagged, the rushed relement can also, for example. Consist of a stretched on a raw frame Eilte towel. As a device are preferably flow they itvo nie htungen (eg. In Fbim of flow baffles or the like) into consideration, which inside and / or outside the Elte le me nts at the (inner and / or the outer) wall are arranged.

According to the invention, a shape and arrangement of the flow they itvo nie htungen chosen that can be realized with the simplest Hersteilungsmethoden. Here the arrangement of the flow depends on it first and foremost on the formation and mode of functioning of the pus.

The flow directing devices are arranged on the pus element that the pus element is offset by means of the incoming air, water or gas stream in Egenrotation without requiring another source of energy erforderiic h.

The pus element is thus directly set in rotation by the inflowing exhaust air, waste water and / or the process gas stream, whereby the particles to be discharged by means of the force of force independently separate from the pus element due to the rotation of the element.

In a particularly advantageous embodiment of the invention, the parent element is disposed within a cylindrical and / or (semi-) cone-shaped pus container surrounding the pus member, the exhaust, sewage and / or process gas stream being directed outwardly from the pus member to the outside into the space of the pewter vessel flows outward into the elite element.

In another advantageous embodiment of the invention, the device consists of one or more wheels. The impeller is here understood to mean a moving (rotating) part of a flow sma sc, which involves the flowing exhaust air, waste water and / or process gas flow, in particular in a sample. TheVortei of the erfind ungsge MAESSEN filter consists, inter alia, in that this can be arranged long in contrast to the known filters of the type mentioned also horizontally, obliquely or in any x-cheap hints.

To cre ate for the purpose of marking

Further objects, features, advantages and possible applications of the filter according to the invention will become apparent from the following description of a number of exemplary embodiments with reference to the drawings. All described and / or historically presented features alone or in any arbitrariness form the subject matter of the invention, regardless of the summary in individual claims or their repercussions.

[0021] Fig. 1 shows a filter in a preferred embodiment sfo rm in a perspective view;

Figure 2 shows an apparatus for purifying exhaust, wastewater and / or process gas streams with multiple filters;

[0023] FIG. 3 shows a filter in a further embodiment in perspective view.

Execution of the determination

The illustrated in Flg.l advantageous embodiment of the invention Fifindung shows a filter in a preferred embodiment in perspective Ansic ht. As can be seen from FIG. 1, the filter 1 in an advantageous embodiment has a flow device 4 in the form of an impeller, preferably in the form of a propeller 4, according to the invention, preferably consisting of a ring of blades (hills, rotor blades , ...) consists, which are held by a suitable attachment on a shaft 6, which durc h learn the filter nt 2 and is fixed to this. The shaft 6 and the filter learn nt 2 are stored at least one point (storage of the pus member 5).

The propeller 4 is arranged on the filter element 2 such that the filter element 2 is self-rotated by means of the inflowing air, water or gas flow. As can be seen from FIG. 1, fluid 3 to be filtered flows from a flter container 7 surrounding the filter element 2 from the outside through the filter element 2 into its cavity 2 a. There it flows upwards and puts the Pro eller 4 in rotation, wherein the propeller 4 in turn sets the filter element 2 in self-rotation.

In this process, no additional energy is required in principle. If, however, the fluid flow is not sufficient to enable the filter element 2 to be rotated by means of a propeller 4 or another suitable flow device 4, in a manner suitable for cleaning the filter element 2, Of course, it could also be possible and necessary to resort to energy sources (eg electric motors or power-driven machines, etc.).

[0027] For example, in the case of Sflo s, larvae seeds, meadows, etc., this value could be increased if so-called flight propagation (suction or pressure conveying) pneumatics Fb rd e tion, etc., and introduce the air into the filter. In order to increase the pressure effect, additional air or gas can be introduced here via an inlet, for example, by means of a pressure blower, as well as with hoses by means of a pressure pump. In the embodiment of the filter shown in FIG. 1, the filter element 7 and the filter element 2 are tubular. Naturally, all other conceivable geometric shapes are also suitable, for example a rectangular channel or the like suitable structures. In order to have a positive effect on the fluid flow, In addition, it may be useful to arrange a conical outlet 7a above the filter element, on the upper inner wall of which the propeller 4 is arranged. In this embodiment, the largest outside diameter of the cone-shaped outlet 7a preferably extends up to the inner circumference of the filter container 7. Furthermore, it is also possible to arrange a conical inlet below the filter element 2.

As can be seen from Fig.l, the filter element is mounted on the bearings 5, welc hey are arranged on plates 8.

2 shows a device 10 for the purification of exhaust air, waste water and / or process gas streams with a plurality of filters 1, which are arranged in series in the illustrated embodiment. Moreover, devices 10 can also be designed such that the filters 1 are arranged in cascade or in any conceivable way in a group. In this embodiment, it would be conceivable to carry out the filtration directly on the inmissio nso, ie without having to use a central filter, and thus to immediately return the "filter cake" to the production cycle (saving of raw materials), but also to create combinations by using a so-called "filter cake" In addition, individual filtration (and / or cascade filtration) is provided, so that individual particles (depending on the size of the particles) can be filtered out and returned to the process cycle before the so-called cleaning of the medium to be filtered takes place. [0031] The device 10 has a raw fluid inlet channel on the underside 9a and on the upper side a clean fluid outlet channel 9b Below the filter housing 1 surrounding device housing 11 there is provided a collecting container 12 in which the product of separation is collected (filter cake) The filters 1 according to the invention are the same here as in the embodiment of FIG e sta lte t. [0032] In a further embodiment of the invention, the housing can also be returned directly to the process stream and / or the process cycle, using the paper as a high-fidelity filter or within a green arrangement.

[0033] In another embodiment of the invention, shown in FIG. 3, the flow does not affect them, which are disposed within the pus member 2 on the inner wall thereof. In another embodiment of the invention, the above devices 4 and embodiments of the parent 1 may preferably also be combined with one another. It is conceivable that excess energy, which is captured by the propeller 4, may be stored by a generator or made useful elsewhere.

The inventive EQterbe is limited insofar in its execution not on the above-mentioned preferred embodiment sformen. Rather, a variety of design variations are conceivable, which make use of the illustrated solution even with fundamentally different type of execution.
