The present invention relates to an improved flow-through device, for example, to filter contaminants from a gas or liquid for drying gas, for separating condensate from the gas, etc.

Such flow-through devices of this type consist basically of a housing in the form of a container with a lid which is provided with an inlet and outlet for the fluid, and a removable tubular flow element provided in the housing, which is provided with a substance for treatment of the fluid, and this element is installed at the cover and forms a partition between the cavity inside the element, which is connected with the inlet and the cavity on the outside of the element, which is limited by the housing and which is connected with the release.

The raw fluid is directed through the inlet and the cavity inside the element through the element, resulting in, for example, in the substance of the element remain contamination or condensation, after which the fluid medium is output as the processed fluid medium through the cavity from the outside of the element and release for further use.

A disadvantage of the known flow-through device is that, flowing through the element, fluid is not evenly distributed across the entire length of the element, and the main part of the spent fluid is consumed only through the portion of the element, namely the part that is closest to the inlet is.

This is disadvantageous, because the rest of the element is used less efficiently, and the pressure loss element is relatively large, because the flow is pumped only through a limited portion of the element. Pressure loss mainly depends on the local velocity, which grows in the discharge flow through a smaller area.

From the document WO 2004/009210 already know the possible improvement in the form of a short tube, which is provided in the center in the continuation of the inlet and has a diameter that is smaller than the diameter of the inlet, to make part of the spent stream, flowing through a short tube, situated a little further from the inlet of the cavity inside the element.

However, this solution is still not enough and still disadvantageous because fluid is not evenly distributed across the length of the element, and the fact that some areas of the substances are used less efficiently than other zones.

The present invention aims at mitigating the above-mentioned and other disadvantages.

Therefore, the invention relates to a flow device of the above type, and in the cavity inside the element opposite the inlet provided by the tube, which takes place mainly in the axial direction of the element and which is provided with side channels for uniform distribution of fluid, odiada processing, the length of the flow-through element, and this tube has a cross section tapering in the longitudinal direction in the axial direction of the fluid flow through the tube and the cavity on the outside of the element connected with the issue through the channel in the annular flange of the cover.

Fluid to be processed, distributed along the length of the element through a narrowing tube through the channels, resulting substance element is used more efficiently, which can result in loss of pressure can be reduced by up to 30%.

In addition, such a tube it is possible to realize a simple and cheap way, thus limiting the cost of such improved flow-through device.

The invention also relates to a flow element containing the tube cross-section, tapering in the longitudinal direction, which is provided with side channels and can be used in flow-through device in accordance with the invention.

In order to explain features of the invention, only as an example, in no way restrictive, and with reference to the accompanying drawings, provides the following preferred implementation of an improved flow-through device in accordance with the invention, with

figure 1 presents with the increase of an improved flow-through device in accordance with the invention;

figure 2 presents a portion indicated by symbol F2 in figure 1;

figure 3 presents a perspective view of a part indicated by F3 in figure 1;

4 shows a variant of the device according to figure 1.

The flow-through device 1 represented in figure 1-3, is composed mainly of a housing in the form of the vessel 2 with a cover 3 which is provided with an inlet 4 and release 5 for the fluid and interchangeable tubular flow element 6 provided in the housing.

The flow-through element 6 provided with a substance 7 for processing the fluid, and this substance 7, for example, consists of a filtering material, which is suitable for delay dirt or condensate drops, or desiccant to remove moisture from the current environment to be processed, or catalyst, or other active or passive components.

In the above example, the substance 7 is a variation of a filter cloth provided around the bearing porous or perforated tube 8 of the element 6, and the substance 7 can also rely between two concentric porous or perforated pipes so that the substance 7 will be supported along each side.

Element 6 in this case provided at its top of head 9, is made of plastic or similar material, which is above what Riske 3 and installed it so, that forms above the inlet 4 and release 5.

Above the head 9 element 6 is provided with a curved guide tube 10 with the annular flange 11, which is held in the cover 3 by means of a radial bearing ribs or similar means, and this guide tube 10 is connected with an internal cavity 12 one far end with the inner side of the element 6 and installed the other far end of the hook in the socket 13 of the cover 3, and the pipe 13 is threaded 14 due to the connection of the feeding tube for the fluid to be processed.

The element 6 has its lower end on the bottom 15 of the container 2 of the housing and thus forms a partition between the above cavity 12 inside the element 6, which is connected with the inlet 4, and the cavity 16 from the outside of the element 6, which is limited by the element 6 and the housing and which is connected with release 5 through channel 17 around above the ring support 11, and this release 5 opens into the pipe 18, which is threaded 19 due to the connection of the discharge tube for processed fluid medium.

The channel 17 is preferably large enough not to cause any additional pressure losses.

On the lower side of the vessel 2 is provided another opening, which is not shown in the drawings and through which dirt and drops of condensate which can be removed through the drain under the filter element, which can be opened manually or automatically, in order to release the flow of condensate out.

In accordance with the invention in the cavity 12 within the element 6 opposite the inlet 4 is provided by the tube 20, in the example conical tube, which is not part of the flow element with the cross-section, tapering in the longitudinal direction, which takes place mainly in the axial direction x-X' of the element 6 and which is provided with side channels 21.

The tube 20 is attached to the above-mentioned cylinder 9 with its wide end by gluing multiple mounting protrusions 22, which are first clamped in the groove 23 provided in the head 9 of the element 6. The rest of the element 6, i.e. the filter cloth 7 and the supporting tube or bearing tube 8 while also glued in the groove.

Alternatively, the tube 20 can also be attached to its wide end to the extreme inside of the perforated tube 8 by welding the securing tabs 22 on the inside of the tube 8.

All this construction, consisting of a tube 8 and the tube 20 can then be glued in the groove 23 of the head 9 with the filter cloth 7 and the potential of the outer perforated tube.

Conical tube 20 forms, so to say, a continuation of the inlet 4 or, in particular, the guide tube 10.

Side channels 21 preferably the distribution is received in accordance with an ordered pattern on the circumferential surface of the tube 20 and they open in a cavity 12 within the element 6 at different distances from the inlet 4.

Channels 21 can have various forms, such as cracks, which are mainly in the longitudinal direction of the element 6.

In the embodiment according to figures 1 to 3, the tube 20 extends only part of the length L of the element 6, preferably on the length of M in the range between 1/3 and 4/5 of the length L of the element 6, or in the best case, is in the range from 40% to 70% of the length L of the element 6.

In this case, the tube 20 is open at its narrow end forming an axial outlet 24, the diameter of the outlet 24 is preferably in the range from 20% to 50% of the diameter of the wide end of the tube 20, and preferably is of the order of magnitude of 40% of the diameter of the wide end.

The work of an improved flow-through device 1 in accordance with the invention is simple and as follows.

Fluid to be processed is fed into the flow-through device 1 through the inlet 4 in the direction of the arrow I and is directed by the conical tube 20 through the guide tube 10.

The flow of the fluid to be processed is blown into the cavity 12 through the side channels 21 and through the axial outlet 24, as represented by the arrows shown in dotted lines in figure 2.

Thus, the fluid to be processed is uniformly distributed over the entire length L of the element 6 and is pumped into the internal cavity within the element 6 with the em static pressure passing further through the substance 7 of the element 6 to the outside of the element 6.

Then, the processed fluid is collected in the cavity 16 from the outside of the element 6 and is available through the holes 17 and issue 5 in the direction of the arrow On for further use or processing.

There are two reasons why such a flow-through device 1 in accordance with the invention has a lower pressure drop and is more efficient in operation.

On the one hand, the static pressure in the cavity 12 within the element 6 is distributed more evenly, which contributes to a more uniform distribution of flow over the entire length L of the element, as this static pressure is the driving force that pushes the fluid through the substance 7 item 6.

On the other hand, fluid is blown deeper into the element 6 in the axial direction x-X', which is also conducive to a better distribution of the fluid flow along the length L of the element 6 and leads to a smaller pressure drop in the flowing device 1.

Through the use of a tapered tube 20 can reduce the pressure drop on flow-through device 1, at least 10% or, depending on the application, you can even reduce the pressure loss of at least 20% or more - 30%.

Depending on the shape and dimensions of the flow-through device 1 and characteristi 7 you can optimize the effect of a tapered tube 20 by selecting the correct form, size and position for conical tube 20, as well as the correct number and position to the side channels 21, as well as the correct shape and dimensions of the axial outlet 24.

4 shows a preferred variant implementation, the tube 20 in this case runs along the entire or substantially the entire length L of the element 6 and the conical tube 20 in this case is pointed and closed at its narrow end.

Obviously, a conical tube 20 can be made of various materials, although it is preferable to stainless steel or plastic.
