Device for separating gaseous fluids

The innovation relates to a device for separating gaseous fluids comprising, to form a separator surface, first and second profile parts that are open in cross-section and are channel-shaped and arranged at least in two opposite rows, wherein preferably the free longitudinal edges of the edges of the first profile parts overlap the free longitudinal edges of the edges of the second profile parts.

/ A corresponding separator device is EP-A 0 206 204

The profile parts themselves have, in addition to the channel-shaped structure, a projection in the apex area of the inner surface that runs in the direction of the profile part opening and along its longitudinal axis. This has the advantage that further chambers are formed to influence the flow rate of the fluids flowing through the separator. As a result, the degree of separation is unexpectedly greatly increased. Appropriate separator devices have led to optimal results in the cleaning of cooling fluids, oil mists, grease mists or, more generally, air containing dirt particles, so that there are almost unlimited application possibilities. Of course, the size of the separator surface must be

Profile parts arranged in rows are adapted to the flow rate. In some applications, however, the space available is limited, for example if existing facilities are to be retrofitted with appropriate separation devices or if there is only limited space available for new installations.

The purpose of the present innovation is to design a separator device of the type mentioned above in such a way that \_) even in limited spatial conditions large

Separator areas can be made available. The possibility should also be created to install compact, large-area separators in existing exhaust air systems.

The object is achieved according to the invention in that the device has a housing in which at least two separating surfaces are arranged at a distance from one another, and in that the housing has a fluid inflow and outflow opening, one of which runs outside and the other inside the space surrounded by the separating surfaces in the housing. Preferably, four separating surfaces form the side surfaces of a cuboid which is coaxial with the longitudinal axis of the housing, which is preferably also designed as a cuboid.

is arranged, wherein the edges of the cuboids preferably

&EEgr; 45° offset from each other. According to the innovation,

Accordingly, a separator device is proposed which has a

j channel housing in which coaxially the one

Enveloping separator surfaces are arranged, which

preferably from the outside through which the fluid to be cleaned flows.

To form the fluid inlet opening, the space surrounding the separator surfaces is preferably covered at the front, e.g. by an inflow cone, in order to avoid unnecessary resistance for the fluids flowing into the housing.

avoid uniformly loading the separator surface. In order to enable optimum cleaning of the fluids, the long axes of the profile parts run perpendicular to the long axis of the housing, which essentially coincides with the inflow direction of the fluid. If the separator device according to the invention is arranged horizontally or at an angle, there is the additional advantage that the particles separated in the profile parts flow downwards due to gravity, preferably into the area of abutting separator surfaces, where the separated contaminants are then removed by a collecting channel.

* The drain opening of the channel is located in the rear area of the housing, as the pressure gradient forces the separated particles into this area. The drain itself can have a siphon.

In a further embodiment of the invention, the separator surfaces are connected to a support element such as a support tube running coaxially to the longitudinal axis of the housing, which in turn is supported on the inner wall of the housing in a centerable and rotatable manner. This has the advantage that the body formed by the separator surfaces can be rotated in order to align a separator surface ■' with an inspection opening to the desired extent. This results in

the advantage that inspection and/or replacement or renewal of individual test parts is possible without removing the separator surfaces from the housing.

The separator device according to the innovation can be used in existing exhaust air duct systems without the need for complex conversion measures. The fact that ^the separator surfaces run in the direction of flow and are nevertheless perpendicularly or essentially perpendicularly flowed through by the fluids results in the advantage that the cross-sectional area of the housing through which the fluid flows must be considerably smaller than the required separator area in order to achieve a

Further details, advantages and features of the innovation arise not only from the claims, the features derived from them - individually and/or in combination - but also from the following description of an embodiment shown in the drawing.

Show it:

Fig. 1 is a side view of a device according to the invention for separating fluids with omitted housing walls and

Fig. 2 shows the device according to Fig. 1 in front view.

The figures show a device (10) for separating gaseous fluids, which has a housing (12) and separator surfaces (U), (16), (18) and (20) arranged in it. The housing (12) has a cuboid shape with open end walls designed as inlet openings (22) and outlet openings (24). The end edges of the housing (12) have flanges (20) and (28) in order to be installed, for example, in an existing ventilation system such as a ventilation duct.

The separator surfaces (14), (16), (18) and (20) consist of first and second profile parts that are open in cross-section and are channel-shaped and arranged in rows, with the free longitudinal edges of the edges of the first profile parts preferably overlapping the free longitudinal edges of the edges of the second profile parts. Furthermore, projections that run in the direction of the profile part opening and along its longitudinal axis can be arranged in the apex area of the inner surface, whereby on the one hand an additional chamber that influences the fluid flow speed is formed and on the other hand fastenings for holders are provided in order to receive the individual profile parts detachably, but with precise positioning. In other words, the profile parts that are arranged in rows and that form the separator surfaces (14), (16), (18) and (20) have a construction as can be seen, for example, in European patent application 0 206 204 and in particular in Figs. 1 and 2. Notwithstanding this specific embodiment, European Patent Application 0 206 204 represents a supplementary disclosure to the present description.

The profile parts (30), (32) are arranged in the housing (12) in relation to the flow direction indicated by the arrows (34) and (36) in such a way that their longitudinal axes run perpendicular to the longitudinal axis (38) of the housing (12) and thus to the flow direction. This ensures optimal penetration of the separator surfaces (14), (16), (18), (20) to effect cleaning.

In order to ensure that the separator surfaces (14), (16), (18) and (20) are not flowed around, i.e. cannot be bypassed, the interior (40) encompassed by the separator surfaces (14), (16), (18) and (20) is covered by a flow element such as a flow cone (42), whereby the fluids to be cleaned (indicated by the arrows (44) and (46)) are first guided along the inner wall (48) of the housing, in order to then pass through the separators formed by the profile parts (30) and (52).

surfaces (14), (16), (18) and (20). The then cleaned fluids enter the interior (AO) and then exit the housing (12) via the outlet opening (24).

In the area of the abutting profile surfaces, e.g. in the area of the connecting line (50), a collecting channel (not shown) can run in order to collect media separated in the separator surfaces Ü4), (16), (18), (20) which flow due to gravity to the collecting channel in the area of the line (50) and then drain them off via a drain opening which is arranged in the rear area of the housing (12), i.e. in the area of the outlet opening <24).

The separator surfaces (14), (16), (18) and (20) are connected with their unspecified profile strips which hold the holders for the profile parts (30), (32) to a support tube (52) which runs coaxially to the longitudinal axis (38) of the housing (12), which in turn is supported in a rotatable manner via length-adjustable tube elements (54), (56), (58), (60) on the inner wall of the housing, specifically in its corners. For this purpose, the tube elements (54), (56), (58) and (60) are designed to be length-adjustable with the aid of a counter-threaded sleeve (not specified in more detail) in such a way that the desired centering of the support tube (52) is guaranteed. The rotatability of the support tube (52) and thus of the separator surfaces (14), (16), (18), (20) makes it possible to design one side, in the example shown the side (62), as an inspection cover in order to check and/or replace existing profile parts (30), (32) in this area. This results in the significant advantage that it is not necessary to remove the separator surfaces (14), (16), (18), (20) during inspection work. Instead, only the separator surfaces (14), (16), (18), (20) need to be rotated towards the inspection opening (62) in order to be able to carry out the necessary work.

It should also be emphasized that devices can of course be provided through which moisture, hot air and/or liquids can be applied to the individual profile elements in order to dissolve and thus remove deposited particles such as salts or wax particles.
