Definitions
- the invention relates to a filter device with a plurality of filter elements, which are accommodated in a filter housing with a filter inlet for a fluid to be filtered and a filter outlet for the filtered fluid, wherein the filter elements for filtration or backwashing are flowed through in both directions and at the same time at least a filter element performs the filtration and at least one other filter element for cleaning its effective filter surface is backwashed by means of a backwashing, which includes a pressure control device to assist the backwashing, having a pressure control element, by means of which in a backwash the fluid flow in a fluid connection between the filter inlet and the abrein to Filter element is controllable.
- a filter device of this type is known from EP 2 207 609 B1.
- conically shaped filter elements are provided, in particular in the form of so-called. Spaltsiebrohrfilter instituten. Due to the conical design, the distance between the individual conical Spaltsiebrohrfilter instituten is partially enlarged, with the result that also the outflow in the filter housing is increased. Even when backwashing the conical filter element is compared to a cylindrical clearly in the advantage.
- One reason for this is the relatively larger exit cross section of the conical filter elements at the lower end with respect to cylindrical filter elements with the same filter surface, because the larger outlet cross-section at the lower end favors the discharge of entrained with the backwash fluid contaminants.
- the pressure control element of the pressure control device which controls an unfiltrate flow to the backwash filter element for the assistance of the backwash, is assigned to the upper, open end of the relevant filter element, which has the smaller opening cross section corresponding to the conicity. Accordingly, in the known device, the filter inlet for the supply of the unfiltered material is located above the filter elements, so that during filtration the non-filtrate flows into the filter cavities via the openings having the smaller opening cross-section, which is not optimal with regard to the flow resistance.
- the invention is based on the object of providing a filter device which is characterized by improved flow properties during operation. According to the invention this object is achieved by a filter device having the features of claim 1 in its entirety.
- a significant feature of the invention is that the fluid connection between see filter inlet of the filter housing and each filter element to be cleaned has a connection space with element openings, each with an open end of the raw side forming the filter cavity each of a filter element in Can be brought connection that a fluid path is provided, flows through the unfiltrate in the filtration during the filtration in the connecting space, and that the passage of unfiltered through the element to be cleaned by the filter element element opening through the Pressure control element is controllable such that, as far as in the known device is the case, a backwashing favoring suction on the raw side of the filter element to be cleaned off is generated.
- the unfiltered material does not reach the upper ends of the filter cavities with the relatively smaller opening cross-section due to an immediate connection of the filter inlet of the filter housing, but from the connecting space, which is connected with its element openings with the raw sides of the filter elements, eliminating the need Fi lter inlet of the housing to be arranged such that the filtration process, the unfiltrate flow passes through the openings of the smaller cross section in the filter cavities.
- the device according to the invention is particularly suitable for ballast water systems of ships to avoid the unwanted entry of
- the solution according to the invention also copes well with very long backwashes, as is customary in ships, and, ideally, the filter elements are cleaned at extremely low filtrate pressures.

Furthermore, the inflow of Unfiltrat be provided in the bypass line amplifying pump, which is optionally controllable such that for the initiation of backwashing a Unfiltratströmung corresponding intensity is available.
- each element opening of the connecting space is assigned its own pressure control element.
- a pressure control element associated with the element openings could be provided which can be moved by means of a displacement device in operative connection with the element opening of the respective filter element to be backwashed.
- the respective pressure control element is a pneumatically actuated shut-off valve.
- a compressed air supply can thus be used for the operation of the filter device, as it is often installed in the plants or buildings in which such filter devices are often used.
- the filter elements are arranged in the manner of filter cartridges, in particular in the form of Spaltsiebrohrimplantationn, standing in the filter housing and with the upper, open end of their forming the raw side in the filtration Fi lterhohlraumes with the element openings of the connecting space in connection, the fil - Close teretti with the open, lower end of its filter cavity to an inflow, in which opens for the supply of the unfiltered the filter inlet of the filter housing.
- the filter elements thus form, with their lower opening having the larger cross-section during the filtering process, the inflow opening for the unfiltrate flowing from the inflow space of the fi lter housing, while the lower opening of the respective filter element to be backwashed forms the outflow opening for dispensing the dirt.
- loading backwash fluid forms.
- at least one bypass line could also connect the inflow space to the connection space, preferably in parallel to the fi lter candles, in a fluid-conducting manner.
- the open, lower end of the filter cavity of each filter element to be cleaned is connectable to a backwash line through which the dirty fluid is discharged during backwashing, the backwash line is selectively lockable and releasable by means of a valve device.
