Abstract

In order to provide a filter system for separating off contaminants from a stream of untreated gas that contains contaminants that is of simple construction and is operable efficiently, it is proposed that the filter system should include the following: a base construction through which the stream of untreated gas is guidable and which includes at least one filter module receptacle for receiving at least one filter module, and at least one filter module which is selectively arrangeable on and/or in the at least one filter module receptacle and/or removable therefrom, wherein the at least one filter module includes a plurality of filter element receptacles for receiving a plurality of mutually independent filter elements.

First claim

The invention claimed is:

1. A filter system for separating off contaminants from a stream of untreated gas that contains contaminants, including
a base construction through which the stream of untreated gas is guidable and which includes at least one filter module receptacle for receiving at least one filter module, and
at least one filter module which is selectively arrangeable on and/or in the at least one filter module receptacle and/or removable therefrom,
wherein the at least one filter module includes a plurality of filter element receptacles for receiving a plurality of mutually independent filter elements,
wherein at least one filter module receptacle is arranged on an outer wall of the base construction and/or is integrated in the outer wall of the base construction, and wherein at least one filter module is arrangeable on the at least one filter module receptacle, by bringing the at least one filter module into abutment against the outer wall,
wherein the at least one filter module receptacle and the at least one filter module each include an inlet opening and an outlet opening, such that both the inlet opening and the outlet opening of the at least one filter module are arranged on a front side of the filter module;
wherein both the inlet opening and the outlet opening of the at least one filter module receptacle extend through the outer wall on which the filter module receptacle is arranged; and
wherein the outlet opening of the at least one filter module receptacle at least partially overlaps with the inlet opening of the at least one filter module and the inlet opening of the at least one filter module receptacle at least partially overlaps with the outlet opening of the at least one filter module so that the stream of untreated gas flows from the base construction into the at least one filter module, where it is treated, and then flows back out of the at least one filter module into the base construction as a stream of treated gas.

2. The filter system according to claim 1 , wherein a plurality of filter elements are a constituent part of a filter device of the filter module and the stream of untreated gas that is to be cleaned is flowable through these in mutually parallel manner during a filter operation of the filter system.

3. The filter system according to claim 1 , wherein the at least one filter module includes a plurality of filter devices and the stream of untreated gas that is to be cleaned is flowable through these one after the other during a filter operation of the filter system.

4. The filter system according to claim 1 , wherein the at least one filter module includes a pre-filter device, a main filter device and/or a post-filter device, and at least a partial stream of the stream of untreated gas is flowable through these one after the other during a filter operation of the filter system.

5. The filter system according to claim 1 , wherein the at least one filter module and/or the at least one filter module receptacle includes a guide device for guiding, moving and/or immobilising the at least one filter module in relation to the at least one filter module receptacle.

6. The filter system according to claim 1 , wherein the base construction includes at least one closable access opening through which an interior space of the at least one filter module receptacle is accessible for introducing and/or removing the at least one filter module from outside the filter system.

7. The filter system according to claim 1 , wherein the filter system includes a plurality of filter module receptacles arranged opposite one another in relation to a vertical longitudinal centre plane of the filter system, and/or a plurality of filter module receptacles arranged successively in a longitudinal direction of the filter system.

8. The filter system according to claim 1 , wherein the filter system includes a plurality of filter module receptacles that form flow channels of the filter system which are configured for mutually independent through flow, wherein individual or a plurality of flow channels are blockable or clearable by means of valve devices of the filter system.

9. The filter system according to claim 1 , wherein the filter system includes at least one untreated gas shaft that extends between at least two filter module receptacles and through which the stream of untreated gas is guidable and is feedable to inlet openings in the filter module receptacles.

10. The filter system according to claim 1 , wherein the filter system includes at least one clean gas channel that extends between at least two filter module receptacles and through which a stream of clean gas, which is obtainable as a result of separating off contaminants from the stream of untreated gas, is guidable away.

11. The filter system according to claim 1 , including at least one filter element receptacle for receiving at least one filter element and at least one change-over device for automatically exchanging a more pronouncedly contaminated filter element that is arranged in the at least one filter element receptacle for a filter element that is less pronouncedly contaminated.

12. The filter system according to claim 1 , wherein the filter system includes one or more filter modules and a collecting channel, to which a stream of clean gas obtainable by cleaning the stream of untreated gas is feedable from the one or more filter modules, wherein the collecting channel is arranged above the one or more filter modules, in particular directly over the one or more filter modules.

13. The filter system according to claim 1 , wherein the filter system includes one or more filter modules that include a pre-separating device, wherein if necessary the pre-separating device is arrangeable on the filter module, and/or wherein the pre-separating device includes an inertial filter or labyrinth filter.

14. A painting system for painting workpieces, in particular vehicle bodies, including at least one filter system according to claim 1 .

15. A method for separating off contaminants from a stream of untreated gas that contains contaminants by means of a filter system, including:
feeding the stream of untreated gas to a plurality of filter elements that are arranged in filter element receptacles of a filter module, wherein the filter module is arranged on and/or in a filter module receptacle of the filter system, wherein the filter module receptacle is arranged on an outer wall of a base construction and/or is integrated in the outer wall of the base construction, and wherein the filter module is being arranged on the at least one filter module receptacle by bringing the filter module into abutment against the outer wall, the at least one filter module receptacle and the at least one filter module each include an inlet opening and an outlet opening, such that both the inlet opening and the outlet opening of the at least one filter module are arranged on a front side of the filter module; wherein both the inlet opening and the outlet opening of the at least one filter module receptacle extend through the outer wall on which the filter module receptacle is arranged, wherein the outlet opening of the at least one filter module receptacle at least partially overlaps with the inlet opening of the at least one filter module and the inlet opening of the at least one filter module receptacle at least partially overlaps with the outlet opening of the at least one filter module so that the stream of untreated gas flows from the base construction into the at least one filter module, where it is treated, and then flows back out of the at least one filter module into the base cons
