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 takes the form of a rollable and/or displaceable transport carriage and 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 the base construction comprises an untreated gas shaft to guide untreated gas to the at least one filter module,
wherein the at least one filter module and a collecting channel for collecting clean gas are connected by at least one clean gas channel,
wherein the at least one filter module and the collecting channel are positioned on opposite sides of the untreated gas shaft.

2. A filter system according to claim 1 , wherein the collecting channel is arranged substantially at the same level, in relation to a vertical direction, as the at least one filter module.

3. A filter system according to claim 1 , wherein the at least one clean gas channel passes through the untreated gas shaft.

4. A filter system according to claim 1 , wherein the at least one clean gas channel has untreated gas flowing around it during operation of the filter system.

5. A 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.

6. A 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.

7. A 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.

8. A 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.

9. A 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.

10. A filter system according to claim 1 , wherein the filter system includes a plurality of filter module receptacles arranged successively in a longitudinal direction of the filter system.

11. A 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.

12. A filter system according to claim 1 , 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 in that 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.

13. A filter system according to claim 1 , wherein the filter system includes 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 of the at least one filter module for a filter element that is less pronouncedly contaminated.

14. A 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.

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

16. 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 through a untreated gas shaft to a plurality of filter elements that are arranged in filter element receptacles of a filter module, wherein the filter module takes the form of a rollable and/or displaceable transport carriage and is arranged on and/or in a filter module receptacle of the filter system;
separating off contaminants from the stream of untreated gas at the filter elements in order to obtain clean gas and guiding the clean gas through at least one clean gas channel to a collecting channel, wherein the at least one filter module and the collecting channel are positioned on opposite sides of the untreated gas shaft;
removing the filter module from and/or out of the filter module receptacle;
exchanging one or more of the more pronouncedly contaminated filter elements arranged in the filter element receptacles for one or more less pronouncedly contaminated filter elements;
arranging the filter module on and/or in the filter module receptacle.
