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

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.

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 takes the form of a rollable and/or displaceable transport carriage.

6 . 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.

7 . 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.

8 . The filter system according to claim 1 , wherein the at least one filter module receptacle includes at least one valve device for selectively opening or closing an inlet opening of the filter module receptacle, through which at least part of the stream of untreated gas is feedable to the filter module receptacle, and/or an outlet opening of the filter module receptacle, through which a stream of gas is guidable away from the filter module receptacle.

9 . 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.

10 . 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.

11 . 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.

12 . 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.

13 . The 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.

14 . A filter system for separating off contaminants from a stream of untreated gas that contains contaminants, in particular 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.

15 . A filter system for separating off contaminants from a stream of untreated gas that contains contaminants, in particular according to claim 1 , including:
a base construction through which the stream of untreated gas is guidable; and a fire protection device by means of which a fire in the filter system is preventable, containable and/or extinguishable, wherein the fire protection device includes one or more fire protection elements for affecting propagation of the flames.

16 . The filter system according to claim 15 , wherein the fire protection device includes one or more fire protection elements that are actuable in the event of a fire.

17 . The filter system according to claim 15 , wherein one or more fire protection elements include a fire-retardant material or are formed from a fire-retardant material.

18 . The filter system according to claim 15 , wherein one or more fire protection elements include a material or are formed from a material which, under the effect of heat and/or in contact with a reagent, is disintegrable, liquefiable and/or combustible.

19 . The filter system according to claim 18 , wherein the one or more fire protection elements are arranged, in an initial position, on one or more receptacles for one or more fire protection elements, and in that, by comparison with a material of the one or more receptacles, the material of the one or more fire protection elements has a lower melting point, a lower fire resistance and/or a lower chemical stability and/or physical resistance.

20 . The filter system according to claim 15 , wherein one or more extinguishing openings in the filter system are clearable in the event of a fire by means of one or more fire protection elements.

21 . The filter system according to claim 20 , wherein the one or more extinguishing openings of the filter system are cutouts or apertures in one or more walls of the filter system that are closed in normal operation of the filter system by means of one or more fire protection elements.

22 . The filter system according to claim 15 , wherein the filter system includes one or more filter elements and/or one or more filter modules whereof the interior space is accessible from outside in the event of a fire, by removing one or more fire protection elements.

23 . The filter system according to claim 15 , wherein the fire protection device includes an application device by means of which an extinguishing material and/or a reagent is dischargeable.

24 . The filter system according to claim 23 , wherein an extinguishing material and/or
