Abstract: A dry filter 1 to be used in particular in underground mining and tunnel construction having a frame construction 17 into which the required part housings 25-28 can be inserted from the side. The required partition wall 8 is arranged so that an optimal large filtering surface is available both for the incoming raw gas and for the outflowing clean gas. Raw gas duct 5 and clean gas duct 6 run horizontally one above the other and are separated from each other by the sloping 8. This means that a very large filtering surface is available.

Abstract: A wet scrubber 1 with a low energy requirement, i.e. with reduced throughflow resistance has a demister 5, whose filter package 25 is shaped corrugated or folded. This makes a large surface available to ensure reliable soaking of the inflowing dust. Further advantages are a sloping bottom plate 15 in the demister part housing 4, specially positioned and designed moistening nozzles 6, 7 as well as above all a partitioning of the demister 5 into several complete packages 31, 33.

Abstract: The invention related to dust filters (1) which are especially used in operations endangered by gases and comprise filter elements (10) rendered antistatic by means of derivative constituents such as carbon fibres, salts or special steel fibres (26, 27). The filter material (10) is connected to the housing frame (14) by use of conductors (16), bypassing the seal (15), in such a way that a negative electrical charge of the inner chamber of the individual filter element (10) or the dust filter (1) is avoided.

Abstract: A dedusting device 1 with a demister 15 advantageously arranged standing obliquely has a very compact construction because sufficient moistening or wetting of dust-containing crude air 24 is possible through the use of intensively acting multiple stream nozzles 33. The ventilator 11 is allocated to its own ventilator housing 18 that is connected to the dedusting device housing 10 and has a muffler 20 inserted downstream.

Abstract: For purifying dust-containing air, particularly in underground mining and tunnel construction, a dust separator 1 in the form of a rotary washer 1 is proposed. The drive 5 of said rotary washer 1 is equipped with a gear unit 10 in order to enable long-term operation with a straight characteristic. Furthermore, disposed downstream of the fan impeller 6 is a special separating element 11 in the form of a demister 20, which is disposed so as to be suspended approximately horizontally in the air stream. Clogging of the demister 20 is therefore effectively prevented and so uniform and reliable operation is guaranteed. The demister 20 together with its associated jetwashing device 22 may be swivelled by a positioning motor 23 into an, in each case, optimum position.
