Abstract: This invention relates to filtering dust or smoke-laden gases that contain dust particles by use of a pocket or bag-filter, in which, depending on the characteristics of the dust, the dust filtered out in the filter is extracted therefrom in quantities corresponding approximately to 2 to 100 times the proportion of dust arriving per unit of time in the gas to be filtered. This agglomerates the fine dust which is then continuously fed back to the incoming dust-laden gas prior to, or in, the filter. Thereafter, a quantity of incident dust is removed from the filter, this quantity corresponding to the amount of dust contained in the dirty gas per unit of time.In accordance with this invention, a chemical additive substance is fed to the dust which is to be fed back continuously in circuit to the filter and which is incident on or is to be agglomerated in the filter, said substance being capable of reacting with any chemical contaminants contained in the dust-laden gas so as to form filterable substances. The chemical additive may be in the form of a powder or suspension and may be an oxide or hydroxide of an alkaline metal, an alkaline-earth metal or aluminum.

Abstract: A filtering separator with a reverse-flow cleaning apparatus has a chamber that travels inside the clean gas area and is provided with a compressed air supply line plus at least one injector. The chamber is divided into a suction area for the drawing in of secondary flush gas and a pressure area. In the wall of the suction area of the chamber there are provided openings with check valve-like blocking elements for the drawing in of the secondary flush gas from the clean gas area. Compressed air injectors may be provided in the clean gas air in front of these blocking elements to assist opening them. A wall of the chamber adjacent to the filter element section of the filter separator may be made of a flexibly bendable material and may further be provided with inflatable hollow bodies in its edge regions to allow the chamber wall to conform to the wall dividing the crude gas air from the clean gas area of the separator.

Abstract: Within its dust gas space, the stratified bulk material filter receives the layers of bulk material which are bordered at either side by delimitations, may be traversed transversely by a flow of flue gas or dust gas, and which are combined in pairs to define a purified gas flow departure space connected to the purified gas side, situated between them. Upon installing the bulk material layer delimitations, the delimitations are first inserted into the dust gas space from the purified gas side at the flow arrival side of the bulk material layers and are immovably suspended therein on bearers of the end sides of each pair of bulk material layers, whereupon gas-permeable delimitations are inserted from the purified gas side to establish the delimitations at the flow departure sides and are suspended by their extremities on the end sides of each pair of bulk material layers, then the spaces between the delimitations at the flow arrival and flow departure sides are charged with bulk material.

Abstract: A gas dust-removing or dedusting filter of the kind incorporating a filter casing, filter tubes or bags having a flattened oval cross-section, and internal spacing elements. The casing includes a vertical partition having perforations and dividing the casing into a pure or clean gas chamber and a gas dust-removing chamber. The tubes or bags are horizontally insertable into the dust-removing chamber through the perforations of the partition and are sealed at their open ends to the clean gas side of the partition while their closed ends are supported on the rear wall of the casing.In accordance with the invention, parallel vertical guide members, each having a surface which slopes with respect to a rear wall of the casing, are secured to the inner side of the rear wall of the casing. One guide member is disposed between two adjacent filter tubes or bags. The filter tubes or bags rest on support bars adjacent the rear wall of the casing, which engage said guide members. Also, the projection of each sloping surface on the rear wall corresponds to the spacing between two adjacent filter tubes or bags. The guide members prevent or minimize twisting of the tubes or bags.

Abstract: The invention relates to a cooler for hot smoke-laden gases which are to be cleaned by a pocket or tube filter situated in a downstream location. The cooler has a housing provided with cooling elements through which cold external air is conducted perpendicular to the direction of flow of the smoke-laden gas. The cooling elements are loose tubes of generally oval shape which project through perforations in two opposing walls of the cooler housing. Associated with each end of each cooling tube outside the cooler housing is an annular flange, which, by means of at least one spring presses an annular gasket situated between itself and the outer wall into the annular gap between the cooling tube and the perforation in the wall of the housing.

Abstract: A filtering separator, in particular a pocket or tube filter, of the kind in which smoke-laden gas containing dust particles of particularly great adhesiveness is fed into a dust collecting trough of a filter housing at the bottom and upwards towards filter elements and in which the filter elements are cleaned periodically by counter-current scavenging and/or joggling. A proportion of the settling dust agglomerated in the filter which corresponds to the amount of dust in the incoming smoke laden gas and which cannot be carried back to the filter surfaces by the smoke-laden gas is removed from said dust collecting trough.A lower part of the dust collecting trough is occupied by a longitudinally extending, rotatably mounted, perforated or sieve-like drum which is arranged to be filled with heavy bodies such as balls. The upper part of the drum is exposed and acts as a dust-collecting store or reservoir to which the smoke-laden gas is fed in order to flow transversely through the drum and its contents. At the end or below the drum there is provided an exit opening to allow the dust to drop out of the collecting trough. This opening contains a compartmented dust removal device which, together with the drum, can be set in rotation as soon as the resistance to flow through the drum reaches a maximum and which is stopped when a minimum is reached.
