Abstract: This invention relates to filtering separators of the kind having a housing which is subdivided by a partition, provided with parallel rows of holes or slots, into a dust-laden gas space for receiving filter elements positioned in parallel rows and being impinged upon by dust-laden gas from the outside towards the inside, and a clean gas space. In addition, the housing is provided with a chamber for cleansing the filter element surfaces of a row by counterflow action while covering at the same time the partition holes or slots leading to the adjacent rows of filter elements. The chamber is arranged for the supply of compressed air to at least one injector arranged to feed compressed air and secondary air to the row of filter elements to be cleansed. The chamber is also reciprocatingly displaceable along the partition in periodic and intermittent manner. According to the invention, a surface of the chamber facing towards the partition covers at least two of the rows of holes or slots of the partition, and the chamber is closed upon itself with respect to the clean gas space, and is connected to a compressed air reservoir via a distributor pipe and a control valve. At least one of the rows of holes or slots of the partition and the respective row of filter elements in flow communication therewith are in flow communication with the discharge side of at least one injector acted upon with compressed air. At least one other row of the rows of holes or slots of the partition and the respective row of filter elements is in flow communication with the suction side of the injector.

Abstract: A contact compartment for intermixing dust or fume laden gases with solid substances, in a turbulent or fluidized layer, the gases being the turbulence carrier, and the solid substances being the turbulence material. The intermixing action induces the noxious components of the dust or fume laden gases to absorptively react or combine with the solid substances and form absorption compounds. In order to prevent the conventional formation of inhomogeneous sections in the turbulent or fluidized layer, during the intermixing action, the turbulence material and turbulence carrier, present in the compartment, flow transversely through at least one revolving drum having a perforated peripheral wall and equipped with a charge of filled-in regular or irregular-shaped bodies.

Abstract: The housing of the stratified bulk material filter contains several vertical bulk material layers which may be traversed transversely by crude gas flow, and are enflanked at both sides by delimitations and which may be supplied with particulate bulk material from above.A periodically occurring flushing-gas counterflow flushing operation is optionally combined with lateral and/or bottom bulk material extraction, whereby an adsorption of noxious gases and/or separation of particles from the crude gas is resolved advantageously by appropriate selection of the possible combination, in a simple structure.

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: This invention relates to filter tubes arranged in a gas-dust removing filter apparatus, and adapted to be cleaned by counterflow scavenging. Such filter tubes are provided with a seal at the clean gas side of a perforated partition which subdivides the filter apparatus, containing the filter tubes, into a dust-removing chamber and a clean gas chamber. The seal includes a clamping frame to grip the rim of the open mouth of a filter tube in resilient manner between itself and the partition. The filter tubes, which are inserted into the dust-removing chamber by way of the perforations of the partition, are each provided with a rigid internal spacing element. Further, in accordance with the invention, the clamping frame is connected to a spring means which engages the spacing element inside a filter tube, and is placeable in a position to bear against the dust-laden gas side of the partition, when being stressed. The parts of the clamping frame and the structure of the spring means connected to the clamping frame, also support, at the partition, the confronting end of the spacing element which terminates in front of the partition.
