For device for the dust removal of the turntable gas

Abstract

The invention relates to a device ( 8 ) for dedusting converter gases, comprising at least one housing ( 9 ) with a circular cross-section, in which housing one or more devices capable of being removed from the converter are arranged Filter elements ( 18 ) through which gas flows, each housing having at least one feed line ( 15 ) for converter gas into the housing, wherein the feed line is opposite to the housing The operating state of the body opens into the housing ( 9 ) below the filter element ( 18 ) in such a way that a largely radial flow initially forms in the housing. In order to reduce the velocity peaks when the converter gas flows into the housing, provision is made here for the feed line ( 15 ) to end at the housing ( 9 ) and to form an elongated inflow opening ( 16 ) there, The inflow port has a larger size in the circumferential direction of the casing (9) than in the height direction (17) of the casing, wherein the inside of the casing (9) is connected with the inflow port (16) inside. There are no flow-guiding internals between the filter elements (18).

Description

technical field [0001] The invention relates to a device for dedusting converter gases, comprising at least one housing with a circular cross-section, such as a cylindrical housing, in which one or more housings are arranged Filter elements through which the converter gas can flow through, each housing having at least one supply line for the converter gas which leads into the housing, wherein the supply line operates relative to the housing The state opens into the housing below the filter element in such a way that a largely radial flow initially forms in the housing. [0002] A “filter element” here means a mechanically filtered element through which a gas flows, wherein the dust contained in the gas is deposited on the filter element. For each housing, usually a plurality of filter elements, the upper and lower ends of the filter elements are usually in a horizontal plane, respectively. [0003] The feed line opens into the housing in such a way that the fluid flowing int...

Problems solved by technology

[0012] However, for filters with ceramic filter elements, there is also the problem that velocity peaks can occur when the converter gas flows into the housing, which can damage the filter element

In addition, such velocity peaks can lead to turbulence in the funnel-shaped region of the housing below the inflow opening, whereby the dust that has been separated and deposited there is kicked up again and this previously separated The dust has to be separated by passing through the filter element again or this dust additionally loads the filter element by abrasion and can shorten the service life of the filter
