INDUSTRIAL DUST-GAS CLEANING LINE Russian patent published in 2018 - IPC B01D46/02 

FIELD: machine engineering.

SUBSTANCE: industrial dust-cleaning line comprises bag filters made with wrapped tubular shells of filter material with frame filter elements in the dust-collecting chambers of each bag filter, a contaminated air inlet duct communicating with chamber receivers of the dust-collecting chambers, in which the frame filtering elements with their open ends are extended into the chambers of cleaned air which and communicated with air duct of the cleaned air outlet. In cleaned air chambers there are pipelines with pulse tubes, which are located opposite the outlet holes of filtering hoses for impulse regeneration of these hoses by compressed air. The bag filters are installed in at least two linearly arranged rows. The contaminated air inlet duct is provided with common inlet branch pipe and divided into hoses, each of which communicates with each chamber receiver of the dust-collecting chambers of one row of bag filters. Each filter element consists of metal lattice frame with one blind end and fabric tubular shell made of filter material and stretched on this frame. In each vertically oriented main dust-collecting chamber, the filter elements are arranged horizontally in rows horizontally and vertically with extension of their open ends vertically oriented along the main dust-collecting chambers of the cleaned air chamber. The pipelines with pulse tubes are mounted vertically with the location of each pulse tube opposite the open end of the corresponding frame filter element. The air duct of the cleaned air outlet from the chambers of the cleaned air is made in the form of two hoses, which are extended under the cleaned air chambers of each row of bag filters, and connected to the lower parts of the cleaned air chambers and communicated with the common outlet branch pipe.

EFFECT: improvement of efficiency and reliability.
