METHOD OF GAS DEDUSTING AND IMPLEMENTATION DEVICE Russian patent published in 2008 - IPC B01D50/00 B04C3/06 

FIELD: process flows, filters.

SUBSTANCE: invention is related to dry dedusting of gases and can be applied in various industries, primary in metallurgy industry. Dust-laden gas from dust release sources is fed to direct-flow dust-arresting device via gas pipelines with valves and fitting of axial feed of dust-laden gas. Gas is whirled in guiding axial device upstream the separation chamber and dust is rejected to the hopper via window in separation chamber. Preliminary purified gas is fed to fine gas filter to filter gas, divert purified gas and unload dust resulted after fine gas filtering. Moreover dust-laden gas is additionally fed to direct-flow dust-arresting device, which is installed upstream the separation chamber at discharge of the guiding axial device, via guiding device for tangential feed of dust-laden gas where gas is whirled in the direction same as in the guiding axial device. Rejection of dust to hopper from separation chamber is performed in tangential direction through the window in form of slot port provided lengthwise the separation chamber for tangential rejection of dust.

EFFECT: increased efficiency of gas purification, primary of dust-laden gas from several dust release sources.
