HIGH-TEMPERATURE DEVICE FOR REMOVAL AND FILTRATION OF DUST, HIGH-TEMPERATURE SYSTEM FOR REMOVAL AND FILTRATION OF DUST AND METHOD FOR CONTINUOUS REMOVAL AND FILTRATION OF DUST Russian patent published in 2019 - IPC C10K1/02 C10G1/00 C10B53/06 C10B53/02 B01D51/10 B01D46/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to filtration of oil gas and removal of dust during coal pyrolysis (coking), as well as to high-temperature device and system for removal and filtration of dust and method of continuous removal and filtration of dust for coal gas. Device comprises a set of high-temperature installations for removal and filtration of dust, as well as device (2) pre-heating and device (3) of regeneration, provided for high-temperature installations for removal and filtration of dust. System comprises two or more sets of high-temperature installations for removal and filtration of dust, as well as device (2) of pre-heating and device (3) of regeneration, provided for high-temperature installations for removal and filtration of dust. Method envisages availability of two or more sets of high temperature installations for dust removal and filtration, as well as pre-heating device (2) and regeneration device (3) provided for high-temperature installations for removal and filtration of dust. At the same time the method is implemented by means of high-temperature system for removal and filtration of dust, which is made with possibility of switching, which always supports one or more sets of high-temperature plants for removal and filtration of dust in normal state of filtration.

EFFECT: preventing coking of gaseous resin in micropores of filter cake and filter elements, as well as restoring gas permeability of filter elements.
