The invention provides a raw gas purification plant. The plant comprises a first cyclone separator, a thermal-insulation jacket and a granular bed deduster, wherein the first cyclone separator is provided with a raw gas inlet, a raw gas outlet and a first semicoke powder outlet; the thermal-insulation jacket is sheathed outside the first cyclone separator, and provided with a first hot medium inlet and a first hot medium outlet; the granular bed deduster is provided with a deduster gas inlet, a backflush hot gas inlet, a clean raw gas outlet and a second semicoke powder outlet; and the deduster gas inlet communicates with the raw gas outlet of the first cyclone separator. According to the plant, the first cyclone separator and granular bed deduster connected in series are used for carrying out dedusting treatment on the raw gas, so the dedusting effect is higher. Meanwhile, the thermal-insulation jacket and the backflush hot gas inlet arranged on the granular bed deduster are utilized to perform thermal insulation in the dedusting process, so the thermal-insulation effect is stable. In general, the plant has the advantages of simple structure, higher purification effect and stable temperature control.
Description
technical field [0001] The invention relates to the technical field of raw coal gas purification, in particular to a raw coal gas purification device. Background technique [0002] Among the traditional high-temperature raw gas purification devices, commonly used are ventilated ceramic tube (microporous ceramic and ceramic membrane) dust collectors, large bag type back-blowing dust collectors, off-line dust cleaning bag dust collectors, multi-tube cyclone dust collectors, water washing dust removal and purification device. However, there are some problems in the purification treatment of high-temperature raw coal gas in each purification device: [0003] Although the filtration effect of the ceramic tube dust collector is satisfactory under high temperature conditions, as the dust removal time prolongs, the pores of the ceramic tube (membrane) will be blocked, making regeneration and maintenance difficult. When using a large bag type back blowing dust collector for online ...
