PROCEDURE FOR REFRIGERATING AND PURIFYING A GAS CONTAINING ULTRA-FINE PARTICLES, ESPECIALLY, HIGH FURNACE GAS OR GENERATOR GAS, AND DEVICE FOR ITS REALIZATION.

摘要

IN A PROCESS FOR THE COOLING AND DEPURATION OF HOT GAS CONTAINING ULTRA-FINE PARTICLES, SUCH AS THAT OF A COAL GASIFICATION FACILITY, THAT OF GENERATOR GAS PRODUCED IN A FUSION GASIFIER OR THAT OF HIGH FURNACE GAS FACILITY FROM A REDUCING FACILITY BY MELTING, IN A PRE-WASHER BY PACKAGING AND FOLLOWING IN AN ANNULAR NOZZLE WASHER, AT A STAGE OF WASHING BY SATURATION PRIOR TO THE PRE-WASHER BY PACKAGING, THE HOT GAS WITH WATER VAPOR IS ENRICHED WITH WIDE USE OF HIGH-USE WATER VAPOR. OF HOT WATER SUPPLIED, AT LEAST APPROXIMATELY UP TO ITS SATURATION LIMIT AND THEREFORE COOLES AND THE DUST PARTICLES ARE WET. IN THE FOLLOWING STAGES OF COOLING AND WASHING, THE PRECIPITATION OF THE DUST IS SUPPORTED BY A QUICK CONDENSATION OF THE WATER VAPOR.
