Coal pyrolysis flue gas control treatment equipment continuous operation period prolonging method and coal pyrolysis flue gas control treatment equipment continuous operation period prolonging apparatus

Abstract

The present invention relates to a coal pyrolysis flue gas control treatment equipment continuous operation period prolonging method and a coal pyrolysis flue gas control treatment equipment continuous operation period prolonging apparatus, and provides a coal pyrolysis flue gas control treatment equipment continuous operation period prolonging method, which comprises: (i) carrying out pre-separation treatment on raw material flue gas in a coal pyrolysis process through micro-swirling flow separation to remove large-particle-size catalyst particles from the flue gas; (ii) carrying out gas flowbalancing on the obtained flue gas, and feeding into the particle bed of a boiling bed separator to filter out fine particles entrained in the flue gas; and (iii) discharging the clean flue gas obtained through the two filtrations so as to be processed and utilized. The invention further provides a coal pyrolysis flue gas control treatment equipment continuous operation period prolonging apparatus.

Description

technical field [0001] The disclosure belongs to the field of environmental protection of coal chemical industry, especially relates to the technical field of continuous operation of dust-containing oil-gas separation equipment in coal chemical industry, including the method improvement of dust separation and recovery in coal pyrolysis process, and is suitable for improving the efficiency of processing and separating particulate matter in coal pyrolysis flue gas and equipment operating cycle. Specifically, the present disclosure provides a method and a device for extending the continuous operation period of coal pyrolysis flue gas control and treatment equipment. Background technique [0002] Coal is one of the important energy resources with abundant reserves in my country, and its reserves account for 60% to 70% of the total energy consumption in my country. Its development and utilization have been widely concerned. In recent years, the problem of resource waste and envi...
