NOVELTY - Method of quick pyrolysis treatment and in situ conversion product utilization of sludge involves mechanically dewatering sludge, providing dried sludge to pyrolysis reactor, carrying out anaerobic heat treatment, then providing resultant product in volatile pyrolysis reactor, carrying out separation process, providing resultant product in fuel cogeneration unit and heat cogeneration unit, carrying out pyrolysis recycling and pyrolytic carbon activation process, providing the resultant product into activated carbon adsorption unit and purifying.    USE - Method of quick pyrolysis treatment and in situ conversion product utilization of sludge used in urban sewage treatment plant, papermaking industry, leather industry, and dyeing industry.    ADVANTAGE - The method enables economical and environmentally-friendly quick pyrolysis treatment and in situ conversion product utilization of sludge with high energy recovery rate, reduced secondary sludge and high harmless degree.    DETAILED DESCRIPTION - Method of quick pyrolysis treatment and in situ conversion product utilization of sludge involves mechanically dewatering sludge, removing 20-30% water, then providing resultant product in drying machine to obtain dry sludge having moisture content of 5-10%, providing dried sludge to pyrolysis reactor, heating at 500-600 degrees C, carrying out anaerobic heat treatment in which sludge feed rate and carrier gas flow rate are controlled, then providing resultant product in volatile pyrolysis reactor for 10-40 minutes, carrying out separation process in which treated output stream of heavy and light phase of thermosetting hot phase flow is separated on pipeline pyrocarbon active device, then collecting the resultant product, then providing the resultant product into cooling water circulating processor in which the phase flow of heat condensable gases are isolated which pyrolysis oil and non-condensable gases, separating resultant pyrolysis oil and mineral oil in the ratio of 1:1-3, providing the resultant product in fuel cogeneration unit and heat cogeneration unit, carrying out pyrolysis recycling and pyrolytic carbon activation process by providing the obtained heavy and light pyrolytic carbon in pyrolytic carbon activation device and activation device, introducing activated charcoal solution, discharging activated carbon, then purifying exhaust gas, providing the resultant product into activated carbon adsorption unit and purifying. The heavy solid-phase flow is heavy pyrolytic carbon. The heat output of the phase flow is passed through the primary cyclone, in which fine granular light-pyrolytic carbon is separated.
