The system comprises a garbage drying device, the garbage drying device is connected with a garbage pyrolysis gasification furnace and a heat conduction oil tank, and the garbage pyrolysis gasification furnace is connected with the heat conduction oil tank after passing through a secondary combustion chamber, a quench cooler and a white smoke elimination heat exchanger; the heat conduction oil tank is connected with the quench cooler and used for conducting heat exchange on medium-low-temperature heat conduction oil and then dividing the medium-low-temperature heat conduction oil into three paths, and one path is connected to the heat conduction oil tank through the air pre-heater and used for heating air entering the garbage pyrolysis gasification furnace. The second path is connected to the garbage drying equipment and is used for mixing and drying the garbage; and the third path is connected to the white smoke elimination heat exchanger and is used for heating the low-temperature smoke. According to the invention, reasonable distribution and use of energy are realized. And meanwhile, the working condition of furnace starting is optimized in the secondary furnace starting process, the problem of equipment damage caused by irregular operation of household garbage treatment equipment in villages and towns is solved, and reduction and harmless treatment of the household garbage in the villages and towns are truly achieved.
Description
technical field [0001] The invention belongs to the technical field of domestic garbage gasification and pyrolysis treatment, and in particular relates to a thermal storage quick-start type garbage pyrolysis gasification system and a method thereof. Background technique [0002] With the development of social economy, the output of domestic waste is increasing day by day, how to effectively deal with the domestic waste in villages and towns has become an urgent problem to be solved. Most domestic waste often contains a lot of water, and waste with a high water content will often damage the incineration environment during pyrolysis and incineration, resulting in flameout and difficulty in fully burning. The blockage of the flue, while the temperature of the chimney discharge is low, white smoke will appear. [0003] The domestic waste treatment in villages and towns is to burn the furnace during the day and close the furnace at night. When the furnace is started for the seco...
