Abstract

The invention discloses a solid waste and hazardous waste gasification melting furnace with central gas collection, and relates to the field of solid waste treatment melting furnaces. The solid wasteand hazardous waste gasification melting furnace comprises a furnace top charging system, a furnace throat central gas collecting device and a furnace body gasifying and melting part, wherein the furnace top charging system is used for feeding materials into the furnace, and comprises a material receiving hopper, a sealing valve and a sealing material barrel, and a nitrogen filling pipe and a material level meter are arranged in the sealing valve; the furnace throat central gas collecting device is used for central gas collection, collecting the furnace gas in the furnace from the middle of the furnace and discharging the gas, and comprises a gas guiding beam, a gas collecting bell and a throat shell body, and the gas collecting bell is fixed to the center of the throat shell body throughthe gas guiding beam; and the furnace body gasifying and melting part comprises a furnace shell, a refractory lining, a furnace hearth and a furnace cylinder, and a tuyere device and a liquid discharging port are arranged on the furnace cylinder. According to the solid waste and hazardous waste gasification melting furnace with central gas collection, a furnace top sealing valve and a nitrogen filling facility are arranged, the charging sealing form is improved, the furnace throat central gas collecting device is arranged, the furnace gas guiding mode is changed, the problems of feeding sealing, furnace air flow and the like are solved, meanwhile the structure is simple, the manufacturing cost is low, and the application range is wide.

Description

technical field [0001] The invention relates to the field of melting furnaces for solid waste treatment, in particular to a solid waste and hazardous waste gasification melting furnace with central gas collection. Background technique [0002] In the production and life of modern society, a large amount of solid waste and hazardous waste generated need to be treated innocuously. The shaft type melting furnace that uses fuel combustion to provide heat source can crack and gasify the organic matter in hazardous waste and solid waste, and generate fuel for utilization. , The melting of inorganic substances into glass can stably solidify harmful heavy metals and make them reused as resources. Compared with other treatment methods such as electric melting, it has the characteristics of less equipment investment and lower operating costs. [0003] The existing furnace gas outlet is under the feeding port and has a sealing material cylinder. The ring chamber is connected to the fu...
