Oxygen-free sticky garbage pyrolyzing method and system

Abstract

The invention discloses an oxygen-free sticky garbage pyrolyzing method and an oxygen-free sticky garbage pyrolyzing system. The oxygen-free sticky garbage pyrolyzing method comprises the following steps: performing garbage pretreatment: softening outwardly transported garbage by afterheat, adding a recycling liquid with an additive to increase the fluidity of a material, and sending the materialto a cracking furnace through specific hydraulic conveying equipment; performing garbage cracking decomposition: distilling, carbonizing and decomposing solid waste in the cracking furnace through multi-stage temperature control under an anaerobic condition, and according to the technological temperature and the heating rate, under the action of a catalyst, decomposing organic matters of the solidwaste into combustible gas, carbon and liquid compounds; reprocessing a cracking decomposition product: separating, purifying and synthesizing inorganic matters, the combustible gas, the carbon and the liquid compounds into building materials, fuel gas, regenerated finished products and solvents / oils. Under medium-temperature and low-temperature, catalytic and completely oxygen-free conditions, complex mixed garbage can be treated, the material is continuously fed, high-efficiency pyrolysis is achieved, and the fuel gas, the carbon and other regenerated products are produced.

Description

technical field [0001] The invention relates to a process for treating industrial viscous wastes, in particular to a treatment method and system for anaerobic thermal cracking of industrial viscous wastes such as waste oil sludge, paint and ink residues to achieve resource utilization and harmless discharge. Background technique [0002] Human activities will inevitably produce all kinds of waste, including domestic waste, industrial waste, agricultural and forestry waste, electronic waste, medical waste and so on. The vast majority of garbage exists in the form of mixtures, among which the organic substances that have a greater impact on human health and the environment are of a wide variety. It mainly includes synthetic polymer materials that are difficult to degrade in nature, such as plastics, adhesives, fibers, paints, etc.; it also includes naturally degradable biomass, such as food, straw, paper products, wood products, etc.; the third part It is industrial waste con...
