Rural-garbage pyrolyzing furnace

Abstract

The invention discloses a rural-garbage pyrolyzing furnace. The rural-garbage pyrolyzing furnace comprises a furnace body, wherein a furnace chamber is arranged in the furnace body, the position, close to the bottom of the furnace chamber, of the furnace body is fixedly connected with one side of a stop block, an ash falling opening is formed in the right side, close to the stop block, of the furnace body, an ash removing opening is formed in the left side, close to the stop block, of the furnace body, a feeding opening is formed in the inner wall of one side, close to the top, of the furnacebody, the top of the furnace body is fixedly connected with a water-vapor separation chamber, and a flue gas purification chamber (using quicklime and activated carbon to purify flue gas) is connectedabove the water-vapor separation chamber. According to the rural-garbage pyrolyzing furnace, through the arranged furnace chamber, mainly for treating combustible organic matter such as remote ruralgarbage and straw, a raw garbage layer, a garbage drying layer, a garbage pyrolyzing layer and an oxygen-poor combustion layer of the furnace body achieve drying, sufficient gasification and carbonization of organic matter in garbage, and under the oxygen-free or oxygen-poor condition, when the temperature is controlled to be 850 DEG C-950 DEG C, decomposable substances in the garbage are decomposed into combustible gas, toxic and harmful substances are completely decomposed, and harmlessness is achieved.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a rural garbage pyrolysis furnace. Background technique [0002] Waste treatment refers to the process of transforming waste into suitable for transportation, utilization, storage and final disposal. The purpose of harmlessness, reduction and resource utilization can be achieved through treatment. At present, the more commonly used waste treatment methods at home and abroad can be roughly divided into two categories: centralized and decentralized. Among them, the centralized treatment mainly includes sanitary landfill, waste incineration and power generation, etc., and the decentralized treatment mainly includes composting. Incinerator method and pyrolysis equipment method. [0003] The sanitary landfill method is a method of burying waste according to the sanitary landfill engineering standards by using engineering means, using mountain streams, valleys, and depressi...

AI Technical Summary

Problems solved by technology

[0004] Sanitary landfill, composting and incineration are used in the existing garbage process. During the use, the following methods occupy a large area, have strict requirements on natural conditions, complex operation and management, and high equipment costs. Garbage Fertilizer costs are high, operation and management costs are high, and there are strict requirements on waste components and management levels; in addition, if the supporting measures for incineration are not properly controlled, a large amount of acid gas and highly toxic carcinogenic organic components ( Such as dioxin, etc.) to form secondary pollution, and other shortcomings, so it is not suitable for rural garbage treatment, and rural garbage treatment is suitable for pyrolysis, so it is urgent to invent a pyrolysis type rural garbage pyrolysis furnace
