Household garbage low-temperature pyrolysis treatment system

Abstract

A household garbage low-temperature pyrolysis treatment system comprises garbage specific gravity separation equipment, a pyrolysis furnace and an installation frame. The installation frame is provided with a first installation platform, a second installation platform and a third installation platform from top to bottom. The pyrolysis furnace penetrates through the second installation platform and is installed on the third installation platform. The furnace wall of the pyrolysis furnace is of a three-layer structure. An inner cavity of the pyrolysis furnace is divided into a heat preservation cavity, a heating cavity and a pyrolysis cavity from outside to inside through the furnace wall of the three-layer structure. The heat preservation cavity is filled with a heat preservation medium. In conclusion, the household garbage low-temperature pyrolysis treatment system conducts low-temperature pyrolysis on household garbage, energy sources in the garbage can be sufficiently recycled through the advanced biomass combustion and smoke waste heat utilization technologies, purposes of reduction, harmlessness and reclamation of garbage treatment are achieved, the requirement of urbanization in China for continuous development is met, and the urban household garbage low-temperature pyrolysis technology has broad market potential and the development space on the analysis of economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of domestic waste treatment, and in particular relates to a low-temperature pyrolysis treatment system for domestic waste. Background technique [0002] The existing goals of domestic waste treatment are: reduction, harmlessness, resource utilization, etc., among which reduction and harmlessness are the necessary goals for waste disposal. The currently commonly used domestic waste treatment methods include: pyrolysis, incineration, and safe landfill and composting technologies. Among them, the amount of flue gas generated by incineration is large, and the requirements for the supporting flue gas treatment system are complex, so the overall equipment cost is large and the technical requirements are high. High and difficult to operate, it is suitable for large-scale centralized treatment plants with a daily processing capacity of more than 100 tons in large cities; however, the disadvantages of safe landfill a...

Problems solved by technology

The currently commonly used domestic waste treatment methods include: pyrolysis, incineration, and safe landfill and composting technologies. Among them, the amount of flue gas generated by incineration is large, and the requirements for the supporting flue gas treatment system are complex, so the overall equipment cost is large and the technical requirements are high. High and difficult to operate, it is suitable for large-scale centralized treatment plants with a daily processing capacity of more than 100 tons in large cities; however, the disadvantages of safe landfill are obvious, it cannot achieve reduction, occupies a large area, and is prone to secondary pollution. A treatment method that is being minimized can only be used as an effective supplementary method in other waste treatment methods; while pyrolysis can effectively solve the problem of waste reduction and harmlessness, it has a simple structure and equipment The cost is low, and the operation is convenient. The more prominent point is that the low-temperature pyrolysis processes the organic matter in domestic waste, while the inorganic matter needs to be sorted out, such as bricks, glass bottles, etc.; but the existing pyrolysis treatment equipment is not tender. To meet the needs of the current market, the daily processing capacity is low, and no standardized application has been formed. Therefore, it is urgent to provide a low-temperature pyrolysis equipment to reduce, harmless and recycle the existing domestic waste.
