Multi-stage clean and efficient domestic waste pyrolysis gasification furnace and process

Abstract

The invention discloses a multi-segment clean and efficient household garbage pyrolysis and gasification furnace and process. The furnace comprises a furnace body. The two opposite sides of the upper end of the furnace body are each provided with a totally-closed bidirectional feeding pipe. An internal compaction air plate is mounted at the upper end in the furnace body in a suspended manner. An internal gas guide pipe is vertically mounted around the inner wall of the furnace body. The upper end of the internal gas guide pipe communicates with a gas outlet pipe. A through gas guide fire-leading pipe is further connected between the gas outlet pipe and an inner cavity of the furnace body and penetrates the internal compaction air plate to stretch into the lower portion of the inner cavity of the furnace body. The furnace body is further provided with a regenerated gas combustion-supporting system. According to the multi-segment clean and efficient household garbage pyrolysis and gasification furnace and process, upper-segment gas with many impurities returns to a fire inlet layer to be combusted through the regenerated gas combustion-supporting system, impurity pollutants are subjected to high-temperature treatment, and gas becomes cleaner; and the combustion-supporting system can increase the combustion speed and raise the combustion temperature, the garbage pyrolysis and gasification efficiency is higher, and efficient utilization of garbage heating and heat energy can be achieved.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a multi-stage clean and high-efficiency household garbage pyrolysis gasification furnace and a process. Background technique [0002] At present, waste landfill and waste incineration are mainly used for waste disposal. The waste landfill technology is backward, occupying land, and cannot completely dispose of waste. The effect is not good. Waste incineration pollutes the environment, is expensive and difficult to land. Contents of the invention [0003] The object of the present invention is to provide a new multi-stage clean and high-efficiency domestic waste pyrolysis gasifier and process for the problems of backward garbage treatment methods, poor treatment effects, and environmental pollution in the prior art. Uniform, very clean combustible gas, high efficiency of garbage pyrolysis and gasification, can realize scientific treatment of garbage and effici...
