Sectional pressurized organic waste gasifier

Abstract

The invention discloses a segmented pressurized organic waste gasification furnace, which comprises an upper furnace body, a lower furnace body, an ignition area, an air supply area and an ash outlet which are sequentially combined and connected, and is characterized in that: the upper and lower furnace bodies are Two concentric cylinders, the height of the upper and lower furnace bodies is equal, the diameter of the upper furnace body is 80-85% of the diameter of the lower furnace body; the bottom of the upper furnace body extends into the top of the lower furnace body 10-20 cm deep, and the upper The difference in diameter between the furnace body and the lower furnace body is sealed and welded with a steel plate, which is used as an air intake tank, and one end of the air intake tank is connected to the air intake pipe through an opening; there is an air distribution plate between the ignition area and the air supply area; the upper furnace The top of the body is an opening for putting in garbage, and a top cover is provided on the upper part of the opening. In the present invention, by reducing the size of the upper furnace body, the pressure is increased ingeniously and the speed is increased, thereby improving the gasification effect and the quality of gas production.

Description

technical field [0001] The invention relates to an organic waste gasification furnace, in particular to a segmented pressurized organic waste gasification furnace. Background technique [0002] At present, the more common waste gasifiers are mainly divided into three types: up-suction type, down-suction type and medium-conduction type. The principle is to feed the gasifier from the top of the gasifier, and add a small amount of wood chips and other biomass raw materials to support combustion in the bottom layer of the furnace body. , open the bottom outside the furnace body for ignition, oxygen supply, air supply and ash removal. Combustible gas is generated through four thermochemical reaction processes of oxidation, reduction, pyrolysis and drying, and is discharged through the external pipe of the exhaust port. The difference between the three methods is that the gas inlets are different. The up-suction type takes gas from the upper part of the furnace body, the down-suct...
