Example Embodiment

[0016] Example 1

[0017] Embodiment 1 is a preferred embodiment of the present invention, as attached figure 1 Shown: a segmented pressurized organic waste gasification furnace, including an upper furnace body 1, a lower furnace body 1, an ignition zone 3, an air supply zone 4, and an ash outlet 5, which are sequentially combined and connected. A concentric cylinder. The total height of the furnace body is 4000 mm, the height of the lower furnace body 2 is 2000 mm, and the diameter is 1500 mm. The height of the upper furnace body 1 is also 2000 mm, and the diameter is reduced to 80% of the diameter of the lower furnace body 2, that is, the upper furnace body 1 The diameter is 1200 mm. The bottom end of the upper furnace body 1 slightly extends into the top of the lower furnace body 2 and is about 20 cm deep. The upper and lower furnace bodies are welded together with a steel plate made of the same material as the furnace body at a certain slope. The diameter difference betwee...

Example Embodiment

[0023] Example 2

[0024] Embodiment 2 is another preferred embodiment of the present invention. In embodiment 2, the diameter of the lower furnace body 2 is 2000 mm, the diameter of the upper furnace body 1 is 1500 mm, and the bottom end of the upper furnace body 1 slightly extends into the top of the lower furnace body 2 , About 10 cm deep, which is the same as in Example 1.

[0025] The working principle of the present invention is: in the process of gasification of organic waste, because the upper furnace body 1 is narrowed, the gas in the furnace moves from bottom to top, the gas density in the upper furnace body 1 increases, and the gas in the upper furnace body 1 rises to After the top, the rising gas returns quickly under the action of greater pressure. Therefore, the density of the middle pyrolysis zone 11 will also increase correspondingly, and the pyrolysis speed will increase accordingly. The lower reduction zone 12 and oxidation zone 13 The speed will increase accordi...

Abstract

The invention discloses a segmental supercharged organic garbage gasifier. The gasfier comprises an upper gasifier body, a lower gasifier body, a seed region, a blow-in region and a soot door which are sequentially combined and connected, and is characterized in that the upper and lower gasifier bodies are formed by two concentric cylinders, the height of the lower gasifier body is the same as that of the upper gasifier body, and the diameter of the upper gasifier body is 80 to 85 percent of that of the lower gasifier body; the bottom end of the upper gasifier body extends into the top end of the lower gasifier body by 10 to 20cm in depth, the diameter differential place where the upper gasifier body is connected with the lower gasifier body is sealed by welding a steel plate to be used as an air getting tank, and one end of the air getting tank is connected with an air getting pipe through an opening; an air distribution plate is arranged between the seed region and the blow-in region; the top of the upper gasifier body is an opening for feeding garbage, and a top cover is arranged at the upper part of the opening. According to the gasifier provided by the invention, through diminishing the upper gasifier body and supercharging and increasing speed skillfully, the gasification effect and the quality of producing gas are improved.

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...
