Embodiment 1

[0080] A flash multi-chamber gasifier, such as figure 1 , 2 As shown in and 5, the structure is as follows:

[0081] The gasification furnace is sequentially divided into a carbonization zone 1, an oxidation zone 2 and a reduction zone 3 along its length; the carbonization zone 1 and the oxidation zone 2 are separated by a first wall 7; the interior of the carbonization zone 1 A first annular air box 6 is provided on one side close to the first wall 7; a plurality of material guide holes through which gasification products can pass are provided on the first wall 7.

[0082] The gasification furnace is surrounded by an annular sealing cover 5, and a sealed cavity 4 is formed between the sealing cover 5 and the gasification furnace; the sealing cover 5 is provided with an oxygen inlet 20, and the oxygen inlet 20 is connected to There is an oxygen delivery device.

[0083] The first annular wind box 6 communicates with the sealed cavity 4 , and the air duct of the first annula...

Embodiment 2

[0085] A flash multi-chamber gasifier, such as Figure 3-5 As shown, the structure is as follows:

[0086] The gasification furnace includes a fire grate, and the fire grate is composed of a plurality of T-shaped fire grate stems 18; the bent end of the fire grate stem 18 extends toward the axis of the gasifier, and the other end is connected to the gasifier. The inner wall of the gasification furnace is connected.

[0087] The gasification furnace is sequentially divided into a dry distillation zone 1, an open flame chamber 201, a high temperature chamber 203, a secondary high temperature chamber 301, a heating chamber 303, and a constant temperature chamber 305 along its length. A wall 7 separates, the open flame chamber 201 and the high temperature chamber 203 are separated by the second wall 202, the high temperature chamber 203 and the second high temperature chamber 301 are separated by the third wall 204, the second high temperature chamber 301 and the heating chamber ...

Abstract

The invention provides a flash multi-chamber gasification furnace. The gasifier is sequentially divided into a retort zone, an oxidation zone and a reduction zone along its length; the retort zone and the oxidation zone are separated by a first wall; the retort zone is provided with a first annular wind box on the side close to the first wall; The first wall is provided with a plurality of guide holes that can pass through the dry distillation product; the gasifier is surrounded by a ring-shaped sealing cover, and a sealed cavity is formed between the sealing cover and the gasifier; the sealing cover is provided with an oxygen inlet, and the oxygen inlet An oxygen delivery device is connected; the first annular air box communicates with the sealed cavity, and the air delivery pipe of the first annular air box extends into the inside of the oxidation zone. The invention can realize deflagration effect, and make the time for garbage incineration rising from 400 DEG C to 700 DEG C less than 0.2 seconds, so that the garbage incineration will not produce dioxin, and has the advantage of being green and environment-friendly.

Description

technical field [0001] The invention relates to the field of domestic waste treatment equipment, in particular to a flash multi-chamber gasifier. Background technique [0002] In order to remove the chimney when incinerating domestic waste, the prior art crushes and dries the waste and sends it into a rotary kiln gasifier to convert it into gas. The gas is methanated after being discharged from the gasifier, and the calorific value can be increased to meet the national natural gas standard. This process of converting domestic waste into natural gas has no chimney, that is, de-chimneyization, and is easily accepted. [0003] Patent No. ZL 201420594937.1 discloses a horizontal rotary gasifier with wheel grate, which has two notable features: [0004] One is that the wheel grate is L-shaped, with a 90° bend. It forms a "pocket" with the circular arc of the rotary kiln shell, and is as long as the rotary kiln shell. It is fixed on the inner wall of the rotary kiln, and the Th...
