Problems solved by technology

[0002] The existing treatment methods for municipal solid waste include incineration power generation, high-temperature composting, and sanitary landfill. The source of pollution only transfers and conceals the harmful points, and the economic benefits are relatively low
There is a kind of gasification method and garbage gasification furnace of a kind of similar municipal waste in the prior art, its patent number: 98111279. The port enters the furnace and reacts downward with the garbage-molded fuel. The process is simple, the operation is safe and hygienic, and there is no pollution. Because the garbage-molded fuel entering the furnace is oxidized at the upper part of the furnace first, high-temperature carbon dioxide is generated and then sucked. The lower reducing layer is reduced to combustible gases such as carbon monoxide, and at the same time, various harmful combustible components in the garbage briquette fuel can be oxidized at a high temperature in the furnace. When the fuel and the gasification agent (air) entering the furnace from the upper furnace mouth undergo high-temperature oxidation reaction in the upper part of the furnace, the fuel in the lower part of the high-temperature oxide layer in the furnace will form a reduction layer due to lack of oxygen, because the carbon in the fuel in the reduction layer cannot Fully oxidized, when the high-temperature carbon dioxide generated in the upper part is continuously pumped to the lower reducing layer, it is reduced to combustible gases such as carbon monoxide
Therefore, the carbon content in the ash in the lower part of the furnace is relatively high, resulting in a great loss of energy resources

Embodiment 1

[0011] The carbonization furnace that uses urban garbage and organic waste to produce activated carbon has an inner diameter of 2.4 meters and a height of 6.8 meters. The urban domestic garbage and organic waste are roughly broken and then screened to remove waste metals (copper, iron, etc.) and Inorganic substances such as waste glass, broken bricks, stones, etc., are then pulverized, dehydrated (dried), compressed into bulk raw materials by mechanical extrusion, put into the above-mentioned carbonization furnace, and oxidized in the upper part of the furnace at about 1200 ° C. The gasification reaction is first carried out at the high temperature of the layer, and the combustible gas such as carbon monoxide after the gasification reaction is continuously pumped into the semi-coke-shaped high-temperature carbonized layer at the lower part of the reduction layer and mixed with the water vapor in the water vapor coil installed on this layer Activate the carbon in the semi-coke (...

Embodiment 2

[0014] The carbonization furnace for producing activated carbon from municipal garbage and organic waste has an inner diameter of 1.8 meters and a height of 5.4 meters. The urban domestic garbage and organic waste are roughly broken and then screened to remove waste metals (copper, iron, etc.) and waste Inorganic substances such as glass, broken bricks, stones, etc., are then pulverized, dehydrated (dried) and compressed into massive raw materials by mechanical extrusion, and added to the above-mentioned carbonization furnace. Next, the gasification reaction is carried out first, and the combustible gas such as carbon monoxide after the gasification reaction is continuously sucked into the semi-coke-shaped high-temperature carbonized layer at the lower part of the reducing layer, and is mixed with the water vapor in the steam coil installed in this layer to activate the layer Activated carbon (crude product) is produced from the carbon in the semi-coke-like (900°C) high-tempera...

Embodiment 3

[0017] The carbonization furnace that uses urban garbage and organic waste to produce activated carbon has an inner diameter of 1.2 meters and a height of 4.6 meters. The urban domestic garbage and organic waste are roughly broken and then screened to remove waste metals (copper, iron, etc.) and waste. Inorganic substances such as glass, broken bricks, stones, etc., are then pulverized, dehydrated (dried) and compressed into massive raw materials by mechanical extrusion, and added to the above-mentioned carbonization furnace. Next, the gasification reaction is carried out first, and the combustible gas such as carbon monoxide after the gasification reaction is continuously sucked into the semi-coke-like high-temperature carbonized layer at the lower part of the reducing layer, and is mixed with the water vapor in the steam coil installed in this layer to activate the layer. The carbon in the semi-coke (900°C) high-temperature carbonization layer produces activated carbon (crude...

Abstract

The present invention is active carbon producing method with city garbage and carbonizing furnace. The production process includes: initial crushing, wind selection, sieving eliminating inorganic matter, crushing flammable organic matter, dewatering, mechanical extruding to produce block, dry distillation and oxidation in carbonizing furnace to produce high temperature CO2 while eliminating heavyhydrocarbon and harmful flammable matter, reduction to produce CO and other flammable gas, and producing active carbon by means of producing carbide layer, mixing with steam and activation while CO and other flammable gas being led out for use as fuel. The carbonizing furnace has simple and reasonable structure and is easy to manufacture and operate.

Description

technical field [0001] The present invention relates to an activated carbon and its carbonization furnace by using carbon-containing substances and organic wastes in municipal solid wastes with water vapor and combustible gas. agents and decolorizers. It belongs to the technical field of environmental protection. Background technique [0002] The existing treatment methods for municipal solid waste include incineration power generation, high-temperature composting, and sanitary landfill. The source of pollution only transfers and conceals the hazard points, and the economic benefits are relatively low. There is a kind of gasification method and garbage gasification furnace of a kind of similar municipal waste in the prior art, its patent number: 98111279. The port enters the furnace and reacts downward with the garbage-molded fuel. The process is simple, the operation is safe and hygienic, and there is no pollution. Because the garbage-molded fuel entering the furnace is ...
