Example Embodiment

[0042] Example one

[0043] An environmentally friendly high-efficiency carbon prepared from the following raw materials by weight: 100 parts of a single variety of coal, 11 parts of pitch, 9 parts of solid binder, 15 parts of soda ash, 13 parts of gypsum and 10 parts of sodium humate.

[0044] The specific preparation method is as follows:

[0045] Prepare and mix the raw materials according to the above ratio, and grind them; preheat to 130°C, add water, press into a block, send to the carbonization furnace for carbonization, carbonization temperature 900°C, carbonization time 4h, and spray during the carbonization process Atomized water makes the flue gas produced in the carbonization process not yellow; after being discharged from the furnace, it is put into water for rapid cooling.

[0046] The charcoal produced by the above treatment removes most of the harmful substances and reduces the sulfur dioxide produced after combustion.

Example Embodiment

[0047] Example two

[0048] An environmentally friendly high-efficiency carbon prepared from the following raw materials by weight: 100 parts of a single variety of coal, 11 parts of pitch, 9 parts of solid binder, 15 parts of soda ash, 13 parts of gypsum and 10 parts of sodium humate.

[0049] The specific preparation method is as follows:

[0050] Prepare and mix the raw materials according to the above proportions, and grind them; preheat to 130℃, add water, press into a block, send it to the carbonization furnace for carbonization, carbonization temperature 1100℃, carbonization time 8h, and spray during the carbonization process Atomized water makes the flue gas produced during the conversation not yellow; after being discharged from the furnace, put it into the water to cool rapidly.

[0051] The charcoal produced by the above treatment removes most of the harmful substances and reduces the sulfur dioxide produced after combustion.

[0052] Compared with the first embodiment, the ...

Example Embodiment

[0053] Example three

[0054] An environmentally friendly high-efficiency carbon prepared from the following raw materials by weight: 100 parts of a single variety of coal, 12 parts of pitch, 8 parts of solid binder, 21 parts of soda ash, 10 parts of gypsum and 10 parts of sodium humate.

[0055] The specific preparation method is as follows:

[0056] Prepare and mix the raw materials according to the above ratio, and grind them; preheat to 130°C, add water, press into a block, send to the carbonization furnace for carbonization, carbonization temperature 900°C, carbonization time 4h, and spray during the carbonization process Atomized water makes the flue gas produced in the carbonization process not yellow; after being discharged from the furnace, it is put into water for rapid cooling.

[0057] Compared with the first embodiment, the method of this embodiment is the same; the specific gravity of soda ash is larger, and the emission of sulfur dioxide and nitrogen oxides produced aft...

Abstract

The invention relates to a coal carbonization technology, in particular to a preparation method of efficient and environment-friendly coal and a product of the efficient and environment-friendly carbon, and belongs to the field of coal improvement. The efficient and environment-friendly coal is prepared through the steps that raw materials are subjected to grinding and compression moulding, and then high-temperature carbonization is carried out. The raw materials comprise, by mass, 100 parts of single-variety coal, 1-30 parts of asphalt, 1-30 parts of adhesive and 1-30 parts of carbonate or bicarbonate. By means of carbonization treatment, sulfur-containing matter and other matter capable of generating polluting gas after being combusted in the coal are basically removed, therefore, the coal has the advantage of being environmentally friendly as fuel and further has the advantage of being efficient, and fire coal can be saved by about 30%.

Description

technical field [0001] The invention relates to a coal carbonization technology, in particular to a high-efficiency and environment-friendly carbon production method and its products, which belong to the field of coal improvement. Background technique [0002] With the increasingly stringent requirements of environmental protection standards for environmental protection, many enterprises that use coal as fuel now release carbon dioxide, sulfur dioxide, nitrogen oxides, smoke and other pollutants that exceed the current national environmental protection standards, and are subject to environmental protection departments. Request rectification or stop production. Therefore, some powerful enterprises have to use natural gas or electricity as the heating source, and some weak enterprises may go bankrupt directly. Finding a highly efficient, environmentally friendly, and low-cost fuel has become the fuel demand direction of enterprises, and it is also the research and development...
