Problems solved by technology

That is to say, in the prior art, it is impossible to smelt a single type of coal with a high degree of coalification into coke, especially anthracite
According to the existing technology, qualified coke products can only be produced by using caking coal such as fat coal or coking coal. If anthracite is used, it is difficult to be used as the main ingredient of coking coal blending because of its high degree of deterioration and colloids cannot be produced when heated.

Embodiment 1

[0043] An environment-friendly high-efficiency carbon is prepared from the following raw materials in parts by weight: 100 parts of single-species coal, 11 parts of asphalt, 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] Mix the raw materials according to the above proportions, and grind them; preheat to 130°C, add water, press into a block, and send it to a carbonization furnace for carbonization. The carbonization temperature is 900°C and the carbonization time is 4 hours. Atomize the water so that the smoke generated during the carbonization process is not yellow; out of the furnace, put it in water for rapid cooling.

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

Embodiment 2

[0048] An environment-friendly high-efficiency carbon is prepared from the following raw materials in parts by weight: 100 parts of single-species coal, 11 parts of asphalt, 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] Mix the raw materials according to the above proportions, and grind them; preheat to 130°C, add water, press into blocks, and send them to a carbonization furnace for carbonization. The carbonization temperature is 1100°C and the carbonization time is 8 hours. Atomize the water so that the smoke generated during the conversation is not yellow; take it out of the oven, put it in water for rapid cooling after it is out of the oven.

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

[0052] Compared with Example 1, using the same formula prolong...

Embodiment 3

[0054] An environment-friendly high-efficiency charcoal is prepared from the following raw materials in parts by weight: 100 parts of single-variety coal, 12 parts of asphalt, 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] Mix the raw materials according to the above proportions, and grind them; preheat to 130°C, add water, press into a block, and send it to a carbonization furnace for carbonization. The carbonization temperature is 900°C and the carbonization time is 4 hours. Atomize the water so that the smoke generated during the carbonization process is not yellow; out of the furnace, put it in water for rapid cooling.

[0057] Compared with Embodiment 1, the method of this embodiment is the same; the proportion of soda ash is larger, and the emission of sulfur dioxide and nitrogen oxides produced after combustion is less.

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...
