preparation example Construction

[0028] The preparation method of the above-mentioned baked coal comprises the following steps:

[0029] Step S110, pulverize white coal and binder, take 80-95 parts by weight of white coal of 50-70 mesh, 3-6 parts by weight of binder, stir evenly, add 2-8 parts by weight of desulfurizer and 4- 6 parts of plant fibers were marinated for 15-24 hours, stirred again, and extruded to obtain coal sticks.

[0030] Among them, in the process of pulverizing the white coal and the binder, if the pulverized particles are too large, the bonding strength of the roasted coal will be affected; Difficult to shape, affecting the strength of the coal fired. Therefore, the mesh number of the control particles is 50-70 mesh.

[0031] The purpose of pickling the white coal, binder and desulfurizer is to allow the white coal to fully absorb the binder and desulfurizer. In this embodiment, the above components are stirred and then piled up for pickling.

[0032] After the white coal, binder, des...

Embodiment 1

[0036] Pulverize white coal and binder, get 80 kilograms of 50-70 mesh white coal, 3 kilograms of binder, 2 kilograms of desulfurizer, 4 kilograms of plant fiber;

[0037] Wherein, in the binder, by weight, there are 280 parts of kaolin, 85 parts of humic acid, 295 parts of bentonite, and 80 parts of cornstarch;

[0038] In the desulfurizer, by weight, 20 parts of hexamethylenetetramine, 45 parts of sodium nitrate, 45 parts of potassium nitrate, 20 parts of potassium permanganate, 20 parts of industrial salt, 45 parts of industrial essence, 8 parts of quicklime, hydrogen Sodium oxide 8 parts;

[0039] marinating the above components for 15-24 hours, stirring again, and extruding to obtain coal sticks;

[0040] The coal sticks are baked at 400-500° C. for 24 hours to obtain baked coal.

Embodiment 2

[0042] Pulverize white coal and binder, get 95 kilograms of 50-70 mesh white coal, 6 kilograms of binder, 8 kilograms of desulfurizer, 6 kilograms of plant fiber;

[0043] Wherein, in the binder, by weight, there are 320 parts of kaolin, 105 parts of humic acid, 310 parts of bentonite, and 100 parts of cornstarch;

[0044] In the desulfurizer, by weight, 30 parts of hexamethylenetetramine, 55 parts of sodium nitrate, 55 parts of potassium nitrate, 30 parts of potassium permanganate, 30 parts of industrial salt, 55 parts of industrial essence, 12 parts of quicklime, hydrogen 12 parts of sodium oxide;

[0045] marinating the above components for 15-24 hours, stirring again, and extruding to obtain coal sticks;

[0046] The coal sticks are baked at 400-500° C. for 24 hours to obtain baked coal.

Abstract

The invention discloses roasted coal. The roasted coal is prepared from the following raw materials in parts by weight: 80-95 parts of white coal, 3-5 parts of a binder, 2-8 parts of a desulfurizer and 4-6 parts of plant fibers, wherein the binder comprises 280-320 parts of kaolin, 85-105 parts of humic acid, 295-310 parts of bentonite, 80-100 parts of corn starch; the desulfurizer comprises 20-30 parts of hexamethylene tetramine, 45-55 parts of sodium nitrate, 45-55 parts of potassium nitrate, 20-30 parts of potassium permanganate, 20-30 parts of industrial salts, 45-55 parts of industrial essence, 8-12 parts of quick lime and 8-12 parts of sodium hydroxide. The roasted coal adopts the desulfurizer with different components and proportions, and the desulfurizer is combined with the white coal by virtue of the binder to prepare the roasted coal. The sulfur content of the obtained roasted coal is 0.5, which is about 2 / 5 that of the white coal, so that when the roasted coal is combusted, the exhausted sulfur dioxide is greatly lowered to meet the environment-friendly idea. The invention further discloses a preparation method of the roasted coal.

Description

technical field [0001] The invention relates to the field of energy, in particular to environment-friendly roasted coal and a preparation method thereof. Background technique [0002] As people pay more and more attention to the environment, baking coal is also developing in the direction of environmental protection. Generally, the roasted coal is carbonized coal or carbonized rods. The sulfur content in such carbonized coal or carbonized rods is too high, and a large amount of sulfur dioxide gas will be produced during combustion, which is not in line with the concept of environmental protection. Contents of the invention [0003] Based on this, it is necessary to provide an environmentally friendly roasted coal with low sulfur content and a preparation method thereof. [0004] A kind of baked coal, by weight, is prepared from the following raw materials: [0005] 80-95 parts of white coal, 3-6 parts of binder, 2-8 parts of desulfurizer, 4-6 parts of plant fiber; [00...
