Embodiment 1

[0016] This patent mainly provides a formula for making briquettes by using high-volume tar slag and coke powder, which can not only efficiently use the waste tar slag in the coking plant to make briquette coke, but also comprehensively utilize the coke powder in the coking plant, saving Coal resources, in line with circular economy.

[0017] The technical solution is: a formula for producing briquette, the weight ratio of the main components of the formula is:

[0018] 15% of tar residue, 3% of coke powder, 1% of quicklime powder, 1% of gelatinized starch, 0.1% of polyurethane, and 79.9% of coking coal.

[0019] Moisture / %

[0020] The main technical indicators of coke end:

[0021] project

[0022] CaO+MgO content

[0023] project

[0024] project

[0025] Using this formula to make briquette adopts the above materials, and it can be produced by using common equipment in briquette factories. The technical point is that th...

Embodiment 2

[0026] Example 2 is basically the same as Example 1, but the formula ratio is as follows: 18% of tar residue, 5% of coke powder, 0.8% of quicklime powder, 2% of gelatinized starch, 0.2% of polyurethane, and 74% of coking coal.

Embodiment 3

[0027] Example 3 is basically the same as Example 1, but the formula ratio is as follows: 20% of tar residue, 3% of coke powder, 1.5% of quicklime powder, 3% of gelatinized starch, 0.05% of polyurethane, and 72.45% of coking coal.

Abstract

The invention relates the molded coal made with tar oil slag and breeze, comprising 15-20wt% tar oil slag, 2-6wt% breeze, 0.1-1.5wt% calcium oxide powder, 0.5-3wt% gelatinized starch, 0.05-0.3wt% polyurethane, and 70-80wt% close burning coal. The molded coal has good modeling and demoulding property, the compression strength is 150 N / ball, drop strength is 99%, and the water resistance is good. The tar oil slag is the main waste in coking workplace, and the breeze is not fully utilized. The invention has the advantages of reducing environmental pollution, saving treatment expenses, good economic benefit and environmental benefit.

Description

technical field [0001] The invention belongs to waste resource recycling technology, and relates to a coking briquette produced by using tar residue and coke powder in a coking plant. Background technique [0002] At present, in the production of coking plants, the main polluting waste is tar residue, which contains various toxic and carcinogenic substances such as benzene, phenol, and naphthalene, and is very harmful. If it is directly discharged or stacked, it will not only directly affect the quality of the air environment in the area, but also penetrate into the ground through the surface, pollute the groundwater source, and endanger people's physical and mental health. Therefore, tar residue is a hazardous waste, and enterprises are not allowed to process and discharge it privately. At present, there are two commonly used treatment methods. One is directly mixed with coking coal and smelted back, but there are problems such as adhesion to the casing, wear and corrosion...
