Problems solved by technology

However, these existing technical solutions all have some defects: the single effect is better, the comprehensive effect is poor, and those that focus on improving combustion efficiency often have poor emission effects, and cannot simultaneously eliminate smoke, fix sulfur, and inhibit corrosion well, and focus on solving emission problems often cannot improve the combustion efficiency well at the same time

Embodiment 1

[0024] The components by weight of the coal additive are: 9 parts of tea meal or rapeseed residue, 27.5 parts of slag, 1 part of sodium percarbonate, 2.5 parts of potassium chlorate, 5 parts of potassium perchlorate, 6 parts of sodium chloride, and 7 parts of barium hydroxide , 3 parts of light magnesium oxide, 0.5 parts of manganese dioxide, 1.5 parts of nano-titanium dioxide, and 14 parts of humic acid.

[0025] The component raw materials are mixed according to the weight ratio, crushed to 40-60 mesh, and then put into a mixer and stirred for 5-10 minutes.

[0026] When in use, the above-mentioned coal additives are added to the coal at a weight ratio of 1:99 and mixed evenly. Applicable to all kinds of low-quality coal.

Embodiment 2

[0028] The components by weight of the coal additive are: 2 parts of tea meal or rapeseed residue, 5 parts of slag, 0.5 part of sodium percarbonate, 0.8 part of potassium chlorate, 1 part of potassium perchlorate, 2 parts of sodium chloride, and 4 parts of barium hydroxide , 1 part of light magnesium oxide, 0.1 part of manganese dioxide, 0.5 part of nano-titanium dioxide, and 3 parts of humic acid.

[0029] The preparation method is the same as above. When in use, the above-mentioned coal additives are added to coal with a sulfur content greater than 1.5% in a weight ratio of 1:99, and mixed evenly.

Embodiment 3

[0031] The components by weight of the coal additive are: 8 parts of tea meal or rapeseed residue, 17 parts of slag, 1.25 parts of sodium percarbonate, 2.4 parts of potassium chlorate, 4.5 parts of potassium perchlorate, 5 parts of sodium chloride, and 8 parts of barium hydroxide , 3 parts of light magnesium oxide, 0.9 parts of manganese dioxide, 1.5 parts of nano-titanium dioxide, and 12 parts of humic acid.

[0032] The preparation method is the same as above. When in use, the above-mentioned coal additives are added to coal with a sulfur content greater than 1.5% in a weight ratio of 1:99, and mixed evenly.

Abstract

The invention discloses an efficient and environment-friendly coal additive, comprising the following components in parts by weight: 2-15 parts of tea seed cake or rapeseed dregs, 5-33 parts of slag, 0.5-2 parts of sodium percarbonate, 0.8-4 parts of potassium chlorate, 1-8 parts of potassium perchlorate, 2-8 parts of sodium chloride, 4-12 parts of barium hydroxide, 1-5 parts of light magnesium oxide, 0.1-1.7 parts of manganese dioxide, 0.5-2.5 parts of nano-titania and 1-21 parts of humic acid. A preparation method comprises the following steps of: mixing the raw materials in weight ratio, crushing to 40-60 meshes, and placing into a stirrer to be stirred for 5-10 minutes. The coal additive provided by the invention is efficient and environment-friendly. The preparation method is simple and convenient and low in cost.

Description

technical field [0001] The invention relates to a high-efficiency and environment-friendly coal additive, and also relates to a preparation method of the coal additive. Background technique [0002] At present, coal is still an important energy source in my country, and it is also a one-time energy source. The reserves are constantly decreasing, and because of its combustion, it produces SO 2、 CO 2 And soot, etc. are also a kind of energy with serious combustion emission pollution. How to improve the combustion efficiency of coal and reduce pollution emissions is a technical problem that people are eager to solve. Now people are trying to use coal additives to improve coal combustion and emissions, and some technical solutions have also been proposed, such as the invention patent of coal additives with patent number 200610032354.X, the invention patent of coal energy-saving clean value-added agent with patent number 200910043153. However, these existing technical solution...
