Embodiment 1

[0019] In the embodiment of the present invention, a coal-saving agent is composed of the following raw materials in parts by weight: 9 parts of potassium ferrate, 20 parts of polyaluminum iron silicate, 2 parts of potassium nitrate, 1 part of sodium acetate, and 10 parts of borax.

[0020] Mix and crush borax and polyaluminum silicate iron, pass through a 200-mesh sieve, then add triethanolamine twice the mass of the two, and stir at 50°C for 0.8h to obtain pretreated borax and polyaluminum silicate iron mixture. Mix potassium nitrate and sodium acetate and ball mill for 30 minutes, then add potassium ferrate to mix and ball mill for 30 minutes, then mix with the pretreated borax and polyaluminum iron silicate mixture, then stir at 58°C for 40 minutes, and then place in a UV lamp Irradiate for 50 minutes and cool down to room temperature.

Embodiment 2

[0022] In the embodiment of the present invention, a coal-saving agent is composed of the following raw materials in parts by weight: 18 parts of potassium ferrate, 30 parts of polyaluminum iron silicate, 8 parts of potassium nitrate, 5 parts of sodium acetate, and 18 parts of borax.

[0023] Mix and crush borax and polyaluminum iron silicate, pass through a 200-mesh sieve, add triethanolamine 5 times the mass of the two, and stir at 55°C for 1 hour to obtain pretreated borax and polyaluminum iron silicate mixture. Mix potassium nitrate and sodium acetate and ball mill for 40 minutes, then add potassium ferrate to mix and ball mill for 40 minutes, then mix with the pretreated borax and polyaluminum-iron silicate mixture, then stir at 62°C for 60 minutes, and then place in a UV lamp Irradiate for 70 minutes and cool down to room temperature.

Embodiment 3

[0025] In the embodiment of the present invention, a coal-saving agent is composed of the following raw materials in parts by weight: 12 parts of potassium ferrate, 22 parts of polyaluminum iron silicate, 4 parts of potassium nitrate, 2 parts of sodium acetate, and 12 parts of borax.

[0026] Mix and crush borax and polyaluminum iron silicate, pass through a 200-mesh sieve, add triethanolamine 4 times the mass of the two, and stir at 52°C for 1 hour to obtain pretreated borax and polyaluminum iron silicate mixture. Mix potassium nitrate and sodium acetate and ball mill for 35 minutes, then add potassium ferrate to mix and ball mill for 35 minutes, then mix with the pretreated borax and polyaluminum-iron silicate mixture, then stir at 60°C for 50 minutes, and then place in a UV lamp Irradiate for 60 minutes and cool down to room temperature.

Abstract

The invention discloses a coal saver as well as a preparation method and application thereof. The coal saver consists of the following raw materials in parts by weight: 9-18 parts of potassium ferrate, 20-30 parts of poly-aluminum ferric silicate, 2-8 parts of potassium nitrate, 1-5 parts of sodium acetate and 10-18 parts of borax. The preparation method for the coal saver comprises the following steps: mixing and crushing the borax and poly-aluminum ferric silicate, enabling the mixed and crushed borax and poly-aluminum ferric silicate to pass through a 200-mesh sieve, and adding triethanolamine to carry out stirring treatment, thereby obtaining a pre-treated mixture of the borax and poly-aluminum ferric silicate; and mixing and ball-milling potassium nitrate and sodium acetate, adding potassium ferrate to mix and ball-mill, stirring and mixing with the pre-treated mixture of the borax and poly-aluminum ferric silicate, irradiating the pre-treated mixture by use of an ultraviolet lamp, and cooling to the room temperature. The coal saver is non-toxic, is free from pungent smell, and is free of corrosivity and pollution; raw materials are cheap and easily available, the production cost is low, and the adding amount is less; and the coal saver has remarkable coal-saving, combustion-supporting and desulfuration effects, can remarkably reduce the carbon content of ash, can reduce emission of harmful gas, and can improve the thermal efficiency of coal.

Description

technical field [0001] The invention relates to the technical field of coal additives, in particular to a coal-saving agent and its preparation method and application. Background technique [0002] Coal is one of the main energy and chemical raw materials in our country, especially as an energy source, it is the most widely used energy raw material in modern industry. my country is quite rich in coal resources, and the proven reserves rank among the top in the world, but they will be gradually depleted in 100 years. However, as the reserves of coal resources on the earth become less and less, the price of coal is getting higher and higher. As far as the quality of coal is concerned, the quality of coal in our country is uneven. Medium and high sulfur coal with a sulfur content of more than 2% in coal And high-sulfur coal accounts for about 1 / 3 of the total reserves. During the combustion process of coal, due to its poor quality, the combustion is not sufficient, resulting ...
