Problems solved by technology

[0002] In the process of coal mining, the amount of coal dust accounts for about 30% of the total coal. The application of coal dust is mostly processed into shaped coal, which is suitable for civil and industrial production. The simplest method of processing shaped coal is Mix with yellow mud to form, use yellow mud as binder, usually 40-60 catties of yellow mud is mixed with every 100 kg of coal dust, which greatly reduces the content of fixed carbon, reduces the fuel value of coal, and increases the ash content. Moreover, the briquette is fragile, not strong, and not suitable for industrial production. Some artificial binders are used to increase the strength of the briquette and reduce the amount of binder. It is better than using yellow mud alone as a binder, and is suitable for industrial briquettes. Production, such as Chinese invention patent 00134771.3 "Industrial Briquette Composite Adhesive", the briquette produced by this binder is suitable for industrial production, but not completely suitable for civilian use. Although the solid briquette has a high combustion value, it is not easy to catch fire

Embodiment 1

[0045] Embodiment 1, the production of industrial briquette: at first select high-quality anthracite by the technical index of production briquette, then prepare water-soluble briquette binder, the water-soluble briquette binder compounding method is to add organic Add 10 kg of adhesive, add 15 kg of water, heat and stir until completely dissolved, add 50 kg of saturated lime aqueous solution, then add 20 kg of water glass with 45-56 degrees Baume, then add 1 kg of potassium nitrate, and then add sodium fluorosilicate 0.3 kg, add water to 100 kg, stir while adding, until all raw materials are completely dissolved.

[0046] Then follow the process steps

[0047] A. Raw material crushing: the raw material is anthracite and red mud, the crushing particle size is ≤2.5mm; the sieve residue is 10-20%

[0048] B. Quantitative feeding: the weight ratio of coal to red mud is 100:2;

[0049] C. Mixing: Add 11 kg of water-soluble briquette binder to the mixed powder of 100 kg of coal a...

Embodiment 2

[0056] Embodiment 2, the production of civil briquette

[0057] The production conditions of civil briquettes are not as strict as those of industrial briquettes, and high-quality anthracite is not necessarily selected for raw coal. The preparation of water-soluble binders in the production of civil briquettes: add organic binders to the reaction kettle Add 5 kg of glue, add 20 kg of water, heat and stir until completely dissolved, add 50 kg of saturated lime water, then add 10 kg of water glass with 45-56 degrees Baume, 3 kg of water-soluble combustion aid ammonium nitrate, preservative sodium fluorosilicate 0.2 kg, add water to 100 kg, stir while adding until all raw materials are completely dissolved, then process according to the process steps of Example 1, wherein the difference in step B is that the weight ratio of coal to red mud is 100:8, step C mixing is different in that 10 kg of water-soluble briquette binder is added to 100 kg of mixed powder of coal and red mud fo...

Abstract

The invention discloses a water-soluble briquette adhesive and a process applied to briquette production thereof and relates to an adhesive for briquette for production industry and civilian use and application thereof. The water-soluble briquette adhesive is combined by organic water-soluble adhesive, inorganic water-soluble adhesive, water-soluble preservative, water-soluble combustion improverand water-soluble sulfur and fluorine removal agent, and the process flow for producing the briquette by utilizing the adhesive is as follows: A. raw material crushing; B. quantitative feeding; C. mixing and stirring; D. pinching and stirring; E. homogenizing; F. molding; and G. drying. The adhesive has little use amount in the briquette production, high adhesive strength, high content of fixed carbon and high fuel value, fire-leading is easy, the firepower is large, and soot smell is difficult to smell.

Description

technical field [0001] The invention relates to an adhesive for producing industrial and civil coal briquettes and its application, in particular to a water-soluble adhesive for briquette coal and its application to the production of briquette coal. Background technique [0002] In the process of coal mining, the amount of coal dust accounts for about 30% of the total coal. The application of coal dust is mostly processed into shaped coal, which is suitable for civil and industrial production. The simplest method of processing shaped coal is Mix with yellow mud to form, use yellow mud as binder, usually 40-60 catties of yellow mud is mixed with every 100 kg of coal dust, which greatly reduces the content of fixed carbon, reduces the fuel value of coal, and increases the ash content. Moreover, the briquette is fragile, not strong, and not suitable for industrial production. Some artificial binders are used to increase the strength of the briquette and reduce the amount of binde...
