Embodiment 1

[0023] A kind of briquette binding agent, it is made up of guar gum, sucrose, magnesia, wherein sucrose needs through pulverizing, crosses 60 mesh sieves, guar gum, sucrose, magnesia mass ratio is 1:1:1, three Mixed evenly can be used as a binder. When using, take 1kg of coal powder with a particle size of less than 3mm, add 50g of binder, stir and mix evenly, add 200g of water, stir evenly, put it in the mold, add 30MPa pressure for 10-20s, and dry the pressed coal naturally. be usable.

Embodiment 2

[0025] A briquette binder, which consists of fenugreek gum, sucrose, and magnesium oxide, wherein the sucrose needs to be pulverized and passed through a 60-mesh sieve, and the mass ratio of guar gum, sucrose, and magnesium oxide is 2:1:1, and three Those mixed evenly can be used as a binder. When using, take 1kg of coal powder with a particle size of less than 3mm, add 40g of binder, stir and mix evenly, add 200g of water, stir evenly, put it in the mold, add 30MPa pressure for 10-20s, and dry the compressed coal naturally. be usable. When the briquette of this embodiment is burned, it can produce a faint medicinal fragrance.

Embodiment 3

[0027] A briquette binder, which consists of xanthan gum, sucrose, and magnesium oxide, wherein the sucrose needs to be pulverized and passed through a 60-mesh sieve, and the mass ratio of guar gum, sucrose, and magnesium oxide is 2:1:1, and the three Mixed evenly can be used as a binder.

Abstract

The present invention relates to a briquette binder and a use method thereof. The briquette binder comprises a soluble polysaccharide complex and a metal oxide according to a mass ratio of 2:1-3:1. The use method comprises: selecting coal powder with a particle size of less than 3 mm as a bonding object, and uniformly mixing a briquette binder and the coal powder, wherein the mass of the briquette binder is 3-5% of the mass of the coal powder; adding water to the briquette binder and coal powder mixture, and stirring, wherein the mass of the added water is 15-20% of the mass of the coal powder; and applying 20-30 MPa pressure with equipment, molding, and naturally drying so as to complete the briquette production. According to the present invention, the briquette binder production raw materials are easy to obtain, and the production cost is low; the briquette binder does not contain strong alkali or harmful substances, such that the injury on worker body can be avoided during the briquette production; the inorganic component content is low, such that the influence on the heat generation of the briquette is low; and the briquette binder can absorb a lot of sulfur dioxide produced during coal combustion so as to reduce combustion pollution.

Description

technical field [0001] The invention belongs to the field of fuel binders, in particular to a briquette binder and a using method thereof. Background technique [0002] Coal is the most abundant energy resource in my country. It is cheap, easy to obtain and widely used. With the improvement of my country's environmental protection requirements in recent years, especially higher requirements are put forward for the amount of dust and sulfur-containing compounds produced by coal combustion. In large coal-consuming enterprises such as thermal power plants, the emission of dust and sulfur compounds can usually be reduced through a dedicated dust removal and purification system. These measures are difficult to implement in small-scale coal use sites such as barbecue coal. Therefore, the coal fuel itself needs to be treated. Among them, the pulverized coal can be processed through bonding and molding, which can effectively reduce the escape of dust and improve the utilization r...
