Molded coal auxiliary agent compound

Abstract

The invention discloses a molded coal auxiliary agent compound comprising the following raw material components by mass: 10-15 parts of sodium carboxymethyl cellulose, 5-8 parts of polyving akohol, 3-5 parts of sodium tripolyphosphate, 5-10 parts of sodium dihydrogen phosphate dihydrate, 1-3 parts of calcium hydroxide, 2-4 parts of nano calcium carbonate, 3-6 parts of ferric chloride, 3-8 parts of copper chloride, 2-5 parts of ammonium hydrogen carbonate, 10-15 parts of limestone, 3-5 parts of potassium chlorate, 2-5 parts of potassium sulfate, 1-3 parts of sodium permanganate, 2-3 parts of ammonium nitrate, 4-6 parts of sodium chlorite, 5-8 parts of ammonium chloride, 20-30 parts of mullite powder, 20-25 parts of titanium dioxide, 30-40 parts of sunflower oil residue, 1-5 parts of polyvinyl butyral resin, 3-8 parts of polyvinyl alcohol fiber, 3-5 parts of polyvinylpyrrolidone and 10-20 parts of water. The molded coal auxiliary agent compound has the advantages of low cost, and molded coal prepared by mixing wash coal mud and wash middling coal needs no drying.

Description

technical field [0001] The invention relates to the technical field of an additive compound, in particular to an additive compound for briquette. Background technique [0002] The production of existing briquettes mostly adopts the mixed molding of organic liquid binder and pulverized coal. After forming, it is dried by special drying equipment to make briquettes. However, the briquettes produced by the existing drying process require equipment investment Large, a considerable amount of fuel coal is used in drying, and the self-pollution is serious, the strength of the finished product is low, and the cost of the binder used in the molded coal is high. During the combustion process, due to the collapse of the molded coal, the dust in the flue gas is large. It does not meet environmental protection standards when burned. The shortcomings of the above briquettes are mainly caused by the added compound additives, which seriously restrict the development of shaped coals. Theref...

[0002] The production of existing briquettes mostly adopts the mixed molding of organic liquid binder and pulverized coal. After forming, it is dried by special drying equipment to make briquettes. However, the briquettes produced by the existing drying process require equipment investment Large, a considerable amount of fuel coal is used in drying, and the self-pollution is serious, the strength of the finished product is low, and the cost of the binder used in the molded coal is high. During the combustion process, due to the collapse of the molded coal, the dust in the flue gas is large. Does not meet environmental protection standards when burned

The shortcomings of the above briquettes are mainly caused by the added compound additives, which seriously restrict the development of shaped coal. Therefore, it is imperative to improve and increase the added compound additives.
