Problems solved by technology

It can be divided into two types: inorganic binder and organic binder. The briquettes produced with inorganic binders have high thermal stability, but have a lot of ash, and the fixed carbon content of briquettes has a large decrease in combustion efficiency. Low, such as briquettes produced by using lime as a binder, not only has a lot of ash, but also has a fixed carbon reduction of more than 18%; briquettes produced by using organic binders have high cold strength, but high volatile content and poor thermal stability , there are many combustion products, and the process is relatively complicated. For example, the production of briquettes using asphalt requires dry distillation at 500-550°C, and the high volatile content causes secondary pollution to the environment.
Using the above-mentioned existing binders to make briquettes, the pelleting rate is not very high, only 60-80%, and the production cycle is long

Abstract

The invention discloses an environment-friendly industrial briquette composite binder and a preparation method thereof. Humic acid, alumina, common seepweed herb seed cake meal, water and the like are used as raw materials; the preparation process is simple and convenient; the briquette prepared by the method has the advantages of little drop of the solid carbon content, good binding property, high pelletizing rate, high cold/hot strength, good thermal stability, low cost, short production cycle and the like.

Description

technical field [0001] The invention relates to an industrial briquette binder and a preparation method thereof, in particular to an environment-friendly industrial briquette composite binder and a preparation method thereof. Background technique [0002] The existing binders for producing industrial briquettes mainly take white mud, lime, clay, coal tar, asphalt, cement, starch, etc. as raw materials. It can be divided into two types: inorganic binder and organic binder. The briquettes produced with inorganic binders have high thermal stability, but have a lot of ash, and the fixed carbon content of briquettes has a large decrease in combustion efficiency. Low, for example, briquettes produced by using lime as a binder not only have a lot of ash, but also have a fixed carbon reduction of more than 18%; briquettes produced by using organic binders have high cold strength, but high volatile content and poor thermal stability , There are many combustion products, and the ...
