Briquette coal binder, biomass briquette and preparation method thereof

Abstract

The invention relates to the technical field of briquettes, and relates to a briquette binder, preparation method of a briquette binder, a biomass briquette and a preparation method of the biomass briquette, the briquette binder is prepared by the following steps: crushing biomass raw materials, and treating the biomass raw material i by adopting a hot-dissolving extraction method to obtain the briquette coal binder. The method disclosed by the invention mainly uses agricultural and forestry wastes such as wheat straws, pine wood chips, cotton straws, corn straws, rice straws and the like as the biomass raw materials, and prepares the biomass briquette by virtue of a hot press molding process; the biomass briquette prepared by the method disclosed by the invention is high in forming rate,the heat stability is good, the drop strength index is excellent, the ignition point is low, compressive strength is high, heat value is high, the production process is simple in operation and high infeasibility, the raw materials are wide in source and low in price, the biomass resources such as agriculture and forestry wastes can be effectively utilized, contribution is made to environmental protection, and resource utilization and energy utilization of biomass such as the agriculture and forestry wastes are realized, so that low-rank coal can be cleaned and efficiently utilized.

Description

technical field

[0001] The invention relates to the technical field of molded coal, and relates to a molded coal binder, a preparation method of the molded coal binder, a biomass molded coal and a preparation method of the biomass molded coal. Background technique

[0002] China's energy structure determines that coal will be used as the main energy consumption for a long period of time in the future, but coal combustion will produce a large amount of dust, NO 2 , CO 2 and SO 2 Pollutants such as coal and other pollutants cause serious environmental pollution problems, so the development of clean coal technology is an inevitable trend of my country's energy development. With the continuous improvement of coal mining mechanization, the proportion of pulverized coal in raw coal is also increasing. The increase in the proportion of pulverized coal not only reduces the combustion efficiency of loose coal, but also seriously pollutes the environment. The development of brique...
