Biomass briquette taking sand plants as base material and production method thereof

Abstract

The invention relates to a biomass briquette taking sand plants as a base material and a production method thereof. The production method comprises the following steps of: taking sand plants as a main raw material, adding coal to improve and supplement heat, mechanically crushing, grinding and forming; and the production method is characterized by adding secondary calcium-based mineral slag for sulfur fixation, adding a mineral adhesive for controlling the forming, press forming after stirring evenly, or granulating, screening, and air drying to obtain the briquette product. The scheme effectively solves the key problem of high input and low output in the sand control process, organically combines the sand plants and the secondary calcium-based mineral slag by using the flammability of the sand plants and the desulfurization and adhesion properties of the secondary calcium-based mineral slag, solves the problems of poor economic benefit and serious environment pollution caused by simple utilization of the conventional sand plants, solves the problem of reutilization of a large quantity of calcium carbide waste slag and magnesium smelting slag discharged annually by high energy-bearing industries, solves the problems of environmental disruption and high energy consumption caused by using quicklime as a sulfur fixation agent currently, and solves the problem of energy shortage currently.

Description

technical field

[0001] The invention relates to a fuel briquette and a production method thereof, in particular to a biomass briquette using psammophytes as a base material and a production method thereof. Background technique

[0002] The existing routes of using biomass to produce energy include: first, using plant fruits or juices to produce biodiesel or fuel ethanol; second, using plant branches, straw and garbage to produce gas or directly burning power; third, configuring biomass briquettes , Instead of traditional coal and other fuels, this technology is mostly based on coal, compounded with plant straw. All biomass is a specific type; the world's biomass resources are very rich, due to the different types, in fact, it is necessary to develop technologies and products tailored to local conditions in order to produce good economic and social benefits.

[0003] In the current production of biomass briquette or plant briquette, it is necessary to add quicklime as a sulf...
