This invention provides a high-calorific-value biomass fuel made from agricultural waste and its preparation method, belonging to the field of biomass energy utilization technology. The biomass fuel comprises agricultural waste and cellulase or lignin; the amount of cellulase or lignin added is 0.5%-1.0% of the agricultural waste. The preparation method is as follows: the agricultural waste is dried and coarsely crushed, then sieved, magnetically separated, and air-separated before fine crushing to obtain powdered raw material; cellulase or lignin is added to the powdered raw material, mixed evenly, and then extruded to obtain the high-calorific-value biomass fuel. The preparation method of this invention employs a combination of two-stage crushing, multi-stage sieving, intelligent magnetic separation, and air separation, as well as multi-stage drying, intelligent moisture control, and dry-wet material ratio. The prepared biomass fuel has a stable calorific value and high energy density, significantly reduced pollutant emissions, strong agricultural waste digestibility, low raw material cost, and stable supply, thus promoting energy structure transformation.

This invention belongs to the field of waste gas treatment technology, specifically disclosing a flare gas incineration treatment system for EVA production. The system includes a daily gas buffer tank and an emergency gas buffer tank, each connected in series with a liquid separator, a water seal tank, and a cooler. The gas outlets of the two coolers are connected to an incinerator, and the flue gas outlet of the incinerator is connected in series with an induced draft fan and a chimney. Addressing the safety risks, such as explosions, posed by direct combustion of flare gas generated during EVA production, this invention achieves safe, efficient, and compliant emissions of flare gas by classifying and collecting the flare gas, separating it into liquids, applying a water seal, pre-treating it with cooling, and precisely monitoring key parameters, combined with efficient incineration in an incinerator. This solves the problem that direct combustion of flare gas containing hydrocarbons such as ethylene, vinyl acetate, and organic solvents generated during EVA production can easily lead to explosions or flameout accidents due to gas composition imbalance.
