Waterproof type biomass briquette and preparation method thereof
2014
The invention relates to the technical field of biomass briquettes, and provides a waterproof type biomass briquette and a preparation method thereof. The biomass briquette has a layered edge-sealing structure and comprises a basic fuel layer and a waterproof fuel layer; the basic fuel layer is a cuboid block, the upper and lower surfaces and the periphery of the basic fuel layer are provided with the waterproof fuel layer through pressing, and the waterproof fuel layer pressed on the periphery of the basic fuel layer is in V-shaped; and the biomass of the basic fuel layer is agricultural wastes, and the biomass of the waterproof fuel layer is lignin and/or oil crop wastes. The concrete steps for preparing the waterproof biomass briquette material comprise: preparing the basic fuel layer, preparing the waterproof fuel layer, performing primary pressing forming, performing edge sealing and secondary pressing forming, and the like. The product is convenient for processing and excellent in waterproof performance, and has the characteristics that the formed thickness is strong in processability and large-scale production is convenient.
