Embodiment 1

[0024] A method for preparing a laminated biomass briquette, comprising the steps of:

[0025] The first step, the preparation of the air-filled thin-layer substrate, crushes and pre-dries cellulose-based biomass debris such as rice husks, peanut shells, straw, bark, shavings, and wood chips, and adds an equivalent amount of biomass debris raw materials 3% quicklime and 4% kaolin by dry weight, inflated and mixed evenly, and extruded by a mold to obtain a rectangular inflated thin-layer substrate;

[0026] The second step is the surface treatment of the inflatable thin-layer substrate. The inflatable thin-layer substrate obtained in the first step is subjected to surface roughening treatment such as grinding and thermal etching, and then coated with an adhesive on the surface of the inflatable thin-layer substrate. The binder is a conventional fiber binder, such as waste paper pulp, hydrolyzed fiber, and what is used here is waste paper pulp;

[0027] The third step is lamina...

[0030] A method for preparing a laminated biomass briquette, comprising the steps of:

[0031] The first step, the preparation of the air-filled thin-layer substrate, crushes and pre-dries cellulose-based biomass debris such as rice husks, peanut shells, straw, bark, shavings, and wood chips, and adds an equivalent amount of biomass debris raw materials 8% quicklime and 3% kaolin by weight of the dry material, inflated and mixed evenly, and extruded with a triangular mold to obtain a triangular inflated thin-layer substrate;

[0032] The second step is the surface treatment of the inflatable thin-layer substrate. The surface of the inflatable thin-layer substrate obtained in the first step is subjected to surface roughening such as concave-convex texture treatment, and then the surface of the inflatable thin-layer substrate is coated with hydrolyzed fiber bonding agent;

[0033] The third step is lamination molding. Align the upper and lower surfaces of several inflatable thi...

Abstract

The invention relates to the technical field of biomass briquette fuel, and provides a method for preparing a laminated biomass briquette fuel, comprising the following steps: the first step, the preparation of an air-filled thin-layer substrate, and crushing cellulose-based biomass debris , pre-baking, adding quicklime equivalent to 3-8% of the weight of the dry material of the biomass debris raw material, 2-5% kaolin, inflating and mixing evenly, and extruding to obtain an inflated thin-layer substrate with a regular shape; the second step, inflating The surface treatment of the thin-layer substrate is to roughen the surface of the inflatable thin-layer substrate obtained in the first step, and then coat the surface of the inflatable thin-layer substrate with an adhesive; The upper and lower surfaces of several air-filled thin-layer substrates of the agent are aligned, and then the rollers are laminated by a roller press to obtain the final laminated biomass briquette. The invention has the characteristics of convenient processing, high compaction density, strong processability of forming thickness and convenient large-scale production.

Description

technical field [0001] The invention relates to the field of biomass briquettes, in particular to a method for preparing laminated biomass briquettes. Background technique [0002] with the development of economy. Energy and environmental issues have become the focus of global attention. The energy crisis caused by the depletion of traditional fossil energy sources such as coal, oil, and natural gas and the pollution caused by their combustion have become increasingly prominent. It is imminent to develop clean and renewable energy sources. Biomass is a diverse energy resource with a wide range of sources and simple application. It has a good application prospect as an effective alternative energy source. In recent years, the research and application of using forest processing waste and straw to make biomass pellet fuel has gradually increased. At present, biomass energy is mainly directly formed into strips, granules or blocks by direct extrusion. , The molding thickness a...
