Abstract

The invention discloses a preparation method and device for biomass fast-burning bricks. The preparation method is to add sodium bicarbonate, potassium permanganate, zeolite powder, sodium silicate and fatty alcohol polyoxygen after drying the biomass to remove impurities. Sodium vinyl ether sulphate, mixed evenly, the intermediate product is obtained through two heating reactions, then add water, zinc nitrate, calcium oxide, bentonite, epoxy resin, gum arabic and xanthan gum, mix evenly, heat up and extrude , to obtain biomass fast-burning bricks. The device provided by the invention comprises a drying unit, a mixing unit, a reaction unit, a pulverizing unit and an extruding unit connected in sequence, and the connection between the units is through a conveyor belt. The biomass quick-combustible brick obtained by the preparation method provided by the invention is easy to ignite when used, has a fast burning speed and is fully burned, and does not emit dust and other pollutants to the surroundings. The preparation process of the device provided by the invention can be fully automated and controlled, and the preparation efficiency is high.

Description

technical field [0001] The invention belongs to the field of biomass recovery and utilization, and in particular relates to a preparation method and device of biomass fast-burning bricks. Background technique [0002] Biomass refers to various organisms produced through photosynthesis using the atmosphere, water, land, etc., that is, all living organic substances that can grow are collectively referred to as biomass. It includes plants, animals and microorganisms. Broad concept: Biomass includes all plants, microorganisms, animals that feed on plants and microorganisms, and their wastes. Representative biomass is crops, crop waste, wood, wood waste and animal manure. Narrow concept: Biomass mainly refers to lignocellulose such as straw and trees other than grain and fruit in the process of agricultural and forestry production, leftovers of agricultural product processing industry, agricultural and forestry waste, and poultry manure and waste in the process of animal husban...
