Abstract

The invention discloses a synergistic sawdust biomass fuel utilizing tanning waste, comprising the following parts by weight: 58-64 parts of raw wood chips, 10-15 parts of chrome-containing leather chips, 12-16 parts of polyanionic cellulose, and 4-4 parts of attapulgite powder 8 parts, 3-5 parts of bastnaesite, 1-3 parts of oxygen enhancer, 0.2-0.5 parts of oxygen-enhancing synergist, 6-10 parts of bio-asphalt, 2-5 parts of cyanobacteria algae mud, 1-2 parts of ammonium sulfate Parts and 3~5 parts of substance A. The chromium-containing leather shavings of the present invention release a large amount of heat during the combustion process, and the wood chips and chromium-containing leather shavings are used to coordinate and match. With the combination of oxygen-increasing synergist and substance A, it releases a large amount of heat, and the hexavalent chromium Ions are not detected, and the purpose of waste utilization is achieved without secondary pollution.

Description

technical field [0001] The invention relates to the technical field of biomass fuels, in particular to synergistic sawdust biomass fuels using tanning waste and a preparation method thereof. Background technique [0002] Biomass fuel refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice bran, etc.), which is mainly different from fossil fuels. In the current national policy and environmental protection standards, direct combustion Biomass is a high-pollution fuel, which is only used in large stoves in rural areas and is not allowed to be used in cities. The application of biomass fuel is actually mainly biomass briquette fuel, which uses agricultural and forestry waste as raw materials and undergoes crushing, mixing, and extrusion , drying and other processes to make various shapes (such as block, granular, etc.), a new type of clean fuel that can be directly burned; with the rising interna...
