Background
The biomass gas is prepared by using agricultural and forestry wastes (waste firewood, branches, shells, straws, rice hulls, bagasse, edible fungus residues, livestock and poultry manure and the like) biomass as a raw material, and performing a series of physical and chemical reactions such as drying, cracking, oxidation, reduction and the like under the condition of incomplete combustion to crack an organic hydrocarbon chain with higher molecular weight and convert the organic hydrocarbon chain into combustible gases such as carbon, hydrogen, carbon monoxide, methane, ethane, a small amount of low molecular weight carbon hydrogen and the like with lower molecular weight. Other components are nitrogen, carbon dioxide, water, tar, particulate matters and the like. The low-calorific-value combustible biomass gas generated by gasification is crude fuel gas, and the biomass gas which can be directly combusted and utilized can be obtained after filtration and purification.
The process flow for preparing the biomass gas by thermal cracking comprises the following steps: the biomass is used as raw material, air is used as gasifying agent (a proper amount of air is introduced into a gasification furnace), and after high-temperature reaction (generally 300-800 ℃), the organic matter volatile matter is decomposed into gas and solid carbon substance. Biomass pyrolysis is a process of producing gas under high temperature and anaerobic or anaerobic conditions, and can be referred to as gasification and pyrolysis. Under the action of heat, higher molecular weight organic hydrocarbons decompose to produce lower molecular weight gases such as nitrogen, methane, ethane, carbon dioxide, etc., and hydrogen and carbon monoxide are produced by the reduction of water vapor and carbon at high temperatures.
The biomass fuel gas generated by the thermal cracking of the biomass gasification furnace carries a large amount of ash impurities, the ash impurities are discharged along with the flowing of the biomass fuel gas, and the ash impurities are deposited in the transverse fuel gas pipeline, so that the pipeline is blocked easily and the use is influenced; if the mode of air blast positive pressure oxygen supply gasification is adopted, the high-temperature biomass gas and the air can explode or explode at a proper proportion, which is very dangerous, so that ash impurities in the crude gas are necessarily purified and then led out for utilization. The cyclone dust removal mode that current purification mode adds the cyclone in the gas pipeline, because the living beings gas contains tar molecule and ash content impurity, the gas can constantly reduce leaving behind the vaporizer temperature, living beings gas ash content impurity can be stained with and attach on the cyclone wall when the cyclone purifies, and long this past cyclone can take place to rotate not smooth even the jam (ash content impurity mixes has the tar molecule to have high viscosity after the temperature drop, and the clearance degree of difficulty is very big) and influence equipment continuous operation, causes the potential safety hazard.
