Abstract
The utility model discloses a biomass gas steel rolling system, belonging to the technical field of comprehensive utilization of biomass. The system mainly comprises a fluidized-bed gasification furnace, a fuel gas purifying unit and a steel rolling furnace, wherein the fluidized-bed gasification furnace is connected with the steel rolling furnace through the fuel gas purifying unit. According to the system disclosed by the utility model, after being added into the fluidized-bed gasification furnace, the biomass raw material is carried by the bed material in the furnace to realize fluidization, and the fuel gas is generated through quick pyrolysis and gasification reactions; the air for gasification is added from the bottom of the fluidized-bed gasification furnace by an air blower through an equal-pressure chamber; and after being dedusted, the biomass gas is directly fed into the steel rolling furnace and is burnt with wind through a fuel gas nozzle. The system disclosed by the utility model can convert biomass into clean fuel gas which is efficiently burnt in the steel rolling furnace to release heat, thereby remarkably reducing the emission of sulphur dioxide and nitrogen oxide. The solid emission generated by gasification is plant ash; and the whole system realizes tar-free and sewage-free emission in the production process.
Description
Technical field
A kind of biological fuel gas rolling system of the utility model, belong to biomass comprehensive and utilize field.
Technical background
Cut-off to 2009 end of the year, the total amount of the steel rolling furnace of China has surpassed 310,000, steel rolling furnace year 400000000 tons, consumption coal, annually to airborne release, surpass 6,000,000 tons of SO
2, 8,000,000 tons of flue dust, 1.64 hundred million tons of CO
2, produce simultaneously the lime-ash of 8,700 ten thousand tons.Steel rolling furnace energy consumption and disposal of pollutants all occupy national industrial trade the second, are only second to the power station steel rolling furnace, and the pollution that the steel rolling furnace discharging of national key cities causes has even surpassed the power station steel rolling furnace.The energy-saving and emission-reduction of steel rolling furnace industry have become urgent problem, the pendulum the society and government in face of.
The recovery energy of China's biomass resource, particularly agricultural, production of forestry changing rejected material to useful resource, recovery energy field, industrialization level is very low, a large amount of agriculturals, production of forestry waste are not utilized effectively, be not only huge waste, but also become the important sources of environmental pollution.Although and current small-sized fixed bed gasification mode has been carried out extensive popularization, because equipment is difficult for maximizing, operation difficulty continuously, be difficult to realize the application of industrialization, mass-producing.
Therefore, by utilizing biomass fluid bed pyrolytic gasification technology etc. to realize biomass efficient, clean utilization, make biological flue gas carry out commercial application in the replacement of fuel field of steel rolling furnace, realize agriculture production changing rejected material to useful resource, recovery energy, substitute fossil energy, can realize " three win " of economic benefit, environmental benefit and social benefit.
