Abstract
The utility model discloses a biomass gas calcining magnesium oxide system and belongs to the technical field of biomass gasification heat utilization. The biomass gas calcining magnesium oxide system is characterized in that a charging port is formed in the lateral wall of a gasifier. A cyclone dust collector is communicated with a burner through a gas pipe. An air pipe is communicated with a rotary kiln through an air nozzle. A natural gas pipe is installed in the burner and communicated with the rotary kiln. The gas pipe is communicated with the rotary kiln through a gas nozzle. The calcining magnesium oxide system has the advantages of being high in efficiency, stable in operation, pollution-free and the like. The biomass gas calcining magnesium oxide system solves the technical problem that an existing biomass heat utilization technology is difficult to apply in the calcining magnesium oxide system.
Description
Technical field
The utility model relates to gasifying biomass heat utilization technology field, particularly a kind of biological fuel gas magnesia calcined system.
Background technology
China's biomass fuel aboundresources, Devoting Major Efforts To Developing biomass fuel resource helps to improve China take fossil oil as main energy structure, can reduce the discharging of sulfide and oxynitride, can alleviate Greenhouse effect again.Biomass gasification technology has realized that low-grade Wood Adhesives from Biomass is high-quality gas, can be in fossil energies such as a lot of fields petroleum replacing, Sweet natural gases.
Magnesium hydroxide is calcined in the high temperature of 1900 ℃ can be obtained high-quality magnesium oxide, the biological fuel gas calorific value is low, its theoretical combustion temperature is 1500 ℃ of left and right only, directly add the rotary kiln burning with biological fuel gas, be difficult to satisfy the demand of magnesia calcined high temperature, existing magnesia calcined technology greatly mainly with coal, oil, Sweet natural gas or electric energy as thermal source, China's fossil energy store content is limited, and can produce larger pollution to atmosphere in combustion processes, the domestic biological fuel gas that there is no is applied to the magnesia calcined technical field at present.
Be applied to magnesia calcined with the alternative coal of biological fuel gas, oil, Sweet natural gas, electric energy, when saving the high-quality energy, protection of the environment, improved the market competitiveness of enterprise.
