Description
Technical Field
The invention relates to the technical field of renewable energy sources, in particular to a biomass cold-hot electric carbon-gas fertilizer multi-product intelligent output system.
Background
Biomass energy is considered to be a potentially effective alternative to fossil energy. Firstly, biomass is a clean energy source, although being used as fuel to release carbon dioxide when burning, the biomass absorbs carbon dioxide in the environment in the growing process, forms a carbon circulation system taking green plants as ligaments, maintains carbon balance in the earth ecology, theoretically realizes zero emission of carbon dioxide, and can fundamentally relieve greenhouse gas emission (mainly CO)2) The biomass has low sulfur and nitrogen content compared with coal, and can effectively reduce SO generated by the combustion of fossil fuel as energy2、NxOyAnd (nitrogen oxide) and the like. Secondly, biomass as a carbon source can be used to directly refine liquid fuels or be converted into energy and chemicals by other techniques (physical, biological, or chemical, etc.). Thirdly, the biomass resource reserves are abundant, the distribution is wide, and the species isThe classes and morphologies are diverse and reproducible.
Biomass gasification is a process in which biomass is converted into a gas fuel by pyrolysis, oxidation, reduction, and other reactions with a gasifying agent (air, oxygen-rich gas, and the like) at a high temperature. The biomass gasification has high energy conversion rate, easy pipeline transportation after conversion and high combustion efficiency.
Meanwhile, the improvement of the life quality of people puts higher requirements on energy supply forms, and the residents not only need gas and electric energy, but also need heating and cooling in life, can generate biomass charcoal and pyroligneous liquor with high added values, and can also bring raw materials for industrial and agricultural production.
At present, the energy poly-generation system has few product forms. In the prior art, a biomass poly-generation system relates to two to three energy product forms, and has the advantages of less products, low additional value and no contribution to the popularization and application of the technology. The output of the energy form is poor in controllable selectivity. In the prior art, the selectivity of energy output is poor, even the selective output of output products is not available, and only two or three energy products can be output and fixed after the system is shaped. The energy utilization rate is low. In the prior art, because the energy product is single, a plurality of byproducts are discarded as wastes, thus not only causing the waste of energy utilization, but also causing the environmental pollution. The systematicness is poor, the prior art mostly focuses on a certain single device or a single link, and the study energy of the system is less than the study energy of the system and the intelligent output of products is more than the study energy. The environmental pollution is high, and the existing poly-generation technology still has the problems of standard exceeding of smoke emission, environmental pollution and the like.
Chinese patent application No.: CN201410573068.9 discloses biomass poly-generation equipment and a method of integral pyrolysis-flue gas combined cycle, which mainly comprise a pretreatment system, a drying system, a temperature regulating system, an integral pyrolysis furnace, a comprehensive combustion furnace, a fuel gas purification system, a carbon forming system, a gas storage cabinet and a solar heat collector. The method is characterized in that: pretreatment systems connects drying system, and whole pyrolysis oven and gas clean system are connected to drying system, and gas clean system, charcoal forming system and comprehensive combustion furnace are connected to whole pyrolysis oven, and gas clean system connects gas holder and comprehensive combustion furnace, and gas holder connects comprehensive combustion furnace and user's pipe network, and comprehensive combustion furnace connects whole pyrolysis oven. The method has the characteristics of three-in-one functions of pyrolysis, pyrolysis gas pyrolysis and solid carbon decoking, is integrated, has a controllable reaction process, and can continuously and efficiently produce high-calorific-value gas and products such as high-temperature carbon, wood tar, pyroligneous liquor and the like. The purposes of fully cracking biomass and effectively controlling the product quality are achieved. However, the technology still has few products, and cannot meet various energy requirements of users, particularly the requirements of the users on electricity, heat and cold.
In addition, chinese patent application No.: CN201110345197.9 discloses a biomass distributed cooling, heating and power poly-generation energy system: the technical scheme includes that the device comprises a substance combustor, a Stirling engine, a heat exchanger, a generator and an absorption refrigerator, smoke generated by the biomass combustor is purified and then enters the Stirling engine, generated power supplies power to the generator through an output shaft to generate electric energy, generated waste heat gas enters the absorption refrigerator through a hot waste gas pipe to be refrigerated and heated, and cooling water preheats air and supplies hot water through the heat exchanger to realize poly-generation of cold, heat and electricity. The scheme explains a device which utilizes biomass synthesis gas to perform combustion power generation and a waste heat boiler to perform waste heat recovery heat supply and an absorption type refrigerating device to perform cold supply, but the technology and the scheme improve the energy utilization rate, but the overall cost is very high, and the economy is not high for further large-scale popularization. Meanwhile, the invention only provides three energy product forms of cold, heat and electricity, the energy forms are few, and biomass byproducts are not treated in time, so that pollution and instability of equipment operation are brought.
In conclusion, the technology always has the defects that the cost is too high, various requirements of user energy cannot be met simultaneously, or optimal operation adjustment cannot be made according to specific practical conditions, and intelligent control cannot be realized.
