As the international community pays more and more attention to issues such as ensuring energy security, protecting the ecological environment, and responding to climate change, accelerating the development and utilization of renewable energy sources such as biomass has become a universal consensus in all countries in the world. Major strategic initiatives. Biomass energy is an important renewable energy source, which comes directly or indirectly from the photosynthesis of plants. It is generally obtained from agricultural and forestry waste, domestic waste and livestock and poultry manure. Combustion, gasification, liquefaction), biological conversion (such as fermentation to methane) and other forms into solid, liquid and gaseous fuels. Biomass energy is the fourth largest energy source in the world, after coal, oil and natural gas. Biomass energy, as clean and renewable energy, is the only carbon resource that can replace fossil energy into gaseous, liquid and solid fuels and other chemical raw materials or products.
Classification Of Bio-Energy
According to different sources, biomass suitable for energy use can be divided into five categories: forestry resources, agricultural resources, domestic sewage, and industrial organic wastewater, municipal solid waste and livestock and poultry manure.
Forestry biomass resources refer to the biomass energy provided by forest growth and forestry production processes, including fuelwood forests, loose wood in the forest tending and thinning operations, residual branches, leaves, and wood chips, etc .; Branches, sawdust, sawdust, tips, slabs, and truncated heads; wastes from forestry by-products, such as shells and kernels.
Agricultural biomass energy resources refer to agricultural crops (including energy crops); wastes from agricultural production processes, such as crop stalks (corn stalks, sorghum stalks, wheat stalks, straw, bean stalks, and cotton stalks) that remain in the farmland during harvest Etc.); waste from the agricultural processing industry, such as rice husks left over from agricultural production.
Domestic sewage is mainly composed of various drainages from urban residents' living, business and service industries, such as cooling water, bath drainage, toilet drainage, laundry drainage, kitchen drainage, and fecal sewage.
Industrial Organic Wastewater
Industrial organic wastewater is mainly wastewater discharged during the production process of alcohol, brewing, sugar making, food, pharmaceutical, papermaking and slaughtering industries, etc., which are rich in organic matter.
Municipal Solid Waste
Municipal solid waste is mainly composed of solid waste from urban residents, commercial and service waste, and a small amount of construction waste. Its composition is relatively complicated and is affected by factors such as the average living standard of local residents, the structure of energy consumption, urban construction, natural conditions, traditional habits, and seasonal changes.
Advantages Of Biomass Energy
Bioenergy is an energy source that can replace petroleum
With the rising trend of oil prices and limited oil resources, it is urgent to find a new energy source that can replace petroleum energy. Bioenergy is a non-polluting energy source that can replace petroleum energy, while water, wind, solar, nuclear and other new energy sources are only suitable for power generation and heating.
Diversity Advantages Of Bioenergy Products
Bioenergy products include liquid bioethanol and diesel, solid prototypes and molded fuels, and gaseous biogas. Bioenergy can replace oil, coal and natural gas, as well as heat and power generation.
"Recyclability" and "environmental protection" of bioenergy
Bioenergy is a product produced during the detoxification and recycling of the organic waste in agriculture, forestry, and urban and rural areas. All living materials of biofuels can enter the biological cycle of the earth. Even the released carbon dioxide will be absorbed again by plants And participate in the cycle of the earth to achieve pollution-free and zero emissions. Material environmental protection, sustainability, and resource recyclability are urgently needed in the development of modern new energy, and the production model of bioenergy is also extremely modern.
Bioenergy helps create jobs
Bioenergy creates more job opportunities. The "Green Jobs" report issued by the United Nations Environment Programme states that "by 2030, the renewable energy industry will create 20.4 million jobs, of which biofuels will contribute 12 million."
Biomass energy utilization technology
Biomass energy technologies mainly include biomass power generation, bio-liquid fuels, biogas, solid formed fuels, bio-based materials, and chemicals. Among them, biogas is commonly known as biogas, which is a product of microbial groups that synergistically ferment degradable organic waste under anaerobic conditions. The shrinking of traditional energy supply and the need to increase the share of renewable energy in energy consumption make biogas increasingly important. Biogas technology has matured and achieved industrialization. Europe is the region with the most mature biogas technology, and biogas engineering equipment in developed countries such as Germany, Sweden, Denmark, and the Netherlands has reached design standardization, serialization of products, modular assembly, the industrialization of production, and standardized operation. In addition to using advanced anaerobic technology for biogas projects, high-quality biogas storage tanks are also required. Nowadays, there are more and more biogas storage tanks on the market, and more and more types, and Glass fused to steel tanks have gained the trust and recognition of more customers due to their unique advantages, and have gradually become widely used biogas storage tanks worldwide. Enamel assembled tanks are storage tanks assembled on the site from enamel steel plates, stirrups, self-locking bolts, sealants, and other accessories. They combine the strength of steel plates and the corrosion resistance of enamel. They have a short construction cycle, low cost and corrosion resistance. It has the advantages of excellent performance, convenient installation, and free expansion of the tank volume. It has a service life of up to 30 years and is the preferred biogas storage tank. Moreover, the surface of the storage tank is smooth and moist, bright and bright, and the color of the storage tank can be customized according to customer needs. Zhengzhong Technology's steel enamel technology is a high-end steel anticorrosion technology for the storage tank market. At the same time, Zhongzhong Technology is also the earliest and most experienced enamel manufacturer in Asia.
Prospects For The Development Of Bio-energy
Biomass energy has similar advantages to other renewable resources and has great prospects for development and utilization. First, reproducibility. Biomass energy is a kind of generalized solar energy resource. It is a product of photosynthesis and has permanent renewability. It is inexhaustible. Second, cleanliness. The sulfur content and nitrogen content of biomass are low, and the amount of carbon dioxide emitted when it is used as fuel is almost all photosynthesized by the biomass itself. Therefore, the net greenhouse gas emissions to the atmosphere are close to zero, which can effectively reduce the greenhouse effect. Third, reserves are abundant and widely distributed. As long as there is photosynthesis, there is biomass energy and abundant reserves. As mentioned earlier, biomass energy is the fourth largest resource in the world, after coal, oil and natural gas. Fourth, biomass is convenient and easy to obtain, low in price, and convenient for transportation and use. It is estimated that by 2020, the commercialization of biomass resources around the world will reach 100 million tons of oil equivalent, and the production capacity of bio-liquid fuels on a scale of 10 million tons will be formed. The potential for sustainable biomass energy is huge. If it is properly developed and utilized, it can meet more than 65% of the current global resource demand. It is obvious that the development prospect and potential of biomass energy as a renewable resource are huge.
