The project uses local agricultural and forestry wastes to produce methane-based biomass gas through dry distillation technology, and then supplies the biomass gas to villagers for cooking, and the by-product charcoal is used for heating or food barbecue. The project not only shows the utilization of renewable energy, but also reduces the environmental pollution caused by agricultural and forestry wastes and improves the rural appearance. The total investment in civil engineering and equipment installation of this project is 2.7 million yuan (including 300,000 yuan for gas bath).
At present, the transformation methods of biomass energy in the world include physical transformation, biological transformation and chemical transformation. Biomass energy conversion technologies mainly include biomass direct combustion, biomass solidification, biomass fermentation, biomass liquefaction and biomass pyrolysis and gasification. The common technology for producing gas is biomass pyrolysis gasification, including aerobic pyrolysis gasification and anaerobic pyrolysis gasification.
Aerobic pyrolysis gasification technology of biomass can greatly improve the calorific value of biomass gas, the experimental calorific value can reach more than 8300KJ/ m3, and the gas production rate can reach more than 1.2 m3/kg. However, the process flow is complex, and the investment and operation cost are relatively high, so it is suitable for short-distance boiler combustion, drying and power generation, and not suitable for rural use and promotion.
There are many kinds of anaerobic pyrolysis gas production. Conventional pyrolysis can be used in rural areas with simple technological process and convenient operation and maintenance. The calorific value of pyrolytic biomass gas can meet the requirements of national artificial gas production, reaching 3800-4800 kcal (the calorific value of ordinary straw gas is only 1000 kcal), the gas production rate is about 0.35 cubic meters/kg, and a considerable number of by-products can be produced. Every 1000 kg of biomass can produce 350 cubic meters of combustible gas, 300 kg of charcoal and 50 kg of tar (the by-product of ordinary straw gas is only plant ash). This anaerobic pyrolysis gas production process was adopted in Lijiachang village of our town.
Anaerobic pyrolysis technology absorbs the advantages of various biomass gasification processes at home and abroad, and is a new technology and equipment suitable for small rural gasification stations (100 households). The anaerobic pyrolysis gas production process in Lijiachang Village of our town embodies the following characteristics:
The first is security. Straw pyrolysis gas is an artificial gas mainly composed of methane, hydrocarbons and hydrogen, which is flammable and explosive. Gas enters residents' homes through the pipe network, and once an accident occurs, it will cause huge property losses and personal injuries. Therefore, safety issues are mainly considered in the design. According to this principle, the heat value of straw gas produced by the selected straw gas manufacturing technology should be as high as possible, and the flame is not easy to extinguish and the straw gas leakage accident is not easy to occur. The carbon monoxide content of straw gas used should be as low as possible to reduce the harm to people's lives and property when straw gas leaks. The quality of straw gas is produced in strict accordance with the relevant quality standards stipulated in the National Artificial Gas (GB13612-1992) and the Technical Conditions and Acceptance Specifications of Straw Gasification Gas Supply System (NY/T443-200 1) promulgated by the Ministry of Agriculture, and the basis for the construction of the transportation pipeline network.
The second is the economy. The production of straw gas inevitably needs to consume some resources such as raw materials, including some electric energy, especially in rural areas. Through technical means, the operation cost and gas supply unit price will be reduced as much as possible, and the economic burden of villagers' gas consumption will be reduced. This process can produce charcoal, wood vinegar and tar, three by-products with certain added value, which greatly relieves the economic pressure of gasification station operation.
The third is reliability. Because this project is built in the most basic rural areas, the reliability of technology and equipment is very important. Now, all the people who are responsible for the operation and maintenance of the gasification station are villagers, and their cultural quality is relatively low. This equipment and technology are simple, stable and reliable, and are suitable for rural use.
The fourth is conformity. The low calorific value of this process is 15-20MJ/ m3, which is higher than the national standard 14.7MJ/ m3. Tar and dust are 5- 10 mg/m3, which is lower than the national standard10mg/m3; No harmful substances such as carbon dioxide, ammonia and naphthalene were detected, which were lower than the national standards of 20, 50 and 50 mg/m3 respectively. The oxygen content is 0.8v%, which is lower than the national standard 1v%. The carbon monoxide is 15- 17v%, which is lower than the national standard of 20v%. Liu Jiachang Village is located in the south of Weishanzhuang Town, adjacent to Pang 'an Road and facing Xingming Lake Resort and Forest Park in the south.
