Earlier this year, Jiangsu Hehai Equipment Co., Ltd. and United States University of Atlanta professor Dr. Zhicheng Wang signed a joint cooperation agreement for the development of complete sets of equipment for the preparation of waste derived fuels and organic compound fertilizers. This set of anaerobic pyrolysis solid waste comprehensive treatment system has been developed into a systematic project of process technology development, complete equipment supply, comprehensive recovery and treatment, and joint investment and operation. It has become a harmless treatment and disposal of urban domestic garbage in China. The mature technology for the recycling of materials has become a nationalized core technology and equipment with a number of independent intellectual property rights and technological innovation achievements. At present, the overall technical equipment of the system reaches the domestic leading level.
With the rapid development of the global economy and the continuous improvement of human production and living conditions, the accompanying municipal solid waste has become a catastrophic problem of international concern. In order to reduce the large backlog of solid waste and further implement the recycling of waste, many countries have spared no effort in the long-term to explore a good strategy for integrated waste disposal. The treatment and comprehensive utilization of urban garbage has become an urgent and major target for the political, economic and scientific and technological circles in the world.
The anaerobic pyrolysis solid waste treatment system is based on a comprehensive survey of the generation, structure, reserves, and processing technologies of global urban waste, and it is based on the reduction, recycling, and harmless disposal of urban waste by the International Environmental Organization. The requirements of the solution include the serialization of process technology and complete sets of equipment developed through the integrated principles of the physical, biological and chemical fields. Wang Zhicheng introduced that the current international governance methods mainly include biochemical treatment methods, underground landfill methods, and incineration power generation methods. Practice has proved that the former two methods have serious shortcomings such as long-term occupation of large-area land, polluting air and water sources, causing secondary pollution, and breeding pathogenic viruses. The implementation of waste incineration and power generation has high costs and low efficiency, and there are corresponding problems such as polluted atmosphere, large amount of residue, heavy metals and a large amount of available resources. Particularly serious is that the waste incineration process will produce a large number of harmful substances such as dioxins, which are strong carcinogens that are difficult to degrade in the natural environment. The harm to human health is extremely serious.
In order to seek an effective treatment plan for solid waste, Wang Zhicheng participated in the research of a new type of catalytic reforming process at the National Renewable Energy Laboratory in the United States from 1993 to 2000, and conducted a large number of experiments to convert organic waste into fuel. . On the basis of breakthrough scientific research achievements, another pilot plant was established in Georgia from 2000 to 2007 in the United States for seven years. The scale-up production process directly produces clean fuel and efficient fertilizer from organic waste. Development research. On the basis of further substantive results, Wang Zhicheng decided to go back to the mainland of China for promotion and application, and adopted this mature technology to preside over the construction of a solid waste treatment plant with a daily treatment capacity of 150 tons in Pinghe County, Fujian Province. Eat “locally collected municipal solid waste, and successfully use waste waste resources to mass produce fuel oil and slow-release organic compound fertilizers that are generally applicable to farmland, and realize the harmless treatment of urban garbage.
The main components of urban living garbage are large amounts of waste generated from catering, slaughterhouses, aquatic products markets, fruit market, urban logistics, citizens and household life wastes, tourist attractions and commercial flow fields, etc., and organic matter accounts for more than 2/3 of them. The resource utilization rate is extremely high. The anaerobic pyrolysis process is to pyrolyze the organic matter in the domestic waste to form various organic gas and solid organic carbon, and then transforms and absorbs harmful substances such as chlorine, sulfur, and mercury through a filtration recovery process, and converts it into a catalytic converter. Sodium chloride, sodium sulfate, zinc oxide and other recyclable substances. Removal of harmful gases into the catalytic reforming process, the production of H2, CO, CO2, CH4 and other mixed gases, will be sent to the synthesis process to form a fuel mixture, can be divided into gasoline, diesel, paraffin and including CO2, CO, CH4 and steam are mixed exhaust gas. After the mixed exhaust gas is recycled, it will be gradually absorbed. The solid organic carbon enters into the chemical fertilizer synthesis process and undergoes the synthesis reaction of related complexes to produce a highly effective organic slow-release compound fertilizer suitable for farmland and in short supply.
The process of anaerobic pyrolysis of solid waste and recycling of resources must be completed through strict process technology and sophisticated and consistent complete sets of equipment. The recycling of solid waste must first undergo a multi-level screening and crushing to cut various organic mixtures into fine particles. The pyrolysis process must be carried out in a fluidized bed at a temperature of 500°C to 1000°C under a specific pressure difference, and then decomposed and precipitated by a number of processes such as polymerization of various catalysts and slurry Fischer-Tropsch synthesis, etc.; Recycling of the intermediate products of vapor, liquid and liquid, and inert residues modified by thermal energy, used in the construction of bricks and building infrastructure, bridges, embankments, culverts and other basic facilities.
Wang Zhicheng pointed out that the anaerobic pyrolysis solid waste treatment system is the product of international joint development and cooperation innovation. Its independent innovation is first embodied in high-speed, high-efficiency and continuous operation. The harmless pyrolysis treatment process of wastes is carried out within 20 minutes. Intelligent and pipeline operations are implemented. The application efficiency is high and the energy consumption is low. The second is the effective implementation of garbage harmless treatment. Continuous process, complete set, automation, full closure, high temperature sterilization and deodorization rate of 100%, to avoid leakage of pollutants, implementation of clean production, eliminate secondary pollution. Third, it can effectively implement the comprehensive utilization of turning waste into treasure, and the effective resource utilization rate of dry solid waste in cities is close to 100%. Synthetic fuel is a sulfur-free, sterile, high-efficiency pure fuel, and the slow-release compound fertilizer produced is ecologically clean. , harmless organic fertilizer, crops absorb quickly, with the function of lifting the agglomeration of the soil and improving the soil. The recycling process of the entire solid waste has met the high-level requirements of international reduction, harmlessness, and resource utilization.
It is understood that Fujian Pinghe waste treatment application process is led by Wang Zhicheng. The key equipment of the system is independently developed and manufactured by Jiangsu Hehai Equipment Company. Since the company was put into operation in June 2010, it has treated and degraded 12,000 tons of municipal solid waste, and used 300 million tons of inorganic building materials as an effective slow-release organic compound fertilizer. More than 5,500 tons, creating a ton of waste half tons of organic fertilizer waste resource utilization value. The effective resource utilization rate of dry solid waste is close to 100%, and the project investment is only 1/2 to 2/3 of the domestic incineration power generation project.
The system's leading equipment includes auxiliary equipment before solid waste treatment, including cracking equipment for packaging materials, metal magnetic separation equipment, vibration screening equipment for waste hardware, organic material cleaning and sewage discharge equipment, and solid grading and crushing equipment for the waste treatment process. The company has more than 30 sets of combined equipment such as granulation equipment, wet-drying equipment, screening and packing equipment, compound fertilizer synthesis equipment, and waste-derived fuel catalytic preparation.
In the application of many devices, the fragmentation of waste is an important factor in determining the efficiency of treatment and the comprehensive utilization effect, and the level of solid waste is broken, which is the bottleneck that has not yet achieved breakthroughs at home and abroad. Urban garbage contains various kinds of hard inorganic materials such as metal, stones, tiles, glass, and cement mortar. It also contains fiber software such as cotton yarn, cloth, wood, plastics, chemical fiber, and hair. It is extremely difficult to implement comprehensive crushing technology. The LSF crusher independently developed by Hehai Equipment consists of a drive system, a cutting system and a control system. Its drive system adopts a self-developed continuum transmission structure; the cutting system adopts a unique dual-axis multi-combination spiral cutting patented technology; to ensure the cutting accuracy and efficiency, the balance shaft and spiral structure blade of the grinding equipment adopts a special formulation of carbide steel. Production, its sharpness, wear resistance, anti-corrosion performance, anti-fatigue strength, etc. have reached the international advanced level. The entire system is implemented with program control, and various types of domestic garbage can be crushed and cut into fine particles according to a set procedure and transferred to the next process. Today, Hehai Equipment Co., Ltd. has only obtained four technical patents for the broken equipment system.
Ding Yongzhi, general manager of Jiangsu Hehai Water Supply and Drainage Equipment Co., Ltd., said that the anaerobic pyrolysis waste treatment system is currently the leading environmental protection technology and equipment in China. They will report this important international innovation achievement to the national major special projects as soon as possible so that they can Medium-sized cities and even small towns are widely used.
