The use of garbage to produce charcoal, tar and gas is to separate the combustibles (domestic sewage sludge too) and non-combustibles in garbage using liquid separation, in which the combustibles are dry distilled to obtain charcoal, tar and gas without producing dioxin (poison
King). Non-combustible materials can be separated from glass, coal ash, bricks, stones and waste batteries, glass can be recycled, coal ash can be used as fertilizer, bricks, stones can be used as building materials, waste batteries after crushing, high-temperature melting, according to
various metals with different melting points and separated from different metals, so as to achieve recycling. Charcoal can be gasified to produce hydrogen, methane, etc. because coal can be gasified. Charcoal can also be liquefied to produce gasoline, diesel, and other oils, also
because coal liquefies to produce oils. Coal gas has hydrogen, methane, traces of carbon monoxide and carbon dioxide. Hydrogen and methane can be separated using variable pressure adsorption, and hydrogen can be used in fuel cells to generate electricity, and methane liquefied for other uses
(such as lighters). Gas generators can also be used to generate electricity, and gas can also be used to produce methanol. Tar contains wood acid, wood tar, and wood pitch. Using distillation, the chemicals in tar can be separated out, such as methyl
acid and methanol. There are also valuable pharmaceutical raw materials. All of the above separation production units are available in China. Yunwei Group has dry distillation, coal gasification, coal separation device, Kaiyuan Decomposition Company has coal liquefaction device. Northeast Jilin, Hunan has scrap metal
recovery device. Has been patented, a day to deal with 4000t of garbage, the production of methanol 350t (gas 1.4 million m? power generation of 2.8 million degrees)
, 800t of wood acid, wood tar 400t, 800t of charcoal, power generation of 1.6 million degrees. Production of 1t methanol consumption: electricity 840KWh, water 8t, steam 1t, gas 3200m?
Hair 1KWh consumption: consumption of charcoal 350~400g, water 3kg. in the process of urbanization, garbage as a product of urban metabolism was once the burden of urban development, many cities in the world have had a garbage siege situation. Nowadays, garbage is regarded as the most potential and inexhaustible "urban deposit" and "misplaced resources". This is not only the deepening of the understanding of garbage, but also the inevitable requirements of urban development.
China is a large agricultural country, the arable land area of more than 1.8 billion
mu, every year there is a rich amount of straw produced. According to the survey, in 2009, the national crop straw theoretical resources of 820 million tons (air-dried, moisture content of 15%). In terms of varieties, rice straw amounted to about 205
million tons, accounting for 25% of the theoretical resources; wheat straw amounted to 150 million tons, accounting for 18.3%; corn stover amounted to 265 million tons, accounting for 32.3%; cotton stalks amounted to 25.84
million tons, accounting for 3.2%; oilseed crop stalks (mainly rapeseed and peanut) amounted to 37.37 million tons, accounting for 4.6%; and legume straw amounted to 27.26 million tons, accounting for 3.2%. 27.26 million tons, accounting for 3.3%; potato straw is 22.43
million tons, accounting for 2.7%. Such a huge amount of biomass straw, due to the lack of good technology to utilize, still most of the waste and incineration. This has not only caused a heartbreaking waste of resources, but also brought about the deterioration of the environment (atmosphere, water quality and
soil) with an inestimable impact. At this stage, countries around the world are focusing on the comprehensive utilization of agricultural and forestry waste biomass (crop residues), especially in North America and Europe. The utilization pathway mainly focuses on energy, feed and
fertilizer three aspects. Our government also attaches great importance to, and spares no effort to support and promote the comprehensive development and utilization of straw. In 2006
The No. 1 document in the requirements of the focus on the promotion of agricultural development of waste comprehensive utilization of technology, this financial investment alone amounted to hundreds of millions of dollars. However, due to the imperfect policy, low level of research and development, some key technologies are difficult to break through,
the results are very little, the 2001 figures mentioned that about 400 million tons of straw is discarded every year[2]
most of the straw that is roughly utilized is only used for cooking, raising livestock, building sheds, heating and fertilizing the fields, and so on.
Although, the structure of energy use in rural life in China has changed to some extent, biomass such as fuel wood and straw still accounts for more than 50% of the total energy consumed, and is the main energy source in rural life. However, plagued by technical bottlenecks at this stage of biomass collection
means, transportation methods and the level of efficient conversion and utilization, today in 2013 is still mainly to direct combustion heating heating, not only thermal conversion efficiency is low (energy utilization rate of only about 15%),
and serious pollution of the environment, resulting in urban areas PM2.5
exceeded the standards and reduced visibility in rural areas, etc. Baoding Fangzheng Machinery Factory produces complete sets of garbage pre-treatment (i.e., sorting) equipment, which is mainly used for the sorting of informal stale domestic garbage that has been landfilled in the city for many years and the sorting of fresh domestic garbage in the concentrated places
of garbage. The garbage sorting and processing equipment can sort the domestic garbage into four major parts such as combustible materials, organic soil, recycled materials and stones. In the case of not on the depth of the treatment device, the use of combustible incineration, 20m/m
below the organic soil for landscaping, recyclable materials recycling (such as waste plastics used to make secondary plastics), stone used as building materials and other simple methods of treatment, can make the waste to achieve the reduction of quantities, resources, harmless, and so that the treatment
after the garbage pit of the land used in the urban construction or a pit repeated The goal of burying garbage. Baoding Fangzheng garbage sorting and classification treatment equipment is developed from the requirement that the comprehensive treatment of garbage must first be sorted, which includes four parts: crushing, sorting,
transferring and packing, all of which are produced by the plant.
High-value comprehensive utilization of biomass straw resources, has been China's current stage of agricultural structural adjustment and rural economic development
a major issue. The main component of plant biomass is lignocellulose, which is the only predictable sustainable resource in the world that can provide material and fuel for human beings. The total amount of biomass produced globally is about
2.9×1021
joules of energy per year, but the utilization rate is only nearly 7%. How to achieve high-value comprehensive utilization of biomass resources, which is a major historical mission given to the global scientific and technological workers in related fields, time is running out, opportunities and challenges exist side by side. In fact
Agro-forestry biomass waste (crop residues, forest processing trimmings, etc.) is a valuable resource for the conversion of biomass energy (solid fuel, fuel ethanol, biobutanol, biodiesel, aviation fuel, anaerobically digested biogas, biomass pyrolysis gas, biomass power generation, etc.), biobased materials and functional chemicals. If based on the proposed construction of the comprehensive utilization of agricultural and forestry biomass resources innovation platform and continuous multi-port flash explosion as the leader of the technical support system, the
valuable biomass resources into high-value-added products (pulp, wood-plastic panels, feed, fuels, functional health food and high-purity special drugs, etc.), it will not lose a stabilization of the current era of the basic agricultural
industry status It is a new measure to stabilize the status of basic agriculture, properly solve the problem of three rural areas, drive the sustainable development of related industries, stimulate the local economy, improve the ecological environment of villages and towns, promote the construction of a new socialist countryside, develop a circular economy and create a green ecological industry chain
Measures. As a pre-treatment of agricultural and forestry biomass waste as a realistic and feasible means, steam (gas) body flash technology shows high efficiency, rapid and suitable for large-scale treatment of unique advantages. The use of inexhaustible agricultural and forestry waste
Biomass production of fuels and petrochemicals is an important research direction of green chemistry, but also the petroleum refining and petrochemical industry to achieve sustainable development of the road. Following the pharmaceutical biotechnology, agricultural biotechnology, biotechnology
Industrial development has now entered the industrial biotechnology stage, the core part of which is biorefinery, that is, the use of biomass to produce energy and a variety of chemical products and biomaterials, the development of this technical field of development of the country attaches great importance. Biomass is
renewable energy, but also to produce thousands of chemical products, and because of its main component of carbohydrates, in the production and use of the process and environmentally friendly, but also better than fossil energy. In addition, it is crop straw, animal manure,
forestry waste, organic waste and other agricultural and forestry waste and environmental pollutants as raw materials, so that it is harmless and resourceful, the plant stored light energy and material resources in depth development and recycling, can be said to be a model of circular economy.
Biomass resource conversion and utilization has become one of the world's major hot topics, by the world's governments and scientists
Wide attention. The United Nations Development Program (UNDP), the World Energy Council (WEC) and the U.S. Department of Energy (DOE) have all taken biomass as the primary choice for the development of renewable energy. The modern biomass
industry is an emerging industry of particular interest that utilizes crops, trees and other plants and their residues, animal and poultry manure, organic waste and other renewable or recycled organic materials as raw materials, and produces biomass chemicals, biofuels and bio
energy as well as bio-based functional materials through industrial processing. Although the development of the biomass industry will enable mankind to stop relying too much on fossil energy, the "sugar economy" based on biomass as feedstock in 2013 still lacks the strength to
compete with the "hydrocarbon economy" based on oil and gas. Although the cost of biomass raw materials is low, but the cost of processing and conversion is high, only to achieve technological breakthroughs, in order to form a complete biomass technology engineering system. At present, I
Country has been a biotechnology power, many products in the world's first production, however, the technical and economic indicators of these products are relatively backward, the need to develop through efforts to become a biotechnology powerhouse. Dr. Ri
Fujin, a U.S. strategic economic analyst, pointed out in "The Century of Biotechnology" that the century of biotechnology could also be the century of the Chinese, and hoped that China would play an important role in the century of biotechnology. Experts believe that China has the conditions for bio-energy and bio
materials scale industrialization and industrialization, can be formed in 2020 the output value of the scale of trillions of yuan, in the "oil depletion inflection point" is approaching the formation of part of the substitution capacity.
