Crop straw biomass honeycomb coal is mainly made from corn straw, cotton straw, wheat straw and rice husk by biological carbonization. This product is flammable, instant-burning, smokeless, tasteless, pollution-free, residue-free, not easy to crack, regular in shape, with carbon content above 80%, calorific value of 4300-6 100 kcal, renewable, and emits a small amount of SO2 when burning.
The calorific value of corn stalk is about 0.7-0.8 times that of coal, that is, 1.25 tons of corn stalk carbonized raw material is equivalent to 1 ton of coal. The combustion efficiency of corn stalk biomass honeycomb coal is 1.3- 1.5 times that of coal-fired furnace, so the heat utilization rate of 1 ton of corn stalk biomass honeycomb coal is equivalent to one ton of coal.
Carbonization is an important means to improve the utilization value of straw biomass honeycomb coal, and its main performance indexes such as mechanical strength, calorific value and semi-coke content are directly determined by carbonization method and carbonization process. Main characteristics of straw biomass honeycomb briquette
It uses internal thermal carbonization method instead of charcoal burning method and external thermal carbonization method, which is superior to the first two methods: 1, and the volatile content is12-18%; 2. Fixed carbon content > 80%; 3. Toner:1.0—1.3%; 4. Color: the section has metallic luster; 5. calorific value (j/g): > 31000; 6. The carbonization yield is 30-50%; 7. The carbonization cycle of a single furnace is shortened: 8 hours/furnace, and the carbon content of straw is uniform; 8. Environmental pollution: almost smokeless.
1, crop straw biomass honeycomb coal is a "green" civil fuel to replace traditional coal, liquefied gas and other high-quality people.
2. The tail gas produced by carbonization of raw materials can be made into straw vinegar products, which can be used for deodorization, anti-bird flu and pesticides in aquaculture and public places.
3. The temperature of the carbonization furnace is as high as 200-500 degrees, and it needs to be collected by circulating pipes to provide heating or hot water for the home.
4. Cupola and boiler, which are widely used in industry, consume a lot of firewood for ignition, and the price of firewood is much higher than that of coal. It is more economical to use straw biomass honeycomb coal instead of chopping wood to burn coal.
5. Straw biomass charcoal can be further processed into activated carbon, which can be widely used in pharmaceutical, chemical and other industries. It can also be used for sewage treatment. With the strengthening of environmental protection, the amount of activated carbon needed to purify wastewater and waste gas will increase.
1. Raw materials are crushed, carbonized, shaped and put into storage.
2. Determination of raw material source and production scale
The product is made by mixing and stirring more than 70% straw carbon powder and 30% common additives and then extruding. The raw materials are corn straw, cotton straw, wheat straw, rice husk and peanut shell in rural areas. The project is rich in raw materials and has a wide range of sources.
3. Basic colors and specifications of products
1) The specifications of straw honeycomb coal are the same as those of honeycomb coal produced by coal, and they are all black;
2) Straw biomass fuel ball, the size of table tennis, black;
3) Straw biomass fuel particles, slightly longer than pellet feed, are also black.
This project uses crop straws, especially corn, cotton, wheat and peanut shells as raw materials to produce straw biomass honeycomb coal, a high-grade civil fuel. Straw biomass honeycomb coal is becoming a global "green gold" industry and is gradually becoming a substitute for traditional "black gold" energy. In 2000, the United States began to implement the bill of "developing and popularizing biomass products and bioenergy", and the US government will use one billion tons of biomass energy for liquefaction and carbonization to replace traditional oil and coal. China has a population of more than 65.438+0.2 billion, most of whom live in rural areas and small towns. The main way to use energy for living is direct combustion. The rapid rise and development of small and medium-sized enterprises and private enterprises not only promoted the development of rural economy, but also accelerated the consumption of fossil energy, especially coal. Therefore, it is the best choice to develop straw biomass honeycomb briquette instead of combustion. It is listed as "Biomass Solidification Molding Fuel" in the Guidance Catalogue for the Development of Renewable Energy Industry compiled by the National Development and Reform Commission.
At present, the price of coal on the market is around 700 yuan/ton. Honeycomb coal made of coal, mixed with 30% loess and lime, costs about 0.30-0.32 yuan each, and needs firewood to ignite. The cost of adding binder to crop biomass fuel charcoal is about 90 yuan/ton, and the carbon powder content is above 80%. Each ton of straw charcoal can produce 3000 pieces 100×85mm household honeycomb charcoal, each piece can burn for 80- 100 minutes, which can be ignited by newspapers. It has low price, environmental protection and safety, and has strong competitiveness in the market.
Compared with other straw utilization projects in terms of production cost and investment effect, this project uses corn straw, cotton straw, wheat straw and peanut shell, which are rich in resources in China, to produce straw biomass honeycomb coal, with wide sources of raw materials, guaranteed technology, less investment, quick effect and basically no risk. For example, a township can build 1-2 straw biomass fuel carbon plants, which can digest 1/3 of corn straw, cotton straw and some wheat straw and peanut shells in the whole town.
Take the production of straw biomass honeycomb coal as an example, 3-4 people can produce 4-6 tons per day, and the cost per ton is 200 yuan, which is calculated according to the ex-factory price of 700 yuan per ton (the current market price is 600-800 yuan/ton, 3000 pieces per ton, and the price per piece is between 0.25-0.30 yuan). Daily net profit1above 500 yuan.
