The production process changes waste, namely the eupatorium adenophoor cooling and purifying; and 6, carrying out stuffy kiln to obtain machine processed charcoal and eupatorium adenophorum wood tar. The production process changes waste, namely the eupatorium adenophorum, into valuable, and has high utilization value.rum, into valuable, and has high utilization value.

Description

technical field [0001] The invention relates to comprehensive utilization of Eupatorium adenophorum, in particular to a production process for comprehensive utilization of Eupatorium adenophorum. Background technique [0002] Eupatorium adenophorum, the top ten invasive species in China, is widely distributed in Guangxi, Hainan, Sichuan, Tibet, Guizhou, Yunnan, Chongqing, Hubei, Taiwan and other provinces, and its origin is from Mexico to Costa Rica in the Americas. Around the 1940s, Eupatorium adenophorum was introduced to southern Yunnan from the China-Myanmar border. In recent years, due to its strong growth and adaptability, it has encroached on my country's ecological and economic resources. By the end of 2008, Eupatorium adenophorum in my country The Zeilan damage area has reached more than 222 million mu, causing economic losses of nearly 10 billion. The hazards of Eupatorium adenophorum are mainly manifested in the following aspects: [0003] 1. Destruction of anima...

AI Technical Summary

Problems solved by technology

[0005] 2. Destruction of agricultural production

Eupatorium adenophorum has strong absorption of soil nutrients, which will greatly deplete soil fertility and seriously damage soil arableability

[0007] 3. Destroying the structure of local vegetation communities, affecting gardens and tourism landscapes

The harm of Eupatorium adenophorum to forestry is that it invades barren hills suitable for forest, affects afforestation, tree growth and natural regeneration of logging sites; invades economic forest land, affects the growth of tea, mulberry, and fruit, and doubles the management intensity, consuming a lot of manpower and resources. funding, and seriously threaten the development of commercial crops

[0009] 4. Harm to human health

[0020] (1) The traditional machine-made charcoal production method is still used. In the production process, the flammable gases such as CO and the polluting by-products of wood tar steam produced in the rod making process and carbonization process are directly discharged into the air and cause great pollution to the environment. ;

[0021] (2) Eupatorium adenophorum is a poisonous plant and contains a large amount of organic toxins. If the traditional production process is adopted, the volatilization and pyrolysis products of these toxins in the process of rod making and carbonization will make the pollution more serious, and it will also cause serious pollution to the production personnel. cause great harm

[0023] (4) The existing drying technology can only dry grass powder, and the moisture in the inner layer of the grass section cannot be completely eliminated

[0035] (1) The production process is complicated, the production cycle is long, and the production cost is too high

[0036] (2) The detoxification problem of Eupatorium adenophorum has not been completely solved, and a large amount of Eupatorium adenophorum toxin remains in the dry residue

[0037] (3) The organic matter in Eupatorium adenophorum is obtained by means of organic extraction, the production cost is high, and the organic extract remaining in the slag of Eupatorium adenophorum is discharged into the atmosphere during the process of dehydration and final drying. will cause environmental pollution

[0038] (4) During the drying process, the ethanol remaining in the dehydrated dry slag is flammable. If the air intake of the dryer temperature cannot be well controlled, the dry slag may be ignited or even explode.

[0039] (5) The traditional machine-made charcoal production method is still used, and the flammable gases such as CO and polluting by-products such as wood tar vapor produced during the rod making process and carbonization process are directly discharged into the air, causing great pollution to the environment

[0040] (6) Since this process only extracts the chlorogenic acid in Eupatorium adenophorum, and a large amount of organic toxins remain in the dry residue, if the traditional production process is followed, these toxins will be volatilized and decomposed during the rod making and carbonization process. The products after pyrolysis will seriously pollute the environment and also cause great harm to production personnel
