AI Technical Summary

Problems solved by technology

In particular, Jiangxi, Fujian, Zhejiang, Anhui, Hunan and other provinces are the main moso bamboo production areas in my country. The waste after processing moso bamboo reaches more than 800,000 tons every year. At present, most of them can only be used as ordinary fuels and cannot be fully utilized.
[0003] Due to the high wax and oil content of moso bamboo waste and high material density, it is difficult to prepare high-performance products by traditional technology. At present, most activated carbon manufacturers in my country are still unable to use moso bamboo waste as raw materials to manufacture high-performance activated carbon by traditional technology.

Embodiment 1

[0031] Take 10 kg of moso bamboo powder with a mesh number of 60-80 mesh, add 12 kg of 15% zinc chloride solution, mix in a rotary mixer for 40 minutes, move to a stainless steel tray, put it in a drying oven, and heat it at 95 ° C. Dried under high temperature for 26 hours, moved into a slaking furnace, and slaking at a temperature of 160-170° C. for 65 hours to obtain about 5 kilograms of clinker bamboo powder. Clinker bamboo powder is moved in the kneader, adds 5% polyvinyl alcohol solution 300ml, 55% zinc chloride solution 4500ml, fully mixes and kneads for 90 minutes. The kneaded material is granulated in an extrusion granulator to obtain a ￠2.5mm product, which is dried in an oven at 80°C±2°C for 60 minutes and then screened. The screened products are carbonized in an electrically heated stainless steel converter at a carbonization temperature of 225°C±5°C for 48 hours. After the carbonization is completed, raise the furnace temperature to 475°C±5°C, keep it for 45 minu...

Embodiment 2

[0035]Take 10 kg of moso bamboo powder with a mesh size of 60-80 mesh, add 14 kg of 30% phosphoric acid solution, mix it in a rotary mixer for 50 minutes, move it to a stainless steel tray, put it in a drying oven, and dry it at 95°C After 30 hours, move it into a slaking furnace, and slaking at a temperature of 180-190° C. for 50 hours to obtain about 5 kilograms of clinker bamboo powder. The clinker bamboo powder is moved to the kneader, add 250ml of 5% polyvinyl alcohol solution, 4000ml of 70% phosphoric acid solution, fully mix and knead for 60 minutes. The kneaded material is granulated in an extrusion granulator to obtain a ￠2.5mm product, which is dried in an oven at 80°C±2°C for 60 minutes and then screened. The screened products are carbonized in an electrically heated stainless steel converter at a carbonization temperature of 210°C±5°C for 60 hours. After the carbonization is completed, raise the furnace temperature to 450°C±5°C, keep it for 45 minutes, cool to 120...

Embodiment 3

[0038] Take 10 kg of moso bamboo powder with a mesh size of 60-80 mesh, add 15 kg of 25% zinc chloride solution, mix in a rotary mixer for 50 minutes, move to a stainless steel tray, put it in a drying oven, and heat it at 95 ° C. Dried under high temperature for 30 hours, moved into a slaking furnace, and slaking at a temperature of 180-190° C. for 50 hours to obtain about 5 kilograms of clinker bamboo powder. Clinker bamboo powder is moved in the kneader, adds 5% polyvinyl alcohol solution 250ml, 70% phosphoric acid solution 4000ml, fully mixes and kneads for 60 minutes. The kneaded material is granulated in a centrifugal spherical granulator to obtain a ￠6-20 mesh product, which is dried in an oven at 80°C±2°C for 60 minutes and then screened. The screened products are carbonized in an electrically heated stainless steel converter at a carbonization temperature of 190°C±5°C for 60 hours. After the carbonization is completed, raise the furnace temperature to 430°C±5°C, keep...
