Embodiment Construction

[0015] The production process of the present invention comprises the following process steps:

[0016] 1. Raw material selection process: use 5-8-year-old moso bamboo, saw it into 2-2.5 meters oblong bamboo tube, dry it in the shade for 4 days and install it in kiln;

[0017] 2. Raw material kiln loading process: according to the diameter, the round bamboo tube is placed upside down in the kiln from the inside to the outside, the inside is thick and the outside is thin, and the kiln door is closed, leaving a small burning and steaming port;

[0018] 3. Smoke dehydration process: use fuel to burn in the fire inlet, control the internal temperature at 25°C-105°C (about), and use flue gas to smoke for 8 days to dehydrate;

[0019] 4. Dry distillation and carbonization process: after the previous process, the moisture of the original bamboo has been completely discharged. At this time, the temperature continues to rise to 150°C-300°C. The bamboo charcoal is carbonized by dry disti...

Abstract

An activated bamboo carbon is prepared from choosing raw material, loading raw material in kiln, smoking for dewatering, dry distilling for charring it, refining, spraying steam and sealing kiln. Itsadvantages are physically activating it thoroughly, high adsorbability and electric conductivity, high output rate and no environmental pollution.

Description

technical field [0001] The invention relates to a charcoal burning technology, in particular to a production process for firing bamboo activated carbon. Background technique [0002] When exposed to activated carbon in real life, charcoal is mainly used as raw material, through secondary combustion, activated by flue gas, from wood to black carbon, the utilization rate is only 28%, and in the second activation process, a large number of carbon molecules escape For every three tons of charcoal, only one ton of activated carbon can be recovered, which consumes too much resources. There is a kind of chemical method to prepare activated carbon, the recovery rate is slightly higher, but the waste water produced is seriously polluted, which affects environmental protection. The invention patent application with the retrieval application number of 98115886.2 discloses a special technique of bamboo charcoal. However, the properties of bamboo charcoal, suc...
