Description
Technical field
The present invention relates to technical field of active carbon, in particular to a kind of production technologies of active carbon.
Background technique
Active carbon, also known as activated carbon, activated carbon or activated carbon are black powder or granular carbonizable substance.Active carbon
Since microcrystalline carbon is irregular alignment in structure, there is pore between interconnection, carbon tissue defects can be generated in activation,
Therefore it is a kind of porous carbon, and bulk density is low, large specific surface area, and does the main material of a filter.Existing work
Property charcoal preparation process is complicated, raw material expend larger, there are some problems in actual production.
Summary of the invention
In order to solve the above technical problems, technical solution provided by the invention are as follows: a kind of production technology of active carbon, including with
Lower step:
(1) prepare raw material: timber, sawdust, tree root, fruit stone, shell are put into furnace vehicle by raw material mixed grinding, and by raw material,
And furnace vehicle is put into retort.
(2) retort is warming up to 20~150 DEG C, the moisture evaporation for adhering to raw material surface；Charing furnace temperature is risen to
175~275 DEG C, raw material is made to enter pre- carbonization stage, raw material is made to carry out pyrolytic reaction；Charing furnace temperature is risen to 300~400
DEG C, carbonize raw material, and be passed through vapor into retort and reacted；Charing furnace temperature is risen to 450~550 DEG C,
Calcine raw material, the impurity of discharge residual in the feed.
(3) active carbon that reaction obtains is entered in discharging cooler by the discharge port of furnace tail and is cooled down, put after cooling
Enter pulverizer to crush, examine, be packed and stored.
The present invention has sufficiently used the plant resources such as timber, sawdust, tree root, fruit stone, shell, has widened activated carbon raw material
Sources reduce the cost of material of active carbon, and method for preparation of active carbon of the present invention is easy, time-consuming shorter, manufactured
Active carbon finished products quality is higher.
