Abstract
The present invention relates to adsorbent, and belongs to the field of technology of treating water and air with active carbon. The present invention prepares active carbon with giant reed root and stem and through crushing, stoving, carbonizing, forming pore and activating. The prepared active carbon may be applied widely in eliminating aromatic compound and organic chloride from waste water, eliminating heavy metal ions, treating atmosphere pollution, etc. The giant reed has low carbonizing temperature and low power consumption.
Description
Technical field
The present invention relates to a kind of sorbent material, belong to gac water treatment and waste gas and obnoxious flavour and administer technical field.
Background technology
Gac has its exclusive characteristic as a kind of inorganic chemical product.It has very strong adsorptive power to the organic or inorganic material in gas, the solution etc., also can be used as filler simultaneously.Because it has unique pore texture and surfactivity functional group, enough chemical stabilities, physical strength and acidproof, alkaline-resisting, thermotolerance, and water insoluble and organic solvent, use superperformances such as the easy regeneration in back of losing efficacy, in the improvement of water treatment and waste gas and obnoxious flavour, have been widely used.
The gac of producing is divided into wooden and ature of coal two classes substantially at present.Some area is adopted to cut down forest and is produced gac, has caused broken ring of serious forest and soil erosion.Giantreed is a kind of per nnial herb, and stem is uprightly tall and straight, the likeness in form reed.The adaptive faculty of giantreed is very strong, also is easy to breeding, is widely distributed in China, North gets Liaoning, reaches Guangxi in the south, 3 years every M of living Rhizome of Giantreed
2About 35kg.It is drought-enduringly to have waterloggingly, promptly heat-resisting cold-resistant again, no matter is can both grow on the ground in swampland, flood land or wilderness.Root of giantreed and stem can carry out carbonization-activation as raw material, and some have the giantreed of terminal bud can be used for breeding new giantreed, do not have then can throwing away of terminal bud, become a kind of waste.If with its charing, then be the waste material utilization, solved the situation of China's production gac resource anxiety simultaneously.
Summary of the invention
The present invention is directed to the starting material deficiency of preparation gac, provide a kind of root of giantreed and stem of utilizing to carry out charing pore-creating, be made into gac and both solved the insufficient problem of current making gac starting material, the charing of the active giantreed charcoal that the giantreed waste material is utilized effectively and pore-creating preparation method again.
The present invention finishes by following technical measures: a kind of active giantreed charing and pore-creating preparation method are as follows:
1, charring process
Giantreed need be removed the impurity on surface before pulverizing, giantreed is crushed to the particle that particle diameter is 1.0 ~ 2.0cm, dries or dries.Descend dry 7 ~ 9h at 100 ~ 120 ℃ then in baking oven, dried giantreed secluding air in High Temperature Furnaces Heating Apparatus is heated to 340 ℃ ~ 360 ℃ constant temperature 1 ~ 2h and carries out charing, promptly gets the giantreed carbonized material;
2, activating process
With water vapour is that activator prepares gac, and the Rhizome of Giantreed carbonized material is added in the activation furnace, behind heat temperature raising to 100 ~ 120 ℃, feeds water vapour, is heated to 390 ~ 410 ℃, behind constant temperature 2 ~ 4h, treats that temperature reduces to normal temperature, shifts out activation products; Activation products after the washing are kept 7 ~ 10h drying under 100 ~ 120 ℃, obtain gac.
After the root of giantreed and stem pulverized, place the baking oven destructive distillation, the charing in High Temperature Furnaces Heating Apparatus of the giantreed after the destructive distillation.Be raw material with the giantreed carbonized material then, water vapour is that activator activates in activation furnace, obtains active giantreed charcoal.
The present invention has the following advantages:
(1) adopts Rhizome of Giantreed and stem as raw material, after high temperature carbonization pore-creating, become gac, can be widely used in aspects such as aromatics, organic chloride waste water control and removal of heavy metal ions;
(2) can be used for the prevention and control of air pollution aspect, as toxic gases such as absorbing formaldehydes;
(3) be used as biofilm packing, the carbonization temperature of giantreed is low, and energy consumption is low.
