Description
Technical field
The present invention relates to a kind of acticarbon, the acticarbon and its preparation process of phosphoric acid are especially loaded,
Belong to technical field of waste gas treatment.
Background technology
Ammonia (NH3) it is a kind of colourless, irritant and corrosive gas, it is that N is removed in air2And NO2It is most abundant in addition
One of compound containing N.In annual global range, artificial synthesized NH3Yield estimate up to 4.5 hundred million tons.NH in air3Content
More than 50ppm, you can generate apparent smell, strong impulse can be generated to eye, nose, larynx after people's sucking.U.S.'s employment security
It is provided with administration of health general administration (OSHA), in NH3Working time day that concentration reaches in the environment of 50ppm must not exceed 8h or
Work hours per week are no more than 40h.
The NH being presently used in processing industrial tail gas3Or reduce its discharge method include catalytic decomposition, with other gases
Reaction, solid matter absorption and fractional combustion etc..In these techniques, adsorbed using solid matter adsorbent (such as activated carbon)
NH3, due to its equipment economy and easy to operate, become a kind of noticeable new method, for being used after activated carbon supported phosphoric acid
To adsorb NH3The research of alkaline gas is waited to have not been reported.Aluminium triphosphate, can because having characteristic that is pelletized, being insoluble in water
It is used for the absorption of amine gas, but its price is costly.Activated carbon is a kind of widely used adsorbent, because it is with larger
Specific surface area, excellent pore structure, while be also excellent carrier.After activated carbon supported a certain proportion of phosphoric acid, phosphoric acid
The inner surface of activated carbon can be attached to, NH is adsorbed by chemical reaction3The inner surface of activated carbon is remained stuck to afterwards, will not generate two
Secondary pollution.And activated carbon is less expensive, and therefore, the activated carbon for loading phosphoric acid is a kind of alkaline gas with huge applications potentiality
Body adsorbent.
The content of the invention
The object of the present invention is to provide a kind of acticarbons for loading phosphoric acid, and the adsorbent is with particle or column activity
Charcoal is as medium, the ability with efficient absorption alkaline gas.
The present invention also aims to provide the preparation process of the acticarbon of above-mentioned load phosphoric acid.
As above conceive, the technical scheme is that：A kind of acticarbon for loading phosphoric acid, it is characterised in that：By
The component of following mass percent is realized：Absorbent charcoal carrier 80-99%, phosphatase 11-20%.
The preparation method of the acticarbon of above-mentioned load phosphoric acid is as follows：
1. screen activated carbon base charcoal；
2. acid solution sprays：By phosphoric acid and water mixing, then acid solution is equably sprayed on the activated carbon using flusher；
3. it dries：The activated carbon for loading phosphoric acid is dried into 1-3h；
4. it packs：The activated carbon of dried load phosphoric acid is fitted into packaging bag or packing box.
Above-mentioned activated coal-based carbon uses 4mm column-shaped active carbons.
Advantages of the present invention and effect：
1st, the present invention makes phosphoric acid equably load to the micropore surface of activated carbon by way of spray, forms compound
Sorbing material has good adsorption effect for alkaline gas such as ammonias.
2nd, the present invention is efficient and economical and practical using activated carbon as carrier and adsorbent.
3rd, present invention process is simple, efficient, workable and non-pollutant discharge, is suitble to industrialized production.
Specific embodiment
Exemplified by preparing 1kg load phosphoric acid amounts by laboratory as the 4mm column-shaped active carbons of 14-15%, work is prepared according to the following steps
Property carbon adsorbent：
(1) 4mm column-shaped active carbon base carbon is screened；
(2) acid solution sprays；
The activated carbon screened is weighed in proportion, then claims phosphoric acid and water, by phosphoric acid and water mixing, then using flusher
Acid solution is equably sprayed on the activated carbon, when sprinkling needs activated carbon of ceaselessly stirring, to achieve the purpose that uniformly to spray.
(3) stir：
Spray phosphoric acid liquid after, activated carbon surface still have acid solution not yet impregnate completely, for ensure uniformly impregnate, it is necessary to after
Continuous stirring, until the surface of activated carbon seems dry anhydrous.
(4) it is dry：
Activated carbon is placed on drying 1-3h at dry and ventilated, if the moisture added in needs to dry higher than the moisture of requirement
Fall portion of water.
(5) pack：
Whether i.e. detectable index of correlation is qualified after drying, and then the dried activated carbon of phosphoric acid that is soaked with is packed into anti-
In the packaging bag of tide effect or packing box.
Claims (3)
1. a kind of acticarbon for loading phosphoric acid, it is characterised in that：It is realized by the component of following mass percent：Activated carbon
Carrier 80-99%, phosphatase 11-20%.
2. a kind of preparation method of the acticarbon of load phosphoric acid according to claim 1, it is characterised in that：Including
Following steps：
1. screen activated carbon base charcoal；
2. acid solution sprays：By phosphoric acid and water mixing, then acid solution is equably sprayed on the activated carbon using flusher；
3. it dries：The activated carbon for loading phosphoric acid is dried into 1-3h；
4. it packs：The activated carbon of dried load phosphoric acid is fitted into packaging bag or packing box.
3. the preparation method of the acticarbon of load phosphoric acid according to claim 2, it is characterised in that：Above-mentioned activity
Charcoal base carbon uses 4mm column-shaped active carbons.
