Description
Technical field
The method that the present invention relates to the medicinal waste active carbon of a kind of microwave heating activation regeneration paracetamol, belongs to resource circulation utilization technical field.
Background technology
Paracetamol is one of at present main antalgesic, to alimentary canal nonirritant, also can not cause blood coagulation disorders, becomes the main development kind of analgesic-antipyretic.Paracetamol can produce a large amount of impurity in preparation process, produces huge pollution for water resource, so for the most important thing that is treated as of paracetamol sewage.Active carbon has mainly played impurity and the effect except look of removing in paracetamol production process.In paracetamol production process, active carbon powder drops into from reactor top, with the abundant hybrid reaction of paracetamol waste water, and then by filter, waste active carbon is filtered out.Because active carbon is using adsorption capacity later obviously to decline, directly abandon or directly burn so usually not treated.Do like this and not only caused the huge wasting of resources, but also polluted environment.So become the focus of research in the present age for the activating and regenerating technology of discarded active carbon, also become the important topic of pendulum in face of numerous scientific workers.
Along with active carbon is applied widely, activating and regenerating technology more and more causes people's attention.And the feature such as the selective heating of microwave heating technique, firing rate be fast, pollution-free has increased the efficiency of experiment greatly, shorten the reaction time of experiment, greatly reduce energy consumption.
The present invention, using the paracetamol medicinal carbon discarded as raw material, by the mode of heating using microwave, carries out activating and regenerating to discarded active carbon under the condition that does not pass into any protective gas and activated gas.Because promptly making the moisture of active carbon inside, heating using microwave becomes steam, the steam producing contributes to the dredging in active carbon duct and reproduces very much, so recovered rapidly activated carbon adsorptive capacity, accomplish recycling of discarded object, turned waste into wealth, greatly reduced energy resource consumption, realize recycling of discarded object, greatly improve the comprehensive utilization ratio of resource, also reduced the pressure of environmental pollution aspect, produced significant economy and ecological benefits.
In the patent that applicant is 200510019670.9 in the patent No., a kind of " microwave plasma regeneration method of active carbon " disclosed, this method is to utilize microwave-excitation irony discharge body to produce plasma, then plasma is oxidized the organic matter being adsorbed on damp state active carbon, electrolysis degradation of organic substances in simultaneously producing between irony discharge body, active carbon and organic matter, after peroxidating and degraded, make to obtain regeneration activity recovery with the industrial activited carbon of crossing.Foregoing invention is compared with the present invention, the one, raw material of the present invention is powder-material, if add irony discharge body and obstructed protective gas in activation process, because its local electronic temperature is at least 10000 DEG C, be that this discarded active carbon of 200 objects is to be very easy to scaling loss for granularity; The 2nd, foregoing invention has been added irony discharge body, easily form iron ion, and active carbon has the function of adsorbing metal ions under the environment of high temperature humidity.For being used for specially the active carbon of paracetamol production process, can produce secondary pollution to this medicine if be mingled with some metal ions, patient is produced to immeasurable security risk.
In the patent that applicant is 201110343234.2 in the patent No., a kind of " method of microwave-assisted regeneration active carbon " disclosed, this method is that the waste active carbon to produce in sugared production process is raw material, utilize the sodium tartrate aqueous solution or sodium citrate aqueous solution that the organic components such as the caramel in activated carbon granule surface and macropore are leached, then add water and mix and add activating agent absolute ethyl alcohol, Sodium Polyacrylate, natrium citricum or their mixture, with ammoniacal liquor, NaOH or their mixture are adjusted at system pH between 8.5～10.5, be placed in microwave irradiation device radiation treatment 10～30min, thereby realize the regeneration of active carbon.Foregoing invention is compared with the present invention: the one, and said method has been introduced the materials such as absolute ethyl alcohol, Sodium Polyacrylate, natrium citricum in activation process, not only making experimental implementation become complicated cost has increased, but also the secondary pollution that has brought regenerated carbon, and the present invention does not introduce any auxiliary reagent, cleanliness without any pollution, operates also simple completely; The 2nd, in said method, the fineness of discarded active carbon is 5 order～200 orders, and in this experiment, requirement is 200 orders, and it is very very difficult in the situation that fineness is so little, but reaching so good regeneration effect comparatively speaking; The 3rd, in the present invention, microwave activation temperature retention time needs only 8 ~ 10min, and the above-mentioned invention microwave radiation processing 10min～30min that authorized has reduced energy consumption in contrast.
Summary of the invention
For problem and the deficiency of above-mentioned prior art existence, the invention provides the method for the medicinal waste active carbon of a kind of microwave heating activation regeneration paracetamol.This activation method does not pass into protective gas, has simplified experiment flow, operates quite simply, and energy consumption is low and pollution-free, and this activating and regenerating active carbon out recovers original absorption property substantially, and its specific area reaches 1000m
2more than/g, total pore volume is 0.95 ~ 1.10ml/g, and the present invention is achieved through the following technical solutions.
