Description
Technical field
The invention belongs to impregnated carbon technical field, have for a kind of efficient impregnated carbon that can be used for carrying out multiple indusrial toxic harmful gas under complex environment effectively purification.
Background technology
After active carbon and impregnated carbon thereof are Two World Wars, grow up gradually and the chemical defence be widely used equipment (comprising individual combat protective gear and cluster protective equipment) core filter malicious material.Along with the development of chemical warfare, various countries are more and more, more and more darker to the research of warfare agent, the development of impregnated carbon is also with rapid changepl. never-ending changes and improvements, from initial activity charcoal, one pack system load (A type activated-carbon catalyst) to multicomponent load (AS type, ASC type, ASC-T type and ASZM-T type activated-carbon catalyst etc.), develop into gradually can effectively protect multiple toxic agent simultaneously from the initial protection for single toxic agent.
In recent years; the environmental pollution caused due to the natural calamities such as paroxysmal industrial chemical production accident, frequently earthquake and industrial economy fast development and the continuous deterioration of human settlement; great threat is caused to the personal safety of its people; therefore along with the continuous enhancing of national sense of self-protection, the protection requirements under non-war environment is more and more outstanding.Although the kind of protective materials in the market---impregnated carbon is multifarious, there are anti-NH3 impregnated carbon, H2S, SO2 protection impregnated carbon, NOx protective materials and HCN, CHCL protective materials etc., but from protection object, these impregnated carbon meet the protection to a certain or a certain class poisonous and harmful substance only at present, under the type having little time to make toxic and harmful clear and toxic and harmful kind complicated situation, above-mentioned impregnated carbon just can not meet protection requirements.
Summary of the invention
The object of the present invention is to provide and a kind ofly can be used for efficient impregnated carbon of multiple indusrial toxic harmful gas being carried out under complex environment to effectively purification and preparation method thereof, this impregnated carbon can meet HCN, NH simultaneously

The present invention adopts following technical scheme to realize:
The efficient impregnated carbon of a kind of industrial gas defence, adopt coconut husk crushing activated carbon as carrier framework material, on it, load has 13% ~ 20%(weight) Cu, 2% ~ 6%(weight) Mo, 0.1% ~ 3%(weight) Zn, 0% ~ 7%(weight) CO
3 2-, 5% ~ 10%(weight) SO
4 2-.Wherein, in the weight of carrier material active carbon for 100%, such as active carbon 100g, needs copper 13 ~ 20g, molybdenum 2 ~ 6g, zinc 0.1 ~ 3g, carbanion 0 ~ 7g, sulfate ion 5 ~ 10g.
Wherein Cu derives from basic copper carbonate, and Mo derives from ammonium molybdate, and Zn derives from basic zinc carbonate, and source of carbonate ions is in ammonium carbonate, potash, and sulfate ion derives from ammonium sulfate.
The preparation method of above-mentioned efficient impregnated carbon is as follows:
(1) mixed solution configuration: the impregnating agent containing above-mentioned active component is joined the ammoniacal liquor calculated and distilled water (wherein, the ratio of ammoniacal liquor and distilled water is 20:1) mixed solvent in (adopt equivalent impregnation method, the water capacity that consumption those skilled in the art press absorbent charcoal carrier calculates), heating is also constantly stirred, impregnating agent is fully dissolved, solution temperature to be mixed reaches 60-80 DEG C, stops heating;
(2) flood: the above-mentioned mixed solution configured is joined in the impregnation box filling a certain amount of coconut husk crushing activated carbon, stirs rapidly, until solution is fully absorbed, load more than sealing and standing 1-2h in sealing bag;
(3) activate: joined by mixed material in the air draught of heat and carry out calcining dry (namely flow bed activation method), when gas flow temperature reaches 140 DEG C, start timing, continue reaction 30 ~ 40min, temperature controls between 140 ~ 190 DEG C.Activation is critical process prepared by impregnated carbon, and the control of activation temperature and time is particularly important, and temperature is too high, easily causes hot-spot and causes layer of charcoal to be caught fire; Temperature is too low or soak time is short, and activation process can be caused insufficient, and the active component in carrier can not be converted into the composition with catalytic degradation noxious material effectively.
The present invention will comprise Cu, Mo, Zn, CO
3 2-, SO
4 2-be impregnated on carrier framework material Deng in interior blending constituent, be converted into the active principle with reactivity or catalytic action by heat-activated, wherein have acid poisonous and harmful substance (as: HCN, H containing Cu impregnating agent
