Summary of the invention
The invention provides a kind of multi-functional Immesion active carbon and preparation method thereof, be mainly used in containing H
2S, SO
2, NO
2, O
3, VOCs such as organic amine and benzene carries out comprehensive purifying and protection.
Immesion active carbon of the present invention is carrier with the active carbon, with Cu, K, Na, I, OH base is active constituent, and the percentage that each component accounts for the Immesion active carbon gross weight is: Cu 2.5～12%, K 2～10%, Na 0.5～9%, I1～8%, with stoichiometry OH base 2～13%; Immesion active carbon Cu component is dissolved in 20～30% ammoniacal liquor, all the other component water dissolvings, under 50～80 ℃ temperature, be hybridly prepared into maceration extract, maceration extract is determined the dipping solution volume according to the water capacity of active carbon, method with single-steeping or step impregnation under 50～90 ℃ temperature is impregnated on the active carbon equably, places 0.5～8hr then in air; Above impregnated carbon material is placed drying oven or fluid bed, and under the condition of 130～180 ℃ temperature and control oxygen atmosphere, substep is dry, activation 2～6hr, makes Immesion active carbon.
Cu in the Immesion active carbon of the present invention source is with metal copper scale or metal copper wire ammonification water, CO
2Be dissolved as copper-ammonia solution, also available basic copper carbonate reagent adds water, ammonium carbonate and ammoniacal liquor and is mixed with copper-ammonia solution; K derives from potassium hydroxide, KI or Potassiumiodate; Na derives from NaOH or sodium carbonate; I derives from solid iodine reagent, KI or Potassiumiodate; The OH base derives from potassium hydroxide or NaOH.
Preparation method of the present invention comprises the dipping of the preparation of maceration extract and active carbon and drying, three steps of activation:
1, the Cu in the active component adds ammoniacal liquor and logical CO with copper scale or copper wire
2Dissolving is mixed with copper-ammonia solution, perhaps basic carbonate DDTC and ammonium carbonate water and ammoniacal liquor is mixed with copper-ammonia solution, and all the other component waters dissolve, and hybrid modulation becomes maceration extract under 50～80 ℃ temperature;
2, with the dipping solution volume of above-mentioned maceration extract according to the definite adding of active carbon water capacity, the method with single-steeping or step impregnation under 50～90 ℃ temperature is impregnated on the active carbon, places 0.5～8hr then in air;
3, above-mentioned impregnated carbon material places drying oven or fluid bed, and under the condition of 130～180 ℃ temperature and control oxygen atmosphere, substep is dry, activation 2～6hr.
Immesion active carbon of the present invention, key technology is: the ratio of 1. controlling each component in the maceration extract, otherwise the combination property of making Immesion active carbon is relatively poor: 2. the preparation of maceration extract must be according to the program of setting, otherwise the active component that has in the product of Immesion active carbon does not reach the content requirement of expection, and product quality is with inhomogeneous; 3. control the atmosphere of the temperature oxygen of drying, activation according to segmented program, because in the process of drying, activation, the beginning impregnated carbon is absorbed heat in large quantities, dip composition decomposes then, some product volatilization, sometimes also be accompanied by the heat release of charcoal layer particle surface, adopt common drying means easily to cause the charcoal layer to glow, catch fire.And the present invention adopts drying, the activation method of segmented program control temperature, and control contacts the amount of oxygen in the atmosphere with impregnated carbon, can effectively avoid glowing of charcoal layer in the activation process.Adopt above preparation technology, thereby guaranteed the safety of impregnated carbon production process, make the steady quality of product.
The carrier active carbon that the present invention uses is: granule strength 75～95%, loading density 420～490g/L, water capacity 70～100%, to carbon tetrachloride adsorption rate 60～90%, granularity is φ 0.7～2mm, be shaped as column, spherical activated charcoal or broken shaped activated carbon, it is 71～90% that absorbent charcoal carrier accounts for the Immesion active carbon weight ratio.
The active constituent of Immesion active carbon load of the present invention is in the Immesion active carbon gross weight, and total content is not more than 29%.
Immesion active carbon advantage of the present invention is to H
2The absorption property of S and VOCs is best, and good to the comprehensive absorption property of multiple pernicious gas, impregnated carbon does not contain harmful composition.Be applicable under the normal temperature and pressure as the air purifier adsorbent, poisonous, pernicious gas in various operating rooms, insulating space, the closed in space are purified remove.
