Embodiment
Activated carbon is that one kind has special microstructure, and micropore is flourishing, the stronger charcoal of adsorption capacity.But activated carbon
Containing ash content, it is the inorganic part of activated carbon, easily causes secondary pollution, and the use of activated carbon also has necessarily
Limitation, it is easily saturated, usage time is shorter, it is necessary to regularly replace, and its adsorption effect to microorganisms such as bacteriums is very poor；Due to
The consideration of cost, for example in water treatment field, because active charcoal preparing process is different, and water quality is different so that it is in water
The treatment effect of pollutant differs greatly, more important is, although conventional activated carbon can adsorbing contaminant, for different
For treating decolouring product, it has different demands to adsorption capacity, moreover, conventional charcoal absorption speed is limited, for
For the rate of adsorption or percent of decolourization have the product of high requirement, it is far not by far up to the mark.
Shown in reference picture 1, a kind of compound activated carbon decolorizing material disclosed in the utility model embodiment is by positioned at table
The active carbon layer 1 of layer, the mixed layer mixed by atlapulgite layer 2 and diatomite layer 3 positioned at nexine form, and are formed sandwich
Structure, the activated carbon decolorizing material are in spheroid, cube or other any appropriate gengons.Wherein, the active carbon layer 1, activity
Albic horizon 2 and diatomite layer 3 are made up of activated carbon granule, atlapulgite particle and diatomite particle (or powder) respectively, described
Atlapulgite layer 2 and diatomite layer 3 are respectively positioned on nexine and are sequentially arranged at intervals, between the activated carbon 1 and diatomite layer 3, institute
State between active carbon layer 1 and atlapulgite layer 2, be bonded between the atlapulgite layer 2 and diatomite layer 3 by polymeric adsorbent 4.
Layered design is not being influenceed outside each material performance itself, can conveniently be stored and transport.The material is when meeting water, you can is mutually dissolved
Mixing.When not soluble in water, the respective material property of meeting will not be broken, corresponding substance reaction, convenient storage will not be produced.
Wherein, the active carbon layer 1 is located at outer layer, by cocoanut active charcoal particle and wooden pure plant type activated carbon
Uniformly mixing composition, the thickness of the active carbon layer 1 are higher than the height of the atlapulgite layer 2 and the thickness of diatomite layer 3 to grain.
Specifically, the compound absorbent charcoal material preferably has following weight proportion；Cocoanut active charcoal 40%~55%, wooden activity
Charcoal 20%~30%, resin 8%~14%, atlapulgite 4%~8%%, diatomite 4%~6%.
Refer again to shown in Fig. 1, can be left and right directions between the atlapulgite layer 2 and diatomite layer 3 of nexine, upper and lower
Direction or criss-cross arrangement, keep can directly contacting between active carbon layer 1, atlapulgite layer 2 and the three of diatomite layer 3
State.
Further, in said one embodiment, layer of non-woven fabric material has been wrapped on the top layer of the decoloring material
Material, can be fabricated to different size different shape, be also convenient for packing, and nonwoven cloth material permeability itself is good, and have necessarily
Strainability, large granular impurity can be filtered out.The decoloring material is lived by non-woven wraps, so, this there can be non-woven fabrics
Compound activated carbon decolorizing material be placed in technique or the devices such as monosodium glutamate is decolourized, saccharin is decolourized, white sugar decolourizes, wine brewing is decolourized,
It is also convenient for storing and transports.
Between the active carbon layer 1 of the present utility model and diatomite layer 3, the active carbon layer 1 and atlapulgite layer 2 it
Between, be bonded by polymeric adsorbent 4 between the atlapulgite layer 2 and diatomite layer 3.Wherein, resin has porous three-dimensional in itself
Structure, itself has certain adhesive, can connect each material adsorption layer, meanwhile, resin is by it and adsorbed molecule
Van der Waals force between (adsorbate), physical absorption is carried out by its huge ratio surface to work, polymeric adsorbent is in itself not
Water, acid, alkali and organic solvent are dissolved in, is not also chemically reacted with them.In active carbon layer, diatomite layer, atlapulgite layer
Between add appropriate polymeric adsorbent, on the one hand, so that each material adsorption layer is in the case where influenceing the change of structure of matter itself,
Cooperate, during use, by the pore structure inside each material adsorption layer, interpenetrate, enhancing absorption and decolorizing effect.
On the other hand, polymeric adsorbent is added in activated carbon, enable to caused by dust it is few, caused by pollute it is also few, it is prior
It is so that manufactured decolorising agent light transmittance is fabulous.In addition, inner material layer is preferably to external diffusion, the absorption for convenience
Its thickness gradually increases resin from outside to inside, also just says that centre position polymeric adsorbent thickness is maximum.
Specifically, atlapulgite relative density 2.3~2.5, swelling is minimum in water and oil.Therefore, its is particularly suitable
Decolorising agent and sugaring field in greases such as edible oils, have good decolorizing effect, can be with conditions of percent of decolourization is ensured
It is undesirable in terms of water source and grease type decolouring to make up single activated carbon.Meanwhile in use, atlapulgite particle
It gradually can slowly be merged with active carbon particle, strengthen antioxidant effect, reach the purpose of fast purification.Diatomite is by silicon
A kind of pure natural siliceous organism sedimentary rock that algae is formed.Microcellular structure and particle distribution characteristics with uniqueness, can form infiltration
Property filter layer, filter out tiny suspended solid, filtrate is reached high cleaning, be particularly good at absorption retention solution in suspension
Particulate, solution plus diatomite filtering can be obtained into limpid filtrate.Activated carbon and atlapulgite are using internal molecular structure
Reach the purpose of absorption, and diatomite is organic natural prodcuts, mainly plays a part of drainage, it has abundant absorption
Hole, and be not easy to be dissolved by soda acid, each product has oneself unique absorption aperture, and combination can be interpenetrated when being dissolved in water, is not dissolved in
During water, the respective material property of meeting will not be broken, diatomite, resin, activated carbon and atlapulgite are used in combination, and adsorption capacity is more
By force, it can substantially accelerate the rate of filtration and improve filter effect, have also been enlarged the use range and application field of activated carbon.
