The specific embodiment
Embodiment 1
According to Fig. 1 and Fig. 2 embodiments of the present invention 1 are described.
As shown in Figure 1, the filter 10 of present embodiment is the utensil of granular filter base-material 13 (aftermentioned) of packing in the metal filter housing 15 that roughly is cuboid of the about 30cm of longitudinal size, the about 30cm of lateral dimension, thick about 1.5cm.
In detail, filter housing 15 is to dispose the latticed porous plate 12 that formed a plurality of square passage 12A and constitute on two opening surfaces of flat framework 11.Between the porous plate 12 granular filter base-material 13 is being housed up and down, the size of mesh opening of this porous plate 12 is set to the average grain diameter less than granular filter base-material 13, thereby prevents that filter base-material 13 from spilling (with reference to Fig. 2).
At least part surface applied by apatite, further adhere to Nano silver grain on granular porous ceramics and/or the porous carbon materials and form granular filter base-material 13.
As the material of granular porous ceramics, the material of ceramic slag or the pottery sheet that the pottery fragmentation that is fired into is obtained, cordierite, mullite series material, silicon-carbide series etc. all can use.And among these materials, effectively be used to the viewpoint that reduces cost, the pottery sheet (calling " pottery sheet " in the following text) that preferably uses the broken pottery that bakes to obtain from what promote again articles for use.
Pottery sheet in the porous ceramics can be made graininess to the pottery crushing and classification that is fired into pulverizer, and the material beyond the pottery sheet can compression moulding be that bead is fired and made graininess.In the present invention, also can in the pottery sheet of meticulous fragmentation, add cement material and water, become graininess with comprehensive mixer etc. then.The cement material that is added in the pottery sheet as meticulous fragmentation can be a portland cement etc.
As porous carbon materials, for example can be intermediate cutting timber is become granular wood chip and with this as raw-material active carbon or charcoal etc.Active carbon can be made by steaming the burning wood chip.In the above-mentioned material, from the high viewpoint of adsorptivities such as stink, preferably active carbon.
In order on the surface of porous ceramics and porous carbon materials (following both are referred to as porous material), to apply apatite, can adopt following known method: make the porous material rotation also the superincumbent method of slurry drops that contains the calcium phosphate series material with comprehensive mixer, porous material is immersed in the method in the slurries that contain the calcium phosphate series material, and porous material is separated out the method etc. of apatite crystal 37 ℃ plan like the dipping stipulated time in the body fluid.
Employed series of calcium phosphate material can obtain with following known method in above-mentioned method, that is: make calcium hydroxide and phosphatase reaction method, make Ca
8H

2The method of reaction etc.Necessary words, in these reactions, can use the dispersant of polycarboxylic acids series, just can obtain the slurries of calcium phosphate series material with adding distilled water in the resulting calcium phosphate material of the method for above-mentioned example and the flocculating agent etc. that adds polycarboxylic acids series as required again.
After the surface applied apatite of porous material, also can improve the stability of adhering to of apatite via following operation.
For example, for using CaHPO
42H
2O and Ga
3(PO
4)
2React resulting calcium phosphate slurries, can be placed on the porous material after the apatite coating in 80 ℃ to 100 ℃ the saturated steam maintenance 24 hours, apatite is stable to be adhered to and make.
For using Ca

2(PO
4)
65H
2O and CaO or Ca (OH)
2React resulting calcium phosphate slurries, also can drop into the porous material after the apatite coating in the pressure vessel, carry out 2 hours to 6 hours reaction under 180 ℃ to 250 ℃, 1MPa pressure, apatite is stable to be adhered to and make.
If use porous carbon materials as porous material, also can apply the porous material behind the apatite and put into and squeeze into steam treated in the converter following of 700 ℃ to 800 ℃ condition, and being stablized, adheres in apatite.
In addition, also can fire 2 hours to 6 hours at the porous material behind following coating of 900 ℃ to 1600 ℃ the temperature apatite, apatite is stable to be adhered to and make.
Then, further adhere to Nano silver grain on the surface of the porous material that has applied apatite, like this, Nano silver grain just can play a role effectively.Specifically, be that a porous material that has applied apatite is immersed in the dilution of general commercially available Nano silver grain, just obtain granular filter base-material 13 after making its drying.
In the present invention and since granular filter base-material 13 be contained in can ventilate or water through filter housing 15 in, so along with filter base-material 13 particle diameters diminish, voidage reduction.If voidage is too low, air or water just be difficult to by, cause obstruction easily.
On the contrary, along with particle diameter becomes big, the whole surface area of filter base-material 13 diminishes, and adsorption capacity, decomposition and the antibacterial action of absorption odor pollutant etc. will reduce.Ventilate (water flowing) property and adsorption capacity are considered in balance, and the average grain diameter of granular filter base-material 13 is 2mm to 10mm preferably.
When making filter 10 of the present invention in the filter housing 15 by this granular filter base-material 13 is encased in, both can be used alone above-mentioned granular filter base-material 13, also can use two or more granular filter base-materials 13 simultaneously.
According to above-mentioned, because the filter 10 of present embodiment is a kind of filter that forms in the metal filter housing 15 that can ventilate that filter base-material 13 is encased in, so the ceramic component that is not rapid wear is exposed to the structure that the outside is come, the parts that directly bear external force are metal filter housings 15, therefore, installation exercise or be difficult to damage when repairing.Though also exist filter base-material 13 to collide mutually and situation about damaging in filter housing 15 internal causes, just filter base-material 13 particle diameters diminish, and can't influence the intensity of filter itself, so can not break down.
And employed in the present embodiment filter base-material 13 is coated with apatite on its surperficial at least a portion, so pernicious gas, odor pollutant and bacterium etc. that can absorbing ammonia and so on.And, be coated with on the porous material of apatite and further adhered to Nano silver grain, so, have the effect and the antibacterial action that decompose adsorbed odor pollutant, therefore, filter base-material 13 is suitable for use as the base-material of filter 10 very much.
Under the situation of the size that must meet air-conditioning etc. with the filter 10 of all size, also do to such an extent that conform to its size filter housing 15, and because filter base-material 13 is granular, so can increase and decrease the charge weight of filter base-material 13 at an easy rate according to filter shell 15 sizes.That is,,, therefore can not increase cost so can easily produce the filter 10 of all size owing to needn't come molding filter device base-material 13 according to the size of filter 10.
In addition, because filter base-material 13 is granular, so in order to adjust ventilation (water flowing) amount, can change the charge weight or the particle diameter of filter base-material 13 freely, when waiting the reductions such as adsorption capacity that make 10 pairs of pernicious gases of filter because of long-term use, both can only take out filter base-material 13 and change, and also can take out filter base-material 13 and utilize again after cleaning.
