The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

See also Fig. 1, the device 10 of the ceramic honey comb supported catalyst that provides for the utility model embodiment.The device 10 of this ceramic honey comb supported catalyst comprises steeper 12, demarcates the calibration device 14 and the dividing plate 16 of steeping liq volume.Dividing plate 16 is arranged in the steeper 12, is used to place ceramic honey comb 15, and dividing plate 16 can allow liquid see through with dipping ceramic honey comb 15.Calibration device 14 is connected with steeper 12 with to steeper 12 topping ups.

The diapire of steeper 12 has stood vertically a plurality of legs 17, with supporting clapboard 16.Can place a plurality of ceramic honey combs 15 simultaneously on the dividing plate 16, steeper 12 and dividing plate 16 sizes can be set as required, placing the ceramic honey comb 15 of requirement, thereby can flood the ceramic honey comb 15 on the dividing plate 16 once, shorten dipping total time when reducing human cost.In other embodiments, but dividing plate 16 horizontal fixed are on the sidewall of steeper 12, for example be convexly equipped with a circle bulge loop in side wall inner surfaces, then dividing plate 16 is placed on the bulge loop, get final product stationary barrier 16, be understandable that dividing plate 16 also can be fixed on the sidewall of container 12 as the mode that fastens by other mechanical engagement.

Be carved with scale on the sidewall of calibration device 14, this scale can be a graduation mark of constant volume or the scale of evenly spaced indication volume.The calibration device 14 of present embodiment adopts a constant volume graduation mark 140, and this constant volume graduation mark 140 is demarcated the volume of required steeping liq.Be provided with an overflow lip 142 in the position of sustained height with constant volume graduation mark 140 in other words at same horizontal line on the sidewall of calibration device 14, overflow lip 142 is provided with a flow spill valve 143.When valve 143 is opened, liquid in charging into calibration device 14 reaches constant volume graduation mark 140, be liquid capacity when reaching predetermined, even continue liquid is charged into calibration device 14, excess liquid also can be overflowed and kept the liquid volume in the calibration device 14 constant by overflow lip 142.Valve 143 also can be closed when calibration device 14 topping ups, and when the liquid in charging into calibration device 14 surpassed constant volume graduation mark 140, Open valve 143 again, overflowing excess liquid, and keeps the liquid of demarcating volume.

Be connected by a pipeline 144 between calibration device 14 and the steeper 12, as interface channel therebetween, pipeline 144 is provided with one and is communicated with valve 145.As shown in Figure 1, the bottom of calibration device 14 etc. is higher than or a little more than dividing plate 16, this can be by being constructed to pipeline 144 shape of inclination, promptly extend downwards by the bottom of calibration device 14, make the inner port of pipeline 144 be higher than pipeline 144 outer vents in calibration device 14 bottoms, make the liquid in the calibration device 14 can utilize the pressure differential of this difference in height formation to flow into preferably in the steeper 12, and fully soak into the ceramic honey comb 15 that places on the dividing plate 16.In actual applications, calibration device 14 can be to be communicated with the all-in-one-piece structure with steeper 12, and perhaps pipeline 144 is fixed on calibration device 14 or the steeper 12, during use pipeline 144 is inserted calibration device 14 or steeper 12, and they are communicated with.

Calibration device 14 can link to each other with a liquid storage container 18, is input in the calibration device 14 by transfusion motor 19 control liquid therebetween.Certainly, also a liquid-transport pipe-line 146 can be set at the top of calibration device 14, by its directly import the deposit or the good steeping liq of provisional configuration.As shown in Figure 1, present embodiment adopts above-mentioned two kinds of infusion models simultaneously, and wherein liquid-transport pipe-line 146 can be standby.Motor 19 comprises a pump, during topping up by pumping action with in the liquid input calibration device 14, when liquid meets or exceeds constant volume graduation mark 140, promptly stop motor 19 operation, for example can pump be quit work automatically by a relay control.

See also Fig. 2, be one of dividing plate 16 exemplary structure.Figure median septum 16 comprises a substrate 162, offers the pore 164 that allows liquid permeate on it.The substrate 162 of dividing plate 16 is the glass or the plastics of compatible with steeping liq (promptly not reacting or phased soln with steeping liq), for example, when steeping liq tool alkalescence, be fit to adopt the dividing plate of plastic material, when the steeping liq tool is acid, be fit to adopt the dividing plate of glass material.Pore 164 is uniformly distributed on the whole dividing plate 16, thick about 5 millimeters of dividing plate, the micron order hole of pore 164 for allowing liquid permeate.Owing to offer pore 164 on the dividing plate 16, can utilize capillarity, help overflowing more uniformly and stably steeping liq, and, because the adsorption rate of ceramic honey comb 15 is very fast, by the buffering of pore 164, can alleviate the competition effect of ceramic material to steeping liq.In addition, the two-phase interface contact angle that steeping liq and pore material can be set is less than 90 °, and then capillarity can take place automatically.

In actual dipping process, dividing plate is horizontal positioned, at first opens motor 19, slowly open and be communicated with valve 145, control liquid can be full of the vacancy below the dividing plate 16, after close and be communicated with valve 145, disable motor 19 then obtains topping up state shown in Figure 3, for the back liquid infiltration is got ready.

Open motor 19, closing outflow valve door 143 and connection valve 145 flow in the calibration device 14 maceration extract in the reservoir 18.When liquid level is elevated in the volume calibration device corresponding scale, promptly during constant volume graduation mark 140, open flow spill valve 143, gather excess liquid for recycling by overflow lip 142, then realize topping up state shown in Figure 4 this moment.

Then, open connection valve 145, the liquid in the calibration device 14 of leaving slowly flows in the steeper 12.Liquid can see through the pore 164 of dividing plate 16 to vertical spread, and is finally adsorbed by ceramic honey comb 15.When waiting to flow to liquid levels in the steeper 12 and being lower than dividing plate 16, can close and be communicated with valve 145, transfer ceramic is to next process.Like this then realize the dipping of ceramic honey comb 15, this also can be regarded as a kind of method of operating of immersion system 10.

The device 10 of the ceramic honey comb supported catalyst that the foregoing description provides is provided with the dividing plate 16 that is used to place ceramic honey comb 15 in steeper 12, can be by setting the size of dividing plate 16, so that place requirement ceramic honey comb 15, liquid can see through dividing plate 16 during dipping, make that the ceramic honey comb 15 on the dividing plate can be simultaneously impregnated, realize liquid infiltration effect uniformity, so the application for the ceramic honey comb 15 of back provides reliable and stable contrast test basis.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
