Embodiment
As shown in Figure 1, pollution-free digestion instrument of the present utility model comprises flat based tubes group 1 and heating arrangement, jacking gear 13, gas sampling device and exhaust gas absorption device.
As depicted in figs. 1 and 2, heating arrangement comprises that aluminium sheet 10, heating rod 11 and top are provided with the tubular heat collector panel 15 of view window 16, heating rod 11 is plugged in the bottom of aluminium sheet 10, the upper surface of aluminium sheet 10 is to having the test tube bottoming hole 12 that is complementary with flat based tubes group 1, and flat based tubes group 1 is plugged in the test tube bottoming hole 12 when clearing up reaction.Tubular heat collector panel 15 encloses portion within it perpendicular to aluminium sheet 10 and with flat based tubes group 1, fixedlys connected with aluminium sheet 10 in its bottom.
As shown in Figure 1, jacking gear 13 has lifting disk 14, and lifting disk 14 is made by heat-resistant elastic material; Each test tube mouth of flat based tubes group 1 all is removably connected with the gas sampling device by resilient seal cover 2, detachably fixedlys connected with lifting disk 14 respectively in the middle part of each test tube of flat based tubes group 1.Wherein, resilient seal cover 2 is made by acid resisting material.
As shown in Figure 1, the gas sampling device is the conduit 3 with a plurality of inlet ends, the inlet end of conduit 3 is connected with resilient seal cover 2 and its outlet side feeds exhaust gas absorption device, conduit 3 is provided with valve 9 and its outlet side is connected with hydraucone 24, the number of conduit 3 inlet ends is identical with test tube number in the test tube group 1, can be set to different quantity as required.
As shown in Figure 1, exhaust gas absorption device comprises that the alkali that the water that fills water is washed bottle 4 and filled alkaline solution washs bottle 8, and alkaline solution preferably adopts NaOH solution.As shown in figures 1 and 3, the top open part that water is washed bottle 4 is provided with end cover 7, and end cover 7 is provided with air intake opening 5 and gas outlet 6.Conduit 3 is tightly connected with air intake opening 5 and wash in the bottle 4 by air intake opening 5 and hydraucone 24 feeding water its outlet side.Alkali is washed bottle 8 top open parts and is provided with end cover 22, and end cover 22 is provided with air intake opening 25 and gas outlet 21, and alkali is washed bottle and is provided with cellular material 23 in 8, and alkali is washed in alkaline solutions in the bottle 8 are immersed in cellular material 23.Gas outlet 6 is sealedly connected with conduit 20, and the other end of conduit 20 feeds the bottom that alkali is washed bottle 8 neutral and alkali solution by end cover 22 and cellular material 23.Wherein, hydraucone 24 can just be positioned at water surface top as shown in Figure 1, also can be arranged in water and wash below the water surface of bottle 4.
When using pollution-free digestion instrument of the present utility model that sample is cleared up processing, the firstth, test tube group one is installed: the lifting disk 14 of jacking gear 13 descends, test tube group 1 is dropped to the bottom that its bottom enters the test tube bottoming hole 12 on the aluminium sheet 10, sample and acidic oxidation agent are put in vitro, a plurality of resilient seal covers 2 with conduit 3 inlet ends tightly are enclosed within on a plurality of test tube mouths of test tube group 1 correspondingly then again.The second, check that conduit 3 and water are washed bottle 4, water is washed the sealing state between bottle 4 and the conduit 20.The 3rd, connect the heating rod power supply, heating rod is started working.Heating rod is with aluminium sheet 10 heating, and with heat transferred test tube group 1, the Specimen eliminating process begins aluminium sheet 10 by test tube bottoming hole 12, and this moment, valve 9 was in open state.Under low temperature relatively, regroup and be back to the test tube bottom when oxygenant in the test tube group 1 decomposes the nitrogen oxygen thing gas that produces and rises to the test tube mouth and participate in clearing up reaction with water vapor.Clear up in the course of reaction and valve 9 can be adjusted to semi-closed state, at this moment the gas that produces in the test tube group 1 can not enter water by conduit 3 unobstructedly and wash bottle 4, thereby makes the pressure microlitre in the test tube group 1, quickens the speed of clearing up of sample.Harmful gas such as issuable excessive nitrogen oxygen thing enters water by conduit 3, hydraucone 24 and washs bottle 4 in the digestion process, absorbs a part by the water reaction, mainly is the ease of solubility harmful gas; Then harmful gas enters alkali by conduit 20 and washs alkaline solution bottom in the bottle 8, is thoroughly absorbed by alkaline solution.When harmful gas rises by the cellular spaces bending in the cellular material 23 from alkaline solution bottom, compare its rising path and obtained prolongation, make alkaline solution more abundant to the absorption of harmful gas, complete with not establishing cellular material 23.
At last, being arranged in water at hydraucone 24 washs under the situation below bottle 4 the water surface, clear up and answer valve-off 9 after reaction finishes, after descending with the temperature that prevents test tube group 1 within it portion form negative pressure and enter to cause violent expanding with heat and contract with cold to damage test tube group 1 or conduit 3 the liquid suck-back that water is washed in the bottle 4.Because can be in environment discharge of noxious gases, so this device can use in any environment and exhaust equipments such as fuming cupboard need not supportingly be set.
Certainly, the utility model includes but not limited to present embodiment, as reaction vessel, can be set to flat based tubes, also can be set to common lower arcuate surface test tube, can also be arranged to other containers such as flask; Water also can be set to be washed bottle and alkali only is set washs bottle; Above-mentioned conversion all drops within the protection domain of the present utility model.
