Further, described first electronic cooling dehydrater 302 can be semiconductor cooler, uses extraordinary quasiconductor material The P-N junction that material is constituted, formation thermocouple pair, generation Peltier effect (when two kinds of different metals couple together and pass to electric current, Have a joint heat absorption, another joint heat release), a kind of New Refrigerating method i.e. freezed by unidirectional current.Electronic cooling effect Producing the principle being through thermoelectricity, be the cooling piece of a monolithic, it is made up of two panels potsherd, has N-type and p-type in the middle of it Semi-conducting material (Tellurobismuthite .), this semiconductor element on circuit be with cascade connect composition.Semiconductor chilling plate Operation principle be: when one block of N-type semiconductor material and one block of P-type semiconductor material are coupled to galvanic couple pair, with copper sheet two Individual quasiconductor couples together.After connecting DC current in this circuit, just can produce the transfer of energy, electric current is by N-type element The joint flowing to p-type element absorbs heat, becomes cold end, p-type element flow to the joint release heat of N-type element, become heat End.By various radiating modes, the heat in hot junction being taken away, cold end just can keep lower temperature.The size of heat absorption and heat release is logical The size of overcurrent and the element logarithm of semi-conducting material N, P determine.By up to a hundred, galvanic couple is unified into inside cooling piece Thermoelectric pile (such as right figure), to reach to strengthen the effect of refrigeration, when heat load is zero, the strongest refrigeration can reach 80 DEG C of temperature Difference.The temperature difference amplitude of electronic cooling limits, and also further illustrates the condensation of described first step glass physical except the necessity of water.

And then, owing to there being the water removal phase of first two steps, most moisture have been removed by, so having only to The first a small amount of adsorbent 303 i.e. can reach the effect well eliminating moisture, thus is greatly saved the usage amount of adsorbent, Overcome tradition azotometer and use the defect that a large amount of adsorbent costs are high.As preferably, the adsorbent in the embodiment of the present invention can To be silica gel, activated alumina or activated carbon.

Last it should be noted that by above-mentioned one-level water removal body 310, effectively ensure through burner 200 After combustion product steam remove completely, so that moisture impact on the accuracy of nitrogen analysis is completely eliminated and permissible Direct analysis fluid sample, thus it is substantially reduced the use of adsorbent, reduce operating cost.Certainly, as stated above, herein The present invention only only includes in water trap 300 as a example by one-level water removal body 310 that the operation principle to water removal body is retouched State, during actual job, it is possible to 310, two grades of water removal bodies 320 of one-level water removal body and third class de-watering mechanism 330 are pressed Constituting water trap 300 according to above-mentioned connected mode 1-3 and carry out efficient water-removing, the present invention does not limit to, the most superfluous State.

Secondly, for reduction apparatus 400,

Described reduction apparatus 400 includes: reduction furnace 402, part flow arrangement 401, non-dispersive IR line (NDIR) sensor 403.Wherein, described part flow arrangement 401 and the direct phase of described electronic cooling (2 DEG C) dehydrater 302 in higher level's water trap 300 Even, it is connected with described reduction furnace 402 subsequently, is sensed by described NDIR between described reduction furnace 402 and described purifier 500 Device 403 is connected.
