The specific embodiment
Below in conjunction with accompanying drawing, enforcement of the present utility model is specified:
Embodiment one
According to structure shown in Figure 1, sample gas is heated to 120 ℃ by gas sampler 1 by the heater 7 of tube wall, makes moisture content in the gas phenomenon of dewfall not occur on the one hand, and protective gas sampling pipe 1 is not corroded on the other hand.Sample gas enters resampling filter heater 7 with the flow velocity of per minute 1L after by gas sampler 1 and is heated to 120 ℃, and the moisture content in the gas is further evaporated, and filters bulky grain thing in the sample gas.
The sample gas that has 120 ℃ is respectively 5um millipore filter 2 and 0.1um millipore filter 3 by filtering accuracy.Filter adopts polytetrafluoroethylmaterial material to make, and filter core adopts macromolecule PE material to make, and has high temperature resistant, corrosion resistant characteristics.Drop in 80 ℃ by the sample temperature degree behind the double-filtration, satisfy the operating temperature of air pump 4.
It is cellular that Nafion pipe 5 adopts 50 Nafion to divide the effective fluorubber of proton exchange to be fixed into, and purpose is the dry amount that adds full-page proof gas.Shell and inlet, outlet adopt stainless steel 316L fine finishining moulding, sealing and fixing.Nafion manages 5 intake sections and is operated in heated condition, is heated to 90 ℃, and exit portion is operated in the normal temperature state.Air pump 4 is managed 5 sample gas inlet with the pretreated sample gas of sampler from Nafion and is entered in the pipe.Moisture content in the sample gas transmits hydrone because Nafion pipe 5 interior Nafion divide the inside pipe wall of proton exchange pipe to deposit the moist gradient difference and begin with the pipe outer wall to the pipe outer wall.Because intake section is operated in heated condition, the transmission speed of hydrone is than very fast, but dew-point temperature is low inadequately.When the sample gas of removing part moisture content enters the latter half of Nafion pipe 5,, the moisture content of not removing in the sample gas is further got rid of because work at normal temperatures.
In Nation pipe 5, ion channel extends to outer surface by the inner surface of pipe.Hydrone at first combines with sulfonic group on the inner surface, the hydrone of the sulfonic group combination of tube wall depths less (supposing that the pressure of outer surface water vapour is lower than the pressure of inner surface water vapour), therefore hydrone there is stronger attraction, the hydrone of pipe internal surface will pass through sulfonic group very soon, arrive the outer surface of tube wall, be dispersed in the environment, realize to wet sample aerocolloidal go molten.The sweep gas (normally air) that the moisture of being discharged by Nafion pipe 5 is dried is taken system out of, and then the inside and outside barometric gradient that exists of tube wall can guarantee that molten process continues to carry out.
