Description
Technical field
The utility model belongs to gas sampling technologies field, particularly a kind of sampling apparatus that can gather the gas that antiquated books discharge.
Background technology
At present, preserve the antiquated books of some preciousnesses in archives and library, these antiquated books reflect the situation such as politics, economy, military affairs, culture of different period of history, have great historiography researching value and value for preservation.But when entering into these archives or library, we often smell in storehouse, shop dense or light smell, even denseer taste can be smelt near these antiquated books.In light of this situation, we propose to carry out collections detection to the gas in these antiquated books, analyze its composition, study the impact of these gases on antiquated books and collection environment.
Before analyzing these gases, we need to collect the gas in antiquated books.By consulting literatures, find that common gas collection method has direct acquisition method, liquid acquisition method, solid acquisition method, harvester has makes container inner pressure reduce by vacuumizing, thus ambient atmos is entered, but, in antiquated books, gas is micro-, do not reached the object of collecting gas in antiquated books, and this apparatus structure is complicated by this device.For this reason, we devise the device of gas in this kind of antiquated books of a kind of special collection.
Summary of the invention
In order to overcome the problem of existing antiquated books release gas collecting difficulty, it is convenient and the antiquated books of direct sampling method and solid sampling method compatibility can be discharged the sampling apparatus of gas that the utility model provides a kind of features simple structure, sampling.
The technical scheme that the utility model adopts is: this device comprises airtight container, the body of airtight container is provided with obturating plug, obturating plug is processed with through hole, through hole is provided with rubber plug and the porch of through hole is provided with filter net cloth, rubber plug and obturating plug are tightly connected, and airtight container inner chamber is provided with adsorption stuffing.
Above-mentioned adsorption stuffing accounts for 1/30 ~ 1/10 of airtight container volume.
Above-mentioned adsorption stuffing is activated charcoal, molecular sieve or polymeric adsorbent, and activated charcoal is powdery or bar-shaped or graininess.
The sampling apparatus of the antiquated books release gas that the utility model provides, it is by arranging obturating plug on airtight container, rubber plug and be filled with adsorption stuffing at inner chamber, the gas that antiquated books are discharged seals in airtight container, the adsorption stuffing of filling is utilized to adsorb gas, realize solid sampling, or directly gathered by rubber plug, by compatible for the device of solid sampling and gas Direct Sampling, to adapt to different testing tools and accessory, in addition, the utility model structure is simple, easy to operate, extract rubber plug and can increase and decrease activated charcoal, and this sampling apparatus to the antiquated books of preciousness without destruction, good airproof performance, the impact of ambient atmos can be prevented, repeatedly can extract sampling simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of sampling apparatus in embodiment 1.
Embodiment
Now by reference to the accompanying drawings the technical solution of the utility model is further described, but the utility model is not limited only to following enforcement situation.
Embodiment 1
As shown in Figure 1, the sampling apparatus of the antiquated books release gas of the present embodiment is made up of airtight container 1, rubber plug 5, O-ring seal and adsorption stuffing 2.
A polybag sealed selected by the airtight container 1 of the present embodiment, it is 75cm that this polybag adopts long, wide is 60cm, thickness is the transparent vacuum packaging bag of 32, obturating plug 3 is fixed with hot pressing mode by bag, through hole is had at the center of obturating plug 3, through hole is provided with rubber plug 5, ensure that rubber plug 5 and obturating plug 3 are tightly connected, at the inlet end of obturating plug 3 through hole, a filter net cloth 4 is installed, when can prevent gas sample, active carbon powder results in blockage, active carbon powder is filled with as adsorption stuffing 2 in the inside of polybag, be filled in sealing bag, in order to ensure that sampled result is accurate, ensure that the volume of active carbon powder accounts for 1/20 of polybag volume.
During use, antiquated books are first encapsulated in polybag, and then polybag is all sealed, with vacuum packing machine, this closure polybag is vacuumized, be placed on lower 3 months of the physical environment even longer time after sealing, the gas existed in the antiquated books in bag can be as much as possiblely full of in whole bag.If desired gaseous sample, can insert from vulcanized rubber plug 5 with gas sampling pin, extracting gases, if desired the solid acquisition method of gas is realized, can extract rubber plug 5, be taken out by active carbon powder by through hole, solid sampling method conveniently detects active carbon powder, installing rubber plug 5 afterwards can repeated sampling, realizes the gas collecting of different time sections.
Embodiment 2
The airtight container 1 of the present embodiment selects one with the sealed glass jars of top cover, offering mounting hole at vial top is arranged in mounting hole by obturating plug 3, correspondingly on the through hole of obturating plug 3, rubber plug 5 is installed, active carbon stick is placed at vial inner chamber, active carbon stick volume accounts for 1/10 of vial volume, other parts and annexation identical with embodiment 1.
Embodiment 3
A vial sealed selected by the airtight container 1 of the present embodiment, vial offers mounting hole to be arranged in mounting hole by obturating plug 3, correspondingly on the through hole of obturating plug 3, rubber plug 5 is installed, activated carbon granule is placed at vial inner chamber, activated carbon granule volume accounts for 1/30 of vial volume, other parts and annexation identical with embodiment 1.
Adsorption stuffing 2 in above-described embodiment can also be replaced with the sorbing material such as molecular sieve, polymeric adsorbent, also can be selected according to actual service condition by technician.
