Abstract
The invention relates to a sampling bottle for measuring soil release gaseous mercury. The sampling bottle comprises a bottle body and a rubber plug matched with the bottle body, wherein a sampling pipe, an air inlet pipe and an inert gas inlet pipe are arranged on the rubber plug; the sampling pipe, the air inlet pipe and the inert gas inlet pipe are respectively communicated with the interior of the bottle body and are used for connecting gas inside and outside the bottle body; and airbag is arranged at one end of the air inlet pipe inserted into the bottle body. According to the sampling bottle, when the same amount of soil sample is tested, a large amount of gas samples can be collected, and the analytic error is reduced; sampling is directly performed at the sampling pipe orifice, and gas loss is avoided; and moreover, due to the airbag, the phenomenon that the actual sample gas amount is reduced due to the reduction of air pressure in the bottle body is avoided because the outside air enters the airbag to balance the air pressure in the bottle during sampling.
Description
Technical field
The present invention relates to a kind of sampling thief, relate in particular to a kind of for measuring the sampling thief that soil discharges gaseous mercury.
Background technology
Carry out the research of soil release mercury and need carry out bottled simulation test to pedotheque, owing to there is not special sample devices, in the collecting bottle during gaseous sample, the general method that adopts syringe to pierce through the plug extracting gases, but this method of sampling has three significant disadvantages at least: the one, and the gaseous sample amount is fewer, and analytical error is big; The 2nd, syringe inwall meeting adsorption sample gas causes the loss of sample gas; The 3rd, cause bottle internal gas pressure to reduce during sampling and cause actual sample tolerance not enough.
Summary of the invention
Technical matters to be solved by this invention provides a kind of for measuring the sampling bottle that soil discharges gaseous mercury, and overcoming the available technology adopting syringe, to pierce through plug extracting gases sample size fewer, and analytical error is big; Syringe inwall meeting adsorption sample gas causes the loss of sample gas; Cause the bottle internal gas pressure to reduce during sampling and cause the not enough defective of actual sample tolerance.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: comprise bottle and the plug that matches with bottle; Described plug is provided with sampling pipe, air intake duct, inert gas inleting pipe, described sampling pipe, air intake duct, inert gas inleting pipe all are connected with bottle inside, be used for connecting the inside and outside gas of bottle, the end that described air intake duct stretches in the bottle also is provided with air bag.
The invention has the beneficial effects as follows: during test same amount pedotheque, the gaseous sample amount is bigger, and it is less to reduce analytical error; Directly in the sampling of the sampling mouth of pipe, can not cause gas loss; And there is air bag, when sampling, because extraneous air can enter the silica gel air bag with the air pressure in the equilibration flask, the bottle internal gas pressure reduced cause actual sample tolerance.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described sampling pipe, described air intake duct, described inert gas inleting pipe are teflon material, and this material character is stable, can not react with mercury.
Further, described air bag, described plug are the silica gel material, adopt the silica gel material, can tool
Better seal and the property upheld and stable in properties are arranged.
Further, described sampling bottle also comprises aspiration pump, and described aspiration pump links to each other with described sampling pipe.
Adopt the beneficial effect of above-mentioned further scheme to be: when bleeding, aspiration pump and sampling pipe are connected, convenient sampling.
Description of drawings
Fig. 1 is front view of the present invention;
In the accompanying drawing, the list of parts of each label representative is as follows:
1, sampling pipe, 2, air intake duct, 3, the silica gel air bag, 4, inert gas inleting pipe, 5, plug, 6 pedotheques.
Embodiment
Below in conjunction with accompanying drawing principle of the present invention and feature are described, institute gives an actual example and only is used for explaining the present invention, is not for limiting scope of the present invention.
As shown in Figure 1, the plug 5 that the present invention includes bottle and match with bottle, described plug 5 is provided with sampling pipe 1, air intake duct 2, inert gas inleting pipe 4, described sampling pipe 1, air intake duct 2, inert gas inleting pipe 4 connect the inside and outside gas of bottle, and the end that described air intake duct 2 stretches in the bottle is provided with silica gel air bag 3.Described sampling pipe 1, air intake duct 2, inert gas inleting pipe 4, plug 5 used materials all do not react with mercury, and wherein sampling pipe, air intake duct, inert gas inleting pipe are teflon material, and air bag, plug are the silica gel material, stable in properties; Sampling pipe is used for the sampling that contains mercury gas that pedotheque discharges in the bottle; Air intake duct is that the bottle internal gas pressure reduces the passage that the back outside air enters air bag when gathering gaseous sample; Inert gas inleting pipe connects the inert gas bottle, for inert gas injecting in bottle.The silica gel air bag is used for taking in air, by the expansion of air bag, guarantees that the narrow-mouthed bottle internal gas pressure is constant during sampling; When inert gas entered narrow-mouthed bottle, air bag restored to the original state gradually.
The course of work of the present invention: an end that stretches in the bottle at air intake duct 2 is provided with silica gel air bag 3, during gaseous sample, aspiration pump is connected sampling pipe in the collecting bottle, and inert gas inleting pipe is closed, outside air enters the silica gel air bag by draft tube during sampling, air bag is expanded, guarantee that the sampling bottle internal gas pressure is constant, sampling is closed sampling pipe after finishing, open the inert gas bottle, inert gas enters in the bottle, and air is discharged sampling bottle in the air bag, and air bag is closed inert gas inleting pipe after restoring to the original state.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
