Abstract
The utility model discloses a kind of subsoil water passive sampling apparatus, it is characterised in that include the outer sleeve being made up of the outer sleeve protective cover 3 of outer sleeve upper cover 1, outer sleeve lower cover 2 and stainless (steel) wire establishment with perforate；Also include the capsula interna being made up of non-woven fabrics；Having capsula interna clip and thief hatch in capsula interna upper end, capsula interna is placed in outer sleeve, and its clip and thief hatch are exposed by the opening of outer sleeve upper cover 1.This utility model can solve to be widely deployed in the purpose of the cheap sampling apparatus of contaminated site and undisturbed collection groundwater sample.
Description
Technical field
This utility model relates to a kind of passive sampling apparatus for gathering subsoil water.Belong to the ring in field of environment protection
Sample devices field, border.
Background technology
Along with China's attention to environment monitoring industry, especially " water prevention and cure of pollution action plan ", " Soil Pollution Control
Action plan " issue and the carrying out of auxiliary work, the various sample devicess for Field of Groundwater Study present the situation of blowout.This
Groundwater sampling equipment is many a bit realizes based on centrifugal pump, displacement pump or inertial pump's principle.
The sample devices generally using pump principle to gather groundwater sample all exists that sample hoisting depth is limited (is common in base
In vacuum, displacement pump, the sample devices of inertial pump's principle), lifting process causes water sample leakage and sample because of pipe breakage
Course of conveying contacts with external substance and causes cross-contamination, impure sample wearing terrain (to be common in employing centrifugal pump, volume
The equipment of pump principle) etc. shortcoming.Upper all there is employing passive sampling equipment to this end, internal and international, utilize special material, only allow
Specific objective pollutant pass through and enter in collection container.Such as patent of invention " a kind of persistence organic pollutant passive
Sampling apparatus " (Authorization Notice No. CN 204439408 U) make use of semipermeable membrane principle, and only control and allow persistency organic
Pollutant enter in collection capsule；Patent of invention " water plant fat-bionical passive sampling of cellulose acetate composite semi-permeable membrane
Device " (Authorization Notice No. CN 102895887 A) also with modified semipermeable membrane principle realize to specify pollutant quilt
Dynamic sampling.But this passive sampling apparatus based on semipermeable membrane principle is generally of following shortcoming: one is to need balance
Time is the longest, because the concentration difference that pollutant itself rely only on film device both sides realizes just permeating, infiltration rate is controlled by film
The size and number of upper channel；Two are the hydrodynamic characteristic of semipermeable membrane devices itself and soil porous media differs greatly,
It is susceptible to blocking；Three is that film device mostly is single use, after collection cannot clean and reuse recycling, can only abandon or manually
Degraded.
Summary of the invention
The purpose of this utility model is to provide a kind of subsoil water passive sampling apparatus, to solve to be widely deployed in pollution
The purpose of the cheap sampling apparatus of place and undisturbed collection groundwater sample.
In order to realize foregoing invention purpose, the technical scheme that this utility model is used is as follows:
A kind of subsoil water passive sampling apparatus, including by with the outer sleeve upper cover 1 of perforate, outer sleeve lower cover 2 and stainless
The outer sleeve of outer sleeve protective cover 3 composition of steel mesh establishment；Also include the capsula interna 6 being made up of non-woven fabrics；In capsula interna 6 upper end has
Capsule clip 4 and thief hatch 5, capsula interna 6 is placed in outer sleeve, and its clip and thief hatch are revealed by the opening of outer sleeve upper cover 1
Go out.
Outer sleeve protective cover 3 is made up of 304 stainless (steel) wires scribbling Teflon.
Non-woven fabrics material grams should be higher than that 80g.
A kind of subsoil water passive sampling apparatus described in the utility model, changes domestic existing subsoil water passive sampling and sets
Standby based on permeable membrane principle, with high-density non-woven fabrics replacement, compare existing device and have the advantages that one is to use nonwoven
Cloth substitutes specific semipermeable membrane, it is possible to gather all of pollutant in subsoil water；Two is that non-woven fabrics hydrodynamic characteristic is close
Soil porous media, equilibration time is shorter, is suitable for the sampling of quick place；Three is that housing uses stainless steel to have certain machine
Tool intensity, device design simultaneously is simple, with low cost, only need to reequip on the basis of existing filtering material complete set of equipments, have and make
The advantage that valency is cheap, easy to use, has the biggest promotional value.
Accompanying drawing explanation
Fig. 1 is the outer sleeve structure schematic diagram of apparatus of the present invention.
Fig. 2 is the capsula interna structural representation of apparatus of the present invention.
Fig. 3 is structural representation of the present utility model.
In figure number: 1 be the outer sleeve upper cover with perforate, 2 be outer sleeve lower cover, 3 be stainless (steel) wire work out overcoat
Cylinder protective cover, 4 be capsula interna clip, 5 for thief hatch, 6 be non-woven fabrics capsula interna.
Detailed description of the invention
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment with existing
In having technology to describe, the required accompanying drawing used is briefly described.It should be evident that the accompanying drawing in describing below is only this
Inventive embodiment, for those of ordinary skill in the art, on the premise of not paying creative work, according to the present invention
Product after modifying still should be regarded as within this patent protection domain.
Seeing shown in Fig. 1,2,3, a kind of subsoil water passive sampling apparatus, by with the outer sleeve upper cover 1 of perforate, outer sleeve
The parts such as the outer sleeve protective cover 3 composition outer sleeve of lower cover 2, stainless (steel) wire establishment, outer sleeve uses and scribbles the 304 of Teflon not
Rust steel.Capsula interna 6 is formed by non-woven fabrics.It is provided with capsula interna clip 4 and thief hatch 5 at capsula interna 6 top.
This utility model complete component is divided into outer sleeve and capsula interna, and outer sleeve is made up of upper and lower covers and outer sleeve protective cover,
Capsula interna is made up of non-woven fabrics, and there are capsula interna clip and thief hatch in capsula interna upper end.Protective cover is by 304 stainless (steel) wires scribbling Teflon
Composition.Non-woven fabrics material does not limits, but grams should be higher than that 80g.Capsula interna is for disposably can abandon, and external capsule is reusable.
Contain non-aqueous phase liquids pollutant (NAPLs), heavy metal and the ground of water-soluble organic pollutant gathering certain simultaneously
As a example by lower water, standard technology is first used to set up sampled well.Complete after shaft building through well-flushing recovery water levelx, by non-woven fabrics capsula interna 6
Put into urceolus protective cover 3, and tighten outer sleeve upper cover 1, outer sleeve lower cover 2.Hawser is buckled on capsula interna clip 4, and by whole
The individual parts assembled are put in well, and during sampling, water is entered from capsula interna infiltration.Equilibration time 48h, and whole device is proposed well
After Kou, gather groundwater sample analysis by thief hatch 5.Clip 4, through outer casing upper cover, is used for mentioning.In sampling
After having worked, described capsula interna can be abandoned, and described outer sleeve is reusable after rinsing.
