Abstract
The invention discloses a ring type volatile organic compound (VOC) acquiring device. The device comprises a shell 10, a heating device 20, a gas collecting device 30 and a fixing device 40, wherein the outer wall of the shell has a high thermal insulation property; the gas collecting device is positioned in a cavity of the shell or is integrated with the shell; the heating device is positioned in a sandwich layer of the shell or arranged on the inner wall of the shell and can be used for heating a sample in a lossless manner; and the fixing device can be used for providing insufficient fixing capability for flatly placing the device on the ground, arranging the device on a side wall, inversely arranging the device on a ceiling and using the device on a cylindrical surface. The device has high environment adaptability, and a VOC is convenient to acquire on site in the lossless manner.
Description
Technical field
The present invention relates to a kind of gas collecting device, particularly a kind of VOC sampling box that is applicable to spot sampling in various venues.
Background technology
Because the interpolation of auxiliary agent in the commercial production, be VOC through the residual VOC of having of regular meeting in many products.And VOC can cause the pollution of environment, and human body is produced serious harm.Therefore content that must strict control VOC makes it not and can pollute and endanger environment.
In test items such as gas composition analysis, smell test, need a kind of equipment and can carry out gas sampling.For example, in the VOC test, normally determinand is cut and be suitable size; Pack in the sack of special substance, put into baking oven, with suitable temperature baking a period of time; VOC in the determinand is evaporate in the sack, extract the gas in the sack then, process machine test on the sample.
This method belongs to and diminishes detection, need determinand be destroyed, and the product that is used for general batch process is suitable, but just seems for determinand large-scale, that can not destroy and to be difficult to meet the demands.For example, indoor sport venue, synthetic court etc. are carried out VOC detect, needing can be under the prerequisite of not destroying the place, the volatile organic matter of field ground surface is carried out collection in worksite at the scene.
Summary of the invention
In order to overcome above technical matters, the present invention adopts ring type VOC harvester that VOC is carried out the harmless collection in scene.This device comprises shell 10, heating arrangement 20, gas extractor 30, stationary installation 40, can realize the spot sampling to VOC gas.
Shell 10 outer wall heat-proof qualities are good, can holdout device inside and outside heat interchange, said heating arrangement 20 is infrared lamp or the heating wire in the shell interlayer that place on the outer casing inner wall.
Gas extractor 30 is airbags, and the chemical property of airbag should be more stable, all with VOC chemical reaction does not take place under normal temperature and the higher temperature, and heat transfer property is good; Airbag places in the housing, and opening part connects packoff, has the pore that matees with valve on the airbag, and valve one end is installed on the pore, and the other end is connected with the air pump air intake opening through silicone tube.
Gas extractor 30 and shell 10 are as one, and the outer casing inner wall stable chemical performance all with VOC chemical reaction does not take place under normal temperature and the higher temperature, and heat resistance is better; Have the pore that is complementary with valve on the shell, valve is connected with the air pump air intake opening through silicone tube 60.
Fastening pawl grip end surface rigidity is less, is not caused damage to grabbing object.
Description of drawings
Fig. 1 is a VOC harvester system schematic;
Fig. 2 is the stationary installation synoptic diagram that shaft-like sample is sampled;
Among the figure: shell 10 heating arrangements 20 stationary installations 40 hollow toroidal shell 441 bevel pinions 442 are removed son 443 fastening pawl 444 bevel gear wheels 445
Embodiment
Stationary installation as shown in Figure 2 is connected with sampling apparatus shell 10 through screw thread, and connects the silicone tube of each position.
Shell 10 adopts the PE material, and chemical stability is high, and corrosion-resistant and temperature range can reach 80～100 ℃.Shell has only an opening, and outer wall section is coated with thermofin, can holdout device inside and outside heat interchange, guaranteed the efficiency of heating surface.Shell 10 also serves as gas extractor 30 simultaneously, has the pore that is complementary with valve on it, and valve one end is installed on the pore, and the other end is connected with the air pump air intake opening through silicone tube 60.Heating source is the resistance wire 22 that is embedded in the shell.
During sampling, earlier device is fixed on the sample surfaces.Earlier sample surfaces is cleared up before the sampling, then the hole of shaft-like sample through bottom of device put in the device.Remove son on the turn stationary installation, bevel pinion also rotates thereupon, and drives bevel gear wheel rotation in vertical direction.And the helicla flute on bevel gear wheel surface drives down, three entad direction of principal axis slips of fastening pawl, at last firmly clamp on sample.Can dispose O-ring seal this moment on stationary installation, prevent gas leak.Energized heats sample area subsequently.Along with the carrying out of heating, sample area can disengage VOC gradually.This part of V OC will scatter in gas extractor, up to reaching the predetermined heating time limit.After this stop to heat and open the VOC that air pump will disengage and from gas extractor, extract and preserve, accomplish the collection in worksite of VOC.
The above; Only be in order to practical implementation case of the present invention to be described; But be not in order to limit practical range of the present invention; Such as those skilled in the art must be covered by the scope of claim of the present invention not breaking away from all equivalence changes of being accomplished under indicated spirit of the present invention and the principle or modifying.
