The apparatus has good environmental adaptability and is convenient for on-site lossless acquisition of VOC.
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 VOC (volatile organic matter) test, normally determinand is cut and be suitable size; Pack in the sack of special substance; Put into baking oven, the temperature baking a period of time with suitable, the 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 VOC collection in worksite device that VOC is carried out the harmless collection in scene.
This VOC collection in worksite device comprises shell 10, heating arrangement 20, gas extractor 30, stationary installation 40; Said gas extractor 30 and shell 10 are as one, and said shell has only an opening, and fit like a glove with the opening of gas extractor; Outer casing inner wall does not discharge VOC and with VOC chemical reaction does not take place; Have the pore that is complementary with valve on the shell, valve is connected packoff through silicone tube 60 with the air pump air intake opening and is positioned at the shell aperture place.
Preferred scheme is:
Said shell 10 outer walls adopt insulation material, can the inside and outside heat interchange of holdout device, and said heating arrangement 20 is the heating wire 22 in infrared lamp 21, microwave applicator or the shell interlayer that places on the outer casing inner wall.
Shell 10 open front are equipped with and closely connect with it and the good deformable flexible glue 51 of elasticity, and when sucker absorption plane, flexible glue can fit tightly in the plane.
Harvester also can comprise the packoff 50 of independent setting, and its form is changeability flexible glue 51 or O-ring seal 52.
Use VOC collection in worksite device provided by the invention, can carry out the harmless sampling in scene of VOC, avoided the destruction of traditional VOC sampling process determinand to determinand large-scale, that can not destroy.Carry VOC collection in worksite device to venue to be sampled by operating personnel, sampling box is covered on the surface of determinand, form seal cavity, wait the VOC of determinand slowly to get into gas storage space, take out test and get final product.Stationary installation can keep flat on ground for device, places at sidewall, enough crystallized abilities are provided being inverted on the ceiling and on the face of cylinder, using.This device has good environmental suitability, is convenient at the scene VOC can't harm collection.
Description of drawings
Fig. 1 is a VOC harvester system schematic;
Fig. 2 is the VOC harvester synoptic diagram (to the side elevation sampling) of embodiment 1;
Fig. 3 is the VOC harvester synoptic diagram of embodiment 2;
Among the figure: shell 10 heating arrangements 20 infrared lamps 21 resistance wires 22 gas extractors 30 airbags 31 stationary installations 40 suckers 41 dull and stereotyped 42 seamless double faced adhesive tape 43 packoffs 50 deformable flexible glues 51 O-ring seals 52
Embodiment
Embodiment one
Like Fig. 2, the shell that comprises heating arrangement 22 10, stationary installation 40, silicone tube 60 are connected successively.
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 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, the flat board that will install then is pressed on the sample surfaces, and double faced adhesive tape is sticked on the sample, and whole device will be combined closely with the surface this moment.This moment, but energized heated sample area.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.
Embodiment two
Like Fig. 3, shell 10, heating arrangement 20, airbag 31, stationary installation 40, packoff 50 are connected successively.
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, has insulating sandwich, can holdout device inside and outside heat interchange, guaranteed the efficiency of heating surface.Airbag 31 is arranged in the cavity of shell 10, 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.Airbag material chemical stability is high, and corrosion-resistant and temperature range can reach 80～100 ℃.Shell has only an opening, has insulating sandwich, can holdout device inside and outside heat interchange, guaranteed the efficiency of heating surface.Heating source is the infrared lamp 21 that is installed on the outer casing inner wall.
