In addition, service life of the breeze type air sampler depends on that of the fan which can be replaced, and household users can take samples by themselves.
Description
Technical field:
The utility model relates to a kind of gentle breeze formula air sampler, and it belongs to architectural environment air monitering technical field.
Background technology:
Because building materials, ornament materials, furniture, household electrical appliances have used the material that contains VOC and formaldehyde in a large number when producing; VOC: be meant under normal pressure; The various organic compounds that boiling point is 50～260 ℃ mainly comprise: benzene,toluene,xylene, ethylbenzene, styrene etc.In use subsequently, can progressively discharge the pollution indoor air environment.In the environment that VOC or formaldehyde exceed standard, live, symptoms such as ocular pain, sore-throat, headache, tired out sense, dysphoria appear in the man-hour regular meeting of work, study, are referred to as " sick building syndrome ", can cause the dirty impaired or leukaemia of a plurality of devices when serious.In order to guarantee the health of human living environment, will not check and accept for the newly-built, renovating and enlarging building that exceeds standard at pollutants such as VOC or formaldehyde.But,, be difficult to large tracts of land in the practice and promote because testing cost is higher for house decoration.Main cause under testing cost is in not is: the detection method that the acceptance of work is at present adopted is the active air sampler method of sampling, needs the testing staff to carry instrument and equipment and samples to the scene, needs to consume a large amount of manpowers and time.
Existing air sampling rig has following several kinds:
Active air sampler: through asepwirator pump and air-flow measurement device, the air sample with certain volume in the regular hour passes through the absorbing medium in the gatherer, and gas pollutant is concentrated in the absorbing medium, and reaches the purpose that concentrates sampling.Just can detect the VOC concentration in the surrounding air to be detected with instrument logotypes such as gas chromatographs.
Passive type air sampler: be based on a kind of method of sampling that gas molecule diffusion or penetration theory are gathered gaseous state in the air or steam-like pollutant; It does not have asepwirator pump and air mass flow metering device; Lean on its adsorbent is exposed to certain hour in the air (sampling time), make that a part of VOC is adsorbed in the adsorbent in the air.In sampling time fixedly the time, VOC concentration is directly proportional in the adsorbance of adsorbent and the air; VOC concentration one timing in air, adsorbance was directly proportional with the sampling time.Note the sampling time during use, can measure adsorbance with instrument logotype such as gas chromatograph, again through with various normal concentration down-samplings, detect the mass data that obtains and compare, just can detect the VOC concentration in the surrounding air to be detected.
The ultimate principle of passive adsorbing and sampling device is passive type absorption, and its main points are: all can seal before and after the sampling adsorbent, only sampling period the chien shih adsorbent be exposed in the air.
There is following shortcoming in the passive type sampling apparatus: 1) sampling time long, generally to sample at least 8 hours; 2) when containing the lower environment of VOC and sample, the VOC adsorbance is on the low side, influences accuracy of detection; 3) rubber seal itself tends to discharge VOC, influences measuring accuracy.The passive type method of sampling can reduce the detection cost significantly, but because the sampling time is long, accuracy of detection is low, thereby not widespread use as yet.
Active sampling thief costs an arm and a leg, must be by professional testing staff operation, so labour cost, depreciation of equipment and transportation expenses just make and detect cost and be difficult to significantly reduce, make many families hope Indoor Environment Detection and draw back.
Gentle breeze formula air sampler: a kind of supplementary instrument; On the basis of passive type air sampler; Increase the device that makes air flow; Adsorbable more VOC in the identical time, or make the abundant VOC of adsorbents adsorb in the short period of time, can effectively improve accuracy of detection or improve sampling efficiency.But also there is not ripe gentle breeze formula air sampler technology to utilize in the prior art.
Summary of the invention:
It is a kind of simple in structure, easy to use that the purpose of the utility model is to provide, and use cost is low, and testing result is gentle breeze formula air sampler accurately.
A kind of gentle breeze formula air sampler; It comprises granular pattern adsorbent, medicament cage, base; Described adsorbent is filled in the medicament cage, and described medicament cage is arranged on the base, on described base, connects an air duct; Described air duct is a tubular structure, in the top or the bottom of described air sampler an instrument fan is set.
Described air duct is a tubular structure that top is wide-mouth, and described instrument fan is arranged on the top position of wide mouth of air duct, and is provided with air inlet in the bottom of air duct.
Described air duct is that a top is the tubular structure that closes up, and its closing in place is a fresh air inlet; The bottom of described base is the wide-mouth structure, and described instrument fan is arranged on the below of bottom wide-mouth, and is provided with air inlet on the top of base.
Its top of described base is provided with and is used for circular small boss that the medicament cage installs and is used for the circular big boss that web member is installed, and is equipped with on the large and small boss to be connected required screw thread or bayonet socket with web member.
Described base is the teflon or the food-grade polyethylene of hard.
Described adsorbent can be selected activated charcoal or molecular sieve for use.
Described medicament cage is that perforated metal or wire netting are made, and it is shaped as cylindrical structural.
On described medicament cage, be provided with stopper.
The utility model forms air-flow around the medicament cage, can increase substantially accuracy of detection, improve detection efficiency, and it is simple in structure; Volume is less; Processing cost and use cost are all cheaper, and depend on the life-span of fan the serviceable life of the utility model, and fan is replaceable.The utility model operation is simpler in addition, and the domestic consumer can sample voluntarily, and detection efficiency is high.
