Embodiment 2
[0049] Embodiment two: a kind of detection method of indoor volatile pollutant, comprises the following steps:
[0050] Step 1, selection of sampling points: Under normal conditions and environments, select sampling points as follows:
[0051] One sampling point is set at each corner of the room;
[0052] Set a sampling point in the middle of the room;
[0053] Step 2, sampling: place the sampling box 1 at the position to be sampled, open the cover plate 23, drive the bottom cover 3 and the cover body 31 up and down through the lifting cylinder 11, separate the cover body 31 from the bottom cover 3, and make the cover body 31 Both the bottom cover 3 and the bottom cover 3 are exposed to the air at the position where it is used, and it is left to stand for a period of time, so that the gas between the cover body 31 and the cover plate 23 is basically consistent with the air composition around the sampling point, and then the cover body 31 is sealed and connected to the bottom ...

The invention relates to a detecting device for indoor volatile pollutants. The device comprises a sampling assembly and a detecting assembly, wherein the sampling assembly comprises a sampling box; astoring chamber is vertically formed in the upper side of the sampling box; a bottom cover is horizontally arranged on the bottom surface of the storing chamber; a cover body which is detachably connected to the bottom cover in a sealing manner is arranged at the upper side of the bottom cover; a lifting cylinder capable of pushing the bottom cover to protrude from the upper end of the storing chamber is fixedly connected to the lower side of the bottom cover; a cover plate capable of sealing and closing the storing chamber is arranged on the upper side of the storing chamber; a hot air conveying device for conveying hot air into the storing chamber is arranged at a position, corresponding to one side of the storing chamber, of the sampling box; a cold air conveying device for conveying cold air into the storing chamber is arranged at a position, corresponding to the other side of the storing chamber, of the sampling box. The device has the effect of improving the detection data authenticity.
Description
technical field [0001] The invention relates to the technical field of air detection, in particular to a detection device and a detection method for indoor volatile pollutants. Background technique [0002] With the development of the home decoration industry in recent years, various building materials are widely used, and the indoor environmental pollution is also becoming more and more serious. The level of some pollutants indoors is much higher than outdoors, especially volatile organic compounds (VOCs) in new homes, such as aromatic hydrocarbons (benzene, toluene, xylene, etc.), ketones, aldehydes, ammonia and amines, etc. , its concentration is enough to pose a hazard to human health. The American Lung Association lists five primary pollutants as cigarette smoke, VOC, formaldehyde, mold dust and carbon monoxide. It believes that the main pollutants in indoor air include inhalable particulate matter, aerosol , jump, NOx, C0, C02, ammonia, formaldehyde, VOC, PAHs, nicoti...
