Abstract
The utility model relates to a sampling head used for collecting air pollutant, which is formed by the reform on the basis of the present atmospheric sampling head. A filter material barrel is assembled between a filter membrane frame and an air receiving pipe, and polyurethane foam adsorbent of the filter membrane with glass fibers can be arranged in the filter material barrel. The utility model can be used for collecting pollutant such as atmospheric particulates, full-dose polycyclic aromatic hydrocarbon, polychlorinated biphenyl, low molecular organochlorine, etc., and can also be used for collecting suspended matters, polycyclic aromatic hydrocarbon, etc. when pollutant in water is measured. The utility model which has small size, simple structure, convenient operation and convenient carrying is an ideal device for protecting and monitoring environment.
Description
The utility model is a kind of sampling head of gathering atmosphere pollution, is mainly used in particle and the palycyclic aromatic gathered in the atmosphere.
The particle of gathering in the atmosphere at present still adopts filter membrane method, generally uses the funnel type sampling head of laying glass fiber filter, captures the particle in the atmosphere.The palycyclic aromatic of gathering in the atmosphere also uses the same method, but benzo (a) pyrene (5 phenyl ring) of the absorption on the analysing particulates thing only.Polyaromatic hydrocarbon pollutant in fact, by the compound that 2-7 phenyl ring forms, only some is adsorbed on the particle in atmosphere, and another part then is gaseous state and exists, along with the reduction of phenyl ring number, and the rising of environment temperature, the ratio of gaseous state amount increases.Gaseous PAHs is strong owing to inhalable, thereby bigger to harm.Because filter membrane is to not capture effect of gaseous PAHs, leak filter from filter membrane during collection, so with filter membrane method adopt polycyclic aromatic hydrocarbon only be that part that is adsorbed on the particle.For adopt the gaseous state palycyclic aromatic, generally adopt solvent absorption or condensation at low temperature again, and these methods are unsuitable for field operation in the filter membrane back.A kind of method is arranged at present, adopt polyurethane foam as adsorbent, adsorb the polycyclic aromatic hydrocarbon in the atmosphere, its adsorption efficiency reaches more than 90%, and this adsorbent is home products, but does not also have supporting sampling head.
The purpose of this utility model provides a kind of sampling head that can lay filter membrane and polyurethane foam adsorbent, it not only can be gathered simultaneously the particle in the atmosphere and leak the gaseous PAHs pollutant of filter, also can be used for separately gathering particle or full dose polycyclic aromatic hydrocarbon pollutant in the atmosphere.
The utility model is achieved in that this device forms in the transformation of the way of the basis of existing sampling head, is assembled with the filtrate tube between filter membrane frame and trachea.When gathering two kinds of pollutants, lay glass fiber filter at the filter membrane frame, put into the polyurethane foam adsorbent in the filtrate tube.When gas passed through sampling head, the polycyclic aromatic hydrocarbon that adsorbs on the particle in the atmosphere and the particle was captured by filter membrane, was adsorbed the agent capture and leak the gaseous PAHs of filtering from filter membrane.Not only can measure the amount of the particle that captures on the filter membrane, and can analyze the amount of the gaseous PAHs of the polycyclic aromatic hydrocarbon that is adsorbed on the particle and Capture by Sorbents During, thereby obtain the amount of full dose polycyclic aromatic hydrocarbon.In the time need not gathering in the atmosphere particle, can not lay filter membrane, only need in the filtrate tube, to place adsorbent and sample, also can not lay the filter membrane frame, only with the filtrate tube that the polyurethane foam adsorbent is housed and trachea sampling, just can gather the full dose polycyclic aromatic hydrocarbon pollutant.Filter membrane frame of the present utility model, filtrate tube and trachea can adopt the screw thread assembling or insert and be assembled into one.Filter membrane frame and filtrate tube can be made one, utilize with the connection place of trachea and lay filter membrane, also filtrate tube and trachea can be made one, the full dose polycyclic aromatic hydrocarbon uses in the atmosphere as gathering separately.
Because the utility model is made up of filter membrane frame, filtrate tube and trachea, so it is simple in structure, volume is little, carry easy to operate, so the use of can sampling in any environment.It can gather particle and full dose polycyclic aromatic hydrocarbon in the atmosphere simultaneously, saves the sampling time, also can gather separately wherein a kind of pollutant, and practicality is extensive; Its resistance of polyurethane foam adsorbent that adopts is little, can be selected to various sampling pumps, because this adsorbent is to the Polychlorinated biphenyls in the atmosphere, low molecule organochlorine etc. has suction-operated, adding also has suction-operated to organic matter in the water outward, so the utility model also can be used for the sampling of the pollutant such as Polychlorinated biphenyls and low molecule organochlorine in the atmosphere, can also be for organic pollutions such as the polycyclic aromatic hydrocarbon of gathering sewage, agricultural chemicals; Only lay filter membrane and also can gather suspension in the sewage.It is the ideal equipment of environmental protection and monitoring.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a kind of concrete structure synoptic diagram of the present utility model.
Fig. 2 is that the utility model is not with the structural representation of filter membrane frame.
The utility model is made of filter membrane frame 1, filtrate tube 5 and trachea 6.Filter membrane frame 1 is infundibulate, and the quarrel end has the screen cloth 3 that supports filter membrane and is contained in the press mold circles 4 above the screen cloth 3 and is screwed in press mold lid 2 in the quarrel; The bucket bottom sheet connects filtrate tube 5.Filtrate tube 5 for always the tube, its two ends are connected with filter membrane frame 1 and trachea 6, trachea 6 connects sampling pump.Unload lower pressed film lid 2 and press mold circle 4 during sampling earlier, filter membrane is placed on the screen cloth 3, put press mold circle 4 filter membrane is pushed down, prevent to cover and filter membrane is screwed fragmentation at 2 o'clock screwing press mold, screw on press mold lid 2 then.Unload trachea 6(and also can unload the filter membrane frame), the polyurethane foam adsorbent is put into filtrate tube 5, again trachea 6 is loaded onto, connect sampling pump (source of suction) and just can sample.Atmosphere enters sampling head under the effect of sampling pump suction, particle and the polycyclic aromatic hydrocarbon that is adsorbed on the particle are captured by filter membrane when filter membrane frame 1, and the gaseous PAHs that leaks filter from filter membrane is adsorbed agent absorption with airflow passes filter cylinder 5.After sampling finishes, measure earlier the amount of the particle that captures on the filter membrane, and then analyze the amount that is adsorbed on the polycyclic aromatic hydrocarbon on the particle that captures on the filter membrane, add with the amount of the gaseous PAHs of Capture by Sorbents During and, both obtained the amount of full dose polycyclic aromatic hydrocarbon in the atmosphere.Only just can measure the content of two kinds of pollutants in the atmosphere through once sampling.If only need gather the particle in the atmosphere, just only lay filter membrane at filter membrane frame 1; Only gather the full dose polycyclic aromatic hydrocarbon in the atmosphere, just only in filtrate tube 5, lay adsorbent; Also can be filtrate tube 5 and trachea 6 as the sampling head of gathering the full dose polycyclic aromatic hydrocarbon, the front can not fill filter membrane frame 1, places the polyurethane foam adsorbent in filtrate tube 5, connects source of the gas and can gather full dose polycyclic aromatic hydrocarbon in the atmosphere.
