Technical field
The utility model relates to the gathering-device of mercury element in the gathering-device of trace element in a kind of cigarette mainstream flue gas, particularly cigarette mainstream flue gas, belongs to the flue gas analysis technical field.
Background technology
Along with the pay attention to day by day of people to health problem and environmental problem, the detection of trace element is subjected to paying close attention to widely in cigarette and the cigarette smoke.The cigarette generation flue gas that at high temperature burns, cigarette smoke is a kind of complicated aerosol system that comprises 5000 multiple gases and particulate composition, comprising harmful mercury element, can cause certain harm to human body along with flue gas enters human body.
The flue gas of cigarette is divided into two kinds, and a kind of is the flue gas of cigarette burning end, and another kind of cigarette is inhaled the flue gas of end, and the flue gas of wherein inhaling end becomes main flume.At present in cigarette mainstream flue gas in the assay of mercury element, capture main flume effectively and be the committed step in the flue gas analysis.Capture mode commonly used has cambridge filter trap, static trap, sprays bump trap and solvent trap etc.Wherein cambridge filter is not suitable for elementary analysis because background is higher; The static trap can be used for elementary analysis, but can generate the artifacts because of discharge generation ozone; Spray bump trap injection bump trap and can be used for medium and quantitative analysis low volatility materials, its advantage is the granule phase substance that can produce a large amount of easy wiring solution-formings, and shortcoming is easily to result in blockage, and needs accurately to control flow and pressure; The structure of solvent trap is comparatively simple, and is better to the assimilation effect of metallic element and volatile materials.China Patent No.: ZL200720091565.0 discloses the capturing device of VOC in a kind of cigarette mainstream flue gas, this device comprises the solvent absorption plant with inlet end and outlet side, inlet end is in series with adsorption tube by polyfluortetraethylene pipe, is used to absorb interfering compound; The solvent absorption plant is an absorption bottle, this absorption bottle comprises the bottle cap and the bottle of removable seal assembling up and down, also comprise the escape pipe that is communicated with bottle cap and insert the air inlet pipe that stretches into when wearing bottle cap and absorption bottle assembling in the bottle that described air inlet pipe is inserted end in the bottle and is provided with the micropore structure of giving vent to anger.The general capturing device other end of adsorption tube in use connects trap, by the rotating disc type smoking machine main flume is blown into capturing device and captures.Adopt the capturing device of said structure to have following problem: cigarette mainstream flue gas at first enters smoking machine and trap, test substance in the main flume remains on smoking machine and the trap easily, impact when easily follow-up sample being captured, make final measurement result produce deviation, the reappearance that influence is measured, need before each mensuration, clear up smoking machine and trap, the efficient that influence captures, and use very inconvenient; And adopt an absorption bottle to tend to cause absorption insufficient, influence final measurement result.
The utility model content
The purpose of this utility model provides the gathering-device of mercury element in a kind of cigarette mainstream flue gas easy to use, to improve the efficient that captures.
In order to realize above purpose, the technical scheme that the utility model adopted is: the gathering-device of mercury element in a kind of cigarette mainstream flue gas, comprise solvent absorption plant with inlet end and outlet side, also comprise cigarette clamper and smoking apparatus, this cigarette clamper is connected with the outlet side with the inlet end of solvent absorption plant by connecting pipe respectively with smoking apparatus, is in series with cambridge filter between described solvent absorption plant and the smoking apparatus.
Be in series with hemispherical glass frosted interface respectively between described cigarette clamper and the solvent absorption plant and between smoking apparatus and the solvent absorption plant.
Described solvent absorption plant is made up of the absorption bottle of two series connection, is in series with hemispherical glass frosted interface between two absorption bottles.
Described absorption bottle comprises the air inlet pipe of inserting when using in the bottle, and the end of this air inlet pipe is provided with the throttling structure of giving vent to anger.
Described throttling is given vent to anger structure for closing up.
Described connecting pipe is a polyfluortetraethylene pipe.
The gathering-device of mercury element in the capture cigarette mainstream flue gas of the present utility model, main flume at first feeds in the absorption liquid of solvent absorption plant under the swabbing action of smoking apparatus, mercury element in the main flume is absorbed in the absorption liquid, avoided mercury element to be measured residual on smoking machine, can realize continuous capture to sample, improved the efficient that captures, very easy to use.And unabsorbed particle of main flume and unnecessary acid gas and material are absorbed by cambridge filter, can prevent that residue in the main flume from entering smoking machine it is caused damage; And between cigarette clamper, absorption bottle, smoking apparatus and two absorption bottles, all be in series with hemispherical glass frosted interface, purpose is the refluence that prevents gas, content to the mercury element that absorbed in the absorption bottle impacts, but also can not cause the loss that causes element to be measured because of the suck-back of solvent.
In addition, the utility model adopts the solvent absorption plant of two absorption bottle series connection, compare single absorption bottle, mercury element in the cigarette mainstream flue gas can fully be absorbed, compare the absorption bottle more than three or three, can avoid the pressure drop of suction channel excessive, and aspiration procedure is exerted an influence, improve the collection quality of gathering-device mercury element.
In addition, the closing in that the outlet side of absorption bottle is provided with can make main flume enter absorption liquid and form less bubble, has increased the contact area of main flume and absorption liquid, has improved the assimilation effect of absorption liquid to mercury element in the main flume; In addition, the connecting pipe between each parts has adopted polyfluortetraethylene pipe, and compare glass tube and have higher corrosion resistance, but also not fragile, improved the security that gathering-device uses.
