Abstract
The utility model discloses a high-efficiency small-size porous glass-tube type absorption bottle. The high-efficiency small-size porous glass-tube type absorption bottle comprises a gas inlet, a gas outlet, a gas inlet pipe, an absorption tube and a porous glass plate; the porous glass plate is arranged on the lower part of the absorption tube; the inner wall of the absorption tube is provided with spiral heaves through which gas bubbles can ascend spirally; and the spiral heaves of all circles are thinned at spiral intervals from the lower end to the upper end of the absorption tube. Because the way of absorbing the gas bubbles by making the gas bubbles ascend lineally is changed into the way of absorbing the gas bubbles by making the gas bubbles ascend spirally, the upward moving speed of the gas bubbles can be decreased, more gas bubbles can be absorbed, the gas-bubble absorbing time can be prolonged, the gas-bubble absorbing efficiency can be improved greatly, and the accuracy of the analysis result can be enhanced. Because the gas bubbles can generate outward force in the process of ascending lineally and can accumulate on the edge of a container, the spiral heaves of all circles are thinned at spiral intervals from the lower end to the upper end of the absorption tube. Because the spiral heaves of all circles are thinned at spiral intervals from the lower end to the upper end of the absorption tube, the speed of moving to the upper end of the absorption tube of the gas bubbles can be decreased, and the problem that the gas bubbles accumulate on the edge of the container can be solved.
Description
Technical field
The utility model relates to a kind of small-sized porous glass-tube absorption bottle, and particularly a kind of efficient small porous glass-tube absorption bottle that can effectively improve the exhaust emission collecting efficiency belongs to the environmental monitoring field.
Background technology
Atmosphere and exhaust emission (comprising gaseous contaminant, gasoloid etc.) monitoring all needs to draw the monitoring analysis result after sending lab analysis after spot sampling; And analysis result whether can accurately reflect the true pollution level of atmosphere quality true horizon and atmosphere pollution and spot sampling the time collecting efficiency of gaseous contaminant much relations are arranged, atmosphere and exhaust emission (as tens of kinds of pollutants such as SO2, NOX, O3, H2S) analytic process are mainly on-the-spot with after the absorption liquid collection at present, then send the laboratory by comparing quantitative from the typical curve of drawing afterwards with the standard solution analysis that contains serial different these materials of amount; And this quantitative prerequisite when being spot sampling the collecting efficiency of exhaust emission be 100% could be accurately, namely on-the-spot exhaust emission collecting efficiency is more high more can accurately reflect the atmospheric pollution level.
Present on-the-spot exhaust emission collecting efficiency does not reach 100%, nearly all standard method of analysis to this content all without identifying, all without concrete atmosphere and exhaust emission collecting efficiency data, some analytical approachs consider that the exhaust emission collecting efficiency may be on the low side and take simultaneously secondary to absorb and improved the exhaust emission collecting efficiency, and most of analytical approach remains one-level and absorbs.Therefore, present on-the-spot atmosphere and exhaust emission collecting efficiency are on the low side.The typical curve of most of GB analytical approachs is to get the standard substance that will carry out the quantitative test project to configure the standard solution of serial content after accurate quantitative analysis, draw out typical curve with the standard solution of serial content through lab analysis again, the absorption liquid that relatively gathers after atmosphere and exhaust emission is determined monitoring result; Typical curve is directly to come with the standard solution analysis that contains different amounts after accurate quantitative analysis, if coming the collecting efficiency of arbitrary concentration on the criterion curve by collecting efficiency is 100% certainly, it should be just wrong in theory that on-the-spot exhaust emission collecting efficiency does not reach 100%.Therefore, improving on-the-spot exhaust emission collecting efficiency is even more important to the accuracy that improves analysis result.
The spot sampling method of the regulations such as national standard analytical approach adopts the absorption tube (being also the general absorption tube of relevant industries basically at present) of regulation; Major part adds 10 milliliters to 50 milliliters of absorption liquids, and whole gaseous contaminant absorbs or the retardance process is bubble and is risen to by the absorption tube bottom and absorb the approximately bubble uphill process of 5 to 10 centimetres of left and right of liquid level.Such absorption process is difficult to reach 100% absorption efficiency.
