Abstract
The utility model discloses a connected tube type gas detector tube belonging to the gas quick detecting device. The structures of the detector tube is that a glass tube is filled with two different kinds of indication powder for the gas measured; the indication powder is formed by the hybrid of the reactant and the carrier; the quartz sand, the silica-gel or the glass frit can be selected as the carrier; the scale indicating the concentration value of the gas measured is respectively labeled at the position of the outer wall of the glass tube relative to the position of two different kinds of indication powder. When the gas measured passes through the detector tube, the gas and the reactant react right away; the concentration value of the gas measured can be directly read out according to the discoloration length of the indication powder. The connected tube type gas detector tube can detect two different gases at the same time so as to make the gas detection be more convenient and quick and make the cost of the gas detection be low.
Description
The utility model belongs to the gas device for fast detecting.
The research work of gas device for fast detecting develops very fast at home and abroad, the existing at present fast detecting pipe that detects over one hundred kind of gas, for fast detecting toxic and harmful concentration provides a kind of means easily and effectively, domestic and international existing gas detecting tube can only detect single gas, for example, the CO gas detecting tube can only detect the concentration of CO gas; The NOx gas detecting tube can only detect gas concentration of NOx or the like.
The purpose of this utility model is to provide a kind of tubular gas detector tube, makes a gas detecting tube can detect the toxic and harmful of two kinds of coexistences simultaneously, thus reach make things convenient for, save time, purpose that cost is low.
The structural representation of connection tubular gas detector tube is seen accompanying drawing 1, connection tubular gas detector tube length is generally 17～19cm, the detector tube shell is made by the simple glass pipe, an end is equipped with sleeve pipe (5) in the glass tube, by its prop carrier, reactant and tamper etc., sleeve pipe is the glass tube of diameter less than outer tube.Carrier and reactant are determined according to the kind of tested gas.The selection of carrier is to be related to the variable color interface of indication powder in the detector tube and a key factor of gas flow rate and sensitivity, and carrier can be selected silica sand, zeyssatite, aluminium oxide, glass dust, ceramic powder, silica gel etc.The selection of reactant is the key that influences the every performance index of detector tube, and for example, when tested gas was CO, reactant was oleum and iodic anhydride, CO in the oleum medium with I
2O
5Redox reaction takes place, make indication powder (potpourri of carrier and reactant) become brown by white, draw the concentration of tested gas according to variable color length, carrier and reactant are filled in the glass tube after mixing evenly, the glass tube outer wall indicates the scale of the tested gas concentration of expression, and this scale is the concentration relationship curve of the detector tube variable color length of drawing according to standard substance and tested gas and is converted into scale and is printed on the outer wall of detector tube.
Because connection tubular gas detector tube can be measured two kinds of gas with various simultaneously, just need to fill two kinds of different indication powder simultaneously in the detector tube.Ground floor indication powder (depending on the indication powder of nearly sleeve pipe (5)) only makes the variable color of indication powder to a kind of chemically reactive in two kinds of tested gas, and the tested gas of another kind is not reacted, chemical reaction just takes place in this gas when only entering second layer indication powder.For example, major pollutants are carbon monoxide (CO) in motor vehicle exhaust emission, hydrocarbon (HC) and oxides of nitrogen (NOx), we make connection tubular gas detector tube with CO and HC, ground floor indication powder is a sulfuric acid, the potpourri of potassium dichromate and silica gel, second layer indication powder is an oleum, the potpourri of iodic anhydride and silica gel, when vehicle exhaust enters detector tube, at first through ground floor indication powder, at this moment HC reacts with indicating the reactant in the powder, make the indication powder become green by yellow, and any reaction does not take place in CO and ground floor indication powder, when having only through second layer indication powder, just react, make second layer indication powder become brown by white.Separate with tamper (4) between two kinds of indication powder, fill one section blank carrier in the front of tamper (4) (near the direction of sleeve pipe), length is approximately 4～6mm.Other two ends at the indication powder use tamper (2) and (3) to block respectively.Tamper can be selected bulked cotton, glass wool, polyacrylonitrile fibre etc., and its length is generally 3～4mm.
Description of drawings.Accompanying drawing 1 is connection tubular gas detector tube synoptic diagram, 1-detector tube shell among the figure; 2.3.4---tamper; 5---sleeve pipe; 6---ground floor indication powder; 7---blank carrier; 8---second layer indication powder; 9---the scale of indication concentration value.
Embodiment.Hydrocarbon that uses during a kind of measured automobiles exhaust emissions and carbon monoxide connection tubular type detector tube.The detector tube total length is 19cm, and the glass envelope internal diameter is 3.5mm, and the external diameter of sleeve pipe (5) is 3.2～3.4mm, and the ground floor indicator is measured HC concentration and used, and carrier is that (80～100 orders, specific surface are 300cm to silica gel
2/ g), reactant is sulfuric acid and potassium dichromate, and silica gel is evenly mixed with reactant, and ground floor indication powder total length is 6cm, it is long to reinstall blank silica gel 5mm, second layer indication powder is that the measure CO gas concentration is used, and carrier is still used above-mentioned silica gel, and reactant is oleum and iodic anhydride, silica gel is evenly mixed with reactant, second layer indication powder total length is 6cm, and between the two-layer indication powder and two ends are all blocked up with tamper, and tamper uses polyacrylonitrile fibre.The outer wall of glass tube is printed on scale, and this scale is that the concentration relationship curve of the detector tube variable color length of drawing respectively according to HC and CO reference material and tested gas is converted on the relevant position that scale is printed on ground floor and second layer indication powder outer wall respectively.
When detecting, open the detector tube two ends, make vehicle exhaust enter detector tube from the detector tube entrance point, 1.5 test finishes after minute, can read the concentration value of two kinds of gases, both saves time, cost is low again, and accuracy, precision etc. meets the detector tube request of national standard fully.
Claims (1)
