Abstract
The utility model discloses a formaldehyde detecting box which can be used for rapidly detecting formaldehyde gas contents and distinguishing the harmful gas degrees through the change of medicament colors. Two transparent tubes which are respectively provided with liquified phenol reagent and diatomite powder medicament are used as reagent reaction beds; a closed vacuum container is used as a pre-power automatic sampling device; the vacuum container is connected the transparent tube which is provided with the diatomite powder medicament by a slim tube; the two transparent tubes are connected with each other by the slim tube to make formaldehyde liquid enter the transparent tube which is provided with the liquified phenol reagent following air; the formaldehyde liquid passes through the slim tube and finally reach the bottom of the transparent tube which is provided with the diatomite powder to react with the powder medicament; a definite color is displayed; the color is compared with the attached color comparison card to determine the concentration of formaldehyde in the air. The utility model has the advantages of simple structure and low cost.
Description
Technical field
The utility model relates to a kind of harmful gas pick-up unit, but the automatic detection box of fast measuring content of formaldehyde gas especially.
Background technology
Along with the rise of house decoration, a large amount of uses of finishing material must cause the pollution of room air, and formaldehyde is exactly a kind of in the harmful gas.At present, the method for formaldehyde gas is generally used the large-scale instrument analysis in the conventional sense air.This large-scale instrument, the detection sensitivity height, quantitatively accurately, strong interference immunity, but testing expense height, cycle are long, need the professional to operate, and are difficult to popularize.Therefore be necessary to develop a kind of simple, rapidly, reliable, formaldehyde gas pick-up unit that expense is lower, make people more acceptant.
Summary of the invention
Technical problem to be solved in the utility model provides the content that can detect formaldehyde gas in the air at short notice automatically that a kind of method is simple, expense is cheap, with the formaldehyde gas detection box of color identifying harmful gas degree.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of formaldehyde gas detects box, comprise vacuum tank, transparent tube, tubule, sealing-plug, colorimetric card, the vacuum tank that has sealing-plug is communicated with by the end of tubule with the transparent tube that diatomite powder is housed that has sealing-plug, the other end of transparent tube has the end that sealing-plug is equipped with the transparent tube of liquefied phenol reagent and is communicated with other one by tubule, and the other end that the transparent tube of liquified phenol reagent is housed is equipped with sealing-plug.
The volume of described vacuum tank is 50～500 milliliters.
The diameter of described transparent tube is 1～10 millimeter.
The diameter of described tubule is less than the diameter of transparent tube.
The shape and the volume of described two transparent tube are identical.
Described transparent tube is glass or transparent plastic material.
The beneficial effects of the utility model are: can measure the safe concentration of formaldehyde gas quickly and easily, method is simple, reliable results, and expense is cheap.
Description of drawings
Fig. 1 is that formaldehyde gas of the present utility model detects box user mode figure.
Embodiment
Below in conjunction with accompanying drawing and example the utility model is further specified:
As shown in Figure 1, formaldehyde gas detects two shapes, the identical diameter of volume are housed in the box is 3 millimeters glass tube 2,3, a glass tube 3 is equipped with liquified phenol reagent, another glass tube 2 is equipped with the diatomite powder medicament, as the reagent reacting bed, two of every glass tube is respectively with rubber stopper 7,8,9,10 sealings; 100 milliliters enclosed vacuum container 1 usefulness rubber stopper 6 sealings; Also having two diameters in addition is 1 millimeter tubule.
During use, select a certain place of family to test, close the doors and windows, room air is remained static, test better effects if in 1 meter eminence overhead.
With diameter is that 1 millimeter tubule 5 one ends insert in the rubber stopper 9 on the glass tube 3, contact with liquified phenol reagent, in the rubber stopper 8 on the other end insertion glass tube 2, contacts with the diatomite powder medicament.Be that 1 millimeter tubule 4 inserts in the rubber stopper 7 on the glass tubes 2 again with diameter, the other end inserts in the rubber stopper 6 of vacuum tank 1, choose rubber stopper 10 on the glass tube 3, formaldehyde gas enters glass tube 3 with air, be adsorbed in the liquified phenol reagent, because the effect of negative pressure flows in the glass tube 2 by tubule 5 liquid preparations, reacts with the diatomite powder medicament.Observe the diatomite powder change in color, after 15 minutes, color in the glass tube 2 and subsidiary colorimetric card contrasted, see whether exceed standard and concentration of formaldehyde how.
Described vacuum tank can be rectangular parallelepiped, square, round vase or other shapes.Glass tube can replace with lucite pipe.
For easy to carry, can do an interlayer at the outer wall of vacuum tank, transparent tube, tubule, the colorimetric card of sealing are put into wherein, be convenient to sell and use.
Claims (6)
1, a kind of formaldehyde gas detects box, comprise vacuum tank, transparent tube, tubule, sealing-plug, colorimetric card, the vacuum tank (1) that it is characterized in that having sealing-plug (6) is communicated with by the end of tubule (4) with the transparent tube that diatomite powder is housed (2) that has sealing-plug (7), (8), the other end of transparent tube (2) is communicated with by the end of tubule (5) with the transparent tube that liquified phenol reagent is housed (3) that has sealing-plug (9), (10), and the other end of the transparent tube of liquified phenol reagent (3) has sealing-plug (10).
2, formaldehyde gas according to claim 1 detects box, and the volume that it is characterized in that described vacuum tank (1) is 50～500 milliliters.
