Abstract
The utility model provides a waste gas absorption bottle adopting the kjeldahl method to detect protein. The waste gas absorption bottle adopting the kjeldahl method to detect protein comprises a bottle body (12), a waste gas air inlet pipe (14) and an air suction pipe (16), wherein the bottle body is provided with an accommodating chamber (10); the waste gas air inlet pipe is communicated with the accommodating chamber of the bottle body; the air suction pipe is arranged above the bottle body and communicated with the accommodating chamber; the waste gas air inlet pipe is communicated with the accommodating chamber via the side wall of the bottle body; the part in which the waste gas air inlet pipe is communicated with the accommodating chamber is near the bottom of the bottle body; one end, positioned inside the accommodating chamber, of the waste gas air inlet pipe is covered with a filter screen (15); a check valve (18) is arranged on a pipeline, positioned outside the accommodating chamber, of the waste gas air inlet pipe. According to the waste gas absorption bottle provided by the utility model, waste gas produced by the kjeldahl method to detect protein enters the accommodating chamber from the bottom of the bottle body, so that the waste gas can be sufficiently absorbed by alkaline liquid inside the accommodating chamber and the quantity of acidic gas entering a circulation water vacuum pump from the air suction pipe is effectively reduced.
Description
Technical field
The utility model relates to waste gas absorption bottle, is particularly applicable to the waste gas absorption bottle of Kjeldahl's method detection protein.
Background technology
Detect in the process of protein at Kjeldahl's method, the first step is operating as together hot digestion of sample, the concentrated sulfuric acid and catalyst, and protein is decomposed, and discharges SO simultaneously
2gas, SO
2gas has strong impulse.At present various are determined nitrogen checkout equipment and all will pass through pipeline, by the SO of discharge
2waste gas, by device for absorbing tail gas, then utilizes vacuum pump using circulatory water that waste gas is extracted out.Because the device for absorbing tail gas of existing use is to SO
2the absorption of gas is abundant not, makes part sour gas enter vacuum pump using circulatory water, greatly shortens the service life of vacuum pump using circulatory water.
Utility model content
The purpose of this utility model is to provide a kind of waste gas absorption bottle of Kjeldahl's method detection protein, and it can absorb SO fully
2gas, to reduce the pollution to environment.
The utility model provides a kind of Kjeldahl's method to detect the waste gas absorption bottle of protein, it comprises a bottle, an exhaust inlet pipe and an air intake duct, bottle has cavity volume, and the cavity volume of exhaust inlet pipe and bottle interlinks, and air intake duct is arranged at bottle top and communicates with cavity volume.Exhaust inlet pipe is communicated with cavity volume by the sidewall of bottle, and this part that communicates is near the bottom of bottle, and one end that exhaust inlet pipe is positioned at cavity volume is covered with a screen pack, and exhaust inlet pipe is positioned at and on the pipeline outside cavity volume, is provided with a check (non-return) valve.
Enter cavity volume because Kjeldahl's method detects the waste gas of protein from the bottom of bottle, therefore, waste gas can fully be absorbed by the liquid in cavity volume, has effectively reduced sour gas and has entered into the amount of vacuum pump using circulatory water from air intake duct.
Detect in a kind of exemplary embodiment of waste gas absorption bottle of protein at Kjeldahl's method, screen pack is 300 order to 600 eye mesh screens.
Brief description of the drawings
The following drawings only schematically illustrates and explains the utility model, does not limit scope of the present utility model.
Fig. 1 is a kind of exemplary embodiment that Kjeldahl's method detects the waste gas absorption bottle of protein.
Label declaration
10 cavity volumes
12 bottles
14 exhaust inlet pipes
15 screen packs
16 air intake ducts
18 check (non-return) valves.
Detailed description of the invention
For having more clearly, the technical characterictic to utility model, object and effect understand, now contrast brief description of the drawings detailed description of the invention of the present utility model, accompanying drawing is only for helping to understand the utility model, the not practical structures of representative products and true ratio, in each figure, identical label represents identical part.
In this article, " schematically " expression " is served as example, example or explanation ", any diagram, the embodiment that are described in this article " schematically " should be interpreted as a kind of preferred or have more the technical scheme of advantage.
As shown in Figure 1, Kjeldahl's method of the present utility model detects the waste gas absorption bottle of protein, comprises a bottle 12, exhaust inlet pipe 14 and an air intake duct 16.Bottle 12 has cavity volume 10, and exhaust inlet pipe 14 interlinks with the cavity volume 10 of bottle 12, and air intake duct 16 is arranged at bottle 12 tops and communicates with cavity volume 10.Exhaust inlet pipe 14 is communicated with cavity volume 10 by the sidewall of bottle 12, and this part bottom near bottle 12 that communicates, one end that exhaust inlet pipe 14 is positioned at cavity volume 10 is covered with a screen pack 15, and exhaust inlet pipe 14 is positioned at and on the pipeline outside cavity volume 10, is provided with a check (non-return) valve 18.
When use, the slaking apparatus blast pipe (not shown) that Kjeldahl's method detects protein is connected to exhaust inlet pipe 14, and digesting like this waste gas of discharging in blast pipe can enter in the cavity volume 10 of bottle 12 along the direction shown in solid arrow in figure.When use, in the cavity volume 10 of bottle 12, fill akaline liquid, the waste gas entering in cavity volume 10 is absorbed by akaline liquid.Because waste gas enters cavity volume from the bottom of bottle 12, therefore effectively increase the time of staying of waste gas in akaline liquid.
Check (non-return) valve 18 is arranged on the exhaust inlet pipe 14 outside cavity volume 10, flows out from exhaust inlet pipe 14 for the akaline liquid that prevents cavity volume 10.One end place that exhaust inlet pipe 14 is positioned at cavity volume 10 adds a screen pack 15, so that the waste gas air pocket in exhaust inlet pipe 14 enters into bottle 12 is become to minute bubbles, fully increase the contact area of waste gas and alkaline solution, waste gas is absorbed by akaline liquid more fully.Screen pack is selected 300 order to 600 object screen clothes, for example, be 400 eye mesh screens.Gas in cavity volume 10 can be discharged by the air intake duct 16 of bottle 12 tops along the direction shown in dotted arrow in figure.Can reach Kjeldahl's method by waste gas absorption bottle of the present utility model and detect the innoxious object of sour gas in the waste gas of protein, waste gas can fully absorb by the akaline liquid in cavity volume, effectively reduced sour gas and entered into the amount of vacuum pump using circulatory water from air intake duct.
Listed a series of detailed description is above only illustrating for feasibility embodiment of the present utility model; they are not in order to limit protection domain of the present utility model; allly do not depart from equivalent embodiment or the change that the utility model skill spirit is done; as the combination of feature, cut apart or repeat, within all should being included in protection domain of the present utility model.
