Description
Technical field
A kind of online de-watering apparatus of water quality volatile organic matter of the utility model, belongs to environment protection field, and in particular to water body
Volatile organic matter on-line monitoring.
Background technique
The key instrument that existing qualitative, quantitative measurement volatile organic matter uses is gas chromatograph, is mainly used in flue gas
Or the on-line monitoring field of atmospheric volatile organic compounds, in order to guarantee the stability of chromatographic apparatus, analyzed gas enters color
It is pre-processed before spectrometer, mainly gas removes water link.The water removal of existing flue gas system mainly using condensation water removal or
Desiccant directly removes water, these method systems are not only complicated, maintenance is larger, but also will cause in treatment process to object gas
Loss and interference, the accuracy of final impact analysis.
Utility model content
The utility model overcomes the shortcomings of the prior art, provides a kind of water quality volatile organic matter and removes water online
Device, solves the problems, such as existing water removal link to the interference of target substance and the loss of target substance, and system is simple, daily dimension
Shield amount is small.
In order to solve the above-mentioned technical problem, a kind of the technical solution adopted in the utility model are as follows: water quality volatile organic matter
Online de-watering apparatus, including nafion pipe, hydrogen sky all-in-one machine, sample gas inlet end and sample gas outlet side, the one of the nafion pipe
End is connected to sample gas inlet end, and the other end of the nafion pipe is connected to sample gas outlet side, and the sample gas inlet end and sample
Gas outlet side is connected to by the film inner channel of nafion pipe, and film outer passage one end of the nafion pipe is emptying end, institute
The film outer passage other end for stating nafion pipe is connected on hydrogen sky all-in-one machine by drying pipeline, is arranged on the drying pipeline
There is the drying chamber of filling desiccant, using the barometric gradient of outside moisture in the film of nafion pipe by the dehydration in sample gas.
Flow valve and solenoid valve are provided on the drying pipeline.
The utility model has the beneficial effect that the utility model compared with prior art in order to solve water removal link pair
The interference and loss of target substance, using the moisture removed based on the chemical affinity of nafion thiosulfonic acid in gas, in this way
Object gas will not with contact with moisture and cause to be lost, and nafion tubing matter will not to object gas formed interfere.Due to
The water removal of nafion pipe needs to form the barometric gradient of moisture in nafion film two sides, and the utility model acquires surrounding by compressor
Surrounding air, it is right on the outside of nafion film by the movement that PLC controls solenoid valve to be sent to dry air after desiccant dryness
Target substance carries out continual water removal.This method can guarantee water removal effect and due to water removal mode be it is contactless,
Also eliminate the interference problem to target substance.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1 be nafion pipe, 2 be hydrogen sky all-in-one machine, 3 be sample gas inlet end, 4 be sample gas outlet side, 5 be emptying end,
6 it is drying pipeline, 7 be drying chamber, 8 be flow valve, 9 is solenoid valve.
Specific embodiment
As shown in Figure 1, a kind of online de-watering apparatus of water quality volatile organic matter of the utility model, including nafion pipe 1, hydrogen
One end of empty all-in-one machine 2, sample gas inlet end 3 and sample gas outlet side 4, the nafion pipe 1 is connected to sample gas inlet end 3, described
The other end of nafion pipe 1 is connected to sample gas outlet side 4, and the sample gas inlet end 3 and sample gas outlet side 4 are managed by nafion
1 film inner channel connection, film outer passage one end of the nafion pipe 1 is to empty end 5, outside the film of the nafion pipe 1
The wing passage other end is connected on hydrogen sky all-in-one machine 2 by drying pipeline 6, is provided with filling desiccant on the drying pipeline 6
Drying chamber 7, using the barometric gradient of outside moisture in the film of nafion pipe 1 by the dehydration in sample gas.
Flow valve 8 and solenoid valve 9 are provided on the drying pipeline 6.
The utility model is in order to solve interference and loss of the water removal link to target substance, using based on nafion thiosulfonic acid
Chemical affinity remove the moisture in gas, such object gas will not cause to be lost with contact with moisture, and nafion
Tubing matter will not form object gas and interfere.Since the water removal of nafion pipe needs to form the pressure of moisture in nafion film two sides
Gradient, the utility model acquire ambient air by compressor, control solenoid valve by PLC after desiccant dryness
Dry air is sent on the outside of nafion film and carries out continual water removal to target substance by movement.This method can guarantee to remove water
Effect and due to water removal mode be it is contactless, also eliminate the interference problem to target substance.
The utility model is explained in detail above in conjunction with embodiment, but the utility model is not limited to above-mentioned implementation
Example, within the knowledge of a person skilled in the art, can also be in the premise for not departing from the utility model aims
It is lower that various changes can be made.
