Ball valve two on the by-pass line at end is set, gas filtering dryer is set between the ball valve one and sampling cabinet, by-pass line with
Sampling cabinet junction is hose connector, and sampling cabinet interior inlet end is provided with the air pump being connect with by-pass line, in sampling cabinet
Multiple gas monitoring instruments are provided with, transparent class visual window is set at the top of the sampling cabinet.
In said program, the ball valve one, ball valve two, air pump and gas monitoring instrument are connected with control system.
In said program, the gas monitoring instrument include H2S detector, ammonia monitor, sulfur dioxide monitor,
Oxycarbide monitor.
Through the above technical solutions, exhaust gas on-line period monitoring device provided by the utility model on gas transmission main pipeline simultaneously
Connection one section of by-pass line of setting, installs sampling cabinet on by-pass line.By air pump by the negative pressure exhaust gas in gas transmission main pipeline
It is extracted into by-pass line, enters in sampling cabinet after gas dry filter filters and dehumidifies.According to exhaust gas properties in sampling cabinet
The monitors such as hydrogen sulfide, ammonia are set, are monitored on-line to being drawn into the gas come.Set one respectively before and after sampling cabinet
A ball valve during if you need to overhaul or replace monitor or air pump, should close both sides valve.
By this on-line period device for monitoring and analyzing, there is following technical advantage：
1st, gas characteristic is improved so that the result that monitor transducer measures is more accurate.
2nd, can pretreatment component be installed additional before monitoring device according to the heterogeneity characteristic of gas, reduces exhaust gas to probe
Damage, extend the monitor service life.
3rd, babinet top is upper open type transparent class visual window, and Daily Round Check and repair is facilitated to replace.
4th, electric-control system can be installed concentratedly in sampling cabinet, be conveniently operated.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described.
Fig. 1 is a kind of exhaust gas on-line period monitoring device schematic diagram disclosed in the utility model embodiment.
In figure, 1, exhaust gas main pipeline；2nd, by-pass line；3rd, sampling cabinet；4th, ball valve one；5th, ball valve two；6th, gas filtration is done
Dry device；7th, hose connector；8th, air pump；9th, gas monitoring instrument；10th, transparent class visual window.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
The utility model provides a kind of exhaust gas on-line period monitoring device, as shown in Figure 1, the device includes and exhaust gas master
One section of by-pass line 2 that pipeline 1 is arranged in parallel is equipped with sampling cabinet 3, the side of the arrival end of sampling cabinet 3 on the by-pass line 2
It threads a pipe and ball valve 1 is set on 2, ball valve 25, ball valve 1 and sampling cabinet 3 are set on the by-pass line 2 of the port of export of sampling cabinet 3
Between gas filtering dryer 6 is set, by-pass line 2 and 3 junction of sampling cabinet are hose connector 7,3 interior inlet end of sampling cabinet
The air pump 8 being connect with by-pass line 2 is provided with, multiple gas monitoring instruments 9 are provided in sampling cabinet 3,3 top of sampling cabinet is set
