Description
Background technology
Gas sensor is the most important core component of gas analysis instrument, and expensive, service life is limited, gas
Body analytical instrument is waited when being detected, and mixed foreign gas can influence the service life of sensor inside gas.
Rich in a large amount of water vapours or there are high pressure gas in Industrial Stoves furnace gas, passed if entered according to the conventional method
Sensor, after moisture or high pressure gas in component reach analyzer, moisture is easily combined damage with organic matters such as some dust particles
Bad sensor, and high pressure gas is possible to cause the vibration membrane of gas sensor to be impacted and damaged.The two will be led
In-line analyzer is caused penalty or damage failure occur, analysis data are not allowed, and analysis of fumes is made to lose meaning.So as to make the whole series
Technique often parking maintenance, brings very big economic loss.
Technical field
The utility model is related to gas preprocessing technical field in coal chemical industry petrochemical production process more particularly to a kind of gases
The protective device of analyzer constant pressure and flow.
Utility model content
In view of this, the main purpose of the utility model is to provide a kind of protective device of gas analyzer constant pressure and flow.
Its technical solution is a kind of protective device of gas analyzer constant pressure and flow, it is characterised in that：Including
Water knockout drum, it is characterised in that：Sample gas port is detected at least provided with an air inlet and one on the water knockout drum, with
And the bottom of water knockout drum is provided with water knockout drum diversion pipe, which connects PU by the first spring pipe clamp and manages,
And including exhaust outlet, nozzle one and nozzle two are provided on the exhaust outlet, the PU pipes pass through second spring
Pipe clamp is connect with nozzle one, and the nozzle two is connect with detection sample gas port by fluorine rubber-pipe, is set on the fluorine rubber-pipe
There is sensor.
Further, the fluorine rubber-pipe passes through third spring pipe clamp respectively with nozzle two and the connecting pin of detection sample gas port
It is clamping fixed with the 4th bourdon tube.
Further, the first spring pipe clamp, second spring pipe clamp, third spring pipe clamp and the 4th spring pipe clamp are adopted
Use stainless steel.
Further, a diameter of 0.3mm of the blow vent of the sensor.
Above-mentioned technical proposal has following advantageous effects：
The utility model is provided with water knockout drum, and the water knockout drum is narrow and divide water knot based on the nozzle that leads to sensor air inlet
Structure, sample gas according to the flow and pressure of the controllable sample preparation gas of the metering function of pipeline, have very big limit herein by rear to it
Property processed, so as to effectively realize the purpose of control sample throughput and pressure, constant current constant voltage effect reaches original gas very
One of, it does not influence also to measure the accuracy of composition.For entire analyzer industry, the grade of product is improved, has reached height
Precision, high efficiency, the high desired effect protected.And the utility model additionally uses fluorine rubber-pipe when entering sensor, is situated between
In its stability, it not only ensure that sample gas degree of purity, but also the circulation conducive to sample gas, and corrosion-and high-temp-resistant, should not damage.It is whole
Stainless steel spring folder use, adequately avoid the leakage of sample gas, make measurement more accurate.

Specific embodiment
In order to which the object, technical solution and advantage for making the utility model patent are more clearly understood, below in conjunction with attached drawing and
The utility model patent is further elaborated in embodiment.It should be appreciated that specific embodiment described herein is only
To explain the utility model patent, it is not used to limit the utility model patent.
As described in Figure 1, the utility model provides a kind of protective device of gas analyzer constant pressure and flow, including water knockout drum
2, it is provided with point at least provided with an air inlet 1 and the bottom of a detection sample gas port and water knockout drum 2 on the water knockout drum 2
Hydrophone diversion pipe, the water knockout drum diversion pipe connect PU pipes 6 by the first spring pipe clamp 5,
And including exhaust outlet 7, nozzle one and nozzle two are provided on the exhaust outlet, the PU pipes 6 pass through the second bullet
Reed pipe folder 51 is connect with nozzle one, and the nozzle two is connect with detection sample gas port by fluorine rubber-pipe 4, in the fluorine rubber-pipe 4
On be provided with the sensor 3 of a diameter of 0.3mm of blow vent.
The fluorine rubber-pipe 4 passes through third spring pipe clamp 52 and the 4th respectively with nozzle two and the connecting pin of detection sample gas port
Spring pipe clamp 53 is fixed；The first spring pipe clamp, second spring pipe clamp, third spring pipe clamp and the 4th spring pipe clamp use
Stainless steel.
During its work, after sample gas enters the present apparatus by pipeline, by the air inlet of constant pressure and flow, into gas analyzer
The protective device of constant pressure and flow, sample gas is herein because water knockout drum is based on the nozzle for leading to sensor air inlet is narrow and bifurcation structure
Under the action of, since moisture is heavier, it is finally sunken to bottom under gravity, enters exhaust outlet through PU pipes, it is final to discharge；It is more
Remaining sample gas also directly reaches exhaust outlet by PU pipelines, and during this, a small amount of sample gas passes through in fluorine rubber-pipe, reaches sensing
Device achievees the purpose that detection.
It these are only the preferred embodiment of the utility model patent, be not intended to limit the utility model patent, it is all
All any modification, equivalent and improvement made within the spirit and principle of the utility model patent etc., should be included in this
Within the protection domain of utility model patent.
