Embodiment
Below, at first the utility model is made the general description, and interpretation.
A kind of high-temperature flue gas of the present utility model detects sampling system, comprising: mounting bracket, and filtrator 1, the sampling air flue contains the sensor 9 of detection probe, orders about the moving drive unit of sample air-flow, circuit; Described circuit comprises the robotization control circuit; Described sensor 9, its detection probe is arranged in the passage of sample air-flow warp; Described drive unit comprises: the gas jet device provides the air machinery of pressure gas.
Specifically: described air machinery comprises: pressurized air organization of supply YG, the first heating arrangements DYJRJG; The output terminal of pressurized air organization of supply YG is communicated with by the input end gas circuit of tracheae with the first heating arrangements DYJRJG; The output terminal of the first heating arrangements DYJRJG is communicated with by the input end gas circuit of tracheae with the jet nozzle 6 of gas jet device.
1. the front portion of sampling air flue is positioned at high-temperature flue, and its front end is provided with filtrator 1, to reach purposes such as the particle that filters in the flue gas, dust, prevents from thus to stop up or the like.In order to order about flow of flue gas, obtain required flue gas, drive unit has been installed, produce negative pressure thus, cause flue gas to become sample gas, in the sampling air flue, flow through the filtration of filtrator 1; And the detection probe of sensor 9 is arranged in the passage of sample air-flow warp, so just can onlinely obtain relevant instant high-temperature flue gas information.
2. the gas jet device has three ports usually: first port is the port that is provided with jet nozzle, and the right-hand member of jet nozzle inserts pressure gas and sprays towards a left side, offers through hole left small and right large in the jet nozzle, and the profile of its left part also is truncated cone left small and right large; Second port is the gas outlet, and it is in the front-left of jet nozzle, this port emergent gas, and gas outlet and nozzle are on same central axis; The 3rd port is positioned near the mouth mouth of jet nozzle, and it becomes vertical angle with central axis.
Pressure gas is after the mouth mouth of jet nozzle ejects, because pressure gas has obtained further compression in the process of jet nozzle inside of flowing through, so the gas that ejects from the mouth mouth has formed high velocity air, and forms negative pressure near the periphery of mouth mouth; Under the effect of this negative pressure, the 3rd the interior object gas (being sample gas) of port attracted endlessly, and with the gas mixing of high velocity air, finally in the lump from second port discharge.
3. the utility model people of present patent application, by gas jet device of the prior art is discovered, crystalline solid will take place and stops up in it after having used a stage, and crystalline solid stops up and often occurs in around the front end of jet nozzle.In addition, through dissecting research etc., further find, the sample gas that is attracted out in above-mentioned the 3rd port is high-temperature gas, there is the bigger temperature difference in the normal temperature compressed gas that this high-temperature gas and jet nozzle come out, this temperature difference causes the appearance of crystalline solid tamper, and big more, the easy more obstruction of the temperature difference; Otherwise more little being not easy more of the temperature difference results in blockage.Also have, comprise the gas jet device of jet nozzle, it and sample gas also exist the temperature difference, and the generation of this temperature difference and obstruction also exists positively related relation, and the promptly this temperature difference is big more, also be easy more the obstruction.
4. based on above-mentioned the 3rd understanding, fundamental starting point of the present utility model is to eliminate or to reduce the temperature difference.
5. in the superincumbent describe, in general terms, " output terminal of pressurized air organization of supply YG is communicated with by the input end gas circuit of tracheae with the first heating arrangements DYJRJG; The output terminal of the first heating arrangements DYJRJG is communicated with by the input end gas circuit of tracheae with the jet nozzle 6 of gas jet device "; so; the pressurized air gas that enters jet nozzle 6 is high-temperature gas; promptly: the sample gas gas that enters the pressurized air gas of jet nozzle 6, is attracted out from the 3rd port; the temperature difference of these two kinds of gases reduces greatly, stop up odds and obviously reduce thereby make obstruction avoid or make chocking-up degree to reduce greatly fully or make.
Further technical scheme 1.
Described drive unit comprises second heating arrangements; Second heating arrangements is adjacent with the gas jet device.
Illustrate that 1: the second heating arrangements produces heat, because adjacent, heat transferred causes the temperature of gas jet device to raise to the gas jet device, and it is eliminated or reduction with the temperature difference of sample gas, avoids stopping up.
Illustrate 2: overall technological scheme changes the pressure gas of input jet nozzle 6 into high temperature by normal temperature, adds the technical program the gas jet device is also heated, and so, prevents the better effects if of stopping up.
Further technical scheme 2.
Before describing this further technical scheme, earlier the situation of relevant blowback tracheae 7 in the prior art is done one and simply introduce.
The air machinery both jet nozzle in the gas jet device 6 provides pressure gas, orders about sample gas and flowed under the effect of negative pressure, air machinery also to blowback tracheae 7 pressure gas be provided, blow away particle on the filtrator 1, dust etc.; (exception is also arranged) in general, when jet nozzle 6 air feed, stop to blowback tracheae 7 air feed, otherwise, when blowback tracheae 7 air feed, stop to jet nozzle 6 air feed.Usually, in above-mentioned circulation change, in the by turns air feed that carries out that goes round and begins again, the time to jet nozzle 6 air feed during each is taken turns is relatively long, shorter relatively to the time of blowback tracheae 7 air feed.
More than the situation of relevant blowback tracheae 7 in the prior art has been done simple introduction.Below, to this further description of technical scheme do and introduction.
