The fields such as survey, heat treatment industrial furnace.
Wherein, Oxygen Measuring Instrument is also known as zirconia oxygen analyzer, it is mainly used for measuring flue gas in combustion process
Oxygen concentration can equally be well applied to the detection of Non-combusting gas oxygen concentration.The principle is as follows, the constant electrification of temperature in sensor
It learns battery and generates a millivolt potential, this potential can directly reflect the oxygen content concentration in flue gas.
Existing Oxygen Measuring Instrument mainly includes the groups such as oxygen probe, oxygen analyzer, calibrating gas pipe, wire barrel
At.It when needing to detect the oxygen content in high-temperature flue gas, needs for oxygen probe to be directly protruding into high-temperature flue gas, this zirconium oxide
Although oxygen analyzer reaction speed is fast, since oxygen probe is directly contacted with high-temperature flue gas, and often contain in high-temperature flue gas
There are a large amount of corrosivity dust impurities, oxygen probe is influenced by high temperature and corrosivity dust impurities simultaneously, and working life is big
The earth is reduced.
In consideration of it, a Oxygen Measuring Instrument resistant to high temperature of design, while the corrosivity powder in flue gas can be filtered
The Oxygen Measuring Instrument of dirt is urgent need currently on the market.
Utility model content
For present technology above shortcomings, can be filtered in flue gas the purpose of this utility model is to provide a kind of
Corrosivity dust impurities, and Oxygen Measuring Instrument resistant to high temperature.
To achieve the goals above, the utility model provides following technical solution:
A kind of High-temperature-reszirconium zirconium oxide oxygen analyzer, the High-temperature-reszirconium zirconium oxide oxygen analyzer include diversion pipe, pass through
Fixing pipe is inserted in the zirconia probe of diversion pipe rear end, the oxygen analyzer host being electrically connected with zirconia probe, described

Further, the ceramic filter is high-temp ceramic filter.
Further, described diversion pipe to be fixed in flue to be detected by the first mounting flange.
Further, the length of the diversion pipe is 200mm to 1200mm.
The beneficial effects of the utility model compared with the prior art lie in:
High-temperature-reszirconium zirconium oxide oxygen analyzer provided by the utility model is provided with diversion pipe, and diversion pipe front end is provided with
Ceramic filter, oxygen probe is not direct to be contacted with high-temperature flue gas, so that the High-temperature-reszirconium zirconium oxide oxygen analyzer of the utility model
It can be applied among high-temperature flue gas environment, while being provided with ceramic filter, by the corrosivity dust impurities in high-temperature flue gas
It is filtered, protects oxygen probe, so that the working life of oxygen probe greatly improves.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the High-temperature-reszirconium zirconium oxide oxygen analyzer of the utility model.
Specific embodiment
Below in conjunction with attached drawing, the High-temperature-reszirconium zirconium oxide oxygen analyzer of the utility model is described in detail.
It referring to Fig.1, is a kind of embodiment of the High-temperature-reszirconium zirconium oxide oxygen analyzer of the utility model, the high temperature oxidation resisting
Zirconium oxygen analyzer includes diversion pipe 8, the zirconia probe 6 and zirconium oxide for being inserted in by fixing pipe 48 rear end of diversion pipe
The oxygen analyzer host 1 of 6 electrical connection of probe, 8 front end of diversion pipe is provided with ceramic filter 9,8 outer wall of diversion pipe
It is provided with the first mounting flange 7 and the second mounting flange 5,4 outer wall of zirconia probe fixing pipe is provided with and described
The third mounting flange that two mounting flanges 5 match, the oxygen analyzer be provided with analog signal output, communication output, after
