Description
Technical Field
The utility model relates to the technical field of chemical or physical analysis, in particular to a wear-resistant and air leakage-proof zirconia oxygen analyzer.
Background
Zirconia is a ceramic, a solid with ion conducting properties. Monoclinic crystals at normal temperature, which change to cubic crystals when the temperature is raised to 1150 ℃, with a volume shrinkage of about 7%; when the temperature decreases, it becomes monoclinic again. The zirconia breaks when the heating and cooling are repeated. Thus, pure zirconia cannot be used as a measuring element. If a certain amount of calcium oxide or yttrium oxide is added to zirconia as a stabilizer, and then calcined at a high temperature, the zirconium oxide becomes a stable zirconia material, and at this time, tetravalent zirconium is replaced with divalent calcium or trivalent yttrium, and oxygen ion holes are generated, so that the zirconia belongs to an anionic solid electrolyte. Zirconia is mainly conductive by the movement of holes, and becomes a good oxygen ion conductor when the temperature reaches 600 ℃ or higher. When the oxygen partial pressure is different at both sides of the zirconia electrolyte, oxygen at the side with high oxygen partial pressure migrates to the side with low oxygen partial pressure in an ionic form, so that the platinum electrode at the side with high oxygen partial pressure loses electrons to display positive electricity, and the platinum electrode at the side with low oxygen partial pressure obtains electrons to display negative electricity, and thus oxygen concentration potential is generated between the two platinum electrodes. This potential is only related to the difference in oxygen content (oxygen concentration difference) in the gas on both sides at a certain temperature. If the oxygen content on one side is known (for example, the oxygen content in the air is constant), the oxygen content on the other side (for example, the oxygen content in the flue gas) can be expressed by using the oxygen concentration potential, and the oxygen concentration potential is measured to know the oxygen content in the flue gas.
The zirconia oxygen analyzer has the advantages of simple structure and sampling pretreatment system, high sensitivity and resolution, wide measuring range, high response speed and the like.
When the existing zirconia oxygen analyzer detects in a flue, an oxygen sensor is usually placed in a flue gas detection channel, and the oxygen sensor can touch the inner wall of the flue gas detection channel in the placing process, so that the surface of the oxygen sensor is damaged and worn, and in the detecting process of the oxygen sensor, the phenomenon of air leakage exists between a filter and the oxygen sensor along with the lengthening of the using time, so that the zirconia oxygen analyzer with wear resistance and air leakage prevention is provided.
