Abstract
The utility model provides an improved zircite concentration cell type oxygen detector. Besides the key components of a zircite element and a casing of the detector, a ceramic protecting tube is additionally arranged outside the casing of the detector, and a high-temperature cotton filtering net is additionally arranged in front of the zircite element. Thereby, the service life of the oxygen detector is prolonged, the accuracy is improved and the maintenance quantity is decreased.
Description
Affiliated technical field
The utility model relates to the surveying instrument of oxygen in a kind of industrial gasses.
Background technology
Zirconia concentration cell type oxygen analyser is widely used in the online detection of atmosphere oxygen level in the industries such as electric power, metallurgy, petrochemical complex in the industry.Have continuous, sensitive, simple in structure, use, advantage such as easy to maintenance, particularly can under hot environment, carry out continuous coverage, especially other measuring method can not compare.Whole instrument is made up of two parts: the converter of detecting device of promptly measuring and support sensors work and demonstration measurement result is formed.As the detecting device that directly contacts with measured medium is the key that influences measurement result and serviceable life.
Summary of the invention
Because detecting device and zirconia component are in high temperature, the work down of high dirt environment for a long time.The flow at high speed of the contained dust of tested gas enters the distortion that zirconia component all can cause measurement result to the wearing and tearing and the dust of detecting device, even failure.
The purpose of this utility model is 1: install a ceramic protecting pipe outside the detecting device housing additional.Its effect is the wearing and tearing that prevent the detecting device housing, to prolong detecting device serviceable life.2: precedingly install measuring error that the cotton screen pack of high temperature causes to prevent dust from entering detecting element additional at detecting element (tubular zirconium-oxide), reduce maintenance.
The technical solution of the utility model is as follows: 1, a kind of zirconia concentration cell tye detector is made up of ceramic protecting pipe, the cotton screen pack of high temperature, zirconia component, detecting device housing and converter.It is characterized in that outside detecting housing, installing a dismountable ceramic protecting pipe additional.2, before tubular zirconium-oxide, install the cotton screen pack of high temperature additional.
The measuring object of zirconia oxygen analyzer is the combustion tail gas of various Industrial Stoves, and most mounting points is all answered technological requirement and is installed in before the dust arrester.The flow at high speed of the very big flue gas in addition of the content of dust is quite severe to the wearing and tearing of detecting device in the flue gas like this, particularly the low value coal more has a large amount of dust even the generation of incombustible particle.Be to cause the main cause of measuring failure concerning traditional wear problem with the oxygen detector of stainless steel making like this.And adopt special material and the abrasionproof of stainless steel surfaces handled cost higher.The utility model is to install a dismountable ceramic pipe additional outside the detecting device housing, utilize the low and ceramic pipe of connection, cost between high-temperature flexible inserts transition pottery and the metal for convenience detachly repeatedly to use.Reach the purpose that reduces use cost.2 for preventing that dust from entering measuring sensor (tubular zirconium-oxide) and installing the cotton screen pack of high temperature additional before the zirconium pipe flange.Be characterized in that good heat-resistant and flocculent structure play good filtration, particularly metal and ceramic fine dusts of adhering to easily had good filtration.Can significantly reduce maintenance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is vertical section structure figure of the present utility model.
The cotton screen pack of 1. high temperature among the figure, 2. zirconium pipe mounting flange, 3. tubular zirconium-oxide, 4. flexible inserts, 5. set collar, 6. ceramic protecting pipe, 7. detecting device housing.
Embodiment
Present embodiment is to increase the cotton screen pack (1) of a high temperature in zirconium pipe mounting flange (2) front, and ceramic protecting pipe (6) is fixed on the detecting device housing (7) with set collar (5).And between set collar (5) and ceramic protecting pipe (6), fill with flexible inserts (4).
Claims (3)
1, a kind of zirconia concentration cell tye detector is made up of zirconia component, detecting device housing and wear-resistant protection tube, it is characterized in that increasing a ceramic wear-resistant protection tube and install the cotton screen pack of a high temperature additional before tubular zirconium-oxide.
2, zirconia concentration cell tye detector as claimed in claim 1 is characterized in that installing additional a ceramic wear-resistant protection tube outside the detecting device housing.
3, zirconia concentration cell tye detector as claimed in claim 1 is characterized in that installing additional the cotton screen pack of a high temperature before tubular zirconium-oxide.
