Description
Technical field
The utility model is related to biomass electric power plant measuring instrument technical field, and in particular to a kind of zirconium oxide measuring instrument is dust-proof
Device.
Background technology
In the combustion heating device such as boiler, its flue gas produced after burning is discharged through flue, in order to accurately grasp cigarette
The parameter of the smoke components in road, especially oxygen content, accurately to control the burning of boiler, generally adopts Zirconium oxide analyzer
Measure, which has and is swift in response, measurement range is wide, the advantages of long service life, thus obtain in gas-monitoring field
It is widely applied.
At present, a diameter of 30 μm of poroid mistakes are mounted on the domestic biomass electric power plant zirconia probe with chicken manure as fuel
Filter, is often directly protruding into exposed contact flue gas medium in flue, but due in flue flue-gas temperature typically at 850 DEG C
More than, and the standard operating temperature of zirconia probe is then at 750 DEG C or so, work of the flue-gas temperature far above zirconia probe
Temperature, makes zirconia probe be chronically in high-temperature flue gas, cause zirconia probe to be easily damaged, reduction of service life, reduction
The accuracy of measurement；On the other hand, as flue gas is excluded by flue, therefore the gas in environment to be measured is simply from the list of probe
Side inflow so that gas flow area is little, causes reference air be drawn into zirconia probe and produces potential, so as to cannot be accurate
Boiler oxygen content is measured really, and the detection efficiency so as to cause zirconia probe is low, while can also cause zirconia probe front end
Filter dust stratification, increased maintenance work, and the safe operation to boiler is unfavorable.
Content of the invention
The purpose of this utility model is for the deficiencies in the prior art, there is provided a kind of zirconium oxide measuring instrument is dust-proof
Device.
The technical scheme for realizing the utility model purpose is, a kind of zirconium oxide measuring instrument dust guard, and which includes dust cover
Body, described dust boot body one end pass perpendicularly through furnace wall and stretch in exhaust gases passes and be fixed on furnace wall, dust cover
Body stretches into the internal diameter of the length less than exhaust gases passes of exhaust gases passes, and the dust boot body stretches into the end of exhaust gases passes side
A blow vent is provided with, the dust boot body is provided with several otch, a zirconia probe away from exhaust gases passes air outlet side
It is located inside dust boot body.
Further, asbestos washer is cased between the dust boot body and furnace wall, for the leakage of water-proof fume-proof gas,
The antihunt action of dust cover can also be played simultaneously.
Further, the otch quantity is set to 1 ~ 3, is easy to flue gas free inside exhaust gases passes with dust cover
Circulation.
Further, the kerf width is set to 50 ~ 80mm length, to ensure that enough flue gases can enter into dust cover
Interior, reach the measurement request of zirconia probe.
Further, some otch are arranged at the one side of dust boot body, it is ensured that the essence of boiler oxygen content measurement
Accurate.
Further, the dust boot body is 316 stainless steel materials, to reach high temperature resistant, wear-resistant, corrosion resistant have
Beneficial effect.
The zirconium oxide measuring instrument dust guard that the utility model is provided, is made by being set with to be fixed on zirconia probe
With, very effective protective effect is played to whole zirconium oxide, the utility model is arranged in the front end of dust guard and lee face
For open mode, make when boiler smoke flows through zirconium oxide measuring instrument, flue gas can be free to enter in zirconia filters,
Probe is made to produce potential, so that it is guaranteed that boiler measurement of oxygen content is accurate, while not interfering with reference flue gas enters directly into oxygen
Change zirconium probe, decrease the bonded deposit of probe tip filter, reduce zirconic regular maintenance, prolong to a certain extent
The service life of zirconia probe is grown, guaranteeing role has been served to boiler safety stable operation.

Specific embodiment
Present pre-ferred embodiments are described in detail below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, a kind of zirconium oxide measuring instrument dust guard, which includes dust boot body 1, the dust cover
1 one end of body passes perpendicularly through furnace wall 2 and stretches in exhaust gases passes 3 and be fixed on furnace wall 2, and dust boot body 1 stretches into cigarette
Internal diameter S of length L of gas passage 3 less than exhaust gases passes 3, the dust boot body 1 stretch into the end 11 of 3 side of exhaust gases passes and set
There are a blow vent 110, the dust boot body 1 to be provided with several otch 12, an oxygen away from 31 side of air outlet of exhaust gases passes 3
Change zirconium probe 4 to be located inside dust boot body 1；Asbestos washer 5 is cased between the dust boot body 1 and furnace wall 2；Described cut
12 quantity of mouth are set to 1 ~ 3；12 width of the otch is set to 50 ~ 80mm length；Some otch 12 are arranged at dust cover sheet
The one side of body 1；The dust boot body 1 is 316 stainless steel materials.
During work, one end of zirconium oxide measuring instrument dust guard of the present utility model is extend into flue gas perpendicular to furnace wall
