Description
Technical field
The invention belongs to power domain, field of thermal power is especially belonged to, more particularly relates to be used for boiler
Ultrasonic liquid leveller and the boiler supporting with it.
Background technology
Boiler is a kind of energy conversion, and the energy inputted to boiler has chemical energy, electric energy in fuel, boiler output
Steam, high-temperature water or organic heat carrier with certain heat energy.The original meaning of pot refers to the water container heated on fire, and stove refers to burning
The place of fuel, boiler includes pot and stove two large divisions.The hot water or steam produced in boiler can directly be industrial production and people
The people's livelihood is lived provide needed for heat energy, can also be converted to mechanical energy by Steam Power Equipment, or by generator turn mechanical energy again
It is changed to electric energy.The boiler for providing hot water is referred to as hot-water boiler, is mainly used in also having a small amount of application in life, industrial production.Produce
The boiler of steam is referred to as steam boiler, is often simply called boiler, is used for thermal power station, ship, locomotive and industrial and mining enterprises.
The main operational principle of boiler is that the waste heat in the heat energy or industrial production discharged after a kind of utilization fuel combustion is passed
Pass the water in container, make water reach required for temperature or certain pressure steam heat power equipment.Boiler is in " pot " and " stove "
Two parts are carried out simultaneously, and water enters after boiler, and boiler heating surface feeds water the heat transfer of absorption in boiler circuit, makes water
The hot water or generation steam of certain temperature and pressure are heated into, application is brought out.In combustion apparatus part, fuel combustion is constantly put
Go out heat, the high-temperature flue gas produced that burns transfers heat to boiler heating surface by the propagation of heat, and self-temperature gradually drops
It is low, finally discharged by chimney.
In commercial Application, it is ensured that water level in the boiler has great importance in setting range, it is impossible to too low to cause pot
Stove dry combustion method, can not be too high, causes water-steam system in pot unbalance.Therefore, accurate, the timely water level in the boiler height that obtains is in industry
Have great importance in.
Ultrasonic liquid leveller uses newest technology of acoustic wave, the measurement accuracy of instrument is greatly improved, to interference echo
Have it is obvious must suppress function, with perfect liquid/thing position observing and controlling function.
But, due to the particularity of boiler water-steam system, after ultrasonic liquid leveller application in the boiler, often miss
Report, data reliability is extremely low.
The content of the invention
The present inventor has found that the major reason for producing ultrasonic liquid leveller wrong report is by substantial amounts of Germicidal efficacy
Substantial amounts of aqueous vapor rises in boiler use, and is condensed in the probe positions of ultrasonic liquid leveller, so that condensate is formed,
This condensate is captured by supersonic liquid level instrument probe, is takeed for water level and is had arrived at probe, therefore sends what water level was overflowed
Error signal.
How condensate is excluded to ultrasonic liquid leveller, the particularly influence to supersonic liquid level instrument probe, as ultrasound
Ripple tank gage applies the tackling key problem problem in boiler liquid level monitoring.
We are also contemplated that under conditions of condensate is excluded simultaneously, it is to avoid rainwater is flowed into boiler, the technology of this area
Personnel know that boiler is very high for the requirement of its reclaimed water, if rainwater penetrates into can not only cause damage to boiler, seriously
Possibility can also produce blast.
Based on this, the present invention to ultrasonic liquid leveller by being improved, by having additional a ultrasonic probe fixed mount,
Specifically, the ultrasonic liquid leveller disclosed by the invention for boiler, including ultrasonic probe, are connected with ultrasonic probe
Monitor, especially, has additional a ultrasonic probe fixed mount, the fixed mount includes in the present invention：
--- canopy, the canopy is umbrella lid, and its sophisticated place offers a through hole；
--- fixed pin, the canopy edge is to lower process and extends to form downward canned paragraph, the canned paragraph
Lower horizontal is bent, and forms card and section, and the canned paragraph is collectively forming fixed pin with card and section；
The ultrasonic probe is fixed in canopy, and its data wire is passed by through hole, is connected with monitor.
And as supporting equipment, a boiler is disclosed, including boiler body tank, the tank deck of body tank shrink to form cylinder
The fixing hole matched with card and section external diameter is additionally provided with the short neck of shape, the short neck.
In use, the card and section of fixed pin are matched with the fixing hole on boiler, ultrasonic probe is fixed on the upper of boiler
Side, and due to the effect of fixed pin, ultrasonic probe can be discharged apart from boiler certain distance, steam by this space, from
Without forming condensate at ultrasonic probe again.Meanwhile, canopy will cover at the top of whole boiler, prevent rainwater from entering.
Further, we are it is also preferred that the angle of card and section and canned paragraph is 110 ° ~ 130 °, so as to improve fixed
Stability, better ensures that stability, the validity of ultrasonic liquid leveller, particularly ultrasonic probe.
It is that on the basis of 110 ° ~ 130 °, we further disclose the card in the angle of foregoing card and section and canned paragraph
Raised up with the middle part of section, form semicircular rings.
And for this technical scheme, we accordingly have modified matched boiler structure, specially including pot
Furnace body tank, the tank deck of body tank shrink to form cylindric short neck, and the inwall level of the short neck forms mounting rod to inner process,
The top of the mounting rod is formed with the groove with circular rings diameter matches, also includes gag lever post, and the gag lever post is longer than logical
Well width.
In use, semicircular rings are passed through by groove, and with gag lever post by its spacing fixation, so as to realize supersonic liquid level
Fixation of the instrument particularly between ultrasonic probe and boiler, ultrasonic probe is apart from boiler certain distance, and steam can be by this
Space is discharged, so that condensate will not be formed at ultrasonic probe again.Meanwhile, canopy will cover at the top of whole boiler, prevent rain
Water enters.
After technical scheme disclosed in this invention, it has been found that the wrong report of ultrasonic liquid leveller is zero, and will be super
Sound wave liquid level instrument is used in after the liquid level monitoring of boiler, compared to the level monitoring mode of boiler in the prior art, more accurately and
When.
