It is particularly important.Cost can be effectively reduced in the way of extraction sampling, install sampling pipe on original pipeline,
But junction is easy to appear loophole because of a variety of causes, while sample gas amount is unable to control, and sample gas temperature is excessively high,
It is easy damage monitoring device.And sample devices damage needs maintenance in time, but is not allow shutdown maintenance on important production line
, yield can be largely effected in this way, bring serious economic loss.Moreover, the furnace gas content analysis data of burner hearth are all band connection
Lock control, blowing out will be will lead to when monitor value is below or above a certain critical value, so needing to take feasible effective
Method reduces or eliminates analyzer exception bring production loss.Non-damageable sampling can be used continuously therefore, it is necessary to a kind of
Equipment.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of high-temperature furnace gas sample devices, have solved the prior art
The problem of sample gas temperature is excessively high, and collection capacity is not easy to control, and sampling pipe weld is easy leakage.
The technical solution of the utility model solution technical problem are as follows: a kind of high-temperature furnace gas sample devices, including sampling oblique cutting
Pipe 0, air shooter 1, high pressure gas delivery pipe 2, sampling inclining tube 0 are connected with 1 side wall of air shooter, sample inclining tube 0
With 1 angle of air shooter greater than 15 degree less than 50 degree, the rear portion and 2 front of high pressure gas delivery pipe of air shooter 1
It is connected, high pressure gas delivery pipe 2 is connected with calibrating gas storage tank, and sampling inclining tube 0 connect opening with air shooter 1 and is equipped with
Flapper 3,3 front of flapper are equipped with air pressure inside meter 14, and rear portion is equipped with shaft 17, and it is defeated that shaft 17 is mounted on sample gas
On the inner wall for sending pipeline 1, flapper 3 is connected with positive wirerope 6 and reversed wirerope 7, and it is defeated that positive wirerope 6 is pierced by gas
The side wall of pipe 1 and the shaft of positive capstan winch motor 4 is sent to be connected, 1 side wall of air shooter is equipped with the first seal box 8, positive capstan winch
Motor 4 is located in the first seal box 8, and reversed wirerope 7 is pierced by the side wall of sampling inclining tube 0 and the shaft of repercussion capstan winch motor 5
It is connected, the second seal box 9 is equipped on the left of sampling inclining tube 0 and 1 junction of air shooter, repercussion capstan winch motor 5 is located at second
In seal box 9.
The first barometer 12 is equipped in first seal box 8, the first seal box 8 is communicated with the outlet of the first atmospheric pressure compensating pump 10
Mouthful, the first atmospheric pressure compensating pumps 10 air inlets and is connected with calibrating gas storage tank；The second barometer 13 is equipped in second seal box 9, the
Two seal boxs 9 are communicated with the gas outlet of the second atmospheric pressure compensating pump 11, and the second atmospheric pressure compensating pumps 11 air inlets and is connected with calibrating gas
Storage tank.
Temperature monitoring 15 is equipped in air shooter 1, temperature monitoring 15 is equipped at least three, air shooter 1
Anterior posterior respectively has a temperature monitoring 15, sampling inclining tube 0 and 1 connector opposite air shooter 1 of air shooter
Inner wall is equipped with a temperature monitoring 15.
It samples and is equipped with third seal box 18 on the right side of inclining tube 0 and 1 junction of air shooter, third seal box 18 is equipped with
Third barometer 19.
High pressure gas delivery pipe 2 is equipped with water-cooled jacket 16.
Calibrating gas storage tank memory is placed with the calibrating gas for not influencing monitoring result.
The utility model has the beneficial effects that: sampling inclining tube 0 and 1 angle of air shooter are greater than 15 degree less than five
Ten degree can improve sampling efficiency to greatest extent, reduce the usage amount of calibrating gas.Due to 1 rear portion high pressure gas of air shooter
A large amount of high pressure gas can be passed through air shooter 1 by body delivery pipe 2, will form air-flow in air shooter 1, to keep sampling oblique
Gas in intubation 0 is inhaled into air shooter 1.
Flapper 3 can according to need adjustment angle, if full load produces, sample gas pressure in inclining tube 0
And temperature is excessive, it is necessary to it controls flapper 3 and is moved to closing direction, positive capstan winch motor 4 inverts appropriate circle number at this time,
Repercussion capstan winch motor 5 rotates forward appropriate circle number, just can control the reduction sampling inclining tube 0 of flapper 3 and enters in air shooter 1
Gas prevents monitoring device from overheating.It when small-scale production, then needs flapper 3 in an intermediate position, can not only allow in this way
Enter air shooter 1, the standard that will not also stop 1 rear portion of air shooter to pour in from sampling inclining tube 0 with Multi-example gas
High pressure gas.
First seal box 8 is the through hole in order to seal positive wirerope 6 on 1 side wall of air shooter, passes through first
Barometer 12 can monitor the air pressure in the first seal box 8 constantly, when air pressure is too low in the first seal box 8, it is necessary to pass through
First atmospheric pressure compensating pump 10 improves the air pressure in the first seal box 8, prevents gas to be detected from surprisingly leaking into the first seal box 8,
When the air pressure in the first seal box 8 is greater than the air pressure in air shooter 1, there will be no gas to be detected leakages, exist at this time
Gas can pour in air shooter 1 in the first seal box 8 under gas pressure, since gas is also standard in the first seal box 8
Gas, so will not influence monitoring result.
Second seal box 9 is other than playing the role of as the first seal box 8, moreover it is possible to prevent sampling inclining tube 0 and gas
The unexpected leakage of 1 junction of body delivery pipe can effectively prevent leakage by installing the second seal box 9.
Third seal box 18 can prevent sampling inclining tube 0 and the unexpected of 1 junction of air shooter from revealing, rule of thumb
It is small that probability is revealed at this position, so not having to installation gas compensation pump, it is only necessary to monitor third seal box by third barometer 19
Air pressure in 18 just illustrates that leakage leakage has occurred in junction once air pressure changes, but has the isolation of third seal box 18,
Leakage can be reprocessed during producing the free time.
Inclining tube 0 and about 1 two join domain of air shooter are sampled because of the reason of welding, there is no leakage can
Can, so without sealing.
Temperature monitoring 15 can play the role of monitoring temperature, cooperate water-cooled jacket 16, prevent from warm in air shooter 1
Height is spent, i.e., when the temperature is excessively high, accelerates 16 heat exchanger effectiveness of water-cooled jacket, reduction, which is passed through gas temperature, to cool down.
