Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clear, complete description.
In one embodiment, there is provided a kind of system for boiler smoke composition test, it is used to test cigarette in boiler flue 1
Gas composition, including：
Test pipeline, its two ends are respectively sampling end and analysis end；
Sampling end is provided with smoke sampling rifle 5, and one end is provided with the filtering probe 3 stretched into boiler flue；
Analysis end is provided with flue gas analyzer 12；
Sampling end and analysis end between be disposed with filter such as filter 7, except water assembly and supercharging device.
Filter is placed on most upstream, depth-type filtration can be carried out by the dust in flue gas, particle, to greatest extent
The blocking and abrasion to upstream device are reduced, to provide the measurement of clean safety except water assembly, supercharging device, flue gas analyzer
Condition；Before supercharging device will be placed in except water assembly, the water content in flue gas can be effectively reduced, reduce flue gas aqueous to downstream
The corrosion that supercharging equipment is caused (flue gas middle acid substance is dissolved in water, can be condensed in equipment surface and cause corrosion).
It is previously used in the system of boiler smoke composition test, is set between the smoke sampling rifle 5 and supercharging device
There is a pressure relief device such as relief valve 11.
Due to being condition of negative pressure inside flue, system drawing smoke needs to overcome larger resistance, typically configures larger work(
The supercharging device of rate, required suction is main to be provided by supercharging device such as Smoke pump 8 (flue gas analyzer generally also carries pump,
But the suction for providing is smaller), under this arrangement form, the exhaust gas volumn of flue gas pumping is larger, the cigarette that flue gas analyzer needs
Tolerance is smaller, and the two mismatch, will be many in superpressure so being provided with pressure relief device such as relief valve 11 before flue gas analyzer
Remaining flue gas drains into air, prevents from entering the excessive damage equipment of flow of flue gas analyzer.
It is previously used in the system of boiler smoke composition test, smoke sampling rifle 5 is fixed on boiler smoke by fixing device 4
On the flue wall 2 in road 1.
It is previously used in the system of boiler smoke composition test, smoke sampling rifle is fixed on flue wall 2 by fixing device 4
On on the thief hole that opens up.
It is previously used in the system of boiler smoke composition test, fixing device 4 is a taper cock body, and it has fixed flue gas
The through hole of sampling gun 5, material is elastomeric material.
It is previously used in the system of boiler smoke composition test, elastomeric material is heat resistant rubber.
The through hole is opened up in taper cock body center, by sampling gun insertion through hole, is goed deep into inside flue, usual cock body
Opening diameter be slightly less than sampling gun diameter, to prevent sampling gun from slipping, elastomeric material is, for example, heat resistant rubber, fills in thief hole
In after, outer wall and the thief hole of taper cock body agree with completely, seamless, can realize good sealing and fixed effect.
It is previously used in the system of boiler smoke composition test, except water assembly includes the water removal heat tracing pipeline 9 being sequentially connected
And water removal device 10.
It is previously used in the system of boiler smoke composition test, the material of filtering probe 3 is selected from porous ceramics or metal is close
Net.
It is previously used in the system of boiler smoke composition test, the surface of filtering probe 3 and smoke sampling rifle 5 is covered with one
Scuff-resistant coating.The scuff-resistant coating is abrasionproof coating or thermal treatment layer.
As described above, the smoke sampling rifle end of the application is provided with filtering probe, filtering probe carries out one-level to flue gas
Filtering, filtering probe can be right using materials such as the close nets of porous ceramics, metal, the features such as with anti-wear, corrosion-resistant, high temperature resistant
There is stronger adaptability in the smoke components test environment of boiler.Meanwhile, smoke sampling rifle and filtering probe carry out abrasionproof and add
Strength is managed, and the adaptability to test environment is further improved.
The application is provided with filter, and cascade filtration is carried out to boiler sampling flue gas, dust content is met flue gas point
The entrance requirement of analyzer, meets safe operating conditions.
The application is provided with smoke sampling rifle fixing device, and smoke sampling rifle is fixed, while testing position to boiler
Putting perforate has sealing function, prevents extraneous air from leaking into boiler from test perforate, influences the accuracy of test result.
The application is provided with Smoke pump, the resistance for overcoming boiler flue negative pressure and smoke components test system, by cigarette
Pneumatic transmission enters flue gas analyzer.Smoke pump does not have specific model specification requirement, and the suction requirement of pump is more than boiler flue negative pressure, survey
Amount SR and pressure sum needed for flue gas analyzer, consider further that certain nargin.
The application is provided with relief valve, for the flue gas of discharge test in time when flue gas analyzer is disabled, while preventing cigarette
Gas instantaneous delivery is excessive, protects the safe and stable operation of flue gas analyzer.Triple valve is changed to relief valve, flue gas is exceeded in pressure
Needed for composition measurement equipment during pressure, unnecessary flue gas is discharged automatically.
The application is provided with water removal device, to meet flue gas analyzer entrance as the requirement of dry flue gas, the water removal companion of setting
Pipe line be used for heat test flue gas, using electrically heat tracing mode, make flue-gas temperature be maintained at more than dew-point temperature (about 110~
120 DEG C), meet the job requirement of water removal device.Concrete principle is quickly removed water for condensation flue gas, by gas temperature position in water
Dew-point temperature water maintained above keeps the state of vapor before water removal device is entered, and prevents water from being condensed before water removal device is entered
In tube wall, unification is removed during vaporous water is sent into water removal device.Exert oneself and meet fume treatment.
In order to further illustrate progressive of the invention, illustrated with reference to engineering is actual.
Engineering construction example：
By taking denitration flue after a coal-fired plant boiler as an example, using traditional flue gas component measuring device, flue gas is generally comprised
The equipment such as sampling gun, sampling gun fixing device, flue gas analyzer, flue gas is passed directly into flue gas analyzer and is divided by sampling gun
Analysis is run by a period of time, situations below occurs：
1st, traditional measurement apparatus only install filter at sampling hammerhead, are not provided with substantially in system other positions
Filter device, and the flue gas dust burdening at boiler measuring point is often very high, only setting filter in pipette tips cannot meet filtering requirement,
Have a certain amount of ash and particle is flowed into downstream fume gas analyzer, analyzer is caused to damage.
2nd, traditional measurement apparatus set the independent filter beyond probe sometimes, but individually filter may
The ash that can be deposited, results in blockage to filter on the contrary.
3rd, traditional measurement apparatus rely only on the pump that flue gas analyzer carries and flue gas are aspirated, in flue negative pressure compared with
In the case of big, it is impossible to the offer suction force of stabilization.
And drawbacks described above can then be evaded using the detection means of above-described embodiment (the utility model) description.
Obviously, described embodiment is only a part of embodiment of the utility model, rather than whole embodiments.It is based on
Embodiment in the utility model, it is all that those of ordinary skill in the art are obtained under the premise of creative work is not made
Other embodiment, belongs to the scope of the utility model protection.
