Description
Technical field
The present invention relates to a kind of multi-functional sampling gun of station boiler multitube, belong to gas sample field of measuring technique.
Background technology
During power boiler burning, in stove, burning is the important indicator of boiler implosion, produces in combustion in flue gas
The oxygen of life, carbon monoxide, carbon dioxide, nitrogen oxides, sulfur dioxide are all important Monitoring Data, particularly boiler efficiency
Smoke components accurately is sampled most important by calculating, the calculating of air preheater air leakage rate, discharge value.Simultaneously at the pressure of environmental protection
Under, energy-conserving and environment-protective increase day by day needs flue gas sampling device more accurately new today, and flue gas sampling device be it is also proposed by this
Higher requirement.At present flue gas in power station boiler sampling uses single regular length sampling steel pipe, and single steel pipe sampling is time-consuming takes
Labour and low precision and the data measured are the most representative, more can not meet the requirement of GB grid survey.
At present in the standard GB/T-10184-88 of China and industry standard all clear stipulaties, generating set back-end ductwork
Upper measurement smoke components must use gridding method layout measuring point to measure, and how to carry out gridding method synchro measure and carries sampling tube
Go out higher requirement.
Summary of the invention
It is an object of the invention to, in order to realize boiler of power plant square-section multi-pipeline synchronized sampling, again can be to single independence
Measuring point is individually sampled and multiple measuring points can also be carried out sampling functions in turn, and the open a kind of station boiler of the present invention is many
The multi-functional sampling gun of tubular type.
The technical scheme is that, a kind of multi-functional sampling gun of station boiler multitube, including sampling tube, retainer ring,
Also include thermocouple sheath, ladder base, the tee T of band control valve, control valve, mixed sampling pipe, blender and thermocouple temperature
Degree inserts handle；There are centre bore in circular ladder base central authorities, are evenly distributed with multiple same diameter on the circumference of centre bore
Sampling pore；Thermocouple sheath is arranged in the centre bore of ladder base, and the multiple sampling pores on ladder base are provided with not
The many sampling tubes with length；The rear portion of thermocouple sheath and sampling tube is fixed by ladder base, thermocouple sheath and sampling tube
Front portion by retainer ring, the sampling tube of thermocouple sheath is fixed；The rear end of sampling tube is equipped with the tee T of band control valve and control
Valve；The end, rear end of sampling tube is provided with blender；Mixed sampling pipe is installed on blender and electric thermo-couple temperature inserts handle；Thermoelectricity
Even temperature is inserted the tail end connecting thermocouple sheath.
Multiple slotted eye has uniformly been offered, the long axis direction of slotted eye on the radial direction casing wall of described thermocouple sheath
Radially consistent with thermocouple sheath.
Described thermocouple sheath, equipped with the equal thermocouple of same steel pipe quantity and length, can meet the same of smoke sampling simultaneously
Be connected with the external world by output lead slotting of Shi Jinhang temperature survey and every thermocouple.
Described mixed sampling pipe and blender are the gathering tubes of many sampling tubes, are aggregated into by the smoke components that every is sampled
In blender, blender communicates with every sampling tube but exports only one of which.
Described sampling tube is respectively arranged with the tee T of a band control valve after ladder base, and equipped with control before entering blender
Valve processed.
Described sampling gun can meet the demands of difference sampling according to test requirements document, can realize that multitube is sampled simultaneously, single tube takes
Sample or multitube carry out sampling requirement in turn, are i.e. regulated by three-way valve with mixed export bleeding point, can the most individually extract each pipe
Flue gas, it is achieved sample in turn.
The invention has the beneficial effects as follows, the present invention can sample by multitube simultaneously, and the control valve on every sampling tube cuts out and beaten
Drive the tee T of all band control valves thus to achieve multitube and externally lead directly to function, it is achieved that multitube simultaneously in flue to not
It is sampled with length sample point, grid survey requirement can be met；Optional single tube sampling, adopts according to sampling requirement is optional
Sample length of tube is sampled function to single-point.Also by blender, multitube is carried out sampling requirement in turn；All bands are controlled
The tee T of valve cuts out, and utilizes mixed sampling pipe and mixer functionalities, and operation control valve achieves many sampling tubes successively successively
The function of sampling, it is therefore prevented that single tube is taken out the phenomenon of group hourglass air and shortened the measurement time.
The thermocouple sheath of center drilling of the present invention, equipped with the equal thermocouple of same steel pipe quantity and length, can meet simultaneously
The temperature survey of smoke sampling.
The present invention can carry out the regulation of valve position by sampling gun multi-functional to multitube according to test requirements document before the test, meets test
In various requirement, can realize the flow measurement requirements such as multitube gridding method total cross-section also can meet single tube measure, meet simultaneously
Requirement synchronization that multitube is measured successively realize total cross-section temperature survey work.
