Description
Technical field
The utility model relates to a kind of primary air piping self-sealing tube socket samplers, belong to electric boiler smoke sampling technology neck
Domain.
Background technique
During power boiler burning, the size of unburned carbon in flue dust is the main indicator of coal-fired boiler in power plant efficiency of combustion
One of, unburned carbon in flue dust is the important referring to foundation of boiler combustion control efficiency in furnace, and the phosphorus content for controlling flying dust is to improve
The important means of boiler efficiency.First and second wind speed and primary air piping coal powder density how are effectively organized in combustion,
This just proposes the requirement of on-line measurement to survey crew.
Current existing station boiler is unit pulverized-coal system, and wind pressure is in 10kpa or more in coal pulverizer, because of measurement
The existing coal dust measurement means of many factors such as difficulty are all to install measuring point and equipment when coal pulverizer stops, and start coal-grinding
It is measured after machine normal operation, measurement finishes stopping coal pulverizer again and takes out measuring device, round-trip multi-pass operation pair
Unit load is affected, frequent operation brings unfavorable factor to equipment and operational safety simultaneously.
Summary of the invention
The purpose of this utility model is to measure problem, this reality according to existing for existing station boiler unit pulverized-coal system
With novel, a kind of primary air piping self-sealing tube socket sampler is disclosed.
Technical solution of the utility model is as follows, a kind of primary air piping self-sealing tube socket sampler, including ball valve,
Seal pipe, sampling pedestal, drive pipe seat, sampling hole nut and sealing nut.The drive pipe seat is mounted on sampling pedestal
Among, sampling hole nut is mounted on the sample tap of drive pipe seat；Seal pipe is vertically mounted on sampling chassis side, with sampling
Base intracavity connection；Ball valve is mounted in the middle part of seal pipe；It seals tube end and is equipped with sealing nut.
The sampling pedestal is the basis of entire sampling equipment, open loop connected in star provides channel to compressed air in it, is used
Enter in annular groove in the compressed air of sealing by sealing pipeline and air seal is carried out for sampling equipment by annular cone mouth；
The sampling pedestal is columnar structured, interior open loop connected in star；Annular groove upper port is equipped with internal screw thread, under annular groove
Portion is annular cone mouth；The sampling base side wall aperture, connect with seal pipe；Annular groove provides channel for compressed air.
Collar extension has a screw thread in the drive pipe seat, and external screw thread is connected with sampling pedestal, and to be combined into compressed air air inlet close
Seal channel；Drive pipe seat internal screw thread is connected with sampling hole nut.External screw thread with sampling pedestal be connected be combined into compressed air into
Hermetic seal channel provides sealing function for entire sampling equipment, and drive pipe seat internal screw thread is connected with sampling hole nut, for sampling
Nut is provided, the effect of being fixedly linked is provided.
The sampling hole nut is a common threaded nut and is connected with drive pipe seat screw thread that diameter, which is slightly larger than, to be taken
Sample rifle, back out nut can will sampling gun be inserted into coal pipe in be sampled.
The concrete operations of the utility model sampler are as follows: sampling when pulverized coal preparation system operates normally under not sampling state
Pedestal, drive pipe seat, the closely coupled ball valve in one, seal pipe of sampling hole nut three's screw thread be in close state,
And the nut of tail portion is tightened, entire sampler does not leak tightly.First the nut of seal pipe tail portion is unscrewed and connected when such as sampling
Compressed air slowly opens ball valve after confirmation ventilation and carries out ventilation sealing to sampler.Because compressed air pressure is far longer than
Pulverized coal preparation system pressure, and opposite guiding air-flow, pole are formed in the annular cone mouth groove of sampling pedestal and drive pipe seat composition
Operating pressure in pulverized coal preparation system can be pressed against to form a gas curtain by a small amount of high-head compressed air completely, and minimal amount of
Compressed air will not generate any influence to primary wind pipe wind speed.It unscrews sampling hole cap and sealing pressure is adjusted by seal ball-valve
Compressed air sealing pressure is adjusted to until system do not leak outside just by power.Operating pressure is 10- in pulverized coal preparation system normal pipeline
13kpa or so, sampling hole cap unscrew pulverized coal preparation system under state and are connected with the external world, and the empty gas formed is compressed in annular cone mouth groove
Under curtain sealing, external and internal pressure reaches balance at sampling hole.
The utility model has the beneficial effects that the structure of the utility model sampler is simple, it is easily installed operation；This reality
Pipeline external and internal pressure is effectively reached into balance convenient for testing crew on-line operation with New Energy；The utility model have it is good
Linear sealing performance not will cause running coal dust leakage, can prevent the pollution of the environment, mitigates cleanup crew's workload, while
Beautiful work-yard.
Detailed description of the invention
Fig. 1 is a kind of primary air piping self-sealing tube socket sampler schematic diagram；Fig. 2 is the top view of Fig. 1；
In figure, 1 is sampling hole nut；2 be drive pipe seat；3 be sampling pedestal；4 be seal pipe；5 be ball valve；6 be close
Seal nut.
Specific embodiment
Specific embodiment of the present utility model is as depicted in figs. 1 and 2.
The present embodiment is achieved like this, a kind of primary air piping self-sealing tube socket sampler of the present embodiment, including is taken
