Description
Technical field
The present invention relates to a kind of optic probe anti-fouler measured for Geldart-D particle powder parameters.
Background technology
Geldart-D particle is a kind of effective ways of utilization air-flow conveying granular solid in the duct, is widely used in various
The powder conveying of industrial department, such as pipeline of the solid fuel in thermal power plant as coal dust.Geldart-D particle powder is joined
The accurate on-line measurement of number such as granularity, speed has great importance to ensureing production safety and improving production efficiency.In gas
In power conveying powder parameters measurement, existing measuring method includes sieve method, acoustic method, electrostatic method and optical method etc..Compared to
Other measuring methods, optical method has the advantages that intuitive measurement results, subsequent treatment are simple, measurement accuracy is high.However, there is also
One significantly the problem of --- band powder operation in the case of, fine powder particle easily pollutes optic probe, so that light
Learn probe to be difficult to obtain effective measurement signal, this turns into the commercial Application of limitation Geldart-D particle powder parameters measuring method
A bottleneck problem.At present, optic probe or dismounting light are directly changed typically after fine powder particle contamination optic probe
Learn probe and carry out manual cleanup.This scheme cost is higher, and is unfavorable for realizing the continuous on-line measurement of powder parameters.
To solve in Geldart-D particle powder parameters optical measurement process, subparticle pollutes optics in the pipeline of generally existing
The problem of probe, the present invention proposes a kind of optic probe anti-fouler measured for Geldart-D particle powder parameters, in band powder fortune
, still can be flexibly effectively antifouling to optic probe progress in the case of row, so as to make each optic probe in band powder operation
In the case of keep cleaning so that the commercial Application of Geldart-D particle powder parameters measuring method is possibly realized.
The content of the invention
It is an object of the invention to provide a kind of optic probe anti-fouler measured for Geldart-D particle powder parameters.For
The purpose of the present invention is realized, the present invention uses following technical scheme.
It is a kind of to include pedestal, optic probe, probe for the optic probe anti-fouler that Geldart-D particle powder parameters are measured
Wall, pipeline, pressure gauge and electric operator, it is characterised in that：The probe head wall is provided with air admission hole, the pedestal and is provided with
Electrically operated gate, the electrically operated gate can horizontally slip under the drive of electric operator in pedestal.
The air admission hole is connected with external compressed air, and air admission hole is uniformly distributed along probe head wall, to ensure uniform air inlet,
So as to form uniform air conservation layer on optic probe surface, prevent subparticle from polluting optic probe.
Sealing device is provided between the electrically operated gate and pedestal, to ensure the sealing of optic probe anti-fouler, so that
Outside preventing the powder in pipeline by gap leakage to pipeline.The electrically operated gate is square, and its length of side is more than the straight of optic probe
Footpath.
The pedestal, electrically operated gate are made by high-abrasive material, with the anti-wear performance of intensifier.
The pedestal be divided into above and below two parts, be connected by screw up and down between two parts, for be flexibly connected, to reach spirit
Dismounting living and the purpose for being convenient for changing parts.
Beneficial effects of the present invention：1）Can be antifouling to optic probe progress in the case of band powder operation, so as to ensure that
The real-time and accuracy of powder parameters measurement.2）Using compressed air and electrically operated gate double protection, the reliable of protection is enhanced
Property.
