Description
Technical field
The utility model relates to density sampling and measures, and is specifically related to the sampler of differential density meter.
Background technology
The desulfuration absorbing tower slurries of current a big chunk thermal power plant are measured and are adopted differential density meter, one section of sampling pipe is respectively welded in absorbing tower wall top and the bottom, pipe centerline and vertical direction angle are 45 degree, and sampling pipe is provided with Hand-operated butterfly valve, for isolating differential density meter.Because the inner slurries in absorption tower have a large amount of bubble, when differential density meter puts into operation, positive/negative-pressure side sampling pipe all can gassy and reach equilibrium state, is then converted into density value according to the differential pressure signal measuring gained.The maximum advantage of this metering system is the problem solving density measure line clogging, and there is not measuring unit abrasion condition, but in practical engineering application, densitometer sampling pipe often occurs that pneumatosis too much causes positive/negative-pressure side to measure pipeline and there is pneumatosis imbalance, the differential pressure value recorded deviate from actual value, this situation just can will be recovered by exhaust, has both added the reliability that maintenance workload again reduces equipment.
Therefore, there is the unbalanced problem of pneumatosis in the sampling apparatus of current differential density meter.
Utility model content
Technical problem to be solved in the utility model is that the sampling apparatus of current differential density meter exists the unbalanced problem of pneumatosis.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts there is provided a kind of sampler of differential density meter, the sampler of differential density meter, the upper and lower of tested tower body is respectively equipped with two sampling pipes, sampling pipe described in two projects coincidence in the horizontal plane, described sampling pipe is inclined upwardly, described sampling pipe comprises intermediate conduit and about symmetrically arranged two by-paths of described intermediate conduit, described intermediate conduit, each air intake opening of described by-path be centrally located in same level, the gas outlet of by-path described in two is incorporated to described intermediate conduit and forms remittance gas port, the outer end of described remittance gas port is provided with butterfly valve, the gas outlet of described intermediate conduit is gas production mouth.
In the sampler of above-mentioned differential density meter, described gas production mouth is provided with flange.
In the sampler of above-mentioned differential density meter, described sampling pipe is horizontal by 45 ° of angles.
In the sampler of above-mentioned differential density meter, described butterfly valve is Hand-operated butterfly valve.
In the sampler of above-mentioned differential density meter, the angle of described by-path and described intermediate conduit is 60 °.
Sampling pipe of the present utility model is welded by intermediate conduit, two by-paths, forms multidraw, these three mutual UNICOMs of pipeline, finally converges into a road for the sampling of differential density meter.The gas production mouth being in two sampling pipes of tested tower body upper and lower is all inclined upwardly, in three sampling spots, the pipeline of any point occurs that pneumatosis makes internal pressure rise, the gas of equivalent will automatically be discharged by other two pipelines be squeezed, automatically pressure compensation is carried out, so just overcome the problem that sampling pipe accumulates too much gas, smart structural design, structural mechanics and pneumodynamics are combined, solve the difficulty occurring the necessary manual exhaust of pneumatosis, also overcome the defect that differential pressure measurement is inaccurate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model provides a kind of sampler of differential density meter, smart structural design, automatically can carry out pressure compensation, overcomes the problem that sampling pipe accumulates too much gas.Below in conjunction with specific embodiment and Figure of description, the utility model is described in detail.
As shown in Figure 1, the utility model provides a kind of sampler of differential density meter, comprises the sampler of differential density meter, and the upper and lower of tested tower body 1 is respectively equipped with the projection in the horizontal plane of two sampling pipes 2, two sampling pipe 2 and overlaps.
Sampling pipe 2 is inclined upwardly, sampling pipe 2 comprises intermediate conduit 21 and about symmetrically arranged two by-paths 22 of intermediate conduit 21, each air intake opening of intermediate conduit 21, by-path 22 be centrally located in same level, the gas outlet of two by-paths 22 is incorporated to intermediate conduit 21 and forms remittance gas port, the outer end of remittance gas port is provided with butterfly valve 23, and the gas outlet of intermediate conduit 21 is gas production mouth 24.
Gas production mouth 24 is provided with flange, is convenient to be connected with differential density meter 3.Sampling pipe 2, horizontal by 45 ° of angles, is convenient to gas and is automatically upwards discharged sampling.
Butterfly valve 23 is Hand-operated butterfly valve, can manual control sample time and frequency, and living alone property is high.
By-path 22 is 60 ° with the angle of intermediate conduit 21, the interval of the air intake opening of by-path 22 and the air intake opening of intermediate conduit 21 is larger, then auto-compensation effect is better, but need the structural stability considering sampling pipe 2 entirety, therefore by-path 22 and the angle of intermediate conduit 21 are set to 60 ° by the present embodiment simultaneously.
Sampling pipe of the present utility model is welded by intermediate conduit, two by-paths, forms multidraw, these three mutual UNICOMs of pipeline, finally converges into a road for the sampling of differential density meter.The gas production mouth being in two sampling pipes of tested tower body upper and lower is all inclined upwardly, in three sampling spots, the pipeline of any point occurs that pneumatosis makes internal pressure rise, the gas of equivalent will automatically be discharged by other two pipelines be squeezed, automatically pressure compensation is carried out, so just overcome the problem that sampling pipe accumulates too much gas, smart structural design, structural mechanics and pneumodynamics are combined, solve the difficulty occurring the necessary manual exhaust of pneumatosis, also overcome the defect that differential pressure measurement is inaccurate.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or close technical scheme with the utility model, all falls within protection domain of the present utility model.
