Description
Technical field
The utility model relates to the Treatment of Industrial Water field, and more particularly, the utility model relates to a kind of steam sampler for oil.
Background technology
At present, (unit generated energy 〉=600MW) the and when steam quality of Industrial Boiler is monitored under the equal conditions adopts sampler to the rear assay of taking a sample of the steam in the boiler heating power system usually for large capacity, high parameter station boiler.On the one hand, because saturated vapour is the two-phase flow that steam and water droplet form, on the other hand, in overheated, the reheated steam then with a small amount of particle, these particles contain the various resolvability ions that reflect steam quality, therefore sampler for guaranteeing the representativeness of sample, should make the flow velocity of the sample steam that enters sampler near the actual flow velocity (isokinetic sampling) of steam in the pipeline, so should reduce the disturbance that vapor flow is produced as far as possible as far as possible; In addition, in order to improve fuel utilization efficient, temperature, the pressure and other parameters of existing boiler improve constantly, and all have higher requirement for reliability and the samples' representativeness of steam sampler for oil.
See also Fig. 1, existing steam sampler for oil 20 adopts column structures usually, the one end be provided with the mouth of pipe to extension tube attached 30, the other end then adopts the mode of welding closure plate 22 to seal, and is provided with thief hole 24 near a distolateral wall of closure plate 22.During use, an end of offering thief hole 24 stretches in the jet chimney 34, and is outside then be fixed in by stub (tube) 32 on the tube wall of jet chimney 34.Although above-mentioned steam sampler for oil 20 is easy to processing, but there is following shortcoming: the first, because the column structure cross-sectional area is larger, vapor flow in the jet chimney 34 is produced larger disturbance, be difficult to realize the isokinetic sampling, therefore can reduce the representativeness of the steam sample of getting; The second, the structure of welding closure plate 22 is adopted in the sealing of steam sampler for oil 20 ends, if there is defective in welding quality, is subjected to high velocity vapor to wash away impact with thermal stress, and can there be the risk that comes off in closure plate 22 in pipeline, affect the safe operation of boiler; Three, the column structure cross-sectional area of steam sampler for oil 20 is larger, and the shearing force that produced by the steam flush effect is larger, and is therefore higher to the requirement of strength of sampler self.
In view of this, necessaryly provide a kind of stable, reliable, safe steam sampler for oil.
The utility model content
The purpose of this utility model is: provide a kind of stable, reliable, safe steam sampler for oil, to guarantee the safe operation of boiler.
To achieve these goals, the utility model provides a kind of steam sampler for oil, and it comprises integrated cylindrical portion and tapered portion, and the through hole on the axis located therein, tapered portion stretches in the main steam line, offers the thief hole that is connected with through hole on the tapered portion.
As a kind of improvement of the utility model steam sampler for oil, the end of described cylindrical portion is run through by through hole, and the end of tapered portion is then sealed by integrated top board and do not run through by through hole.
As a kind of improvement of the utility model steam sampler for oil, the quantity of described thief hole is no less than two.
As a kind of improvement of the utility model steam sampler for oil, the aperture of described thief hole is φ 2 ~ φ 8mm.
As a kind of improvement of the utility model steam sampler for oil, the aperture of described thief hole is preferably φ 5mm.
As a kind of improvement of the utility model steam sampler for oil, described steam sampler for oil also comprise be connected in the cylindrical portion end to extension tube attached.
As a kind of improvement of the utility model steam sampler for oil, described steam sampler for oil is fixed in main steam line by the stub (tube) that is sheathed on its cylindrical portion.
As a kind of improvement of the utility model steam sampler for oil, described steam sampler for oil is fixed in stub (tube) by the mode of welding or be threaded, and described stub (tube) is fixed on the tube wall of main steam line with welding manner.
As a kind of improvement of the utility model steam sampler for oil, the end of described cylindrical portion is directly formed to extension tube attached, and whole steam sampler for oil is processed by stainless steel bar integral body.
Compared with prior art, the utility model steam sampler for oil is the combination of column and taper, its tapered portion places in the main steam line, farthest reduced the disturbance of probe to the vapor flow in the main steam line, impact and the wearing and tearing of steam to sampling head have been reduced, and guaranteed that steam can enter in the thief hole of tapered portion with fluidised form preferably, and be conducive to finish the isokinetic sampling, make institute's sample thief representative.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model steam sampler for oil and useful technique effect thereof are elaborated.
Fig. 1 is the structural representation of existing steam sampler for oil.
Fig. 2 is the structural representation of the utility model steam sampler for oil.
Embodiment
See also Fig. 2, the utility model steam sampler for oil comprises integrated cylindrical portion 64 and tapered portion 66, then is provided with through hole 62 on the axis.The end of cylindrical portion 64 is run through by through hole 62, and the end of tapered portion 66 is then sealed by integrated top board 660 and do not run through by through hole 62.Offer the thief hole 68 that is connected with through hole 62 on the tapered portion 66, the quantity of thief hole 68 is no less than two, and the aperture is φ 2 ~ φ 8mm, is preferably φ 5mm.In embodiment shown in Figure 2, the end of cylindrical portion 64 with extension tube attached 80 is connected, in other embodiments, also the end of cylindrical portion 64 can be directly formed to extension tube attached, namely whole steam sampler for oil is processed by stainless steel bar integral body.
During use, tapered portion 66 stretches in the main steam line 82, steam sampler for oil is connected on the tube wall of main steam line 82 by the stub (tube) 84 that is sheathed on cylindrical portion 64, wherein, being connected to welding or being threaded between steam sampler for oil and the stub (tube) 84, stub (tube) 84 is fixed in the tube wall of main steam line 82 with welding manner.
