Abstract
An antifogging sheath of an ultrasonic liquid level meter consists of a flange and a tubular heating tube. The tubular heating tube is connected with the flange, and the center circular hole of the flange is arranged inside the tubular heating tube. When detecting, an external power source provides electric quantity for the antifogging sheath, the temperature of a heating tube of the antifogging sheath is raised, and the temperature inside the heating tube is higher than that of the surface of detected slurry. Because a sound wave transmitting tube of the ultrasonic liquid level meter is arranged inside the tubular heating tube of the antifogging sheath, the temperature of the surface of the sound wave transmitting tube is higher than that of the surface of the detected liquid, and then the surface of the sound wave transmitting tube of the ultrasonic liquid level meter can not be condensed with steam, thereby increasing detection precision and accuracy.
Description
Technical field
The utility model belongs to the liquid level gauge research field, relates in particular to the antifog sheath of a kind of ultrasonic level gage.
Background technology
Along with country to SO in the fuel-burning power plant
2The strict demand of discharge capacity, the SO that need take measures to reduce of each power plant
2Discharge capacity.The employing wet fuel gas desulfurizing technology reduces the SO that contains in the flue gas at present
2A step in the wet fuel gas desulfurizing technology is to adopt the echo principle to carry out contactless level gauging to corrosivity slurries in the casing, the echometric measurement principle is to utilize emissive source to send sound wave to measured medium, calculate sound wave from the emissive source to the measured medium, again from measured medium return emissive source the distance of process.
The problem that exists is that the surface temperature of common described corrosivity slurries is 40 ℃-50 ℃, is higher than the temperature of external environment at present; When measuring, because the temperature of measurement instrument sound wave emissions end is lower than the existing environment temperature of slurries, so measurement instrument sound wave emissions end has steam coagulation, water vapor causes sound wave generation when emission to depart from and reflect, influence measurement result, the interference wave that condensate water produces when serious will make pick-up unit can't finish measurement.
The utility model content
Technical problem to be solved in the utility model provides the antifog sheath of a kind of ultrasonic level gage, can not generate condensate water when making the work of ultrasonic level gage sound wave emissions end, has improved the accuracy of detection of pick-up unit.
In order to address the above problem, the utility model is taked following technical scheme: the antifog sheath of a kind of ultrasonic level gage, described antifog sheath is made up of flange and tubulose heating tube, and described tubulose heating tube is connected with flange, and described tubulose heating tube comprises in flange center's circular hole and its.
Preferably, antifog sheath also comprises mounting bracket, and described mounting bracket top and low side all are provided with web joint.
Preferably, described flange two ends are provided with screw, and the web joint on described mounting bracket top is provided with screw.
The antifog sheath of the ultrasonic level gage that the utility model provides is made up of flange and tubulose heating tube, and described tubulose heating tube is connected with flange, and described tubulose heating tube comprises in flange center's circular hole and its.The heating tube of described antifog sheath covers on the ultrasonic level gage sound wave emissions end, mounting bracket connects described antifog sheath, the heating tube of described antifog sheath is fixed on the casing that loads corrosivity slurries to be detected by mounting bracket, in detecting casing during the degree of depth of corrosivity slurries, heating tube energising heating, guarantee that the temperature in inside pipe casing zone is higher than the temperature of corrosivity slurries in the casing, the air themperature that is ultrasonic level gage sound wave emissions end zone of living in will be higher than the air themperature of measuring in the casing, because the moisture that contains in the heating region air can be unsaturated fully, so ultrasonic level gage sound wave emissions end can be because of the condensation bleed, prevented that effectively ultrasonic level gage sound wave emissions end from generating condensate water, improved the accuracy of detection of pick-up unit.
Description of drawings
Fig. 1 is the antifog jacket structure synoptic diagram of the utility model ultrasonic level gage;
Fig. 2 is the antifog sheath preferred version of a ultrasonic level gage described in the utility model structural representation.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model ultrasonic level gage comprises: liquid level gauge body 11 and antifog sheath 12, described antifog sheath 12 is by flange 111 and tubulose heating tube 112, described flange 111 screws with the sound wave emissions pipe 13 of ultrasonic level gage and is connected, described tubulose heating tube 112 is connected with flange 111, and the sound wave emissions pipe 13 of described ultrasonic level gage passes flange and stretches in the heating tube.
As shown in Figure 2, for being fixed on, the ultrasonic level gage that has antifog sheath that the utility model is provided detects the casing top, the utility model ultrasonic level gage also comprises a mounting bracket, the top of described mounting bracket 21 and low side all are provided with web joint, the web joint 22 on described mounting bracket 21 tops is provided with screw hole, screws with the flange of antifog sheath by screw to be connected; The mode that the web joint 23 of mounting bracket 21 low sides spins by screw is connected with the top of detecting casing or is connected with the top of detecting casing by the mode of welding.
When detecting, external power supply provides electric weight for antifog sheath, and the heating tube temperature of antifog sheath raises, and the temperature in the heating tube is higher than the surface temperature that detects slurries; Because the sound wave emissions pipe of ultrasonic level gage is in the tubulose heating tube of antifog sheath, the temperature of described sound wave emissions tube-surface is higher than the surface temperature of tested slurries, so the sound wave emissions tube-surface of ultrasonic level gage does not have steam coagulation, the precision and the accuracy that detect have been improved.
Claims (3)
1, the antifog sheath of a kind of ultrasonic level gage is characterized in that, described antifog sheath is made up of flange and tubulose heating tube, and described tubulose heating tube is connected with flange, and described tubulose heating tube comprises flange center's circular hole in it.
