Abstract
The utility model belongs to the analytical instrument technical field, in particular relates to an improved external ultrasonic concentration analytical instrument. The ultrasonic wave emitter and the receiver are arranged on the exterior of the process pipeline through an external <emitting-reflection> device; the analytical instrument realizes the real-time online analysis of the liquid concentration in the pipeline where the instrument is arranged; meanwhile, the ultrasonic concentration analytical instrument can be mounted or maintained conveniently under the condition of having no influence on the process production.
Description
Technical field:
The utility model belongs to technical field of analytical instruments, is specifically related to a kind of improved ultrasound wave concentration analyzer, i.e. the ultrasound wave concentration analyzer of external.
Background technology:
Existing ultrasound wave concentration analyzer detecting device is the flow type detecting device.So-called flow type is with ultrasound emission and being made of one of reflection sensor, and a measuring flume that places measured medium to flow through this sensor.Its shortcoming is that sensing contacts with measured medium, and measured medium easily forms influences such as corrosion to sensor.
Summary of the invention:
The purpose of this utility model is for overcoming above-mentioned defective, and after to the improved basis of existing ultrasound wave concentration analyzer, a kind of of proposition places outside the measured medium pipeline, just can real-time online analyzes the external-placed type supersonic concentration analyzer of its concentration.
The utility model proposes a kind of principle of utilizing process pipe as " emission-reflection " device, hyperacoustic emission and reception are positioned over outside the process pipe, so not only solve the anticorrosion problem of " emission and reception " device of supersonic wave analyzer, also be convenient to the I﹠M of instrument.
The utility model is achieved like this: it comprises the ultrasound wave concentration analyzer, it is characterized in that it also comprises threeway and the four-way pipe fitting that is connected with process pipe, the side outlet of threeway is provided with the temperature sensor platinum resistance thermometer sensor,, links to each other with the ultrasound wave concentration analyzer; The a pair of outlet of four-way side is provided with a pair of sealed glass visor respectively, and one of them glass visor is equipped with ultrasound wave sending and receiving dual-purpose sensor outward, and links to each other with the ultrasound wave concentration analyzer.
The utility model external-placed type supersonic concentration analyzer usually, its threeway, four-way and process pipe be connected and pipe fitting outlet, glass visor all are to connect by steel flange; Side outlet in threeway is provided with platinum resistance thermometer sensor, as temperature sensor; The transducer that ultrasound wave sending and receiving dual-purpose sensor adopts piezoceramic material to manufacture.
Description of drawings:
Accompanying drawing 1 is the utility model example structure simplified schematic diagram.
Accompanying drawing is described mainly to be the external part-structure synoptic diagram that is connected with the ultrasound wave concentration analyzer, among the figure, and 1-ultrasonic reflections face; The 2-sensor for measuring temperature; 3-glass visor; The 4-ultrasonic emitting, accept sensor; 5-lining tetrafluoro steel four-way; The threeway of 6-lining tetrafluoro steel.
Embodiment:
Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.
Embodiment:
At the process pipe of measured medium, the caliber size of pressing process pipe inserts a threeway 6 and four-way 5, and threeway 6 and four-way 5 are connected by flange, and the flange size is consistent with the flange of process pipe bore, makes things convenient for connection.
On the side flange of threeway 6, adorn a platinum resistance thermometer sensor, by the size of this flange, promptly sensor for measuring temperature 2, measure the temperature of measured medium, link to each other with the ultrasound wave concentration analyzer, calculate for the temperature compensation of ultrasound wave concentration analyzer.The a pair of flange of threeway then inserts on the process pipe, for the circulation of measured medium.
The a pair of flange of four-way 5 inserts on the process pipe, for the circulation of measured medium.Then with a pair of glass visor sealing, the glass visor is outward a steel flange to a pair of flange of side.On a steel flange ultrasound wave sending and receiving dual-purpose sensor 4 can be installed therein, link to each other with the ultrasound wave concentration analyzer.This sensor 4 is formed the ultrasound wave reception-surface of emission with adjacent glass visor 3, and another steel flange and adjacent glass visor are then formed reflecting surface 1.
Because ultrasound wave receives and emission sensor is mounted in outside the glass visor, thereby can under the condition that does not influence explained hereafter, install easily or reception of maintenance ultrasound wave and emission sensor.
Ultrasound wave sending and receiving dual-purpose sensor, when being realization sound-critical piece of electricity conversion, normally adopt piezoceramic material to manufacture transducer, piezoelectric ceramics is a kind of stupalith with piezoelectric effect and inverse piezoelectric effect.Do the time spent when it is stressed, can produce electric signal, otherwise when it is subjected to electric field action, can produce stress and strain, utilize this characteristic of piezoelectric ceramics, artificially it be applied a pulse voltage, make it produce ultrasonic vibration (being hyperacoustic emission), when the ultrasonic reflections ripple returned on the arrival piezoelectric ceramics, because the effect of acoustic pressure, it can produce the pulse electromotive force.Realized the conversion of electricity-sound, sound-electricity like this.
The ultrasound wave trigger pip after shaping, triggers radiating circuit, excite piezoelectric ceramic wafer, it is vibrated, produce ultrasound wave, ultrasound wave sends from transducer, and to reflecting surface, the echo that reflects is received by wafer through solution, after amplifying shaping, send pulse-width conversion circuit, obtain and concentration, the relevant pulse width of temperature, behind counting circuit, convert serial data again to, send signal processor to.
Temperature signal, after temperature-pulse-width conversion circuit that triggering is made up of AD590 is delivered to counting circuit, converts digital serial signal to and sends signal processor to after shaping also by the temperature triggered signal controlling.Ultrasonic signal and temperature signal can draw the concentration of measured medium after signal processor calculates.
