Description
Affiliated technical field
The present invention relates to a kind of non-contact measurement apparatus and method thereof of gas temperature field of blast furnace throat.
Background technology
Blast furnace throat coal gas distributions is the important symbol of reflection conditions of blast furnace, mainly characterizes by the furnace throat gas temperature.At present, the measurement of blast furnace throat gas temperature mainly is to adopt cross temperature measurer, and this device is made up of four thermometric girder steels that insert blast furnace throat, several somes thermocouple measurement furnace throat gas temperatures that utilize every steel beam bottom to arrange.But after cross temperature measurer can only be measured the furnace throat limited temperature spot that directly makes progress, particularly blast furnace and maximizes, the thermometric blind area was bigger, can not reflect whole furnace throat planar coal gas distributions comprehensively, causes the erroneous judgement of coal gas stream easily; The thermometric girder steel is washed away by furnace charge impact and coal gas stream for a long time because of stopping roof material distributing in addition, and the equipment rapid wear also can aggravate the furnace charge efflorescence, changes shape of charge level, influence the coal gas distribution, even influence smooth operation of furnace.
Summary of the invention
Influence the deficiency of cloth in order to overcome existing blast furnace throat coal gas measuring apparatus measurement point finite sum, the invention provides a kind of furnace throat gas temperature field measurement device and method, can the whole furnace throat planar of non-contact measurement temperature field, and do not influence blast furnace material distribution.
The technical solution adopted for the present invention to solve the technical problems is: measuring apparatus comprises sound wave emissions receptor, amplifier, controller, computer and monitoring software, on the tested plane of blast furnace throat steel brick, be provided with mounting sleeve, the telescopic outward flange is connected with the companionflange of sound wave emissions, receptor, sound wave emissions, receiver front end connect mini microphone, end is connected with source of the gas with magnetic valve through Venturi tube, the signal wire of magnetic valve and mini microphone is connected with controller, and controller is connected with supervisory control computer.
At the acoustic wave propagation path that furnace throat central zone and fringe region are provided with, the point of crossing that makes center and peripheral zone sound wave path is more than the central zone, realizes the unequally accurate measurement of tested plane temperature field.
The pressure of described source of the gas is required sounding pressure of sound wave emissions, receptor and furnace top pressure sum.
Utilize velocity of propagation and funtcional relationship gas temperature between of sound wave in gaseous media that gas temperature field of blast furnace throat is carried out non-contact measurement.1. organize sound wave emissions, receptor in the tested Plane Installation of blast furnace throat more, on projector, connect the gas of certain pressure as the sounding source of the gas, because the distance between projector and the receptor is known, measures sound wave and just can calculate medial temperature on this path in the travel-time on the detected space path; 2. many group sound wave emissions, receptor form many acoustic wave propagation paths in whole tested plane, each acoustic receiver is set according to demand can only receives the acoustic signals that the fixed pinger sends, form specific sound wave path, by the program of setting, order opens and closes each sound wave emissions, receptor, acoustic signals obtains every paths acoustic transit time and path temperature after amplifier and controller processing, be transferred to the computer monitoring device; 3. monitoring device utilizes interpolation algorithm to simulate tested planar temperature field, and provides the information of the visualizes such as isothermal map, path profile, block diagram and time trend figure of detected space.
For obtaining better effect, step 1. described in source of the gas select nitrogen, the pressure of nitrogen source of the gas is sound wave emissions, receptor (1) required sounding pressure and furnace top pressure sum.
The invention has the beneficial effects as follows, can noncontact under the prerequisite that does not influence blast furnace material distribution, measure the tested planar gas temperature field in furnace throat position accurately, and then obtain the real-time coal gas distributions of whole furnace throat planar situation, the accurate cloth that cooperates distribution device, thereby obtain rational coal gas distributions, help the stable smooth operation of realizing that blast furnace is produced.Equipment is all installed outside stove in addition, and is simple in structure, easy to maintenance, is not subjected to the influence of furnace high-temperature, high pressure, high dust.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is acoustic wave propagation path figure.
1. sound wave emissions, receptor among the figure, 2. mounting sleeve, 3. last furnace shell, 4. throat armour.
Embodiment
Level is offered open holes and fabrication and installation sleeve pipe 2 on the tested plane of blast furnace throat steel brick 4 shown in Figure 1, sleeve pipe 2 is poured into a mould refractory matter or filling fire resisting material outside the oviduct of the inside of furnace shell 3, and with furnace shell 3 welded seals, the outward flange of sleeve pipe 2 is connected with the companionflange of sound wave emissions, receptor 1.Termination mini microphone before the sound wave emissions, receptor 1, terminal through Venturi tube and the external source of the gas of magnetic valve, source of the gas is selected nitrogen, and the pressure of nitrogen source of the gas is sound wave, projector 1 required sounding pressure and furnace top pressure sum.All control signals of method are controlled by peripheral control unit.
Difference according to attention rate, can carry out the unequally accurate measurement in temperature field, acoustic wave propagation path in furnace throat central zone and fringe region setting, the point of crossing that makes center and peripheral zone sound wave path is more than the central zone, makes the gas temperature field in above two zones have higher measuring accuracy.In the embodiment of Fig. 2,16 sound wave emissions, receptors 1 evenly are installed in outside the furnace shell 3, wherein mark the pinger that is of T, mark R's is acoustic receiver, acoustic wave propagation path shown in Figure 2, it is more to make the paths intersect at furnace throat edge and center put relative region intermediate, and the gas temperature in furnace throat edge and centre can obtain higher precision like this.
