Description

The spectrum on line temperature measurer

Technical field

The utility model relates to a kind of temperature measuring equipment, specifically relates to a kind of remote sensing formula spectrum on line temperature measurer.

Background technology

The power plant boiler burning optimization is thermal power plant's safety, the energy-conservation and key point that reduces discharging.Do not have reliably a kind of for a long time and measure the means of fire box temperature (field) accurately, make optimized combustion lose the foundation of direct monitoring and differentiation.The importance that fire box temperature (field) is measured shows as: prevent too high superheater coking and the overtemperature of tube wall of causing of furnace outlet temperature; When preventing to start outlet temperature raise too fast with burn out the reheater tube (dry combustion method) that is in no vapor stream and crosses; It is unbalanced to correct burning, and the deviation of in time finding and correcting both sides cigarette temperature, steam temperature prevents that flue gas is amesiality and causes that this side wall weares and teares, coking; The deflection that prevents to burn causes the serious deviation in steam water-level both sides, and major accident takes place; Prevent local overheating and flow slag; Optimize coal-air ratio, excess air coefficient is reduced in the zone of reasonableness, improve burning efficiency; It is overheated to prevent partial flame, reduces NOX and generates, and reduces pollutant emission.

Traditional burner bore temperature measurement mechanism is mainly telescopic thermometer, and the shortcoming that this type technology exists is: it is very long that probe gos deep into burner hearth, heavy, yielding bite, and failure rate is high.In addition, probe is limited by heatproof, and it allows the serviceability temperature scope very limited with effect.

Summary of the invention

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain:

Shown in Fig. 1-5, the spectrum on line temperature measurer of the utility model comprises mounting flange 1, and nigger 2 purges sleeve 3 and coupling sleeve 4, the remote sensing formula infrared probe 6 that afterbody sleeve 5 is interior with being arranged on the afterbody sleeve hermetically.

Described mounting flange 1 is a circular ring; Be formed with the mounting hole that even interval is provided with on its outer peripheral edges; Its center is formed with through hole; Described through-hole wall face is formed with internal thread, is formed with the external thread that matees with described internal thread at described nigger 2 and mounting flange opposite side simultaneously, utilizes helicitic texture that described mounting flange is fixedly connected with nigger.

The cylinder-like structure that described nigger 2 is processed for metal material, it is formed with external thread structure to be fixedly connected with purging sleeve coupling equally with the different opposite side of mounting flange.

Described purging sleeve 3 is formed with the tubular structure of female thread structure for two ends; Be set with glass plate 31 in inboard, described purging sleeve right part; Be tightly connected through asbestos pad between described glass plate 31 and purging sleeve, it will purge sleeve and be divided into the not connected two parts cavity in the left and right sides.Be set with purging ring 32 at described glass plate 31 left parts; Described purging ring 32 is the coaxial circular cavity body structure that purges in the sleeve 3 that is fixedly installed on of coupling; On the ring side face of the described cavity left and right sides, be respectively arranged with equally distributed 8 through holes 34; The cavity of described purging ring is connected with air compressor by connecting the connecting pipe 33 that purges sleeve wall; The gases at high pressure that air compressor produces get in the cavity that purges ring and ejection in through hole 34 by the road; Can effectively the dust that gathers on the glass plate be blown away with the air-flow that through hole produced of glass plate sides adjacent, simultaneously by with glass plate mutually the air-flow that through hole sprayed of heteropleural dust is blown out the purging sleeve, realize purifying the effect that purges sleeve and glass plate.

For avoiding the operating mode of the temperatures involved remote sensing formula infrared probe in the burner hearth; Improve simultaneously and purge and cooling effect; Be provided with 3 gas blow pipes 35 that extend towards afterbody equably in described purging sleeve outer peripheral edges, described gas blow pipe and described purging quill are 30 ° and are arranged on purging ring left side to angle.Described gas blow pipe 35 is communicated with air compressor by the road; The gases at high pressure that air compressor produces are discharged along oblique entering purging sleeve and from the central through hole of mounting flange through gas blow pipe; Can effectively reduce the temperature in the afterbody sleeve through the cold wind cooling, prevent the entering of cigarette ash simultaneously.

Described connecting cylinder 4 is for right ends is formed with the tubular structure of coupling external thread structure, in described connecting cylinder, be formed with simultaneously can mate the set collar 41 that remote sensing formula infrared probe is fixing, so that its firm qualification is guaranteed the stable of this probe in it.

Described afterbody sleeve 5 is an end opening and the barrel-like structure that is formed with female thread structure at open end; Described remote sensing formula infrared probe 6 is spacing in it by firmly; On the base plate of described barrel-like structure, be formed with power lead through hole 61, to give the infrared probe energy supply of remote sensing formula and test result data is exported.Described remote sensing formula infrared probe utilizes the remote sensing principle to process, and adopts contactless probe to detect the CO in the boiler furnace ₂Flue-gas temperature, the wide spectrum infrared radiation signal that maskable is mixed and disorderly selectively receives the infrared spectrum of one or more gas radiations that preset in the burner hearth, effectively excludes in the environment other disturbing factor.Sensing range is generally 120～1649 ℃, and the product of higher temperature measurement range also can be provided according to user's requirement.This thermometer have the accuracy of detection height, easy for installation, cheap, use advantages such as durable.The characteristics such as to have the accuracy of detection level high for this instrument, and antijamming capability is strong of popping one's head in.

Further; For avoiding airborne oil droplet or water droplet that minute surface is constituted influence; On described coupling sleeve 4, also be set with oil-water separator and air filtering system, described oil-water separator is made up of shell, cyclone separator, filter core, sewage component etc.After the pressurized air that contains big gauging and water solid impurity gets into separation vessel, to revolve and descend along its inwall, the centrifugation that is produced is separated out profit and is flow to the oil-water separator bottom downwards along wall from steam flow, and then carries out the essence filtration by filter core.What adopt because of filter core is that thick, thin, ultra-fine three kinds of fibrous filters are learned folding forming, and it is little to have very high filtration efficiency (can reach 99.9%) and a resistance, and gas is during through filter core; Because stopping of filter core; Inertial collision and intermolecular Van der Waals force, electrostatic attraction and pull of vacuum and sticked to firmly on the filter material fiber, and increase gradually and become drop; Under action of gravity, splash into the separation vessel bottom, discharge by blowoff valve.Described air filtering system filter core can adopt fibre deposition type filter core, scratches glass pane surface to avoid particle to get into to purge in the sleeve with air-flow.

The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
