Background technology
The power plant boiler burning optimization is the key point that thermal power plant is safe, energy-conservation and reduce discharging.Do not have for a long time reliably a kind of and measure accurately the means of fire box temperature (field), making Optimizing 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 exit temperature; When preventing from starting, outlet temperature raises too fast and burns out and is in the reheater tube (dry combustion method) of crossing without vapor stream; Correct burning unbalanced, 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 from burning causes the serious deviation in steam water-level both sides, and major accident occurs; Prevent local overheating and flow slag; Optimize coal-air ratio, excess air coefficient is reduced in zone of reasonableness, improve burning efficiency; Prevent partial flame overheated, reduce NOX and generate, reduce pollutant emission.
The tradition temperature measuring device for hearth is mainly telescopic thermometer, and the shortcoming that this class 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 and acts on very limited.
Domestic extensive employing infrared high-temperature measurement instrument is to thermometric in furnace chamber at present, existing temperature measurer is generally by Multi-stage sleeve, probe to be fixedly installed, and then the body of heater upper shed is fixedly installed on opening part with it, but, after using a period of time, flue dust in furnace chamber can stop up the opening part of sleeve pipe, this just causes test result mistake to occur, opening part is blocked but present temperature measurer can only be test result could find when apparent error occurring the time, in this just causes for a long time, monitoring is inaccurate, is easy to occur security incident.
Summary of the invention
The purpose of this utility model is for the technological deficiency that exists in prior art, and a kind of spectrum on line temperature measurer with visual function is provided.
For realizing that the technical scheme that the purpose of this utility model adopts is:
a kind of spectrum on line temperature measurer with visual function, comprise the purging sleeve that can stretch in the boiler side walls opening and be fixedly connected with it, front end is fixedly connected with and the inner coupling sleeve that is provided with sapphire wafer with the purging sleeve, the far-infrared spectrum probe that is fixedly connected with coupling sleeve and front end are fixedly connected with coupling sleeve and the remote sensing type infrared probe are contained afterbody sleeve in it, be fixedly installed at described coupling sleeve and purging sleeve link the reflective mirror that is obliquely installed, offer on described purging sleeve simultaneously and can observe the window that purges the sleeve openings place by reflective mirror, also be fixedly installed hermetically transparent panel on described window.
Described transparent panel is clear glass.
Described purging sleeve cross section is square, and is respectively arranged with the cylinder of blowing on two sides, described purging sleeve up and down.
Described coupling sleeve comprises cylindrical shell, described cylindrical shell center pit comprises the through hole of front portion of coaxial setting and the connecting hole at rear portion, described connecting hole diameter forms the ladder platform greater than through-hole diameter and both intersections, described connecting hole rear portion is formed with the internal thread with remote sensing type infrared probe coupling, described sapphire wafer front surface holds on the ladder platform, and the rear portion is held by the remote sensing type infrared probe.
Described air blowing cylinder opening is 30 ° of angles towards front end and described purging cartridges sides.
Compared with prior art, the beneficial effects of the utility model are:
Whether the utility model is by arranging reflective mirror on coupling sleeve, can directly check by transparent panel by reflective mirror to purge sleeve openings place situation, can in time find blockedly, avoids because the inaccurate safety problem that produces of monitoring temperature.
As preferred version; anterior purging sleeve design is the square-section; when being convenient to arrange, the cylinder of blowing to dwindle the sectional area that purges sleeve as far as possible; make it satisfy the operating mode demand that is arranged between two water screen tubes; avoid the transformation to water screen tube; can not shut down the installation of carrying out the spectrum on line temperature measurer, improve ease of use.
