Description
Technical field
The utility model relates to burner hearth thermometry field, particularly relates to a kind of spectrum on line temperature measurer of easy to clean.
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, the flue dust in furnace chamber can stop up the opening part of sleeve pipe; this just causes test result mistake to occur; need in time to shut down to take cleaning apart, this just causes monitoring temperature to stop, and when consisting of image to producing, complex operation is complicated.
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 of easy to clean 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 of easy to clean, comprise the purging sleeve that can stretch in the boiler side walls opening and be fixedly connected with it, the afterbody sleeve that front end is fixedly connected with the purging sleeve, be fixedly installed on the far-infrared spectrum probe of described afterbody sleeve inner, wherein, offer the ash disposal mouth at described purging sleeve top or sidepiece, dismountable upper cover is with the sealing of ash disposal mouth, and described upper cover is that strip is removed in order to stretch into to purge in sleeve and with the dust of its opening part from the ash disposal mouth.
Described upper cover is bolted to connection with the purging sleeve.
It is long and narrow square that the front opening of described purging sleeve is, and the rear end is progressively outwards heaved from postmedian and transitted to round section.
The bottom surface of the front opening of described purging sleeve is downward-sloping to increase aperture area.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is by arranging ash disposal mouth and strip upper cover; when needs cleaning opening part dust; upper cover is taken off and inserts in the ash disposal mouth dust is removed; it is simple to operate; not needing integral body to take apart can clear up; even do not need another standby dust removing tool, avoided shutting down the monitoring that causes and stopped, having guaranteed to produce and steadily carried out.
As preferred version, anterior purging sleeve design is that front end is long and narrow square-section, makes it satisfy the operating mode demand that is arranged between two heating tubes, avoids the transformation to heating tube, can not shut down the installation of carrying out the spectrum on line temperature measurer, improves ease of use.
Description of drawings
Figure 1 shows that the inner structure schematic diagram of spectrum on line temperature measurer of the present utility model;
Figure 2 shows that the packaging structural representation of spectrum on line temperature measurer of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As illustrated in fig. 1 and 2, spectrum on line temperature measurer of the present utility model comprises the purging sleeve 1 that can stretch in the boiler side walls opening and be fixedly connected with it, the afterbody sleeve 2 that front end is fixedly connected with the purging sleeve, and far-infrared spectrum probe 3.Described afterbody sleeve be the front opening rear end by base plate seal columnar structured, described afterbody cover tube end plate top is formed with viewing window 24, can directly check by viewing window the situation that purges the barrel forward end opening part, in time finds stopping state.Described far-infrared spectrum probe 3 be fixedly installed on the viewing window below and with purge sleeve keep before and after corresponding settings to pass through purging sleeve front openings temperature measurement on-line.Simultaneously, offer ash disposal mouth 11 at described purging sleeve 1 top, the upper cover 12 fixing with purging sleeve bolt is with the sealing of ash disposal mouth, and described upper cover 12 stretches into to purge in sleeve and with the dust of its opening part for strip so that from ash disposal mouth 11 and removes.Certainly; also the ash disposal mouth can be arranged on the positions such as side; when needs cleaning opening part dust; upper cover 12 is taken off and inserts in the ash disposal mouth dust is removed; it is simple to operate, and not needing integral body to take apart can clear up, and does not even need another standby dust removing tool; avoided shutting down the monitoring that causes and stopped, having guaranteed to produce and steadily carried out.
Wherein, described afterbody sleeve 2 open front places also are fixedly installed glass plate 4; Specifically, described afterbody barrel forward end opening inboard is formed with internal projecting ring 21, simultaneously be formed with screw thread in described internal projecting ring 21 front sides, and the wafer lock ring 22 of described screw thread coupling is held described glass plate and is positioned between internal projecting ring 21 and eyeglass lock ring 22, in the afterbody barrel forward end, glass plate is set and blocks dust and enter the rear portion, improve the operating mode of far-infrared spectrum probe.
