Abstract
The utility model relates to a furnace tube high temperature detection device, which belongs to a furnace tube high temperature detection device of an oilfield boiler and is characterized by comprising a temperature measuring element arranged on the water side on the outer layer of a furnace tube, wherein an extension line of the temperature measuring element passes through the water region of the water side and is connected to a programmable controller for realizing analysis and display of a temperature measuring result by a furnace body flange; the programmable controller is connected with a control regulating valve for regulating gas flow; the temperature measuring element is arranged on a fire tube steel plate by an outer sleeve of a sandwich temperature measuring installation head; an air isolation layer is separated out between the outer sleeve of the sandwich temperature measuring installation head and the temperature measuring element; and the sandwich temperature measuring installation head is also provided with a sealing device for realizing sealing of the temperature measuring element. The furnace tube high temperature detection device can accurately detect the temperature of the fire tube steel plate, and can also avoid the condition that the oilfield boiler needs to be shut down in the overhauling process in the prior art; and the service life of the furnace tube high temperature detection device is extended.
Description
[technical field]
The utility model relates to a kind of boiler tube high temperature checkout gear, and it belongs to the detection technique field.The furnace tube temperature checkout gear of oil field boiler particularly.
[background technology]
Fire tube steel billet temperature prior art has two kinds of detection methods at present in the flame detection district, Fig. 1 is the non-contact detecting method, utilize the infrared temperature detector, steel billet temperature from A observation B place, but, the centre isolates because of having flame, the temperature that the infrared temperature detector is detected is the temperature of flame, is not the temperature of steel plate B.Fig. 2 is the contact detection method, temperature element is installed head (also being sleeve pipe) be soldered on the steel plate, and temperature element is inserted into to be installed in the head, and the extended line of temperature element is guided to outside the stove by flame zone.This contact detection method can be measured the true temperature of steel plate, but has a fatal problem: the temperature element extension line passes flame zone, good again steel, in flame zone work, its life-span is very short for a long time, ability 3-4 month at most, need blowing out to renew then, not only influence is produced, and also increases cost.
[summary of the invention]
The purpose of this utility model is to provide a kind of temperature test result accurate, the boiler tube high temperature checkout gear that life cycle is long.
The purpose of this utility model is achieved in that
A kind of boiler tube high temperature checkout gear, it comprises the temperature element that is arranged on the outer water side of boiler tube, the extended line of described temperature element passes water side pool, be connected to a programmable controller of realizing temperature test interpretation of result and demonstration by the body of heater flange, described programmable controller connects a control and regulation valve of regulating gas flow, the outer sleeve that described temperature element is installed head by an interlayer thermometric is installed on the fire tube steel plate of boiler tube, install between the outer sleeve of head and the temperature element at described interlayer thermometric and to isolate an air barrier, install at described interlayer thermometric and also be provided with one on the head by the sealing device of realizing the temperature element sealing by slider.
On described programmable controller, also connect a color touch screen.
The sealing device of described temperature element comprises cutting ferrule and the nut that is arranged on interlayer thermometric installation crown portion, and described temperature element passes cutting ferrule and nut.
Adopt packing_seal between the extended line of described temperature element and the body of heater flange.
The utility model can detect fire tube steel billet temperature accurately, because its temperature element design and installation is in the water side, and passed through effective seal, make the body of temperature element of the present utility model can directly not contact high temperature, prolongation contact high-temperature region is only arranged, prolong service life of the present utility model, also can avoid prior art to need the situation of shutdown maintenance.

[specific embodiment]
Below in conjunction with accompanying drawing 2, Fig. 3 and Fig. 4 the utility model is further detailed:
In order to realize the purpose of this utility model, the water that will be installed in boiler tube 1 during the installation site of temperature element 5 of the present utility model is surveyed, and point for measuring temperature moves on to outer water side B district thermometric by the A of flame zone prior art, avoids the flame high-temperature region.How to solve and truly detect fire tube steel billet temperature rather than by the steel billet temperature after the water cooling, as can be known from Fig. 4.Temperature element is installed head and is divided three layers, skin directly is welded on the steel plate 2, break-even being sent to of heat of steel plate installed on the head, between a described interlayer thermometric installation outer sleeve 3 and temperature element 5, isolate an air barrier by slider 4, this realization is from the cooling effect of outer isolated water like this, the heat that is passed from interior isolate steel plate 2 keeps the temperature of detector unit 5 detected innermost layers consistent with the temperature of steel plate 2 not by water cooling.Being inserted into a temperature that interior detector unit 5 is surveyed is installed promptly is the temperature of steel plate.Temperature element 5 passes the sealing device of being made up of cutting ferrule 6 and nut 7, and concrete structure is the extended line of temperature element 5, passes by cutting ferrule 6, and by cutting ferrule 6 and nut 7 sealings, keeps temperature element to install in the head, does not intake.Temperature element 5 extended lines extend to outside the stove by body of heater flange F, and QC-1 links to each other with programmable controller, and show full detail by color touch screen HMI, regulate gas flow by control valve TV, realize the control of heating furnace load.In order to guarantee the sealing property of temperature element, when the temperature element extension is passed through the body of heater flange, need to adopt the packing_seal mode to seal.
Claims (4)
