Abstract
The invention relates to a thermocouple temperature measuring device capable of monitoring temperature of a boiler. The thermocouple temperature measuring device is characterized by comprising a bullet casing which is arranged in a hole of the wall of the boiler, the bullet casing is formed by welding of a thermocouple core protective casing and a seamless steel pipe, one end of the thermocouple core protective casing is blocked and sealed by adopting of casting materials special for repairing of the boiler, and a thermocouple core is arranged in the bullet casing. The thermocouple temperature measuring device capable of monitoring the temperature of the boiler is strong in washing-resistance and abrasion-resistance performance, can effectively prolong service life of thermocouple, reduces production cost, ensures accuracy of a testing point of the temperature of the boiler and improves safe operation of the boiler.
Description
Technical field
The present invention relates to the Industrial Boiler applied technical field, particularly relate to a kind of thermocouple temperature measuring apparatus of monitoring boiler temperature.
Background technology
In service at boiler plant needs constantly the temperature at the positions such as boiler combustion system, boiler circuit and air and flue system is monitored, allows the operations staff accomplish timely adjustment according to temperature conditions, to guarantee the safe operation of boiler.the temperature element that general boiler uses mostly is thermopair, thermal resistance, comparatively applicable according to low-temperature space in the boiler that do not coexist of their material capabilities, but in the firing chamber, the higher district of equitemperature, returning charge chamber (peak reaches 1100 ℃), because these position working temperatures are higher, the soot dust granule that hardness is larger in addition is under strongly the washing away of high velocity stream wind transmission, make thermocouple sheath and core easy to wear, run duration very easily causes thermocouple sheath and core to burn out fracture or core charing phenomenon, thereby make the electric thermo-couple temperature distortions of transmitted data, temperature measuring equipment has lost the effective monitoring to the temperature at this position, if change the untimely normal adjustment that will affect boiler, will cause the blowing out accident when serious.Blow because of the thermocouple core during boiler operatiopn or other reason replacing inconvenience, can only wait until the blowing out replacing, so just affect the normal monitoring adjustment of boiler, increased the dangerous operation probability of boiler, the frequent thermopair of changing when blowing out, because the boiler internal space is large, temperature point is very many, only the thermocouple temperature measuring apparatus of high-temperature area installing just reaches more than 10 in burner hearth, thermocouple temperature measuring apparatus list Zhi Chengben is higher in addition, replacement cost makes more greatly the production cost expenditure increase, and has increased simultaneously labour's expenditure.
Summary of the invention
The object of the invention is to overcome the defective of above-mentioned prior art, provide a kind of resistance to erosion ability strong, not easy to wear, reduce the scaling loss probability, improve serviceable life, reduce production costs, and simple in structure, the thermocouple temperature measuring apparatus of practical monitoring boiler temperature.
The present invention is achieved through the following technical solutions:
A kind of thermocouple temperature measuring apparatus of monitoring boiler temperature; it is characterized in that: comprise the sub warhead sleeve pipe that is arranged in the boiler setting hole; described sub warhead sleeve pipe is to repair the stove dedicated pouring material by employing thermocouple core protective casing and the weldless steel tube of one end shutoff is welded, and in this sub warhead sleeve pipe, thermocouple core is installed.
Described weldless steel tube external diameter is identical with the thermocouple protective casing internal diameter.
Described thermocouple core protective casing adopts Gao Lao, wear-resisting, high temperature resistant material to make.
The thermocouple temperature measuring apparatus resistance to erosion of monitoring boiler temperature of the present invention, abrasive resistance are strong, can effectively improve thermopair serviceable life, reduce production costs, and can guarantee the accuracy of boiler temperature measuring point, improve the safe operation of boiler.
The present invention is applicable to industrial steam boiler, and all need the zone of temperature monitoring, very applicable to temperature higher part position, be particularly suitable for industrial and mining enterprises, in medium temperature and medium pressure Natural Circulation fluid bed boiler furnace, the high temperature such as the bed of material, material returning device need the technical field of monitor temperature.
Description of drawings
Fig. 1 is the structural representation sketch of thermocouple temperature measuring apparatus in prior art;
Fig. 2 is the structural representation sketch of the present invention's thermocouple temperature measuring apparatus of monitoring boiler temperature.
Embodiment
As shown in Figure 1, thermocouple temperature measuring apparatus in prior art is that a thermocouple sheath 3 is installed in the set hole of boiler setting 1, then thermopair 3 is contained in this thermocouple sheath 3, in this design, thermopair 3 stretches out the sleeve pipe rearward end and is in boiler furnace, easily causes wearing and tearing.
The thermocouple temperature measuring apparatus of monitoring boiler temperature of the present invention is that a sub warhead sleeve pipe is installed in boiler setting 1 hole; this sub warhead sleeve pipe is to repair stove dedicated pouring material 8 by employing thermocouple core protective casing 7 and the weldless steel tube 4 of an end shutoff is welded; wherein the external diameter of weldless steel tube 4 is identical with thermocouple protective casing 7 internal diameters, and thermocouple core 4 is arranged in the sub warhead sleeve pipe.The thermocouple core protective casing adopts Gao Lao, wear-resisting, high temperature resistant material to make.
Boiler is being stopped transport between maintenance or standby period; the thermocouple protective casing 7 of first boiler high temperature zone being manufactured as fire box, material returning device equitemperature measuring point place; put into the hole of former installing thermocouple sheath; again thermocouple protective casing 7 and weldless steel tube 4 are welded; then this thermocouple protective casing 7 is stopped up at inboard wall of burner hearth with repairing the stove dedicated pouring material, play the sealing effect of supporting sleeve weight simultaneously.Weldless steel tube 4 being welded on burner hearth exterior wall backplate 3(as shown in Figure 2 at last, is that heat-insulation layer 2,6 is pad between boiler setting 1 and burner hearth exterior wall backplate 3), at last thermocouple core 5 is put into inside pipe casing, wiring debugging completion.
