Abstract
The utility model discloses a temperature measuring optical cable, which belongs to the field of optical fibers, and aims at solving the problems that an optical cable resists low temperature and can not be used to monitor surface temperature of a coal gasifier. The temperature measuring optical cable comprises a cylindrical bare optical fiber, a coating layer is arranged on the periphery of the bare optical fiber in the radial direction, an inner protection sleeve layer is arranged on the periphery of the coating layer in the radial direction, a soft pipe layer is arranged on the periphery of the inner protection sleeve layer in the radial direction, and an outer protection sleeve layer is arranged on the periphery of the soft pipe layer in the radial direction. The temperature measuring optical cable can be used to measure the surface temperature of the coal gasifier.
Description
Technical field
The utility model belongs to the fiber optic applications field, relates in particular to the temperature test technology.
Background technology
Coal gasifier claims again producer gas generator, is the major equipment of coal gasification, because the coal gasifier device is inner, need to be operated under the high temperature and high pressure environment condition, internal temperature is usually more than 1300 ℃, through the heat insulation processing of refractory brick, is transmitted to the temperature on gasification furnace surface usually 130 ℃ of left and right; In case refractory brick finedraw occurs, comes off, after attenuation, the body of heater surface temperature can significantly rise, and affects body of heater protection intensity, due to internal high pressure, very serious consequence can occur.
Monitor the coal gasifier surface temperature with distributed optical fiber temperature sensor, can non-blind area, accurate temperature measurement is also oriented the temperature anomaly point; For the support equipment safe operation provides good solution.
But because common temperature measuring optical cable exists some problems, such as:
1. working temperature is low, and the ordinary optical cable maximum operating temperature is generally at 85 ℃;
2. traditional temperature measuring optical cable external diameter is 3mm, and thermal conductivity is relatively poor.
The utility model content
In view of this, be necessary for the problems referred to above, a kind of temperature measuring optical cable be provided, the utility model by the following technical solutions:
A kind of temperature measuring optical cable, comprise cylindrical bare fibre, described bare fibre outer radial periphery encloses and is equipped with coat, and described coat outer radial periphery encloses and is equipped with inner restrictive coating, described inner restrictive coating outer radial periphery encloses and is equipped with hose layer, and described hose layer outer radial periphery encloses and is equipped with external sheath layer.
In the temperature measuring optical cable of the utility model scheme, described coat material is polyimide; Described inner restrictive coating material is teflon; Described hose layer material is stainless steel; Described external sheath layer material is teflon.
In the temperature measuring optical cable of the utility model scheme, the diameter of described temperature measuring optical cable is 2mm.
In the temperature measuring optical cable of the utility model scheme, described teflon external sheath layer external diameter is 2mm, and internal diameter is 1.5mm.
In the temperature measuring optical cable of the utility model scheme, described stainless hose layer internal diameter is 1.3mm, and external diameter is 1.6mm.
In the temperature measuring optical cable of the utility model scheme, described teflon inner restrictive coating external diameter is 0.6mm.
The beneficial effects of the utility model are: owing to adopting polyimide (Polyimide) material as coat, make the working temperature of coat be increased to more than 300 ℃; Owing to using polytetrafluoroethylmaterial material as inner restrictive coating and external sheath layer, make inner restrictive coating, external sheath layer working temperature be increased to more than 260 ℃; Because the external diameter with optical cable is decreased to 2mm from 3mm, improve heat conductivility.
Description of drawings
Fig. 1 is the radial section schematic diagram of the utility model temperature measuring optical cable.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further detailed.
In Fig. 1, bare fibre 1 is at the center, and its tolerable temperature reaches more than 1200 ℃ usually; Be coat 2 in the outside of bare fibre 1, adopt polyimide material, make bare fibre 1 have pliability, non-friable, and the polyimide material tolerable temperature reaches more than 300 ℃; Are inner restrictive coatings 3 in the outside of coat 2, adopt polytetrafluoroethylmaterial material, optical fiber is played the effect of further protection and waterproof, the polytetrafluoroethylmaterial material tolerable temperature reaches more than 260 ℃; The outside of inner restrictive coating 3 is hose layers 4, adopts stainless steel material, plays the resistance to compression effect, and has further protected temperature-measuring optical fiber; The outside of hose layer 4 is external sheath layers 5, adopts polytetrafluoroethylmaterial material, plays the effect of water proof fire retardant.
The external diameter of whole optical cable is 2mm, improves heat conductivility, has good temperature-sensitive effect.
The above embodiment has only expressed embodiment of the present utility model, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
