Ceramic tube is chooseed for use to the measuring junction sleeve pipe of this thermocouple, and the thermocouple wire adopts the noble metal, and flange department has the sealing member preventing leaking etc. And this thermocouple can be lower the use 1 to 2 cycle of coal slurry gasifier high temperature high pressure condition.
Description
Technical field
The utility model relates to a kind of thermopair, especially a kind ofly can measure gasification furnace fire box temperature and the high temperature high voltage resistant thermopair of long service life.
Background technology
Coal slurry gasifier uses more gasification furnace during coal gasification, chemical fertilizer etc. are produced, the feature of this gasification furnace be fire box temperature more than 1300 DEG C, pressure is greater than 4Mpa, has firebrick structure; General every platform gasification furnace needs 3 to 4 thermopairs to carry out thermometric to its burner hearth, therefore just needs the thermopair of energy high temperature high voltage resistant.
The gasification furnace High Temperature High Pressure thermocouple measurement end sleeve pipe now used generally adopts the ceramic-like non-metallic materials such as corundum, silit, molybdenum disilicide, the feature of these materials is high temperature resistant, but impermeability and mechanical property poor, hardness is high, easy fracture, particularly rapid heat cycle easily cause the fracture of these sleeve pipes.These sleeve pipes general are shorter than 1 cycle in serviceable life in coal slurry gasifier, this very large inconvenience to produced on-site band.
Summary of the invention
For overcoming prior art Problems existing, the utility model provides a kind of can measure gasification furnace fire box temperature and the gasification furnace High Temperature High Pressure thermopair of long service life, this thermopair selects metal ceramic tube by measuring junction sleeve pipe, thermocouple wire adopts noble metal, flange is with the composition such as seal of anti-leak, and this thermopair can use 1 to 2 cycles under coal slurry gasifier high-temperature and high-pressure conditions.
The technical solution of the utility model is achieved in that a kind of gasification furnace High Temperature High Pressure thermopair, comprise measuring junction sleeve pipe, metal sleeve, described measuring junction sleeve pipe is made up of metal ceramic tube, little ceramic pipe, large ceramic pipe, thermocouple wire, thermocouple wire is installed with in described little ceramic pipe, large ceramic pipe is socketed with outside little ceramic pipe, large ceramic pipe is socketed metal ceramic tube outward, metal ceramic tube is connected with metal sleeve by screw thread, and described large ceramic pipe, little ceramic pipe and thermocouple wire extend to metal sleeve upper end.
Connection of thread between described metal ceramic tube and metal sleeve scribbles high-temperature plastic.
Described metal sleeve upper end and large ceramic pipe, little ceramic pipe and thermocouple wire junction are filled with fluid sealant.
Be provided with external thread outside described metal sleeve, and be connected by external thread and thread bush are adjustable, metal sleeve is provided with set nut, and the metal sleeve and thread bush that are adjusted to designated length is locked by set nut.
Described thread bush is fixedly connected with joint flange by circlip, thermocouple wire overcoat has insulation course and passes from flange hole, joint flange upper end to be sealedly and fixedly connected terminal box by internal thread, plain cushion and seal assembly, described thermocouple wire through seal assembly to terminal box.
The adapter flange be contained on gasification furnace is connected below described joint flange.
The beneficial effects of the utility model are:
1, metallic ceramics selected by measuring junction sleeve pipe, and metallic ceramics sleeve pipe can be connected with metal sleeve by screw thread, makes connection more solid and reliable; Metallic ceramics sleeve pipe plasticity is good, is not easy fracture when rapid heat cycle; Impermeability is run well than ceramic-like cover, and Korrosionsmedium can not be entered in sleeve pipe; Heat conductivity is run well than ceramic-like cover, makes hot thermocouple response speed faster.
2, thimble assembly and thread bush are threaded connection, and can regulate insertion depth, regulate insert deeply according to the thickness difference of gasification furnace refractory brick, and the measurement that can meet client requires and can guarantee the serviceable life of product.
