Description
Technical field
The present invention relates to a kind of temperature testing methods more particularly to a kind of carbon industry production aluminium anode in pot type furnace charge
Temperature Distribution test method in tank.
Background technique
In recent years, since pot type burner has production stability good, the advantages such as product quality is high, scaling loss is small, in cost of material
Under the premise of rising range is biggish, pot type burner becomes the calcining first choice stove of numerous owners favor, and has located compared to rotary kiln
The superseded phase in the field.The research and technology application in therefore calcining petroleum coke field at home, pot type burner is unprecedented popular.
But pot type burner depends primarily on fire path temperature distribution situation to the quality control of calcined coke since structure is complicated,
And actually either in pot type burner quirk vacuum cavitations or Temperature Distribution control, core is to stone in pot type burner batch can
The Temperature Distribution of oil coke controls, the different corresponding different batch can Temperature Distributions of fire path temperature distribution, while also corresponding to different
Calcined coke product quality.And all it is now the temperature in fire detecting road, but the temperature in batch can is estimated, therefore temperature point in batch can
The measurement of cloth becomes problem, and the actually Temperature Distribution is distributed system to fire path temperature, and adjustment calcine technology system has very heavy
The directive significance wanted.
Summary of the invention
A kind of batch can temperature testing method that the present invention proposes to solve the above-mentioned problems, it is therefore an objective to normal in pot type burner
During production, Temperature Distribution in batch can detected under the premise of not influencing production, obtains batch can in the height direction
Temperature distribution history optimizes calcine technology system, Improving The Quality of Products.
Thermocouple is inserted into steel pipe by a kind of batch can temperature testing method of the invention for the above-mentioned purpose, is used in steel pipe
Thermocouple to be fixed after the filling of powder filler material, thermocouple is connected to digital display meter using compensating wire, steel pipe is inserted into batch can,
It is inserted into from loading hopper center, is inserted into the depth location that calculated in advance is set, after waiting digital display meter data stabilization, by entire steel
After pipe up pulls out fixed height, continue to test next test point temperature.
The thermocouple be band alloy sleeve N-type armoured thermocouple, long-term use temperature be not higher than 1200 DEG C, length with
Loading hopper top surface to the height that furnace body exports is advisable.
The powder filler material is alumina powder, dries aluminium oxide moisture before test, is inserted into steel pipe in thermocouple
Afterwards, alumina powder is poured into steel pipe, fills the gap of thermocouple and steel pipe, it is desirable that filling is closely knit.
The model of the compensating wire is consistent with thermocouple, and compensating wire length is 5-10m longer than the length of thermocouple, energy
Resistance to 200 DEG C of high temperature.
The model of the digital display meter is consistent with thermocouple, is N-type thermocouple digital display meter, precision ± 0.1 DEG C, the range upper limit
It is 1300 DEG C.
A cast iron centrum is welded in the steel pipe open top, bottom end.
Refer to that fluctuation is less than 0.1 DEG C in 5 seconds after the waiting digital display meter data stabilization.
It is described according to temperature distributing rule on batch can inner height direction, in batch can steel pipe temperature measuring point the 5th layer of quirk with
The height up pulled out every time when lower regional location is 10cm, area above 20cm.
Advantages of the present invention: in the case where guaranteeing that pot type burner normally produces, to batch can under the premise of not influencing production
Interior temperature of charge distribution is tested, and the device is simple, easy to operate, and detection data can optimize fire path temperature distribution and technique system
Degree, Improving The Quality of Products.
