Abstract
The invention relates to a coke oven body temperature measurement hole setting method with strong anti-interference performance, and belongs to the field of coke ovens. The method is characterized in that: temperature measurement holes are formed in a coke oven chute zone. The temperature measurement holes are cylindrical blind holes along the direction of a coke oven cross wall, the section diameter of the blind holes is 20 to 100mm, and the length of the blind holes is 1,000 to 5,000mm. The temperature measurement holes are symmetrically formed on a machine side and a coke side of a coke oven, or are independently formed on single sides of the coke oven such as the machine side or the coke side of the coke oven. Compared with the prior art, the method has the advantages that: the temperature of the bottom of a carbonization chamber of an oven body is measured, so the problem that the measurement of gas temperature is easily affected by factors such as exchange, air pressure, atmospheric temperature and the like is solved, and the correlation of the temperature is improved; meanwhile, temperature measurement components are arranged in the temperature measurement blind holes, so the adverse effect caused by shock, corrosion, cantilever supporting and the like is avoided, and the service life of the temperature measurement components is prolonged.
Description
Technical field
The present invention relates to the coke oven field, relate in particular to a kind of coking furnace shaft chute district continuous temperature measurement hole method of design that is applicable to the different type of furnaces, various coke pushing string preface, different firehole numbers.
Background technology
Coke oven thermometric mode adopts manual thermometric mode and continuous temperature measurement mode at present.The measurement point of standard fire path temperature is located at the flue bottom, and owing to the reason of body of heater and the restriction of temperature instrumentation, the thermometric of this point can only adopt manual intermittent type thermometric.The continuous temperature measurement mode of coke oven mainly is to adopt temperature element to measure the mode of regenerator head temperature at present, adopt the common problem of regenerator top thermometric mode to be: the continuous temperature that measures is except changing with the coking periodic relief, also be minor cycle, little amplitude acute variation with exchange cycle, this gives the disturbance that the judgement of coke oven temperature lifting has been brought certain degree.Its major cause is, what aforesaid method was measured is the temperature of regenerator top gas, and along with the variation of exchange cycle, upstream stage regenerator gas inside is cryogenic air, and downdraft stage regenerator gas inside is a pyritous waste gas; In addition, factors such as vibrations, burn into cantilever support, high temperature accident also exert an influence to the accuracy of temperature data easily.
Summary of the invention
The purpose of this invention is to provide a kind of coking furnace shaft chute district continuous temperature measurement hole method to set up, the temperature point of this method is positioned at two regenerator midfeather tops, on the body of heater in the chute district of coking chamber bottom, the temperature integrated influence of both sides regenerator of this point, air-flow one side that guarantees these both sides is a downdraft, one side is a upstream, and this distance with the temperature point of flue and coking chamber is very near, the temperature data dependency that obtains is good, vulnerability to jamming is strong, this puts comprehensive coke oven regenerator, flue and coking chamber three temperature are the best measuring points of research coking furnace shaft temperature continuous temperature measurement in one.
For achieving the above object, the present invention is achieved through the following technical solutions:
The coking furnace shaft thermometer hole method to set up that a kind of vulnerability to jamming is strong is characterized in that the district is provided with thermometer hole at coke oven chute.
Described thermometer hole is the blind cylindrical hole along coke oven cross wall direction, and the blind hole diameter of section is 20～100mm, and length is 1000～5000mm.
Described thermometer hole adopts coke oven machine side and coke side to be symmetrical arranged, or it is one-sided to be arranged on coke oven separately, as coke oven machine side or coke side.
The distribution of one-sided thermometer hole all has the principle of measuring point in line with the chute zone of the coking chamber below of each coke pushing string preface, the quantity minimum value of one-sided thermometer hole is that (for example: 5-2 string preface radix is 5 to coking technique string preface radix, 2-1 string preface radix is 2), maximum value is the coke furnace carbonization chamber number.
Compared with prior art, the invention has the beneficial effects as follows: because measurement is the temperature in body of heater chute district, be subject to when having avoided the measurement gas temperature to exchange, the problem of factor affecting such as air pressure, free air temperature, improved the dependency of temperature, simultaneously, because temperature element places in the thermometric blind hole, the disadvantageous effect of having avoided vibrations, burn into cantilever support etc. to bring has improved temperature element work-ing life.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
See Fig. 1, continuous temperature measurement hole, coking furnace shaft chute district is applied in the synoptic diagram of pusher side and coke side, and wherein thermometer hole 1 is positioned at coke oven chute district 2, coking chamber 3 bottoms, is provided with in coke oven machine side, coke side zygomorphy.Thermometer hole can be according to the difference of the type of furnace in the position in chute district and corresponding adjustment.
See Fig. 2, thermometer hole 1 is the blind cylindrical hole along coke oven cross wall direction, and the blind hole diameter of section is 20～100mm, and length is 1000～5000mm, and last piece brick that described thermometer hole relates to is not punched.The specification of thermometer hole can adjust accordingly according to the coke oven type of furnace, temperature element specification etc.
It is one-sided that thermometer hole also can be arranged on coke oven separately, and one-sided thermometer hole can be arranged on any side of coke furnace carbonization chamber 3 bottom pusher sides as shown in Figure 1 or coke side.The distribution of one-sided thermometer hole all has the principle of measuring point in line with the chute district, coking chamber below of each coke pushing string preface, the quantity minimum value of one-sided thermometer hole is that (for example: 5-2 string preface radix is 5 to coking technique string preface radix, 2-1 string preface radix is 2), maximum value is the coke furnace carbonization chamber number.The quantity of one-sided thermometer hole can be adjusted according to the type of furnace, performance requriements etc.
This temp measuring method can be suitable for the coke oven of the different type of furnaces, measures the temperature of the coking furnace shaft of various coke pushing string prefaces, different coking chamber quantity.
