Abstract
The invention provides a method for adjusting the suction force of a flue of a coke oven, which comprises the steps of firstly measuring the suction force of a waste gas disk of the coke oven to ensure that the relative value between a measurement number and a standard number is 0Pa, and then fixing a waste gas turning plate of the waste gas disk; detecting the components of the flue waste gas by using flue waste gas analysis equipment, calculating an air excess coefficient, and calibrating an error between the oxygen content in a waste gas analysis result and the oxygen content measured by a flue zirconia oxygen analyzer; adjusting the opening of each exhaust gas disc air valve to enable the air excess coefficient to reach 1.1-1.2, and taking the reading of the zirconia oxygen analyzer at the moment as a reference value for adjusting the suction force of the flue; when the suction force of the flue is adjusted every time, the requirement of a coke oven heating system can be met only by enabling the reading of the zirconia oxygen analyzer to reach the reference value of the zirconia oxygen analyzer. The invention can accurately control the suction force of the flue and improve the thermal efficiency of the coke oven; the blowby of the coke oven is reduced, and the sealing performance of the coke oven body is improved; the phenomenon that the chimney emits black smoke is reduced, and the environmental pollution is avoided.
Description
Technical field
The invention belongs to coking technology field, more particularly to one kind Jiao is carried out using flue zirconia oxygen analyzer
The method of stove flue suction force adjustment.
Background technology
The adjustment of coking coke oven suction not only influences the utilization ratio of coke oven heating coal gas, and influence coke oven charcoal
Change the tightness of room metope.In general production operation, suction adjustment mainly uses empirical method, i.e., according to coal gas
The appropriate increase and decrease flue suction force of regulated quantity, suction regulation is carried out with reference to human body sensory flue thermal current size,
Thus deviation ratio is larger, and flue suction can be excessive or too small, easily causes the excessive (air excess of air capacity
Coefficient is bigger than normal), the thermal efficiency is low, or heating gas incomplete combustion, the phenomenons such as chimney over-emitting black exhaust occurs, very
To carbonization chamber metope blowby is caused, raw coke oven gas enters combustion system, causes chimney over-emitting black exhaust, pollutes environment.
The content of the invention
It is contemplated that accurately controlling flue suction force, the coke oven thermal efficiency is improved, it is to avoid environmental pollution.
Therefore, the technical solution that the present invention is taken is：
A kind of method of adjustment of coke oven flue suction, flue is adjusted according to flue zirconia oxygen analyzer reading
Suction, its specific method is：
(1) coke oven waste gas disk suction is measured, standard No. is close to coke oven middle part and temperature, resistance and sealing
Property relative value i.e. in addition to standard No. between the measurement number of other heat (batch) numbers of a good heat (batch) number and measurement number exist
0Pa, then fixes the waste gas turnover panel of exhaust gas disc；
(2) using stack gases analytical equipment detection stack gases composition, coefficient of excess air is calculated, and mark
Determine the error between the oxygen content of oxygen content and flue the zirconia oxygen analyzer measurement in waste-gas analysis result,
Ensure that zirconia oxygen analyzer measurement is accurate；
(3) each exhaust gas disc throttle opening is adjusted, coefficient of excess air is reached 1.1~1.2, recorded now
Zirconia oxygen analyzer reading, and using the zirconia oxygen analyzer reading as the zirconium oxide of adjustment flue suction force
Oxygen analyzer a reference value；
(4) after hereafter each heated by gas and coal gas plus-minus amount terminate, during adjustment flue suction force, oxygen need to only be made
Change zirconium oxygen analyzer reading and reach zirconia oxygen analyzer a reference value, you can meet the requirement of coke oven heating system.
The zirconia oxygen analyzer a reference value is 2.9~3.1.
Beneficial effects of the present invention are：
The present invention can accurately control flue suction force, improve the coke oven thermal efficiency；Coke oven blowby can be reduced, is improved
The sealing of coking furnace shaft；The phenomenons such as chimney over-emitting black exhaust can effectively be reduced, it is to avoid environmental pollution.
Specific embodiment
The method of adjustment of coke oven flue suction of the present invention, mainly according to flue zirconia oxygen analyzer reading come
Flue suction force is adjusted, its specific method is：
1st, coke oven waste gas disk suction is measured, standard No. is close to coke oven middle part and temperature, resistance and sealing
Then relative value of the good heat (batch) number and measurement number i.e. in addition to standard No. between other heat (batch) numbers will in 0Pa
The waste gas turnover panel of exhaust gas disc is fixed.
2nd, stack gases composition is detected using stack gases analytical equipment, calculates coefficient of excess air, and demarcate
Error between the oxygen content of oxygen content and flue the zirconia oxygen analyzer measurement in waste-gas analysis result, protects
Card zirconia oxygen analyzer measurement is accurate.
3rd, each exhaust gas disc throttle opening is adjusted, coefficient of excess air is reached 1.15, zirconium oxide oxygen now
Analyzer reading be 3.0, and using 3.0 as adjust flue suction force zirconia oxygen analyzer a reference value.
(4) hereafter, after each heated by gas and coal gas plus-minus amount terminate, during adjustment flue suction force, need to only make
Zirconia oxygen analyzer reading reaches 3.0, you can meet the requirement of coke oven heating system, flue suction is neither
Can be excessive, also will not be too small.
When seasonal variations, as long as regulating tuyere aperture, without being analyzed to stack gases.
