Advantages and features of the invention will become more apparent from the following description and from the claims.
The embodiment of the invention provides a method for acquiring the standard temperature of a carbonization chamber of a coke oven, which simulates the dynamic change of the temperature in the combustion process of a coke oven body into a dynamic temperature target, is different from other schemes for fixing the temperature target, and is more accurate, energy-saving and efficient. The method for calculating the fitted temperature of the coke oven analyzes various fault factors of the acquired signals, counts the number of normal and fault signals into temperature statistics, and allows a plurality of temperature points in the same serial sequence to have higher fault tolerance according to the temperature statistics method of the coal charging serial sequence of the coke oven; according to the direction of the flame path air flow, a relatively stable interval after the direction change is selected for calculation, so that disturbance generated by the direction change of the coke oven can be eliminated, and the method is more accurate than other schemes; meanwhile, the real-time monitoring of the temperature measuring element is higher than the real-time performance of manual temperature measurement and is more reliable.
Referring to fig. 1, the method for obtaining the standard temperature of the carbonization chamber of the coke oven comprises the following steps:
s1: arranging a coding cable in the carbonization chamber of the coke oven, and arranging a recognizable carbonization chamber number on the coding cable;
s2: the method comprises the steps that a data acquisition device is arranged on a coal charging car or a coke pushing car, and the data acquisition device is used for acquiring the serial numbers of carbonization chambers, coal charging action signals and coke pushing action signal data of the coal charging car or the coke pushing car and transmitting the acquired data to a control device;
s3: the control device calculates coking time according to the carbonization chamber number, the coal loading action signal and the coke pushing action signal data;
s4: and fitting a standard carbonization chamber temperature curve through a multi-order Gaussian function according to the coking time to obtain the standard temperature of the carbonization chamber of the coke oven.
Specifically, the standard temperature of the single carbonization chamber is calculated by mathematical modeling, and the standard temperature of the carbonization chamber corresponding to the current coking time is used as the standard temperature of the current carbonization chamber after manual correction. Coking time (x) measurement of carbonization chamber: starting from coal charging to coke pushing.

2) Accurately positioning the carbonization chamber number of coal charging at the current moment or the carbonization chamber number of coke pushing at the current moment through a coding cable;
3) Is transmitted to the APC computer control system of the control room by wireless. The APC computer control system calculates the time used in the whole coking process, namely coking time (x), according to the number of the carbonization chamber and in combination with the coal charging and coke pushing actions of the carbonization chamber.
The standard temperature of the whole furnace is calculated by combining the standard temperature average of each carbonization chamber, and the temperature curves of the side furnace and other carbonization chambers are completely different, so that mathematical model calculation is carried out on the temperatures of the side furnace and the other carbonization chambers separately, and the standard carbonization chamber temperature curves of the laboratory are fitted through a multi-order Gaussian function by Matlab software, so that a final fitting formula is obtained. Different furnace types can be fitted with different formula coefficients according to experimental data, and a stamp-charging coke oven of 5.5 meters is taken as an example:
1) Standard carbonization chamber temperature (y):
y＝a1*EXP(-((x-b1)/c1)*((x-b1)/c1))+a2*EXP(-(((x-b2)/c2)*(x-b2)/c2))+
a3*EXP(-(((x-b3)/c3)*(x-b3)/c3))+a4*EXP(-(((x-b4)/c4)*(x-b4)/c4))；

2) Side furnace carbonization chamber temperature (y):
Y＝a11*EXP(-((x-b11)/c11)*((x-b11)/c11))+a12*EXP(-(((x-b12)/c12)*(x-b1
2)/c12))+a13*EXP(-(((x-b13)/c13)*(x-b13)/c13))+a14*EXP(-(((x-b14)/c14)*(x-b14)/c14))；

TV＝y+JZWD；
JZWD, manually correcting temperature;
4) The standard Temperature (TSV) of the carbonization chamber of the whole furnace is calculated by average calculation from the standard temperature of each carbonization chamber. As a setting value for the compensation adjustment, a single furnace 72 hole is taken as an example:
TSV＝(TV1+TV2+……TV71+TV72)/72。
the fitting temperature TSP of the carbonization chamber of the whole furnace, namely the temperature of the coke oven, is a main control object in a temperature control system of the coke oven. The final mathematical function is formed by analyzing factors such as ascending and descending flame paths of the coke oven, coal charging serial sequences, coke oven reversing and the like.
1) Judging the direction of the flame path air flow: and after reversing, the temperature of the carbonization chamber is acquired at intervals of 30S, the acquired data is stored in a system cache variable area, the temperature trend is judged after the continuous judgment for 3 minutes, when the detected temperature continuously drops and the total drop amplitude is larger than the judgment amplitude (default 5 degrees), the flame path can be considered to be in a falling flame path, otherwise, if the temperature continuously rises, the flame path is judged to be a rising flame path.
2) Quality analysis is carried out on the temperature acquisition signals, and the allowable upper limit and the allowable lower limit of the temperature and the maximum change rate are regulated according to the process requirements; diagnosing abnormal phenomena such as circuit breaking, short circuit, temperature mutation and the like, and alarming and reminding abnormal temperature. The quality (DQ) output is 1 when the temperature is normal, and 0 when the temperature is abnormal; and counting the number of the normal faults and the number of the faults of the temperature acquisition equipment in a serial mode. Taking the serial sequence of the coal-charging 92 serial sequence 1# group as an example, the effective temperature number of the 1# group is as follows:
DQ＝DQ1+DQ11+DQ21+DQ31+DQ41+DQ51+DQ61+DQ71+DQ81。
3) Summarizing the temperature signals according to the coal loading serial sequence, and calculating the serial sequence fitting temperature:
TE1＝T1*DQ1+T11*DQ11+T21*DQ21+T31*DQ31+T41*DQ41+……T81*DQ81。
temperature of the whole furnace:
TS＝average(TE1:TE8).
4) And selecting the calculated temperature of the whole furnace, and selecting the temperature after 5-10 minutes of reversing of the descending flame path as the fitting temperature TSP of the whole furnace. The selection of the commutation time can be selected based on the actual temperature profile of the coke oven.
5) Program code:
IF JL1AVG1100>JL1AVG100 THEN
jl1_ud =true; side downdraft flag
ELSE
Jl1_ud =false; side updraft flag
END_IF；
IF JL1_TIMER>＝300AND JL1_UD＝TRUE THEN TSP:＝JL1_AVG；END_IF；
And (3) compensating and controlling the moisture, the gas heat value, the gas flow, the ambient temperature and the coal loading amount of the coal, and forming a broken line function to carry out correction and compensation according to the influence of each factor on the temperature.
Referring to fig. 2, the standard temperature TSV is taken as a set temperature, the fitting temperature TSP is taken as an adjustment object, the temperature compensation is converted from the moisture content, the gas heat value, the gas flow, the ambient temperature and the coal loading amount of the coal, the temperature compensation is adjusted, the pressure increment of the return gas is output, and the return gas pressure adjustment system is compensated in real time.
