[0033] Figure 2 It is a local analysis reference diagram of the present invention. DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figure 1 to Figure 2 As shown, the present invention is an air intake control system for a coke oven carbonization chamber, comprising an air intake control platform, a coke oven database, a pressure supervision and analysis unit, an air intake risk assessment unit, a pressure regulation tracking unit, an obstruction control analysis unit, and a control response unit;

[0036] The coke oven database is connected to the air intake control platform in a one-way communication manner, the air intake control platform is connected to the pressure supervision and analysis unit in a one-way communication manner, the pressure supervision and analysis unit is connected to the air intake risk assessment unit, the pressure regulation tracking unit and the control response unit in a one-way communication manner, the air intake risk assessment unit and the pressure regulation tracking unit are connected to the control response unit in a one-way communication manner, the air intake risk assessment unit and the pressure regulation tracking unit are connected to the obstruction control analysis unit in a one-way communication manner, and the obstruction control analysis unit is connected to the control response unit in a one-way communication manner;

[0037] The air intake control platform retrieves the carbonization chamber pressure data of the coke oven carbonization chamber from the coke oven database, and sends the carbonization chamber pressure data to the pressure supervision and analysis unit. After receiving the carbonization chamber pressure data, the pressure supervision and analysis unit immediately performs pressure balance fluctuation supervision feedback analysis on the carbonization chamber pressure data to determine whether the current pressure of the coke oven carbonization chamber fluctuates within the normal range, so as to timely adjust the air intake of the coke oven carbonization chamber and balance the pressure stability of the coke oven carbonization chamber, which is helpful to improve the working efficiency of the coke oven carbonization chamber. The specific pressure balance fluctuation supervision feedback analysis process is as follows:

[0038] A monitoring period is set and set as a time threshold, the whole coking process in the carbonization chamber of the coke oven is divided into several stages according to the coking time, the coking stage of the carbonization chamber of the coke oven within the time threshold is obtained, and then the carbonization chamber pressure data of the coking stage of the carbonization chamber of the coke oven is obtained, and the carbonization chamber pressure data represents the carbonization chamber pressure value;

[0039] Collecting multiple groups of carbonization chamber pressure data of the same coking stage of the coking chamber ...

[0040] The maximum and minimum values ​​of the carbonization chamber pressure data at the same stage are obtained, and the carbonization chamber pressure range value at each stage is constructed according to the maximum and minimum values ​​of the carbonization chamber pressure data, and the carbonization chamber pressure range value constructed by the maximum and minimum values ​​of the carbonization chamber pressure data is set as the safe pressure area range, thereby obtaining the safe pressure area range at each stage;

[0041] Compare and analyze the carbonization chamber pressure value with the safe pressure range of the same stage:

[0042] If the carbonization chamber pressure value belongs to the safe pressure area range corresponding to the same stage, a stable signal is generated;

[0043] If the carbonization chamber pressure does not fall within the safe pressure region corresponding to the same stage, an adjustment signal is generated;

[0044] The stabilization signal or the adjustment signal is sent to the control response unit. After receiving the stabilization signal or the adjustment signal, the control response unit immediately performs a preset warning operation corresponding to the stabilization signal or the adjustment signal, thereby controlling the carbonization chamber pressure to fluctuate within the safe pressure area to ensure the working efficiency and safety of the carbonization chamber;

[0045] The air intake risk assessment unit is used to respond to the adjustment signal and collect the average working efficiency and energy consumption value of the blower. At the same time, it performs an air intake continuous stability performance safety supervision assessment and analysis to determine whether the blower air intake continuous stability performance is qualified, so as to rationally manage the blower and reduce the impact of the blower on the carbonization chamber pressure adjustment. The specific air intake continuous stability performance safety supervision assessment and analysis process is as follows:

[0046] The time threshold is divided into i sub-time periods, where i is a natural number greater than zero, and the ratio between the mean working efficiency and the energy consumption value of the blower in each sub-time period is obtained. The ratio between the mean working efficiency and the energy consumption value of the blower is set as the performance evaluation index, and the year-on-year growth rate of the performance evaluation index in the next sub-time period relative to the performance evaluation index in the previous sub-time period is obtained. The number of times the year-on-year growth rate falls within the preset year-on-year growth rate range is obtained, and the number of times the year-on-year growth rate falls within the preset year-on-year growth rate range is set as the continuous stable output index, and the continuous stable output index is discriminated:

[0047] If the continuous stable output index is greater than or equal to the preset continuous stable output index threshold, a normal signal is generated;

[0048] If the continuous stable output index is less than the preset continuous stable output index threshold, an interference signal is generated, and the normal signal or the interference signal is sent to the control response unit. After receiving the normal signal or the interference signal, the control response unit immediately displays the preset warning text corresponding to the normal signal or the interference signal, so as to intuitively understand the performance status and output stability of the blower, so as to rationally manage the blower and reduce the influence of the blower on the pressure adjustment of the carbonization chamber;

[0049] In the embodiment of the present invention, the larger the ratio between the average working efficiency and the energy consumption value of the blower is, the more it indirectly indicates that the blower operates with low consumption and high efficiency, which helps to improve the operating stability of the blower.

[0050] Embodiment 2: When a regulation signal is generated, the pressure regulation tracking unit is used to respond to the regulation signal, collect the pressure regulation information of the coke oven carbonization chamber, and perform regulation, supervision, evaluation, feedback and analysis on the pressure regulation information to determine whether the air intake control of the coke oven carbonization chamber is normal, so as to provide timely feedback and early warning, so as to reduce the risk of excessively high or low pressure in the coke oven carbonization chamber, and at the same time help to improve the reliability of air intake management of the coke oven carbonization chamber. The specific regulation, supervision, evaluation, feedback and analysis process is as follows:

[0051] The air intake pressure regulation period of the coke oven carbonization chamber is collected, and the air intake pressure regulation period is divided into g sub-periods, where g is a natural number greater than zero. The pressure regulation information of the coke oven carbonization chamber in each sub-period is obtained. The pressure regulation information includes the pressure change rate and the air intake change amount. The pressure change rate and the air intake change amount are compared and analyzed with the preset pressure change rate range and the preset air intake change amount range:

[0052] If the pressure change rate falls within the preset pressure change rate range, and the intake air change amount falls within the preset intake air change amount range, a normal regulation signal is generated;

[0053] If the pressure change rate does not fall within the preset pressure change rate range, or the intake air change amount does not fall within the preset intake air change amount range, an abnormal regulation signal is generated, the ratio between the number of abnormal regulation signals and the number of normal regulation signals is obtained, and a discriminant analysis is performed on the ratio between the number of abnormal regulation signals and the number of normal regulation signals:

[0054] If the ratio between the number of regulation abnormal signals and the number of regulation normal signals is less than or equal to the preset threshold, no signal is generated;

[0055] If the ratio between the number of corresponding abnormal regulation signals and the number of corresponding normal regulation signals is greater than a preset threshold, an alarm signal is generated and sent to the control response unit. After receiving the alarm signal, the control response unit immediately displays the preset warning text corresponding to the alarm signal, and provides feedback warning according to the feedback information to reduce the risk of excessively high or low pressure in the carbonization chamber of the coke oven, and at the same time helps to improve the reliability of air intake management in the carbonization chamber of the coke oven;

[0056] In the embodiment of the present invention, based on the adjustment signal, the air intake change amount represents the change value corresponding to the air intake amount or the air reduction amount in the sub-time period. It should be noted that the gas floating amount reflects the stability of the air intake control of the carbonization chamber of the coke oven;

[0057] When an alarm signal and a normal signal are generated, the obstruction control analysis unit is used to respond to the alarm signal and the normal signal, collect the control interference information of the coke oven carbonization chamber, and perform obstruction control interference analysis on the control interference information, so as to make reasonable and targeted management adjustments to ensure the stability and reliability of the air intake adjustment of the coke oven carbonization chamber. The specific obstruction control interference analysis process is as follows:

[0058] Obtaining control interference information of the coke oven carbonization chamber, the control interference information including actual valve opening and actual air intake rate characteristic curve;

[0059] The actual valve opening of the coke oven carbonization chamber is obtained, and the set opening of the air inlet valve of the coke oven carbonization chamber is obtained at the same time. The difference between the actual valve opening and the set opening of the air inlet valve is set as the opening deviation value, and the opening deviation value is judged and processed:

[0060] If the opening deviation value is equal to zero, a standard signal is generated;

[0061] If the opening deviation value is not equal to zero, a parameter change signal is generated;

[0062] When the standard signal is generated, the actual air intake rate characteristic curve of the coke oven carbonization chamber is obtained, and the set air intake rate characteristic curve of the coke oven carbonization chamber is obtained at the same time, and then the difference value between the actual air intake rate characteristic curve and the set air intake rate characteristic curve is obtained, and the difference value between the actual air intake rate characteristic curve and the set air intake rate characteristic curve is set as the air intake deviation index, and the air intake deviation index is compared and analyzed:

[0063] If the intake deviation index is greater than a preset intake deviation index threshold, a deviation signal is generated;

[0064] If the intake deviation index is less than or equal to the preset intake deviation index threshold, no signal is generated;

[0065] The parameter change signal or deviation signal is sent to the control response unit. After receiving the parameter change signal or deviation signal, the control response unit immediately displays the preset warning text corresponding to the parameter change signal or deviation signal, so as to make standardized adjustments to the air intake valve or air intake rate according to the intuitive text feedback, so as to ensure the stability of the air intake adjustment process of the entire coke oven carbonization chamber;

[0066] In summary, the present invention analyzes from the perspective of setting the safe range of carbonization chamber pressure, collects the carbonization chamber pressure and determines whether the pressure of the coke oven carbonization chamber fluctuates within the normal range, so as to timely adjust the air intake pressure of the coke oven carbonization chamber, balance the pressure stability of the coke oven carbonization chamber, and help improve the working efficiency of the coke oven carbonization chamber, and further analyzes the continuous stability of the air intake of the carbonization chamber blower, so as to rationally manage the blower and reduce the influence of the blower on the pressure adjustment of the carbonization chamber;

[0067] Under the demand for air pressure regulation in the carbonization chamber of the coke oven, the pressure regulation information is regulated, supervised, evaluated, and feedback analyzed to determine whether the air intake control of the carbonization chamber of the coke oven is normal, so as to provide timely feedback and early warning to reduce the impact of excessive or low pressure in the carbonization chamber of the coke oven. At the same time, it helps to improve the reliability of air intake management in the carbonization chamber of the coke oven. Under the premise of abnormal pressure regulation, the control interference information is hindered, regulated, and interfered with by analysis, so as to make reasonable and targeted management adjustments to the factors hindering the air pressure regulation and ensure the stability of the entire air intake adjustment process in the carbonization chamber of the coke oven.

[0068] The threshold is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by technicians in this field for each group of sample data; as long as it does not affect the proportional relationship between the parameter and the quantized value.

[0069] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
