Embodiment 1
[0073] Such as figure 2 As shown in , it is a schematic flow chart of the method for predicting the final focal height, including:
[0074] Step 201: Detecting a coke production switching event, and initializing the real-time coke height value of the coke drum ready for coke production when the coke production switching event is detected.
[0075] Step 202: In each preset measurement period, judge whether the real-time coke height of the previous measurement period is less than the transition height of the coke drum, if yes, perform step 203; otherwise, perform step 205.
[0076] Here, the specific time length of the measurement cycle Δt is not limited here, for example, it can be set as: Δt=(1 / 60) hour and so on.
[0077] Such as image 3 As shown, in practical application, each coke tower is at 0~H * The height place is transitioned into cylindrical shape by conical form or billiard table (the embodiment of the present invention is example with conical table) etc., there...
Embodiment 2
[0117] The remaining coke generation time prediction method after the current measurement cycle and figure 2 The method flow shown is similar; however, compared to figure 2 For the prediction of the final focal height shown, in this embodiment, in addition to predicting various parameters of the real-time focal height, it is also combined with the expected focal height H will A prediction of the remaining coking time is performed. and figure 2 The main differences of the illustrated embodiments are:
[0118] In step 204, according to the desired focal height H will , combined with the real-time focal height H of the current measurement cycle i (i=1, 2,...,n), predict the remaining coke-forming time T after the current measurement cycle remain，i .
[0119]
[0120] When predicting the remaining coking time in step 206, the prediction formula can be:
[0121]
[0122] According to the real-time coke height of the current measurement period and the expected coke h...
Embodiment 3
[0124] Schematic diagram of the method for predicting the optimal value of radiant oil feed flow rate and figure 2 The prediction method shown is similar, however, compared to figure 2 For the prediction of the final focal height shown, in this embodiment, in addition to predicting various parameters of the real-time focal height, it is also combined with the expected focal height H will and the expected coking period T will A prediction of the remaining coking time is performed. and figure 2 The main differences of the illustrated embodiments are:
[0125] The expected coke generation period T of the coke drum described in step 204 will and the desired focal height H will , combined with the real-time focal height H of the current measurement cycle i (i=1, 2,..., n), predicting the optimal guidance value F of the radiation oil feed flow corresponding to the current measurement period opt，i .
[0126]
[0127] The optimal value F of the radiation oil feed flow ra...
