The following detailed description of exemplary embodiments of the disclosure refers to the accompanying drawings.
FIG. 1 is a flow chart of a method of design of an extraction tank fining chamber in an exemplary embodiment of the present disclosure. Referring to fig. 1, an extraction tank fining chamber design method 100 may include:
step S102, acquiring the extraction process type and the processing capacity input by a user;
step S104, determining process parameters and influence coefficients of the process parameters according to the types of the extraction processes;
step S106, determining the area design value of the clarification chamber according to the treatment capacity;
step S108, determining the minimum length of the clarifying chamber according to the process parameters and the influence coefficients of the process parameters;
and step S110, determining a length design value and a width design value of the clarification chamber according to the area design value, the minimum length and the preset aspect ratio constraint value.
According to the embodiment of the disclosure, the area design value and the minimum length of the clarifying chamber are determined according to the extraction process and the treatment capacity selected by a user, and then the length design value and the width design value of the clarifying chamber are determined, so that the size of the clarifying chamber with a better application effect can be rapidly designed, and the design efficiency and the design effect of the clarifying chamber of the extraction tank are effectively improved.
The method 100 provided by the embodiment of the present disclosure may be executed by a data processing model, which is trained to embed various preset values and preset corresponding relationships, so as to implement data classification and data operation functions.
The steps of the method 100 for performing an extraction tank fining chamber design using a data processing model are described in detail below.
In step S102, the extraction process type and the processing amount input by the user are acquired.
The extraction process category may include, for example, simple molecular extraction, neutral complex extraction, acidic complex extraction, ion association extraction, synergistic extraction, etc., and the disclosure is not particularly limited thereto. The processing amount can be determined by the user according to the use requirement.
In step S104, the process parameters and the influence coefficients of the process parameters are determined according to the types of the extraction processes.
In the embodiment of the present disclosure, the process parameters may include, for example, an oil phase inlet flow rate, an oil phase viscosity, an extraction tank mixing chamber stirring strength, and an oil-water ratio, where the process parameters are related to an extraction process type, a default recommended value may be generated by the system according to the extraction process type, and the recommended value may also be modified by a user according to actual needs. In the embodiment of the present disclosure, the trained data processing model is used to generate the default recommended values of the process parameters corresponding to the process types, and the form of the data model can be referred to as the following formula (2).
In step S106, the area design value of the fining chamber is determined based on the throughput.
The treatment amount, i.e., the treatment flow rate or the treatment speed, may be the sum of the water phase carry-in flow rate and the oil phase carry-in flow rate, and may be, for example, L/h (liter/hour) or L/min (liter/minute). The area design value can be determined according to the ratio of the treatment capacity to the preset clarification rate, and specifically can be as follows:
S＝Vz/Vc (1)
wherein S is an area design value, vz is a treatment capacity, and Vc is a preset clarification rate. The preset clarification rate can be set empirically by one skilled in the art.
In step S108, the minimum length of the fining chamber is determined based on the process parameter and the coefficient of influence of the process parameter.
In an embodiment of the present disclosure, the minimum length may be determined according to the following equation (2):
wherein L is min Is a minimum length, x 1 ～x 4 N, m, z and l are influence coefficients of each process parameter respectively, and A and D are model selection coefficients.
In the embodiment of the present disclosure, the influence coefficients of the above formula (2) and each process parameter in the formula (2) are determined in advance through fluid mechanics simulation calculation results under orthogonal experiments. Specifically, the relationship between the minimum length capable of optimizing the use effect parameter and the influence coefficient of the process parameter and the process parameter can be determined by judging the existence length and depth of the mixed phase and the purity of the outlet product. For each extraction process, the recommended values of the process parameters, the influence coefficients of the process parameters and the model selection coefficients a and D can be determined by formula (2), and the recommended values of the process parameters, the influence coefficients of the process parameters and the combination of the model selection coefficients a and D can obtain the minimum length of the clarifying chamber with the best extraction effect (for example, 100% separation of water and oil phases) under the extraction process.
For each extraction process, the influence coefficient and the model selection coefficient of the corresponding process parameter are set, and after the user selects the extraction process, the value of each process parameter can be modified according to the requirement, but the values of the influence coefficient and the model selection coefficient cannot be modified.
The using effect parameters of the extraction tank can comprise a water-oil phase separation effect value, a clarification rate value, a light-heavy liquid flow fluctuation value, an outlet entrainment value, an extraction phase continuity value and the like. The influence coefficient of each process parameter affecting the effect parameter, specifically, the influence coefficient of each process parameter that optimizes the value of the effect parameter, may be determined by fluid mechanics simulation calculation under an orthogonal experiment. The influence coefficients of the process parameters may include, for example: the flow rate influence coefficient, the viscosity influence coefficient, the stirring strength influence coefficient and the comparison influence coefficient are in one-to-one correspondence with the types of the process parameters.
In the embodiment of the disclosure, through a large number of simulation calculation analyses, the main influencing factors influencing the two-phase separation effect of the clarifying chamber of the extraction tank, namely, the process parameters corresponding to the extraction process types are determined. On the basis, the influence coefficient of each process parameter is determined by carrying out a large number of orthogonal experiments. Next, a preset mathematical model may be used to determine the minimum length of the fining chamber that will optimize the performance parameters based on the process parameters and the coefficients of influence of the process parameters.
In step S110, the length design value and the width design value of the fining chamber are determined from the area design value, the minimum length, and the preset aspect ratio constraint value.
At this step, the maximum width of the fining chamber may be determined first based on the area design value and the minimum length, and then the length design value and the width design value may be determined based on the maximum width, the minimum length, and the preset aspect ratio constraint value.
It is understood that, in this step, since the maximum width, the minimum length, and the aspect ratio constraint values used in the calculation are all directed to the uncertain length value and width value, the determined length design value and width design value are not necessarily unique, and there may be a plurality of pairs of the length design value and width design value that meet the length requirement, width requirement, and aspect ratio requirement.
In order to select the most suitable combination pair of the length design value and the width design value, in the embodiment of the present disclosure, a verification method as shown in fig. 2 may also be adopted to select the optimal design value.
FIG. 2 is a flowchart of a method for selecting an optimal design value in a loop in an embodiment of the disclosure.
Referring to fig. 2, step S110 may include:
step S1102, determining a plurality of combination pairs of a design value for length and a design value for width that meet a minimum length, a preset aspect ratio, and an area design value;
step S1104, determining a corresponding effect parameter group of each combination pair according to the length design value of each combination pair, the process parameters and the influence coefficients of the process parameters;
in step S1106, the combination pair corresponding to the optimal effect parameter group is determined as the length design value and the width design value.
Through the verification method shown in fig. 3, a combination pair which can optimize the design effect can be selected from a plurality of combination pairs of the required length design value and width design value, and then the optimal design value of the size of the clarification chamber is output.
The data processing model provided by the embodiment of the disclosure can be used for generating a clarification chamber size design value, and can also be used for outputting an effect parameter group according to a length design value input by a user, namely, the application effect prediction of different extraction tank design sizes is realized.
In addition to outputting the length design value and the width design value, the disclosed embodiments may further determine a depth design value. The design value of the depth of the clarifying chamber can be determined according to the type of the extraction process, and different types of the extraction process can be set to correspond to different design values of the depth according to experience.
In the design process of the clarifying chamber, whether a grid plate is added or not can be determined to ensure that the water phase and the oil phase are fully separated in the clarifying chamber, and the oil-in-water impurity entrainment at a water phase outlet and the water-in-oil impurity entrainment at an oil phase outlet are avoided.
FIG. 3 is a flow chart of determining whether to add a louver in another embodiment of the present disclosure.
Referring to fig. 3, in one embodiment of the present disclosure, the extraction tank fining chamber design method may further comprise:
step S112, determining the length-width ratio according to the length design value and the width design value;
and step S114, determining to add a grid plate to the clarification chamber when the aspect ratio exceeds a preset value.
Specifically, if the aspect ratio is greater than 1, a grid needs to be added. The preset value can be set by a person skilled in the art according to the working condition, and the disclosure is not limited thereto.
Through the process, the design method of the clarifying chamber of the extraction box, which is provided by the disclosure, can directly output the length design value, the width design value, the depth design value and the grid plate adding scheme of the clarifying chamber of the extraction box, which can enable the effect parameter value to be optimal, according to the extraction process type and the treatment capacity selected by a user, greatly improves the design efficiency and the design effect of the clarifying chamber, can design the clarifying chamber which can ensure the sufficient separation of water phase and oil phase in the clarifying chamber and avoid the oil-in-water impurity entrainment at the water phase outlet and the oil phase outlet.
In addition, by using the data processing model developed by the extraction tank clarification chamber design method disclosed by the disclosure, the operation effect parameter set of the clarification chamber can be output according to the length design value input by a user, so that the application effects of different extraction tank design sizes can be predicted.
Corresponding to the above method embodiments, the present disclosure also provides an extraction tank fining chamber design system, which can be used to perform the above method embodiments.
