Description

Technical Field

[0001] The present invention relates to the technical field of process industry, and specifically provides a rapid in-situ liquid shunt distribution system and a distribution method thereof. Background Art

[0002] The process industry, also known as the process manufacturing industry, refers to the production process carried out through physical changes, chemical changes, or a combination of the two. Its raw materials and products are mostly homogeneous-phase (solid, liquid, or gas) materials, rather than items assembled from parts. Industries such as chemical engineering, oil refining, metallurgy, light industry, building materials, and pharmaceuticals are all involved in the process industry. Since the process industry mainly creates value from raw materials through mixing and forming or chemical reactions, such as the production processes of drugs, chemicals, and food and beverages, there are inevitably a large number of physical and chemical changes in the processing process of process manufacturing. With the digital transformation of process industry processing and production, when processing homogeneous-phase materials, higher requirements are put forward for the accuracy of liquid shunt distribution.

[0003] However, in the multi-reaction process of the process industry, there are generally phenomena such as fast reaction speed, many types of reactants, and coexistence of gas, solid, and liquid. Moreover, there are significant differences in the characteristics of liquids such as concentration, temperature, salinity, and viscosity in different reaction units.

[0004] Although existing liquid sample collection systems can continuously sample samples, they can only transport liquids under preset distribution flow control and cannot adjust the shunt ratio of the required flow between modules in real time according to the actual flow requirements of the distribution module, making it difficult to meet the long-distance liquid supply requirements. On the other hand, the chemical reaction speed involved in the process industry is relatively fast, making the physical and chemical properties of the sampled materials prone to change. If the timeliness of liquid distribution cannot be ensured, the materials with changed properties will have an adverse impact on the detection results and affect the accuracy of the detection results. Therefore, we propose a rapid in-situ liquid shunt distribution system and a distribution method thereof that can adjust the shunt ratio of the required flow between modules in real time and improve the accuracy of detection results. Summary of the Invention

[0005] The purpose of the present invention is to provide a rapid in-situ liquid shunt distribution system and a distribution method thereof to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] On the one hand, a rapid in-situ liquid shunt distribution system is provided, including a PLC input-output control module, a sample continuous collection module, a liquid shunt distribution module, an in-situ real-time monitoring module, a liquid confluence and reuse module, a reaction unit group, and an overflow channel;

[0008] The PLC distribution control module, the sample continuous acquisition module, the liquid shunt distribution module, the original sample real-time monitoring module, and the liquid confluence recycling module all include at least one signal transceiver;

[0009] The PLC distribution control module implements closed-loop control over the liquid shunt distribution, and dynamically adjusts the liquid distribution time, flow rate, and flow velocity. The output end of the PLC distribution control module is electrically connected to the sample continuous acquisition module, the liquid shunt distribution module, the original sample real-time monitoring module, and the liquid confluence recycling module respectively. The PLC distribution control module sends control instructions to the sample continuous acquisition module, the liquid shunt distribution module, the original sample real-time monitoring module, and the liquid confluence recycling module respectively;

[0010] The original liquid can be one or a combination of several of domestic water, sewage, industrial water, or reaction liquid in industry;

[0011] The upstream pipeline of the sample continuous acquisition module is connected to a reaction unit group, and the downstream pipeline of the reaction unit group is connected to the liquid confluence recycling module. The sample continuous acquisition module dynamically adjusts the total amount of samples collected by receiving the distribution control instructions of the PLC distribution control module to meet the overall time length and total liquid consumption of the system liquid distribution;

[0012] The upstream of the liquid shunt distribution module is connected to the sample continuous acquisition module through a pipeline, and the downstream pipeline of the liquid shunt distribution module is connected to the original sample real-time monitoring module; the liquid shunt distribution module dynamically adjusts the liquid inlet flow rate of the original sample real-time monitoring module by receiving the distribution control instructions from the PLC distribution control module;

[0013] The original sample real-time monitoring module detects and analyzes the spectral signal-to-noise ratio of the liquid sample in the reaction unit group, and sends the signal-to-noise ratio detection result to the PLC distribution control module in the form of positive feedback or negative feedback to dynamically adjust and adapt the liquid inlet flow rate and flow velocity of the original sample real-time monitoring module;

[0014] The liquid confluence recycling module monitors the reflux liquid and transports the reflux liquid to the appropriate reaction unit in the reaction unit group for the separation and recycling of the reflux liquid according to its quality.

[0015] As a further solution of the present invention: the reaction unit group includes several sub-reaction units connected in parallel, the conveying pipelines respectively connected to adjacent sub-reaction units are independent and parallel to each other, several sub-reaction units are respectively connected between the sample continuous acquisition module and the liquid confluence recycling module, and the concentrations, temperatures, salinities, and viscosities of the liquid samples loaded in different sub-reaction units are not completely the same.

[0016] As a further solution of the present invention: the concentrations, temperatures, salinities, and viscosities of the liquid samples loaded in different sub-reaction units are completely different.

[0017] As a further solution of the present invention: The reaction unit group includes a first reaction unit, a second reaction unit and a third reaction unit, and the first reaction unit, the second reaction unit and the third reaction unit are all liquid reaction vessels.

[0018] As a further solution of the present invention: The sample continuous acquisition module continuously acquires the liquid samples loaded in the first reaction unit, the second reaction unit and the third reaction unit, and transports the acquired liquid samples to the liquid shunt distribution module. The sample continuous acquisition module adjusts the acquisition flow rate and flow velocity of the liquid according to the control instructions sent by the PLC distribution control module.

[0019] As a further solution of the present invention: The system further includes an overflow channel, which is connected between the liquid shunt distribution module and the liquid confluence recycling module. The overflow channel converges the excessive liquid distributed by the liquid shunt distribution module to the original sample real-time monitoring module into the liquid confluence recycling module; the connection between the overflow channel and the liquid shunt distribution module forms an overflow port, and the excessive liquid enters the overflow channel through the overflow port and is transported to the liquid confluence recycling module by the corresponding overflow channel, so as to adjust the flow rate of the liquid entering the original sample real-time monitoring module.

[0020] As a further solution of the present invention: The liquid confluence recycling module includes a signal transceiver and a liquid pump. The signal transceiver receives the mass separation control instruction from the PLC distribution control module, and the liquid pump serves as a mass separation pump to transport the excessive liquid to the adapted sub-reaction unit. By actively pumping out the liquid with a mass separation pump, it can ensure that the sub-reaction unit receives the confluent liquid passively.

[0021] On the other hand, a fast original sample liquid shunt distribution method is also provided, which is applied to the distribution system and includes the following steps:

[0022] S1: Dynamically adjust the suction flow rate Q and flow velocity V of the liquid in different reaction units according to the transport distance L and the cross-sectional area S of the pipeline,

[0023] The distribution time t = the distribution distance L ÷ the flow velocity V;

[0024] The flow velocity V = the flow rate Q ÷ the cross-sectional area S of the pipeline;

[0025] S2: Calculate the flow velocity V according to the distribution time t and the transport distance L:

[0026] t (min) = L (m) ÷ V (m / min) ≤ 1 min → V (m / min);

[0027] S3: Calculate the flow rate Q according to the transport flow velocity V and the cross-sectional area S of the pipeline:

[0028] V (m / min) = Q (ml / min) ÷ S (mm 2 ) → Q (ml / min), to determine the flow rate Q (ml / min) and flow velocity V (m / min) for dynamic continuous collection and distribution in different reaction units; where

[0029] The distribution distance can be measured on-site, the flow rate can be directly adjusted and controlled on-site, and the flow velocity is the result of calculation;

[0030] S4: According to the spectral signals of the liquids in different reaction units monitored under static conditions, obtain the absorbance intensity and noise fluctuations corresponding to the liquid concentrations in different reaction units under static conditions;

[0031] During monitoring, following the principle that the similarity under dynamic and static noise conditions is ≥ 99%, monitor the spectral signals of different concentration species under static and dynamic conditions respectively. The spectral signal is the Abs value signal corresponding to each wavelength condition in the wavelength range of 180 nm - 900 nm of the monitored liquid sample. The original sample real-time monitoring device is used to monitor the spectral signal;

[0032] According to the standard preset values of the flow rate and flow velocity of the PLC distribution control module, the PLC distribution control module automatically matches the optimal flow rate and flow velocity of the incoming liquid. The liquid flow rate is suctioned by negative pressure of a peristaltic pump, and the size of the liquid flow rate can be adjusted by adjusting the rotation speed of the peristaltic pump;

[0033] The calculation formula for the flow velocity is: flow velocity = flow rate ÷ pipe diameter. On the premise that the pipe diameter remains unchanged, the size of the flow velocity is determined by the size of the flow rate. The flow velocity has a greater impact on the disturbance of the sample in the flow-through cell of the original sample real-time monitoring module. When the flow velocity is too small, the sample is prone to form a flow field dead zone in the cell, affecting the detection sensitivity. When the flow velocity is too large, the sample noise has a greater impact on the signal. Therefore, it is necessary to detect the spectral signals of different concentration samples under static conditions, then compare the spectral signals under different incoming liquid flow velocity conditions with the corresponding static ones, and select the incoming liquid flow velocity corresponding to the spectrum with the highest coincidence degree and the smallest noise to determine the corresponding optimal optimal flow rate;

[0034] S5: Dynamically monitor the spectral signals of the target liquid under different flow rate and flow velocity incoming liquid conditions, and obtain the absorbance intensity and noise fluctuations corresponding to the target liquid with different concentrations under dynamic conditions.

[0035] As a further solution of the present invention: In the step S2, the total time t from sample sampling to confluence and return distribution ≤ 1 min.

[0036] As a further solution of the present invention: Under static conditions, the liquid concentrations in different reaction units are C1, C2,... C n ;

[0037] The absorbance intensities corresponding to the liquid concentrations in the different reaction units are Ia1, Ia2, …… Ia n ;

[0038] The noise fluctuations corresponding to the liquid concentrations in the different reaction units are ΔIa1, ΔIa2, …… ΔIa n 。

[0039] As a further solution of the present invention: Under dynamic conditions, the liquid concentrations in the different reaction units are C1’, C2’, …… C n ’;

[0040] The absorbance intensities corresponding to the liquids in the different reaction units are Ia1’, Ia2’, …… Ia n ’;

[0041] The noise fluctuations corresponding to the liquids in the different reaction units are ΔIa1’, ΔIa2’, …… ΔIa n ’。

[0042] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0043] By means of the original sample real-time monitoring module, the present invention detects the spectral signals of samples with different concentrations under static conditions, can compare the spectral signals under static conditions under different liquid inlet flow rate conditions, quickly selects the liquid inlet flow rate corresponding to the spectrum with the highest coincidence degree and the smallest noise, so that the PLC input and distribution control module 1 determines the optimal flow rate and flow velocity of the liquid flowing through the corresponding module, realizes the real-time dynamic adjustment of the flow rate and flow velocity of the liquid sample in the distribution system, meets the liquid supply demand over a long distance, and at the same time can ensure the timeliness of liquid distribution, avoid the adverse impact of materials with changed properties on the detection results, and is beneficial to improving the accuracy of the detection results of liquid materials.

[0053] The original sample real-time monitoring module 4 detects and analyzes the spectral signal-to-noise ratio of the liquid sample in the reaction unit group 6, and sends the signal-to-noise ratio detection result to the PLC distribution control module 1 in the form of positive feedback or negative feedback to dynamically adjust the liquid inlet flow rate and flow velocity suitable for the original sample real-time monitoring module 4.

[0054] The liquid confluence and reuse module 5 monitors the reflux liquid and transports the reflux liquid to the appropriate reaction unit in the reaction unit group 6 for the separation and recycling of the reflux liquid.

[0055] Preferably, the reaction unit group 6 includes a plurality of sub-reaction units connected in parallel. The conveying pipelines respectively connected to adjacent sub-reaction units are independent and parallel to each other. A plurality of sub-reaction units are respectively connected between the sample continuous collection module 2 and the liquid confluence and reuse module 5.

[0058] Example 2:

[0059] The difference from the above embodiment is:

[0060] The concentrations, temperatures, salinities, and viscosities of the liquid samples loaded in different sub-reaction units are completely different.

[0061] The reaction unit group 6 includes a first reaction unit 61, a second reaction unit 62, and a third reaction unit 63. The first reaction unit 61, the second reaction unit 62, and the third reaction unit 63 are all liquid reaction vessels. The first reaction unit 61, the second reaction unit 62, and the third reaction unit 63 are respectively connected between the sample continuous collection module 2 and the liquid confluence and reuse module 5 through independent pipelines.

[0062] Preferably, the sample continuous collection module 2 continuously collects the liquid samples loaded in the first reaction unit 61, the second reaction unit 62, and the third reaction unit 63, and transports the collected liquid samples to the liquid shunt distribution module 3. The sample continuous collection module 2 adjusts the collection flow rate and flow velocity of the liquid according to the control instructions sent by the PLC distribution control module 1.

[0063] When shunting and distributing the liquid samples:

[0064] First, according to the transportation distance L and the cross-sectional area S of the pipeline, dynamically adjust the suction flow rate Q and flow velocity V of the liquids in different reaction units.

[0065] The distribution time t = transportation distance L ÷ flow velocity V;

[0066] The flow velocity V = flow rate Q ÷ cross-sectional area S of the pipeline;

[0067] Second, calculate the flow velocity V based on the distribution time t and the transportation distance L:

[0068] t (min) = L (m) ÷ V (m / min) ≤ 1 min → V (m / min);

[0069] Calculate the flow rate Q based on the transportation flow velocity V and the cross-sectional area S of the pipeline:

[0070] V (m / min) = Q (ml / min) ÷ S (mm 2 ) → Q (ml / min), and determine the flow rate Q (ml / min) and flow velocity V (m / min) for dynamic continuous collection and distribution of different reaction units; where

[0071] The transportation distance can be measured on-site, the flow rate can be directly adjusted and controlled on-site, and the flow velocity is the calculated result;

[0072] Third, according to monitoring the spectral signals of the liquids in different reaction units under static conditions, obtain the absorbance intensity and noise fluctuations corresponding to the liquid concentrations in different reaction units under static conditions;

[0073] Finally, dynamically monitor the spectral signals of the target liquid under the conditions of liquid inlet with different flow rates and flow velocities, and obtain the absorbance intensity and noise fluctuations corresponding to the target liquid with different concentrations under dynamic conditions.

[0074] Preferably, in step S2, the total time t from sample sampling to confluence return and distribution is t ≤ 1 min.

[0075] Preferably, under static conditions, the liquid concentrations in different reaction units are C1, C2, …… C n ;

[0079] The absorbance intensities corresponding to the liquids in different reaction units are Ia1’, Ia2’, …… Ia n ’;

[0080] The noise fluctuations corresponding to the liquids in different reaction units are ΔIa1’, ΔIa2’, …… ΔIa n ’.

[0081] During monitoring, following the principle that the similarity under dynamic and static noise conditions is ≥ 99%, the spectral signals of different concentration species under static and dynamic conditions are monitored respectively. The spectral signal is the Abs value signal of the absorbance intensity corresponding to each wavelength condition within the wavelength range of 180 nm - 900 nm for the monitored liquid sample. The device used for monitoring the spectral signal is the original sample real-time monitoring device;

[0082] According to the preset flow rate and flow velocity standards of the PLC distribution control module 1, the PLC distribution control module 1 automatically matches the optimal flow rate and flow velocity of the incoming liquid. The liquid flow rate is suctioned by negative pressure of a peristaltic pump, and the size of the liquid flow rate can be adjusted by adjusting the rotational speed of the peristaltic pump;

[0083] The calculation formula for the flow velocity is: flow velocity = flow rate ÷ pipe diameter. On the premise that the pipe diameter remains unchanged, the size of the flow velocity is determined by the size of the flow rate. The flow velocity has a greater impact on the disturbance of the sample in the flow cell of the original sample real-time monitoring module 4. When the flow velocity is too small, the sample is prone to form a dead zone in the cell, affecting the detection sensitivity. When the flow velocity is too large, the sample noise has a greater impact on the signal. Therefore, it is necessary to detect the spectral signals of different concentration samples under static conditions, then compare the spectral signals under different incoming liquid flow velocity conditions and compare them with the corresponding static conditions, and select the incoming liquid flow velocity corresponding to the spectrum with the highest coincidence degree and the smallest noise to determine the corresponding optimal optimal flow rate;

[0084] This application detects the spectral signals of samples with different concentrations under static conditions through the in-situ real-time monitoring module 4, and can compare the spectral signals under static conditions under different liquid inlet flow rate conditions, quickly select the liquid inlet flow rate corresponding to the spectrum with the highest coincidence degree and the least noise, so that the PLC input and distribution control module 1 can determine the optimal flow rate and flow velocity of the liquid flowing through the corresponding module, realize the real-time dynamic adjustment of the flow rate and flow velocity of the liquid sample in the distribution system, meet the liquid supply requirements for long distances, and at the same time ensure the timeliness of liquid distribution, avoid the adverse impact of materials with changed properties on the detection results, and is conducive to improving the accuracy of the detection results of liquid materials.
