[0025] In order to make the above-mentioned purposes, features and advantages of the present application more apparent, obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0026] Please refer to Figure 1The embodiment provides a corrosion inhibitor blending production line, which comprises raw material conveying lines and a reaction line in communication, and the number of the raw material conveying lines is at least two; the raw material conveying line is provided with a raw material storage tank 9 and a conveying pump 8 connected by pipelines in sequence, and is further provided with a sensing element 7 for monitoring raw material flow; the reaction line is provided with a static mixing device 10, a stirring device 4 and a finished product buffer tank 3 connected by pipelines in sequence.

[0027] The working principle of the embodiment is as follows:

[0028] During the liquid conveying process, the sensing element 7 for monitoring raw material flow collects real-time flow information of the raw material and transmits the data to a control system of the production line; the control system adds the raw material required for corrosion inhibitor production into the production system through the conveying pump 8 according to the set production data, and stops the conveying when the conveying amount of the raw material reaches the set value.

[0029] After the raw material in the at least two raw material conveying lines is sent into the reaction line, the raw material is first subjected to static mixing in the static mixing device 10 and then is subjected to dynamic mixing in the stirring device 4, so that the various raw materials are uniformly dispersed, and then the raw material is subjected to reaction and enters the finished product buffer tank 3 after the reaction is completed, thereby completing the production of the corrosion inhibitor.

[0030] The static mixing device 10, the conveying pump 8 and the pipelines are all made of stainless steel, which can effectively prevent material corrosion. The stirring device 4 is a shearing type stirrer, which can make the raw material mixing more uniform and faster.

[0031] The sensing element 7 for monitoring raw material flow is arranged on the raw material conveying line, and the start and stop of the conveying pump 8 can be controlled by the control system according to the detected flow data during the raw material conveying process. Compared with manual metering, the sensing element 7 for monitoring raw material flow has high accuracy, small error and high efficiency, and can effectively ensure the stability of production and the quality of products.

[0032] Specifically, the sensing element 7 can be a mass flowmeter, which can directly measure the mass flow of fluid and can measure the density and temperature of the medium. The working process of the mass flowmeter includes the following steps: first, the excitation voltage provided by the transmitter is added to the driving coil, so that the vibration tube reciprocatingly vibrates. When the fluid medium flows through the vibration tube of the sensor, the Coriolis force effect is generated, which causes the vibration tube to torsionally vibrate. The detection coils installed at both ends of the vibration tube detect signals with different phases, and the phase difference of the signals is proportional to the mass flow of the fluid flowing through the sensor. The computer can obtain the mass flow, density and temperature of the fluid flowing through the vibration tube by calculating the signals.

[0033] The working principle of a mass flow meter is based on the Coriolis effect. When a fluid flows in a rotating pipe, a force related to the mass of the fluid is generated, which is called the Coriolis force. Mass flow meters use this effect to measure the mass flow of a fluid. Specifically, a mass flow meter is usually composed of a vibrating pipe, a signal detector, a vibration driver, a support structure, and a housing. The transmitter provides a driving force to the sensor, measures the Coriolis effect when the fluid passes through the vibrating pipe, and converts the measured signal into a mass flow signal.

[0034] The inductive element 7 can also be a volumetric flow meter that collects volume signals and a temperature sensor that monitors temperature changes in real time during liquid delivery and transmits data to the control system. The control system calculates real-time mass data through synchronous operation with conversion coefficients based on the received volume and temperature values. This operation method is a mature existing technology and will not be described here.

[0035] In this embodiment, the delivery pump 8 can be a centrifugal pump or a plunger pump, and a check valve is installed at the outlet of each delivery pump 8.

[0036] As a preferred solution of the present embodiment, a heating element 5 for heating the raw materials is also provided on the raw material delivery line. The heating element 5 is arranged after the delivery pump 8 and the inductive element 7, and the heating element 5 uses an electric heater.

[0037] By heating the raw materials through the heating element 5 on the raw material delivery line, first, the kinetic energy of the reactant molecules can be increased, making them more likely to collide and react, thereby increasing the reaction rate. Second, the synthesis reaction of some corrosion inhibitors needs to be carried out under specific temperature conditions, and heating can help maintain these conditions to ensure smooth reaction. Third, heating can reduce the viscosity of the raw materials, making them easier to mix and dissolve, which is very important for ensuring reaction uniformity and product quality consistency. Fourth, by adjusting the temperature and time of heating, the progress of the reaction can be precisely controlled, which is crucial for producing corrosion inhibitors with specific properties.

[0038] An adjusting valve 6 is also provided on the raw material delivery line, and the adjusting valve 6 is arranged after the delivery pump 8 and the inductive element 7. Based on the control of the opening and closing of the delivery pump 8 by the control system, the adjusting valve 6 can further fine-tune the flow and flow rate of the raw materials. For example, if it is necessary to deliver raw materials according to a specific formula ratio during production, when the inductive element 7 finds that the flow deviates, the adjusting valve 6 can adjust the opening degree to make the flow reach the precise value, thereby ensuring the accurate production ratio of the corrosion inhibitor.

[0039] In this embodiment, the production line control system can adopt a mature DCS control system 1 in the industry, and the controller is used to automatically control the production line. The conveying pump 8 and the inductive element 7 are connected with the controller signal. The controller can adopt a PID controller 2.

[0040] The conveying pump 8 on each raw material conveying line has an independent frequency converter and an independent operation control unit at the DCS control end. The DCS control system 1 automatically controls the start of the conveying pump 8. During the conveying and metering process, the computer DCS control system 1 automatically completes the acquisition of mass flow information, or the acquisition of volume flow and temperature information, automatically converts the weight, and automatically adjusts the rotating speed of the frequency conversion pump, so as to realize the addition according to the specified proportion.

[0041] Further, the shear type online mixer is also provided with a frequency converter. According to different product requirements, the rotating speed is determined by the DCS control system 1. While ensuring the mixing intensity, the phenomenon of excessive mixing, emulsification or excessive foaming is avoided.

[0042] The product buffer tank is provided with a glass plate liquid level meter and a high liquid level alarm. The top of the buffer tank is provided with an overflow pipe, and the bottom is connected with an automatic filling system.

[0043] The working process of this embodiment is as follows:

[0044] S1, complete the preparation work before starting, open and close the valve according to the operation procedure, check the device process flow, and make sure that there is no error.

[0045] S2, the control terminal of the DCS control system 1 sets the material flow, and the frequency conversion value of the conveying pump 8 is set to 0.

[0046] S3, slowly start the conveying pump 8, turn on the electric heater, and then increase the rotating speed of the conveying pump 8 after the temperature of each material is normal. The rotating speed of the conveying pump 8 is automatically adjusted, and the flow opening degree is adjusted by a cascade.

[0047] S4, start the shear type mixer, slowly increase the rotating speed of the mixer to the specified value after the inlet temperature rises.

[0048] S5, the product enters the buffer tank, and after reaching the corresponding amount, it is placed and sampled for analysis and detection.

[0049] S6, the product quantity is completed, the power of the conveying pump 8 is quickly cut off by the DCS control system 1, and the material pumping is completed.
