Description

Technical Field

[0001] The invention relates to the technical field of resin production, and in particular to a fully automatic integrated production device and method for suspension polymerization resin. Background Art

[0002] High oil absorption resin has broad application prospects in the fields of environmental protection and oil field exploitation. With the increase of offshore oil spills and oil field produced water, high oil absorption resin has gradually received attention in the treatment and recovery of oily wastewater. This material can effectively adsorb and absorb oil products by virtue of its oleophilic and hydrophobic properties, while maintaining water repellency, thereby achieving rapid separation and recovery of oil products. With the improvement of global awareness of environmental protection and the continuous development of oil field exploitation technology, the market demand for high oil absorption resin continues to grow. Especially in some areas with developed petroleum and chemical industries, the demand for high oil absorption resin is showing a rapid growth trend. At the same time, with the increasingly stringent environmental protection regulations and the continuous improvement of people's awareness of environmental protection, the market demand for high oil absorption resin will continue to grow, providing strong support for the development of related enterprises.

[0003] With the continuous advancement of technology and the continuous expansion of application fields, the prospects for oil-absorbing resins are broad. As an important method for synthesizing highly oil-absorbing resins, suspension polymerization has the advantages of low system viscosity, easy heat transfer control, simple post-processing procedures, and low production costs. However, the current production of oil-absorbing resins is still in the pilot scale, with a low degree of automation. There are usually problems such as complex operating procedures, difficulty in removing monomers and dispersants from the product, and a large amount of contaminated water, which limits the application of resins to a certain extent. Traditional production methods rely on manual operations, which can easily lead to unstable product quality, and a large amount of wastewater is generated during the production process, increasing treatment costs and environmental pollution.

[0042] The present invention will be further described below in conjunction with the accompanying drawings:

[0043] In order to solve the technical defects in the current production process of oil-absorbing resin, such as low degree of automation, large consumption of manpower and time costs, low product purity, and large amount of wastewater generated, the present invention provides a fully automatic integrated production device and method for suspended polymerization resin.

[0044] like Figure 1The fully automatic integrated production device for suspension polymerization oil-absorbing resin shown in the figure includes a raw material tank, a mixing kettle, a reaction and cleaning integrated kettle 15, an ultrasonic vibration cleaning pool 14, a blast drying device 20, a water treatment pool 12 and a pore-forming agent treatment pool 13. The raw material tank includes a liquid raw material tank 2 and a solid raw material tank 1. The mixing kettle includes an oil phase mixing kettle 7 and a water phase mixing kettle 8. The discharge port of the liquid raw material tank 2 is connected to the feed port of the water phase mixing kettle 8; the discharge port of the solid raw material tank 1 is connected to the feed port of the oil phase mixing kettle 7 and the feed port of the water phase mixing kettle 8 respectively. The discharge port of the oil phase mixing kettle 7 is connected to the discharge port of the water phase mixing kettle 8 through a pipeline and then connected to the feed port of the reaction and cleaning integrated kettle 15. The discharge port of the reaction and cleaning integrated kettle 15 is connected to the feed port of the ultrasonic vibration cleaning pool 14, and the blast drying device 20 is arranged at the discharge port of the ultrasonic vibration cleaning pool 14; the water outlet of the reaction and cleaning integrated kettle 15 is connected to the water inlet of the water treatment pool 12, and the water outlet of the water treatment pool 12 is respectively connected to the water inlet of the reaction and cleaning integrated kettle 15 and the water inlet of the water phase mixing kettle 8. The water outlet of the ultrasonic vibration cleaning pool 14 is connected to the water inlet of the pore-forming agent treatment pool 13, and the water outlet of the pore-forming agent treatment pool 13 is connected to the water inlet of the ultrasonic vibration cleaning pool 14 and the liquid raw material tank 2.

[0045] Preferably, the interior of the liquid raw material tank 2 is made of stainless steel to prevent corrosion. A cooling channel is provided on the outer wall of the liquid raw material tank 2, and the cooling channel is filled with circulating water. The circulating water cools the liquid raw material tank 2 and the raw materials in the liquid raw material tank 2 to prevent corrosion and monomer self-polymerization. The liquid raw material tank 2 and the solid raw material tank 1 are both sealed tanks to prevent liquid and solid volatilization and splashing.

[0046] In this embodiment, the liquid raw material tank 2 is used to store liquid raw materials and provide the required liquid raw materials for the subsequent production process of oil-absorbing resin. Through the design of stainless steel material inside and cooling channel on the outer wall, the raw materials are guaranteed to be in a suitable state to participate in the reaction. The liquid raw materials in the production process of suspension polymerization oil-absorbing resin have certain corrosiveness. The use of stainless steel can effectively resist corrosion, extend the service life of the liquid raw material tank 2, and ensure that it can store liquid raw materials stably for a long time. By setting a cooling channel and filling it with circulating water, on the one hand, the liquid raw materials are prevented from being corroded due to excessively high temperature; on the other hand, the monomers in some liquid raw materials will undergo self-polymerization at a specific temperature, affecting the quality of the product, which can be avoided by cooling. The circulating water flows in the cooling channel, continuously taking away the heat of the liquid raw material tank 2 and the raw materials therein. According to the principle of heat conduction, the heat will be transferred from the object with high temperature (liquid raw material tank 2 and raw materials) to the object with low temperature (circulating water), thereby achieving the effect of cooling. By controlling the temperature, the monomers are prevented from self-polymerization at high temperature, ensuring the quality and stability of the raw materials.

[0047] Therefore, the liquid raw material tank 2 used in the present invention not only solves the problems of damage and leakage of the raw material tank caused by corrosion during the storage of liquid raw materials, ensures the safety and continuity of production, but also effectively prevents the self-polymerization of monomers in the liquid raw materials, ensures the quality of the raw materials and the normal progress of subsequent reactions, and helps to improve the purity of the product. Due to the stable raw material storage conditions, the stability of the entire production process is improved, thereby reducing the differences between product batches caused by fluctuations in the state of the raw materials, which is conducive to improving the consistency of product quality.

[0048] In the present embodiment, the solid raw material tank 1 is used to store solid raw materials and provide the solid raw materials required for the mixing process of producing oil-absorbing resin. The solid raw material tank 1 adopts a sealing structure, which can prevent the solid raw materials from volatilizing and splashing during storage and subsequent use, ensuring the cleanliness of the production environment and the effective use of raw materials. Solid raw materials have volatile components, or are prone to flying dust under the disturbance of the production environment. The sealing design can avoid these situations, ensure that the raw materials are not lost and do not pollute the production environment. Through the sealing structure, a relatively closed space is formed, blocking the gas exchange channel between the solid raw materials and the external environment, thereby preventing the gas volatilized by the solid raw materials from escaping and the splashing of raw materials caused by the flow of external air. By adopting a well-sealed solid raw material tank 1, the original state of the raw materials is maintained, so that in the mixing process, the solid raw materials can be more evenly mixed with other raw materials, thereby improving the performance and quality uniformity of the product.

[0049] According to the preferred embodiment of the present invention, a first electric stirring mechanism 6 is respectively provided inside the water phase mixing kettle 8 and the oil phase mixing kettle 7, and the first electric stirring mechanism 6 is used to stir and mix the raw materials in the mixing kettle. A third pneumatic valve 10 is provided at the discharge port of the water phase mixing kettle 8, and a fourth pneumatic valve 11 is provided at the discharge port of the oil phase mixing kettle 7.

[0050] Since the water phase and oil phase raw materials are often composed of multiple components in the process of producing oil-absorbing resin, they need to be fully mixed to ensure the consistency of subsequent reactions and the stability of product quality. Stirring can break the stratification and aggregation state between the raw materials and promote the contact between the components. Therefore, a first electric stirring mechanism 6 is respectively set in the water phase mixing kettle 8 and the oil phase mixing kettle 7, which is used to stir the raw materials in the water phase mixing kettle 8 and the oil phase mixing kettle 7, so that different raw materials are fully mixed in the kettle to achieve a uniform distribution state. The first electric stirring mechanism 6 drives the stirring paddle to rotate through the motor, and the stirring paddle generates shear force and convection on the liquid or mixed material in the kettle during the rotation process. This shear force and convection can make different raw material particles move at different positions in the kettle, thereby achieving uniform mixing. For example, when the stirring paddle rotates, the material close to the stirring paddle is driven to rotate rapidly, and diffuses to the surrounding under the action of centrifugal force. At the same time, the material at the bottom and edge of the kettle will be drawn into the stirring area, forming a circulating flow of the material, and achieving a mixing effect. This design solves the problem of uneven mixing of water-phase and oil-phase raw materials, avoids incomplete reactions or inconsistent product performance due to local concentration differences, ensures that subsequent reactions are carried out under uniform raw material conditions, makes subsequent polymerization reactions more complete and stable, and improves the oil absorption and mechanical properties of the oil-absorbing resin.

[0051] Preferably, according to the present invention, the discharge port of the liquid raw material tank 2 is connected to the feed port of the water phase mixing kettle 8 through a pipeline, and a first pneumatic valve 3 and a first flow meter 4 are provided on the pipeline.

[0052] In this embodiment, the first pneumatic valve 3 is used to control the flow of liquid raw materials from the liquid raw material tank 2 to the water phase mixing kettle 8, and can be opened or closed according to production requirements to achieve precise control of the delivery of liquid raw materials. The first flowmeter 4 is used to measure the flow of liquid raw materials flowing from the liquid raw material tank 2 to the water phase mixing kettle 8, and monitor the delivery amount of raw materials in real time. In the production process, it is necessary to accurately control the timing and amount of adding liquid raw materials. The pneumatic valve has the characteristics of fast response speed and high control accuracy, which can meet the needs of automated production. By receiving the signal of the control system, the pneumatic valve uses compressed air to drive the opening and closing of the valve. When the opening signal is received, the compressed air enters the cylinder to push the piston, so that the valve opens and the liquid raw material begins to flow; when the closing signal is received, the piston drives the valve to close under the force in the opposite direction, and stops the flow of liquid raw materials. Accurately knowing the flow rate of liquid raw materials is crucial to ensuring product quality. Different product formulas require liquid raw materials with a specific flow rate. The flowmeter can provide accurate flow data, which is convenient for accurate batching. The first pneumatic valve 3 solves the problem of precise control of liquid raw material delivery, avoids excessive or insufficient addition of raw materials, and ensures the accuracy of ingredients for each production; the first flow meter 4 accurately measures the flow of liquid raw materials, which helps to achieve precise formula control, improve the stability of product quality, and reduce product quality fluctuations caused by inaccurate raw material dosage; the combination of the two can achieve more sophisticated automated control, and precise control can reduce the generation of waste and reduce production costs.

[0053] Preferably, according to the present invention, the discharge port of the solid raw material tank 1 is connected to a vacuum feeder 5 through a pipeline, the inlet of the vacuum feeder 5 is connected to the discharge port of the solid raw material tank 1, and the outlet of the vacuum feeder 5 is respectively connected to the feed port of the oil phase mixing kettle 7 and the feed port of the water phase mixing kettle 8 through a pipeline. A second pneumatic valve 9 is provided at the outlet of the vacuum feeder 5.

[0054] In this embodiment, the vacuum feeder 5 is used to transport the solid raw materials from the solid raw material tank 1 to the oil phase mixing kettle 7 and the water phase mixing kettle 8 to realize the automatic feeding of the solid raw materials. The second pneumatic valve 9 is used to control the transportation of the solid raw materials from the vacuum feeder 5 to the mixing kettle, and can be opened and closed as needed. In production, the transportation of solid raw materials requires an efficient, clean and automated production method. The vacuum feeder 5 uses vacuum suction to absorb and transport solid raw materials without manual handling, which reduces labor costs and labor intensity, and can avoid pollution and errors in the manual feeding process. The vacuum feeder 5 generates a negative pressure environment inside it through a vacuum pump, and the solid raw materials in the solid raw material tank 1 are sucked into the vacuum feeder 5 under the action of the pressure difference. Then, by switching valves and other operations, the solid raw materials are transported to the mixing kettle under positive pressure or gravity. This transportation method using air pressure difference can adapt to solid raw materials of different properties, and can realize continuous or intermittent feeding. Similar to the first pneumatic valve 3, it is necessary to accurately control the timing and amount of solid raw material delivery to meet the production process requirements. The working principle of the second pneumatic valve 9 is the same as that of the first pneumatic valve 3. The second pneumatic valve 9 realizes precise control of the delivery of solid raw materials, ensuring that the amount of solid raw materials delivered to the mixing kettle each time meets the production formula requirements, thereby improving the accuracy of the ingredients. The cooperation between the vacuum feeder 5 and the second pneumatic valve 9 can make the delivery of solid raw materials more stable and accurate, help improve the uniformity of the mixture, and further improve the quality of the product, such as making the structure of the oil-absorbing resin more uniform, thereby improving its oil absorption performance and physical stability. At the same time, the automated feeding system can better match the automated process of the entire production device, thereby improving the overall automation level and reliability of production.

[0055] According to the preferred embodiment of the present invention, the oil phase mixing kettle 7 uses a DSC remote control pneumatic valve and a flow meter to accurately pump the monomer / crosslinking agent and other oil phase raw materials into the mixing kettle, and uses an electric stirring mechanism to mix the raw materials uniformly. The water phase mixing kettle 8 is remotely controlled by DSC, and solid raw materials such as initiators / dispersants are added to the mixing kettle by a vacuum feeder 5, and water is pumped into the water phase mixing kettle 8, and the electric stirring is turned on to mix the raw materials uniformly until they are completely dissolved.

[0056] In modern industrial production, remote control can improve the automation and convenience of production. By centrally controlling multiple devices, manual on-site operations can be reduced, and production efficiency and safety can be improved. At the same time, it is more convenient to perform precise control according to the preset program to ensure the stability of product quality. DSC (distributed control system) is connected to pneumatic valves, flow meters and other equipment through a communication network. It can receive data feedback from sensors and send control instructions to pneumatic valves and flow meters according to the preset control algorithm to achieve remote monitoring and adjustment of the entire oil phase mixing process. DSC remote control is used to achieve remote control of pneumatic valves and flow meters, coordinate the process of oil phase raw materials entering the mixing kettle, and ensure the automation and precision of the entire process. When the DSC system's opening signal is received, compressed air enters the cylinder, pushing the piston to drive the valve core to move, so that the valve opens and the oil phase raw materials pass through; when the closing signal is received, the compressed air reverses or empties, and the valve core returns to the closed position under the action of the spring or other reset device to cut off the raw material flow. Different oil-absorbing resin products require different proportions of monomers and cross-linking agents and other oil phase raw materials. The combination of DSC remote control system, pneumatic valve and flow meter solves the problem of accurate batching and automatic control of oil phase raw materials, reduces manual operation errors, ensures the accuracy of feed amount and feeding time of oil phase raw materials in each production, and is conducive to improving the stability and repeatability of product quality.

[0057] The DSC remote control system remotely controls the feeding process of the water phase mixing kettle 8, coordinates the addition process of solid raw materials (initiators, dispersants, etc.) and water, and ensures the automation and precision of the operation. Similar to the oil phase mixing kettle 7, remote control improves the automation level of production and the convenience of operation. The water phase mixing process can be uniformly managed according to the preset production process parameters to ensure the stability and accuracy of the production process. The solid raw materials in the solid raw material tank 1 are sucked into the vacuum feeder 5 under the pressure difference between the external atmospheric pressure and the internal negative pressure. Subsequently, the solid raw materials are transported to the water phase mixing kettle 8 by positive pressure or gravity through operations such as valve switching. This conveying principle based on air pressure difference can adapt to solid raw materials of different particle sizes, densities and other properties, and can achieve continuous or intermittent conveying.

[0058] Preferably, according to the present invention, the reaction and cleaning integrated kettle 15 comprises a reaction kettle; a spray mechanism and a second electric stirring mechanism 16 are installed inside the reaction kettle.

[0059] The reaction and cleaning integrated kettle 15 is a core device, which is used to accommodate the raw materials for reaction and clean the products after the reaction, realizing the integration of reaction and cleaning functions and ensuring the continuity of the entire production process. By integrating the reaction kettle and the cleaning kettle, it is not only possible to reduce the equipment footprint and optimize the space utilization of the production site, but also to simplify the production process, reduce the connection between equipment and material transfer links, and improve production efficiency. The functional components such as heating, stirring, and filtering are reasonably arranged inside a kettle body so that they can complete the corresponding functions at different stages to meet the different needs of reaction and cleaning. The reaction and cleaning integrated kettle 15, on the one hand, solves the loss and pollution problems in the raw material transportation process caused by the separation of the reaction kettle and the cleaning kettle, reduces the chance of contact between the materials and the outside world during the transfer process, and improves the product quality; on the other hand, it solves the problem of large equipment footprint, is more adaptable to the production environment with limited space, and reduces the site cost. Due to the close connection between the reaction and cleaning links, the reaction and cleaning integrated kettle 15 reduces some quality changes of the product after the reaction due to waiting for cleaning, avoids the adsorption of impurities or side reactions due to long-term stay, thereby improving the purity and stability of the resin product.

[0060] In the production process of oil-absorbing resin, the reaction and cleaning integrated kettle 15 serves as a place for the reaction to take place, allowing the raw materials to undergo chemical reactions such as polymerization, and can also perform cleaning operations on the products after the reaction is completed, realizing the integration of reaction and cleaning functions, simplifying the production process, and improving production efficiency. The reaction kettle is the core part of the reaction and cleaning integrated kettle 15, which is used to provide a closed and specific environment space, allowing various raw materials to undergo chemical reactions according to predetermined conditions to generate oil-absorbing resin products; at the same time, in the cleaning stage, it serves as a container for the interaction between the cleaning medium and the product.

[0061] The spray mechanism, as an auxiliary mechanism of the reactor, performs the first cleaning of the substances in the reaction process. In the cleaning stage, the spray mechanism sprays the cleaning liquid and other media evenly on the product and the inner wall of the reactor in a spraying manner to achieve comprehensive cleaning of the product, remove impurities, unreacted raw materials, etc. In order to ensure that the cleaning liquid can fully cover various areas in the reactor, especially some places where there are cleaning dead corners, the present invention adopts a spraying method to make the cleaning liquid evenly distributed in the form of dispersed small droplets, thereby improving the cleaning effect. The water inlet of the reactor is connected to the external cleaning liquid supply system through a pipeline, and the cleaning liquid is pushed to the nozzle by pressure. The nozzle disperses the cleaning liquid into many small droplets and sprays them out, similar to the principle of a common shower nozzle, and relies on liquid pressure to achieve uniform spraying. In this embodiment, the cleaning liquid adopts the recycled water obtained after the waste water discharged from the reaction is treated, and a part of deionized water is added, so as to avoid the waste of water resources. The spraying method solves the problems of incomplete cleaning and inadequate local cleaning in the traditional cleaning method, ensures that the product can be cleaned more comprehensively and effectively, and improves the purity of the product. Due to more uniform cleaning, some microstructures on the surface of the product are better protected or modified, thereby showing better performance in subsequent applications. For example, the oil absorption rate of the oil absorbing resin will be improved.

[0062] Since chemical reactions usually require sufficient contact between reactants to proceed more efficiently, the present invention uses an electric stirring mechanism to stir the raw materials, which can break the stratification, aggregation and other phenomena between the raw materials and make the components evenly distributed. During cleaning, stirring can also allow the cleaning liquid to quickly diffuse to all parts of the product. The present invention uses a second electric stirring mechanism 16 to play a stirring role in the reaction stage. In the reaction stage, the second electric stirring mechanism 16 stirs the raw materials in the reactor so that different raw materials are fully mixed and evenly contacted, thereby promoting the progress of the chemical reaction; in the cleaning stage, stirring can also be used to make the cleaning liquid and the product interact better and improve the cleaning efficiency. The stirring paddle is driven by a motor to rotate, and the stirring paddle generates shear force and convection on the materials in the kettle (raw materials in the reaction stage or products and cleaning liquid in the cleaning stage) during the rotation process. The shear force can destroy the agglomeration state between the raw materials or products and the cleaning liquid, and the convection makes the materials circulate at different positions in the kettle to achieve uniform mixing and full contact. For example, a turbine stirring paddle can generate strong axial and radial flows to enhance the stirring effect.

[0063] According to the preferred embodiment of the present invention, a heating jacket 17 is provided on the inner wall of the reactor; a heating cavity is provided in the heating jacket 17, and circulating water is provided in the heating cavity. By providing the heating jacket 17, the reactor is heated to provide suitable temperature conditions for the chemical reaction in the reactor, ensuring that the reaction can proceed smoothly according to the predetermined temperature requirements; in the cleaning stage, the temperature can also be appropriately adjusted as needed to improve the cleaning effect, such as some impurities are more soluble at a specific temperature.

[0064] Many chemical reactions have strict requirements on temperature. The appropriate temperature can accelerate the reaction rate, improve the selectivity of the reaction, etc. The heating sleeve 17 can be used to heat the reactor conveniently and stably to meet the temperature requirements of the reaction. In this embodiment, circulating water is provided in the heating cavity of the heating sleeve 17. By utilizing the principle of heat conduction, the circulating water is heated to transfer heat from the circulating water to the heating sleeve 17, and then from the heating sleeve 17 to the reactor, thereby heating the reactor. The circulating water circulates continuously to ensure a continuous supply of heat and a relatively uniform temperature, similar to the principle of hot water circulation in a radiator to heat the room. Due to more precise temperature control, the microstructure of the product during the reaction process is more regular, thereby improving the physical properties of the oil-absorbing resin (such as strength, toughness, etc.); in the cleaning stage, some stubborn impurities are more easily washed away at a suitable temperature, further improving the purity of the product.

[0065] Preferably, according to the present invention, a retractable filter screen 18 is installed in the reactor. The retractable filter screen 18 is arranged at the bottom of the reactor.

[0066] In order to prevent some impurities or unreacted raw material particles that may appear during the reaction from flowing out of the reactor with the product, causing subsequent equipment to be blocked or affecting product quality, the present invention sets a filter screen for filtering. At the same time, the retractable design of the filter screen is convenient for adjusting its filtering state according to needs at different stages. In the reaction stage, the retractable filter screen 18 performs preliminary filtering on the raw materials in the reactor or some larger particulate matter produced during the reaction process to prevent them from clogging subsequent pipes or equipment. After the reaction is completed, the retractable filter screen 18 can be used to intercept the product, which is convenient for separating the cleaning liquid from the product during the cleaning stage, or for obtaining a relatively pure product sample during sampling. The filter screen has a certain aperture, and only substances smaller than the aperture can pass through, thereby achieving filtering of particles of different sizes. The retractable design can adjust the filter screen area or filtering degree through a mechanical structure (such as a telescopic rod, a foldable structure, etc.). For example, in the early stage of the reaction, the filter screen can be contracted to minimize its hindering effect on the reaction. As the reaction proceeds, the filter screen is gradually expanded for filtering as needed.

[0067] In this embodiment, the retractable filter 18 solves the problem of equipment blockage caused by impurities during the reaction process, as well as the problem of how to effectively separate the product from the cleaning liquid and obtain pure samples during the cleaning and sampling stages, which helps to improve the continuity of production and the accuracy of product quality detection. The retractable filter 18 can effectively filter impurities during the reaction process, making the quality of the product more uniform and showing more stable performance in subsequent applications; when sampling, the purer sample obtained can more accurately reflect the true quality of the product, which is convenient for better quality control.

[0068] Preferably, according to the present invention, a temperature feedback regulation system and a pressure sensing regulation system are arranged in the reactor, and the pressure sensing regulation system is arranged on the top of the reactor.

[0069] Specifically, the temperature feedback regulation system is used to monitor the temperature in the reactor in real time and feed back the temperature information to the control system. The control system adjusts the heating power of the heating sleeve 17 according to the feedback information to ensure that the temperature in the reactor is always kept within a predetermined range and achieve accurate temperature control. Chemical reactions are precise and sensitive to temperature, and even small temperature deviations may lead to unsatisfactory reaction results. The temperature feedback regulation system can detect temperature changes in time and make adjustments to ensure that the reaction is carried out under optimal temperature conditions. It is generally composed of a temperature sensor and a control system connected thereto. The temperature sensor is installed in the reactor and can accurately sense temperature changes and convert them into electrical signals (different types of sensors have different principles, such as thermocouples using thermoelectric effects and thermal resistors using the principle that resistance changes with temperature), and then transmits the electrical signals to the control system. The control system adjusts the heating power of the heating sleeve 17 according to the preset temperature range and the received electrical signals, such as by changing the heating current of the circulating water in the heating sleeve 17 to adjust the heating power. The temperature feedback regulation system solves the problem that it is impossible to monitor and adjust the temperature in real time and accurately by humans, avoids problems such as incomplete reactions and increased side reactions caused by temperature fluctuations, and improves product quality and production efficiency.

[0070] The pressure sensing and regulating system is used to monitor the pressure in the reactor in real time and feed back the pressure information to the control system. The control system adjusts the pressure in the reactor according to the feedback information (such as by exhausting or inletting air) to ensure that the pressure in the reactor is always kept within the predetermined range and achieve precise pressure control. During the chemical reaction, pressure may also have an important impact on the reaction. Different reactions require specific pressure conditions. The pressure sensing and regulating system can detect pressure changes in time and make adjustments to ensure that the reaction is carried out under optimal pressure conditions. The pressure sensing and regulating system consists of a pressure sensor and a control system connected to it. The pressure sensor is installed in the reactor and can accurately sense pressure changes and convert them into electrical signals (different types of pressure sensors have different principles, such as piezoresistive pressure sensors use the piezoresistive effect of semiconductors, and capacitive pressure sensors use the principle that capacitance changes with pressure). The electrical signal is then transmitted to the control system. The control system adjusts the pressure in the reactor according to the preset pressure range and the received electrical signal, such as by opening or closing the exhaust valve or the intake valve to adjust the pressure. The pressure sensing and adjustment system solves the problem that humans cannot monitor and adjust pressure in real time and accurately, avoids problems such as incomplete reaction and increased side reactions caused by pressure fluctuations, and improves product quality and production efficiency.

[0071] In addition, through the accumulation and analysis of temperature and pressure data, the temperature and pressure parameters of the reaction can be further optimized to make the reaction more efficient and stable, thereby improving the quality and performance of the oil absorbing resin.

[0072] Preferably, the reactor is a ceramic reactor. As a container for chemical reaction and cleaning operation, the reactor is made of ceramic material to provide an environment with high chemical stability and strong corrosion resistance, ensuring that during the production of oil-absorbing resin, the reactor itself will not chemically react with raw materials, products or cleaning liquid, thereby ensuring product quality and production continuity.

[0073] In the production process of oil-absorbing resin, raw materials, products and cleaning fluids have certain corrosiveness or chemical activity. Ceramic materials are used to make reactors because ceramics have excellent chemical stability and corrosion resistance and can resist the erosion of these substances. Ceramic reactors solve the problems of equipment damage and product contamination caused by the corrosion resistance of the reactor material, ensure the safety and continuity of production, and improve product quality. Due to the high chemical stability of ceramic reactors, the microstructure of the product in the reaction process is purer, reducing impurities introduced by the reactor material, thereby improving the purity and performance of the oil-absorbing resin.

[0074] Preferably, according to the present invention, a sampling port 19 is provided on the top of the reactor. In order to monitor the quality of the product and the production process in real time, it is necessary to set a portion on the reactor that is convenient for sampling, that is, the sampling port 19 in this embodiment, and take out the sample from the sampling port 19 through a sampling tool (such as a sampling tube, a sampling spoon, etc.). The sampling port 19 is convenient for taking out a certain amount of samples from the reactor during the reaction process or after the reaction is completed, which is used to detect and analyze the quality and composition of the product, so as to timely grasp the situation of the product and adjust the production process parameters. Real-time acquisition of product samples in the reactor for detection and analysis facilitates timely discovery of product quality problems and taking corresponding measures to improve product quality and production efficiency.

[0075] Preferably, according to the present invention, a valve is provided at the bottom of the reactor. In order to achieve accurate control of the flow of materials in the reactor, a valve needs to be provided. According to the requirements of the production process, the product discharge, cleaning liquid injection and other operations are performed step by step by opening and closing the valve. The valve provided at the bottom of the reactor is used to control the outflow of materials such as products and cleaning liquid in the reactor. After the reaction is completed, the product can be released for subsequent treatment by opening the valve. In the cleaning stage, the inlet and outlet of the cleaning liquid can be controlled as needed to achieve an orderly cleaning process.

[0076] Preferably, according to the present invention, the reaction and cleaning integrated kettle 15 is remotely controlled by DSC, and the raw materials that are evenly mixed / completely dissolved in the mixing kettle are pumped into the reaction and cleaning integrated kettle 15, mixed by the second electric stirring mechanism 16 (electric stirrer), heated by the heating jacket 17, and temperature controlled by the temperature feedback regulation system. After the reaction is completed, the retractable filter 18 is opened, the reaction wastewater is discharged into the water treatment tank 12, and the product particles are cleaned with spray water. When the cleaned water is not turbid, the filter is closed and the product is discharged. DSC remote control is used to control the raw material input process of the reaction and cleaning integrated kettle 15, to ensure that the raw materials in the mixing kettle can be accurately and timely pumped into the reaction and cleaning integrated kettle 15, and to realize automated operation.

[0077] Preferably, according to the present invention, the ultrasonic vibration cleaning pool 14 includes a cleaning pool; a plurality of water spraying mechanisms are arranged on the top of the cleaning pool, and an ultrasonic vibration device is installed at the bottom of the cleaning pool. In the production process, if substances such as pore formers and dispersants remain in the product after completing their corresponding functions, it will affect the performance and quality of the product, such as blocking the pore structure of the product and affecting the oil absorption performance, etc., so special cleaning equipment is required for effective removal. The ultrasonic vibration cleaning pool 14 is equipped with a water spraying mechanism, which can effectively remove pore formers and residual dispersants, etc., in combination with ultrasonic vibration cleaning.

[0078] In the production process of oil-absorbing resin, the ultrasonic vibration cleaning tank 14 is a key equipment for deep cleaning of the product, which is used to remove impurities such as pore-forming agents and dispersants remaining on the surface and inside of the product to improve the purity and quality of the product and make it more in line with the use requirements. By installing ultrasonic vibration equipment at the bottom of the cleaning tank to generate high-frequency vibration, the cleaning liquid in the cleaning tank (combined with the spray water provided by the top spray water mechanism) forms tiny cavitation bubbles. These cavitation bubbles will generate strong impact force and microjets during the growth and collapse process, acting on the surface of the product and inside the pores, and peeling impurities off the product. At the same time, the spray water mechanism sprays cleaning water from the top to fully rinse the product, and the combination of the two achieves efficient cleaning. The ultrasonic vibration cleaning tank 14 solves the problem that impurities such as pore-forming agents and dispersants in the product are difficult to completely remove, improves the purity of the product, and avoids the degradation of product performance due to residual impurities, such as the oil absorption performance and mechanical properties of the oil-absorbing resin. Compared with the traditional cleaning method that only relies on immersion or simple rinsing, the ultrasonic vibration cleaning tank 14 can more effectively clean the pore structure inside the product and other difficult-to-clean areas, ensuring the consistency and stability of product quality.

[0079] The spray water mechanism is set at the top of the cleaning pool, and the cleaning water is sprayed evenly on the surface of the product to be cleaned from the top of the cleaning pool to rinse the product comprehensively, which cooperates with the cleaning effect produced by the ultrasonic vibration equipment to enhance the comprehensiveness and effectiveness of cleaning. In order to ensure that the cleaning water can cover all parts of the product, especially the bumps and depressions on the surface of the product that are easy to form cleaning dead corners, the spray method can make the cleaning water evenly distributed in the form of dispersed small droplets to improve the cleaning effect. At the same time, combined with ultrasonic vibration cleaning, a multi-level cleaning method is formed to remove impurities more thoroughly. The spray water mechanism is connected to the external cleaning water supply system through a pipeline, and the cleaning water is pushed to the nozzle by pressure. The nozzle disperses the cleaning water into many small droplets and sprays it out, similar to the principle of common shower nozzles, relying on liquid pressure to achieve uniform spraying. Different types of nozzle designs (such as fan nozzles, cone nozzles, etc.) can produce different spray effects to adapt to different product shapes and cleaning needs. The water spray mechanism solves the problem of incomplete surface cleaning of products when only relying on ultrasonic vibration cleaning. It directly rinses the surface of the product by spraying water to ensure that impurities on the surface of the product can be effectively removed, thereby improving the cleanliness of the product. It cooperates with ultrasonic vibration cleaning to make up for the shortcomings of each cleaning method, forming a more complete cleaning solution and improving cleaning efficiency and product quality.

[0080] The ultrasonic vibration equipment is installed at the bottom of the cleaning pool, generating high-frequency vibration in the cleaning pool, so that the cleaning liquid forms tiny cavitation bubbles. These cavitation bubbles will generate strong impact force and micro jets during the growth and collapse process, acting on the surface of the product and the inside of the pores, stripping impurities from the product, and achieving deep cleaning of the inside and surface of the product. For some products with complex microstructures (such as the pore structure of oil-absorbing resin), traditional cleaning methods are difficult to effectively clean their interiors. The cavitation effect generated by ultrasonic vibration can penetrate into these structures for cleaning and remove impurities. The ultrasonic vibration equipment converts electrical energy into high-frequency mechanical vibration energy through a transducer and transmits it to the cleaning liquid in the cleaning pool. When the cleaning liquid is subjected to high-frequency vibration, the liquid molecules in it will form tiny cavitation bubbles in local areas. These cavitation bubbles continue to grow and expand under the action of the ultrasonic field, and will suddenly collapse when they reach a certain level. At the moment of collapse, extremely high pressure (up to thousands of atmospheres) and high-speed micro jets will be generated. These pressures and micro jets will directly act on the surface of the product and the inside of the pores, forcibly stripping off the impurities attached to them, and achieving deep cleaning.

[0081] Preferably, the blast drying device 20 includes a blower, an anti-static device and an anti-splashing device. The blast drying device 20 can continuously introduce air while heating, so that the particles are suspended in the air, effectively increasing the heating area of ​​the product, improving the drying efficiency and further removing the residue on the surface of the product particles.

[0082] In the production process of oil-absorbing resin, the washed product usually contains a certain amount of water or other volatile substances that need to be removed. If it is not dried, it will affect the quality, storage stability and subsequent processing performance of the product. In order to remove these residual substances efficiently and thoroughly, the present invention adopts a blast drying device 20 to achieve this. The air is continuously introduced into the drying device by the blower. On the one hand, the air is used as a heat transfer medium to transfer heat to the product particles to increase their temperature and evaporate volatile substances such as water; on the other hand, the introduced air makes the product particles suspended in the air, which changes the state of the particles, effectively increases the heating area of ​​the product particles, accelerates the drying speed, and improves the drying efficiency.

[0083] The blast drying equipment 20 solves the problem of untimely and incomplete drying of the product after cleaning, ensures that the product reaches the appropriate degree of drying, and avoids the product from becoming moldy or deteriorating during storage or quality problems in subsequent processing due to residual moisture or impurities. Compared with traditional static drying methods, the blast drying equipment 20 greatly improves the drying efficiency, shortens the production cycle, and is conducive to improving the production efficiency of the entire production process. Since the product particles are dried in a suspended state, the drying process is more uniform, and the degree of drying of the product particles is more consistent, thereby improving the stability of product quality. For example, in the application of oil-absorbing resin, more uniform drying makes its oil absorption performance more consistent in different batches of products. The efficient drying process reduces the performance degradation of the product due to long-term heating or local overheating during the drying process, such as avoiding the influence of certain physical properties of the product (such as toughness) due to excessive drying, thereby maintaining the good performance of the product.

[0084] In the blast drying device 20, the product particles are constantly moving under the drive of the air, and friction occurs between the particles and between the particles and the inner wall of the device, which easily generates static electricity. Static electricity accumulation will threaten product quality and production safety, so it is necessary to set an anti-static device to eliminate static electricity. The present invention uses an existing anti-static device to achieve this function, such as a static eliminator. The strong airflow introduced by the blower will put the product particles in a more violent state of motion, and there is a certain probability that they will splash out from the opening and other parts of the drying device, so it is necessary to set an anti-splash device to limit it. The present invention uses an existing anti-splash device to achieve this function. By setting a physical barrier (such as a filter, a baffle, etc.) to block the splash path of the product particles, or by changing the flow direction and speed of the airflow, the product particles are kept in a relatively stable state of motion in the drying device so as not to splash out. For example, a filter is set at the air outlet and other parts of the drying device, which can allow air to pass through and intercept the product particles to prevent them from splashing. The anti-static device and the anti-splashing device can ensure that the product particles stably complete the drying process in the blast drying device 20, so that the uniformity of drying is further improved, thereby making the product quality more stable.

[0085] Preferably, according to the present invention, the water outlet of the water treatment tank 12 is connected to the water inlet of the reaction and cleaning integrated kettle 15 and the water inlet of the water phase mixing kettle 8 through a recycling water pipeline. A second flow meter is provided on the recycling water pipeline. The water treatment tank 12 is used to perform a series of treatments on the wastewater discharged from the reaction and cleaning integrated kettle 15, including flocculation, precipitation, filtration, acid-base adjustment and neutralization, deionization and other processes, so that the wastewater reaches the reusable standard and realizes the recycling of water resources. By treating the wastewater and making it directly reusable, the dependence on fresh water resources is reduced, the production cost is reduced, and the wastewater discharge is also reduced, which plays a role in protecting the environment.

[0086] In the production process of oil-absorbing resin, the wastewater discharged from the reaction and cleaning integrated kettle 15 contains various impurities, pollutants and substances that affect the subsequent production process (such as inappropriate pH, too many ions, etc.), and needs to be specially treated before it can be reused. Setting up a water treatment pool 12 for multi-process treatment can comprehensively remove these unfavorable factors and ensure the quality of recycled water. Flocculation is to add flocculants to wastewater. The colloidal particles formed after the hydrolysis of the flocculants will adsorb the suspended particles in the wastewater, causing them to aggregate to form larger flocs, which are convenient for precipitation and separation. Sedimentation is to use gravity to make the solid particles with a larger specific gravity in the wastewater naturally sink to the bottom of the pool and separate from the water. Filtration is to set up a filter medium (such as sand filter, activated carbon filter, etc.). When the wastewater flows through the filter medium, the fine particles, impurities, etc. in it are intercepted, and the water quality is further purified. Acid-base adjustment and neutralization is to adjust the wastewater to near neutrality according to the actual pH of the wastewater by adding acidic or alkaline substances to meet the requirements of water quality pH in subsequent production. Deionization uses materials such as ion exchange resins to exchange ions in wastewater with ions on ion exchange resins, thereby removing various ions in wastewater and preventing them from having adverse effects on the production process. The recycled water after multiple processes is of high quality and plays a certain protective role for production equipment during the reuse process, such as reducing scaling and corrosion inside the equipment and extending the service life of the equipment. Stable recycled water quality makes the production process more stable and improves the consistency of product quality, because the reused water will not introduce new unstable factors into the production process.

[0087] In order to smoothly transport the recycled water treated by the water treatment tank 12 to the relevant production equipment, it is necessary to set up a special pipeline to complete this transmission task to ensure that the water flow path is clear and stable. The recycled water pipeline serves as a channel connecting the water outlet of the water treatment tank 12 with the water inlet of the reaction and cleaning integrated kettle 15 and the water inlet of the water phase mixing kettle 8, and transports the treated reusable water to the equipment that needs water, so as to realize the recycling of water resources. By setting a flow meter, the amount of recycled water can be monitored and accurately controlled in real time. The second flow meter can accurately measure the flow rate of recycled water transported to the reaction and cleaning integrated kettle 15 and the water phase mixing kettle 8 through the recycled water pipeline, so as to accurately control the amount of recycled water and ensure that the production process is carried out according to the predetermined water use plan.

[0088] Preferably, according to the present invention, the pore former treatment tank 13 includes a liquid phase separation system and a vacuum distillation system, which are used to separate the backwash liquid from the pore former, and to recover the pore former and the backwash liquid respectively. The pore former treatment tank 13 contains a liquid phase separation system, which can effectively separate the cleaning water from the pore former, and the separated pore former can be reused after detection. By setting up the water treatment tank 12 and the pore former treatment tank 13, the reuse of wastewater and pore former can be effectively improved, the discharge of wastewater and waste liquid can be reduced, the environment can be effectively protected, and the production cost can be reduced.

[0089] In the production process of oil-absorbing resin, washing water containing pore-forming agent will be generated in the washing process. The pore-forming agent is an important auxiliary agent in the production process. If it is directly discharged, it will not only waste resources but also pollute the environment. The pore-forming agent treatment tank 13 is set up for special treatment, which can realize the recycling and reuse of the pore-forming agent and solve the environmental protection problem at the same time. The pore-forming agent treatment tank 13 treats the washing water containing the pore-forming agent, and through its internal liquid phase separation system and vacuum distillation system, the washing water and the pore-forming agent are effectively separated, and the separated pore-forming agent can be reused after detection, which improves the utilization rate of the pore-forming agent and reduces the production cost.

[0090] The liquid phase separation system uses the difference in density and physical and chemical properties between oil and water to separate the oil phase (pore-forming agents are usually oil-soluble and can be regarded as oil phase) and the water phase in the cleaning water through specific devices (such as gravity oil-water separators, centrifugal oil-water separators, etc.). For example, in a gravity oil-water separator, after the cleaning water enters the separator, the oil phase will float on the water phase because the density of oil is lower than that of water. By setting outlets at different heights, the oil phase and the water phase can be collected separately.

[0091] For the separated pore former (oil phase), the vacuum distillation system uses the vacuum distillation principle to perform distillation operation under pressure conditions lower than normal pressure. Because under vacuum conditions, the boiling point of the liquid will decrease, the pore former can evaporate at a lower temperature, and then the evaporated pore former steam is condensed into liquid through a condensation device to achieve further purification and recovery of the pore former. By setting up a vacuum distillation system, the problem of the difficulty in recycling the pore former in the cleaning water is solved, the recovery rate of the pore former is improved, and the production cost is reduced. Because the pore former has an important influence on the pore formation of the product, the pore former is recovered and reused, and the quality of the recovered pore former is relatively stable, which can make the pore structure of the product more uniform and reasonable to a certain extent, thereby improving the oil absorption performance of the oil-absorbing resin.

[0092] From the above, it can be seen that by setting up the water treatment tank 12 and the pore-forming agent treatment tank 13, the wastewater reuse and pore-forming agent reuse can be effectively improved, while reducing production costs, effectively protecting the environment, and playing an important role in optimizing the entire oil-absorbing resin production process.

[0093] The present invention also includes a working method of the above-mentioned fully automatic integrated production device for suspension polymerization oil-absorbing resin, which comprises the following steps:

[0094] S1. Raw material preparation

[0095] Raw material preparation is the starting point of oil-absorbing resin production. It aims to accurately put various raw materials in different states (solid, liquid) into the corresponding mixing kettles (oil phase mixing kettle 7, water phase mixing kettle 8) according to predetermined proportions, and fully dissolve and evenly mix them through stirring, so as to provide a raw material basis with uniform composition and accurate ratio for subsequent reaction links, and ensure the stability and consistency of product quality.

[0096] S11. Through remote DSC control, open the first pneumatic valve 3 and the first flowmeter 4 respectively, put the monomer cross-linking agent and pore-forming agent in the solid raw material tank 1 into the oil phase mixing kettle 7 according to the proportion, and use the vacuum feeder 5 to put the initiator in the solid raw material tank 2 into the oil phase mixing kettle 7. Remote DSC control serves as the control center of the entire raw material preparation process, realizing remote control of various related equipment (such as pneumatic valves, flow meters, vacuum feeders 5, etc.). Through preset programs and instructions, the operation of each device is accurately coordinated to ensure that the operations such as the delivery, transportation and stirring of raw materials are carried out in an orderly manner according to the set processes and parameters, thereby improving the degree of automation and accuracy of production. According to the instructions of the remote DSC, the pneumatic valve is accurately opened or closed to achieve accurate control of the amount and time of solid raw material delivery, ensuring that the amount of solid raw materials delivered to the oil phase mixing kettle 7 each time meets the production formula requirements.

[0097] S12, turning on the first electric stirring mechanism 6 in the oil phase mixing kettle 7 to stir the raw materials in the oil phase mixing kettle 7 at a certain speed, so that various raw materials are dissolved and mixed evenly.

[0098] S13, add a certain proportion of the dispersant and water in the liquid raw material tank 2 to the water phase mixing kettle 8, turn on the first electric stirring mechanism 6 in the water phase mixing kettle 8 to stir the raw materials in the water phase mixing kettle 8, so that various raw materials are dissolved and mixed evenly. In the production process of oil-absorbing resin, the aqueous phase solution is an important component of the reaction system, and the uniformity of its components has an important influence on the reaction result. The dispersant needs to be fully dissolved and evenly distributed in water to play a normal role in subsequent reactions, such as preventing the raw material particles from agglomerating. Add a certain proportion of the dispersant and water in the liquid raw material tank 2 to the water phase mixing kettle 8, and stir through the first electric stirring mechanism 6 in the water phase mixing kettle 8, so that the dispersant is fully dissolved in water and evenly mixed with water to form a uniform aqueous solution, which provides stable and uniform aqueous conditions for subsequent mixing with the oil phase and polymerization reaction.

[0099] Based on step S11 to step S13, it can be known that the present invention realizes precise control of the amount of solid raw materials (monomers, cross-linking agents, pore-forming agents, etc.) and liquid raw materials (initiators, dispersants, etc.) through the synergistic effect of DSC remote control, pneumatic valves, flow meters and other equipment, solves the problems of inaccurate raw material dosage and imbalanced proportions in traditional manual batching, ensures that the raw material ratio produced each time meets the predetermined product formula requirements, and improves the stability and consistency of product quality. The present invention uses DSC, pneumatic valves, flow meters, vacuum feeders 5, etc. to realize automated production, effectively avoiding the damage of dust generated by organic reagents and solid feeding to the environment and operators, reducing the chance of direct manual contact with organic reagents and dust, reducing the risk of pollution to the environment, and ensuring the health and safety of operators.

[0100] S2. Mixing and reaction

[0101] The mixing and reaction refers to mixing the liquids flowing out of the water phase mixing kettle 8 and the oil phase mixing kettle 7 to obtain a mixed solution after the raw materials in the water phase mixing kettle 8 and the oil phase mixing kettle 7 are completely dissolved, and then accurately and stably transporting the mixed solution to the reaction and cleaning integrated kettle 15 by turning on the pump, so as to provide a uniform raw material basis for the subsequent reaction in the reaction and cleaning integrated kettle 15.

[0102] S21, completely dissolving the raw materials in the water phase mixing kettle 8 and the oil phase mixing kettle 7.

[0103] S22, pump the uniformly mixed solutions in the water phase mixing kettle 8 and the oil phase mixing kettle 7 into the reaction and cleaning integrated kettle 15 respectively, and introduce N 2 Shielding gas to slightly positive pressure.

[0104] S23, start the second electric stirring mechanism 16 in the reaction and cleaning integrated kettle 15 to stir the mixed solution in the reaction and cleaning integrated kettle 14, so that the solution is mixed evenly, dispersed from the oil phase to the water phase to form uniform spherical suspension droplets, and the temperature is increased to react, and finally resin particles are formed and hardened. During this period, sampling can be observed through the sampling port 19.

[0105] After the previous raw material preparation stage, the water phase and oil phase raw materials have been dissolved and preliminarily mixed in their respective mixing kettles, but in order to carry out a complete reaction, they need to be further mixed and transferred to a specific reaction container (reaction and cleaning integrated kettle 15). By pumping, the transfer amount and transfer speed of the mixed solution can be automatically and accurately controlled to ensure that the amount of raw materials for each reaction is consistent.

[0106] In order to create an inert reaction environment, N2 protective gas is introduced into the reaction and cleaning integrated kettle 15 to a slightly positive pressure to prevent unnecessary chemical reactions between the raw materials or products in the reaction system and components such as oxygen in the air, thereby protecting the smooth progress of the reaction and the quality of the product. By utilizing the compressibility and fluidity of the gas, N2 gas is transported from a gas source (such as a nitrogen bottle or a nitrogen generator) to the reaction and cleaning integrated kettle 15 through a gas delivery pipeline. When the amount of N2 introduced makes the pressure in the reactor slightly higher than the external atmospheric pressure (i.e., a slightly positive pressure), the infiltration of external air can be effectively prevented, ensuring that the gas environment in the reactor is dominated by N2.

[0107] In the reaction system, if the oil phase and the water phase cannot be fully mixed, it will lead to local concentration differences, making the degree of reaction in different areas inconsistent, affecting the quality and performance of the product. By stirring to disperse the oil phase into uniform suspension droplets, the contact area between the oil phase and the water phase can be greatly increased, and the reaction efficiency and uniformity can be improved. The oil phase and the water phase are mixed more finely and evenly in the reaction and cleaning integrated kettle 15, which will make the subsequent reaction more sufficient and stable at the microscopic level. For example, the cross-linking density of the oil-absorbing resin will be more uniform, thereby improving its oil absorption performance, mechanical properties, etc., and further optimizing product quality.

[0108] During the reaction process, samples are taken regularly or irregularly through the sampling port 19 provided on the reaction-cleaning integrated kettle 15 in order to observe the progress of the reaction and monitor whether the reaction proceeds as expected, including observing the mixing state of the reactants, the formation of the products, etc., so as to promptly discover existing problems and take corresponding measures to ensure product quality.

[0109] S23, heating the circulating water in the heating jacket 17 to a set temperature, and controlling the temperature at the set temperature through a temperature feedback regulation system, while sampling from the sampling port 19 at regular intervals to monitor the reaction conditions, until uniform resin particles are formed and hardened.

[0110] Specifically, the heating jacket 17 heats the circulating water in the heating jacket 17 to provide the required heat for the reaction in the reaction-cleaning integrated kettle 15, so that the reaction is carried out under the set temperature conditions to meet the temperature requirements of the reaction, accelerate the reaction rate, and control the progress of the reaction and the formation of products. The temperature feedback regulation system monitors the temperature in the reaction-cleaning integrated kettle 15 in real time, and feeds back the temperature information to the control system. The control system adjusts the heating power of the heating jacket 17 according to the feedback information to ensure that the temperature in the reaction-cleaning integrated kettle 15 is always controlled at the set temperature, ensure that the reaction is carried out in a stable temperature environment, and improve production efficiency.

[0111] S3, sampling, testing, multiple cleaning and wastewater discharge

[0112] S31. Take solid and liquid water samples from the reaction-cleaning integrated kettle 15 respectively, detect the degree of polymerization of the solid and the viscosity and monomer residue of the liquid. When the requirements are met, open the retractable filter 18 at the bottom of the reaction-cleaning integrated kettle 15, and open the valve at the bottom of the reaction-cleaning integrated valve to discharge the reaction wastewater into the water treatment tank 12 for filtration, precipitation and purification.

[0113] Solid and liquid water samples are taken from the reaction and cleaning integrated kettle 15 for testing, the purpose of which is to understand the degree of polymerization of the solid product (resin particles) after the reaction, as well as the viscosity and monomer residue of the liquid part. These test data are used to determine whether the reaction meets the expected requirements, so as to decide whether to enter the subsequent cleaning process to ensure that the product quality meets the standards. Indicators such as degree of polymerization, viscosity and monomer residue are important parameters for measuring the quality of oil-absorbing resin products. The degree of polymerization affects the physical properties of the resin, the viscosity reflects the flow characteristics of the liquid and is related to the degree of reaction, and the monomer residue affects the purity and subsequent use performance of the product. Therefore, it is necessary to detect these indicators in time after the reaction is completed in order to control the product quality. For different detection indicators, corresponding professional detection instruments and methods are used. For example, gel permeation chromatography is used to detect the degree of polymerization, and the degree of polymerization is determined by analyzing the size distribution of polymer molecules in the sample; a viscometer can be used to detect the viscosity, and the viscosity is measured by using the resistance of the liquid when it flows under specific conditions; chromatographic analysis techniques such as gas chromatography or liquid chromatography are used to detect the monomer residue, and the residual amount is determined by separating and detecting the monomer components in the sample.

[0114] S32, close the valve at the bottom of the reaction and cleaning integrated kettle 15, open the second electric stirring mechanism 16 and the spraying mechanism to spray water into the reactor to clean the resin particles, wash 2-3 times, and discharge the cleaning wastewater into the water treatment tank 12, which treats and recycles the wastewater.

[0115] Sampling and testing are carried out in real time. When the sampling and testing results meet the requirements, the retractable filter screen 18 and the valve at the bottom of the reaction and cleaning integrated kettle 15 are opened to discharge the reaction wastewater into the water treatment tank 12 for filtration, precipitation, and purification. Reaction wastewater usually contains impurities of unreacted raw materials and reaction products. If it is directly discharged, it will pollute the environment and waste water resources. Through the water treatment tank 12, multiple process treatments can be carried out to effectively purify the wastewater so that it meets environmental protection requirements and can be recycled and reused. This step is intended to timely treat the wastewater generated during the reaction process, remove impurities, pollutants, etc., so that it meets the standards for discharge or reuse, reduce pollution to the environment, and realize the rational use of water resources.

[0116] After closing the valve at the bottom of the reaction and cleaning kettle 15, open the spray mechanism to spray water into the reactor to clean the resin particles. This is to remove impurities attached to the surface of the resin particles, unreacted raw materials, etc., to improve the cleanliness of the product and ensure product quality. After the reaction is completed, some impurities will remain on the surface of the resin particles, and natural flushing during the wastewater discharge process cannot be used to clean them thoroughly. Spraying water cleaning can make the cleaning water evenly cover the surface of the resin particles in the form of dispersed small droplets, increase the cleaning contact area, and improve the cleaning effect.

[0117] S33, placing the resin particles into the ultrasonic vibration cleaning tank 14, turning on the ultrasonic vibration for backwashing, passing the backwashing liquid into the spray water mechanism, and the spray water mechanism sprays the backwashing liquid to spray and clean the resin particles. After cleaning for a period of time, taking resin and liquid samples to detect the pore-forming condition of the resin and the residual pore-forming agent, and discharging the backwashing wastewater into the pore-forming agent treatment tank 13.

[0118] S34, after the backwash is completed, turn on the ultrasonic vibration, pass the cleaning water into the spray water mechanism, and the spray water mechanism sprays the cleaning water to clean the resin particles until there is no organic residue. There are some impurities inside the resin particles that are difficult to remove by conventional spray cleaning, especially the residues related to the pore-forming agent and organic residues. Ultrasonic vibration can produce a cavitation effect, so that the cleaning liquid forms tiny cavitation bubbles. These bubbles will produce strong impact force and microjets during the growth and collapse process, acting on the inside and surface of the resin particles to peel off the impurities. At the same time, combined with spray cleaning, the cleaning effect can be further improved to ensure the purity and quality of the product. The present invention uses spray water and backwash liquid for spraying, which effectively increases the contact area between the liquid and the resin particles, improves the cleaning efficiency, and reduces cleaning wastewater and backwash liquid.

[0119] It can be seen from the above technical solutions that the present invention adopts the method of spray cleaning in the reactor, cleaning in the ultrasonic vibration cleaning tank 14, and successively introducing backwashing liquid and cleaning water, which solves the problem that impurities on the surface and inside of the resin particles are difficult to completely remove, improves the cleanliness and purity of the product, ensures that the product quality meets the requirements, and is particularly effective in removing pore-forming agent residues and organic residues. The present invention uses spray water and backwashing liquid for spraying, which effectively increases the contact area between the liquid and the resin particles, improves the cleaning efficiency, and reduces the use of cleaning wastewater and backwashing liquid. This not only shortens the cleaning time and improves production efficiency, but also reduces the cleaning cost, including the procurement cost of cleaning water and backwashing liquid and the cost of wastewater treatment.

[0120] S4. Drying and discharging

[0121] The resin particles are discharged from the discharge port of the ultrasonic vibration cleaning tank 14, and are sent to the air drying device 20 by the conveyor belt 21. The drying temperature and air volume of the air drying device 20 are set, and the resin particles are dried by the air drying device 20 until the resin is free of moisture and discharged.

[0122] The present invention uses air drying to maximize the contact area between air and resin and improve the drying efficiency. The drying temperature and air volume of the air drying device 20 are set, and the water in the resin particles is evaporated and removed by the air drying device 20, so that the resin particles reach a dry state without water, so as to facilitate subsequent unloading and packaging operations. By blowing in air and combining with appropriate temperature control, heat is provided to the resin particles and the evaporation of water is promoted to achieve the purpose of drying. Since the air drying device 20 can maximize the contact area between air and resin, the drying of the resin particles can be made more uniform during the drying process, local overheating or incomplete drying can be avoided at the microscopic level, and the physical properties of the resin particles can be further optimized, such as making their structure more stable, and showing better performance in subsequent applications (such as the oil absorption performance and mechanical properties of the oil-absorbing resin).

[0123] In this embodiment, the resin particles after the previous cleaning process are smoothly and continuously fed into the blast drying device 20 by means of a conveyor belt 21. The conveyor belt plays a bridge role in material transmission, ensuring that the resin particles can enter the drying link in an orderly manner according to the production process, realizing material transfer in the automated production process, reducing manual handling, and improving production efficiency.

[0124] The above-described embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the scope of protection determined by the claims of the present invention.
