Description

Technical Field

[0001] The invention relates to the technical field of chemical production equipment, and in particular to a device and a process for reducing the entrainment of condensed gas phase colloid particles. Background Art

[0002] The filter is one of the most widely used equipment in the pipeline transportation system. It is mainly used to remove solid impurities and particles in the fluid to ensure the cleanliness of the fluid and the normal operation of the equipment. The filter is usually composed of a cylinder, a filter screen, a venting and draining device, a flange, a flange cover, fasteners, and instrumentation and electrical control parts. In the condensation unit, the oil and gas filter usually adopts a basket filter, and the filter screen is in the shape of a filter basket. When the fluid flows through the filter basket, the solid particles and impurities will be blocked by the filter screen to form a filter cake, while the filtered clean fluid flows out through the gap of the filter basket and is finally discharged from the outlet of the filter.

[0003] As impurities continue to accumulate, the filter cake gradually thickens and the fluid resistance gradually increases, which requires regular cleaning of the filter. Although basket filters are relatively easy to maintain and widely used, in actual production, oil and gas filters often need to be manually isolated and switched, and the filters need to be dredged and kept ready after the switch is completed. In this process, operators and maintenance personnel face many safety hazards. At the same time, the rubber particles adhering to the filter are difficult to clean, and the conventional high-pressure cleaning method can easily damage the wire mesh on the filter basket, causing the filter to deform or break, and thus unable to ensure a good filtering effect. If the filter is damaged, the rubber particles may leak and enter the heat exchanger, thereby damaging the equipment and causing economic losses. Therefore, the filter must be replaced in time, which also increases maintenance costs.

[0004] In order to solve the above problems, the present invention starts from the source of the condensed first kettle gas phase and adopts a specific process equipment to reduce the solid colloid particles in the fluid, thereby extending the switching cycle of the oil and gas filter, reducing the frequency of cleaning and replacement of the filter, reducing the equipment damage rate, and ultimately achieving the goal of reducing maintenance costs.

This effect extends the stable operation cycle of the oil-gas filter and oil cooler, and reduces the equipment maintenance cost; (2) Reduce the loss of rubber particles: Since the inner wall of the cylinder and the surface of the tower plate have been polished and the slope of gravity fall is designed, the rubber particles are not easy to adhere to the tower plate and the inner wall of the cylinder, but can automatically fall back into the kettle, thereby reducing the loss of rubber particles and increasing the output of rubber; (3) Cleaning function: For rubber particles with high oil content and high viscosity, they may adhere to the inner cover tower plate, hindering the free fall of the rubber particles.

[0019] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Styrene butadiene rubber is one of the earliest synthetic rubber varieties to achieve industrial production and has the largest production capacity. It is a random copolymer of styrene and butadiene and is widely used in vulcanized rubber products such as tires, plastic modification, and shoe materials. Styrene butadiene rubber has excellent heat resistance, wear resistance, and aging resistance. Its processing performance and product performance are close to those of natural rubber, and its vulcanization performance is better than that of natural rubber. Its main production processes are emulsion polymerization and solution polymerization.

[0021] Emulsion polymerization adopts a free radical polymerization mechanism, but it has disadvantages such as wide molecular weight distribution and uncontrollable structure. In addition, more additives are added during the emulsion polymerization process, and the emulsifier residue in the product is high, resulting in certain quality defects, and the production process produces more sewage, which is easy to pollute the environment. In contrast, solution polymerization uses alkyl lithium to initiate the random copolymerization of butadiene and styrene, which can accurately control the monomer ratio, sequence distribution, microstructure and molecular weight, with a narrow molecular weight distribution, high product purity, excellent performance, and no pollution in the production process, with little impact on the environment. The technical innovation of the present invention is mainly focused on the optimization of the coagulation process of solution-polymerized styrene-butadiene rubber.

[0022] The production equipment of solution-polymerized styrene-butadiene rubber usually consists of a tank area, a raw material refining unit, an additive preparation unit, a polymerization unit, a blending unit, a coagulation unit, a post-processing unit and its public auxiliary facilities. The tank area is responsible for storing the production raw materials. After being processed by the refining unit, the raw materials enter the polymerization unit together with the production additives for solution polymerization reaction. The polymerized rubber liquid enters the blending unit to adjust the Mooney index. The rubber liquid that meets the requirements is mixed with a dispersant and hot water and enters the coagulation unit. In the first coagulation kettle, the solvent in the rubber liquid is removed by steam flash evaporation, and the gas phase produced is rich in water vapor and solvent. These gases are filtered through a basket filter, and the rubber particles are separated and then enter the oil-gas condenser for condensation. The solvent obtained by the final condensation will flow back to the refining unit for recycling. The rubber particles at the bottom of the coagulation kettle enter the post-processing unit for further drying, pressed into blocks, and packaged for storage.

[0023] Since the gas in the first condensation kettle rises a large amount, the mixed gas phase of water vapor and solvent can easily carry out a large amount of solid colloid particles. Therefore, a basket filter is usually set between the gas phase outlet at the top of the first condensation kettle and the oil-gas condenser to separate the colloid particles in the gas phase and prevent the colloid particles from entering the oil-gas condenser to avoid blockage. However, if the oil-gas condenser is blocked, at least the condensation effect will be affected, resulting in solvent loss; at worst, the condenser may be damaged, affecting the normal production. To this end, the present invention aims to design an apparatus and process for reducing the entrainment of colloid particles in the condensation gas phase, thereby extending the operation cycle of the oil-gas filter, thereby reducing maintenance costs, reducing safety operation risks, and maintaining the stability of the device production.

[0024] An embodiment of the present invention provides a device for reducing the entrainment of condensed gas-phase particles, which is a sieve plate tower. The sieve plate tower includes a cylinder 10, a head 20 and a tower internal 30. The head 20 is connected to both ends of the cylinder 10, and the tower internal 30 is arranged inside the cylinder 10. The tower internal 30 includes: an outer ring plate 31, which is arranged around the inner wall of the cylinder 10; an inner cover plate 32, which is arranged between the outer ring plates 31 at intervals and relatively arranged at the center of the cylinder 10; and a rubber baffle plate 33, which is arranged at the bottom of the cylinder 10.

[0025] The present invention provides a sieve plate tower device for reducing the entrainment of condensed gas phase colloid particles. The sieve plate tower is composed of a cylinder 10, a head 20 and a tower internal 30, wherein the head 20 is connected to both ends of the cylinder 10, and the tower internal 30 is located inside the cylinder 10. The tower internal 30 comprises: an outer ring plate 31 arranged in an annular shape on the inner wall of the cylinder 10, which plays a supporting and guiding role; an inner cover plate 32 is distributed between the outer ring plates 31 at intervals and relatively distributed at the center of the cylinder 10, which may play a more refined gas and liquid diversion function; a rubber baffle 33 is arranged at the bottom of the cylinder 10, which is used to block the upward movement of colloid particles or particulate matter to prevent them from being entrained outside the tower.

[0026] Sieve plate towers are widely used in gas-liquid, gas-solid or liquid-solid separation processes. The entrainment of condensed gas-phase colloid particles is usually a problem of gas carrying away liquid or solid particles, which will lead to reduced separation efficiency and even affect product quality. The core of the present invention is to improve the design of the tower internals 30, especially by reasonably configuring the outer ring plate 31, the inner cover plate 32 and the rubber baffle plate 33, so as to effectively reduce the entrainment of condensed gas-phase colloid particles. Specifically, the role of the outer ring plate 31 is to optimize the distribution of the airflow in the tower through contact with the inner wall of the cylinder 10, reduce the movement of the colloid particles in the airflow, and thus reduce the probability of entrainment. The inner cover plate 32 is distributed at intervals to reasonably adjust the gas-liquid or gas-solid contact area, enhance the separation efficiency of the material, and further reduce the entrainment of gas-phase colloid particles. The rubber baffle plate 33 is located at the bottom of the tower to prevent the ascending colloid particles from being carried away by the airflow, especially the gas-phase colloid particles will not be entrained outside the tower, avoiding pollution or efficiency loss.

[0027] By rationally designing the structure of the tower internals 30, the entrainment of condensed gas phase particles can be reduced, thereby improving the separation efficiency and processing capacity of the sieve plate tower. Reducing the entrainment of gas phase particles can effectively prevent material loss, reduce resource waste and environmental pollution, and improve product yield. Effective airflow control and gas-liquid / gas-solid separation reduce dynamic fluctuations in the tower, contribute to the stable operation of the sieve plate tower, and reduce equipment maintenance and operating costs.

[0028] It should be noted that the tower internals 30 are all made of S304 stainless steel. The outer ring plate 31 and the inner cover plate 32 are both sieve-hole tower plates with a pore size of 6 mm and an opening rate of 15%. The sieve holes are arranged in an equilateral triangle. The bottom gas phase baffle plate 33 has a pore size of 3 mm and an opening rate of 15%. The sieve holes are arranged in an equilateral triangle. The bottom surface of the baffle plate 33 is polished, and the polishing accuracy Ra is 0.2μm-0.8μm.

[0029] In some embodiments of the present application, the outer ring plate 31 is inclined toward the bottom of the cylinder 10, and the inclination taper of the outer ring plate 31 is 30 degrees-120 degrees; and / or the hollow diameter of the outer ring plate 31 is 200mm-600mm; and / or the height of the outer ring plate 31 inclined toward the bottom of the cylinder 10 is 5mm-7mm; and / or the tower plate spacing of the outer ring plate 31 is 60mm-240mm.

[0030] The outer ring plate 31 is inclined toward the bottom of the cylinder 10, and the range of the inclination taper is 30 degrees to 120 degrees. This design optimizes the fluid dynamics performance of the equipment or increases the space utilization inside the equipment by adjusting the inclination angle of the outer ring plate 31, thereby improving its working efficiency or enhancing its structural stability. The hollow diameter of the outer ring plate 31 is between 200mm and 600mm. This design may enable the outer ring plate 31 to adapt to equipment of different specifications or different process requirements, and provide sufficient space to accommodate fluid or gas flow. The height of the outer ring plate 31 inclined toward the bottom of the cylinder 10 is 5mm to 7mm. This design can ensure that the contact area between the outer ring plate 31 and the cylinder 10 or the path of fluid flow is optimized, further improving the distribution effect of the fluid, or reducing the resistance of fluid flow. The tower plate spacing of the outer ring plate 31 is set to 60mm to 240mm. This spacing involves the structural design of the tower plate, which in turn affects the distribution effect of the tower plate, the contact area between the liquid and the gas, and optimizes the material exchange process.

[0031] Adjustment of the inclination angle of the outer ring plate 31 can have a positive impact on the overall working efficiency of the device. A reasonable inclination angle helps to evenly distribute the fluid inside the device, avoid dead zones or uneven flow of the fluid inside the device, thereby improving the performance of the device and the material exchange efficiency. At the same time, this design can also reduce energy loss caused by uneven flow and improve overall energy efficiency.

[0032] The design of the hollow diameter of the outer ring plate 31 can be adjusted according to actual needs, providing flexibility and adaptability. A larger hollow diameter helps the fluid flow smoothly, reduces flow resistance, and thus improves the operating efficiency of the system. For devices of different sizes or different flow requirements, the hollow diameter can be adjusted to ensure the best working state of the device.

[0033] The tilt height of the outer ring plate 31 is in the range of 5 mm to 7 mm, which can effectively improve the fluid distribution without adding extra burden. This slight tilt change helps to optimize the flow path of the fluid in the cylinder 10, improve the flow uniformity, avoid fluid retention or insufficient flow state, and ultimately improve the overall performance.

[0034] The appropriate plate spacing has a direct impact on the material transfer efficiency in the tower. Appropriate plate spacing can ensure sufficient contact between gas and liquid, thereby improving the gas-liquid exchange efficiency. Too large a spacing leads to insufficient gas-liquid contact, while too small a spacing leads to blockage or low efficiency of the fluid channel. By adjusting the plate spacing, the plate structure can be optimized and the separation and absorption performance of the equipment can be improved.

[0035] In some embodiments of the present application, the inner cover plate 32 is a conical tower plate with a high middle and a low edge; and / or the diameter of the inner cover plate 32 is 400mm-1200mm; and / or the height of the inner cover plate 32 is 9mm-18mm; and / or the tower plate spacing of the inner cover plate 32 is 60mm-240mm; and / or the inclination taper of the inner cover plate 32 is 30 degrees-120 degrees.

[0036] The inner cover plate 32 is a conical plate with a high middle and low edges. This structure makes the inner cover plate 32 present a cone, thereby forming a flow path in the tower that is more conducive to gas-liquid or gas-solid separation, and improving the material transfer efficiency inside the equipment. The diameter of the inner cover plate 32 is 400mm to 1200mm, and this diameter range can be adjusted according to actual needs to adapt to sieve plate tower equipment of different sizes, ensure the uniformity of fluid flow and optimize the material separation effect in the tower. The height of the inner cover plate 32 is 9mm to 18mm, and the appropriate height can ensure that the inner cover plate 32 has sufficient support and stability in the tower, and at the same time plays a regulating role in the gas-liquid distribution and contact process. The plate spacing of the inner cover plate 32 is set to 60mm to 240mm. The appropriate plate spacing can optimize the area of ​​gas-liquid or gas-solid contact, improve the material exchange efficiency, and thus enhance the separation performance of the equipment. The inner cover plate 32 has an inclination taper of 30 to 120 degrees. The setting of the taper is crucial for the guidance and distribution of the fluid. The flow direction of the fluid can be adjusted through a reasonable inclination angle to further improve the separation efficiency.

[0037] The inner cover plate 32 is a conical plate with a high center and low edges. This conical design can effectively regulate and optimize the flow of fluid in the tower. Since the center of the inner cover plate 32 is higher than the edge, the fluid can be guided to a lower position when passing through the inner cover plate 32, avoiding uneven distribution of the fluid or retention in certain areas of the tower. This helps the gas-liquid or gas-solid separation process and improves the overall processing capacity of the equipment.

[0038] The moderate diameter can provide enough space for the flow of gas-liquid or gas-solid in the tower, avoiding pressure loss or excessive flow rate caused by too narrow fluid flow, thereby improving separation efficiency. This design enables the tower equipment to flexibly adapt to different processing scales and flow requirements, and has strong adaptability.

[0039] The height setting helps to form an appropriate gap or contact area between the inner cover plate 32 and other tower internals 30, thereby improving the contact efficiency between the gas and liquid phases. This height range ensures that the fluid in the tower will not be subject to excessive flow resistance when passing through the inner cover plate 32, and also avoids material accumulation or uneven distribution caused by too low a height.

[0040] Reasonable plate spacing can effectively control the contact degree between gas and liquid or gas and solid, making the separation process more efficient. Too small plate spacing will lead to blockage of fluid channels, while too large plate spacing will cause insufficient gas-liquid contact. Therefore, the appropriate plate spacing design helps to optimize the separation effect and improve the working efficiency of the tower.

[0041] The inclination angle of the conical inner cover plate 32 helps to distribute the fluid in the tower reasonably, reducing uneven flow and stagnation. The inclination angle makes the flow of the fluid more stable and smooth, thereby improving the material exchange efficiency and reducing energy loss.

[0042] In some embodiments of the present application, the rubber baffle plate 33 is a conical tower plate with a high middle and a low edge; and / or the diameter of the rubber baffle plate 33 is 400mm-1200mm; and / or the height of the rubber baffle plate 33 is 9mm-18mm; and / or the tower plate spacing of the rubber baffle plate 33 is 60mm-240mm; and / or the inclination taper of the rubber baffle plate 33 is 30 degrees-120 degrees.

[0043] The rubber baffle 33 adopts a conical tower plate design, in which the middle part is higher and the edge part is lower. This design helps to improve its stability, effectively disperse pressure, and reduce the impact of external forces on it. This structure also helps to improve its fluid dynamic performance or material transmission performance during operation. The diameter of the rubber baffle 33 is 400mm-1200mm. This range of diameter design allows the rubber baffle 33 to be suitable for equipment of different sizes and requirements. The height of the rubber baffle 33 is 9mm-18mm, which can provide different stability and functionality according to different needs. The higher rubber baffle 33 can provide stronger physical support, while the lower rubber baffle 33 can reduce resistance and improve operating efficiency. The spacing between the tower plates is set to 60mm to 240mm, which controls the openness of the grid structure of the rubber baffle 33. The appropriate spacing can optimize the passability of the fluid or material, and can also control the mechanical properties to cope with different workloads. The taper of the rubber baffle plate 33 is designed to be between 30 degrees and 120 degrees, which helps to adjust the pressure resistance and material diversion effect of the rubber baffle plate 33. A larger inclination angle provides a stronger diversion function, while a smaller inclination angle helps to maintain its stability under a large mechanical load.

[0044] Through the rational design of the conical tower plate structure and the appropriate parameters such as diameter, height, and tower plate spacing, the working efficiency of the system can be effectively improved and the resistance in material flow or liquid transportation can be reduced. The conical design helps to improve the overall stability of the rubber baffle 33, and can withstand greater external impact or pressure during operation, thereby extending its service life. By adjusting the inclination angle of the rubber baffle 33 and the tower plate spacing, the material flow path can be better controlled, and the phenomenon of stagnation or accumulation of materials can be reduced, thereby ensuring the stable operation of the system. Through the design of adjustable rubber baffle 33 diameter, tower plate height and spacing, the rubber baffle 33 can be widely used in equipment of different sizes and a variety of working environments, and has strong flexibility and adaptability. Due to the design optimization, the degree of wear of the equipment can be reduced, and the frequency of maintenance and replacement can be reduced, thereby reducing the long-term operation and maintenance costs of the system.

[0045] In some embodiments of the present application, the total height of the sieve plate tower is 1425mm-2850mm; and / or the diameter of the cylinder 10 is 800mm-1600mm; and / or the height of the cylinder 10 is 800mm-1600mm; and / or the tower internals 30 include 3-10 layers of outer ring plates 31, 2-9 layers of inner cover plates 32 and 1 layer of rubber baffle plates 33.

[0046] The total height of the sieve plate tower is set between 1425mm and 2850mm. The height design has a direct impact on the fluid flow, material contact time and separation efficiency in the tower. A taller tower body helps increase the space for material exchange, thereby improving separation efficiency.

[0047] The diameter of the cylinder 10 is set between 800 mm and 1600 mm. The appropriate diameter of the cylinder 10 can provide sufficient flow space for the fluid in the tower, while controlling the flow rate and pressure of the fluid to avoid excessive or insufficient flow rate resulting in low efficiency or unstable operation.

[0048] The height of the cylinder 10 is set between 800 mm and 1600 mm. This height controls the material exchange space at different levels in the tower, affecting the contact and separation effect of gas-liquid or gas-solid. A moderate height of the cylinder 10 helps the fluid to fully react or separate in the tower while avoiding unnecessary waste of space.

[0049] The number of outer ring plates 31 in the tower ranges from 3 to 10 layers. The function of the outer ring plates 31 is usually to support the flow of gas or liquid, distribute fluid or adjust the flow rate. Multiple outer ring plates 31 can increase the contact area of ​​the substances in the tower, thereby improving the separation effect. The number of layers of the inner cover plate 32 is 2 to 9 layers. The inner cover plate 32 is mainly used to further optimize the gas-liquid contact, enhance material distribution, improve the distribution of gas and optimize the separation process. The rubber baffle 33 is usually located at the bottom layer of the tower. Its function is to prevent the leakage of solution or gas, and to play a role of isolation and diversion. The number of layers of the rubber baffle 33 is usually set to 1 layer to avoid excessive structural complexity.

[0050] In some embodiments of the present application, the head 20 includes an upper head 21, which is flange-connected to the top of the cylinder 10; the upper head 21 is an elliptical head 20, the curved surface height of the upper head 21 is 200mm-400mm, and the straight side height of the upper head 21 is 25mm-50mm.

[0051] The upper head 21 is elliptical in shape. Compared with the traditional circular head 20, the elliptical design can optimize the pressure distribution of the head 20 to a certain extent, thereby improving the mechanical properties of the head 20. The curved surface height of the upper head 21 is set in the range of 200mm to 400mm, providing specific strength and pressure bearing capacity. The setting of this height range helps to ensure the reliability and stability of the head 20 under different pressure environments. The straight edge height of the upper head 21 is set to 25mm to 50mm. This height design can ensure that the flange connection between the head 20 and the cylinder 10 has sufficient contact surface and sealing, which helps to improve the sealing effect of the head 20 and prevent leakage.

[0052] In some embodiments of the present application, the head 20 includes a lower head 22, which is connected to the bottom of the cylinder 10; the lower head 22 is a conical head 20, the cone height of the lower head 22 is 200mm-400mm, and the inner wall polishing accuracy Ra of the lower head 22 is 0.2μm-0.8μm.

[0053] The lower head 22 is designed to be connected to the bottom of the cylinder 10 to ensure the sealing and structural stability of the equipment and to prevent material leakage or foreign matter from entering the equipment. The lower head 22 is a conical structure with a gradually narrowing shape design, which helps to improve the fluidity of the fluid in the cylinder 10 and the uniformity of pressure distribution. The setting of the cone height enables the lower head 22 to withstand greater pressure according to actual working conditions while avoiding excessive structure occupying space. The polishing accuracy range of the inner wall is set to 0.2μm to 0.8μm, which aims to improve the fluid dynamics performance of the equipment, reduce fluid resistance, and reduce the deposition and accumulation of materials at the bottom of the cylinder 10. It should be noted that the welding method of the lower head 22 and the straight cylinder section adopts vertical welding.

[0054] In some embodiments of the present application, a cleaning device 40 is provided at a position of the cylinder 10 near the rubber baffle 33. The cleaning device 40 includes a nozzle 41, a pressure pump 42 and a water inlet pipe 43. The nozzle 41 is used to clean the rubber baffle 33, the pressure pump 42 is used to provide pressure to the nozzle 41, and the water inlet pipe 43 is connected to the nozzle 41.

[0055] The technical solution of the present invention relates to a device for cleaning the rubber baffle 33, which includes a cleaning device 40 installed on the cylinder 10 and close to the rubber baffle 33. The cleaning device 40 is composed of a nozzle 41, a pressure pump 42 and a water inlet pipe 43. The nozzle 41 is used to clean the rubber baffle 33, the pressure pump 42 is used to provide sufficient cleaning pressure for the nozzle 41, and the water inlet pipe 43 transports water or cleaning liquid to the nozzle 41, thereby completing the cleaning process of the rubber baffle 33. It should be noted that the nozzle 41, the pressure pump 42 and the water inlet pipe 43 are not shown in the drawings.

[0056] The nozzle 41 is the core component of the cleaning device 40, and is used to spray water or cleaning liquid onto the surface of the rubber baffle 33 to achieve decontamination and cleaning. The function of the pressure pump 42 is to pressurize the water source or cleaning liquid so that it flows to the nozzle 41 through the water inlet pipe 43, ensuring that the cleaning liquid can form sufficient injection pressure at the nozzle 41 to effectively clean the surface of the rubber baffle 33. The water inlet pipe 43 is a water source transmission pipe, which is responsible for transporting the cleaning liquid or water from the water tank to the nozzle 41, and is connected to the pressure pump 42 to ensure that the liquid can provide sufficient flow and pressure during the cleaning process.

[0057] In some embodiments of the present application, the distance between the nozzle 41 and the bottom of the barrel 10 is 45mm-55mm; and / or the aperture of the nozzle 41 is 1mm-5mm; and / or the water jet pressure of the nozzle 41 is 50Mpa-140Mpa.

[0058] The distance between the nozzle 41 and the bottom of the cylinder 10 is set to 45mm to 55mm, that is, a DN50 connection port is reserved at 50mm from the bottom of the cylinder 10 for installing the high-pressure water gun nozzle, the purpose of which is to optimize the coverage of the spray fluid, the spray effect and the fluid flow path, and ensure that the relative position of the nozzle 41 and the bottom of the cylinder 10 is optimal, thereby improving the working efficiency of the entire system. The aperture range of the nozzle 41 is 1mm to 5mm. The size of the aperture directly affects the spray mode, flow rate and pressure of the spray fluid. The appropriate aperture helps the fluid to spray at a specific spray angle and flow rate, thereby achieving precise spray effect and better cleaning performance. The water jet pressure range of the nozzle 41 is 50MPa to 140MPa. The higher pressure can enable the water flow to generate stronger power during the spraying process, thereby improving the spraying effect.

[0059] For example, the cleaning device 40 is composed of a telescopic nozzle 41, a booster pump 42 and a water inlet pipe 43. The system adopts a single flat cleaning nozzle 41 with a nozzle aperture of 1mm-5mm. The cleaning water comes from the hot water of the post-processing unit, and the water flow rate is 50L / min-140L / min. The working pressure of the booster pump 42 must meet the water jet pressure required by the nozzle, which ranges from 50Mpa to 140Mpa. The nozzle 41 is installed in the DN50 reserved hole 50mm from the bottom of the sieve plate tower barrel 10, and is used to regularly spray and clean the gas phase baffle plate 33, dredge the sieve plate tower, and prevent blockage, thereby ensuring the continuous and stable operation of the sieve plate tower device.

[0060] An embodiment of the present invention also provides a process for reducing the entrainment of condensed gas-phase colloid particles, using the equipment as described above, the equipment is connected to the top of the condensation first kettle, and the process includes the following steps: high-temperature and high-pressure steam is introduced into the interior of the condensation first kettle, the solvent containing the colloid particle mixture is vaporized, and then discharged from the gas phase pipeline on the top of the condensation first kettle and sent to the equipment.

[0061] High-temperature and high-pressure steam is introduced into the first condensation kettle. The purpose of this step is to gasify the mixture of rubber particles in the solvent through high-temperature and high-pressure steam. The vaporized solvent is discharged through the gas phase pipeline at the top of the first condensation kettle and sent to the equipment, namely the special sieve plate tower, for subsequent treatment. By adopting the special sieve plate tower, the phenomenon of rubber hanging in the oil and gas filter, oil cooler and gas phase pipeline has been significantly improved, and the continuous and stable operation cycle of the system has been extended to more than three times the original. This not only reduces the operation and maintenance cost of the equipment, but also increases the output of finished rubber.

[0062] like Figure 1As shown, the N1 port of the special sieve plate tower is the gas phase inlet, the N2 port is the gas phase outlet, and the N3 port is the high-pressure nozzle installation port. Specifically, in the process of the present invention, the special sieve plate tower is arranged at the outlet of the gas phase pipeline on the top of the first kettle of styrene-butadiene rubber condensation. When the device is operating normally, the first kettle of condensation continuously sprays high-temperature and high-pressure steam into the first kettle of condensation through a steam jet pump, causing the solvent in the water / rubber mixture to be instantly vaporized. The vaporized mixture is discharged through the gas phase pipeline on the top of the first kettle of condensation, passes through the special sieve plate tower, the oil-gas filter and the oil cooler in turn, and finally enters the oil-water stratification tank to recover the solvent. It should be noted that the connection method between the special sieve plate tower and the first kettle of condensation and the gas phase pipeline adopts a flange connection.

[0063] The condensation reactor is usually used in processes such as chemical reactions or solvent evaporation. Its main function is to promote the gasification of liquid mixtures through steam or heat. In this process, the condensation reactor acts as a reactor, providing a high temperature and high pressure environment to promote the gasification of solvents with colloid particles. The introduction of high temperature and high pressure steam can accelerate the evaporation process of the solvent, making the colloid particle mixture easier to gasify. Under high temperature and high pressure environment, the solvent can quickly turn into gas phase, and the risk of colloid particle entrainment is reduced. The gasified colloid particle mixture is discharged from the condensation reactor through the gas phase pipeline and sent to the equipment for subsequent treatment, which helps to remove the solvent or colloid particles that are not completely evaporated during the gasification process, ensuring that the entrainment of gas phase colloid particles is minimized.
