Description

Technical Field

[0001] This utility model relates to the field of reactor technology, and in particular to an adjustable vertical continuous liquid-liquid reaction device. Background Technology

[0002] A riser liquid reactor is a vertical tubular reaction device primarily used in liquid-phase or gas-liquid two-phase reaction processes in chemical, petroleum refining, and biochemical industries. The reactor body is a vertically installed pipe, which can be filled with catalysts or packing materials (such as a fixed bed), or it can be designed as an empty tube (such as a plug flow reactor). Liquid or gas-liquid mixtures enter from the bottom or top and flow vertically; the reaction is completed during this flow.

[0003] These types of reactors rely on gravity or static mixers to promote two-phase contact reactions. If the viscosity of the two liquid phases is too high, the density difference is small, or the gas solubility is low, it may lead to insufficient mixing and a decrease in mass transfer efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable vertical continuous liquid-liquid reaction device, which aims to solve the problems of existing reactors relying on gravity or static mixers to promote two-phase contact reaction, resulting in insufficient mixing of reactants, and excessively fast fluid flow rate in the reactor also leading to insufficient reaction.

[0005] To achieve the above objectives, this utility model provides an adjustable vertical continuous liquid-liquid reaction device, including an inner assembly and an outer assembly. The inner assembly consists of a gas delivery pipe, a cover, a liquid delivery pipe, and an inner plate. The cover has a plurality of large circular holes evenly spaced near the outer side of the cover, and a plurality of small circular holes evenly spaced on the inner side. The liquid delivery pipe is glued into the small circular holes. The center of the cover is designed with a raised hollow cylinder with parallel openings for screw fixing to adjust the position of the gas delivery pipe. The inner plate is glued to the lower side of the cover.

[0006] The outer device assembly consists of an outer plate and a liquid outlet hole. The liquid outlet hole is provided on one side of the top of the outer plate, and the outer plate is arranged in a ring outside the inner plate.

[0007] There is a flow gap between the bottom of the inner plate and the bottom of the outer plate.

[0008] The number of large circular holes is 6.

[0009] The number of small round holes is 6.

[0010] The device cover is provided with a sealing assembly, which includes a sealing seat and a retaining ring. The sealing seat is detachably connected to the device cover and is located on the top of the device cover, and is slidably connected to the gas delivery pipe. The retaining ring is detachably connected to the device cover and abuts against the sealing seat.

[0011] The inner wall surface of the outer panel and the outer surface of the inner panel are respectively provided with corrosion-resistant coatings.

[0012] This invention discloses an adjustable vertical continuous liquid-liquid reaction device. A solution is continuously and stably pumped into the device via a delivery pipe, ensuring an uninterrupted supply of reaction materials. Simultaneously, gas is introduced through a gas delivery pipe, generating bubbles that rise within the liquid, promoting mixing and ensuring sufficient contact of reactants, thereby improving reaction efficiency. Furthermore, the reactor design can adapt to different feed flow rates and concentrations, exhibiting high flexibility and adjustability. It can be optimized and adjusted according to actual production needs. This application addresses the problem of insufficient reactant mixing through adjustable gas delivery pipes and by employing an internal and external reactor structure to increase the reaction path and extend the reaction time, thus resolving the issue of incomplete reaction. This overcomes the problems of existing reactors that rely on gravity or static mixers to promote two-phase contact, leading to insufficient reactant mixing, and excessively high fluid flow rates within the reactor also causing incomplete reaction.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] like Figures 1 to 4 As shown, where Figure 1 This is a schematic diagram of the overall structure of an adjustable riser continuous liquid-liquid reaction device. Figure 2 This is a structural diagram showing the location of the liquid outlet 106. Figure 3 This is a schematic diagram showing the placement of the hollow cylinder c. Figure 4 This is a schematic diagram of the installation position of the sealing seat 107. This utility model provides an adjustable vertical continuous liquid-liquid reaction device: including an inner assembly and an outer assembly. The inner assembly consists of a gas supply pipe 101, a cover 102, a liquid supply pipe 103, and an inner plate 104. The outer assembly consists of an outer plate 105 and a liquid outlet 106. This solution solves the problems of existing reactors relying on gravity or static mixers to promote two-phase contact reactions, leading to insufficient mixing of reactants. Furthermore, excessively high fluid flow rates in the reactor also result in insufficient reaction. It is understood that the aforementioned solution facilitates thorough mixing of reactants and enables a complete reaction.

[0021] In this embodiment, the inner component and the outer component form an inner-outer component structure, which directly increases the reaction path, extends the reaction time, and facilitates a complete reaction.

[0022] The device cover 102 has multiple large circular holes a near the outer side of the cover, evenly spaced in a ring, and multiple small circular holes b evenly spaced in a ring on the inner side. The infusion tube 103 is glued into each of the small circular holes b. A hollow cylinder c protrudes from the center of the cover 102, with parallel openings for screw fixing to adjust the position of the gas infusion tube 101. An inner plate 104 is glued to the lower side of the cover 102. During manufacturing, the cover 102 has multiple large circular holes a near the outer side of the cover, evenly spaced in a ring, for adding an internal reaction monitoring device or system. In actual use, the height of the large circular holes a is higher than the liquid outlet 106, preventing liquid overflow. This structure prevents subsequent liquid or gas-liquid mixtures from being discharged from the large circular holes a after adding the internal reaction monitoring device or system. Furthermore, multiple small circular holes b are evenly spaced in a ring on the inner side of the large circular holes a. Multiple small circular holes b are spaced apart, and the infusion tube 103 can be directly glued into the small circular holes b. The infusion tube 103 has a peristaltic pump tube inserted into it, and its height is also higher than the liquid outlet 106. This structure will also prevent the liquid or gas-liquid mixture from being discharged from the infusion tube 103 after mixing. Similarly, a one-way valve will be provided on the top input side of the gas infusion tube 101 to facilitate the one-way delivery of gas from the outside to the inside. The hollow cylinder c has parallel openings with threaded holes for screw installation. The screws can be used to adjust the position of the gas infusion tube 101. When adjusting, the screw is loosened. At this time, the front end of the screw does not abut against the surface of the gas infusion tube 101. Then, the gas infusion tube 101 can be directly slid vertically to adjust its position. After adjustment, the screw is tightened to abut and limit the position. The inner plate 104 and the cover 102 cooperate to form a T-shaped structure.

[0023] The outer device assembly consists of an outer plate 105 and a liquid outlet 106. The liquid outlet 106 is provided on one side of the top of the outer plate 105, and the outer plate 105 is arranged in a ring around the outer side of the inner plate 104.

[0024] There is a flow gap between the bottom of the inner plate 104 and the bottom of the outer plate 105. This structure facilitates the discharge of liquid or gas-liquid mixtures from the outlet hole 106.

[0025] Secondly, the number of large circular holes a is 6.

[0026] Then, the number of small round holes b is 6.

[0027] Furthermore, the sealing seat 107 is detachably connected to the cover 102 and is located on top of the cover 102, and is slidably connected to the gas delivery pipe 101; the retaining ring 108 is detachably connected to the cover 102 and abuts against the sealing seat 107. The cover 102 is provided with a stepped mounting groove, and a hollow cylinder c is provided at the bottom of the mounting groove. The sealing seat 107 is provided with a through hole for sliding engagement with the gas supply pipe 101. The through hole is provided with a mounting groove to facilitate the installation of the O-ring rubber sealing ring. The sealing ring is used to seal the sliding contact between the gas supply pipe 101 and the sealing seat 107. The outer side of the sealing seat 107 is provided with a mounting groove, and the mounting sealing ring is fitted in the mounting groove to seal the mating point between the sealing seat 107 and the cover 102. Thus, the above-mentioned sealing ring structure can prevent subsequent liquid or gas-liquid mixture from leaking out from the gap between the sealing seat 107 and the cover 102 or the gap between the sealing seat 107 and the gas supply pipe 101 after mixing. The cover 102 is provided with a retaining spring hole at the top position of the sealing seat 107 after installation to facilitate the installation of the retaining spring 108. The retaining spring 108 is a hole retaining spring used to limit the sealing seat 107 and prevent the device from moving vertically.

[0028] Finally, the inner wall surface of the outer panel 105 and the outer surface of the inner panel 104 are respectively provided with a corrosion-resistant coating. This structure helps to improve the service life of the outer panel 105 and the inner panel 104.

[0029] When using this invention to address the problems of insufficient mixing of reactants in existing reactors that rely on gravity or static mixers to promote two-phase contact reactions, and the incomplete reaction caused by excessively high fluid flow rates, the present invention firstly continuously and stably pumps the solution into the reactor through the liquid inlet pipe 103 to ensure an uninterrupted supply of reactant material. Simultaneously, gas is introduced through the gas inlet pipe 101, and the resulting bubbles rise in the liquid, promoting mixing within the liquid and ensuring sufficient contact of reactants, thereby improving reaction efficiency. Furthermore, the reactor design can adapt to different feed flow rates and concentrations, exhibiting high flexibility and adjustability. It can be optimized and adjusted according to actual production needs. This application solves the problem of insufficient reactant mixing by using the adjustable gas inlet pipe 101 to agitate the gas flow. By employing an internal and external reactor structure, the reaction path is increased, and the reaction time is extended, thus resolving the problem of insufficient reaction. This addresses the issues of insufficient mixing caused by existing reactors relying on gravity or static mixers to promote two-phase contact reactions, and the incomplete reaction caused by excessively high fluid flow rates.

[0030] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
