Description

Technical Field

[0001] The present invention relates to the technical field of chemical equipment, and particularly to a device for improving the efficiency of chemical reactions. Background Art

[0002] In traditional chemical reactions, gas-liquid, liquid-liquid, solid-liquid and other multiphase reactions are often involved.

[0003] In gas-liquid reactions, the gas-liquid reaction zones generated by traditional gas-liquid reaction equipment are relatively dispersed, and the contact area between gas and liquid is limited. Some gases may aggregate to form larger gas units, while in other areas the gas content is low, resulting in uneven distribution of the gas-liquid mass transfer area in the entire reaction system. In addition, the contact time between the larger gas units and the liquid is limited, and the reactants in the gas do not have enough time to fully dissolve and react before leaving the liquid phase, resulting in insufficient mass transfer. The microphase reactor can generate a multiphase reaction interface, enabling the reactants to perform efficient mass transfer in the reaction interface, which can greatly enhance the reaction efficiency between gas and liquid.

[0004] In liquid-liquid reactions, the two liquids participating in the reaction often have limited mutual solubility and a small phase interface area, resulting in mass transfer only occurring near the phase interface, and it is difficult for the reactants in the large amount of liquid bulk to quickly come into contact and react. In addition, the mixing intensity and micro-mixing effect provided by traditional stirring equipment are limited, and it is difficult to fully disperse the two liquids into tiny droplets and maintain a uniform distribution, resulting in low mass transfer efficiency. Especially for high-viscosity liquids or large-scale reaction systems, stirring is difficult to penetrate deep into the liquid interior, making mass transfer even more difficult. The multiphase reaction interface generated by the microphase reactor can provide a huge phase interface area in the liquid-liquid system, while reducing the interfacial tension and interfacial resistance. This makes it easier for reactant molecules to cross the phase interface for mass transfer, increasing the mass transfer rate, especially for some liquid-liquid reaction systems with difficult mass transfer due to large interfacial resistance, the effect is more significant.

[0005] In solid-liquid reactions, there is a boundary layer between the solid surface and the liquid. Within the boundary layer, the transfer of substances mainly relies on diffusion, and the mass transfer rate is relatively slow. This boundary layer will hinder the transfer of reactants from the liquid bulk to the solid surface and the diffusion of reaction products from the solid surface to the liquid bulk, resulting in low mass transfer efficiency. In addition, the reaction of solid reactants usually occurs at the active sites on their surfaces, and the number of active sites on the solid surface is relatively limited. As the reaction progresses, the active sites may be covered by products or inactivated due to changes in reaction conditions, resulting in a gradual decrease in the reaction rate, limiting the overall reaction conversion and efficiency. The multiphase reaction interface generated by the microphase reaction technology provides more channels and sites for the mass transfer of reactants and products, accelerating the transfer of substances between the solid and liquid phases and accelerating the reaction rate.

[0006] The Chinese patent application with the publication number CN102441359A discloses a chemical reaction tank, which includes a first tank body and a second tank body. A communicating conduit is provided between the first tank body and the second tank body, and a condensing device is arranged on the conduit. An air injection pipe is arranged on the top of the first tank body, and a sewage discharge pipe is arranged on the top of the second tank body, adopting a split design. The structure of this equipment is relatively complex; the installation is complex and the pipelines between the tank bodies are easily damaged; the air injection pipe that generates bubbles is prone to blockage, and the later maintenance cost is high. Summary of the Invention

[0007] In order to solve the above technical problems, the present invention provides a device for improving the efficiency of chemical reactions. The following technical solutions are adopted:

[0008] A device for improving the efficiency of chemical reactions, the device includes a liquid inlet unit, a gas inlet unit, a microphase reactor and a liquid outlet pipe. The outlet of the liquid inlet unit is communicated with the liquid inlet of the microphase reactor, the outlet of the gas inlet unit is communicated with the gas inlet of the microphase reactor. The microphase reactor includes a mixing and heating pipe, a spiral shunt mixer, a high-frequency heater and an outlet part. The liquid entering from the liquid inlet unit and the gas entering from the gas inlet unit are mixed in the mixing and heating pipe. The spiral shunt mixer and the high-frequency heater carry out microphase reactions on the gas-liquid mixture to generate a high-efficiency reaction zone. The liquid outlet pipe is communicated with the outlet part of the microphase reactor.

[0009] By adopting the above technical solutions, the liquid inlet unit is used to introduce the liquid participating in the chemical reaction, and the gas inlet unit is used to introduce the gas or other reaction materials participating in the chemical reaction. The liquid and the gas first form a turbulent flow in the mixing and heating pipe. The high-frequency heater instantaneously raises the temperature of the fluid in the mixing and heating pipe, increasing the molecular motion of the gas-liquid mixture to a greater extent. At the same time, the spiral shunt mixer cuts the gas-liquid mixture, making the liquid turbulent flow more intense, thereby realizing microphase reactions to generate more multiphase reaction interfaces and providing a huge phase interface area in the liquid-liquid system. Moreover, the multiphase reaction interfaces can reduce the interfacial tension and interfacial resistance. This makes it easier for the reactant molecules to cross the phase interface for mass transfer, improving the mass transfer rate, especially for some liquid-liquid reaction systems with difficult mass transfer due to large interfacial resistance, the effect is more significant.

[0010] The multiphase reaction interfaces generated by the microphase reaction technology provide more channels and places for the mass transfer of reactants and products, accelerating the transfer of substances between the solid and liquid phases. The concentration of reactants around the active sites is always maintained at a relatively high level, improving the utilization efficiency of the active sites and accelerating the reaction rate.

[0011] Optionally, the microphase reactor includes an inlet piece, an annular intermediate gas inlet piece, a mixing and heating tube, a spiral shunt mixer, a high-frequency heater, and an outlet piece. The liquid inlet of the inlet piece is communicated with the liquid outlet of the liquid inlet unit. The annular intermediate gas inlet piece includes an intermediate tube assembly and an outer cavity piece. One end of the intermediate tube assembly is communicated with the liquid outlet of the inlet piece. The outer cavity piece is installed around the periphery of the intermediate tube assembly. The outer cavity piece is provided with a feed inlet, and the feed inlet is communicated with the gas outlet of the gas inlet unit. The intermediate tube assembly is provided with gas inlet holes, and the inside of the outer cavity piece is communicated with the inside of the intermediate tube assembly through the gas inlet holes for gas intake. The inlet end of the mixing and heating tube is communicated with the other end of the intermediate tube assembly. The spiral shunt mixer is installed in the mixing and heating tube and is used for cutting the gas-liquid mixture in the intermediate tube assembly. The high-frequency heater is installed around the mixing and heating tube and is used for heating the liquid in the intermediate tube assembly. One end of the outlet piece is communicated with the outlet end of the mixing and heating tube, and the liquid outlet pipe is communicated with the other end of the outlet piece.

[0012] Optionally, the caliber of the inlet piece is smaller than the caliber of the liquid outlet of the liquid inlet unit, and is used for pressurizing the incoming liquid.

[0013] By adopting the above technical solution, the preferred ratio of the caliber reduction is 3:1 - 5:1.

[0014] Optionally, the intermediate tube assembly includes a connecting tube and two inlaid tubes. The two ends of the connecting tube are respectively communicated with the inlet piece and the mixing and heating tube. The two inlaid tubes are respectively inlaid at the disconnected part in the middle of the connecting tube. An adjustable threaded hole is provided on the inlaid tube closer to the inlet piece side, and a threaded plug is arranged in the adjustable threaded hole. By adjusting the position of the threaded plug screwed into the adjustable threaded hole, the flow rate and pressure of the liquid in the connecting tube can be adjusted. An air inlet hole is provided on the other inlaid tube, and is communicated with the outer cavity piece through the air inlet hole.

[0015] Optionally, the outlet piece is in a horn shape, and the caliber at the outlet is larger than the caliber at the inlet.

[0016] By adopting the above technical solution, the preferred ratio of the caliber increase is 1:4 - 1:8; the horn angle is 5° - 15°. The inlet piece can be threaded and can be connected to the pipeline flange and pipeline thread by thread, or can be directly welded to the flange, quick interface and other connection methods. After the high-pressure liquid enters the inlet piece, due to the reduction of the inner hole cross-section, the reduction of the caliber can achieve the purpose of pressurization, and the fluid velocity becomes faster to form a turbulent flow. After the turbulent liquid enters the connecting tube, the insertion depth of the threaded plug can be adjusted to control the cross-sectional area of the channel hole, so as to adjust the flow rate and pressure of the fluid entering the inner hole of the connecting tube. When the high-pressure fluid passes through the adjustable threaded hole, the fluid turbulent flow is more sufficient. The adjustable threaded hole can be designed and processed into a vertical connecting tube and the internal channel of the inlaid tube, or can be processed into a channel with a slope;

[0017] The outer cavity part is provided with an air inlet, and the gas entering from the outside through the air inlet unit enters the interior of the outer cavity part through the air inlet. Since the cross-section of the inner hole of the intermediate pipe assembly becomes smaller when the high-pressure fluid enters, the flow rate becomes faster, and a low-pressure area is formed in the inner hole. Gas is inhaled through the air inlet holes on the inlaid pipe and mixed with the liquid to form a gas-liquid mixture phase.

[0018] The gas-liquid mixture phase enters the mixing heating pipe. The gas-liquid mixture fluid fully contacts the inner wall of the mixing heating pipe. The high-frequency heater instantaneously raises the temperature of the fluid in contact with the inner wall of the mixing heating pipe, increasing the molecular motion of the gas-liquid mixture to a greater extent. At the same time, the spiral shunt mixer cuts the gas-liquid mixture to a greater extent, making the liquid turbulence more intense. The gas-liquid mixture is released at the bell mouth of the outlet part. The interface of the release port becomes larger, the flow rate of the mixed fluid slows down, and the pressure surges.

[0019] Optionally, the liquid inlet unit includes a liquid inlet pipe, a circulation pump, a liquid proportion regulating valve, a pressure transmitter, a liquid flow meter, and a liquid phase pipe. The liquid inlet of the circulation pump is connected to the liquid inlet pipe, and the liquid proportion regulating valve, the pressure transmitter, the liquid flow meter, and the liquid phase pipe are sequentially connected to the liquid outlet of the circulation pump. The liquid outlet of the liquid phase pipe is connected to the inlet part.

[0020] By adopting the above technical solution, the circulation pump provides the kinetic energy of the liquid. The liquid proportion regulating valve, the pressure transmitter, and the liquid flow meter are controlled by a PLC or other programs. According to the set flow meter, the opening degree of the regulating valve is controlled to control the flow rate of the liquid flowing through the pipeline.

[0021] Optionally, the air inlet unit includes a first air inlet pipe, a first gas flow controller, a second air inlet pipe, a second gas flow controller, a mixed air inlet pipe, and a gas proportion regulating valve. The first air inlet pipe and the second air inlet pipe are respectively connected to the air inlet end of the mixed air inlet pipe. The first gas flow controller is used to adjust the flow rate of the first air inlet pipe, the second gas flow controller is used to adjust the flow rate of the second air inlet pipe, the air outlet end of the mixed air inlet pipe is connected to the feed inlet of the outer cavity part, and the gas proportion regulating valve is used to adjust the amount of gas entering the feed inlet from the mixed air inlet pipe.

[0022] By adopting the above technical solution, the first gas flow controller, the second gas flow controller, and the gas proportion regulating valve can be connected to a PLC programmable controller. The set values can be set through the PLC programmable controller to respectively set the flow rates of the gas entering the gas pipeline, and the amounts of the gas entering can be respectively controlled. The air inlet unit can not only introduce gas, but also introduce gas + liquid or gas plus powder. The gas proportion regulating valve plays a role in regulating the proportion and amount of the substances entering the generator.

[0023] Optionally, the device further includes a device box body, an industrial touch screen, and an automatic controller. The industrial touch screen is installed on the device box body. The liquid inlet unit, the gas inlet unit, the micro-phase reactor, and the liquid outlet pipe are installed inside the device box body. The automatic controller controls the execution actions of the liquid inlet unit, the gas inlet unit, and the micro-phase reactor respectively. The industrial touch screen is communicatively connected to the automatic controller.

[0024] Optionally, it further includes a plurality of pressure sensors and a plurality of temperature sensors. The plurality of pressure sensors and the plurality of temperature sensors respectively detect the pressure values and temperature values of each pipeline. The plurality of pressure sensors and the plurality of temperature sensors are respectively communicatively connected to the automatic controller.

[0025] Optionally, the automatic controller is a PLC programmable controller.

[0026] By adopting the above technical solution, the PLC programmable controller can realize the automatic parameter control of the execution actions of the liquid inlet unit, the gas inlet unit, and the micro-phase reactor.

[0027] In summary, the present invention includes at least one of the following beneficial technical effects:

[0028] The present invention can provide a device for improving the chemical reaction efficiency. The liquid inlet unit is used to introduce the liquid participating in the chemical reaction, and the gas inlet unit is used to introduce the gas participating in the chemical reaction. The liquid and the gas first form a turbulent flow in the mixing and heating pipe. The high-frequency heater instantaneously raises the temperature of the fluid in the mixing and heating pipe, increasing the molecular movement of the gas-liquid mixture to a greater extent. At the same time, the spiral shunt mixer cuts the gas-liquid mixture, making the liquid turbulent flow more intense, thereby realizing the micro-phase reaction to generate a multi-phase reaction interface. The multi-phase reaction interface generated by the micro-phase reactor can provide a huge phase interface area in the liquid-liquid system. Moreover, the multi-phase reaction interface can also reduce the interfacial tension and interfacial resistance. This makes it easier for the reactant molecules to cross the phase interface for mass transfer, improving the mass transfer rate, especially for some liquid-liquid reaction systems with difficult mass transfer due to large interfacial resistance, the effect is more significant.

Detailed implementation manners

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] An embodiment of the present invention discloses an equipment for improving the chemical reaction efficiency.

[0036] Refer to Figures 1 - 3 , Embodiment 1, an equipment for improving the chemical reaction efficiency, the equipment includes a liquid inlet unit, a gas inlet unit, a microphase reactor and a liquid outlet pipe 4, the outlet of the liquid inlet unit is communicated with the liquid inlet of the microphase reactor, the outlet of the gas inlet unit is communicated with the gas inlet of the microphase reactor, the microphase reactor includes a mixed heating pipe 33, a spiral shunt mixer 34, a high-frequency heater 35 and an outlet part 36, the liquid entering from the liquid inlet unit and the gas entering from the gas inlet unit are mixed in the mixed heating pipe 33, the spiral shunt mixer 34 and the high-frequency heater 35 carry out a microphase reaction on the mixed gas-liquid to generate a high-efficiency reaction zone, and the liquid outlet pipe 4 is communicated with the outlet part 36 of the microphase reactor.

[0037] The liquid inlet unit is used to introduce the liquid participating in the chemical reaction, and the gas inlet unit is used to introduce the gas or other reaction materials participating in the chemical reaction. The liquid and gas first form a turbulent flow in the mixing and heating tube 33. The high-frequency heater 35 instantaneously raises the temperature of the fluid in the mixing and heating tube 33, increasing the molecular motion of the gas-liquid mixture to a greater extent. At the same time, the spiral shunt mixer 34 cuts the gas-liquid mixture, making the liquid turbulent flow more intense, thereby realizing the micro-phase reaction to generate a multi-phase reaction interface. The multi-phase reaction interface generated by the micro-phase reactor can provide a huge phase interface area in the liquid-liquid system. Moreover, the multi-phase reaction interface can also reduce the interfacial tension and interfacial resistance. This makes it easier for the reactant molecules to cross the phase interface for mass transfer, improving the mass transfer rate, especially for some liquid-liquid reaction systems with difficult mass transfer due to large interfacial resistance, and the effect is more significant.

[0038] The multi-phase reaction interface generated by the micro-phase reaction technology provides more channels and places for the mass transfer of reactants and products, accelerating the transfer of substances between the solid and liquid phases. The micro-flow and stirring effects generated within the multi-phase reaction interface can continuously update the reactant environment on the solid surface, keeping the reactant concentration around the active sites at a relatively high level all the time, improving the utilization efficiency of the active sites, and accelerating the reaction rate.

[0039] Example 2: The micro-phase reactor includes an inlet part 31, an annular intermediate gas inlet part 32, a mixing and heating tube 33, a spiral shunt mixer 34, a high-frequency heater 35, and an outlet part 36. The liquid inlet of the inlet part 31 is communicated with the liquid outlet of the liquid inlet unit. The annular intermediate gas inlet part 32 includes an intermediate tube assembly 321 and an outer cavity part 322. One end of the intermediate tube assembly 321 is communicated with the liquid outlet of the inlet part 31. The outer cavity part 322 is installed around the periphery of the intermediate tube assembly 321. The outer cavity part 322 is provided with a feed inlet 3221, and the feed inlet 3221 is communicated with the gas outlet of the gas inlet unit. The intermediate tube assembly 321 is provided with gas inlet holes, and the inside of the outer cavity part 322 is communicated with the inside of the intermediate tube assembly 321 through the gas inlet holes for gas intake. The inlet end of the mixing and heating tube 33 is communicated with the other end of the intermediate tube assembly 321. The spiral shunt mixer 34 is installed in the mixing and heating tube 33 and is used to cut the gas-liquid mixture in the gas-liquid mixed phase in the intermediate tube assembly 321. The high-frequency heater 35 is installed around the outside of the mixing and heating tube 33 and is used to heat the liquid in the intermediate tube assembly 321. One end of the outlet part 36 is communicated with the outlet end of the mixing and heating tube 33, and the liquid outlet pipe 4 is communicated with the other end of the outlet part 36.

[0040] Example 3: The diameter of the inlet part 31 is smaller than the diameter of the liquid outlet of the liquid inlet unit, which is used to pressurize the incoming liquid.

[0041] Embodiment 4. The intermediate pipe assembly 321 includes a connecting pipe 3222 and two inlaid pipes 3223. The two ends of the connecting pipe 3222 are respectively communicated with the inlet part 31 and the mixing and heating pipe 33. The two inlaid pipes 3223 are respectively inlaid at the disconnection part in the middle of the connecting pipe 3222. An adjustable threaded hole 3211 is provided on the inlaid pipe 3223 closer to the inlet part 31. A threaded plug is arranged in the adjustable threaded hole 3211. By adjusting the position of the threaded plug screwed into the adjustable threaded hole 3211, the flow rate and pressure of the liquid in the connecting pipe 3222 are adjusted. An air inlet hole is provided on the other inlaid pipe 3223, and it is communicated with the outer cavity part 322 through the air inlet hole.

[0042] Embodiment 5. The outlet part 36 is in a horn shape, and the caliber at the outlet is larger than that at the inlet.

[0043] The inlet part 31 can have threads and can be connected to the pipeline flange and pipeline thread by threads, or can be directly welded to the flange, quick interface and other connection methods. After the high-pressure liquid enters the inlet part 31, due to the reduction of the inner hole cross-section and the decrease of the caliber, the purpose of pressurization can be achieved, and the fluid velocity becomes faster to form a turbulent flow. After the turbulent liquid enters the connecting pipe 3222, the insertion depth of the threaded plug can be adjusted to control the cross-sectional size of the channel, so as to adjust the flow rate and pressure of the fluid entering the inner hole of the connecting pipe 3222. When the high-pressure fluid passes through the adjustable threaded hole 3211, the fluid turbulent flow is more sufficient. The adjustable threaded hole 3211 can be designed and processed into a channel perpendicular to the inner channels of the connecting pipe 3222 and the inlaid pipe 3223, or can also be processed into a channel with an inclination;

[0044] The outer cavity part 322 is provided with a feed port 3221. The gas entering from the outside through the air inlet unit enters the inside of the outer cavity part 322 through the feed port 3221. Since the cross-section of the inner hole of the intermediate pipe assembly 321 where the high-pressure fluid enters becomes smaller and the flow velocity becomes faster, a low-pressure area is formed in the inner hole. The gas is sucked in through the air inlet hole on the inlaid pipe 3223 and mixed with the liquid to form a gas-liquid mixture;

[0045] The gas-liquid mixture enters the mixing and heating pipe 33. The gas-liquid mixture fluid fully contacts the inner wall of the mixing and heating pipe 33. The high-frequency heater 35 makes the fluid in contact with the inner wall of the mixing and heating pipe 33 instantly increase the temperature, increasing the molecular movement of the gas-liquid mixture to a greater extent. At the same time, the spiral shunt mixer 34 cuts the gas-liquid mixture to a greater extent, making the liquid turbulent flow more intense and the gas-liquid mixture unit divided into finer particles. The gas-liquid mixture is released at the bell mouth of the outlet part 36. The interface of the release port becomes larger, the flow velocity of the mixed fluid becomes slower, and the pressure surges.

[0047] The circulation pump 12 provides the kinetic energy of the liquid. The liquid proportion regulating valve 13, the pressure transmitter 14, and the liquid flowmeter 15 are controlled by a PLC or other programs. According to the set flowmeter, the opening degree of the regulating valve is controlled, so as to control the flow rate of the liquid flowing through the pipeline.
