Description

Technical Field

[0001] This application relates to the field of clean energy equipment technology, and in particular to a hydraulic internal circulation reactor. Background Technology

[0002] An anaerobic reactor is a treatment device that utilizes anaerobic microorganisms to biodegrade organic matter. Because it can produce biogas, a usable clean energy source, it is now widely used in the resource recovery of organic waste and biological waste. To enhance the mixing and mass transfer effect of the anaerobic reactor and improve reaction efficiency, the materials inside the reactor are usually stirred. External power is used to maintain a fully mixed flow state inside the reactor to ensure the continuous progress of the biological reaction. This type of reactor used for treating mixed liquids and equipped with stirring is usually called a total mixed anaerobic reactor (CSTR). Currently used stirring and mixing methods mainly include mechanical stirring, hydraulic stirring, and gas stirring. These technologies have the following problems:

[0003] Mechanical agitation involves fixing the agitator inside the reactor. If the agitator malfunctions, the reactor must be shut down for repairs, which is time-consuming and poses significant safety risks. Furthermore, mechanical agitation results in poor mixing, high energy consumption, and problems such as surface crusting and bottom sludge accumulation.

[0004] Existing hydraulic stirring circulation pumps are located outside the reactor, resulting in small circulation flow, high energy consumption, and the formation of density flow and channel flow inside the tank, with a large range of stagnation and sub-stagnation zones.

[0005] Gas agitation uses the pressure difference generated in a liquid through the circulation of biogas produced in the reactor via a compressor as the driving force for agitation. However, it suffers from problems such as complex system construction, high power consumption, and poor safety. Summary of the Invention

[0006] This application aims to address at least one of the technical problems existing in the related art. To this end, this application proposes a hydraulic internal circulation reactor, which realizes the formation of a top-down vortex flow inside the reactor, with a large circulation flow rate, which can fully mix and stir the solution in the reactor, and can effectively reduce energy consumption.

[0007] The hydraulic internal circulation reactor according to an embodiment of this application includes:

[0008] A reactor, wherein a reaction chamber is provided inside the reactor;

[0009] The inner ring flow component is arranged in the reaction cavity, and is used to drive the liquid in the reaction cavity to form a circulating vortex flow, wherein the inner ring flow component comprises a vortex water inlet part, a vortex water outlet part, a lift channel and a lift pump; the vortex water inlet part is arranged at the bottom of the reaction cavity and has a plurality of vortex water inlet flow channels; a vortex water inlet cavity is arranged at the center of the vortex water inlet part; the vortex water inlet flow channels are connected with the vortex water inlet cavity and the reaction cavity; the vortex water outlet part is arranged at the upper part of the reaction cavity and is located above the vortex water inlet part; the vortex water outlet part has a plurality of vortex water outlet flow channels; a vortex water outlet cavity is arranged at the center of the vortex water outlet part; the vortex water outlet flow channels are connected with the vortex water inlet cavity and the reaction cavity; the lift channel is arranged between the vortex water inlet part and the vortex water outlet part; the lift channel is connected with the vortex water inlet cavity and the vortex water outlet cavity; and the lift pump is arranged in the lift channel and is adapted to drive the liquid in the reaction cavity to flow along the vortex water inlet flow channels, the vortex water inlet cavity, the lift channel, the vortex water inlet cavity and the vortex water outlet flow channels.

[0010] According to the hydraulic inner ring flow reactor, the corresponding liquid is injected into the reaction cavity of the reactor, so that the liquid level is at the normal liquid level, that is, the vortex water outlet part is located below the liquid level.

Specifically, the liquid at the bottom of the reactor is driven by the lift pump to enter the vortex water inlet cavity along the vortex water inlet flow channels, and then enters the lift channel through the vortex water inlet cavity. When the liquid reaches the vortex water inlet cavity through the vortex water inlet flow channels, it enters the vortex water inlet flow channels at a certain angle. Then under the action of the lift pump, the liquid is transported to the vortex water outlet cavity through the lift channel. The vortex water outlet cavity is connected with the vortex water outlet flow channels, and the liquid flows out of the vortex water outlet flow channels into the reaction cavity. The vortex water outlet flow channels also accelerate the liquid to flow out of the vortex water outlet flow channels at a certain angle through the form of a reduced cross section, so that the liquid flows out of the reaction cavity in the form of a vortex flow. Furthermore, the solution at the bottom of the reaction cavity enters the vortex water inlet part in the form of a vortex flow, and then flows out of the vortex water outlet part into the upper part of the reaction cavity in the form of a vortex flow, thereby forming a vortex flow from top to bottom in the reaction cavity, thereby driving the solution in the entire reaction cavity to flow, which can effectively avoid the formation of a stagnant zone in the reaction cavity, reduce energy consumption, and realize hydraulic inner ring flow in the reaction cavity. That is, the present application realizes the formation of a vortex flow from top to bottom in the reactor, has a large circulation flow rate, can sufficiently mix and stir the solution in the reactor, and can effectively reduce energy consumption.

[0038] The application will be described below in conjunction with Figures 1 to 5 The hydraulic internal loop reactor of the present application is described.

[0039] According to the embodiments of the present application, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the hydraulic internal loop reactor comprises:

[0040] a reactor 1, wherein a reaction cavity 11 is arranged inside the reactor 1;

[0041] an internal loop component arranged in the reaction cavity, the internal loop component being used to drive the liquid in the reaction cavity to form a circulating vortex flow, wherein the internal loop component comprises a cyclone water inlet part, a cyclone water outlet part, a lift channel and a lift pump, the cyclone water inlet part 2 is arranged at the bottom of the reaction cavity 11, the cyclone water inlet part 2 has a plurality of cyclone water inlet flow channels 21, a cyclone water inlet cavity 22 is arranged at the center of the cyclone water inlet part 2, the cyclone water inlet flow channels 21 are communicated with the cyclone water inlet cavity 22 and the reaction cavity 11, the cyclone water outlet part 3 is arranged at the upper part of the reaction cavity 11, the cyclone water outlet part 3 is located above the cyclone water inlet part 2, the cyclone water outlet part 3 has a plurality of cyclone water outlet flow channels 31, a cyclone water outlet cavity 32 is arranged at the center of the cyclone water outlet part 3, the cyclone water outlet flow channels 31 are communicated with the cyclone water inlet cavity 22 and the reaction cavity 11, the lift channel 4 is installed between the cyclone water inlet part 2 and the cyclone water outlet part 3, the lift channel 4 is communicated with the cyclone water inlet cavity 22 and the cyclone water outlet cavity 32, the lift pump 5 is arranged in the lift channel 4, and the lift pump 5 is adapted to drive the liquid in the reaction cavity 11 to flow along the direction of the cyclone water inlet flow channels 21, the cyclone water inlet cavity 22, the lift channel 4, the cyclone water inlet cavity 22 and the cyclone water outlet flow channels 31.

[0042] According to the hydraulic internal circulation reactor of the embodiment of the present application, the corresponding liquid is injected into the reaction cavity 11 of the reactor 1, so that the liquid level is at the normal liquid level, i.e. the cyclone water outlet 3 is partially below the liquid level. Then the internal circulation component drives the liquid at the bottom of the reaction cavity 11 to move upwards in the upflow channel 4, so that the liquid at the bottom of the reaction cavity 11 moves to the upper part of the reaction cavity 11, and the liquid at the upper part of the reaction cavity 11 moves downwards in the form of vortex flow. Specifically, the liquid at the bottom of the reaction cavity 11 is driven by the upflow pump 5 to enter the cyclone water inlet cavity 22 along the cyclone water inlet flow channel 21, and then enters the upflow channel 4 through the cyclone water inlet cavity 22. When the liquid reaches the cyclone water inlet cavity 22 through the cyclone water inlet flow channel 21, it enters the cyclone water inlet flow channel 21 at a certain angle, and vortex flow liquid is formed at the bottom of the reactor 1. Then under the action of the upflow pump 5, the liquid is transported to the cyclone water outlet cavity 32 through the upflow channel 4, and the cyclone water outlet cavity 32 is communicated with the cyclone water outlet flow channel 31. The liquid flows out to the reaction cavity 11 through the cyclone water outlet flow channel 31, and the cyclone water outlet flow channel 31 also accelerates the liquid to flow out through the cyclone water outlet flow channel 31 at a certain angle by reducing the cross section, so that the liquid flows out to the reaction cavity 11 in the form of vortex flow. Further, the solution at the bottom of the reaction cavity 11 enters the cyclone water inlet 2 in the form of vortex flow, and then flows out to the upper part of the reaction cavity 11 in the form of vortex flow from the cyclone water outlet 3. Further, the vortex flow is formed between the inner wall of the reaction cavity 11 and the upflow channel 4 from top to bottom, thereby driving the solution in the whole reaction cavity 11 to flow, which can effectively avoid the formation of stagnant zones in the reaction cavity 11, reduce energy consumption, and realize hydraulic internal circulation in the reaction cavity 11. That is, the present application realizes the formation of vortex flow from top to bottom in the reactor 1, has large circulation flow, can fully mix and stir the solution in the reactor 1, and can effectively reduce energy consumption.

[0043] It can be understood that the hydraulic internal circulation reactor is also provided with a feed pipe which is communicated with the reaction cavity 11, so as to inject the mixed liquid and other raw materials into the reaction cavity 11 through the feed pipe.

[0044] It can be understood that the direction of the cyclone at the bottom of the reaction cavity 11 is the same as the direction of the cyclone at the upper part of the reaction cavity 11.

[0045] For example, the tangential angle of the cyclone water inlet flow channel 21 and the cyclone water outlet flow channel 31 is, for example, 15 to 30 degrees.

[0046] In one embodiment of the present application, as shown in Figure 2 and Figure 4 the cyclone water inlet flow channel 21 is communicated with the reaction cavity 11 and the cyclone water inlet cavity 22, respectively. Along the direction of liquid flow of the cyclone water inlet cavity 22, the cross-sectional area of the cyclone water inlet flow channel 21 gradually decreases.

[0047] It can be understood that the liquid at the bottom of the reaction cavity 11 flows along the water inlet end of the cyclone water inlet channel 21 to the water outlet end of the cyclone water inlet channel 21, and then flows from the water outlet end of the cyclone water inlet channel 21 into the cyclone water inlet cavity 22. Since the cross-sectional area of the cyclone water inlet channel 21 gradually decreases along the flow direction of the liquid, the cyclone water inlet channel 21 not only enables the liquid to enter the cyclone water inlet cavity 22 in a vortex flow state, but also increases the speed of the liquid entering the cyclone water inlet cavity 22, thereby forming a vortex flow with a faster speed in the reaction cavity 11, and ensuring the stirring and mixing effect on the material.

[0048] It can be understood that the cross-sectional area of the cyclone water inlet channel 21 gradually decreases along the direction from the water inlet end of the cyclone water inlet channel 21 to the water outlet end of the cyclone water inlet channel 21.

[0049] It can be understood that the cross-sectional area of the cyclone water inlet channel 21 refers to the area of the cross section obtained by cutting the cyclone water inlet channel 21 along the vertical direction.

[0050] In an embodiment of the present application, as shown in Figure 3 and Figure 5 the cyclone water outlet channel 31 communicates with the cyclone water outlet cavity 32 and the reaction cavity 11, respectively. Along the flow direction of the liquid in the cyclone water outlet cavity 32, the cross-sectional area of the cyclone water outlet channel 31 gradually decreases.

[0051] It can be understood that the liquid is transported from the upflow passage 4 to the cyclone water outlet cavity 32, and then flows along the water inlet end of the cyclone water outlet channel 31 and the water outlet end of the cyclone water outlet channel 31 to the upper part of the reaction cavity 11. Since the cross-sectional area of the cyclone water outlet channel 31 gradually decreases along the flow direction of the liquid, the cyclone water outlet channel 31 not only enables the liquid to form a vortex flow, but also accelerates the liquid, so that the liquid flows to the upper part of the reaction cavity 11 in a horizontal, inward and outward vortex flow state and at a faster speed, thereby forming a more stable and effective internal circulation in the reaction cavity 11, and ensuring the stirring and mixing effect on the liquid in the reaction cavity 11.

[0052] It can be understood that the cross-sectional area of the cyclone water outlet channel 31 gradually decreases along the direction from the water inlet end of the cyclone water outlet channel 31 to the water outlet end of the cyclone water outlet channel 31.

[0053] It can be understood that the cross-sectional area of the cyclone water outlet channel 31 refers to the area of the cross section obtained by cutting the cyclone water outlet channel 31 along the vertical direction.

[0054] In an embodiment of the present application, as shown in Figure 1 , Figure 2 and Figure 3As shown, the cyclone water outlet 3 is formed with a water outlet 33 communicating with the cyclone water outlet channel 31, and the liquid in the cyclone water outlet channel 31 is adapted to flow into the reaction chamber 11 through the water outlet 33 at a certain angle, and the water outlet 33 is at least partially below the liquid level in the reaction chamber 11.

[0055] It can be understood that when the liquid is injected into the reaction chamber 11, at least part of the water outlet 33 is below the liquid level in the reaction chamber 11, and when the liquid flows out of the water outlet 33 after passing through the cyclone water outlet channel 31, at least part of the liquid will flow directly below the liquid level in the reaction chamber 11, thereby directly driving the liquid in the reaction chamber 11 to perform cyclone movement. And the height difference between the water outlet 33 and the liquid level above the reaction chamber 11 is not too large, so that when flowing from the water outlet 33 to the liquid level, it can effectively drive the liquid at the liquid level to perform cyclone movement without disturbing the liquid flow in the reaction chamber 11.

[0056] It can be understood that the water outlet 33 of the cyclone water outlet 3 can be below the liquid level in the reaction chamber 11 by adjustment to form a water seal state to prevent gas in the reaction chamber 11 from entering the upflow channel 4. Specifically, the liquid level in the reaction chamber 11 can be adjusted so that the water outlet 33 is below the liquid level in the reaction chamber 11; or the installation height of the cyclone water outlet 3 can be adjusted so that the water outlet 33 is below the liquid level in the reaction chamber 11.

[0057] In an embodiment of the present application, as shown in Figure 1 , Figure 2 and Figure 3 , the hydraulic internal loop reactor comprises a sludge discharge assembly 6, one end of the sludge discharge assembly 6 communicates with the cyclone water inlet chamber 22, and the sludge discharge assembly 6 is adapted to discharge the sludge at the cyclone water inlet chamber 22 to a space outside the reaction chamber 11.

[0058] It can be understood that the bottom of the reactor 1 will deposit sludge, and when the liquid at the bottom of the reactor 1 enters the cyclone water inlet chamber 22 in a cyclone state, the sludge will also enter the cyclone water inlet chamber 22, and part of the sludge will flow to the cyclone water outlet 3 with the liquid, and another part will remain in the cyclone water inlet chamber 22. That is, the cyclone water inlet 2 can not only form a vortex flow at the bottom of the reactor 1, but also concentrate the sludge at the bottom of the reactor 1 in the cyclone water inlet chamber 22, so that when excess sludge needs to be discharged, the sludge in the cyclone water inlet chamber 22 can be directly discharged to the outside of the reaction chamber 11 through the sludge discharge assembly 6, improving the efficiency and effect of sludge discharge, and the present application does not need to additionally provide a special sludge discharge device, but only needs to use the simple structure of the sludge discharge assembly 6 to discharge the sludge in the reaction chamber 11, simplifying the structure of the reactor 1 and reducing the manufacturing cost of the reactor 1.

[0059] Exemplarily, the sludge discharging assembly 6 comprises a sludge discharging pipe and a sludge discharging valve connected to the sludge discharging pipe, one end of the sludge discharging pipe is communicated with the cyclone water inlet cavity 22, the other end of the sludge discharging pipe is communicated with the outside, and the sludge discharging valve is used to control the opening and closing of the sludge discharging pipe. However, it should be understood that the sludge discharging assembly 6 can also be any other suitable structure.

[0060] In an embodiment of the present application, as shown in Figure 1 , Figure 2 and Figure 3 , the hydraulic internal loop reactor comprises a slag discharging assembly 7, which is arranged at the inner wall surface of the reaction cavity 11, and the slag discharging port of the slag discharging assembly 7 is at least partially below the liquid level in the reaction cavity 11.

[0061] It can be understood that when the liquid flows into the reaction cavity 11 through the cyclone water outlet flow channel 31, a vortex flow is formed in the reaction cavity 11, which drives the floating slag at the liquid level to flow to the inner wall surface of the reaction cavity 11. When the floating slag moves to the slag discharging port, the floating slag flows out of the reaction cavity 11 through the slag discharging port, thereby achieving the cleaning of the floating slag in the reaction cavity 11. Moreover, the vortex flow automatically moves the floating slag to the slag discharging port, without the need for additional special slag discharging device to fish the floating slag, thereby simplifying the structure of the reactor 1 and reducing the manufacturing cost of the reactor 1.

[0062] Exemplarily, the slag discharging assembly 7 comprises a slag discharging pipe and a slag discharging valve connected to the slag discharging pipe, one end of the slag discharging pipe is located in the reaction cavity 11, the slag discharging port is formed at one end of the slag discharging pipe, the other end of the slag discharging pipe is located outside the reactor 1, and the slag discharging valve is used to control the opening and closing of the slag discharging pipe. However, it should be understood that the slag discharging assembly 7 can also be any other suitable structure.

[0063] In an embodiment of the present application, as shown in Figure 1 , Figure 2 and Figure 3 , the hydraulic internal loop reactor comprises a biogas pipeline 8, which is installed at the top of the reactor 1, communicated with the reaction cavity 11, and higher than the cyclone water outlet member 3.

[0064] It can be understood that when the liquid is injected into the reaction cavity 11, the liquid level in the reaction cavity 11 is kept at a normal liquid level, i.e. the liquid level is flush with or lower than the upper surface of the cyclone water outlet member 3. Moreover, the biogas pipeline 8 is higher than the cyclone water outlet member 3, i.e. there is a certain space between the biogas pipeline 8 and the liquid level, thereby enabling the biogas generated in the reaction cavity 11 to be discharged through the biogas pipeline 8, which is convenient for the utilization of the biogas.

[0065] In an embodiment of the present application, as shown in Figure 1 , Figure 2 andFigure 3 As shown, one end of the upflow passage 4 is inserted into the cyclone water inlet cavity 22, the other end of the upflow passage 4 extends upward, the other end of the upflow passage 4 is sequentially arranged in the cyclone water outlet cavity 32 and the through hole at the top of the reactor 1, the other end of the upflow passage 4 is located outside the reactor 1, and the other end of the upflow passage 4 is provided with a cover 41 and an exhaust valve, and the exhaust valve is adapted to communicate the upflow passage 4 with the outside.

[0066] It can be understood that when it is necessary to perform corresponding operations in the upflow passage 4, such as maintenance of the upflow pump 5, the liquid level in the reaction cavity 11 can be first raised so that the entire cyclone water outlet member 3 is below the liquid level, at this time, biogas will not enter the upflow passage 4, then the biogas in the upflow passage 4 is discharged through the exhaust valve, then the cover 41 is opened, and then the corresponding operation in the upflow passage 4 can be performed under the premise of safety, realizing that the upflow pump 5 can be maintained without stopping the reactor 1 and other operations.

[0067] It can be understood that after the maintenance of the upflow pump 5 and other operations are completed, the liquid in the reaction cavity 11 can be discharged through the slag discharge assembly 7, so that the liquid level in the reaction cavity 11 falls to the normal liquid level.

[0068] In an embodiment of the present application, the upflow pump 5 is movable relative to the upflow passage 4.

[0069] It can be understood that the upflow pump 5 is movably installed in the upflow passage 4, and then the upflow pump 5 can be taken out from the upflow passage 4 for maintenance, so that the maintenance operation is easier to perform.

[0070] For example, the inner wall surface of the upflow passage 4 is provided with a sliding rail, and the upflow pump 5 is installed on the sliding rail, so that the upflow pump 5 can move up and down relative to the upflow passage 4. However, it should be understood that the upflow pump 5 can also be movably connected to the upflow passage 4 by any other suitable means.

[0071] In an embodiment of the present application, as shown in Figure 1 The hydraulic internal loop reactor comprises a water level sensor 9 arranged in the reaction cavity 11, and the water level sensor 9 is adapted to detect the water level in the reaction cavity 11.

[0072] It can be understood that the water level in the reaction cavity 11 can be accurately known by the water level sensor 9, so as to accurately control the water level in the reaction cavity 11 to a corresponding height.

[0073] In an embodiment of the present application, the water outlets 33 of the cyclone water outlet members 3 are all directed towards the first direction, the inner wall surface of the reaction chamber 11 is provided with a plurality of pushers 12 and a plurality of first gas delivery members, the pushers 12 and the first gas delivery members are all located below the liquid surface in the reaction chamber 11, the pushers 12 and the first gas delivery members are spaced apart along the circumference of the reactor 1, the pushers 12 are adapted to drive the liquid in the reaction chamber 11 to rotate along the first direction, and the first gas delivery members are adapted to deliver gas towards the first direction.

[0074] It can be understood that when the liquid flows from the water outlets 33 of the cyclone water outlet members 3 into the reaction chamber 11, the liquid will drive the water in the reaction chamber 11 to rotate along the first direction, forming a vortex flow rotating along the first direction. At the same time, the pushers 12 will drive the liquid in the reaction chamber 11 to rotate towards the first direction, further enhancing the strength of the vortex flow in the reaction chamber 11, improving the mixing and stirring effect. At the same time, the first gas delivery members will deliver gas towards the first direction, and when the gas moves along the first direction, it will also enhance the rotation of the vortex flow in the reaction chamber 11, and at the same time, the gas will form bubbles in the liquid, which will move upwards, further increasing the mixing effect of the solution in the reaction chamber 11.

[0075] For example, the gas delivered by the first gas delivery members is biogas.

[0076] For example, one end of the first gas delivery members is arranged above the cyclone water outlet members 3, and the other end of the first gas delivery members is located below the liquid surface in the reaction chamber 11, so that the first gas delivery members use the biogas above the liquid surface in the reaction chamber 11 as the gas source.

[0077] In an embodiment of the present application, as shown in Figure 1 the hydraulic internal loop reactor comprises second gas delivery members 10, one end of the second gas delivery members 10 is arranged above the cyclone water outlet members 3, the other end of the second gas delivery members 10 is in communication with the upflow passage 4, and the second gas delivery members 10 are adapted to deliver biogas into the upflow passage 4.

[0078] It can be understood that the second gas delivery members 10 can deliver biogas into the upflow passage 4, thereby forming a bubble mixture in the upflow passage 4, and when the bubble mixture is delivered by the cyclone water outlet members 3 to the upper part of the reaction chamber 11, the bubbles in the bubble mixture will move upwards, thereby playing a role in disturbing the liquid and improving the mixing effect.

[0079] In an embodiment of the present application, one end of the upflow passage 4 is rotatably connected with the cyclone water inlet member 2, the other end of the upflow passage 4 is rotatably connected with the cyclone water outlet member 3, and the hydraulic internal loop reactor comprises a rotation driving member, the rotation driving member is connected with the upflow passage 4, and the rotation driving member is used to drive the upflow passage 4 to rotate.

[0080] It can be understood that the upflow pump 5 makes the liquid at the bottom of the reaction cavity 11 enter the cyclone water inlet cavity 22 after passing through the cyclone water inlet channel 21. The liquid forms a vortex flow rotating along the first direction after passing through the cyclone water inlet channel 21. When the vortex flow moves to the cyclone water outlet part 3 along the upflow channel 4, the rotating driving part drives the upflow channel 4 to rotate along the first direction, so that the liquid in the upflow channel 4 remains in the vortex flow state, ensuring that the liquid is transported to the cyclone water outlet part 3 in the vortex flow state.

[0081] In the embodiment of the present application, the outer wall surface of the upflow channel 4 is provided with a plurality of stirring blades.

[0082] It can be understood that when the rotating driving part drives the upflow channel 4 to rotate, the stirring blades will rotate together in the first direction, thereby driving the solution in the reaction cavity 11 to rotate in the first direction, enhancing the vortex flow in the reaction cavity 11 and improving the mixing and stirring effect.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the present application, but not to limit the present application. Although the present application is described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present application do not deviate from the spirit and scope of the present application, and should be covered in the scope of the claims of the present application.
