Description

Technical Field

[0001] The present invention relates to the technical field of tubular membrane processing, and in particular to a high-efficiency tubular membrane device and method for multiphase material separation and thermal upgrading. Background Art

[0002] Membrane separation technology, based on diffusion mechanisms, is a core approach in the field of gas separation. It exploits differences in the diffusion rates of gas molecules within membrane materials to achieve separation. Tubular membrane modules, due to their high mechanical strength and strong resistance to contamination, are widely used in the treatment of volatile organic compound (VOC)-containing waste gases and natural gas decarbonization. Existing technologies primarily rely on organic polymer membranes or inorganic molecular sieve membranes to separate gas components through molecular size screening or dissolution-diffusion mechanisms.

[0003] However, existing devices and methods for multiphase material separation and thermal upgrading still have related problems. For example, when the tubular membrane is severely contaminated and its performance cannot be restored through conventional cleaning, or when it is damaged, due to the lack of an effective mechanism for quickly replacing the tubular membrane, only tedious and time-consuming cleaning processes or slow maintenance work can be carried out. This significantly prolongs the downtime of the device and greatly affects the continuity of production. For those companies with high requirements for production efficiency, it will cause large economic losses and fail to meet their needs for efficient production. Summary of the Invention

[0004] The object of the present invention is to provide a high-efficiency tubular membrane device and method for multiphase material separation and thermal upgrading, so as to solve the above-mentioned deficiencies in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency tubular membrane device for multiphase separation and thermal upgrading, comprising a main unit, one end of which is provided with a pipe and a tubular membrane connected thereto, and further comprising:

[0007] The air intake switching unit is arranged between tubular membrane 1 and tubular membrane 2, and is connected to an air intake pipe at the end away from the installation end of the tubular membrane. When tubular membrane 1 is blocked and the air pressure in its air intake channel is too high, the piston in the air intake switching unit is pressed downward, and the air intake guide toward tubular membrane 1 is converted to tubular membrane 2, and the reset sleeve slidably installed on one side of the air intake switching unit is driven to disengage from tubular membrane 1 until the reset sleeve is locked with the inside of the air intake switching unit.

[0008] As a further description of the above technical solution: the air intake switching unit includes a pipe three connected to the second flange of the tubular membrane, the upper end of the pipe three is interconnected with an exhaust box, a cylinder is fixed on one side of the exhaust box, and the cylinder is provided with exhaust ports that are interconnected on the side facing the exhaust box, the piston slides on the inner wall of the cylinder, and a compression spring is connected between the piston and the bottom wall inside the cylinder.

[0010] As a further description of the above technical solution: the closing assembly includes a fixed plate fixed to the inner wall of the air intake box and a closing plate locked and slidably connected to the fixed plate, and the closing plate and the piston are connected by an L-shaped rod. When the piston slides down under the action of air pressure, it drives the closing plate to move down and cooperate with the fixed plate to close the internal channel of the air intake box.

[0011] As a further description of the above technical solution: the stretching assembly includes a guide rod connected to the closing plate, and a chute plate is slidably installed between the upper and lower walls of the air inlet box. The end of the guide rod passes through the inclined groove on the chute plate and slides directionally along its track. The other end of the chute plate is fixed to the reset sleeve through a connecting rod. When the closing plate moves downward, the guide rod drives the chute plate to move horizontally, and then pulls back the reset sleeve to separate it from the tubular membrane.

[0012] As a further description of the above technical solution: the locking assembly includes an elastic stretching rod fixed to the lower part of the air intake box, the elastic stretching rod is composed of a stretching spring and a pull rod sleeve, wherein one end of the stretching spring is fixed to the lower outer wall of the air intake box, and the other end is connected to the pull rod sleeve.

[0013] As a further description of the above technical solution: the top end of the pull rod sleeve passes through the lower wall of the air intake box and is fixed with a bevel block, and the bevel slot plate is fixed with an L-shaped clamping rod on the side close to the bevel block. When the bevel slot plate is pulled back under force, the L-shaped clamping rod moves in accordance with the inclined surface of the bevel block, and the tension spring is stretched under force and completes the locking of the L-shaped clamping rod and the bevel block through subsequent resetting action.

[0014] As a further description of the above technical solution: one side of the elastic stretching rod is connected to an arc-shaped baffle through a Z-shaped rod.

[0016] A high-efficiency tubular membrane device for multiphase separation and thermal upgrading, the method of using the device is as follows:

[0017] S1: Multiphase separation: Multiphase gas is pumped into the tubular membrane through the inlet channel. The multiphase gas diffuses freely inside the tubular membrane. Different gases partially penetrate the membrane and are separated by diffusion according to their characteristics.

[0018] S2: Thermal upgrading: The separated materials flow to the thermal upgrading area, where they are heated by heating equipment to a specific temperature, triggering a thermal upgrading reaction.

[0020] S4: Air intake switching: When the internal air pressure of the air intake box gradually increases due to the blockage of tubular membrane 1, the piston inside the cylinder moves downward and drives the sealing component to gradually close the internal channel of the exhaust box and simultaneously open the channel to tubular membrane 2;

[0021] S5: Replacement without stopping the machine: While the piston moves downward, the reset sleeve is first pulled back by the stretching assembly to separate it from the tubular membrane 1. The locking assembly then positions the reset sleeve. The relevant staff reinserts the replaced tubular membrane and releases the reset sleeve by pulling the locking assembly to reconnect it with the newly replaced tubular membrane. At the same time, the air inlet channel of tubular membrane 2 is switched back to tubular membrane 1.

[0022] In the above technical solution, the present invention provides a high-efficiency tubular membrane device and method for multiphase material separation and thermal upgrading, which has the following beneficial effects:

[0023] 1. The device is equipped with tubular membrane 2 and an air inlet switching unit. When tubular membrane 1 is blocked and the air pressure in the air inlet channel is too high, the air inlet switching unit can automatically switch the air inlet guide from tubular membrane 1 to tubular membrane 2. During this process, the piston is pressed downward to change the air inlet direction, and at the same time drives the reset sleeve to disengage from tubular membrane 1 and lock with the inside of the air inlet switching unit. When tubular membrane 1 is blocked, the device can still use tubular membrane 2 to continue multiphase material separation and thermal quality improvement, avoiding the entire device from stopping due to the blockage of a certain tubular membrane. This greatly improves the stability and continuity of the device operation, reduces production interruptions caused by equipment failures, and ensures the smooth progress of the production process.

[0024] 2. The components of the device have strong linkage. When tubular membrane 1 is blocked, the intake pressure increases, triggering the action of the intake switching unit. The piston moves downward, switching the intake guide from tubular membrane 1 to tubular membrane 2 while driving multiple components to work together. The piston drives the closing plate downward through the L-shaped rod to close the intake channel; the closing plate drives the guide rod to move the chute plate horizontally, and the resetting ferrule is pulled back and disengaged from tubular membrane 1 through the connecting rod. This linkage design automatically assists in disassembling the blocked tubular membrane while switching the airflow channel to ensure work continuity, reducing the difficulty and time cost of manual operation, and improving the operating efficiency and maintenance convenience of the device.

DETAILED DESCRIPTION

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] See also Figures 1-8 The embodiment of the present invention provides a high-efficiency tubular membrane device for multiphase separation and thermal upgrading, comprising a main unit 1, one end of which is provided with a pipe 2 and a tubular membrane 4 connected thereto, and further comprising:

[0038] Tubular membrane 2 5, arranged on the same side of main unit 1 and tubular membrane 1 4 and connected via pipe 2 3;

[0039] The air inlet switching unit 6 is arranged between the tubular membrane 1 4 and the tubular membrane 2 5, and is connected to an air inlet pipe away from the installation end of the tubular membrane. When the tubular membrane 1 4 is blocked and the air pressure in its air inlet channel is too high, the piston 61 in the air inlet switching unit 6 is pressed down, and the air inlet guide toward the tubular membrane 1 4 is converted to the tubular membrane 2 5, and the reset sleeve 7 slidably installed on one side of the air inlet switching unit 6 is driven to separate from the tubular membrane 1 4 until the reset sleeve 7 is locked with the inside of the air inlet switching unit 6. During normal operation, multiphase gas enters the inlet from the inlet pipe. After the gas switching unit 6, the gas flows to the tubular membrane 4 for multiphase material separation and thermal upgrading. When the tubular membrane 4 is blocked, the air pressure in the air inlet channel increases, and the piston 61 moves downward under the action of the air pressure to overcome the elastic force of the compression spring 65, causing the air inlet channel to change direction and the gas to flow to the tubular membrane 2 5. At the same time, the downward movement of the piston 61 drives the relevant components to move, so that the reset sleeve 7 is separated from the tubular membrane 4 and locked with the inside of the air inlet switching unit 6, realizing the switching of the air inlet guide and the isolation of the tubular membrane 4, which is convenient for the subsequent treatment of the blocked tubular membrane 4.

[0040] In another embodiment provided by the present invention, the air intake switching unit 6 includes a pipe three 62 connected to the tubular membrane second 5 flange, the upper end of the pipe three 62 is interconnected with an exhaust box 63, a cylinder 64 is fixed on one side of the exhaust box 63, and the cylinder 64 is provided with mutually penetrating exhaust ports on the side facing the exhaust box 63, the piston 61 fits and slides on the inner wall of the cylinder 64, a compression spring 65 is connected between the piston 61 and the bottom wall of the cylinder 64, an air intake box 66 is fixed on the top of the cylinder 64, a sealing component 67 connected to the piston 61 is provided inside the air intake box 66, and a stretching group that drives the resetting sleeve 7 to extend and retract is connected to one side of the sealing component 67 A locking assembly 69 that can be engaged with each other is provided between the component 68, the stretching assembly 68 and the air inlet box 66; when the air inlet switching unit 6 normally intakes air to the tubular membrane 4, the piston 61 is in a normal position in the cylinder 64 under the support of the compression spring 65. At this time, the exhaust port on the exhaust box 63 is normally exhausted to balance the air pressure in the system. The air inlet channel of the air inlet box 66 is unobstructed, and the gas flows to the tubular membrane 4. When the tubular membrane 4 is blocked and the air pressure rises, the piston 61 moves downward, the compression spring 65 is compressed, and the downward movement of the piston 61 drives the closing assembly 67 and the stretching assembly 68 to operate, and also affects the state change of the locking assembly 69.

[0041] In another embodiment provided by the present invention, the sealing assembly 67 includes a fixed plate 671 fixed to the inner wall of the air inlet box 66 and a sealing plate 672 that is locked and slidably connected to the fixed plate 671, and the sealing plate 672 is connected to the piston 61 by an L-shaped rod. When the piston 61 slides down under the action of air pressure, it drives the sealing plate 672 to move down and cooperate with the fixed plate 671 to close the internal channel of the air inlet box 66; when the piston 61 moves downward, the L-shaped rod drives the sealing plate 672 to slide downward along the fixed plate 671. When the sealing plate 672 slides down to a certain position, it cooperates tightly with the fixed plate 671 to block the internal channel of the air inlet box 66, thereby preventing the gas from continuing to flow to the tubular membrane 4.

[0042] It is worth noting that the cross-section of the groove of the fixed plate 671 facing the closing plate 672 is T-shaped, and the closing plate 672 is provided with a T-shaped block that slides directionally along the inside of the T-shaped groove. Due to the design of the T-shaped structure, the closing plate 672 can vertically fit the fixed plate 671 and slide up and down stably.

[0043] In another embodiment provided by the present invention, the stretching assembly 68 includes a guide rod 681 connected to the closing plate 672, and a chute plate 682 is slidably installed between the upper and lower walls of the air inlet box 66, the end of the guide rod 681 passes through the inclined groove on the chute plate 682 and slides directionally along its track, and the other end of the chute plate 682 is fixed to the reset sleeve 7 through a connecting rod. When the closing plate 672 moves downward, the guide rod 681 drives the chute plate 682 to move horizontally, and then pulls back the reset sleeve 7 to separate it from the tubular membrane 14; during the downward movement of the closing plate 672, the guide rod 681 connected thereto also moves downward. Since the end of the guide rod 681 is in the inclined groove of the chute plate 682, according to the guiding effect of the chute, the chute plate 682 will move horizontally between the upper and lower walls of the air inlet box 66, and through the connection of the connecting rod, the chute plate 682 moves horizontally to pull back the reset sleeve 7, so that the reset sleeve 7 is separated from the connection position of the tubular membrane 14.

[0044] It is worth noting that the guide rod 681 is specifically a Z-shaped structure, which makes it easier to press down and pull back the inclined slot plate 682, and sliders are provided at the upper and lower ends of the inclined slot plate 682, and slide bars are provided on the upper and lower inner walls of the air intake box 66. The slide bars are provided with slide grooves for directional sliding of the sliders, so that the inclined slot plate 682 can slide stably inside the air intake box 66, and because the inclined slot plate 682 is fixed to the reset sleeve 7 by a connecting rod, and the interior of the reset sleeve 7 is set to a cavity structure that fits the air intake box 66, the reset sleeve 7 can slide and slide in a directional manner in accordance with the outer wall of the air intake box 66.

[0045] In another embodiment provided by the present invention, the locking assembly 69 includes an elastic stretching rod 691 fixed to the lower part of the air intake box 66, and the elastic stretching rod 691 is composed of a stretching spring and a pull rod sleeve, wherein one end of the stretching spring is fixed to the lower outer wall of the air intake box 66, and the other end is connected to the pull rod sleeve, and the top of the pull rod sleeve passes through the lower wall of the air intake box 66 and is fixed with an inclined block 692, and the inclined slot plate 682 is fixed with an L-shaped clamping rod 693 on the side close to the inclined block 692. When the inclined slot plate 682 is pulled back by force, the L-shaped clamping rod 693 moves in accordance with the inclined surface of the inclined block 692, and the stretching spring is stretched by force and completes the locking of the L-shaped clamping rod 693 and the inclined block 692 through the subsequent resetting action. One side of the elastic stretching rod 691 is connected by a Z-shaped rod There is an arc-shaped baffle 8, which is located inside the exhaust box 63 and fits into the upper part of the exhaust port set thereon. The middle section of the Z-shaped rod passes through the exhaust box 63 and slides up and down; during the pulling back of the inclined slot plate 682, the L-shaped clamping rod 693 slides along the inclined surface of the inclined block 692, and the tension spring is stretched. When the L-shaped clamping rod 693 slides to the appropriate position, the tension spring resets and clamps the L-shaped clamping rod 693 with the inclined block 692 to achieve locking. At this time, the reset sleeve 7 is stably locked in the position connected to the inside of the air intake switching unit 6. At the same time, when the elastic stretching rod 691 is actuated, the arc-shaped baffle 8 is driven by the Z-shaped rod to slide up and down in the exhaust box 63, and the exhaust volume of the exhaust port is adjusted to a certain extent to adapt to the changes in the system air pressure.

[0046] It is worth noting that when the device is in the stage of tubular membrane 1-4 intake, the multiphase gas flows into the main unit 1 of the device through the air intake box 66, tubular membrane 1-4, and pipeline 1-2. When the tubular membrane 1-4 is blocked, the air pressure increases and squeezes the piston 61. The piston 61 gradually moves downward. Before the piston moves downward, the piston as a whole blocks the air port connected between the cylinder 64 and the exhaust box 63, and gradually opens the air port channel during the downward movement, thereby increasing the exhaust rate. With the corresponding closure of the air intake box 66, the multiphase gas passes through the air intake box 66, the cylinder 64, the exhaust box 63, the pipeline 3 62, the tubular membrane 2 5, and the pipeline 2 3 into the interior of the main unit 1, forming a new multiphase gas separation process. The air pressure in the air inlet box 66 is always in an increasing state during this process, so that the piston 61 can continue to press down and squeeze the compression spring 65. However, as the air port continues to expand, the rate of increase of the air pressure gradually slows down, and the downward movement rate of the piston 61 becomes slower and slower until the L-shaped clamping rod 693 and the inclined block 692 are locked with each other. At the moment of locking, the end of the L-shaped clamping rod 693 moves downward from the highest point of the inclined block 692, thereby driving the arc-shaped baffle 8 to move downward synchronously, further opening the upper air port connected between the cylinder 64 and the exhaust box 63, and the air port expands rapidly. At this time, the outflow of the air inlet box 66 is greater than the inflow of the air, which is equivalent to internal pressure relief of the air inlet box 66.

[0047] Based on the above-mentioned air pressure changes, after the staff completes the reinsertion and replacement of the tubular membrane 4, they manually pull down the elastic stretching rod 691. The inclined block 692 loses its locking force and there is not enough air pressure support inside the air inlet box 66. As a result, the piston 61 is driven to rise and reset quickly through the compression spring 65, and the closing plate 672 rises and opens accordingly, completing the second switching of the air flow channel. At the same time, under the linkage action of the stretching assembly 68, the reset sleeve 7 also completes the replacement of the tubular membrane with the switching of the air flow channel, thereby completing the insertion and positioning of the end flange and quickly completing the assembly.

[0048] In another embodiment provided by the present invention, the reset sleeve 7 is provided with multiple sets of insertion rods (I) at the end away from the air inlet box 66, and multiple sets of insertion rods (II) are provided on the flange of pipe (2). The insertion rods (I) and (II) are capable of correspondingly inserting into the flange holes on either side of the tubular membrane (4). During installation and normal operation of the device, the insertion rods (I) of the reset sleeve 7 and the insertion rods (II) on the flange of pipe (2) are correspondingly inserted into the flange holes on either side of the tubular membrane (4), firmly connecting the tubular membrane (4) to the device. When it is necessary to switch the air inlet guide or perform processing on the tubular membrane (4), as in the above process, the reset sleeve 7 is pulled back out of the flange holes on either side of the tubular membrane (4).

[0049] A high-efficiency tubular membrane device for multiphase separation and thermal upgrading, the method of using the device is as follows:

[0050] S1: Multiphase separation: Multiphase gas is pumped into the tubular membrane 4 through the inlet channel by an external air pump. The multiphase gas diffuses freely inside the tubular membrane 4, and different gases partially penetrate the membrane for diffusion separation according to their characteristics.

[0051] S2: Thermal upgrading: The separated materials flow to the thermal upgrading area, where they are heated by heating equipment to a specific temperature, triggering a thermal upgrading reaction.

[0052] S3: Discharging: The materials after separation and thermal upgrading are discharged from the device through different discharge ports;

[0053] S4: Air Inlet Switching: When the internal air pressure of the air inlet box 66 gradually increases due to the blockage of the tubular membrane 1 4, the piston 61 inside the cylinder 64 moves downward and drives the sealing assembly 67 to gradually close the internal passage of the exhaust box 63 and simultaneously open the passage to the tubular membrane 2 5;

[0054] S5: Replacement without stopping the machine: While the piston 61 moves downward, the stretching assembly 68 is used to pull back the reset sleeve 7 to separate it from the tubular membrane 1 4. The locking assembly 69 then positions the reset sleeve 7. The relevant staff reinserts the replaced tubular membrane and releases the reset sleeve 7 by pulling the locking assembly 69 to reconnect it with the newly replaced tubular membrane. At the same time, the air inlet channel of the tubular membrane 2 5 is switched back to the tubular membrane 1 4.

[0055] During specific operation: by turning on the external air pump, the multiphase gas is input into the tubular membrane 4 through the air inlet channel. The multiphase gas diffuses freely inside the tubular membrane 4. Due to the different characteristics of different gases, some gases will diffuse and separate through the membrane of the tubular membrane 4. The material separated by the tubular membrane 4 flows to the thermal upgrading area. At this time, the heating equipment starts to work, heating the material to a specific temperature, thereby initiating a thermal upgrading reaction. The material after separation and thermal upgrading is discharged from the device from different outlets.

[0056] When the tubular membrane 4 is blocked, the air pressure in the air inlet channel gradually increases, and the air pressure in the air inlet box 66 also increases accordingly. The increased air pressure in the air inlet box 66 presses the piston 61 inside the cylinder 64 downward, and the compression spring 65 is compressed. The piston 61 moves downward and drives the closing plate 672 in the closing assembly 67 to move downward through the L-shaped rod. The closing plate 672 cooperates with the fixed plate 671 to close the internal channel of the air inlet box 66. When the closing plate 672 moves downward, the guide rod 681 connected to it also moves downward, and the end of the guide rod 681 is inclined at the inclined groove plate 682. The inclined slot slides in the inclined slot, driving the inclined slot plate 682 to move horizontally. The inclined slot plate 682 moves horizontally and pulls back the reset sleeve 7 through the connecting rod, so that the reset sleeve 7 is separated from the tubular membrane 4. During the process of the inclined slot plate 682 being pulled back by force, the L-shaped clamping rod 693 on one side thereof moves in contact with the inclined surface of the inclined block 692, and the tension spring of the elastic tension rod 691 is stretched by force. When the L-shaped clamping rod 693 moves to the appropriate position, the tension spring completes the locking of the L-shaped clamping rod 693 and the inclined block 692 through the reset action. At this time, the reset sleeve 7 is locked with the inside of the air intake switching unit 6.

[0057] At the same time, the piston 61 moves downward, causing the air intake switching unit 6 to convert the air intake guide toward the tubular membrane 1 4 to the tubular membrane 2 5, and the multiphase gas enters the tubular membrane 2 5 through the air intake pipe and the air intake switching unit 6 for subsequent processes such as multiphase material separation, thermal quality improvement and discharging. During the downward movement of the piston 61, the arc-shaped baffle 8 slides up and down in the exhaust box 63 through the Z-shaped rod along with the action of the elastic stretching rod 691, and the exhaust port on the exhaust box 63 is correspondingly blocked and adjusted.

[0058] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.

The insertion rods 1 and 2 can be correspondingly inserted into the flange holes on both sides of the tubular membrane 1 (4).

10. A high-efficiency tubular membrane device for multiphase separation and thermal upgrading according to any one of claims 1 to 9, characterized in that: The method of using the device is: S1: Multiphase material separation: Multiphase gas is input into the tubular membrane 1 (4) through the air inlet channel by an external air pump. The multiphase gas diffuses freely inside the tubular membrane 1 (4). Different gases partially penetrate the membrane for diffusion separation according to their characteristics. S2: Thermal upgrading: The separated materials flow to the thermal upgrading area, where they are heated by heating equipment to a specific temperature, triggering a thermal upgrading reaction. S3: Discharging: The materials after separation and thermal upgrading are discharged from the device through different discharge ports; S4: Air intake switching: When the internal air pressure of the air intake box (66) gradually increases due to the blockage of the tubular membrane 1 (4), the piston (61) inside the cylinder (64) moves downward and drives the sealing component (67) to gradually close the internal channel of the exhaust box (63) and simultaneously open the channel leading to the tubular membrane 2 (5); S5: Replacement without stopping the machine: While the piston (61) is moving downward, the reset sleeve (7) is first pulled back by the stretching assembly (68) to separate it from the tubular membrane 1 (4), and the locking assembly (69) then positions the reset sleeve (7). The relevant staff reinserts the replaced tubular membrane and releases the reset sleeve (7) by pulling the locking assembly (69) to reconnect it with the newly replaced tubular membrane. At the same time, the air inlet channel of the tubular membrane 2 (5) is then switched back to the tubular membrane 1 (4).
