Description

Technical Field

[0001] The present invention relates to the technical field of industrial wastewater treatment, and in particular to an IC reactor blockage clearing device and method. Background Art

[0002] Anaerobic biological treatment is widely used in my country for high-concentration, difficult-to-degrade industrial organic wastewater. Due to concerns about biogas capture and safety, the IC reactor was developed to address the anaerobic reaction of wastewater, as well as the three-phase separation and gas collection after the reaction. The IC reactor injects wastewater into the bottom of the reactor, where mixing, reaction, gas capture, precipitation, and gas collection occur from bottom to top, achieving gas-liquid-solid separation. In the gas-liquid separation tank, where the gas is collected, the gas-liquid mixture entering the reactor is separated by its own characteristics. The gas rises and is discharged from the gas outlet, while the liquid returns to the bottom of the reactor through the internal circulation pipe to participate in the reaction.

[0003] The mixture entering the gas-liquid separation tank will inevitably contain small solid particles or flocs. During the IC reaction process, they will precipitate and adhere to the internal circulation pipe. Over time, the internal circulation pipe will be blocked, and the circulation pipe needs to be cleared and maintained.

[0004] With respect to the above-mentioned related technologies, the inventors found that currently, the blockage treatment of the circulation pipe in the IC reactor is mostly done manually, which is time-consuming and labor-intensive. Moreover, the IC reactor is shut down for a long time, affecting the production progress. Summary of the Invention

[0005] In view of this, the present invention provides an IC reactor blockage clearing device and method, which facilitates the clearing of IC reactor blockage and ensures stable operation of the reactor.

[0006] A blockage clearing device for an IC reactor comprises a liquid-gas separation tank located on the upper part of the IC reactor and capturing anaerobic tail gas, and a reaction tank for performing liquid-gas separation, wherein an internal circulation pipe is provided in the reaction tank, and further comprises: a blockage clearing mechanism arranged on one side of the liquid-gas separation tank, wherein the blockage clearing mechanism absorbs the liquid in the liquid-gas separation tank and pressurizes and transports the absorbed liquid into the internal circulation pipe to clear the blockage in the internal circulation pipe.

[0007] The blockage clearing mechanism includes a water pump arranged on one side of the liquid-gas separation tank, the water outlet pipe of the water pump is connected to the top of the internal circulation pipe, and the water suction pipe of the water pump is connected to the tank body of the liquid-gas separation tank.

[0008] By adopting the above technical solution, when the internal circulation pipe of the IC reactor is blocked, the liquid level in the liquid-gas separation tank rises, and the water pump sucks the liquid in the liquid-gas separation tank through the suction pipe and pressurizes it into the internal circulation pipe, thereby pressure-clearing the internal circulation pipe and clearing the blockage.

[0009] Openings are provided on both sides of the inner circulation pipe, and the openings are located at the upper part of the inner circulation pipe, so that the liquid in the liquid-gas separation tank returns to the bottom of the IC reactor from the inner circulation pipe.

[0010] Under normal operation, the IC reactor receives a mixture from the first and second collection zones through the riser tube into the liquid-gas separation tank. Due to its inherent characteristics, the gas is discharged through the gas outlet pipe at the top of the liquid-gas separation tank, while the liquid is discharged back into the IC reactor mixing zone through the inner circulation tube. Openings are provided on both sides of the inner circulation tube to ensure that the liquid can be smoothly discharged from the inner circulation tube back into the IC reactor mixing zone, achieving liquid-gas separation.

[0011] Preferably, an IC reactor blockage clearing device also includes: a floating and sinking mechanism, which is arranged in the upper part of the liquid-gas separation tank; a sliding tube mechanism, which is arranged in the liquid-gas separation tank, located at the lower part of the floating and sinking mechanism, and can move up and down under the drive of the floating and sinking mechanism; a tightening mechanism, which is arranged on one side of the sliding tube to stop the sliding tube mechanism.

[0012] When the IC reactor is blocked, the floating mechanism rises within the gas-liquid separator tank due to buoyancy, driving the sliding tube mechanism upward. After the sliding tube mechanism rises, it closes the openings on both sides of the inner circulation tube, facilitating the pump to pressurize and deliver liquid into the inner circulation tube through the outlet pipe to clear the blockage. Once the sliding tube mechanism rises to the appropriate position, the tightening mechanism secures the sliding tube. Once the blockage is cleared, the floating mechanism descends under its own gravity, driving the sliding tube mechanism downward. The floating mechanism and sliding tube mechanism return to their initial positions, opening the openings on both sides of the inner circulation tube. The liquid in the gas-liquid separator tank flows into the mixing zone through the openings on both sides of the inner circulation tube, and the tightening mechanism positions the sliding tube.

[0013] The floating and sinking mechanism includes: a floating plate, which is arranged in the cavity at the upper part of the liquid-gas separation tank; a baffle, which is an annular structure, which is arranged on the inner wall of the liquid-gas separation tank and is located below the floating plate; a spring A, which is fixedly installed at the lower part of the floating plate and connected to the sliding pipe mechanism.

[0014] When the IC reactor becomes blocked, the liquid level in the liquid-gas separation tank rises, allowing the float to rise due to buoyancy. Once the blockage is cleared, the liquid level in the liquid-gas separation tank drops, and the float descends to its original position under its own gravity. The retaining platform supports the float; spring A connects to the sliding tube mechanism. The advantage of having spring A here is that it ensures a certain degree of elastic deformation, allowing the clearing device to be activated only when the blockage is severe.

[0015] The sliding tube mechanism includes: a sliding tube, which is arranged at the bottom of the liquid-gas separation tank, and the sliding tube is sleeved on the upper part of the inner circulation tube. Driven by the floating plate, it can move up and down to close or open the openings on both sides of the inner circulation tube; a sliding tube hook, which is arranged on the inner side of the upper end surface of the sliding tube and is connected to the spring A through a connecting rope.

[0016] Spring A connects to the sliding pipe hook via a connecting rope, which in turn connects to the sliding pipe. The upward and downward movement of the floating plate drives the sliding pipe upward. When the internal circulation pipe becomes clogged, the floating plate rises, driving the sliding pipe upward, sealing the openings on both sides of the pipe. The blockage-clearing mechanism then activates to clear the blockage. Once the blockage is cleared, the floating plate descends, driving the sliding pipe downward, opening the openings on both sides of the pipe and restoring the initial operating state.

[0017] The tightening mechanism includes: a mounting hole, which is arranged at the upper part of the bottom of the liquid-gas separation tank and is located on one side of the bottom of the liquid-gas separation tank; a spring pin, which is arranged in the mounting hole; an upper top hole, which is arranged at the upper part of the sliding tube; and a lower top hole, which is arranged at the lower part of the sliding tube; the upper top hole and the lower top hole correspond to the positions of the mounting hole, ensuring that the spring pin can be stuck in the upper top hole or the lower top hole after popping out in the mounting hole.

[0018] A mounting hole is provided at the bottom of the liquid-gas separation tank, and a spring pin is provided in the mounting hole. An upper top hole and a lower top hole are provided on the sliding tube. When the IC reactor is operating normally, the spring pin pops out of the mounting hole and presses against the upper top hole. During the rising process of the sliding tube, the spring pin is squeezed into the mounting hole. When the sliding tube rises to a certain height, the lower top hole and the mounting hole are aligned, and the spring pin pops out again to stop and position the sliding tube.

[0019] The floating plate is provided with a plurality of circular holes, the bottom of the floating plate is provided with a floating plate hole for connecting the spring A, and a top rod is fixedly provided on one side of the floating plate hole at the bottom of the floating plate.

[0020] A circular hole is provided on the floating plate to allow gas to pass through and realize liquid-gas separation. A floating plate hole is provided in the middle of the bottom of the floating plate for connecting spring A. A push rod is provided on one side of the floating plate hole. When the blockage is cleared, the floating plate descends and the push rod pushes the sliding tube downward.

[0021] A guide plate is provided on the inner wall of the liquid-gas separation tank. The guide plate is located on the upper part of the baffle. The floating plate can move up and down along the guide plate.

[0022] Four guide plates can be provided, and corresponding floating plates are also provided with grooves for installing the guide plates, so as to ensure that the floating plates float upward steadily under the buoyancy of the liquid surface.

[0023] Preferably, the sliding tube mechanism also includes a step, which is arranged on the upper part of the inner circulation tube, and a touch switch is provided at the lower part of the step, and the touch switch is electrically connected to the water pump to control the operation of the water pump. The step is located at the upper end of the openings on both sides of the inner circulation tube; a spring B is arranged at the bottom of the sliding tube.

[0024] A step is provided at the upper part of the inner circulation pipe, and a touch switch is provided at the lower part of the step. The touch switch is electrically connected to the water pump. When the sliding pipe rises, it hits the touch switch, starts the water pump to start working, and clears the blockage in the inner circulation pipe; when the blockage is cleared, the sliding pipe descends, the touch switch is closed, and the water pump stops working.

[0025] The bottom of the liquid-gas separation tank is provided with a stepped cylindrical structure, and the inner circulation pipe is provided inside the stepped cylindrical structure and can move up and down the bottom of the liquid-gas separation tank.

[0026] The circumference of the sliding tube is located opposite to the position of the lower top hole and has a key-shaped protrusion. The bottom of the liquid-gas separation tank is provided with a tank bottom groove that cooperates with the protrusion. During installation, the protrusion cooperates with the tank bottom groove to prevent the sliding tube from rotating relative to the installation part of the bottom of the liquid-gas separation tank.

[0027] A method for clearing blockage in an IC reactor uses the above-mentioned IC reactor clearing blockage device.

[0028] Preferably, the method for clearing blockage in an IC reactor comprises the following steps:

[0029] S1: When the inner circulation pipe is blocked, the liquid level in the liquid-gas separation tank slowly rises, lifting the float plate, which floats upward along the guide plate, driving spring A. Spring A slowly tightens the connecting rope, and the elastic force acts on the sliding pipe through the tightened connecting rope. When the elastic force is greater than the friction force of the spring pin on the sliding pipe, the spring pin is pressed back into the mounting hole at the bottom of the liquid-gas separation tank. Under the action of the elastic force accumulated by spring A, the sliding pipe slides upward quickly until it hits the step where the touch switch is located, closing the openings on both sides of the inner circulation pipe. After the sliding pipe moves, spring B moves from the initial state to the stretched position, and the spring pin just blocks the lower top hole. The elastic force of spring B is less than the friction force of the spring pin on the lower top hole, and the sliding pipe is locked at this time.

[0030] S2: After the touch switch is pressed, the clearing device starts to operate, the water pump starts, and pressurized water is delivered to the inner circulation pipe behind the sliding pipe seal;

[0031] S3: Under the action of pressurized water, the blocked part of the internal circulation pipe is loosened and flushed back to the bottom of the IC reactor by the pressurized water;

[0032] S4: After the inner circulation pipe is unblocked, the water pump sucks water and discharges water. The liquid level in the liquid-gas reaction tank drives the float plate to gradually drop, and the push rod slowly supports the sliding pipe. At this time, the liquid level continues to drop, and the buoyancy received by the float plate gradually decreases. More and more of its own gravity acts on the sliding pipe through the push rod. When the sum of the elastic force of spring B and the pressure of the float plate on the sliding pipe is greater than the friction force of the spring pin on the lower top hole, the spring pin is pressed back, and the sliding pipe quickly returns to its initial position. The inner circulation pipe returns to normal working state, the spring pin hits the upper top hole, and spring B returns to its initial state. The trigger switch is released, the water pump stops working, and the liquid level in the gas-liquid separation tank will gradually drop in normal working state. The float plate eventually returns to the stop position, and the gas-liquid separation tank returns to its original working state and continues to work.

[0033] Compared with the prior art, the present invention has at least the following beneficial effects:

[0034] The IC reactor of the present invention comprises a liquid-gas separation tank and a reaction tank, which is equipped with an internal circulation pipe. During normal operation, the gas-liquid mixture entering through the riser is separated by its own characteristics, with the gas discharged through the exhaust pipe and the liquid returning to the bottom of the IC reactor through the internal circulation pipe. If the internal circulation pipe becomes blocked, the liquid level will continue to rise, and the buoyancy will lift the float plate to a certain height, triggering a mechanism to activate an external water pump, which uses the water pressure within the device to pressure-clear the internal circulation pipe, thereby clearing the blockage and ensuring the normal operation of the IC reactor.

[0035] A baffle is installed inside the gas-liquid separator tank to support the float plate. A guide plate is installed on the baffle to ensure that the float plate floats smoothly upward under the buoyancy of the liquid surface. Several circular holes are provided on the float plate to allow gas to pass through, and a float plate hole is provided at the bottom of the float plate for connecting to spring A. A sliding tube movement mechanism is installed at the bottom of the gas-liquid separator tank, including a sliding tube, a sliding tube hook, and spring B. The internal circulation tube is installed within the sliding tube. A mounting hole is provided on one side of the bottom of the gas-liquid separator tank, and a spring pin is provided in the mounting hole. The sliding tube has upper and lower top holes. In the initial state, the spring pin supports the upper top hole. When the internal circulation tube is blocked, the float plate moves upward, driving the sliding tube upward, and the spring pin supports the lower top hole. A water pump is installed on one side of the gas-liquid separator tank. The water pump's outlet pipe is connected to the top of the internal circulation tube, and the water pump's suction pipe is connected to the tank body of the gas-liquid separator tank. The water pump draws water from the tank through the suction pipe, pressurizes the water and delivers it to the drain pipe to clear the blockage in the internal circulation tube.

[0036] Compared to existing devices, the present invention can clear blockages in the internal circulation pipe when they become clogged, eliminating time-consuming and labor-intensive manual clearing. Compared to conventional active triggering methods, the present invention's blockage-clearing device features a self-feedback mechanism. When the liquid level drives the float plate upward, the pump activates the pump, utilizing the liquid within the device to clear the blockage, lowering the liquid level and, in turn, the float plate, restoring the float plate-driven mechanism to its initial state. This invention can reduce the maintenance complexity of IC reactors and improve their operational efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the appended drawings of the embodiments of the present invention. Figure 1-4 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments derived by ordinary technicians in this field fall within the scope of protection of the present invention.

[0045] Example 1

[0046] like Figure 1As shown, the IC reactor includes a liquid-gas separation tank 1 and a reaction tank. An internal circulation pipe 4 is provided in the reaction tank. From bottom to top, the reaction tank comprises a mixing zone 12, a first anaerobic zone 11, a first collection zone 10, a second anaerobic zone 9, and a second collection zone 8. An IC reactor water inlet pipe 5 is provided at the bottom of the reaction tank, and an IC reactor water outlet pipe 7 is provided at the top of the reaction tank. Rising pipes 3 are provided on both sides of the internal circulation pipe 4 in the reaction tank. The two rising pipes 3 have different lengths. The longer rising pipe 3 extends downward to the first collection zone 10, and the shorter rising pipe 3 extends downward to the second collection zone 8. The internal circulation pipe 4 extends downward to the mixing zone 12. The internal circulation pipe 4 and the rising pipe 3 both extend upward into the liquid-gas separation tank 1.

[0047] Under normal working conditions, the mixture of the IC reactor enters the liquid-gas separation tank 1 from the first collection area 10 and the second collection area 8 through the riser 3. Under the action of its own characteristics, the gas is discharged through the IC reactor outlet pipe 7, and the liquid is discharged back to the IC reactor mixing area 12 from the internal circulation pipe 4. The liquid level in the liquid-gas separation tank 1 remains at a normal position.

[0048] like Figure 1-4 As shown, this embodiment provides an IC reactor blockage clearing device, including a liquid-gas separation tank 1 located on the upper part of the IC reactor and capturing anaerobic tail gas, and a reaction tank for liquid-gas separation, wherein an internal circulation pipe 4 is provided in the reaction tank, and further comprising: a blockage clearing mechanism, which is arranged on one side of the liquid-gas separation tank 1, and the blockage clearing mechanism absorbs the liquid in the liquid-gas separation tank 1, and pressurizes and transports the absorbed liquid into the internal circulation pipe 4 to clear the blockage in the internal circulation pipe 4.

[0049] The blockage clearing mechanism includes a water pump 2 arranged on one side of the liquid-gas separation tank 1, the water outlet pipe 14 of the water pump 2 is connected to the top of the internal circulation pipe 4, and the water suction pipe 13 of the water pump 2 is connected to the tank body of the liquid-gas separation tank 1.

[0050] By adopting the above technical solution, when the internal circulation pipe 4 of the IC reactor is blocked, the liquid level in the liquid-gas separation tank 1 rises, the water pump 2 absorbs the liquid in the liquid-gas separation tank 1 through the water suction pipe 13, and pressurizes it into the internal circulation pipe 4, thereby pressure-clearing the internal circulation pipe 4 and clearing the blockage.

[0051] Openings are provided on both sides of the inner circulation pipe 4 , and the openings are located at the upper portion of the inner circulation pipe 4 , so that the liquid in the liquid-gas separation tank 1 returns to the bottom of the IC reactor from the inner circulation pipe 4 .

[0052] Under normal operating conditions, the IC reactor receives a mixture from the first collection zone 10 and the second collection zone 8 through the riser 3 into the liquid-gas separation tank 1. Due to its own characteristics, the gas is discharged through the gas outlet pipe at the top of the liquid-gas separation tank 1, and the liquid is discharged back to the IC reactor mixing zone 12 through the inner circulation pipe 4. Openings are provided on both sides of the inner circulation pipe 4 to ensure that the liquid can be smoothly discharged from the inner circulation pipe 4 back to the IC reactor mixing zone 12, achieving liquid-gas separation.

[0053] Example 2

[0054] This embodiment provides an IC reactor blockage clearing device, which is an improvement based on Example 1: it also includes: a floating and sinking mechanism, which is arranged in the upper part of the liquid-gas separation tank 1; a sliding tube 27 mechanism, which is arranged in the liquid-gas separation tank 1, located at the lower part of the floating and sinking mechanism, and can move up and down under the drive of the floating and sinking mechanism; a tightening mechanism, which is arranged on one side of the sliding tube 27 to stop the sliding tube 27 mechanism.

[0055] When the IC reactor is blocked, the floating mechanism can rise in the liquid-gas separation tank 1 due to the buoyancy, thereby driving the sliding tube 27 mechanism to rise. After the sliding tube 27 mechanism rises, it closes the openings on both sides of the inner circulation pipe 4, making it easier for the water pump 2 to pressurize and deliver the liquid into the inner circulation pipe 4 through the outlet pipe 14 to clear the blockage in the inner circulation pipe 4. When the sliding tube 27 mechanism rises to the appropriate position, the tightening mechanism fixes the sliding tube 27. When the blockage in the inner circulation pipe 4 is cleared, the floating mechanism descends under the action of its own gravity, thereby driving the sliding tube 27 mechanism to descend. The floating mechanism and the sliding tube 27 mechanism return to their initial positions, opening the openings on both sides of the inner circulation pipe 4. The liquid in the liquid-gas separation tank 1 flows into the mixing zone 12 through the openings on both sides of the inner circulation pipe 4, and the tightening mechanism positions the sliding tube 27.

[0056] The floating and sinking mechanism includes: a floating plate 16, which is arranged in the cavity at the upper part of the liquid-gas separation tank 1; a baffle 17, which is an annular structure, which is arranged on the inner wall of the liquid-gas separation tank 1 and is located below the floating plate 16; a spring A 18, which is fixedly installed at the lower part of the floating plate 16 and connected to the sliding tube 27 mechanism.

[0057] When the IC reactor becomes blocked, the liquid level in the separator tank 1 rises, allowing float plate 16 to rise due to buoyancy. Once the blockage is cleared, the liquid level in the separator tank 1 drops, and float plate 16 descends to its original position under its own weight. Stop 17 supports float plate 16; spring A 18 connects to the sliding tube 27 mechanism. The advantage of including spring A 18 here is that it ensures a certain degree of elastic deformation, allowing the clearing device to be activated only when the blockage is severe.

[0058] The sliding tube 27 mechanism comprises: a sliding tube 27 disposed on the bottom 26 of the liquid-gas separation tank. Sliding tube 27 is sleeved onto the upper portion of the inner circulation tube 4 and is driven by the floating plate 16 to move up and down, closing or opening the openings on either side of the inner circulation tube 4; and a sliding tube hook 22 disposed on the inner side of the upper end surface of the sliding tube 27 and connected to the spring A18 via a connecting rope 25. Three sliding tube hooks 22 are provided, evenly distributed on the inner side of the upper end surface of the sliding tube 27; however, other numbers are also possible.

[0059] Spring A 18 connects to the hook of sliding tube 27 via a connecting rope 25, which in turn connects to sliding tube 27. The upward and downward movement of floating plate 16 drives sliding tube 27 upward. When the inner circulation tube 4 becomes clogged, floating plate 16 rises, driving sliding tube 27 upward, sealing the openings on both sides of the inner circulation tube 4. The blockage-clearing mechanism then activates to clear the blockage. Once the blockage is cleared, floating plate 16 descends, driving sliding tube 27 downward, opening the openings on both sides of the inner circulation tube 4 and restoring the initial operating state.

[0060] The tightening mechanism includes: a mounting hole, which is provided at the upper part of the bottom 26 of the liquid-gas separation tank and is located on one side of the bottom 26 of the liquid-gas separation tank; a spring pin 28, which is provided in the mounting hole; an upper top hole, which is provided at the upper part of the sliding tube 27; and a lower top hole 29, which is provided at the lower part of the sliding tube 27; the upper top hole and the lower top hole 29 correspond to the positions of the mounting holes, ensuring that the spring pin 28 can be stuck in the upper top hole or the lower top hole 29 after popping out in the mounting hole. In the initial state, the sliding tube 27 is flush with the top surface of the bottom 26 of the liquid-gas separation tank, and the spring pin 28 presses against the upper top hole. The taper of the spring pin 28, the upper top hole, and the lower top hole 29 is greater than 90°, so that the spring pin 28 and the upper top hole / lower top hole 29 are easily disengaged.

[0061] A mounting hole is provided on the bottom 26 of the liquid-gas separation tank, and a spring pin 28 is provided in the mounting hole. At the same time, an upper top hole and a lower top hole 29 are provided on the sliding tube 27. When the IC reactor is operating normally, the spring pin 28 pops out from the mounting hole and presses against the upper top hole. During the rising process of the sliding tube 27, the spring pin 28 is squeezed into the mounting hole. When the sliding tube 27 rises to a certain height, the lower top hole 29 is aligned with the mounting hole, and the spring pin 28 pops out again to stop and position the sliding tube 27.

[0062] The floating plate 16 is provided with a plurality of circular holes. A hole for connecting the spring A18 is provided at the bottom of the floating plate 16. A push rod 19 is fixed to the bottom of the floating plate 16, located on one side of the hole. The length of the push rod 19 is less than or equal to the distance between the floating plate 16 and the sliding tube 27.

[0063] A circular hole is provided on the floating plate 16 to allow gas to pass through and realize liquid-gas separation. A floating plate 16 hole is provided in the middle of the bottom of the floating plate 16 for connecting the spring A18. A push rod 19 is provided on one side of the floating plate 16 hole. When the blockage is cleared, the floating plate 16 descends and the push rod 19 pushes the sliding tube 27 downward.

[0064] Example 3

[0065] This embodiment provides an IC reactor blockage clearing device, which is an improvement based on Example 2: a guide plate 15 is provided on the inner wall of the liquid-gas separation tank 1, and the guide plate 15 is located on the upper part of the baffle 17, and the floating plate 16 can move up and down along the guide plate 15.

[0066] Four guide plates 15 can be provided, and corresponding grooves for mounting the guide plates 15 are also provided on the floating plates 16 to ensure that the floating plates 16 float upward steadily under the buoyancy of the liquid surface.

[0067] The sliding tube mechanism also includes a step, which is arranged at the upper part of the inner circulation tube 4. A touch switch 21 is provided at the lower part of the step. The touch switch 21 is electrically connected to the water pump 2 to control the operation of the water pump 2. The step is located at the upper end of the openings on both sides of the inner circulation tube 4; a spring B23 is arranged at the bottom of the sliding tube 27 and can be connected to or not connected to the bottom 26 of the liquid-gas separation tank.

[0068] A step is provided at the upper part of the inner circulation pipe 4, and a touch switch 21 is provided at the lower part of the step. The touch switch 21 is electrically connected to the water pump 2. When the sliding tube 27 rises, it hits the touch switch 21, starts the water pump 2 to start working, and clears the blockage in the inner circulation pipe 4; when the blockage is cleared, the sliding tube 27 descends, the touch switch 21 is closed, and the water pump 2 stops working.

[0069] The bottom 26 of the liquid-gas separation tank is provided with a stepped cylindrical structure, and the inner circulation pipe 4 is provided inside the stepped cylindrical structure and can move up and down the bottom 26 of the liquid-gas separation tank. The inner circulation pipe 4 is provided inside the stepped cylindrical structure, and the inner circulation pipe 4 matches the inner wall shape of the stepped cylindrical structure.

[0070] The sliding tube 27 has a key-shaped protrusion on the opposite side of the lower top hole 29, and the bottom 26 of the liquid-gas separation tank is provided with a tank bottom groove 24 that cooperates with the protrusion. During installation, the protrusion cooperates with the tank bottom groove 24, so that the sliding tube 27 cannot rotate relative to the installation part of the liquid-gas separation tank bottom 26.

[0071] Example 4

[0072] This embodiment provides a method for clearing blockage in an IC reactor, using the IC reactor clearing blockage device of embodiment 3.

[0073] The method for clearing blockage in the internal circulation pipe of the IC reactor comprises the following steps:

[0074] S1: When the inner circulation pipe 4 is blocked, the liquid level in the gas-liquid separation tank 1 slowly rises, slowly lifting the float plate 16, and the float plate 16 floats upward along the guide plate 15, driving the spring A 18. The spring A 18 slowly tightens the connecting rope 25. As the liquid level drives the float plate 16 upward, the spring A 18 is gradually stretched, and the elastic force gradually increases. The elastic force acts on the sliding tube 27 through the tightened connecting rope 25. When the elastic force is greater than the friction force of the spring pin 28 on the sliding tube 27, the spring pin 28 is pressed back into the mounting hole 26 of the liquid-gas separation tank bottom. Under the action of the elastic force accumulated by the spring A 18, the sliding tube 27 slides upward quickly until it hits the step where the touch switch 21 is located, closing the openings on both sides of the inner circulation pipe 4. After the sliding tube 27 moves, the spring B 23 moves from the initial state to the stretched position, and the spring pin 28 just blocks the lower top hole 29. The spring B 23 elastic force is less than the friction force of the spring pin 28 on the lower top hole 29, and the sliding tube 27 is locked;

[0075] S2: After the touch switch 21 is pressed, the blockage clearing device starts to operate, the water pump 2 starts, and pressurizes water to the inner circulation pipe 4 after the sliding pipe 27 is sealed;

[0076] S3: Under the action of pressurized water, the blocked part of the inner circulation pipe 4 is loosened and flushed back to the bottom of the IC reactor by the pressurized water;

[0077] S4: After the inner circulation pipe 4 is unblocked, the water pump 2 absorbs water and discharges water. The liquid level in the liquid-gas reaction tank drives the float plate 16 to gradually descend, and the push rod 19 slowly supports the sliding tube 27. At this time, the liquid level continues to descend, and the buoyancy received by the float plate 16 gradually decreases. The gravity of the float plate 16 acts on the sliding tube 27 more and more through the push rod 19. When the sum of the elastic force of the spring B 23 and the pressure of the float plate 16 on the sliding tube 27 is greater than the friction force of the spring pin 28 on the lower top hole 29, the spring pin 28 is pressed back, and the sliding tube 27 quickly returns to its initial position. The inner circulation pipe 4 returns to its normal working state, the spring pin 28 hits the upper top hole, and the spring B 23 returns to its initial state. The trigger switch 21 is released, the water pump 2 stops working, and the liquid level in the gas-liquid separation tank will gradually descend in the normal working state. The float plate 16 finally returns to the position of the stopper 17, and the gas-liquid separation tank returns to its original working state and continues to work.

[0078] When the internal circulation pipe of the IC reactor becomes clogged, the float rises, automatically triggering the clearing device to clear the blockage. Once the blockage is cleared, the float descends, returning to normal. This invention eliminates the need for manual clearing and is automatically triggered, reducing the maintenance difficulty of the IC reactor and improving its efficiency.

[0079] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.

The IC reactor clearing method according to claim 7, wherein: The following steps are involved: S1: When the inner circulation pipe is blocked, the liquid level in the liquid-gas separation tank slowly rises, lifting the float plate, which floats upward along the guide plate, driving spring A. Spring A slowly tightens the connecting rope, and the elastic force acts on the sliding pipe through the tightened connecting rope. When the elastic force is greater than the friction force of the spring pin on the sliding pipe, the spring pin is pressed back into the mounting hole at the bottom of the liquid-gas separation tank. Under the action of the elastic force accumulated by spring A, the sliding pipe slides upward quickly until it hits the step where the touch switch is located, closing the openings on both sides of the inner circulation pipe. After the sliding pipe moves, spring B moves from the initial state to the stretched position, and the spring pin just gets stuck in the lower top hole. The elastic force of spring B is less than the friction force of the spring pin on the lower top hole, and the sliding pipe is locked at this time. S2: After the touch switch is pressed, the clearing device starts to operate, the water pump starts, and pressurized water is delivered to the inner circulation pipe behind the sliding pipe seal; S3: Under the action of pressurized water, the blocked part of the internal circulation pipe is loosened and flushed back to the bottom of the IC reactor by the pressurized water; S4: After the inner circulation pipe is unblocked, the water pump sucks water and discharges water. The liquid level in the liquid-gas separation tank drives the float plate to gradually drop, and the push rod slowly supports the sliding pipe. At this time, the liquid level continues to drop, and the buoyancy of the float plate gradually decreases. More and more of its own gravity acts on the sliding pipe through the push rod. When the sum of the elastic force of spring B and the pressure of the float plate on the sliding pipe is greater than the friction force of the spring pin on the lower top hole, the spring pin is pressed back, and the sliding pipe quickly returns to its initial position. The inner circulation pipe returns to normal working state, the spring pin hits the upper top hole, and spring B returns to its initial state. The trigger switch is released, the water pump stops working, and the liquid level in the liquid-gas separation tank will gradually drop in normal working state. The float plate eventually returns to the stop position, and the liquid-gas separation tank returns to its original working state and continues to work.
