Description

Technical Field

[0001] This utility model relates to the technical field of wind power conveying equipment, specifically a catalyst cyclone separator. Background Technology

[0002] A phenylamine fluidized bed reactor is a type of fluidized bed reactor that uses ammonia and phenol as raw materials to react and produce phenylamine under the action of a fixed catalyst. The catalyst used in the aniline fluidized bed reactor and the three-stage cyclone separator have relatively weak ability to capture small particles.

[0003] The fluidized bed reactor for butadiene production via butene oxidative dehydrogenation, disclosed in reference CN202416538U, features a three-stage cyclone separator assembly outside the reactor body. The gas outlet of the first-stage cyclone separator assembly is connected to the inlet of the second-stage cyclone separator assembly, and the gas outlet of the second-stage cyclone separator assembly is connected to the inlet of the third-stage cyclone separator assembly via pipelines. The feed leg of the third-stage cyclone separator assembly is connected to a spent catalyst storage tank. The cyclone separator assembly is located outside the reactor body, resulting in a relatively large equipment footprint. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a catalyst cyclone separator that enhances the ability to capture small particles and reduces the equipment footprint.

[0005] To solve the above technical problems, this utility model provides a catalyst cyclone separator, including a primary cyclone separator group, a secondary cyclone separator group, and a tertiary cyclone separator group inside a reactor cylinder. The primary, secondary, and tertiary cyclone separator groups are respectively fixedly suspended on the top surface of the reactor cylinder by cyclone hangers at their respective tops. The inlet and outlet of the primary cyclone separator group are respectively provided with an inlet square tube 1 and an outlet round tube 1; the inlet and outlet of the secondary cyclone separator group are respectively provided with an inlet square tube 2 and an outlet round tube 2; and the inlet and outlet of the tertiary cyclone separator group are respectively provided with an inlet square tube 3 and an outlet round tube 3. The size of the inlet square tube 1 is larger than that of the inlet square tube 2, and the size of the inlet square tube 2 is the same as that of the inlet square tube 3. The diameters of the outlet round tubes 1, 2, and 3 decrease sequentially.

[0006] By adopting the above technical solution, the three-stage cyclone separator assembly is directly integrated into the reactor shell, eliminating the need for external piping connections and independent support structures, significantly reducing the equipment's footprint and installation space. The first-stage inlet square tube has the largest size, initially separating large catalyst particles; the second and third-stage inlet square tubes are the same size but smaller, targeting fine particles for deeper separation, achieving staged treatment. The diameter of the outlet circular tube decreases sequentially to control the gas flow rate and gradually increase the centrifugal force, enhancing the capture ability of small particles and improving the overall separation efficiency.

[0007] Preferably, a gas collection chamber is provided at the top of the reactor shell, and an exhaust port is provided at the top of the gas collection chamber; the outlet circular pipe of the three-stage cyclone separator group is connected to the gas collection chamber.

[0008] By adopting the above technical solution, the gas collection chamber buffers fluctuations in gas flow and catalyst load, ensuring that the cyclone separator can still operate stably under varying operating conditions.

[0009] Preferably, the primary cyclone material leg of the primary cyclone separator group is fixedly connected to the inner wall of the reactor cylinder through a cyclone material leg tube support.

[0010] By adopting the above technical solution, under the influence of high-speed gas flow and catalyst particle impact, the primary cyclone material leg will oscillate or displace due to vibration. The primary cyclone material leg support is rigidly connected to the inner wall of the reactor cylinder, effectively suppressing mechanical vibration and avoiding equipment fatigue or loosening of connecting parts caused by shaking.

[0011] Preferably, the primary cyclone material legs of the primary cyclone separator group, the secondary cyclone material legs of the secondary cyclone separator group, and the tertiary cyclone material legs of the tertiary cyclone separator group are fixedly connected by tie rods.

[0012] By adopting the above technical solution, the two cyclone material legs are connected by tie rods to fix each level of material leg into one, thereby preventing material leg vibration and enhancing structural stability.

[0013] Preferably, the bottom of the secondary cyclone material leg of the secondary cyclone separator group is provided with a secondary cyclone material leg purge pipe.

[0014] By adopting the above technical solution, the secondary cyclone purging pipe continuously or intermittently injects high-pressure gas, such as nitrogen, into the secondary cyclone purging leg, using the airflow impact to break the adhesion between catalyst particles, thus preventing powder from accumulating and clogging at the bottom of the secondary cyclone purging leg.

[0015] Preferably, the bottom of the three-stage cyclone separator assembly is equipped with a three-stage cyclone material leg purge pipe.

[0016] By adopting the above technical solution, the three-cyclone material leg purging pipe continuously or intermittently injects high-pressure gas, such as nitrogen, into the three-stage cyclone material leg, using the airflow impact to break the adhesion between catalyst particles, thus preventing powder from accumulating at the bottom of the three-stage cyclone material leg and forming a blockage.

[0017] Preferably, a two-rotor valve purge pipe is installed at the inlet of the wing valve at the bottom end of the secondary cyclone material leg.

[0018] By adopting the above technical solution, the two-rotor valve purge pipe continuously or intermittently injects high-pressure gas, such as nitrogen, into the inlet of the rotor valve. The airflow impact breaks the adhesion between catalyst particles, thus preventing powder from accumulating and clogging at the rotor valve at the bottom of the secondary cyclone material leg.

[0019] Preferably, a three-rotor valve purge pipe is installed at the inlet of the wing valve at the bottom end of the three-stage cyclone material leg.

[0020] By adopting the above technical solution, the three-rotor valve purge pipe continuously or intermittently injects high-pressure gas, such as nitrogen, into the inlet of the rotor valve. The airflow impact breaks the adhesion between catalyst particles, thus preventing powder from accumulating and clogging at the rotor valve at the bottom of the three-stage cyclone material leg.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. The primary inlet square tube of this invention has the largest size, which is used for the initial separation of large catalyst particles; the secondary and tertiary inlet square tubes are the same size but smaller, which are used for the deep separation of fine particles, thus achieving graded treatment. The diameter of the outlet circular tube decreases sequentially to control the gas flow rate and gradually increase the centrifugal force, thereby enhancing the ability to capture small particles and improving the overall separation efficiency.

[0023] 2. This utility model directly integrates the three-stage cyclone separator group into the reactor shell, eliminating the need for external pipeline connections and independent support structures, and significantly reducing the equipment footprint and installation space.

[0024] 3. In this utility model, the two cyclone material legs are connected by tie rods to fix each level of material leg into one piece, thereby preventing material leg vibration and enhancing structural stability. Attached Figure Description

[0030] like Figure 1 As shown, the catalyst cyclone separator includes a primary cyclone separator group 1, a secondary cyclone separator group 8, and a tertiary cyclone separator group 9 within the reactor cylinder 2. The primary cyclone separator group 1, the secondary cyclone separator group 8, and the tertiary cyclone separator group 9 are respectively fixedly suspended on the top surface of the reactor cylinder 2 via cyclone hangers 5 at their respective tops. Figure 2 As shown, the inlet and outlet of the first-stage cyclone separator group 1 are respectively equipped with an inlet square tube 3 and an outlet round tube 4; the inlet and outlet of the second-stage cyclone separator group 8 are respectively equipped with an inlet square tube 21 and an outlet round tube 22; and the inlet and outlet of the third-stage cyclone separator group 9 are respectively equipped with an inlet square tube 23 and an outlet round tube 7. The outlet round tube 7 is located at the top of the third-stage cyclone separator group 9. The size of the inlet square tube 3 is larger than that of the inlet square tube 21, and the size of the inlet square tube 21 is the same as that of the inlet square tube 23; the diameters of the outlet round tubes 4, 22, and 7 decrease sequentially. The outlet round tube 4 is provided with a connecting part, which is inserted into the outlet round tube 1 mounting port on the inlet square tube 21. Similarly, the outlet round tube 22 is provided with a connecting part, which is inserted into the outlet round tube 2 mounting port on the inlet square tube 23. This application integrates the three-stage cyclone separator assembly directly into the reactor shell 2, eliminating the need for external piping connections and independent support structures, significantly reducing the equipment's footprint and installation space. The first-stage inlet square tube has the largest size, initially separating large catalyst particles; the second and third-stage inlet square tubes are the same size but smaller, targeting fine particles for deeper separation, achieving staged treatment. The outlet circular tube diameter decreases sequentially to control the gas flow rate and progressively increase centrifugal force, enhancing the capture ability of small particles and improving overall separation efficiency.

[0031] A gas collecting chamber 6 is installed at the top of the reactor shell 2, and an exhaust port 24 is installed at the top of the gas collecting chamber 6; the outlet circular pipe 7 of the three-stage cyclone separator group 9 is connected to the gas collecting chamber 6. The gas collecting chamber 6 buffers fluctuations in gas flow and catalyst load, ensuring that the cyclone separator can still operate stably under varying operating conditions.

[0032] The primary cyclone feed leg 10 of the primary cyclone separator group 1 is fixedly connected to the inner wall of the reactor body 2 via a cyclone feed leg tube support 19. Under the influence of high-speed gas flow and catalyst particle impact, the primary cyclone feed leg 10 will sway or shift due to vibration. The cyclone feed leg tube support 19 rigidly connects the primary cyclone feed leg 10 to the inner wall of the reactor body 2, effectively suppressing mechanical vibration and avoiding equipment fatigue or loosening of connections caused by shaking.

[0033] like Figure 3As shown, the primary cyclone material legs 10 of the primary cyclone separator group 1, the secondary cyclone material legs 13 of the secondary cyclone separator group 8, and the tertiary cyclone material legs 12 of the tertiary cyclone separator group 9 are fixedly connected by tie rods 11. The tie rods 11 pull the material legs together in pairs, fixing each stage of material legs into a single unit, preventing material leg vibration and enhancing structural stability. The outermost cyclone material legs are fixedly connected to the inner wall of the reactor cylinder 2 via mounting pipes 25.

[0034] like Figure 4 As shown, a secondary cyclone separator assembly 8 has a secondary cyclone material leg 13 with a secondary cyclone material leg purge pipe 15 at its bottom. The secondary cyclone material leg purge pipe 15 continuously or intermittently injects high-pressure gas, such as nitrogen, into the secondary cyclone material leg 13, using the airflow impact to break the adhesion between catalyst particles and prevent powder from accumulating and clogging at the bottom of the secondary cyclone material leg 13.

[0035] The bottom of the three-stage cyclone separator group 9 is provided with a three-stage cyclone material leg 12 and a three-stage cyclone material leg purge pipe 14. The three-stage cyclone material leg purge pipe 14 continuously or intermittently injects high-pressure gas, such as nitrogen, into the three-stage cyclone material leg 12, and uses the airflow impact to break the adhesion between catalyst particles, so as to prevent powder from accumulating at the bottom of the three-stage cyclone material leg 12 and forming a blockage.

[0036] The inlet of the wing valve at the bottom of the secondary cyclone material leg 13 is equipped with a two-rotor valve purge pipe 17. The two-rotor valve purge pipe 17 continuously or intermittently injects high-pressure gas, such as nitrogen, into the wing valve inlet, using the airflow impact to break the adhesion between catalyst particles, thus preventing powder from accumulating and clogging at the wing valve at the bottom of the secondary cyclone material leg 13.

[0037] The inlet of the wing valve at the bottom of the three-stage cyclone material leg 12 is equipped with a three-rotor valve purge pipe 16. The three-rotor valve purge pipe 16 continuously or intermittently injects high-pressure gas, such as nitrogen, into the wing valve inlet, using the airflow impact to break the adhesion between catalyst particles, thus preventing powder from accumulating and clogging at the wing valve at the bottom of the three-stage cyclone material leg 12.

[0038] During operation, gas enters through the inlet square tube 3 of the first-stage cyclone separator group 1. The first-stage cyclone separator separates larger catalyst particles, which fall back to the bottom of the reactor body 2 from the first-stage cyclone feed leg 10. An anti-reverse cone is installed at the outlet of the first-stage cyclone feed leg 10. The gas continues to flow from the outlet circular tube 4 of the first-stage cyclone separator group 1 through the inlet square tube 21 to the second-stage cyclone separator group 8. The second-stage cyclone separator separates smaller catalyst particles. After the catalyst accumulates to a certain weight in the second-stage cyclone feed leg 13, the wing valve 18 at the bottom of the second-stage cyclone feed leg 13 opens, and the catalyst particles fall to the bottom of the reactor body 2. The gas then continues from the outlet circular tube 22 through the inlet square tube 3 to the third-stage cyclone separator group 9. The third-stage cyclone separator is the smallest, increasing centrifugal force and further capturing fine particles. The first-stage inlet square tube is the largest, initially separating large catalyst particles; the second and third-stage inlet square tubes are the same size but smaller, performing deeper separation of fine particles, achieving graded treatment. The diameters of the outlet pipes in the first, second, and third stages decrease sequentially to control the gas flow rate and gradually increase the centrifugal force, thereby enhancing the ability to capture small particles and improving the overall separation efficiency.
