Description

Technical Field

[0001] This invention relates to the field of gas-liquid separation technology, specifically a vertical blade gas-liquid separator. Background Technology

[0002] Chinese invention patent CN110227299B discloses a blade-type gas-liquid separator, comprising a separation tank with an air inlet and outlet at the top, a drain outlet at the bottom, and an internal separation mechanism and outlet pipe. The separation mechanism includes coaxially arranged swirl blades and a slit pipe. One end of the outlet pipe connects to the air inlet, and the other end connects to the slit pipe. The outlet pipe and the slit pipe are interconnected to form a whole that passes through the axis of the swirl blades. The top of the slit on the slit pipe does not exceed the upper surface of the swirl blades. This invention, through structural design of the separation mechanism, combines three separation principles and optimizes the separation sequence, effectively avoiding droplet splashing and secondary entrainment, thereby improving separation efficiency and significantly reducing the space occupied by the gas-liquid separator. The swirl blades of this invention require very few blades, resulting in a short gas-liquid mixing flow path and a small airflow bending angle, greatly reducing airflow pressure loss.

[0003] However, during the use of this invention, when processing gas-liquid mixtures containing viscous, easily crystallizing, or solid particles, the surfaces of core separation elements such as baffles, blades, or wire mesh are prone to adhesion, scaling, or even blockage. This not only rapidly reduces separation efficiency but also often forces the equipment to be shut down for manual or chemical cleaning, seriously affecting the continuity and stability of production. Therefore, a vertical blade gas-liquid separator is proposed to solve the problems mentioned above. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a vertical blade gas-liquid separator, which has the advantages of high-efficiency separation and automatic anti-clogging and cleaning. It solves the problem that existing gas-liquid separators are prone to clogging during use, which not only rapidly reduces separation efficiency but also often forces the equipment to be shut down for manual or chemical cleaning, seriously affecting the continuity and stability of production.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vertical blade gas-liquid separator, comprising a vertical tank and a support base fixedly connected to the bottom of the vertical tank, wherein a baffle separator is fixedly connected inside the vertical tank, and an mounting plate is fixedly connected to the inner wall of the vertical tank, wherein a knocking cleaning mechanism capable of cleaning the baffle separator is provided on the mounting plate, and a cyclone separator is provided inside the vertical tank;

[0006] The knocking cleaning mechanism includes a fixed housing fixedly connected to the mounting plate near the baffle separator. The fixed housing is provided with an elastic movable component. A rotating plate is rotatably connected to the mounting plate near the fixed housing. A connecting rod is rotatably connected to the rotating plate near the fixed housing. A drive motor is fixedly connected to the outer surface of the vertical tank. A drive plate extending to the rotating plate is fixedly connected to the output shaft of the drive motor.

[0007] The cyclone separator includes a support ring fixedly connected to the inner wall of the vertical tank, and the inside of the support ring is respectively provided with a sealing cylinder, a blind plate and blades.

[0008] Furthermore, the elastic movable component includes a striking rod that is slidably connected inside the fixed housing and extends to its bottom. A fixing ring is fixedly connected to one side of the striking rod inside the fixed housing, and a return spring is fixedly connected between the fixing ring and the top wall of the fixed housing.

[0009] Furthermore, a hinge is provided between the striking rod and the connecting rod, and the striking rod and the connecting rod are hinged together by the hinge. A protrusion is fixedly connected to the side of the rotating plate near the driving plate.

[0010] Furthermore, a rubber head is fixedly connected to one end of the striking rod near the baffle separator, and the return spring is sleeved on the outside of the striking rod.

[0011] Furthermore, the sealing cylinder and the support ring are designed as concentric circles, the blind plate is fixedly connected to the lower surface of the sealing cylinder, and the blade is fixedly connected between the sealing cylinder and the support ring.

[0012] Furthermore, there are two cyclone separators, which are respectively located at the top and bottom of the air intake channel on the vertical tank.

[0013] Furthermore, the baffle separator includes multiple vertically arranged corrugated plates, the surface of which is provided with an anti-stick coating, and the corrugated plates form tortuous airflow channels to enhance the gas-liquid separation effect and reduce clogging.

[0014] Furthermore, an exhaust pipe connected to the interior is fixedly connected to the top of the outer surface of the vertical tank, a drain pipe extending into the interior is fixedly connected to the bottom of the vertical tank, and an air inlet pipe is fixedly connected to the side of the vertical tank away from the exhaust pipe.

[0015] Furthermore, a level gauge is installed on the outside of the vertical tank, and two connecting pipes are fixedly connected between the vertical tank and the level gauge. Scale lines are provided on the outer surface of the level gauge.

[0016] Furthermore, a check valve and an electromagnetic drain valve are fixedly connected in sequence on the drain pipe. The electromagnetic drain valve is electrically linked to the level gauge. A stainless steel wire mesh demister is fixedly connected inside the exhaust pipe. The inner wall of the vertical tank is coated with an anti-corrosion and wear-resistant ceramic coating. Several evenly distributed reinforcing ribs are fixedly connected to the outer wall of the vertical tank. The bottom end of the reinforcing ribs is fixedly connected to the support base.

[0017] Compared with the prior art, the present invention provides a vertical blade gas-liquid separator, which has the following advantages:

[0018] 1. This vertical blade gas-liquid separator features a knocking cleaning mechanism that combines a drive motor, rotating plate, connecting rod, and elastic movable components. This mechanism enables automated, periodic knocking of the baffle separator, eliminating the need for manual downtime cleaning and ensuring continuous equipment operation. The rubber head design at the end of the knocking rod ensures a gentle knocking action without hard impact, preventing damage to the baffle separator's corrugated plates. The combination of the return spring and the fixing ring ensures precise elastic reset of the knocking rod, guaranteeing stable and smooth operation of the cleaning mechanism. This effectively shakes off droplets and impurities adhering to the corrugated plate surface, addressing the blockage problem at its source.

[0019] 2. This vertical blade gas-liquid separator, by installing a graduated level gauge on the outside of the vertical tank, and sequentially installing a check valve and an electromagnetic drain valve electrically linked to the level gauge on the drain pipe, can monitor the liquid level in the tank in real time and realize automatic draining. When the liquid level reaches the set threshold, the drain valve automatically opens and automatically closes when the liquid level drops to a safe value. This effectively avoids the problem of liquid droplets being entrained in the gas phase due to excessive liquid accumulation, and also prevents component wear caused by frequent opening and closing of the drain valve. The check valve completely eliminates the phenomenon of gas phase escaping from the drain pipe, ensuring the stability of the draining process.

[0020] 3. This vertical blade gas-liquid separator, by setting up a baffle separator inside the vertical tank and a set of cyclone separators at the top and bottom of the air inlet channel, forms a multi-stage composite separation system. It achieves initial inertial separation of large-diameter droplets through the tortuous airflow channel of the baffle separator, and uses the dual cyclone separators to perform secondary centrifugal separation of medium and small-diameter droplets. It is suitable for the separation needs of droplets of different sizes. Compared with existing single-stage cyclone separators, the separation efficiency is significantly improved. It solves the problem that existing gas-liquid separators are prone to clogging during use, which not only rapidly reduces the separation efficiency, but also often forces the equipment to be shut down for manual cleaning or chemical cleaning, seriously affecting the continuity and stability of production.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 3 This embodiment of a vertical blade gas-liquid separator includes a vertical tank 1 and a support base 2 fixedly connected to the bottom of the vertical tank 1. A baffle separator 3 is fixedly connected inside the vertical tank 1. An installation plate 4 is fixedly connected to the inner wall of the vertical tank 1. The installation plate 4 is provided with a knocking cleaning mechanism that can clean the baffle separator 3. The knocking cleaning mechanism includes a fixed housing 5 fixedly connected to the side of the installation plate 4 near the baffle separator 3. An elastic movable component is provided inside the fixed housing 5. A rotating plate 11 is rotatably connected to the side of the installation plate 4 near the fixed housing 5. A connecting rod 9 is rotatably connected to the side of the rotating plate 11 near the fixed housing 5. A drive motor 14 is fixedly connected to the outer surface of the vertical tank 1. A drive plate 12 extending to one side of the rotating plate 11 is fixedly connected to the output shaft of the drive motor 14.

[0030] Specifically, the elastic movable component includes a striking rod 6 that is slidably connected inside the fixed housing 5 and extends to its bottom. A fixing ring 7 is fixedly connected to one side of the striking rod 6 inside the fixed housing 5. A return spring 8 is fixedly connected between the fixing ring 7 and the inner top wall of the fixed housing 5. A hinge 10 is provided between the striking rod 6 and the connecting rod 9. The striking rod 6 and the connecting rod 9 are hinged together by the hinge 10. A protrusion 13 is fixedly connected to the side of the rotating plate 11 near the drive plate 12.

[0031] It should be noted that a rubber head is fixedly connected to one end of the striking rod 6 near the baffle separator 3, and the return spring 8 is sleeved on the outside of the striking rod 6. When the drive motor 14 drives the drive plate 12 to rotate, it can move the protrusion 13, thereby causing the protrusion 13 to drive the rotating plate 11 to rotate, and then drive the connecting rod 9 to rotate. At this time, due to the action of the hinge 10 and the elastic movable component, the striking rod 6 can move up and down. Each time the drive plate 12 moves the protrusion 13 once, the striking rod 6 can complete one strike on the baffle separator 3.

[0032] It should be noted that the speed of the drive motor 14 can be adjusted by an external frequency converter to achieve flexible control of the tapping frequency. Whenever the drive plate 12 moves the protrusion 13 once, the tapping rod 6 will extend downward and perform an elastic tap on the baffle separator 3, effectively shaking off the droplets and impurities adhering to the surface of the waveform plate.

[0033] Please see Figure 1 and Figure 4 In this embodiment, a cyclone separator 15 is provided inside the vertical tank 1. The cyclone separator 15 includes a support ring 151 fixedly connected to the inner wall of the vertical tank 1. The support ring 151 is provided with a sealing cylinder 152, a blind plate 153 and a blade 154. The sealing cylinder 152 and the support ring 151 are designed as concentric circles. The blind plate 153 is fixedly connected to the lower surface of the sealing cylinder 152, and the blade 154 is fixedly connected between the sealing cylinder 152 and the support ring 151.

[0034] Specifically, there are two cyclone separators 15, which are respectively distributed at the top and bottom of the air inlet channel on the vertical tank 1. The baffle separator 3 includes multiple vertically arranged corrugated plates with an anti-stick coating on the surface of the corrugated plates. The corrugated plates form a tortuous airflow channel to enhance the gas-liquid separation effect and reduce clogging.

[0035] It should be noted that the two cyclone separators 15 are symmetrically distributed on both sides of the air inlet channel, which allows the gas-liquid mixture entering the vertical tank 1 to be simultaneously subjected to the effects of the upper and lower cyclone fields, avoiding the phenomenon of airflow deviation or eddy current, and greatly improving the uniformity of centrifugal separation. The blind plate 153 can block the flow of gas phase into the sealed cylinder 152, forcing the gas-liquid mixture to form a cyclone along the channel between the blades 154, while the anti-stick coating can prevent droplets from solidifying and scaling on the surface of the corrugated plate, further extending the continuous operation time of the equipment.

[0036] Please see Figure 1 and Figure 5 In this embodiment, an exhaust pipe 16 is fixedly connected to the top of the outer surface of the vertical tank 1 and communicates with its interior. A drain pipe 17 extending into its interior is fixedly connected to the bottom of the vertical tank 1. An air inlet pipe 18 is fixedly connected to the side of the vertical tank 1 away from the exhaust pipe 16.

[0037] Specifically, the air inlet pipe 18 is tangentially arranged along the side wall of the vertical tank 1, so that the gas-liquid mixture enters the tank in a tangential manner, which can pre-form a preliminary vortex and lay the foundation for subsequent separation.

[0038] It should be noted that the inlet of the air inlet pipe 18 is also equipped with a flange connection structure to facilitate connection with external process pipes. The outer walls of the exhaust pipe 16 and the liquid drain pipe 17 are both wrapped with a heat insulation layer, which can be adapted to low temperature or high temperature conditions to prevent the medium from condensing or vaporizing in the pipe and affecting the separation effect.

[0039] Please see Figure 1 and Figure 6 In this embodiment, a level gauge 19 is provided on the outside of the vertical tank 1. Two connecting pipes 20 are fixedly connected between the vertical tank 1 and the level gauge 19. A scale line 21 is provided on the outer surface of the level gauge 19.

[0040] Specifically, a check valve and an electromagnetic drain valve are fixedly connected in sequence on the drain pipe 17. The electromagnetic drain valve is electrically linked to the level gauge 19. A stainless steel wire mesh demister is fixedly connected inside the exhaust pipe 16. The inner wall of the vertical tank 1 is coated with an anti-corrosion and wear-resistant ceramic coating. Several evenly distributed reinforcing ribs are fixedly connected to the outer wall of the vertical tank 1. The bottom end of the reinforcing ribs is fixedly connected to the support base 2.

[0041] It should be noted that the level gauge 19 is a magnetic float level gauge, and its internal magnetic float is electrically connected to the controller of the electromagnetic drain valve. When the liquid level reaches the preset high liquid level threshold, the controller automatically triggers the electromagnetic drain valve to open and drain the liquid. When the liquid level drops to the preset low liquid level threshold, the electromagnetic drain valve automatically closes. The check valve can effectively prevent the liquid phase in the drain pipe 17 from flowing back, and at the same time prevent the gas phase in the tank from escaping from the drain pipe 17.

[0042] The working principle of the above embodiments is as follows:

[0043] First, the gas-liquid separator is fixedly installed at the designated work position using the support base 2. The inlet pipe 18 is connected to the external gas-liquid mixing process pipeline via a flange, the exhaust pipe 16 is connected to the gas phase collection pipeline, and the liquid discharge pipe 17 is connected to the liquid phase recovery pipeline. After the equipment is started, the gas-liquid mixed medium enters the vertical tank 1 tangentially through the inlet pipe 18, forming a preliminary swirling flow inside the tank. Large-diameter droplets first impact the inner wall of the tank and settle under inertia. Subsequently, the gas-liquid mixture flows upward through the swirling separator 15 at the bottom of the inlet channel, forming a strong swirling flow under the guidance of the blades 154. Medium-diameter droplets are thrown towards the inner side of the support ring 151 under centrifugal force and settle along the wall. The preliminarily purified gas phase continues to flow upward through the baffle separator 3. In the tortuous airflow channel, the residual droplets collide and adhere with the corrugated plate, achieving secondary inertial separation. Simultaneously, the drive motor 14 drives the knocking cleaning mechanism to work continuously, periodically knocking the corrugated plate of the baffle separator 3 to shake off the adhering droplets and impurities, preventing channel blockage. The gas phase after baffle separation flows through the cyclone separator 15 at the top of the air inlet channel to complete the third centrifugal separation, removing small and medium-sized droplets. Finally, the gas phase flows upward through the stainless steel wire mesh demister inside the exhaust pipe 16 to capture residual micron-sized droplets, and the purified gas phase is discharged from the exhaust pipe 16. All the separated liquid phases are collected at the bottom of the vertical tank 1. The level gauge 19 monitors the liquid level in the tank in real time. When the liquid level reaches the high threshold, the electromagnetic drain valve automatically opens, and the liquid phase is discharged through the drain pipe 17. The check valve prevents the gas phase from escaping. When the liquid level drops to the low threshold, the electromagnetic drain valve closes, completing one drain cycle. This continuous operation achieves efficient and continuous separation of the gas-liquid mixture.

[0044] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
