Description

Technical Field

[0001] This utility model relates to the field of purification tank technology, and in particular to a purification tank. Background Technology

[0002] A purification tank is a device used to process liquids or gases. Its core function is to remove contaminants through physical, chemical, or biological methods to meet water or gas purification standards.

[0003] In the fields of natural gas desulfurization and refinery gas treatment, the efficient purification of amine-rich liquids is crucial. The light hydrocarbons, solid particles, and degradation products carried in these liquids can easily cause system foaming, equipment corrosion, and solvent degradation, severely limiting the operating efficiency and economy of the equipment. Existing technologies mostly employ simple purification tank sedimentation separation or direct filtration, which suffers from problems such as incomplete separation of light hydrocarbons, heavy filtration load, poor coordination between units, and high energy consumption.

[0004] Therefore, we have proposed a purification tank. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a purification tank.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a purification tank, including a regeneration tower body, a filter box is provided on one side of the regeneration tower body, and a pumping component is fixedly connected between the filter box and the regeneration tower body.

[0007] A filter assembly is sealed and inserted into one side of the filter housing, and the filter assembly and the filter housing are fixedly connected by a quick-release assembly.

[0008] A pneumatic slide valve is fixedly connected to the top of the filter box. A conical tube is fixedly connected to the top of the pneumatic slide valve. A thick pipe is fixedly connected to the top of the conical tube. An exhaust pipe that penetrates to the inside of the conical tube is fixedly connected to the top of the thick pipe.

[0009] A pipe heater is fixedly connected to one side of the outer surface of the thick pipe along the tangential direction.

[0010] Furthermore, support frames are fixedly connected to both sides of the outer surface of the filter housing. The support frames can raise the height of the filter housing, which is beneficial for the arrangement of the pumping components.

[0011] Furthermore, the pumping assembly includes a pump body, which is fixedly installed at the bottom of the filter box. The input end of the pump body is fixedly connected to the filter box, and the output end of the pump body is fixedly connected to a long pipe, which is fixedly connected to the main body of the regeneration tower. The pump body can transport the amine liquid at the bottom of the filter box to the main body of the regeneration tower 1.

[0012] Furthermore, the filter assembly includes a frame, and the frame is sealed and plugged into the filter housing. A filter element is fixedly connected to the inner surface of the frame, and the frame arrangement facilitates the installation of the filter element.

[0013] Furthermore, the quick-release assembly includes a fixing frame, which is fixedly installed on one outer wall of the filter box and fits against the bottom of the frame. A handwheel is provided on one side of the filter box, and a screw is fixedly connected to the handwheel on one side of the fixing frame. The screw passes through the fixing frame and is rotatably connected to the fixing frame. The handwheel facilitates manual driving of the screw to rotate.

[0014] Furthermore, a pressure plate is threaded onto the outer surface of the screw, and the pressure plate is slidably connected to the fixing frame. The fixing frame has a limiting effect on the pressure plate, which can ensure the stability of the pressure plate's movement.

[0015] Furthermore, a wire mesh demister is fixedly connected to the inlet of the exhaust pipe to remove amine droplets from the gas.

[0016] The beneficial effects of this utility model are:

[0017] This invention integrates heating and desorption, centrifugal separation, and precision filtration. It efficiently separates light hydrocarbons through tangential heating and conical centrifugation, and combines quick-release filter elements and pneumatic valves to enable maintenance without stopping the machine. This significantly improves the purification efficiency and operational safety of amine solution and ensures the stable operation of downstream equipment. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-3 As shown, a purification tank is disclosed, including a regeneration tower body 1. A filter box 7 is provided on one side of the regeneration tower body 1. Support frames 12 are fixedly connected to both sides of the outer surface of the filter box 7. The support frames 12 are used to raise the height of the filter box 7 to facilitate the installation of the pumping components. Before actual use, a pressure relief valve should be installed on the top of the filter box 7 to avoid excessive internal pressure.

[0026] A pumping assembly is fixedly connected between the filter housing 7 and the regeneration tower body 1. The pumping assembly includes a pump body 11, which is fixedly installed at the bottom of the filter housing 7. The input end of the pump body 11 is fixedly connected to the filter housing 7, and the output end of the pump body 11 is fixedly connected to a long pipe 8, which is fixedly connected to the regeneration tower body 1. A control valve is fixedly connected at the connection between the long pipe 8 and the pump body 11 to control the opening and closing of the pump body 11 and the long pipe 8.

[0027] A filter assembly is sealed and inserted into one side of the filter housing 7. The filter assembly includes a frame 14, and the frame 14 is sealed and inserted into the filter housing 7. A filter element 13 is fixedly connected to the inner surface of the frame 14, and a sealing gasket is covered on the outer surface of the frame 14 to ensure the airtightness between the frame 14 and the filter housing 7.

[0028] The filter assembly and the filter housing 7 are connected by a quick-release assembly, which includes a fixing frame 6. The fixing frame 6 is fixedly installed on one side of the outer wall of the filter housing 7 and fits against the bottom of the frame 14. A handwheel 16 is provided on one side of the filter housing 7. A screw 15 is fixedly connected to the handwheel 16 on one side of the fixing frame 6. The screw 15 passes through the fixing frame 6 and is rotatably connected to the fixing frame 6. A pressure plate 10 is threaded onto the outer surface of the screw 15 and is slidably connected to the fixing frame 6. The thread helix angle of the screw 15 is smaller than the friction angle, so that the screw 15 has a self-locking ability and can prevent it from shifting due to vibration or load.

[0029] A pneumatic slide gate valve 5 is fixedly connected to the top of the filter housing 7. A cone tube 9 is fixedly connected to the top of the pneumatic slide gate valve 5. A thick pipe 3 is fixedly connected to the top of the cone tube 9. An exhaust pipe 2 that penetrates to the inside of the cone tube 9 is fixedly connected to the top of the thick pipe 3. A wire mesh demister 17 is fixedly connected to the inlet of the exhaust pipe 2. The wire mesh demister 17 is a gas-liquid separation device. Gas passes through the wire pad of the demister and can remove the entrained mist.

[0030] A pipe heater 4 is fixedly connected to one side of the outer surface of the thick pipe 3 along the tangential direction. The pipe heater 4 is an electric heating device used to heat the pipe or the medium inside it. It is mainly composed of multiple tubular electric heating elements, a cylinder, a guide plate, etc.

[0031] Working principle: The rich amine solution (loaded with acidic gases and impurities) from the upstream system first passes through a pre-filter (not shown in the figure, located on the inlet pipe of this unit) to remove larger solid particles, providing protection for the core components of this unit. Subsequently, the amine solution enters this purification unit under system pressure.

[0032] After entering the device, the amine solution flows through the pipe heater 4. This heater uses electric heating as the heat source to heat the amine solution in contact. As the temperature of the amine solution rises, the dissolved light hydrocarbons, due to their decreasing solubility with increasing temperature, will precipitate out of the amine solution, forming tiny bubbles, and begin to separate from the amine solution.

[0033] The amine liquid mixture carrying precipitated bubbles enters the separation chamber formed by the coarse tube 3 and the conical tube 9 tangentially. The tangential inlet design causes the fluid to rotate at high speed within the chamber, generating a strong centrifugal force. Under the action of centrifugal force, the denser amine liquid is thrown towards the chamber wall and flows downward along the wall; while the less dense gas phase (hydrocarbons) gathers towards the center and escapes upward.

[0034] The upward-escaped gas passes through the wire mesh demister 17 at the inlet of exhaust pipe 2, where the entrained amine droplets are captured, gathered, and fall back, thus ensuring zero amine loss. The separated pure hydrocarbon gas is discharged from the top of exhaust pipe 2 and sent to the flare or recovery system.

[0035] After centrifugation, the amine solution flows downward into the filter chamber 7 and permeates the filter element 13. The filter element 13 completely intercepts and adsorbs any remaining trace solid particles, degradation products, and liquid hydrocarbons, achieving deep purification. The purified amine solution accumulates at the bottom of the filter chamber 7.

[0036] The clean amine liquid accumulated at the bottom of the filter box 7 is powered by the pump body 11 and is stably pumped through the long pipe 8 to the main body of the regeneration tower 1 for subsequent deep regeneration treatment.

[0037] When the filter element needs to be replaced, the safety procedure must be followed: First, close the outlet valve, open the pressure relief valve to confirm that the internal pressure of the filter housing 7 has dropped to normal pressure, and then close the pneumatic slide valve 5 to achieve double isolation from the upper cavity. After that, the handwheel 16 can be rotated to release the pressure plate 10, and the frame 14 along with the filter element 13 can be safely pulled out from the side for replacement.

[0038] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
