Description

Technical Field

[0001] The present invention relates to the technical field of gas recovery and purification, and particularly relates to a gas recovery and purification device for ethoxy pentafluorocyclotriphosphazene production experiments. Background Art

[0002] Existing gas recovery and purification devices achieve gas purification through multiple contacts and interactions between the gas, the purification liquid, and the packing material; the gas to be purified enters the tower body through the air inlet, and during the upward flow of the gas in the tower, it will come into contact with the purification liquid sprayed from top to bottom; the purification liquid is evenly distributed in the tower through the spraying system to form fine liquid droplets, increasing the contact area between the liquid and the gas, and purifying the gas.

[0003] In the field of gas recovery and purification, packing materials are often used to enhance the contact area between the gas and the purification liquid and improve the removal efficiency of pollutants. The role of the packing material is to provide a porous structure for gas flow to increase the surface of gas-liquid contact, thereby improving the adsorption, dissolution, and reaction efficiency of pollutants in the gas. However, in the prior art, the packing material has a fixed design, and this structure gradually exposes the problem of decreased efficiency during use. With the long-term use of the packing material, its surface is easily covered by pollutants, sediments, or scaling substances, resulting in a gradual reduction in the gas-liquid contact area. The gas flow is no longer uniform, the contact effect between the purification liquid and the pollutants decreases, and thus the gas purification efficiency is significantly reduced.

[0004] During the long-term use of the fixed packing material, local gas flow dead zones may also be formed due to uneven gas flow velocity, further exacerbating the decline in purification efficiency. The surface of the fixed packing material is easily blocked or wrapped by certain pollutants, which will affect its original adsorption performance and catalytic effect, making the device unable to maintain a stable purification effect. Therefore, a new technical solution is needed to overcome the deficiencies of the existing fixed structure of the packing material to improve the overall efficiency and long-term stability of the gas purification device.

[0073] In the actual application process of this embodiment, the solenoid valve 507 is used to control the opening of the first branch pipe 505. The purification liquid pushes the displacement of the liquid piston 403 to squeeze the hydraulic oil in the first hydraulic collar 4018 and the first hydraulic push ring 4019 or the second hydraulic collar 4022 and the second hydraulic push ring 4023.

[0076] Specifically, when the spraying head 509 sprays out the purification liquid, tiny liquid droplets will disperse. The flow of the gas will carry the liquid droplets upward, and the small liquid droplets are intercepted by the lower folding plate 702 and the upper folding plate 703.

[0080] In the actual application process of this embodiment: the lower folding plate 702 and the upper folding plate 703 intercept small liquid droplets, avoiding that after the small liquid droplets enter the activated carbon, they may hinder the contact between the gas and the surface of the activated carbon, reducing the gas adsorption efficiency of the activated carbon; the small liquid droplets cover or fill the pores of the activated carbon, reducing the surface area available for gas adsorption of the activated carbon, interfering with the gas adsorption process, reducing the efficiency of the activated carbon or changing the adsorption mechanism.

[0081] Working principle: Start the blower 10.

After the gas to be purified is purified by the purification liquid and the filler three times, it flows through the transfer air pipe 8 to the recovery box 3.

[0082] Start the circulation pump 501. The circulation pump 501 extracts the purified liquid in the liquid bottom tank 201 through the liquid suction pipe 502 and the filter element pipe 503. The purified liquid flows into the liquid supply pipe 504. The solenoid valve 507 on the first branch pipe 505 is opened, and the solenoid valve 507 on the second branch pipe 506 is closed. The purified liquid in the first branch pipe 505 flows into the annular inlet pipe 409 and the liquid inlet annular pipe 408. The purified liquid then flows through the liquid inlet annular pipe 408 into the opening and closing inlet pipe 4012. At this time, the opening and closing valve body 4014 and the opening and closing valve core 4015 are in the open state, and then enters the power ring 401 through the opening and closing inlet pipe 4012. The purified liquid accumulates in the power ring 401 and pushes open the liquid piston 403.

[0083] The liquid piston 403 squeezes the return curved spring 406. The displacement of the liquid piston 403 drives the displacement of the curved push rod 405. The displacement of the curved push rod 405 drives the ejector rod 407 to move along the stroke curved groove 4026. The movement of the ejector rod 407 drives the movement of the bottom mesh plate 601, the sealing ring 602 and the top mesh plate 603 until the liquid piston 403 pushes the second hydraulic push ring 4023 into the second hydraulic sleeve ring 4022. The second hydraulic push ring 4023 squeezes the hydraulic oil in the second hydraulic sleeve ring 4022 and enters the second hydraulic telescopic rod 4024 through the second hydraulic pipe 4025. The elongation of the second hydraulic telescopic rod 4024 drives the opening and closing valve core 4015 to switch the position of the liquid channel 4016 in the opening and closing valve body 4014. At this time, the opening and closing outlet pipe 4013 is communicated with the liquid channel 4016. The return curved spring 406 drives the liquid piston 403 to reset. The liquid piston 403 squeezes the purified liquid in the power ring 401, and the purified liquid flows into the opening and closing outlet pipe 4013, the liquid outlet annular pipe 4010 and the annular outlet pipe 4011. The purified liquid enters the spraying ring 508 and the spray head 509 through the annular outlet pipe 4011, and the purified liquid is sprayed onto the filling material in the bottom mesh plate 601, the sealing ring 602 and the top mesh plate 603 through the spray head 509.

[0084] When the liquid piston 403 of the return curved spring 406 resets, it pushes the first hydraulic push ring 4019 into the first hydraulic sleeve ring 4018. The hydraulic oil in the first hydraulic sleeve ring 4018 enters the first hydraulic telescopic rod 4020 through the first hydraulic pipe 4021. The elongation of the first hydraulic telescopic rod 4020 drives the displacement of the opening and closing valve core 4015 to switch the liquid channel 4016. At this time, the opening and closing inlet pipe 4012 is communicated with the liquid channel 4016. The displacement of the opening and closing valve core 4015 at this time squeezes the retraction of the second hydraulic telescopic rod 4024. The hydraulic oil in the second hydraulic telescopic rod 4024 enters the second hydraulic sleeve ring 4022 through the second hydraulic pipe 4025, and the hydraulic oil pushes out the second hydraulic push ring 4023, and the second hydraulic push ring 4023 resets.

[0085] When the liquid piston 403 resets, it drives the movement of the curved push rod 405 and the ejector rod 407. The ejector rod 407 drives the reset movement of the bottom mesh plate 601, the sealing ring 602 and the top mesh plate 603, so that the bottom mesh plate 601, the sealing ring 602 and the top mesh plate 603 can swing back and forth. When swinging, it drives the filler inside the bottom mesh plate 601, the sealing ring 602 and the top mesh plate 603 to swing, achieving the following effects:

[0086] Effect 1: The swinging of the filler can turn over the filler, which can increase the contact area between the gas and the purification liquid, thereby improving the absorption and purification efficiency of the gas; the larger the surface area of the gas-liquid contact, the higher the removal efficiency of pollutants;

[0087] Effect 2: When the filler remains stationary for a long time, caking or accumulation will occur, which will affect the uniform flow of the fluid; swinging the filler can prevent this phenomenon, ensure the uniform distribution of the filler, and make the gas fully contact with the purification liquid when passing through;

[0088] Effect 3: The swinging of the filler can improve the fluid distribution inside the filler, reduce the dead zone, that is, the area where the fluid flow is not smooth, and ensure that the gas and liquid flow more evenly; the filler with good fluidity can promote the passage of the gas in the purification tank 2, making the purification effect more uniform and efficient;

[0089] Effect 4: The tumbling filler can help maintain the stability of the liquid film, make the coverage of the liquid film more uniform, and thus improve the efficiency of adsorption and chemical reactions;

[0090] Effect 5: For the purification process relying on chemical reactions, the swinging filler can make the contact between the reactants and the catalyst in the purification liquid more sufficient, improving the reaction rate and effect.

[0091] By moving the liquid piston 403 back and forth, it triggers the opening and closing of the first hydraulic collar 4018, the first hydraulic push ring 4019, the first hydraulic telescopic rod 4020 and the first hydraulic pipe 4021 and the second hydraulic collar 4022, the second hydraulic push ring 4023, the second hydraulic telescopic rod 4024 and the second hydraulic pipe 4025, and controls the position switching of the liquid channel 4016 of the opening and closing valve core 4015 in the opening and closing valve body 4014, so that the opening and closing inlet pipe 4012 is connected to the power ring 401 or the opening and closing outlet pipe 4013 is connected to the power ring 401 for switching.

[0092] When the opening and closing inlet pipe 4012 and the power ring 401 are in the open state, the opening and closing outlet pipe 4013 and the power ring 401 are in the closed state. During this process, the spray head 509 stops spraying and there is an intermittent spraying situation for the spray head 509. To solve this intermittent spraying situation; Solution 1 is to use the liquid pistons 403 in the three filling tanks 202 with different moving stroke lengths in the power ring 401 to stagger the spraying of the spray heads 509 in the three filling tanks 202; Solution 2 is to open the solenoid valve 507 on the second branch pipe 506 during the intermittent state, connect the spray ring 508 and the spray head 509 through the second branch pipe 506, and make the spray head 509 spray the purification liquid. This device adopts Solution 2.

[0093] This device in the filling tank 202 can be in two working states. Working state 1: The bottom net plate 601, the closed ring 602 and the top net plate 603 can swing back and forth to make the filling material swing; Working state 2: The bottom net plate 601, the closed ring 602 and the top net plate 603 are fixed.

[0094] The function of the purification liquid is to remove the harmful components in the gas by contacting, dissolving or reacting with the pollutants in the gas; the function of the filling material is to increase the surface area of gas-liquid contact and promote good contact between the gas and the purification liquid.

[0095] The gas to be purified with small liquid droplets exits the filling tank 202 and enters the gas-liquid tank 203. The small liquid droplets are intercepted by the lower folding plate 702 and the upper folding plate 703. At this time, the gas enters the purification sleeve box 901 through the rotating gas pipe 8; the gas enters the breathable network pipe 905 through the purification sleeve box 901, and the gas is filtered by the activated carbon in the activated carbon box 904, enters the recovery box 3 from the activated carbon mesh plate 906 and the breathable port 902, and the purified gas is discharged from the recovery gas pipe 909 and stored by the gas storage device.

[0096] When cleaning this device, first open the electric switch valve 207, discharge the purification liquid in the liquid bottom tank 201 through the drain pipe 206, then pour the cleaning liquid or water through the inlet pipe 204, start the circulation pump 501, and according to the above movement state, make the bottom net plate 601, the closed ring 602 and the top net plate 603 swing back and forth, and the spray head 509 continuously sprays the cleaning liquid or water to clean the filling material.

[0097] After long-term use, contaminants or scale may accumulate on the surface of the packing material. By regularly spraying clean water or cleaning liquid and shaking the packing material from side to side, the accumulation of these contaminants can be effectively prevented, thereby avoiding the blockage of the pores of the packing material and maintaining its high specific surface area and gas-liquid contact efficiency. Shaking the packing material and cleaning the surface of the packing material helps to remove impurities and contaminants attached to the packing material and keep it clean. The adsorption capacity and reaction activity of the packing material are not affected by the accumulation of contaminants, ensuring stable and lasting purification effects. Spraying clean water or cleaning liquid can help dissolve and wash away the contaminants or impurities adsorbed on the surface of the packing material. This cleaning process is similar to the "regeneration" of the packing material, restoring its original adsorption capacity or reaction activity, helping to remove the accumulated contaminants, and enhancing the service life and purification effect of the packing material.

[0098] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
