Description

Technical Field

[0001] The invention relates to the technical field of gas recovery and purification, and in particular 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 gas, purification liquid and filler; the gas to be purified enters the tower through the air inlet, and during the upward flow of the gas in the tower, it will contact with the purification liquid sprayed from top to bottom; the purification liquid is evenly distributed in the tower through the spray system to form fine droplets, which increases the contact area between the liquid and the gas and purifies the gas.

[0003] In the field of gas recovery and purification, fillers are often used to increase the contact area between gas and purified liquid and improve the removal efficiency of pollutants. The role of the filler 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 filler is a fixed design, and this structure gradually exposes the problem of reduced efficiency during use. With the long-term use of the filler, 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, and the contact effect between the purified liquid and the pollutants decreases, which leads to a significant reduction in the gas purification efficiency.

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

[0040] The hydraulic piston 403 squeezes the return spring 406, and the displacement of the hydraulic piston 403 drives the displacement of the crank push rod 405, and the displacement of the crank push rod 405 drives the ejector rod 407 to move along the stroke crank groove 4026, and the movement of the ejector rod 407 drives the movement of the bottom mesh plate 601, the closed ring 602 and the ejector mesh plate 603, until the hydraulic piston 403 pushes the second hydraulic push ring 4023 into the second hydraulic sleeve ring 4022, and the second hydraulic push ring 4023 squeezes the hydraulic oil in the second hydraulic sleeve ring 4022 into the second hydraulic telescopic rod 4024 through the second hydraulic pipe 4025, and the second hydraulic telescopic rod 402 The elongation 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 connected with the liquid channel 4016, and the return spring 406 drives the liquid piston 403 to return. 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 ring pipe 4010 and the ring outlet pipe 4011. The purified liquid enters the spray ring 508 and the spray head 509 through the ring outlet pipe 4011, and is sprayed onto the filling materials in the bottom mesh plate 601, the closed ring 602 and the top mesh plate 603 through the spray head 509.

[0041] When the liquid piston 403 of the reset curved spring 406 is reset, the first hydraulic push ring 4019 is pushed into the first hydraulic sleeve ring 4018, and 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 opening and closing valve core 4015 to move, and the liquid channel 4016 is switched. At this time, the opening and closing inlet pipe 4012 is connected with the liquid channel 4016. At this time, the opening and closing valve core 4015 is displaced to squeeze 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. The hydraulic oil pushes out the second hydraulic push ring 4023, and the second hydraulic push ring 4023 is reset.

[0042] When the liquid piston 403 is reset, the push rod 405 and the ejector rod 407 are driven to move, and the ejector rod 407 drives the bottom mesh plate 601, the closed ring 602 and the top mesh plate 603 to reset and move, so that the bottom mesh plate 601, the closed ring 602 and the top mesh plate 603 can shake back and forth. When shaking, the filling materials in the bottom mesh plate 601, the closed ring 602 and the top mesh plate 603 are driven to shake, achieving the following effects: Effect 1. The shaking of the packing material can turn over the packing material, which can increase the contact area between the gas and the purification liquid, thereby improving the gas absorption and purification efficiency; the larger the contact surface between the gas and the liquid, the higher the pollutant removal efficiency; Effect 2: When the filler remains stationary for a long time, it will clump or accumulate, thus affecting the uniform flow of the fluid; shaking 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; Effect 3: The shaking of the filler can improve the fluid distribution in the filler, reduce dead zones, i.e., areas where the fluid does not flow smoothly, and ensure that the flow of gas and liquid is more uniform; the filler with good fluidity can promote the passage of gas in the purification tank 2, making the purification effect more uniform and efficient; Effect 4: The flipping filler can help maintain the stability of the liquid film, making the coverage of the liquid film more uniform, thereby improving the efficiency of adsorption and chemical reactions; Effect 5. In the purification process that relies on chemical reactions, the shaking filler can make the contact between the reactants and catalysts in the purification liquid more complete, thereby improving the reaction rate and effect.

[0043] The liquid piston 403 moves back and forth to trigger 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, so as to control 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 with the power ring 401 or the opening and closing outlet pipe 4013 is connected with the power ring 401 for switching.

[0044] When the opening and closing inlet pipe 4012 and the power ring 401 are in an open state, the opening and closing outlet pipe 4013 and the power ring 401 are in a closed state. During this process, the spray head 509 stops spraying, and the spray head 509 sprays intermittently. In order to solve this intermittent spraying condition, solution one is to use the liquid pistons 403 in the three filling tanks 202 with different movable stroke lengths in the power ring 401 to make the spray heads 509 in the three filling tanks 202 staggered in spraying; solution two is to open the solenoid valve 507 on the second branch pipe 506 in the intermittent state, and connect the spray ring 508 and the spray head 509 through the second branch pipe 506, so that the spray head 509 sprays the purification liquid. This device adopts solution two.

[0045] The device can be divided into two working states in the filling tank 202. In working state one, the bottom mesh plate 601, the closed ring 602 and the top mesh plate 603 can be shaken back and forth to make the filling material shake; in working state two, the bottom mesh plate 601, the closed ring 602 and the top mesh plate 603 are fixed.

[0046] The function of the purification liquid is to remove harmful components in the gas by contacting, dissolving or reacting with the pollutants in the gas; the function of the filler is to increase the surface area of ​​gas-liquid contact and promote good contact between the gas and the purification liquid.

[0047] The gas to be purified carries small liquid droplets out of the filling tank 202 and enters the gas-liquid tank 203, where 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 901 through the transfer pipe 8; the gas enters the air permeable mesh pipe 905 through the purification sleeve 901, and the gas is filtered by the activated carbon in the activated carbon box 904, and enters the recovery box 3 from the activated carbon mesh plate 906 and the air permeable port 902. The purified gas is discharged from the recovery gas pipe 909, and the gas is stored through the gas storage device.

[0048] When cleaning the device, first open the electric switch valve 207, discharge the purified liquid in the liquid bottom tank 201 through the drain pipe 206, then pour the cleaning liquid or water through the liquid inlet pipe 204, start the circulation pump 501, and according to the above movement state, the bottom mesh plate 601, the closed ring 602 and the top mesh plate 603 can swing back and forth, and the spray head 509 continuously sprays the cleaning liquid or water to clean the filler.

[0049] After long-term use, pollutants or scale may accumulate on the surface of the packing. By regularly spraying clean water or cleaning fluid and shaking the packing left and right, the accumulation of these pollutants can be effectively prevented, thereby avoiding clogging of the pores of the packing and maintaining its high specific surface area and gas-liquid contact efficiency; shaking the packing and cleaning the surface of the packing help to remove impurities and pollutants attached to the packing and keep it clean. The adsorption capacity and reaction activity of the packing are not affected by the accumulation of pollutants, ensuring that the purification effect is stable and lasting; spraying clean water or cleaning fluid can help dissolve and rinse off the pollutants or impurities adsorbed on the surface of the packing. This cleaning process is similar to the "regeneration" of the packing, which restores its original adsorption capacity or reaction activity, helps to remove accumulated pollutants, and enhances the service life and purification effect of the packing.

[0050] 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 the scope of protection of the present invention.
