Abstract
Description
Technical Field
[0001] This invention relates to the field of gas purification technology, and in particular to an industrial gas purification device with automatic baking and dehumidification. Background Technology
[0002] Industrial gases are often used as protective gases, reaction gases, or carrier gases in fields such as electronics, metallurgy, chemicals, semiconductors, and aerospace. Their purity directly determines the quality of the final product and production safety. In steel smelting, water vapor in the gas will reduce product quality. In the manufacturing of high-end lithium batteries, trace amounts of water vapor will cause electrolyte decomposition.
[0003] When using the automatic baking and dehumidification industrial gas purification equipment, first connect the pipeline and power supply, set the baking temperature, dehumidification time, and working pressure. The raw gas first passes through a pre-filter to remove impurities, and then enters the adsorption purification tower. The equipment automatically starts the heating, baking, desorption, regeneration, and cooling dehumidification cycle. The entire process is fully automatic, switching between dual-tower operating states, removing moisture and impurities from the gas online, monitoring parameters in real time, requiring no manual intervention, and continuously outputting high-purity dry industrial gas.
[0004] In existing industrial gas purification equipment, during the baking, regeneration, and cooling processes of the adsorbent bed, the flow rate of the drying or cooling gas is too fast and the residence time is too short when it flows through the adsorbent bed. The gas flow quickly penetrates the bed and is directly discharged, failing to achieve sufficient heat and mass exchange with the adsorbent. Heat and water vapor impurities are not effectively transferred and desorbed, resulting in incomplete baking and regeneration of the adsorbent and uneven cooling. This significantly reduces the regeneration efficiency and cooling rate of the adsorbent, affecting not only the gas purification and dehumidification accuracy and the stability of the outlet gas dew point, but also shortening the service life of the adsorbent and greatly reducing the overall operating efficiency of the equipment.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By combining the airflow rate adjustment module and the turbulence module, the adjustment blades can be rotated to adaptively change the ventilation cross-sectional area on both sides. This expands the ventilation cross-sectional area at the top and reduces the ventilation cross-sectional area at the bottom, creating a throttling and damping effect at the bottom. This restricts the rapid downward flow of gas, forcing the baking hot air or cooling gas to linger and detour inside the adsorbent bed, preventing it from instantly penetrating the bed and escaping. Simultaneously, the internal turbulence module breaks the straight airflow pattern, enhancing the full contact and heat and mass exchange between the gas and the adsorbent. This promotes the complete desorption of water vapor and impurities, greatly reducing incomplete regeneration and uneven cooling. It ensures the accuracy of gas purification and dehumidification and the stability of the gas dew point, while also extending the service life of the adsorbent and improving the operating efficiency of the equipment. 2. By combining the drive module and the filter module, the traditional motor drive is replaced. The structure is simple and the energy consumption is low. It can drive the adsorption bed to rotate, so that the baking adsorption bed is heated evenly and cooled consistently. During the rotation of the adsorption bed, the pusher drives the lifting component to flip and lift the filter plate, forming a gap to guide the flow and avoid the filter plate from sticking together for a long time, which will cause dust accumulation and blockage. 3. By integrating the adsorption tower module, gas delivery module and regeneration module, the raw material gas delivery, purified gas discharge and high-temperature regeneration gas supply are separated into three channels. The two towers are used alternately and the hot air is automatically baked and dehumidified to achieve uninterrupted continuous purification operation and stabilize the gas dew point and purification accuracy.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.
[0020] Example 1: Refer to Figures 1 to 8As shown, an automatic baking and dehumidification industrial gas purification device includes a support frame 1, an adsorption tower module 3 installed inside the support frame 1, a gas conveying module 2 installed on the upper and lower sides of the adsorption tower module 3, and an airflow rate regulating module 4 disposed inside the adsorption tower module 3. The adsorption tower module 3 includes an adsorption tower body 301 fixedly installed on both sides inside the support frame 1. A support cylinder 302 is installed inside the adsorption tower body 301. An adsorption bed 303 is rotatably connected inside the support cylinder 302. A turbulence module 8 is disposed inside the adsorption bed 303. The airflow rate regulating module 4 is disposed on the upper and lower sides of the support cylinder 302. The airflow rate adjustment module 4 includes a flow plate 401 disposed on the upper and lower sides of the support cylinder 302. The surface of the flow plate 401 is provided with air grooves 402 in a ring array. A connector is mounted on the lower surface of the flow plate 401 through a rotating shaft. The side surface of the connector is provided with adjusting blades 403 in a ring array. The adjusting blades 403 rotate and fit against the surface of the flow plate 401. When the adjusting blades 403 on the upper side rotate, their overlapping area with the air grooves 402 increases. When the adjusting blades 403 on the lower side rotate, their overlapping area with the air grooves 402 decreases.
[0021] Specifically, refer to Figure 8 As shown, a torsion spring 404 is provided on the surface of the rotating shaft, and the torsion spring 404 is located inside the flow plate 401. A insertion groove 405 is provided at the bottom of the rotating shaft, and a matching mating part 406 is slidably inserted into the insertion groove 405. A linear motor slider 407 is fixedly installed at one end of the mating part 406. The linear motor slider 407 is electrically slidably connected to an electric magnetic rail 408, and the electric magnetic rail 408 is fixedly installed on the surface of the adsorption bed 303. An L-shaped groove is provided on the top wall of the insertion groove 405. An L-shaped locking rod 409 is slidably connected. A first spring 414 is installed between the insertion groove 405 and the L-shaped locking rod 409. An arc-shaped groove 411 is opened on the surface of the flow plate 401. A limiting block 412 fixedly installed on the surface of the connector is slidably connected inside the arc-shaped groove 411. A column 410 is fixedly installed on the surface of the L-shaped locking rod 409 and slidably connected through the connector and the limiting block 412. A limiting post 413 is slidably connected to the inner top wall of the arc-shaped groove 411. The column 410 overlaps the lower surface of the limiting post 413.
[0022] In this embodiment: the raw gas is diverted into one side of the adsorption tower 301 through the gas delivery module 2. The raw gas moves upward from the bottom of the tower 301, then passes through the regulating blades 403 and the gas groove 402 set below the adsorption bed 303, and then passes through the adsorption bed 303. The adsorbent stored in the adsorption bed 303 adsorbs and purifies the water vapor and impurities in the industrial gas. The purified gas passes through the regulating blades 403 and the gas groove 402 set above. During the purification of the raw gas, the gaps between the regulating blades 403 and the gas groove 402 on both the upper and lower sides are in the same state. At this time, the regulating blades 403 on both the upper and lower sides will not move and will remain in a fixed state. During the purification process, the gas flow rate on both the upper and lower sides is the same. Then the purified gas is diverted and discharged by the gas delivery module 2 at the top. After prolonged purification, the adsorbent stored in the adsorption bed 303 becomes saturated and clogged, requiring a baking, dehumidification, and regeneration process. This baking and dehumidification process involves first baking the adsorbent with baking gas, followed by cooling with cooling gas. During this process, when the cooling or baking gas flows through the gas groove 402 of the flow plate 401, the electric magnetic rail 408 is energized. Upon energization, the linear motor slider 407 slides upwards on the surface of the electric magnetic rail 408. The linear motor slider 407 drives one end of the docking piece 406 to insert into the insertion groove 405. The docking piece 406 then presses the L-shaped retainer 409 into the insertion groove 405. The L-shaped lever 409 drives the column 410 to slide inside the limiting block 412. The column 410 slides until it is flush with the surface of the limiting block 412 and presses the upper limiting post 413 to slide upward. At this time, the docking part 406 and the insertion groove 405 are in a connected state. In the connected state, the electric magnetic rail 408 drives the rotating shaft on the outer surface of the docking part 406 at the top to rotate through the linear motor slider 407. The rotating shaft drives the upper limiting block 412 to slide inside the arc groove 411 to the other end and can no longer slide. At this time, it is necessary to fix the relative position of the air groove 402 and the adjusting blade 403, and de-energize the electric magnetic rail 408. The motor slider 407 moves downward under gravity. At this time, the docking part 406 disengages from the insertion groove 405. Under the restoring force of the first spring 414, the L-shaped locking rod 409 drives the column 410 to return to its original position and slide. At this time, the column 410 is released from the squeezing force on the limiting post 413. The limiting post 413 slides vertically downward inside the arc-shaped groove 411 under gravity and inserts into the limiting block 412. At this time, part of the limiting post 413 is inserted into the hollow interior of the limiting block 412, but the upper part of the limiting post 413 is still within the inner top wall of the arc-shaped groove 411, fixing the position of the adjusting blade 403 and preventing it from moving under the action of airflow. The side regulating blades 403 all rotate on the surface of the flow plate 401 on one side. After the upper regulating blade 403 completes its rotation, its overlap with the air groove 402 is 90%, which maximizes the gas inflow rate. After the lower regulating blade 403 completes its rotation, its overlap with the air groove 402 is 10%, which minimizes the gas inflow rate. This changes the gas flow area of the air groove 402, creating a throttling and damping effect at the lower end. This prevents the gas from being discharged directly downwards quickly, allowing the baking hot air or cooling gas to circulate and linger inside the adsorption bed 303. It prevents the gas from directly penetrating the bed and flowing away, thus avoiding excessive flow rate and prolonging the residence time of the gas in the bed. When the cooling gas is about to complete the cooling of the adsorbent, the adjusting blade 403 needs to be reset. Then, the electric magnetic rail 408 is energized. After energization, the linear motor slider 407 slides upward on the surface of the electric magnetic rail 408. The linear motor slider 407 drives the docking piece 406 at one end to be inserted into the insertion groove 405. At this time, the docking piece 406 presses the L-shaped locking rod 409 to slide upward. The L-shaped locking rod 409 drives the top column 410 to slide in the limiting block 412, pushing the limiting column 413 out of the limiting block 412. Then, with the reset force of the torsion spring 404 and the rotating adsorption bed 303, the adjusting blade 403 is driven to rotate to the initial state. Then, the cooling gas completes the cooling operation of the adsorbent. As the cooling gas or baking gas is continuously input into the adsorption bed 303, it is discharged out through the gas groove 402 below, completing the regeneration operation of the adsorbent. It should be noted that during the purification stage, the regulating blades 403 on both the upper and lower sides remain fixed, and the gas flow rate on both sides is consistent. When the baking, cooling and regeneration operation is performed, the regulating blades 403 on both the upper and lower sides will be adjusted to form a throttling damping effect and improve the regeneration efficiency.
[0023] Example 2: Refer to Figures 4 to 9 As shown, the difference between this embodiment and Embodiment 1 is that a drive module 5 is provided on the outer surface of the adsorption tower body 301. The drive module 5 includes a piston frame 501 fixedly installed on the outer surface of the adsorption tower body 301. A piston plate 502 is slidably connected inside the piston frame 501. A drive toothed plate 503 is provided on one side of the piston plate 502. A reset spring 506 is provided between the drive toothed plate 503 and the piston frame 501. The pressure generated by the gas transport during the regeneration or cooling process of the adsorption tower is converted into the power to make the drive toothed plate 503 slide. There is no need for an external motor to penetrate the tower body, reducing the number of equipment sealing leakage points. The function of the reset spring 506 is to facilitate the reset sliding of the drive toothed plate 503.
[0024] Specifically, refer to Figures 1 to 3 As shown, one side of the Y-shaped output gas pipe 202 is connected to a gas storage tank 6 via a split pipe. The gas storage tank 6 is installed on the surface of the support frame 1. After purification, qualified gas flows into the gas storage tank 6. The purified gas is recycled as the pneumatic drive gas source for the equipment, reducing operating costs. Part of the purified gas is used as a backup gas source for subsequent baking and regeneration, improving the utilization rate of gas resources.
[0025] Specifically, refer to Figures 4 to 9As shown, a driven toothed ring 504 is meshed with one side of the drive toothed plate 503. The driven toothed ring 504 is fixedly installed on the outer surface of the adsorption bed 303. A pressure relief pipe 505 is installed between the adsorption tower body 301 and the piston frame 501. A gas storage tank 6 is installed on the top of the piston frame 501 through a first pipe. A pressure stabilizing valve is provided on the surface of the first pipe. The drive toothed plate 503 meshes with the driven toothed ring 504, causing the adsorption bed 303 to rotate circumferentially. The pressure relief pipe 505 can discharge the gas inside the piston frame 501 to the outside, and regenerate the gas for reuse. The gas storage tank 6 works with the gas pump to provide stable gas supply and continuous power to the drive module 5.
[0026] Specifically, refer to Figures 4 to 9 As shown, filter modules 7 are provided on both the upper and lower sides of the adsorption bed 303. Each filter module 7 includes filter plates 701 tightly attached to the upper and lower sides of the adsorption bed 303. A sliding bushing is provided on the outer surface of the electric magnetic rail 408, and the filter plates 701 are provided on the outer surface of the sliding bushing. Support springs 702 are arranged in a ring array above the filter plates 701. The support springs 702 are fixedly installed on the inner wall of the support cylinder 302. Annular grooves are provided on both the upper and lower sides of the support cylinder 302. Lifting members 703 are rotatably connected in a ring array to the inner wall of each annular groove. A pusher 704 for rotating the adsorption bed 303 is provided on one side. The pusher 704 is fixedly installed on the outer surface of the adsorption bed 303. The inner bottom wall of the annular groove is provided with a recessed groove that matches the lifting member 703. The filter plate 701 is set on the upper and lower sides of the adsorption bed 303. It can perform pre-filtration and impurity removal on the industrial gas entering and leaving the adsorption bed, and intercept solid particles. The rotation of the adsorption bed 303 drives one end of the pusher 704, causing the lifting member 703 to rotate. The lifting filter plate 701 generates a slight vibration, automatically shaking off and trapping impurities, achieving self-cleaning without the need for disassembly and manual cleaning.
[0027] Specifically, refer to Figures 4 to 9As shown, the turbulence module 8 includes several turbulence plates 801 rotatably connected inside the adsorption bed 303. A lever is rotatably connected to the side surface of the adsorption bed 303 on one side of each turbulence plate 801. A rotating gear 802 is provided on the outer surface of the lever. A moving toothed plate 803 is meshed with one side of the rotating gear 802. The moving toothed plate 803 is slidably connected to the outer surface of the adsorption bed 303. A connecting ring is fixedly installed on the top of each moving toothed plate 803 via a connecting column. The connecting ring is rotatably connected to the lower surface of the filter plate 701. When the filter plate 701 vibrates up and down, it drives the moving toothed plates 803 to slide. Through the meshing of the rotating gear 802, multiple sets of turbulence plates 801 are synchronously deflected, dispersing the straight airflow into turbulence. This significantly increases the contact area between the gas and the adsorbent, further extending the gas residence time and greatly reducing local airflow blind spots in the bed. This ensures that the baking hot air and cooling airflow evenly cover the entire adsorption bed, achieving thorough regeneration and uniform cooling throughout the entire area.
[0028] In this embodiment: the gas storage tank 6 stores a portion of the finished gas. It should be noted that after the finished gas is purified by adsorption, most of the water vapor and impurities have been removed, and the dew point is stable at a low level, which meets the requirements for regeneration regulation. Using it as the regeneration gas can form the maximum humidity gradient, efficiently desorb the water vapor adsorbed inside the adsorbent, and the finished gas in the gas storage tank 6 can regenerate the adsorbent under maximum blockage. After purification, the finished gas is discharged from the top of the adsorption tower 301. The discharged finished gas flows in two parts. One part of the finished gas is pumped into the piston frame 501 via a gas pump, while the other part is transported out as commercial gas. The part of finished gas stored in the gas storage tank 6 is mainly used to regenerate the adsorbent in the adsorption bed 303 and to enable the drive module 5 to operate. When baking and cooling operations are required, the operator starts the gas pump and inputs part of the finished gas from the gas storage tank 6 into the piston frame 501 through the first pipe. Under the action of the gas, the piston plate 502 slides slowly inside the piston frame 501 and squeezes the return spring 506 on one side. Squeezing the piston plate 502 drives the drive tooth plate 503 on one side to slide inside the piston frame 501. The drive tooth plate 503 drives the driven tooth ring 504 to rotate and synchronously drives the adsorption bed 303 to rotate, causing the adsorption bed 303 to rotate slowly and uniformly. To ensure uniform adsorption and regeneration, during the continuous rotation of the adsorption bed 303, several pushing components 704 move synchronously, and several lifting components 703 on one side rotate synchronously and intermittently. The lifting components 703 lift the filter plate 701, generating slight vibrations, which cause the filter plate 701 to vibrate slightly up and down. The synchronous rotation of the lifting components 703 will not cause the filter plate 701 to tilt, ensuring the flatness and sealing of the filter plate 701. When the filter plate 701 moves, it slides on the outer surface of the electric magnetic rail 408 through the sliding bushing set in the middle, avoiding wear or jamming caused by the sliding of the filter plate 701 on the electric magnetic rail 408. It is reset by the support spring 702, automatically shaking off the dust and impurities trapped on the surface to prevent secondary pollution. When the filter plate 701 moves, it drives the moving toothed plate 803 to vibrate slightly up and down through the connecting ring, thereby rotating the gear 802 and driving the baffle plate 801 inside the adsorption bed 303 to swing back and forth, further agitating the airflow and enhancing heat and mass transfer. When the baking or cooling operation is about to be completed, and the drive tooth plate 503 needs to be reset, the pressure relief valve of the pressure relief pipe 505 is opened. Under the action of the reset force of the reset spring 506, the drive tooth plate 503 is pushed to reset and slide. The drive tooth plate 503 discharges the finished gas inside the piston frame 501 into the adsorption tower body 301 through the pressure relief pipe 505. Together with the finished gas applied downward from the top, it flows downward. Finally, the condensate and impurity waste liquid generated during baking are discharged out of the tower in a timely manner through the bottom drain pipe. It should be noted that when the filter plate 701 moves up and down, the connecting ring also moves upward, thereby driving the lower moving toothed plate 803 to slide. However, since the connecting ring is rotatably connected to the lower part of the filter plate, the rotation of the connecting ring will not affect the trajectory of the filter plate 701 moving up and down, and the two movements do not interfere with each other. An uninterruptible power supply or backup battery can be added to the equipment to provide temporary power to other electrical components such as the air pump, ensuring that the equipment can still complete the current regeneration cycle after the external power grid is cut off, and rotate the adsorption bed 303 to the predetermined stop position.
[0029] Example 3: Reference Figures 1 to 3 As shown, the difference between this embodiment and Embodiments 1 and 2 is that the gas delivery module 2 includes a Y-shaped input gas pipe 201 and a Y-shaped output gas pipe 202, which are respectively fixedly installed on the upper and lower sides of the adsorption tower 301 on both sides. A first electric valve 203 is provided at the bifurcation point on the surface of the Y-shaped input gas pipe 201 and the Y-shaped output gas pipe 202. A pressure gauge is provided on one side of the first electric valve 203. The Y-shaped pipelines on the upper and lower sides are adapted to the parallel layout of the dual adsorption tower 301 to realize automatic switching of gas inlet and outlet. The first electric valve 203 controls the opening and closing of the gas path, and the pressure gauge monitors the pipeline pressure in real time.
[0030] Specifically, refer to Figures 1 to 3 As shown, a regeneration module 9 is provided on the surface of the support frame 1. The regeneration module 9 includes a blower 901 fixedly connected to one side of the gas storage tank 6 via an extraction pipe. A valve is provided on the outer surface of the extraction pipe. An electric heating element 902 is connected to the exhaust port of the blower 901 via a pipe. A Y-shaped regeneration gas pipe 903 is connected to the exhaust end of the electric heating element 902. A second electric valve 904 is provided at each fork on the surface of the Y-shaped regeneration gas pipe 903. One end of the Y-shaped regeneration gas pipe 903 is fixedly connected to the bend of the Y-shaped output gas pipe 202. The regeneration module 9 draws air through the blower 901 and generates high-temperature hot air through the electric heating element 902. The hot air is then diverted through the Y-shaped regeneration gas pipe 903 and sent into the adsorption tower 301 to realize automatic baking, dehumidification and regeneration of the adsorbent. The second electric valve 904 independently controls the interruption of the dual-path regeneration gas flow, which can realize single-tower regeneration and dual-tower alternating operation, and is suitable for continuous industrial production.
[0031] Specifically, refer to Figures 1 to 3 As shown, sewage pipes are fixedly installed at the bottom of the adsorption tower bodies 301 on both sides. The adsorption tower module 3 also includes gas distributors 304 set on the upper and lower sides of the support cylinder 302. A PLC controller 10 for executing cycle programs is set on the surface of the support frame 1. The PLC controller 10 is equipped with a processor module for controlling the system, a communication interface module for data exchange, and a PID calculation module. Each module set in the PLC controller 10 can preset cycle programs to realize the fully automated operation of gas adsorption, flow rate adjustment, bed plate rotation, baking regeneration, and sewage discharge switching, reducing manual intervention and improving the intelligence level of the equipment.
[0032] In this embodiment: the PLC controller 10 starts the equipment, and the processor module is responsible for logic operation, timing judgment, working condition switching decision, uniformly issuing control commands to all execution components, judging the equipment operating condition, realizing automatic start and stop, single and dual tower switching, fault judgment, and the sequence and coordination of the actions of all mechanisms such as regenerative heating. The function of the communication interface module is to collect parameters from various sensors in real time, realize signal transmission and command response between actuators, ensure data communication between various modules of the equipment, and provide real-time data sources for processor decision-making and PID calculation. The PID calculation module is used for closed-loop control of gas pipeline pressure and airflow rate through adsorption bed 303, constant temperature control of heating element 902 in regeneration process, temperature uniformity control of adsorption bed 303 during cooling stage, and stable control of outlet gas dew point.
[0033] During the purification process, the raw gas is diverted into one side of the adsorption tower 301 through the Y-shaped inlet pipe 201. After being evenly distributed by the gas distributor 304, it passes through the support cylinder 302, the filter module 7, and the adsorption bed 303. The adsorbent inside the adsorption bed 303 adsorbs and purifies the water vapor and impurities in the industrial gas. The purified gas is discharged through the Y-shaped outlet pipe 202, and part of it is diverted into the gas storage tank 6 for storage and later use. It should be noted that the gas distributor 304 is a device used in industrial processes to evenly and controllably disperse concentrated airflow from pipelines into space, transforming high-speed concentrated airflow into coverage of the target area in order to ensure uniform gas ejection. After a prolonged purification process, the raw gas passes through a dew point sensor in the operating adsorption tower 301 to detect the saturation of the adsorbent in the adsorption bed 303. When the dew point sensor detects that the inlet and outlet pressure difference threshold is greater than 0.1 MPa, it indicates that regeneration of the adsorbent in the adsorption tower 301 is required. At this time, the second electric valve 904 on the corresponding side of the Y-type regeneration gas pipe 903 is opened, leading the clean gas from the gas storage tank 6 to the blower 901. The gas is heated to a high temperature by the electric heating element 902 and then sent back into the adsorption tower 301 through the Y-type regeneration gas pipe 903, moving from top to bottom. After the baking and regeneration are completed, the electric heating... Element 902 stops heating and continues to supply room temperature clean gas to cool the adsorption bed 303. The above operations are performed simultaneously. After cooling is complete, the valve on the surface of the pressure relief pipe 505 is opened to discharge the gas inside the piston frame 501 into the adsorption tower body 301 to avoid gas waste. Then, under the action of the reset spring 506, a reset operation is performed. After cooling to the target temperature, the second electric valve 904 on the corresponding side of the Y-shaped regeneration gas pipe 903 is closed. The valve is switched to allow the tower to re-enter the adsorption state. At the same time, the other tower enters regeneration. The water vapor and impurities generated by desorption are discharged through the sewage pipe. The two towers alternate in this cycle and are automatically controlled by the PLC throughout the process.

The power supply is also common knowledge in the field. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
