Description

Technical Field

[0001] The present invention relates to the technical field of gas dehumidification, and in particular to a chemical production gas dehumidification transfer energy-saving drying device and a method thereof. Background Art

[0002] In chemical production, gas dehumidification is a key link in ensuring product quality and process stability. It effectively removes moisture from the gas through absorption, adsorption or cooling condensation. Common methods include using solid adsorbents such as molecular sieves and silica gel, or freeze-drying, liquid absorption and other technologies. Dehumidification can not only prevent equipment corrosion and pipeline blockage, but also improve chemical reaction efficiency and ensure the purity and performance of the final product.

[0003] The patent with application number CN202010252110.2 discloses a gas supply drying equipment for chemical production, including, by installing a gas supply device connected to the interior of the drying box on the outside of the drying box, and using the piston syringe to press down to continuously introduce gas into the drying box. The gas introduced into the drying box is first heated, so that the moisture in the gas forms water vapor. The water vapor is introduced into the desiccant pipe and encounters a water cooling mechanism for liquefaction. The water droplets formed by liquefaction flow downstream under the action of gravity through multiple drainage cotton threads and are adsorbed and dried by the desiccant layer.

[0004] However, traditional chemical gas dehumidification equipment has obvious shortcomings when dealing with highly corrosive, high-humidity and impurity-containing gases. When using a fixed adsorption bed, the acidic components in the gas can easily corrode the adsorption material, causing the adsorption capacity to decay rapidly, requiring frequent shutdowns for cleaning or replacement, seriously interfering with the chemical continuous production process. In addition, the problem of uneven gas distribution is prominent, and high-speed airflow directly impacts the adsorption layer to form a channeling effect. Local adsorption cotton is saturated prematurely, while the remaining areas are not fully utilized, which will lead to large fluctuations in the overall dehumidification rate and substandard outlet gas humidity.

[0005] In view of this, we propose a chemical production gas dehumidification transfer energy-saving drying device and method. Summary of the Invention

[0006] The object of the present invention is to provide a chemical process gas dehumidification transfer energy-saving drying device and method thereof to solve the problems raised in the above background technology.

The slider can drive the protruding rod to rotate the rotating shaft, and then drive the rotating part to rotate to adjust the position of the adsorption cotton. The water guide device includes a water guide cover that can be driven upward by a slider. The top surface of the water guide cover is provided with a plurality of water holes. The top of the water guide cover extends above the drainage groove and squeezes the adsorption cotton, allowing the moisture in the adsorption cotton to flow into the inside of the water guide cover.

[0008] In the technical solution of the present invention, a ring wall through groove corresponding to the air outlet groove is provided on the inner ring wall of the outer ring, and air holes are provided at positions corresponding to the air outlet grooves on the inner bottom surface of the outer ring, and partitions are integrally formed on both sides of the air holes on the inner wall of the outer ring.

[0009] In the technical solution of the present invention, an air inlet hood for introducing chemical gas is fixedly snapped onto the top opening of the circular cover, and the connecting ring is respectively welded and fixed to the circular cover and the outer ring.

[0010] In the technical solution of the present invention, the ventilation duct further comprises a ventilation frame fixedly connected to the outside of the air vents and an exhaust hood welded and connected to the bottom of the plurality of ventilation frames.

[0011] In the technical solution of the present invention, the rotating part also includes a ring piece fixedly connected to the top surface of the ring frame by screws, and a ring tooth welded and fixed to the top surface of the ring piece, and the adsorption cotton is adhered and fixed to the ring frame.

[0012] In the technical solution of the present invention, the air-guiding device also includes a motor and a limit rod for limiting the movement range of the slider. The motor is fixedly connected to the top surface of the exhaust hood by bolts. The upper and lower ends of the reciprocating screw are respectively clamped and fixed to the fan blades and the output shaft of the motor. The fan blades are rotatably connected to the inside of the circular hood.

[0013] In the technical solution of the present invention, the transmission mechanism also includes a bending plate, a telescopic rod arranged on the bottom surface of the bending plate, a first spring sleeved on the outside of the telescopic rod, and shaft teeth clamped to the top of the rotating shaft and meshing with the ring teeth.

[0014] In the technical solution of the present invention, the inner end of the bending plate is provided with a circular hole for the reciprocating screw rod and the limit rod to pass through, and the upper and lower ends of the telescopic rod are respectively clamped and fixed with the bottom end of the bending plate and the top surface of the exhaust hood. The elastic force provided by the first spring pushes the bending plate to move upward, the protruding rod is welded and fixed to the bending plate, and a cam groove is provided on the outer side wall of the rotating shaft for guiding the movement of the protruding rod end.

[0015] In the technical solution of the present invention, the water-guiding device also includes a circular plate that provides a fixed platform for several water-guiding covers, several second springs welded to the top surface of the circular plate, a water storage tank arranged below the circular plate, and a sleeve welded to the top surface of the water storage tank. The top end of the second spring is welded to the bottom surface of the outer ring. The water storage tank is fixedly connected to the inner walls of several ventilation frames by bolts, and the bottom end convex tube of the water-guiding cover is slidably connected to the inside of the sleeve.

[0016] On the other hand, the present invention also provides a method for dehumidifying and drying chemical process gas, using the above-mentioned chemical process gas dehumidifying and drying device, comprising the following steps: S1. First, the exhaust pipe of the chemical production equipment is fixedly connected to the air inlet cover, and the motor in the air guide device is started at the same time, driving the reciprocating screw to rotate while allowing the guide fan blades to rotate in the circular cover; S2. The chemical gas is then accelerated and thrown out by the fan blades, and enters the interior of the adsorption cotton in the rotating part through the air outlet slot, where the hydrophobic breathable membrane and the hydrophilic fiber layer embedded inside the adsorption cotton adsorb the water molecules in the gas; S3. The chemical gas then enters the outer ring through the ring wall groove and enters the interior of the ventilation frame through the air vents. The dehumidified gas is then discharged by the exhaust hood and further dried by the heating mechanism in the subsequent pipeline. S4. The continuously rotating reciprocating screw drives the slider to move up and down outside the limit rod. The bending plate first moves downward after being squeezed by the slider, and then resets due to the elastic force of the first spring, which changes the contact position between the convex rod and the cam groove, causing the rotating shaft to rotate one circle, thereby driving the entire rotating part to rotate. S5. After the rotating part rotates, the positions of the plurality of adsorption cottons are adjusted, and the adsorption cottons that have absorbed too much moisture are moved to the top of the drainage trough; S6. Subsequently, when the slider squeezes the circular plate upward, the end of the water guide cover enters the interior of the ring frame through the drainage groove and squeezes the adsorption cotton. The water inside it enters the interior of the water guide cover through the water hole, and then flows into the interior of the water storage tank through the convex pipe at the bottom of the water guide cover.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This chemical production gas dehumidification transfer energy-saving drying device and method uses a single motor to drive the reciprocating screw and transmission mechanism to work together, driving the adsorption cotton to periodically rotate and switch working positions, and simultaneously triggering the water guide shield to accurately squeeze and drain the saturated adsorption cotton. The adsorption, transfer, and dehydration processes are integrated into a continuous cycle, eliminating the need to stop the machine to replace the adsorption material. This significantly improves the long-term operational reliability of the device in chemical corrosive gas environments and is suitable for high-humidity, high-flow production scenarios.

[0018] 2. This chemical production gas dehumidification transit energy-saving drying device and method, the air guide fan blades of the air guide device rotate at high speed with the reciprocating screw, centrifugally accelerating the gas into the air outlet slot, evenly penetrating the adsorption cotton, and cooperating with the multi-stage diffusion channel formed by the air vents and partitions to force the gas to disperse and extend the contact time. Combined with the layered guide structure, the gas contact time is extended, ensuring sufficient moisture adsorption, avoiding local saturation, and improving the overall dehumidification rate and dry gas quality.

Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention. See also Figures 1-10 As shown, this embodiment provides a technical solution: A chemical production gas dehumidification transfer energy-saving drying device includes a ventilation pipe 100, an air guide device 200 arranged inside the ventilation pipe 100, a transmission mechanism 300 arranged outside the air guide device 200, and a water guide device 400 for drainage.

[0021] In this embodiment, Figure 2-Figure 5 As shown, the ventilation duct 100 includes a circular cover 110, an outer ring 120 for discharging gas, a connecting ring 140 arranged outside the circular cover 110, and a rotating part 150 for dehumidification. A plurality of regularly distributed air outlet slots 111 are provided on the outer wall of the circular cover 110, and drainage slots 141 staggered with the air outlet slots 111 are provided on the top surface of the connecting ring 140.

[0022] Specifically, a ring wall through groove 121 corresponding to the air outlet groove 111 is opened on the inner ring wall of the outer ring 120, and air holes 122 are opened at positions corresponding to the air outlet groove 111 on the inner bottom surface of the outer ring 120. The inner wall of the outer ring 120 is integrally formed with partitions 123 on both sides of the air holes 122.

[0023] Furthermore, an air inlet cover 130 for introducing chemical gas is fixedly snapped onto the top opening of the circular cover 110 , and a connecting ring 140 is respectively welded and fixed to the circular cover 110 and the outer ring 120 .

[0024] Furthermore, the ventilation duct 100 further includes a ventilation frame 160 fixedly connected to the outside of the air vents 122 and an exhaust cover 170 welded and connected to the bottom of the ventilation frames 160 .

[0025] Furthermore, after the exhaust pipe of the chemical production equipment is fixedly connected to the air inlet hood 130, the gas enters the interior of the circular hood 110, and after entering the rotating part 150 through the air outlet groove 111, it can enter the interior of the outer ring 120 through the annular wall groove 121, and then be sent into the ventilation frame 160 through the air vent 122, and then be discharged from the exhaust hood 170.

[0026] In this embodiment, Figure 6 As shown, the rotating portion 150 includes a ring frame 151 and a plurality of regularly distributed adsorption cottons 154 .

[0027] Specifically, the rotating part 150 also includes a ring piece 152 fixedly connected to the top surface of the ring frame 151 by screws, a ring tooth 153 welded and fixed to the top surface of the ring piece 152, and an adsorption cotton 154 adhered and fixed to the ring frame 151.

[0028] Furthermore, after the rotating portion 150 rotates, the positions of the absorbent cottons 154 are adjusted, so that the absorbent cottons 154 that have absorbed too much moisture move to above the drain groove 141 , and the dry absorbent cottons 154 move to between the air outlet groove 111 and the annular wall groove 121 .

[0029] In this embodiment, Figure 7 As shown, the air guide device 200 includes a reciprocating screw 220, a fan guide blade 230 arranged at the top of the reciprocating screw 220, and a slider 240 sleeved on the outside of the reciprocating screw 220. The fan guide blade 230 will accelerate the chemical gas into the adsorption cotton 154 outside the air outlet slot 111 as the reciprocating screw 220 rotates, thereby adsorbing moisture in the gas.

[0030] Specifically, the air guide device 200 also includes a motor 210 and a limit rod 250 for limiting the moving range of the slider 240. The motor 210 is fixedly connected to the top surface of the exhaust hood 170 by bolts. The upper and lower ends of the reciprocating screw 220 are respectively clamped and fixed to the fan blades 230 and the output shaft of the motor 210. The fan blades 230 are rotatably connected to the inside of the circular cover 110.

[0031] Furthermore, after the motor 210 is started, it drives the reciprocating screw 220 to rotate, while allowing the fan blades 230 to rotate in the circular cover 110, and the slider 240 also reciprocates up and down outside the bidirectional thread groove on the reciprocating screw 220.

[0032] In this embodiment, Figure 8 As shown, the transmission mechanism 300 includes a protruding rod 320 and a rotating shaft 350 disposed outside the protruding rod 320 . The slider 240 can drive the protruding rod 320 to rotate the rotating shaft 350 , thereby driving the rotating part 150 to rotate and adjust the position of the adsorption cotton 154 .

[0033] Specifically, the transmission mechanism 300 also includes a bending plate 310, a telescopic rod 330 arranged on the bottom surface of the bending plate 310, a first spring 340 sleeved on the outside of the telescopic rod 330, and a shaft tooth 360 clamped on the top of the rotating shaft 350 and meshing with the ring tooth 153.

[0034] Furthermore, the inner ends of the bending plate 310 are provided with circular holes for the reciprocating screw rod 220 and the limit rod 250 to pass through, and the upper and lower ends of the telescopic rod 330 are respectively clamped and fixed to the bottom end of the bending plate 310 and the top surface of the exhaust hood 170. The elastic force provided by the first spring 340 pushes the bending plate 310 to move upward, and the protruding rod 320 is welded and fixed to the bending plate 310. A cam groove 351 is provided on the outer wall of the rotating shaft 350 for guiding the movement of the end of the protruding rod 320.

[0035] Furthermore, the continuously rotating reciprocating screw 220 will drive the slider 240 to move back and forth up and down on the outside of the limit rod 250. The bending plate 310 first moves downward after being squeezed by the slider 240, and then resets by the elastic force of the first spring 340, so that the contact position between the protruding rod 320 and the cam groove 351 changes, and the rotating shaft 350 rotates one circle, and then the rotating shaft teeth 360 come into contact with the ring teeth 153, driving the rotating part 150 to rotate as a whole.

[0036] In this embodiment, Figure 9-10 As shown, the water guide device 400 includes a water guide cover 410 that can be driven upward by the slider 240. A plurality of water holes 411 are opened on the top surface of the water guide cover 410. The top of the water guide cover 410 extends above the drainage groove 141 and squeezes the adsorption cotton 154, allowing the water in the adsorption cotton 154 to flow into the interior of the water guide cover 410.

[0037] Specifically, the water-guiding device 400 further includes a circular plate 420 that provides a fixed platform for the water-guiding covers 410, a plurality of second springs 430 welded to the top surface of the circular plate 420, a water storage tank 440 disposed below the circular plate 420, and a sleeve 450 welded to the top surface of the water storage tank 440. The top end of the second spring 430 is welded to the bottom surface of the outer ring 120, the water storage tank 440 is fixedly connected to the inner wall of the ventilation frames 160 by bolts, and the bottom end convex tube of the water-guiding cover 410 is slidably connected to the inside of the sleeve 450.

[0038] Furthermore, when the slider 240 squeezes the circular plate 420 upward, the end of the water guide cover 410 enters the interior of the ring frame 151 through the drainage groove 141 and squeezes the adsorption cotton 154. The water inside the water guide cover 410 enters the interior of the water guide cover 410 through the water through hole 411, and then flows into the interior of the water storage tank 440 through the convex tube at the bottom end of the water guide cover 410. After the slider 240 moves downward, the second springs 430 drive the circular plate 420 downward under the action of their own elastic force, thereby resetting the water guide cover 410. The present invention also provides a method for dehumidifying and drying chemical process gas, using the above-mentioned dehumidifying and drying device for energy-saving chemical process gas, comprising the following steps: S1. First, the exhaust pipe of the chemical production equipment is fixedly connected to the air inlet cover 130, and the motor 210 in the air guide device 200 is started at the same time, driving the reciprocating screw 220 to rotate while allowing the guide fan blades 230 to rotate in the circular cover 110; S2. The chemical gas is then accelerated and thrown out by the fan blades 230 and enters the interior of the adsorption cotton 154 in the rotating part 150 through the air outlet slot 111. The hydrophobic breathable membrane and the hydrophilic fiber layer embedded in the adsorption cotton 154 adsorb the water molecules in the gas. S3. The chemical gas then enters the outer ring 120 through the ring wall groove 121 and enters the interior of the ventilation frame 160 through the air vent 122. The dehumidified gas is then discharged by the exhaust hood 170 and further dried by the heating mechanism in the subsequent pipeline. S4. The continuously rotating reciprocating screw 220 drives the slider 240 to move up and down outside the limiting rod 250. The bending plate 310 first moves downward after being squeezed by the slider 240, and then returns to its original position due to the elastic force of the first spring 340. This causes the contact position between the protruding rod 320 and the cam groove 351 to change, causing the rotating shaft 350 to rotate one circle, thereby driving the rotating part 150 to rotate as a whole. S5. After the rotating part 150 rotates, the positions of the plurality of adsorbent cottons 154 are adjusted, so that the adsorbent cottons 154 that have absorbed too much moisture are moved to the top of the drainage groove 141. S6. Subsequently, when the slider 240 squeezes the circular plate 420 to move upward, the end of the water guide cover 410 enters the interior of the ring frame 151 through the drainage groove 141 and squeezes the adsorption cotton 154. The water inside it enters the interior of the water guide cover 410 through the water hole 411, and then flows into the interior of the water storage tank 440 through the convex pipe at the bottom end of the water guide cover 410.
