Description

Technical Field

[0001] The invention relates to the technical field of air drying, and in particular to an air drying device and method for sulfonation. Background Art

[0002] Sulfonation reactions usually need to be carried out in an anhydrous or low-moisture environment to prevent moisture from reacting with reactants (such as sulfur trioxide) to form sulfuric acid, thereby affecting the quality of the sulfonated product. Therefore, it is necessary to remove moisture from the air used for the sulfonation reaction by adsorption, filtration, etc. to achieve the dryness required for the sulfonation reaction.

[0003] A Chinese patent application with publication number CN118161961A discloses an air treatment device and a low dew point sulfonation air treatment system, wherein the air treatment device includes a dryer, a first distributor and a second distributor, the dryer having an inlet and an outlet, and a partition plate extending from the inlet to the outlet is provided inside the dryer, and the partition plate divides the internal space of the dryer into a plurality of independent drying zones; the first distributor is installed at the inlet of the dryer, and is provided with a first gas inlet and a second gas outlet; the second distributor is installed at the outlet of the dryer, and is provided with a first gas outlet and a second gas inlet; wherein the first distributor and the second distributor are coaxially arranged and configured to rotate synchronously relative to the dryer under the drive of an external driving mechanism.

[0004] In the above patent application document, the first gas inlet is connected to the first gas outlet through the drying area to form a drying path, and the second gas inlet is connected to the second gas outlet through the drying area to form a regeneration path. The air to be treated enters from the first gas inlet and is discharged from the first gas outlet, and the regenerated hot air enters from the second gas inlet and is discharged from the second gas outlet. When the drying area corresponding to the drying path needs to be regenerated, the first distributor and the second distributor are driven to rotate synchronously to realize the switching of the drying areas corresponding to the drying path and the regeneration path.

[0005] However, the drying zone in the above application document is in a static state, and the air to be treated flows from bottom to top, which causes the adsorbent near the air inlet end to absorb too much moisture, while the moisture content of the adsorbent at the air outlet end is relatively small, resulting in poor air drying effect of the adsorbent; moreover, since the regenerated hot air flows from top to bottom, the adsorbent with a higher moisture content at the bottom is the last to contact the hot air, resulting in poor drying regeneration effect of the adsorbent at the bottom, and since the air to be treated flows from bottom to top, the moisture content of the bottom adsorbent will be further increased, resulting in the water absorption effect of the bottom adsorbent becoming increasingly worse.

[0006] Therefore, the art needs an air drying device and method for sulfonation to solve the above problems. Summary of the invention

[0007] The present invention provides an air drying device and method for sulfonation, aiming to solve the problem that the adsorbent position of the air treatment device in the related art remains unchanged, resulting in poor adsorption effect and drying regeneration effect of the adsorbent.

[0008] On the one hand, the present invention provides an air drying device for sulfonation, comprising a drying tank and a drying assembly, wherein the drying tank is provided with an air inlet and an air outlet, the drying assembly comprises a drying cylinder arranged in the drying tank and at least two mounting boxes rotatably arranged in the drying cylinder, a drying area and a regeneration area are arranged in the drying cylinder, air vents are respectively arranged at positions corresponding to the drying area on the upper and lower end surfaces of the drying cylinder, and an air outlet and an air inlet arranged up and down are arranged at positions corresponding to the regeneration area on the outer peripheral surface of the drying cylinder; The upper and lower end surfaces of the installation box are respectively provided with through holes, and the installation box is used to place the adsorbent. The drying cylinder is provided with a driving component 1 for driving the installation box to rotate along the central axis of the drying cylinder and a driving component 2 for driving the installation box to flip. The air to be treated enters the drying tank from the air inlet 1 and enters the installation box located in the drying area. After being treated by the adsorbent in the installation box, it is discharged from the air outlet 1. The external hot air enters the regeneration area from the air inlet 2 and enters the installation box located in the regeneration area from bottom to top. After drying and regenerating the adsorbent in the installation box, it is discharged from the air outlet 2. When the installation box that needs to be regenerated rotates toward the regeneration area, the driving component 2 drives the installation box to flip 180°.

[0009] Since the air to be treated passes through the installation box from bottom to top, the moisture content in the adsorbent near the bottom of the installation box is relatively large and the adsorption capacity is relatively weak, while the moisture content in the adsorbent near the top is relatively small and the adsorption capacity is relatively strong. During regeneration, the installation box is flipped 180° to allow the hot air to contact the adsorbent with less moisture content first and then the adsorbent with more moisture content. This improves the problem of moisture generated by dry regeneration being reabsorbed by the adsorbent, improves the dry regeneration effect, and makes the adsorbent at the bottom of the installation box that has completed regeneration have the strongest adsorption capacity. When the installation box is put into use in the drying area again, the drying effect on the air is improved.

[0011] Adsorbents in a fluffy state may collide with each other during rotation, causing the adsorbents to pulverize and break, resulting in a decrease in their adsorption capacity. Therefore, the present invention provides a limiting structure, and during the movement of the installation box, the limiting structure squeezes the mesh plate, and the mesh plate squeezes the adsorbent, thereby reducing the relative movement between the adsorbents during the rotation of the installation box and extending the service life of the adsorbent.

[0015] The mesh cover and the guide plate disperse the gas, making the gas entering the installation box more evenly distributed, thereby improving the drying effect of the air and the drying and regeneration effect of the adsorbent.

[0016] Preferably, the mesh cover is elastically connected to the partition plate along the up and down directions, and the limiting structure includes a limiting groove and a limiting rib, the limiting groove is provided on the upper and lower end surfaces inside the drying cylinder, the limiting rib is fixedly connected to the mesh cover, the limiting groove and the limiting rib are respectively provided with arc-shaped pushing surfaces, and a pushing plate in contact with the adjacent mesh cover is fixedly connected to the mesh plate, when the installation box is located in the drying area and the regeneration area, the limiting rib is located in the limiting groove, when the installation box rotates and switches its position between the drying area and the regeneration area, the limiting rib is disengaged from the limiting groove, the upper and lower end surfaces inside the drying cylinder squeeze the limiting rib, the limiting rib squeezes the pushing plate through the mesh cover, and the pushing plate squeezes the mesh plate.

[0017] Preferably, each mounting box is connected to the mounting rod, and the driving assembly includes a motor and a connecting rod, the connecting rod is fixedly connected to the output end of the motor, the connecting rod passes through the drying tank and the drying cylinder and is fixedly connected to the mounting rod, and the motor drives the mounting rod to rotate through the connecting rod.

While the installation box that needs drying and regeneration rotates toward the regeneration area, the drive component 2 is controlled to drive the installation box to flip 180°.

[0022] The beneficial effects of the air drying method for sulfonation of the present invention are the same as the beneficial effects of the above-mentioned air drying device for sulfonation, which will not be described in detail here.

[0023] The beneficial effects of the present invention are as follows: since the air to be treated passes through the installation box from bottom to top, the moisture content in the adsorbent near the bottom of the installation box is relatively large and the adsorption capacity is relatively weak, while the moisture content in the adsorbent near the top is relatively small and the adsorption capacity is relatively strong. When the installation box that needs to be dried and regenerated in the present invention moves toward the regeneration area, the installation box is driven to flip 180° by driving component 2, so that the hot air first contacts the adsorbent with a lower moisture content and then contacts the adsorbent with a higher moisture content, thereby improving the problem of moisture generated by the drying and regeneration being reabsorbed by the adsorbent, improving the drying and regeneration effect, and making the adsorbent at the bottom of the installation box that has completed the regeneration have the strongest adsorption capacity. When the installation box is put into use in the drying area again, the drying effect on the air is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figures 1 to 9 As shown, an air drying device for sulfonation of the present invention comprises a frame 1, a drying tank 2 and a drying assembly. Two drying tanks 2 are provided and are symmetrically arranged on the frame 1. An air inlet 21 and an air outlet 22 are provided on the drying tank 2. The drying assembly comprises a drying cylinder 3 arranged in the drying tank 2 and four mounting boxes 4 rotatably arranged in the drying cylinder 3. Through holes are respectively arranged on the upper and lower end surfaces of the mounting box 4. Adsorbent is placed in the mounting box 4.

[0036] like Figures 3 to 6 As shown, a mounting frame is rotatably arranged inside the drying cylinder 3, and the mounting frame includes a mounting rod 5 and a mounting ring 51 which are coaxially arranged with the drying cylinder 3. The outer periphery of the mounting ring 51 is in contact with the inner circumference of the drying cylinder 3, and partition plates 52 are arranged at intervals on the outer periphery of the mounting rod 5. An installation space for placing the installation box 4 is formed between two adjacent partition plates 52 and the mounting ring 51.

[0037] A drying zone and a regeneration zone are arranged in the drying cylinder 3. Ventilation holes 31 are respectively provided on the upper and lower end surfaces of the drying cylinder 3 at positions corresponding to the drying zone. An air outlet 32 ​​and an air inlet 33 arranged up and down are provided on the outer peripheral surface of the drying cylinder 3 at positions corresponding to the regeneration zone.

[0038] When drying air, the air to be treated enters the drying tank 2 from the air inlet 1 21, enters the drying zone through the vent hole 31 on the drying cylinder 3, and then enters the installation box 4 located in the drying zone. After being treated by the adsorbent in the installation box 4, the air is discharged from the air outlet 1 22. When regenerating the adsorbent in the installation box 4, the external hot air enters the regeneration zone from the air inlet 2 33, and enters the installation box 4 located in the regeneration zone from bottom to top. After drying and regenerating the adsorbent in the installation box 4, the air is discharged from the air outlet 2 32.

[0039] The drying cylinder 3 is provided with a driving assembly 1 for driving the installation box 4 to rotate along the central axis of the drying cylinder 3 and a driving assembly 2 for driving the installation box 4 to flip. When the installation box 4 in the drying area needs to be replaced, the driving assembly 1 is controlled to drive the mounting frame to rotate, and the mounting frame drives the installation box 4 to rotate, so that the installation box 4 that has completed regeneration is rotated to the drying area, and the installation box 4 that needs to be regenerated is rotated to the regeneration area.

[0040] When the installation box 4 that needs to be regenerated rotates toward the regeneration zone, the driving component 2 drives the installation box 4 to flip 180°. Since the air to be treated passes through the installation box 4 from bottom to top, the moisture content in the adsorbent near the bottom of the installation box 4 is relatively large and the adsorption capacity is relatively weak, while the moisture content in the adsorbent near the top is relatively small and the adsorption capacity is relatively strong. During regeneration, the installation box 4 is flipped 180° to allow the hot air to contact the adsorbent with less moisture content first, and then contact the adsorbent with more moisture content. This improves the problem of moisture generated by dry regeneration being reabsorbed by the adsorbent, improves the dry regeneration effect, and makes the adsorbent at the bottom of the installation box 4 that has completed regeneration have the strongest adsorption capacity. When the installation box 4 is put into use in the drying zone again, the drying effect on the air is improved.

[0041] like Figure 6 and Figure 7 As shown, the installation box 4 includes an installation frame 41 and two mesh plates 42 arranged in the installation frame 41 from top to bottom. The two mesh plates 42 are slidably connected to the installation frame 41 in the up-down direction, and the two mesh plates 42 are elastically connected by elastic members. As an example, the elastic member is an elastic telescopic rod 43, and the two ends of the elastic telescopic rod 43 are respectively fixedly connected to the corresponding mesh plates 42. A limiting structure is set between the mesh plates 42 and the drying cylinder 3. When the installation box 4 rotates and switches positions between the drying area and the regeneration area, the limiting structure squeezes the two mesh plates 42 to move in a direction close to each other. When the installation box 4 is located in the drying area or the regeneration area, the limiting structure cancels the squeezing of the mesh plates 42.

[0042] The adsorbent should be kept in a fluffy state during normal operation to prevent the pores inside the adsorbent particles from being compressed and affecting the adsorption performance. Therefore, when the installation box 4 is in the drying area and the regeneration area, the mesh plate 42 is not squeezed, and the adsorbent between the mesh plates 42 is in a fluffy state. However, the adsorbents in a fluffy state will collide with each other during rotation, causing the adsorbent to pulverize and break, etc., resulting in a decrease in its adsorption capacity. Therefore, during the process of rotating and switching positions of the installation box 4, the limiting structure squeezes the mesh plate 42, and the mesh plate 42 squeezes the adsorbent, reducing the relative movement between the adsorbents during the rotation of the installation box 4.

[0043] like Figures 4 to 9As shown, mesh covers 6 are respectively provided on the upper and lower sides of the installation box 4, and the mesh covers 6 are elastically connected to the partition plate 52 in the up and down direction. The mesh covers 6 are semi-trumpet-shaped, and when the upper and lower mesh covers 6 are in contact, the outer peripheral surface of a truncated cone is formed. A guide plate 44 is fixedly connected to the side of the installation box 4 facing the inner peripheral surface of the drying cylinder 3. The guide plate 44 is provided with a through hole, and the guide plate 44 and the mesh covers 6 are surrounded to form a space for accommodating the installation box 4. The mesh cover 6 and the guide plate 44 disperse the gas, so that the gas entering the installation box 4 is more evenly distributed, thereby improving the drying effect of the air and the drying and regeneration effect of the adsorbent.

[0044] The limiting structure includes a limiting groove 34 and a limiting convex rib 61. The limiting groove 34 is arranged on the upper and lower end surfaces inside the drying cylinder 3. The limiting convex rib 61 is fixedly connected to the mesh cover 6. The limiting groove 34 and the limiting convex rib 61 are respectively provided with an arc-shaped pushing surface 62. The mesh plate 42 is fixedly connected with a pushing plate 45 that contacts the adjacent mesh cover 6.

[0045] When the installation box 4 is located in the drying area and the regeneration area, the limiting convex rib 61 is located in the limiting groove 34. When the installation box 4 rotates and switches between the drying area and the regeneration area, the limiting convex rib 61 is disengaged from the limiting groove 34 under the extrusion and cooperation of the push surface 62, and the upper and lower end surfaces inside the drying cylinder 3 squeeze the limiting convex rib 61. The limiting convex rib 61 squeezes the push plate 45 through the mesh cover 6, and the push plate 45 squeezes the mesh plate 42. The mesh plate 42 squeezes the adsorbent to reduce the relative movement between the adsorbents. It should be noted that since the upper and lower mesh covers 6 are squeezed and contacted to form the outer peripheral surface of the truncated cone, therefore, in the process of the installation box 4 turning 180°, the push plate 45 is always in contact with the inner wall of the mesh cover 6, and the two mesh plates 42 are always in a state of being pushed, and the adsorbent in the installation box 4 will also remain in a relatively static state.

[0046] Each mounting box 4 is fixedly connected with a support rod 46 extending into the mounting rod 5, and the bottom of the drying cylinder 3 is fixedly connected with a sleeve 35 extending into the mounting rod 5. The driving assembly 1 includes a motor and a connecting rod 7, the motor is fixedly connected to the frame 1, the connecting rod 7 is fixedly connected to the output end of the motor, the connecting rod 7 penetrates the drying tank 2 and the drying cylinder 3 and is fixedly connected to the mounting rod 5, the motor drives the mounting rod 5 to rotate through the connecting rod 7, and the mounting rod 5 drives the mounting box 4 to rotate.

[0047] The second driving assembly includes a gear 8 fixedly connected to the support rod 46 and a tooth segment 9 fixedly connected to the top end surface of the sleeve 35. When the mounting box 4 rotates following the mounting rod 5, the gear 8 rotates along the tooth segment 9 when it contacts the tooth segment 9, and the rotation of the gear 8 drives the mounting box 4 to flip.

[0048] An air drying method for sulfonation, using the air drying device for sulfonation in the above embodiment, the air drying method for sulfonation comprises the following steps: The air to be treated is introduced into the air inlet 21, and the air to be treated enters the installation box 4 located in the drying area, and is discharged from the air outlet 22 after being treated by the adsorbent in the installation box 4; Hot air is introduced into the second air inlet 33, and the hot air enters the installation box 4 located in the regeneration area, dries and regenerates the adsorbent in the installation box 4, and then is discharged from the second air outlet 32; When the installation box 4 located in the drying area needs to be replaced, the motor is controlled to drive the installation rod 5 to rotate, and the installation rod 5 drives the installation frame and all the installation boxes 4 to rotate, so that the installation box 4 that has completed drying and regeneration rotates to the drying area, and the installation box 4 that needs drying and regeneration rotates to the regeneration area. In addition, in the process of the installation box 4 that needs drying and regeneration rotating to the regeneration area, the gear 8 corresponding to the installation box 4 engages with the tooth segment 9 at the top of the sleeve 35, driving the installation box 4 to flip 180°.
