Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and more specifically, to a wafer vertical grate glue condensation waste gas treatment device. Background Technology

[0002] Vertical wafer furnaces generate large amounts of high-temperature waste gas containing organic binder decomposition products and gaseous pollutants during the binder removal process. Industrially, this gas is typically cooled first through a condensation process, causing some high-boiling-point organic compounds to condense and precipitate, before further absorption or adsorption treatment. The condensed waste gas still contains a certain concentration of low-boiling-point organic compounds and fine droplets, requiring further purification through gas-liquid contact equipment such as packed towers. Existing treatment devices mostly employ fixed packed bed structures, where the porosity and packing state of the packing layer remain essentially unchanged during operation.

[0003] However, the debinding process in vertical wafer furnaces is characterized by significant intermittency and load fluctuations, revealing some shortcomings in traditional fixed-packed towers during actual operation. Under low-load conditions, the exhaust gas flow rate is small, resulting in insufficient gas phase kinetic energy. The gas flow tends to pass through local low-resistance channels within the tower cross-section, forming eccentric flow or channeling, leading to insufficient gas-liquid contact and a significant decrease in mass transfer efficiency. Under high-load conditions, the exhaust gas flow rate increases sharply, and the processing capacity of the fixed bed is limited by the packing height, making contaminant penetration prone to occur. Simply increasing the packing height leads to a significant increase in the overall pressure drop of the bed. Therefore, fixed-packed towers struggle to maintain good mass transfer efficiency, low pressure drop, and stable operation simultaneously over a wide range of load variations. Summary of the Invention

[0004] This invention provides a wafer vertical grate adhesive condensation waste gas treatment device, which solves the problems mentioned in the background art by setting a fixed packing layer and suspending a freely swaying floating packing above the fixed packing layer, so that the fixed packing layer and the floating packing can automatically switch between separation or composite states according to the changes in waste gas load.

[0005] To achieve the above objectives, the present invention provides a wafer vertical grate glue condensation waste gas treatment device, comprising an air inlet box, a spray box fixedly installed on the top of the air inlet box, a purification cylinder fixedly installed between the air inlet box and the spray box, and spray heads disposed inside the spray box for spraying and absorbing liquid. The purification cylinder contains a movable filter plate that can move up and down. After rising to a preset height, the movable filter plate rotates horizontally during its descent. A fixed packing layer is laid on the movable filter plate, and a floating packing layer is suspended above the fixed packing layer by a connecting rope. The floating packing layer is made of lightweight material.

[0006] In the above technical solution, at a relatively small air flow rate, the floating packing is suspended at the end of the connecting rope and sways under the action of airflow. After the air flow rate increases to a certain extent, the movable filter plate and the fixed packing layer are pushed upward by the airflow, and the top of the floating packing and the fixed packing layer abut against each other to form a composite bed.

[0007] Based on the above, an installation frame is snapped onto the inner wall of the purification cylinder, and a fixed cylinder is fixedly installed on the rod wall of the installation frame. The end of the connecting rope away from the floating packing passes through the fixed cylinder, and the end of the connecting rope away from the floating packing is wrapped with a knot at the top of the fixed cylinder.

[0008] A limiting sleeve is fixedly installed on the bottom surface of the fixed sleeve, and the limiting sleeve is sleeved outside the connecting rope.

[0009] The inner wall of the purification cylinder is fixedly installed with a fixed filter plate and several floating packing materials. The number of connecting ropes corresponds to the number of floating packing materials, and all the connecting ropes pass through the through holes of the fixed filter plate.

[0010] A rod is fixedly installed on the outer wall of the movable filter plate, and a guide groove is provided on the inner wall of the purification cylinder for the rod to slide.

[0011] The guide channel includes a straight channel, a turning channel, and a spiral channel that are opened on the inner wall of the purification cylinder and are connected to each other. The guide channel also includes a wedge block set on the top of the straight channel.

[0012] A support ring plate is fixedly installed on the inner wall of the purification cylinder. A rotating ring plate is rotatably installed on the top surface of the support ring plate. A damping spring is fixedly installed on the top surface of the rotating ring plate. The top of the damping spring is fixedly connected to the bottom surface of the movable filter plate.

[0013] A push plate is fixedly installed on the top surface of the movable filter plate.

[0014] An air inlet pipe is fixedly installed on the outer wall of the air inlet box, an air outlet pipe is fixedly installed on the top surface of the spray box, a water storage tank is fixedly installed on the side wall of the air inlet box, a water pump is installed on the water storage tank, the water inlet of the water pump is connected to the inside of the water storage tank, the water outlet of the water pump is connected to the spray pipe, the end of the spray pipe away from the water pump is connected to the spray head, and a demister is fixedly installed on the inner wall of the spray box, and the demister is located above the spray head.

[0015] The bottom surface of the inner wall of the air intake box is inclined, and the water storage tank is connected to the inside of the air intake box through a connecting pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This wafer vertical grate condensate exhaust gas treatment device incorporates movable filter plates that can move up and down, with a fixed packing layer laid on top. Floating packing is suspended above the fixed packing layer via connecting ropes. This allows the device to automatically switch the packing contact state according to changes in exhaust gas load. Under low load, the free movement of the floating packing enhances gas-liquid contact, while under high load, the floating packing and fixed packing layer form a composite bed to improve treatment capacity. This effectively avoids the problems of unstable mass transfer efficiency and easy penetration under high load in traditional fixed-packing towers, achieving adaptive adjustment to exhaust gas load fluctuations.

[0017] 2. In this wafer vertical grate glue condensation waste gas treatment device, the cooperation of the guide groove and the insert rod allows the movable filter plate to rotate horizontally along the spiral groove when it rises to a preset height and then descends. This causes the fixed packing layer to rearrange, achieving the effect of breaking up packing bridging and caking, and redistributing the airflow channels. This effectively avoids the problem of blockage caused by impurity deposition or liquid film adhesion in the fixed packing layer during long-term operation, ensuring that the device maintains good gas-liquid mass transfer efficiency even under low-load conditions, thus improving operational stability and service life.

[0020] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] Example 1, Reference Figures 1-3 As shown, the present invention discloses a wafer vertical grate glue condensation waste gas treatment device, including an air inlet box 100, a spray box 101 fixedly installed on the top of the air inlet box 100, a purification cylinder 104 fixedly installed between the air inlet box 100 and the spray box 101, and a spray head 107 disposed inside the spray box 101 for spraying and absorbing liquid.

[0022] It should be noted that the aforementioned air inlet box 100 is used to receive the exhaust gas after condensation treatment following the application of adhesive in the vertical wafer furnace. The spray box 101 is located above the purification cylinder 104, and the spray head 107 sprays absorbent liquid downwards. Under the action of gravity, the absorbent liquid falls into the purification cylinder 104, forming a countercurrent contact with the exhaust gas flowing from bottom to top. The purification cylinder 104 serves as the main area for gas-liquid contact.

[0023] Combination Figure 3 As shown, the interior of the purification cylinder 104 is equipped with a movable filter plate 200 that can move up and down. After rising to a preset height, the movable filter plate 200 will rotate horizontally during its descent. A fixed packing layer 201 is laid on the movable filter plate 200, and a floating packing 202 is suspended above the fixed packing layer 201 by a connecting rope 205. The floating packing 202 is made of lightweight material.

[0024] The fixed packing layer 201 can be made of structured packing materials such as metal or plastic, or it can be made of bulk packing materials such as Pall rings, Raschig rings, stepped rings, or rectangular saddle rings, which are laid on the movable filter plate 200 to form a packing layer of a certain thickness. The floating packing 202 can be made of lightweight materials to make it easier to sway under low-load airflow. For example, the floating packing 202 can be made of lightweight plastics, foamed materials, hollow spheres, or lightweight ceramics, and its shape can be spherical, annular, polyhedral, or irregular. Among them, hollow plastic rings or multi-faceted hollow spheres are common choices, as they are lightweight, have a large surface area, and can have holes or grooves on their surface to facilitate gas-liquid contact. The floating packing 202 can also be made of lightweight materials with hydrophilic surface treatment to improve the spreading ability of the absorbent liquid on its surface.

[0025] It should be noted that the vertical movement and horizontal rotation of the movable filter plate 200 are achieved through the cooperation between the guide groove 301 on the inner wall of the purification cylinder 104 and the insertion rod 300 on the outer wall of the movable filter plate 200. The design of the guide groove 301 allows the movable filter plate 200 to rise smoothly along the straight groove 306 when it rises. When it reaches the preset height, the wedge block 309 contacts the insertion rod 300 on the outer wall of the movable filter plate 200, triggering the insertion rod 300 to move into the turning groove 307. Subsequently, during the descent of the movable filter plate 200, the insertion rod 300 slides along the spiral groove 308, driving the movable filter plate 200 to rotate horizontally. This design can destroy the bridging or compaction structure that may form in the fixed packing layer 201 during operation, maintain the loose state of the fixed packing layer 201, and improve the gas-liquid mass transfer efficiency.

[0026] The quantity and distribution of the floating packing 202, as well as the length of the connecting rope 205, have been optimized to ensure that when the movable filter plate 200 rises, several floating packing 202s can uniformly contact the top of the fixed packing layer 201, forming a uniform composite bed. When the movable filter plate 200 descends, the floating packing 202s separate from the top of the fixed packing layer 201, and the floating packing 202s sway freely under the action of airflow, increasing the dynamics of gas-liquid contact.

[0027] The floating packing 202 has a first state and a second state. In the first state, the floating packing 202 can move freely under the action of airflow. At this time, the exhaust gas flow rate is relatively small (low load condition). The movement of the floating packing 202 can agitate the airflow, making the absorbent liquid spread more evenly on the surface of the fixed packing layer 201 and avoiding liquid concentration in the flow channel. In the second state, the floating packing 202 contacts the top of the fixed packing layer 201 to form a composite bed. At this time, the exhaust gas flow rate is relatively large (high load condition). The composite bed is equivalent to increasing the height of the fixed packing layer 201, improving the exhaust gas treatment capacity of the device, while avoiding the problem of excessive pressure drop caused by simply increasing the packing height, and realizing adaptive adjustment to exhaust gas load fluctuations.

[0028] Specifically, when the exhaust gas flow rate is low, the lifting force of the airflow on the movable filter plate 200 and the fixed packing layer 201 is insufficient to keep them in contact with the floating packing 202, and the floating packing 202 is in the first state. At this time, the floating packing 202 is suspended by the connecting rope 205, and under the action of weak airflow, it sways, rotates, or collides with each other, thereby creating local disturbances under low gas velocity conditions and increasing the chance of gas-liquid contact. When the exhaust gas flow rate increases to a certain extent, the lifting force of the airflow on the movable filter plate 200 and the fixed packing layer 201 exceeds their own weight, and the movable filter plate 200 and the fixed packing layer 201 are pushed upward and come into contact with the floating packing 202, and the floating packing 202 enters the second state. At this time, the floating packing 202 and the fixed packing layer 201 together form a composite bed with a greater height, which is equivalent to increasing the overall height of the fixed packing layer 201, thereby improving the treatment capacity under high load conditions.

[0029] pass Figure 4 and Figure 5 As shown, an installation bracket 203 is snapped onto the inner wall of the purification cylinder 104, and a fixed cylinder 204 is fixedly installed on the rod wall of the installation bracket 203. The end of the connecting rope 205 away from the floating packing 202 passes through the fixed cylinder 204, and the end of the connecting rope 205 away from the floating packing 202 is wrapped with a knot 206 at the top of the fixed cylinder 204.

[0030] Furthermore, the fixed cylinder 204 is fixedly connected to the mounting bracket 203, and the connecting rope 205 passes through the inside of the fixed cylinder 204, with the falling length of the connecting rope 205 limited by the knot 206. In this way, the floating packing 202 will not come out of the fixed cylinder 204 when it swings freely, and the length of the connecting rope 205 also determines the maximum distance between the floating packing 202 and the fixed packing layer 201 under low load conditions.

[0031] A limiting cylinder 207 is fixedly installed on the bottom surface of the fixed cylinder 204, and the limiting cylinder 207 is sleeved on the outside of the connecting rope 205.

[0032] The limiting cylinder 207 constrains the swing amplitude of the connecting rope 205. When the floating packing 202 sways under the action of airflow, the connecting rope 205 will swing below the fixed cylinder 204. The limiting cylinder 207 can prevent several connecting ropes 205 from getting tangled or knotted due to excessive swing amplitude, ensuring that each floating packing 202 always moves within the preset range of motion.

[0033] A fixed filter plate 208 is fixedly installed on the inner wall of the purification cylinder 104. Several floating packing materials 202 are provided. The number of connecting ropes 205 corresponds to the number of floating packing materials 202. Several connecting ropes 205 pass through the through holes of the fixed filter plate 208.

[0034] Specifically, the fixed filter plate 208 is used to limit the movement area of ​​the floating packing 202. The floating packing 202 is located below the fixed filter plate 208, and the connecting rope 205 passes through the through hole on the fixed filter plate 208 and is connected to the mounting bracket 203. When the floating packing 202 is pushed upward by the airflow in the second state, the fixed filter plate 208 can prevent it from moving upward further, thus preventing the floating packing 202 from entering the spray box 101 or blocking the air outlet pipe 103.

[0035] Combination Figure 6 and Figure 8 As shown, a rod 300 is fixedly installed on the outer wall of the movable filter plate 200, and a guide groove 301 for the rod 300 to slide is provided on the inner wall of the purification cylinder 104. Combined with... Figure 9 As shown, the guide groove 301 includes a straight groove 306, a turning groove 307 and a spiral groove 308 that are formed on the inner wall of the purification cylinder 104 and are connected to each other. The guide groove 301 also includes a wedge block 309 that is fixedly installed on the top of the straight groove 306.

[0036] The insert rod 300 is fixed to the outer wall of the movable filter plate 200 and inserted into the guide groove 301. When the movable filter plate 200 is subjected to external force and moves up and down, the insert rod 300 slides along the guide groove 301, thereby guiding the movable filter plate 200 to move in a preset manner. It should also be noted that at least three insert rods 300 are provided, and the number and position of the guide grooves 301 correspond to the number of insert rods 300. The guide grooves 301 are connected end to end to ensure the stability of the movable filter plate 200 when it slides up and down.

[0037] Furthermore, the guide groove 301 is formed by the connection of the straight groove 306, the turning groove 307, and the spiral groove 308, creating a unidirectional circulation path. When the movable filter plate 200 rises, the insert rod 300 slides upward along the straight groove 306; after reaching the top of the straight groove 306, the insert rod 300 enters the turning groove 307 under the guidance of the wedge block 309. When the movable filter plate 200 subsequently descends, the insert rod 300 cannot return along the original path but enters the spiral groove 308, causing the movable filter plate 200 to rotate horizontally during its descent. In this way, each time the movable filter plate 200 completes one rise and fall, it will cause the fixed packing layer 201 to rotate horizontally at a certain angle, achieving the purpose of breaking the packing agglomeration and redistributing the airflow channels.

[0038] It should also be noted that, since the packing material in the fixed packing layer 201 is larger than that in the guide groove 301, the packing material in the fixed packing layer 201 will not get stuck in the guide groove 301 when it moves up and down with the movable filter plate 200.

[0039] Back Figure 7As shown, a support ring plate 305 is fixedly installed on the inner wall of the purification cylinder 104, a rotating ring plate 303 is rotatably installed on the top surface of the support ring plate 305, a damping spring 304 is fixedly installed on the top surface of the rotating ring plate 303, and the top end of the damping spring 304 is fixedly connected to the bottom surface of the movable filter plate 200.

[0040] The support ring plate 305 provides a supporting base for the movable filter plate 200, and the rotating ring plate 303 can rotate on the support ring plate 305. A damping spring 304 connects the rotating ring plate 303 and the movable filter plate 200. When the movable filter plate 200 descends, the damping spring 304 is compressed, and simultaneously, the rotating ring plate 303 rotates with the movable filter plate 200, preventing the damping spring 304 from generating excessive resistance due to torsional deformation. The damping spring 304 consists of a spring coil and a viscoelastic damping layer covering the outer circumference of the spring coil, making the movable filter plate 200 more stable during lifting and lowering.

[0041] Combination Figure 6 and Figure 7 As shown, a pusher plate 302 is fixedly installed on the top surface of the movable filter plate 200.

[0042] When the movable filter plate 200 rotates horizontally during its descent, the pusher plate 302 can assist in moving the packing in the fixed packing layer 201 to rotate horizontally at a certain angle, following the rotation of the movable filter plate 200.

[0043] Reference Figure 1 and Figure 2 As shown, an air inlet pipe 102 is fixedly installed on the outer wall of the air inlet box 100, an air outlet pipe 103 is fixedly installed on the top surface of the spray box 101, a water storage tank 105 is fixedly installed on the side wall of the air inlet box 100, a water pump (not shown in the figure) is installed on the water storage tank 105, the water inlet end of the water pump is connected to the inside of the water storage tank 105, the water outlet end of the water pump is connected to the spray pipe 106, the end of the spray pipe 106 away from the water pump is connected to the spray head 107, and a demister 108 is fixedly installed on the inner wall of the spray box 101, and the demister 108 is located above the spray head 107.

[0044] The exhaust gas enters the intake chamber 100 through the intake pipe 102, then rises into the purification cylinder 104. After contacting the absorbent liquid sprayed from the spray head 107, the fixed packing layer 201, and the floating packing layer 202, it continues to rise into the spray chamber 101. After passing through the demister 108 to remove any entrained liquid droplets, it is discharged from the exhaust pipe 103. The demister 108 prevents excessive liquid from being carried in the exhaust gas, reducing the risk of corrosion and blockage in subsequent pipelines.

[0045] The bottom surface of the inner wall of the air intake box 100 is inclined, and the water storage tank 105 is connected to the interior of the air intake box 100 through the connecting pipe 109.

[0046] Furthermore, the bottom of the air inlet box 100 is inclined, which allows the spray liquid to flow back to the air inlet box 100 and collect along the inclined bottom surface, and then flow into the water storage tank 105 through the connecting pipe 109, so as to realize the recycling of the absorbent liquid.

[0047] Working principle: During operation, the condensate fumes from the wafer vertical grate furnace enter the inlet chamber 100 through the inlet pipe 102. After forming a relatively stable airflow within the inlet chamber 100, the fumes rise into the purification cylinder 104. Simultaneously, a water pump delivers the absorbent liquid from the water storage tank 105 to the spray head 107 via the spray pipe 106. The absorbent liquid is then sprayed downwards into the purification cylinder 104 by the spray head 107. Under the influence of gravity, the absorbent liquid flows downwards, forming a countercurrent contact with the upward-flowing fumes.

[0048] Under low-load conditions, the exhaust gas flow rate is small, and the lifting force of the airflow on the movable filter plate 200 and the fixed packing layer 201 is insufficient to overcome their own weight, so the movable filter plate 200 is in a lower position. At this time, the floating packing 202 is suspended above the fixed packing layer 201 by the connecting rope 205, and is separated from the fixed packing layer 201. Under the action of weak airflow, it sways, rotates or collides with each other, creating local disturbances and increasing the chance of gas-liquid contact.

[0049] Under high-load conditions, the exhaust gas flow rate increases, and the lifting force of the airflow on the movable filter plate 200 and the fixed packing layer 201 increases, pushing the movable filter plate 200 upward. During the upward movement of the movable filter plate 200, the insertion rod 300 slides upward along the straight groove 306 of the guide groove 301. When the movable filter plate 200 rises to the preset height, the insertion rod 300 reaches the top of the straight groove 306 and enters the turning groove 307 under the guidance of the wedge block 309. At the same time, the floating packing 202 contacts the top of the fixed packing layer 201 and forms a composite bed under the limiting action of the fixed filter plate 208, which is equivalent to increasing the effective height of the packing section, thereby improving the treatment capacity under high load and preventing pollutants from penetrating.

[0050] After the exhaust gas flow rate decreases, the movable filter plate 200 descends under the action of gravity. The insertion rod 300 cannot return along the original path but enters the corresponding spiral groove 308, causing the movable filter plate 200 to rotate horizontally during its descent. Thus, each time the movable filter plate 200 completes its ascent and descent, it drives the fixed packing layer 201 to rotate horizontally at a certain angle, thereby breaking up the packing agglomeration and redistributing the airflow channels.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
