Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to an adsorption and desorption device for controlling the flow direction of desorbed waste gas. Background Art

[0002] During the hose processing, a large amount of waste gas will be generated, and these waste gases are mainly VOCs. The main treatment method for this organic waste gas is to treat it by adsorption and desorption. The optimal temperature required for adsorption is between 25-35 degrees, and the optimal temperature required for desorption is between 125-135 degrees.

[0003] By passing VOCs waste gas into the tank body, it is adsorbed by the adsorption particles in the tank body. However, every time the adsorbent fails, it needs to be desorbed, and the traditional method is to use reverse ventilation to desorb. However, in the process of reverse ventilation treatment, the adsorbent at the bottom layer will be in contact with the waste gas first, so it will adsorb a large amount of VOCs waste gas. If it is desorbed, the value of the desorption itself is not high, and the time spent on desorption will also increase. Therefore, it is necessary to replace the adsorbent at the bottom layer, which is the most cost-effective way to implement. However, after the desorption of the adsorbent particles at the bottom layer is completed, it can be recycled and added to the reaction tank body in the tank body, so that the adsorbent particles at the bottom layer move to the top layer.

[0004] However, if there is no need to desorb the adsorbed particles at the bottom layer, the device will still desorb the adsorbed particles, which will result in a longer desorption time, waste more nitrogen, and increase costs.

[0005] Therefore, it is necessary to design an adsorption and desorption device that controls the flow direction of desorbed wastewater, which can automatically switch whether to desorb the adsorbed particles at the bottom layer according to the needs of desorption, thereby reducing the desorption time, saving nitrogen and reducing costs.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment: The present invention provides an adsorption and desorption device for controlling the flow direction of desorbed waste gas, such as Figure 1-5As shown, it includes a reaction tank body 1 and a heating pipe 10 installed in the reaction tank body 1, the heating pipe 10 is used to heat the adsorbed particles in the reaction tank body 1, the reaction tank body 1 is provided with a material taking port 1a, and a waste receiving plate 7 is fixedly provided in the reaction tank body 1, the waste receiving plate 7 is located below the material taking port 1a, and the waste receiving plate 7 is used to support the falling waste, so that workers can take out the waste. It is characterized in that it includes a reaction tank body 1, a rotating mechanism 2, an airflow pipe group 3, a new material receiving plate 4, an elastic pull-down mechanism 6, a lifting and pulling mechanism 8 and a plurality of discharge net boxes 5, and the airflow pipe group 3 includes a central air pipe 3 a and gas diffusion head 3b, the bottom of the central air pipe 3a is plugged into the bottom gas port of the reaction tank body 1, the rotating mechanism 2 is fixedly installed on the reaction tank body 1, the rotating seat of the rotating mechanism 2 is fixedly connected to the central air pipe 3a, the rotating mechanism 2 can drive the central air pipe 3a to rotate, the gas diffusion head 3b is fixedly installed on the top of the central air pipe 3a, the untreated waste gas transported upward along the central air pipe 3a will be diffused along the gas diffusion head 3b, when the central air pipe 3a is driven to rotate, the gas diffusion head 3b will also be driven to rotate synchronously, so that all adsorbed particles can be adsorbed with the untreated waste gas. The new material receiving plate 4 is located below the gas diffusion head 3b, and the new material receiving plate 4 is rotatably connected to the inner wall of the reaction tank body 1, so that the new material receiving plate 4 cannot move up and down. And the new material receiving plate 4 is fixedly connected to the gas diffusion head 3b, so that when the gas diffusion head 3b rotates, it can drive the new material receiving plate 4 to rotate together. The new material receiving plate 4 is used to receive the new material, wherein both the new material and the waste material are adsorption particles, wherein the waste material is the adsorption particles that have expired, and the new material is the adsorption particles that have not expired. A plurality of discharge net boxes 5 can be vertically slidably installed on the new material receiving plate 4, the bottom of the discharge net box 5 is an open structure, and the side of the discharge net box 5 along the rotation direction of the central air pipe 3a is also an open structure, so that when the new material receiving plate 4 drives the plurality of discharge net boxes 5 to rotate, the adsorption particles at the bottom can be discharged downward along the opening of the discharge net box 5 and fall onto the waste material receiving plate 7. Multiple discharge net boxes 5 are installed on the elastic pull-down mechanism 6, which is used to provide a downward elastic pulling force to the discharge net boxes 5. The elastic pull-down mechanism 6 is fixedly installed on the lifting and pulling mechanism 8, which is used to pull the elastic pull-down mechanism 6 downward. When the elastic pull-down mechanism 6 is pulled downward, the discharge net boxes 5 will get stuck with some adsorbed particles during the descending process, resulting in difficulty in descending. Therefore, the elastic pull-down mechanism 6 is needed to compensate for the distance where the descent is difficult to avoid damage to the equipment.Among them, the central air pipe 3a is provided with an upper return air port 3a1 and a lower return air port 3a2, and the lifting and pulling mechanism 8 is fixedly provided with an upper sealing ring 8a and a lower sealing ring 8b which can move up and down together, the upper sealing ring 8a is used to seal the upper return air port 3a1, and the lower sealing ring 8b is used to seal the lower return air port 3a2, and the lifting and pulling mechanism 8 is fixedly provided with a sealing ring pushing mechanism 9 for driving the upper sealing ring 8a to move up and down, and the sealing ring pushing mechanism 9 is used to push the upper sealing ring 8a upward, so that the upper sealing ring 8a opens the seal on the upper return air port 3a1;.

[0036] like Figure 3 As shown, when switching to the adsorption process, the lifting and pulling mechanism 8 is pushed upward, and the discharge net box 5 moves upward, so that the discharge net box 5 can discharge the adsorbed particles downward during the rotation, and the upper sealing ring 8a covers the upper return air port 3a1, and the lower sealing ring 8b covers the lower return air port 3a2, so that the untreated waste gas transported upward along the central air pipe 3a can be discharged along the gas diffusion head 3b; wherein, each time the gas diffusion head 3b needs to change the exhaust position, it will drive multiple discharge net boxes 5 to rotate, and at the same time allow the adsorbed particles to be discharged downward.

[0037] When the process switches to desorption, and the waste gas after desorption only needs to be discharged along the upper return air port 3a1, the lifting and pulling mechanism 8 pulls downward, and the discharge net box 5 moves downward, so that the adsorbed particles can no longer be discharged downward, because in the process of desorption, the rotating mechanism 2 drives the central air pipe 3a to stir the adsorbed particles, so that the ventilation position changes at any time. The upper return air port 3a1 and the lower return air port 3a2 are both in an open state, but because the adsorbed particles are stored on the top of the waste receiving plate 7, which hinders the waste gas, the waste gas will only enter the central air pipe 3a along the upper return air port 3a1. In this way, when the adsorbent particles on the top of the waste receiving plate 7 need to be discarded, the desorption time of the adsorbent particles above the new material receiving plate 4 can be shortened.

[0038] like Figure 5 As shown, when switching to the desorption process, and the waste gas after desorption only needs to be discharged along the lower return air port 3a2, the lifting and pulling mechanism 8 pulls downward, the discharge net box 5 moves downward, and the lower return air port 3a2 is in an open state. The sealing ring pushing mechanism 9 pushes the upper sealing ring 8a upward to cover the upper return air port 3a1, so that the waste gas cannot be transported along the upper return air port 3a1 to the central air pipe 3a. The waste gas can only penetrate the adsorption particles on the top of the waste receiving plate 7 through a higher pressure, and then enter the central air pipe 3a.

[0039] In order to realize that the lifting and pulling mechanism 8 can simultaneously drive the elastic pulling mechanism 6, the upper sealing ring 8a and the lower sealing ring 8b to move up and down, for this purpose, Figure 4As shown, the lifting and pulling mechanism 8 includes an upper sealing ring 8a, a lower sealing ring 8b, two electro-hydraulic push rods 8d and a plurality of connecting rods 8c, wherein the plurality of connecting rods 8c are fitted with the inner wall of the reaction tank body 1, and the top of the connecting rod 8c is fixedly connected to the top plate 8f, and the bottom of the connecting rod 8c is fixedly connected to the bottom plate 8e, and the lower sealing ring 8b is located in the middle of the bottom plate 8e, and the sealing ring pushing mechanism 9 is fixedly installed on the connecting rod 8c, and the upper sealing ring 8a is fixedly installed on the pushing end of the sealing ring pushing mechanism 9, and the elastic pull-down mechanism 6 is fixedly installed on the top plate 8f. That is, when the connecting rod 8c moves upward, the lower sealing ring 8b is driven to move upward through the bottom plate 8e, and the upper sealing ring 8a is driven to move upward through the sealing ring pushing mechanism 9, and the elastic pull-down mechanism 6 can be driven to move upward through the top plate 8f. On the contrary, the elastic pull-down mechanism 6, the upper sealing ring 8a and the lower sealing ring 8b can be driven to move downward. The waste receiving plate 7 is provided with an avoidance hole for the lifting and pulling mechanism 8 to slide through, and the avoidance hole can provide a fulcrum for the lifting and pulling mechanism 8 to prevent the lifting and pulling mechanism 8 from bending.

[0040] In order to realize that when the discharge net box 5 and the adsorption particles are engaged, the elastic pull-down mechanism 6 can play a buffering role. Figure 6 and Figure 7 As shown, the elastic pull-down mechanism 6 includes a plurality of U-shaped arc plates 6a, which are fitted together to form an annular structure. The inner edge top of the U-shaped arc plate 6a fits with the top plate 8f. When the top plate 8f moves upward, it can lift the plurality of U-shaped arc plates 6a to move vertically upward. Two slide posts 6b and a spring 1 6c are provided on each U-shaped arc plate 6a. The slide post 6b can be installed on the U-shaped arc plate 6a in a vertically sliding manner. A conical block is provided on the top of the slide post 6b. The spring 1 6c is used to provide a vertically upward elastic force to the conical block, and the top of the conical block contacts the bottom of the top plate 8f. When the top plate 8f is pulled downward, if the discharging net box 5 encounters an obstacle of adsorbed particles, the top plate 8f will push the slide post 6b downward to compress the spring 1 6c to avoid equipment failure. Figure 6 The position of the discharging net box 5 shown is the state where the lifting and pulling mechanism 8 is not pushed upward. Among them, the U-shaped arc plate 6a adopts a U-shaped structure and also has the function of guiding and limiting the multiple U-shaped arc plates 6a to prevent the multiple U-shaped arc plates 6a from separating from each other.

[0041] In order to enable the sealing ring lifting mechanism 9 to push the upper sealing ring 8a upward to move, for this purpose, Figure 4 and Figure 8As shown, horizontally arranged slide plates 8h are fixedly arranged on both sides of the upper sealing ring 8a, and the slide plates 8h can be vertically slidably installed on the connecting rod 8c. The sealing ring lifting mechanism 9 includes two synchronous lifters, and the two synchronous lifters are respectively below the two, and each synchronous lifter includes an electric push rod 9a, a horizontal slide column 9b, a vertical slide column 9c, a hinge rod 9d and an elastic gate 9e. The vertical slide column 9c is slidably connected to the lower sealing ring 8b, and a sliding hole for the vertical slide column 9c to pass through is opened on the lower sealing ring 8b. The horizontal slide column 9b is connected to the connecting rod 8c. The connecting rod 8c is slidably connected, and a sliding hole is provided on the connecting rod 8c for the horizontal sliding column 9b to pass through. The electric push rod 9a is fixedly installed on the connecting rod 8c, and the output end of the electric push rod 9a is fixedly connected to the horizontal sliding column 9b. One end of the hinged rod 9d is hinged to the vertical sliding column 9c, and the other end of the hinged rod 9d is hinged to the horizontal sliding column 9b. The elastic gate 9e is fixedly installed on the lower sealing ring 8b, and the elastic gate 9e blocks the top of the vertical sliding column 9c. When it is necessary to push the sliding plate 8h upward, the elastic gate 9e blocks the vertical sliding column 9c. By controlling the electric push rod 9a to work, the vertical sliding column 9c will push the hinged rod 9d to move through the horizontal sliding column 9b, so that the hinged rod 9d can push the vertical sliding column 9c to move vertically upward, and the elastic gate 9e blocks the top of the vertical sliding column 9c, so that the vertical sliding column 9c drives the upper sealing ring 8a to move vertically upward through the slide plate 8h, that is, the upper sealing ring 8a seals the upper return air port 3a1.

[0042] During long-term use, the powder produced by the adsorbent will be stuck in the holes of the discharge net box 5, which makes it difficult for the waste gas to pass through the discharge net box 5 during desorption. Figure 4 and Figure 8 As shown, when the vertical slide column 9c needs to knock the U-shaped arc plate 6a, the elastic gate 9e opens, allowing the slide plate 8h to slide downward, and at this time, the horizontal slide column 9b can be reciprocated to allow the vertical slide column 9c to knock the U-shaped arc plate 6a, and the U-shaped arc plate 6a will vibrate the discharge net box 5 through vibration conduction, so that the powder in the hole of the discharge net box 5 can be discharged downward. And multiple discharge net boxes 5 are in a rotating state during this process, that is, they can knock multiple U-shaped arc plates 6a.

[0043] The elastic gate 9e is relatively close to the heating pipe 10, which makes it impossible for the elastic gate 9e to use electrical components, otherwise it will be often damaged. Fig. 9As shown, the elastic gate 9e includes two elastic connectors, which are respectively located on both sides of the vertical sliding column 9c. Each elastic connector includes a trapezoidal block 9e1, a spring 9e2, a guide seat 9e3, a guide column 9e4 and a limit plate 9e5. The guide column 9e4 is fixedly mounted on the lower sealing ring 8b, and the guide seat 9e3 can be horizontally slidably mounted on the guide column 9e4. The trapezoidal block 9e1 is fixedly mounted on one end of the guide seat 9e3, and the limit plate 9e5 is fixedly mounted on the other end of the guide seat 9e3. The inclined surface of the trapezoidal block 9e1 is located above the vertical sliding column 9c, and the guide seat 9e3 is used to provide an elastic force for the trapezoidal block 9e1 to approach the vertical sliding column 9c. When the vertical sliding column 9c is pushed upward, the two trapezoidal blocks 9e1 block the vertical sliding column 9c, so that the vertical sliding column 9c can drive the slide plate 8h to move upward. When encountering Fig. 9 In the state shown, as the vertical slide column 9c continues to be pushed upward, since the trapezoidal block 9e1 cannot continue to move upward, the vertical slide column 9c will push the two trapezoidal blocks 9e1 to both sides, and finally the top of the vertical slide column 9c passes through the two trapezoidal blocks 9e1, and then the slide plate 8h drives the sealing ring lifting mechanism 9 to slide downward through gravity, that is, the elastic gate 9e can block or open the vertical slide column 9c without using electrical components.

[0044] like Fig.10 As shown, a blocking bottom plate 8s and two side baffles 8j are fixedly arranged on the connecting rod 8c, the two sides of the slide plate 8h are in contact with the inner sides of the two side baffles 8j, and the blocking bottom plate 8s is located between the two side baffles 8j. When the vertical slide column 9c is separated from the elastic gate 9e, the slide plate 8h can slide vertically downward between the two side baffles 8j, and the limit position of the downward sliding is blocked by the blocking bottom plate 8s.

[0045] like Fig.11 As shown, the gas diffusion head 3b includes a connection seat 3b1, a fixing ring 3b3 and a plurality of gas distribution pipes 3b2, the connection seat 3b1 is fixedly mounted on the top of the central gas pipe 3a, the plurality of gas distribution pipes 3b2 are connected to the inside of the central gas pipe 3a through the connection seat 3b1, the fixing ring 3b3 is fixedly mounted on the outer edge of the plurality of gas distribution pipes 3b2, and the bottom of the fixing ring 3b3 is in contact with the top of the new material receiving plate 4. The central gas pipe 3a drives the connection seat 3b1 to rotate, so that the connection seat 3b1 can drive the plurality of gas distribution pipes 3b2 to rotate, so that the exhaust gas discharged upward can be evenly dispersed.

[0046] During use, when switching to the adsorption process, the lifting and pulling mechanism 8 is pushed upward, and the discharge net box 5 moves upward, so that the discharge net box 5 can discharge the adsorbed particles downward during the rotation process, and the adsorbent particles finally fall on the waste receiving plate 7. In addition, the upper sealing ring 8a covers the upper return air port 3a1, and the lower sealing ring 8b covers the lower return air port 3a2, so that the untreated waste gas transported upward along the central air pipe 3a can be discharged along the gas diffusion head 3b.

[0047] When the process is switched to desorption, and the waste gas after desorption only needs to be discharged along the upper return air port 3a1, the lifting and pulling mechanism 8 is pulled downward, and the discharge net box 5 moves downward, so that the adsorbed particles can no longer be discharged downward. The upper return air port 3a1 and the lower return air port 3a2 are both in an open state, but because the adsorbed particles are stored on the top of the waste receiving plate 7, the waste gas is blocked, so that the waste gas can only enter the central air pipe 3a along the upper return air port 3a1.

[0048] When switching to the desorption process, and the waste gas after desorption only needs to be discharged along the lower return air port 3a2, the lifting and pulling mechanism 8 is pulled downward, and the discharge net box 5 moves downward, so that the upper return air port 3a1 and the lower return air port 3a2 are both in an open state, and then the upper sealing ring 8a is pushed upward by the sealing ring pushing mechanism 9 to cover the upper return air port 3a1, so that the waste gas cannot be transported along the upper return air port 3a1 to the central air pipe 3a. The waste gas can only penetrate the adsorption particles on the top of the waste receiving plate 7 through a higher pressure, and then enter the central air pipe 3a.

[0049] By switching the above three states, the exhaust gas in the desorption process can be controlled to flow into the central air pipe 3a along the upper return air port 3a1 or flow into the central air pipe 3a along the lower return air port 3a2, thereby realizing the exhaust gas flow direction control in the desorption process and saving the desorption time and nitrogen consumption.

[0050] And when the discharge net box 5 is blocked by adsorbed particles, it can be buffered by the elastic pull-down mechanism 6 to avoid equipment failure. And due to the existence of the elastic pull-down mechanism 6, the sealing ring lifting mechanism 9 can vibrate the discharge net box 5 by knocking, and combined with the airflow tube group 3, it can drive multiple discharge net boxes 5 to rotate, so as to clean the air holes on multiple discharge net boxes 5 and avoid blockage. And the sealing ring lifting mechanism 9 can also play the role of pushing the upper sealing ring 8a upward to seal the upper return air port 3a1. And the elastic gate 9e does not need to be electrically controlled, but is automatically controlled to open by mechanical means, and only needs to control the working distance of the electric push rod 9a.

[0051] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
