Abstract
Description
Technical Field
[0001] This application relates to the technical field of waste gas treatment, and particularly to an organic waste gas adsorption and desorption treatment device. Background Art
[0002] With the rapid development of China's economy, there are more and more polluting industries involving organic waste gases (VOCs). At present, one of the mainstream technologies for industrial VOCs treatment is granular carbon adsorption and desorption technology. The principle of granular carbon adsorption for treating organic waste gases is mainly to utilize the adsorption performance of granular carbon to adsorb organic pollutants in the waste gas on the surface of the granular carbon, so as to achieve the purpose of purifying the waste gas, and then utilize the high-temperature desorption performance of granular carbon to separate the pollutants on the surface of the granular carbon at high temperature.
[0003] Since the adsorption and desorption of granular carbon are two reverse processes, adsorption is to adsorb organic waste gas in the microporous structure of granular carbon, and desorption is to separate the organic waste gas in the microporous structure. The two processes cannot be carried out simultaneously. Conventional granular carbon adsorption tanks are of a fixed-bed structure. During long-term adsorption use, a large amount of organic pollutants are adsorbed on the surface of the granular carbon. Eventually, the granular carbon reaches adsorption saturation. At this time, it is necessary to perform high-temperature desorption on the granular carbon. Only after high-temperature desorption of the granular carbon can it continue to adsorb organic waste gas. However, during the high-temperature desorption process of the granular carbon, it cannot adsorb, that is, the adsorption and desorption operations cannot be carried out simultaneously. At this time, it will cause the customer's factory to shut down, resulting in discontinuous production, reducing work efficiency. In addition, during the processes of cooling adsorption and heating desorption for the fixed-bed structure, only the overall granular carbon tank can be heated and cooled, resulting in heat waste, large energy consumption, increased costs, and reduced work efficiency. Summary of the Utility Model
[0004] This application provides an organic waste gas adsorption and desorption treatment device, which can perform desorption while continuously adsorbing granular carbon, enabling customers to produce continuously. At the same time, part of the treatment device can be selected for adsorption and part for desorption according to requirements, and a small amount of gas after selection can be condensed and desorbed according to requirements to achieve the same recovery effect as the overall fixed-bed system, reducing costs and improving work efficiency.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will elaborate on each embodiment of the present application with reference to the accompanying drawings. However, those of ordinary skill in the art can understand that in each embodiment of the present application, many technical details are presented to help readers better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can still be implemented. The division of the following embodiments is for convenience of description and should not constitute any limitation on the specific implementation manner of the present application. The various embodiments can be combined with each other and cross-referenced on the premise of not being contradictory.
[0025] The embodiments of the present application provide an organic waste gas adsorption and desorption treatment device. Please refer to Figure 1 , Figure 2 As shown, it includes a rotating wheel 1, a first sector seal 3, and a second sector seal 4. The outer shape of the rotating wheel 1 is a cylinder, and the rotating wheel 1 is divided into a number of equal-sized and mutually independent sector cavities 11 around its center. Adsorbing materials are filled in each sector cavity 11. One side of the rotating wheel 1 is the waste gas inlet side, and the opposite side is the waste gas outlet side. Two first sector seals 3 are arranged oppositely on both sides of the rotating wheel 1. The first sector seal 3 is the same size as the sector cavity 11, and the first sector seal 3 can move closer to or away from the sector cavity 11. When each time the rotating wheel 1 rotates one sector cavity 11 corresponding to the first sector seal 3, the two first sector seals 3 on both sides move closer to each other simultaneously to press both sides of the sector cavity 11 to form a high-temperature desorption channel for desorbing the organic waste gas. The second sector seal 4 is adjacent to the first sector seal 3. Two second sector seals 4 are also arranged oppositely on both sides of the rotating wheel 1. The second sector seal 4 is the same size as the sector cavity 11, and the second sector seal 4 can move closer to or away from the sector cavity 11. When each time the sector cavity 11 after desorption treatment of the rotating wheel 1 corresponds to the second sector seal 4, the two second sector seals 4 on both sides also move closer to each other simultaneously to press both sides of the sector cavity 11 to form a low-temperature cooling channel for cooling the adsorbing materials. Of course, the organic waste gas adsorption and desorption treatment device as a whole is in a sealed device, and only the interfaces for the front and rear waste gas inlet and outlet need to be reserved for this device.
[0026] In this embodiment, it should be noted that a central shaft 12 is provided through the center of the rotating wheel 1 and along the axial direction of the rotating wheel 1. A bracket 2 is further provided outside the rotating wheel 1. Both ends of the central shaft 12 are fixed on the bracket 2 to support the rotating wheel 1, and the rotating wheel 1 can rotate around the central shaft 12. The rotating wheel 1 is divided into a number of equal-sized and mutually independent fan-shaped cavities 11 around its center. In one example, the rotating wheel 1 can be radially divided into 16 equal parts to obtain 16 fan-shaped cavities 11. Of course, the specific zoning of the rotating wheel 1 can also be determined according to the concentration of the exhaust gas produced and the air volume. For example, different equal parts such as 8 - 14 can also be selected. Similarly, the positions of two of the fan-shaped cavities 11 are taken as the desorption area and the cooling area, and the other fan-shaped cavities 11 are used as adsorption areas to adsorb and filter the organic waste gas simultaneously. Thus, it can perfectly solve the problem that in the desorption treatment of the fixed bed, only the whole carbon canister can be subjected to adsorption and desorption treatment. For example, if the fixed bed is 1 adsorption, 1 desorption, and 1 cooling, more than 3 fixed tanks are required, and the air volume is the same. For utilities, the demand for condensed circulating water is very large. However, the current treatment device can divide the rotating wheel into multiple blocks according to needs, and determine the specific zoning of the rotating wheel 1 according to the concentration of the exhaust gas produced and the air volume, which can reduce the initial consumption of utilities and thus reduce costs. Moreover, this treatment device can also be flexibly zoned according to needs to perform adsorption and desorption simultaneously, avoiding the adsorption form of the fixed bed that cannot achieve continuous operation and can only adsorb or desorb separately, so as to achieve the purpose of continuous adsorption and desorption.
[0027] In addition, such as Figure 2 and Figure 3As shown, the sector cavity 11 is provided with a cavity, and an adsorption material is filled in the cavity. The adsorption material may include two layers of molecular sieves and a granular carbon layer located between the two layers of molecular sieves. Specifically, the granular carbon layer may be set as an activated carbon layer with a thickness of 1.5 meters. Hollow holes communicating with the inside of the cavity are respectively provided on both sides of the sector cavity 11. The organic waste gas enters the inside of the sector cavity 11 through the hollow holes, so that the granular carbon layer filled in the sector cavity 11 adsorbs the organic waste gas, and the filtered gas then flows out from the other side of the sector cavity 11. A loading port 111 communicating with the cavity is also provided on the curved surface of the sector cavity 11. The loading port 111 can realize the loading and discharging of the adsorption material, ensuring the normal loading and replacement of the adsorption material. In this embodiment, the adsorption material is set as a composite structure of molecular sieve and granular carbon layer. The molecular sieve at the front provides the functions of sealing and waste gas adsorption, the granular carbon layer in the middle adsorbs the waste gas, and the molecular sieve at the end recovers and collects the residual waste gas, reducing the influence of the adsorption residue of the overall granular carbon layer. Of course, in other embodiments, both the front and rear sides of the sector cavity 11 are open, molecular sieves are directly provided at the open positions, and the granular carbon layer is provided inside the sector cavity 11, also forming a composite structure of molecular sieve, granular carbon layer and molecular sieve. How to specifically set it is not specifically limited in this embodiment.
[0028] As Figure 1 shown, the treatment device further includes a driving mechanism 5. The driving mechanism 5 can drive the runner 1 to rotate pulsatingly according to the number of the sector cavities 11, so that the sector cavity 11 can simultaneously enter the first sector seal 3 and the second sector seal 4 cyclically while adsorbing the organic waste gas, achieving the effect of continuous adsorption and desorption.
[0029] Specifically, in one example, the driving mechanism 5 includes a rack 51 and a motor 52. The rack 51 is installed in a full circle along the outer circumference of the runner 1, and the motor 52 is in meshing transmission with the rack 51 through a gear. The motor 52 is started, so that the motor 52 drives the rack 51 to rotate pulsatingly through the gear. For example, for a runner 1 divided into 16 equal parts, the motor 52 drives the runner 1 to pulsate and rotate 1 / 16 each time, so that each sector cavity 11 can enter the first sector seal 3 and the second sector seal 4 cyclically to achieve the effect of continuous adsorption and desorption.
[0030] In this embodiment, it should also be noted that as Figure 1 and Figure 2As shown in the figure, on both sides of the rotating wheel 1, a first sector seal 3 is arranged at a position corresponding to one of a number of equally divided sector cavities 11. The first sector seal 3 has the same size and shape as the sector cavity 11. The first sector seal 3 can approach or move away from the corresponding sector cavity 11. When the first sector seal 3 approaches the corresponding sector cavity 11 and presses it tightly, the first sector seal 3 and the corresponding sector cavity 11 form a high-temperature desorption channel to desorb the organic waste gas.
[0031] Specifically, the first sector seals 3 are arranged on both sides of the rotating wheel 1. In other words, two first sector seals 3 are provided. The two first sector seals 3 are oppositely arranged on both sides of the rotating wheel 1 and correspond to the size and position of one of the sector cavities 11. The first sector seal 3 is a cavity with a hollow interior. The first sector seal 3 is provided with an opening on one side for pressing and fitting the sector cavity 11, and the opposite side is hermetically sealed. The first sector seal 3 is also provided with a desorption connection port 31 for introducing or discharging desorption gas on its sealed side. It can be understood that when the desorption connection port 31 on one of the first sector seals 3 is used for introducing desorption gas, the desorption connection port 31 on the remaining first sector seal 3 is used for discharging desorption gas. Therefore, when the two first sector seals 3 approach each other and their respective opening sides press the sector cavity 11 tightly, they are connected to the inside of the sector cavity 11 to form a desorption seal cavity. The external intake pipe is connected to the desorption connection port 31 through a flange or a metal hose for soft connection, so as to facilitate the forward and backward movement of the first sector seal 3 and introduce high-temperature desorption gas. Generally, nitrogen is used here. Nitrogen enters one side of the first sector seal 3 through the desorption connection port 31 and then flows to the sector cavity 11, where it undergoes a high-temperature reaction with the organic waste gas adsorbed by the granular carbon layer in the sector cavity 11 to achieve the desorption treatment of the organic waste gas. After the desorption treatment, it flows out from the other side of the first sector seal 3. As Figure 4 shown in the figure, the flow direction of the high-temperature desorption gas is as shown by b, and the flow direction of the organic waste gas is as shown by a.
[0032] At the same time, on both sides of the rotating wheel 1, a second sector seal 4 is arranged at a position corresponding to the sector cavity 11 and adjacent to the first sector seal 3. Similarly, the second sector seal 4 can approach or move away from the corresponding sector cavity 11. When the second sector seal 4 approaches the corresponding sector cavity 11 and presses it tightly, the second sector seal 4 and the corresponding sector cavity 11 form a low-temperature cooling channel to cool the adsorption material.
[0033] Specifically, the second sector seal 4 is provided on both sides of the runner 1. In other words, there are two second sector seals 4, which are oppositely arranged on both sides of the runner 1 and correspond to the size and position of one of the sector cavities 11. The second sector seal 4 is a cavity with a hollow interior. The second sector seal 4 is used to press and fit one side of the sector cavity 11 with an opening, and the opposite side is sealed. Moreover, a cooling connection port 41 for introducing or discharging cooling gas is provided on the sealed side of the second sector seal 4. It can be understood that when the cooling connection port 41 on one of the second sector seals 4 is used for introducing cooling gas, the cooling connection port 41 on the remaining second sector seal 4 is used for discharging cooling gas. Therefore, when the two second sector seals 4 approach each other until their respective opening sides press against the sector cavity 11, they are connected to the inside of the sector cavity 11 to form a cooling seal cavity. The external intake pipe is flexibly connected to the cooling connection port 41 through a flange or connected using a metal hose, so as to facilitate the forward and backward movement of the second sector seal 4 and introduce low-temperature cooling gas. The low-temperature cooling gas enters one side of the second sector seal 4 through the cooling connection port 41 and then flows to the sector cavity 11, where it is cooled at a low temperature with the organic waste gas desorbed at a high temperature inside the sector cavity 11, realizing the cooling treatment of the organic waste gas. After the cooling treatment, it flows out from the other side of the second sector seal 4. As Figure 4 shown, the flow direction of the low-temperature cooling gas is as shown by c here.
[0034] In this embodiment, the organic waste gas is adsorbed through the sector cavity 11. Then, as each sector cavity 11 passes through the first sector seal 3, the adsorbed organic waste gas is subjected to high-temperature desorption treatment. When passing through the second sector seal 4, the waste gas after the high-temperature desorption treatment is subjected to low-temperature cooling treatment. By circulating in this way, the purpose of continuous adsorption and desorption is achieved, effectively avoiding the energy waste caused by directly heating and using the whole system in the form of a fixed bed, with overall desorption for temperature rise and condensation for temperature drop. According to this treatment device, through the adjacent high-temperature desorption and low-temperature cooling channels, the distance between the adjacent pipes is smaller, which not only enables heat exchange but also reduces energy loss, lowers costs, and improves work efficiency.
[0035] In addition, as Figure 2 shown, sealing gaskets 6 are provided on the sealing surfaces of the first sector seal 3 and the second sector seal 4 that are in contact with the sector cavity 11, so as to further ensure that when the first sector seal 3 and the second sector seal 4 press against the corresponding sector cavity 11, a sealed state is formed to prevent gas leakage.
[0036] In one example, the first sector seal 3 and the second sector seal 4 are respectively driven linearly by cylinders. The cylinders drive the first sector seal 3 or the second sector seal 4 arranged on both sides of the runner 1 to move closer to or away from each other, so as to facilitate clamping or loosening the corresponding sector cavity 11 as required.
[0037] In an implementable manner, the sides of the first sector seal 3 and the second sector seal 4 on the same side are connected and controlled to move simultaneously by cylinders. Then, when it is necessary to desorb and cool the adsorption material in the sector cavity 11, the first sector seal 3 and the second sector seal 4 on both sides are driven by the cylinders to move closer together as a whole, and then the desorption area and the cooling area are simultaneously pressed. For example, side plates can be respectively installed on the sides of the first sector seal 3 and the second sector seal 4, cylinders are respectively arranged on the sides of the first sector seal 3 and the second sector seal 4, and the cylinders act simultaneously. The cylinder bodies of the cylinders are fixed, and the output shafts of the respective cylinders are respectively connected to the side plates of the first sector seal 3 and the second sector seal 4, so as to control the overall forward and backward movement of the first sector seal 3 and the second sector seal 4 through the output shafts of the cylinders. There is no specific limitation on how to install the cylinders in this embodiment.
[0038] It should be noted that in the above embodiments, for the structure of linear drive using cylinders, in addition to the structures described in the embodiments, other structures can also be used to achieve it. The present application does not list them one by one. As long as it is within the above-mentioned spirit and principle of the embodiments of the present application, it belongs to the protection scope of the present application.
[0039] Implementation principle of this embodiment: The runner 1 rotates around the central axis 12. The runner 1 is equally divided into several fan-shaped cavities 11, and the fan-shaped cavities 11 are filled with a granular carbon layer. The organic waste gas passes through the granular carbon layer inside the runner 1 from one side of the runner 1 and blows to the other side, thereby filtering the organic waste gas. Each time the runner 1 rotates to the fan-shaped cavity 11 corresponding to the first fan-shaped seal 3, this fan-shaped cavity 11 is defined as the desorption zone. When it rotates to the fan-shaped cavity 11 corresponding to the second fan-shaped seal 4, this fan-shaped cavity 11 is positioned as the cooling zone. During desorption and cooling, the cylinder drives the first fan-shaped seal 3 and the second fan-shaped seal 4 on both sides to simultaneously press the desorption zone and the cooling zone. The high-temperature desorption gas flows through b to desorb the activated carbon in the desorption zone, enabling the adsorption-saturated activated carbon to regain its adsorption capacity. At the same time, the low-temperature cooling gas flows according to c to cool down the activated carbon in the cooling zone after high-temperature desorption, enabling the activated carbon to adsorb waste gas again. After the desorption of the activated carbon in the desorption zone is completed and the cooling of the activated carbon in the cooling zone is completed, during the pulsating zone change process, the cylinder drives the first fan-shaped seal 3 and the second fan-shaped seal 4 to simultaneously move away from the desorption zone and the cooling zone. At this time, the runner 1 pulsates and rotates in the rotation direction. When desorbing and cooling again, the cylinder drives the first fan-shaped seal 3 and the second fan-shaped seal 4 on both sides to simultaneously press the desorption zone and the cooling zone again, ensuring the overall seal of the desorption and cooling channels. By circulating in this way, there is no need to stop the equipment for desorption after the granular carbon is adsorption-saturated. Users can use this equipment for continuous production, improving production efficiency and bringing greater economic benefits to the enterprise.
[0040] It should be understood that the above specific implementation manners of the present application are only used for exemplary illustration or explanation of the principle of the present application, and do not constitute a limitation to the present application. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present application shall be included within the protection scope of the present application. In addition, the appended claims of the present application are intended to cover all changes and modification examples falling within the scope and boundary of the appended claims, or equivalent forms of such scope and boundary.
