Abstract
Description
Technical Field
[0001] This utility model relates to the field of exhaust gas treatment technology, specifically to a device for harmless treatment of fluorobenzene thermal reaction exhaust gas. Background Technology
[0002] The exhaust gas from the thermal reaction of fluorobenzene typically contains toxic and harmful components such as fluorobenzene, halogenated hydrocarbons, and benzene compounds. Direct emission of these substances can harm the environment and human health. Separation of pollutants in the exhaust gas is achieved by utilizing the physical properties (such as boiling point, adsorption capacity, particle size, and volatility) of the pollutants, eliminating the need for chemical reagents and avoiding secondary pollution. Lowering the exhaust gas temperature prevents subsequent adsorbent failure due to high temperatures and simultaneously removes particulate matter, preventing equipment blockage. For the harmless treatment of this type of exhaust gas, the treatment device primarily removes pollutants through treatment processes, offering advantages such as simple operation, no secondary pollution, and resource recovery.
[0003] However, in the process of using common exhaust gas harmless treatment, the soot in the exhaust gas is easily adsorbed into the conveying pipeline. After long-term transportation, more dust will stick to it, which can easily affect the treatment effect. In addition, when using activated carbon to adsorb and treat exhaust gas, if the utilization rate of the contact area between exhaust gases is small, it will also affect the treatment effect. Therefore, there is still room for further improvement.
[0004] Therefore, we propose a harmless treatment device for the tail gas from the thermal reaction of fluorobenzene in order to solve the problems mentioned above. Utility Model Content
[0005] The purpose of this invention is to provide a harmless treatment device for the thermal reaction tail gas of fluorobenzene, in order to solve the common problems mentioned in the background art. During the use of the tail gas harmless treatment, the dust in the tail gas is easily adsorbed into the conveying pipeline. After long-term transportation, more dust will adhere, which will easily affect the treatment effect. In addition, when using activated carbon to adsorb and treat the tail gas, if the utilization rate of the contact area between the tail gas and the tail gas is small, it will also affect the treatment effect. Therefore, there is still room for further improvement.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for the harmless treatment of fluorobenzene thermal reaction tail gas, comprising:
[0007] A pretreatment tank, wherein an inlet pipe is provided on the upper side of the pretreatment tank and a drain pipe is provided on the front side of the pretreatment tank;
[0008] Also includes:
[0009] The pretreatment box is equipped with a cooling mechanism for convenient exhaust gas treatment, and a serpentine conveying pipe runs through the interior of the pretreatment box, with a flange on the left side of the serpentine conveying pipe.
[0010] An adsorption box is provided inside which an adsorption mechanism is installed to absorb harmful substances in the exhaust gas, and the adsorption box is fixedly connected to a serpentine conveying pipe.
[0011] Preferably, the lower side of the serpentine conveying pipe is provided with a slag discharge port, and the slag discharge port is threadedly connected to the sealing cap.
[0012] Preferably, the cooling mechanism is composed of a serpentine conveying pipe, a servo motor, a rotating shaft, a hollow column, a spring, a connecting column, and a striking ball. The servo motor is located on the left side of the pretreatment box, and the output shaft of the servo motor is fixedly connected to the rotating shaft, and the rotating shaft is rotatably connected to the pretreatment box.
[0013] Preferably, the side of the rotating shaft is provided with hollow columns, which are arranged in an array, and springs are provided inside the hollow columns.
[0014] Preferably, the spring is tightly fitted to the connecting post, the connecting post is slidably connected to the hollow post, and the connecting post is fixedly connected to the striking ball.
[0015] Preferably, the adsorption mechanism is composed of an adsorption box, a box cover, an exhaust port, a connecting groove, a partition grid, activated carbon particles, and an addition port. The front of the adsorption box is rotatably connected to the box cover, the right side of the adsorption box is provided with an exhaust port, and the upper side of the adsorption box is provided with an addition port.
[0016] Preferably, a connecting groove is provided on the lower inner side of the adsorption box, and the connecting groove is symmetrical about the vertical central axis of the adsorption box. The connecting groove is slidably connected to the partition grid plate, and activated carbon particles are provided on the right side of the partition grid plate and in the middle of the adsorption box.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: In this fluorobenzene thermal reaction tail gas harmless treatment device, the rotation of the hollow column allows the striking ball to periodically contact the side of the serpentine conveying pipe, thereby facilitating the shedding of dust adsorbed inside the serpentine conveying pipe and facilitating the transfer of heat from the tail gas transported in the serpentine conveying pipe to the liquid in the pretreatment tank, thus facilitating the cooling treatment of the tail gas. When the connecting column with the striking ball contacts the serpentine conveying pipe, the striking ball causes the connecting column to slide inside the hollow column. At this time, the spring will undergo elastic deformation, which can not only remove dust but also prevent damage to the serpentine conveying pipe. The partition grid can divide the interior of the adsorption box into two parts, which can increase the contact area between the tail gas and the activated carbon particles, thereby enhancing the tail gas absorption and treatment effect.
[0018] 1. It is equipped with a serpentine conveying pipe, a slag discharge port and a sealing cover. The serpentine conveying pipe runs through the pretreatment box and facilitates the transport of exhaust gas. The slag discharge port is located on the lower side of the serpentine conveying pipe and is threadedly connected to the sealing cover. When the sealing cover is opened, the dust that has been knocked down will be discharged from the slag discharge port, thereby enhancing the heat transfer during the transport of exhaust gas, facilitating cooling treatment, and helping the activated carbon particles to absorb harmful particles in the exhaust gas.
[0019] 2. Equipped with a rotating shaft, hollow column, and connecting column, the rotating shaft rotates when the servo motor is started. This rotation causes the hollow column to rotate, which in turn rotates the connecting column, allowing the striking ball to periodically contact the side of the serpentine conveying tube. This facilitates the removal of dust adsorbed inside the serpentine conveying tube and the transfer of heat from the exhaust gas transported in the serpentine conveying tube to the liquid in the pretreatment box, thus facilitating the cooling of the exhaust gas.
[0020] 3. It is equipped with a hollow column, a spring and a connecting column. The hollow column is equipped with a spring, and the spring supports the connecting column. When the connecting column and the striking ball come into contact with the serpentine conveying pipe, the striking ball will cause the connecting column to slide inside the hollow column. At this time, the spring will undergo elastic deformation, so that the serpentine conveying pipe can not only remove dust during the dust removal process, but also prevent damage to the serpentine conveying pipe.
[0021] 4. It is equipped with an adsorption box, a connecting groove, and a partition grid. The adsorption box has a connecting groove inside, and a partition grid is slidably connected inside the connecting groove. The partition grid can divide the interior of the adsorption box into two parts, which can increase the contact area between the exhaust gas and the activated carbon particles, thereby enhancing the exhaust gas absorption and treatment effect.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-6 As shown, this utility model provides a technical solution: a harmless treatment device for the tail gas of fluorobenzene thermal reaction, comprising: a pretreatment box 1, a serpentine conveying pipe 2, a slag discharge port 3, a sealing cover 4, a servo motor 5, a rotating shaft 6, a hollow column 7, a spring 8, a connecting column 9, a striking ball 10, a liquid inlet pipe 11, a liquid outlet pipe 12, an adsorption box 13, a box cover 14, an exhaust port 15, a connecting groove 16, a partition grid plate 17, activated carbon particles 18, and an addition port 19.
[0031] In existing exhaust gas harmless treatment processes, dust in the exhaust gas is easily adsorbed into the conveying pipeline during the treatment process. After long-term transportation, more dust will adhere, which can affect the treatment effect. Furthermore, when using activated carbon to adsorb and treat exhaust gas, if the utilization rate of the contact area between exhaust gases is small, it will also affect the treatment effect. Therefore, there is still room for further improvement.
[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the serpentine conveying pipe 2 is serpentine in shape and passes through the pretreatment box 1. This increases the contact area between the serpentine conveying pipe 2 and the liquid in the pretreatment box 1, facilitating the transfer of heat from the exhaust gas conveyed in the serpentine conveying pipe 2 to the liquid in the pretreatment box 1. A slag discharge port 3 is provided on the lower side of the serpentine conveying pipe 2, and the slag discharge port 3 is threadedly connected to the sealing cover 4. The slag discharge port 3 is located on the lower side of the pretreatment box 1, which facilitates the cleaning of dust that falls into the serpentine conveying pipe 2. After the sealing cover 4 is opened, the dust that has been knocked down will be discharged from the slag discharge port 3, thereby enhancing the heat transfer during exhaust gas conveying, facilitating cooling treatment, and further helping the activated carbon particles 18 to absorb harmful particles in the exhaust gas.
[0033] like Figure 2 and Figure 4 As shown, the rotating shaft 6 is rotatably connected to the inner side of the pretreatment box 1, and the rotating shaft 6 is fixedly connected to the output shaft of the servo motor 5. When the servo motor 5 is started, the servo motor 5 will cause the rotating shaft 6 to rotate. At this time, the rotating shaft 6 will rotate the hollow column 7. Since the hollow column 7 is slidably connected to the connecting column 9, it will rotate the connecting column 9, causing the striking ball 10 on the outside of the connecting column 9 to periodically contact the side of the serpentine conveying pipe 2. When the connecting column 9 and the striking ball 10 contact the serpentine conveying pipe 2, the striking ball 10 will cause the connecting column 9 to slide inside the hollow column 7. At this time, the spring 8 will undergo elastic deformation, so that the serpentine conveying pipe 2 can not only remove dust during the dust removal process, but also prevent damage to the serpentine conveying pipe 2. Due to the impact of the striking ball 10, the dust adsorbed on the inner wall of the serpentine conveying pipe 2 can be easily removed, and the heat in the exhaust gas transported in the serpentine conveying pipe 2 can be transferred to the liquid in the pretreatment box 1 through the serpentine conveying pipe 2, which can facilitate the cooling treatment of the exhaust gas.
[0034] In addition, when the striking ball 10 is disconnected from the serpentine conveying pipe 2, the spring 8 will restore its elastic deformation and push the connecting column 9 to slide inside the hollow column 7, making it convenient for the striking ball 10 to strike the serpentine conveying pipe 2 next time. Furthermore, an inlet pipe 11 is provided on the upper side of the pretreatment box 1, and a drain pipe 12 is provided on the lower front side of the pretreatment box 1, which facilitates the circulation of the cooled liquid inside and outside the pretreatment box 1, thereby achieving a good treatment effect.
[0035] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the right side of the serpentine conveying pipe 2 is fixedly connected to the adsorption box 13, and the front side of the adsorption box 13 is rotatably connected to the box cover 14. In use, first open the cover on the upper side of the adding port 19, then add the activated carbon particles 18 into the inside of the adsorption box 13, and then close the cover. When the exhaust gas is delivered into the adsorption box 13, it will first come into contact with the partition grid 17, and then be discharged from the exhaust port 15 after being adsorbed by the activated carbon particles 18.
[0036] When it is necessary to replace the separator 17 or the activated carbon particles 18, open the latch connecting the cover 14 and the adsorption box 13 to open the cover 14. At this time, the activated carbon particles 18 will be discharged from the adsorption box 13. The adsorption box 13 is provided with a connecting groove 16 inside, and the separator 17 is slidably connected inside the connecting groove 16. The separator 17 can divide the inside of the adsorption box 13 into two parts, which can increase the contact area between the exhaust gas and the activated carbon particles 18, thereby enhancing the exhaust gas absorption and treatment effect.
