Description

Technical Field

[0001] This utility model relates to the field of toluene waste gas treatment technology, specifically to a toluene waste gas adsorption device. Background Technology

[0002] Toluene is widely used in the pharmaceutical and chemical industries as an excellent solvent. Toluene is a common volatile organic compound with an irritating odor and is harmful to human health and the environment. Therefore, the treatment of toluene waste gas is crucial and it needs to be treated before being discharged. Traditionally, toluene waste gas is often treated by adsorption, which requires the use of toluene waste gas adsorption devices. In existing toluene waste gas adsorption devices, toluene waste gas is usually drawn into the adsorption box by an induced draft fan. When the waste gas passes through the adsorption box, the toluene inside is absorbed by the activated carbon adsorption layer. The treated gas is then discharged from the adsorption box. Existing toluene waste gas adsorption devices have the following problems: the adsorption capacity of the activated carbon adsorption layer is limited, and after working for a period of time, it is necessary to stop working and remove and replace the activated carbon adsorption layer. The disassembly and assembly of the activated carbon adsorption layer is troublesome, and each replacement requires stopping work, which increases the treatment time of toluene waste gas. Therefore, we propose a toluene waste gas adsorption device. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a toluene waste gas adsorption device. The activated carbon adsorption layer is installed through an installation mechanism. The installation and disassembly of the activated carbon adsorption layer is simple, and only one work stoppage is required to replace the activated carbon adsorption layer three times. This reduces the downtime required in the workflow, speeds up the adsorption treatment of toluene waste gas, and can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a toluene waste gas adsorption device, including an adsorption box, an activated carbon adsorption layer installed on the inner wall of the adsorption box, and an installation mechanism; The installation mechanism includes grooves, mounting slots, sliding grooves, clearance grooves, mounting frames, slots, and inserts. The front side of the adsorption box has evenly distributed grooves. Mounting slots are located on both the upper and lower sides of the front side of each groove. Mounting frames are slidably connected to the mounting slots of the lowest groove. Activated carbon adsorption layers are installed inside each mounting frame. Sliding grooves and clearance grooves are located on the upper and lower sides of each mounting slot. Inserts are slidably connected inside each sliding groove. Slots are located on the front side of the upper surface of each mounting frame. The installation mechanism facilitates the installation of the activated carbon adsorption layers. The activated carbon adsorption layers are easy to install and remove, and only one work stoppage is required after replacing the activated carbon adsorption layers three times, reducing downtime in the workflow and accelerating the adsorption treatment of toluene waste gas.

[0005] Furthermore, the installation mechanism also includes springs and protective components. Springs are provided inside the slide grooves, and the springs are located between the upper surface of the adjacent inserts and the inner wall of the slide grooves. Protective components are provided on the front side of the grooves to facilitate the downward movement of the inserts and to protect against accidental contact that could affect the treatment of exhaust gas.

[0006] Furthermore, the protective component includes a rotating shaft, a stop block, a protective cover, and perforations. The front side of each groove is rotatably connected to a uniformly distributed rotating shaft, and the front end of each rotating shaft is provided with a stop block. A protective cover is provided between four rotating shafts located in the same groove. The front side of each protective cover is provided with uniformly distributed perforations, and the rotating shafts are slidably connected to the interior of adjacent perforations to facilitate the installation of the protective cover.

[0007] Furthermore, it also includes a microcontroller, which is located on the left side of the adsorption box. The input terminal of the microcontroller is electrically connected to an external power supply to facilitate the normal operation of the equipment.

[0008] Furthermore, an exhaust pipe is provided at the exhaust hole on the upper surface of the adsorption box, and an induced draft fan is provided on the right side of the adsorption box. The exhaust port of the exhaust pipe is connected to the air inlet of the induced draft fan, and the input end of the induced draft fan is electrically connected to the output end of the microcontroller, so as to facilitate the intake of toluene waste gas into the adsorption box.

[0009] Furthermore, an air inlet pipe is provided at the air inlet on the lower surface of the adsorption box, and a valve is connected in series in the middle of the outer surface of the air inlet pipe to facilitate the control of the intake of toluene waste gas.

[0010] Furthermore, the inner wall of the mounting groove is provided with a sealing ring on the front side. The inner wall of the sealing ring on the mounting groove, which contains an activated carbon adsorption layer, is in contact with the outer surface of the adjacent mounting frame to prevent toluene waste gas leakage.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This toluene waste gas adsorption device has the following advantages: 1. To install the activated carbon adsorption layer, remove the protective cover, move the insert block upwards, and then insert the mounting frame with the new activated carbon adsorption layer into the mounting slot. Release the insert block, move it downwards into the slot, and fix the mounting frame in the mounting slot. This completes the installation of the activated carbon adsorption layer. To remove the activated carbon adsorption layer, remove the protective cover and pull the mounting frame outwards to remove the activated carbon adsorption layer. The installation of the activated carbon adsorption layer is completed through the installation mechanism. The installation and removal of the activated carbon adsorption layer is simple and saves time.

[0012] 2. When there is a groove above the activated carbon adsorption layer, the waste gas that has already passed through the old activated carbon adsorption layer is already treated when a new activated carbon adsorption layer is installed. The new activated carbon adsorption layer is installed first, and the old activated carbon adsorption layer is removed without stopping the operation. When there is no groove above the activated carbon adsorption layer, the valve and the induced draft fan need to be closed and the operation stopped. Then, the new activated carbon adsorption layer is installed into the bottom groove. Replacing the activated carbon adsorption layer three times only requires stopping the operation once, reducing the downtime required in the workflow and speeding up the adsorption treatment of toluene waste gas.

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.

[0016] Please see Figures 1-5This embodiment provides a technical solution: a toluene waste gas adsorption device, including an adsorption box 1, an activated carbon adsorption layer 3 installed on the inner wall of the adsorption box 1, an installation mechanism 4, and a microcontroller 2. The microcontroller 2 is located on the left side of the adsorption box 1, and its input terminal is electrically connected to an external power source. An exhaust pipe 5 is provided at the exhaust hole on the upper surface of the adsorption box 1. An induced draft fan 6 is provided on the right side of the adsorption box 1, and the exhaust port of the exhaust pipe 5 is connected to the air inlet of the induced draft fan 6. The input terminal of the induced draft fan 6 is... The output terminal of the microcontroller 2 is electrically connected. An air inlet pipe 7 is provided at the air inlet on the lower surface of the adsorption box 1. A valve 8 is connected in series in the middle of the outer surface of the air inlet pipe 7. When the valve 8 is opened, the blower 6 works to draw toluene waste gas into the adsorption box 1 through the air inlet pipe 7 under the control of the microcontroller 2. As the toluene waste gas moves from bottom to top in the adsorption box 1, it passes through two layers of activated carbon adsorption layer 3. The toluene in the waste gas is adsorbed by the activated carbon adsorption layer 3. The treated gas is discharged from the adsorption box 1 through the exhaust pipe 5 and the blower 6. Mounting mechanism 4 includes a groove 41, a mounting groove 42, a sliding groove 43, a clearance groove 44, a mounting frame 45, a slot 46, and an insert 47. The front side of the adsorption box 1 has evenly distributed grooves 41. Mounting grooves 42 are provided on both the upper and lower sides of the front side of the grooves 41 (there are three grooves 41, with the lowest groove 41 containing an activated carbon adsorption layer 3). Mounting frames 45 are slidably connected to the mounting grooves 42 of the lowest groove 41. Activated carbon adsorption layers 3 are provided inside each mounting frame 45. Sliding grooves 43 and clearance grooves 44 are provided on the upper and lower sides of the mounting grooves 42, respectively. Inserts 47 are slidably connected inside each sliding groove 43. Slots 46 are provided on the front side of the upper surface of the mounting frame 45 (the rear side of the insert 47...). The mounting mechanism 4 is inclined. When the mounting frame 45 and activated carbon adsorption layer 3 are present inside the mounting groove 42, the lower end of the insert 47 is inserted into the interior of the adjacent slot 46. When the mounting frame 45 and activated carbon adsorption layer 3 are not present inside the mounting groove 42, the lower end of the insert 47 is inserted into the interior of the adjacent clearance groove 44. The mounting mechanism 4 also includes springs 48 and protective components 49. Springs 48 are provided inside the sliding groove 43. The springs 48 are located between the upper surface of the adjacent insert 47 and the inner wall of the sliding groove 43. Protective components 49 are provided on the front side of the groove 41. The protective components 49 include a rotating shaft 491, a stop 492, a protective cover 493, and a perforation 494. The front side of the groove 41 is rotatably connected to evenly distributed rotating shafts 49. 1. Each rotating shaft 491 has a stop 492 at its front end. A protective cover 493 is provided between four rotating shafts 491 located in the same groove 41. The front side of the protective cover 493 has evenly distributed perforations 494. The rotating shafts 491 are slidably connected to the interior of adjacent perforations 494. The front side of the inner wall of the mounting groove 42 is provided with a sealing ring 9. The inner wall of the sealing ring 9 on the mounting groove 42 containing the activated carbon adsorption layer 3 is in contact with the outer surface of the adjacent mounting frame 45. When the activated carbon adsorption layer 3 needs to be replaced, first rotate the rotating shaft 491 of the groove 41 above the activated carbon adsorption layer 3 until the stop 492 corresponds to the perforation 494 on the corresponding protective cover 493. Then the protective cover 493 can be removed and moved upwards. Move the insert block 47, which is then compressed and fitted to the groove 48. Next, insert the mounting frame 45 with the new activated carbon adsorption layer 3 into the mounting slot. Release the insert block 47; under the rebound force of the spring 48 and gravity, the insert block 47 moves downwards and inserts into the slot 46, fixing the mounting frame 45 in the mounting slot 42, completing the installation of the activated carbon adsorption layer 3. Then, reinstall the protective cover 493. Afterwards, open the protective cover 493 on the used activated carbon adsorption layer 3 and pull the mounting frame 45 outwards. Because the lower rear side of the insert block 47 is inclined, the movement of the mounting frame 45 pushes the insert block 47 upwards through the slot 46, causing the insert block 47 to retract into the sliding groove 43. The presence of the sealing ring 9 prevents the leakage of untreated waste gas.When the mounting frame 45 moves to the front of the insert block 47 (at this time, the mounting frame 45 has not yet been completely removed from the mounting groove 42), under the action of the spring 48's rebound force and gravity, the insert block 47 moves downward and inserts into the clearance groove 44, completing the sealing of the exhaust gas to prevent untreated exhaust gas leakage. Then, the protective cover 493 can be reinstalled. When there is a groove 41 above the activated carbon adsorption layer 3, the exhaust gas that has passed through the old activated carbon adsorption layer 3 is already treated when a new activated carbon adsorption layer 3 is installed. The new activated carbon adsorption layer 3 is installed first, and then the old activated carbon adsorption layer 3 is removed without stopping the work. When there is no groove 41 above the activated carbon adsorption layer 3, the valve 8 and the induced draft fan 6 need to be closed and the work stopped. Then, the new activated carbon adsorption layer 3 is installed into the bottom groove 41. Replacing the activated carbon adsorption layer 3 three times only requires stopping the work once, reducing the downtime required in the workflow and accelerating the adsorption treatment of toluene exhaust gas.

[0017] The working principle of the toluene waste gas adsorption device provided by this utility model is as follows: When valve 8 is opened, the induced draft fan 6, controlled by the microcontroller 2, draws the toluene waste gas into the adsorption box 1 through the inlet pipe 7. As the toluene waste gas moves upwards within the adsorption box 1, it passes through two layers of activated carbon adsorption 3. The toluene in the waste gas is adsorbed by the activated carbon adsorption layer 3. The treated gas is discharged from the adsorption box 1 through the exhaust pipe 5 and the induced draft fan 6. When the activated carbon adsorption layer 3 needs to be replaced, first rotate the shaft 491 of the groove 41 above the activated carbon adsorption layer 3 until the stop block 492 aligns with the corresponding protective cover 4. Align the perforation 494 on 93 with the protective cover 493, then remove the protective cover 493. Move the insert 47 upwards, at which point the insert 47 is compressed and fitted 48. Then insert the mounting frame 45 with the new activated carbon adsorption layer 3 into the mounting slot. Then release the insert 47. Under the action of the spring 48's rebound force and gravity, the insert 47 moves downwards and inserts into the slot 46, fixing the mounting frame 45 in the mounting slot 42, completing the installation of the activated carbon adsorption layer 3. Then reinstall the protective cover 493. Afterwards, open the protective cover 493 on the used activated carbon adsorption layer 3 and pull the mounting frame 4 outwards. 5. Because the lower rear side of the insert 47 is inclined, the movement of the mounting frame 45 pushes the insert 47 upward through the slot 46, causing the insert 47 to retract into the slide groove 43. Due to the presence of the sealing ring 9, leakage of untreated waste gas is prevented. When the mounting frame 45 moves to the front of the insert 47 (at this time, the mounting frame 45 has not yet completely moved out of the mounting groove 42), under the action of the spring force 48 and gravity, the insert 47 moves downward and inserts into the clearance groove 44, completing the sealing of the waste gas and preventing leakage of untreated waste gas. Then, the protective cover 493 can be reinstalled. When the activated carbon adsorption layer When there is a groove 41 above the activated carbon adsorption layer 3, the exhaust gas that has already passed through the old activated carbon adsorption layer 3 is already treated when a new activated carbon adsorption layer 3 is installed. The new activated carbon adsorption layer 3 is installed first and the old activated carbon adsorption layer 3 is removed without stopping the work. When there is no groove 41 above the activated carbon adsorption layer 3, valve 8 and induced draft fan 6 need to be closed and the work stopped. Then the new activated carbon adsorption layer 3 is installed into the bottom groove 41. Replacing the activated carbon adsorption layer 3 three times only requires stopping the work once, reducing the time required to stop the work in the process and speeding up the adsorption treatment of toluene exhaust gas.

[0018] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an MM32SPIN080G, the induced draft fan 6 can be a CF series centrifugal small induced draft fan, and the microcontroller 2 controls the operation of the induced draft fan 6 using methods commonly used in the prior art.
