Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment devices, in particular to an industrial waste gas odor adsorption and purification device. Background Art

[0002] The treatment of odor in industrial waste gas is a key link in the field of environmental protection, and the adsorption method is widely used due to its high efficiency and economy. This method relies on the porous structure and surface activity of the adsorbent to capture odor molecules in the waste gas through physical adsorption or chemical adsorption mechanisms. Common adsorbents include activated carbon and molecular sieves. Among them, activated carbon has a significant adsorption effect on volatile organic compounds (VOCs), sulfides and other odor substances due to its large specific surface area and developed pores. In industrial applications, the adsorption method can be flexibly adapted to waste gas treatment scenarios in multiple industries such as chemical, coating, and printing, and directional removal of odors can be achieved through fixed bed, moving bed and other equipment. Its advantages are stable treatment efficiency and simple operation, and some adsorbents can be reused after regeneration, which reduces secondary pollution while reducing treatment costs, becoming one of the mainstream technologies for industrial odor control.

[0003] Traditional adsorption devices mostly adopt a single-tower structure. When the adsorbent is saturated and needs to be replaced, the operation must be stopped and the tower body must be disassembled, resulting in production line interruption. The entire tower body must be emptied when the adsorbent is replaced, which is a complicated and time-consuming operation.

[0004] To this end, those skilled in the art have proposed an industrial waste gas odor adsorption and purification device to solve the problems raised in the background technology. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides an industrial waste gas odor adsorption and purification device to solve the problem that the adsorption device in the prior art mostly adopts a single tower structure. When the adsorbent is saturated and needs to be replaced, the operation must be stopped and the tower body must be disassembled, resulting in production line interruption and other problems.

[0006] An industrial waste gas odor adsorption and purification device comprises: an adsorption tower, the top of the adsorption tower is connected to an input pipe, and the bottom of the adsorption tower is connected to a discharge port;

[0007] A three-way assembly includes a connecting pipe and an air inlet pipe. The connecting pipe is connected between the two adsorption towers. The air inlet pipe is fixed to the circumference of the connecting pipe. The inner wall of the connecting pipe is installed with a first control valve and a second control valve.

[0008] Several adsorption bins are arranged around the adsorption tower; a guide rail is fixed on the inner wall of the adsorption bin, a temperature and humidity sensor and a VOC concentration sensor are installed under the adsorption bin, a sliding frame is slidably fitted on the guide rail, an adsorbent is arranged in the sliding frame, and a sealing plate is installed on the outer wall of the adsorption bin.

[0009] Through the above technical solution, parallel redundancy of dual adsorption towers is achieved, and independent valve control is used to ensure zero interruption of waste gas treatment; when any tower is maintained, the standby tower takes over immediately to ensure continuous operation of the production line; the independent sub-compartment design of the adsorption chamber supports targeted purification and on-demand replacement; the guide rail-guided sliding frame realizes rapid withdrawal and maintenance of the adsorbent, greatly shortening downtime; temperature, humidity and VOC concentration sensors coordinate monitoring, accurately feedback the adsorption status of each chamber, and provide real-time data support for intelligent decision-making.

[0010] Preferably, a mounting seat is fixedly connected to the adsorption bin port, and a plurality of bolts are installed between the mounting seat and the sealing plate.

[0011] Through the above technical solution, the bolt connection ensures high-pressure sealing of the adsorption chamber flange surface, eliminating the risk of exhaust gas leakage.

[0012] Preferably, a handle is fixedly connected to the surface of the sealing plate.

[0013] Preferably, a snap-on disassembly assembly is provided between the sliding frame and the adsorption bin, and the snap-on disassembly assembly includes a positioning plate, an end cover, a return spring and a clamping block. The positioning plate is fixed to the front end face of the adsorption bin, and the front end face of the sliding frame is fixedly connected to the end cover. A spring groove is provided on the upper surface of the end cover, and the inner surface of the spring groove is connected to the return spring. One end of the return spring is connected to a connecting plate, and the clamping block is fixed to the upper surface of the connecting plate. A positioning groove is provided on the bottom surface of the positioning plate, and the clamping block is engaged with the positioning groove.

[0014] Preferably, a through slot is passed through the side wall of the spring slot, a shift plate is fixedly connected to the side wall of the connecting plate, the shift plate is slidably matched with the through slot, and a buckle slot is provided on the front end surface of the end cover, the position of the buckle slot is adapted to the shift plate.

[0015] Through the above technical solution, the spring self-locking mechanism of the card block and the positioning slot enables the sliding frame to be locked in one second; unlocking with a single finger eliminates the need for tools and improves maintenance efficiency.

[0016] Preferably, a water inlet is connected to the top wall of the adsorption tower, and an atomizing spray head is installed at one end of the water inlet.

[0017] Preferably, a plurality of guide plates are fixed to the top wall of the adsorption tower, and the guide plates are located below the atomizing spray head.

[0018] Through the above technical solutions, spraying dust reduction and humidity adjustment optimize the exhaust gas working conditions and reduce the subsequent adsorption load; the guide plate forces the airflow to be evenly distributed to avoid local overload; the airflow is immediately dispersed by the guide plate after spraying, which improves the gas-liquid contact efficiency and prevents droplets from gathering and clogging the adsorption layer.

[0019] Preferably, it further comprises: an intelligent control system, wherein the intelligent control system receives monitoring data from the temperature and humidity sensor and the VOC concentration sensor in real time;

[0020] When the monitoring data continuously exceeds the preset threshold, it is determined that the currently working adsorption tower has reached a saturated state; the control valve corresponding to the currently saturated adsorption tower is automatically closed, and the control valve of the standby adsorption tower is opened at the same time.

[0021] Through the above technical solution, the saturation state is dynamically determined based on multi-sensor data, and the dual-tower valves are automatically switched, eliminating the risk of excessive emissions caused by delays in manual intervention.

[0029] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0030] Example 1: As shown in the attached Figure 1 To the attached Figure 3 As shown: The present invention provides an industrial waste gas odor adsorption and purification device, including an adsorption tower 1 and a three-way assembly:

[0031] The top of the adsorption tower 1 is connected to an input pipe 2, and the bottom of the adsorption tower 1 is connected to a discharge port 29. The adsorption tower 1 is a core purification container, and the exhaust gas is introduced through the top input pipe 2 and the clean gas is discharged through the bottom discharge port 29;

[0032] The three-way assembly includes a connecting pipe 3 and an air inlet pipe 4. The connecting pipe 3 is connected between the two adsorption towers 1. The air inlet pipe 4 is fixed to the side of the connecting pipe 3. The inner wall of the connecting pipe 3 is installed with a first control valve 5 and a second control valve 6. The connecting pipe 3 connects the two towers to realize the gas circuit parallel connection. The exhaust gas is diverted to each tower through the air inlet pipe 4. The first control valve 5 and the second control valve 6 independently control the on and off of the two towers to support the switching of the two towers.

[0033] Several adsorption chambers 10 are arranged around the adsorption tower 1; a guide rail 11 is fixed to the inner wall of the adsorption chamber 10, which can guide the sliding frame 12 to be accurately pulled out. A temperature and humidity sensor 18 and a VOC concentration sensor 1801 are installed below the adsorption chamber 10; the temperature and humidity sensor 18 monitors the humidity of the adsorption environment in real time; the VOC concentration sensor 1801 monitors the adsorption saturation of pollutants; a sliding frame 12 is slidably fitted on the guide rail 11, and an adsorbent 13 is arranged in the sliding frame 12. The sliding frame 12 carries the adsorbent 13 and can be quickly replaced along the guide rail; a sealing plate 14 is installed on the outer wall of the adsorption chamber 10;

[0034] A mounting base 15 is fixedly connected to the port of the adsorption bin 10, and several bolts 16 are installed between the mounting base 15 and the sealing plate 14; a handle 17 is fixedly connected to the surface of the sealing plate 14; the sealing plate 14 is fixed to the mounting base 15 by the bolts 16 to ensure airtightness; the handle 17 can assist in opening the sealing plate.

[0035] The top wall of the adsorption tower 1 is connected to a water inlet 8, one end of which is equipped with an atomizing spray head 7, and the water inlet 8 is connected to an external water source; the atomizing spray head 7 sprays atomizingly to reduce dust and adjust humidity; the guide plate 9 evenly distributes the airflow to improve the pretreatment efficiency; a number of guide plates 9 are fixed to the top wall of the adsorption tower 1, and the guide plates 9 are located below the atomizing spray head 7.

[0036] It also includes: an intelligent control system, which is configured to: receive monitoring data from the temperature and humidity sensors 18 and the VOC concentration sensors 1801 in each adsorption chamber 10 in real time;

[0037] When the monitoring data continuously exceeds the preset threshold, it is determined that the currently working adsorption tower 1 has reached a saturated state; the control valve corresponding to the currently saturated adsorption tower is automatically closed, and the control valve of the standby adsorption tower is opened at the same time.

[0038] Industrial waste gas enters the currently working adsorption tower 1 through the inlet pipe 2. It is first pre-treated by atomizing spray nozzle 7 supplied with water from the water inlet 8. The spray droplets combine with the particulate matter and soluble substances in the waste gas and settle. After the air flow is evenly dispersed by the guide plate 9 below, the waste gas enters multiple adsorption chambers 10 distributed around the side of the adsorption tower 1.

[0039] In the adsorption chamber 10, the exhaust gas penetrates the adsorbent 13 (such as activated carbon or molecular sieve) filled in the sliding frame 12, and the odorous substances are adsorbed and intercepted, and the purified gas is discharged from the exhaust port 29;

[0040] During this process, the temperature and humidity sensor 18 at the bottom of each adsorption chamber 10 continuously monitors the changes in ambient humidity, and the VOC concentration sensor 1801 detects the pollutant adsorption efficiency in real time. The data of the two types of sensors are synchronously transmitted to the intelligent control system;

[0041] When the system analysis finds that the sensor data of multiple adsorption bins 10 in a certain adsorption tower 1 are continuously abnormal (such as the cumulative increase in humidity is accompanied by a stagnant decrease in pollutant concentration), it is determined that the tower adsorbent 13 is saturated and failed, and a control instruction is immediately generated: close the control valve corresponding to the current saturated adsorption tower (if the current operating tower is controlled by the first control valve 5, close valve 5, if it is controlled by the second control valve 6, close valve 6), and at the same time open the control valve of another spare adsorption tower (close valve 5 and open valve 6, close valve 6 and open valve 5), so that the exhaust gas is automatically switched to the air inlet pipe 4 of the spare adsorption tower through the connecting pipe 3, so as to achieve uninterrupted continuation of the purification process; for the saturated adsorption bin 10 that needs maintenance, in Example 1, the operator loosens the bolts 16 on the mounting seat 15, holds the handle 17 to remove the sealing plate 14, pulls out the sliding frame 12 horizontally along the guide rail 11, replaces the adsorbent 13, and resets and locks it.

[0042] As can be seen above, industrial waste gas enters the adsorption tower 1 from the top input pipe 2; when the airflow passes through the atomizing spray head 7 and the water source comes from the water inlet 8, the water mist captures dust and soluble matter and forms sediment; then it hits the guide plate 9 and is forced to diffuse and flow evenly downward; then the waste gas penetrates the three vertically distributed adsorption chambers from top to bottom:

[0043] The third adsorption chamber 1003 (uppermost layer): filled with hydrogen sulfide modified activated carbon, which preferentially adsorbs highly polar odor substances such as sulfur compounds;

[0044] The second adsorption chamber 1002 (middle layer): filled with high specific surface area activated carbon, adsorbing volatile organic compounds (VOCs) and neutral odor components;

[0045] The first adsorption chamber 1001 (the bottom layer): filled with hydrophobic zeolite to deeply remove residual water molecules and ensure that the outlet gas is dry;

[0046] The exhaust gas is purified layer by layer and then discharged from the bottom discharge port 29.

[0047] Layered saturation determination and intelligent switching:

[0048] The third adsorption chamber 1003 is saturated: the temperature and humidity sensor 18 at its bottom detects a rise in sulfide concentration (modified carbon failure), and the VOC concentration sensor 1801 indicates pollutant penetration;

[0049] The second adsorption chamber 1002 is saturated: the VOC concentration detected by the middle sensor 1801 remains constant (the activated carbon adsorption capacity is exhausted);

[0050] The first adsorption chamber (1001) is saturated: the humidity detected by the lower sensor 18 increases, i.e. the moisture absorption capacity of the zeolite decreases;

[0051] When the abnormal data of any warehouse persists, the intelligent system determines that the tower is inefficient; it immediately closes the control valve of the current tower and opens the control valve of the standby tower simultaneously, and the exhaust gas is switched to the standby tower inlet pipe 4 through the connecting pipe 3.

[0052] Loosen the bolts 16 of the mounting base 15 of the target adsorption bin (such as 1002), and hold the handle 17 to remove the sealing plate 14; pull out the sliding frame 12 of the bin horizontally along the guide rail 11, and keep the other two bins 1001 and 1003 in place; after replacing the activated carbon in the second adsorption bin 1002, push back the sliding frame 12 and reset the sealing plate 14 and tighten the bolts 16.

[0053] The vertically layered design of the multi-layer adsorption chamber achieves deep purification of waste gas. The upper layer of hydrogen sulfide-modified activated carbon targets the adsorption of sulfur-containing compounds, the middle layer of high-specific surface area activated carbon efficiently captures VOCs, and the lower layer of hydrophobic zeolite thoroughly removes residual water vapor, specifically solving the problem of purifying industrial waste gas with complex components.

[0054] The dual-tower parallel connection and intelligent valve control build an uninterrupted operation system: when any adsorption bin sensor detects saturation characteristics (such as the rise of sulfide in bin 1003, the flat VOC concentration in bin 1002, and the accumulation of humidity in bin 1001), the system immediately closes the current tower control valve and opens the standby tower valve. The exhaust gas is seamlessly switched through the connecting pipe 3 to ensure continuous operation of the production line; the installation stability and sealing of the adsorption bin 10 are guaranteed by the bolts 16 and the sealing plate 14: only the bolts 16 of the target bin need to be loosened, the sealing plate 14 can be removed by holding the handle 17, and the sliding frame 12 can be horizontally pulled out along the guide rail 11 to replace the adsorbent 13, which effectively reduces the maintenance time of a single bin without affecting the operation of other bins, thereby improving the replacement efficiency of the entire tower.

[0055] Example 2: As shown in the attached Figure 2As shown: This embodiment is basically the same as the previous embodiment, except that a snap-on disassembly assembly is provided between the sliding frame 12 and the adsorption bin 10, and the snap-on disassembly assembly includes a positioning plate 19, an end cover 21, a return spring 23 and a block 25. The positioning plate 19 is fixed to the front end face of the adsorption bin 10, and the front end face of the sliding frame 12 is fixedly connected to the end cover 21. A spring groove 22 is provided on the upper surface of the end cover 21, and the inner surface of the spring groove 22 is connected to the return spring 23. One end of the return spring 23 is connected to a connecting plate 24, and the block 25 is fixed to the upper surface of the connecting plate 24. The bottom surface of the positioning plate 19 is provided with a positioning groove 22. 0, the block 25 is engaged with the positioning groove 20; by setting the snap disassembly component, the sliding frame 12 can be quickly assembled. When installing the sliding frame 12, the sliding frame 12 is completely pushed into the guide rail 11. When the sliding frame 12 is fully engaged, the block 25 reaches the positioning plate 19. At this time, the wedge-shaped surface of the block 25 is squeezed by the bottom surface of the positioning plate 19, and the block 25 is pressed into the spring groove 22. When the position of the spring groove 22 is aligned with the positioning groove 20, the block 25 loses resistance. At this time, the reset spring 23 is quickly reset, and the block 25 is locked into the positioning groove 20, thereby quickly locking and fixing the sliding frame 12.

[0056] A through slot 26 is formed on the side wall of the spring slot 22, and a shift plate 27 is fixedly connected to the side wall of the connecting plate 24. The shift plate 27 is slidably engaged with the through slot 26, and a buckle slot 28 is formed on the front end surface of the end cover 21. The position of the buckle slot 28 is adapted to the shift plate 27.

[0057] When the sliding frame 12 needs to be disassembled to replace the adsorbent 13, hold the hand in the buckle groove 28 and then use the thumb to push the dial plate 27 down. At this time, the dial plate 27 drives the connecting plate 24 and the block 25 to move downward. When the block 25 is out of the positioning groove 20, the limit of the block 25 is released, so that the sliding frame 12 can be quickly pulled out as a whole.

[0058] As can be seen from the above, when the sliding frame 12 needs to be replaced, insert your finger into the buckle groove 28 to move the paddle 27, driving the connecting plate 24 to compress the return spring 23 to disengage the card block 25 from the positioning groove 20. After releasing the lock, directly pull out the sliding frame 12. After replacement, release the paddle 27, and the return spring 23 pushes the card block 25 to automatically snap into the positioning groove 20 to complete the fixation.

[0059] Through the coordinated positioning of the positioning plate 19 and the end cover 21, the return spring 23 drives the card block 25 to automatically embed into the positioning groove 20 to achieve 12-second locking of the sliding frame. When disassembling, you only need to insert your finger into the buckle groove 28 and turn the dial plate 27. The connecting plate 24 compresses the spring to make the card block 25 disengage the groove and then directly pull it out of the sliding frame 12. No tools are required throughout the process and the unlocking can be completed quickly with one hand, which is suitable for high-frequency maintenance scenarios; the wedge-shaped surface of the card block 25 and the extrusion adaptability of the positioning plate 19 provide reliable locking force, and the overall packaging structure of the end cover 21 effectively isolates the exhaust gas corrosion.

[0060] Example 3: This example has the same structure as Example 1, and the only difference is the combination of the adsorbent 13 in the adsorption chamber 10:

[0061] The third adsorption chamber 1003 is filled with alkaline activated alumina, which is used to neutralize and adsorb acidic gases such as hydrogen chloride and hydrogen fluoride;

[0062] The second adsorption chamber 1002 is filled with hydrophobic silica gel to preferentially remove moisture from high-humidity exhaust gas;

[0063] The first adsorption chamber 1001 is filled with impregnated activated carbon to adsorb alkaline odor substances such as ammonia and amines; the rest of the structure is the same as that of the first embodiment.

[0064] Working principle: Acidic waste gas enters the adsorption tower 1 through the inlet pipe 2, passes through the spray head 7 for dust reduction, the guide plate 9 for flow uniformity, and then penetrates from top to bottom:

[0065] The upper layer of alkaline activated alumina neutralizes acidic gases;

[0066] The middle layer of hydrophobic silica gel deeply dehumidifies;

[0067] The lower layer is impregnated with activated carbon to absorb alkaline odors;

[0068] When the pH value of any bin sensor, such as bin 1003, rises and the ammonia concentration in bin 1001 remains flat, indicating saturation, the intelligent system switches to the standby tower operation; during maintenance, loosen the bolt 16 of the target bin and pull out the sliding frame 12 to replace the adsorbent 13.

[0069] Example 4: This example has the same structure as Example 1, and adjusts the hierarchical functional combination of the adsorbent 13, specifically for treating industrial waste gas containing acidic and alkaline mixed components.

[0070] The third adsorption chamber 1003 is filled with high-density alkaline activated alumina particles, coated with sodium hydroxide, specifically designed to neutralize and adsorb acidic gas components (such as hydrogen chloride, hydrogen fluoride, and sulfur dioxide). When acidic waste gas penetrates this layer, the alumina's microporous structure physically adsorbs the acidic molecules, while the sodium hydroxide undergoes an acid-base neutralization reaction to form stable salts, eliminating corrosive gases at the source.

[0071] Second adsorption chamber 1002: Filled with modified hydrophobic silica gel, enhanced through silanization, it preferentially captures water molecules in high-humidity exhaust gas. Its unique selectivity binds to the water vapor produced by the reaction of the upper acidic substances, preventing the water from diffusing downstream and ensuring the activity of the adsorbent in the lower layer.

[0072] First adsorption chamber 1001: Filled with phosphoric acid-impregnated activated carbon, the phosphoric acid combines with the hydroxyl groups on the activated carbon's surface to form acidic active sites, specifically targeting the adsorption of alkaline odorous substances (such as ammonia and trimethylamine). The chemical bonding of the impregnated carbon enhances its ability to capture polar molecules, thoroughly purifying residual alkaline pollutants.

[0073] The acidic mixed waste gas enters the adsorption tower 1 from the input pipe 2 and is sprayed by the atomizing spray head 7:

[0074] The spray droplets envelop the dust and soluble acidic substances (such as SO2) to form a liquid film and settle;

[0075] The residual gaseous acidic components (such as HCl) rise to the third adsorption chamber 1003 and react with the basic alumina:

[0076] HCl + NaOH → NaCl + H2O;

[0077] SO2+2NaOH→Na2SO3+H2O.

[0078] The water vapor generated by the reaction and the original moisture in the exhaust gas are retained by the hydrophobic silica gel in the second adsorption chamber 1002;

[0079] The dry exhaust gas continues to flow downward to the first adsorption chamber 1001, where the phosphoric acid-impregnated carbon adsorbs ammonia through hydrogen bonding and ion exchange: NH3+H3PO4→NH4H2PO4;

[0080] Finally, the purified gas is discharged from the discharge port 29 in compliance with the standards.

[0081] Saturation determination and maintenance:

[0082] The failure characteristics are as follows: Third adsorption chamber 1003: The temperature and humidity sensor 18 detects a rise in pH value (alkalinity depletion), and the VOC sensor 1801 shows acid gas penetration;

[0083] Second adsorption chamber 1002: humidity is continuously higher than the set threshold (silica gel is saturated with moisture);

[0084] First adsorption chamber 1001: Ammonia concentration sensor alarm (impregnated carbon active sites are saturated).

[0085] Intelligent response: When the data of any warehouse is abnormal, the system closes the current tower control valve and opens the standby tower valve to switch the gas path.

[0086] Replace the corresponding adsorbent 13:

[0087] Replace basic alumina in warehouse 1003 (neutralization reaction products need to be safely disposed of);

[0088] Replace the hydrophobic silica gel in warehouse 1002 (can be dried, regenerated and reused);

[0089] Replace the impregnated carbon in warehouse 1001 (chemical adsorbent cannot be regenerated).
