Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment system based on waste gas purification function. Background Technology

[0002] Industrial wastewater typically contains a certain concentration of waste gases, including organic waste gases and odorous gases. Indiscriminate discharge of these gases can severely impact and damage the surrounding ecological environment. Therefore, industrial wastewater treatment should integrate the treatment of waste gases and wastewater, continuously optimizing the treatment processes to improve the quality of pollution purification.

[0003] For example, patent CN221397447U discloses a wastewater processor with gas purification function, including a base plate and a wastewater processor installed on top for treating wastewater. One side of the wastewater processor is provided with a waste gas pretreatment component for pretreating waste gas. The waste gas pretreatment component includes an inlet pipe installed on one side of the wastewater processor. The other end of the inlet pipe is connected to a gas-liquid separator for separating waste gas from wastewater. The other side of the gas-liquid separator is connected to a first connecting pipe, and the other end of the first connecting pipe is provided with a dust collector for removing dust from the waste gas. The technical effect is that, through the coordinated use of the gas-liquid separator, dust collector, and filter box, the waste gas in the wastewater can be effectively pretreated, effectively removing pollutants such as dust, particulate matter, and grease from the waste gas, improving the waste gas treatment effect, and reducing the impact on the environment and human health.

[0004] Currently, most dust collectors for waste gas treatment use bag filters, which filter particulate matter in the waste gas to achieve dust removal. However, after a period of use, existing bag filters accumulate adhering impurities on the filter bags. While traditional dust collectors are equipped with pulse-jet cleaning components to remove these impurities, air blowing alone is insufficient for thorough cleaning. Especially when the backflushing airflow reaches the lower part of the filter bag, the airflow weakens significantly, greatly reducing the cleaning effect. This results in a large amount of impurities remaining at the bottom of the bag. Over time, these residual impurities accumulate and clog the filter bags, affecting their dust removal and purification efficiency. Therefore, regular manual cleaning of the filter bags is necessary, which is time-consuming and labor-intensive.

[0005] In addition, existing wastewater treatment systems typically discharge the treated water directly, failing to utilize the resources and resulting in waste. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by providing a wastewater treatment system based on exhaust gas purification.

[0007] The present invention is achieved through the following technical solution: a wastewater treatment system based on exhaust gas purification function, including a wastewater primary filter, the outlet end of the wastewater primary filter is connected to a gas-liquid separator, the outlet end of the gas-liquid separator is connected to a wastewater treatment tank for purifying wastewater, and the outlet end of the gas-liquid separator is connected to a dust collector for purifying exhaust gas. The dust collector includes a dust collector body, within which a horizontal partition is fixed. Multiple rows of filter bags are arranged laterally at the bottom of the partition. Each row of filter bags includes multiple filter bags arranged longitudinally, and each row is equipped with a cleaning assembly. The cleaning assembly includes a lifting plate located below the filter bags and two beaters symmetrically distributed on both sides of the filter bags. Both the lifting plate and the beaters extend along the arrangement direction of the multiple filter bags. Multiple upper linkage mechanisms are provided between the partition and the two beaters, arranged along the length of the beaters. Each upper linkage mechanism includes two upper connecting rods and two upper... The lower ends of the upper connecting rods are respectively hinged to the two striking rods, and the upper ends of the two upper connecting rods are both hinged to the partition plate. The distance between the upper ends of the two upper connecting rods is smaller than the distance between the lower ends of the two upper connecting rods. Multiple sets of lower connecting rod mechanisms are provided between the lifting plate and the two striking rods, arranged along the length of the striking rods. The lower connecting rod mechanism includes two lower connecting rods. The upper ends of the two lower connecting rods are respectively hinged to the bottom of the two striking rods, and the lower ends of the two lower connecting rods are both hinged to the top of the lifting plate. The distance between the lower ends of the two lower connecting rods is smaller than the distance between the upper ends of the two lower connecting rods. The dust collector body is also provided with a lifting mechanism that drives the lifting plate to move upward.

[0008] In this system, wastewater undergoes preliminary filtration through a primary wastewater filter to remove larger impurities and debris, preventing clogging and deposition in subsequent equipment. A gas-liquid separator then separates the pre-filtered wastewater into waste gas, achieving separate treatment of wastewater and waste gas. The wastewater enters a wastewater treatment tank for purification to obtain purified water that meets discharge requirements, while the waste gas enters a dust collector via a third pipeline for filtration.

[0009] When purifying exhaust gas, the dust collector filters particulate matter and adsorbs impurities such as activated carbon through multi-row bag filters. After filtration, the impurities adhere to the bag filters, which are then cleaned by a cleaning assembly. During cleaning, a lifting mechanism moves the lifting plate upwards. Because the distance between the upper ends of the two lower connecting rods is greater than the distance between their lower ends, and the distance between the lower ends of the two upper connecting rods is greater than the distance between their upper ends, the two lower and two upper connecting rods spread outwards as the lifting plate rises, causing the two striking rods to move away from each other. After rising a certain distance, the lifting plate quickly descends and resets under its own weight, causing the two striking rods to move closer together and simultaneously beat the multiple bag filters in the bag assembly. This beating dislodges and removes impurities from the bag filters, improving bag filtration efficiency and ultimately enhancing the dust removal and preliminary purification efficiency of the exhaust gas.

[0010] As an optimization, the lifting plates of the dust removal assembly of the multi-row bag filter group are fixed together as a whole by a transverse connecting plate extending laterally, and the lifting mechanism drives the transverse connecting plate to move upward. This optimized solution connects the lifting plates of the multi-row bag filter group into a whole by using the transverse connecting plate. In this way, all lifting plates can move synchronously by driving the transverse connecting plate, reducing the number of lifting mechanisms required and saving costs.

[0011] As an optimization, the horizontal connecting plate is distributed with several support components along its length. Each support component includes a guide wheel rotatably connected to the horizontal connecting plate and a C-shaped guide rail fixed to the inner wall of the dust collector body. The C-shaped guide rail extends vertically and has a closed bottom, allowing the guide wheel to roll along it. This optimized design improves stability during movement by allowing the horizontal connecting plate to move up and down along the C-shaped guide rail via the guide wheel. Simultaneously, the closed bottom of the C-shaped guide rail supports the guide wheel and limits the descent distance of the lifting plate.

[0012] As an optimization, the dust removal assembly also includes a slip ring fitted at the bottom of the dust collector bag. The slip ring is fixed to the lifting plate via a vertical connecting rod, and the inner wall of the slip ring is provided with a cleaning brush that contacts the outer wall of the dust collector bag. In this optimized solution, because the slip ring is located at the bottom of the dust collector bag, when the lifting plate rises, it can simultaneously drive the slip ring upwards, allowing the internal cleaning brush to scrape the bottom of the dust collector bag. Since the bottom of the dust collector bag has the most accumulated impurities, scraping improves the cleaning effect of these impurities, prevents impurities from clumping and affecting the filtration effect of the dust collector bag, and further improves the dust removal and filtration efficiency of the dust collector bag.

[0013] As an optimization, the lifting mechanism includes a drive sprocket, a driven sprocket, a chain, a lifting block, and a drive motor. The drive sprocket and the driven sprocket are distributed vertically and are rotatably connected to the dust collector body. The drive sprocket and the driven sprocket are connected by chain drive. The drive motor is used to drive the drive sprocket to rotate. The lifting block is fixed on the outside of the chain and contacts the cross plate when the lifting block rises.

[0014] This optimized solution uses a drive motor to rotate the active sprocket, which in turn drives the driven sprocket via a chain. During chain transmission, the lifting block moves circumferentially along the chain. As it rises, the lifting block contacts the horizontal connecting plate, causing the plate to move upwards. When the lifting block reaches the top of the chain, it moves outwards and disengages from the horizontal connecting plate. At this point, the horizontal connecting plate and the lifting plate descend rapidly under their own weight. After one revolution of the chain, the lifting block contacts the horizontal connecting plate again. This cyclical process ensures continuous beating of the dust collector bag by the beating rod, guaranteeing effective removal of impurities from the bag.

[0015] As an optimization, the outlet of the gas-liquid separator is connected to the inlet of the dust collector via a third pipeline, which is also connected to an activated carbon injector. In this optimized scheme, when the exhaust gas passes through the third pipeline, the activated carbon injector sprays activated carbon into the exhaust gas. The activated carbon adsorbs odors and organic particles in the exhaust gas. Then, the dust collector filters the suspended matter, dust, and adsorbed activated carbon in the exhaust gas, achieving preliminary purification of the exhaust gas.

[0016] As an optimization, the dust collector's outlet is connected to a fan, the fan's output is connected to an exhaust gas spray tower, the exhaust gas spray tower's spray water output is connected to the wastewater input of the wastewater treatment tank via a sixth pipeline, and a first valve and a check valve are sequentially installed on the sixth pipeline along the conveying direction. The wastewater treatment tank's purified water output is connected to the exhaust gas spray tower's spray water input via a seventh pipeline, and a second valve and a first water pump are sequentially installed on the seventh pipeline along the conveying direction.

[0017] This optimized solution uses a waste gas scrubbing tower for secondary purification of waste gas. The wastewater from the scrubbing process is then transported to a wastewater treatment tank via a sixth pipeline for further purification. The purified water from the wastewater treatment tank is then returned to the waste gas scrubbing tower via a seventh pipeline for further scrubbing. This structure achieves wastewater recycling, avoids resource waste, and improves the company's economic efficiency.

[0018] As an optimization, the exhaust gas scrubbing tower includes a tower body, a gas exhaust pipe at the top of the tower body, an exhaust gas filter packing layer inside the tower body, a spray pipe fixed above the exhaust gas filter packing layer, several spray heads evenly distributed at the bottom of the spray pipe, one end of the spray pipe extending to the outside of the tower body to form the spray water inlet, an exhaust gas inlet pipe on the side wall of the tower body to form the air inlet of the exhaust gas scrubbing tower, the height of the exhaust gas inlet pipe being lower than the height of the exhaust gas filter packing layer, and a spray water outlet pipe at the bottom of the tower body to form the spray water outlet. In this optimized scheme, after the exhaust gas enters the exhaust gas scrubbing tower, it flows upward and is purified by passing through the exhaust gas filter packing layer, further removing odors and organic particulate impurities from the exhaust gas. The spray pipe sprays the packing layer, improving the reaction and purification effect, and the purified exhaust gas is discharged into the atmosphere from the gas exhaust pipe at the top.

[0019] As an optimization, the wastewater pre-filter includes a filter box with a wastewater inlet pipe at the top and a wastewater outlet pipe at the bottom, forming the outlet of the pre-filter. A horizontal filter plate is fixed inside the filter box, and a first cleaning port is provided on the side wall of the filter box, corresponding to the upper part of the filter plate. A first sealing cap is installed on the first cleaning port. This optimized wastewater pre-filter filters large particulate impurities and debris through the filter plate, and the filtered impurities can be periodically cleaned through the first cleaning port, making it convenient to use.

[0020] As an optimization, the wastewater treatment tank includes a tank body with two vertical partitions fixedly connected inside, dividing the tank body into a reaction purification chamber, a filtration purification chamber, and a water storage chamber. The reaction purification chamber is equipped with a wastewater inlet pipe forming the wastewater inlet. A feed pipe for adding chemical additives is provided at the top of the reaction purification chamber. An agitator for stirring the wastewater is provided inside the reaction purification chamber. A second water pump is fixedly installed at the bottom of the reaction purification chamber, and the output end of the second water pump is connected to the filtration purification chamber. The filtration purification chamber has, from top to bottom, a smokeless coal filter layer, a quartz sand filter layer, a manganese sand filter layer, and an inner electrolytic packing layer. The height of the connection point between the output end of the second water pump and the filtration purification chamber is higher than that of the smokeless coal filter layer. A third water pump is fixedly installed at the bottom of the filtration purification chamber, and the output end of the third water pump is connected to the water storage chamber. A purified water discharge pipe is provided at the bottom of the water storage chamber forming the purified water outlet.

[0021] In this optimized wastewater purification scheme, the wastewater is first reacted and filtered with chemical additives in a reaction purification chamber. Then, a second pump sends the purified wastewater to a filtration purification chamber. First, an anthracite filter layer removes large suspended solids and colloids, increasing the interception capacity and extending the filtration cycle. Next, a quartz sand filter layer removes fine impurities and reduces turbidity. Then, a manganese sand filter layer removes iron and manganese. Finally, an internal electrolytic packing layer degrades micro-pollutants in the wastewater, completing the purification process. The purified water is then pumped to a storage chamber for reuse. This wastewater treatment pond optimizes the wastewater treatment process and improves the quality of wastewater purification.

[0022] The beneficial effects of this invention are as follows: 1. When the dust collector performs preliminary filtration of exhaust gas, organic particulate matter and impurities such as activated carbon in the exhaust gas are adsorbed on the dust collector bags after being filtered by the multi-row bag assembly. The lifting plate of the lifting mechanism drives the horizontal connecting plate to move upward, thereby enabling the corresponding dust cleaning components of the multi-row bag assembly to perform dust cleaning operations simultaneously, reducing the number of lifting mechanisms, reducing energy consumption, and saving costs. When the horizontal connecting plate drives the lifting plate to rise, it causes the slip ring to slide upwards to scrape the lower part of the dust collector bag where there is more dust accumulation, ensuring the cleaning effect on the lower part. At the same time, the lifting plate also drives the linkage of the upper and lower linkage mechanisms, so that the two beaters move away from each other. After the lifting plate rises a certain distance, it quickly descends and resets under its own weight, causing the two beaters to move closer together and reset to beat the upper part of the dust collector bag, causing impurities to fall off further. When the lifting plate of the dust removal component rises, it scrapes the lower part of the dust collector bag; when the lifting plate descends, it beats the upper part of the dust collector bag. Combined with the pulse blower in the existing technology, the dust collector bag is blown. Through the multi-functional combination of scraping, beating and blowing, the cleaning effect of impurities on the bag is greatly enhanced, the filtration effect of the dust collector bag is guaranteed, and the dust removal and purification efficiency of the exhaust gas is improved.

[0023] 2. The exhaust gas undergoes secondary purification treatment through a dust collector and an exhaust gas spray tower, thereby purifying the organic harmful impurities and odors in the exhaust gas to meet emission standards.

[0024] The wastewater sprayed in the exhaust gas scrubbing tower is transported to the wastewater treatment tank via the sixth pipeline for purification. The purified water, after treatment in the wastewater treatment tank, is then transported back to the exhaust gas scrubbing tower via the seventh pipeline for further spraying. This structure achieves wastewater recycling, avoids resource waste, and improves the company's economic efficiency.

[0025] 3. Wastewater undergoes preliminary filtration through a primary wastewater filter to remove larger impurities and debris, preventing clogging and deposition in subsequent equipment. A gas-liquid separator separates the pre-filtered wastewater into waste gas, achieving separate treatment of waste gas and wastewater. The wastewater then enters a wastewater treatment tank for purification, resulting in purified water that meets discharge requirements.

[0026] 4. When purifying wastewater in the waste gas treatment tank, the wastewater is first reacted and filtered by stirring chemical additives in the reaction purification chamber. Then, a second water pump sends the purified wastewater to the filtration purification chamber. First, an anthracite filter layer traps large suspended solids and colloids, increasing the interception capacity and extending the filtration cycle. Next, a quartz sand filter layer removes fine impurities and reduces the turbidity of the wastewater. Then, a manganese sand filter layer removes iron and manganese. Finally, an internal electrolytic packing layer degrades micro-pollutants in the wastewater to complete the purification process. The purified water is then pumped to a storage chamber for reuse. This wastewater treatment tank optimizes the wastewater treatment process and improves the quality of wastewater purification. Attached Figure Description

[0028] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0029] like Figures 1-12 As shown, a wastewater treatment system based on exhaust gas purification function includes a wastewater pre-filter 200, the outlet of the wastewater pre-filter 200 is connected to a gas-liquid separator 12, the outlet of the gas-liquid separator 12 is connected to a wastewater treatment tank 300 for purifying wastewater, and the outlet of the gas-liquid separator 12 is connected to a dust collector 100 for purifying exhaust gas. The dust collector 100 is used to filter and purify the exhaust gas.

[0030] like Figure 1 As shown, specifically, the outlet of the wastewater primary filter 200 is connected to the inlet of the gas-liquid separator 12 through the first pipeline 11, and the wastewater primary filter 200 has a filter plate 203 for preliminary filtration of wastewater.

[0031] like Figure 2 As shown, the wastewater pre-filter 200 in this embodiment includes a filter box 201. A wastewater inlet pipe 202 is located at the top of the filter box 201, receiving the wastewater to be treated. A wastewater outlet pipe 204 is located at the bottom of the filter box 201, forming the outlet of the wastewater pre-filter 200. The pre-filtered wastewater is discharged from the wastewater outlet pipe 204. A horizontal filter plate 203 is fixedly connected inside the filter box 201. A first cleaning port 205 is opened on the side wall of the filter box 201, corresponding to the upper part of the filter plate 203. A first sealing cover 206 is installed on the first cleaning port 205. Larger impurities and debris in the wastewater are filtered through the filter plate 203, preventing clogging and deposition in subsequent equipment. The first cleaning port 205 allows for periodic cleaning of impurities on the filter plate 203, making it convenient to use.

[0032] like Figure 1 As shown, specifically, the outlet of the gas-liquid separator 12 is connected to the wastewater inlet of the wastewater treatment tank 300 via a second pipeline 13. The wastewater treatment tank 300 is used to purify wastewater. The gas-liquid separator 12 is used to separate waste gas from the wastewater. The wastewater, after being pre-filtered by the wastewater pre-filter 200, enters the gas-liquid separator 12. The separated wastewater is discharged from the outlet of the gas-liquid separator 12, and the separated waste gas is discharged from the outlet of the gas-liquid separator 12. The gas-liquid separator 12 is existing technology and will not be described in detail here.

[0033] like Figure 3 As shown, the wastewater treatment tank 300 in this embodiment includes a tank body 301. Two vertical partitions 302 are fixedly connected inside the tank body 301, and the two vertical partitions 302 are parallel and opposite to each other. The two vertical partitions 302 divide the tank body 301 into a reaction purification chamber 303, a filtration purification chamber 304, and a water storage chamber 305. The reaction purification chamber 303, the filtration purification chamber 304, and the water storage chamber 305 are arranged in a horizontal direction.

[0034] The reaction purification chamber 303 is equipped with a wastewater inlet pipe 306 to form the wastewater inlet. A feeding pipe 307 for adding chemical additives is located at the top of the reaction purification chamber 303. An agitator 308 for stirring the wastewater is located inside the reaction purification chamber 303. A second water pump 309 is fixedly installed at the bottom of the reaction purification chamber 303, and the output end of the second water pump 309 is connected to the filtration purification chamber 304. The filtration purification chamber 304 contains, from top to bottom, an anthracite filter layer 311, a quartz sand filter layer 312, a manganese sand filter layer 313, and an inner electrolytic packing layer 314. The height of the connection point between the output end of the second water pump 309 and the filtration purification chamber 304 is higher than that of the anthracite filter layer 311. A third water pump 317 is fixedly installed at the bottom of the filtration purification chamber 304, and the output end of the third water pump 317 is connected to a water storage chamber 305. A purified water discharge pipe 318 is located at the bottom of the water storage chamber 305 to form the purified water outlet.

[0035] In this embodiment, the stirrer 308 includes a geared motor, a vertical stirring shaft, and multiple horizontal stirring rods. The geared motor is fixed to the top of the reaction purification chamber 303. The stirring shaft is located inside the reaction purification chamber 303, and its upper end is connected to the output end of the geared motor. The multiple horizontal stirring rods are evenly distributed on the outer wall of the stirring shaft. The geared motor drives the stirring shaft to rotate, which in turn drives the stirring rods to rotate and perform stirring.

[0036] In this embodiment, the anthracite filter layer 311, quartz sand filter layer 312, manganese sand filter layer 313, and inner electrolytic packing layer 314 are all filter plate 203 structures, and are detachably installed in the filtration and purification chamber 304 for easy disassembly and replacement. A second cleaning port 315 is provided at the top of the filtration and purification chamber 304, and a second sealing cover 316 is installed on the second cleaning port 315. By opening the second sealing cover 316, the internal filter layers can be disassembled and replaced through the second cleaning port 315, facilitating operation.

[0037] In this embodiment, a water distribution plate 310 is installed inside the filtration and purification chamber 304 and above the anthracite filter layer 311. The water distribution plate 310 is detachably installed in the filtration and purification chamber 304, and multiple drain outlets are evenly distributed at the bottom of the water distribution plate 310. The output end of the second water pump 309 is connected to the inlet of the water distribution plate 310. Wastewater is evenly sprayed downwards through the water distribution plate 310, allowing the wastewater to fully contact the filter layer for filtration and improving the filtration effect. The water distribution plate 310 is prior art and will not be described in detail further.

[0038] The wastewater separated by the gas-liquid separator 12 is purified by the wastewater treatment tank 300 to become purified water. The purified water is stored in the water storage chamber 305 for use or discharged to the outside.

[0039] like Figure 1As shown, specifically, the outlet of the gas-liquid separator 12 is connected to the inlet of the dust collector 100 via a third pipe 14, and an activated carbon injector 7 is also connected to the third pipe 14. The activated carbon injector 7 is used to inject activated carbon, which is existing technology. The injection pipe of the activated carbon injector 7 is connected to the third pipe 14. The waste gas separated by the gas-liquid separator 12 enters the dust collector 100 for filtration through the third pipe 14, and when the waste gas passes through the third pipe 14, the activated carbon injector 7 injects activated carbon into the third pipe 14, so that the activated carbon comes into contact with the waste gas, and the activated carbon adsorbs the odor and organic particles in the waste gas. Then, the dust collector 100 filters the suspended matter, dust and adsorbed activated carbon in the waste gas, realizing the preliminary filtration and purification of the waste gas.

[0040] like Figure 9 As shown, the dust collector 100 in this embodiment includes a dust collector body 1. A partition 3 is fixedly installed inside the dust collector body 1. Multiple rows of filter bag groups 2 are arranged and fixedly installed at the bottom of the partition 3 in a horizontal direction. Each row of filter bag groups 2 includes multiple dust collector bags 21 arranged in a longitudinal direction. Each row of filter bag groups 2 is provided with a dust cleaning component 4 for simultaneously cleaning multiple dust collector bags 21.

[0041] like Figure 4 As shown, specifically, the partition 3 divides the dust collector body 1 into an upper cavity and a lower cavity. A horizontal smoke inlet pipe 6 is fixedly connected to the outer wall of the dust collector body 1, forming the air inlet end of the dust collector. The smoke inlet pipe 6 communicates with the lower cavity of the dust collector body 1, and the exhaust gas enters the lower cavity of the dust collector body 1 through the smoke inlet pipe 6 for preliminary filtration. An exhaust pipe 10 is also fixedly connected to the outer wall of the dust collector body 1, forming the air outlet end of the dust collector. The exhaust pipe 10 communicates with the upper cavity of the dust collector body 1.

[0042] The dust collector bag 21 is fixed to the bottom of the partition plate 3. The inner cavity of the dust collector bag 21 is connected to the upper cavity of the dust collector body 1. The dust collector bag 21 filters organic particulate impurities and adsorbed activated carbon in the exhaust gas. The filtered impurities are attached to the outer wall of the dust collector bag 21. The filtered exhaust gas enters the upper cavity of the dust collector body 1 through the inner cavity of the dust collector bag 21 and is discharged from the exhaust pipe 10 by the fan.

[0043] like Figure 4 , 6 As shown, the top of the dust collector body 1 is also equipped with multiple sets of pulse blowers 9. Each set of pulse blowers 9 corresponds to a row of filter bags 2. Each pulse blower 9 has multiple air pipes 91, which correspond one-to-one with multiple filter bags 21 in the filter bag group 2. The lower end of each air pipe 91 is inserted into the inner cavity of the filter bag 21. This structure is a conventional technology in existing dust collectors and will not be described in detail again. The impurities adhering to the outer wall of the filter bags are cleaned by back-blowing the filter bags 21 with the pulse blowers 9.

[0044] like Figure 6 As shown, specifically, the dust removal component 4 includes a lifting plate 41 located below the bag assembly 2, and two beating rods 42 symmetrically distributed on both sides of the bag assembly 2. The lifting plate 41 and the beating rods 42 both extend along the arrangement direction of the plurality of dust collector bags 21.

[0045] Multiple sets of upper linkage mechanisms 43 are provided between the partition 3 and the two striking rods 42, and these upper linkage mechanisms 43 are arranged along the length of the striking rods 42. Each upper linkage mechanism 43 includes two upper connecting rods 431, the lower ends of which are hinged to the two striking rods 42, and the upper ends of which are hinged to the partition 3. The distance between the upper ends of the two upper connecting rods 431 is less than the distance between their lower ends. In this embodiment, two sets of upper linkage mechanisms 43 are distributed along the length of the striking rods 42, located at both ends of the striking rods 42. First fixing plates are fixed to the bottom of the partition 3 and the top of the striking rods 42. The upper and lower ends of the upper connecting rods 431 are hinged to the two first fixing plates, facilitating installation.

[0046] Multiple sets of lower linkage mechanisms 48 are provided between the lifting plate 41 and the two striking rods 42, and the multiple sets of lower linkage mechanisms 48 are arranged along the length direction of the striking rods 42. The lower linkage mechanism 48 includes two lower connecting rods 481, the upper ends of the two lower connecting rods 481 are respectively hinged to the two striking rods 42, and the lower ends of the two lower connecting rods 481 are both hinged to the lifting plate 41, and the distance between the lower ends of the two lower connecting rods 481 is smaller than the distance between the upper ends of the two lower connecting rods 481. In this embodiment, two sets of lower linkage mechanisms 48 are distributed along the length direction of the striking rods 42, and the two sets of lower linkage mechanisms 48 are located at both ends of the striking rods 42. The top of the lifting plate 41 and the bottom of the striking rods 42 are both fixedly connected to second fixing plates, and the upper and lower ends of the lower connecting rods 481 are respectively hinged to the two second fixing plates for easy installation.

[0047] In this embodiment, the axes of symmetry of the two upper connecting rods 431, the axes of symmetry of the two lower connecting rods 481, and the axes of symmetry of the two striking rods 42 are the same axis.

[0048] like Figure 11 As shown, the dust collector body 1 is also equipped with a lifting mechanism 5 that drives the lifting plate 41 to move upward. Since the distance between the upper ends of the two lower connecting rods 481 is greater than the distance between the lower ends, and the distance between the lower ends of the two upper connecting rods 431 is greater than the distance between the upper ends, when the lifting plate 41 rises, it will drive the two lower connecting rods 481 and the two upper connecting rods 431 to spread outward, thereby driving the two beating rods 42 to move away from each other. When the lifting plate 41 falls, it will drive the two beating rods 42 to move closer to each other and beat the dust collector bag 21, causing the impurities adhering to the dust collector bag to fall off, thus improving the cleaning effect of impurities.

[0049] like Figure 4 , 9 As shown in Figure 10, specifically, the dust removal assembly 4 also includes a slip ring 44 fitted onto the bottom of the dust collector bag 21. The inner wall of the slip ring 44 is provided with a cleaning brush 46 that contacts the outer wall of the dust collector bag 21. The slip ring 44 is fixedly connected to the lifting plate 41 via a vertical connecting rod 45. In this embodiment, the slip ring 44 is fitted onto multiple dust collector bags 21 of the bag assembly 2. When the lifting plate 41 rises, it can simultaneously drive the slip ring 44 to slide upward. Since the slip ring 44 is located at the bottom of the dust collector bag 21, when the slip ring 44 rises, it scrapes the lower part of the dust collector bag 21 through the cleaning brush 46, preventing impurities at the bottom of the dust collector bag from clumping together and affecting the filtration effect of the dust collector bag.

[0050] When cleaning particulate matter, activated carbon, and other impurities from the dust collector bag 21, the lifting plate 41 rises, causing the slip ring 44 to scrape the lower part of the dust collector bag 21 upwards. When the lifting plate 41 descends, it causes the two beaters 42 to beat the dust collector bag 21. At the same time, the pulse blower 9 blows the dust collector bag 21. This combination of scraping, beating, and blowing greatly enhances the cleaning effect of impurities, ensures the filtration effect of the dust collector bag 21, and improves the dust removal and purification efficiency of the exhaust gas.

[0051] like Figure 9 As shown, preferably, the lifting plates 41 of the dust removal components 4 of the multi-row bag assembly 2 are fixedly connected as a whole by transverse connecting plates 47 extending laterally, and the lifting mechanism 5 drives the transverse connecting plates 47 to move upward. In this embodiment, transverse connecting plates 47 are provided on both longitudinal sides of the bag assembly 2, and the two ends of the multiple lifting plates 41 are respectively fixedly connected to two transverse connecting plates 47. By connecting the lifting plates 41 of the multiple dust removal components 4 into a whole by two transverse connecting plates 47, all lifting plates 41 can move synchronously by driving the transverse connecting plates 47. It is not necessary to set a lifting mechanism 5 for each dust removal component 4, which reduces the number of lifting mechanisms 5 used, reduces energy consumption, and saves costs.

[0052] In this embodiment, both ends of the horizontal connecting plate 47 are provided with the lifting mechanism 5. One horizontal connecting plate 47 moves upward driven by two lifting mechanisms 5, resulting in greater stability. By driving two horizontal connecting plates 47 to rise synchronously through four lifting mechanisms 5, multiple lifting plates 41 can rise synchronously, making the overall movement more stable.

[0053] like Figure 5 , 7As shown, specifically, the lifting mechanism 5 includes a drive sprocket 51, a driven sprocket 52, a chain 53, a lifting block 55, and a drive motor 54. The drive sprocket 51 and the driven sprocket 52 are vertically distributed and rotatably connected to the dust collector body 1. The drive motor 54 drives the drive sprocket 51 to rotate. In this embodiment, the drive motor 54 is fixed to the outer wall of the dust collector body 1, and the output end of the drive motor 54 is fixedly connected to the drive sprocket 51, thereby driving the rotation of the drive sprocket. The drive sprocket 51 and the driven sprocket 52 are connected by the chain 53. The lifting block 55 is fixed to the outside of the chain 53, and when the lifting block 55 rises, it contacts the horizontal connecting plate 47.

[0054] In this embodiment, the horizontal height of the upper end of the chain 53 is not higher than the horizontal height of the bottom of the dust collector bag 21. This ensures that when the lifting block 55 raises the horizontal connecting plate 47 to its highest point, the lifting plate 41 will not contact the bottom of the dust collector bag 21, thus preventing the lifting plate 41 from bumping into the dust collector bag 21. In this embodiment, the lifting block 55 has a cylindrical structure, and the bottom surface of the end of the horizontal connecting plate 47 has an arc-shaped groove 471 that mates with the lifting block 55. When the lifting block 55 rises to the upper end of the chain 43, it slides outward along the arc-shaped groove 471, facilitating its disengagement.

[0055] In this embodiment, the drive motors 54 of the lifting mechanisms located at both ends of the horizontal connecting plate 47 rotate in opposite directions, while the drive motors 54 of the lifting mechanisms located at the same end of the two horizontal connecting plates 47 rotate in the same direction, thereby achieving synchronous lifting of the two horizontal connecting plates 47.

[0056] The lifting mechanism 5 drives the drive sprocket 51 to rotate via the drive motor 54. The drive sprocket 51 drives the driven sprocket 52 to rotate via the chain 53. During the transmission process, the chain 53 drives the lifting block 55 to move circumferentially along the chain 53. During the upward movement, the lifting block 55 contacts the arc-shaped groove 471 at the end of the horizontal connecting plate 47, thereby driving the horizontal connecting plate 47 to move upward. In turn, the slip ring 44 scrapes the lower part of the dust collector bag 21 upward. When the lifting block 55 rises to the upper end of the chain 53, the lifting block 55 slides outward and disengages from the horizontal connecting plate 47. At this time, the horizontal connecting plate 47 and the lifting plate 41 will quickly descend and reset under their own weight, causing the two striking rods 42 to move closer to each other and strike the dust collector bag 21. After the chain 53 rotates one revolution, the lifting block 55 contacts the arc-shaped groove 471 at the end of the horizontal connecting plate 47 again. This cycle allows the dust removal assembly 4 to continuously scrape and strike the dust collector bag 21, ensuring the removal of impurities.

[0057] like Figure 8As shown, preferably, to further improve the stability of the lifting plate 41 during its upward movement, the horizontal connecting plate 47 is provided with several support components 8 distributed along its length. In this embodiment, two support components 8 are evenly distributed along the length of the horizontal connecting plate 47. Each support component 8 includes a guide wheel 81 rotatably connected to the horizontal connecting plate 47, and a C-shaped guide rail 82 fixed to the inner wall of the dust collector body 1. The C-shaped guide rail 82 extends vertically, with its bottom closed. The guide wheel 81 rolls along the C-shaped guide rail 82, and the outer diameter of the guide wheel 81 matches the inner diameter of the C-shaped guide rail 82.

[0058] The horizontal connecting plate 47 moves up and down along the C-shaped guide rail 82 via the guide wheel 81, improving stability during movement and preventing swaying. Simultaneously, the closed bottom of the C-shaped guide rail 82 supports the guide wheel 81, thus supporting the entire dust removal assembly 4. The lifting plate 41 descends under its own weight, causing the guide wheel 81 to roll down to the bottom of the C-shaped guide rail 82 and stop. At this point, the lifting plate 41 also stops descending, thus positioning the descent distance of the lifting plate 41.

[0059] In this embodiment, a shock-absorbing pad 83 is fixed to the inner bottom of the C-shaped guide rail 82. The shock-absorbing pad 83 buffers the descent of the guide wheel 81 and reduces vibration.

[0060] In general, the dust collector 100 filters organic particulate matter and activated carbon impurities in the exhaust gas through the multi-row bag assembly 2, which are then adsorbed onto the dust collector bags 21. The lifting plate 41 of the lifting mechanism 5 drives the horizontal connecting plate 47 upwards, causing the corresponding dust cleaning components 4 of the multi-row bag assembly 2 to perform simultaneous dust cleaning. When the horizontal connecting plate 47 drives the lifting plate 41 upwards, it causes the slip ring 44 to slide upwards, scraping the lower part of the dust collector bags 21 where there is more accumulated dust, ensuring effective cleaning of the lower part. Simultaneously, the upward movement of the lifting plate 41 also drives the linkage of the upper connecting rod mechanism 43 and the lower connecting rod mechanism 48, causing the two striking rods 42 to move away from each other. After the lifting plate 41 rises a certain distance, it quickly descends and resets under its own weight, causing the two striking rods 42 to move closer together and strike the upper part of the dust collector bags 21, further dislodging impurities. When the lifting plate 41 of the dust removal component 4 rises, it scrapes the lower part of the dust collector bag 21. When the lifting plate 41 falls, it beats the upper part of the dust collector bag 21. In addition, the pulse blower 9 in the prior art blows the dust collector bag 21. Through the multi-functional combination of scraping, beating and blowing, the cleaning effect of impurities is greatly enhanced, and the filtration effect of the dust collector bag 21 is guaranteed.

[0061] like Figure 1As shown, specifically, the outlet of the dust collector is connected to a fan. In this embodiment, the outlet of the dust collector 100 is connected to the input of the fan 16 via the fourth pipe 15. The output of the fan is connected to an exhaust gas spray tower. In this embodiment, the output of the fan 16 is connected to the inlet of the exhaust gas spray tower 400 via the fifth pipe 17. The exhaust gas spray tower 400 is used for secondary purification of exhaust gas.

[0062] The spray water output end of the exhaust gas scrubbing tower 400 is connected to the wastewater input end of the wastewater treatment tank 300 via a sixth pipeline 18, and a first valve 19 and a one-way valve 500 are sequentially installed on the sixth pipeline 18 along the conveying direction. A water pump may also be installed on the sixth pipeline 18 for pumping wastewater. The purified water output end of the wastewater treatment tank 300 is connected to the spray water input end of the exhaust gas scrubbing tower 400 via a seventh pipeline 600, and a second valve 700 and a first water pump 800 are sequentially installed on the seventh pipeline 600 along the conveying direction.

[0063] The pre-purified exhaust gas is drawn into the exhaust gas scrubbing tower 400 by the fan 16 for secondary scrubbing purification, thereby removing organic harmful impurities and odors from the exhaust gas to meet emission standards. The wastewater from the exhaust gas scrubbing tower 400 is then transported to the wastewater treatment tank 300 for further purification via the sixth pipeline 18. The purified water from the wastewater treatment tank is then returned to the exhaust gas scrubbing tower 400 via the seventh pipeline 600 for further scrubbing. This structure achieves wastewater recycling, avoids resource waste, and improves the company's economic efficiency.

[0064] like Figure 1 As shown, in this embodiment, the spray water output end of the exhaust gas spray tower 400 is also connected to an eighth pipe 900, and a third valve 901 is installed on the eighth pipe 900. In this embodiment, the spray water output end of the exhaust gas spray tower 400, the sixth pipe 18, and the eighth pipe 900 are connected by a tee. The wastewater after spraying can be transported to the wastewater treatment tank 300 for purification treatment through the sixth pipe 18, or discharged to the outside or other treatment equipment for treatment through the eighth pipe 900, which is convenient to use.

[0065] like Figure 1As shown, in this embodiment, the purified water output end of the wastewater treatment tank 300 is connected to the spray water input end of the exhaust gas spray tower 400 via a seventh pipe 600. A second valve 700 and a first water pump 800 are sequentially installed on the seventh pipe 600 along the conveying direction. The purified water output end of the wastewater treatment tank 300 is also connected to a ninth pipe 902, on which a fourth valve 903 is installed. In this embodiment, the purified water output end of the wastewater treatment tank 300, the seventh pipe 600, and the ninth pipe 902 are connected via a tee. The purified water treated by the wastewater treatment tank 300 can be transported back to the exhaust gas spray tower 400 for spraying operations via the seventh pipe 600, or discharged to the outside environment via the ninth pipe 902 or utilized in other ways, making its use more flexible.

[0066] like Figure 12 As shown, the exhaust gas scrubbing tower 400 of this embodiment includes a tower body 401, with a gas exhaust pipe 402 at the top. An exhaust gas filter media layer 405 is provided inside the tower body 401. In this embodiment, the exhaust gas filter media layer 405 can be corrugated packing or grid packing, both of which are commonly used in existing scrubbing towers and have stable and good filtration effects. A spray pipe 406 is fixed above the exhaust gas filter media layer 405, and several spray heads are evenly distributed at the bottom of the spray pipe 406. One end of the spray pipe 406 extends to the outside of the tower body 401 to form the spray water inlet. An exhaust gas inlet pipe 403 is provided on the side wall of the tower body 401 to form the air inlet of the exhaust gas scrubbing tower 400. The height of the exhaust gas inlet pipe 403 is lower than the height of the exhaust gas filter media layer 405, and a spray water outlet pipe 404 is provided at the bottom of the tower body 401 to form the spray water outlet. In this embodiment, two layers of waste gas filter packing 405 are arranged from top to bottom inside the tower body 401, and each layer of waste gas filter packing 405 is equipped with a spray pipe 406 above it. After the waste gas enters the waste gas spray tower 400, it flows upward and is purified by passing through the waste gas filter packing layer 405, further removing odors and organic particulate impurities from the waste gas. The spray pipe 406 sprays the packing layer to improve the reaction and purification effect. The purified waste gas is discharged into the atmosphere from the gas emission pipe 402 at the top.

[0067] The above-mentioned wastewater treatment system based on exhaust gas purification function is used in the following steps: S1. Wastewater is introduced into the wastewater primary filter 200 through the wastewater inlet pipe 202. Larger impurities and garbage in the wastewater are filtered through the filter plate 203 to prevent impurities from clogging and accumulating in subsequent equipment. S2. Wastewater discharged from the primary wastewater filter 200 enters the gas-liquid separator 12 for gas-liquid separation. The separated wastewater enters the wastewater treatment tank 300 for purification. The separated waste gas enters the dust collector 100 for preliminary purification through the third pipeline 14. S3. After the wastewater separated in step S2 enters the wastewater treatment tank 300, chemical additives (such as coagulants, disinfectants, etc.) are first added to the reaction purification chamber 303 through the feed pipe 307. The wastewater and chemical additives are stirred and reacted by the agitator 308 to carry out the purification reaction. Then, the second water pump 309 sends the purified wastewater to the filtration purification chamber 304. First, the anthracite filter layer 311 intercepts large particulate suspended solids and colloids, increasing the interception capacity and extending the filtration cycle. Then, the quartz sand filter layer 312 removes fine impurities and reduces the turbidity of the wastewater. Then, the manganese sand filter layer 313 removes iron and manganese. Finally, the internal electrolytic packing layer 314 degrades the micro pollutants in the wastewater to complete the purification. The purified water is then sent to the water storage chamber 305 for storage and utilization by the third water pump 317. S4. When the waste gas separated in step S2 passes through the third pipeline 14, activated carbon is injected into the third pipeline 14 through the activated carbon injector 7, so that the activated carbon comes into contact with the waste gas and adsorbs odors and most of the organic particulate impurities. Then, driven by the airflow of the fan 16, the waste gas and the adsorbed activated carbon enter the dust collector body 1 through the smoke inlet pipe 6. The dust collector bags 21 of the multi-row bag group 2 filter the organic particles, activated carbon and other impurities in the waste gas. The filtered impurities are attached to the dust collector bags 21, and the filtered waste gas enters the fan through the smoke exhaust pipe 10. The fan draws the waste gas to the waste gas spray tower 400 for secondary purification treatment. In steps S5 and S4, when the dust collector 100 is filtering, the pulse blower 9 is started to periodically blow the dust collector bag 21. The drive motor 54 of the lifting mechanism 5 is started to drive the drive sprocket 51 to rotate. The drive sprocket 51 drives the driven sprocket to rotate through the chain 53. During the transmission process of the chain 53, the lifting block 55 is driven to move circumferentially along the chain 53. During the upward process, the lifting block 55 contacts the horizontal connecting plate 47 and drives the horizontal connecting plate 47 to move upward, so that all the lifting plates 41 move upward synchronously. During the upward process of the lifting plates 41, the slip ring 44 is driven upward. The lifting plate 41 moves upward, and the cleaning brush 46 inside the slip ring 44 scrapes away the impurities adhering to the lower part of the dust collector bag 21, preventing the impurities from accumulating and clumping at the lower part of the dust collector bag, thus improving the filtration efficiency. At the same time, during the upward movement of the lifting plate 41, it also drives the two beating rods 42 to move away from each other. When the lifting block 55 moves to the upper end of the chain 53, it disengages from the horizontal connecting plate 47. At this time, the lifting plate 41 descends rapidly under its own weight, thereby driving the two beating rods 42 to move closer to each other and simultaneously beat the multiple dust collector bags 21 of the bag assembly, causing the impurities on the dust collector bags 21 to fall off further, thus improving the dust removal efficiency. In steps S6 and S5, after the chain 53 drives the lifting block 55 to rotate once, the lifting block 55 contacts the horizontal connecting plate 47 again and drives the horizontal connecting plate 47 to move upward, repeating the cycle.

[0068] In steps S7 and S4, when the exhaust gas discharged from the dust collector 100 enters the exhaust gas spray tower 400, it flows upward and reacts with the exhaust gas filter packing layer 405 to purify it, further removing odors and organic particulate impurities from the exhaust gas. At the same time, the purified water discharged from the purified water output end of the wastewater treatment tank 300 is transported to the spray pipe 406 by the first water pump 800 to spray the exhaust gas filter packing layer 405, improving the reaction purification effect. The purified exhaust gas is discharged to the atmosphere from the gas emission pipe 402 at the top. The sprayed wastewater is then transported back to the wastewater treatment tank 300 for purification treatment through the sixth pipeline 18, realizing the recycling of wastewater, avoiding resource waste, and improving the economic benefits of the enterprise.
