Description

Technical Field

[0001] This utility model relates to the field of oil stain cleaning, specifically to an oil removal filter backwashing device. Background Technology

[0002] In the chemical industry, filters are key equipment for purifying fluids and separating impurities, with their core component being the internal filter media. The filter media uses its porous structure to intercept solid particles, oil, and other impurities in the fluid, thereby ensuring the stability of subsequent processes and product quality.

[0003] However, during long-term use, a large amount of oily and sticky impurities will gradually adsorb and accumulate on the surface and within the pores of the filter media, leading to filter media blockage, decreased filtration efficiency, and increased energy consumption. If not cleaned in time, the filter media may even need to be replaced frequently due to failure, which not only increases production costs but also affects production continuity due to downtime for media replacement.

[0004] Existing technologies have long backwashing times, generate a lot of wastewater, and are not thorough in backwashing. Over time, this can cause filter blockage, clumping of the upper packing, a decrease in treatment load, an increase in effluent quality, increased filter media wear, and easy damage to filter internals.

[0005] Therefore, it is very necessary to provide an oil removal filter backwashing device to solve the above-mentioned technical problems. Utility Model Content

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An oil removal filter backwashing device includes a filter, an air cleaning component, a steam cleaning component, and a water washing component connected to the filter. The air cleaning component is used to use gas to flow in the tiny gaps between the filter media particles to flush the filter media in all directions, thereby removing most of the impurities from the filter media through air washing. The steam cleaning component is used to clean stubborn impurities in the filter with steam. The water washing component is used to clean the impurities in the filter by using the impact force and adsorption capacity of water.

[0008] Furthermore, the air cleaning component includes a pressure tank and an air pipe connected to the pressure tank. The air pipe is connected to the filter, and an air inlet valve is connected to the air pipe. A first electrically controlled vent valve is connected to the upper end of the filter. The first electrically controlled vent valve is used to release the internal air pressure of the filter during air cleaning.

[0009] Furthermore, the steam cleaning component includes a steam generator and a heater connected inside the steam generator. The heater is used to heat the water inside the steam generator so that the water absorbs heat and forms steam. A steam input pipe is connected to the steam generator and is connected to the filter. A steam inlet valve is connected to the steam input pipe, and a second electrically controlled vent valve is connected to the steam generator.

[0010] Furthermore, the steam cleaning component includes a liquid injection pump, one end of which is connected to a first liquid inlet pipe, which is connected to the steam generator, and the other end of which is connected to a second liquid inlet pipe, which is connected to a water source.

[0011] Furthermore, the steam generator is equipped with a liquid level sensor, which is used to detect the liquid level in the steam generator. When the liquid level in the steam generator reaches a preset minimum level, the sensor outputs a signal to control the liquid pump to start; when the liquid level in the steam generator reaches a preset maximum level, the sensor outputs a signal to control the liquid pump to stop.

[0012] Furthermore, the washing component includes a water inlet pump, one end of which is connected to a first water inlet pipe, which is connected to the filter, and the other end of which is connected to a second water inlet pipe, which is connected to a cleaning water source.

The other end of the water outlet observation tank is connected to a second water outlet conduit connected to a collection tank.

[0014] Furthermore, a first high-precision water pressure sensor is connected inside the first water inlet pipe, which is used to detect the water pressure inside the first water inlet pipe; a second high-precision water pressure sensor is connected inside the first water outlet pipe, which is used to detect the water pressure inside the first water outlet pipe.

[0015] Furthermore, a light irradiation unit is connected to one side of the water outlet observation tank, which is used to emit a light source towards the water outlet observation tank from the side; a side observation unit is connected to the other side of the water outlet observation tank, which is used by the user to observe the light irradiation unit; and an upper observation unit is connected to the upper side of the water outlet observation tank, which is used by the user to observe the water outlet observation tank from above.

[0016] Furthermore, the filter is connected to a feed pipe, which is connected to a feed valve, and the lower end of the filter is connected to a discharge pipe, which is connected to a discharge valve.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: By combining air cleaning, steam cleaning, and water washing components, comprehensive and deep cleaning of the filter media within the filter is achieved. The air cleaning component utilizes the flow of gas through the tiny gaps between filter media particles to thoroughly flush the media, efficiently and quickly removing most impurities from the surface, laying the foundation for subsequent deep cleaning. The steam cleaning component targets stubborn impurities within the filter, effectively softening and dissolving difficult-to-remove dirt through the high temperature and pressure of steam, further enhancing the thoroughness of the cleaning. The water washing component leverages the powerful impact and adsorption capacity of water to completely remove residual impurities, ensuring the filter media regains its optimal filtration performance, significantly improving filtration efficiency and quality. This solution addresses the problems of existing technologies, such as long backwashing times, excessive wastewater generation, incomplete backwashing, filter clogging over time, upper packing material agglomeration, decreased processing load, increased effluent quality, increased filter media wear, and easy damage to filter internal components.

[0025] like Figures 1 to 7 As shown, an oil removal filter backwashing device includes a filter 1, an air cleaning component 2, a steam cleaning component 3, and a water washing component 4 connected to the filter 1. The air cleaning component 2 is used to use gas to flow in the tiny gaps between the filter media particles to flush the filter media from all directions, thereby removing most of the impurities from the filter media through air washing. The steam cleaning component 3 is used to clean stubborn impurities in the filter 1 with steam. The water washing component 4 is used to clean the impurities in the filter 1 by using the impact force and adsorption capacity of water.

[0026] In this embodiment, the synergistic action of the air cleaning component 2, the steam cleaning component 3, and the water washing component 4 achieves comprehensive and deep cleaning of the filter media inside the filter 1. The air cleaning component 2 utilizes the flow of gas through the tiny gaps between the filter media particles to thoroughly flush the filter media, efficiently and quickly removing most impurities from the surface of the filter media, laying the foundation for subsequent deep cleaning. The steam cleaning component 3 targets stubborn impurities inside the filter 1, effectively softening and dissolving difficult-to-remove dirt through the high temperature and high pressure characteristics of steam, further improving the thoroughness of the cleaning. The water washing component 4 utilizes the powerful impact and adsorption capacity of water to thoroughly remove residual impurities, ensuring that the filter media inside the filter 1 restores its optimal filtration performance, significantly improving filtration efficiency and quality.

[0027] Step 1: Optimize the original production line by improving the air washing effect of filter 1. Increase the air washing time from 5 minutes to 20 minutes to thoroughly loosen the filter media layer and shake off stubborn impurities. The gas flows through the tiny gaps between the filter media particles, thoroughly washing the media. By removing most of the impurities from the filter media through air washing, the subsequent water washing time can be shortened and the water consumption reduced. Step 2: Add a steam cleaning process. The steam cleaning time is 15 to 20 minutes. This will soften stubborn impurities that have not been removed by the steam cleaning process at high temperature, reducing the time and water consumption for subsequent water washing. Step 3: The backwashing process has been changed from the previous 30 minutes to observing the water quality by taking samples during the backwashing process. If the effluent is clear and transparent to the naked eye, without obvious turbidity or abnormal color, and has no odor, it indicates that the filter media has been cleaned and the backwashing is complete. Through optimization, the backwashing time is generally 15-20 minutes, shortening the washing time, reducing water consumption, and decreasing wastewater generation. Step 4: Simultaneously, the forward rinse time has been changed from 30 minutes to observing that the water quality meets standards, the flow rate is stable, and the inlet / outlet pressure difference drops to approximately 0.01 MPa, at which point the forward rinse is complete. Through optimization, the forward rinse time is generally 10 minutes. Step 5: This application changes the original backwashing frequency from once every 24 hours to backwashing when the inlet and outlet pressure difference rises to 0.05-0.0 MPa, thus reducing the backwashing frequency.

[0028] In some embodiments, the air cleaning component 2 includes a pressure tank 21 and an air inlet pipe 22 connected to the pressure tank 21. The air inlet pipe 22 is connected to the filter 1, and an air inlet valve 23 is connected to the air inlet pipe 22. A first electrically controlled vent valve 24 is connected to the upper end of the filter 1. The first electrically controlled vent valve 24 is used to release the internal air pressure of the filter 1 when the filter 1 is air-washed.

[0029] In this embodiment, the air inlet valve 23 is installed on the air inlet pipe 22, which can precisely control the on / off state and flow rate of the gas. The operator can flexibly adjust the amount of gas entering the filter according to the actual degree of contamination and cleaning needs of the filter 1, thereby achieving the best air washing effect and avoiding gas waste and excessive impact that could damage the filter material.

[0030] The first electrically controlled vent valve 24 is connected to the upper end of the filter 1 and plays a crucial role in safety and pressure regulation during the air washing process. When air washing is performed on the filter 1, the internal air pressure gradually increases as gas is continuously injected. The first electrically controlled vent valve 24 can monitor the internal air pressure of the filter in real time and automatically open when the air pressure reaches the set value, releasing the internal air pressure in a timely manner to prevent damage to the filter 1 due to excessive air pressure, such as filter shell cracking or filter media displacement, thus ensuring the safety and stability of the air washing process. Simultaneously, by reasonably controlling the venting process, the internal air pressure of the filter can be maintained within a certain range, making the gas flow between the filter media particles more uniform and stable, further improving the air washing effect, effectively removing most impurities from the filter media, and providing a good foundation for subsequent steam cleaning and water washing, thereby improving the performance and reliability of the entire filter cleaning system.

[0031] In addition, based on actual usage, a pressure sensor is connected to the upper end of filter 1 to detect pressure changes within filter 1 in real time, which should also fall within the scope of protection of this application. The specific model, structure, and connection method of the pressure sensor are well known to those skilled in the art, and will not be elaborated here.

[0032] In some embodiments, the steam cleaning component 3 includes a steam generator 31 and a heater 32 connected inside the steam generator 31. The heater 32 is used to heat the water inside the steam generator 31 so that the water absorbs heat to form steam. A steam input pipe 33 is connected to the steam generator 31 and is connected to the filter 1. A steam inlet valve 34 is connected to the steam input pipe 33, and a second electrically controlled vent valve 35 is connected to the steam generator 31.

[0033] In this embodiment, a temperature sensor is installed in the steam generator 31 to detect the real-time temperature, and a temperature controller is also installed. The temperature control function ensures that the steam temperature is kept stable within a suitable range, which can effectively soften and dissolve stubborn dirt in the filter 1 without damaging the material of the filter 1 due to excessive temperature, thus ensuring the safety and effectiveness of the cleaning process.

[0034] The steam inlet valve 34 is installed on the steam inlet pipe 33 and serves to control the steam on / off state and flow rate. Operators can flexibly adjust the steam inlet valve 34 according to the degree of contamination and cleaning stage of the filter 1 to control the amount of steam entering the filter 1. This improves steam utilization, reduces energy waste, and avoids excessive impact on the filter media due to excessive steam flow, thus extending the service life of the filter media.

[0035] The second electrically controlled vent valve 35 is connected to the steam generator 31, providing crucial safety assurance for the entire steam cleaning system. During steam generation, the pressure gradually increases as steam is continuously produced and accumulated within the tank. A pressure sensor is installed inside the steam generator 31 to monitor the pressure in real time. When the pressure exceeds a set safety value, the second electrically controlled vent valve 35 automatically opens to release pressure, preventing dangerous accidents such as explosions caused by excessive pressure in the steam generator 31, thus ensuring the safety of the equipment and operators. Furthermore, after cleaning, the second electrically controlled vent valve 35 can promptly discharge any remaining steam from the tank, facilitating equipment maintenance and repair.

[0036] In some embodiments, the steam cleaning component 3 includes a liquid inlet pump 36, one end of which is connected to a first liquid inlet pipe 37, which is connected to the steam generator 31, and the other end of which is connected to a second liquid inlet pipe 38, which is connected to a water source.

[0037] In this embodiment, the liquid pump 36 can stably and continuously deliver water from the water source to the steam generator 31 in a precise manner according to a preset program and parameters. This precise liquid delivery method ensures a stable supply of water in the steam generator 31, avoiding interruptions in steam generation due to insufficient water, which would affect the continuity of the cleaning process.

[0038] The first inlet pipe 37 and the second inlet pipe 38 are made of high-quality corrosion-resistant materials, possessing excellent sealing and pressure resistance. They can withstand the pressure generated when the liquid pump 36 delivers liquid and effectively prevent water leakage during transmission, ensuring the high efficiency and reliability of liquid transmission.

[0039] In some embodiments, the steam generator 31 is provided with a liquid level sensor 39, which is used to detect the liquid level in the steam generator 31. When the liquid level in the steam generator 31 reaches a preset minimum level, the sensor outputs a signal to control the liquid pump 36 to start; when the liquid level in the steam generator 31 reaches a preset maximum level, the sensor outputs a signal to control the liquid pump 36 to stop.

[0040] In this embodiment, when the liquid level in the steam generator 31 drops to a preset minimum level, the liquid level sensor 39 quickly outputs a signal to trigger the liquid replenishment pump 36 to start. This control mechanism effectively prevents the steam generator 31 from drying out due to excessively low liquid levels. Dry burning not only damages the heating element of the steam generator 31 and shortens the equipment's lifespan, but may also cause safety accidents such as fires. By replenishing water in a timely manner, the continuity and stability of the steam generation process are ensured, guaranteeing the normal progress of the cleaning work.

[0041] When the liquid level in the steam generator 31 rises to the preset maximum level, the liquid level sensor 39 immediately outputs a signal to control the liquid supply pump 36 to shut down. This design prevents abnormal pressure increases in the steam generator 31 due to excessive liquid level, avoiding equipment damage caused by excessive pressure and further enhancing the system's safety and reliability. Simultaneously, reasonable liquid level control can optimize water resource utilization, avoid water waste, and reduce equipment operating costs.

[0042] In some embodiments, the washing component 4 includes a water inlet pump 41, one end of which is connected to a first water inlet pipe 42, which is connected to the filter 1, and the other end of which is connected to a second water inlet pipe 43, which is connected to a cleaning water source.

[0043] In this embodiment, the first water inlet pipe 42 and the second water inlet pipe 43 are made of high-quality materials and have a reasonable structural design. They have good corrosion resistance and sealing performance, can withstand the pressure generated when the water pump 41 delivers water, and effectively prevent water leakage during transmission. This not only ensures a stable supply of cleaning water and reduces water waste, but also avoids the impact on the surrounding environment caused by pipe leakage.

[0044] In some embodiments, the washing component 4 includes a water outlet observation tank 44, one end of which is connected to a first water outlet conduit 45, which is connected to the bottom of the filter 1, and a water outlet switch valve 451 is connected to the first water outlet conduit 45. The other end of the water outlet observation tank 44 is connected to a second water outlet conduit 46, which is connected to a collection tank.

[0045] In some embodiments, a first high-precision water pressure sensor 421 is connected inside the first water inlet pipe 42, and the first high-precision water pressure sensor 421 is used to detect the water pressure inside the first water inlet pipe 42; a second high-precision water pressure sensor 452 is connected inside the first water outlet pipe 45, and the second high-precision water pressure sensor 452 is used to detect the water pressure inside the first water outlet pipe 45.

[0046] In some embodiments, a light irradiation unit 47 is connected to one side of the water outlet observation tank 44, the light irradiation unit 47 being used to emit a light source towards the water outlet observation tank 44 from the side; a side observation unit 48 is connected to the other side of the water outlet observation tank 44, the side observation unit 48 being used by the user to observe the light irradiation unit 47; and an upper observation unit 49 is connected to the upper side of the water outlet observation tank 44, the upper observation unit 49 being used by the user to observe the water outlet observation tank 44 from above.

[0047] In this embodiment, the first high-precision water pressure sensor 421 can detect the water pressure in the first inlet pipe 42 in real time. Operators can adjust the parameters of the inlet water pump based on the feedback data to ensure that the water pressure entering the filter 1 remains stable within a suitable range, avoiding negative impacts on the cleaning effect and the filter's lifespan due to excessively high or low water pressure. The second high-precision water pressure sensor 452 can detect the water pressure in the first outlet pipe 45. By comparing and analyzing the inlet and outlet water pressures, the cleaning status of impurities in the filter 1 can be detected in a timely manner.

[0048] The design of the water outlet observation tank 44, along with the lighting unit 47, side observation unit 48, and top observation unit 49, enables multi-angle and all-round observation of the cleaning fluid. The lighting unit 47 emits a light source from the side towards the water outlet observation tank 44, providing good illumination conditions for observation and making impurities in the cleaning fluid more clearly visible. The side observation unit 48 and the top observation unit 49 provide users with different observation perspectives from the side and above, respectively. Operators can choose the appropriate observation method as needed (such as observing light transmittance or light spot when observing from the side) to more accurately judge the cleaning effect of the filter 1 and the residual amount of internal impurities, thereby adjusting the cleaning process in a timely manner and improving the cleaning quality.

[0049] In some embodiments, the filter 1 is connected to a feed pipe 11, the feed pipe 11 is connected to a feed valve 12, the lower end of the filter 1 is connected to a discharge pipe 13, and the discharge pipe 13 is connected to a discharge valve 14.

[0050] In this embodiment, the feed pipe 11 is installed on the upper side of the filter 1, and the discharge pipe 13 is installed at the bottom of the filter 1.

[0051] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: By combining air cleaning, steam cleaning, and water washing components, comprehensive and deep cleaning of the filter media within the filter is achieved. The air cleaning component utilizes the flow of gas through the tiny gaps between filter media particles to thoroughly flush the media, efficiently and quickly removing most impurities from the surface, laying the foundation for subsequent deep cleaning. The steam cleaning component targets stubborn impurities within the filter, effectively softening and dissolving difficult-to-remove dirt through the high temperature and pressure of steam, further enhancing the thoroughness of the cleaning. The water washing component leverages the powerful impact and adsorption capacity of water to completely remove residual impurities, ensuring the filter media regains its optimal filtration performance, significantly improving filtration efficiency and quality. This solution addresses the problems of existing technologies, such as long backwashing times, excessive wastewater generation, incomplete backwashing, filter clogging over time, upper packing material agglomeration, decreased processing load, increased effluent quality, increased filter media wear, and easy damage to filter internal components.
