Description

Technical Field

[0001] The invention belongs to the field of garbage and sewage treatment, and particularly relates to an odor treatment device for a garbage treatment sewage pool. Background Art

[0002] Garbage is solid waste generated in human daily life and production. Due to its large discharge volume, complex and diverse composition, and its pollution, resource and social nature, it needs to be harmless, resource-based, reduced and socialized. If it is not properly handled, it will pollute the environment, affect environmental hygiene, waste resources, damage production and living safety, and destroy social harmony. Garbage disposal is to quickly remove the garbage, treat it harmlessly, and finally make reasonable use of it. The widely used garbage disposal methods today are sanitary landfill, high-temperature composting and incineration. The purpose of garbage disposal is harmlessness, resource utilization and reduction.

[0003] In the process of garbage treatment, garbage leachate is generally produced. The general treatment method is to transfer the leachate from the collection tank to the drum screen filter through a lifting pump to remove large suspended particles and floating objects, overflow to the pre-sedimentation tank, remove the substances with higher specific gravity in the leachate through gravity sedimentation, and then overflow to the regulating tank (or accident tank); enter the top of the UASB reactor through the regulating tank lifting pump, and the leachate undergoes anaerobically fermented in the UASB reactor to open the chain links or benzene rings of the high molecular substances, making them small molecules that are more easily biodegradable (remove COD in sewage), and produce biogas (the produced biogas is burned with a torch for treatment), and overflow from the top of the UASB reactor into the anaerobic effluent sedimentation tank at night. The supernatant after sedimentation The liquid enters the denitrification tank and nitrification tank in the MBR treatment process, and through nitrification and denitrification, organic matter and ammonia nitrogen are further removed (the main removal matter in the MBR treatment process is ammonia nitrogen). The treated sewage enters the ultrafiltration system through the ultrafiltration water inlet pump for mud and water separation, and the concentrated liquid is returned to the denitrification tank. The clear liquid enters the nanofiltration system to remove most of the divalent and multivalent ions and organic matter with a molecular weight of 200-1000, and a small amount of monovalent ions. The effluent enters the RO system for further treatment, which can remove impurities such as inorganic ions, bacteria, viruses, organic matter and colloids in the water, so that the effluent meets the reuse standard requirements. Qualified water is sent to the clear liquid tank for reuse, and the nanofiltration and reverse osmosis concentrates enter the concentrate tank and then reused.

The illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0025] like Figures 1 to 6 As shown, in one embodiment, an odor treatment device for a garbage treatment sewage pool of the present invention comprises a sealing cover 2 installed above a sewage pool 1, a suction component 3 is installed on the top of the sealing cover 2, the suction component 3 is used to collect and discharge the odor generated in the sewage pool 1, and the output end of the suction component 3 is connected to a pretreatment component 4 through a first exhaust pipe 31, which is used to send the collected odor into the pretreatment component 4 for treatment, so as to pre-treat the collected odor, the output end of the pretreatment component 4 is connected to a purification box 5 through a second exhaust pipe 32, a purification component 6 is installed inside the purification box 5, the purification component 6 is used to purify the odor treated by the pretreatment component 4, and a cleaning device 7 is also installed inside the purification box 5, the cleaning device 7 is used to clean the surface of the purification component 6, and an air supply pipe 9 is installed on the top of the purification box 5; Among them, the pretreatment component 4 includes a caustic washing tower 41 which is connected to the first exhaust pipe 31, and the first packing layer 42 and the second packing layer 43 are respectively arranged at the bottom and the top of the caustic washing tower 41, a first sprayer 44 is arranged on the top of the first packing layer 42, and a second sprayer 45 is arranged on the top of the second packing layer 43, the first sprayer 44 and the second sprayer 45 are both connected to the infusion pipe 46, and the end of the infusion pipe 46 is connected to the washing tank 47 located at the bottom of the caustic washing tower 41, the top of the caustic washing tower 41 is connected to the purification box 5 through the second exhaust pipe 32, and the purification component 6 includes an ion generator 61 arranged in the middle position of the purification box 5, and the top and the bottom of the ion generator 61 are respectively installed with a gas collector 62 and a disperser 63, and the middle position of the gas collector 62 and the disperser 63 is provided with a power generation component 8, and the power generation component 8 is electrically connected to the cleaning device 7 so as to generate electricity through the power generation component 8 to power the cleaning device 7.

[0026] In this embodiment, the sewage generated during the garbage disposal process is accumulated in the sewage pool 1. A sealing cover 2 is provided above the sewage pool 1 to effectively prevent the odor inside the sewage pool 1 from diffusing to the outside, thereby playing a sealing role. Afterwards, the odor generated in the sewage pool 1 is continuously extracted outward by the exhaust assembly 3 so as to be transported to the pretreatment assembly 4 for pretreatment. Specifically, the odor enters the alkali washing tower 41 through the first exhaust pipe 31, and passes through the first packing layer 42, the first sprayer 44, the second packing layer 43 and the second sprayer 45 in sequence. The first packing layer 42 and the second packing layer 43 use PE as a filler to increase the contact surface with the odor, that is, to facilitate the subsequent first sprayer 44 and the second sprayer 45 to spray alkali solution for cleaning, so as to effectively remove particulate matter, hydrogen sulfide, ammonia, easily oxidized organic odorous gases and grease substances in the waste gas, and reduce the load on the subsequent biological treatment equipment. After the pretreatment, the gas enters the purification box 5 through the second exhaust pipe 32 at the top of the alkali washing tower 41 for secondary purification. Negative ions are generated by the ion generator 61 in the purification component 6 inside the purification box 5, and the contact area between the gas and the plasma generator 61 is increased by using the gas collector 62 and the disperser 63 installed inside the purification box 5, thereby improving the purification effect of the gas. In addition, during the purification process, the airflow is further concentrated by the gas collector 62 and the disperser 63, so that the power generation component 8 can realize wind power generation, and the power generation component 8 is used to power the cleaning device 7, so that the cleaning device 7 can clean the purification component 6 inside the purification box 5 at any time, thereby ensuring that the purification component 6 can maintain a good purification effect even after long-term use, and improving the purification efficiency of odor.

[0027] It should be noted that the first sprayer 44 and the second sprayer 45 are both provided with nozzles 49 at their bottom ends, and the spraying ranges of the nozzles 49 at adjacent positions partially overlap.

[0028] After the extracted gas enters the alkali washing tower 41, it passes through the first packing layer 42, the first sprayer 44, the second packing layer 43 and the second sprayer 45 at the bottom in sequence, and the particulate matter and chemical substances in the odor are absorbed by the packing in the first packing layer 42 and the second packing layer 43. After absorption, the alkaline liquid is sprayed by the first sprayer 44 and the second sprayer 45 and drips on the first packing layer 42 and the second packing layer 43 respectively. On the one hand, the alkaline liquid is in direct contact with the air above the first packing layer 42 and the air above the second packing layer 43 for neutralization. On the other hand, the sprinkled alkaline liquid is in direct contact with the surface of the first packing layer 42 and the second packing layer 43, and reacts with the substances adsorbed on the surface of the first packing layer 42 and the second packing layer 43 to achieve the neutralization of the pickling substances in the odor. Since the odor generated by the sewage pool generally contains various impurities, it is easy to form blockage on the surface of the nozzle 49 of the first sprayer 44 and the second sprayer 45 after long-term use. In order to further improve the neutralization effect of the first sprayer 44 and the second sprayer 45, the nozzles 49 at adjacent positions of the first sprayer 44 and the second sprayer 45 are set to partially overlap the spraying range, thereby effectively reducing the impact of the blockage of the nozzle 49, ensuring that the alkaline liquid sprayed from the nozzle 49 can cover various positions, thereby improving the alkaline washing treatment effect on the odor inside the alkaline washing tower 41.

[0029] In some embodiments, the sealing cover 2 includes a steel bracket 21 installed on the top of the sewage pool 1, and a layer of fluorocarbon fiber membrane 22 is laid on the outside of the steel bracket 21. The fluorocarbon fiber membrane 22 has good corrosion resistance and ensures that the sealing effect will not be affected after long-term use.

[0030] In some other embodiments, the ion generator 61 includes an ion box 611 arranged inside the purification box 5, and a plurality of first ion reaction rods 612 and a plurality of second ion reaction rods 613 are evenly arranged on both sides of the inner wall of the ion box 611, the outer walls of the first ion reaction rods 612 and the second ion reaction rods 613 are both sleeved with a sleeve 616 with holes, and the adjacent first ion reaction rods 612 and the second ion reaction rods 613 are staggered, and the first ion reaction rods 612 and the second ion reaction rods 613 are connected at the connection between the first ion reaction rod 612 and the ion box 611. The connection between the second ion reaction rod 613 and the ion box 611 is connected to a second guide plate 615, and the first guide plate 614 and the second guide plate 615 are both arranged to be inclined.

[0031] After the pretreatment process of the odor is completed inside the alkali washing tower 41, the pretreated odor is extracted through the second exhaust pipe 32 and discharged into the purification box 5, and is secondary purified by the purification component 6 inside the purification box 5, that is, the ion generator 61 disposed inside the purification box 5 continuously generates negative ions to purify the odor. Specifically, after the pretreated odor enters the purification box 5, it first passes through the gas collector 62 and enters the ion box 611, and then passes through the first ion reaction rods 612 and the second ion reaction rods 613 on both sides in sequence, and the generated negative ion gas is ejected into the ion box 611 through the sleeve 616 with spaces on the outside. The generated negative ions directly contact and react with the odor inside the ion box 611. Due to the strong activity of negative ions, most of the odor molecules are bombarded by plasma, and the chemical bonds with odorous gases are broken, reducing the odor concentration of the odorous gas, and playing a good purification role.

[0032] In some other embodiments, the gas collector 62 includes a first contraction bucket 621 installed at the bottom end of the ion box 611, and the narrower end of the first contraction bucket 621 is connected to the first expansion bucket 622. The disperser 63 includes a second contraction bucket 631 installed at the top end of the ion box 611, and the narrower end of the second contraction bucket 631 is connected to the second expansion bucket 632. The inner walls of the first expansion bucket 622, the first contraction bucket 621, the second contraction bucket 631 and the second expansion bucket 632 are all installed with ultraviolet lamps.

[0033] In this embodiment, after the odor after pretreatment enters the purification box 5, it first passes through the first contraction bucket 621 to concentrate the airflow and then enters the first expansion bucket 622, so that the odor is fully in contact with the ultraviolet lamps inside the first contraction bucket 621 and the first expansion bucket 622. The odor is also destroyed by the high-intensity ultraviolet radiation field and produces active secondary oxidants. The odor molecules continue to undergo oxidative decomposition under the synergistic effect of the purification factor and the high-intensity ultraviolet light, and the odor gas is further oxidized and purified. Afterwards, the gas passing through the first expansion bucket 622 completely enters the interior of the ion box 611, and fully contacts the multiple first ion reaction rods 612 and the multiple second ion reaction rods 613 inside the ion box 611. After reacting with the negative ions, the odor is discharged through the top of the ion box 611 and enters the second contraction bucket 631 and the second expansion bucket 632 in turn. The odor is disinfected and sterilized again by the ultraviolet lamps inside the second contraction bucket 631 and the second expansion bucket 632 to oxidize and decompose the odor to ensure that the odor can be fully decomposed.

[0034] On the other hand, by setting the first contraction bucket 621 and the first expansion bucket 622, the gas entering the ion box 611 is collected and released to increase the flow rate of the gas inside the gas collector 62. At the same time, by setting the second contraction bucket 631 and the second expansion bucket 632, the gas is collected and released to increase the flow rate of the gas inside the disperser 63. On the one hand, the contact area and contact time between the odor and the ultraviolet lamp are increased, thereby improving the purification effect of the odor. On the other hand, the airflow during the treatment process can maintain a high-speed flow state inside the gas collector 62 and the disperser 63, which is convenient for the subsequent airflow power generation through the power generation component 8 to achieve effective utilization of energy.

[0035] In some further embodiments, the power generation component 8 includes two groups of driving blades 81, one group of the driving blades 81 is installed at the connection between the first expansion bucket 622 and the first contraction bucket 621, and the other group of the driving blades 81 is installed at the connection between the second expansion bucket 632 and the second contraction bucket 631. A rotating shaft 82 is connected at the center of the driving blades 81, and a generator 83 is connected to the outer end of the rotating shaft 82. The generator 83 is connected to a rechargeable battery 85 through a transformer 84, and the rechargeable battery 85 is electrically connected to the cleaning device 7.

[0036] In this embodiment, since the connection between the first expansion bucket 622 and the first contraction bucket 621, and the connection between the second expansion bucket 632 and the second expansion bucket 632 are narrow openings, the airflow converges at the connection so that the airflow velocity at the two connections is faster, which facilitates the power generation assembly 8 to generate electricity at the two connections. Specifically, since the two sets of driving blades 81 are respectively installed at the connection between the first expansion bucket 622 and the first contraction bucket 621 and the connection between the second expansion bucket 632 and the second contraction bucket 631, when the airflow passes through, the two sets of driving blades 81 are driven to rotate, thereby driving the blades 81 to drive the rotating shaft 82 at the center to rotate, and the rotation of the rotating shaft 82 drives the generator 83 to rotate, and the electricity generated by the generator 83 is stored in the rechargeable battery 85 after being transformed by the transformer, and the rechargeable battery 85 is used to power the cleaning device 7, thereby realizing energy recycling.

[0037] In some embodiments, the cleaner 7 includes a first mounting plate 71 and a second mounting plate 72 which are sleeved and mounted on the outer walls of both sides of the ion box 611. The first mounting plate 71 is mounted on the side of the ion box 611 where the first ion reaction rod 612 is mounted, and the first ion reaction rod 612 is arranged in an arc shape on the side wall of the ion box 611. The second mounting plate 72 is mounted on the side of the ion box 611 where the second ion reaction rod 613 is mounted, and the second ion reaction rod 613 is arranged in an arc shape on the side wall of the ion box 611. A drive shaft 73 is mounted at the center of the first mounting plate 71 and the second mounting plate 72. The drive shaft 73 is driven by an external drive motor, and the drive motor is powered by the power generation component 8. The outer wall of the drive shaft 73 is connected to The driving gear 74, the first mounting plate 71 and the second mounting plate 72 are rotatably connected with a plurality of first driven shafts 75 and second driven shafts 76 through bearings, each of the first driven shafts 75 is arranged between adjacent first ion reaction rods 612, and each of the second driven shafts 76 is arranged between adjacent second ion reaction rods 613. The surfaces of the first driven shaft 75 and the second driven shaft 76 are both installed with driven gears 79 meshing with the driving gear 74 on the same side, and the outer ends of the first driven shaft 75 and the second driven shaft 76 are both connected with electric push rods 77, and the surface of the electric push rods 77 is connected with a cleaning brush 78, so as to clean the sleeve 616 on the surface of the first ion reaction rods 612 and the second ion reaction rods 613 through the cleaning brush 78.

[0038] In this embodiment, since the first ion reaction rod 612 and the second ion reaction rod 613 arranged in an upper and lower arc shape are respectively arranged on both sides of the inner wall of the ion box 611, in order to avoid the sleeve 616 on the surface of the first ion reaction rod 612 and the second ion reaction rod 613 being blocked due to long-term purification of odor, affecting the generation efficiency of negative ions and thus affecting the purification effect of odor, a cleaner 7 is provided to clean the sleeve 616 on the surface of the first ion reaction rod 612 and the second ion reaction rod 613, thereby effectively removing foreign matter attached to the surface after long-term treatment of odor, ensuring that the negative ions generated by the first ion reaction rod 612 and the second ion reaction rod 613 can be quickly discharged into the interior of the ion box 611, thereby improving the purification effect of the negative ions inside the ion box 611 on odor.

[0039] Specifically, when it is necessary to clean the sleeve 616 on the surface of the first ion reaction rod 612 and the second ion reaction rod 613, the driving motor is powered by the rechargeable battery 85 of the power generation component 8. After the driving motor rotates, it drives the driving shaft 73 to rotate, and the driving gear 74 outside the driving shaft 73 also rotates accordingly. The driving gears 74 on both sides respectively drive the driven gear 79 on the first driven shaft 75 and the driven gear 79 on the second driven shaft 76 to rotate, so that each of the first driven shaft 75 and the second driven shaft 76 also rotates accordingly. Under the rotation action of the first driven shaft 75 and the second driven shaft 76, the electric push rod 77 connected to the end thereof drives the surface-mounted cleaning brush 78 to clean the sleeve 616 on the surface of the first ion reaction rod 612 and the second ion reaction rod 613 respectively, thereby effectively removing the debris on the surface of the sleeve 616, ensuring that the negative ions generated by the first ion reaction rod 612 and the second ion reaction rod 613 can be discharged normally, so as to improve the purification effect of odor.

[0040] In some further embodiments, the electric push rod 77 includes a fixed section 771 and a telescopic section 772, and the telescopic section 772 is sleeved on the outer end of the fixed section 771. The cleaning brush 78 includes a first fixed sleeve 781 installed at one end of the fixed section 771 close to the telescopic section 772 and a second fixed sleeve 782 installed at the end of the telescopic section 772. A cylindrical spring frame 783 is connected between the first fixed sleeve 781 and the second fixed sleeve 782, and a brush head 784 is connected to the outer wall of the cylindrical spring frame 783. The driving gear 74 is installed at one end of the fixed section 771 away from the telescopic section 772.

[0041] By connecting the freely retractable electric push rod 77 to the ends of the first driven shaft 75 and the second driven shaft 76, it is ensured that the electric push rod 77 can be retracted to the shortest when cleaning is not needed to reduce the obstruction to the first ion reaction rod 612 and the second ion reaction rod 613, thereby ensuring the odor purification effect of the negative ions generated by them. When cleaning is needed, after adjusting the electric push rod 77 to a suitable position, the brush head 784 outside the electric push rod 77 is driven by the first driven shaft 75 and the second driven shaft 76 to clean the sleeve 616 on the surface of the first ion reaction rod 612 and the second ion reaction rod 613.

[0042] Specifically, when cleaning is required, the electric push rod 77 is stretched outward, and the telescopic section 772 is away from the fixed section 771, so that after the second fixed sleeve 782 stretches the cylindrical spring frame 783, the brush head 784 outside the cylindrical spring frame 783 is used to clean the sleeve 616 on the surface of the first ion reaction rod 612 and the second ion reaction rod 613; when cleaning is completed or no cleaning is needed, the electric push rod 77 is retracted inward, and the telescopic section 772 is close to the fixed section 771, thereby compressing the stretched cylindrical spring frame 783, reducing the obstruction to the first ion reaction rod 612 and the second ion reaction rod 613, and ensuring the effect of the first ion reaction rod 612 and the second ion reaction rod 613 when working normally.

[0043] It should be noted that since the driving gear 74 is installed at the end of the fixed section 771 away from the telescopic section 772, and the cleaning brush 78 is installed at the end of the fixed section 771 close to the telescopic section 772 and the end of the telescopic section 772, the driving gear 74 and the cleaning brush 78 are staggered with each other, ensuring that the rotation of the driving gear 74 will not interfere with the cleaning brush 78, thereby ensuring the normal operation of the entire device.

[0044] In some further embodiments, the cylindrical spring frame 783 includes a plurality of vertical bending strips 7831, and the plurality of vertical bending strips 7831 are externally connected with a plurality of parallel annular strips 7832 to form a plurality of partition areas 7833. The brush head 784 includes a hard brush strip 7841 installed on the surface of the annular strip 7832, and the surface of the partition area 7833 is covered with a flexible pad 7842, and the surface of the flexible pad 7842 is also provided with soft bristles 7843.

[0045] In this embodiment, taking into account the random distribution of debris attached to the surface sleeve 616 of the first ion reaction rod 612 and the second ion reaction rod 613, a hard brush strip 7841 is installed on the surface of the annular strip 7832, a flexible pad 7842 is covered on the surface of the partition area 7833, and soft bristles 7843 are also provided on the surface of the flexible pad 7842. The hard brush strip 7841 and the soft bristles 7843 cooperate with each other, so that when the entire brush head 784 cleans the sleeve 616, various debris remaining on the surface of the sleeve 616 can be effectively removed, thereby improving the cleaning effect of the sleeve 616, thereby improving the odor purification efficiency of the first ion reaction rod 612 and the second ion reaction rod 613.

[0046] In some embodiments, the ion box 611 is also equipped with a collection tank 617 located at the bottom of the first ion reaction rod 612 and the bottom of the second ion reaction rod 613. The outer end of the collection tank 617 is connected to a discharge pipe 618, which facilitates the collection tank 617 to clean the debris produced by the sleeve 616 on the surface of the first ion reaction rod 612 and the second ion reaction rod 613 and discharge it outward through the discharge pipe 618.

[0047] In summary, the odor treatment device of the garbage treatment sewage pool of the present invention blocks the top of the sewage pool by setting a sealing cover to prevent the spread of odor, and at the same time, the odor generated in the sewage pool is continuously extracted outward by the exhaust component, and is sequentially subjected to alkaline washing treatment by the pretreatment component, which can effectively remove particulate matter, hydrogen sulfide, ammonia, easily oxidized organic odorous gases and oil substances in the waste gas, reduce the load on subsequent biological treatment equipment, and the gas after pretreatment enters the purification box and is subjected to ion purification by the purification component to further remove the odor in the odor, and in the process of odor treatment, the airflow when the odor flows is collected and expanded by the gas collector and the disperser to drive the power generation component to generate electricity, thereby driving the cleaning device to continuously clean the purification component inside the purification box, avoiding surface contamination of the purification component after long-term use and affecting the purification efficiency of the odor, and ensuring that the entire equipment can maintain high-efficiency purification for a long time; therefore, the present invention effectively overcomes the various shortcomings of the prior art and has a high industrial utilization value.

[0048] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
