Description

Technical Field

[0001] This utility model relates to the technology in the field of wastewater treatment, and in particular to a spray stripping device used in wastewater with high free ammonia content. Background Technology

[0002] In modern industrial production, such as the fertilizer, slaughtering, food, and medical industries, large amounts of wastewater rich in ammonia nitrogen are generated. If this wastewater is discharged directly without proper treatment, it will have a serious impact on the environment. Excessive ammonia nitrogen can lead to eutrophication of water bodies, causing excessive algae growth and disrupting the aquatic ecological balance. At the same time, ammonia nitrogen may also be converted into ammonia gas in the atmosphere, exacerbating acid rain. In addition, long-term exposure to high ammonia nitrogen wastewater may lead to soil acidification, reduced crop yields, and even threaten human health.

[0003] Currently, ammonia nitrogen wastewater is mainly treated using traditional biological processes, with nitrification as the core reaction. However, general biological systems cannot effectively handle high-concentration ammonia nitrogen wastewater. Excessive ammonia nitrogen concentration can even lead to nitrifying bacteria poisoning, resulting in the paralysis of the biological system. Existing ammonia nitrogen stripping devices typically connect multiple treatment units in series, allowing the wastewater to pass through each unit sequentially to achieve sedimentation, stripping, and adsorption treatments. However, their structural design is suboptimal, each treatment step takes a long time, and each piece of equipment requires installation space, increasing the overall size of the treatment unit and failing to meet user needs, thus limiting its applicability.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a spray stripping device for use in high-free ammonia wastewater. Through the integrated design of each component, it achieves the treatment of wastewater at each stage, eliminating the need for separate installation and use of each treatment device. At the same time, the wastewater moves towards the adsorption chamber during the stripping process, making full use of the blower's airflow, which helps to reduce the total air volume and the system's energy consumption. Furthermore, the three-layer activated carbon adsorption layer improves the filtration effect of the wastewater, meets the user's needs, and has a wide range of applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A spray stripping device for high-free-ammonia wastewater includes a shell and a blower and an adsorption device mounted on the shell. The shell contains a water storage tank, an outlet tank, a stripping chamber, and an adsorption chamber. The water storage tank and outlet tank are arranged at intervals. An inlet and an outlet are provided on the outside of the shell corresponding to the water storage tank and outlet tank. The stripping chamber is located between the water storage tank and outlet tank, and the water storage tank and stripping chamber are connected by several guide holes. The blower is located on one side of the stripping chamber, and the adsorption chamber is located on the other side of the stripping chamber away from the blower and is connected to both the stripping chamber and outlet tank. The adsorption chamber has several exhaust ports connected to the outside. The adsorption device is located inside the adsorption chamber and includes an activated carbon adsorption layer. At least three layers of activated carbon adsorption are arranged at intervals between the stripping chamber and the exhaust ports. Wastewater from the water storage tank flows into the stripping chamber through the guide holes for stripping treatment, then enters the adsorption chamber for multiple adsorption treatments before flowing into the outlet tank.

[0007] As a preferred embodiment, a protective net is provided on the side of the adsorption chamber away from the stripping chamber, the protective net being located inside the exhaust port, and the mesh size of the protective net being smaller than that of the exhaust port.

[0008] As a preferred embodiment, the water storage tank is provided with a guide surface extending obliquely downwards towards the guide holes, the guide surface is located below the water inlet, and a number of guide holes are located on the side of the lowest side of the guide surface.

[0009] As a preferred embodiment, the water storage tank is equipped with a filter screen inside, which is located above a plurality of flow guide holes and beside the flow guide surface.

[0010] As a preferred embodiment, the water storage tank is provided with an installation step, which extends in a ring shape, and a number of guide holes are located in the inner perimeter of the installation step. The filter screen is detachably installed at the upper end of the installation step.

[0011] As a preferred embodiment, the filter screen is provided with at least two screens arranged vertically at intervals, the aperture of the filter screen located on the lower side is smaller than the aperture of the filter screen located on the upper side, and a distance is maintained between the filter screen located on the lower side and several guide holes.

[0013] As a preferred embodiment, the inner wall surfaces of the water storage tank, the air stripping chamber, and the adsorption chamber are all provided with a waterproof and corrosion-resistant layer.

[0014] As a preferred embodiment, the waterproof and corrosion-resistant layer is one of a chlorinated polyethylene coating or a polyamide resin coating.

[0015] As a preferred embodiment, a liquid level probe is installed inside the water storage tank.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly achieves wastewater treatment through the integrated design of various components. After the wastewater is treated by sedimentation in the water storage tank, it flows into the stripping chamber through several guide holes for stripping treatment, then enters the adsorption chamber for adsorption treatment, and finally flows into the effluent tank. This realizes the treatment of wastewater in each process, eliminating the need for separate installation and use of each treatment device. At the same time, the wastewater moves towards the adsorption chamber during the stripping treatment process, making full use of the blower's airflow, which helps to reduce the total air volume and the system's energy consumption. Furthermore, the setting of three activated carbon adsorption layers improves the filtration effect of wastewater. The ingenious and reasonable structural design reduces the treatment time of wastewater in each process, reduces the space occupied by the equipment, meets the user's needs, and has a wide range of applications. Secondly, the protective net is designed to further filter the emitted gas, thereby reducing impurities in the gas and meeting emission standards. It has excellent usability. At the same time, the guide surface is designed to guide the flow of wastewater on the storage tank. Furthermore, the filter screen is designed to allow impurities after wastewater sedimentation to accumulate on the filter screen, preventing impurities from clogging the guide holes. In particular, the design of two filter screens with different mesh sizes further prevents impurities from clogging the guide holes, ensuring smooth flow of wastewater and strong practicality. Furthermore, the installation steps facilitate the installation and positioning of the filter screen on the water storage tank. The handle facilitates the removal and use of the filter screen, allowing users to easily remove impurities from the filter screen for subsequent water storage tank treatment. Additionally, the waterproof and corrosion-resistant layer improves the waterproof and corrosion-resistant performance of the water storage tank, air-blowing chamber, and adsorption chamber, thereby extending their service life and ensuring excellent usability.

The water storage tank 13 and the water outlet tank 14 are arranged at intervals. The housing 10 is provided with an inlet 101 and an outlet 102 corresponding to the water storage tank 13 and the water outlet tank 14. The stripping chamber 15 is located between the water storage tank 13 and the water outlet tank 14. The water storage tank 13 and the stripping chamber 15 are connected by a plurality of guide holes 131. The blower 11 is mounted on one side of the stripping chamber 15 via a mounting bracket 111. The adsorption chamber 16 is located on the other side of the stripping chamber 15 away from the blower 11 and is connected to the stripping chamber 15 and the water tank 14 respectively. The adsorption chamber 16 is provided with several exhaust ports 103 that communicate with the outside. The adsorption device 12 is located inside the adsorption chamber 16. The adsorption device 12 includes an activated carbon adsorption layer 121. The activated carbon adsorption layer 121 is provided with at least three layers and is arranged at intervals between the stripping chamber 15 and the exhaust ports 103. In operation, wastewater from the storage tank flows into the stripping chamber through the guide holes for stripping treatment, then enters the adsorption chamber for multiple adsorption treatments before flowing into the effluent tank. Thus, through the integrated design of each component, wastewater undergoes sedimentation treatment in the storage tank, flows through several guide holes into the stripping chamber for stripping treatment, then enters the adsorption chamber for adsorption treatment before flowing into the effluent tank. This achieves multi-stage wastewater treatment, eliminating the need for separate installation and use of each treatment device. Simultaneously, the wastewater moves towards the adsorption chamber during the stripping process, fully utilizing the blower's airflow, which helps reduce the total air volume and system energy consumption. Furthermore, the three-layer activated carbon adsorption layer improves the wastewater filtration effect. The ingenious and reasonable structural design reduces the wastewater treatment time in each stage, minimizes equipment space occupation, meets user needs, and has a wide range of applications.

[0022] Furthermore, a protective net 17 is provided on the side of the adsorption chamber 16 away from the stripping chamber 15. The protective net 17 is located inside the exhaust port 103, and the mesh size of the protective net 17 is smaller than that of the exhaust port 103. In this way, the protective net is set to filter the exhaust gas again, thereby reducing impurities in the gas and meeting the emission standards, resulting in good usability.

[0023] Furthermore, the water storage tank 13 is provided with a guide surface 132 extending obliquely downwards towards the guide holes. The guide surface 132 is located below the water inlet 101. Several guide holes 131 are located beside the lowest side of the guide surface 132. A filter screen 133 is provided inside the water storage tank 13. The filter screen 133 is located above the several guide holes 131 and beside the guide surface 132. Specifically, the water storage tank 13 is provided with an installation step 134. The installation step 134 is annularly extended. Several guide holes 131 are located within the inner perimeter of the installation step 134. The edge of the filter screen 133 is detachably mounted on the installation step 134. Preferably, at the upper end of the step 134, at least two filter screens 133 are arranged vertically at intervals. The aperture of the filter screen 133 on the lower side is smaller than that on the upper side. A distance is maintained between the filter screen 133 on the lower side and several guide holes 131. In this way, the guide surface is set to guide the flow of wastewater on the water storage tank. Moreover, the filter screen is set so that impurities after wastewater sedimentation accumulate on the filter screen, avoiding impurities from clogging the guide holes. In particular, the setting of two filter screens with different apertures further avoids impurities from clogging the guide holes, ensuring smooth flow of wastewater and strong practicality.

[0024] Furthermore, the mounting step 134 has an upwardly extending positioning part 135, and the edge of the filter screen 133 is provided with a positioning port 136 for matching the positioning part. The positioning part 135 and the positioning port 136 are mutually adapted and positioned to realize the assembly and positioning of the filter screen 133 on the mounting step 134. Preferably, the upper end of the filter screen 133 is provided with a handle 137 for the user to disassemble and put away. The lower end of the filter screen 133 on the upper side contacts and positions with the upper end of the handle 137 on the lower side of the filter screen 133. Thus, the positioning part and the positioning port are provided to facilitate the assembly and positioning of the filter screen. Combined with the handle, it is beneficial to take away and put away the filter screen, which is convenient for the user to remove the impurities on the filter screen for subsequent water storage tank treatment. It is also convenient for positioning between the two filter screens.

[0025] Furthermore, the inner wall surfaces of the water storage tank 13, the air stripping chamber 15, the adsorption chamber 16, and the guide hole 131 are all provided with a waterproof and corrosion-resistant layer 18. Preferably, the waterproof and corrosion-resistant layer 18 is one of a chlorinated polyethylene coating or a polyamide resin coating. Alternatively, the waterproof and corrosion-resistant layer 18 is provided in two layers, namely a chlorinated polyethylene coating and a polyamide resin coating, respectively, and is arranged sequentially inside and outside. In this way, the waterproof and corrosion-resistant layer improves the waterproof and corrosion-resistant performance of the water storage tank, the air stripping chamber, and the adsorption chamber, thereby increasing the service life of the water storage tank, the air stripping chamber, and the adsorption chamber, and improving their usability.

[0026] Furthermore, a level probe 19 is provided inside the water storage tank 13. The level probe 19 is located on the side of the water storage tank 13 away from the water inlet 101. Preferably, an electric valve (not shown in the figure) is provided at the water inlet 101. A control device 20 is provided outside the housing 10. The control device 20 is connected to the level probe 19, the electric valve, and the blower 11. When the wastewater reaches the level probe position and is about to overflow, the level probe feeds back the monitored signal to the control device, and the control device controls the opening or closing of the electric valve.

[0027] The key design feature of this utility model lies in its integrated design of various components. Wastewater undergoes sedimentation treatment in a storage tank, then flows through several guide holes into a stripping chamber for stripping, followed by adsorption treatment in an adsorption chamber before flowing into an effluent tank. This achieves multi-stage wastewater treatment, eliminating the need for separate installation and use of each treatment device. Furthermore, the wastewater moves towards the adsorption chamber during the stripping process, maximizing the use of the blower's airflow, thus reducing the total air volume and system energy consumption. The three-layer activated carbon adsorption system further enhances the wastewater filtration effect. The ingenious and rational structural design reduces the wastewater treatment time in each stage, minimizes equipment space requirements, meets user needs, and has a wide range of applications. Secondly, the protective net is designed to further filter the emitted gas, thereby reducing impurities in the gas and meeting emission standards. It has excellent usability. At the same time, the guide surface is designed to guide the flow of wastewater on the storage tank. Furthermore, the filter screen is designed to allow impurities after wastewater sedimentation to accumulate on the filter screen, preventing impurities from clogging the guide holes. In particular, the design of two filter screens with different mesh sizes further prevents impurities from clogging the guide holes, ensuring smooth flow of wastewater and strong practicality. Furthermore, the installation steps facilitate the installation and positioning of the filter screen on the water storage tank. The handle facilitates the removal and use of the filter screen, allowing users to easily remove impurities from the filter screen for subsequent water storage tank treatment. Additionally, the waterproof and corrosion-resistant layer improves the waterproof and corrosion-resistant performance of the water storage tank, air-blowing chamber, and adsorption chamber, thereby extending their service life and ensuring excellent usability.
