Abstract
Description
Technical Field
[0001] This utility model relates to the field of ammonia nitrogen removal technology, and in particular to an ammonia nitrogen removal device for ion exchange resin production wastewater. Background Technology
[0002] In industrial production, especially during the production of ion exchange resins, wastewater often contains high concentrations of ammonia nitrogen. Ammonia nitrogen, a common pollutant, not only severely pollutes water bodies but also has adverse effects on the ecological environment and human health. If this wastewater is discharged directly without effective treatment, it can lead to eutrophication, causing abnormal proliferation of aquatic plants and algae, and disrupting the aquatic ecosystem. Simultaneously, ammonia nitrogen is toxic to aquatic organisms and poses a potential threat to human health through the food chain.
[0003] Existing ammonia nitrogen removal technologies mainly include biological methods, physicochemical methods, and chemical adsorption methods. However, these technologies have certain limitations in practical applications. For example, biological methods have high requirements for water quality, long treatment times, and are sensitive to external conditions (such as temperature and pH), leading to unstable treatment results. Physicochemical methods, while having high treatment efficiency, typically require complex equipment and high energy consumption, resulting in high operating costs. Chemical adsorption methods, although effective in removing ammonia nitrogen, have high-cost adsorption materials with limited lifespans, and frequent replacement of these materials increases operating costs and workload.
[0004] Against this backdrop, existing technologies for ammonia nitrogen removal still suffer from problems such as low treatment efficiency, high operating costs, complex equipment, and sensitivity to environmental conditions, failing to meet the demands for efficient, economical, and environmentally friendly treatment of industrial wastewater. Therefore, there is an urgent need for an ammonia nitrogen removal device that is simple in structure, easy to operate, highly efficient, and environmentally friendly, to overcome the shortcomings of existing technologies and to achieve stable and continuous ammonia nitrogen removal. Utility Model Content
[0005] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0007] Preferably, the tank body, partition frame, and top cover are fixedly connected by quick-release bolts, and sealing gaskets are provided at the joints between the tank body, partition frame, and top cover. Here, the quick-release bolt connection makes the disassembly and assembly of the tank body, partition frame, and top cover more convenient, facilitating the cleaning, maintenance, and repair of the equipment, while the sealing gaskets ensure the sealing performance of the equipment during operation, preventing leakage and improving the safety and efficiency of the equipment.
[0008] Preferably, a splash guard is fixedly installed inside the tank, located above the water inlet. Here, the splash guard effectively prevents water from splashing during water intake, thus avoiding direct impact of water on the tank's interior, protecting the equipment's structure and internal components, reducing equipment wear caused by water splashes, and also reducing the volatilization of ammonia nitrogen.
[0009] Preferably, the surface of the splash guard is provided with a gauze layer. Here, the gauze layer further improves the splash-proof effect, increases the dispersion and buffering of water flow, effectively reduces liquid splashing, improves the uniform distribution of wastewater inside the tank, and optimizes the wastewater treatment effect.
[0010] Preferably, a motor is fixedly installed on the bottom surface of the tank, a rotating rod is fixedly installed on the output end of the motor, and a stirring blade is fixedly installed on the surface of the rotating rod. Here, the motor drives the stirring blade to rotate, which can continuously stir the wastewater in the tank, so that the wastewater and the absorbent are fully mixed, improving the ammonia nitrogen removal efficiency. At the same time, stirring helps to maintain the homogeneity of the water, avoid sedimentation, and ensure that the treatment effect of the entire system is more stable and efficient.
[0011] Preferably, the ammonia nitrogen removal device for ion exchange resin production wastewater further includes an absorption tank, the inside of which is filled with acid, and the gas pipe is connected to the acid inside the absorption tank. Here, the gas pipe introduces ammonia gas into the acid inside the absorption tank, where the acid can effectively neutralize or absorb the ammonia gas, reducing ammonia emissions. This not only avoids ammonia pollution to the environment but also improves the ammonia nitrogen removal rate.
[0012] Preferably, an exhaust port is fixedly installed on the top surface of the absorption box. This exhaust port ensures that no gas pressure buildup occurs during the process, guaranteeing the smooth progress of the absorption process and preventing excessive gas pressure from damaging the equipment.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, by setting a stirring device and a heating layer inside the tank, the device can effectively stir the wastewater and absorbent during the wastewater treatment process, so that the ammonia nitrogen in the wastewater reacts fully with the absorbent, and the heating promotes the volatilization of ammonia nitrogen, further improving the efficiency of ammonia nitrogen removal, ensuring the uniformity of wastewater in the treatment process, avoiding the reduction in efficiency caused by sedimentation or uneven local treatment, and ensuring the overall stability of the equipment.
[0015] 2. In this utility model, by introducing the ammonia gas volatilized in the tank into the absorption box outside the device, and using the acid liquid inside the box to neutralize the ammonia gas, the environmental pollution caused by the direct discharge of ammonia gas into the air is greatly reduced. The presence of the acid liquid ensures that the ammonia gas is fully absorbed and converted, making the treatment process more environmentally friendly and in line with the environmental protection standards for waste gas emissions. The exhaust port not only maintains the pressure balance inside and outside the equipment and ensures the smooth progress of the absorption process, but also further improves the overall safety of the system and prevents the equipment from malfunctioning due to excessive pressure.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] Example 1:
[0025] Please see Figure 1-4 This utility model provides a technical solution: an ammonia nitrogen removal device for ion exchange resin production wastewater, including a support base 1, a tank 2 fixedly mounted on the surface of the support base 1, a partition frame 12 fixedly mounted on the top of the tank 2, and a top cover 14 fixedly mounted on the top of the partition frame 12. The tank 2, partition frame 12, and top cover 14 are fixedly connected by quick-release bolts, and sealing gaskets are provided at the connections between the tank 2, partition frame 12, and top cover 14. The quick-release bolt connection makes the disassembly and assembly of the tank 2, partition frame 12, and top cover 14 more convenient, facilitating the cleaning, maintenance, and repair of the equipment. The sealing gaskets ensure the sealing of the equipment during operation, preventing equipment leakage and improving the safety and efficiency of the equipment. An air pipe 15 is fixedly mounted on the top of the top cover 14. An inlet 3 and an outlet 4 are fixedly mounted on the surface of the tank 2. A heating layer 5 is fixedly mounted on the bottom of the tank 2, and a heating wire 6 is fixedly mounted inside the heating layer 5. A blower 13 is fixedly mounted inside the partition frame 12. A splash guard 10 is fixedly installed inside the tank 2, located above the water inlet 3. The splash guard 10 effectively prevents water from splashing during water intake, thus avoiding direct impact of water on the inside of the tank 2, protecting the equipment structure and internal components, reducing equipment wear caused by water splashes, and also reducing the volatilization of ammonia nitrogen. A gauze layer 11 is provided on the surface of the splash guard 10, which further improves the splash prevention effect, increases the dispersion and buffering of water flow, effectively reduces liquid splashing, improves the uniform distribution of wastewater inside the tank 2, and optimizes the wastewater treatment effect. A motor 7 is fixedly installed on the bottom surface of the tank 2, and a rotating rod 8 is fixedly installed on the output end of the motor 7. An agitator 9 is fixedly installed on the surface of the rotating rod 8. The motor 7 drives the agitator 9 to rotate, which can continuously agitate the wastewater in the tank 2, so that the wastewater and absorbent are fully mixed, improving the ammonia nitrogen removal efficiency. At the same time, agitation helps to maintain the uniformity of the water, avoid sedimentation, and ensure that the treatment effect of the entire system is more stable and efficient.
[0026] Example 2:
[0027] Please see Figure 1-2The ammonia nitrogen removal device for ion exchange resin production wastewater also includes an absorption tank 16. An acid solution 18 is installed inside the absorption tank 16. A gas pipe 15 is connected to the acid solution 18 inside the absorption tank 16. The gas pipe 15 introduces ammonia gas into the acid solution 18 inside the absorption tank 16. The acid solution 18 can effectively neutralize or absorb ammonia gas, reducing ammonia gas emissions. This not only avoids ammonia gas pollution to the environment but also improves the ammonia nitrogen removal rate. An exhaust port 17 is fixedly installed on the top surface of the absorption tank 16. The exhaust port 17 ensures that there is no gas pressure buildup during the treatment process, ensuring the smooth progress of the absorption process and preventing excessive gas pressure from damaging the equipment.
[0028] Working Principle: Ammonia-containing wastewater generated during the ion exchange resin production process enters the tank 2 of the device through inlet 3. To avoid splashing and impact caused by excessive water flow during inlet, a splash guard 10 is specially installed inside the tank 2, located directly above the inlet 3. Furthermore, the surface of the splash guard 10 is covered with a layer of gauze 11. The gauze layer 11 further reduces the water flow velocity and increases the water flow dispersion effect, effectively preventing water splashing and reducing the risk of liquid directly impacting the internal structure of the tank 2. In addition, the combination of the splash guard 10 and the gauze also reduces the amount of ammonia nitrogen volatilized when it first enters the device, which helps to improve the stability and efficiency of the overall wastewater treatment. After the wastewater enters the tank 2 and undergoes the initial splash guard treatment, the wastewater located in the tank... The motor 7 at the bottom of tank 2 starts, driving the connected rotating rod 8 and the stirring blades 9 mounted on the surface to perform stirring. The continuous operation of the stirring blades 9 ensures the uniform flow of wastewater in tank 2, allowing the wastewater to be fully mixed with the added absorbent. Stirring allows the ammonia nitrogen in the wastewater to react more fully with the absorbent, further improving the reaction efficiency. At the same time, stirring helps to avoid the precipitation of solid impurities and ensures the uniform flow of wastewater in tank 2, ensuring the uniformity of wastewater treatment and laying the foundation for the subsequent ammonia nitrogen volatilization and removal. During the stirring process, the heating layer 5 at the bottom of tank 2 begins to heat the wastewater. Heating wires 6 are installed inside the heating layer 5 to provide continuous heat to tank 2, gradually heating the wastewater to a temperature suitable for ammonia nitrogen volatilization.Heating converts ammonia nitrogen in wastewater into ammonia gas. The increased temperature accelerates ammonia production and facilitates its rapid separation from the wastewater. Working in conjunction with a stirring system, the ammonia nitrogen in the wastewater is effectively released under the combined effects of high temperature and stirring, ensuring full volatilization and reducing the ammonia nitrogen content in the wastewater. After the ammonia nitrogen in the wastewater is converted into ammonia gas under heating, the top-mounted blower 13 starts operating. The airflow generated by the blower 13 transports the ammonia gas in tank 2 through the top-connected gas pipe 15 to the external absorption box 16. The ammonia gas volatilized inside tank 2 is not directly discharged into the atmosphere but enters the absorption box 16 for further treatment, effectively controlling the ammonia gas emission path and preventing untreated ammonia gas from entering the atmosphere and causing air pollution. The absorption box 16 is pre-filled with a certain amount of acid solution 18. When the ammonia gas enters the absorption tank 16, it undergoes a neutralization reaction with the acid solution 18. The ammonia molecules in the ammonia gas combine with the acid molecules in the acid solution 18 to form a stable compound, thus converting the originally gaseous ammonia gas into a liquid or solid compound. This successfully completes the absorption and neutralization of ammonia gas. This process not only significantly reduces the direct emission of ammonia gas but also improves the overall ammonia nitrogen removal effect. During the absorption of ammonia gas, the top surface of the absorption tank 16 is also equipped with an exhaust port 17. The presence of the exhaust port 17 can prevent excessive gas pressure from being generated in the absorption tank 16, ensuring that the entire equipment is always in a stable gas pressure balance state during operation. After the ammonia gas in the absorption tank 16 reacts with the acid solution 18, the remaining gas is discharged through the exhaust port 17. The exhaust port 17 not only avoids equipment damage caused by pressure accumulation but also ensures the smooth progress of the entire absorption process.
