Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste treatment, in particular to a kitchen waste ammoniation treatment system. Background Art

[0002] With the acceleration of urbanization and the improvement of living standards, the amount of food waste generated is increasing year by year. How to effectively treat this waste has become a pressing environmental issue in modern society. Traditional methods for food waste disposal, such as landfill and incineration, not only place significant pressure on the environment but also fail to effectively utilize resources. In recent years, anaerobic fermentation technology has gradually become the mainstream method for food waste treatment due to its advantages in resource utilization and waste reduction. The anaerobic fermentation process converts organic matter into biogas through the action of microorganisms, effectively reducing waste volume and enabling the production of renewable energy.

[0003] However, in the actual application of anaerobic fermentation, kitchen waste contains a large amount of organic nitrogen substances, which are converted into ammonia nitrogen during the fermentation process. When the concentration of ammonia nitrogen is too high, it may inhibit the metabolism of microorganisms, thereby reducing the efficiency of anaerobic fermentation and even causing fermentation failure. This phenomenon is called "ammonia inhibition", which not only affects the stability of the fermentation process but also reduces the efficiency of biogas production. In addition, existing technologies are still insufficient in the management and control of nitrogen sources and have failed to effectively solve the problem of ammonia inhibition.

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0029] like Figure 1 As shown, a kitchen waste ammoniation treatment system provided by an embodiment of the present invention includes an equipment base plate 1, and an ammoniation reaction tank 5 is provided on the surface of the equipment base plate 1. The kitchen waste that has been crushed and cleaned is subjected to three-phase centrifugal separation to obtain an aqueous phase (hereinafter referred to as "material"), which is transported to the interior of the ammoniation reaction tank 5 by an external centrifugal pump. An agitator 6 is installed on the surface of the ammonia reaction tank 5. The agitator 6 is composed of multiple groups of stirring blades, a drive motor and a support frame. It is intended to fully mix the aqueous phase and other liquid solvents inside the ammonia reaction tank 5 through efficient mechanical stirring to improve the reaction efficiency and the uniformity of the substance.

[0030] A strain activation box 2 is provided on the surface of the bottom plate 1 of the equipment, and a first pumping pump 3 is provided between the strain activation box 2 and the ammoniation reaction tank 5. One port of the first pumping pump 3 is connected to the strain activation box 2 through a feed pipe, and the other port of the first pumping pump 3 is connected to the ammoniation reaction tank 5 through a feed pipe. The interior of the strain activation box 2 is designed to activate and culture the proliferated strains, and provide suitable temperature, humidity and nutritional conditions to promote the growth and reproduction of the strains. The prepared strains will be transported to the interior of the ammoniation reaction tank 5 through the first pumping pump 3 and fully mixed with the materials. These strains are used to accelerate the ammoniation process and improve the efficiency of the ammoniation reaction and the quality of the product. During the mixing process, it is preferred to keep the reaction temperature of the strains and the materials at 35-36°C and the reaction time at 7-10 days to ensure the best reaction effect and strain activity.

[0031] The strain activation box 2 is a special device with constant temperature, constant humidity and gas circulation functions, which can provide a stable growth environment for the proliferation of strains. It is equipped with a temperature control device and a humidification system to ensure that the strains can receive sufficient nutrition and suitable growth conditions during the activation and cultivation process, thereby maximizing the activity and reproduction efficiency of the strains. In addition, the design of the strain activation box combines mature existing technologies and adopts advanced bioreactor technology to ensure the uniform distribution of gas and nutrients, thereby improving the growth rate and yield of the strains. This equipment has been widely used in fields such as microbial cultivation and fermentation engineering. It has good stability and reliability and can meet the growth needs of different types of strains.

[0032] An alkali liquid storage tank 7 is provided on the surface of the equipment base plate 1, and a first metering pump 8 is provided between the alkali liquid storage tank 7 and the amination reaction tank 5. One port of the first metering pump 8 is connected to the amination reaction tank 5 via an infusion tube, and the other port of the first metering pump 8 is connected to the alkali liquid storage tank 7 via an infusion tube. A sufficient amount of alkali liquid is stored in the alkali liquid storage tank 7.

[0033] After the bacterial strain is placed into the ammoniation reaction tank 5 and a suitable reaction time has elapsed, the first metering pump 8 delivers alkali solution from the alkali solution storage tank 7 into the ammoniation reaction tank 5, thereby maintaining the pH value of the material in the ammoniation reaction tank 5 between 6.5 and 7.5. This pH environment facilitates effective reaction and thorough mixing of the bacterial strain and the material.

[0034] An ammonia stripping box 17 is provided on the surface of the equipment base plate 1, and a second pumping pump 16 is provided between the ammonia stripping box 17 and the amination reaction tank 5. One port of the second pumping pump 16 is connected to the ammonia reaction tank 5 through a feed pipe, and the other port of the second pumping pump 16 is connected to the ammonia stripping box 17 through a feed pipe.

[0035] A second metering pump 9 is provided between the alkali solution storage tank 7 and the ammonia stripping tank 17 , one port of the second metering pump 9 is connected to the alkali solution storage tank 7 through an infusion pipe, and the other port of the second metering pump 9 is connected to the ammonia stripping tank 17 through an infusion pipe.

[0036] After fully reacting with the bacterial strain, the material is pumped into an ammonia stripping tank 17 via a second pump 16. A predetermined amount of lye is then added to the tank 17 using a second metering pump 9 to adjust the pH of the material to 9-10. Subsequently, the material, with a pH in the range of 9-10, is stripped of its contents with ammonia in the stripping tank 17. The stripping gas-liquid ratio is 2000-2500, and the reaction time is 30-40 minutes.

[0037] A stripping gas-to-liquid ratio of 2000-2500 refers to the flow ratio of gas (such as air or inert gas) to liquid during the ammonia stripping process. This ratio represents the relationship between the volume of gas stripped and the volume of liquid treated per unit time. A higher gas-to-liquid ratio increases the contact area between the gas and liquid, improving ammonia removal efficiency, shortening reaction time, and effectively utilizing energy, thereby reducing operating costs. Therefore, a reasonable gas-to-liquid ratio is crucial for optimizing the ammonia removal process and enhancing overall treatment effectiveness.

[0038] The ammonia stripping box 17 is a specialized device primarily used to remove ammonia from liquids, reducing their concentration and improving their quality. This equipment typically utilizes gas-liquid contact technology. By introducing a gas other than ammonia (such as air or an inert gas) into contact with the liquid at a specific pressure and temperature, the ammonia volatilizes from the liquid phase and is removed. The design of the ammonia stripping box ensures sufficient gas-liquid contact, improving ammonia removal efficiency.

[0039] Ammonia stripping technology is a mature, established technology widely used in wastewater treatment, chemical engineering, and environmental protection. In many industrial and agricultural processes, ammonia removal is essential to prevent environmental pollution and resource waste. This technology, honed through years of research and practice, demonstrates excellent operational performance and economic benefits, effectively meeting the demands of industrial production.

[0040] A pH adjustment box 13 is provided on the surface of the equipment base plate 1, and a third pumping pump 18 is provided between the pH adjustment box 13 and the ammonia stripping box 17. One port of the third pumping pump 18 is connected to the ammonia stripping box 17 through a feed pipe, and the other port of the third pumping pump 18 is connected to the pH adjustment box 13 through a feed pipe.

[0041] An acid liquid storage tank 12 is disposed on the surface of the pH adjustment tank 13, and a third metering pump 11 is disposed between the acid liquid storage tank 12 and the pH adjustment tank 13. One port of the third metering pump 11 is connected to the acid liquid storage tank 12 via an infusion tube, and the other port of the third metering pump 11 is also connected to the pH adjustment tank 13 via an infusion tube. A sufficient amount of acid liquid is stored in the acid liquid storage tank 12.

[0042] The ammonia-stripped material is then pumped into the pH adjustment tank 13 via the third pump 18. Subsequently, the third metering pump 11 draws a preset amount of acid from the acid storage tank 12 and transfers it to the pH adjustment tank 13 to adjust the pH of the material within to between 6 and 7. This process ensures the material maintains an appropriate pH for subsequent processing, thereby improving the efficiency and effectiveness of subsequent reactions.

[0043] A material temporary storage tank 14 is provided on the surface of the equipment base plate 1, and a fourth extraction pump 19 is provided between the material temporary storage tank 14 and the pH adjustment box 13. One port of the fourth extraction pump 19 is connected to the pH adjustment box 13 through a feed pipe, and the other port of the fourth extraction pump 19 is connected to the material temporary storage tank 14 through a feed pipe.

[0044] An anaerobic fermentation vessel 15 is provided on the surface of the equipment base plate 1, and a fifth feed pump 20 is provided between the anaerobic fermentation vessel 15 and the material temporary storage tank 14. One port of the fifth feed pump 20 is connected to the material temporary storage tank 14 through a feed pipe, and the other port of the fifth feed pump 20 is connected to the anaerobic fermentation vessel 15 through a feed pipe.

[0045] The material, after its pH is adjusted to 6-7, is pumped by the fourth pump 19 into the temporary material storage tank 14. The material remains in the temporary material storage tank 14 for three days to allow for sufficient reaction. When the dissolved oxygen level drops below 0.3, the material is pumped by the fifth pump 20 into the anaerobic fermentation chamber 15 for anaerobic fermentation to generate biogas.

[0046] In one embodiment of the present invention, the first pumping pump 3 , the second pumping pump 16 , the third pumping pump 18 , the fourth pumping pump 19 and the fifth pumping pump 20 are all installed on the equipment base plate 1 or other dedicated mounting frame.

[0047] The specific process of the present invention is as follows: First, the aqueous phase obtained by three-phase centrifugal separation of the kitchen waste that has been crushed and decontaminated is transported into the ammonia reaction tank 5 by a centrifugal pump. In the ammonia reaction tank 5, the agitator 6 fully mixes the material and the input bacteria to ensure that the reaction temperature is maintained at 35-36°C and the reaction time is controlled at 7-10 days. Subsequently, the material that has been treated with ammonia stripping is transported to the ammonia stripping box 17 by the second pumping pump 16, and a preset amount of alkali solution is added to the ammonia stripping box 17 using the second metering pump 9 to adjust the pH value of the material to 9-10. Next, the ammonia stripping box 17 performs ammonia stripping treatment on the material with a pH value in the range of 9-10, the stripping gas-liquid ratio is 2000-2500, and the reaction time is 30-40 minutes.

[0048] The treated material is pumped to the pH adjustment tank 13 via the third pump 18. The third metering pump 11 draws a preset amount of acid from the acid storage tank 12 to adjust the pH of the material to 6-7. The material is then pumped to the temporary storage tank 14 via the fourth pump 19, where it remains for three days to allow for sufficient reaction. When the dissolved oxygen level drops below 0.3, the material is pumped to the anaerobic fermentation tank 15 via the fifth pump 20 for anaerobic fermentation to produce biogas.

[0049] In summary, the use of ammonia reactor 5 effectively converts organic nitrogen in food waste into ammonia nitrogen. This process not only improves nitrogen utilization but also reduces the risk of ammonia inhibition during anaerobic fermentation. Furthermore, culture activation tank 2 provides a stable growth environment for the proliferating bacteria, ensuring a sufficient and efficient reaction.

[0050] The design of the pH adjustment tank 13 allows for precise control of the pH of the material, thereby promoting microbial growth and the production of volatile fatty acids (VFAs). The ammonia stripping tank 17 further reduces the inhibitory effect of ammonia on microorganisms by removing excess ammonia, ensuring smooth anaerobic fermentation. Finally, the provision of the material temporary storage tank 14 allows the material to fully react and remain before entering the anaerobic fermenter, thereby optimizing gas production efficiency.

[0051] The synergistic effect of various structures not only effectively converts organic nitrogen in kitchen waste into ammonia nitrogen, reducing the risk of ammonia inhibition in anaerobic fermentation, but also improves the gas production efficiency of anaerobic fermentation, providing an innovative solution for the resource utilization of kitchen waste.

[0052] In this embodiment, a sixth feed pump 21 is installed on the surface of the equipment base plate 1, and one port of the sixth feed pump 21 is connected to the feed pipe between the second feed pump 16 and the amination reaction tank 5 through the feed pipe, and the other port of the sixth feed pump 21 is connected to the amination reaction tank 5.

[0053] The reflux system is located between the discharge of the ammonia reaction tank 5 and the ammonia stripping box 17. Its primary function is to effectively utilize the large amount of bacterial strains contained in the discharge of the ammonia reaction tank 5. As the discharge of the ammonia reaction tank 5 proceeds, some bacterial strains may be lost with the material, resulting in a decrease in the bacterial strain concentration within the ammonia reaction tank 5. By recirculating the discharge material into the ammonia reaction tank 5, the bacterial strains within the tank can be effectively replenished, ensuring sufficient bacterial strains during the reaction process.

[0054] This reflux design not only improves the system's bacterial strain utilization rate, but also promotes the progress of the ammonia reaction. Since the bacterial strain plays a key catalytic role in the reaction, sufficient bacterial strains can accelerate the rate of the ammonia reaction, thereby more effectively converting organic nitrogen into ammonia nitrogen. This process helps to reduce the risk of ammonia inhibition and provide a more ideal environment for subsequent anaerobic fermentation. In addition, the setting of the reflux system also helps to stabilize the environmental conditions in the ammonia reaction tank 5 and further optimize the overall treatment effect. By realizing the recovery and reuse of bacterial strains, the overall efficiency of the system is improved, creating better conditions for the resource utilization of kitchen waste.

[0055] In this embodiment, a digital display temperature controller 4 is installed on the side of the amination reaction tank 5, and a heating belt 22 is installed on the outside of the amination reaction tank 5.

[0056] The digital display temperature controller 4 can monitor the temperature in the ammonia reaction tank 5 in real time, providing important temperature data for the reaction process. Through precise temperature control, the reaction can be ensured to proceed within the appropriate range, thereby improving the activity of the strain and the reaction efficiency.

[0057] Heat heating tape 22 is installed to maintain the temperature of the amination reaction tank 5, preventing reaction temperature fluctuations caused by changes in the external ambient temperature. The heat heating tape provides additional heat in low-temperature environments, ensuring the stability of the amination reaction. This design helps maintain the optimal temperature range for the amination reaction, thereby promoting the conversion of organic nitrogen to ammonia nitrogen and reducing the risk of ammonia inhibition.

[0058] In summary, the combined application of the digital display temperature controller 4 and the heating tape 22 ensures the temperature stability in the amination reaction tank 5, provides a guarantee for the efficient progress of the reaction, thereby improving the efficiency of the overall treatment system and promoting the resource utilization of kitchen waste.

[0059] In this embodiment, an ammonia collection box 10 is installed on the surface of the ammonia stripping box 17, and the ammonia collection box 10 is connected to the ammonia stripping box 17 via a gas pipe. After the ammonia stripping treatment, the ammonia nitrogen concentration in the material is greatly reduced, which not only effectively reduces the inhibitory effect of ammonia on subsequent anaerobic fermentation, but also optimizes the fermentation environment.

[0060] Ammonia gas generated during the stripping process is captured by a collection box 10 and introduced into a collection system via a gas pipeline. Within the collection system, the stripped ammonia reacts with acid to form ammonium salts, converting the ammonia into usable chemical raw materials. The generation of ammonium salts not only improves resource utilization but also provides potential for subsequent economic benefits.

[0061] By effectively collecting and converting ammonia into valuable chemical raw materials, the combined application of the ammonia stripping box 17 and the ammonia collection box 10 not only improves the overall efficiency of the system, but also realizes resource recovery and economic benefits in the process of food waste treatment, and promotes sustainable development.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
