Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, and in particular to a powder flow cooling system. Background Technology

[0002] During fertilizer production, because the initial temperature is high when the fertilizer is first produced, it is necessary to physically cool the newly produced fertilizer in order to preserve it. In existing technologies, fluid coolers are typically used to cool fertilizers. These coolers are equipped with multiple heat dissipation plates containing cooling water. The cooled water is then transported to a cooling tower, where it exchanges heat with the pipes containing the cooling water, thus lowering its temperature. The cooled water is then recycled back to the fluid cooler to continue cooling the fertilizer. However, current solutions only use a single cooling tower, which is sometimes insufficient to adequately reduce the cooling water temperature. Furthermore, the cooling water is prone to freezing in winter, hindering the normal cooling operation of the fluid cooler. Therefore, a more efficient fluid cooling system is urgently needed to address these technical problems. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned technologies, such as the low cooling efficiency of a single cooling tower and the tendency of cooling water to freeze, this utility model provides a powder flow cooling system.

[0004] To achieve the above objectives, this utility model provides a powder flow cooling system, including a fluid cooler, a first cooling tower, and a second cooling tower. The fluid cooler is equipped with multiple sets of heat-conducting plates and antifreeze pipes. Each heat-conducting plate has a cavity and through holes at both ends that connect to the cavity. Any adjacent heat-conducting plates are connected by the antifreeze pipes. The fluid cooler also has an antifreeze inlet and an antifreeze outlet. The heat-conducting plates at the beginning and end are respectively connected to the antifreeze inlet and the antifreeze outlet. The first cooling tower and the second cooling tower are connected, and the first cooling tower and the second cooling tower are respectively connected to the antifreeze inlet and the antifreeze outlet.

[0005] As an improvement of this utility model, both the first cooling tower and the second cooling tower are equipped with antifreeze cooling pipes, and the first cooling tower and the second cooling tower are connected to the antifreeze inlet and the antifreeze outlet respectively through the antifreeze cooling pipes.

[0006] As an improvement of this utility model, it further includes an axial flow fan, cooling water pipes, and a water pump. The axial flow fan is respectively installed on the top of the first cooling tower and the second cooling tower, and the cooling water pipes are installed inside the first cooling tower and the second cooling tower. The water pump is located below the first cooling tower and the second cooling tower and is connected to the cooling water pipes. The water pump draws water to be sent into the cooling water pipes, and the axial flow fan delivers airflow to generate water mist that diffuses to the surface of the antifreeze cooling pipes.

[0007] As an improvement of this utility model, it also includes a silicon phosphate crystal medicine container, which is installed on the cooling water pipe and is used to mix silicon phosphate crystal powder and inject it into the tap water of the cooling water pipe.

[0008] As an improvement of this utility model, a buffer tank is also connected between the antifreeze outlet and the first cooling tower.

[0009] As an improvement of this utility model, it also includes a dehumidifier, a blower, and a dehumidification water tower. The blower and the dehumidification water tower are connected to the water inlet of the dehumidifier. The fluid cooler is also provided with at least one dehumidification port, and the dehumidification end of the dehumidifier is connected to the dehumidification port.

[0010] The beneficial effects of this utility model are as follows: Compared with the prior art, the powder flow cooling system provided by this utility model includes a fluid cooler, a first cooling tower, and a second cooling tower. The fluid cooler is equipped with multiple sets of heat-conducting plates and antifreeze pipes. The heat-conducting plates have cavities and through holes at both ends that connect to the cavities. Any adjacent heat-conducting plates are connected by antifreeze pipes. The fluid cooler also has an antifreeze inlet and an antifreeze outlet.

Detailed Implementation

[0013] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0014] In the following description, specific examples are given to provide a more in-depth understanding of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0015] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0016] Please see Figure 1 This utility model discloses a powder flow cooling system, comprising a fluid cooler 1, a first cooling tower 2, and a second cooling tower 3. The fluid cooler 1 contains multiple sets of heat-conducting plates 4 and antifreeze pipes 5. Each heat-conducting plate 4 has a cavity and through holes at both ends connecting to the cavity. Adjacent heat-conducting plates 4 are connected by antifreeze pipes 5. The fluid cooler 1 also has an antifreeze inlet 6 and an antifreeze outlet 7. The heat-conducting plates 4 at the beginning and end are connected to the antifreeze inlet 6 and the antifreeze outlet 7, respectively. The first cooling tower 2 and the second cooling tower 3 are connected, and the first cooling tower 2 and the second cooling tower 3 are connected to the antifreeze inlet 6 and the antifreeze outlet 7, respectively. This utility model provides a more efficient cooling capacity to the fluid cooler 1 by adding a second cooling tower 3. In cooling tower 2, the antifreeze, after absorbing heat from the fertilizer, undergoes initial cooling through heat exchange with cooling water. Subsequently, the pre-cooled antifreeze enters the second cooling tower 3 for further deep cooling, ensuring that the antifreeze is sufficiently cooled. By setting up two cooling towers, not only is the cooling efficiency of the antifreeze improved, but the powder flow is also ensured to be fully cooled in the fluid cooler 1, thereby effectively preventing the powder from caking, deteriorating, or being damaged due to high temperatures. In addition, by adjusting the cooling water volume or flow rate in the first cooling tower 2 and the second cooling tower 3, the cooling temperature of the antifreeze can be flexibly controlled to adapt to the cooling requirements of different powder materials. The entire system has a compact structure, is easy to operate, and greatly improves the efficiency and stability of powder flow cooling.

[0017] In this embodiment, both the first cooling tower 2 and the second cooling tower 3 are equipped with antifreeze pipes 5. The first cooling tower 2 and the second cooling tower 3 are connected to the antifreeze inlet 6 and the antifreeze outlet 7 respectively through the antifreeze pipes 5, so as to realize the circulation of antifreeze between the two cooling towers, thereby further improving the cooling efficiency. In the first cooling tower 2, the cooling water exchanges heat with the antifreeze through the cooling water pipe 10, carrying away the heat in the antifreeze and initially reducing the temperature of the antifreeze. Subsequently, the antifreeze flows into the second cooling tower 3, where it exchanges heat with the cooling water again through the cooling water pipe 10 to achieve deep cooling and ensure that the antifreeze can be fully cooled down.

[0018] In this embodiment, a buffer tank 12 is also connected between the antifreeze outlet 7 and the first cooling tower 2. The buffer tank 12 can effectively slow down the flow rate of the antifreeze when it flows out of the fluid cooler 1, preventing the fluid pressure from being unstable due to excessive flow rate. At the same time, it can also perform preliminary separation of the gas contained in the antifreeze, removing impurities and air bubbles, ensuring that the antifreeze is in a gas-free state before entering the first cooling tower 2. At the same time, when the antifreeze enters the buffer tank 12, it can also play a role in balancing the temperature difference, preventing the pipeline from expanding or contracting due to temperature difference, thus balancing the system pressure, thereby improving cooling efficiency and extending the service life of the equipment. This ensures that the entire cooling system can operate stably while also adapting to pressure changes under different operating conditions, enhancing the flexibility and adaptability of the system.

[0019] In this embodiment, an axial flow fan 9, cooling water pipes 10, and a water pump 11 are also included. The tops of the first cooling tower 2 and the second cooling tower 3 are respectively equipped with axial flow fans 9, and cooling water pipes 10 are installed inside both the first cooling tower 2 and the second cooling tower 3. The water pump 11 is located below the first cooling tower 2 and the second cooling tower 3 and is connected to the cooling water pipes 10. The water pump 11 draws water to the cooling water pipes 10, and the axial flow fan 9 delivers airflow to generate water mist that diffuses onto the surface of the antifreeze cooling pipes 8. The axial flow fan 9 accelerates the diffusion of water mist onto the cooling water pipes 10 and the surrounding airflow, improving heat exchange efficiency and further accelerating the cooling speed of the antifreeze. The working principle of the axial flow fan 9 is to utilize the airflow generated by the rotation of its blades to form... Forced convection is achieved, thereby accelerating the adhesion of water entering through cooling water pipe 10 to the surface of antifreeze cooling pipe 8, and further removing it through axial flow fan 9, improving heat transfer during heat exchange. In the first cooling tower 2, the antifreeze, after initial cooling, still carries some heat. At this time, axial flow fan 9 starts, accelerating the airflow around cooling water pipe 10, allowing the cooling water in cooling water pipe 10 to absorb heat from the antifreeze more quickly, improving heat exchange efficiency. Similarly, in the second cooling tower 3, axial flow fan 9 plays the same role, further accelerating the cooling speed of antifreeze, ensuring that the antifreeze can be sufficiently cooled to meet the cooling requirements of the powder flow. Axial flow fan 9 not only improves cooling efficiency but also makes the entire cooling system more energy-efficient and environmentally friendly.

[0020] In this embodiment, a silicon phosphate crystal container is also included. The silicon phosphate crystal container is installed on the cooling water pipe 10. The silicon phosphate crystal container is used to mix silicon phosphate crystal powder and inject it into the tap water of the cooling water pipe 10. Since tap water often contains various impurities and microorganisms, these impurities and microorganisms may corrode the pipe wall of the cooling water pipe 10 and the coolant pipe, affecting the normal operation and cooling effect of the cooling system. By installing a silicon phosphate crystal container on the cooling water pipe 10, silicon phosphate crystal powder can be mixed and injected into the tap water. Silicon phosphate crystals can slowly dissolve in water and react with metal ions such as calcium and magnesium to release ions with corrosion and scale inhibition effects. These ions can effectively prevent scale and corrosion on the inner wall of the cooling water pipe 10, form soluble complexes, inhibit the production of calcium and magnesium salts, and improve the service life of the cooling water pipe 10. At the same time, it can also react with iron ions to form a protective film on the pipe wall, which can effectively achieve the purpose of corrosion prevention and scale prevention. Secondly, silicon phosphate crystals can also inhibit the growth of microorganisms in the water, maintain the cleanliness of the cooling water, thereby ensuring the stable operation and efficient cooling effect of the cooling system and extending the overall life of the cooling tower.

[0021] In this embodiment, a dehumidifier 13, a blower 14, and a dehumidification tower 15 are also included. The blower 14 and the dehumidification tower 15 are connected to the water inlet of the dehumidifier 13. The fluid cooler 1 is also provided with at least one dehumidification port, and the dehumidification end of the dehumidifier 13 is connected to the dehumidification port. During the powder flow cooling process, due to the influence of ambient humidity, moisture may accumulate inside the fluid cooler 1, causing the material in the fluid cooler 1 to clump when it comes into contact with water. Therefore, this utility model specifically sets up a dehumidifier 13, a blower 14, and a dehumidification tower 15 to jointly solve the problem of material clumping. The blower 14 can be a Roots blower or other type of blower, mainly used to blow the dehumidified air formed by the dehumidifier 13 and the dehumidification tower 15 into the fluid cooler 1, and the dehumidified air carries away the moisture in the fluid cooler 1. The dehumidifier 14 allows dehumidified air to flow quickly through the fluid cooler 1, carrying away the moisture. Simultaneously, the dehumidifier 13, connected to the dehumidification port of the fluid cooler 1 at its dehumidification end, continuously extracts humid air from inside the fluid cooler 1. After dehumidification, the dry air is returned to the fluid cooler 1 via the blower 14, forming a closed dehumidification cycle. This not only effectively reduces the humidity inside the fluid cooler 1, preventing moisture accumulation that could lead to decreased cooling efficiency and equipment damage, but also further improves the cooling effect of the powder flow, ensuring that the powder flow is cooled in the optimal cooling environment. Furthermore, the dehumidification tower 15 provides a stable and continuous source of humidified air for the dehumidifier 13, enhancing the stability and reliability of the entire dehumidification system and making the entire powder flow cooling system more complete and efficient. The advantages of this invention are: 1. By setting up a dual-tower cooling structure, the cooling efficiency is effectively improved, ensuring that the powder flow is fully cooled and preventing powder deterioration or damage caused by high temperature.

[0022] 2. The added buffer tank effectively balances the system pressure, improving the stability of the cooling process and extending the service life of the equipment.

[0023] 3. The axial flow fan further accelerates the cooling speed of the antifreeze, improving the overall cooling efficiency.

[0024] 4. The installation of silicon phosphate crystal tanks effectively prevents scaling and corrosion on the inner wall of cooling water pipes, extends the life of cooling towers, and ensures the stable operation of the cooling system.

[0025] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
