Description

Technical Field

[0001] This utility model relates to the field of pesticide pulverization and drying technology, specifically a pesticide airflow pulverization and drying process device. Background Technology

[0002] As is well known, in traditional pesticide production processes, especially those involving air jet milling, air compressors are typically used to provide high-pressure gas. However, in practice, compressed air contains a large amount of moisture and oil. If these components are not removed, they will directly affect the subsequent milling effect and the quality of the final product. Therefore, compressed air is generally treated with a refrigerated dryer to remove moisture, and then further purified by a filter to ensure the quality of the compressed air entering the air jet mill. Refrigerated dryers remove moisture from compressed air by lowering the temperature. While this method is effective, it causes the compressed air temperature to drop significantly, approaching or even below ambient temperature. Low-temperature compressed air is unsuitable for materials that require heating to promote drying. Freeze-drying is unsuitable for most applications because it lacks sufficient heat to evaporate moisture from materials. To compensate for the low compressed air temperature caused by freeze-drying, additional high-power heat exchangers must be added after the freeze-drying and filtration steps if the compressed air needs to be heated. This not only increases the investment cost of the equipment but also significantly increases the overall energy consumption of the system. Considering the rising trend of energy costs, this is undoubtedly an important factor. Air compressors generate a large amount of waste heat during operation, which is usually directly discharged into the environment without being effectively utilized. This means that valuable resources that could have been used to improve system energy efficiency are wasted. Therefore, it is necessary to propose a solution to this technical problem.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a pesticide airflow pulverization and drying process device, which has the following beneficial effects:

[0014] This pesticide airflow pulverization and drying process device utilizes the waste heat generated during the operation of an air compressor. Through a heat exchange system, this heat is recovered and used to heat the cryogenically dried compressed air. This not only solves the problem of excessively low compressed air temperature caused by cooling in traditional processes but also avoids the need for additional high-power heat exchangers for heating. This achieves efficient resource utilization. Compared to the traditional method of consuming a large amount of energy to heat the compressed air, by cleverly using the heat generated by the air compressor itself as a heat source, the system's total energy consumption is significantly reduced, helping to lower operating costs and contributing to environmental protection. By reducing carbon emissions from energy consumption, the optimized heat exchange process ensures that the compressed air entering the air jet mill is kept at a suitable high temperature, which is conducive to accelerating the evaporation of moisture in the material, thereby improving the efficiency of grinding and drying. The more efficient drying process also helps to improve the quality of the final product and reduce quality problems caused by residual moisture. It integrates multiple functions such as air compression, freeze drying, heat recovery and reuse, air jet milling, separation and dust removal into one complete production line. The integrated design not only simplifies the production process, but also reduces the complexity of the connection between each link and improves the stability and reliability of the entire system.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2This utility model relates to a pesticide airflow pulverization and drying process device, comprising an air compressor 1, a refrigerated dryer 2, a heat exchange system, an airflow pulverizer 3, and auxiliary components. The refrigerated dryer 2 is connected to the air compressor 1. The heat exchange system includes a waste heat recovery module 4 and a circulating heating module. The waste heat recovery module 4 is connected to the radiator of the air compressor 1. The circulating heating module connects the refrigerated dryer 2 and the waste heat recovery module 4. The airflow pulverizer 3 is connected to the circulating heating module. The auxiliary components include a separator 5, a dust collector 6, and an induced draft fan 7. The separator 5, the dust collector 6, and the induced draft fan 7 are sequentially piped to the outlet end of the airflow pulverizer 3.

[0020] To further ensure efficient heat recovery from the air compressor 1 radiator, in this design, the waste heat recovery module 4 is a plate heat exchanger or a shell-and-tube heat exchanger. Its input end is connected to the radiator of the air compressor 1, and its output end transfers the recovered heat to the circulating heating module through pipelines. This ensures efficient heat recovery from the air compressor 1 radiator and effective transfer of it to the low-temperature dry air requiring heating, thereby improving the overall system's energy efficiency ratio.

[0021] To further ensure that the compressed air entering the airflow pulverizer 3 reaches the ideal temperature, in this scheme, the circulating heating module includes a circulating pipeline 8 and a compensating heater 9. The circulating pipeline 8 guides the low-temperature drying air from the refrigerated dryer 2 to the waste heat recovery module 4 for heat exchange. The compensating heater 9 adjusts the air temperature to 40~50℃ to ensure that the compressed air entering the airflow pulverizer 3 reaches the ideal temperature, so as to promote the effective pulverization and drying process of materials. At the same time, the compensating heater 9 compensates for any possible heat deficiency and ensures operational stability.

[0022] To further enhance the airflow velocity and impact force within the airflow pulverizer 3, in this design, a high-speed airflow nozzle is provided inside the connection between the air inlet of the airflow pulverizer 3 and the output end of the circulating heating module. The high-speed airflow nozzle enhances the airflow velocity and impact force within the airflow pulverizer 3, enabling the material to be more effectively crushed into fine powder. Furthermore, the high-temperature gas accelerates moisture evaporation, thereby improving pulverization and drying efficiency.

[0023] To further and more effectively separate the pulverized material powder from the gas, in this solution, the separator 5 is a cyclone separator 5, and the dust collector 6 is a bag filter 6. The bag filter 6 can efficiently separate the pulverized material powder from the gas and remove the tiny particles, ensuring the purity and quality of the final product, while also protecting subsequent equipment from dust pollution.

[0024] To further provide a stable and reliable pressure source, in this solution, the air compressor 1 is a screw compressor. The screw compressor can provide a stable and reliable pressure source to meet the requirements of the entire system for compressed air quality and pressure. At the same time, the screw compressor has a compact structure, stable operation, and simple maintenance.

[0025] This invention relates to a pesticide airflow pulverizing and drying process device. In operation, air is first compressed by an air compressor, generating heat during compression and raising the temperature of the compressed air to 70-80 degrees Celsius. This high-temperature, high-pressure compressed air is then guided to a refrigerated dryer for preliminary cooling and dehydration. After this process, the temperature of the compressed air drops below 10 degrees Celsius, and its moisture content is significantly reduced. Next, the low-temperature dried compressed air is introduced into the waste heat recovery module of the heat exchange system. Simultaneously, the heat generated by the air compressor is also guided into this module, where the low-temperature dried air exchanges heat with the high-temperature heat from the compressor radiator, causing the temperature of the dried air to rise back to a suitable operating temperature of approximately 40-50 degrees Celsius. The high-power heat exchanger that previously required additional energy consumption is no longer necessary. The heated compressed air then flows into the airflow pulverizer, where it not only serves as a power source to drive the high-speed airflow nozzles but also as a crucial medium for material drying. Inside the airflow pulverizer, the material is pulverized into fine powder by the impact of the high-speed airflow. Simultaneously, due to the presence of hot air, the moisture in the material evaporates rapidly, achieving integrated pulverization and drying operations. The mixture exiting the air jet mill, containing pulverized material powder and any remaining fine particles, then enters a series of auxiliary components, including a cyclone separator, a bag filter, and an induced draft fan. These devices work in sequence to effectively separate the material powder from the gas and remove dust and impurities, ensuring the purity and quality of the final product. The hot air compressed from the air compressor is not directly introduced into the refrigerated dryer. Instead, it is introduced into the waste heat recovery module radiator of the heat exchange system, where it exchanges heat with the cold air exiting the refrigerated dryer. This process cools the hot air entering the dryer and warms the cold air exiting it. This method not only effectively reduces the temperature of the air at the front end of the refrigerated dryer, enhancing the refrigeration effect, but also fully utilizes existing thermal energy resources, forming a highly efficient energy cycle system to achieve energy conservation and emission reduction.
