The present application provides a powder particle processing device and method, which can lower the dew point of the powder particle delivery destination while stabilizing the air volume in the powder particle containing portion. Dry air after dehumidification and heating is supplied into the drying hopper (11), and the powder particles contained in the drying hopper (11) are dried. The delivery pipeline (44) for delivering the dried powder particles to the delivery destination hopper (54) is in communication with the drying hopper (11), and the delivery air flow extending to the delivery destination (54) via the delivery destination hopper (54) flows on the downstream side of the delivery direction in the drying hopper (11). The powder particles contained in the drying hopper (11) are delivered to the delivery destination hopper (54) by making the delivery pipeline (44) generate the delivery air flow in the delivery direction. After delivering the powder particles, the state of opening the delivery pipeline (44) to the atmosphere and stopping the generation of the delivery air flow on the downstream side of the delivery direction of the delivery destination hopper (54) is generated.

This utility model discloses a hot air circulation pipeline diversion and distribution device, relating to the field of pipeline diversion technology. It includes a diversion box with an air inlet on its bottom wall and branch interfaces evenly inserted on its top. Each branch interface has a connecting cylinder fixedly connected to its inner wall, and a crossbar fixedly connected to its inner wall. By incorporating connecting cylinders and connecting balls, this utility model prevents gas backflow during use, ensuring unidirectional hot air flow in the designed direction. This maintains stable airflow and pressure in each branch pipeline, preventing process effects caused by unstable airflow. The device also features threaded sleeves and protruding plates, allowing for quick and easy disassembly of damaged branch interfaces during maintenance. This significantly improves the efficiency of maintenance.

This utility model discloses a yellow phosphorus tail gas combustion system that reduces the generation of acidic substances, belonging to the field of phosphorus chemical processing technology. It solves the problems of high cost, inefficiency, poor stability, and easy secondary pollution associated with existing technologies. The system includes three sequentially connected modules: tail gas pretreatment, combustion, and purification, forming a complete treatment pathway. The pretreatment module uses a centrifugal fan to transport the tail gas, a spray-filter desulfurization tower to remove sulfides, and a high-pressure backflush pipe to ensure stable airflow. The combustion module optimizes the air-fuel ratio, combines flue gas circulation and parameter monitoring to suppress nitrogen oxide generation, and is adapted to boiler waste heat utilization. The purification module is equipped with a waste heat recovery device before electrostatic precipitator to remove impurities. The system achieves desulfurization liquid regeneration and circulation, reduces equipment corrosion and treatment costs, ensures that exhaust gas emissions meet standards, and balances environmental protection and energy utilization efficiency.
