This application relates to the field of air purification and discloses a wet vortex step-flow dust collector, which falls under the technical field of air purification. The dust collector includes an outer shell and, sequentially arranged inside, an air inlet assembly, a humidification assembly, a separation assembly, and an exhaust assembly. The air inlet assembly increases the initial velocity of the airflow through a narrow-diameter guide pipe. The humidification assembly utilizes the local negative pressure generated by the inclined drain holes on the distributor head to automatically draw in liquid and shear it into fine droplets, achieving efficient dust collection. The separation assembly adopts a variable cross-section flow channel design, gradually reducing the airflow passage space to compensate for momentum loss during rotation, maintaining high centrifugal acceleration to ensure the liquid film adheres to the wall. The cooling airflow from the drive motor is guided to the recovery chamber outside the main flow pipe, forming a directional guiding airflow to assist in wastewater recovery. The exhaust assembly induces liquid film peeling through the stepped inner wall and, utilizing the controlled pressure difference between the recovery chamber and the main flow channel, actively draws the liquid film into the recovery chamber through the distributor holes.

The invention relates to the technical field of yellow phosphorus tail gas treatment, and particularly discloses a yellow phosphorus tail gas purification device which comprises a magnetization pretreatment unit and a deep catalytic oxidation unit which are sequentially arranged in the tail gas flowing direction and communicate with each other. The deep catalytic oxidation unit comprises an electric heating catalytic reactor, a plurality of layers of electric heating catalytic nets which are arranged at intervals are arranged in the electric heating catalytic reactor, the electric heating catalytic nets are perpendicular to the flow direction of the tail gas, and all the layers of electric heating catalytic nets are electrically connected through conductive structures. The yellow phosphorus tail gas treatment device is optimized and improved, absolute dependence of traditional spraying washing on liquid drop atomization quality can be effectively avoided, the problems that a nozzle is blocked and a flow field is uneven are solved, and deep removal of difficult-to-treat components such as PH3 is achieved.

A production apparatus and processing method for thin-walled micro-pitch high-efficiency heat exchange tubes are disclosed, relating to the field of high-efficiency heat exchange tube production technology. The production apparatus of this invention includes a frame, a tie rod, a core head, a lead screw module, a servo motor, a claw plate, and a rolling head. One end of the tie rod is mounted on the frame and parallel to the bottom of the frame. The end of the tie rod away from the frame is connected to the core head. A servo motor is mounted on the end of the frame away from the tie rod. The output end of the servo motor is connected to the lead screw module. A claw plate is mounted on the lead screw module. The rolling head is mounted on the frame. The high-efficiency heat exchange tubes produced by the method of this invention are of great significance for energy saving, water saving, saving operating costs, and reducing reinvestment. They also have advantages such as low resistance, small size, and material saving.
