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 present invention discloses a toggle switch group lock head assembly with a positioning device, comprising a lock head, a lock core and a key matched with the lock core, the lock core is arranged inside the lock head, and a handle, a lock fork and a mounting seat are sequentially sleeved on the outside of the lock head from top to bottom, the handle and the lock fork are connected to the lock head through axial serrations, a retractable lock tongue is arranged at the bottom of the lock core, a lock tongue groove matched with the lock tongue is provided on the lock head and the mounting seat, a positioning hole is arranged inside the mounting seat, a positioning steel ball, a spring A and a set screw C are arranged in the positioning hole from inside to outside, and a positioning groove matched with the positioning steel ball is provided on the outside of the lock head. The toggle switch group lock head assembly of the present invention is composed of a lock head, a lock core, a lock tongue, a key, a handle, a lock fork and a mounting seat, and has a simple structure. The lock tongue is driven to retract and retract by twisting the key, thereby changing the state of the lock head assembly, realizing the control of the toggle switch group, and improving the reliability of the lock switch action.

The present invention discloses a pollutant type analysis and detection device for sampling at different water depths, including a pollutant detection main body, wherein the pollutant detection main body includes a detection box, a chamfered surface is provided at the upper left corner of the detection box, a touch display panel is installed on the chamfered surface, and a drain hose located at the left end is fixedly connected to the bottom surface of the detection box; water samples are temporarily stored by splitting the detection components, so that the pollutant detection main body can detect the water samples, and a sampler can be driven to operate by a water intake depth regulator, and the water intake depth can be changed by the operation of the sampler, thereby achieving the purpose of sampling at different depths in the water body, ensuring that the detection result can reflect the condition of the water body as a whole, and the running sampler will not cause disturbances between water layers, so that the water quality of the water sample taken can better represent the water quality of the sampling water layer, ensuring that the detection result can more accurately reflect the condition of the water body, and improving the practicability of the device.

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.
