Description

Technical Field

[0001] This invention relates to the field of phosphorus vapor recovery technology, specifically to a phosphorus vapor recovery device. Background Technology

[0002] A phosphorus vapor safe and efficient recovery device, authorized by announcement number CN202575982U, discloses a two-tank bottom-filled water system to prevent phosphorus from contacting air. During production, phosphorus vapor is directly introduced into the water layer, isolating it from air. Phosphorus sinks to the bottom of the tank and continuously enters the phosphorus storage tank, further isolating it from air. Residual phosphorus vapor enters the next phosphorus removal process, achieving full recovery and storage of phosphorus vapor. This invention features a simple structure, easy operation, no phosphorus vapor leakage, good condensation and phosphorus recovery effects, and effectively eliminates phosphorus fire hazards and environmental safety risks.

[0003] The aforementioned device achieves comprehensive phosphorus removal by directly introducing phosphorus vapor into the water layer. However, in actual operation, introducing phosphorus vapor into the water may cause bubbles to form in the water. These bubbles will float to the surface under water pressure, causing the phosphorus vapor to be exposed to the air and resulting in air pollution. In view of this situation, the present invention provides a novel solution. Summary of the Invention

[0041] A connecting shaft 8 is fixed at the fan blade shaft of the fan 7. The connecting shaft 8 is connected to the brake shaft 11 by a transmission belt. A mounting plate 9 is installed at one end of the rotary box 2. The brake shaft 11 is rotatably connected between the mounting plate 9 and one end of the rotary box 2.

The sealing bearing 15 ensures a tight seal between the inlet pipe 16 and the inner wall of the condenser 1, allowing the condensate to smoothly enter and spread in the water distribution pipe 12. The drive device rotates the blade 17, causing the water distribution pipe 12 to rotate. During the rotation, the water distribution pipe 12 throws the condensate out. After being thrown out, the water distribution holes 13 on the surface of the water distribution pipe 12 contact the agitator 18, impacting the condensate to form a water mist, creating an atomization effect that rapidly disperses the phosphorus vapor. Rapid cooling causes partial condensation into liquid. The cooled liquid phosphorus vapor flows into the discharge pipe 5 for recovery. At the same time, phosphorus vapor may still remain after reacting with the condensate. The residual phosphorus vapor needs to be recycled through the recovery device. The drive source 10 drives the fan 7 to rotate through the transmission belt. The airflow generated by the operation of the fan 7 helps to return the phosphorus vapor to the feed pipe 4.
