AI Technical Summary
During the steam purge process of existing tank stereoscopic mirrors, the purge area of the single-hole nozzle is insufficient, resulting in the unclear view mirror. Although the purge area of the porous nozzle increases under the same pressure, the effect is limited.
A steam jet nozzle is designed, which contains multiple columnar channels with decreasing diameters and inclined diameters. Combined with a pressure transmitter and a digital display instrument, the pneumatic switch shutoff valve is automatically or manually controlled through the PLC control system to achieve strong steam purging.
Ensure the tank stereo glass is clear, reduce labor costs, and ensure the normal operation of the equipment.
