AI Technical Summary
When producing large monomers of water reducer, traditional group steam hydrophobic trays have imbalance in the pressure of steam condensation water, resulting in hedging of the pressure of the heat-tracing pipeline, poor hydrophobic effect, increased steam consumption, and may cause problems such as water accumulation and water hammers, causing equipment damage.
A pipeline heat tracing and hydrophobic device is designed. By connecting each heat tracing pipe separately, a vertical free float ball trap is changed to a separate steam drainage to avoid the pressure hedging of the steam condensate water, and a low drain pipe and straight section pipe are installed in the collection tank to collect condensate and observe the hydrophobic situation.
It improves the heating effect of the pipeline, reduces steam loss, prevents water hammer phenomenon, reduces equipment failure rate, and allows the hydrophobic conditions of each heat-tracing pipeline to be visually observed, and troubleshooting is promptly detected and handled.
