AI Technical Summary

Technical Problem

In existing thermal oil heaters, the condensate of low-boiling-point substances flows back to the main circulation pipeline system, resulting in reduced thermal conductivity and decreased thermal efficiency. It may also cause pressure fluctuations and flow instability, affecting the stable operation of the heater.

Method used

Design a low-boiling-point substance collection device for a thermal oil heater, including a low-boiling-point substance riser, a condenser, and a condensate downcomer. The low-boiling-point substance is introduced into the condenser through the exhaust port at the top of the expansion tank and cooled into condensate. The condensate is then collected into a recovery tank through the condensate downcomer. The device is combined with a cooling fan and heat dissipation fins to accelerate cooling and prevent the low-boiling-point substance from flowing back.

Benefits of technology

It effectively prevents the backflow of low-boiling-point condensate, improves the heat transfer performance of heat transfer oil, ensures stable operation of the heating furnace, reduces environmental pollution, and achieves high efficiency, energy saving, and emission reduction.
