AI Technical Summary
Existing technologies lack a recycling system for high-temperature condensate, leading to energy waste and pipeline wear, which is particularly pronounced in extremely cold regions.
Design a waste steam recovery device for heating coal conveying trestle in extremely cold regions. High-temperature condensate is collected through a dedicated pipeline and heat is transferred to the air inside the heater shell through a dual-channel heat exchange tube for heating. The device combines inclined pipes and condensate return water device to cool the condensate and recover waste heat. Rotary turbulence fan blades and modular heat dissipation fins are used to improve heat exchange efficiency, and intelligent temperature-controlled electric heating tape is used to prevent freezing.
It enables efficient recovery of condensate heat for factory heating, reduces energy waste, lowers the risk of pipeline wear, and ensures stable operation of the system in extremely cold environments.
