Technical Field

[0001] This utility model relates to the technical field of dewaxing kettle equipment, and in particular to a waste heat recovery and utilization device for a dewaxing kettle. Background Technology

[0002] Steam dewaxing kettles are industrial devices used to remove wax layers. They typically use steam to heat the wax layer, melting it and allowing it to be removed. This process generates a significant amount of waste heat. Effective recovery and utilization of this waste heat can improve energy efficiency and reduce energy costs. Waste heat recovery and utilization devices for steam dewaxing kettles can help industrial processes utilize energy resources more efficiently, reduce energy costs, and minimize environmental impact.

[0003] In an existing dewaxing kettle, the wax layer is heated by steam, and the steam contains wax. If the waste heat is directly recovered and utilized, the wax and water mixture is likely to remain on the inner wall of the steam pipe, requiring timely cleaning. If not cleaned in time, the steam pipe is likely to become blocked, affecting the subsequent passage of steam. Moreover, cleaning the steam pipe is time-consuming and laborious, affecting the work efficiency of the staff. Therefore, a waste heat recovery and utilization device for the dewaxing kettle is proposed to solve the above problems. Utility Model Content
