A non-ferrous metal powder production device based on secondary vaporization heating
By using a vaporizer body consisting of a solid outer tube and a porous inner liner in the metal distillation powdering system, a continuous gas film is formed to block droplet contact and provide a secondary vaporization heat source, solving the problem of tube wall scaling and blockage caused by metal droplet entrainment, and improving powder purity and production continuity.

AI Technical Summary
Technical Problem
In existing metal distillation powder production systems, metal droplet entrainment leads to scaling and blockage of the tube walls, affecting the purity of the metal powder and the continuity of production.
Method used
The vaporizer body consists of a solid outer tube and a porous inner liner. A continuous gas film is formed in the porous inner liner by a protective gas to prevent the metal droplets from contacting the tube wall. The heating components provide a secondary vaporization heat source to completely vaporize the droplets.
Benefits of technology
It achieves a non-contact anti-scalding effect, improves the purity and yield of metal powder, avoids pipeline blockage, and ensures the stability and efficiency of production.

Abstract
本发明涉及有色金属冶炼与粉末制备技术领域，具体是涉及一种基于二次汽化加热的有色金属制粉设备，包括：蒸馏炉和汽化炉本体，汽化炉本体包括管壁为实心的外管以及同轴套设于外管内部的多孔内胆，外管的内壁与多孔内胆的外壁之间形成有环形气室；加热组件，贴合设置于外管的外壁上，用于向汽化炉本体的内腔提供汽化热源；供气管路，与环形气室连通；通过设置管壁为实心的外管与多孔内胆组成的汽化炉本体，解决了金属液滴撞击管壁结疤的核心问题。通过保护气体透过多孔内胆向内渗出，在内胆内腔表面形成了一层连续的无形动态气膜，在流体力学上彻底阻断了重金属液滴与内胆管壁的物理接触，实现了无接触防结疤的效果。
