AI Technical Summary

Technical Problem

High-temperature metal vapors condense and adhere in the gas pipeline, causing blockages and hindering the vacuum pyrometallurgical zinc smelting reaction.

Method used

A heat tracing mechanism is installed around the outer periphery of the intake pipe to raise the temperature to the metal melting point, and a turbulence structure is arranged inside the pipe to increase the degree of turbulence, so as to ensure that the metal vapor can smoothly enter the heat exchanger and liquefy.

Benefits of technology

This avoids the condensation and adhesion of metal vapor in the intake pipe, improving the long-term operational reliability of the system and the efficiency of metal reduction.

Abstract

本实用新型公开一种高温金属蒸气冷凝液化装置，包括上下布置的换热器总成和收集池，换热器与收集池之间设有进气管道，进气管道外周设有对进气管道加热的伴热机构；进气管道内还均匀布置有扰流结构。本实用新型在进气管道外周设置有伴热机构用于提升进气管道内温度使管内温度达到金属熔点温度，使进气管道在反应初期时即具有高温环境，确保金属蒸气顺利进入换热器总成内，避免金属蒸气在进气管道时因温度低发生冷凝粘结最终导致堵塞，阻碍反应进行。由于进气管道内还设有扰流结构，金属蒸气流经管道时在扰流结构的作用下增加流体湍流程度，减薄热边界层，显著提升传热系数，减少了换热器总成后续的换热压力，显著提高金属蒸气冷凝效率。
