Abstract

본 발명은 콘트롤 슬리브가 내설된 폐열 열교환기에 관한 것으로 열교환기의 수명은 저온부식과 고온부식에 의하여 좌우되는 바, 종래 저온 부식은 열교환기의 튜우브에 공기유입구측에서 폐가스의 접촉이 적으면서 튜우브에 유입되는 공기가 와류현상을 일으키어 튜우브가 저온으로 되면서 저온 부식을 일으키는 문제점이 있었다.The present invention relates to a waste heat exchanger in which a control sleeve is built in. The lifespan of a heat exchanger is dependent on low temperature corrosion and high temperature corrosion. The air flowing into the web causes the vortex phenomenon and the tube becomes low temperature, causing a low temperature corrosion.

본 발명은 종래의 이러한 문제점을 시정하기 위하여 열교환기의 튜우브(1)의 공기유입구(2)와 작은 간극을 두고 형성하여, 공기실에서 튜우브로 공기가 유입되기 직전에 콘트롤 슬리브 내에서 유체의 안정화를 이루어 층류상태로 튜우브로 흐르게 하여서 튜우브의 저온방지로 저온부식을 예방할 수 있게 한 것이다.The present invention is formed with a small gap with the air inlet (2) of the tub (1) of the heat exchanger in order to correct this problem of the prior art, so that the fluid in the control sleeve immediately before the air flows into the tub from the air chamber Stabilization is made to flow to the tube in the laminar flow state to prevent cold corrosion by preventing the tube low temperature.
