列管式換熱器

列管式換熱器是目前化工及酒精生產上應用廣的一種換熱器。
它主要由殼體、管板、換熱管、封頭、折流擋板等組成。所需材質，可分別采用普通碳鋼、紫銅、或不銹鋼制作。在進行換熱時，一種流體由封頭的連結管處進入，在管流動，從封頭另一端的出品管流出，這稱之管程;另一種流體由殼體的接管進入，從殼體上的另一拉管處流出，這稱為殼程。

SHELL AND TUBE HEAT EXCHANGER

The shell and tube heat exchanger is a kind of heat exchanger that is most widely applied for chemical and alcohol production.
It is mainly composed of the shell,tube sheet,heat exchanging tube,sealing head,baffle plate,etc.It can be made of ordinary carbon steel,red copper or stainless steel.During the heat exchange,a kind of fluid enters from the tube connection of the sealing head,flows in the tube and exits from the other tube connection of the sealing head,which is called tube pass.
Another kind of fluid enters from the tube connection of the shell and exit from the other tube connection of the shell,which is called shell pass.

螺旋板換熱器

本設備是一種高效換熱設備，適用氣-氣、氣-液、液-液，以及用于冷凝和液體蒸發傳熱。該產品具有傳熱效率高，污垢自清能力強，節能效果好，體積小、價格便宜，使用可靠等優點。廣泛用于制藥、溶劑、化工、松香、染料、食品等行業的熱能交換、廢料回收。

SPIRAL PLATE HEAT EXCANGER
