Abstract

The invention discloses a high-speed S module multi-return-stroke heat exchanger. One end of a shell is connected with a first seal head through bolts, and the other end of the shell is connected witha second seal head through bolts; the first seal head is provided with a heat source inlet flange, a heat source outlet flange and a tube pass pressure meter connector; the second seal head is provided with a tube pass blow-down valve connector; the shell is provided with a temperature meter connector, a safety valve connector, a shell pass blow-down valve connector and a shell pass pressure meter connector; a first tube plate is installed between the shell and the first seal head, and a second tube plate is installed between the shell and the second seal head; one ends of heat exchange tubesare fixed to the first tube plate, and the other ends of the heat exchange tubes are fixed to the second tube plate; the heat source inlet flange, the heat source outlet flange, the first seal head,the heat exchange tubes and the second seal head form a tube pass, and a heat source flows in the tube pass; and a cold source outlet flange is welded to the position, close to the upper end of the first seal head, of the shell, a cold source inlet flange is welded to the position, close to the lower end of the second seal head, of the shell, and the cold source inlet flange, the shell and the cold source outlet flange form a shell pass.

Description

technical field [0001] The invention belongs to the technical field of heat exchange equipment, and in particular relates to a heat exchanger. Background technique [0002] Existing bellows heat exchangers and tube-and-tube heat exchangers are all forced turbulent flow heat exchangers, which form the tube side where the cold source is located by fixing multiple straight-through heat exchange tubes between two tube sheets. The shell where the heat source is located, the heat source is inside the shell, the heat dissipation loss is large, the heat exchange efficiency is low, and the occupied area is large. When used in condensers or heating network heaters, the steam will naturally condense through heat release in the shell and convert into condensed water. The condensed water has a high temperature and low pressure. It must be equipped with a steam trap and a condensed water chamber to work normally. And it is not easy to recycle, it needs a special condensate pump and conde...
