Abstract

The invention discloses a rotary tube-plate type heat exchanger which comprises a support column, wherein a motor box, a water inlet box, a heat exchange box and a water outlet box are supported on the support column sequentially from left to right; a drive motor is arranged in the motor box; a rotating shaft bearing is fixed in the inner walls of the motor box and the water inlet box; a water pipe bearing is arranged at the center of the right side wall of the water inlet box; an incoming water pipe penetrates in the water pipe bearing and is fixed between a fixing ring and a switchover waterinlet box; the switchover water inlet box is positioned in the water inlet box; a heat exchange pipe is positioned at the central axis of a heat exchange chamber; a switchover water outlet box is positioned in the water outlet box; a hot water outlet is formed in the bottom of the water outlet box; a return water spiral plate is fixed between heat exchange pipes in the heat exchange box; an exchange water inlet is formed in the right bottom of the heat exchange box; cleaning plates are arranged on two sides of the bottom and top of the heat exchange box. According to the rotary tube-plate type heat exchanger disclosed by the invention, the effective travel and efficiency of heat exchange are improved by use of the rotating return water spiral plates.

Description

technical field [0001] The invention relates to a relatively large scope, in particular to a rotary tube-sheet heat exchanger. Background technique [0002] The fixed tube-sheet heat exchanger is mainly composed of shell, tube sheet, tube bundle, top cover and other components. In the circular shell, parallel tube bundles are installed, and the two ends of the tube bundle are fixed on the tube sheet by welding or expansion. Two pieces The tube sheet is directly welded to the outer tube, and the top cover with the inlet or outlet tube is connected to the flanges at both ends of the shell with bolts. It is characterized by a simple structure, no shell-side sealing connection, and the same shell inner diameter has the largest number of tubes. In the flow with baffles, the bypass is the smallest, and the tube pass can be divided into any number of tube passes. Because the two tube sheets are supported by the tubes, it has the thinnest tube sheet and the lowest cost in various sh...
