Abstract
The invention discloses a heat exchanger of a shell pass integral wrapped shell structure. A heat exchanger used at present is not provided with a corresponding heat exchanging pipe protection structure at a medium inlet, and media easily corrode a shell at the position where a wrapped shell is not arranged. The heat exchanger comprises a shell pass integral wrapped shell which comprises a half wrapped shell (1), the half wrapped shell is connected with a left wrapped shell (2), the half wrapped shell is connected with a right wrapped shell (4) through a baffle (3), the upper portion of the right wrapped shell is connected with a medium inlet connecting device (5), the lower portion of the right wrapped shell is connected with a medium outlet connecting device (6), the part, corresponding to the left wrapped shell, of the medium inlet connecting device is provided with a stainless steel impingement plate (8), a transverse partition board (9) and a baffle plate (10) are arranged inside the half wrapped shell. A cavity chamber is formed by the transverse partition board, a pipe plate (11), the half wrapped shell, the left wrapped shell and the right wrapped shell, and the transverse partition board is connected with the pipe plate. The heat exchanger is used for power station water heat exchangers.

background technology:
the water-to-water heat exchanger using at present only designs containment structure at place, shell-side medium inlet, and does not design corresponding heat exchange tube protective structure at place, medium inlet, is not having the position medium of involucrum easily to lose housing.
summary of the invention:
the heat exchanger that the object of this invention is to provide the whole containment structure of a kind of shell side.
object of the present invention realizes by following technical scheme:
the heat exchanger of the whole containment structure of a kind of shell side, its composition comprises: the whole involucrum of shell side, the whole involucrum of described shell side comprises half involucrum, half described involucrum is connected with left involucrum, half described involucrum is connected with right involucrum by baffle plate, the top connecting media entrance tube connector of described right involucrum, the bottom connecting media outlet connecting pipe of described right involucrum, described medium inlet tube connector, described media outlet tube connector is connected with connecting pipe device respectively, on described left involucrum corresponding to described medium inlet tube connector, stainless steel impingement baffle is installed, half described involucrum inside has diaphragm plate, deflection plate, described diaphragm plate and tube sheet, half described involucrum, described left involucrum forms chamber, described diaphragm plate is connected with heat exchanger.
the heat exchanger of the described whole containment structure of shell side, described medium inlet jockey is connected with medium inlet tube connector, and described media outlet jockey is connected with media outlet tube connector.
the heat exchanger of the described whole containment structure of shell side, described left involucrum adopts semicircular structure, and the top of described left involucrum is straight plate, and described straight plate stretches in described right involucrum.
the heat exchanger of the whole containment structure of described shell side, described right involucrum adopts semicircular structure, and described right involucrum top is anchored on described left involucrum, described right involucrum and described left involucrum welded closure.
beneficial effect:
1. shell-side medium of the present invention is taken over and is entered in right involucrum by tube connector from shell-side medium inlet, get to the corrosion resistant plate pasting on left involucrum, enter afterwards in chamber, through the inner deflection plate left and right baffling arranging of involucrum, carry out heat exchange with feedwater in heat exchanger tube, this baffling mode, heat exchange mode with the pure adverse current of pipe side feedwater formation, after the complete baffling in the heat exchanger tube region on equipment center line top, shell-side medium flows out from involucrum afterbody, after enter below in the whole involucrum of a group and continue baffling heat exchange, through tube connector, from media outlet, take over away afterwards.
2. the present invention adopts whole containment structure, and shell-side medium is completely enclosed within involucrum, has avoided the erosion to heater housing.
3. the project organization of internal baffle of the present invention, makes heater inner tube shell-side medium can realize the heat exchange mode of pure adverse current, can improve heat exchange efficiency, thereby reduce equipment volume and on-the-spot floor space.
4. medium inlet of the present invention and exit arrange connecting pipe structure and fluid erosion prevention corrosion resistant plate structure, can avoid the erosion of medium exchange heat pipe.
5. the present invention can be applied in the heater of fired power generating unit, can be applied in again nuclear power generating sets conventional island heat exchanger, the feedwater of preheating oxygen-eliminating device when unit starting, the deaerating effect of raising oxygen-eliminating device.
