Abstract
The utility model relates to a vertical type two-stage lamella heat exchanger, which comprises two lamella heat exchange devices which are arranged vertically, and a connecting pipe box with an expansion joint is arranged between the two lamella heat exchange devices. The lower end of the two-stage lamella heat exchanger is provided with an inlet pipe box, the upper end of the two-stage lamella heat exchanger is provided with an outlet pipe box, a housing of each lamella heat exchange device is respectively provided with a shell pass inlet, a shell pass outlet and a support for supporting the heat exchanger. The vertical type two-stage lamella heat exchanger disclosed by the utility model is high in heat transfer efficiency, small in occupied area, and low in metal consumption, and expansion difference caused by thermal stress of the two lamella heat exchange devices can be absorbed.
Description
Technical field
the utility model belongs to technical field of heat exchangers, relates to a kind of vertical two-stage plate shell heat exchanger.
Background technology
heat exchanger is oil, chemical industry, electric power, food and many other industrial common apparatus, is also heat energy recycle key equipment.Generally by heat exchanger peripheral disposition for delivery of the pipeline that needs heat exchange cold fluid and hot fluid, like this can loss partial heat energy in fluid is carried, owing to needing to arrange the equipment such as valve instrument of controlling use on pipeline, also cause the investment of whole equipment greatly to improve simultaneously.
for overcoming above-mentioned drawback, adopt two-stage heat exchanger to save heat energy and equipment investment more.Existing two-stage heat exchanger is shell-and-tube the two poles of the earth heat exchangers, its heat transfer efficiency is low, floor space is large, metal consumption and equipment investment high.
Utility model content
the utility model object is to provide that a kind of heat transfer efficiency is high, metal consumption is low, can absorb the vertical two-plate shell heat exchanger of the differential expansion that two shell-and-plate heat-exchanger rigs cause by thermal stress.
concrete technical scheme is as follows: a kind of vertical two-stage plate shell heat exchanger, comprise two shell-and-plate heat-exchanger rigs, and two shell-and-plate heat-exchanger rigs are placed up and down, adopt the connection bobbin carriage with expansion joint to be connected between two shell-and-plate heat-exchanger rigs.
described shell-and-plate heat-exchanger rig adopts veneer journey, single shell side structure.
the utility model adopts two-stage plate shell-type heat-exchanger rig, compare with two-stage shell-and-tube heat exchanger, its heat transfer coefficient increases greatly, because shell-and-plate heat-exchanger rig adopts corrugated plate dst heat transfer element, board-like heat transfer element do not manage inner membrance resistance enlarge-effect and sealing factor low, overall heat-transfer coefficient can be increased to 2 ~ 3 times of shell-and-tube heat exchanger, and floor space can reduce half.This device can be realized a kind of cold fluid and two kinds of hot fluids and carry out heat exchange or two kinds of cold fluids and a kind of hot fluid and carry out heat exchange, thereby adjustable wherein two kinds of fluid flows are realized the control to one other fluid final temperature, can make plate journey fluid heat transfer
final temperature is easy to control.The connection bobbin carriage that is used for connecting two lamella heat exchangers, with expansion joint, can absorb two differential expansions between lamella heat exchanger.
meanwhile, the utlity model has the advantages such as corrosion resistance and good, weight of equipment is low, cost is low.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model;
fig. 2 is top view of the present utility model.
drawing reference numeral: plate journey import 1; Import bobbin carriage 2; Leakage fluid dram 3; Plate bundle 4; Housing 5; Deflection plate or gripper shoe 6; Bearing 7; Shell side import 8; Manhole 9; Tube sheet 10; Outlet bobbin carriage 11; Plate journey outlet 12; Exhaust outlet 13; Shell side outlet 14; Expansion joint 15; Connect bobbin carriage 16.
The specific embodiment
below in conjunction with accompanying drawing, the utility model and beneficial effect thereof are described further.
as shown in Figure 1 and Figure 2, a kind of vertical two-plate shell heat exchanger, comprise two shell-and-plate heat-exchanger rigs 5 i.e. the first step shell heat-exchanger rig and the second step shell heat-exchanger rig, between the first step shell heat-exchanger rig and the second step shell heat-exchanger rig, adopt the bobbin carriage 16 that is connected with expansion joint 15 to be connected, two-stage plate shell heat exchanger lower end arranges import bobbin carriage 2, upper end arranges outlet bobbin carriage 11, and each lamella heat exchanger device 5 housing arranges respectively shell side import 8 and shell side outlet 14; Each lamella heat exchanger device 5 housing arranges respectively support carriers 7, for supporting heat exchanger; Each lamella heat exchanger device 5 shell end is equipped with tube sheet 10, and 10 of single-deck shell-type heat-exchanger rig 5 tube sheets are provided with corrugated board cluster 4; Described enclosure interior arranges polylith deflection plate or gripper shoe 6 for supporting corrugated board cluster 4, and to shell-side fluid baffling; Each housing can arrange used for expansion joint in absorbing the differential expansion of each housing 5 with plate bundle 4; Each housing 5 upper end arranges exhaust outlet 13, and lower end arranges leakage fluid dram 3.
plate journey fluid flows into first order shell-and-plate heat-exchanger rig by the plate journey import 1 of two-plate shell heat exchanger lower end import bobbin carriage 2, in first order shell-and-plate heat-exchanger rig with shell-side fluid heat exchange, after heat exchange, plate journey fluid is flowed out and is entered second level shell-and-plate heat-exchanger rig by the connection bobbin carriage 16 with expansion joint 15 by first order shell-and-plate heat-exchanger rig, and plate journey fluid is flowed out by the plate journey outlet 12 of upper end outlet bobbin carriage 11 in the shell-and-plate heat-exchanger rig of the second level with after shell-side fluid heat exchange.Shell-side fluid is flowed into by the shell side import 8 of two shell-and-plate heat-exchanger rigs respectively, housing 5 in by deflection plate 6 bafflings and with plate journey media for heat exchange, after heat exchange, fluid is by shell side outlet 14 outflows.
