Description
Technical field
The utility model relates to pressure vessel, relates in particular to shell and tube exchanger.
Background technology
At present, existing shell and tube exchanger generally adopts the single system structure, and it needs two tube sheets, twice tube bank expanded joint; If three shell and tube exchangers that system connects then need six tube sheets, six tube bank expanded joints, obviously material cost is higher, and heat exchanging fluid takes place and leaks in long processing time, and three systems' use bolts connections easily.
The utility model content
The purpose of the utility model is to provide a kind of three systems series connection shell and tube exchanger, when guaranteeing exchange capability of heat, reduces manufacturing cost, and can practice thrift the unit space.
For realizing the three systems series connection shell and tube exchanger of said purpose; Be characterized in; Comprise left shell, middle casing and right shell body, each housing disposes the input and output material assembly, and the right-hand member of left shell and the left end of middle casing are connected the two sides of left side sagging plate respectively; The right-hand member of middle casing and the left end of right shell body are connected the two sides of right side sagging plate respectively, thereby left shell, middle casing and right shell body serial connection are in aggregates.
Described three systems series connection shell and tube exchanger, its further characteristics are that heat-exchanging tube bundle becomes one-part form and passes the left and right side sagging plate.
Described three systems series connection shell and tube exchanger; Its further characteristics are; The left end of left shell connects the left outer tube plate; The right-hand member of right-hand member housing connects the right outer tube plate, and heat-exchanging tube bundle becomes one-part form and passes left and right outer tube plate and the left and right side sagging plate, and left outer tube plate and right outer tube plate are connected with bobbin carriage respectively.
Described three systems series connection shell and tube exchanger, its further characteristics are that the left and right side sagging plate welds with each housing respectively.
Described three systems series connection shell and tube exchanger, its further characteristics are that heat-exchanging tube bundle adopts middle expand tube connected mode to be connected respectively with the left and right side sagging plate.
Described three systems series connection shell and tube exchanger, its further characteristics are that channel flange is provided with anti-top fastening bolt hole.
Described three systems series connection shell and tube exchanger, its further characteristics are that this three systems heat exchangers in series is a condenser.
Described three systems series connection shell and tube exchanger, its further characteristics are that this three systems heat exchangers in series is a flooded evaporator.
Described three systems series connection shell and tube exchanger, its further characteristics are that this three systems heat exchangers in series is a downward film evaporator.
The utility model changes three sections original heat-exchanging tube bundles into the one-part form heat-exchanging tube bundle, passes four tube sheets respectively, and heat-exchanging tube bundle and outer tube plate can adopt conventional expanded joint or welding connecting mode, expand tube connected mode in the middle of heat-exchanging tube bundle and two sagging plates can adopt.The beneficial effect of the utility model is; When guaranteeing the heat exchanger exchange capability of heat, reduced by two tube sheets, twice tube bank expanded joint time, sagging plate and housing adopt and are welded to connect; Avoid heat exchanger tube side fluid to leak; Heat-exchanging tube bundle is an one-part form, makes things convenient for cleaning, the maintenance of heat exchanger, has reduced manufacturing cost.
Description of drawings
Fig. 1 is the utility model three system's heat exchangers in series structure charts
The specific embodiment
As shown in Figure 1; Three systems series connection shell and tube exchanger comprises left shell 1, middle casing 2 and right shell body 3; Each housing 1,2,3 disposes charging and discharging assembly 6,7, and the left end of left shell 1 connects left outer tube plate 9, and the left end of the right-hand member of left shell 1 and middle casing 2 is connected the two sides of left side sagging plate 11 respectively; The right-hand member of middle casing 2 and the left end of right-hand member housing 3 are connected the two side of right side sagging plate 12 respectively; The right-hand member of right-hand member housing 3 connects right outer tube plate 10, thereby left shell 1, middle casing 2 and right shell body 3 serial connections are in aggregates, and 8 one-tenth one-part forms of heat-exchanging tube bundle also pass left and right outer tube plate 9,10 and left and right side sagging plate 11,12.Heat-exchanging tube bundle 8 is an one-part form, this kind easy design the cleaning of heat exchanger, maintenance.
Left and right side sagging plate 11,12 welds with each housing 1,2,3 respectively, avoids heat exchanging fluid to reveal.
Heat-exchanging tube bundle 8 adopts middle expand tube connected mode to be connected respectively with left and right side sagging plate 11,12.
Channel flange is provided with anti-top fastening bolt hole, the dismounting of bobbin carriage when making things convenient for heat exchanger to clean.
Three systems series connection shell and tube exchanger can have multiple use, and for example for this three systems heat exchangers in series is a condenser, perhaps this three systems heat exchangers in series is a flooded evaporator, and perhaps this three systems heat exchangers in series is a downward film evaporator.
Though the utility model is described with reference to current specific embodiment; But those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model, under the situation that does not break away from the utility model spirit, also can make the variation or the replacement of various equivalences, and for example train is not defined as three systems among the embodiment of three systems series connection shell and tube exchanger; Can be for more than or equal to four systems; At this moment, described heat exchanger needs the quantity of corresponding increase heat-exchange system and sagging plate, uses more than or equal to three sagging plates to be integral body more than or equal to four heat-exchange system series connection.Therefore, as long as in the connotation scope of the utility model in the scope to the variation of the foregoing description, claims that modification all will drop on the application.
