Description
Technical field
The utility model relates to the energy exchange apparatus field of fluid, particularly relates to a kind of shell-and-tube heat exchanger with annular pass partition of two tube sides.
Background technology
For shell-and-tube heat exchanger design, except meeting technic index, requirement of mechanical strength, a prior content is exactly how reasonably to improve heat exchanger heat exchange efficiency more economically.In order to improve heat exchange efficiency, general technique is by way of being:
One, the time of contact of two kinds of heat exchange mediums is extended;
Two, the contact area of two kinds of heat exchange mediums is increased.
We know in technological design is prolongation and the time of contact of strengthening between medium and area, probably can take following several method:
One is increase shell side quantity, and be namely muitishell version design of heat exchanger structure, this is a kind of effective method, but manufacture difficulty is comparatively large, generally seldom adopts;
Two is increase tube side quantity, is namely multitube distance version design of heat exchanger structure, and this be the not only simple but also method commonly used; Two formula heat exchangers of generally flat pass partition are the most conventional, the current practice: two formula heat exchangers (as shown in Figure 1) of flat pass partition, its pass partition connected in end socket 1 is a flat board 2, connection end socket 1 is divided into left and right or upper and lower two parts, but when the medium temperature difference that cold fluid is imported and exported is larger, connect end socket 1 two-part thermal stress difference also larger.For ensureing the performance that is tightly connected of channel flange, design is often taked the measures such as the channel flange increasing tube sheet and adopt different-thickness, rigidity between end socket and bobbin carriage is connected to increase it, to improve stability and the sealing of the connection of integral device, and then add weight of equipment and manufacturing cost.
Utility model content
For above-mentioned Problems existing, it is lower that the utility model object is to provide a kind of manufacturing cost, ensures the shell-and-tube heat exchanger with annular pass partition of the stability that channel flange connects and sealing.
In order to achieve the above object, the technical solution adopted in the utility model is as follows: a kind of shell-and-tube heat exchanger with annular pass partition, described shell-and-tube heat exchanger comprises the bobbin carriage at middle part and the connection end socket at two ends, be connected by channel flange between described connection end socket and bobbin carriage, the both sides of described bobbin carriage are respectively equipped with thermal fluid inlet and hot fluid outlet ports, the connection end socket at described bobbin carriage two ends is connected by four groups of heat-exchange tubes, described connection end socket comprises top pressure closure and fluid transport end socket, the inside of described fluid transport end socket is provided with the pass partition of annular, fluid transport end socket is separated into the cylindrical zone of annular peripheral zone and inner side by described pass partition, respectively be provided with two groups of heat-exchange tubes in described annulus and cylindrical zone to be connected on top pressure closure.
Improve as one of the present utility model, the side of described fluid transport end socket is provided with cold fluid inlet, and the top of described fluid transport end socket is provided with cold fluid outlet; Because fluid transport end socket is separated into two independently annulus and cylindrical zone by the pass partition of annular, equipment, by being respectively equipped with cold fluid in/out mouth in two independently region, facilitates the fluid of two kinds of different temperatures to carry out exchange heat.
Improve as one of the present utility model, in described cold fluid inlet and cold fluid outlet, the transmission direction of cold fluid is reversible; Because this equipment only needs the stability of the channel flange operating temperature ensured on the position of the Contact connecting end socket and bobbin carriage, be no matter input heat exchange medium or heat outputting exchange media is uniform affects its operating temperature by cold fluid inlet, improve the range of application of device.
Improve as one of the present utility model, described fluid transport end socket is connected with adopting multiple identical channel flange between bobbin carriage; Because the channel flange between fluid transport end socket and bobbin carriage is all carry out work under the operating temperature of annulus, therefore adopt same channel flange can complete its work requirements, save the production cost of equipment.
Improve as one of the present utility model, the list group heat-exchange tube of four groups of described heat-exchange tubes in bobbin carriage linearly or curved arrangement; Owing to being respectively connected with two groups of heat-exchange tubes in annulus He in cylindrical zone, and the diameter of annulus is greater than cylindrical zone, therefore by the arrangement mode of different heat-exchange tubes, improves the heat exchanger effectiveness of device.
The utility model has the advantage of: because connection end socket is overall structure, but due to the limitation of flat pass partition common on the market, result in the difference connecting end socket two ends operating temperature, and then it is different to result in the operating temperature connecting end socket two end flanges, the utility model is by improving the limitation of flat pass partition, ensure that the stability and homogeneity that connect working stability outside end socket, and then ensure that channel flange operating temperature is even, its thermal expansion is consistent, when designing, channel flange selects grade more much lower than plate, only a lot of fund just saved by material one, the result of use of single unit system is better simultaneously, and sealing is reliable.
