Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of this utility model protection.
The utility model embodiment provides a kind of shell-and-tube heat exchanger, as shown in Figure 2, this shell-and-tube heat exchanger comprises: the upper cover 1 being provided with thermal fluid inlet 101, be provided with the low head 2 of hot fluid outlet ports 201, be provided with the heat exchanger tube 5 of cold fluid inlet 3 and cold fluid outlet 4, and the upper perforated plate 6 be arranged in heat exchanger tube 5, heat exchanger tube 7 and floating tubesheet 8, wherein, heat exchanger tube 7 is for carrying hot fluid, this shell-and-tube heat exchanger also comprises isolation tube sheet 9, isolation tube sheet 9 is between cold fluid inlet 3 and cold fluid outlet 4, and be oppositely arranged with upper perforated plate 6, heat exchanger tube 5 is divided into two cavitys by isolation tube sheet 9, and two cavitys are communicated with.
Particularly, above-mentioned two cavitys can by the gap area between isolation tube sheet 9 and the inwall of heat exchanger tube 5, and also can offer through hole on isolation tube sheet 9, two cavitys are communicated with by this through hole.
The shell-and-tube heat exchanger provided due to the utility model embodiment comprises isolation tube sheet 9, isolation tube sheet 9 is between cold fluid inlet 3 and cold fluid outlet 4, and be oppositely arranged with upper perforated plate 6, heat exchanger tube 5 is divided into two cavitys by isolation tube sheet 9, and two cavitys are communicated with, therefore, isolation tube sheet 9 can stop that the cold fluid flowed into from cold fluid inlet 3 directly flows to cold fluid outlet 4, compared with prior art, there is more cold fluid can contact with upper perforated plate 6, thus can effectively prevent upper perforated plate 6 temperature too high, maintain the normal work of shell-and-tube heat exchanger.
It should be noted that, cold fluid inlet 3 should be tried one's best and to be arranged near upper perforated plate 6, and isolation tube sheet 9 should be tried one's best, close cold fluid inlet 3 is arranged, thus make the flow distance in the cavity of cold fluid between upper perforated plate 6 and isolation tube sheet 9 shorter, and then the exchange heat that the hot fluid in the cold fluid decreased in this cavity and heat exchanger tube 7 carries out, make the cooling fluid temperature that contacts with upper perforated plate 6 lower, thus upper perforated plate 6 temperature can be prevented further too high.
In addition, as shown in Figure 3, upper perforated plate 6 is provided with the first thermal insulation layer 10 towards the one side of thermal fluid inlet 101, thus can reduce the heat that the hot fluid in upper cover 1 transmits to upper perforated plate 6, and then can prevent the temperature of upper perforated plate 6 from raising.Preferably, the material of the first thermal insulation layer 10 is castable.Compared with other heat-barrier materials, castable can at high temperature keep good intensity, thus when the temperature of the hot fluid flowed into from thermal fluid inlet 101 is higher, can prevent the first thermal insulation layer 10 from splitting because of high temperature, thus the heat that the hot fluid in upper cover 1 transmits to upper perforated plate 6 can be reduced, and then can prevent the temperature of upper perforated plate 6 from raising.
Further, present inventor finds, in the actual use procedure of shell-and-tube heat exchanger, the material of the first thermal insulation layer 10 may come off from upper perforated plate 6, and the material after coming off easily enters in heat exchanger tube 7, causes heat exchanger tube 7 to block.For avoiding the appearance of this problem, outstanding first thermal insulation layer 10 certain length of import of heat exchanger tube 7.In addition, the material passing the part that upper perforated plate 6 stretches in upper cover 1 in heat exchanger tube 7 is preferably the good pottery of heat-proof quality, thus the heat that the hot fluid in upper cover 1 transmitted to upper perforated plate 6 by heat exchanger tube 7 can be reduced, prevent the temperature of upper perforated plate 6 too high further.
In addition, as shown in Figure 4, the outer peripheral face of isolation tube sheet 9 is arranged with sealing ring 11, isolation tube sheet 9 is connected with the inner wall sealing of heat exchanger tube 5 by sealing ring 11, thus the cold fluid flowed into from cold fluid inlet 3 can be prevented to be flowed directly to cold fluid outlet 4 by the gap between isolation tube sheet 9 and the inwall of heat exchanger tube 5, the temperature of upper perforated plate 6 can be prevented further too high.Now, in order to make two cavitys in heat exchanger tube 5 be communicated with, isolation tube sheet 9 is also provided with the through hole of connection two cavitys.
Further, in order to prevent the heat exchange efficiency of shell-and-tube heat exchanger from declining, the inwall of heat exchanger tube 5 is provided with the second thermal insulation layer.But in the practical work process of shell-and-tube heat exchanger, stream has hot fluid in heat exchanger tube 7, make heat exchanger tube 7 thermal expansion can occur, thus drive isolation tube sheet 9 to move.In the process of isolation tube sheet 9 movement, sealing ring 11 meeting and the second thermal insulation layer generation relative sliding or extruding, cause the second thermal insulation layer to be scratched by sealing ring 11.For avoiding the appearance of this problem, sealing ring 11 in the utility model embodiment is preferably elastic seal ring, thus when sealing ring 11 and the second thermal insulation layer generation relative sliding or when extruding, elastic deformation can be there is to play cushioning effect in sealing ring 11, thus the second thermal insulation layer can be avoided to be scratched by sealing ring 11, prevent the heat exchange efficiency of shell-and-tube heat exchanger from declining.
In addition, as shown in Figure 5, shell-and-tube heat exchanger also comprises the guide shell 12 be fixed on isolation tube sheet 9, and the two ends of guide shell 12 lay respectively in two cavitys, and the distance exporting to floating tubesheet 8 of guide shell 12 is less than the distance of cold fluid outlet 4 to floating tubesheet 8.Therefore, the cold fluid flowed out from the outlet of guide shell 12 can flow to cold fluid outlet 4 along from floating tubesheet 8 to the direction of isolation tube sheet 9.Flow direction due to the hot fluid in heat exchanger tube 7 is the direction of self-isolation tube sheet 9 to floating tubesheet 8, contrary with the flow direction of cold fluid, thus make to form countercurrent flow between hot fluid and cold fluid, effectively improve the heat exchange efficiency between hot fluid and cold fluid, make the heat exchange efficiency of shell-and-tube heat exchanger higher.Exemplarily, guide shell 12 through isolating for being communicated with the through hole of two cavitys on tube sheet 9, and can be fixed on isolation tube sheet 9 by the mode of welding.
It should be noted that, from the above, the cold fluid flowed out from the outlet of guide shell 12 can flow to cold fluid outlet 4 along from floating tubesheet 8 to the direction of isolation tube sheet 9, now, in order to make cold fluid to flow to the flow distance before cold fluid outlet 4 longer, thus make to carry out exchange heat fully between cold fluid and hot fluid, need to make cold fluid outlet 4 as far as possible near isolation tube sheet 9.
But in the practical work process of shell-and-tube heat exchanger, stream has hot fluid in heat exchanger tube 7, make heat exchanger tube 7 thermal expansion can occur, thus drive isolation tube sheet 9 to move to floating tubesheet 8 direction from upper perforated plate 6.When the displacement of isolation tube sheet 9 is longer, and isolation tube sheet 9 and cold fluid outlet 4 between distance shorter time, cold fluid inlet 3 and cold fluid outlet 4 can all be positioned at the same side isolating tube sheet 9, cause the cold fluid flowed into from cold fluid inlet 3 directly to be flowed out by cold fluid outlet 4, make can not carry out exchange heat between cold fluid and hot fluid.For avoiding the appearance of this problem, need to arrange certain distance between cold fluid outlet 4 and isolation tube sheet 9, this distance needs the displacement being greater than isolation tube sheet 9.
In addition, as shown in Figure 6, at least one first outer deflection plate 13 of being parallel to each other and at least one deflection plate 14 in first is also provided with between upper perforated plate 6 and isolation tube sheet 9, in first outer deflection plate 13 and first, deflection plate 14 is ring baffle plate, and the first outer deflection plate 13 is oppositely arranged with isolation tube sheet 9, in the first outer deflection plate 13 and first, deflection plate 14 alternate intervals arranges.Therefore, the cold fluid flowed into from cold fluid inlet 3 can in the first deflection plate 13 and first deflection plate 14 stop under carry out baffling, prevent the cold fluid flowed into from cold fluid inlet 3 from flowing directly into the entrance of guide shell 12, contribute to more cold fluid to contact with upper perforated plate 6, thus upper perforated plate 6 temperature can be prevented further too high.
Exemplarily, as shown in Figure 6, the first outer deflection plate 13 is fixed on heat exchanger tube 7 by the mode of expanded joint, and in first, deflection plate 14 is fixed on guide shell 12 by the mode of expanded joint.Wherein, the internal diameter of the first outer deflection plate 13 is greater than the external diameter of guide shell 12, make the passage existed between the first outer deflection plate 13 and guide shell 12 for making cold fluid pass through, in first, the external diameter of deflection plate 14 is less than the internal diameter of heat exchanger tube 5, makes the passage existed between the inwall of deflection plate 14 and heat exchanger tube 5 in first for making cold fluid pass through.
Further, in order to make the baffling effect of the cold fluid between upper perforated plate 6 and isolation tube sheet 9 better, preferably, the internal diameter of the first outer deflection plate 13 is less than the external diameter of deflection plate 14 in first, thus after passage between the inwall making cold fluid flow through deflection plate 14 and heat exchanger tube 5 in first, cold fluid can be stopped by the first outer deflection plate 13, thus changes the flow direction of cold fluid.Similarly, after cold fluid flows through the passage between the first outer deflection plate 13 and guide shell 12, cold fluid can be stopped by deflection plate 14 in first, thus changes the flow direction of cold fluid.

Exemplarily, as shown in Figure 7, the second outer deflection plate 15 is fixed on heat exchanger tube 7 by the mode of expanded joint, and in second, deflection plate 16 is fixed on guide shell 12 by the mode of expanded joint.Wherein, the internal diameter of the second outer deflection plate 15 is greater than the external diameter of guide shell 12, make the passage existed between the second outer deflection plate 15 and guide shell 12 for making cold fluid pass through, in second, the external diameter of deflection plate 16 is less than the internal diameter of heat exchanger tube 5, makes the passage existed between the inwall of deflection plate 16 and heat exchanger tube 5 in second for making cold fluid pass through.
Further, comparatively even in order to make the cold fluid between isolation tube sheet 9 and floating tubesheet 8 distribute, preferably, the internal diameter of the second outer deflection plate 15 is less than the external diameter of deflection plate 16 in second, thus after passage between the inwall making cold fluid flow through deflection plate 16 and heat exchanger tube 5 in second, cold fluid can be stopped by the second outer deflection plate 15, thus changes the flow direction of cold fluid.Similarly, after cold fluid flows through the passage between the second outer deflection plate 15 and guide shell 12, cold fluid can be stopped by deflection plate 16 in second, thus changes the flow direction of cold fluid.
Further, in order to make the cold fluid between isolation tube sheet 9 and floating tubesheet 8, there is comparatively uniform flow velocity and carry out heat exchange equably to make the hot fluid in itself and heat exchanger tube 7, preferably, the width of passage in second between deflection plate 16 and the inwall of heat exchanger tube 5 is identical with the width of the passage between the second outer deflection plate 15 and guide shell 12.
Similarly, the outer peripheral face of the second outer deflection plate 15 also can be arranged with sealing ring 11, second outer deflection plate 15 is connected with the inner wall sealing of heat exchanger tube 5 by sealing ring 11, thus can prevent cold fluid from passing through from the gap between the second deflection plate 15 and the inwall of heat exchanger tube 5, and then improve the baffling effect of cold fluid.Further, when being provided with the second thermal insulation layer on the inwall of heat exchanger tube 5, the movement of the second outer deflection plate 15 also may scratch the second thermal insulation layer.For avoiding the appearance of this problem, sealing ring 11 in the utility model embodiment is preferably elastic seal ring, thus when sealing ring 11 and the second thermal insulation layer generation relative sliding or when extruding, elastic deformation can be there is to play cushioning effect in sealing ring 11, thus avoid the second thermal insulation layer to be scratched by sealing ring 11, prevent the heat exchange efficiency of shell-and-tube heat exchanger from declining.
