[0030] In the first aspect of the present application, a condenser is provided, referring to the accompanying Figure 1 and 2The condenser comprises a steam inlet 100, a steam flow guide section 200, a condensing section 300, and a steam flow guide section 200 is provided with a steam inlet 100 at a contraction end, the condensing section 300 is arranged at one end of the steam flow guide section 200 away from the steam inlet 100, along the length direction (i.e. X direction) of the condenser, the condensing section 300 comprises at least two condensing modules 310, along the height direction (i.e. Z direction) of the condenser, each condensing module 310 comprises at least two condensing sub-modules 320, each condensing sub-module 320 comprises a plurality of condensing pipes 321, the condensing pipes 321 extend along the width direction (i.e. Y direction) of the condenser, along the direction from high to low of the condensing section 300, the diameters of the condensing pipes 321 of each condensing sub-module 320 in the condensing module 310 decrease in turn. Thus, the condensing pipes are arranged in parallel with the short side of the condenser, compared with the parallel arrangement with the long side, the length of the condensing pipes is shortened, the amount of thermal expansion deformation of the condensing pipes is reduced, the required support tube plate is reduced, the anti-flow-induced vibration performance is improved, the cross section of the tube bundle (i.e. condensing pipes) is large, the heat exchange capacity can be improved through the optimization of the arrangement of the tube bundle, the modular structure is adopted, and the steam flow and condensation heat exchange process can be fully optimized. By decreasing the diameters of the condensing pipes of each condensing sub-module 320 in the condensing module 310 in turn, the condensing pipes in each height condensing sub-module 320 can withstand the scouring of steam, adapt to the medium working conditions, and greatly improve the heat exchange surface density of the condenser.

[0031] The principle of the condenser proposed in the application capable of realizing the beneficial effects described above is described in detail as follows:

[0032] In the prior art, the condensing tubes of the condenser are distributed along the length direction of the condenser, resulting in that the condensing tubes are long, the steam entering the condenser is prone to cause pipe vibration due to steam impact, more support tube plates are needed, the range of thermal expansion deformation is large, the structure expansion compensation design requirement is high, the pipe bundle cross section is relatively small, which is not conducive to the optimal arrangement of the pipe bundle, and it is difficult to ensure the low resistance and uniform passage of the steam; especially for the condenser with a length-width ratio of more than 3 (the length of the condensing section 300 along the length direction is more than 3 times the length of the condensing section 300 along the width direction), the above problems are more prominent. In order to solve the above problems, the condensing section 300 is divided into at least two condensing modules 310 along the length direction (i.e. the X direction) of the condenser, each condensing module 310 is divided into at least two condensing sub-modules 320 along the height direction (i.e. the Z direction) of the condenser, and the condensing tubes extend along the width direction (i.e. the Y direction) of the condenser. Thus, first, the condensing tubes are arranged parallel to the short side of the condenser, which shortens the length of the condensing tubes compared with the parallel arrangement scheme of the long side, reduces the thermal expansion deformation of the condensing tubes, and under the same conditions, the requirement for structure expansion compensation design is relatively reduced, and the requirement for pipe support can be appropriately reduced. The length of the condensing tubes is relatively short, the required support tube plates are reduced, the spacers arranged between adjacent condensing sub-modules 320 can achieve the purpose of support, and the resistance to flow-induced vibration is improved. Second, the pipe bundle (i.e. the condensing tube) has a large cross section, and the modular arrangement can fully optimize the pipe bundle arrangement to ensure the low resistance and uniform passage of the steam, which is beneficial to improve the efficiency; and the large cross section of the pipe bundle increases the flow area of the circulating cooling water, and improves the heat exchange capacity of the condenser. Third, the modular structure can adjust the heat exchange capacity by adjusting the number of condensing modules 310 used to adapt to different working conditions (such as variable working condition adjustment, leakage pipe blocking, replacement and maintenance), which is extremely beneficial to actual use.

[0033] Meanwhile, in the prior art, the condensing pipe is mainly a conventional large-diameter heat exchange pipe, and the large-diameter condensing pipe is not conducive to improving the heat transfer area density of the condenser, and the single outer diameter of the pipe in the condensing pipe bundle is not conducive to the optimization of the condensation process heat exchange and flow. In order to solve the above problems, the diameter of the condensing pipe of each condensing sub-module 320 in the condensing module 310 is sequentially reduced, and the diameters of the condensing pipes in the same condensing sub-module 320 are equal. Therefore, the diameters of the condensing pipes in the condensing sub-modules 320 at different heights are different, and the diameters of the condensing pipes in the condensing sub-modules 320 in the first row are relatively large, which can directly withstand the scouring of steam, slow down the steam flow rate, and the heat exchange pipe has a large diameter, a large internal cold fluid (generally cooling water) volume, a large heat melting, and a good heat shock resistance. Since the condensing pipes in the first row of condensing sub-modules 320 have slowed down the steam flow rate, the flow rate of the steam flowing to the second row of condensing sub-modules 320 has been reduced, and the impact force has also been reduced. Therefore, the diameter of the condensing pipe in the second row of condensing sub-modules 320 can be reduced to a range that can withstand the impact of the steam after the flow rate is slowed down. Similarly, the diameter of the condensing pipe in the third row of condensing sub-modules 320 can be further reduced, and the same applies to the other rows, which will not be described here. Therefore, under the premise that the cross section of the condensing sub-module 320 is equal, the heat transfer surface density of the condenser is increased by reducing the diameter of the condensing pipe, the heat transfer effect of the condenser is improved, the heat transfer capacity of the condenser is enhanced, and the compactness of the condenser is improved. The reason for setting the diameters of the condensing pipes in the same condensing sub-module 320 to be equal is that the manufacturing difficulty and cost of the condensing sub-module 320 composed of equal-diameter condensing pipes are low.

[0034] Specifically, referring to the accompanying drawings Figure 1 and 2 One end of the steam guide section 200 is in a constricted shape, and the other end is in an expanded shape. The constricted end of the steam guide section 200 is connected to the steam inlet 100, and the expanded end of the steam guide section 200 is connected to the condensing section 300.

[0035] In the embodiments of the present application, referring to the accompanying drawings Figure 1The condenser further comprises at least two first module heads 330 and at least two second module heads 340, at least two first end plates 350 and at least two second end plates 360. The first module head 330 is detachably arranged at one end of the condensing module 310 along the width direction, and the second module head 340 is detachably arranged at the opposite end. The first module head 330 is provided with a water inlet pipe, and the cooling liquid in the water inlet pipe is distributed to the condensing pipes in the condensing sub-modules 320 through the first module head 330. The cooling liquid flows into the second module head 340 after flowing through the condensing pipes, and then flows into the water outlet pipe provided on the second module head 340 after being collected by the second module head 340, thereby realizing the flow of the cooling liquid. Specifically, the first module head 330 and the second module head 340 can be detachably fixed to the wall surface of the condensing section 300 by bolts. It should be noted that one condensing module 310 is correspondingly provided with one first module head 330 and one second module head 340.

[0036] In the embodiments of the present application, reference is made to the accompanying drawings Figure 1 The condenser further comprises at least four first end plates 350 and at least four second end plates 360, wherein the first end plate 350 is arranged at one end of the condensing sub-module 320 along the width direction, and the second end plate 360 is arranged at the opposite end. The first end plate 350 and the second end plate 360 serve to form the condensing pipes in the condensing sub-module 320 into a fixed shape, thereby playing a fixing role. Therefore, one condensing sub-module 320 is correspondingly provided with one first end plate 350 and one second end plate 360.

[0037] The principle of dividing the condensing section 300 into several condensing modules 310 along the length direction of the condenser is to ensure the uniformity of the fluid and to take into account the implementability of pipe arrangement. It can be understood that if the condensing modules 310 are too many, the required water inlet pipe and water outlet pipe will also increase accordingly, resulting in difficulty in pipe arrangement and poor implementability. According to some specific embodiments of the present application, the size of a single condensing module 310 along the length direction of the condenser is 0.4-0.6 m, thereby further ensuring the uniformity of the fluid and the implementability of pipe arrangement.

[0038] According to still some specific embodiments of the present application, along the direction from high to low of the condensing section 300, each condensing module 310 comprises a first condensing sub-module, a second condensing sub-module,..., and an Nth condensing sub-module, wherein N≥3, and further, the condensing tubes in the Nth condensing sub-module are capillary condensing tubes. In this way, compared with the Nth condensing sub-module, the diameters of the condensing tubes in the first and second condensing sub-modules are larger, which can better withstand the scouring of the steam, slow down the steam flow rate, and after the buffering of the first and second condensing sub-modules, the steam flow rate flowing into the Nth condensing sub-module has been reduced, and the impact force is also reduced, so the condensing tubes in the Nth condensing sub-module can be set as capillary condensing tubes, the heat exchange surface density of the capillary tube bundle module is extremely high, and the heat exchange effect is better, thereby improving the heat exchange effect of the condenser and enhancing the heat exchange capacity of the condenser.

[0039] As a specific example, along the direction from high to low of the condensing section 300, each condensing module 310 comprises a first condensing sub-module, a second condensing sub-module, a third condensing sub-module, and a fourth condensing sub-module, and further, the diameters of the condensing tubes in the first condensing sub-module are 16-32 mm, preferably 20-25 mm; the diameters of the condensing tubes in the second condensing sub-module are 10-15 mm; the diameters of the condensing tubes in the third condensing sub-module are 5-10 mm; and the diameters of the condensing tubes in the fourth condensing sub-module are 3-5 mm. In this way, compared with the third and fourth condensing sub-modules, the diameters of the condensing tubes in the first and second condensing sub-modules are larger, which can better withstand the scouring of the steam, slow down the steam flow rate, and after the buffering of the first and second condensing sub-modules, the steam flow rate flowing into the third and fourth condensing sub-modules has been reduced, and the impact force is also reduced, so the condensing tubes in the third and fourth condensing sub-modules can be set as capillary condensing tubes, the heat exchange surface density of the capillary tube bundle module is extremely high, and the heat exchange effect is better, thereby improving the heat exchange effect of the condenser and enhancing the heat exchange capacity of the condenser.

[0040] According to still some specific embodiments of the present application, adjacent condensing modules 310 are arranged by the first spacing pieces 370, and the plurality of condensing modules 310 are not communicated with each other, thereby the heat exchange capacity can be adjusted by adjusting the number of the condensing modules 310 to adapt to different working conditions (such as variable working condition adjustment, leakage pipe blocking, replacement and maintenance), which is extremely beneficial to actual use.

[0041] According to still some specific embodiments of the present application, adjacent condensing sub-modules 320 in the same condensing module 310 are arranged by the second spacing pieces 380, and the plurality of condensing sub-modules 320 in the same condensing module 310 are communicated with each other to ensure that the steam entering the same condensing module 310 is as evenly distributed as possible among the condensing sub-modules 320.

[0042] According to still further specific embodiments of the present application, at least one partition 210 is arranged on the steam flow guide section 200 along the length direction of the condenser, and the partition 210 is connected with the first partition member 370, so as to divide the steam flow guide section 200 into at least two parts corresponding to the condensing modules 310, that is, one first partition member 370 corresponds to one partition 210, and the number of the sub-steam flow guide sections divided by the partitions is equal to the number of the condensing modules 310 divided by the first partition member 370. The steam to be condensed enters the steam flow guide section 200 from the steam inlet 100, and flows to each sub-steam flow guide section under the action of each partition, and then flows into each corresponding condensing module 310. Each partition and each sub-steam flow guide section has a certain flow guide effect, which is used to distribute the steam at the inlet, so as to ensure that the amount of steam gas obtained by each module is close to the same.

[0043] According to still further specific embodiments of the present application, the cross section of the condensing sub-module 320 includes at least one of a square, an approximate square, a circle and an approximate circle, and the cross section is the section of the condensing sub-module 320 perpendicular to the bottom surface of the condenser. Thus, compared with the existing industrial practice, many experience formulas and design methods can be directly used.

[0044] The process of condensing the steam to be condensed in the condenser of the present application is as follows:

[0045] 1) The steam to be condensed enters the steam flow guide section 200 from the steam inlet 100, and flows to each sub-steam flow guide section under the action of each partition, and then flows into each corresponding condensing module 310.

[0046] 2) Then, the steam entering each condensing module 310 is sequentially condensed in the first condensing sub-module 320, the second condensing sub-module 320, …, and the Nth condensing sub-module 320, respectively, so as to be condensed into liquid and flow into the bottom of the condenser, and then be discharged from the condenser through the pipeline at the bottom.

[0047] In a second aspect of the present application, a condenser assembly is provided. According to embodiments of the present application, the condenser assembly has the condenser described in the above embodiments. Thus, the condenser assembly has all the advantages of the condenser, which will not be described here again.
