Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of condensing devices, and in particular to a compact mixing condenser with enhanced heat exchange. Background Art
[0002] As the power generation of power plants gradually increases, the size of their steam condensers also gradually increases. Therefore, there is an urgent need to improve the heat exchange capacity of steam condensers. Traditional steam condensers can be divided into shell and tube indirect condensers and hybrid condensers. Among them, the shell and tube indirect condenser adopts an indirect heat exchange method in which steam flows through the shell side and cooling water flows through the tube side. The total heat transfer coefficient is low and the volume is large. The hybrid condenser adopts a phase change heat transfer method in which steam and cooling water are directly contacted and condensed. The heat transfer coefficient is very high and can effectively reduce the volume of the condenser. In order to form a stable water film, the hybrid condenser currently used in power plants will be equipped with a water chamber in the middle position inside the condenser. Water is replenished inside the condenser through an external pump device. A nozzle is installed on the water chamber. The function of the nozzle is to form a water film with the sprayed water so that it can exchange heat with the steam efficiently. However, since the steam in the current hybrid condenser flows in a one-way manner from top to bottom, the contact time with the liquid film is relatively short. Moreover, after the steam enters the large space inside the condenser from the inlet, the flow rate will decrease, and the convective heat transfer coefficient will also decrease accordingly, thereby affecting the overall heat transfer coefficient. In order to ensure that the steam can be fully condensed, in addition to increasing the amount of liquid film, the height of the hybrid condenser needs to be increased to extend the contact heat exchange time between the steam and the liquid film. This results in the hybrid condenser being unable to be effectively reduced in height, which is not conducive to its application in certain scenarios with limited height space.

[0033] The following combination Figure 1-Figure 3 The enhanced heat exchange compact mixing condenser 1 provided by the present invention is described.
[0034] In order to solve the problems of low condensation efficiency and large size of the mixing condenser in traditional technology, an embodiment of the present invention provides an enhanced heat exchange compact mixing condenser 1, including a condenser shell 2, a water chamber 3, a first condensation structure 4 and a second condensation structure 5.
[0035] The condenser housing 2 has a mounting cavity 7 therein. A main inlet 8 and a main outlet 9 are provided on the condenser housing 2, which are in communication with the mounting cavity 7. Steam to be cooled enters through the main inlet 8, and condensed water flows out through the main outlet 9. A water chamber 3 is provided within the mounting cavity 7 and extends axially along the condenser housing 2. The water chamber 3 has a cooling water inlet and a cooling water outlet. The water chamber 3 is also provided with a plurality of condensation nozzles 10. Cooling water flows through the condensation nozzles 10 to form a cooling liquid film, and the steam is cooled by contact with the cooling liquid film.
[0036] The first condensation structure 4 is arranged near the main inlet 8. The first condensation structure 4 has a first steam inlet 11 and a first steam outlet 12. A reciprocating first steam flow channel 13 is formed between the first steam inlet 11 and the first steam outlet 12. The first steam inlet 11 is connected to the main inlet 8. The provision of the first steam flow channel 13 lengthens the flow path of the steam and increases the contact time between the steam and the liquid film, which is beneficial to improving the condensation efficiency of the steam. Correspondingly, a plurality of liquid film channels 14 are provided between the first steam inlet 11 and the first steam outlet 12, and each liquid film channel 14 is arranged corresponding to each condensation nozzle 10 in sequence. The liquid film sprayed from the nozzle will pass through the liquid film channel 14 and produce sufficient contact condensation with the steam in the first steam flow channel 13. The provision of the liquid film channel 14 and the first steam flow channel 13 does not affect the film formation quality of the liquid film, but can also increase the contact time between the steam and the liquid film, so that the steam and the liquid film present a nearly countercurrent heat exchange mode, which can greatly improve the steam condensation effect, thereby reducing the size of the condensation area in the height direction and thus reducing the size of the condenser.
[0037] The second condensation structure 5 is provided between the first condensation structure 4 and the main outlet 9. The second condensation structure 5 has a second steam inlet 19 and a second steam outlet 20. A reciprocating second steam flow channel 21 is formed between the second steam inlet 19 and the second steam outlet 20. The second steam inlet 19 is connected to the first steam outlet 12, and the second steam outlet 20 is connected to the main outlet 9. There are also multiple water sprinkling channels 22 provided between the second steam inlet 19 and the second steam outlet 20, which are provided through the second steam flow channel 21. One end of the water sprinkling channel 22 is connected to the first steam flow channel 13, and the other end of the water sprinkling channel 22 is connected to the main outlet 9. The condensed water generated in the first condensation structure 4 continues to condense the steam in the second steam flow channel 21 through the water sprinkling channel 22. The provision of the second steam flow channel 21 and the water sprinkling channel 22 can, on the one hand, increase the contact time between the steam and the water sprinkling, thereby improving the steam condensation effect, and on the other hand, can reduce the height dimension of the water sprinkling area, thereby reducing the size of the condenser.
[0038] See Figure 1 In the technical solution provided by the present invention, a plurality of condensation nozzles 10 are provided on both side walls of the water chamber 3 that are axially opposite to each other, and a plurality of the first condensation structures 4 and the second condensation structures 5 are provided on both sides of the water chamber 3. It should be noted that the condensation nozzles 10 can be set as multiple groups along the axial intervals of the condenser shell 2, and each group of condensation nozzles 10 includes a plurality of condensation nozzles 10 spaced apart along the height direction of the condenser shell 2, so that the space can be utilized to the maximum extent and the condensation efficiency can be improved. In addition, in this embodiment, the first condensation structures 4 are set as two, which are symmetrically arranged along the two sides of the water chamber 3, and of course they can also be asymmetrically arranged; the second condensation structures 5 are also set as two, which are arranged along the two sides of the water chamber 3. It should be noted that the second condensation structures 5 can be set as four, six or eight according to actual applications to meet the steam condensation needs under high working conditions. The present invention is not limited to this.
[0039] Specifically, see Figure 1-Figure 2 The first condensation structure 4 covers the entire liquid film area and includes a guide plate 17, a first water sprinkling plate 18, and a plurality of first baffles 15. One end of the guide plate 17 is connected to the side wall of the water chamber 3, and the other end extends toward the condenser shell 2. The first water sprinkling plate 18 is separated from the guide plate 17. One end of the first water sprinkling plate 18 is connected to the condenser shell 2, and the other end extends toward the side wall of the water chamber 3. The first baffles 15 extend along the height direction of the condenser shell 2. The first baffles 15 are staggered on the guide plate 17 or the first water sprinkling plate 18 in sequence. A steam flow channel is formed between two adjacent first baffles 15. All steam flow channels are connected end to end in sequence to form a reciprocating first steam flow channel 13. Please refer to Figure 2In this embodiment, steam enters from both sides of the condenser shell 2, flows toward the middle through the first steam inlet 11 along the flow space formed by the first baffle 15, and finally flows downward from the side wall of the water chamber 3 structure into the second condensation structure 5. It should be noted that in this embodiment, the first baffles 15 are arranged in parallel, and the steam flow channels formed are also arranged in parallel. Of course, the first baffles 15 can also be arranged to be inclined to each other, and the present invention is not limited to this. It should also be noted that more guide plates 17 structures can also be set in the space between the main inlet 8 and the water chamber 3 structure to better guide the steam to flow to both sides.
[0040] Furthermore, a plurality of groups of liquid film through holes 16 are correspondingly provided on the first baffle 15, and each group of liquid film through holes 16 includes a liquid film through hole 16 provided on each first baffle 15. A group of liquid film through holes 16 is provided corresponding to a condensation nozzle 10, and a sheet-like liquid film is sprayed out from each condensation nozzle 10, passing through the liquid film through holes 16 on each first baffle 15 successively, and finally forming a complete liquid film to condense and contact with the steam in the first steam flow channel 13.
[0041] Furthermore, the end of the guide plate 17 facing away from the water chamber 3 smoothly transitions to the nearest first baffle 15. The guide plate 17, the first baffle 15, and the condenser housing 2 together form a first steam inlet 11. The end of the first water spray plate 18 facing away from the water chamber 3 smoothly transitions to the nearest first baffle 15. The first water spray plate 18, the first baffle 15, and the sidewall of the water chamber 3 together form a first steam outlet 12. This arrangement ensures smooth steam flow through the aforementioned corners, thereby reducing adverse factors such as steam flow separation. Similarly, the end of the first baffle 15 is curved and smoothly transitions to the condenser housing 2, thereby ensuring smooth steam flow.
[0042] See Figure 1Specifically, the second condensation structure 5 includes a second water sprinkling plate 23 and a second baffle 24. The second water sprinkling plate 23 is separated from the first water sprinkling plate 18. One end of the second water sprinkling plate 23 is connected to the side wall of the water chamber 3, and the other end extends toward the condenser shell 2. Each second baffle 24 extends along the height of the condenser shell 2. The second baffles 24 are alternately arranged on the first water sprinkling plate 18 or the second water sprinkling plate 23. A steam flow channel is formed between two adjacent second baffles 24. All steam flow channels are connected end to end to form a reciprocating and circuitous second steam flow channel 21. Multiple water sprinkling holes 25 are correspondingly formed on the first water sprinkling plate 18 and the second water sprinkling plate 23. Two water sprinkling holes 25 correspondingly arranged along the height of the shell form a water sprinkling channel 22. It should be noted that the size of the water sprinkling holes 25 can be changed according to the situation and does not have to be exactly the same size. It can be a combination of water sprinkling holes 25 of multiple sizes. Condensed water and cooling water can flow downward through the water sprinkling holes 25 to form sprinkling water. The steam is further in contact with the sprinkling water when flowing through the second steam flow channel 21, thereby achieving further condensation of uncondensed steam and heat recovery of the sprinkling water. The second condensation structure 5 can increase the contact time between steam and sprinkling water, improve the steam condensation effect, thereby reducing the size of the sprinkling area in the height direction, and further reducing the size of the condenser.
[0043] Furthermore, the second water sprinkling plate 23, the second baffle plate 24 and the side wall of the water chamber 3 are enclosed to form a second steam inlet 19, and the second water sprinkling plate 23, the second baffle plate 24 and the condenser shell 2 are enclosed to form a second steam outlet 20. From the second steam inlet 19 to the second steam outlet 20, the distance between the first water sprinkling plate 18 and the second water sprinkling plate 23 is gradually reduced. Since the steam content is the highest when the steam just enters the second baffle plate 24 area, and the condensation amount is the largest after contacting the cooling water, more space is needed below it to store condensed water to prevent the condensed water from being too high and submerging the second steam flow channel 21.
[0044] Furthermore, from the first steam inlet 11 to the first steam outlet 12, the distance between two adjacent first baffles 15 is gradually reduced, and from the second steam inlet 19 to the second steam outlet 20, the distance between two adjacent second baffles 24 is gradually reduced. In this way, the steam can have approximately the same flow rate in each steam flow channel, ensuring an efficient convective heat transfer coefficient between steam and water.
[0045] See also Figure 1The end of the water chamber 3 near the main outlet 9 is provided with an air extraction zone 6. The air extraction zone 6 has an air extraction inlet 26 and an air extraction outlet 27. The air extraction inlet 26 is connected to the mounting cavity 7, and the air extraction outlet 27 is connected to the air extraction pump. The condensed water is finally collected into the water tank at the bottom of the condenser through the main outlet 9. There is still a gas space above. The uncondensed gas enters the air extraction zone 6 through the air extraction inlet 26 and is eventually pumped out by the external air extraction pump. The condensed water is then pumped away by an external circulating water pump and provided to users in need, ensuring that the water level in the water tank remains relatively stable.
[0046] The enhanced heat exchange compact mixing condenser 1 provided by the present invention has an intermittent first baffle 15 that does not affect the quality of liquid film formation, but can also increase the contact time between steam and liquid film, so that the steam and liquid film present a nearly countercurrent heat exchange mode, which can greatly improve the steam condensation effect, thereby reducing the height size of the condensation area; the second baffle 24 can increase the contact time between steam and water, improve the steam condensation effect, and thus reduce the height size of the water spraying area. The multi-layer water spraying plate structure can not only achieve further condensation of steam, but also reheat the cooling water and reduce the supercooling of the condensed water, thereby achieving efficient and reasonable use of cooling water, avoiding the problem of excessive power consumption of the circulating water pump caused by a large deviation between the actual cooling water demand and the theoretical demand.
[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
