[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Combine the following Figure 1-Figure 5 The quiet direct contact condenser of the present invention is described.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a quiet direct contact condenser 1, comprising: a shell 11, a water chamber 12 and a porous permeable structure 13. A heat exchange chamber 111 is constructed in the shell 11, and an inlet 112 and an outlet 113 communicating with the heat exchange chamber 111 are opened on the shell 11. The water chamber 12 is arranged in the heat exchange chamber 111, and the water chamber 12 is constructed with a water supply chamber 121 to accommodate cooling water, and a water supply hole 122 communicating with the water supply chamber 121 is provided on the water chamber 12. The porous permeable structure 13 is arranged outside the water chamber 12, and a plurality of capillary channels 131 communicating with the inlet 112 and the outlet 113 are constructed on the porous permeable structure 13. The porous permeable structure 13 is attached to the outer wall of the water chamber 12 so that the capillary channels 131 and the water supply holes 122 are communicated. The porous permeable structure 13 is used for the cooling water in the water supply chamber 121 to penetrate, and the cooling water forms a cooling liquid film on the inner wall of the capillary channel 131.

[0026] In this embodiment, a heat exchange chamber 111 is constructed in the shell 11, and an inlet 112 and an outlet 113 are respectively provided at both ends of the heat exchange chamber 111. A water chamber 12 and a porous permeable structure 13 are provided in the heat exchange chamber 111 as a heat exchange structure. The inlet 112 is used to pass steam to be condensed. The steam entering the heat exchange chamber 111 is condensed into condensed water after passing through the heat exchange structure and is discharged from the outlet 113.

[0027] Specifically, the porous permeable structure 13 is a structural member having a plurality of micropores formed therein, wherein a portion of the micropore structure extends in the direction from the inlet 112 to the outlet 113 to form a capillary channel 131 connecting the inlet 112 and the outlet 113, and a portion of the micropore structure is located between the capillary channels 131 to connect the capillary channels 131. It is understandable that a portion of the micropores can also extend to the outer wall of the porous permeable structure 13.

[0028] The water supply cavity 121 of the water chamber 12 stores cooling water for heat exchange. A water supply hole 122 is provided on the outer wall of the water chamber 12 and fits with the porous permeable structure 13, so that the cooling water can penetrate into the capillary channels 131 of the porous permeable structure 13 through the micro-pore structure on the outer wall of the porous permeable structure 13, and finally form a cooling liquid film on the inner wall of the capillary channel 131. The steam to be condensed exchanges heat with the cooling liquid film when passing through the capillary channel 131, and finally condenses into condensed water and is discharged from the outlet 113.

[0029] The quiet direct contact condenser 1 of the present invention is constructed with a heat exchange chamber 111 in a shell 11, and an inlet 112 and an outlet 113 are respectively provided at both ends of the heat exchange chamber 111, so that the steam to be condensed is introduced into the heat exchange chamber 111 from the inlet 112, and condensed into condensed water in the heat exchange chamber 111 and discharged from the outlet 113. At the same time, a water chamber 12 and a porous permeable structure 13 are provided in the heat exchange chamber 111, and the cooling water in the water chamber 12 penetrates into the capillary channel 131 in the porous permeable structure 13 through the water supply hole 122, so as to form a cooling liquid film on the capillary channel 131, so that the steam is cooled and condensed into condensed water after heat exchange with the cooling liquid film when passing through the capillary channel 131. From the above, it can be seen that the quiet direct contact condenser 1 of the present invention mainly forms a cooling liquid film by the penetration of cooling water in the porous permeable structure 13, so as to fully contact and exchange heat with the steam. No impact and mechanical vibration will be generated during operation, and it is quiet and noiseless, which effectively solves the defect of large operating vibration and noise in the direct contact condenser in the prior art.

[0030] It is understandable that the porous permeable structure 13 in the present application has a large specific surface area, which enables the steam to fully contact the cooling liquid film, and can reduce the volume of the heat exchange structure while ensuring the condensation effect. In the existing condenser that forms the cooling liquid film through the nozzle and baffle structure, the adjacent nozzles are arranged at intervals, resulting in the discrete distribution of the continuous liquid film generated by the nozzle jet, and the space utilization rate of the direct contact condensation heat exchange is not high. It can be seen that the quiet direct contact condenser 1 of the present application can be more compact in internal structure and occupy less space than the existing direct contact condenser.

[0031] In some embodiments, Figure 1 As shown, the water chamber 12 is arranged along the central axis of the heat exchange chamber 111, and the porous permeable structure 13 is arranged around the outside of the water chamber 12. The inner wall of the porous permeable structure 13 is in contact with the outer wall of the water chamber 12, and the outer wall of the porous permeable structure 13 is in contact with the inner wall of the heat exchange chamber 111.

[0032] In this embodiment, the water chamber 12 is arranged on the central axis of the heat exchange chamber 111, and the porous permeable structure 13 is annular as a whole and is arranged between the water chamber 12 and the inner wall of the heat exchange chamber 111, so that all steam entering the heat exchange chamber 111 can pass through the porous permeable structure 13, and after heat exchange and condensation in the capillary channel 131 in the porous permeable structure 13, it is discharged from the outlet 113. At the same time, since the water chamber 12 is located on the central axis of the heat exchange chamber 111, the distance between the outer wall of the water chamber 12 and the inner wall of the heat exchange chamber 111 in all directions can be basically consistent, so that the cooling water in the water chamber 12 can be uniformly infiltrated in all directions, so that the cooling water can be more fully and uniformly infiltrated into each pore structure of the porous permeable structure 13, so that the cooling liquid film can be evenly and fully spread on the inner wall of each capillary channel 131.

[0033] Furthermore, in some embodiments, Figure 1 and Figure 2 As shown, the porosity of the porous permeable structure 13 gradually increases from the inner wall to the outer wall ( Figure 2 The point density in is used to illustrate the porosity in the porous permeable structure 13). In this embodiment, the porous permeable structure 13 is annular in structure as a whole, and its porosity gradually increases from the inner wall to the outer wall, so that the permeability of the annular structure gradually increases from the inner wall to the outer wall, so that the cooling water can fully and evenly penetrate into each position of the entire annular structure, avoiding the concentration of cooling water near the inner wall, so that the cooling liquid film can be spread more evenly and fully on the inner wall of each capillary channel 131. At the same time, it can be understood that the osmotic pressure of the structure between the inner wall and the outer wall of the porous permeable structure 13 of this embodiment can drive the cooling liquid film to spread evenly to each capillary channel 131, that is, a sufficiently large cooling water driving pressure head is not required to produce a uniform liquid film, while reducing the head and power loss of the cooling water pump source, reducing the difficulty of variable operating condition regulation of the condensing equipment.

[0034] Specifically, in some embodiments, the porous permeable structure 13 includes one or more of an aluminum skeleton structure, a copper skeleton structure, and a titanium skeleton structure. In this embodiment, by setting the porous permeable structure 13 as a skeleton-shaped structure with good thermal conductivity such as aluminum, copper, and titanium, the skeleton-shaped structure can directly form fine micro-pores for cooling water to penetrate and form capillary channels 131. At the same time, since the skeleton itself is made of a metal material with good thermal conductivity, the heat of the steam flow can also be conducted through the skeleton structure, and the skeleton can also exchange heat with the cooling liquid film, so that the heat is evenly transferred to various positions of the cooling liquid film and the skeleton, so that the cooling liquid film and the skeleton can both exchange heat with the steam together, which is conducive to condensing the steam to form condensed water.

[0035] Specifically, in some embodiments, a hydrophilic coating is coated on the surface of the porous permeable structure 13. In this embodiment, by coating the hydrophilic coating on the surface of the porous permeable structure 13, cooling water can be uniformly attached to the surface of the hydrophilic coating to form a uniform cooling liquid film.

[0036] In some embodiments, Figure 1 , Figure 4 and Figure 5 As shown, a guide area 114 and a water collection area 115 are provided between the porous permeable structure 13 and the outlet 113. A plurality of guide plates 116 are provided in the guide area 114 at intervals. A first guide channel 117 is formed between adjacent guide plates 116. One end of the first guide channel 117 is connected to the capillary channel 131, and the other end is connected to the water collection area 115. The water collection area 115 is connected to the outlet 113.

[0037] In this embodiment, a guide area 114 and a water collection area 115 which are connected in sequence are arranged between the porous permeable structure 13 and the outlet 113, so that the condensed water formed by condensation in the porous permeable structure 13 flows through the guide area 114 and the water collection area 115 in sequence and then is discharged from the outlet 113, wherein a plurality of guide plates 116 are arranged in the guide area 114, and a first guide channel 117 for the condensed water to flow is formed between the guide plates 116. When the condensed water flows through the first guide channel 117, the condensed water flows along the guide plates 116 to prevent the condensed water droplets from directly dripping from the capillary channel 131 to the inner wall of the heat exchange chamber 111 or dripping to the condensed water liquid surface below to generate noise. It can be understood that by adjusting the air intake or discharge volume of the condenser, or adding water to the water collection area 115, the condensate level can be submerged in the water collection area 115 and reach the guide area 114, so that the condensate flows along the guide plate 116 and merges into the condensate surface, and will not directly drip on the condensate surface to generate liquid flow excitation noise.

[0038] In some embodiments, Figure 1 , Figure 4 and Figure 5 As shown, the quiet direct contact condenser 1 further includes a cooling water header tank 14, which is disposed between the water chamber 12 and the outlet 113, the inner cavity of the cooling water header tank 14 is connected to the water supply cavity 121, and the cooling water header tank 14 is provided with a cooling water inlet 141 for connecting the inner cavity of the cooling water header tank 14 and the external water supply pipeline. The guide area 114 is disposed around the outside of the cooling water header tank 14.

[0039] In this embodiment, the cooling water header tank 14 is disposed between the water chamber 12 and the outlet 113, and is used to store cooling water and supply cooling water to the water chamber 12. At the same time, the cooling water header tank 14 is also provided with a cooling water inlet 141, so as to replenish cooling water into the cooling water header tank 14 through an external pipeline. It can be understood that the cooling water header tank 14 is located in the middle of the heat exchange chamber 111, and the guide area 114 surrounds the outside of the cooling water header tank 14, so as to guide the condensed water to the collection area 115.

[0040] In a specific embodiment, Figures 1 to 5 As shown, the inlet 112 is located at the top of the shell 11, and the outlet 113 is located at the bottom of the shell 11. The water chamber 12 is arranged along the central axis of the heat exchange chamber 111, and the porous permeable structure 13 is arranged around the outside of the water chamber 12. The water supply holes 122 on the water chamber 12 are divided into multiple groups, and the multiple groups of water supply holes 122 are arranged at intervals along the vertical direction. Each group of water supply holes 122 has multiple water supply holes, and the multiple water supply holes 122 in the same group are arranged at intervals along the circumference of the water chamber 12. The cooling water collecting tank 14 is connected to the bottom of the water chamber 12, and the cross-sectional size of the cooling water collecting tank 14 along the horizontal direction is larger than the cross-sectional size of the water chamber 12 along the horizontal direction. The guide area 114 is arranged at the bottom of the porous permeable structure 13 and surrounds the cooling water collecting tank 14. The water collecting area 115 is located at the bottom of the guide area 114.

[0041] During condensation, the steam to be condensed passes into the heat exchange chamber 111 from the inlet 112, and then flows into the capillary channel 131 of the porous permeable structure 13 under the action of gravity, and condenses into condensed water after heat exchange with the cooling liquid film in the capillary channel 131, and passes through the guide area 114 and the water collection area 115 in turn, and is discharged from the outlet 113.

[0042] In some embodiments, Figure 4 and Figure 5 As shown, a plurality of guide vanes 116 are arranged at intervals along the circumference of the heat exchange cavity 111 , one end of the guide vane 116 abuts against the outer wall of the cooling water header 14 , and the other end abuts against the cavity wall of the heat exchange cavity 111 .

[0043] In this embodiment, a plurality of guide plates 116 are arranged at intervals along the circumference of the heat exchange chamber 111 to form a plurality of first guide channels 117 arranged along the circumference of the heat exchange chamber 111, thereby uniformly guiding the condensed water along the circumference of the heat exchange chamber 111 to the water collection area 115.

[0044] Specifically, in combination with the above-mentioned embodiments, under the flow of steam and the flow of condensed water in the vertical direction, the guide vane 116 can extend in the vertical direction. Further, the guide vane 116 can be in the shape of a corrugated plate, and the folds of the corrugations extend in the vertical direction to improve the longitudinal strength of the guide vane 116 and prevent the guide vane 116 from bending. Optionally, the guide vane 116 can be arranged at an angle so that the condensed water can slide along the guide vane 116 into the condensed water liquid surface below, avoiding the condensed water from dripping directly in the vertical direction to generate liquid flow excitation noise.

[0045] Optionally, in some embodiments, Figure 1 As shown, the quiet direct contact condenser 1 further includes a liquid level meter 15 , which is disposed on the shell 11 , and is used to detect the liquid level height of the guide area 114 .

[0046] In this embodiment, a liquid level gauge 15 is installed on the housing 11 to detect the liquid level in the diversion area 114. When the liquid level has a certain height in the diversion area 114, it can be ensured that the condensed water can directly flow into the condensed water surface along the first diversion channel 117, so as to avoid the condensed water dripping on the condensed water surface to generate liquid flow excitation noise; when the liquid level does not reach the diversion area 114, there is a certain distance between the condensed water surface and the outlet of the first diversion channel 117, and the condensed water will drip on the condensed water surface after leaving the first diversion channel 117, thereby generating noise. Therefore, when the liquid level does not reach the diversion area 114, the air intake or drainage of the condenser is adjusted, or water is added to the water collection area 115 so that the liquid level can reach the diversion area 114.

[0047] Optionally, in some embodiments, Figure 1 As shown, a plurality of guide plates 118 are disposed between the inlet 112 and the porous permeable structure 13 to form a plurality of second guide channels 119 communicating with the inlet 112 and the porous permeable structure 13 .

[0048] In this embodiment, a plurality of guide plates 118 are arranged between the inlet 112 and the porous permeable structure 13 and a plurality of second guide channels 119 are formed so that the steam introduced into the inlet 112 can be diverted and the steam is evenly introduced into the capillary channels 131 at various positions of the porous permeable structure 13, so that the steam and the cooling liquid film in the capillary channels 131 are in full contact with each other for heat exchange and condensation into condensed water.

[0049] 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 embodiments of the present invention.
