Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of sea water desalination, and particularly relates to an efficient sea water desalination equipment. BACKGROUND

[0002] As a crucial way to obtain fresh water resources, sea water desalination has irreplaceable significance for ensuring the drinking water supply of coastal residents, meeting the industrial boiler water replenishment demand and other stable water supply demand. With the global water resources becoming increasingly scarce, the importance of sea water desalination technology is increasingly prominent. It not only can help solve the problem of water resource shortage, but also can improve water quality, so as to ensure the safety and sustainable utilization of water resources.

[0003] At present, sea water desalination equipment mainly adopts two desalination technologies of distillation method and reverse osmosis method. The distillation method is a process of heating sea water to evaporate, and then condensing water vapor into fresh water, which is mainly used for large-scale sea water desalination treatment and places with rich heat energy. However, the distillation method needs to consume a large amount of heat energy to heat sea water, so the energy consumption is high. At the same time, the distillation method needs large equipment to support the processes of heating, evaporation and condensation, which increases the complexity and maintenance cost of the equipment. The reverse osmosis method is to pressurize sea water by a high-pressure pump, so that the sea water passes through the reverse osmosis membrane. Due to the selective permeability of the membrane, impurities such as salt are intercepted on one side of the membrane, and fresh water enters the other side through the membrane. However, the salt and impurities in the sea water can easily pollute the reverse osmosis membrane, causing the performance of the membrane to decline. Secondly, the replacement of the membrane needs professional technology and equipment, and the cost is high. The sea water needs to be pretreated before entering the reverse osmosis system to remove suspended solids, colloids, organic matter and other impurities, so as to prevent the pollution and blockage of the membrane, and the pretreatment process increases the complexity and operating cost of the equipment. The reverse osmosis method needs a high-pressure pump to provide enough pressure to drive the sea water through the membrane, so the energy consumption is high. SUMMARY

[0027] The utility model will be described in further detail below in combination with the drawings:

[0028] As Figure 1 shown, the utility model provides a kind of high-efficiency seawater desalination equipment, including equipment body;The first water inlet 1 is provided at the top of the equipment body;The first water inlet 1 and water distribution pipe 2 are connected;The water distribution pipe 2 and cooling tank 3 are communicated;Corresponding water collecting tank 5 is provided below the cooling tank 3;The water collecting tank 5 bottom is provided with water outlet pipe 6 communicated therewith;Water outlet 10 is arranged on the outer wall of the equipment body;The water outlet pipe 6 and water outlet 10 are communicated;Medium inlet 7 and medium outlet 8 are arranged on the outer wall of the equipment body;Heat exchange pipe 9 is arranged below the water outlet pipe 6;The heat exchange pipe 9 is connected with medium inlet 7 and medium outlet 8 respectively;Concentrated water outlet 12 is arranged at the bottom of the equipment body;Concentrated water collecting area 11 is arranged below the heat exchange pipe 9;The concentrated water collecting area 11 and concentrated water outlet 12 are communicated.

[0029] The first water inlet 1 is located at the top of the device body, facilitating the introduction of seawater. The device body is hollow inside, used for storing seawater and other components. The water distribution pipe 2 is connected with the first water inlet 1, uniformly distributing seawater into each cooling tank 3, ensuring the uniformity and efficiency of the desalination process. The seawater heated by the heat exchange pipe 9 forms steam, which contacts the cooling tank 3. The cooling tank 3 can realize steam condensation while recovering the heat in the steam to preheat the seawater. The water collecting tank 5 is located below the cooling tank 3, which can collect the condensed seawater and collect it into the water collecting tank 5, then introduce it into the water outlet pipe 6, and then flow out through the water outlet 10 for the collection of fresh water. The heat exchange pipe 9 is connected with the external environment through the medium inlet 7 and the medium outlet 8, forming a medium circulation. The heat exchange pipe 9 can use the heat exchange capacity of the medium to heat the seawater, so that the seawater rises to the cooling tank 3 to condense, improving the desalination efficiency. The concentrated water collecting area 11 below the heat exchange pipe 9 can collect the concentrated brine produced in the desalination process and discharge it through the concentrated water outlet 12, which helps to reduce the retention and pollution of concentrated brine and protect the marine ecological environment.

[0030] The heat exchange pipe 9 is a serpentine pipe. The backfolding design of the serpentine pipe can increase the heat exchange area, so that the heat of the medium is fully utilized to heat the seawater efficiently, improving the heat exchange efficiency.

[0031] The inner side wall of the device body is provided with a cavity, which is communicated with the cooling tank 3. The cavity is provided with a second water inlet 4, which is communicated with the inside of the device body. The seawater enters the bottom of the cooling tank 3 through the water distribution pipe 2 and reaches the cavity in the form of overflow, and then enters the inside of the seawater desalination device 3 through the second water inlet 4 provided on the side wall.

[0032] The end of the water distribution pipe 2 away from the first water inlet 1 is provided with a branch pipe 13. The branch pipe 13 extends into the cooling tank 3. The water distribution pipe 2 and the cooling tank 3 are communicated through the branch pipe 13. The setting of the branch pipe 13 makes the water distribution pipe 2 can more evenly distribute the introduced seawater to each cooling tank 3, which helps to ensure that the seawater in each cooling tank 3 can be fully cooled, thereby improving the efficiency of the whole seawater desalination process. Because the seawater is evenly distributed through the branch pipe 13, the deposition and blockage problem caused by excessive or insufficient water flow in some areas can be avoided, which helps to keep the cooling tank 3 unobstructed and ensure the smooth progress of the desalination process. At the same time, by introducing seawater into the cooling tank 3 through the branch pipe 13, the risk of loose or damage caused by water flow impact or vibration can be reduced, which helps to improve the overall reliability and service life of the equipment.

[0033] The cooling tank 3 is provided with a plurality of cooling tanks 3, and the branch pipe 13 is provided with a plurality of branch pipes 13 corresponding to the cooling tank 3. The setting of multiple cooling tanks 3 can further increase the processing capacity and improve the overall desalination efficiency.

[0034] The cooling tank 3 is inclined, and the inclination helps the uniform distribution and flow of seawater, reduces the risk of deposition and blockage, and improves the cooling effect.

[0035] The branch pipe 13 is vertically or inclined arranged, the vertical arrangement facilitates the flow of seawater and the maintenance of the equipment. When the branch pipe 13 is inclined, it is parallel to the cooling tank 3, which helps the uniform flow and distribution of seawater. Meanwhile, the branch pipe 13 extends to the bottom of the cooling tank 3, so that the newly flowed-in seawater can reach the bottom of the cooling tank 3, realizing the preheating of the newly flowed-in seawater and improving the condensation effect.

[0036] The water collecting tank 5 is circular arc-shaped, and the lowest point of the circular arc-shaped is communicated with the water outlet pipe 6, which helps the smooth gathering and discharge of seawater.

[0037] The water outlet pipe 6 is closed at one end and connected with the water outlet 10 at the other end. The water outlet pipe 6 is provided with a plurality of through holes on the side, which are communicated with the water collecting tank 5. The plurality of through holes can ensure the smooth discharge of seawater in the water collecting tank 5, and reduce the risk of blockage and deposition.

[0038] The working principle of the seawater desalination equipment is as follows:

[0039] The seawater enters the water distribution pipe 2 through the first water inlet 1, and the seawater in the water distribution pipe 2 is evenly distributed into the plurality of cooling tanks 3 through the branch pipe 13. When the seawater fills the cooling tank 3, it enters the cavity in the form of overflow, and then enters the equipment body from the second water inlet 4. The medium enters from the medium inlet 7, reaches the heat exchange pipe 9, heats the seawater in the equipment body, and then is discharged from the medium outlet 8. The heated seawater forms steam, which reaches the cooling tank 3 to be condensed, and at the same time, the steam preheats the seawater in the cooling tank 3. The condensed water droplets fall down and are collected by the water collecting tank 5 and introduced into the water outlet pipe 6, and then discharged from the water outlet 10 for collection. The non-evaporated part of the heated seawater forms concentrated brine and is collected in the concentrated water collecting area 11, and is discharged from the concentrated water outlet 12.

[0040] The above is only a preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
