specific Embodiment 1
[0033] Specific embodiment 1: (spherical seawater desalination device)
[0034] In this example, the seawater desalination device is made into a spherical shape, and the half-section diagram is as follows Figure 4 As shown, the anatomical diagram is as Figure 5 As shown, the transparent airtight casing is divided into upper and lower hemispherical casings, the upper casing 1A-1 and the lower casing 1A-2, both are single-layer or double-layer thin-walled, and the junction of the two hemispheres is sealed. Seawater first enters the upper water column 8A from the second hole 12-2 of the connector 12, and then enters the condenser 3A. The condensation area is the area between the bowl-shaped condenser outer edge 3A-1 and the isolation cover 6A, and the isolation cover 6A The size of the outer edge is required to be larger than the outer edge 3A-1 of the bowl-shaped condenser, and slightly smaller than the inner wall of the air-drying evaporator, that is, the projection of the i...
specific Embodiment 2
[0038] Specific embodiment 2: (the columnar seawater desalination device that does not have natural convection circulation artificial enhancement system)
[0039] In this example, the described seawater desalination device is made into a column, and the overall sectional view is as follows Figure 10 As shown, the transparent airtight shell is divided into upper and lower parts, the upper part is a hemispherical upper shell 1B-1, and the lower part is a cylindrical lower shell 1B-2, both of which are single-layer or double-layer thin-walled, and the two parts are combined sealed. Seawater first enters the condenser 3B from the upper water column 8B. The condensation area is the area between the isolation cover 6B and the wall 1B-2-1 in the cylindrical lower shell 1B-2. Layers are spirally arranged to increase the heat transfer area as much as possible. Figure 10 not shown in the Figure 4 The rib plate 14) in the wall is used as a support, and the seawater conducts heat ex...
specific Embodiment 3
[0040] Specific embodiment 3: (with the columnar seawater desalination device of natural convection circulation artificial enhancement system)
[0041] In this example, the described seawater desalination device is made into a column, and the overall sectional view is as follows Figure 11 As shown, the transparent airtight casing is divided into upper and lower parts, the upper part is a hemispherical upper casing 1C-1, and the lower part is a cylindrical lower casing 1C-2, both of which are single-layer or double-layer thin-walled, and the two parts are combined sealed. Seawater first enters condenser 3C by upper water column 8C, and condensation area is the condenser outer edge 3-1 of isolation cover 6C and bowl shape (as Figure 12 In the area between shown), the condensation pipes in the condenser 3C are arranged in a three-layer helical arrangement inside, middle and outside to maximize the heat exchange area. Figure 11 not shown in the Figure 4 The rib plate 14) in...
