Embodiment 1
[0034] figure 1 It is a structural schematic diagram of a condenser according to an embodiment of the present invention. figure 2 It is a left view structural schematic diagram of the condenser of Embodiment 1 of the present invention, in figure 2 In , the right front water chamber is disassembled to show the arrangement of the heat exchange tubes of the condenser end tube plate. image 3 It is a schematic sectional view (half side) of the three-dimensional structure of the condenser of Embodiment 1 of the present invention.
[0035] exist figure 1 , figure 2 and image 3 Among them, condenser water chamber 1 is divided into front water chamber and rear water chamber, each with 2 pieces, condenser end tube plate 2 is divided into front end tube plate and rear end tube plate, each with 2 pieces, middle tube plate 3 It is arranged symmetrically on both sides, with 11 pieces on each side, the middle tube plate 3 has 2×11=22 pieces, and several heat exchange tubes 4 (in th...
Embodiment 2
[0047] Figure 9 It is a structural schematic diagram (half side) of the mid-section of the condenser of Embodiment 2 of the present invention. exist Figure 9 Among them, the tube bundle of the half-side condenser in this embodiment is a double bionic tree-shaped tube bundle of an umbrella-shaped air-cooling zone symmetrically arranged, and each bionic tree-shaped tube bundle (independent main cooling tube bundle unit) consists of 5575 heat exchange tubes Composition, each adjacent tapered air-cooled area tube bundle (independent air-cooled tube bundle unit) is composed of 391 heat exchange tubes, and the tube bundle arrangement of the half-side condenser in this embodiment has a total of 11932 heat exchange tubes. There are 23864 heat exchange tubes in the condenser.
[0048] exist Figure 9 Among them, the air-cooled steam baffle assembly 7 and the two tapered air-cooled zone tube bundles (A1 and A2) and the evacuation pipe 6 form an "umbrella" shape. The difference from...
Embodiment 3
[0052] Figure 10 It is a schematic diagram (half side) of the middle section structure of the condenser of embodiment three of the present invention, Figure 11 yes Figure 10 A schematic diagram of the local structure.
[0053] exist Figure 10 and Figure 11 Among them, the air-cooled steam baffle assembly 7, the air-cooled connecting pipe 12, the two tapered air-cooled zone tube bundles and the evacuation pipe 6 form an "umbrella" shape, wherein the upper steam baffle 701 and the air-cooled connecting pipe 12 are shaped like an "umbrella" The vertical steam baffle 702 and the evacuation pipeline 6 are shaped like a "vertical" in the middle of the word "umbrella". There is a certain gap between the two vertical steam baffles 702, and 703 is "umbrella". The Chinese-shaped horizontal steam plate is shaped like a "horizontal" in the middle of the word "umbrella". The upper space of " font communicates with the air-cooling connecting pipe. exist Figure 10 and Figure 1...
