Wherein, 1, cylindrical shell, 2, upper perforated plate, 3, lower perforated plate, 4, heat pipe, 41, protruding gear, 5, packing ring, 6, interior ring sealing ring, 7, outer shroud sealing ring, 8, regulate pad.
Detailed description of the invention
As shown in Figure 1, a kind of heat exchanger that improves heat pipe installation sealing, comprise cylindrical shell 1, upper cover, upper perforated plate 2, low head and lower perforated plate 3, material inlet is set on low head, material outlet is set on upper cover, the middle part of cylindrical shell 1 arranges some heat pipes 4, the upper end of heat pipe 4 through upper perforated plate 2 be communicated with material outlet and and upper perforated plate 2 form and be sealed and matched, the lower end of heat pipe 4 is communicated with material inlet through lower perforated plate 3 and forms and be sealed and matched with lower perforated plate 3, cylindrical shell 1 upper end arranges steam inlet, and the lower end of cylindrical shell 1 arranges condensate outlet.
As shown in Figure 2, the sealing installation structure between heat pipe 4 and upper perforated plate 2 is, heat pipe 4 upper ends form protruding gear 41, and the heat pipe 4 of protruding gear 41 tops is through upper perforated plate 2 connecting bolts, and between protruding gear 41 and upper perforated plate 2, cambered surface is sealed and matched.Between bolt and upper perforated plate 2, be provided with packing ring 5, be positioned on the upper perforated plate 2 of packing ring 5 belows and be provided with sealed groove, be positioned at the adjusting pad 8 of sealing groove, between adjusting pad 8 and heat pipe 4, form spiral and coordinate, interior ring sealing ring 6 and outer shroud sealing ring 7 below adjusting pad 8.Rotating adjusting pad 8 can be by interior ring sealing ring 6 and outer shroud sealing ring 7 bottom land that is fitted in sealed groove tightly, avoids the phenomenon that occurs that high-temperature steam is revealed.
Sealing installation structure between heat pipe 4 and lower perforated plate 3 is that the lower end of heat pipe 4 is passed lower perforated plate 3 and formed spiral with lower perforated plate 3 and coordinates, and between heat pipe 4 and lower perforated plate 3, is provided with fluid sealant.Between heat pipe 4 lower ends and lower perforated plate 3, can form free adjustment like this, thereby can make the degree of tightness between heat pipe 4 upper end free adjustment and upper perforated plate 2, be i.e. distance between cambered surface and the upper perforated plate 2 of the heat pipe 4 protruding gears 41 in upper end.
