Abstract
The utility model discloses a shell-and-tube heat exchanger which enables a medium to flow more smoothly. The shell-and-tube heat exchanger comprises a plurality of heat exchange tubes, a cylinder, an upper tube plate and a lower tube plate arranged on the upper end and the lower end of the cylinder respectively, wherein the upper tube plate and the lower tube plate are provided with a tube box and a lower seal head respectively; the upper end of the tube box is provided with an upper seal head; two ends of the heat exchange tube are arranged in the tube holes of the upper tube plate and the lower tube plate respectively in a penetrating manner; a conic guiding surface which is wide at top and narrow at bottom is arranged at the top of the tube hole of the upper tube plate; the upper end surface of the heat exchange tube is lower than the lower edge of the conic guiding surface. For the shell-and-tube heat exchanger, by arranging a conic guiding surface at the top of the tube hole of the upper tube plate to eliminate the flow blind angles, medium can flow more smoothly.
Description
Technical field
The utility model relates to heat exchanger, refers more particularly to shell-and-tube heat exchanger.
Background technology
At present, shell-and-tube heat exchanger conducts heat by the pipe wall.Have firm in structure, reliable, adaptability strong, be easy to make, can bear advantages such as higher operating pressure and temperature.In high temperature, high pressure and large heat exchanger, have comparative advantage, be a present most popular class heat exchanger.
" conical head shell-and-tube heat exchanger " is a kind of in the shell-and-tube heat exchanger, is mainly used to handle the chemical textile dyestuff of thickness.Can there be some problems as the fluidal texture that designs this type of medium with conventional design.Because of its medium has thickness, little poison and characteristic such as certain corrosivity is arranged, even its distinctive viscosity medium is keeping the stationary temperature current downflow also to be difficult to guaranteeing to flow very smooth.As make the flow blind angle that outstanding tube head of heat exchanger tube and tube sheet are formed by the existing conventional heat exchanger tube and the Welding Structure pattern of tube sheet; In addition because the position at the tube sheet tie rod hole back side is the stagnant area of the same easy formation of large-area planar (other coordinatioies are changed to heat exchanger tube).There are above-mentioned flow blind angle and stagnant area to exist, not only influence the smooth flow of medium, influence the performance of medium thereby understand come off in certain cycle at the medium of flow blind angle and stagnant area simultaneously.
The utility model content
Technical problem to be solved in the utility model is: a kind of shell-and-tube heat exchanger more smoothly that flows that makes medium is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: shell-and-tube heat exchanger, comprise: some heat exchanger tubes, cylindrical shells and be separately positioned on the upper and lower tube sheet of cylindrical shell upper and lower side, be respectively arranged with bobbin carriage and low head on the upper and lower tube sheet, the upper end of bobbin carriage is provided with upper cover, the two ends of described heat exchanger tube are located in respectively in the pore of upper and lower tube sheet, the top of described upper perforated plate pore is provided with taper guide face wide at the top and narrow at the bottom, and the upper end end face of described heat exchanger tube is lower than the lower edge of taper guide face.
The back side of described upper perforated plate is provided with deflection plate by pull bar, and the position that faces pull bar of upper perforated plate is provided with fair water cone.
Described fair water cone is conical fair water cone.
Described upper and lower end socket is conical head.
The beneficial effects of the utility model are: the utility model is provided with the taper guide face at the top of upper perforated plate pore, make the porch of every heat exchanger tube be equivalent to a slight taper guide shell, reduced the choked flow effect of the mouth of pipe to medium, quicken the mild of medium to a great extent and flowed, also avoided the generation at dead angle simultaneously; In addition, be arranged on the fair water cone on the flat part that the upper perforated plate back side faces pull bar, the medium that makes thickness directly flows down and is distributed to and flows downward in its peripheral heat exchange mouth of pipe along conical cap, thereby reduces the delay of medium in this district, makes that flowing of medium is more smooth and easy.
