Abstract
The invention relates to a sleeve bundle for heat exchange. The sleeve bundle is mainly composed of straight tubes. According to the technical scheme adopted for solving the technical problems, the sleeve bundle for heathot exchange has a double-layer structure; an inner tube and an outer tube are both arranged as polished tubes; multiple sets of supporting plates are arranged in annular space between the inner tube and the outer tube; the inner tube, the outer tube and the supporting plates are formed into a sleeve component; a plurality of sleeve components are formed into a heat-exchange sleeve bundle; two cold fluid tube boxes are arranged on the outer sides of the tube openings at the two ends of the inner tube; the cold fluid tube boxes and the inner hole of the inner tube are formed into a cold fluid channel; a cold fluid inlet and a cold fluid outlet are respectively arranged on the two cold fluid tube boxes; a hot fluid annular space channel is formed by the annular space between the inner tube and the outer tube; annular space tube boxes are arranged at the two ends of the annular space channel; a hot fluid inlet is arranged on the upper part of the sleeve bundle; a hot fluid outlet is arranged on the lower part of the sleeve bundle; if air is taken as the cold fluid, the hot fluid flows in the annular space channel and the cooling water flows in the inner tube; the heat exchange on the outer side of the tube can be enhanced through the water spraying evaporation on the exterior of the outer tube. The sleeve bundle can be used for increasing the heat exchange efficiency of the cold and hot fluids.
Description
Technical field
The present invention relates to field of heat exchange equipment, be specifically related to the tube bank of a kind of sleeve pipe.
Background technology
Existing tube bank heat-exchanger rig, is made up of multiple single tube, cold fluid pipe in or outside pipe, with hot fluid septate heat transfer.Generally speaking, heat transfer coefficient in tubes is comparatively large, and it is less to manage outer heat transfer coefficient; The heat transfer coefficient in tubes of tubule is larger, but for thicker outer tube, under the prior art state not having pipe in insertion, hot fluid center in outer tube is exactly the center of outer tube, distance from hot fluid center to low-temperature receiver border is exactly outer tubing radius, in extra heavy pipe, the radius of hot fluid is large, and its heat transfer coefficient is just little; So people just wish naturally, while enhanced tube conducts heat outward, the intraductal heat transfer efficiency of strengthening extra heavy pipe.
Summary of the invention
The object of this invention is to provide a kind of sleeve pipe for heat exchange to restrain, to solve the problems referred to above of prior art.
The present invention forms primarily of straight tube, and solving technical scheme that its technical problem adopts is be double-decker for the sleeve pipe of heat exchange, and interior pipe, outer tube are light pipe, and the annular space between inner and outer pipes arranges some groups of gripper shoes; Interior pipe, outer tube and gripper shoe composition thimble assembly, the tube bank of some thimble assembly composition heat exchange sleeve; Arrange two cold fluid bobbin carriages outside the mouth of pipe of interior pipe two ends, cold fluid bobbin carriage and interior pipe orifice form cold fluid pass, and two cold fluid bobbin carriages arrange cold fluid import and cold fluid outlet respectively; Annular space space between inner and outer pipes forms hot fluid annular space passage, and the two ends of annular space passage arrange annular space bobbin carriage, the bottom that hot fluid import is arranged on the top of sleeve pipe tube bank, hot fluid outlet ports is arranged on sleeve pipe tube bank;
If take air as cold fluid, then hot fluid walks annular space passage, and cooling water walked by interior pipe; The outside of outer tube is carried out enhanced tube by trickle evaporation and is conducted heat outward.
Described gripper shoe is often organized as 2-4 sheet, and longitudinally symmetrical interval is arranged.
Good effect of the present invention is that in inserting after pipe, inner and outer pipe annular space is more much smaller than outer tubing radius, and annular space hot fluid center is just at half annular space place.Just sharply be reduced to half annular space from outer tubing radius from hot fluid center to the distance of the cold fluid of pipe, be also sharply reduced to half annular space from outer tubing radius from hot fluid center to the distance of interior pipe cold fluid.So the thermograde between Cooling and Heat Source just significantly strengthens, heat transfer power also just significantly strengthens, and heat output also just significantly increases.Here it is, and the reason of intraductal heat transfer strengthened by sleeve pipe.By adopting sleeve pipe tube bank, greatly improve the heat exchange efficiency of cold fluid and hot fluid.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is A-A sectional view.
In figure: pipe, 9 hot fluid imports, 10 hot fluid outlet ports, 11 coolant outlets in 1 cooling water tank, 2 annular space passages, 3 annular space bobbin carriages, 4 cooling water inlets, 5 outer tubes, 6 gripper shoes, 7 cooling-water ducts, 8.
Detailed description of the invention
As shown in the figure: the sleeve pipe for condensed steam is restrained, heat exchange sleeve is double-decker, annular space between inner and outer pipes arranges some groups of gripper shoes 6, interior pipe 8, outer tube 5, gripper shoe 6 form thimble assembly, the tube bank of some thimble assembly composition sleeve pipes, the mouth of pipe place, interior pipe 8 two ends of sleeve pipe arranges cooling water bobbin carriage 1 respectively, and cooling water bobbin carriage 1 forms cooling-water duct 7 with the endoporus of interior pipe 8, two cooling water bobbin carriages 1 is arranged respectively cooling water inlet 4 and coolant outlet 11; Annular space space between interior pipe 8 and outer tube 5 is steam annular space passage 2, and the two ends of annular space passage 2 arrange annular space bobbin carriage 3, and top, hot fluid outlet ports 10 that hot fluid import 9 is arranged on sleeve pipe tube bank are arranged on the bottom of sleeve pipe tube bank.Gripper shoe 6 is often organized as 2-4 sheet, and longitudinally symmetrical interval is arranged; The outside shower water falling film evaporation of outer tube carrys out enhanced tube and conducts heat outward.
