Abstract
The utility model discloses a tube-and-shell type heat exchanger, and relates to the technical field of heat exchanger manufacturing. The tube-and-shell type heat exchanger comprises heat exchange tubes and inserts inserted into the heat exchange tubes, and a heat conduction metal layer is arranged on the surface of one of each heat exchange tube and each insert. Each heat conduction metal layer is one coating layer of a cold layer, a silver layer, a copper layer, a nickel layer and a zinc layer. Compared with the prior art, the tube-and-shell type heat exchanger makes contact of the inserts and the heat exchange tubes to be better, and heat transfer efficiency is higher. Purity of the heat conduction metal layers are higher than that of materials of the heat exchange tubes or insert bodies, the comprehensive heat transfer effect of the surfaces formed by the coatings and heat exchange media is better than that of heat exchange elements without coatings, and the heat transfer effect is efficient, and the tube-and-shell type heat exchanger is energy-saving and reliable.
Description
Technical field
The utility model relates to heat exchanger manufacturing technology field, especially a kind of shell-and-tube heat exchanger that gas is cooled off of being used for.
Background technology
Shell-and-tube heat exchanger is widely used in industries such as electric power, chemical industry, accounts for 70% of heat exchanger total amount; Along with the development of society, the consumption of the energy and material sharply increases, and saving energy and reduce the cost becomes the important research and development direction of every profession and trade, and the increase of the energy and material cost makes that heat exchange efficiency height, the energy-efficient heat exchanger that volume is little obtain paying attention to.Have a kind of technical scheme of shell-and-tube heat exchanger to be: include a housing and be contained in the interior heat exchanger fuse of this housing, described heat exchanger fuse has many heat exchanger tubes that are inserted between tube sheet and the internal tube plate, is fitted with the interpolation thing in the every described heat exchanger tube.In use there is following deficiency in the technical scheme of this shell-and-tube heat exchanger: because the tube wall surface and the heat exchanger tube interpolation thing of heat exchanger tube are rough, easy incrustation and heap dirt, the heat exchanger tube thermal resistance is increased, cause the overall heat exchange effect of heat exchanger to descend; Functional reliability is bad.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of shell-and-tube heat exchanger that dirt is heaped at heat exchanger tube that prevents that better heat exchange effect is arranged.
The technical scheme that the utility model technical solution problem is adopted is: this shell-and-tube heat exchanger includes heat exchanger tube and is inserted into the interior interpolation thing of described heat exchanger tube, has at least a kind of surface of part to be provided with heat-conducting metal layer in described heat exchanger tube and the described interpolation thing.
In the aforementioned tube shell heat exchanger technical scheme, technical scheme can also be more specifically: described heat-conducting metal layer is a kind of coating in gold layer, silver layer, copper layer, nickel dam, the zinc layer.
Owing to adopted technique scheme, the utility model compared with prior art, the beneficial effect that has is:
1, make heat exchanger tube or interpolation beyond the region of objective existence see smooth surface, less scaling, be difficult for combining with dirt, thus make heat-transfer effect good.
2, make the interpolation thing better with contacting of heat exchanger tube, heat transfer efficiency is higher; Relative heat exchanger tube of the purity of heat-conducting metal coating or interpolation thing bulk material purity height, the relative heat exchange element that does not have coating with the complex heat transfer effect of heat transferring medium in surface that coating forms will be got well; Whole heat exchange effect is more efficient, energy-conservation, reliable.

The specific embodiment
Embodiment 1
Shell-and-tube heat exchanger as shown in Figure 1 and Figure 2 include tube sheet 10 and internal tube plate 5 and be inserted into tube sheet 10 and internal tube plate 5 between many heat exchanger tubes 6, every heat exchanger tube 6 interior all interpolation things 8 of plug-in mounting, present embodiment the surface of heat exchanger tube 6 is provided with heat-conducting metal layer at heat exchanger tube 6 and interpolation thing 8 among both, heat-conducting metal layer is preferably a kind of coating in the high gold layer of thermal conductivity, silver layer, copper layer, nickel dam, the zinc layer, and coating is obtained by the mode of chemical plating, mechanical plating or plating.The heat-conducting metal layer of present embodiment is the copper layer, and it adopts hot dip mode in the plating at heat exchanger tube 6 surperficial plated with copper layers.
During work, need the hot gas of cooling to enter shell-and-tube heat exchanger, after the surface and the cooling medium of heat exchanger tube 6 inner surface of tube wall and interpolation thing 8 carry out the heat exchange cooling, from bobbin carriage 4 outflows of giving vent to anger from air inlet bobbin carriage 1; Cooling water enters from water inlet 3, the runner that heat exchanger tube 6 outer surface of tube wall and housing 2 and the deflection plate 7 of flowing through forms and carry out heat exchange after flow out from delivery port 9.When gas is flowed through heat exchanger tube 6,, make tube wall smooth because heat exchanger tube 6 inner surface of tube wall have the copper layer to exist, dirt in the gas is difficult in inner surface of tube wall incrustation or accumulation, gas passage does not have the little of copper layer relatively because of the thermal resistance that dirt causes, and therefore, gas passage heat exchange effect is strengthened.Cooling water flow is when heat exchanger tube 6 outer surface of tube wall copper layers, because the existence of copper layer, the surface is less scaling, and while copper layer heat conductivility is preferably strengthened cooling water channel heat exchange effect.
Embodiment 2
As Fig. 1, shell-and-tube heat exchanger shown in Figure 3 include tube sheet 10 and internal tube plate 5 and be inserted into tube sheet 10 and internal tube plate 5 between many heat exchanger tubes 6, every heat exchanger tube 6 interior all interpolation things 8 of plug-in mounting, present embodiment is provided with heat-conducting metal layer on the surface of heat exchanger tube 6 and the interpolation thing 8 interpolation thing 8 among both, heat-conducting metal layer is preferably a kind of coating in the high gold layer of thermal conductivity, silver layer, copper layer, nickel dam, the zinc layer, and coating is obtained by the mode of chemical plating, mechanical plating or plating.The heat-conducting metal layer of present embodiment is a nickel dam, and it adopts the mode of chemical plating to plate nickel dam on heat exchanger tube 6 surfaces; Other features are identical in embodiment 1.
