Abstract
The invention discloses a shell-and-tube heat exchanger and relates to the technical field of exchangers. The shell-and-tube heat exchanger comprises a plurality of heat exchange tubes which are mounted between a tube plate and an inner tube plate in an insert manner, a heat conducting metal layer is coated on the surface of each heat exchange tube, and each of the heat conducting metal layers is selected from one of a golden layer, a silver layer, a copper layer, a nickel layer and a zinc layer. Compared with the prior art, the shell-and-tube heat exchanger has the advantages that heat conducting effect is good and working reliability is high since the heat exchange tubes are smooth in surfaces, not easy to scaling and combine with dirt; the purity of the metal material of the heat conducting metal coating layers is higher than that of the material of the heat exchange tubes, comprehensive heat conducting effect of the surface of the coated layers and heat exchange medium is better than that of an uncoated heat exchange element; and an integral heat exchange effect is more efficient, energy-saving and reliable.
Description
Technical field
The present invention relates to the heat exchanger technical field, especially a kind of shell-and-tube heat exchanger for gas is cooled off.
Background technology
Shell-and-tube heat exchanger is widely used in the industries such as electric power, chemical industry, accounts for 70% of heat exchanger total amount; Development along with society, the consumption of the energy and material sharply increases, the energy-saving and cost-reducing important research and development direction of every profession and trade that becomes, and the increase of the energy and material cost so that the high-effect energy-saving heat-exchanger that heat exchange efficiency is high, volume is little paid attention to, the technical scheme of shell-and-tube heat exchanger commonly used roughly is at present: include a housing and be contained in the interior heat exchanger core of this housing, described heat exchanger core has many heat exchanger tubes that are inserted between tube sheet and the internal tube plate, and described heat exchanger tube is long light-wall pipe.In use there is following deficiency in the technical scheme of this shell-and-tube heat exchanger: because the heat exchanger tube tube wall is rough, easily incrustation and heap dirt so that the heat exchanger tube thermal resistance increases, cause the overall heat transfer effect of heat exchanger to descend.
Summary of the invention
Technical problem to be solved by this invention provides the shell-and-tube heat exchanger that a kind of prevented dirt that better heat transfer effect arranged is heaped at heat exchanger tube.
The technical scheme that technical solution problem of the present invention adopts is: this shell-and-tube heat exchanger comprises many heat exchanger tubes that are inserted between tube sheet and the internal tube plate, and the surface of every described heat exchanger tube is equipped with heat-conducting metal layer.
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 having adopted technique scheme, the present invention compared with prior art, the beneficial effect that has is: 1, make the heat exchanger tube appearance surfaces smooth, less scaling, be difficult for being combined with dirt, thereby make heat-transfer effect good, functional reliability is high.2, the relative heat exchange pipe body material purity of the metal material purity of heat-conducting metal coating is high, and surface the heat exchange element without coating relative to the complex heat transfer effect of heat transferring medium that coating forms will be got well; The overall heat exchange effect is more efficient, energy-conservation, reliable.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the structural representation of the heat exchanger tube of the embodiment of the invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
Shell-and-tube heat exchanger as shown in Figure 1 and Figure 2 comprises the many heat exchanger tubes 6 that are inserted between tube sheet 9 and the internal tube plate 5, and the surface of every heat exchanger tube 6 is equipped with heat-conducting metal layer; Heat-conducting metal layer is a kind of in thermal conductivity high gold layer, 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 the 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 from air inlet bobbin carriage 1, after heat exchanger tube 6 inner surface of tube wall and cooling medium carry out the heat exchange cooling, from bobbin carriage 4 outflows of giving vent to anger; Cooling water enters from water inlet 3, the passage 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 8; When gas flow during through heat exchanger tube 6 inner surface of tube wall copper layer, because the existence of copper layer makes tube wall smooth; Dirt in the gas is difficult for sending out incrustation or accumulation at tube wall surface, and the thermal resistance that the gas flow passage causes because of dirt does not have the little of copper layer; Therefore, the gas passage heat transfer effect is strengthened.Cooling water flow is when heat exchanger tube 6 outer surface copper layer, because the existence of copper layer, the surface is less scaling, and while copper layer preferably heat conductivility is strengthened the cooling water channel heat transfer effect.
Claims (2)
1. a shell-and-tube heat exchanger comprises many heat exchanger tubes that are inserted between tube sheet and the internal tube plate, and it is characterized in that: the surface of every described heat exchanger tube is equipped with heat-conducting metal layer.
