Abstract
Provided is an anticorrosion tube-and-shell type heat exchanger. A heat exchange tube which is coaxial with a shell body is fixed between two fixed tube plates, and a tube-pass split-ranging partition board and the fixed tube plates are arranged on the inner wall of the shell body. The anticorrosion tube-and-shell type heat exchanger is characterized in that a circuit passage is formed by the tube-pass split-ranging partition board and the fixed tube plates through tube-pass liquid and an insulation tube is arranged on the joint of the outer wall of the heat exchange tube and the fixed tube plates. A sacrificial anode tube-pass split-ranging partition board is taken as an anode, metal atoms are electrolyzed to metal ions in the tube-pass liquid to supply electrons for the heat exchange tube, so that the corrosion process that atoms change to ions in the pipeline of the heat exchange tube is retarded or eliminated, the corrosion of the inner wall of the heat exchange tube is avoided, and thus the purpose of heat exchange tube protection is achieved. Meantime the anticorrosion tube-and-shell type heat exchanger is reasonable in design, simple in structure, long in service life, low in product cost, and can be popularized and used in all kinds of tube-and-shell type heat exchangers.

Background technology
In industrial production, for realizing a kind equipment of heat transfer process between the material, be referred to as heat exchanger.It is a kind of common apparatus of chemical industry, oil refining, power, the energy, atomic energy and other many industrial department extensive uses.For industry such as the chemical industry that develops rapidly, oil refining, heat exchanger is particularly important.Usually in the construction in chemical plant, heat exchanger accounts for 10～20% of gross investment.In oil plant, heat exchanger accounts for 35～40% of whole technological equipment investment.
In heat transmission equipment, most widely used is shell-and-tube heat exchanger.It is wide that it has selection range, the heat exchange surface easy to clean, and strong adaptability, treating capacity is large, can bear the characteristics such as high temperature and high pressure.To such an extent as to heat exchanger is the achievement that combines the each side such as thermal conduction study, applied mechanics, material science, metallurgical technology, manufacturing technology technical physics.Simultaneously, because the anxiety of the energy has been alleviated in the development of heat exchanger technology greatly.
Carrying out shell-and-tube heat exchanger when design, the material of the various parts and components of heat exchanger should be chosen according to the corrosive nature of the operating pressure of equipment, operating temperature, fluid and to the requirement of the manufacturing process performance of material etc.General operating pressure and operating temperature in order to satisfy equipment both considered from intensity or the rigidity of equipment, was the comparison easy to reach, but to the decay resistance of material, sometimes often became the problem of a complexity.As inconsiderate in this respect, selection is improper, not only can affect the life-span of heat exchanger, and greatly improves the cost of equipment.General heat exchanger mainly is that the temperature by different medium in tube side and the shell side realizes conducting heat.In the oil refining process, because the oil of refining contains H
2S, CO
2Deng corrosive gas, owing to the reasons such as burn into shock and vibration, stress can cause damage by heat exchanger, mainly occur on the heat exchanger tube, because of reasons such as corrosion and scalings, heat exchanger tube is extracted relatively difficulty out, and it is larger to change work difficulty, and tube-to-tube sheet connection mainly adopts Type of Welding to realize, in case replace tubes will affect normal production.In recent years, various countries have also obtained comparatively significant achievement in the research in heat exchanger anticorrosion field and design aspect, and such as the application of novel anticorrosion corrosion material, but new material involves great expense, and the popularization that shortcoming has restricted the heat exchanger aseptic technic such as are not easy to change.
Summary of the invention
In order to overcome the easy fouling of shell-and-tube heat exchanger and the hurtful problem of corrosion heat exchanging organ pipe in the prior art, the purpose of this utility model is to provide a kind of anti-corrosion pipe shell heat exchanger, has characteristics simple in structure, that effect is remarkable, convenient and practical.
In order to achieve the above object, the technical solution of the utility model is achieved in that
A kind of anti-corrosion pipe shell heat exchanger, comprise the Tube Sheet of Heat Exchanger 5 coaxial with housing, be provided with tube pass partition 1 and fixed tube sheet 3 in inner walls, tube pass partition 1 adopts conductive material, form circuit pathways by tube side liquid between tube pass partition 1 and the fixed tube sheet 3, the outer wall of Tube Sheet of Heat Exchanger 5 and fixed tube sheet 3 junctions are provided with insulation tube 8.
Described tube pass partition 1 adopts conductive material, is zinc or magnalium or magnalium Zinc material.
Described insulation tube 8 is the composite steel wire rubber sleeve.
The utility model is by adopting tube pass partition conductive material zinc or magnalium or magnalium Zinc material, zinc or magnalium, magnalium zinc are as anode, form circuit pathways with fixed tube sheet, anode is electrolyzed to produce metal ion by the anode metal atom in tube side liquid, for heat exchanger tube provides electronics, the corrosion process that makes the heat exchanger tube interior conduit be become ion by atom is slowed down or is eliminated, and has avoided the corrosion of heat exchanger tube inwall, has realized the purpose of protection heat exchanger tube; The utility model design protection scope is wide simultaneously; protect effective; and be easy on the structure realize; do not change other function of shell-and-tube heat exchanger; and can directly at labour Tube Sheet of Heat Exchanger checking maintenance the time, implement, can regularly replace, have the advantages such as reasonable in design, that antiseptic property good, product cost is low; prolonged the service life of heat exchanger, can in various shell-and-tube heat exchangers, promote the use of.
