Abstract
The utility model relates to a heat exchanger with inhomogeneous heat exchange tubes. The utility model is composed of a shell body, a tube plate, a heat exchange tube, a baffling plate or a baffling rod, a draw rod, a tube box, a sealing head, a support seat, etc., wherein the heat exchange tube is an inhomogeneous heat exchange tube. The inhomogeneous heat exchange tube is composed of two sections, wherein one section has specific requirements on thickness, or material or anticorrosion treatment. The inhomogeneous heat exchange tube has three types which are respectively a heat exchange tube with unequal thickness, a heat exchange tube with different materials and a heat exchange tube with anticorrosion ends. The utility model has the advantages of easy manufacture, low cost of the heat exchange tube, long service life of the heat exchange tube, high performance-price ratio, development prospect and wide practical application.
Description
One, technical field
The utility model relates to a kind of heat exchanger tube of heat exchanger, especially the simple steel heat exchanger that uses under the high temperature.
Two, background technology
Heat exchanger be a kind of in industries such as oil, chemical industry and metallurgy widely used equipment, wherein shell-and-tube heat exchanger is because simple in structure, reliable operation, bearing capacity height have obtained extensive use at oil and chemical industry.At present, the heat exchanger tube that uses of shell-and-tube heat exchanger is the enhanced tubes such as plain tube, bellows, helix tube of uniform thickness.Usually heat exchanger in use; at the entrance point of shell-side fluid, heat exchanger tube in the certain-length scope, the easiest destruction; main cause is the particularly corrosive wear of liquid of fluid, also has reasons such as stress corrosion and slit erosion to cause the attenuation and the perforation destroy of heat exchanger tube in addition.Heat exchanger tube in the tube side fluid inlet end takes place under the situation of destruction, and the destructiveness at other positions of heat exchanger tube is lighter, and these positions can also continue to use usually.For this situation, whole heat transmission equipment scrapped, and just very waste adopts the exchange heat pipe to repair usually, continues the processing method of using then.Usually the restorative procedure that adopts is a heat exchanger tube liner replacement heat pipe; in addition, the measure of employing has: the heat exchanger heat-exchange tube patented technology that adopts heat exchanger tube and the using method (CN140739A) and the inside pipe wall coating polytetrafluoroethylene floor of composite heat exchange tube (CN2438092Y), a kind of high-temperature heat exchange tube tube head protection structure (CN2411402A), overlay coating.Cost was higher when these technology were used in engineering, and made trouble, and was unfavorable for being extensive use of.
Three, summary of the invention
In order to overcome the deficiency of existing heat exchanger tube resist technology, guarantee heat exchanger tube in use, produce evenly and destroy, thereby equipment is fully used, reduce equipment cost, heterogeneous body heat exchanger tube heat exchanger has been proposed.
The purpose of this utility model realizes by following measure.This heat exchanger is made up of housing [4], heat exchanger tube [7], tube sheet [10], deflection plate or rod baffle [6], pull bar [5], adapter [2], bobbin carriage and bearing parts such as [8], wherein heat exchanger tube belongs to the heterogeneous body heat exchanger tube, this heat exchanger tube has two sections formations, and other parts of heat exchanger still are the version in the common heat exchanger.The heterogeneous body heat exchanger tube can be plain tube, screwed pipe or other form, the plain tube form that preferential use is simple, price is low.The technical scheme of heterogeneous body heat exchanger tube has three kinds, and first kind of scheme is: two sections of the formations of heat exchanger tube, and material is identical, the thickness difference, the heat exchanger tube that is arranged in the inlet side of tube side fluid has the pipeline section of one section thickening, this heat exchanger tube to be called " not uniform thickness heat exchanger tube ".Second kind of scheme is: two sections of heat exchanger tube, thickness is identical, the material difference, and the heat exchanger tube material of main part is the words of carbon steel, the inlet side that is arranged in tube side fluid has one section stainless steel or pipe performance to be better than the pipeline section of main body tubing, and this heat exchanger tube is called " unlike material heat exchanger tube ".The third scheme is: two sections of heat exchanger tube, thickness is all identical with material, but preservative treatment difference in the pipe has one section inwall to apply the heat exchange pipeline section of polytetrafluoroethylene floor at the tube side fluid inlet side, all the other sections are not carried out preservative treatment, and this heat exchanger tube is called " the anticorrosion heat exchanger tube in end ".
Heterogeneous body heat exchanger tube heat exchanger, make simple, the heat exchanger tube cost is low, and the service time of heat exchanger tube is long, and the expense of heat exchanger tube has increase slightly, equipment service life special heat exchanger tube service life increase, viewpoint from value engineering, the equipment cost performance height of heterogeneous body heat exchanger tube heat exchanger, manufacturing technology is grasped easily, promising and application value.

Fig. 2 is uniform thickness heat exchange tube structure schematic diagram not;
Fig. 3 unlike material heat exchange tube structure schematic diagram;
The anticorrosion heat exchange tube structure schematic diagram in Fig. 4 end.
Five, the specific embodiment
Referring to figs. 1 through Fig. 4, this heat exchanger is made up of housing [4], tube sheet [10], heat exchanger tube [7], deflection plate or rod baffle [6], pull bar [5], bobbin carriage, end socket [1] and bearing parts such as [8], heterogeneous body heat exchanger tube [7] is used in the shell-and-tube heat exchanger, and requiring of the design of heterogeneous body heat exchanger tube heat exchanger and manufacturing and common heat exchanger is identical.The not manufacturing of uniform thickness heat exchanger tube can be carried out special manufacturing in steel mill and obtain, existing relevant patented technology, not the hydraulic pressure automatic machine tool of uniform thickness pipe; For the bigger heat exchanger tube of diameter, also can realize by the method that adopts every heat exchanger tube to weld drive sleeve.The manufacturing of unlike material heat exchanger tube, way is the method that every heat exchanger tube welds one section stainless steel tube easily.The tube side fluid entrance point that the anticorrosion heat exchanger tube in end can only be exchanged heat pipe carries out the preservative treatment of a segment length, realizes by inwall coating polytetrafluoroethylene floor or other measure.
