Description
Technical field
The utility model relates to a kind of heat-exchange apparatus, is a kind of vertical movable tube sheets heat exchanger of heatproof difference stress specifically, during this heat exchanger is mainly used in, the bigger operating mode of the low pressure two Cheng Leng thermal medium temperature difference.
Background technology
Heat exchanger is heat transmission between a kind of realization material, the process equipment that is widely used in industries such as oil, chemical industry, electric power, metallurgy, electric power, light industry, food, at present, the use amount maximum is shell-and-tube heat exchanger in heat transmission equipment, advantage is simple in structure, and applicability is strong.
In the heat transmission equipment running, when the cold and hot side temperature difference is big, adopt traditional U-shaped tubular type or movable tube sheets heat exchanger mostly, U-shaped pipe heat exchanger is applicable to HTHP, the less scaling occasion of the inside and outside medium cleaning of pipe, but the tube side circulation area is little, and flow resistance is big, and the easy fouling of bend loss can not be cleaned, so can not be used for big flow operating mode; Tradition movable tube sheets heat exchanger manufacturing cost is higher, raises the nose above water to breathe to leak in the as easy as rolling off a log appearance of end, also is difficult for hunting leak, and causes service life short.And this new structure design has overcome some above-mentioned shortcomings, compare down more simple in structure than traditional movable tube sheets heat exchanger, low cost of manufacture, leakage point is few, and reduced the heat transfer flow dead band, improved heat transfer property, during this new structure is specially adapted to, the bigger occasion of the low pressure two Cheng Lengre temperature difference.
Summary of the invention
The purpose of this utility model be to provide that a kind of rational in infrastructure, bearing capacity is strong, good seal performance, medium are difficult for stopping up, resistance drop is little, the novel floating type heat exchanger of heatproof difference stress.
The purpose of this utility model is to realize like this, this heat exchanger comprises housing 1, fixed tube sheet 2, heat exchanger main body 3, floating tubesheet 4, expansion joint 5, sealing support ring 6 and gripper shoe 7, described fixed tube sheet 2 is arranged on the inner upper end of housing 1, heat exchanger main body 3 is arranged between the following fixed tube sheet 2 and floating tubesheet 4 of fixed tube sheet 2, described floating tubesheet 4 is arranged on the lower end of heat exchanger main body 3, the following end that described expansion joint 5 is arranged on floating tubesheet 4 is connected on the floating tubesheet 4, the other end is connected with sealing support ring 6, and described sealing support ring 6 is fixedly connected at the lower interior of housing 1 by the gripper shoe 7 of a plurality of uniform settings.
The utlity model has following advantage and good effect:
1, the utility model can effectively solve two journey thermal (temperature difference) stresses by the expansion joint with bit shift compensation amount is set in equipment, reduces heat exchanger main body two ends and fixed tube sheet and floating tubesheet welding pulling-out force, has improved service life of equipment; It is strong to have bearing capacity, good seal performance, and medium is difficult for stopping up advantages such as resistance drop is little, heatproof difference stress.
2, the utility model be specially adapted to shell side import velocity of medium height,
Value is big and cause the occasion of heat exchanger body vibration easily.
,The utility model two Cheng Junwei single processes, the pure adverse current of two streams then more can obtain mean temperature difference between the two bigger streams than cross-flow or mixed flow, according to the heat transfer equation formula:
(
Overall heat-transfer coefficient,
-heat exchange area,
-mean temperature difference), as can be known, when thermic load one timing, improves mean temperature difference and can reduce heat exchanger area, reduce equipment cost.
,Traditional type segmental baffle shell-side fluid transversal flow tube bank in the past can make heat exchanger tube frontal impact and pipe backwash break away from vibration, causes that heat exchanger tube breaks and tube head leaks, and causes heat exchanger to reduce greatly service life.And this heat exchanger main body is longitudinal stream, and then the heat exchanger body vibration is little, and flow resistance is less, and the vibrationproof performance is strong, is not easy fouling;
5,There is the certain space flow dead in tradition segmental baffle formula heat exchanger shell-side, makes the heat exchanger effective heat exchange area reduce 25～30% than real area, adopts this new structure to effectively raise effective heat exchange area, reduces equipment size;
6,It is few that the seal leakage point is compared traditional movable tube sheets heat exchanger;
7,Tradition movable tube sheets heat exchanger complex structure, number of parts is many, and this utility model is simple in structure, and part is few, has not only reduced weight of equipment, and has shortened the device fabrication cycle;
8,Traditional movable tube sheets heat exchanger needs three pressure testings, and need suppress frock, and this new structure only needs the secondary pressure testing to get final product, and does not need to suppress frock.
