Description
Technical field
The utility model relates in a kind of mechanical engineering field, uses the pipe separate fluid, with the heat exchanger of heat exchanger tube as basic heat exchange element, particularly removable double tubesheet shell-and-tube heat exchanger.
Background technology
In order to realize that the equipment of heat transfer process is referred to as heat exchanger between the material, be a kind of common processing equipment of industrial part extensive uses such as chemical industry, oil refining, power source.In heat transmission equipment, most widely used is shell-and-tube heat exchanger.The core curriculum of chemical industry specialty, process device and relevant close specialties such as control specialty, Refrigeration ﹠ Air-Conditioning, food engineering specialty, always being the emphasis content of courses as heat exchanger in the problems such as Principles of Chemical Engineering, chemical equipment machinery, process transmission, also is the scientific research and development emphasis of chemical industry equipment.The design of relevant experiment usefulness heat exchanger seldom.China's present stage teaching is a model with heat exchanger mostly, manyly all can not carry out plant-scale heat transfer experiment, the heat exchanger that promptly enables to carry out heat transfer experiment also can only carry out the change of limited parameter, structure is non-disconnectable, therefore can't carry out the experiments such as influence of heat exchanger structure to heat transfer property, the student can not see the heat exchanger internal structure personally.Therefore be badly in need of a kind of removable heat exchanger at present,, carry out a plurality of Experiments of Thermophysics and research work for the internal structure that the student understands shell-and-tube heat exchanger.
Aspect the removable research of heat exchanger, there are many patents open at present.As China Patent No. ZL00266937.4 disclosed " removable special-shaped double pipe heat exchanger ", ZL99220627.8 disclosed " removable barrel type heat exchanger ", ZL98240155.8 disclosed " flat cover sealing Demountable spiral-plate heat exchanger ", ZL98237453.4 disclosed " fast assembling-disassembling plate type heat exchanger ", ZL96249582.4 disclosed " high-efficiency detachable spiral-plate heat exchanger ", ZL96210262.8 disclosed " Demountable spiral-plate heat exchanger ", ZL94209301.1 disclosed " a kind of removable helical cavity heat exchanger ", ZL93228779.4 disclosed " removable coil exchanger ", ZL90224474.4 disclosed " removable ring barrel type heat exchanger ", ZL93101553.7 disclosed " dismountable plate type heat exchanger ", they all are removable heat exchangers, dirt will overlap tube bank or spiral plate Shu Kecong disassembles in the heat exchanger but they are just in order to clean, rather than heat exchanger tube, internal structures such as tube bank parts can singlely change fully.
Summary of the invention
Goal of the invention of the present utility model is experimental teaching, the scientific experiment that is suitable for heat exchanger in the correlated curriculums such as universities, scientific research institution's Principles of Chemical Engineering, Chemical Engineering, chemical industry equipment basis, also be applicable to the removable double tubesheet shell-and-tube heat exchanger of the heat exchange of fouling medium fluid easily such as chemical industry, pharmacy, to solve the weak point that existing heat exchanger exists.
In order to realize the foregoing invention purpose, the technical scheme that the utility model adopted is: removable double tubesheet shell-and-tube heat exchanger comprises the cylindrical shell of two band end sockets of cover flanges and a two ends band shell flange and inserts the heat exchanger tube in the cylindrical shell vertically and be arranged in deflection plate in the cylindrical shell vertically; It is characterized in that: also comprise being arranged between two end sockets and the cylindrical shell two ends, and by interconnective two groups of inside and outside tube sheets between bolt connection assembly and cover flange and the shell flange; On inside and outside tube sheet, all be arranged with concentric pore; The end socket at the pore connection cylindrical shell two ends on the inside and outside tube sheet is passed at the two ends of heat exchanger tube; Little the expanding of one end of heat exchanger tube is converted into diameter greater than the pore diameter on the outer tube plate; Between inside and outside tube sheet and heat exchanger tube, conical seal ring is housed.
The further technical scheme that the utility model adopted is: design has the concavity and convexity sealing surface and the plain cushion sealing ring is housed between inside and outside tube sheet and cover flange and shell flange.
The further technical scheme that the utility model adopted is: also comprise being installed in wherein also extending inward into cylindrical shell interior pull bar and some joint distance sink tubes vertically on an internal tube plate, some joint distance sink tubes and deflection plate compartment of terrain are installed on the pull bar by the nut of pull bar one end.
The utility model is behind the bolt connection assembly of opening between the cover flange at two ends, inside and outside tube sheet and the shell flange, and the end socket at two ends, cylindrical shell, tube bank are just detachably got off.On single heat exchange tube, apply external force, just single heat exchange tube can be changed from heat-exchanging tube bundle, inside and outside tube sheet and conical seal ring.Nut on the releasing lever just can be dismantled pull bar, thus detachable distance sink tube, deflection plate.Therefore the utility model internal structure is fully removable, be convenient to the student and understand the heat exchanger internal structure, also can study of the influence of heat-exchanging tube bundle structural parameters, also be fit in the actual process flow process because the easy structure of fluid needs the often occasion of cleaning shell dirt to heat transfer property and flow resistance.
Heat-exchanging tube bundle can be changed the heat-exchanging tube bundle annex after extracting out in the cylindrical shell easily, as deflection plate or rod baffle or baffling net, also can change the distance between the deflection element, studies by experiment in the hope of its optimum value.Heat exchange tube diameter is constant, change deflection plate pore size, or change gap between deflection element outer ring and the cylinder inboard wall and can study leakage stream between deflection plate and the heat exchanger tube, and the leakage stream between deflection element and the cylinder inboard wall is to the influence of heat transfer property and flow resistance.Reveal stream by research and can find out gap suitable between deflection plate pore and the heat exchanger tube etc., thereby propose rational machining accuracy, the existing good technical performance of heat exchanger can be made things convenient for rapidly again install.If adopt the tube sheet of different tube pitches, or change the heat exchanger tube arrangement mode, both can study the influence of tube pitch and stringing mode heat exchanging device performance and flow resistance.
The utility model is rational in infrastructure, is the device of a kind of desirable experimental teaching, scientific experiment, commercial Application, has simple in structure, mounting or dismounting convenience, good sealing effect, advantage such as easily manufactured.
