Description
Technical field
The utility model relates to heat exchanger technology, particularly a kind of removable experiment heat exchanger.
Background technology
Since the nineties in last century, the heat exchanger technology develop rapidly, the raising that has brought energy utilization rate, the exploitation in succession and the application of various new type heat exchangers have produced the huge social economic benefit.Along with the day of world energy sources is becoming tight, the continuous rising of global temperature, the exploitation of energy-saving equipment gets most of the attention, and the raising of environmental protection requirement has brought wide day by day application prospect to heat exchanger.
From present situation, heat exchanger mainly develops towards miniaturization, high efficiency, low consumptive material, multipurpose direction.At present, both at home and abroad how each research institution has invested improvement by heat exchanging organ pipe journey or shell side (for example change between tube construction form, mounting pipe and in the pipe insert etc.) to main sight and has reached on the heat exchange efficiency of raising heat exchanger, has ignored in the improvement of the heat exchanger self that experimental study is used.At present the used shell-and-tube heat exchanger of experimental study all is the heat exchanger of non-disconnectable (tube-to-tube sheet connection expanded joint or weld together) basically, and the utilization rate of equipment is low, the experimental cost height, and thermal (temperature difference) stress is big between shell, cleans inconvenience between pipe.If change a kind of cast or shell side structure experimentizes, must rebulid experimental bench and the new suitable heat exchanger of design.In order to overcome the shortcoming of this respect, the dismountable heat exchanger of a kind of heat exchanger tube is disclosed in the patent No. is 200420040170.4 Chinese utility model patent, the end plate that comprises heat exchanger tube and heat exchanger tube two ends, the end plate at described heat exchanger tube two ends constitutes double-decker by inner end plate, outer end plate, design has pore on inner end plate and the outer end plate, heat exchanger tube is inserted through the pore of inner end plate, and outer end plate and inner end plate are fixed; The inner end plate outside respectively is provided with closure gasket groove outside pore, put sealing ring on the heat exchanger tube, and outer end plate is pressed into sealing ring in the closure gasket groove on the inner end plate.Though this dismountable frame mode can be realized dismountable effect, but still there is obvious defects: because it only is provided with closure gasket groove in the inner end plate outside outside pore, closure gasket groove is not set in the corresponding position of outer end plate, the sealing ring that only relies on outer end plate to be squeezed in the closure gasket groove is realized sealing, so it can only use the less relatively sealing ring of size, its bearing capacity is relatively low like this; In addition, because the space in the closure gasket groove is less, so tighter relatively to the size restrictions of sealing ring, the sealing ring size has error promptly can not realize sealing preferably slightly; In addition, the heat exchanger of this structure is not exchanged heat pipe and is axially being formed restriction, so it does not solve
Axially movable problem takes place in heat exchanger tube under higher differential pressure.
The utility model content
The shortcoming that the purpose of this utility model is to overcome prior art provides a kind of simple and reasonable for structure, easy to use, good pressure-resistant performance, removable experiment heat exchanger safe and reliable to operation with not enough.
The purpose of this utility model is achieved through the following technical solutions: a kind of removable experiment heat exchanger, the tube sheet that comprises heat exchanger tube and heat exchanger tube two ends, the tube sheet at described heat exchanger tube two ends is by internal tube plate, outer plate constitutes double-decker, design has pore on tube sheet and the pressing plate, heat exchanger tube is inserted through the pore of tube sheet, it is characterized in that: the pore of described tube sheet and pressing plate all is provided with annular groove outward, the relative closure gasket groove that forms of annular groove of tube sheet and pressing plate, described heat exchanger tube passes the pore of tube sheet and pressing plate, be provided with sealing ring in the described closure gasket groove, described sealing ring is socketed on the heat exchanger tube.
In order to guarantee the better seal effect, can adopt two O-ring seals to be set up in parallel the form that seals in closure gasket groove, also can adopt single B V-shaped ring to be arranged at the form that closure gasket groove seals, this has better sealing effectiveness with respect to the structure that adopts single O-ring seals, and withstand voltage properties is higher.Better if desired sealing effectiveness can adopt the octagonal sealing ring.
Move axially under higher differential pressure for fear of heat exchanger tube, pore that can outer plate is set to stepped bore, and the ladder in described heat exchanger tube and the stepped bore is apical grafting mutually, and the effect that the holds out against axial restraint heat exchanger tube by ladder makes sealing property more reliable.
The utility model has following advantage and effect with respect to prior art: this removable experiment with heat exchanger owing to the space that has enlarged closure gasket groove, can a plurality of sealing rings be set or adopt the bigger sealing ring of sectional area at closure gasket groove, so it is except having conveniently removable, as to help experimental implementation effect, also has shell side sealing effectiveness preferably, voltage endurance capability is better, moves more safe and reliable; On the other hand, owing to be provided with hierarchic structure in the pore of outer plate, avoided heat exchanger tube to move axially under higher differential pressure by the effect of holding out against of ladder, so structure of the present utility model is more firm, fault rate is lower.
