Abstract
Disclosed is a condenser for heating high pressure gas (steam), which belongs to the field of heat energy and power engineering. The condenser is composed of a high pressure gas (steam) inlet connection tube, a cylinder casing, a tube tank, a high pressure gas (steam) outlet connection tube, a saturated vapor inlet connection tube, a condensed fluid outlet connection tube, a support, a heat exchange finned pipe coil and a bypass flow baffle plate. The high pressure gas (steam) transversely scours a heat exchange core body, and flows out from a medium outlet after being heated by the saturated vapor in the heat exchange finned pipe coil. Compared with the conventional condenser, the condenser for heating high pressure gas (steam) is fine in heat transmission performance, and more compact and efficient in structure, further, each group of the heat exchange finned pipe coil is vertically arranged in the cylinder casing of the condenser, thereby being capable of effectively solving problems that the conventional condensing heater is not high in loading capacity and poor in heat exchange efficiency, and when a heat exchange tube is transversely arranged in the casing, the heated fluid only can scour the heat exchange tube vertically.
Description
Technical field:
Title of the present utility model is a kind of condenser that is applicable to the heating of high pressure gas (vapour) body, belongs to the Thermal Energy and Power Engineering field.
Background technology:
In industrial processes, usually need to heat or cool off the i.e. transmission of heat.When a kind of fluid and one other fluid are carried out heat exchange and do not allowed to mix, just require in recuperative heat exchanger, to carry out.The recuperative heat exchanger kind is a lot, wherein under the middle pressure situation, adopt shell-and-tube heat exchanger the most suitable, under high pressure, generally select the U-shaped heat exchange of heat pipe for use, this also is a kind of shell-and-tube heat exchanger in fact, if a kind of fluid generation condensation in the heat transfer process, then this shell-and-tube heat exchanger is a condenser.Though shell-and-tube heat exchanger is a kind of product of generalization, but in the different heat-transfer behavior of condition, because the polytropy of limitation, cold and hot logistics operation condition and the physical property of its structure, usually make the conventional design of shell-and-tube heat exchanger or condenser can not satisfy the needs on the engineering.
Undergo phase transition the condenser that is used for condensation heating for a kind of fluid in the heat transfer process, when thermal source is typically chosen in the shell side condensation of horizontal condenser during for saturated vapor, but when cooling medium pressure is higher, then adopt the tube side condensation more suitable.Yet when adopting the tube side condensation, often face such problem, promptly when heated medium is gas (vapour), the tube side condensation coefficient of this moment is much larger than gas (vapour) the body convection transfer rate of shell side, according to heat transfer principle, when the coefficient of heat transfer of heat exchanger two side liquids differs big, need the little fluid of heat exchanging coefficient one side to conduct heat and strengthen, for gas (vapour) body, generally adopt fin to strengthen.If adopt traditional shell-and-tube heat exchanger structure, promptly the heat exchanger tube lateral arrangement can cause fluid parallel baffled heat-exchanging tube bundle on the one hand in heat exchanger shell, is unfavorable for conducting heat; On the other hand, even install deflection plate additional at shell side, it is also inconvenient to install fin outside heat exchanger tube additional.In addition, it is square that traditional condenser shell mostly is greatly, and bearing capacity is limited, is not suitable for the operating mode of heated shell side pressure medium when higher.
The utility model proposes the thought of utilizing heat exchange wave-fin pipe vertically to be arranged in to be used in the heat exchanger cylindrical shell tube side condensation heating, problem such as can solve effectively that traditional condenser bearing capacity is not high, heat transfer property difference and structure are not compact.
The utility model content:
A kind of condenser that is applicable to high pressure gas (vapour) body heating that the utility model proposes can be used for that some need the occasion of heating high-pressure gas (vapour) body on the engineering, cooling medium is passed to outer gas (vapour) body of finned tube to heat by the heat exchange wave-fin tube bank that vertically is arranged in the condenser cylindrical shell, not only can farthest increase the bearing capacity of shell side, and can improve the heat-transfer behavior of condenser effectively, promptly need not increase under the condition of deflection plate, changing on the engineering conventional parallel baffled heat-exchanging tube bundle is transversal flow, make full use of simultaneously finned tube this in the process of improving the pipe type heat transfer face the earliest, the most successful, to the very effective intensified heat transfer method of gas (vapour) body heat exchange.Therefore, the utility model is to condenser applying and energy-saving and cost-reducing having great importance at some special occasions.
For solving the problems of the technologies described above, the utility model is a kind of to be applicable to that the technical scheme of the condenser that high pressure gas (vapour) body heats is as follows:
A kind of condenser that is applicable to high pressure gas (vapour) body heating of forming by high pressure gas (vapour) body entrance sleeve, cylindrical shell, bobbin carriage, high pressure gas (vapour) body discharge connection, saturated vapor entrance sleeve, condensate outlet adapter, bearing, heat exchange wave-fin pipe and by-pass flow baffle plate, high pressure gas (vapour) body is entered the heat exchange core body that is made of heat exchange wave-fin pipe by the medium entrance sleeve, high pressure gas (vapour) body transversal flow heat exchange core body is taken over outflow by the heating of the saturated vapor in heat exchange wave-fin pipe back by media outlet; Saturated vapor is entered by the saturated vapor entrance sleeve, and the back that is condensed in heat exchange wave-fin pipe is taken over by condensate outlet and flowed out; High pressure gas (vapour) body import and export is taken over the upper and lower part that lays respectively at the condenser left and right sides; Saturated vapor at first enters the female pipe of steam that is arranged in heat exchange wave-fin tube bank top, is evenly distributed to then in every group of heat exchange wave-fin pipe; The condenser two ends are bobbin carriage; Every group of heat exchange wave-fin pipe vertically is arranged in the condenser cylindrical shell, and is fork row between the two adjacent groups heat exchange wave-fin pipe; For improving the flow condition of shell side gas (vapour) body, the by-pass flow baffle plate also is installed at the condenser shell side.
The utility model is characterised in that and adopts high-efficiency fin pipe heat exchange surface to replace traditional light pipe heat exchange surface, and every group of heat exchange wave-fin pipe vertically is arranged in the condenser cylindrical shell, saturated vapor flows in finned tube after managing uniform distribution by a steam is female, heated medium can be a gas, also can be steam, manage outer fin and adopt the ratio-frequency welding ring fin.Compare with traditional condenser, good heat-transfer, structure compact efficient more not only, and every group of heat exchange wave-fin pipe vertically be arranged in the condenser cylindrical shell, can solve effectively that traditional condensation heater bearing capacity is not high, heat exchanger tube is heated fluid during lateral arrangement in housing can only the parallel baffled heat exchanger tube, the problem of heat exchange weak effect.
Description of drawings:
Fig. 1 is a kind of structure of condenser figure that is applicable to high pressure gas (vapour) body heating, Fig. 2 be among Fig. 1 A, B to perspective view.Wherein: 1-high pressure gas (vapour) body entrance sleeve; The 2-cylindrical shell; The 3-bobbin carriage; 4-high pressure gas (vapour) body discharge connection; 5-saturated vapor entrance sleeve; The 6-condensate outlet is taken over; The 7-bearing; 8-heat exchange wave-fin pipe; 9-by-pass flow baffle plate.
The specific embodiment:
Fig. 1 also represents the structure of condenser of a saturated vapor that comes out from certain storage heater with HTHP saturated vapor heating.
