Description
Technical field
The utility model relates to a kind of split type middle discharge opeing condenser system, and being mainly used in gas or steam condensing is liquid.
Technical background
The condensation condensation heat transfer that comprises steam condensing mainly contains two kinds of forms: a kind of is film condensation; Another kind is pearl (dripping shape) condensation.Pearl condensation, its surface coefficient of heat transfer is than large several times even large one orders of magnitude of film condensation.The condensation of steam in horizontal tube (or tube sheet), belongs to film condensation substantially.During film condensation, wall is always covered with by one deck liquid film, condenses to emit the heat of transformation (latent heat) and must just can pass on cooling wall through liquid film.Therefore, the main feature of film condensation, the thermal resistance that is exactly condensation heat transfer process almost all concentrates in condensate film.For film condensation, want to improve its coefficient of heat transfer, just necessary reducer film thickness, or turbulization film condensation heat transfer, the transmission of heat like this, except the laminar sublayer as thin as a wafer near wall still relies on heat-conducting mode, beyond laminar sublayer, take turbulent flow transmission as main, heat exchange efficiency is significantly increased.
Existing condenser is unresolved above-mentioned technical problem all, owing to generally can forming gas-liquid mixed phase in its exit collector, not only gas phase refluxes and hinders flowing of heat exchanging pipe inner fluid, and is unfavorable for reducer film thickness, therefore heat exchange efficiency is lower, and condensation effect can not be satisfactory.
Utility model content
Technical problem to be solved in the utility model is that the split type middle discharge opeing condenser system that a kind of coefficient of heat transfer and condensation efficiency are higher is provided.
For achieving the above object, the utility model has adopted following technical scheme.
In the middle of split type, discharge opeing condenser system, is characterized in that: it comprises backing condenser and rear class condenser, and described condenser comprises that lower end is provided with the casing of axial flow blower with air inlet, upper end; Heat exchanger is installed in casing, and the heat exchanger tube front end of heat exchanger is connected with upstream end collector, and rear end is connected with exit collector; The exit collector of backing condenser is connected with the upstream end collector of rear class condenser, introduces the heat exchanger of rear class condenser for the gas that backing condenser is discharged; Discharging tube in the middle of the exit collector of backing condenser is also connected with.
Described condenser also comprises the water leg that is positioned at casing below, the shower that connects the water pump of water leg and be arranged on heat exchanger top in casing; Filler between axial flow blower and shower is also installed in casing.
Exit collector is connected with fluid-tight.
Can also comprise auxiliary condenser; The exit collector of afterbody condenser connects reservoir, and reservoir is connected with described auxiliary condenser by escape pipe.
The utlity model has following characteristics.
The utility model has been implemented middle discharge opeing at prime heat exchanger end, and prime exit collector is connected with rear class upstream end collector by pipeline, the gas that prime heat exchanger is discharged is introduced in rear class heat exchanger, be conducive to flowing of heat exchanging pipe inner fluid, and accelerated the discharge of liquid film in heat exchanging pipe.Accelerate the discharge of liquid film, be equivalent to reducer film thickness even liquid film taken away wall, locally produce similar dropwise condensation effect, thereby make the coefficient of heat transfer significantly increase.Owing to having increased the steam flow velocity of suitable liquid film flow direction, can make liquid film turbulization, also can make on the other hand liquid film by the wall that blows off, thereby the coefficient of heat transfer is increased.
Middle discharge opeing can effectively improve the utilization rate of heat exchanger heat-transfer surface, and therefore structure of the present utility model can guarantee that prime heat exchanger is all the time in high efficient heat exchanging state.
Accompanying drawing explanation
Fig. 1 is structure of the present utility model and operation principle schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
Embodiment mono-
The present embodiment is a kind of air cooled condenser.
As shown in Figure 1, embodiment of the present utility model comprises two backing condenser I and a rear class condenser II.Backing condenser I and rear class condenser II all have following structure: condenser comprises that lower end is provided with the casing 1 of axial flow blower 11 with air inlet 7, upper end.Heat exchanger 3 is installed in casing 1, and the heat exchanger tube front end of heat exchanger 3 is connected with upstream end collector 2, and rear end is connected with exit collector 9.Under axial flow blower 11 effects, cold wind enters in casing 1 and the heat exchanger 3 of flowing through from air inlet 7, carries out from casing 1 upper end, discharging after heat exchange with the heat exchanger tube inner fluid of heat exchanger 3.
The exit collector 9 of two backing condenser I is connected with the upstream end collector 2 of rear class condenser II by gas piping 12, introduces the heat exchanger 3 of rear class condenser II for the gas that two backing condenser I are discharged.
The exit collector 9 of the middle discharging tube that the exit collector 9 of backing condenser I connects and rear class condenser II can be connected with respectively fluid-tight 8, and fluid-tight 8 connects reservoir by total discharging tube 13.
Wherein the exit collector 9 of afterbody condenser also can directly connect reservoir, now, auxiliary condenser need be set, and reservoir is provided with escape pipe and the liquid back pipe being connected with auxiliary condenser respectively.Gas in reservoir is back to reservoir after auxiliary condenser condensation liquefaction.Reservoir also can only be provided with the escape pipe being connected with auxiliary condenser, and the gas in reservoir flows to other reservoir after auxiliary condenser condensation liquefaction.
Embodiment bis-
The present embodiment is a kind of evaporative condenser.
Still as Fig. 1, on the basis of embodiment mono-, the condenser of the present embodiment also comprises the water leg 6 that is positioned at casing 1 below, the shower 10 that connects the water pump 5 of water leg 6 and be arranged on the interior heat exchanger of casing 1 top, and wherein water pump 5 is connected with shower 10 by upper hose 4.Filler between axial flow blower 11 and shower 10 is also installed in casing 1.
