Abstract
The utility model is a kind of evaporative condenser, and the outside side of casing is provided with water outlet collector and this side air inlet cover at inner auxiliary wind box, and auxiliary wind box is also with auxiliary air inlet; Water outlet collector is between this side air inlet and auxiliary air inlet.Cold wind by axial flow blower guiding carries out time condensation to the liquid-vapor mixture in water outlet collector, effectively reduce the ratio of steam in liquid-vapor mixture, thereby reduce vapour heat exchange pipe end gas pressure, heat exchanger tube inner fluid positive movement speed is accelerated, and accelerate the discharge of moisture film in heat exchange pipe, attenuate water film thickness even moisture film taken away pipeline wall, local produce similar dropwise condensation effect; Owing to having increased the steam flow rate of suitable liquid film flow direction, can make moisture film turbulization simultaneously, thereby the coefficient of heat transfer is increased.Therefore the utlity model has higher heat exchange efficiency and condensation efficiency.
Description
Technical field
The utility model relates to a kind of steam condensing device.
Technical background
Existing evaporative condenser, owing to accumulating the liquid-vapor mixture that has some on heat exchange pipe end tube wall, forms " moisture film ", the heat exchange in the impact outer cold wind of pipe and current and pipe between high-temperature medium, and hinder tube fluid motion; Based on same reason, flow in the liquid-vapor mixture draining collector steam ratio from heat exchange pipe end too high, these steam are isolated by the page in fluid-tight case, after pressure acquires a certain degree, return to heat exchange pipe through draindown header, further hinder tube fluid positive movement.Therefore condensation effect is not good enough.
Utility model content
Technical problem to be solved in the utility model is that the evaporative condenser that a kind of heat exchange efficiency and condensation efficiency are higher is provided.
For achieving the above object, the utility model has adopted following technical scheme.
Evaporative condenser, it is characterized in that: comprise lower end not ipsilateral be respectively arranged with air inlet, upper end is provided with the casing of axial flow blower, heat exchange pipe is installed in casing, the front end of heat exchange pipe is connected with admission collector, rear end is connected with the water outlet collector that is positioned at the outside side of casing, water outlet collector is connected with fluid-tight case by pipeline, also comprise the spray header that is arranged in casing and is positioned at heat exchange pipe top, it is characterized in that: the outside side of casing is provided with water outlet collector and this side air inlet cover at inner auxiliary wind box, auxiliary wind box is also with auxiliary air inlet, described water outlet collector is between this side air inlet and auxiliary air inlet.
Pipeline between water outlet collector and fluid-tight case passes from auxiliary air inlet.
The utlity model has following characteristics.
Cold wind by axial flow blower guiding carries out time condensation to the liquid-vapor mixture in water outlet collector, effectively reduce the ratio of steam in liquid-vapor mixture, thereby reduce vapour heat exchange pipe end gas pressure, heat exchanger tube inner fluid positive movement speed is accelerated, and accelerate the discharge of moisture film in heat exchange pipe, attenuate water film thickness even moisture film taken away pipeline wall, local produce similar dropwise condensation effect; Owing to having increased the steam flow rate of suitable liquid film flow direction, can make moisture film turbulization simultaneously, thereby the coefficient of heat transfer is increased.Therefore the utlity model has higher heat exchange efficiency and condensation efficiency.
Brief description of the drawings
Fig. 1 is structure of the present utility model and operation principle schematic diagram.
Detailed description of the invention
Further illustrate the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, embodiment of the present utility model comprises lower end several are provided with the casing 1 of axial flow blower 14 with air inlet 7, upper end.Heat exchange pipe 2 is installed in casing 1, and the front end of heat exchange pipe 2 is connected with admission collector 11, and rear end is connected with the water outlet collector 8 that is positioned at the outside side of casing 1.Water outlet collector 8 is connected with fluid-tight case 10 by pipeline, and fluid-tight case 10 connects reservoir.Embodiment of the present utility model also comprises the water leg 5 that is positioned at casing 1 below, connects the water pump 4 of water leg 5 and is arranged on the shower 12 of the interior heat exchanger of casing 1 top, and wherein water pump 4 is connected with shower 12 by upper hose 3.Dash filler 13 between axial flow blower 14 and shower 12 is also installed in casing 1.
Special feature of the present utility model is: the outside side of casing 1 is provided with water outlet collector 8 and this side air inlet 7 are covered on to inner auxiliary wind box 6, and auxiliary wind box 6 is also with auxiliary air inlet 9.Described water outlet collector 8, between this side air inlet 7 and auxiliary air inlet 9, enters cold wind the auxiliary wind box 6 water outlet collector 8 of first flowing through from auxiliary air inlet 9 and then enters casing 1 through this side air inlet 7 around.Pipeline between water outlet collector 8 and fluid-tight case 10 passes from auxiliary air inlet 9.
When work, high-temperature steam enters heat exchange pipe 2 from admission collector 11, enters water outlet collector 8 after being condensed, and the liquid-vapor mixture in water outlet collector 8 enters fluid-tight case 10 after by the further condensation of cold wind, and last water is discharged to reservoir.
Under axial flow blower 14 sucking actions, cold wind enters in casing 1 and flows heat exchange pipe 2 outer walls, carries out discharging from casing 1 upper end after heat exchange with heat exchange pipe 2 inner fluids; The water spraying from shower 12 drenches at heat exchange pipe 2 outer walls, carries out falling in water leg 5 and recycling after heat exchange with heat exchange pipe 2 inner fluids.
