The specific embodiment
As shown in Figure 1, the utility model is cylindric by upper mounting plate 1, heat-exchanging tube bundle 2, unequal distant screw deflector 3, form every tube 4 and lower installation board 5 on the whole.Heat-exchanging tube bundle 2 each pipe distribute with one heart to whole axis and are parallel to each other, and heat-exchanging tube bundle 2 central authorities have coaxial with it every tube 4, are connected with upper mounting plate 1 every tube 4 upper port, are connected with lower installation board 5 every tube 4 lower port; Be distributed with unequal distant screw deflector 3 every tube 4 outer walls along axis direction, each pipe in the heat-exchanging tube bundle 2 never equidistantly passes in the corresponding aperture of spiral deflector 3, the upper end of heat-exchanging tube bundle 2 each pipe is passed from upper mounting plate 1 corresponding aperture, the lower end of heat-exchanging tube bundle 2 each pipe is passed from lower installation board 5 corresponding apertures, and the outer wall of respectively managing in the heat-exchanging tube bundle 2 closely is connected with upper mounting plate 1, unequal distant screw deflector 3 and the hole wall contact position in lower installation board 5 corresponding each hole.
Shown in Figure 2, the utility model is used for the evaporative condenser heat-exchanger rig that seawater is made distilled water, and this installs by upper mounting plate 1, heat-exchanging tube bundle 2, unequal distant screw deflector 3, liquid distributor 10, lower accepting water dish 11 and distilled water storage pond 12 are formed in tube 4, lower installation board 5, booster fan 6, vapour hood 7, tube head liquid distributor 8, shell 9, pipe.Upper mounting plate 1, heat-exchanging tube bundle 2, unequal distant screw deflector 3, be cylindric on the whole every tube 4 and lower installation board 5.Heat-exchanging tube bundle 2 each pipe distribute with one heart to whole axis and are parallel to each other, and heat-exchanging tube bundle 2 central authorities have in parallel every tube 4, are connected with upper mounting plate 1 every tube 4 upper port, are connected with lower installation board 5 every tube 4 lower port; Be distributed with unequal distant screw deflector 3 every tube 4 outer walls along axis direction, each pipe in the heat-exchanging tube bundle 2 never equidistantly passes in the corresponding aperture of spiral deflector 3, the upper end of heat-exchanging tube bundle 2 each pipe is passed from upper mounting plate 1 corresponding aperture, the lower end of heat-exchanging tube bundle 2 each pipe is passed from lower installation board 5 corresponding apertures, and the outer wall of respectively managing in the heat-exchanging tube bundle 2 closely is connected with upper mounting plate 1, unequal distant screw deflector 3 and the hole wall contact position in lower installation board 5 corresponding each hole.Heat-exchanging tube bundle 2 each pipe are equipped with liquid distributor 10 in tube head liquid distributor 8 and the pipe.The inwall of the outer edge of unequal distant screw deflector 3 and shell 9 is close to.The bottom of vapour hood 7 closely is connected with the edge of upper mounting plate 1, forms a sea container, and sea container has an outlet to insert the fresh seawater of preheating; Booster fan 6 is housed in the upper opening of vapour hood 7, and the motor of booster fan 6 is contained in the top of shell 9; The edge of lower installation board 5 closely is connected with the upper edge edge of lower accepting water dish 11, and the bottom of lower accepting water dish 11 has an outlet to lead to outside the shell 9; Distilled water storage pond 12 is formed on the bottom that shell 9 is lower than lower accepting water dish 11, and an outlet is arranged at distilled water storage 12 tops, pond, and for discharging incoagulable gas, there is an outlet its underpart for output distilled water.
When the fresh seawater through preheating entered the sea container on evaporative condenser heat-exchanger rig top, booster fan 6 was taken out steam in the sea container outside vapour hood 7, the vapour hood 7 outer higher-pressure regions that form, and steam temperature in this zone raises.High-temperature steam enters unequal distant screw deflector 3 downwards from vapour hood 7 outsides along crust of the device 9 inboards under pressure, along unequal distant screw deflector 3 and heat-exchanging tube bundle 2 heat exchange.High-temperature steam is condensed into liquid gradually in heat transfer process, and volume diminishes gradually, becomes the close unequal distant screw deflector high-temperature steam guiding outer casing underpart with remainder gradually, until all being condensed into distilled water; The residue incoagulable gas is drained from the outlet on distilled water storage 12 tops, pond.In heat transfer process, the pre-hot sea waters in the heat-exchanging tube bundle 2 flow in the pipe along tube head liquid distributor 8 (see figure 3)s, form the high temperature liquid film in tube wall, and the high temperature liquid film absorbs in heat exchange in the lower accepting water dish 11 that heat evaporates, thickens, flows to tube bank rapidly.For the more even distribution of liquid film in the heat-exchanging tube bundle 2 is evaporated easily, in heat-exchanging tube bundle 2, be provided with liquid distributor 10 (see figure 4)s in the pipe again.Steam in the heat-exchanging tube bundle 2 rises in the vapour hood 7, under the swabbing action of booster fan 6, flow to outside the vapour hood 7, pressure and temperature raises, enter next round heat exchange circulation ..., so go round and begin again, the fresh seawater of preheating constantly is evaporated concentrated, and concentrated seawater is discharged through the outlet of lower accepting water dish 11 bottoms; The distilled water that outer casing bottom stockpiles is discharged through distilled water outlet.
Shown in Figure 5, the utility model laterally is installed in the conventional heat exchanger shell 9, begins the unequal distant screw deflector 3 that pitch diminishes gradually from import and closely contacts with the inwall of heat exchanger shell 9.It has aperture by housing 9 horizontal bottom places, passes through for condensed water.When high-temperature steam can only flow to outlet along unequal distant screw deflector 3 when import enters, carry out heat exchange with cryogenic liquid or cryogenic gas in the heat-exchanging tube bundle 2.Because high-temperature steam in heat exchange, is condensed into liquid gradually, volume reduces gradually, therefore, does not wait the pitch of spiral deflector just can reduce gradually, makes the compact conformation of heat exchanger.Be applicable to the heat exchanger of condensing process.
Owing in the middle of the heat-exchanging tube bundle 2 of the pipe bundle heat exchanger of routine, be provided with a unequal distant screw shape deflector 3, traditional deflection plate 13 (see figure 6)s have been replaced, when liquid stream in suitable unequal distant screw deflector 3 of heat exchange steam and the heat-exchanging tube bundle 2 or air-flow generation heat exchange, distance increases, time increases, and there is not the heat exchange dead band, thus the utility model heat exchange efficiency height, compact conformation.
The utility model is applicable to the heat exchange between the two media, and this two media can be gas-steam, liquid-steam.
