Abstract
The utility model provides a closed type cooling tower coil pipe which relates to a condensing facility. The geometric shape of the cross section of the coil pipe is improved, and a positive circular shape is changed into a water drop shape. A rotational flow device is additionally arranged in the coil pipe, and a plurality of reed-shaped spiral sheets are arranged at an inlet of the coil pipe and the butt welding position in the middle of the coil pipe. The utility model changes the cross sectional shape of the coil pipe and reduces the resistance force for the rising of wet hot air, and simultaneously, the rotational flow device is additionally arranged at an inlet in the coil pipe to ensure that media can generate turbulent flows, so that the problem of low heat radiating efficiency of the cooling tower coil pipe because of the influence of the temperature gradient is overcome.
Description
Technical field
The utility model relates to a kind of condensation facility.
Background technology
In the heat transfer technology field, be that heat exchanger or condenser all are to pass to outside the coil pipe by the heat of coil pipe with medium in it.In recent years, people sprayed a large amount of water by a kind of device, had water that coil pipe is surrounded all the time, and it is perfect that its outer moisture film is grown, and has enough air mass flows to skim over the coil pipe moisture film simultaneously, impels water film evaporation, and then damp-heat air is discharged to outside the tower by the cat head blower fan.
Current, there are two problems in the core apparatus " coil pipe " of enclosed (dual-cooling type) cooling tower, and the one, the coil pipe cross-sectional geometry is rounded, and the gas-flow resistance of skimming over coil pipe damp-heat from bottom to top increases, can reduce air quantity, unfavorable to diffusing matter, the heat radiation of shower water.The 2nd, the medium turbulent extent in the coil pipe is poor, and medium has one " velocity gradient " along the section radius within it, and the tube hub flow velocity is big, and tube wall place flow velocity is little.The medium particle movement direction overwhelming majority is vertically, and is considerably less along the particle that radius moves, " thermograde " that is produced, i.e. and the temperature of medium, the height of tube hub, the temperature of tube wall is low.The heat radiation that this is unfavorable for coil pipe makes whole cooling tower coefficient of heat transfer low very much, and radiating efficiency is poor.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of novel cooling tower coil pipe, it is unreasonable to solve existing coil pipe cross-sectional configuration shape, and gas-flow resistance is big and the interior medium turbulent extent of pipe is poor, and the low problem of the radiating efficiency that causes because of velocity gradient.
The technical scheme that its technical problem that solves the utility model adopts is: the geometry of improving the coil pipe cross section, change water droplet shape structure into by positive circle, set up swirl-flow devices in the coil pipe, some tongue shape flights are arranged at coil pipe inlet and middle butt welding place of coil pipe.
Adopt good effect of the present utility model to be: by changing the coil pipe cross sectional shape, reduced the resistance that damp-heat air rises, swirl-flow devices is set up in the porch in the coil pipe simultaneously, makes the medium turbulization, has overcome the low problem of cooling tower coil pipe radiating efficiency that causes because of " thermograde " influence.
Description of drawings
The contrast drawings and Examples further specify the utility model below:
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model A-A sectional views.
Accompanying drawing 3 is that the utility model B is to view.
1 coil pipe, 2 delivery ports, 3 water inlets, 4 flights among the figure.
Concrete real-time mode
As shown in the figure; Coil pipe 1 adopts stainless steel tube machine-shaping in mould, its water inlet (2) all is processed into drops with the coil pipe cross section, flight (3) is the tongue shape, be installed in middle butt welding place of coil pipe inlet and coil pipe, it can change the medium fluidised form into turbulent flow, increases the medium particle along the ratio that the tube wall radial direction moves, and makes " thermograde " gentle, and then increase the coil pipe heat transfer coefficient, improve the cooling tower radiating efficiency.
Claims (1)
1, a kind of closed cooling tower coil pipe is made up of coil pipe, water inlet, flight, it is characterized in that: the coil pipe cross section is a water droplet shape structure, establishes swirl-flow devices in the coil pipe, and some tongue shape flights are arranged at coil pipe inlet and middle butt welding place of coil pipe.
