Abstract
The utility model relates to a natural draft's steel construction tower body, including tower body main structure (1), beaded finish (2) and covering (3), tower body main structure (1) and beaded finish (2) is the steel construction, is tower body main structure (1) including upper portion cylindrical portion (1 1 )With lower part round platform part (1 2 ), its characterized in that: upper portion cylindrical portion (1 in tower body main structure (1) 1 )Outer wall set up beaded finish (2), internal face in tower body main structure (1) adheres to covering (3). The utility model discloses covering gaseous in with the tower with the non -corrosibility can be good is kept apart with the tower body main structure, has avoided gaseous corruption to tower body main structure and beaded finish in the tower, is applicable to indirect air cooling project that the cigarette tower unifies and open water cooling tower project.
Description
Technical field
This utility model relates to the steel construction tower body of a kind of gravity-flow ventilation, for thermal power plant cooling system or similar circulating water cooling system.
Background technology
During thermal power generation, the indirect air cooling system as one of major air cooling system is widely used the most.Indirect air cooling system uses the form of gravity-flow ventilation, needs to build the highest cooling column body.Use or be substantially xoncrete structure at the cooling column body built at present, but, due to the advantage that steel construction tower body has low cost, the construction period is short and anti-seismic performance is good, the most occur that the steel construction tower body of minority is being built or design.The mainstream technology scheme of steel construction tower body is such that tower body main structure and uses welded steel structure, the profile of tower body main structure is upper cylindrical, bottom truncated cone-shaped, the horizontal reinforcing ring of multiple tracks it is provided with to strengthen the rigidity of tower body in upper cylindrical, the eyelid covering of upper and lower tower body outside wall surface (tower body main structure outer wall) attachment aluminum matter, eyelid covering seals.Some indirect air cooling project, in order to save the investment of chimney, chimney is arranged in inside tower body, the height utilizing tower body is discharged smoke evacuation together with hot-air in tower, this tower is also referred to as the indirect dry cooling tower of nicotinic acids, so, tower body main structure (steel construction) and reinforcing ring can be caused additional corrosion by the smoke evacuation of tower inner chimney.
This eyelid covering is outer at tower, tower body main structure and reinforcing ring version Shortcomings in tower: for the air cooling tower of nicotinic acids, affected by smoke evacuation in tower, tower body main structure and reinforcing ring part have to improve requirement for anticorrosion, processing and tower body to steel beam column are installed and are caused difficulty, also improve the construction cost of tower body.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned gravity-flow ventilation steel construction tower body, it is provided that a kind of anticorrosion more preferably, process and be easily installed, the steel construction tower body design technology project of lower-cost gravity-flow ventilation.
The purpose of this utility model is achieved in that the steel construction tower body of a kind of gravity-flow ventilation, including tower body main structure, reinforcing ring and eyelid covering, tower body main structure and reinforcing ring are steel constructions, tower body main structure includes Upper cylindrical section and bottom round platform part, is characterized in: the outside wall surface at the Upper cylindrical section of tower body main structure arranges reinforcing ring；Internal face in tower body main structure adheres to eyelid covering.
The steel construction tower body of a kind of gravity-flow ventilation of this utility model, described eyelid covering is made up of aluminium sheet or bending failure.
The steel construction tower body of a kind of gravity-flow ventilation of this utility model, described reinforcing ring is horizontally disposed with, and quantity is multiple tracks.
The steel construction tower body of a kind of gravity-flow ventilation of this utility model, the attachment area of described eyelid covering contains whole internal faces and the internal partial wall face of bottom round platform part of Upper cylindrical section.
The steel construction tower body of a kind of gravity-flow ventilation of this utility model, major advantage is: tower body main structure and reinforcing ring are had corrosive gas (such as flue gas, damp atmosphere etc.) isolation in tower by the eyelid covering good with antiseptic property, in avoiding tower, gas is on tower body main structure and the impact of the steel beam column of reinforcing ring, also reduces the requirement for anticorrosion to tower body main structure and reinforcing ring.This utility model is applicable not only to the indirect dry cooling tower of nicotinic acids, it is also possible to be applied to the water cooling tower (shower water wet cooling tower in common tower) of open type.
Accompanying drawing explanation
Fig. 1 is this utility model embodiment 1 schematic diagram.
In figure:
Tower body main structure 1
Upper cylindrical section 1-1
Bottom round platform part 1-2
Reinforcing ring 2
Eyelid covering 3.
Detailed description of the invention:
Seeing Fig. 1, this utility model embodiment 1 is the steel construction tower body of a kind of gravity-flow ventilation, is made up of tower body main structure 1, reinforcing ring 2 and eyelid covering 3.Tower body main structure 1 and reinforcing ring 2 are steel welding structures, and tower body main structure 1 includes Upper cylindrical section 1-1 and bottom round platform part 1-2.Outside wall surface at Upper cylindrical section 1-1 is horizontally arranged reinforcing ring 2, from figure 1 it appears that this example has 5 road reinforcing rings 2.The quantity of reinforcing ring 2 is determined according to load calculating by designer.Internal face in tower body main structure 1 adheres to (has installed) eyelid covering 3, and eyelid covering 3 seals, and it seals position and includes whole internal faces and the internal partial wall face of bottom round platform part 1-2 of Upper cylindrical section 1-1.Eyelid covering 3 is made up of the preferable aluminium sheet of antiseptic property, it is also possible to select bending failure to make.
Claims (4)
1. the steel construction tower body of a gravity-flow ventilation, including tower body main structure (1), reinforcing ring (2) and eyelid covering (3), tower body main structure (1) and reinforcing ring (2) are steel constructions, tower body main structure (1) includes Upper cylindrical section (1-1) and bottom round platform part (1-2), it is characterised in that: the outside wall surface at the Upper cylindrical section (1-1) of tower body main structure (1) arranges reinforcing ring (2)；Internal face in tower body main structure (1) adheres to eyelid covering (3).
The steel construction tower body of a kind of gravity-flow ventilation the most according to claim 1, it is characterised in that: described eyelid covering (3) is made up of aluminium sheet or bending failure.
