Circle and Square
Thread Content
Many of the equipment used in the chemical industry are cylindrical in shape; recently, I’ve seen cooling towers that have a square structure. It looks good; the square shape makes it convenient for transportation and on-site assembly, and its square structure saves space, as there is no need for all that unnecessary space around the cylinder. Containers require a structure that can withstand internal pressure, and generally, they are cylindrical in shape. On the one hand, rolling sheet metal requires only one weld; on the other hand, the sides of a cylindrical structure are subjected to uniform internal pressure, which makes the construction much simpler. The hyperbolic cooling towers in power plants have a very impressive appearance. High heat dissipation efficiency with low water splash loss
This type of cooling tower is widely used in small and medium-sized chemical enterprises
The threshold for entering this field is not high; once one company produces it, other companies can quickly replicate it. Intellectual property protection is inadequate in low-end industries
To facilitate installation in pipe racks, the air coolers are also square in shape
Cooling towers are common in chemical plants; the material used appears to be fiberglass
You are indeed well-informed. I have been with this company for ten years, and the equipment available in the fine chemicals industry is far inferior to that in the bulk chemicals industry
Petroleum projects are all arranged in this connected manner
Square water cooling towers are more commonly used these days. This involves issues such as efficiency, installation location, noise, and so on. The prices are actually pretty much the same. For circular water cooling, counterflow is generally used; it’s better to keep the area around it as empty as possible for better results. But backflow inevitably leads to increasingly lower efficiency. Square in shape, allowing for multiple options such as cross-flow or counter-flow; it can be connected in a modular manner, and its design can also be adjusted to be taller and more slender depending on the specific site conditions. Compared to counterflow, cross-flow generates much less noise and maintains higher efficiency. As for hyperbolas, the main consideration is also related to construction; their Gaussian curvature is remarkable – they hardly deform at all. Although they appear to be curved in shape, straight rebar can be used, which results in a thinner wall thickness, saving a large amount of material while still providing strong resistance to wind loads.
The middle part is thin while the upper and lower parts are thick, similar to a Venturi structure I guess. A gradually thicker upper section helps to reduce water loss due to splashing, right? The curve is quite interesting; the structure of Guangzhou’s Little Swallow Tail likely has similar characteristics
That’s right; the inward curve in the middle is the venturi, which increases the flow rate, acting as an additional effect. Of course, some literature also suggests that this is doubtful; theoretically, at such a height, even without this curve, the self-priming ventilation force would be sufficient to increase the flow rate. The slender waist has this structure, with spatially parallel diagonal lines serving as the main beams.
I had doubts, but they were just simple doubts. For example, with dust present, theoretically, at that height, even without such curves, the natural convection force would be sufficient to increase the flow rate.
