By design, I don’t mean simple strength calculations; it mainly refers to the fluid dynamics aspect, namely the design of the inlet distributor! Is there a case where that was done and driving was involved?
Imported distributors are designed based on the properties of the materials, so they have no versatility! Many distributors are also continuously refined through testing; we have used many of them, and even to this day, we have not found the perfect one!
Did the person upstairs mean twisted iron? Similar to the nozzles used for desulfurization, but with a different working principle. Film evaporation is used for liquids with high viscosity and high boiling points ； :D
There are various types of distributors for tubular falling film evaporators, with design principles including uniform film distribution, resistance to clogging, and ease of cleaning.
We have manufactured falling-film flash evaporators designed by a design company in Wuhan; they are the company’s patented products, and the equipment is in use with satisfactory results
Everyone is talking about the principles, but what’s the use if they don’t go into more detail?
The distributor should be designed according to the type of medium.
Due to differences in material properties, there are significant variations among distributors. No standard
The original poster isn’t clear in their explanation. As you said, everything designed by each designer has a basis; if there’s no such basis, it means the company doesn’t pay attention to quality and its brand. There are standards for all these things; you can refer to those standards
Why don’t you check Yixing Grant? This company is said to be very strong
Sulzer, a company founded by Chinese people in Switzerland, is not very large, but it is renowned worldwide for its design and manufacturing capabilities in this field; it has branches in Shanghai and Dalian in China. A typical example of a falling film evaporator that I have seen is the hydrogen peroxide concentration unit; it offers great operational flexibility and is easy to adjust.
