Manufacturing of plate towers with tower diameter 200mm
Thread Content
Can a plate tower with a tower diameter of 200mm be manufactured using flange connections? There are 10 tower plates and the plate spacing is 400mm. Does anyone have experience in using stainless steel?
It can be made into a whole type, that is, string type.
How to make such a small tray? Use packing tarot.
The diameter of the tower is so small, so it’s better to use packing.
The tower diameter is too small. If there are too few sections, there will be problems with the tray installation. If there are too many sections, there will be more equipment flanges, which will increase the equipment cost and increase the equipment leakage points.； How to support it? If the skirt is self-supporting, it is slightly better. If it is supported by the ear seat, the support point is at the bottom of the tower, and the installation requirements of the tower are higher. It is best to use a packed tower.
It's possible, but I don't think it makes any sense. It is an unconventional tower equipment. It cannot simply be designed according to the design standards of the tower internals.
There should be no reason why it would be inappropriate to make a random packing tower rather than a plate tower.
Why can't it be designed according to the design standards of tower internals? If the inner diameter of the tower designed according to the design standards of tower internals is 200mm, is there any problem with this?
Yes, the cylinder body is made of steel pipe. Diameter is 219
Although I don’t know much about tower design, according to the information I searched, the manufacturer seems to have given me that the tower diameter can range from Φ200-Φ1500. When the tower diameter is small, the packed tower is cheap because of its simple structure. The diameter of the packed tower can be very small. The diameter of the plate tower is generally not less than 0.6m. This post was last edited by Chuangxin Packing on 2009-4-10 15:58 ]
The smallest diameter plate tower we have ever made is DN500. As the poster said, it is so small that only packing or flange sections can be used. Every two tower plates are one section.
Towers with such a small diameter are really rare. Generally, plate towers with such a small diameter are only used in laboratories. In industrial production, towers with such a small diameter are generally packed towers. For distillation towers with small diameters, the separation efficiency of packed towers is higher than that of plate towers. I wonder if the author designed such a tower to be used in laboratories or industrial production?
If it must be made into a plate tower, I think it should be a tower section of 800mm, and each tower section should be equipped with 2 trays at an interval of 400mm, so it should be able to be installed.
It's actually a small trial device, but I don't know if it can be produced.
To do this, use 400-section pipes, a total of 11 sections, one end of each section is made into a tray, and the last section and the top section are made into flexible ones, so that they can be easily disassembled. Two adjacent sections are connected with flanges. I don’t know if I made it clear.
1. The "tower" you refer to does not fall within the design scope of "Technical Regulations on Tower Design" HG20652-1998； 2. It does not fall within the design scope of "Petrochemical Tray Design Specification" SH3088-1998, because it is divided into blocks. Yours is so small that there is no need to divide it into blocks. ； 3. The specifications of the standard parts used such as clamps and connectors are too large. They are matched with the segmented trays, so you cannot use them. Secondly, the specifications of the standard F1 float valve and other guided float valves derived from it are too large. The diameter of the F1 float valve is 39mm, which is not suitable for you. 4. In conventional design, the width of the downcomer is 10% of the tower diameter, so your downcomer is only 2 cm, so it cannot be used. Wait, there are a lot of factors why you can't use a plate tower. Moreover, if you have to use a plate tower, you can only increase the diameter, and use a micro float valve or a sieve plate tower. It is recommended to use packed tower.
The minimum effective flow length of a plate tower is usually more than 400MM. It makes no sense to use trays for such a small tower, even for experiments.
