Change the design of the internals in the saturated hot water tower
Thread Content
Recently, I am planning to build a saturated tower; originally, a random-packed packing design was intended to be used. There are also structured packing and vertical sieve plates, etc. I wonder which type is being used by everyone, and what the performance is like?
It turns out we were using a bulk packing format. Magnetic ring (saddle ring).
The sieve plate design used in our saturated hot water towers works quite well. If it is to be manufactured, there are specially designed tray formats that can be used directly, and then the cylinder can be produced.
Our company’s saturated hot water tower: Ø2600×26610, made of 0Cr18Ni9 material. Operating pressure: 2.1 MPa; operating temperature: 40–185°C. Design pressure: 2.2 MPa; design temperature: 185°C. It is equipped with 2 sets of vertical sieve plate assemblies – 15 plates in the saturated section and 17 plates in the hot water section. The operating media are semi-water gas, shift gas, and water. Last edited by wulashan on 2009-2-17 at 17:40
We use stainless steel Pall ring random packing, and the resistance is relatively low. However, once a pipe in the system burst, it pulled out all the packing from the hot water tower, blocking the pipes and causing a second shutdown (the outlet plug came off). It is recommended to use structured materials instead.
