Regarding the drying device on the top of the sulfuric acid tank
Thread Content
Earlier, I saw that a member in our forum raised the issue of drying at the air inlet on the top of storage tanks. Such an inlet must indeed be installed, as every storage tank should have air inlets and outlets to balance pressure. As far as I know, a small drying device is usually installed at the top to use concentrated sulfuric acid to dry the air entering the storage tank; otherwise, corrosion on the top of the tank becomes quite severe. But I’ve never understood how to set up that drying device? How to design? I wonder if any colleagues have similar drawings or experience they could share. I will also ask for advice from my friends at the sulfuric acid plant, and I’ll share the results with everyone for discussion! Those who are familiar with the drying and regeneration methods for desiccants can also discuss them in detail! This post was last edited by gongzhihai on 2007-12-3 23:18]
In my opinion, a silicone dryer can be designed with hot air recirculation for regeneration; this can be controlled using a time relay and solenoid valve, and the technology involved is not complex. The advantage of the aforementioned dryer is that it eliminates the need for concentrated acid pipes and valves for upper and lower storage tanks, making maintenance simple as well.
I think it’s easy to create a silica gel dryer, but it’s difficult to implement hot air. I’m currently facing exactly this problem: I can design a silica gel dryer, but I don’t have hot air – I don’t know how to solve that
