How to improve the negative pressure deformation of fermentation tanks
Thread Content
There is a 5,000 m3 fermentation tank at the project site; due to heavy rain the day before, the top of the tank became unstable and deformed, resulting in cracks. The original fermenter was equipped with a breather valve for protection, but it failed to provide any protection. How can the protective measures be improved? Should the size of the safety valve be increased?
You can add a water seal groove; it’s simple and practical
There is a water seal tank between the exhaust pipe of the fermentation tank and the desulfurization system; since the fermentation tank has just been filled with material and no gas has been produced yet, the exhaust valve is temporarily closed to prevent the systems from being connected in series. Would adding another water seal be unnecessary? Does the original breathing valve need to be removed and sealed?
The breathing valve is fine according to its design, but it won’t work if there are debris stuck in it or if it gets damaged； The water seal is connected to the atmosphere
Should the water seal be added directly at the exhaust port of the pouring ceremony, or should it be led to the ground first before the water seal is added?

Okay, thank you. If it is to be linked to the main website, the site needs to be restructured; we’ll decide on this after discussing it with the client.
Could you explain to me why a closed fermentation tank becomes unstable?
It wasn’t properly managed on a daily basis! Treat each specific problem individually!
