When doing the analysis of acidic water stripping, the acidic water tank broke through the safety water seal when it was overpressured and directly discharged to the atmosphere. Since it is hydrogen sulfide gas, it is very toxic. I don’t know if there is a closed discharge design. I would like to ask for advice. How to solve the negative pressure problem with closed discharge?

Under normal circumstances, the atmosphere is exhausted through the deodorization tank, but under abnormal circumstances, it will directly break through the safety water seal and exhaust the atmosphere. I am asking about this situation. After all, direct exhaust of hydrogen sulfide will cause harm, but where should it be exhausted? It’s a question. Maybe everyone agrees that in this situation, there is no way and it is a risk that must be taken, right?
The last odor treatment is to absorb the emulsion of sodium hypochlorite and sodium hydroxide.
Generally, there is an adsorption tank (containing adsorbent) after the water-sealed tank is exhausted.
