Hereinafter, the configuration of the present invention with reference to the drawings in detail.

FIG. 2 is a cross-sectional view showing a noxious gas exhaust device of the tank according to the present invention, FIG. 3 is an enlarged cross-sectional view showing main parts of the exhaust device of FIG. 2, and FIG. 4 is an enlarged cross-sectional view of FIG.

2 to 4, the tank having a noxious gas exhaust device according to the present invention is divided so as to communicate with each other by a plurality of partitions 112 installed therein, the inlet pipe 132 in the upper and lower parts And the discharge pipe 134 is in communication. In this case, the material of the tank is preferably cast iron, stainless steel, other metal materials and may also be made of cement cement.

The first exhaust means 150 of the present invention is a first installed in the tank so as to communicate with the inlet pipe 132 to automatically discharge the harmful gas such as chlorine gas in the tank by the inlet pressure or the outlet pressure of the liquid It is provided in the connecting pipe (162).

The first exhaust means 150 may include a first rotating member 152 disposed in the inlet pipe 132, one end connected to the first rotating member 152, a first link member 154, and a first link member ( The exhaust fan 156 is connected to the other end of 154.
