[0005] Technical solution: The utility model is an acid waste gas spray channel structure, which is characterized by comprising two acid gas spray channel tubes, the upper acid gas spray channel tube is truncated cone-shaped, and the lower acid gas spray channel tube is inverted truncated cone-shaped, and the two acid gas spray channel tubes are connected by bolts passing through flange holes of corresponding flanges; the side wall of the acid gas spray channel tube is a hollow structure, the outer tube wall of the side wall is provided with a water inlet, and the inner tube wall of the side wall is provided with a plurality of water outlet holes.

[0006] Wherein, the above acid gas spray channel tube is connected to the external channel pipe through a flange.

[0007] Wherein, the acid gas spray channel tube below is connected to the external channel pipe through a flange.

[0008] Wherein, a sealing rubber ring is provided between the two acid gas spray channel tubes.

[0009] Wherein, the flange is provided with a plurality of flange holes.

[0010] Wherein, the bolt passes through the flange hole of the corresponding flange and is movably connected with the nut through the corresponding thread.

[0011] Wherein, a gasket is arranged between the bolts, nuts and flanges.

[0012] Wherein, the water inlet is connected to an external water inlet pipe.

[0013] Beneficial effects: Compared with the prior art, the utility model has the following significant advantages: the utility model adopts a modular assembled structure to form a temporary storage space for acidic gas, centrally sprays the acidic gas in the space, improves the spraying efficiency, and effectively prevents the leakage of acidic gas to pollute the environment.
