The upper end surface of the rectangular thin plate is a conical surface.

The thickness of the rectangular thin plate is 7-9 mm.

Due to the adoption of the technical scheme, the utility model discloses following beneficial effect has:

1. compressed air enters a cavity at the upper part of the high-efficiency gas-water mixer in a tangent mode, gas continuously rotates in the mixer under certain pressure and moves downwards in a rotating mode, so that the retention time of the gas in the mixer is prolonged, namely, the time for the gas to be fully contacted with liquid is prolonged, and the mixed substances are more fully dissolved.

2. The mixing vibrator is additionally arranged at the lower part of the high-efficiency gas-water mixer, crude brine is sprayed out from the nozzle and then falls onto the mixing vibrator, and the mixing vibrator vibrates, so that the crude brine is vibrated and splashed in sequence, the crude brine and the rotating gas are mixed and dissolved, the effect of fully mixing and dissolving gas and liquid is achieved, and the high-efficiency gas-water mixer has positive significance for process production and energy consumption cost reduction.

3. The structure is simple. Compare with original blender, the utility model discloses only increased a simple and easy mixed vibrator, modified into tangential direction with the salt solution import pipe simultaneously and get into, structural improvement is little, but has obtained the mixed effect of ideal, has greatly improved the utilization efficiency of back process, reduces the running cost.

The technical features of the efficient gas-water mixer for caustic soda production according to the present invention will be further described with reference to the accompanying drawings and examples.
