Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

The embodiment of the utility model provides an including retort 1, ozone generator 2, conveyer pipe 3, motor 4, first gear 5, second gear 6, outlet duct 7, separation blade 9, one-way shower nozzle 10, outlet pipe 11, ozone destructor 12, transition pipe 13, force (forcing) pump 14, carousel 15 and rotary joint 16.

The top of the reaction tank 1 is provided with an ozone outlet, and an ozone destructor 12 is installed at the ozone outlet.

The rotary table 15 is rotatably installed on the bottom plate of the reaction tank 1, and a sealing structure is arranged between the rotary table 15 and the bottom plate of the reaction tank 1 to prevent water leakage, and the sealing structure can be a sealing ring and other prior art.

The transition pipe 13 is located inside the reaction tank 1 and is fixed on top of the rotating disk 15.

The air outlet pipe 7 is vertically arranged in the reaction tank 1, and the bottom of the air outlet pipe is fixed and communicated with the transition pipe 13. The two sides of the air outlet pipe 7 are symmetrically and fixedly provided with baffle plates 9. A plurality of groups of mutually matched one-way nozzles 10 are uniformly arranged on the air outlet pipe 7. In this embodiment, four outlet pipes 7 are provided.
