because the first jet refraction surface 64 on the first jet refraction disperser 1.1 and the second jet refraction disperser 1.2 of the embodiment is uniformly distributed with the plurality of jet dispersion protrusion piles 28, when the sewage jet spray horizontally sprayed by any jet spray pipe 19 impacts the first jet refraction surface 64 on the first jet refraction disperser 1.1 and the second jet refraction disperser 1.2, the sewage jet spray rapidly dispersed into fine splashed spray is splashed in the ozone gas filling cavity 42 under the collision and blocking of the plurality of jet dispersion protrusion piles 28, the fine splashed spray has sufficient contact area with ozone gas in the ozone gas filling cavity 42, and finally the fine splashed spray falls back to the sewage liquid surface 43 in the ozone sterilization aeration tank 47, and the fine splashed spray fully contacts and absorbs ozone in the ozone gas filling cavity 42 when floating in the ozone gas filling cavity 42, finally, the fine splashed water drops back to the sewage liquid level 43 in the ozone sterilization aeration tank 47, and then the dissolved ozone is brought back to the sewage in the ozone sterilization aeration tank 47;
when the sewage jet spray horizontally sprayed by any jet spray pipe 19 hits the third jet refraction surface 61 or the fourth jet refraction surface 63 on the first jet refraction disperser 1.1, the second jet refraction disperser 1.2 and the third jet refraction disperser 1.3, a "folded jet 71" is formed, as marked in fig. 8, the folded jet 71 being folded back due to its direction, and since the energy has a shorter range to attenuate splash splashing after three times of refraction, the larger particle water droplets formed by the water jet emitted by the 'folded jet 71' finally fall mostly near the first virtual circle 52 in fig. 1, continuous raindrop splash is formed at the liquid level 43 within the range of the first virtual circle 52, the contact area between the sewage at the liquid level 43 near the first virtual circle 52 and the ozone in the ozone gas filling cavity 42 is increased, and the ozone absorption efficiency is increased; moreover, a plurality of horizontal wavy jet flow decelerating plates 25 are distributed on the arc transition surface 62 on the third jet flow refraction disperser 1.3 in the embodiment from top to bottom, and a wavy decelerating channel 24 is formed between the adjacent jet flow decelerating plates 25 to play a role in decelerating jet flow, so that the range of the 'folded jet flow 71' generated on the third jet flow refraction disperser 1.3 is shorter, a certain range gradient is formed, and the range of continuous raindrops falling into the splash at the liquid level 43 near the first virtual circle 52 is wider;
because a plurality of horizontal linear drainage plates 27 are distributed on the second jet refraction surface 65 on the first jet refraction disperser 1.1, the second jet refraction disperser 1.2 and the third jet refraction disperser 1.3 in the embodiment from top to bottom, a jet linear drainage groove 29 is formed between the adjacent linear drainage plates 27; when sewage jet spray horizontally sprayed by any jet spray pipe 19 impacts the second jet refraction surface 65 on the first jet refraction disperser 1.1, the second jet refraction disperser 1.2 and the third jet refraction disperser 1.3, the sewage jet spray is directly sprayed out in the form of a first refraction jet 73 shown in the figure 8, and the first refraction jet 73 is refracted for only one time and is not blocked by the dispersion convex pile 28, so that most of large particle water drops formed by the water jet sprayed out by the first refraction jet 73 finally fall near the second virtual circle 51 shown in the figure 1, continuous raindrop falling spray is formed at the liquid level 43 in the range of the second virtual circle 51, the contact area between the sewage at the liquid level 43 near the second virtual circle 51 and ozone in the ozone gas filling cavity 42 is increased, and the ozone absorption efficiency is increased; a plurality of wavy drainage plates 27 are distributed on the first jet refraction surface 64 on the third jet refraction disperser 1.3 from top to bottom, and wavy jet deceleration drainage grooves 30 are formed between adjacent wavy drainage plates 27; the wavy jet flow deceleration drainage groove 30 plays a certain deceleration role in the second refraction jet flow 72 after being refracted on the first jet flow refraction surface 64, so that the range of the second refraction jet flow 72 generated on the third jet flow refraction disperser 1.3 is shorter than that of the first refraction jet flow 73, a certain range gradient is formed, and continuous raindrops formed at the liquid level 43 near the second virtual circle 51 are more uniform and wider;
the overall effect is that the entire ozone gas filling cavity 42 is filled with fine splashed spray, raindrops falling spray are formed widely and uniformly on the entire sewage liquid level 43, the contact area of the ozone gas filling cavity 42 and the sewage is increased overall, and the ozone absorption efficiency is improved overall to the maximum extent.
The above is based on the analysis after simplification, because the bent plate 18 in the shape of a "herringbone" on the first jet refraction disperser 1.1, the second jet refraction disperser 1.2 and the third jet refraction disperser 1.3 also forms a certain centrifugal force to the impinged jet in the process of rotating along itself, in practical situations, the splash and distribution of the splash in the ozone gas filling cavity 42 are more disordered and extensive, the wider and disordered the splash in the ozone gas filling cavity 42 is, the larger the contact surface is, the higher the absorption efficiency is, and this is also related to the output power of the motor 11.
The above is only a preferred embodiment of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
