The biological adsorption box 11 is placed below the oxygenation spray hood 24 and is provided with a biological filler layer 112. The biological adsorption box 11 is placed above the air distribution plate 111 and is provided with an air inlet 113 on one side. The waste gas enters the biological adsorption box 11 from the air inlet 113, is distributed by the air distribution plate 111, and evenly enters the bottom of the air distribution plate 111, and passes through the biological filler layer 112 outside the range of the oxygenation spray hood 24, and absorbs odors through the biological filler layer 112.

[0022] In this embodiment, a second spray pipe 121 is provided on the top of the activated carbon adsorption box 12, and an air outlet 122 is provided on the side wall of the activated carbon adsorption box 12 below the second spray pipe 121. An activated carbon adsorption layer 123 is also provided in the activated carbon adsorption box 12. The gas treated by the biological adsorption box 11 enters from the bottom of the activated carbon adsorption box 12, and is discharged through the air outlet 122 after secondary adsorption by the activated carbon adsorption layer 123. The second spray pipe 121 is used for backwashing the activated carbon adsorption layer 123 to improve the utilization rate of the activated carbon adsorption layer 123. The flushing water and the excess spray water of the biological filler layer 112 are collected by the water collecting tank 13.

[0023] In this embodiment, the movable component 2 includes a driving motor 21, a rotating sleeve 22, a rotating rod 23, an oxygen-enriching spray hood 24, a sliding rod 25 and a guide rod 26. The driving motor 21 is installed on the upper surface of the center position of the air distribution plate 111. The output end of the driving motor 21 is fixedly connected with the rotating sleeve 22, and the rotating sleeve 22 is sleeved with the rotating rod 23. When the driving motor 21 works, it drives the rotating sleeve 22 to rotate, and the rotating sleeve 22 drives the rotating rod 23 to rotate. One end of the rotating rod 23 is movably connected to the center position of the upper surface of the oxygen-enriching spray hood 24, the sliding rod 25 passes through the oxygen-enriching spray hood 24, and the two ends of the sliding rod 25 are sleeved with the guide rod 26. The end of the guide rod 26 is fixedly connected to the inner wall of the biological adsorption box 11. When the rotating rod 23 rotates , which can drive the oxygen enriched spray hood 24 to move on the slide bar 25. When the oxygen enriched spray hood 24 moves to the end of the slide bar 25, it also drives the slide bar 25 to move on the guide bar 26, thereby controlling the oxygen enriched spray hood 24 to move in a rectangular path. The position below the oxygen enriched spray hood 24 is a quarter of the area of ​​the biological filler layer 112. The three-quarters of the area of ​​the biological filler layer 112 that is not blocked can filter the gas normally. The blocked biological filler layer 112 reproduces biological strains under the action of the oxygen enriched spray hood 24 to achieve an automatic repair function. Since the oxygen enriched spray hood 24 is always moving, it can continuously change the position of the automatic repair of the biological filler layer 112 to maintain the adsorption effect of the biological filler layer 112.

[0024] In this embodiment, a support spring 231 is sleeved on one end of the rotating rod 23 close to the oxygen enrichment spray hood 24, and one end of the support spring 231 is against the rotating sleeve 22. When the rotating rod 23 rotates following the rotating sleeve 22, under the restriction of the oxygen enrichment spray hood 24, the rotating rod 23 retracts and contracts in the rotating sleeve 22, and the support spring 231 is used for buffering and assisting the rotating rod 23 in resetting.

[0025] In this embodiment, a sliding hole 241 matching the sliding rod 25 is provided on the oxygenating spray hood 24, a first spray pipe 242 is provided at the upper end of the interior of the oxygenating spray hood 24, and an oxygen supply pipe 243 is provided at the lower end of the side wall of the oxygenating spray hood 24. When the oxygenating spray hood 24 moves along the rectangular path, the oxygenating spray hood 24 always covers a quarter of the area of ​​the biological filler layer 112, and sprays humidification and oxygenates the biological filler layer 112 on this area, so that the biological strains can reproduce and regenerate rapidly, and due to the shielding of the oxygenating spray hood 24, the biological filler layer 112 on this area is not passed by gas and is in a repair state.

[0026] Working process: the odor enters the biological adsorption box 11 from the air inlet 113, and the air distribution plate 111 distributes the air, and evenly enters the bottom of the air distribution plate 111, and passes through the biological filler layer 112 outside the range of the oxygenation spray hood 24. The driving motor 21 drives the rotating rod 23 to rotate the rotating position through the rotating sleeve 22, and then pushes the oxygenation spray hood 24 to move in a rectangular path under the action of the sliding rod 25 and the guide rod 26. The oxygenation spray hood 24 blocks a quarter of the biological filler layer 112, humidifies and oxygenates it, and helps the biological filler layer 112 at this location to automatically repair. The other unblocked biological filler layers 112 absorb the odor. The gas treated by the biological filler layer 112 enters from the bottom of the activated carbon adsorption box 12, and is discharged through the air outlet 122 after secondary adsorption by the activated carbon adsorption layer 123.

[0027] In summary: the utility model is a biological activated carbon deodorization adsorption box, which can adsorb odor twice by setting a biological adsorption box 11 and an activated carbon adsorption box 12, thereby improving the deodorization effect. In addition, an oxygenating spray hood 24 is arranged above the biological filler layer 112, and the oxygenating spray hood 24 is controlled to move in a rectangular path, so that the oxygenating spray hood 24 can repair the local biological filler layer 112, and the unrepaired part of the biological filler layer 112 can be adsorbed. During use, the biological strains are reproduced and regenerated, and the adsorption force of the biological filler layer 112 can be maintained for a long time.
