At this time, the condensate delivery pipe 16 sends the condensed waste water generated by the refrigeration of the ship air conditioner 1 into the rotating beam shaft 13 after filtration through a small delivery pump, and then sprays it from a plurality of spraying grooves 39 to the inner arc surface of the contact treatment disk 12. When the dirty return air from the ship's living area contacts the contact treatment disk 12, it fully contacts the water layer on the inner arc surface of the contact treatment disk 12, and a large amount of water-soluble harmful odorous gases in the dirty air are dissolved in water for preliminary purification. The gas after preliminary purification enters the rotating placement groove 9 through the transfer delivery groove 10, and contacts and treats the adsorption material in the hollow cover 18, thereby improving the purification and regulation quality of the ship's ventilation.

[0021] Embodiment 2 On the basis of the first embodiment, a floating dust treatment component is provided to initially filter the dust and dirt of the reflux dirty air entering the joint groove 6, and the floating dust treatment component is arranged on one side of the ventilation treatment box 5, and the floating dust treatment component includes a circulating filter cloth 21 and a cleaning brush roller 24, and one side of the circulating filter cloth 21 covers the joint groove 6, and a driving cavity is provided on the side of the ventilation treatment box 5 close to the joint groove 6, and a circulating active groove 19 is provided in the driving cavity, and one side of the circulating active groove 19 is connected with the upper end of the joint groove 6, and four circulating driving rollers 20 are horizontally symmetrically plugged in the four sides of the circulating active groove 19 through bearings, and the circulating filter cloth 21 is plugged into the circulating active groove 19 and overlapped with the four circulating driving rollers 20, and the circulating filter cloth 21 is The width is greater than the diameter of the engaging groove 6. A groove 23 and a cleaning groove 22 are respectively provided on the upper and lower sides directly below the circulating active groove 19. A cleaning brush roller 24 is horizontally inserted in the groove 23 through a bearing. Guide rollers 25 are horizontally inserted in the groove 23 near the cleaning brush roller 24 through bearings. One side of the circulating filter cloth 21 is inserted into the groove 23 and overlaps the cleaning brush roller 24 and the two guide rollers 25 respectively. The circulating filter cloth 21 can be circulated and rotated through four circulating driving rollers 20 to improve the filtering quality of the continuous operation of the air conditioner. When the circulating filter cloth 21 rotates, the cleaning brush roller 24 can brush the surface of the circulating filter cloth 21 to improve the continuous service life of the circulating filter cloth 21. In addition, rubber washers can be provided on both sides of the joint groove 6 connected to the circulating movable groove 19, and the circulating filter cloth 21 can avoid air overflow as much as possible when moving in the two rubber washers; A collecting groove 33 is vertically opened at the lower end of the treatment groove 8, and the lower end of the collecting groove 33 is connected to the lower end of one side of the cleaning groove 22. A sewage groove 35 is opened on the side of the ventilation treatment box 5 close to the cleaning groove 22. The lower end of the cleaning groove 22 is connected to one side of the sewage groove 35, and an extraction pipe 36 is inserted at one side of the sewage groove 35. The liquid level in the extraction pipe 36 is always higher than the height of the circulation groove 34, so that the dust brushed off is collected and discharged.

[0022] In this embodiment, when the circulating filter cloth 21 rotates, the air entering the ventilation treatment box 5 is efficiently filtered. After filtration, the gas containing a small amount of dust contacts the contact treatment disk 12 with water on the inner arc surface through the guide pipe 11. The dust quickly blends with water. The contact treatment disk 12 further treats the gas containing floating dust. Then, the sewage containing dust and harmful gases falls from the contact treatment disk 12 into the treatment tank 8, and then enters the cleaning tank 22 from the collecting tank 33 and the circulation tank 34. At this time, the dust brushed off the surface of the circulating filter cloth 21 by the cleaning brush roller 24 falls into the lower part of the cleaning tank 22. Since the liquid level in the sewage tank 35 is higher than the height of the circulation tank 34, the gas in the treatment tank 8 will not enter the cleaning tank 22. At the same time, there is always a certain amount of liquid at the bottom of the cleaning tank 22. The liquid at the bottom of the cleaning tank 22 can dissolve the dust brushed off by the circulating filter cloth 21, and then the sewage is regularly extracted from the sewage tank 35 through the extraction pipe 36 for discharge, thereby improving the utilization rate of the air-conditioning condensate water and saving energy and protecting the environment.

[0023] Embodiment 3 On the basis of the second embodiment, a driving component is provided to drive and control the mechanism that needs to rotate. The driving component includes a first synchronous gear 29 and a second synchronous gear 30. The first synchronous gear 29 and the second synchronous gear 30 are synchronously rotated, and the first synchronous gear 29 and the second synchronous gear 30 respectively rotate the air outlet 3, the circulating filter cloth 21 and the cleaning brush roller 24. The first synchronous gear 29 and the second synchronous gear 30 are vertically rotated and arranged on both sides of the driving cavity. A pulley 31 is coaxially provided on one side of the first synchronous gear 29 and the second synchronous gear 30. A synchronous belt 32 is sleeved between the two pulleys 31, and a protective cover 37 is vertically provided on one side of the driving cavity by bolts. The condensate delivery pipe 16 can also be fixed to one side of the protective cover 37 by a fixed support plate. When the protective cover 37 is fixedly installed on the ventilation treatment box 5, the condensate delivery pipe 16 is plugged and connected to the water replenishment tank 15, so that when the rotating beam shaft 13 rotates, the condensate delivery pipe 16 remains stationary; One side of the rotating beam shaft 13 passes through the driving cavity and the protective cover 37. The rotating beam shaft 13 is placed in the driving cavity and is sleeved with a third driven gear 28 on one side. One side of the cleaning brush roller 24 is inserted into the driving cavity and is sleeved with a first driven gear 26. Both sides of the second synchronous gear 30 are respectively meshed and connected with the first driven gear 26 and the third driven gear 28. One side of the circulating driving roller 20 near the first synchronous gear 29 in the circulating active groove 19 is inserted into the driving cavity and sleeved with a second driven gear 27, and one side of the first synchronous gear 29 is meshed and connected with the second driven gear 27. When the first synchronous gear 29 rotates, the second synchronous gear 30 is synchronously controlled to rotate by the pulley 31 and the synchronous belt 32. At this time, the first synchronous gear 29 drives the circulating driving roller 20 connected The second driven gear 27 rotates to control the circulating filter cloth 21 to rotate in a circular manner. The second synchronous gear 30 simultaneously controls the first driven gear 26 and the third driven gear 28 to rotate, so as to realize the self-rotation of the cleaning brush roller 24 and the rotating beam shaft 13. When the rotating beam shaft 13 rotates, the contact treatment disc 12 rotates in the treatment tank 8 along the virtual axis of the rotating beam shaft 13. Since the contact treatment disc 12 is arranged to be inclined, when the contact treatment disc 12 rotates, the reflux gas is improved to fully contact the water layer on the inner arc surface of the contact treatment disc 12, and it is convenient for the sewage to fall into the collection tank 33. When the rotating beam shaft 13 rotates, the hollow cover 18 can rotate synchronously to avoid the activated carbon from being hardened in the hollow cover 18, so that the activated carbon can creep in the hollow cover 18, thereby improving the utilization rate of the activated carbon adsorption purification; Since the circulating drive roller 20 and the cleaning brush roller 24 are located on both sides of the circulating filter cloth 21, when the first synchronous gear 29 and the second synchronous gear 30 synchronously drive the two to rotate, when the circulating filter cloth 21 rotates counterclockwise, the cleaning brush roller 24 also rotates counterclockwise. When the circulating filter cloth 21 passes through the cleaning brush roller 24, the cleaning brush roller 24 can fully brush and clean the surface of the circulating filter cloth 21.
