  • the life time of the impregnated activated carbon 36 as the deodorizer can be extended by thus capturing and removing fine dust (the fine cut chips contained in the bubbles 9b floating on the surface of the waste water 9 stored in the tank 7) and the moisture by the filter 37.
  • the filter 13 When the deodorization system is provided with the dehydration filter 13, the filter 13 may be disposed above the cover plate 7a of the tank 7, and the drain valve 19 of the filter 13 may be connected to an upper part of the tank 7 by a hose. Then the waste water may thereby be returned through the drain valve 19 into the tank 7.
  • the waste water stored in the bottom of the impact separator 50 may be returned through a hose, not shown, into the tank 7 by a pump, not shown. In this case, if the cooling water contains a defoaming agent, the defoaming agent can be saved when the stored waste water is thus returned into the tank 7.
  • the deodorization apparatus 15 includes parts different in shape and arrangement from those of the deodorization apparatus 15 in the second embodiment. That is, in this embodiment, an elongated blower 39 is set in a vertical position, the suction side of the blower 39 is connected to a suction box 38 by a hose 56.
  • the deodorization apparatus 15 in this embodiment is not provided with any parts corresponding to the drain pipe 39b, and a plurality of discharge holes, not shown, are formed in a part of the outer case 20 facing the blower.
  • the discharge holes are covered with a discharge filter 57, and the air discharged from the blower 39 is discharged outside after being filtered by the discharge filter 57.
  • the deodorization apparatus 15 in this embodiment is provided with a vertically elongated water storage tank 24 and an impact separator 50 having a vertically elongated case 51 provided with a single separating plate 52.
  • the impact separator 50 is disposed in an upper part of the deodorization apparatus 15, the deodorization device 36 is disposed beside the separator 50, the water storage tank 24 is disposed below the separator 50, and the blower 39 is disposed beside the tank 24.
  • the separator 50 and the tank 24 are disposed in a vertical arrangement, and the deodorization apparatus 15 has a compact construction.
  • the deodorization system in the fourth embodiment was used practically.
  • the most part of substances stored in the tank 24 was the waste water scarcely containing the bubbles. By colliding the bad-smelling air with the separation plate 52, it can be done to extinguish the most part of the bubbles contained in the air.
  • the volume of the waste water stored in the tank 24 after grinding one hundred lenses was about 1.1 liters. If the waste water (cooling water) contains a defoaming agent, the defoaming agent can be saved when the deodorization system, similarly to those in the first to the third embodiments, returns the waste water removed from the bad-smelling air and stored in the dehydration filter 13 and in the tank 24 through a hose, not shown, by a pump, not shown, to the waste water tank 7.
  • a deodorization system in a fifth embodiment according to the present invention will be described with reference to Fig. 8.
  • a funnel like separator 60 for separating the waste water and the bad- smelling air from each other is disposed between the drain hose 8 in the first embodiment and the cover plate 7a of the waste water tank 7 in the first embodiment.
  • the suction hose 12 is connected to this separator 60.
  • the separator 60 has a tapered part 61 tapered in a manner such that the diameter of its lower part is smaller than that of its upper part, a cylindrical part 62 connected to the lower end of the tapered part 61, and a top wall 63 covering the open upper end of the tapered part 61.
  • the cylindrical part 62 penetrates the cover plate 7a of the tank 7 and is hermetically fixed to the cover plate 7a.
  • a lower end part of the drain hose 8 is inserted in a penetrated hole 63a formed in the center of the top wall 63 so as to extend into the cylindrical part 62.
  • a small annular gap 64 is formed between the lower end part of the drain hose 8 and the cylindrical part 62.
