Description

  The present invention relates to an agitation device for a deodorization treatment carrier in a biological deodorization device, and more particularly, to an agitation device for a deodorization treatment carrier in a biological deodorization device that can uniformly and reliably agitate the entire deodorization treatment carrier filled in a biological deodorization tank. It is about.

  Conventionally, gas bodies with bad odor generated and discharged from production factories, sewage treatment plants, and the like have been deodorized and then released into the atmosphere. The gas body with bad odor often contains, for example, methane gas, hydrogen sulfide gas, VOC (volatile organic compound) gas, etc., and these gas bodies with bad odor (hereinafter referred to as “processing gas”). For example, as shown in FIG. 3, a deodorizing treatment tank T having a required amount of deodorizing treatment function, such as a carrier of a deodorizing treatment microorganism, for example, a ceramic or plastic carrier (hereinafter referred to as “deodorizing treatment carrier”). In order to prevent the deodorizing treatment carrier from being consolidated and to maintain the processing gas passage performance, the comb-like stirring rod L is inserted into the deodorizing treatment carrier, and the comb-like stirring rod is rotated. The deodorizing treatment tank is agitated, a processing gas is injected into the deodorizing treatment tank, and the deodorizing treatment microorganisms in the deodorizing treatment carrier are propagated to perform the required deodorizing treatment.

  By the way, in the conventional biological deodorization apparatus that rotates the comb-shaped stirring bar, the stirring performance of the deodorizing treatment carrier is poor because the comb-shaped stirring bar is simply swung along the same core circle, and the entire inside of the tank is uniformly distributed. In particular, the deodorizing treatment tank inner bottom and surface portions of the deodorizing treatment carrier cannot be sufficiently stirred, and compaction occurs at the bottom of the deodorizing treatment tank, and processing gas passage loss due to the consolidation of the deodorizing treatment support increases. At the same time, there is a problem that this compaction inhibits the growth of deodorizing microorganisms and the deodorizing ability decreases.

  In view of the problems of the deodorizing treatment carrier stirring device in the biological deodorizing device, the present invention provides a deodorizing treatment carrier in the biological deodorizing device that can uniformly and reliably stir the entire deodorizing treatment carrier filled in the biological deodorizing device. It aims at providing a stirring apparatus.

  To achieve the above object, the deodorizing carrier agitating device in the biological deodorizing apparatus of the present invention has a stirring rod on a drive shaft arranged so as to penetrate the inside of the deodorizing carrier filled in the carrier support floor in the deodorizing tank. A screw type stirring blade is pivotally attached to both ends of the stirring rod in a vertical direction so that the deodorizing treatment carrier is stirred by rotating the screw type stirring blade by the turning drive means when the stirring rod turns together with the drive shaft. It is characterized by doing so.

  In this case, a stirring rod on which a screw type stirring blade is pivotably attached can be disposed for each carrier support floor in the deodorizing treatment tank.

  Also, the length of both ends of the stirring rod attached to the drive shaft is made different, and the center part of the carrier support floor is supported by the screw type stirring blade attached to the short side end, and the carrier is supported by the screw type stirring blade attached to the long side end. The outer periphery of the floor can be stirred.

  Further, the turning direction of the screw type stirring blade can be set to the direction in which the deodorizing treatment carrier is lifted from the bottom of the carrier support floor.

  Further, the swirl driving means of the screw type stirring blades can be engaged with a sprocket fixed to the screw type stirring blade shaft end in a circular rack disposed and fixed above the carrier support floor.

  Further, the turning directions of the screw type stirring blades attached to both ends of the stirring rod can be set differently.

  According to the stirrer for the deodorizing treatment carrier in the biological deodorizing apparatus of the present invention, a stirring rod is provided on the drive shaft disposed so as to penetrate the deodorizing treatment carrier filled in the carrier support floor in the deodorizing treatment tank, and the stirring is performed. A screw-type stirring blade is pivotably attached to both ends of the rod so that the stirring rod can be swung together with the drive shaft. Since the screw-type stirring blades can be rotated and revolved by the swirling, the deodorizing treatment carrier can be uniformly and reliably mixed and stirred from the bottom of the carrier support floor to the surface portion and throughout the carrier support bed.

  In addition, by arranging a stirring rod with a screw-type stirring blade that can be swiveled for each carrier support bed in the deodorization treatment tank, even if the inside of the deodorization treatment tank is multistage, It is possible to reliably mix and stir the deodorizing carrier.

  Also, the projecting lengths at both ends of the agitation rod attached to the drive shaft are made different, and the central part of the carrier support floor is attached by the screw type agitation blade attached to the short side end part, and the carrier is made by the screw type agitation blade attached to the long side end part. By stirring the outer periphery of the support bed, it is possible to reliably mix and stir the deodorizing treatment carrier in the entire area of the support bed by simply turning the stirring rod.

  In addition, the swirling direction of the screw-type stirring blade is set so that the deodorizing treatment carrier is swept up from the carrier supporting floor bottom to the surface side, thereby preventing the deodorizing treatment carrier from being consolidated at the carrier supporting floor bottom. The processing state can be properly maintained.

  Further, by rotating the swirl driving means of the screw type stirring blades with the sprockets fixed to the shaft ends of the screw type stirring blades in a circular rack disposed and fixed above the carrier support floor, other power can be obtained. The deodorizing carrier can be mixed and stirred by revolving and rotating the screw-type stirring blades via a sprocket meshing with the circular rack by moving along the circular rack without using it.

  Moreover, the deodorizing treatment carrier can be mixed and stirred at the same time by setting the turning directions of the screw type stirring blades attached to both ends of the stirring rod to be different from each other.
