Description of the Related Art As a method for treating organic waste such as garbage and livestock excrement collected from ordinary households, there is a method of aerobically fermenting in a fermenter to compost, reduce or eliminate the volume. In this treatment, odorous gas such as ammonia is generated in the fermenter along with aerobic fermentation of waste. This odor not only makes the operator uncomfortable, but if it leaks to the outside, it becomes a cause of environmental deterioration. Therefore, deodorization processing has been conventionally performed to collect the odor and remove the odor. Specifically, a hood that covers the fermentation tank is provided above the fermentation tank, and the odorous gas in the fermentation tank is sucked from one or more suction ports provided in the hood to be introduced into the deodorizing device, which is deodorized. Later, it is released to the atmosphere.

とする。[Problems to be Solved by the Invention] By the way, the fermenter is equipped with an agitator for agitating the raw materials in the fermenter in order to promote fermentation, and the above-mentioned hood should be installed so as not to interfere with this agitator. A large one is required. Further, the hood is not a completely closed structure so that the agitator can be easily maintained and inspected, and is arranged so as to leave a gap between the hood and the fermentation tank. However, as described above, a large hood having a gap requires a large suction device having a strong suction force to collect odorous gas, which causes a problem that the equipment cost of the entire fermentation treatment device increases. Further, even if suction is performed with a strong suction force, the gap between the hood and the fermenter is far from the suction port, and odorous gas is unavoidably leaked from this gap, and there is a problem of slightly contaminating the surroundings. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an odor recovery device for a fermentation tank that can reliably recover odorous gas even with a device having a low suction force.

For this reason, the hood and the suction device for the hood can be omitted if desired, the facility cost and the running cost can be reduced, and the overall height of the device can be reduced to downsize the device. Further, if the hood is provided as usual and the odor is collected from both the hood and the side wall, the odor can be reliably collected. Even in this case, the suction device provided in the hood can be changed to one having a low suction force, and a high-performance suction device is considerably expensive and also increases running costs. It becomes possible to reduce.

If suction control means capable of controlling the suction operation of each divided suction port individually or in plurals (hereinafter, simply referred to as each divided suction port) is provided, the suction / stop operation can be controlled for each divided suction port,
The suction force can be changed for each divided suction port, and the odor can be sucked in an optimum suction state according to the position of the fermentation tank. For example, the suction force is increased at a place where the odor is generated more, and the suction force is lowered or stopped at a place where the odor is generated very little. Thereby, the energy for suction can be efficiently consumed. Further, at the place where stirring is performed or in the vicinity thereof, it is possible to prevent the raw material from mixing into the suction port by reducing the suction force or stopping the suction. The control in the vicinity of the stirrer can be linked to the movement of the stirrer, and a limit switch or a sensor for detecting the movement of the stirrer can be used.

First, the organic material 3 having adjusted water content, particle size, etc. is charged into the fermenter 1 from the charging section 4. Organic materials put in 3
Is stirred and transferred by the operation of the stirring device 10, and gradually moves from the input side to the discharge side. Along with this operation, air is forcibly sent from the air supply blower 8 to the air chamber 7 via the air supply pipe 8a and the valve 8b, and this air further passes through the ventilation holes of the porous bottom plate 6 on the air chamber 7. The organic material 3 in the fermenter 1 is supplied with air. Due to this air supply, the organic material 3 is actively contacted with oxygen and aerobic fermentation proceeds, and along with this, odorous gas is generated. Then, the odorous gas is not diffused and is immediately sucked by the odorous suction device 16 through the odorous suction port 15 and further sent to the deodorizing device 17 to be deodorized. After that, it is released to the atmosphere, but it is sufficiently deodorized and does not pollute the surroundings.

There is no need to install a recovery device. In the fermentation tank in which the odor is well recovered, the fermentation of the organic material 3 proceeds, and the organic material fermented to a desired degree is finally taken out from the discharge part 5.

Close the valve to stop odor aspiration. This prevents the organic material 23 scraped up by stirring from entering the nozzle hole 20. By sequentially performing this operation in parallel with the nozzle holes 20 along with the movement of the stirrer, the deterioration of the odor recovery efficiency is minimized and the nozzle holes 20 are provided in the entire fermentation tank.
Effectively prevent the mixing of organic materials into. Further, in the above apparatus, suction and stop operations were controlled for the nozzle hole 20 near the agitator, but it is also possible to adjust the suction force of the nozzle hole 20 depending on the position of the fermenter, whereby the fermentation The odor can be more efficiently sucked in according to the difference in the degree of progress.
