Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, it should be understood that the following embodiments are provided so that those skilled in the art can understand the present invention without departing from the scope and spirit of the present invention. It is not.

As shown in the drawing, the food waste treating apparatus of the present invention includes a mixing tank 10 in which the food waste is uniformly mixed with a microbial fermentation agent, a catalyst, and the like, and the high temperature and high humidity generated from the mixing tank 10. The tank is largely divided into a reservoir 20 for treating a gas, and a reservoir 20 is disposed right next to the mixing tank 10.

The mixing tank 10 is provided with a pair of agitators 30 provided with a plurality of agitating vanes, and the agitators 30 are connected to the motor 40 through a power transmission unit 41 to rotate. As a result of the driving, the food waste introduced into the mixing tank 10 is uniformly mixed with the microorganism fermentation agent and the catalyst with stirring.

In addition, a heater 50 for heating the inside of the mixing tank 10 is installed in the lower portion of the mixing tank 10, and the food waste introduced into the mixing tank 10 is mixed with the microorganism fermenter and the catalyst by the stirrer 30. When it is stirred, it is heated by the heater 50, so that the dehydration cake forming process is performed.

As a result of the dehydration cake forming process, hot and humid gas is generated in the mixing tank 10, and the hot and humid gas is processed in the water storage tank 20. That is, since the condensed water is stored in the reservoir 20, the hot and humid gas introduced into the reservoir 20 from the mixing tank 10 is ejected into the condensed water of the reservoir 20 to condense. Is as follows.

In the present embodiment, the reservoir 20 is composed of four reservoir tanks, that is, the first reservoir 21, the second reservoir 22, the third reservoir 23, and the fourth reservoir 24, which is effective condensation. It is just one example, and may be composed of one to three reservoirs or more than four if necessary.

Each of the reservoirs 21, 22, 23, and 24 stores condensed water at a predetermined level, and the first reservoir 21 is in communication with the mixing tank 10 by the first pipe line 61. In particular, the end of the first conduit 61 extends in a state of being immersed in the condensed water of the first reservoir 21, the hot and humid gas from the mixing tank 10, the first reservoir 21 and the second reservoir It is connected to the first fan 71 that provides a suction force to move smoothly toward the (22).

In addition, a porous first gas ejection member 81 is provided at the end of the first conduit 61, and the first gas ejection member 81 is provided from the mixing tank 10 through the first conduit 61. When the introduced hot and humid gas flows out into the condensed water of the first reservoir 21, bubbles are blown out while forming bubbles. When the hot and humid gas ejected into the condensate by the porous first gas ejection member 81 forms bubbles, condensation is rapidly performed because the heat exchange surface area of the gas and the condensate increases. Therefore, not only the condensation efficiency can be improved but also the required amount of condensate can be reduced.

Next, a second reservoir 22 in which condensed water is stored in a state of being in contact with the first reservoir 21 is disposed, and is formed from an upper side of the side wall of the first reservoir 21 in contact with the second reservoir 22. The second conduit 62 extends into the second reservoir 22, and a porous second gas blowing member 82 is provided at the end of the second conduit 62. As shown in FIG.

Condensation will occur.

Moreover, although the 3rd reservoir 23 and the 4th reservoir 24 are arrange | positioned in the state which opposes the said 1st reservoir 21 and the 2nd reservoir 22, these 3rd reservoir 23 and 4th reservoir Condensed water is also stored in (24), respectively. The third conduit 63 is communicated from the upper portion of the second reservoir 22 to the internal condensed water of the third reservoir 23, and remains after condensation in the second reservoir 22 on the third pipeline 63 side. A second fan 72 providing suction power is connected to the third reservoir 23 and the fourth reservoir 24 to smoothly move the gas. In addition, at the end of the third conduit 63, the third gas blowing member 83 having a porosity that allows the gas remaining after condensation in the second reservoir 22 to be ejected while forming bubbles into the condensed water of the third reservoir 23. ) Is installed. Therefore, the gas remaining after condensation in the second reservoir 22 is blown out while forming bubbles from the third gas blowing member 83 through the third pipe line 63 into the condensed water of the third reservoir 23. Condensation is achieved by car.

Similarly, the fourth conduit 64 extends from the upper sidewall of the third reservoir 23 in contact with the fourth reservoir 24 to the inside of the fourth reservoir 24, and at the end of the fourth pipeline 64. The porous fourth gas blowing member 84 is provided. Therefore, the gas remaining after condensation in the third reservoir 23 is blown out while forming bubbles into the condensed water of the fourth reservoir 24 from the fourth gas ejection member 84 via the fourth conduit 64, Condensation is achieved by car.

In this way, the hot and humid gas generated in the dehydration cake process of the food waste in the mixing tank 10 is the first reservoir 21, the second reservoir 22, the third reservoir 23, the fourth reservoir ( From the first gas ejection member 81, the second gas ejection member 82, the third gas ejection member 83, and the fourth gas ejection member 84, which are immersed in the condensed water of each reservoir while passing through 24). Sufficient condensation occurs as the bubbles are blown into the condensate while forming bubbles. The finally processed gas is discharged to the outside through the exhaust pipe passage 20b in the state of clean air.

On the other hand, the pores of the porous first gas blowing member 81 is preferably made of a size of 60 to 100 mesh in consideration of the heat exchange surface area according to the size of the bubble, and the remaining second gas blowing member 82 and The pores of the third gas ejection member 83 and the fourth gas ejection member 84 may be formed to have a size of 120 to 500 mesh smaller than this in consideration of the amount of residual gas after condensation in the first reservoir 21.

In addition, any one or more of the first to fourth reservoirs 21, 22, 23, and 24 overflows due to excess gas being blown into the condensed water of the first to fourth reservoirs 21, 22, 23, and 24. An overflow conduit 20a for discharging the condensed water that is overflowed to the outside may be provided. In this embodiment, it is illustrated as being provided on the second reservoir 22 side.
