Description

Compost Fermenter of Organic Waste Composting Facility

The present invention relates to a compost fermentation tank of an organic waste composting facility for fermenting organic wastes to produce compost, and more particularly, to a compost fermentation tank of an organic waste composting facility in which air supplied for promoting fermentation can be evenly dispersed. will be.

Organic wastes such as food waste, livestock manure, sewage sludge, etc. are processed to fertilize the organic wastes in order to treat and recycle them.

Looking at the process of producing organic compost by fermenting organic waste, the organic waste composting equipment produces the compost by allowing the organic waste in the fermenter to come into contact with the air continuously to ferment.

For example, looking at the compost fermentation tank 10 according to the prior art as shown in Figure 1, has a structure in which a plurality of air supply pipe 11 is arranged at intervals on the bottom surface of the compost fermentation tank 10. The organic waste is composted through the fermentation process by introducing an organic waste or a mixture of organic waste and a moisture control material, which is a raw material of the compost, into the compost fermentation tank and supplying air to promote fermentation through the air supply pipe 11. do.

The organic waste (1), which is a compost raw material, and a moisture control material are introduced into the compost fermentation tank (10), and mixed with the stirring facility moving along the compost fermentation tank (10). Since the organic waste (1) contains a large amount of water, by inputting a moisture control material such as sawdust, wood chips, rice husk, rice straw, etc., the moisture contained in the organic waste (1) is adjusted, and mixed with a stirring facility. .

On the other hand, the mixed layer of the organic waste (1) and the moisture control material that the air ejected from the air supply pipe 11 is evenly distributed and compost raw material in the portion where the stirring equipment does not reach the lower portion of the organic waste (1) and the moisture control material. An air diffusion layer 2 filled with particulate matter is provided to be diffused so as to be supplied. The particulate material is provided with chaff, sawdust, wood chips, volcanic stone, ceramic balls, gravel, plastic moldings, etc. to fill the lower part of the compost fermentation tank 10, the air ejected from the air supply pipe 11 is an air diffusion layer (2) It spreads through the pores evenly distributed in and is supplied to the upper organic waste (1) and moisture control material.

Therefore, the organic waste 1 and the moisture control material are present in a mixed state in the upper part of the compost fermentation tank 10, and the air is supplied from the air supply pipe 11 in a state in which an air diffusion layer 2 is provided. As a result, the organic waste 1 is fermented. The air diffusion layer 2 composed of particulate matter diffuses the air ejected from the air supply pipe 11 so that the air is evenly supplied to the organic waste.

However, the compost fermentation tank 10 of the organic waste composting facility according to the prior art as described above, as shown in Figure 1, the ejected air is not evenly diffused in the organic waste (1) the inner wall of the compost fermentation tank 10 There is a problem that is supplied concentrated. That is, in the central portion of the compost fermentation tank 10, the air resistance is strong in all directions due to the viscosity of the organic waste, etc., and the ventilation resistance is relatively weak in the inner wall portion of the compost fermentation tank 10, the air supply pipe (11) The air blown out at is not evenly diffused in the mixed layer of the organic waste (1) and the moisture control material. Therefore, the air blown out from the air supply pipe 11 is concentrated on the inner wall of the compost fermentation tank 10 and is relatively sparsely supplied at the central part, so that the fermentation of the organic waste 1, which is a raw material of the compost, is not only uneven. Fermentation is delayed, there is a problem that the organic waste (1) must be periodically mixed through a separate mechanism to solve this problem.

The present invention has been invented to solve the above problems, an object of the present invention is to provide a compost fermentation tank of the organic waste composting facility to ensure that the air supplied to the inside of the compost fermentation tank of the organic waste composting equipment is evenly spread to the organic waste of the compost raw material. There is this.

In the compost fermentation tank of the organic waste composting facility according to the present invention for achieving the above object, in the compost fermentation tank of the organic waste composting facility to produce the compost by fermenting the organic waste, the moisture control material is mixed on the top of the compost fermentation tank An air supply pipe accommodating the organic wastes, the particulate material forming an air diffusion layer in the lower portion, and having an air outlet at intervals, spaced apart from each other on the bottom of the compost fermentation tank, and the compost fermentation tank Extends from the inner wall or the bottom surface of the convex fermentation tank, and is formed along the longitudinal direction of the compost fermentation tank, and the tip is positioned lower than or equal to the upper surface of the air diffusion layer so as to prevent the air ejected from the air supply pipe from being biased toward the inner wall of the compost fermentation tank. It characterized in that the air inducing means are included.

Preferably, the air induction means is an air induction wall formed at a height lower than or equal to an upper surface of the air diffusion layer along an inner wall of the compost fermentation tank.

Here, the air induction wall may be formed with a plurality of through holes formed through the air induction wall.

On the other hand, the air inducing means may be an air induction film extending from the inner wall of the compost fermentation tank and formed along the inner wall of the compost fermentation tank.

According to the compost fermentation tank of the organic waste composting apparatus according to the present invention having the above configuration, the air ejected from the air supply pipe and passed through the air diffusion layer is not concentrated on the inner wall of the compost fermentation tank by the air induction means. Ascending and spread evenly over the entire area of organic waste.

In addition, the air is evenly spread and supplied to the organic wastes, thereby improving the production speed of the compost, and it is not necessary to periodically stir the organic wastes in the compost fermentation tank.

Hereinafter, with reference to the accompanying drawings will be described a compost fermentation tank of an organic waste composting facility according to a preferred embodiment of the present invention.

2 and 3 are a cross-sectional view and a plan view of the compost fermentation tank of the organic waste composting facility according to an embodiment of the present invention.

The compost fermentation tank 10 of the organic waste composting apparatus according to the present invention comprises a compost fermentation tank 100 as an inner wall formed to have a height at the bottom, the air outlet (11a) is formed at intervals and the compost fermentation tank 10 A plurality of air supply pipes (11) spaced apart from each other at the bottom of the bottom and extending from the inner surface of the compost fermentation tank (10) is formed along the longitudinal direction of the compost fermentation tank (10), the tip of the air diffusion layer (2) It is located lower than or equal to the upper surface of the air supply means comprises air inducing means to prevent the air ejected from the air supply pipe 11 to be biased to the inner wall of the compost fermentation tank (10).

Looking at the structure of the compost fermentation tank 10, an inner wall is formed to have a height around the bottom and the bottom forming the bottom. The bottom and inner walls form the inner surface of the compost fermentation tank 10, accommodate the organic waste 1 to be composted therein, and ferment the organic waste 1 to compost. In particular, the organic waste 1 mixed with the moisture control material is accommodated in the upper portion, and the particulate matter forming the air diffusion layer 2 in the lower portion is accommodated.

The air supply pipe 11 is arranged in plurality at the bottom of the compost fermentation tank 10 of the organic waste composting facility. The air supply pipe 11 is formed with an air outlet (11a) for ejecting air into the interior of the compost fermentation tank 10 at intervals. The air supply pipe 11 is arranged in plural to be spaced apart from each other on the bottom surface of the compost fermentation tank 10 so as to evenly supply air to the entire area of the compost fermentation tank 10. Therefore, the air outlet port 11a is disposed on the bottom of the compost fermentation tank 10 so that air can be supplied evenly to the bottom of the compost fermentation tank 10.

In this case, the air supply pipe 11 is connected to an air supply source (not shown), for example, a turbo fan, a blower, an air compressor, an air pump, and the like.

The air inducing means is for preventing the air ejected from the air supply pipe 11 to be concentrated on the inner wall of the compost fermentation tank 10, from the inner surface of the compost fermentation tank 10, that is, from the inner wall or the inner bottom surface. It protrudes and is formed along the longitudinal direction of the compost fermentation tank 10, thereby preventing the tip of the protruding air guide means from concentrating on the inner wall of the compost fermentation tank 10. In this way, the air inducing means prevents the air ejected from the air supply pipe 11 from being concentrated on the inner wall of the compost fermentation tank 10.

As an example of such an air guide means, an air guide wall 12 as shown in Figs. The air induction wall 12 is formed along the inner wall at intervals from the inner wall of the compost fermentation tank 10. The air induction wall 12 is for preventing the air ejected from the air supply pipe 11 located at the bottom of the compost fermentation tank 10 to be concentrated on the inner wall of the compost fermentation tank 10 excessively. Therefore, the air induction wall 12 is formed at intervals on the inner wall of the compost fermentation tank 10, so that the flow of air blown out of the air outlet (11a) and concentrated on the inner wall of the compost fermentation tank 10, the air induction The wall 12 is blocked off so that it is evenly supplied to the compost fermentation tank 10.

The air induction wall 12 is preferably formed along the inner wall of the compost fermentation tank 10.

At this time, the height of the air induction wall 12 is formed at a height equal to or lower than the upper surface of the air diffusion layer (2) in the fermentation tank (10). That is, the air induction wall 12 is formed to be lower than or equal to the upper surface of the air diffusion layer 2, so that the upper end of the air induction wall 12 is located in the organic waste 1 to be supplied from the air supply pipe 11. There is a problem that the air can not be supplied to the entire area of the compost fermentation tank (10). Therefore, the upper end of the air induction wall 12 is located lower than or equal to the upper end of the air diffusion layer 2, so that a part of the air induced by the air induction wall 12 is the upper end of the air induction wall 12 In order to be also supplied to the inner surface of the compost fermentation tank 10 in

The air ejected from the air supply pipe 11 by the air induction wall 12 is not concentrated by the air induction wall 12 to the inner wall of the compost fermentation tank 10 and is evenly distributed over the entire area of the compost fermentation tank 10. do. Therefore, not only the portion adjacent to the inner wall of the compost fermentation tank 10 but also the middle portion of the compost fermentation tank 10, air is supplied to the mixture of the air diffusion layer 2, the organic waste 1, and the moisture control material, so that the compost fermentation tank 10 The organic waste 1 can be composted by promoting the fermentation of the organic waste 1 evenly over the entire area.

That is, as shown in Figure 2, the air ejected from the air outlet (11a) flows as shown by the arrow shown as '→', so that it is not concentrated to the inner wall of the compost fermentation tank 10, not only to the inner wall but also to the central portion It can be seen that evenly supplied. Here, the arrow shown as '⇒' shows the velocity distribution in each part, and it can be seen that air is supplied to the organic waste at an even speed in the inner wall and the central part.

In addition, the air induction wall 12 may be formed with a through hole 12a penetrating both ends of the air induction wall 12. Although the air induction wall 12 prevents the air supplied by the air supply pipe 11 from being concentrated on the inner wall of the compost fermentation tank 10, the air induction wall 12 and the compost fermentation tank 10 The adverse effect of blocking the supply of air between the inner walls can occur. By forming a through hole 12a penetrating the air induction wall 12 in order to block this, it is possible to sufficiently supply the air required for fermentation between the air induction wall 12 and the inner wall of the compost fermentation tank 10.

On the other hand, as another example of the air induction means, it may be an air induction film 13 as shown in FIG. The air induction film 13 protrudes from the inner wall of the compost fermentation tank 10 and is formed along the inner wall. The air induction film 13 protrudes from the inner wall of the compost fermentation tank 10 so that the tip of the air induction film 13 is spaced apart from the inner wall of the compost fermentation tank 10 and is located above the bottom. The air induction film 13 is also located inside the air diffusion layer 2, so that the air blown out from the air supply pipe 11 is not concentrated on the inner wall of the compost fermentation tank 10, The organic waste 1 and the moisture control material, which are the raw materials of the compost, are evenly dispersed by the air diffusion layer 2 therein.

In FIG. 4, the air is evenly supplied to the inside of the organic waste 1 from the inside of the compost fermentation tank 10 as shown by the arrow indicated by '→' to promote fermentation of the organic waste 1, and is shown as '⇒'. It can be seen that the velocity is distributed as shown by the arrow.
