On the other hand, the gas discharge unit 27 is connected to the gas collecting chamber 33 may be made of a pipe of the pipe form.

The gas discharge part 27 is connected to the plurality of gas separation filters 7, 9, and 11 in a pipeline.

The gas separation filters 7, 9, and 11 are mainly used to increase the purity of the methane gas. Preferably, the gas separation filters 7, 9, and 11 have a filter structure through which only methane gas passes and other gases are separated and discharged. Such gas separation filters 7, 9, and 11 may have a plurality of structures having the same structure. In the exemplary embodiment of the present invention, detailed structures of the gas separation filters 7, 9, and 11 are omitted, but any filter may be used as long as the methane gas can pass through only methane gas.

In addition, the electricity production apparatus 13 may be connected to the above-described gas separation filters 7, 9, and 11 in a pipeline to receive a high purity methane gas. As illustrated in FIG. 2, the electricity production apparatus 13 may include a gas tank 103, a boiler 105, a turbine 107, a generator 109, and a storage battery 111.

The gas tank 103 is where high purity methane gas that has passed through the gas separation filters 7, 9, 11 is stored. The boiler 105 burns methane gas to obtain heat. In addition, the turbine 107 may obtain a rotational force by using the heat burned by the boiler 105. The generator 109 produces electricity according to the rotation of the turbine 107. And the storage battery 111 may store the electricity produced by the generator 109. The electricity generating device 13 is not limited to the example described in the embodiment of the present invention, and may have various structures.

Referring to the operation of the power generation device using the livestock waste treatment apparatus as described above are as follows.

First, organic waste such as livestock manure is supplied to the inner processing chamber 31 through the manure supply unit 23. At this time, the livestock manure is supplied to the inner treatment chamber 31 in a liquid state, a mixture of waste and solids. Then, livestock manure containing a large amount of solids is collected in the inner space surrounded by the wall 51. Of course, at this time, the valve 59 connected to the conduit between the reactor 21 and the liquid ratio collecting unit 53 is in a locked state.

As shown in FIG. 4, the livestock manure is preferably filled with a water surface W at a position such that the upper portion of the wall 51 can be covered. The end portions of the manure supply 23 and the solids passage 41 are also arranged below the water surface W.

In this way, a constant amount of livestock manure is filled in the treatment chamber 30.

Then, air is supplied to the inner processing chamber 31 through the air supply 25. As shown in FIG. 5, as the motor 73 rotates at a high speed, the air supply 25 generates a negative pressure in the air supply pipe 77 while the rotary vanes 75 rotate. Air is introduced into the inner processing chamber (31).

Therefore, the fermentation can be smoothly made by aerobic microorganisms while supplying sufficient external air to the interior of the inner processing chamber 31. In particular, as the rotary blade 75 rotates, the livestock manure of the processing chamber 31 is rotated, and at this time, the solid content is also rotated together, and high frictional heat is generated, so that the temperature of the livestock manure accommodated in the processing chamber 31 is about 70 to 90. Rise to ° C.

At this time, if necessary, the heater 79 may be operated to supply heated air to the interior of the inner processing chamber 31. The increase in temperature of livestock manure increases the efficiency of livestock manure and further shortens the treatment time of livestock manure.

At this time, the wall portion 51 can prevent the livestock manure from occurring in the inner processing chamber 31 from directly affecting the outer processing chamber 32.

Through this process, a large amount of bubbles including methane gas is generated during the livestock manure fermentation. These bubbles are guided to the extension part 35b and are moved to the gas collection chamber 33 through the bubble distribution part 35a.

Since the processing chamber 31 is relatively high temperature and high pressure compared to the gas collection chamber 33, a large amount of bubbles generated in the inner processing chamber 31 can smoothly move to the gas collecting chamber 33 having a relatively low pressure. .

A large amount of bubbles moved to the gas collection chamber 33 is separated by the gas and solids, including the methane gas burst by the pressure difference. This solid content is moved to the outer process chamber 32 through the solid content passage part 41. Therefore, solid content collects on the inclined bottom surface of the outer process chamber 32. As shown in FIG.

Then, the solid content is delivered to the manure supply part 23 again by the solid content recovery part 61 and returned to the center part of the inner processing chamber 31.

On the other hand, the gas separated from the above-mentioned large amount of bubbles may include methane, methyl sulfide, methyl disulfide, carbon dioxide and the like.

Table 1 below is an example of measuring the amount of methane contained in the gas in the gas collection chamber 33.

TABLE 1

Measuring gas Measurand (unit: ppm) Remarks methane 72.25 Methyl sulfide 0.29 Methyl disulfide 0.229

Therefore, it can be confirmed that a large amount of methane is produced in the livestock waste treatment apparatus of the embodiment of the present invention.

Such gas is transferred to the gas separation filters 7, 9 and 11 through the gas discharge part 27 when the gas collecting chamber 33 is equal to or greater than a predetermined pressure. In particular, while gas passes through the above-described gas separation filters 7, 9 and 11, the methane gas becomes high in purity and stored in the gas tank 103. The gas stored in the gas tank 103 is burned in the boiler 105 to rotate the turbine 107. In addition, the rotational force of the turbine 107 rotates the generator 109 to produce electricity, and the produced electricity may be stored in the storage battery 111 or the like.

During the fermentation process of livestock manure for a long time, the livestock manure is completely decomposed to exist in the form of high concentration liquid in the treatment chamber. And this liquid ratio becomes high concentration by dissolving solid content.

 Subsequently, when the valve 59 is opened, the liquid ratio is moved to the liquid ratio collecting unit 53 along the pipeline and collected. Thus, the high concentration of the treated liquid can be used as compost.

Such an embodiment of the present invention can maximize the treatment efficiency of livestock manure due to the high fermentation efficiency is very fast fermentation treatment. In particular, the embodiment of the present invention can maximize the production efficiency of methane to promote the recycling of livestock manure.

In addition, the embodiment of the present invention has a fermentation process is made in a closed state to prevent odors, can be utilized as a compost of the high concentration of the liquid residue of the treated residue as an environmentally friendly advantage.
