The present invention relates to a methane gas generation septic tank capable of generating methane gas using a septic tank installed in a general home, and in particular, a methane gas generating tank separated into a gas collection chamber and a fermentation chamber is installed at the bottom of the waste tank. The fermentation materials such as sewage and sewage fermented while passing through the methane gas generating tank are separately introduced into the purification tank and the waste tank through the level control plate and the separation filtration chamber, and only the purified water is discharged to the outside through the purification tank and the discharge chamber. On the other hand, the unfermented product introduced into the waste is re-filtered in the course of repeated circulation through the circulation passage to the separation filtration chamber, thereby increasing the generation efficiency of methane gas even under low temperature and gaseous conditions. The fermented and decomposed purification liquid can be circulated and discharged smoothly without using separate power means. It relates to a shot tank for gas.

Conventionally, a methane gas combined use septic tank capable of generating methane gas using a general household septic tank and a dedicated methane gas generator using various organic substances have been proposed and used.

However, most of the conventional methane gas purification septic tank and dedicated generator as known are fermented while generating in the sedimentation tank or fermentation tank in which the fermentation material introduced through the inlet is separated into vertical plates, etc., thereby generating gas. Liquid fermentation materials, such as sewage, have a simple flow structure to be discharged to the top through a flow path formed at the bottom of the diaphragm.

Therefore, in such a septic tank or generator, solid materials having a high specific gravity among the fermentation materials introduced into the sedimentation tank or the fermentation tank are concentrated in the bottom of the sedimentation tank or the fermentation tank. Since it has a factor of inhibiting the distribution of fermented products and gas generation, in general septic tanks, the top cover must be opened to clean the inside of the sedimentation tank at regular intervals. In the case of a dedicated gas generator, there is a separate mechanical stirring device or aeration. It is necessary to periodically stir the fermentation material introduced by installing the device inside the fermentation tank or the sedimentation tank, etc. In addition, a septic tank or generation device buried underground to prevent the generation of gas as the temperature decreases. Avoid heat insulation in the upper part of the tank or inside the upper chamber. There were difficulties in construction, such as having to install clothes.

The main object of the present invention is to provide a septic tank for methane gas generation that does not have any difficulties and problems as described above.

Another object of the present invention is to settle the fermentation tank, that is, the bottom of the methane gas generating tank, or solid fermentation material solidified in the upper portion of the fermentation material flows up and down in accordance with the change of the gas pressure filled in the upper collecting chamber and smooth distribution of the fermentation material and While it is possible to promote the fermentation efficiency, solid matter which is not fermented or decomposed during the methane generation tank is recycled to the fermentation and decomposing cycle through the separation filter room and the residue tank, and only the completely decomposed purified water goes to the outside of the septic tank. The present invention provides a septic tank for generating methane gas which can be discharged to almost complete purification.

In order to achieve the above object, the septic tank of the present invention is constructed as follows.

On one side of the rectangular cylindrical septic tank having a predetermined size, a carbon dioxide gas generating tank communicating with the inlet is separated by a vertical plate, and in the middle part, a methane gas generating tank communicating with the carbon dioxide generating tank is separated by a plate. Is installed on. The carbon dioxide generating tank is separated into an upper gas collecting chamber and a lower fermentation chamber by a horizontal filtering plate installed in the lower part, and the fermentation chamber is separated into a lower filtering plate installed in parallel between the filtering plate and the bottom surface of the tank. In addition, several guide plates having a predetermined length are alternately installed along the lengthwise direction of the tank between the lower filter plates to form a flow path through which the solid fermentation material is distributed.

In the discharge side of the tank as described above, a separation filter tank communicating with the methane gas generating tank is installed at the lower part, and a purification tank in which the purified water filtered by the filter plate of the separation filter tank is formed at the upper side thereof. It is in communication with the waste tank of the upper portion of the methane gas generating tank through the residue passage formed on one side, the circulation tank is formed on the other side of the circulation passage communicating with the separation filtration tank of the lower portion of the purification tank.

In the septic tank according to the present invention configured as described above, the methane gas generating tank is installed at the lower part of the waste tank located at the upper part of the tank, and the fermentation chamber is located at the bottom end of the generating tank by the upper and lower filtering plates. It is possible to ferment fermented materials even under low temperature weather conditions without the need for coating.

In addition, the cross fermentation material circulated between the upper and lower trapping plates of the methane gas generating tank flows up and down according to the pressure of the gas filled in the upper gas collecting chamber, so that there is no need for a separate stirring device or aeration device. The distribution is facilitated and the fermentation of the solids can be facilitated, and the non-fermented solid fermentation product is separated from the decomposed purified water during the separation filtration, enters the waste tank, and then repeats the cycle of re-fermentation and separation. Only the purified water purified through the trap plate can be discharged to the outside of the tank.

The distribution, circulation path and the effect of the fermentation product by the methane gas generation septic tank of the present invention configured as described above will be described in more detail with reference to the accompanying drawings.

As described above, the waste introduced through the inlet 2, that is, the fermentation material flows into the carbon dioxide generating tank 10, and the carbon dioxide generated while passing through the inside thereof is vented 13 above the inner partition 4. It flows into the waste tank 50 through, and then flows into the purified water tank 40 through the distribution hole (7b) of the other partition 7 and discharged through the distribution hole 61 communicated to the discharge chamber (60). The fermentation material introduced into the chamber 60 and then discharged to the outside of the tank 1 through the exhaust port 5 at the upper portion thereof, and the fermentation material introduced into the carbon dioxide gas generating tank 10 flows to the lower portion of the inner partition 4. It flows into the methane gas generating tank 20 via the sphere 4a.

The fermentation material introduced into one side of the methane gas generating tank 20 is upper and lower constituting the lower fermentation chamber 22, and part of the wastewater liquid contained in the fermentation material by the lower fermentation plates 23 and 24 is upper and lower.

The methane gas generated during the fermentation process is filled in the gas collecting chamber 21 at the upper part, and the gas collecting chamber 21 is communicated to the outside of the tank through the gas valve pipe 8 installed at the upper part. If necessary, methane gas can be used by opening a valve (not shown) installed in the gas discharge pipe 8.

In addition, the amount of gas contained in the gas collection chamber 21 is increased at any time due to the gas generation action inside the methane gas generating tank 20 and the operation of discharging the gas according to the use of the gas. As the pressure inside and outside changes, the liquid fermentation material located in the upper part of the upper trapping plate 23 flows up and down about the trapping plate 23 under the gas collecting chamber 21. As a result, since the lower portion, that is, the solid fermentation material located in the fermentation chamber 22 flows together, the solids separated according to the weight of the specific gravity of the solids are solidified at the upper portion of the fermentation chamber or concentrated at the lower portion thereof. In addition to being able to prevent the accumulation of gas, the fermentation and distribution of the gas will be facilitated.

Since the solid fermentation material passing through is gradually moved along the curved induction furnace 26 formed by each guide plate 25, it is possible to give a sufficient delay time for complete fermentation and decomposition of the undigested solid fermentation material.

The fermentation material that is decomposed through the above process and pushed out to the lower outlet side of the methane gas generating tank 20 is, as shown in FIGS. 5 and 6, the water level adjusting plate formed at the corner of the distribution port 27 ( 28) flows into the lower circulation chamber 29 in communication with the separation filtration tank 30, and the level of the fermentation material accommodated in the methane gas generating tank 20 by the level control plate 28 is kept below the proper line. In addition to the seawater, the fermentation material containing the almost completely decomposed liquid and a small amount of residues that can rise to the top of the water surface of the fermentation material is discharged to the outside of the methane gas generator 20 Will have

The pure liquid in the fermentation material introduced into the lower circulation chamber 29 through the discharge path as described above is separated into the filter plate 31 through the distribution hole 29a formed in the partition 29 '. After flowing directly into the inside or through the flow passage 29b at the lower end thereof and flowing into the lower side of the separation filtration tank 30, the liquid is passed through the flow hole 31a of the filter plate 31 and the upper chamber. (30 '), and when the internal pressure of the methane gas generating tank 20 is increased in such a state, the inflow of fermentation is continued and the level of the separating filtration tank 30 gradually increases, as shown in FIG. As described above, the decomposed liquid substance, ie, purified sewage, while remaining inside the filtration chamber 30 'is introduced into the purification tank 40 through the purification water passage 32 formed between the vertical plates 35 and 34. Debris in the lower part of the separation filtration tank (30) Contained liquid water is introduced into the cloudy reluctant tank 50 formed in the upper portion of the methane gas generating chamber 20 via the waste channel 33.

Therefore, the sewage introduced into the purification tank 40 is close to the purified water which is almost completely purified during the above-described separation filtration process, and the purified water thus purified is passed through the distribution hole 61 communicating with the discharge chamber 60. After entering the discharge chamber 60 through it is discharged to the outside of the tank (1) through the upper discharge port (3).

In addition, the liquid containing the waste introduced into the waste tank 50 is subjected to the process of being decomposed continuously while staying therein, and the part of the decomposed purified water is formed on the upper side of the partition wall 7. The dirt, which is introduced into the purification tank 40 through 7b, and is not completely decomposed, is connected to the upper circulation chamber through an outlet 7a formed on the other side of the partition 7, that is, on the opposite side of the top of the waste passage 33. (53) and then flows back to the lower portion of the separation filtration tank 30 through the flow passage 56 at the bottom thereof, followed by the separation filtration by the filter plate 31 as described above and the purification water passage (32), The purified water discharge operation through the purification tank (40) and the sedimentation passage (33) through the separation cycle through the residue tank 50 is repeatedly carried out, so that the complete decomposition of the waste and sewage discharged via the methane gas generating tank (20) And being able to separate The.
