The present invention relates to a methanation treatment device, which handles dirt such as rice produced in a hospital, a hotel, a restaurant, human manure at a group residence, postpartum treatment at a hospital's obstetrics and gynecology, and livestock-related livestock. It relates to an alternative energy combined methanation treatment system that generates methane gas as a by-product during the treatment.

In general, methane fermentation is not generated by heating itself, but is produced by applying heat from the outside, and it is generally known that fermentation is most active at about 35 ° C to 40 ° C.

The gas generation process in fermentation shows that the basic basic bacteria are active in the organic materials containing carbohydrates, proteins, fats, and fibrin, and the macromolecular organics are liquefied into low molecular organics containing amino acid peptides, fatty acid glycerin, and monosaccharides. The main bacteria are mainly swelled and replaced with organic acids such as low acid, propionic acid, acetic acid lower fatty acid, etc., having low braille molecular weight. At this time, methane bacteria are active to decompose fatty acids, generating gases such as methane, carbon dioxide, and hydrogen sulfide.

By using this principle, a methane gas generating device using manure as a medium has been developed. However, in order to generate methane gas as a conventional device, it is essential to heat the manure storage tank at about 35 ° C to 40 ° C. In addition, this caused not only problems in the installation of tanks, but also a lot of troublesome replacement of the manure that was injected because new manure should be injected when the generation of methane gas stopped.

In addition, there are devices designed to ferment methane gas into livestock such as compost or livestock without the use of electrical devices or chemical reactions in rural areas. However, these devices also have the disadvantage of maintaining an appropriate temperature. There was a problem. In recent years, such methane fermentation technology has been actively researched to allow liquefaction and gasification to proceed in the same tank, but the situation and implementation thereof still have problems.

Therefore, the present invention is designed to compensate for the above-mentioned disadvantages, and as described above, it is not only responsible for the purification of the surrounding environment by treating soil such as rice or manure, but also means for heating in the accompanying process. It is an object of the present invention to provide a multi-purpose ethane treatment apparatus that can use alternative energy devices that ferment methane gas as it is and use it as an energy source without using it.

In addition, according to the present invention, the methanation treatment apparatus has an acidic fermentation portion (liquefaction), an acid lowering portion that promotes gasification therefrom, and an alkaline fermentation portion of the treatment process, which are divided into separate frames, and are stored in the same structure. It is characterized by an underground type that can expose only the entrance and bury it underground.

In addition, according to the present invention, when the methane fermentation is stopped in the conventional apparatus, it is possible to continuously input the gas injection and the new injection without having to replace the gas injection, and the gas injection must be naturally extinguished.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

In the drawing, (1) is a tank of the methanation treatment apparatus according to the present invention, which is composed of an inlet (2), an acid fermentation unit (3), an acid lowering unit (4) and an alkaline fermentation unit (5). As a special steel, special steel may be used. (12) and (13) are diaphragms which distinguish the acid fermentation section 3, the acid lowering section 4, and the alkaline fermentation section 5, respectively. (6) is a discharge pipe in which the mixed gas generated in the alkaline fermentation unit (5) is discharged by water pressure, and the valve (9) and the outlet (10) after the deodorizer 7 filters out gas other than methane gas to remove odors. It is connected to gas equipment through). (11) represents the basement.

First, when raw materials such as rice and manure are introduced into the inlet 12 of the tank 1 according to the present invention, the acid fermentation and liquefaction process is started in the acid fermentation unit 3 in one step.

In this process, complex organics are usually soluble and decomposed into substances having low molecular weight by basic bacteria. At this time, the diaphragm 12 is used to promote the reaction in the acidic fermentation (3). After this process, the methane fermentation and gasification process is started in the acid lowering (4). At this time, the methane bacteria are active to decompose fatty acids, so that gasification is induced, and the gas generated through the weakly-calibrated fermentation unit 5 is discharged. In addition to the methane gas, such gas is mixed with carbon dioxide, emulsified gas, etc., will cause a bad odor. Therefore, the degasser 7 separates and collects various gases other than methane gas, and uses them for other purposes, and the methane gas filtered therefrom is used as an energy source.

In the present invention, a reliable methanation gas treatment is assured by allowing the conventional tank to be divided into the diaphragms 12 and 13 to operate each reaction process independently.

In addition, there is no need to install a separate heating device because it does not need to be heated, so the facility is simple and becomes a semi-permanent device in a single construction. This permanence is that the raw material is digested into the liquid after each step, so it is necessary to use the principle of the general septic tank, so it is not necessary to replace the raw material separately.

As described above, when the device according to the present invention is installed in a school, a hospital, a hotel, or a large building, it can also play a role as an energy substitute using waste resources along with waste disposal, and thus its utility value is very practical. .
