The body 10 maintains a vacuum inside. Due to the vacuum state inside the body 10, sterilization of the entered liquid dirt can be facilitated.

The body 10 includes an inlet 11, first and second outlets 13 and 15, and a door 17. The inlet 11 is purged of liquid dirt for sterilization. The inlet 11 may be provided at a lower side of the body 10.

The first outlet 13 discharges water separated from the incoming liquid dirt. The first outlet 13 may be provided in the middle portion of the side surface of the body 10 because water and sludge separated therefrom are precipitated in the lower portion and water vapor and gas are formed in the upper portion. The first outlet 13 is connected to the purified water tank 300 described below, and the moisture that is sterilized and discharged from the sterilized tablet tank 200 is collected in the purified water tank 300.

The second outlet 15 discharges the gas separated from the incoming liquid dirt. For discharging the gas, the second outlet 15 may be provided at the top of the body 10, that is, at the top of the triangular pyramid. The gas discharged to the second outlet 15 may again be introduced into another apparatus for sterilization treatment.

The door (17) is installed on the upper part of the body (10) in the form of a triangular pyramid. According to the shape of the door 17, water vapor evaporated by the synergistic action in the body 10 flows down on the ceiling portion of the door 17 and is naturally discharged to the first discharge port 13. The door 17 is opened and closed by being connected to a hydraulic cylinder (not shown). When the door 17 is opened, that is, when the door 17 is opened to collect the solid sludge in the body 10, the operator can get into the body 10 and collect the sludge easily . When the door 17 is closed, the inside of the body 10 is sealed to maintain the vacuum state. That is, the door 17 is packed with the body 10, so that the vacuum inside the body 10 can be maintained.

The float switch 20 is provided inside the body 10. The float switch 20 checks the level of the liquid dirt introduced into the body 10. And checks the level of the liquid dirt inside the body 10 preset by the operator through the float switch 20. [ By checking the water level through the float switch 20, it is possible to determine whether the sterilization treatment is continued or whether more liquid dirt for sterilization is to be introduced. That is, the float switch 20 is connected to the first blanket valve 30 described below. When the level of the liquid dirt is lowered by the float switch 20, for example, 80%, the first blanket valve 30 is operated So that the sterilized liquid dirt is further flowed into the inlet 11 to be 100%.

The first blanket valve (30) is provided at the top of the body (10). As described above, when the float switch 20 judges that the level of the liquid dirt is reduced, the first ventilvalve 30 is opened so that the sterilized liquid dirt is further introduced into the inlet 11. The first ventilated valve 30 allows the generated gas to be discharged to the second outlet 15.

The moisture sensor 40 is provided in the lower part inside the body 10. The moisture sensor 40 separates moisture and checks the remaining moisture of the sludge settled in the lower portion of the body 10. [ When the moisture of the sludge is completely dried through the moisture sensor 40, the time when the sludge settled in the body 10 is discharged is reported.

The hot water pipe 60 is formed so as to surround the body 10, for example, the lower portion of the body 10. Hot water flows into the hot water pipe 60, and the temperature inside the body 10 is kept constant at about 50 to 60 degrees due to the hot water. This temperature accelerates the evaporation of water in which the incoming liquid dirt becomes water vapor. As a result, various bacteria and microorganisms remaining in the liquid dirt are wiped off, and separation of water and sludge is promoted.

And because of constant temperature maintenance, fermentation and various decomposition functions are stopped, and the major part of the odor is accelerated and the odor is removed. The malodor is caused by propagation in the process of oxidizing nitrate nitrogen which is a nitrogen compound generated by decomposition of protein. It kills bacteria and microorganisms existing in nitrogen compound to prevent the generation of odor, It is not possible to reproduce itself because there is no oxygen.

In addition, the water mixed in the liquid dirt is induced to evaporate, and various harmful components mixed therein are separated from moisture and are annihilated, so that distilled water can be obtained. When this moisture evaporates, only the dried sludge remains as a dry solid.

Also, the use of electricity is minimized to maintain the temperature for evaporation of steam, thereby maximizing the energy efficiency.
