Description

ROTARY TYPE ANAEROBIC DIGESTION APPARATUS}

The present invention relates to a rotary anaerobic digestion apparatus, and more particularly, to develop a digestive tank capacity by developing a device that rotates in an inclined state anaerobic digestion apparatus using organic materials such as livestock manure and foods as raw materials. The present invention relates to a rotary anaerobic digestion apparatus that can be flexibly applied according to site conditions and can increase the mixing efficiency of extinguishing objects in a digester.

In general, wastewater such as sewage, sewage and phosphorus, and livestock manure generated at home, livestock farms, and industrial sites contain a large amount of organic matter. Therefore, if the biological and chemical oxygen demand, suspended solids content, etc. are discharged from the wastewater containing organic matter without reaching the environmental standard, soil or water quality will be contaminated. Accordingly, the organic matter in the wastewater is discharged through a biological, physical, and chemical treatment to a stream in a purified state, thereby reducing environmental pollution.

However, the treatment effect of organic matter in the wastewater by physical methods is insufficient, and the chemical treatment requires a high treatment cost in addition to the water pollution. Therefore, recently, biological methods using microorganisms are mainly used.

At this time, most of the microorganisms used in the anaerobic digestion process is a conventional anaerobic microorganism and mixed anaerobic bacteria such as methane-forming bacteria. Anaerobic digestion is a traditional technique that has been established for some time, also known as methane fermentation.

The main purpose of the anaerobic digestion process is to recover the energy of methane at the same time as treating organic waste. In general, anaerobic digestion is divided into pretreatment process, anaerobic digestion process, gas collection and purification process, and solid resource recycling process.

To this end, the outlet 44 is preferably coupled by screwing to maintain the airtight at the other end of the discharge pipe 48 to be detachable.

Further, since the plug member 46 is conical, as shown in FIG. 1, the push valve 42 may rotate even when the stopper member 46 is in contact with the push valve 42. Alternatively, it is preferable that the bearing member 46 is installed therein so that the closure member 46 can be rotated so that the closure member 46 can be pressed even when the push valve 42 is rotated. Then, the push valve 42 is configured to open the discharge hole when pressed by the stopper member 46, and is configured to close the discharge hole while returning to its original state by the elasticity of the spring when the external force is removed, this embodiment Various types of push valves can be applied without being limited to the examples.

The operation of the discharge unit 40 may be controlled by a timer or a driving program in consideration of the internal state of the reactor 10 or the characteristics of the raw material to enable automation of operation of the reactor 10, thereby reducing an operator's management burden.

Hereinafter, the operation of the present invention will be described.

Before the raw material is reacted using the reaction tank 10, the size of the reaction tank 10 may be adjusted according to ambient conditions, conditions of the raw material, and the like. That is, the size can be adjusted by adjusting the number of each block of the reaction vessel 10 blocked by the flange.

When the size adjustment of the reaction vessel 10 is completed by the above-described process, the inclination of the reaction vessel 10 is adjusted in the state where the opening and closing port 14 and the rotary valve 42 are closed. That is, by operating the angle adjusting means 70, the angle control unit 74 to raise or lower the frame 100 by the angle adjustment driving unit 72 to adjust the inclination of the reactor (10).

When the inclination of the reaction tank 10 is adjusted in this process, the rotation driving unit 20 is operated. When the rotation drive unit 20 is operated, the reaction vessel 10 is rotated in an inclined state.

In particular, since the reaction tank 10 is supported by the rotation support means 60 is rotated stably.

Subsequently, when the raw material is introduced through the raw material input pipe 35 installed inside the fixed pipe 34 of the inlet part 30, the raw material is completely stirred by the rotation of the reaction tank 10.

At this time, the raw material is sufficiently stirred by the plurality of stirring blades 12 provided on the inner circumferential surface of the reaction tank 10. That is, since the concave stirring blades 12 are rotated together with the reaction tank 10 as shown in FIG.

In this process, the reaction of the raw material is made, and the gas generated by the reaction of the raw material is discharged to the gas collecting device through the gas discharge pipe 36 installed inside the fixed pipe 34 in parallel with the raw material input pipe 35.

Since the reaction tank 10 is rotated in a state inclined at a predetermined angle as described above, the stirring blades 12 smoothly stir the raw materials in the entire interior of the reaction tank 10.

On the other hand, when the reaction of the raw material in the reaction tank 10 is completed, a digestion liquid is generated, the extinguishing liquid is discharged through the discharge unit 40.

The discharge part 40 is configured to discharge the extinguishing liquid even if the reaction tank 10 is being rotated or in a stopped state.

That is, the stopper member 46 is advanced by operating the actuator. When the stopper member 46 moves forward to press the push valve 42, the push valve 42 is pushed while overcoming the elasticity of the spring, thereby opening the closed discharge hole.

Subsequently, when the discharge of the extinguishing liquid is completed, the actuator retracts the stopper member 46, so that the push valve 42 returns to its original state by the elasticity of the spring, thereby closing the discharge hole.

On the other hand, when the push-type valve 42 is broken or clogged, the handle-type valve 47 is closed, the discharge port 44 is removed from the discharge pipe 48, and the push-type valve 42 is maintained. As such, since the discharge pipe 48 is closed by the handle valve 47, the maintenance of the push valve 42 may be easily performed.

As described above, since the reaction tank 10 in which the raw material reacts is rotated in a state inclined at a predetermined angle, a larger amount of the raw material can be reacted, and the stirring blade 12 is provided on the inner wall of the reaction tank 10. There is no need for a separate device and power for stirring, and the stirring efficiency can be enhanced. In addition, the size of the reaction tank 10 can be arbitrarily selected so that it can be installed in various places and can accommodate various conditions.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious to those who have. Accordingly, it should be understood that such modifications or alterations should not be understood individually from the technical spirit and viewpoint of the present invention, and that modified embodiments fall within the scope of the claims of the present invention.
