Description

[0001] ELECTRICITY GENERATION [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electricity generating device capable of generating biogas generated by fermenting livestock manure, organic wastes and the like into electricity.

In general, organic wastes such as livestock manure can be treated by anaerobic digestion through several digesters.

Anaerobic digestion is an anaerobic microorganism that takes up organic matter in the sludge, decomposes by reduction, and releases inorganic compounds.

Such anaerobic digestion can not only reduce the amount of sludge but also produce methane gas, so that useful resources can be obtained from organic waste such as livestock manure.

However, in the conventional electric power generating apparatus using livestock manure, there is no means for controlling the feeding path of the raw water for digestion for digesting organic wastes. Therefore, if any one of the digestion vessels has a failure, There is a problem in that the digester needs to be repaired after the operation of the digester is stopped.

The fermenter may be arranged so that two or more fermentors are spaced apart from each other.

In the present invention, the number of the fermentation tanks is not limited, and two fermentation tanks (first fermentation tank 10 and second fermentation tank 20) are shown.

The first fermentation tank (10) and the second fermentation tank (20) each have an opening formed on the upper surface thereof and a tank structure having an empty space formed therein.

The opened portions of the first and second fermentation tanks (10, 20) are sealed by gas pockets (11, 21).

In one example, a plurality of frameworks (not shown) formed in a curved shape are provided on the upper side of the first fermentation tank 10 and the second fermentation tank 20, and the opening is sealed by covering the frame with the gas gun , It is possible to prevent the gas and odor generated in the inner space of the first fermentation tank (10) and the second fermentation tank (20) from leaking to the outside.

Meanwhile, the fermentation product and the raw water for fermentation are stored in the inner spaces of the first and second fermentation tanks (10, 20).

At this time, the fermented product may be used to produce biogas such as livestock manure, and the raw water for fermentation may be wastewater.

In addition, since the fermentation period varies depending on the size of the fermented product, the inner space area of the first fermentation tank 10 has an area smaller than the inner space area of the second fermentation tank 20.

Therefore, the fermented product having a predetermined size or less may be fermented through the first fermentation tank 10, and the fermented product having a predetermined size or more may be fermented directly through the second fermentation tank 20.

The inner space area of the post-fermenter (30) is smaller than the inner space area of the second fermenter (20).

Therefore, the fermented product having a smaller size than that of the fermented product to be fed into the second fermentation tank 20 may be directly fed into the post-fermentation tank 30 and fermented.

The electricity generating device 1 according to the present invention is characterized in that the fermented material fermented in the first fermentation tank 10 is transferred to the second fermentation tank 20 to be fermented secondarily and then transferred to the post- It is also possible to ferment by car, which will be described in detail later with the control unit 50.

In addition, since the frame 541 is spaced apart, a sliding groove 54a through which the opening and closing part slides is automatically formed therebetween.

The upper ends of the transfer tubes 51a and 51c are respectively inserted into the bottom surface of the connector 52a positioned between the first and second fermentation tanks 10 and 20, The upper ends of the transfer tubes 51b and 51e are respectively inserted into the bottom surface of the connector 52b positioned between the second fermentation tank 20 and the post-fermentation tank 30, The upper ends of the conveyance pipes 51d and 51f are respectively inserted through the bottom surface of the connector 52c positioned between the upper and lower ends of the connector 52c.

Therefore, raw water for fermentation emulsified in the first fermentation tank 10 and the fermented material mixed therein are lifted through the transfer pipe 51a to be transferred to the inside of the connector 52a, and then transferred to the second fermentation tank 20, and is transferred to the inside of the second fermentation tank 20.

The raw water for fermentation emulsified in the second fermentation tank 20 and the fermented product mixed therein are lifted through the transfer pipe 51d to be transferred into the connector 52c, And then is transferred to the inside of the post-fermentation tank 30. The post-

The opening and closing unit 53 opens or closes a space between the transfer pipes 51a and 51c, between the transfer pipes 51b and 51e and between the transfer pipes 51d and 51f in the internal spaces of the connectors 52a, 52b and 52c, And controlling the transfer of the mixed fermentation product thereto.

For example, when the opening / closing part 53 is coupled to the sliding groove 54a of the rail part 54 in the control part 50 located between the first fermentation tank 10 and the second fermentation tank 20, the opening / closing part 53 And the opposite ends are in close contact with the inner wall surface of the connector 52a to close the space between the transfer tubes 51a and 51c while the lower ends of the rail portions 51a and 51c are in close contact with the bottom surface of the connector 52a, The space between the transfer tubes 51a and 51c is opened.

The gas generated in the first fermentation tank 10, the second fermentation tank 20 and the subsequent tank is stored in the storage unit 80 and the power generation unit 60 stores the gas stored in the storage unit 80 It collects and burns to produce electricity.

At this time, the power generation unit 60 can generate electricity by burning the gas stored in the storage unit 80 to drive the engine.

The power generation unit 60 may be applied to a generator that converts an existing diesel fuel engine to a gas fuel engine.

The generator is a generator for a biogas, and has an efficiency of about 40 to 45%, and is provided with an engine for a generator capable of generating electricity using LPG, LNG, and biogas (Biogas) The noise level is 50 dB at a distance of 1 dB, and a self-soundproofing device is provided.

Next, the operation of the electric power generating device 1 according to the present invention and the unique effects appearing in the process will be described.

The first fermentation tank 10, the second fermentation tank 20 and the post-fermentation tank 30 are supplied with raw water for fermentation and fermented products of different sizes. The fermented product and the raw water for fermentation are supplied to the first fermentation tank 10, Fermented.

And, during the fermentation process, gas is generated and the generator collects the generated gas to produce electric power.

When the amount of the fermentation product equal to or greater than a predetermined amount is mixed with the fermentation raw water in the first fermentation tank 10, the fermentation product and the fermentation raw water are transferred through the transfer pipe 51a.

The fermented product and the fermentation raw water transferred through the transfer pipe 51a flow between the lower part 54 of the connector 52a and fall through the transfer pipe 51c to be supplied to the second fermenter 20 Respectively.

When the fermentation product and the fermentation raw water are mixed with each other in the second fermentation tank 20, the fermentation product and the fermentation raw water are transferred again through the transfer pipe 51d.

The fermented product and the fermentation raw water transferred through the transfer pipe 51d flow between the rails 54 on the bottom surface of the connector 52c and fall down through the transfer pipe 51f, .

At this time, the electricity generating device 1 according to the present invention can selectively control the transfer of the fermentation product and the raw water for fermentation.

For example, when the fermented product of the first fermentation tank 10 and the raw water for fermentation are to be directly transferred to the post-fermentation tank 30 without passing through the second fermentation tank 20, The opening and closing part 53 is removed from the rail part 54 of the connector 52b provided between the fermentation tank 30 and the connector 50b provided between the first and second fermentation tanks 10, The first fermentation tank 10 and the second fermentation tank 10 may be emulsified in the first fermentation tank 10 by closing the space between the transfer tubes 51a and 51c by providing an opening / The raw water for fermentation and the fermented product which have been brought to the bottom surface of the connector 52a positioned between the two pipes 20 and 20 are not flowed to the transfer pipe 51c by the opening and closing part 53 and become high on one side.

Therefore, the fermentation product of the first fermentation tank (10) and the raw water for fermentation are transferred only to the post-fermentation tank (30).

The opening and closing part 53 of the control part 50 connecting the second fermentation tank 20 and the post-fermentation tank 30 is not in a state of closing the inside of the connector 52c, The fermented product and raw water for fermentation are emulsified and transferred to the post-fermentation tank (30).

Furthermore, in the conventional case, for example, when the inside of the second fermentation tank 20 is to be cleaned, or when the stirrer and the fermentation equipment in the second fermentation tank 20 are abnormally damaged to repair the fermentation product, And the first fermentation tank 10 must also be shut down to prevent the raw water for fermentation from being emulsified in the second fermentation tank 20, 1 can selectively control the emulsification transfer of the fermentation product and the fermentation raw water through the control unit 50 so that even if the second fermentation tank 20 is stopped for cleaning or repairing, ) And the fermentation unit can be normally fermented in the second fermentation tank, so that there is no possibility that the gas generation and the power production operation are interrupted.

In another example, when the fermented product of the first fermentation tank 10 and the raw water for fermentation are to be transferred only to the second fermentation tank 20 without being transferred to the post-fermentation tank 30, 2 of the connector 52b provided between the first fermentation tank 10 and the post-fermentation tank 30 after removing the opening and closing part 53 from the rail part 54 of the connector 52a provided between the two fermentation tanks 20, An opening and closing part 53 is provided in the rail part 54 of the connector 52c provided between the rail part 54, the second fermentation tank 20 and the post-fermentation tank 30, The space between the first fermentation tank 10 and the second fermentation tank 20 is closed so that the fermentation raw water that has been emulsified in the first fermentation tank 10 and brought to the bottom surface of the connector 52a positioned between the first and second fermentation tanks 10, And the fermentation product can not flow to the transfer pipes 51e and 51f by the opening and closing part 53, and become high on one side.

Therefore, the fermented product of the first fermentation tank (10) and the raw water for fermentation are transferred only to the second fermentation tank (20).

The post-fermentation tank 30 is connected to the liquid-feed tank 90 through a pipe to transfer the fermented product and the raw water for fermentation in the post-fermentation tank 30 to the liquid-feed tank 90, The inside of the agitator 30 or the agitator and the fermentation apparatus may be repaired.

The electricity generating device 1 according to the present invention is capable of stopping the operation of the first fermentation tank 10 and generating the gas only in the second fermentation tank 20 and the post-fermentation tank 30 through the features of the above- The feed path of the fermentation product and the raw water for fermentation can be selectively and freely adjusted by feeding the fermented product of the second fermentation tank 20 and the raw water for fermentation in the order of the first fermentation tank 10 and the post-fermentation tank 30 Do.
