Description

Recycling Ssystem of Organic Waste}

The present invention relates to a resource system for organic waste, and more specifically, to produce renewable energy from agricultural waste vinyl made from petroleum, among organic waste, to self-procure energy without additional burden of energy cost, power consumption and food waste , Waste powder sludge (livestock waste), and wastewater sludge.

Efforts to produce alternative fuel oils by pyrolyzing hydrocarbon-based organic wastes such as waste plastics, waste lubricants, waste tires, and waste vinyl have been continuously studied in response to the needs of the times.

Waste plastics that are discarded after the use of plastics have difficult decomposition properties, which are the characteristics of plastics, making landfilling difficult. When incineration, various harmful gases are discharged and pollute the atmosphere, making it difficult to treat waste plastics.

For example, when thermally decomposing waste plastics such as polyethylene, polypropylene, and polystyrene with a catalyst at a temperature condition of 400°C to 500°C, about 50w% to 70w% of the pyrolysis oil (regenerated oil) mixed with light oil and heavy oil is compared to the input amount. It is said that it can be obtained.

However, commercialization of regenerated oil is still insignificant because the quality of regenerated oil is deteriorated due to various impurities (foreign matter) generated during the pyrolysis emulsification process (level of bunker seed oil).

Impurities (foreign substances) include tar, naphtha, wax, and the like, so that the regenerated oil has a low viscosity, flash point, and a specific color or odor.

In addition, while undergoing the pyrolysis and emulsification process, as the long carbon ring of the polymer hydrocarbon is cut off and the molecules of the short carbon ring increase, the volatility of the low boiling point increases, and the viscosity and flash point are very low (if naphtha is included, the flash point is low, which is dangerous). Therefore, it is not suitable for use as a fuel for ordinary diesel burners.

On the other hand, waste plastics, waste lubricants, waste tires, waste vinyl and other hydrocarbon-based organic wastes are thermally decomposed and emulsified, and there is a problem in that recycled gas (methane is the main component) generated during the production of alternative fuel oils cannot be recycled and incinerated. .

Hereinafter, with reference to the accompanying drawings for the embodiment of the present invention will be described the configuration and operation.

It should be noted that the same components among the drawings are denoted by the same reference numerals and symbols as possible, even though they are displayed on different drawings.

In the following description of the present invention, when it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description will be omitted.

In addition, when a part is said to “include” a certain component, this means that other components may be further included instead of excluding other components, unless otherwise stated.

1 is a block diagram of a resource system according to an embodiment of the present invention, for example, for explaining the waste vinyl for agriculture as organic waste.

As shown in Figure 1, the resource system 100 according to an embodiment of the present invention, the emulsifying device 110, a reduced pressure distillation purification system 120, a diesel generator 130, a compressed gas facility 140, It is configured to include a gas boiler 150 and a disc dryer 160.

The emulsifying device 110 accommodates agricultural waste vinyl (A), such as waste vinyl, waste tires, and waste plastic, and heats it in a closed atmosphere to thermally decompose and discharges regenerated oil (B) and regenerated gas generated by thermal decomposition. .

The reduced pressure distillation purification system 120 utilizes the principle that the lower the pressure is, the lower the boiling point is. In order to obtain an oil having a high boiling point such as fuel oil (D), distillation under reduced pressure is performed under reduced pressure.

Vapors distilled under vacuum are condensed and commercialized, and the fuel obtained here is free of pollution and used as an environmentally friendly clean fuel.

When distilled and purified at low pressure and low temperature, the regenerated oil (B) does not cause thermal decomposition and can be produced as a high-quality refined oil that is stable and stored for a long period of time, and can be used as a fuel oil. In addition, by distillation at a low temperature, there is an effect of reducing heat for raising the temperature.

In addition, since it is operated at a low temperature and reduced pressure, the risk of fire and explosion is low.

The diesel generator 130 is a combination of a generator that generates electric energy and a diesel engine, and generates electric power E using fuel oil equivalent to diesel.

This power is self-consumed as the facility operating power of the resource system 100 or sold to KEPCO.

On the other hand, the regenerated gas generated by the emulsifying device 110 is purified gas (C) through the purification of offgas and compressed in a compressed gas facility 140 equipped with a compressor (CMG, Compressor Motor Governor). It is stored and reused as fuel for the gas boiler 150 described later.

The pressure regulator (CMG) does not stop the operation of the compressor when the pressure of the compressed gas facility 140 rises above a specified pressure, stops the compression operation, and causes the compression operation again when the pressure falls below a certain level. .

The gas boiler 150 produces compressed steam by burning compressed gas stored therein.

The disk dryer 160 is a type of rotary dryer that rotates as a driving means and is an indirect heat conduction method.

The disc dryer 160 is a dry treatment by drying the pig sludge (livestock waste) and sewage sludge supplied by supplying between the plurality of discs formed at regular intervals on the rotating shaft so as to rotate the steam produced by the gas boiler 150 with a rotating means. (F) is discharged.

As a result, pig-water sludge or sewage sludge having a water content of 80 to 90% becomes a dry matter (F) having a water content of 10 to 15%.

This disk driver 160 is capable of continuous operation and has less environmental load than the direct drying method because it is an indirect drying method.

FIG. 2 is a block diagram showing the treatment system of the dried matter produced by FIG. 1.

As shown in FIG. 2, it comprises a screen sorter 170, a metal sorter 180, and a microbial stirrer 190.

The dried product (F) having a water content of 10 to 15% is primarily filtered by a screen sorter 170 having a screen having a perforated network of a predetermined size.

The metal sorter 180 provides, for example, magnetic force to the dried matter that has passed through the screen sorter 170 to filter out metal foreign matter and discharges the dried material G.

The drying treatment F may be further subjected to a crushing process before being input to the screen sorter 170 or the metal sorter 180.

The dried product that has undergone the screening process is put into the microbial stirrer 190 and fermented.

At this time, in order to improve the fermentation efficiency, it is preferable to use a fermentation agent, that is, an organic fermentation microorganism (H).

As fermentation progresses, the temperature inside the fermentation increases due to the accumulation of microbial metabolism, so it must be periodically stirred during the fermentation period to remove excess heat and allow fresh air (oxygen) to enter the fermentation.

When this stirring operation is repeated, almost all of the soluble organic matter in the dried material is decomposed and composting proceeds due to the activity of microorganisms.

The dried product (G) that has undergone this fermentation process is decomposed into compost, so that pig powder sludge or other livestock waste such as organic fertilizer (I) is consumed or sold at local farms, and sewage sludge becomes a soil conditioner (J). It can be used for continuous farming and improvement of acid soil.

FIG. 3 is a diagram for explaining a function of monitoring the sensing of the resource system shown in FIG. 1.

As shown in FIG. 3, including a wireless sensor unit, a PC 230 and a DB (232,234) and a smartphone 240, a constituent unit constituting the resource system 100, for example, an emulsifying device 110 ), reduced pressure distillation purification system (120), diesel generator (130), compressed gas facility (140), gas boiler (150), disc dryer (160), screen sorter (170), metal sorter (180) and microbial stirrer ( By sensing vibration, displacement, pressure, temperature or humidity of 190), the measured data is transferred to and stored in the DB (232, 234) embedded in the PC 230, and is smartphone by a PC program acting as an M2M gateway. The monitoring app implemented in 240 accesses the PC 230 to acquire and display data stored in the DB.

The GIS DB 232 of the PC 230 stores geographic information of each constituent part of the system, and the constituent part DB stores structure and function information of each constituent part.

The wireless sensor unit includes various sensors, for example, vibration sensors 212 and strain gauge sensors 214, microcomputers 210, and CDMA modules 220a, ..., 220n through wireless communication.

The vibration sensor 212 is adjusted to measure vibration of the smallest size, and three vibration sensors are distributedly disposed in, for example, the emulsifying device 110, the gas boiler 150, or the microbial stirrer 190.

By using the low-frequency piezoelectric sensing technology of the vibration sensor 212, for example, damage to the gas boiler or the microbial stirrer of the emulsifying device can be inspected.

The strain gauge sensor 214 is attached to the structure or body part of the system to sense the degree of deformation of the system and transmits it to the PC 230 through wireless communication of the CDMA modules 220a, ..., 220n.

The M2M gateway program mounted on the PC 230 receives the sensor data transmitted from the CDMA modules 220a, ..., 220n of the wireless sensor unit from the PC, reads and removes the header of the received packet data, and then retrieves the content sensor value. It is displayed on the PC screen and converts data to be an external connection.

In addition, the vibration sensor 212 and the strain gauge 214 sensor values are individually received, and a server function is used to read the output file remotely by the smartphone 240 using Wi-Fi.

That is, the PC 230 is equipped with, for example, a WampServer application so as to perform a server function, and this Apache-based server can be easily accessed by an HTTP request, which is sensor data at a remote location. By enabling access, data can be sent and received from the remote smart phone 240 to the PC 230 via Wi-Fi.

The monitoring app installed on the smartphone 240 receives data through the PC 230 via Wi-Fi and displays sensor data or displays sensor data that changes in real time in a graph manner.

The wireless sensor unit may use a Wi-Fi + Raspberry combination that uses Wi-Fi wireless communication separately from the CDMA + Arduino combination as described above. At this time, the monitoring target may be, for example, a facility alarm, gas pressure, water level, temperature humidity, voltage current , Fire smoke, electrostatic power, counter, motor overheating, abnormal vibration, etc.

Various sensing data of each of these components are transmitted to the PC 230 through wireless communication, and the smartphone 240 can remotely manage the sensing data stored in the PC through Wi-Fi.

In FIG. 3, it has been described, for example, that the PC 230 serves as a server, but a separate system server may be constructed and a system may be implemented by providing a GIS DB or a system DB on the system server.

FIG. 4 is a diagram for explaining the NFC tagging technology of the resource system shown in FIG. 1, and an NFC tag 260 may be attached to each component constituting the resource system 100.

The NFC tag 260 is configured to store only the basic tag ID and request and receive information from the API server (ie, PC) 230 through a smartphone monitoring app based on the same.

That is, if the tag ID is read by tagging the NFC tag 260 attached to the component unit from the smartphone 240 and the tag ID HTTP is requested from the API server 230, the API server 230 may display the server DB (232,234). The information (data) of the corresponding tag ID stored in the device is read, and the component and location information (latitude and longitude) is transmitted to the smartphone 240 and output on the screen.

Accordingly, the first tagged NFC is recorded on the smartphone 240, the location of the second tag is displayed on the map, and the structures and functions of the third and fourth components are output on the screen.

In the above, the technical idea of the present invention has been described with reference to the accompanying drawings, which illustrate the preferred embodiments of the present invention by way of example, and do not limit the present invention.

In addition, it is obvious that anyone who has ordinary knowledge in this technical field can make various modifications and imitation without departing from the scope of the technical idea of the present invention.
