If not properly disposed of, these organic wastes can cause immeasurable pollution to the environment.
At present, the treatment methods of organic wastes mainly include landfill method, incineration method and biological method. Among them, the main problem of the landfill method is that the secondary pollution caused by the penetrating fluid is serious, and the pollution is transferred or even aggravated to some extent; the incineration method is generally carried out at temperatures higher than 1000 ℃, and thus consumes a large amount of energy, and in addition, incineration generates a large amount of toxic gases, causing environmental damage.
The biological treatment method is a clean and environment-friendly organic waste treatment method, and organic waste is stacked in a closed fermentation device, and harmless treatment in the organic waste is realized through fermentation of microbial colonies. In order to improve the activity of the microbial colonies and improve the fermentation efficiency, a low-pressure environment is generally generated in the fermentation device through vacuum pumping.

At present, in order to realize fermentation and drying of organic wastes, a professional and fixed organic waste treatment plant is generally required to be constructed. The organic waste to be treated is transported from the generation place to the place where the organic waste treatment workshop is located for centralized treatment.
The existing organic waste treatment mode has the following obvious defects:
1. a treatment workshop with a complex structure and a large floor area needs to be built, a large number of operators are required to be arranged, and the treatment cost is high.
2. The place of the treatment plant is completely separated from the place where the organic waste is generated, and the organic waste to be treated needs to be transported to the place of the treatment plant, so that the transportation cost is high.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description thereof.
At present, in order to realize fermentation and drying of organic wastes, a professional and fixed organic waste treatment plant is generally required to be constructed. The organic waste to be treated is transported from the place where it is produced to an organic waste treatment plant for centralized treatment. It has the following obvious drawbacks: a treatment workshop with a complex structure and a large floor area needs to be built, a large number of operators are required to be arranged, and the treatment cost is high. The location of the treatment plant is completely separated from the location where the organic waste is produced, and the organic waste to be treated needs to be transported to the location of the treatment plant, which is expensive to transport.
In view of the above, the present invention is directed to a portable organic waste treatment system that can be conveniently transported to a production site of organic waste, thereby realizing on-site treatment of the organic waste.
The invention creatively arranges the functional components in the container body, thereby realizing modularization and movability. Realizations of the present invention will be described below by way of example.
Integrated organic waste treatment system convenient to move
According to an aspect of the present invention, an integrated organic waste treatment system convenient to move is provided, in which fig. 1 to 4 illustrate a structure of the integrated organic waste treatment system. As shown in fig. 1 to 4, the integrated organic waste treatment system includes a container body 200, and a fermentation drying device 1, a fermentation drying steam boiler 2 and a deodorization cooling tower 3 disposed in the container body 200, wherein:
fermentation drying device 1 includes first casing 101, is formed with the fermentation chamber in the first casing 101, is provided with feed inlet 103, discharge gate 104 and the gas outlet with the fermentation chamber intercommunication on the first casing 101, is provided with the steam circulation pipeline of keeping apart with the fermentation chamber on the inner wall of first casing 101, and first casing 101 formation first steam inlet and comdenstion water export are outwards worn out at the both ends of steam circulation pipeline. Preferably, the feeding hole 103 is formed at the top of the first housing 101, and a feeding hopper is provided on the feeding hole 103. The discharge hole 104 is provided at the bottom of the first housing 101,
the steam boiler 2 is connected to the first steam inlet via a first steam pipe 12.
The deodorization cooling tower 3 comprises a second shell, a cooling deodorization cavity is formed in the second shell, a second steam inlet communicated with the cooling deodorization cavity is formed in the second shell, the second steam inlet is connected with the gas outlet of the fermentation drying device 1 through a second steam pipe 13, and a vacuum pump 5 is connected to the second steam pipe 13.
As an example, the integrated organic waste treatment system of the embodiment of the present invention treats organic waste as follows:
the integrated organic waste treatment system of the embodiment of the invention is transported to a production place of organic waste to be treated.
And starting the steam boiler 2, feeding high-temperature steam generated in the steam boiler 2 into a steam circulation pipeline in the fermentation drying device 1 through a first steam inlet, and flowing along the steam circulation pipeline, wherein the high-temperature steam and the fermentation drying device 1 generate heat exchange in the process, so that the fermentation drying device 1 is preheated. The purpose of preheating is to activate the microorganism bacteria preset in the fermentation chamber, and the preheating time is generally 20 to 40 minutes. The high-temperature steam after heat exchange finally flows out of the steam circulating pipeline through a condensed water outlet.
After the preheating is completed, the feed inlet 103 is opened, and the organic waste to be treated is fed into the fermentation chamber of the fermentation drying device 1 through the feed inlet 103. Optionally, in order to improve the fermentation effect, a larger amount of microorganism bacteria may be put into the fermentation chamber through the feeding hole 103 along with the organic waste to be treated. Alternatively, the organic waste to be treated may be fed to the fermentation drying apparatus 1 by means of a feed screw conveyor 7.
After the organic waste is put in, the feeding 103 is closed, and the microorganism bacteria begin to ferment and decompose the organic waste. Meanwhile, due to the heating of the organic waste by the steam boiler 2, liquid components such as water, oil and the like in the organic waste and certain organic components which are easy to volatilize are converted into mixed steam and separated from the organic waste. With the continuous fermentation, the humidity of the organic waste is continuously reduced, the content of organic components in the organic waste is also continuously reduced, and finally the organic waste is completely decomposed and removed.
The fermentative decomposition is completed after a predetermined period of time (e.g., 1 to 2 hours). After the fermentation is finished, the vacuum pump 5 is started, the air pressure in the fermentation cavity is continuously reduced, and finally a negative pressure environment is formed. Under the negative pressure environment, the boiling point of liquid components such as water, oil and the like in the organic waste is increased, so that the drying speed of the organic waste is accelerated. Further, the mixed steam in the fermentation chamber is drawn into the deodorizing cooling tower 3 through the first steam pipe 12 by the driving of the vacuum pump 5. The deodorization cooling tower 3 realizes the cooling and condensation of the mixed steam.
Because the organic components in the organic waste are basically decomposed and removed after the full fermentation of the microbial bacteria, the mixed steam in the fermentation cavity is clean high-temperature steam, and the high-temperature steam can be directly discharged or recycled after being pumped into the odor cooling tower 3 for condensation.
Of course, in order to further improve the cleanliness of the mixed steam, deodorizing microorganisms may be pre-placed in the deodorizing cooling tower 3 to completely remove a trace amount of odor components remaining in the mixed steam.
The dried material after fermentation and drying is finally discharged out of the fermentation drying device 1 through a discharge port 104. Optionally, the dried material is drawn off the fermentation chamber via a discharge auger 8 connected to the discharge opening 104.
According to the specific type of the dry materials, corresponding recovery processing can be realized. For example, dry materials produced by human and animal excreta can be recovered as fertilizer, and the kitchen can be recovered as feed.
It can be seen that in the integrated organic waste treatment system according to the embodiment of the present invention, the fermentation drying device 1, the steam boiler 2, the deodorization cooling tower 3, and other functional components are integrated and disposed in the same container, which can be conveniently transported to different organic waste production sites to implement on-site treatment of organic waste, thereby significantly reducing the treatment cost of organic waste.

If the functional components are clamped and fixed on the corresponding mounting platforms by the clamping pieces, the clamping pieces are arranged on the mounting platforms.

Optionally, operation windows are disposed at positions of the container body 200 corresponding to the feed inlet 103 and the discharge outlet 104, and of course, an openable cover or a door may be disposed on the operation windows.

The condensed water having completed the heat exchange finally flows back into the deodorizing cooling tower 3 through the second cooling water pipe 15 and is cooled by the deodorizing cooling tower 3, thereby forming a closed cooling circulation circuit.

Similarly, in order to supply power to each functional component, the assembled organic waste treatment system of the present embodiment is also provided with a solar photovoltaic power generation apparatus 18 mounted on the top of the first container 300 or the second container 400. Of course, a set of independent foldable solar power generation devices 18 may be provided on the top of the first container 300 and the second container 400, respectively. The structure of the folding solar power generation device 18 is completely the same as that of the folding solar power generation device 18 in the integrated organic waste treatment system in the previous embodiment, and the detailed description thereof is omitted.
Finally, it should be noted that, without being contradictory, various alternative and preferred embodiments of the container body and the functional components of the organic waste treatment system according to the above embodiments of the present invention may be referred to each other.
Application example
As shown in the foregoing, in the organic waste fermentation drying system of the present invention, the fermentation chamber is heated by steam and vacuumized, so that the organic waste is fermented and dried in a high-temperature and low-pressure environment. Under high-temperature and low-pressure environment, liquid components such as water, oil and the like in the organic waste can be quickly distilled out. In addition, the activity of the microorganism bacteria is further improved under the high-temperature and low-pressure environment, so that the fermentation effect is better.
The organic waste fermentation drying system can realize harmless treatment on almost all kinds of organic wastes. The organic waste to be treated is directly put into the fermentation cavity for treatment without pre-dehydration and pre-deoiling. For example:
1. innocent treatment of sludge
The water content of the sludge is large, and the traditional fermentation can not realize the harmlessness and drying of the sludge, so that in the prior art, the humidity of the sludge is generally required to be reduced in advance by a solid-liquid separation technology before the sludge is subjected to fermentation treatment. The organic waste fermentation drying system can realize rapid fermentation and drying of sludge, and realize sludge reduction, harmlessness and recycling in a real sense.
2. Harmless treatment of human and animal excrement
Human and animal excreta contain a large amount of pathogens, and the traditional fermentation treatment cannot kill the pathogens. Therefore, in the prior art, before the fermentation treatment of human and animal excreta, a medicament is generally required to be added to kill pathogens. The addition of the medicament to kill pathogens not only increases the treatment cost, but also may cause secondary pollution. The organic waste fermentation drying system can realize high-temperature steam heating of human and animal excreta, thereby realizing killing of pathogens.
3. Harmless treatment of oil organic waste
Oil organic waste or soil polluted by oil pollutants generated by chemical plants has high oil content. The natural activity of the microorganism bacteria in the organic waste is low, so that the traditional fermentation is difficult to realize the harmless treatment of the organic waste. The organic waste fermentation drying system can improve the activity of the microorganism bacteria, thereby realizing the rapid fermentation and drying of the oil organic waste.
The invention has been described above with a certain degree of particularity. It will be understood by those of ordinary skill in the art that the description of the embodiments is merely exemplary and that all changes that come within the true spirit and scope of the invention are desired to be protected. The scope of the invention is defined by the appended claims rather than by the foregoing description of the embodiments.
