Followed by emission-control equipment 81, the second blower 82.
Fig. 3 to Fig. 8 is a kind of specific embodiment of kitchen fruits and vegetables treating method for organic refuse of the present invention, below in conjunction with this hair
Bright included system is illustrated, and a kind of kitchen fruits and vegetables organic garbage treatment system includes sequentially arranging according to process flow,
Primary election platform 2 with elevator 1, the broken dewaterer 4 with panel conveyer 3 further include solids management system 5, waste water
Processing system 6, heat energy circulating system 7 and exhaust treatment system 8；Solids management system 5 and waste water treatment system 6 respectively with it is broken
Dewaterer 4 connects, and heat energy circulating system 7 and solids management system 5 connect, exhaust treatment system 8 respectively with heat energy circulating system 7
It is connected with waste water treatment system 6.Compared with the existing technology, the present invention increases secondary sorting platform in solids management system 5,
Processed product is set to be easier to store and transport；It joined waste water treatment system 6 after broken dewaterer 4, to kitchen fruit
The moisture of vegetable rubbish separation is further processed, and reduces contaminated wastewater discharge；Heat circulation is added between solids management system 5
System 7, recycling heat energy, and heat energy circulating system 7 is generated into exhaust gas and accesses exhaust treatment system 8, make entire production technology
Waste water, solid, exhaust gas rubbish in process can be recovered and recycle.
As shown in figure 4, in a particular embodiment, the boosted machine 1 of kitchen fruits and vegetables rubbish, primary election platform 2, panel conveyer 3,
After broken dewaterer 4, solid refuse enters solids management system 5, and solids management system 5 includes setting gradually according to process flow
First screw conveyor 51 makes fertile machine 52, conveyer 53, the second screw conveyor 54, secondary sorting platform 55, granulator 56.
Wherein, the first screw conveyor 51, conveyer 53 and the second screw conveyor 54 are used to solid transportation, make fertile machine 52 using existing
There is the organic materials fertilizer machine met the requirements in technology or patent document, makes fertile machine 52 and be used for the pairs of ring of organic matter fast transition
The harmless biological organic fertilizer in border, and made fertile machine 52 and be discharged, biological organic fertilizer is sent into secondary sorting platform 55 with conveyer belt, is sieving
After dividing bulk sundries, into granulator 56, the pellet of certain specification is made, most transports through storing vehicle to material library, is packaged afterwards
After be sold to various regions for agricultural planting and planting technique.
As shown in figure 5, the heat energy circulating system 6 includes the first blower 61 and heat exchanger 62, there are two the tools of heat exchanger 62
Gas outlet and two air inlets, 62 air inlet of heat exchanger are separately connected the first blower 61 by gas-guide tube and make fertile machine 52, heat exchanger
62 gas outlets are separately connected the fertile machine 52 of system and exhaust treatment system 7 by gas-guide tube.It is higher due to may require that when making the fertile work of machine 52
Temperature, for the waste for avoiding thermal energy, heat exchanger 62 is arranged gas-guide tube in the inlet for making fertile machine 52 and imports height to fertile machine 52 is made
Cryogenic gas is imported heat exchanger 62 in the exit setting gas-guide tube for making fertile machine 52 by wet body.The connection of heat exchanger 62 simultaneously the
One blower 61 guarantees lasting heat supply of the high-temperature gas to fertile machine 52 is made；Heat exchanger 62 is also connected with exhaust treatment system 7, with processing
The exhaust gas that heat exchanger 62 generates.The gas temperature for importing the fertile machine 52 of system must be produced at 60 degrees Celsius or more with making in fertile machine 52
Raw gas-vapor mix will make aqueous vapor and volatile organic matter that fertile machine 52 generates and take away from fertile machine 52 is made, reach dry materials and
The double effects of oxygenation.
As shown in fig. 6, the waste water treatment system 7 includes by the sequentially connected wastewater disposal basin 71 of aqueduct, folded spiral shell machine 72, detests
Oxygen reactor 73, air blower 74, aerobic reactor 75, level-one stereoscopic purification device 76, second level stereoscopic purification device 77.Kitchen fruit
Vegetable rubbish can generate a certain amount of waste water through broken dewaterer 4, and discharge of wastewater is useless by flowing into after water-oil separating via oil-isolating device
Folded spiral shell machine 72 is squeezed into pump in pond 71, suspended material not soluble in water is further compressed separation, the sludge of extrusion is sent into system fertilizer
Machine 52 makes fertile processing, and compression waste water enters efficient biochemical reactor, combines biochemistry through anaerobic reactor 73 and aerobic reactor 75
Processing flows into plant purification device after removing majority of organic pollutants certainly, the low concentration in waste water is difficult to resolve organic matter into one
Step purification.High-efficiency plant can be by pollutants high-efficient purifications such as ammonia nitrogen, phosphate in waste water, so that waste water energy is directly used in greening
With water or ground flushing water, so that water resource is also fully used.In a particular embodiment, select Chinese celery as efficiently plant
Object purifies waste water.Plant purification device includes level-one stereoscopic purification device 76 and second level stereoscopic purification device 77.
As shown in fig. 7, the exhaust treatment system 8 includes emission-control equipment 81 and the second blower 82, at the exhaust gas
It manages device 81 and heat exchanger 62 is connected by gas-guide tube, level-one stereoscopic purification device 76 is separately connected by aqueduct and second level is three-dimensional
Purification device 77.By being sprayed to the exhaust gas in emission-control equipment 81, photodissociation, qualified discharge after active carbon adsorption.It follows
The ring spray water drenching recycled water up to standard from wastewater treatment will directly be sprayed from level-one stereoscopic purification device 76 is flowed into after spraying
The organic matter to get off carries out circulating purification, does not need external water source and does not also need addition drug, less useless with periodic replacement spray
Water, operational administrative are easy.
In the present invention, it should be noted that during solids treatment, the technical principle for making fertile machine 52 is to utilize high temperature
Solid-fermented technique makes its fermentation temperature steadily in the long term at 60 degree or so；During recycle heat, heat exchanger 62 is to utilize
The cold air for making hot waste gas and air inlet that fertile machine 52 is discharged is carried out heat by efficient gas-gas heat exchanger 62 by the principle of heat exchange
Exchange, makes heatrejection decline to a great extent, and inlet air temperature rises, and can greatly reduce air heating energy consumption in this way；In wastewater treatment
In the process, it is combined using anaerobic reactor 73 and aerobic reactor 75, using high purity oxygen gas, the volume of gas needed for reducing；It plants
Object purification device is a kind of more mature sewage disposal technology, wherein most widely used is exactly Artificial Wetland Techniques.
In a particular embodiment, the present invention relates to three cyclic processes；First is that the sky between heat exchanger 62 and the fertile machine 52 of system
Gas recycle heat；Second is that the water circulation between anaerobic reactor 73 and aerobic reactor 75 and wastewater disposal basin 71；Third is that level-one is vertical
Shower water circulation between body purification device 76 and second level stereoscopic purification device 77 and emission-control equipment 81.
