Detailed description of the invention
According to the content disclosed in claim of the present invention and summary of the invention, described in technical scheme of the present invention is specific as follows:
Fig. 1 is the structural representation that the present invention washes restaurant garbage treating system, Fig. 2 is the structured flowchart schematic diagram that the present invention washes restaurant garbage treating system, Fig. 3 is the structured flowchart schematic diagram that the present invention washes an embodiment of restaurant garbage treating system, refer to Fig. 1, Fig. 2, Fig. 3: the invention discloses a kind of washing restaurant garbage treating system, wherein, comprising:
One pretreatment system 101, in order to remove the organic matter in changing food waste; Before Anaerobic Treatment; material needs through pretreatment, and except rejecting the impurity protection follow-up equipment in changing food waste, larger object is the organic matter extracted as far as possible in rubbish; and anaerobic reaction is convenient in organic materials making beating, lay the first stone for more producing natural pond.
Described pretreatment system 101 in the present invention comprises the material-receiving device, a knot screen, a separating device for water with dregs, a degreasing unit and the pulverizing beating apparatus that set gradually, described material-receiving device has a feed end, described material-receiving device, described knot screen, described separating device for water with dregs, described degreasing unit, described pulverizing beating apparatus are connected by pipeline successively, and described pulverizing beating apparatus has a discharge end.
Splicing workshop in the present invention, primarily of hopper and helix transporting device composition, according to the principle of " namely producing namely clear " " operational support ", is designed to double wire system.Changing food waste, after receiving fortune vehicle transport and arriving disposal field, first arrives at the high-rise material discharging platform of pretreatment workshop, pours in hopper, then leave the theatre.Changing food waste in hopper is transported to rapidly follow-up rotary drum sieve through shaftless screw conveying device and carries out waterpower cleaning and initial gross separation.
The concrete technique effect except hetero moiety in the present invention in pretreatment system 101 is for extract organic matter to greatest extent; the coarse impurities such as removing waste tableware, metal implements, sandstone, glass or plastic containers, polybag, paper handkerchief, protect the safety of the equipment such as follow-up pulverizer, squeezer.
Pulp water in the present invention is separated can be called as street cleaner, specifically comprise: rotary drum washing and sieving machine and grit water separator, rotary drum washing and sieving machine specifically act as: changing food waste is transported to rotary drum sieve equably by shaftless screw, water in the circulation of usual employing 2 ~ 3 times, namely biochemical treatment output water temperature (35 DEG C) is heated to the hot water of (45 ~ 50 DEG C), after sieving and washing, wash out organic pollution while hogwash taste removal and most economical limit can be realized.Rotary drum washing and sieving machine is a kind of horizontally-mounted waterpower rinsing device, automatically can isolate by rinsed residue at end simultaneously.The rubbish that helical feed is come falls in rotary drum washing and sieving machine continuously, relies on the rotation of rotary drum washing and sieving machine that rubbish is stirred in rinsing liquid, reaches the object of washing.
Further, the rubbish of the large scale of construction that rotary drum filters out and sewage directly fall into the grit water separator of bottom, at this, rely on the impact of gravity, by the dynamics viscosity (magma has up to thousands of mPas) sieving and washing hot water in a large number and greatly reduce fluid, light flotation of material is to the upper strata of separator, and the heavy substance of proportion more than 1.5 is then precipitated to the bottom of separator, the relative homogeneous material in portion is mainly organic food residue in the separator, be then transferred next step process.
Further, also have one and overlap the rotary sieve of spacing 1mm separation accuracy with street cleaner supporting 2, the fluid of often overlapping the maximum 50m3/h that process street cleaner discharges and the oversize less than 7 tons/h wherein contained, target is as far as possible by organic solidity thing wherein and fluid separation applications, is convenient to oily-water seperating equipment oil removing.Rotary sieve is made up of the rotary drum filter that is rotated, in rotary drum filter, have spiral, conveying oversize.Rotary sieve diameter 1.5m, long 3m are the characteristics design of changing food waste specially.Slag-water slurry, first enters from one end of rotary sieve.Water falls into collecting pipe by the filter screen of spacing 1mm and collects, and goes out water pump by filter screen and squeeze into oil removing pot, carries out next step oil removal treatment.Slag is then slowly taken to the other end of rotary sieve by auger conveyor, fall into making beating tank there.
Oil removing part in the present invention in pretreatment system 101 is specially: the grease in changing food waste needs to extract as much as possible, this is not only only and obtains grease income, and the suppression reduced because LCFA reacts anaerobic organism, improve the task performance of anaerobic reactor.Be separated through previous step pulp water, the most of oil in changing food waste is along with the liquid inflow oil removing pot after filtration, and the oil be adsorbed in solid hogwash then enters making beating tank, because in hogwash, the content of oil is less, is can be born by AFR anaerobic reactor and be easy to digestion.Therefore mainly for the abundant Extraction and separation of bulky grain grease, and deliberately in separation means, do not employ too high energy consumption and lose more than gain.This process must be easier to realize in water-oil phase process, even if in the state of normal temperature, therefore, Gravity Separation and normal temperature oil removing are the advantages of this oil removing process process energy conservation.
Also comprise a gun barrel, in order to normal temperature separation can not carried out in special oil removing pot by the profit of screenings interference.Be equipped with slow stirrer in oil removing pot, prevent the solidity thing in profit from floating and disturb oil removing, go up cloth aluminum strip simultaneously and float to realize after particle diameter of growing up being separated for adsorbing little oil droplet.Liquid after oil removing is partly refluxed to making beating tank, and remainder branch enters system for anaerobic treatment 102(AFR water inlet tank).The tubular type oil extracting machine that gun barrel top layout is special, be for low oil-containing water form effective separate mode of oil sheet.
Pulverizing making beating in the present invention in pretreatment system 101 is specially, comparatively large through the isolated screenings volume of rotary sieve, directly enters air-flotation type anaerobic reactor (AFR) not easily digested, before Anaerobic Treatment, needs further to pulverize.Screenings first will with the liquid mixing that refluxes in oil removing pot, the material mixed will be sheared machine and grinder and pulverize, and the material after pulverizing enters system for anaerobic treatment 102(AFR and to intake tank).
The present invention also comprises cutter, and concrete technique effect is: the material through preliminary cutting enters twin shaft cutter, and cutter shears rear mixed material by < 2cm, enters grinder subsequently, to prepare more tiny material.
Further, the present invention also comprises grinder, and after leaving cutter, before entering AFR anaerobism water inlet tank, cutting accuracy is that the hogwash sheared grinds, to improve the feed conditions of anaerobic digestion by the single shaft grinder of 1mm further.
