Technical field
The present invention relates to a kind of changing food waste liquefaction mechanization process integrated apparatus.
Background technology
Along with the development of economy, people's living standard improves constantly, and in the epoch that food, non-staple food are enriched constantly, the changing food waste that kitchen residue and after the meal residue form jointly increases day by day.The changing food waste arbitrarily abandoned not only can rot smelly, grow mosquitos and flies, spread disease, and to environment, thus become the pollution sources being difficult to ignore gradually; Its process is also come into one's own day by day.
Containing large amount of organic in changing food waste, have certain value and economic worth, if be used not only can carry out harmless treatment to changing food waste, and products therefrom can also become useful product, makes changing food waste become a kind of resource.At present, on market, biochemical treatment changing food waste generally adopts from the external complete mixed Anaerobic Methods in Treating introduced, this Technical comparing is applicable to the rubbish from cooking of the high animal tallow content in west, for vegetative fiber and the starch of the higher relative facile hydrolysis of domestic content, the hydrogen base of hydrolysis easily suppresses anaerobic bacteria, causes system crash.
Domestic changing food waste is applicable to the biochemical anaerobic technology of phase-splitting, namely liquefaction process is carried out respectively with biochemical Anaerobic Treatment, controls separately.At present, biochemical anaerobic technology is very ripe, but changing food waste liquefaction process separation equipment but extremely difficulty seek, from current disclosed several treating apparatus, all there is poor processing effect, the shortcomings such as energy consumption is large.The scarcity of changing food waste liquefaction process separator seriously governs domestic changing food waste biochemical treatment development.
Summary of the invention
Object of the present invention, is to provide a kind of changing food waste liquefaction mechanization process integrated apparatus, improves changing food waste biochemical treatment efficiency.
The solution that the present invention solves its technical problem is: a kind of changing food waste liquefaction mechanization process integrated apparatus, it comprises reactor and hot device is accompanied in the heating be wrapped in outside reactor, the inner bottom part of described reactor is provided with the agitating device of the changing food waste uniform stirring in reactor, the top of reactor is also provided with and reactor is divided into reaction zone and the spoiler going out liquid zone, and described spoiler is formed in the reactor is convenient to the decanting zone that changing food waste mixture realizes Separation of Solid and Liquid.
As the further improvement of technique scheme, described spoiler is also provided with multiple inclined clapboard be parallel to each other, between adjacent inclined clapboard, forms a chute being communicated with reaction zone and going out liquid zone.
As the further improvement of technique scheme, described agitating device comprises the drive motors be placed in above reactor, the output of described drive motors is provided with shaft, is connected with the paddle being arranged on reactor bottom after described shaft passes out liquid zone, decanting zone and reaction zone successively.
As the further improvement of technique scheme, the bottom shape of described reactor is conical, and described paddle is the taper blade that the bottom shape of reactor matches.
As the further improvement of technique scheme, the sidewall of the conical lower section of described reactor is provided with charging aperture, conical lower section be provided with the slag-drip opening that can open bottom.
As the further improvement of technique scheme, described heating accompanies hot device outside to be also enclosed with muff.
As the further improvement of technique scheme, described in go out above liquid zone and be also furnished with downflow weir, described downflow weir is also provided with delivery port.
As the further improvement of technique scheme, the diameter of described decanting zone is the diameter of 1.2 ~ 2 times of reaction zones.
The invention has the beneficial effects as follows: the present invention controls the fluidised form of changing food waste in liquefying reactor by mechanical agitation, during operation, the charging aperture of changing food waste by device is evenly sent into, and be scattered in reaction zone rapidly under the effect of paddle stirring, enter liquefaction; Whole inside reactor is in the flow regime of certain rotating speed, the dissolution fluid of changing food waste post liquefaction is scattered in rapidly in water body, reduce the stripping liquid concentration around changing food waste, eliminate the impact suppressing liquefaction efficiency because stripping liquid concentration around changing food waste is higher; Spoiler is installed on reactor top, and the changing food waste slowly rotated stops operating under the barrier effect of spoiler, reduces the linear velocity of changing food waste.The decanting zone that diameter is less than reactor inside diameter reduces the upper Flow Velocity of changing food waste mixture.The movement rate of changing food waste particle reduces greatly in decanting zone, and precipitation enters reaction zone.Dissolution fluid continues upper reaches by downflow weir outflow reactor, realizes Separation of Solid and Liquid; The present invention can ensure changing food waste liquefaction and separative efficiency, process stabilization.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the present invention is further illustrated.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, describe application of the present invention in detail.
With reference to Fig. 1, a kind of changing food waste liquefaction mechanization process integrated apparatus, it comprises reactor 8 and hot device 13 is accompanied in the heating be wrapped in outside reactor 8, the hot device 13 of heating companion makes reactor 8 remain on 25 ~ 55 DEG C, the inner bottom part of described reactor 8 is provided with the agitating device of the changing food waste uniform stirring in reactor 8, the top of reactor 8 is also provided with and reactor 8 is divided into reaction zone 6 and the spoiler 5 going out liquid zone, and described spoiler 5 is formed in reactor 8 is convenient to the decanting zone 4 that changing food waste mixture realizes Separation of Solid and Liquid.
Changing food waste evenly sends into reactor 8 by charging aperture 10, is scattered in rapidly in water body, under the effect of special bacterial classification, enters liquefaction rapidly under the drive of agitating device.Fluidised form good in reactor 8 makes changing food waste be uniformly distributed at reaction zone 6, effectively improves the liquefaction efficiency of changing food waste.
Under the effect of spoiler 5, stop lateral flow after the dissolution fluid of high concentration enters decanting zone 4, augmenting response device 8 diameter reduces the vertical flowing of dissolution fluid, makes changing food waste fall to reaction zone 6 and proceeds liquefaction reaction, completes dissolution fluid and is separated.
