A kind of highly effective sludge processing system
Technical field
The invention belongs to sludge treatment field, especially a kind of highly effective sludge processing system and its application.
Background technique
As urban economy, society and people's lives are fast-developing, kitchen garbage pacifies the pollution and public health of environment
Full harm increasingly shows, and the harm of kitchen garbage has caused the great attention of people and government.It builds kitchen garbage and handles work
Journey is the needs of rapid urban, meets the sustainable development of kitchen garbage processing, improves that kitchen garbage is innoxious, subtracts
Quantization and recycling are horizontal, and can improve the transportation of kitchen garbage.
In the prior art, sludge treating system generally comprises sludge primary dcreening operation, concentration, dosing solidification, aeration, dehydration and drying etc.
Equipment, the wherein selection of aerator play key to the quality of microbial degradation in sludge and final Treatment of Sludge effect
Effect.Such as in a kind of patent " jet stirring outlet valve " of the patent No. 201510855464.5, by the way that one is arranged in bottom
The jet agitating paddle of change realizes stirring action, however this device is not suitable for the aeration stirring process of the higher sludge of concentration,
And due to being arranged in bottom, if therefore stir peaceful space using in sludge aeration, very to the stirring action of the sludge of top half
It is limited, if adding several groups jet agitating paddle, the complexity of equipment is increased, sludge has apparent abrasion to jet agitating paddle
Effect, appearance keep equipment easy to damage and not easy to repair.In another example the patent of the patent No. 201721696495.1 " stir by gas-liquid mechanical couplings
Mix device ", by mode associated with the helix tube and agitating paddle of jet, realize agitating function, however this device needs are separately set
Motor realizes agitating paddle rotation, increases energy consumption, and equipment is complicated, matching between the rotation of the gas flow rate and agitating paddle of helix tube
Conjunction is also required to test repeatedly, is unfavorable for personnel's operation.
Summary of the invention
A kind of highly effective sludge disposal system and method for invention, can further be promoted in sludge treating system and be aerated
The aeration effect of device, is realized especially by following technical scheme.
A kind of highly effective sludge processing system, including it is sequentially connected primary dcreening operation unit, upgrading unit, solidification aeration unit, de-
Water desiccation unit;The primary dcreening operation unit includes vibrating sieving machine, air compressor machine, and the upgrading unit includes cloth mud groove, concentration basin;It is described solid
Changing aeration unit includes feed bin, charger, aeration stirring tank, and the dehydration and drying unit includes frame filter press;The aeration
Agitator tank sidewalls vertical direction is uniformly distributed several protrusions, and the protrusion includes the fluoran stream surface and lee side set up vertically, described
Fluoran stream surface and lee side are mutually perpendicular to, and plane where the lee side of each protrusion is directed to the central axes of the aeration stirring tank
Place;Vertical direction is uniformly provided with row's solarization air cap on the lee side.
Above-mentioned apparatus in the running, is full of the sludge through primary dcreening operation, concentration in aeration stirring tank, the solarization air cap of high spot sprays
High-speed air out;Under the promotion of high-speed air, sludge quick rotation in aeration stirring tank forms whirlpool, while reaching stirring
With the purpose of aeration.This device does not need to add motor or similar devices in aeration stirring tank, relies only on solarization air cap injection
High-speed air be can reach stirring aeration effect.For the sludge of various concentration, the flow velocity of penetrating air need to be only adjusted i.e.
Simple control can be achieved.
Preferably, the lee side width of the protrusion is no more than the 1/5 of the aeration stirring tank bottom radius surface.This purpose exists
In the accommodation space of saving aeration stirring tank increases the space that sludge forms whirlpool.
It is highly preferred that being equipped with fixing axle at the central axes of the aeration stirring tank, it is uniformly distributed in the fixing axle several
Turbulent flow plate.This purpose is that the sludge that the air-flow through solarization air cap pushes, the barrier effect through turbulent flow plate will be near turbulent flow plate
The turbulent flow whirlpool for forming part, realizes better aeration effect.
It is further preferred that the width of the turbulent flow plate is no more than the 1/2 of the aeration stirring tank bottom radius surface.This purpose
It is, reserves the space between protrusion and turbulent flow plate, guarantees the certain flowing velocity of sludge.
It is highly preferred that every block of the fixing axle turbulent flow plate includes several contour small turbulent flow plates being distributed vertically, phase
The gap contour with small turbulent flow plate is equipped between the adjacent small turbulent flow plate;The small turbulent flow plate of adjacent two blocks of turbulent flow plates and
Gap is staggered.This purpose is, the blocking of rotary motion of the monolith turbulent flow plate to sludge in aeration stirring tank is avoided to imitate
Fruit is too strong, leads to sludge silting;Furthermore the small turbulent flow plate being interspersed and gap, also can increase sludge agitation effect.
It is highly preferred that the turbulent flow plate and the lee side of the protrusion are on same level.This purpose is, through upper one
The sludge that the air-flow of the solarization air cap of a protrusion pushes moves to rate maximum when at the lee side of next protrusion, is arranged here
The turbulence effects of turbulent flow plate, generation are most strong, and aeration and mixing effect are best.
Compared with prior art, the beneficial effects of the present invention are:
1, since sludge concentration height needs to complete aeration stirring using pressure-air, by the aeration for just intending sludge system
The integral type of agitator tank is improved, and avoids that the devices such as aeration tube, the gas-guide tube in aeration stirring tank are excessive and each component connection
Position is excessive, causes the abrasion of air pressure loss and sludge to each component;
2, solarization air cap is located at aeration stirring pot sidewall by aeration stirring tank, and the aeration for effectively increasing the sludge of each position stirs
Effect is mixed, blind sector is reduced;
3, the effect that turbulent flow is manufactured by turbulent flow plate, further improves the effect of aeration stirring.
