Abstract
The utility model discloses a small-resistance-base even water distributor for a UASB (upflow anaerobic sludge blanket). The water distributor comprises a round water distribution plate arranged at the upper part of a reversed-cone-shaped container, an opening at the lower part of the reversed-cone-shaped container is a water inlet, three layers of pebble layers made of pebbles with different grain diameters are further paved on the water distribution plate, water outlet holes of the water distribution plate are all arranged on a series of gradually dense concentric circles from the center to the periphery of the circle, and the number of the water outlet holes on the concentric circles is in a direct proportion relation with the diameters of the concentric circles. The water distributor can distribute water evenly and prevent blockage, in addition, the impact force of the water flow is appropriate, so that the damage to the biological microenvironment is reduced.
Description
Technical field
The utility model relates to technical field of waste water processing, is specifically related to a kind of UASB substrate slight drag even water distributor.
Background technology
Anaerobic reactor is in current wastewater treatment, to apply commonplace a kind of device, wherein UASB(up-flow anaerobic sludge blanket) application more extensive.Water distributor is a key part of this reactor, and it has the function of water distribution and stirring, and is determining the water intake mode of reactor, affects reactor beds laminar flow regime, relates to the interphase mass transfer in reactor beds.Therefore the quality of water distributor structure is directly connected to the volume usefulness of reactor.Traditional water-distributing device is mainly divided into tabular water distributor, ring-type water distributor and spiral water distributor three major types by its structure.
The major advantage of tabular water distributor is: 1. simple in structure, save material; 2. hydraulic resistance is relatively little.Its deficiency is: 1. current take the air line, and water outlet is concentrated, and does not disperse, and substrate concn is inhomogeneous; 2. surging force is larger, the biological microenvironment of destructible; Limited by hole count, be difficult to realize large-scale water distribution uniformity, and local resistance loss is large, energy consumption is high.
Ring-type water distributor major advantage is: 1. reactor bottom matrix is relatively even; 2. hydraulic resistance is relatively little.Its deficiency is: 1. longitudinally current are inhomogeneous; 2. laterally whipping force is larger, the biological microenvironment of destructible; 3. when design and installation, require high (as water inlet supervisor in all pressing turning spurt water device does not overlap with the central axis of closed cavity), need only in design and installation slightly deviation, be just difficult to guarantee the homogeneity of water distribution.
Spiral water distributor major advantage is: 1. the calculating of water distributing pore, design, production and installation are all more convenient; 2. water distribution is even, is difficult for stopping up.Its deficiency is: the cloth water surface is larger, therefore cloth water pressure is low, impulse force is the inducement that causes the short stream of reactor not.
Utility model content
The deficiency that the utility model exists for above-mentioned a few class water distributors, improves the water distributor of UASB reactor, and a kind of low cost is provided, and makes simply, and water distribution is even, and can anticlogging substrate slight drag water distributor.
A kind of UASB substrate slight drag even water distributor, comprise circular water distribution board, described water distribution board is arranged on the top of a turbination container, and the opening of turbination container bottom is water-in, has also laid three layers of pebbles layer being comprised of different-grain diameter pebbles respectively on described water distribution board.
Wherein said water distribution board posticum is evenly arranged on from the center of circle to circumference and by dredging to close a series of concentric(al) circless, the posticum quantity on each concentric(al) circles and the proportional relation of concentric(al) circles diameter, and the pitch-row on each concentric(al) circles and concentric(al) circles diameter are inverse relation.
Pebbles particle diameter and the floor height of wherein said three layers of pebbles layer are respectively: the particle diameter of bottom is 2.5
3.5cm, floor height 4
5cm; The particle diameter in middle layer is 1
2cm, floor height 1.5
2.5cm; The particle diameter on upper strata is 0.3
0.7cm, floor height 1.5
2.5cm.
The beneficial effects of the utility model:
(1) with low cost, make simple.
(2) flow resistance is little, and current disperse.
(3) water flow impact pressure is suitable, reduces the destruction to biological microenvironment.
(4) water distribution is even, is difficult for stopping up.
Accompanying drawing explanation
Fig. 1 is UASB substrate slight drag even water distributor structural representation.
Fig. 2 is the water distribution board schematic diagram in UASB substrate slight drag even water distributor.
In accompanying drawing: 1.UASB; 2. upper strata pebbles layer; 3. middle layer pebbles layer; 4. bottom pebbles layer;
5. water distribution board; 501. water distribution board posticums; 6. turbination container; 7. water-in.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The main body UASB of reactor is made by cylindric transparent organic glass, and bottom connects a turbination container, and cone angle is 90
0angle, current enter from turbination container lower openings.The about 6.28m of reactor body volume
3.Top at turbination container arranges water distribution board, water distribution board posticum is evenly arranged on from the center of circle to circumference and by dredging to close a series of concentric(al) circless, posticum quantity on each concentric(al) circles and the proportional relation of concentric(al) circles diameter, the pitch-row on each concentric(al) circles and concentric(al) circles diameter are inverse relation.Being posticum quantity on each concentric(al) circles, concentric(al) circles diameter is larger at the most along with concentric(al) circles diameter increases by few, and posticum quantity is more, and the pitch-row on each concentric(al) circles (chord length) is not wait, and concentric(al) circles diameter is larger, and the pitch-row in its upper water-out hole is also less.The aperture of all posticums is 8mm.
On water distribution board, lay three layers of pebbles layer being formed by different-grain diameter pebbles respectively: the particle diameter of bottom is 3cm, floor height 4.5cm; The particle diameter in middle layer is 1.5cm, floor height 2cm; The particle diameter on upper strata is 0.5cm, floor height 2cm.Upper strata aspect flushes with turbination container upper limb.
The particle diameter of bottom pebbles is about 3cm, and the distance between each crack of stone is relatively large, and for water distribution, its flow resistance is almost nil.The particle diameter of middle layer pebbles is about 1.5cm, and for water distribution, its flow resistance such as is essentially at the resistance.The particle diameter of upper strata pebbles is about 0.5cm, and for water distribution, current exist slight drag.By the accumulation of three layers of different-grain diameter pebbles, can realize water distribution uniformity and prevent from stopping up, and water flow impact pressure is suitable, can reduce the destruction to biological microenvironment.
