Description
Technical field
The present invention relates to a kind of three-dimensional spiral-flow type water distributor and applications.
Background technique
During Industrial Waste Water Treatments, high concentrated organic wastewater is handled frequently with PEIC anaerobic reactor technology, wherein
Water-distributing device in anaerobic reactor is the core component of reactor, the water distribution manner being widely used at present include point type water distribution and
Dendritic water distribution two ways, both modes realize the water distribution in anaerobic reaction to a certain extent, but there are also disadvantages.
For point type water distribution during anaerobic reactor handles high concentrated organic wastewater, there are cloth water spots easily to block, after blocking
Hardly possible cleaning；Cloth water spot uses gravity stream, and exit velocity is low, and mixing effect is poor；Point type water distribution installation number is big, and installation process is numerous
It is trivial；Water body flow direction is pulling flow type from bottom to top, easily there are problems that dead zone.
And dendritic water distribution is during anaerobic reactor handles high concentrated organic wastewater, and there are water distribution is uneven, reactor
There are dead zones for bottom；Dendritic water distribution easily blocks, while hardly possible is found, hardly possible is cleared up after blocking；Interior recycled biogas band water cannot achieve together
The problem of walking water distribution.
To sum up, existing water distribution manner cannot fully meet the water distribution requirement of anaerobic reactor.
Summary of the invention
To solve the above-mentioned problems, proposing a kind of three-dimensional spiral-flow type water distributor and application, the present invention can solve the present invention
The problem of certainly traditional water distributor easily blocks, water distribution is uneven and biogas band water cannot synchronize water distribution.
To achieve the goals above, the present invention adopts the following technical scheme that：
A kind of solid spiral-flow type water distributor, including water distributor ontology, the water distributor ontology have double-layer channel, every laminar flow
It is both provided with multiple deflectors being obliquely installed in road, makes every laminar flow road in counter-clockwise helical type, the edge pair of each deflector
It should be provided with jet port, water outlet is projected along the corresponding tangential direction of water distributor, form counter-clockwise helical fluid；
First layer runner connects recycled biogas band water in anaerobic reactor, forms rotation water distributing of the biogas with water, the second layer
Runner connects anaerobic reactor water inlet, forms anaerobism water inlet rotation water distributing, and biogas band water and anaerobism are intake and sprayed in same section,
Increase injection flow and anaerobism is diluted.
This design method can either make each layer of horizontal fluid projected reflect to form turbulent flow by tank body, in eddy flow
Under the collective effect of turbulent flow, anaerobic reactor bottom is made to form the upward unitary rotation of spiral, guarantees that water distribution is uniform, without dead
Area, bottom mixing effect are good.Meanwhile two layers independent runner can independent independent water distribution, be respectively completed the independence of anaerobism raw water
Water distribution and biogas are able to solve the problem of water distributor biogas band water can not synchronize water distribution with the independent water distribution recycled in water.
Further, the double-layer channel is respectively arranged at the both ends of water distributor cloth water cap, mutually isolated each other.
Further, the position of the deflector of the different layers runner is corresponding.
Further, each laminar flow road is provided with multiple diversion trenches, is provided with deflector at the outer of each diversion trench, makes
Corresponding deflector is parallel with the tangential direction at the tie point at the fan-shaped edge of the diversion trench.
Preferably, the number of the deflector in each laminar flow road is 16, even circumferential distribution, and jet port is average using 22.5 °
Distribution.
Further, the diversion trench interval in same layer runner blocks, and is provided with jet port at the diversion trench notch not blocked.
Further, the block-up position of the diversion trench between different layers runner is interlaced.That is leading positioned at same position
Chute is blocked in first layer runner, and second layer runner is provided with jet port.
Further, the water distributor is additionally provided with water inlet pipe, and the water inlet pipe is divided into more parts, every part by hydroseparator structure
Different runners is delivered to by the straight tube of different length.
Further, it is provided with return pipe in the cloth water cap, is provided with and is flexible coupling on return pipe, return pipe one end and cloth
Water cap connection, the other end are connect with steam-water separator.
Further, gas vent is provided at the top of the cloth water cap.
PEIC anaerobic reactor, including above-mentioned three-dimensional spiral-flow type water distributor.
Compared with prior art, beneficial effects of the present invention are：
Three-dimensional spiral-flow type water distributor uses Dual-layer runner design, while upper lower flow channel independence water distribution, upper layer cloth water flow
Road connects recycled biogas band water in anaerobic reactor, and biogas band water is projected from upper layer runner level, forms rotation of the biogas with water
Water distribution, lower layer's runner connects anaerobic reactor water inlet, and by bottom helical flow path, anaerobism water inlet is penetrated in lower layer's runner flat spin
Out, anaerobism water inlet rotation water distributing is formed, while biogas band water and anaerobism are intake and sprayed in same section, increase injection flow is simultaneously right
Anaerobism is diluted, and solves the problems, such as that water distributor biogas band water can not synchronize water distribution.
Three-dimensional cyclone water distributor is installed using modularization, and scene directly lifting welding, easy for installation, speed is fast, solves to pass
System point type water distribution problem erroneous for installation.
Three-dimensional spiral-flow type water distributor conical top cover is combined with horizontal-jet mouth, and strain and sewage in tank is made to form rapids up and down
Stream, while with level rotary flow to combination, solving conventional port water distribution and dendritic water distribution or more pulling flow type water distribution, there are dead zone, moisturizings
The problem of effect difference.
It is equipped with gas vent above three-dimensional spiral-flow type water distributor cone cap, is avoided because gas collection ties up water distributor space in water distributor,
Water distribution effect is influenced, solves the problems, such as that traditional water distributor gas collection causes water distribution non-uniform.
Solve traditional water distributor easily blocks, water distribution is uneven, cleaning difficulty, complex installation process, biogas cannot with water
The problem of synchronous water distribution.
After water distributor water distribution is uniform, volumetric loading improves 30%, and capacity of resisting impact load improves 50%, easy to operate, exempt from
Maintenance.
