Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of mechanical cyclone-flocculation of the present invention is separated high efficiency clarification tank.
Embodiment
Describe the present invention below in conjunction with accompanying drawing, the description of part of the present invention is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
One machinery cyclone-flocculation is as shown in Figure 1 separated high efficiency clarification tank, comprises central tube 1, swirl-flow devices, straight guide shell 4, flocculation zone 11,
Flocculation zone 11 is positioned at outside central tube 1, is connected therebetween by straight guide shell 4,
Swirl-flow devices is arranged on top, and axis overlaps with central tube 1 axis,
Swirl-flow devices comprises blade rack 121 and some blades 122, and blade 122 is fixed on blade rack 121, blade rack 121 by driving arrangement, as electric motor, driven rotary, and then band rotor blade 122 rotate,
Central tube 1 Lower Half is the first reaction settling section I, and the first reaction settling section I is inverted conical cavity,
The position of straight guide shell 4 is corresponding with swirl-flow devices position.
Blade rack 121 comprise central shaft and distributed to free end by the inboardend of central shaft, length increases successively and some with blade connecting rod 121a with central axis, is designed to three in the embodiment of the present invention,
Each blade 122 is fixed on each blade connecting rod 121a, the blade connecting rod 121a that length is the shortest is fixed with two blades 122, blade 122 number on the blade connecting rod 121a that length is larger is greater than the number of the less blade connecting rod 121a blade 122 of length, and in the embodiment of the present invention, three blade connecting rods fix two, four and six blades 122 successively.This design of swirl-flow devices, makes it form vertical gradient, utilizes low speed to promote eddy flow and forms eddy flow energy gradient from bottom to top.High turbidity raw sewage directly enters in pond, eddy flow is formed under the pushing effect of swirl-flow devices, mutual Collision coagulation between water-borne glue body particle is made to carry out incorgruous flocculation formation flocculation preliminary sedimentation gradient from bottom to top, solving the flocculation of flocculation basin in traditional Water purification scheme and precipitation cannot the contradiction of organic unity, finally realizes high efficient solid and liquid separation.The swirl-flow devices set up and first reacts settling section I and designs and combine, be conducive to mud-water separation, greatly reduce the water ratio of spoil disposal water, save subsequent set mud sump volume, a difficult problem for spoil disposal difficulty when simultaneously also solving traditional settling tank coagulating kinetics ultra.Winter low temperature low turbidity raw water directly enters in central tube 1, and the existence of the suspension slime layer that the promotion due to swirl-flow devices in central tube 1 is formed, solves the unmanageable difficult problem of low temperature and low turbidity water.By the design to swirl-flow devices, swirl-flow devices can be made to change rotating speed to ensure flocculating effect with the change of water quality, the water yield, the water factory of any scale can be applied to.
Also comprise water inlet pipe 1, water inlet pipe 1 gos deep in central tube 1, and its nozzle 2 is positioned at below swirl-flow devices, the top of the first reaction settling section I.
Flocculation zone 11 has one or more, and when arranging multiple flocculation zone 11, each flocculation zone 11 is uniformly distributed around central tube 1.
Flocculation zone 11 Lower Half is the second reaction settling section II, second reaction settling section II is inverted conical cavity, sludge out pipe 10 has many, and the entrance end of sludge out pipe 10 is positioned at the bottom of the first reaction settling section I and second reaction settling section II, and exit end stretches out settling pond 100.The design of the second reaction settling section II, make spoil disposal smooth and easy, spoil disposal solid content is high.
In straight guide shell 4 bottom, be provided with the oblique flow deflector 5 tiltedly had a down dip in flocculation zone 11 around central tube 1 outer wall,
In flocculation zone 11, the position relative with oblique flow deflector 5 be provided with the fanning strip 6 tiltedly had a down dip in flocculation zone 11.
The angle that oblique flow deflector 5 and fanning strip 6 tilt is more than or equal to 55 degree and is less than or equal to 70 degree.
Be provided with sieve plate 7 in the below of top end opening place, flocculation zone 11, water leg 8, sieve plate 7 is distributed with some through holes tilting to extend, water leg 8 is connected with rising pipe.
The inner entirety of settling pond 100 is cubes.Adopt this design, teaming method is flexible, can share pool wall, reduce construction costs and difficulty of construction, be applicable to the large-scale water treatment scale that raw water quality variation range is large, save floor occupying area, decrease construction investment between the body of pond.
When the present invention uses, former water enters water inlet pipe 1 through water pump lifting, inorganic coagulant (as PB1 gene) or high-molecular coagulant adopting (as polyacrylamide PAM) is added at water inlet pipe 1 streamline central point, line mixer is relied on to complete the blending dispersion of medicament, former water flows after certain hour in the duct, add high-molecular coagulant adopting (as polyacrylamide PAM) or inorganic coagulant (as PB1 gene) in reducing place of the nozzle 2 of water inlet pipe 1, rely on submerged orifice outflow to complete instantaneous mixing; According to the difference of former water sediment concentration, during high sediment concentration, PAM adds at water inlet pipe 1 line mixer, and PAC adds in reducing place; During low sand-carrying capacity, PAC adds at water inlet pipe 1 line mixer, and PAM adds in reducing place; Former water enters central tube 1 by the eccentric reducing of water inlet pipe 1 nozzle 2, forms eddy flow state by swirl-flow devices, relies on swirl-flow devices pushing effect to form eddy flow and makes the mutual Collision coagulation of suspended particle, reach the effect of flocculation in central tube 1; The eddy flow stiffened region of water inlet pipe 1 nozzle more than 2 provides the higher turbulence intensity needed for the coagulation initial stage, higher upflow velocity completes the waterpower sorting of granular flocs unit simultaneously, namely Large stone, closely knit particle rely on gravity to overcome the jacking force of ascending current, be settled down to the first reaction settling section I of central tube 1 bottom, complete solid-liquid separation; The flocs unit of small particle size, is constantly grown up into the fine particle in water by catching at ascending current backwater effect low suspension in water.Former water enters after central tube 1 completes eddy flow, after straight guide shell 4 carries out fluid stable, routs up and enters flocculation zone 11, along with water-carrying section increase, flow velocity diminishes gradually, complete flco and grow up.The sieve plate 7 set up at top, flocculation zone 11 controls remaining flco in water further.Mud sinks in the first reaction settling section I and second reaction settling section II, because hydrostaticpressure is powerful, when opening mud valve, producing very high flow velocity, mud is discharged very smoothly.The conical design of the first reaction settling section I and second reaction settling section II, and the suction produced when swirl-flow devices promotes eddy flow and spoil disposal is all spoil disposal reason smoothly with promoting.
A kind of mechanical cyclone-flocculation of the present invention is separated high efficiency clarification tank, solving the flocculation of flocculation basin in traditional Water purification scheme and precipitation cannot the contradiction of organic unity, and solve and single pool size become large after, first step flocculation preliminary sedimentation section is depended merely on hydrocyclone and has been carried out the problem that flocculation preliminary sedimentation cannot realize.
