Abstract

The utility model discloses a reciprocating type baffle plate flocculating tank with a good coagulation effect, which belongs to coagulation devices for water treatment and is improvement to the reciprocating type baffle plate flocculating tank. The reciprocating type baffle plate flocculating tank comprises a medicine chest containing coagulant liquor as well as a static mixer and a flocculating tank connected with the medicine chest through a pipeline, wherein the flocculating tank is divided into a sewage inlet area, a mixing area, a flocculating area and a settling area sequentially communicated by a baffle plate; and a sewage water inlet is formed in the upper part of the sewage inlet area; the mixing area is divided into a plurality of communicated cells by n-shaped baffle plates which are arranged in negative direction, wherein the corners of the baffle plates are arc-shaped; the width of the flocculating tank is greater than the pitch among the baffle plates; and the water inlet area is a three-cell threaded turbulent flocculating tank. The reciprocating type baffle plate flocculating tank has the beneficial effects that the coagulating dead area of the baffle plate flocculating tank is eliminated and the energy consumption is reduced, the reaction time in the mixing area is short and the reaction is severe, and the water flow in the flocculating area is stable and the flocculating body formed is large in density, so that the flocculating effect is improved.

Description

The reciprocating type dividing plate flocculation basin that coagulation effect is good
Technical field
The utility model relates to the good reciprocating type dividing plate flocculation basin of a kind of coagulation effect, belongs to the water treatment coagulation apparatus, is the improvement to reciprocating type dividing plate flocculation basin.
Technical background
Handle in coagulation, precipitation, all technology of filtration at water supply purification and waste water physicochemical, coagulation is indispensable preposition key technique, is the basis of precipitation, filtration treatment.The conversion unit of coagulation process is flocculation basin.Therefore, flocculation basin reasonably improves, and not only can improve effluent quality, can also reach purpose energy-conservation and the reduction working cost.
Present large and medium-sized water factory is extensive use of reciprocating type dividing plate flocculation basin, it have fairly simple, the flooding velocity of structure greatly, characteristics such as stronger water-fast stroke load and construction management be convenient, yet, when current flow through the rectangular edges wall of reciprocating type dividing plate flocculation basin, formed a coagulation dead band in a big way at the gallery head, make the velocity slope of current too high, clash into excessive, easily make and assemble good flco fragmentation, and the undesirable of flow condition makes most of energy become effective consumption, prolong mixing time, increased the flocculation basin volume.
Summary of the invention
There is the slough in order to overcome existing reciprocating type dividing plate flocculation basin, causes the undesirable of flow condition, influence the compaction rate of floc particle, make current milder, ensure coagulation effect; The utility model provides a kind of reciprocating type dividing plate flocculation basin of coagulation effect.
The utility model is realized with following technical scheme, the reciprocating type dividing plate flocculation basin that a kind of coagulation effect is good, the medicine-chest that coagulant solution is arranged in it comprises, by static mixer and the flocculation basin that pipeline is connected with medicine-chest, described flocculation basin is divided into sewage inhalant region, mixing zone, flocculation zone and the settling region of UNICOM successively with dividing plate; Top at inhalant region is provided with sewage inlet; Described mixing zone is separated into a plurality of lattice that are connected with the ∩ shape dividing plate that arranges each other in the other direction; The width of described flocculation zone is greater than the spacing between dividing plate; Described inhalant region is three lattice perforation eddy flow flocculation basin.
The width of preferred described flocculation zone is 1.5-2 times of clapboard spacing.
Described settling region is to be made of 3 parallel settling tanks, each settling tank all with flocculation zone UNICOM, and respectively be provided with water port.
Its principle is: the coagulating agent aqueous solution is at first by static mixer and water inlet short mix, current flow into through 3 lattice perforation swirling flow flocculation basin, make that the initial stage of hybrid reaction is strong, it is too small because of velocity slope to have remedied reciprocating type dividing plate flocculation basin flat segments, and does not reach the deficiency of the particle collision of top efficiency.And whole rectangular edges walls of mixing zone are arranged to circular arc, also be in order to improve the velocity slope of particle collision to greatest extent, coagulating agent fully to be mixed with water.And circular arc limit wall makes current produce bigger wake zone, has reduced friction resistance.Simultaneously, the motion of low flow velocity is convenient to conserve energy reduction head loss, is shortened the reaction times.Flocculation zone limit wall is smooth, and flow process is longer, can reduce the flow velocity of current, prolonged flocculation the time, formed flco is more closely knit, be beneficial to the sedimentation of flco.At last, current carry flco and enter the settling region, and flco has been finished the whole process of coagulation process because action of gravity sinks at the bottom of the pond.
The beneficial effects of the utility model are, eliminated the coagulation dead band of dividing plate flocculation basin, reduced the consumption of energy, and the reaction times of mixing zone is short and violent, the current of flocculation zone flco steady and that form is closely knit big, improve coagulation effect, thereby realized the improvement to reciprocating type dividing plate flocculation basin.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified
Fig. 1 is structural representation of the present utility model.
Among the figure: 1. medicine-chest, 2. static mixer, 3. inhalant region, 4. mixing zone, 5. flocculation zone, 6. settling region, 7, the sewage mouth.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, it has the medicine-chest 1 of coagulant solution in comprising the good reciprocating type dividing plate flocculation basin of a kind of coagulation effect, by static mixer 2 and the flocculation basin that pipeline is connected with medicine-chest 1, flocculation basin is divided into sewage inhalant region 3, mixing zone 4, flocculation zone 5 and the settling region 6 of UNICOM successively with dividing plate; Be provided with sewage inlet 7 on the top of inhalant region 3; The ∩ shape dividing plate that described mixing zone 4 usefulness arrange each other in the other direction is separated into a plurality of lattice that are connected; The width of described flocculation zone is 2 times of spacing between dividing plate; Described inhalant region 3 is three lattice perforation eddy flow flocculation basin.Described settling region 6 is to be made of 3 parallel settling tanks, each settling tank all with flocculation zone 5 UNICOMs, and respectively be provided with water port.
Coagulant solution is by the effect and water inlet short mix of static mixer in medicine-chest, 3 lattice of flowing through then perforation eddy flow flocculation basin, mix and mix initial reaction with sewage strong, further mix with sewage the mixing zone of flowing through, make water can form closely knit floc particle at flocculation zone, last water carries flco makes settling of floccus at the bottom of the pond in the settling region, and supernatant liquor flows out from the top of settling region, has finished whole coagulation process.
