In said flocculation plant, first of flocculation plant, flocculation plant stirs jar and second and stirs jar by pipe connection.Magnetic micro floc with hundreds of μ m sizes jar at full speed stirs former water and produces through stirring with first, and the magnetic micro floc is sent to second with former water through said pipeline and stirs jar.So, stirring former water through stirring jar with lower velocity with second, the magnetic micro floc forms the magnetic floss with a few mm sizes.
Summary of the invention
Yet, the flocculation plant of japanese laid-open patent application No.2005-218887, the structure that has is that the first stirring jar and second stirs the setting respectively of jar quilt, and passes through pipe connection.Therefore, said device has the big problem of size.
Equally; In the flocculation plant of japanese laid-open patent application No.2005-218887; Flow to first stir jar with second stir jar former glassware for drinking water free surface is arranged, so, such as shaking in the environment in the ship; Stir jar and mobile (laminar flow) in the second stirring jar, the influence that shaken by free surface first.Thereby existence can not produce the problem of magnetic micro floc and magnetic floss well.
In addition; In the flocculation plant of japanese laid-open patent application No.2005-218887; Former water at full speed directly stirs jar from first through said pipeline and flows to the second stirring jar; Thereby the generation interference is flowed in the former water that second stirs in the jar, so, exist the magnetic floss of generation to flow and ruined possibility by interference.
Consider this environment and accomplished the present invention.The purpose of this invention is to provide a kind of flocculation plant, said flocculation plant can suitably produce magnetic micro floc and magnetic floss when reducing said device size.
To achieve these goals; A kind of flocculation plant is set according to a first aspect of the invention to be comprised: stir jar at a high speed, said high speed is stirred jar and is used the stirring blade stirring with the rotation of first velocity of rotation to be added into the former water of magnetic particle and flocculation agent and in said former water, to produce the magnetic micro floc; Decelerating vessel, said decelerating vessel will flow out the speed of stirring the former water of jar at a high speed and be reduced to predetermined speed, and in said decelerating vessel, polymer coagulant is added into former water; Stir jar with low speed; Said low speed stirs jar use and flows out the former water of decelerating vessel and in former water, produce the magnetic floss with the stirring blade stirring of second velocity of rotation rotation; Said second velocity of rotation is slower than first velocity of rotation; Wherein stir at a high speed jar, decelerating vessel and low speed stir jar as a whole structure incorporate in the shell and sealed, and former water flows through the high speed that is full of by former water stir jar, decelerating vessel and low speed stirs jar.
According to a first aspect of the invention, because incorporating same shell into, high speed stirring jar, decelerating vessel and low speed stirring jar become one-piece construction, the possibility of the said plant bulk of existence reduction.The high speed of flocculation plant is stirred jar, decelerating vessel and low speed stir jar has the structure of sealing, and the internal flow that former water stirs jar in the high speed that deflates (air is discharged from jar) and be full of former water, decelerating vessel and low speed stir jar.Therefore, stirring jar, decelerating vessel and low speed stirring jar place at a high speed, former water does not have liquid-gas interface (free surface).Thereby, even when the sewage purification system be installed in such as ship rock in the state time, former water can flow in the inner flat of stirring at a high speed jar, decelerating vessel and low speed stir jar quietly, and does not have each jar place of ripple at flocculation plant.By this way, suitably produce magnetic micro floc and magnetic floss F.
Second aspect of the present invention is the flocculation plant according to first aspect; Wherein low speed stirring jar is multistage stirring container; Wherein a plurality of containers are connected continuously; Stir blade and be arranged on each and stir container place, and each velocity of rotation of stirring blade is set up along with the downward migration and reducing from the upper reaches of former water, thereby prevent that the magnetic floss that produces from breaking because of the velocity of flow of former water.
According to a second aspect of the invention, the velocity of rotation that is arranged on the stirring blade in each container that low speed stirs jar is set up along with the downward migration and reducing from the upper reaches of former water, is destroyed because of the velocity of flow of former water with the magnetic floss that prevents to produce.By this way, produce the magnetic floss well.
The third aspect of the invention is the flocculation plant according to second aspect; Each container of wherein multistage stirring container separates with thin plate with adjacent container; And the size that being used on thin plate flowed out the opening of former water is set to predetermined size; Thereby the SFM of the stirring blade in the stirring container of upstream end becomes and equals stirring container at the upper reaches and flow out to the speed at the former water of the stirring container in downstream.
According to a third aspect of the invention we; The multistage container that low speed stirs jar separates with thin plate and adjacent container; And the size that is formed on the opening that is used to flow out former water on the thin plate is set to predetermined size; Said thin plate is used for separately at the container at the upper reaches and container in downstream, thereby the SFM that blade is stirred in rotation in the stirring container at the upper reaches becomes and equals stirring container at the upper reaches and flow out to the speed at the former water of the stirring container in downstream.This can produce the magnetic floss well.
Preferably, stir at a high speed and jar seal, and comprise that air releasing tube road and water discharge pipeline, thereby, the said jar of situation use that former water and former water do not have free surface be full of at said jar.If former water has free surface, such as shaking in the environment in the ship, former water mobile in first stirs jar receives the influence that free surface shakes.On the other hand, according to aspects of the present invention, stir jar use is full of former water at jar sealed state at a high speed.Thereby, even under the situation of shaking, former water is in the influence of flowing and not shaken of stirring at a high speed in the jar.It is to stir jar continuously that the high speed of said aspect is stirred jar, and former water is continuously supplied wherein.Former water obtains the pump of pressure gradient, stirs jar and in the internal structure of the inner agitator of jar at a high speed in the inner mobile dependence of jar, and, stir and jar use owing to be full of the high speed of former water, and do not shaken or the influence of gradient at sealed state.Therefore, do not change from the coordinate system Central Plains current that stir at a high speed jar or agitator is seen.
In high speed stirring jar, equally preferably, locate to be provided with the axis of normal direction at the path (import and outlet) of high speed stirring jar, thereby the mean flow direction of high speed stirring jar is parallel to the axis of agitator perpendicular to the agitator of high speed stirring jar.Normal direction through path is set is vertical each other with the axis of agitator, and the mean flow direction of stirring jar at a high speed equals axial flow direction.Therefore, the mobile shortening through big rotation type circulation causes rotates hardly and realizes by stirring blade.In addition, produce along what rotate and flow around the agitator axle, thereby, might realize that actual is around in the ideal value of the hydrology in time of lag.
And preferably, in the time of when the surface of stirring blade moves to the import of stirring at a high speed jar about the normal direction of the import of the said line that stirs at a high speed jar near, it is opposite with the liquid-flow normal that the preceding normal that stirs blade is set.When the surface of stirring blade became near said import about the normal direction of import, the stream of discharging from the front surface that stirs blade was facing to the stream of the normal direction of import, thereby, might prevent to flow to the stream that stirs at a high speed jar and be shortened.
In addition, stir jar at a high speed and preferably have structure such as sealing cubes jar.Owing to stir at a high speed a jar up-right tank that is sealing, there is no need to be provided with and improve the turbulent dividing plate for the stirring of the inside of jar and hybrid reaction.
Equally preferably, low speed stirs and jar to be sealed, and comprises that air releasing tube road and water discharge pipeline, thereby said jar is used in the situation that former water and former water do not have free surface that jar is full of.Since because jar is full of by former water, former water stirs in the jar at low speed does not have liquid-gas interface (free surface), then stir the mobile influence of not shaken of jar Central Plains water at low speed.Particularly, in the environment such as ship, if former glassware for drinking water has free surface, the influence of shaking of free surface is stirred flowing of jar Central Plains water at low speed.Yet, when low speed stirs jar and is used in jar the state that is full of by former water, the influence of flowing and not shaken of stirring jar Central Plains water at low speed.On the contrary, when in stirring jar, air gap and free surface being arranged, the water (comprising air) of the inside of jar moves owing to the stirring jar shakes.It is the continuous stirring jar that has continuously flowing into and flow out water that low speed of the present invention stirs jar.Low speed stirs jar state in sealing and uses, and is full of by water, thereby pressure gradient, the low speed that the mobile dependence pump of water in inside drives stirs jar and the internal structure of inner agitator, and with shake or tilt irrelevant.Thereby from the low speed stirring jar system of coordinates that perhaps agitator is seen, handling stream does not have to change.
In addition, jar stir a jar mid-way decelerating vessel is set stirring at a high speed with low speed, the part that said decelerating vessel is stirred jar as low speed and have the roundabout structure, and flow to the speed stage ground reduction of the water of magnetic floss generation device.Though stirring jar and low speed stirring jar at a high speed is stirring jar separately, a stirring jar and a low speed stirring jar series connection are set to stir continuously retort at a high speed, and pass through the flow channel pipeline in succession.Decelerating vessel is arranged on stirs the mid-way that jar and low speed stir jar at a high speed, and flow passage also is set to roundabout, thereby decelerating vessel has avoided size to become big, and the reduction of the velocity of flow of former water.Thereby, might prevent to flow to the shortening that low speed stirs the said stream of jar.
In addition, in low speed stirs jar, equally preferably, and the axis of the agitator that the normal direction at the path place that low speed stirs jar is set to stir jar perpendicular to low speed, thus the mean flow direction that low speed stirs jar is parallel to the axis of agitator.The normal through being arranged on the path place and the axis of agitator are vertical each other, and the mean flow direction that low speed stirs jar becomes and equals the axis flow direction.Thereby, realize that by the rotation of stirring blade the shortening of the stream that big rotary type circulation produces takes place hardly.In addition, produce along around the flowing of agitator axis rotation, therefore, might realize that true delays is around in the ideal value of the hydrology in time of lag.
And, when the import normal direction of the line that stirs jar of low speed moves near the import that low speed stirs jar relatively on the surface of stirring blade, also be that the preceding normal that stirs blade preferably is set is opposite with the liquid-flow normal in low speed stirs jar.When the surface of stirring blade became more near said import about the normal direction of said import, therefore the stream of discharging from the front surface that stirs blade and the flowing opposite of the normal direction of said import might prevent to flow to mobile being shortened that low speed stirs jar.
In addition, low speed stirring jar preferably has the structure such as the up-right tank of sealing.Owing to stir at a high speed a jar up-right tank that is sealing, there is no need to be provided with and improve the turbulent dividing plate for the stirring of the inside of jar and hybrid reaction.And making low speed stir jar, to have a successive multilevel hierarchy then easier.The speed of rotation of in low stirring jar, stirring can be set to along with being from upstream to the downstream stages flows littler, thereby prevents that the magnetic floss that produces is destroyed, and promotes the growth of magnetic floc sizes.
According to any one aspect of the present invention, integrally to be incorporated in the shell owing to stirring jar, decelerating vessel and low speed stirring jar at a high speed, the size that reduces flocculation plant is possible.The high speed of flocculation plant is stirred jar, decelerating vessel and low speed stirring jar and is had sealed structure, and is full of under the situation of former water at these jars, and former current advance to stir at a high speed jar, decelerating vessel and low speed stirring jar.Thereby former water stirs jar, decelerating vessel and low speed stirring jar in high speed and locates not have free surface.Thereby, even when the sewage purification system use such as ship rock in the state time, former water can flow in the inner flat of stirring at a high speed jar, decelerating vessel and low speed stir jar quietly, and does not all have ripple at each jar place of said flocculation plant.By this way, magnetic micro floc and magnetic floss F produce well.
