Abstract

In a process for granulating a melt, the melt is quenched by means of water, a mixture of granules and water being produced. In a dewatering apparatus, this mixture is dewatered, a solids-loaded wastewater being recovered and fed to a collection tank. In the collection tank, an inclined plate settler is disposed and is constantly immersed herein in the water. The solids-loaded wastewater is fed to the collection tank in such a manner that at least a portion of this solids-loaded wastewater flows through the inclined plate settler in the collection tank from bottom to top and at the top outlet of the inclined plate settler a substantially solids-free water stream flows off from the collection tank.

Description

Be used for melts process for granulating and device
Technical field
The present invention relates in general to and is used for melts, especially slag (slag melt, slagmelt) process for granulating and device.
Background technology
In the blast furnace slag granulating equipment, from the effusive slag of blast-furnace slag passage by means of shower nozzle and nozzle system and utilize water to carry out granulation.In this case, formed so-called slag sand, a kind of mainly is with vitreous state solidified fine particle product.In order to form the slag sand that is applicable to manufacture of cement, in the slag sand main field of application, the heat of slag must be removed by the method for similar quenching (shock-like cooling).For this reason, according to the content of slag, need the process water of relatively large amount.In order to make the water in slag sand dehydration and the recovery technology loop, will supply with dehydration equipment (dewatering plant) by water and particulate mixture that course of injection produces.The waste water of removing from such dehydration equipment still has a certain amount of solid.This solids content can deposit or cause the apparatus assembly abrasion in further waste water uses in apparatus assembly.For this reason, after settle solids, the known subsider (settling tank) that for example utilizes in the downstream of dehydration equipment reclaims purer process water relatively from it.Yet such subsider needs sizable structural volume (structural volume), and needs the relatively complicated deposition solid of frequently removing.
Replacedly, DE10216415 has proposed to utilize hydrocyclone to purify waste water from dehydration equipment at least in part.Although this technology allows solid is separated from water, especially quickened the to have dewatering bunker static dehydration of (dewatering silo), but it needs the operation of complicated hydrocyclone on the engineering science, and need be used to operate the additional energy consumption of hydrocyclone fresh feed pump.In addition, because the slag sand deposition, it is blocked especially easily that such hydrocyclone seems.
Further problem is owing to be present in the latent hydraulicity of the tiny granulated slag sand in the waste water to be clean.Wet slag sand is in the character that forms similar deposit concrete except that in fact having sclerosis after anhydrating.Therefore, in the process of purification, must thoroughly avoid the sedimental sclerosis of slag sand from the waste water of dehydration equipment.
Summary of the invention
The object of the present invention is to provide a kind of slag, especially slag process for granulating of being used for, by simple means, the present invention might reclaim not to be had the solid current basically and has lower because the susceptibility (susceptibility) that sclerosis slag sand deposition results in blockage.By according to being used for the melts process for granulating described in the claim 1, can realize this purpose according to the present invention.Similarly, provide the device that is used to implement this method.
In the method for the invention, by means of water, melts is quenched in a kind of known mode, forms the mixture of particle and water.In dewatering unit, this mixture is dehydrated, reclaims the waste water that has solid (solids-loaded), and supplies with receiving tank (collectionbank).According to the present invention, inclined plate settler is set in receiving tank and it here is immersed in the water always.To have that solid waste water is supplied to receiving tank by this way and cross inclined plate settler the receiving tank from the bottom to overhead stream so that at least a portion this has solid waste water, and, there are not the solid current to flow out basically from receiving tank at the top exit place of inclined plate settler.By very simple mode, this method might reclaim do not have basically the solid current and in this case since sclerosis slag sand settling result in blockage almost do not have a susceptibility.In fact, found inclined plate settler (inclined platesettler) (it also is known as dull and stereotyped settling vessel (lamellae plate settler) of shell or tilted plate separator), if it never parches, then it has lower susceptibility for the obstruction that causes owing to sclerosis slag sand settling.In the method for the invention, this is guaranteed by inclined plate settler being arranged in the receiving tank and with its fact that here is immersed in the water always.Even process disruption and granulating equipment relatively than the situation during the long idle under, inclined plate settler keeps being immersed in the water, makes slag sand not harden.In addition, owing to the layout of inclined plate settler in receiving tank, so do not need to be used for the exceptional space of secondary-cleaned equipment.Further advantage is that inclined plate settler is simple and operation is reliable, does not have movable part (moving element) and do not need special repair and in fact do not need to safeguard to spend.In addition, in receiving tank, be easy to as required and change at an easy rate.The further advantage of the inventive method is that the secondary-cleaned in inclined plate settler is a pure static process, does not need extra energy for this process.
Receiving tank advantageously has doline outlet (funnel-shaped outlet), and sediment (sediment sludge) takes out from this doline outlet, and once more for being back in the dewatering unit.This produces the constant solids concn in corresponding circuit, and in fact the efficient of this process be further enhanced.
Inclined plate settler advantageously is suspended in the receiving tank on support frame and can slides on this support frame.Therefore, installation and the removal of inclined plate settler in receiving tank is simple especially.
In a preferred embodiment, inclined plate settler is made up of a plurality of modules, and these modules individually are suspended on support frame (support frame) in the receiving tank and by sliding on support frame and arrive the working position.Therefore, even under the situation of limited structural volume, the installation of inclined plate settler and removal are also simpler.
Dewatering unit advantageously comprises rotatable dewatering drum, and (the dehydration cylinder, dewateringdrum), it is arranged in the scraper bowl.Method of the present invention can be moved continuously by such dewatering drum.Dewatering drum advantageously is set directly at the top of receiving tank first area, and inclined plate settler is set in the adjacent second area (it laterally separates with the first area) of receiving tank.By this design, dewatering drum and receiving tank and inclined plate settler are combined and form compact especially unit.
Yet dewatering unit also can similarly comprise one or more dewatering bunkers (dewateringsilo) or another one dehydration spiral (dewatering screw), and its waste water is supplied in the receiving tank.
The device that is used to implement the inventive method comprises in a known way: jet apparatus, be used for current are injected melts, and form the mixture of particle and water; Dewatering unit is used to make this mixture dehydration, reclaims to have solid waste water; And receiving tank, its supply is had solid waste water.According to the present invention, in receiving tank, be arranged in such a way inclined plate settler, cross inclined plate settler the receiving tank with the solid waste water that has that is immersed in it in water and will supply with at least a portion of receiving tank always from the bottom to overhead stream, and sentence at the top exit of this inclined plate settler and not have the solid current to flow out basically from receiving tank.

Embodiment
Be usually the granulating equipment of design in Fig. 1, represent with label 10.Granulating equipment 10 has the known prilling tower 11 of type itself.In prilling tower 11,, water is injected the slag 14 of discharging from slag releasing channel (tapping channel) 12 for granulated blast-furnace slag.This shock-type quenching makes slag melt 14 granulations and forms slag sand.Based on the shower nozzle 16 that a plurality of water stream 18 is injected melt-flow 14, finish this granulation in a known way.The mixture of gained water and slag granules is collected in the granulation tank 20 that is arranged on prilling tower 11 lower regions.Then, mixture enters the dewatering unit 24 through divider passage (distributorchannel) 22 from granulation tank 20.Dewatering unit 24 is preferably the INBA  dewatering drum available from Paul WurthS.A, as for example described in US4204855 or the US4289519.
As shown in Figure 1, the slag sand 28 available from dewatering unit 24 is delivered to suitable storage location 29 by travelling belt 26.On the contrary, the isolating solid water that has falls into receiving tank 30 (it is provided with and is also referred to as hot water tank for this purpose) as waste water from dewatering drum 24 in dewatering unit 24.Although dewatering unit 24 is by forming the filteration of slag sand layer (not illustrating in greater detail) in zone, dewatering drum middle and lower part, but because processing condition, so the inevitable this waste water that is removed still has solid fine particle, the especially slag sand residues of relative higher proportion.
Receiving tank 30 is configured to funnel shaped in lower region thereof, and preferably has outlet connection (outlet connection) 32 there.Via outlet connection 32, the sediment that is collected in receiving tank 30 lower regions is removed.This sediment preferably is transported in the divider passage 22 (upstream of dewatering unit 24) by erosion resistant pipeline 34 by pump.In this way, sediment is provided for above-mentioned filteration once more.According to the recirculation loop of label 36, set up the balance of fine particle concentration like this.
According to Fig. 1, can find out further that inclined plate settler 40 is set directly in the receiving tank 30.Such inclined plate settler or lamellae separator 40 are the tripping devices that are used for separating the single phase in the dispersion system of different densities.Inclined plate settler is made up of a branch of parallel oblique shell (thin slice) or pipe (waste water to be clean upwards flows by it) basically.Because action of gravity, solid particles sediment and landing are to shell or manage the bottom and disengaging inclined plate settler 40.
Inclined plate settler 40 is installed in the upper area of receiving tank 30, is preferably mounted on the straight outer wall.Inclined plate settler 40 has such effect, that is, make the solid water of collecting in the receiving tank 30 that has not have solid matter to be used to be recycled to the water treatment loop basically.Purification has especially reduced wearing and tearing, slag sand deposition and sclerosis in all devices assembly (supplying with its purifying waste water from inclined plate settler 40) from the solid waste water that has of dehydration equipment 24.In this case, the layout of the inclined plate settler 40 in the receiving tank 30 that diagram is described can make have solid waste water above it the environment division of process (plantsection) be reduced to minimumly, be reduced to the part between dewatering unit 24 and the receiving tank 30 in the ideal case.In addition, thus the length of recirculation loop 36 is also reduced to minimum.Using inclined plate settler 40 also to allow to carry out effective process water with minimum monitoring, maintenance and processing costs handles.In addition, inclined plate settler 40 can be incorporated in the existing receiving tank 30 and not need extra structural volume.Inclined plate settler 40 preferably is used for purifying the whole waste water streams that keep from dewatering unit 24 after removing sediment.Replacedly, for example, adopt less relatively volumetrical receiving tank 30, the less design of inclined plate settler can be used for the purification process of part liquid stream.
Inclined plate settler 40 has open top 42, removes from receiving tank 30 by the solid current that do not have basically that this opening is cleaned.Compare with remaining water level in the receiving tank 30, open top 42 is in lower position and laterally seals by corresponding partition wall 44.This has guaranteed to have in the solid water inflow inclined plate settler 40, and only has purified water at open top 42 places, and it can not turn back in the receiving tank 30 therefrom.Under the situation of the suitable loading capacity of receiving tank 30, because highly different, in this case according to the spontaneous generation of inflow of arrow 46 indications.The solid waste water that has that has so just produced the spontaneous inclined plate settler 40 of flowing through from bottom to top flows, and removes solid gradually by sedimentation there.So just do not need to be used to move the further measure of tilt flat plate collector 40.Solid that from inclined plate settler 40, settles and fine particle only by action of gravity according to fall back lower region in the receiving tank 30 of arrow 48.As mentioned above, the solid in the sediment is recirculated to dewatering unit 24 according to arrow 36 directions, and is filtered to small part there.Therefore, do not need to remove separately and handle the solid of separating.Should be noted that the removal speed of process outlet connection 32 and pipeline 34 always is lower than from the feeding rate of dewatering unit 24.Advantageously, this removal speed so that tilt flat plate depositor 40 chosen in the mode that the best loads always.
In order to cool off the water that is melted thing used heat (waste heat) heating, this water for example is delivered to cooling tower and catch basin 52,52 ' by pump from the hold tank 50 that is connected to top exit 42.Therefore, the water section by inclined plate settler 40 purifying directly is suitable for further being particularly useful for shower nozzle 16 as process water.Still be pointed out that, simply keep the constant loading capacity of receiving tank 30 guaranteed that in simple mode inclined plate settler 40 keeps being immersed in the water always.This especially guarantees can not parch owing to slag sand is sedimental in inclined plate settler 40 and hardens.In addition, described combined loop according to arrow 36 and arrow 54 has been guaranteed not under the situation of needs further step, the automated cycle of groove content under the constant water level situation of receiving tank 30.
