Definitions
- the invention relates to a hydromechanical mixing apparatus for producing a mixture of powder or granular state material and fluid.
- Such an application is for example the producing of so-called thick slurry consisting of a solid phase combustion residue from a coal or oil fired power station and water at the ratio of 1/2 - 2/1 solid/fluid.
- thick slurry consisting of a solid phase combustion residue from a coal or oil fired power station and water at the ratio of 1/2 - 2/1 solid/fluid.
- the combustion residue of high specific surface would not or only slightly exhibit a cementing characteristic on its own, but in the presence of moisture and at a normal temperature, the materials of silicon or silicon and aluminium content combustion residue enter into a chemical reaction with calcium-hydroxide (Ca(OH)2) resulting from the mixing process and due to this chemical reaction, they are converted to a solid structure material. Intensive mixing ensures a rapid reaction rate. In this way, the thick slurry becomes solid after being delivered along in a pipeline and after being disposed. As a result of appropriate agitation, after solidification, a high volumetric density, high compression strength and low water permeability deposit is created.
- Ca(OH)2 calcium-hydroxide
- hydromechanical mixing procedures and mixing apparatuses To mix a powder or granular state material of 0.001 to 0.1 mm grain size and a fluid, there are so-called hydromechanical mixing procedures and mixing apparatuses. In the mixing space of the hydromechanical mixing apparatus, there are no facilities that would perform the agitation. This mixing procedure is based on the fact that the kinetic energy of a fluid flowing at a determined rate is sufficient by itself to mix the two components, when the bulk powder containing the solid grains must dynamically collide or baffle with the turbulently flowing fluid, having a high kinetic energy. By means of the baffling of flowing material, the powder agglomeration of large specific surface falls apart to form grains, and the total surface of the grains is moisturised, i.e. hydrated. By means of the hydromechanical mixing apparatus, in the case of the materials mentioned above, much better agitation than that in a mechanical mixing apparatus can be accomplished.
- the hydromechanical mixing methods utilise the kinetic energy of flows generated gravitationally and/or by pressure.
- gravitational flows the mixing of fluid and solid phases is carried out in the gravitation space by means of baffle elements installed in a fixed way in the gravitation space, while in the case of applying pressure generated flows, the energy required for agitation is created by the pumping of the fluid.
- a gravitational hydromechanical mixing apparatus is described, known as "hydromix", and used for producing thick slurry.
- a schematic view of the mixing apparatus is shown in Fig. 1.
- the dry bulk flyash flow introduced gravitationally through a hopper 3 in the direction of arrow b collides with the water/slag-slurry flow arriving under pressure from an inlet pipe 10.
- a conic baffle member 8 in the mixing space 1 the mixture is collected in a reservoir 2 in the bottom part of the mixing space 1 , by gravitational flow.
- One part of the mixture is delivered from here by a pump 6 through a pipeline 7 to a disposal place not shown in the figure, and the other part is returned by a circulation pump 4 through a circulation pipeline 5 to the mixing space 1 so that a higher kinetic energy is available for mixing.
- the air space in the mixing space 1 enables the precipitation of the gas/air bubbles and gases developed during the mixing process, and they escape from the mixing apparatus through a venting pipe 9 during the baffling of the solid and fluid phases.
- a further disadvantage of the approach above is that upon the baffling of solid and fluid materials, some of the powder particles start to float in the mixing space. The collision of floating powder particles with the fluid flow can only be ensured with difficulty, so the floating powder particles escape to the environment through the air space of the mixing apparatus, and so the mixing apparatus becomes a pollution source of the ambient atmosphere.
- the object of the invention is to create a hydromechanical mixing apparatus for producing a mixture of powder or granular state material and fluid, in which a relatively small mixing space without costly fittings is available for ensuring the kinetic energy necessary for intensive agitation and in which the mixing of the floating powder particles precipitating in the course of mixing is also ensured.
- the invention is a hydromechanical mixing apparatus for producing a mixture of powder or granular state material and fluid, the apparatus comprising at least one mixing space, a hopper for introducing the powder or granular state material into the mixing space, an inlet pipe for introducing the fluid into the mixing space, circulating means for returning at least one part of the mixture into the mixing space and a pump for delivering the mixture through an outlet pipeline.
- said at least one mixing space comprises an upper mixing space and a lower mixing space located one below the other, the upper and lower mixing spaces being connected by a conducting pipe having a cross section smaller than that of the upper mixing space
- said circulating means comprise a first circulating system for delivering one part of the mixture from a bottom part of the lower mixing space into the upper mixing space, and a second circulating system for delivering another part of the mixture from the bottom part of the lower mixing space into the lower mixing space.
- the kinetic energy necessary for mixing can be provided without having to use large volume mixing tanks.
- the first circulating system comprises a first circulating pipeline having an end protruding into the upper mixing space, said end being divided into jet pipes arranged in a way symmetrical to an axis of the upper mixing space and directing mixture jets into a space confined by the conducting pipe, and the first circulating system comprises a first circulating pump delivering an amount of the mixture so that the mixture jets fill up the total cross section of the conducting pipe.
- the second circulating system comprises a second circulating pipeline having an end arranged in a way introducing the mixture tangentially at one or more locations into an upper part of the lower mixing space.
- the mixing apparatus further comprises a baffle member located in the lower mixing space below the conducting pipe, said baffle member having a baffle surface with a conic shape or with a shape of increasing steepness towards its tip. Making use of the kinetic energy of the mixture flowing downwards, the baffle member - through the baffling effect - improves the rate of mixing.
- the upper mixing space is shaped axially symmetrically in a way narrowing downwards
- the inlet pipe is connected tangentially to an upper part of the upper mixing space
- the hopper is connected in the direction of the axis of the upper mixing space to the upper part thereof
- the outlet pipeline is connected to the second circulating system
- the lower mixing space is fitted with a venting pipe for exhausting gaseous materials.
- Fig. 1 is a schematic view of the known mixing apparatus
- Fig. 2 is a schematic view of a preferred embodiment of the inventive mixing apparatus
- Fig. 3 is a cross sectional view of the preferred embodiment in Fig. 2 taken along plane A-A, facing the direction of the arrows, and
- Fig. 4 is a cross sectional view of the preferred embodiment shown in Fig. 2 taken along plane B-B, facing the direction of the arrows.
- the mixing of the powder or granular state material and the fluid takes place in an upper mixing space 11 , in a lower mixing space 12 and in a space 13 confined by a conducting pipe 14 connecting the upper and lower mixing spaces 11 , 12.
- mixing spaces 11 and 12 and space 13 are shaped axially symmetrically with a common axis.
- the powder or granular state material flows through a hopper 15 in the direction of arrow b into the upper mixing space 11.
- fluid is introduced from a fluid tank 27 by a pump 25, through an inlet pipe 26. Tangential introduction is advantageous because the incoming fluid flushes the powder settling on the inner casing of the upper mixing space 11.
- baffle member 16 In the lower mixing space 12, below the conducting pipe 14, a baffle member 16 is located.
- the baffle member 16 is of a conic shape, but it can also be formed with a baffle surface of increasing steepness towards its tip.
- the mixing space 12 includes a venting pipe 17 for exhausting gaseous materials.
- One part of the mixture collected in the bottom part of the lower mixing space 12 is delivered by a first circulating system comprising a first circulating pipeline 21 and a first circulating pump 18 into the upper mixing space 11, and an other part of the mixture by a second circulating system comprising a second circulating pipeline 22 and a second circulating pump 19 to an upper part of the lower mixing space 12.
- One part of the circulated mixture is delivered by a pump 20 through an outlet pipeline 23 connected to the second circulating system after the second circulating pump 19.
- the first circulating system delivers approx. five times the volume delivered by the pump 20, and the second circulating system delivers two or three times as much.
- An end of the first circulating pipeline 21 protruding into the upper mixing space 11 is divided into four jet pipes 24 for ejecting the mixture as shown in Fig. 3, said jet pipes 24 being located symmetrically to the axis of the upper mixing space 11 in a way that they direct their mixture jets to the space 13 confined by the conducting pipe 14.
- This jet pipe arrangement surrounds the powder or granular state material flowing in through the hopper 15.
- the diameter of jet pipes 24 is 30 to 50 mm.
- the amount of the mixture delivered by the first circulating pump 18 in the first circulating system is preferably selected in a way that the mixture jets fill up the total cross section of the conducting pipe 14. In this way, a suction effect is imposed by the mixture jets in the upper mixing space 11 , to make sure that floating powder particles precipitating from the powder or granular state material are moved in the direction of the mixture jets and so they are mixed with the mixture flow.
- a suction of such an extent must be generated that the powder particles remaining floating after the baffling of bulk powder or granular state material and the circulated mixture jets are directed to the mixture jets by the suction.
- An appropriate suction effect is accomplished in the preferred embodiment depicted if in the space 13 the flow rate of the mixture is between 6 and 8 m/s. Without the suction effect, the floating powder particles not mixing with the mixture jets cling to the inner surface of the mixing apparatus, thereby gradually blocking the air space and the hopper 15 leading to the mixing space 11.
- the suction effect is also facilitated by the mixing space 11 having a funnel shape narrowing downwards. The suction effect so generated keeps under suction the air space of the funnel- shaped mixing space 11 , the hopper 15 ending in the air space and the inlet pipe 26.
- the baffled mixture flowing through the conducting pipe 14 still has a significant amount of kinetic energy, which could be utilised in order to ensure a better mixing and for removing the gas and air from the mixture.
- This kinetic energy is utilised in the lower mixing space 12 having a gravitational air space below the conducting pipe 14, in a way that the mixture flowing downwards through the conducting pipe 14 collides with the surface of the baffle member 16, so that it loses its kinetic energy in the course of intensive mixing, being splashed apart in the upper part of the mixing space 12, and reaching the lower mixing space 12 by gravitational flow.
- the second circulating pipeline 22 is introduced in a tangential direction into the upper part of the lower mixing space 12, as shown in Fig. 4.
- the mixture flow introduced in a tangential direction facilitates the comminution of larger grains, and as a result of centrifugal force it generates, the gas and air bubbles escape from the mixture. To this end, of course it is necessary to provide a gravitational field and the removal of escaping gases and/or air from the mixing space.
- the mixing apparatus according to the invention has been described for mixing powder or granular state material and fluid.
- the mixing apparatus can be used advantageously for producing thick slurry, when in a relatively small mixing space, the intensive mixing of slag and/or flyash, and water or thin slag slurry is performed without contaminating the environment.
