Definitions
- the invention relates to a ner driving for granulating and comminuting molten material and regrind, and to a device for granulating and comminuting blast furnace slag, clinker or the like, in which molten slag is cooled with water to form a glass phase.
- Molten blast furnace slag is usually granulated with the help of water in order to obtain an amorphous product which is in the glass phase, i.e. a metastable phase.
- a product can be added to cements as a hydraulically active component. With such a procedure, the heat of fusion of the melt flow is converted into a low-temperature heat of water and cannot be used any further.
- the heat of slag melting is used thermodynamically and technically only to a very small fraction, the energy originally contained being used essentially to convert the energy originally contained in the form of the metastable Save the glass phase of the end product, and prevent conversion to a stable crystalline state.
- the invention now aims to provide a method of the type mentioned at the outset with which the heat of fusion of slags is thermodynamically significantly better to use and to design the usually required grinding effort in the event of further use as a cement aggregate or for grinding clinker for the production of cement in terms of energy efficiency.
- the object of the inventive method is essentially that the melt is brought into a mixing chamber with compressed air, that water, steam and / or air / water mixtures are injected into the mixing chamber and that the evaporated water together with the solidified slag
- a diffuser is ejected.
- the fact that the melt is introduced into a mixing chamber with compressed air and water, water vapor and / or air / water mixtures are injected into the mixing chamber results in a rapidly expanding dispersion of solidifying molten material, whereby
- the expanding gas stream is expelled through a diffuser.
- the gas flow entrains the particles solidified into amorphous slag glass with an extreme increase in volume, the thermal energy being converted into kinetic energy which causes a directed flow of the formed
- the pressure in the mixing chamber essentially corresponds to the flow losses of the strongly superheated steam formed.
- the heat of the slag is mainly converted into flow energy, and the amorphous slag
- the high kinetic energy can subsequently be used directly for the comminution of oversize grain, for which the method is advantageously carried out in such a way that the exit jet of the diffuser hits a baffle plate or an exit jet
- n of another diffuser is directed. Due to the collision with further particle streams flowing out with high kinetic energy, or else with a baffle plate, the kinetic energy is used to reduce the energy expenditure for the grinding process, and there is thus a much more extensive use of those contained in the melt Heat than was the case with known methods. Due to the rapid increase in volume and the resulting expansion in the direction of the outlet opening of the steam diffuser, a negative pressure can be formed in the region of the maximum flow rate, so that the metering of additives is made possible here using an injector effect. The process according to the invention is thus advantageously carried out in such a way that further regrind or additives are introduced between the mixing chamber and the diffuser via an injector.
- the heterogeneous fluid which consists of a mixture of water vapor and solid particles, flows through the steam diffuser, whereby the flow velocity is reduced accordingly in order to avoid uncontrolled further expansion after the diffuser ignition, the process is advantageously carried out in such a way that the exit velocity of the steam jet from the diffuser is set to be less than the speed of sound.
- the steam formed in the process according to the invention has a significantly higher temperature level than conventional slag granulating devices, and the steam temperature can be recovered in a conventional manner.
- the procedure is such that the steam formed is drawn off and passed through a heat exchanger, and that the condensate is returned to the mixing chamber, so that the water used can also be circulated.
- the device according to the invention consists essentially in that a line for molten slag is connected to a mixing chamber, that lines for water, water vapor and / or water / air mixtures open into the mixing chamber, that a diffuser is connected to the mixing chamber, and that the outlet opening baffles or further outlet openings for accelerated particles, the axis of which intersect the axis of the outlet opening of the diffuser, are arranged.
- the blast furnace slag granulate formed can with such a device not only in the amorphous glass phase are solidified, but at the same time, using the kinetic energy resulting from the thermal energy by conversion, are comminuted to such an extent that a further grinding process can be omitted.
- the thermodynamic energy of the slag melt is thus also immediately used for the grinding process.
- the device according to the invention is further developed so that the line for molten slag over
- the water jet can be pushed radially into the mixing chamber, for example.
- the design is such that an injector chamber with a smaller effective cross-section than the outlet opening of the diffuser is arranged between the mixing chamber and the diffuser, to which a line for further regrind or additives is connected, so that under
- the design is advantageously made such that a steam suction device is arranged after the outlet opening of the diffuser, the steam suction line with at least one heat exchanger connected to what that
- FIG. 1 denotes a slag melting vessel, from which a slag melt 2 is drawn off via a tap opening 3.
- the tap opening 3 opens via an annular nozzle 4 into a mixing chamber 5 of the device according to the invention for granulating and comminuting the slag, which is designated 6 overall.
- Compressed air is introduced into the ring nozzle 4 via an external annular channel 7, as a result of which a homogeneous dispersion of the slag jet in the mixing chamber 5 is achieved.
- Lines 8 for pressurized water also lead to the c mixing chamber 5.
- the pressure water pushed into the mixing chamber 5 via the lines 8 expands at high speed and can flow out in the direction of the arrow 9.
- flow energy is imparted to the granulated particles, so that the particle stream with the steam can leave the outlet opening 10 of a steam diffuser 11 at high speed and thus high kinetic energy of the particles contained.
- a storage container 14 is provided for the metered introduction of additives or additives, and a dosing screw 15 is arranged in the feed channel to the injector chamber.
- a further diffuser mouth 16 of a further steam diffuser 17 is indicated schematically, to which another device, essentially the same as the device 6, is connected.
- the axes 18 and 19 of the particle streams leaving the diffusers 11 and 17 intersect one another in a granulate comminution section, indicated schematically by 20, whereby an intensive conversion of kinetic energy as grinding energy takes place, whereby the particles are further comminuted.
- the baffle plate designated by 21 also serves the same purpose, onto which the particle streams, possibly deflected by particles from the second unit in each case, impact and are comminuted using the remaining kinetic energy.
- the ground material designated 22 can be used directly as cement or cement aggregate, oversize which may still be present can be returned to the injector chamber 12 via the line 13.
