INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a process for treating ash, particularly for combustion of fossil fuels in a dust-phase steel furnace (for example, in an energy production plant and the like) Apparatus and method for light ash obtained by co-combustion with CDR or biomass [Prior Art] The current law governing the use of light ash in cement and concrete production orders limits its particle size analysis and the percentage of unburned material. The limit values are determined and applied so as not to change the characteristics of the final product obtained. In order to produce cement, it is necessary to use a large amount of natural resources, especially limestone and volcanic ash, which are obtained from specific pits. The limestone and volcanic ash mixed into other mineral components are burned in a furnace of a cement plant to obtain cement clinker which is appropriately ground to become a real cement. The production of one ton of clinker produces about one ton of c〇2. Adding less than 5% by weight of unburned material and good quality light ash to cement clinker up to a percentage of 30%» By replacing this, millions of tons of light produced by solid fuel in the boiler can be reduced annually The percentage of unburned 2 substances present in the ash will depend on the fuel used, and the rent of the bucket / 1

The main conveying line 1 〇 8 of the light ash in the device 107. Conversely, the other end of the line 4 downstream of the flow in the line 2 and downstream of the second conditioning and/or shutoff member 42 is connected to a population of means 5 for separating ash, such as a cyclone type device, which facilitates the delivery of air The flow is separated from the ash and the air is fed to the main transport s line 108' of the factory by means of an outlet line 6 which is preferably also equipped with an adjustment and/or shut-off member 61.

Represented by 9 and having a plurality of lines for feeding the hot digas, the plurality of lines are disposed below the conveyor belt 81 and each corresponding to a lateral opening 82 of the associated outer casing 83. In an embodiment of the invention, such The pipeline is six, which are denoted by reference numerals 丨丨 to 16, respectively, and each of which preferably has individual components for shutting off and/or regulating the flow (one of which is for example indicated at 121). The temperature of the air is preferably comprised in the range of about 3 Torr to 500 ° C. The air can be collected from the external environment and introduced into a specific exchanger (not shown in the embodiment of the invention) at a desired temperature. And then by means of The fan, i 〇 denoted, is sent to the device 8. Preferably, when necessary, the hot air necessary at the inlet of the device 8 is collected by a line of preheated combustion air exiting the air/mist exchanger 1 〇2. The entire configuration stratifies the hot air fed by lines 11 through 16 across the ash located on the conveyor belt 81 to pass through the dedicated slots of the conveyor belt 81 and thus construct a fixed bed or fluid bed depending on the traversing speed of the ash layer.

Alternatively, the residence time is determined in advance by a particular pre-configuration of the section. 12 201105909 Reactivation device 8 The general operating principle will be described as follows. The basic technique of the present invention is to carry out combustion development by means of a series of basic stages. In the simpler formula of the semi-detailed dynamic mechanism of carbon combustion, the basics related to the following reactions must be considered. Process: (i) Cf + 〇2 _> C(O) (Reaction of carbon to form an oxidized surface complex by chemical adsorption of atmospheric oxygen) (ii) C(〇) + 〇2 C0, C〇 2 + c (Exchange reaction of oxidized surface complex), and (!ϋ) C(O) CO ' C02 + Cf (desorption reaction of surface oxides with Ik forming CO and C〇2). Oxidized surface of reaction (111) The desorption process of the complex is slow at moderate temperatures and extremely fast at elevated temperatures, which is unique to carbon combustion systems. According to reaction (i), the reactivation treatment in unit 8 promotes unburned carbon in the gas stream. Chemical adsorption of available oxygen. Once the chemical adsorption is achieved, it remains stable. According to reactions (ii) and ((1)), in this mode, the right unburned carbon should be at the typical temperature of the combustion chamber. It will burn with the same initial reactivity in order to complete the oxidation process of the carbon thus activated. 0. Therefore, the basic concept of the invention is to pre-oxidize the volatile ash portion with a higher content of unburned material and then enter In the combustion chamber, the purpose is to re-enter the ash containing the extensively oxidized carbon into the combustion chamber at a pre-oxidation of about 30 (TC to 500). The temperature at that temperature is effectively carried out with relatively fast kinetics in a dedicated device such as a device.

The extraction device, indicated generally at 18, can in turn be coupled to a suction member 2〇1 provided on the air suction line 2〇: in the case of the above-described line 7 connected to the introduction device 8, the dust removal device” insertable member Between 18 and line 20 to dispose of the ash separated by the $ gas stream. * Even on each of the pipelines described at the end of this article, and in detail on line 2〇 and between the insertion of the skirt 18 and the precipitator 19 The pipe and the channel between the plug-in precipitator 19 and the line 7 provide corresponding means for shutting off and/or regulating the flow. The extracted air can be fed from the suction line 2 to the line for passage through the flue. Discharged, or fed directly into the atmosphere or even to the air tank of the plant 100 for the inlet of the combustion chamber 101. The reactivation device is disposed downstream of the conveyor belt ash stream. 8 has a primary discharge location 85, which preferably has At the end of the hopper 81, the line 21 located on the outlet line 21 may have means for shutting off and/or regulating the flow (e.g., the rotating unit 23 in the case of water cooling in 201105909) to improve its efficiency. Finally, the outlet: line collection On the final transfer line 24, the latter preferably feeds the reactivated ash to the combustion chamber 1〇 on the level of the intermediate burner plane and typically by pneumatic transport. Of course, the latter line 24 can also be used. The individual components for the cut-off and/or adjustment of the relevant flow. The above selection of the location for introducing the reactivated ash into the combustion chamber is governed by the following cranes: allowing sufficient residence time in the combustion chamber to allow for the completion of the pre-fill The oxidation of the treated unburned material is then entrained by the combustion fumes with lighter particles and the particles escaping from the entrainment of the combustion smoke fall by gravity to the bottom of the steel furnace. The specific example of Figure 3 is due to the different construction of the reactivation device. Unlike the appropriate descriptor, here is indicated at 80. The apparatus 80 includes a storage tank that constructs the ash fluid bed or fixed bed by means of a reactivated air stream. The rupture 80 typically operates intermittently. a member 9 for activating hot air and a member for constructing the necessary thrust to introduce the air in a specific case (for example, a pressure fan 10) (completely similar to them) Illustrator) is coupled to device 80. The device 80 is provided in communication with a possible dust removal device 19 in accordance with a mode substantially similar to the mode that has been described with reference to the first embodiment. Device 80 is further similar The lower ash outlet is provided on the outlet line 211 of the line 21 which has been described. The specific example of Fig. 2 is instead different from Fig. 1 in the following aspects: insertion of a grading/separating device between the introduced device 5 and the inlet of the reactivation device 8 25 and downstream of the powder outlet of the dust removal device 19 already described.

The presence of the separation device 25 is especially important even when the main plant 100 has a mechanical filtration system (e.g., a bag filter instead of an electrostatic precipitator). In fact, as already reminded above, it has been known that the choice of ash having a high content of unburned material found in the last region relative to the direction of travel of the smoke in the electrostatic precipitator has been determined by the ash resistivity and the contained The percentage of burning matter is proportional. In a filter that was mechanically trapped instead, this separated and unburned material was not found to be diluted based on the total flow of the captured ash. In the case of a mechanical filtration system, it thus results in a condensed phase which can reasonably provide a higher ash content of unburned material. Therefore, the higher ash flow rate of the unburned material to be reactivated may allow for optimization of the size of the reactivation and recirculation system in the boiler. Figure 4 shows the different plant configuration, wherein the bag filter is indicated at 109. In this case, ash feeds are provided from each of the outlet sections of the bag filter cartridge 9 itself, in the illustrated embodiment, four segments of feed and are indicated by reference numerals 110 through 113, respectively. Again, in the illustrated embodiment, four dedicated collection lines are then provided, indicated by reference numerals 3A through 33, respectively. The apparatus 25 appropriately grades the ash having a higher content of unburned matter, thereby avoiding the treatment of a very light ash. The device 25 can be of the triboelectric, aeraulic or equivalent type, which allows for the selection of the ash shunt to be reactivated by separating the ash shunt to be reactivated from the one to be transferred to the silo 107. . As mentioned earlier, in Taili (you can provide adjustment and control systems in all specific examples, which ensure that the operation is carried out automatically. At this point, it should be better understood, according to the specifics described above By way of example, the present invention provides an apparatus for recovering, activating, and recycling light ash trapped by a system for treating smoke in a combustion chamber. 'It should be understood that if the reactivated air flow rate is comparable to the flow rate of the ash to be treated In any case, the choice of how to dispose of the reactivated air downstream of the ash to be treated and where it is collected depends only on the ease of work and waste. In addition, the amount of oxygen required for reactivation of unburned substances is less. Therefore, the reactivated air stream may even be contaminated and have waste heat generated by the process, which makes the proposed application slightly more expensive in terms of investment and additional operating costs. It should be understood that ash reactivation may not be self-contained by itself. Extraction from a system that burns smoke, but in principle at any stage after its extraction from the combustion environment and possibly re-entry into the combustion environment Occurs before combustion, for example downstream of a silo for collecting light ash. Furthermore, the ash delivery can even be mechanical rather than pneumatic, for example mechanically transporting ash, which can be used for system output for processing fumes and partly The delivery is as far as the combustion chamber. Finally, it should be understood that the subject matter of the invention is also a reactivation method preferably constructed corresponding to the mode of operation of the apparatus and plant as defined above and in the scope of the following claims. The invention has been described with reference to the preferred embodiments. It is understood that there may be other specific examples which are the subject matter of the invention as defined by the scope of protection of the accompanying application.
