Description of the invention: [Technical field to which the invention pertains] ~ The present invention relates to a method for pneumatic transportation of solids in accordance with the preamble of the scope of the patent application, in which the patent application is applied in accordance with paragraph 5 The method of the device. [Prior Art] In many technical fields, how to transport solids through a pipeline system is important. This result allows the transport to take place in the closed conduit, where the material to be transported - initially becomes as small as a deer, and in particular will be shredded as to/and then mixed with the transport medium or transport medium. It is a ritual transport medium, especially composed of transport gas, such as a factory or a flue gas with a relatively high concentration of carbon dioxide. = The production of the transmission is determined by the starting point and the end of the transportation section. The effect of the transmission is also determined by several parameters ', the fineness of the solid and the distribution of the particle size, the loading situation 'viscosity and transport The temperature of the medium. The hood is known to be related to the production of iron in the blast furnace. The hot air that is entangled by the action of blasting coal is blown into the blast furnace, and the above-mentioned coal ash is used as an alternative. Reducing agent / alternative fuel for coke, that is, according to the pulverized coal injection (pci) program or other processing procedures, used to control the consumption of coke, especially to reduce the consumption of coke, and at the same time, to the phase (4) The furnace operation stability and the efficiency of the blast furnace are increased. Yu Yu, for example, Paul Furth SA, published in May 2002, catalogue of crushed coal injection systems, which describes the crushing equipment for coal ash in accordance with the smashing coal 1312334 And the equipment used for gas and the type of injury is also added, and the processing technology is based on the pressure of the inertia (the requirements of the king's requirements, *55 ^. Mole), at least In the state of the cylinder warehouse W. The mountain is seven, 'the pneumatic transport of the fire is almost a method that is said to produce only non-wheels, especially in the pipeline μ ^ ^ ^ . Abrasion and the gas consumption of the thick a transport method is very low compared to the thin layer transport method. In a pulverizing and drying equipment, the appropriate (four) machine begins to smash a corresponding steam in the smashing and dry Then, it may be that from a round of two coal will enter the injection equipment and into a distribution container = 1 the container itself will be subjected to the pressure exerted by the gas. Subsequently, the problem of mobility occurs in the equipment ° ° within the exit area and extra The appearance of the tube; the subsequent tube coal ash can be transported by adding a wheel to prepare the gas/forward wheel gas (for example, nitrogen). The result is that the phase::: road 'distribution container is too high The pressure, the coal is applied internally = pressure and is transported to the subsequent use point. When the coal ash is/into the two furnaces, the above gentleman's dip - ^ 'π fruit is formed by the blast furnace The operation of the blaster. The measurement or use of the coal ash (that is, the flow rate of the coal ash) is controlled by changing the pressure gradient at the conveying section or changing the location of the conveying section. In the U-lt; hard 虱 body flow obtained. In addition, can also be combined with the pipeline control valve 'the free passage opening of these pipeline control valves can be adjusted. Then 'a control room will be combined to have flow measurement 1312334 Lili%, a control loop can be formed. Known problems will occur in the transportation of coal ash (the coal ash). This type of problem is injected into the furnace and the type appears in the main... Is vibration or blockage In the section, (4) ":. If the control valve is combined to vibrate in the transport area, and the = part: r is enough to be transported in an uncontrolled manner, the control valve is also easily blocked. The material properties of the material (especially the degree of graininess and the size of the particles) are very important for the problems and subsequent problems that occur, and the specific material properties are often not fully evaluated. The performance is strong, μ Mobility and transport and control are different from each other. Therefore, compared with other coals, the viscosity of the cockroaches is higher. The problems related to pneumatic transport of coal ash in the & road can lead to post-procedures. And the use of money to continue to use the location point has a considerable shortcomings. Because of the knowledge of the coal injection rate of gray ash and the control of the entire coal ash flow: sentence s greatly affect the effect of coal ash injection, so, the impact of magic, The economics of the operation of Lu. Problems in the injection line can have a negative impact on the know-how of the entire blast furnace, which in turn leads to increased production costs and reduced quality of the chain iron. SUMMARY OF THE INVENTION I. The object of the present invention is to provide a method and an apparatus for modifying the condition of a pneumatic carrier of a solid within a & line, and subsequent processing procedures

In particular, it is possible to optimize the transport situation of coal in the blast furnace injection equipment and to reduce the possible errors and problems. According to the present invention, the method for obtaining the characteristics of the above-mentioned objects is prepared by the B M i b τ 。 patent target. This (4) bis and the scope of the application by the characteristics of the application of the scope of the sixth paragraph and the description of the drawings. In the case of the heart, the invention is based on the fact that by adding a certain proportion, it is possible to cover the y· & other materials ‘, . In the official road, the solid pneumatic transported the performance results of the 裎mi system. It is particularly advantageous to transport and control additives with viscous solids to add solid or dust to the other. It has been: If the two materials have considerable density differences, they are mixed with the additives. The body agent can be used for the flowability of β. The addition of the two materials or a mixture of materials. From the point of view of this method: the addition force: the agent can be added before, during or after the pulverization of the solid (four) In the case of a solid shovel, I add an additional additive to the pulverized type additive. The additive is added to the front or part of the transport section and is added to the starting point of the transport line. Upstream, used to control the solids flow of solids at different injection lines. "The downstream of the W distribution mechanism is about transporting coal ash in the pipeline, especially in the blast furnace blast inlet. In the above, it is known that the fluidity of the finely pulverized coal can be greatly improved by the mixing action of the material containing iron/iron oxide (especially the shards). It is known that the improved transport characteristics of coal ash can lead to significant improvements in the operation of the metering or control room 1312334. This metering is used, for example, in coal ash injection equipment with a single factor control method, which has an independent, continuous measurement method and control of coal ash flow in the injection line to inject coal ash into Inside a blast furnace blaster. Due to the single element control method, coal is distributed very evenly around the blast furnace. In addition, the specific consumption of gas or several other transport gases in coal ash injection equipment with a single factor control method is quite low, and this result also contributes to the optimization of the operation of the South Furnace. Metering valves and control loops in individual different coal ash injection lines can also be used in the injection equipment where all of the coal ash flow is distributed to individual injection lines in a controlled manner. In such an apparatus, a flow measuring mechanism and a coal ash metering valve are installed in each of the injection lines located downstream of a static distributor. The advantages of the single element control method, or the use of metering and control valves in pneumatic transport systems, are able to overcome operational problems due to blockage of valves and injection lines, as well as to address vibrations in control loops and vibrations due to uncontrollable vibrations. The lack of bringing. Due to the new combination of flow improvers and solids, the above defects can be avoided. This result has been confirmed by the test effect of coal ash and mixed crushed chips. By mixing the crushing debris, the transportation gas with coal ash can be more uniformly filled, and the control valve and the transportation section are blocked or blocked, and if it is injected into the injection When the coal ash in the equipment is mixed with the material of the smashed debris 1312334, it will be greatly reduced. ...the situation in which the control circuit of the main equipment is faulty except for the crushing Η# can be mixed with other ferrous materials such as ash, and the above-mentioned coal ash is also mixed with dust such as flue gas and good agent dust. The agent ash is particularly hearty = tower deposits and compartmental deposits. The final use of the device or the use of the good additive is an effective way to improve the improvement of the good (4), and the flow can be applied to the dust of the sample if it is used in subsequent high-level applications. ...the rolling debris in the program and the oxidation of iron/iron

The important advantage of the two-two scheme is to reduce the loading of the transport medium C transport gas, which leads to the result. The coal ash metering or control knot in the injection equipment is added to the coal ash, which also helps to accelerate the burning rate in the horse oven processing program. The advantage of being a stricter one is that a considerable amount of bismuth P sheets and similar materials are produced in the rolling processing operation and are rationally and effectively employed by their own mixing with coal ash. It is known that the mixture of moving coal ash debris has a content of reported fragments of 3 to 15 * percent, a bulk density of about 7 metric tons per cubic meter, and a degree of 80 to 70 percent less than 9. Micron, these characteristics can not be separated during the pneumatic transport operation. Improved aerodynamic motion operations can effectively increase the production of coal ash.

However, it must be appropriate to: - a mixing device (for example A mixture of coarse coal fragments is produced in a mixing bed or a mixing drum, and the mixture is fed to a powder mill. 1 Coal or some other reducing agent or reducing carbon mixture with a piece of material or some other containing The integrated comminution of iron/iron oxide materials can be carried out in all suitable comminution systems and powder mills. - The integrated comminution in a Loesche roller pulverizer is particularly cost effective and reasonable. Efficiency. Known specific parameters that affect the long order of a pulverization process 'for example, the specific power demand and the power of the pulverizer are 1312334 = will be affected by mixing about 3% to 15% of the smashing debris to the pit 2 2 Or the negative effect brought by the mixture of coal and petroleum coke.
