The shape of the body 45, Ding Zhu (4) may be convex (four), but may also form a trapezoid or a quadrangle. It is important that the shape of the surface of the unburned carbon may be worn between the wearer body and the inner wall surface of the sinker. Further, the interval (10) between the tip end of the mixing blade 36 and the inner wall surface of the transfer groove 33 is preferably in the range of 2 to 100 _ or 5 to 5 Å. Since the surface modifier is required to be manufactured with high precision, if the gap between the tip end of the blade % and the inner wall surface of the agitation vessel 33 is less than 2, the manufacturing cost becomes high. Further, when the gap between the tip end of the spoiler 36 and the inner wall of the spoiler 33 exceeds 1 〇 0 m m, the effect of surface modification of unburned carbon is reduced. Further, it is preferable that the agitation blade 36 is provided with a stirring force (stirring power) of 1 〇 to 1 〇〇 Kw/m 3 per unit mass, preferably 30 to 5 Kw/m 3 . Further, when the stirring power of the stirring blade 36 is less than 1 〇 Kw/m3 per unit of the slurry, it is difficult to change the surface of the unburned stone. On the other hand, when the stirring power of the stirring blade is more than 1 〇〇 Kw/m3 per unit of the slurry, the surface of the unburned carbon can be modified, but the power consumption is greatly increased. Moreover, since it also increases the friction inside the agitation tank, it is not economical. Further, the stagnation time of the slurry is set to 〇·PiO, preferably 〇·5 to 5 knives. When the stagnation time of the slurry is not full, it is difficult to carry out surface modification of unburned carbon. On the other hand, when the stagnation time of the slurry exceeds 10 minutes, since it does not further improve the surface modification of unburned carbon, it may become uneconomical by increasing equipment cost or running cost. The surface modifying device 30 is composed of a plurality of (three in the figure) 312XP/invention manual (supplement)/96-04/96100754 n 200829336 surface modifying machine 31, 38 connecting pipe 32 And the string: far: the surface modifier 31 is provided with a pump at the trailing end (3rd). Moreover, the surface modification device 30 is in the front stage, that is, by the bypass path 39 moved back by the first machine 31, the modified slurry can be modified in the third, the third surface modification machine 31a, The λα surface modifier 31c bypasses. The inlet 40 of the bypass is connected to the wide-area passage 39 41 ^ ^ connection g 32 , and the outlet U of the bypass passage 39 is broken to the connection pipe 32 of the connection pipe 32, and the connection pipe 32 is in the bypass path μ = path 39, There is valve 42, 2 > 43. The further flow side of the connection point of the road 39 has a valve supplied from the surface modification device 3, and the slurry supplied by the surface modification device 3 is supplied with the foaming agent B. 5 η &...m low/3⁄4 μ(4) n 51 The hair has a stirring blade 61 inside. $ Blowing agent to use 峨 (4_methyl-2-pentanol, Pa... such as carbino", etc. The amount of foaming is preferably 2〇5〇〇〇卿 or 100~圈卿. When the amount of the foaming agent is less than 2 〇, the occurrence of bubbles is insufficient. On the other hand, when the amount of foaming exceeds 5000 ppm, the cost of the foaming agent is increased. The recovery rate of the ash is reduced. Further, the excess bubbles contaminate the surrounding environment. In the subsequent stage of the adjustment tank 60, a pump 62 for supplying the slurry d" after the addition of the blowing agent to the flotation machine 70 is disposed. The flotation machine 70 can make the modified unburned carbon adhere to the bubble and float to separate the unburned carbon (froth) and the fly ash (tailing, taiHng) from which unburned carbon is removed, and A conventionally known flotation machine can be used. As shown in Fig. 6, the surface modification device 3 can be applied to a vertical type 312XP/invention specification (supplement)/96·04/96100754 12 200829336 multi-stage stirring tank 101. The vertical multi-stage stirring tank 1〇1 is composed of: a vertical stirring tank 102; and a plurality of sections are arranged on the inner surface of the stirring tank 102. a ring-shaped partition wall 1〇4; and a rotary shaft 105 provided at a shaft core portion of the agitation vessel 102; and a stirring blade 106 provided on the rotary shaft 1〇5 alternately with the partition wall 1〇4; In the figure, the symbol j 〇9 is the slurry introduction port, the 110 series slurry discharge port, and the gap between the stirring tank j and the mixing blade 〇6, and the stirring force of the stirring blade i〇6 ( The stirring power, the stagnation time of the slurry, and the like are set to be the same as in the previous example. Next, the action of the unburned carbon removing device will be described. The present invention uses the nature of the fly ash to determine the use number of the surface modifier in advance. For example, if the fly ash is relatively easy to be surface-modified (for example, fly ash from bituminous coal), the number of surface modifiers used is small, (the figure is 2), and the fly ash is difficult to surface-modified ( For example, in the case of general carbon fly ash, the number of surface modifiers is large (3 in the figure). Also, for the sake of convenience, the number of surface modifiers used in 2 stages is used. To explain this, in this case, the valve 42 of the bypass passage 39 is set to "on", and the connection is made 2 The valve 43 of 32 is set to "closed." In Fig. 2, 'flying ash a is supplied to the slurry preparation tank ι〇 and water c Π: into two bodies d. At this time, the concentration of the fly ash of the ferry, For example, it is modulated - new w /. This slurry d ' is supplied to the worksheet 12: the reformer 31a' but on its way 'adds both the amount by the collector tank 2 (for example, 〇.捕1 to 3.0 wt% (for flying stones)) The collector of the surface modifier and the collector e are imparted by the same speed (for example, '2G (M_n> m) agitating blades 36) Fried 312XP / invention manual (supplement) / 96-04/96100754 13 200829336 cutting force. The slurry d and the collector e to which the shearing force is applied to the first surface modifier 31a are supplied to the second surface modifier 31b to impart shearing force. Thus, the shearing force is applied to the slurry and the collecting agent, and the floating property of the flotation is improved in order to reform the surface of the unburned carbon. However, referring to FIG. 5(a) to FIG. 5(c) ) while explaining. As shown in Fig. 5 (a), when only the collector is mixed in the slurry-like fly ash, only the mixed fly ash a, the unburned carbon b, and the collector e are mixed in the water c. In this state, even if the slurry is supplied to the flotation machine, together with the collector, the amount of unburned carbon adhering to the bubble is very small, and therefore, the unburned carbon in the fly ash cannot be effectively removed by the flotation. However, if the surface is modified by applying a shear force to the slurry and the collector of FIG. 5, the dispersed particles of unburned carbon b, fly ash a, and collector e in the slurry are used. Transitional active energy occurs and the surface becomes oleophilic. Further, when the surface of each of the particles of the oleophilic unburned carbon b and the trapping agent e is adhered to reduce the surface energy of each other, the result of 10 is as shown in Fig. 5(b), in the unburned carbon b. The collector e can be attached. Therefore, when the flotation machine is used for flotation, as shown in FIG. 5(c), the unburned carbon b adhering to the collector e adheres to the bubble n and floats, so that the flotation of the unburned carbon b can be improved. The planktonity. The modified slurry d discharged from the second surface reformer 31b is supplied to the adjustment tank (10) through the bypass passage 39. Here, the tank 6 is adjusted, and only a predetermined amount (e.g., 20 to 5000 ppm) of a foaming agent f such as MIBC (4-mercapto-2-pentanol) is added. The slurry d" after the addition of the blowing agent f is supplied to the flotation machine 70 and is floated. 312XP/Invention Manual (Supplement)/96-04/96100754 14 200829336 Bubble containing unburned carbon (not The combustion carbon) is solid-liquid separated by a filter press (not shown) to recover unburned carbon c. The water dehydrated by the filter is supplied to the brewing tank by a pump (not shown). 10, and then added to the new fly ash. On the other hand, the tailings (flying ash) j from the flotation machine 70 is used for solid-liquid separation by a solid-liquid separator (centrifugal dehydrator) not shown. 'Using ash as a product and being used as a cement mixed material, etc. (Industrial Applicability) The present invention is applicable to fly ash which is self-burning coal-fired power plant or fluidized bed burning furnace BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a block diagram of an apparatus for removing unburned carbon in fly ash according to the present invention.
