Effectively achieving thermal points', it is possible to perform carbonization without distinguishing between the drying and thermal decomposition of the sludge. However, it is better to set a dry temperature zone and a thermal decomposition shirt separately. That is, the carbonization of the sludge. In the process, because the drying temperature of the organic matter is different from its thermal decomposition temperature, when the heating zone is set at two or more stages, the carbonization of the sludge can be effectively achieved. If the incineration treatment method according to the conventional technology is sufficiently high at 80 ° C or higher The incineration (combustion) conditions of oxygen supply can be inferred (results of carbonization treatment) as follows: pulp and other substances are burned and 'silicon dioxide' and the like are melted and grown around the remaining carbon to form residues. The solid black band was then clay component of the original structure is destroyed.

Description of the invention (10) Although the organic matter can be burned simultaneously in the carbonization step in a way that can maintain the original state of the organic matter, the incineration is opposite, resulting in as far as possible the fire caused by the limitation of the sludge formation step. The silt is steamed to replace the water produced by setting the oxygen gas (air) in the required size. Better oxygen exists in the furnace for the heating of the mud. From the economic point of view, it is best to use the carbonization equipment that burns the oxygen (air) and the sludge to prevent hot air. The most preferable is the carbonization of the heating chamber for 5 carbonization heat. The heating of carbon and materials from the beginning of the implementation of carbon if there are aerobic organic matter, pigment-containing oxygen gas furnace gas input when the input is in the furnace gas or vapour, so that the carbonization of the carbonized carbon treatment gas storage Combustion temperature is not affected by (air) The temperature within the range that does not accompany the temperature of the atmosphere is difficult to distinguish from the carbon generated in the furnace. However, it is best to fix the carbonization and the calcium carbonate derived stone is in reverse, then burn. The degree of hope rises into the above oxygen. There is also a combination that will not increase the temperature when the result is thermal denaturation in the furnace. The method 'may be too good (the monoxide is turned into an oxygen-depleted state') because of the atmosphere contained in the mud. Therefore, it is better to prevent the lowest mud accompanied by hydrogen, which is the temperature of the volatile organic matter. Therefore, in the carbon to stop the sludge, the limit is used to quickly and benefit from the "-φ \\\ method. Although the lamp gas can be used to contact the sludge, the direct contact is good. The method is that although electric heating is also feasible, but it is heated by the combustion gas of oil or heavy oil. Direct heating is also possible, but because the mud contained in the hot air causes the silt to ignite and burn, it is better to install partition walls in this way. Therefore, the closed chamber which can restrict the inflow of air. That is, the heating furnace is connected between the sludge carbonization chamber and the carbonization h heavy structure.

Description of the invention (12) When heated by temperature, it can effectively improve the whiteness. In the decarburization-whitening room, since the temperature of the atmosphere in the furnace is set to 5,000 or more, the carbon derived from the organic matter contained in the carbide is oxidized, and the effective whitening of the white inorganic particles can be achieved. Decomposition-whitening is performed at a temperature lower than 45 0 ° C, and the treatment time becomes longer. If it is performed at a high temperature exceeding 丨 0 0 t, the melting and sintering of white inorganic particles will progress. Causes difficulty in fine pulverization after decarburization-whitening. In addition to this disadvantage, it also enhances the coloring tendency, so it is not suitable. Regarding the treatment time, it should be considered not only in terms of the form, quality, moisture, and carbon content of the carbide, but also in terms of economic effects and environmental aspects ^, but it is preferably about 30 minutes to 2 hours. Finally, when the carbide is decarburized and the whiteness of the white inorganic particles reaches 70% or more (preferably 80% or more), an inorganic particle suitable for a raw material for papermaking can be produced by using this. @ & In particular, the decarburization-whitening treatment step is also referred to as the calcination step. In the case where this step is carried out by a piece of processing, at a temperature of 450 to 6 50 ° C (preferably 5 0 ° C to 6 0 ° C) and 60 to 180 minutes in an oxygen-rich state, As a result, it can be inferred that the combustion of carbides occurred, and the inorganic components such as calcium carbonate, kaolin, and silicon dioxide were reused, and the extent of the problem remained. When the temperature is lower than 450, organic carbonization is difficult to progress, and when the temperature exceeds 65 ° C, clay formation is easily destroyed, so in order to obtain a stable recycled material knife The range of the processing temperature is adjusted to match the components of the papermaking sludge. In the decarburization-whitening treatment step, if the carbide is heated rapidly, it will become white.

527455 五、發明說明(14) 之場合,考慮到下述情況之影響:即碳酸鈣與煅燒高嶺石 起反應而發生白色無機粒子之溶融〜燒結。此等白色無機 粒子除了有使脫碳-白化後之微粉碎發生困難之不便之 外,亦有增強著色傾向之缺點,因此不合適。 雖然上述情況依碳酸鈣含量而不同,但為了在防止白色 無機粒子之炫融〜燒結之下,提高高嶺石之白色度,最好 能管理碳化物本身之溫度。但碳化物之局部性溫度變化係 難於測定。因此,較佳的是,在白化室設置溫度感測器, 以白化室之氣氛溫度可達到8 0 0 °C以下之方式,供給含氧 氣體(空氣),而以不致發生碳化物之自燃所引起之碳化物 (本身之)溫度之急劇上升之方式予以管理。又按,高嶺石 為屬於2八面體型1 : 1層狀矽酸鹽,其除了包括狹義之高嶺 石外,亦包括多水型之地開石(d i c k i t e )、珍珠陶土 (nacrite)、以及敘永石(ha 1 1 oy s i te ) o 由於要防止碳酸妈之脫碳酸’在脫碳後之白色無機粒子 會混有來自於泥之碳酸釣。因此,白色無機粒子之殘碳率 有時在脫碳-白化處理後亦顯示較高之數值。雖然有機物 由來之碳與碳酸鈣由來之碳難於區別,不過較佳的是,儘 量降低有機物由來之殘碳率。最好能將有機物由來之殘碳 率設定為1 %以下,藉以回收適於造紙之白色無機粒子。 為碳化物之加熱方法,亦有可能利用燃燒氣體來施行直 接加熱,但此項直接加熱引起熱風所含之未燃碳與白化之 白色無機粒子接觸,致使白色度降低,因此,最好能以於 泥不致與熱風直接接觸之方式設置隔牆。即,在脫碳—白527455 5. In the case of the description of the invention (14), the influence of the following conditions is taken into consideration: that is, calcium carbonate reacts with the calcined kaolinite and the white inorganic particles are melted to sinter. These white inorganic particles are not suitable in addition to the inconvenience of making micro-pulverization after decarburization-whitening difficult, and also have the disadvantage of enhancing the coloring tendency. Although the above conditions vary depending on the calcium carbonate content, it is best to manage the temperature of the carbide itself in order to increase the whiteness of kaolinite while preventing the white inorganic particles from sintering to sintering. However, the local temperature change of carbides is difficult to measure. Therefore, it is preferable to provide a temperature sensor in the albino chamber so that the atmosphere temperature of the albino chamber can reach below 80 ° C to supply an oxygen-containing gas (air) so that the spontaneous combustion of carbides does not occur. The resulting sharp rise in the temperature of the carbide itself is managed. According to another, kaolinite is a octahedral type 1: 1 layered silicate, which includes not only kaolinite in a narrow sense, but also water-based dickite, pearlite, and Syria Yong Shi (ha 1 1 oy si te) o To prevent the decarbonation of carbonic acid, the white inorganic particles after decarburization will be mixed with carbonic acid from mud. Therefore, the residual carbon ratio of the white inorganic particles sometimes shows a higher value after the decarburization-whitening treatment. Although the carbon derived from organic matter is difficult to distinguish from the carbon derived from calcium carbonate, it is preferable to reduce the residual carbon rate derived from organic matter as much as possible. It is best to set the residual carbon ratio from organic matter to 1% or less, so as to recover white inorganic particles suitable for papermaking. For the heating method of carbides, it is also possible to use combustion gas to perform direct heating, but this direct heating causes the unburned carbon contained in the hot air to contact the whitened white inorganic particles, resulting in a decrease in whiteness. Therefore, it is best to use Set up partition walls in such a way that the mud does not come into direct contact with hot air. That is, in decarburization-white

Description of the invention (15) The chemical treatment step is the same as the carbonization step. More preferably, the heating furnace is a double structure indirect heating furnace composed of a closed carbide decarburization-whitening chamber and a heating chamber. Although electric heating of the heating chamber is also feasible, it is best from the economic point of view to use kerosene or heavy oil for combustion. The hot air obtained by recovering the above-mentioned volatile gas from the mud and burning it can also be used. In addition, the combustion gas discharged from other existing incineration equipment such as an incinerator can also be used. The type of incineration equipment can be exemplified by the furnace type (such as the type of stoker furnace), the floating type, the material stirring type, and the hot air combustion type. 'In addition, a rotary kiln installed in each papermaking plant or an existing incinerator (cyclonic furnace or mobile incinerator) can be used as a part of the wastewater treatment device', and it is even better to use a Rotary kiln for decarbonization and albino treatment. In addition, during the carbonization treatment and decarburization-whitening treatment, once the object to be treated is cooled to a temperature of 400 ° C or lower, and then the subsequent treatment is performed, the carbide can be completely removed due to the carbonization treatment. Combustible gas from thermal decomposition of organic matter. In addition, when the carbide is brought into contact with water and / or water vapor for cooling during this period, the specific surface area of the carbide can be increased, and the reaction efficiency between the treated product and oxygen in the decarburization-whitening treatment step can be effectively increased. Decarbonization-whitening treatment. In the case of continuous carbonization and decarbonization-whitening, when a screw or a stirring blade is installed in the heat treatment chamber, sludge or carbide can be forcibly transferred by this. When forcibly squeezed in with a screw, stirring can be promoted to improve the efficiency of concrete treatment.

Description of the invention (18) Contact area. When the crushing chamber is provided with partitions and other components, these components also become part of the crushing area. For the case of wet grinders that crush media limbs, it is best to use abrasive balls covered with abrasion-resistant plastic or ceramic balls, and these balls also become one of the crushing areas. Plastics, such as urethane resin or nylon resin, can be exemplified by a thickness of about 1 mm to 1 〇_ The coating can be applied, and it can be appropriately selected according to the frequency of use or the pulverizing conditions. Press again, and you can also use a screening device (such as an open-type vibrating screen, multi-tubular vibration vibrating filter) before and after wet pulverization; (Pressure filter, etc.) to remove sintered materials that are difficult to crush. Furthermore, it is preferable that the dispersing machine be coated with rubber, wear-resistant plastic, etc. in the same manner as the wet red knife crusher. In the case of wet pulverization, under the purpose of uniform powder dispersion, a dispersant is added to perform slurrying. When a dispersant is added, it can prevent the viscosity from increasing, even when the slurry is highly concentrated. It is also the same when changing, in addition, it can prevent the viscosity increase caused by wet pulverization, and improve the pulverization efficiency or use =. At this time, in order to make the dispersant of polyacrylic acid containing sulfonic acid group have better than other dispersants The salt resistance and heat resistance are its advantages. It is best to add a polyacrylic acid containing an acid group (its molecular weight including the sulfonic acid group is 1 0 0 0 to 1 0 0 0 0) 0 05% to as a dispersant. When the added amount exceeds 3%, even if the added amount is increased, its dispersibility will not be changed. If the added amount is less than 0.05%, it will show poor dispersibility, and there is no way to perform it with good efficiency. Wet pulverization in step. The one shown in step 55 is white inorganic particles whose particle size is adjusted after pulverization treatment (due to this treatment), which may be reused as a pigment or filler suitable for papermaking.

It will be borrowed around a small kiln made of quartz that will rotate at a speed of ^ clock? The electric heating wire indirectly heats it, and blocks the sample input port of the kiln to prevent air from flowing in. The water vapor and carbonized gas are discharged from the open port of the other side. Regarding the carbonization temperature, the temperature of the atmosphere in the kiln reaches 4 in the first 30 minutes. 0 0. (The heating is performed at a rate of 3. After the mud is dried, the above-mentioned rotary kiln is used to perform thermal decomposition and carbonization. The heating is performed at a speed of 60 π in 30 minutes.

Description of the invention (30) It is concluded that the specific surface area of carbides is increased due to the spraying treatment of water on the carbides, resulting in carbides Effectively in contact with oxygen, it is decarburized and whitened. That is, the spray effect of water was confirmed. In the X-ray diffraction (picture) of the sample obtained in Example 4, the peak of calcium carbonate is clearly displayed, and the whiteness of the recovered sample is 85%, which is equivalent to that in Example 2, so it is suitable for use as Papermaking raw materials. In the whitening treatment step, a method of performing two-stage sintering at a temperature of 7000t after full decarburization at a temperature below 600 ° C and an adjustment of air flow can be used to prevent stone reflection.

Although the sludge was heat-treated at a temperature of 800 ° C, which is higher than that of Example 1, the obtained whiteness was equal to that of Example 1. The decarburization-whitening efficiency is lowered: The reason can be inferred that the white inorganic particles contained in the sludge were caused to melt and sinter on papermaking due to the sharp thermal treatment of the sludge without the carbonization step. σ In the X-ray diffraction (picture) of the sample obtained in Comparative Example 2, there were no spikes of kaolin and calcium carbonate. The whiteness of the recovered sample was 74%. Due to the rapid heat treatment in the decarburization-whitening treatment, the melting and sintering of the white non-particles contained in the sludge occurred, resulting in a reduction in the whiteness improvement rate. In the x-ray diffraction (picture) of the sample obtained in Comparative Example 3, there were no peaks of high and calcium carbonate. The whiteness of the incineration ash is 54%, which is very low, which is for the papermaking raw materials. ^
