Abstract

In a method of recycling iron and steel industry waste (1-1, 1-2) by processing the waste (1-1, 1-2) as an object substance by the use of a rotary kiln (7), the object substance is changed into a valuable material while the object substance travels within the rotary kiln (7) from an upstream side to a downstream side. The object substance is heated on the upstream side of the rotary kiln (7) within a reducing atmosphere to be reduced and molten into a reduced and molten product. The reduced and molten product is quickly sent to the downstream side without being adhered to an internal wall of the rotary kiln (7). The valuable material is extracted from the reduced and molten product which may be directly discharged out of the rotary kiln or which may be discharged after the reduced and molten product is once kept in a basin formed in the vicinity of the downstream side of the rotary kiln (7).

Description of Invention (>) Plutonium and lead, the industry has adopted a variety of well-known methods. Two second methods commonly used in web manufacturing processes. Especially in the first method, the zinc oxide contained in the waste material is volatilized and gradually destroyed by using coke as a priming agent in a rotary kiln. Zinc oxide is then removed from the waste. Furthermore, the oxidative interception of kanbara turned into sponge sponge with low content and returned to the oven or sintered tart. In the second method, the components of the catfish contained in the waste are distinguished from each other by a wet dust separation method, so that the waste is divided into a first part containing a high zinc concentration and a first part containing a low zinc concentration. Two parts. The first part was used in the non-starved gold plaque industry as the original sampan and the second part was fed back to the high slab or sintering machine in the iron making method. After that, the second part was subjected to the net loading procedure. As mentioned earlier, the lettuce oven and sintering machine are devices in the ironmaking process. In other words, the recovered material is used in the lock-making process before the bait-making process. Usually, the first method requires pre-treatment of a predetermined degree of sheet-like rejects before being fed into the rotary kiln. In addition, the recovered zinc-removed material cannot be returned to the manufacturing process, but it can be used as a raw material for the manufacturing process. This is due to the low purity of the valuable plutonium contained in the recycled material. Therefore, the first method is unfavorable because of the operating cost of recycling materials. On the other hand, zinc is disadvantageous because it does not shrink sufficiently and does not separate. In either of these methods, it is not possible to recover valuable materials at low operating costs. More specifically, the first method has another disadvantage. It will be explained. The first method should be M gas and solid reaction, so that the olive ore is directly Kangan-4-(Please read the precautions on the back before filling this page) This acre size is common to China National Standards (CNS) Α4.

The SIK completely burns the unburned substances in the exhaust gas. In addition, the high temperature pyrolysis of the second combustion chamber M will convert harmful substances such as Dioxitie into harmless gases and then discharge them outside the system. The exhaust gas is heated to a high temperature and the heat of combustion in the second combustion chamber is collected in a pot ® as the next stage steam. Therefore, the entire program consumes less heat. The gold smelt melt and slag were eroded into a water tank located below the discharge end of the rotary kiln. After cooling in the water tank, the metal melt and slag are discharged out of the system to be recovered. The cooling water tank 10 is supplied with the flail K circulating water so that the metal melt and the slag are stirred and sufficiently cooled. If necessary, the metal solution and slag can be separated at a later stage by magnetic separation.

The proportion of invention description (*) is greater than that of dissolved residue. As a result, the metal solution sinks under the slag and is completely covered by the slag. So the slag becomes the space between the dissolution chamber of the gold plaque and the oxidation environment. The solution and slag of gold ore separated by K specific gravity are discharged to a cooling water tower 10 at the discharge end of the rotary kiln 7. If the subject matter contains hexavalent chromium, it is a harmful substance. After passing through the primordial and melting steps as described above, hexavalent chromium is converted into gold tin chromium or trivalent chromium and is harmless.

Subsequently, the exhaust gas is discharged from the rotary kiln 7 and will be processed later. The gas discharged from the rotary kiln 7 is introduced into the second combustion chamber 11 coupled to the discharge end of the rotary kiln 7. The second combustion chamber can completely burn unburned substances contained in the exhaust gas. In addition, harmful substances contained in the exhaust gas are thermally decomposed into non-hazardous substances. The exhaust gas is then passed through a heat recovery unit or heat exchanger 13, which is like a boiler, and then goes to the settler 14 to be discharged to the atmosphere. According to the nature and nature of the plutonium, the quality and quantity of the material to be recovered, and the cost of the original agent and fuel, the atmosphere in the rotary kiln 7 can be based on two conditions.

Description of Invention (G) Choice, which is (A)-a kind of primordial or very weak oxidizing atmosphere and (B ) —A kind of weak oxidation environment. (A) Kanyuan or extremely weak oxidation environment. It is assumed that the internal space of the rotary kiln 7 is maintained in Kanyuan environment or a very weak oxidation environment with low oxygen content. In this environment The Jinting solution is very oxidized. In order to provide such an environment, the K activator must be fully charged in the rotary kiln 7. In particular, the original amount of the raw material added to the target can be calculated as two equivalents of the required reducing agent. Times. Or, the carbon oxide concentration at the exit end of the rotary kiln 7 is maintained at 5X or higher, which occurs in the gas space and is the result of the original. In the above situation, the rotary kiln is preferably provided with a pot, which is formed at It is reserved for the discharge section of gold tin melt and slag. In the process, the metal melt and slag are introduced into contact with each other. In the contact, the various elements combined in the slag are transferred to the gold smelt due to the slag in the gold plaque and because the metal slag and the molten slag The distribution reaction is distributed between the slag and the metal melt. Therefore, the metal melt and the slag in the composition are discharged out of the rotary kiln to become a recycled material. The metal melt is made into an iron alloy. As a result It can improve the recovery rate of the samarium alloy and eliminate the amount of gold samarium remaining in the slag. Therefore, the slag containing a small amount of gold plaque can be applied to various occasions. According to the present invention, a rotary kiln with a pot can be formed into a variety of types Structure. Several types of structures will be described later with reference to the drawings. Referring to Figure 2, a simplest rotary kiln 21 having a length of, for example, between 10 and 15 meters. From the population end (left-hand side in the figure) to The exit end (right hand side in the figure). The rotary kiln 21 has a basin 211 and an outlet weir 212 on its inner surface. The basin 211 is scheduled to be calculated from the discharge end of the rotary kiln -15- (Please read the back (Please fill in this page again for attention) National Standards (CNS. 2 丨 0X 297) 45 55 1 6 A7 __B7_ V. The scope of the invention description (K) extends to the population end. For example, for a rotary kiln of the above length, the predetermined distance is difficult to be 1 meter. Between 2 meters. In particular, the pot 2U is formed by widening the inner diameter at the above predetermined distance. The molten product, including metal melt and slag, is held in the pot 211 for a predetermined time Μ The accelerating gold smelt melt is allowed to separate from the slag. In order to widen the inner diameter of the rotary kiln 21, an inner flame layer (not shown) is formed on the inner surface of the rotary kiln 21, in a predetermined distance corresponding to the above-mentioned pot 211. Reduce its thickness so that the outer diameter of the outer die of the rotary kiln 21 is not changed. Or, the outer diameter of the outer shell is widened without changing the thickness of the inner refractory layer. Referring to FIGS. 3A and 3B, the rotary kiln 22 has a basin 221. At least a pair of discharge channels 223 are formed in the rotary kiln 22, which are radially opposed to each other, and at least a pair of discharge plugs 22 are arranged in the discharge channel. 223. The discharge channel 223 is used to discharge the molten product from the rotary kiln 22 when the rotary kiln 22 is stopped. The discharge plug 224 is used to open the discharge channel 223 by removing the plug and placing the discharge channel respectively. Referring to FIGS. 4A and 4B, a rotary kiln 23 has a pot 231 and a raised block 233 formed in the pot 231.

Referring to Fig. 5, a rotary kiln 24 includes a cylindrical outer shell and an inner refractory layer formed on the inner surface of the outer slug. The outer dice and the inner refractory layer are not shown in circles. The inner refractory layer defines a basin 241 and has an inner diameter D1 and a length L1, the middle section 244 has an inner diameter D2 (D2 < D1) and a length L2, and a gas-solid reaction section 243 has a length L3, and an inner diameter D3, Equal to basin 241-1 6-This paper size applies the National Standard (CNS) M specification (210X297 mm) 4 5 5 5] Printed by the Consumer Cooperatives of the Zhongjia Standard Bureau of the Ministry of Economic Affairs A7 _B7_ V. Invention Explanation (/) Path D1. The gas wax-solid reaction section 243 is separated from the basin 241 by the middle section 244. The basin 241, the middle section 244, and the gas-solid response section 243 can be changed according to the required shape, and the thickness of the inner fire layer can be changed without changing the outer diameter. In addition, the gas-solid reaction section 243 can be thickened, and this structure reduces the influence of the oxidizing environment on the bed. The bed can then remain exposed to the original environment. In addition, the existence of the intermediate section 244, the molten product is kept in the basin 241 to prevent its expansion back to the gas-solid reaction section 2 43, and does not interfere with the object from the upstream side to the downstream side. In addition, it is easy to replace the internal fire layer without changing the outer diameter of the die to change the area of the gas-solid reaction section 243 and the basin 241. Referring to FIG. 6A and FIG. 6B, a rotary kiln 25 has a pot 251, a discharge weir 252, and an inner weir 253, Μ. With this structure, the gold smelt melt layer M is slag layer S M in the pot 251. Covered by thickness. This is to prevent the surface of the gold-alloy melt layer M from being exposed to an oxidizing environment. Referring to FIGS. 7A and 7B, a rotary kiln 26 has a basin 261 and a plurality of grooves 263 formed in the basin 261 so as to extend in the longitudinal direction of the rotary kiln 26. The gold rhenium melt layer M is deposited in the trenches 263 and discharged through the trenches 263. On the other hand, the slag layer S is discharged over the entire edge of the rotary kiln 26. The advantage of this structure is that the slag layer S and the gold melt layer M can be discharged from different locations separately, and the metal body layer in the basin 261 can be prevented from being completely discharged at one time, even when a large most molten product is produced. . (B) Weakly oxidizing environment The space in the rotary kiln can maintain the oxidizing environment, so that when the metal melt is held in the rotary kiln for a long time, oxidation occurs. To facilitate this -17-

Description of the invention (4) For the environment, the amount of kangaroo clams added to the subject is not greater than the calculated equivalent of kanyuan It is twice as much as that produced in the oxygen space. Its concentration is about 5X at the discharge end. In this way, there is no need to form a basin area in the rotary kiln. In other words, there is no need to set a weir to form a basin. This means that the designed rotary kiln allows the gold plaque melt to be immediately discharged without staying in the rotary kiln. The metal melt is made into an iron alloy. Compared with the structure of the pot, the recovery rate of the iron alloy is low and the gold content in the slag is low. Higher. However, the advantage of this non-pot structure is that the amount of rhenium agent added to the target can be reduced, especially as small as 1.2 to 1.5 times the required amount of rhenium. In addition, the carbon monoxide produced by the reduction of Ranke is reduced. It can be saved by burning in the rotary kiln. A special case, and the device used to implement this method. In this case, the general dust formed by the K-net iron factory is for testing. The dust used is formed by the process of manufacturing stainless steel. As the target or material The dust composition is shown in Table 1.

Description of the invention () Preliminary processing of the materials, the above dust is mixed with the powder phase and coking kanji agent in a wet process. After dehydration, the warm compound is fed into Test device. The dust / coke dust ratio is 100/43 by weight. The ratio of coke dust is twice the equivalent of the calculated equivalent of the original.… The device used in this test is a batch rotation as shown in Figure 8. Kiln test furnace. Attention must be paid Although this test furnace is not all the same as the rotary kiln structure of a commercial device, the longitudinal conveying position of the subject in the rotary kiln corresponds to the operating time of the test entropy. Referring to Figure 8, Rotary® has a chamber 54, a furnace 55, —drive tooth key 56, —roller wheel 57, —slip ring 58, —discharge plug 59. —first viewport 60, surveillance camera 61, and a second viewport 62. The inner diameter D of the chamber is 1300 strokes and the length L is 500 mm. In the test, the moisture content of 140 kg of dehydrated cake was 22¾, which was added to the original rotary kiln of 5001C and heated with propane gas as fuel. The rotary kiln K.4rp «i (revolutions per minute) rotates. See Figure 9 for the temperature rise rate of the bed. After the dust (dehydrated cake) has been added, samples of gold smelt melt and slag are taken every 90 minutes and proceeded until a molten product is produced. The analysis of the samples is based on the degree of zinc removal, the degree of resistance, and the degree of metallization. In particular, the degree of zinc removal (the original zinc content has a zinc content) / (the original zinc content) is expressed. The original degree K (original aerobic content) " original aerobic content " The degree of metallization M (existing gold iron) / (existing total iron content) is expressed. Then, after the molten product is generated, the metal melt and the slag are successively deposited. From the analysis of the composition of Jinli melt and slag, the gold ring melt and melt were obtained. -19- This paper's dimensions are applicable to Chinese National Standard (CNS) Λ4 grid (210 × 297 mm) [Order II {Please read the note on the back first Please fill in this page again for matters) 455516 A7 B7 V. Description of the invention (,) Distribution of each metal element between slags. This test was performed five times under the conditions of Baitong to get the test result of Wujie. In the five sister test results, few fluctuations were observed by Fei. Therefore, one set of each test result of M is shown separately on lap 10. Fig. 10 shows the degree of originality, the degree of golden spread, and the degree of zinc removal at different points in time before the melt is formed. Refer to Figure 10, it can be seen that after about 90 minutes since the dust was fed into the rotary kiln, the values of gangrene have reached 90 JK or M each. After about 100 minutes of feeding dust, a metal melt was produced. At this time, the temperature of the bed is between about 12 50 and 1300 C, and the slag is also melted.
