Description

Technical Field

[0001] This invention belongs to the field of recycling device technology, specifically, it relates to a slag recycling device. Background Technology

[0002] Coal is my country's main energy source and an important chemical raw material. Coal gangue produced from coal mining, fly ash from coal-fired power generation, bottom ash, desulfurization gypsum, and gasification slag from coal chemical industry form common coal-based solid waste, namely slag.

[0003] To avoid wasting resources, coal-based solid waste is often treated by incineration or chemical reaction to extract useful metal resources. The remaining reactants are ground into granules and used as building materials for road paving, thereby improving resource utilization and reducing the pollution of coal-based solid waste to the surrounding environment.

[0004] Existing methods for preparing backfill materials from coal-based solid waste CO2 include, for example, patent application number CN202210280209.2, entitled "A Method for Preparing Mine Cemented Backfill Materials from Mineralized CO2 of Industrial / Mining Solid Waste," which describes a method for preparing mine cemented backfill materials from mineralized CO2 of industrial / mining solid waste. The method includes the following steps: grinding industrial / mining solid waste and uniformly mixing it with ammonium nitrate; placing the mixture in a reactor for molten salt activation, collecting the ammonia gas generated during activation, and converting Ca, Mg, and Al in the activated raw materials into corresponding metal nitrates; leaching the activated mixture with water, and filtering to obtain a water-leached residue mainly composed of SiO2 and rich in Ca. 2+ Mg 2+ Al 3+ The aqueous extract; the collected ammonia, the obtained aqueous extract, and the pre-prepared CO2 are introduced into a reaction vessel to undergo a carbonation reaction, and filtered to obtain a filtrate containing ammonium nitrate and mineralized slag with CaCO3, MgCO3, and Al2(CO3)3 as the main phases; the mineralized slag is mixed with cement and gypsum to make a cementitious material; the cementitious material is mixed with water and tailings to make a cemented backfill material.

[0005] The invention achieves the rational utilization of coal-based solid waste. However, in its use, the aluminum, which has certain value, is not extracted. Instead, the slag produced by the reaction of coal-based solid waste is directly crushed and mixed for road paving, which results in a waste of resources and has certain shortcomings. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a recycling device that can overcome or at least partially solve the above problems.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: it includes a reaction tower, a reaction device, a generating device, and further includes:

[0008] A first connecting pipe is connected to the reaction tower, and the other end of the first connecting pipe is connected to the reaction device. The first connecting pipe is inclined and has a rotary valve inside.

[0009] A second connecting pipe is connected to the reaction device, and the other end of the second connecting pipe is connected to the generating device. The second connecting pipe is inclined and has a rotary valve inside.

[0010] A top inclined plate is inclinedly installed inside the reaction device, with the lower end of the top inclined plate located above the connecting pipe one;

[0011] A side inclined plate is inclinedly disposed inside the reaction device. The high end of the side inclined plate is located below the high end of the top inclined plate, and the side inclined plate and the top inclined plate do not contact each other. The high end of the second connecting pipe is located at the low end of the side inclined plate.

[0012] The reaction device is filled with water, the water level is higher than the side inclined plate, and the water does not completely fill the reaction device.

[0013] In operation, a raw liquid rich in Ca, Mg, and Al is poured into the reaction tower. The raw liquid undergoes a mineralization reaction in the reaction tower to generate mineralized slag with CaCO3, MgCO3, and Al2(CO3)3 as the main phases. The mineralized slag then enters the reaction device through connecting pipe one. The Al2(CO3)3 in the mineralized slag reacts with water to generate flocculent Al(OH)3 and CO2. The remaining mineralized slag does not react with water. The flocculent material itself is rich in fine fibers, which can adhere to air bubbles. Since the flocculent material is relatively light, it carries the air bubbles of CO2 upwards to the side inclined plate. The CO2 comes into contact with the gas, breaks up, and dissolves in the gas. The flocculent material sinks and finally enters the generating device through connecting pipe two. The generating device heats the flocculent material to convert it into water vapor and Al2O3. The water vapor is discharged to the outside, and the Al2O3 is heated again with carbon powder to generate CO2 and Al.

[0014] To facilitate the recovery of carbon dioxide generated by subsequent devices and the mineralization reaction in the reaction tower, the reaction device is further equipped with a gas suction device, which includes a high-pressure gas pump and a connecting gas pipe. The high-pressure gas pump is connected to the reaction device, and the connecting gas pipe is connected to the high-pressure gas pump. The inlet end of the connecting gas pipe is connected to the reaction device and the generating device, respectively, and the outlet end of the connecting gas pipe is connected to the reaction tower.

[0015] To facilitate the separate extraction of carbon dioxide generated in the reaction device and the generating device, a control valve is further connected to the connecting gas pipe.

[0016] To facilitate the discharge of remaining calcium carbonate and magnesium carbonate and the addition of water to the reaction device, the reaction device is further equipped with a water inlet pipe and a feed pipe. A waste residue tank is located below the reaction device and is connected to the feed pipe. A rotary valve is installed inside the feed pipe.

[0017] To further improve the reaction rate, a drive motor is fixedly connected to the generating device, the output end of the drive motor passes through the generating device, and a rotating stirring shaft is fixedly connected to the output end of the drive motor.

[0018] To facilitate the reaction of aluminum hydroxide and aluminum oxide by heating, a heating tube is further fixedly connected inside the generating device. The heating tube is arranged in a spiral shape inside the generating device and is located away from the rotating stirring shaft.

[0019] To facilitate the entry and exit of the raw liquid, the reaction tower is further equipped with a feed pipe and a discharge pipe, both of which are connected to a rotary valve. The high end of the connecting pipe is connected to the reaction tower.

[0020] To facilitate the collection of aluminum hydroxide, the reaction device is further provided with two sets of collection slopes above the side inclined plate, and the liquid inlet end of the second connecting pipe is located between the two sets of collection slopes.

[0021] To facilitate the discharge of generated aluminum and water vapor, the generating device is further equipped with a gas outlet pipe and a material discharge pipe, both of which are connected to a rotary valve.

[0022] To facilitate the discharge of remaining slag, the bottom of the waste slag tank is further connected to a pipeline, and a rotary valve is installed inside the pipeline.

[0023] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention can separate aluminum from other waste residues by taking advantage of the property that aluminum carbonate can react with water to produce carbon dioxide and aluminum hydroxide, and can recycle aluminum, which is convenient for subsequent aluminum processing and resource utilization. At the same time, the carbon dioxide produced can be rationally utilized, which is green and environmentally friendly and easy to use. Moreover, the remaining slag can also be used for road paving, which can comprehensively utilize the slag. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] Example 1: Refer to Figures 1-9A slag recycling device includes a reaction tower 1, a reaction device 2, and a generating device 3. It further includes: a first connecting pipe 501 connected to the reaction tower 1, with its other end connected to the reaction device 2, and the first connecting pipe 501 is inclined; a second connecting pipe 502 connected to the reaction device 2, with its other end connected to the generating device 3, and the second connecting pipe 502 is inclined; a top inclined plate 201. The top inclined plate 201 is inclined inside the reaction device 2, with its lower end above the connecting pipe 501. The side inclined plate 202 is also inclined inside the reaction device 2, with its upper end below the upper end of the top inclined plate 201, and the side inclined plate 202 and the top inclined plate 201 not in contact. The upper end of the connecting pipe 502 is located at the lower end of the side inclined plate 202. The reaction device 2 is filled with water, the water level is higher than the side inclined plate 202, but the water does not completely fill the reaction device 2; the water surface is level with the top of the reaction device 2. Sufficient gaps exist to prevent the air pump 401 from sucking up the flocculent material while also facilitating the breakage of carbon dioxide bubbles within the flocculent material. During operation, a raw solution rich in Ca, Mg, and Al is poured into reaction tower 1. The raw solution undergoes a mineralization reaction in reaction tower 1, generating a mineralized slag with CaCO3, MgCO3, and Al2(CO3)3 as its main phases. The mineralized slag then enters reaction device 2 through connecting pipe 501. The Al2(CO3)3 in the mineralized slag reacts with water to generate Al(OH) flocculent material. 3 reacts with CO2, while the remaining mineralized slag does not react with water. The flocculent material itself is rich in fine fibers, which can adhere to air bubbles. Since the flocculent material is relatively light, it will carry the bubble-like CO2 upwards to the side inclined plate 202. The CO2 comes into contact with the gas, breaks up, and dissolves in the gas. The flocculent material will sink and finally enter the generating device 3 through the connecting pipe 2 502. The generating device 3 heats the flocculent material into water vapor and Al2O3. The water vapor is discharged to the outside, and the Al2O3 is heated again with carbon powder to generate CO2 and Al.

[0037] The reaction apparatus is equipped with a suction device 4, which includes a high-pressure air pump 401 and a connecting air pipe 402. The high-pressure air pump 401 is connected to the reaction apparatus 2, and the connecting air pipe 402 is connected to the high-pressure air pump 401. The air inlet of the connecting air pipe 402 is connected to the reaction apparatus 2 and the generating apparatus 3, respectively, and the air outlet of the connecting air pipe 402 is connected to the reaction tower 1. A control valve 403 is connected inside the connecting air pipe 402. An air outlet pipe and a discharge pipe are fixedly connected to the generating apparatus 3, and rotary valves are connected inside both the air outlet pipe and the discharge pipe. An inlet pipe 101 and an outlet pipe 102 are connected to the reaction tower 1. A valve is installed inside the outlet pipe 102 to prevent the discharge of particles and allow only the discharge of liquid. Rotary valves are connected to both the inlet pipe 101 and the outlet pipe 102. The high end of the connecting pipe 501 is connected to the reaction tower 1. A heating pipe 303 is fixedly connected inside the generating apparatus 3, and the heating pipe 303 is arranged in a spiral shape inside the generating apparatus 3.

[0038] When using this device, it needs to be used in conjunction with the existing crushing and grinding mill and reactor. The coal-based solid waste is crushed and ground by the crushing and grinding mill to form particles with a particle size of 60 to 200 micrometers. Similarly, the mineralized slag generated later can also be crushed by grinding to promote the reaction effect. Then, the ground particles are introduced into the reactor, where ammonium nitrate is added in a 1:2 ratio and mixed evenly. Molten salt activation is carried out in the reactor at an activation temperature of 20 to 90 degrees Celsius. At this time, the coal-based solid waste particles will react with ammonium nitrate to generate ammonia gas. The ammonia gas is collected and injected into reaction tower 1. At the same time, the Ca, Mg, and Al metals in the coal-based solid waste particles will be converted into corresponding metal nitrates. The metal nitrate mixture is then subjected to water leaching treatment to obtain a water leaching solution rich in Ca, Mg, and Al, i.e., the original solution.

[0039] The raw liquid can then be added to the reaction tower 1 in this device through the feed pipe 101. Carbon dioxide is injected into the reaction tower 1, which now contains ammonia, carbon dioxide, and the raw liquid. The reaction tower 1 is then sealed, and the temperature is raised to between 20-90 degrees Celsius and the pressure to 0.15-2 kPa. The mineralization time is 60-120 minutes. During this time, the raw liquid undergoes a mineralization reaction, in which Ca, Mg, and Al react to form particulate precipitates, mainly composed of calcium carbonate, magnesium carbonate, and aluminum carbonate particles, which settle to the bottom. After the mineralization is complete, the discharge pipe 102 is opened, and the filter screen filters out the particles generated by the mineralization reaction. The remaining liquid is discharged through the discharge pipe 102. This liquid can be recovered and purified into high-purity ammonium nitrate liquid, which can then be reused in the reactor.

[0040] Then, the connecting pipe 501 is opened, and the remaining particles will enter the reaction device 2 through the connecting pipe 501. Since the reaction device 2 is filled with water at this time, and calcium carbonate does not react with water, magnesium carbonate is slightly soluble in water, while aluminum carbonate reacts with water to produce a violent reaction, generating carbon dioxide and aluminum hydroxide. The specific equation is Al2(CO3)3 + 3H2O = 2Al(OH)3 + 3CO2, where aluminum hydroxide is flocculent. Due to its flocculent nature, a large number of carbon dioxide bubbles will adhere to the surface of the flocculent. At this time, the carbon dioxide bubbles will carry a large amount of flocculent aluminum hydroxide to the water surface until they contact the top inclined plate 201. The material will move along the top inclined plate 201. At this time, some of the carbon dioxide bubbles in contact with the top inclined plate 201 may burst, but the remaining carbon dioxide bubbles will still drive the flocculent material to move until it passes through the gap between the top inclined plate 201 and the side inclined plate 202 and comes into contact with the space inside the reaction device 2. The carbon dioxide bubbles in the flocculent material will gradually leave the flocculent material after contacting the outside air. At this time, the flocculent aluminum hydroxide that floats due to the bubbles will fall down and come to the side inclined plate 202. At this time, the collection of aluminum hydroxide is completed. At this time, the generated carbon dioxide can be drawn into the reaction tower 1 by activating the air suction device 4, which facilitates the subsequent mineralization reaction of the original solution.

[0041] Then, connect pipe 2 502 can be opened to allow water containing aluminum hydroxide to enter the generating device 3. After that, connect pipe 2 502 is closed, and heating pipe 303 is started to heat the water containing aluminum hydroxide. The water will turn into water vapor and be discharged through the vent pipe until only aluminum hydroxide remains. At the same time, the aluminum hydroxide will be heated to generate water and aluminum oxide until only aluminum oxide remains. At this point, a suitable catalyst carbon powder is added through the vent pipe and the vent pipe is closed. Heating pipe 303 is started again to allow the carbon powder to react with aluminum oxide: 2Al2O3 + 3C + → 4Al + 3CO2, generating carbon dioxide and aluminum. At this point, the carbon dioxide generated can be drawn into the reaction tower 1 by starting the suction device 4 to facilitate the subsequent mineralization reaction of the raw liquid. At this point, the extraction of aluminum is completed, and the discharge pipe can be opened to discharge the aluminum and carbon powder. The aluminum can then be melted, purified, and cast into shape for use in building materials.

[0042] This device also has another implementation method, such as... Figure 2As shown, another set of gas pipes is installed on the connecting gas pipe 402. The gas outlet of the gas pipe is connected to the bottom of the reaction device 2. At this time, the carbon dioxide generated by the reaction device 2 and the generating device 3 can enter the reaction device 2 and blow the mineralized particles accumulated at the bottom of the reaction device 2, so that the aluminum carbonate that has not been in contact with water comes into contact with water, generating carbon dioxide and aluminum hydroxide. The carbon dioxide rises with the airflow until it reaches the side inclined plate 202, which facilitates the collection of aluminum hydroxide. Some flocculent matter that cannot rise due to insufficient carbon dioxide bubbles will also move upward with the airflow and eventually enter the side inclined plate 202. The carbon dioxide airflow should not be too large, otherwise it will cause a large amount of other mineralized particles to come to the side inclined plate 202 with the airflow, affecting the quality of aluminum in the future.

[0043] This device can also be configured such that the initial state of reaction device 2 is waterless, and water is added after the mineralized particles are poured in.

[0044] In this device, aluminum carbonate may hydrolyze with the residual liquid in reaction tower 1. At this time, a protective film will form on the surface of aluminum carbonate, which will block the subsequent hydrolysis reaction. Therefore, the particles discharged from reaction tower 1 need to be dried first, then ground into fine particles, and then put back into reaction device 2. This can effectively avoid the situation where aluminum carbonate does not react with water in reaction device 2 and produces flocculent matter.

[0045] Example 2: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 A slag recycling device is basically the same as in Example 1, but further: a water inlet pipe and a feed pipe 203 are connected to the reaction device 2, a waste slag tank 204 is provided below the reaction device 2, the waste slag tank 204 is connected to the feed pipe 203, a rotary valve is provided in the feed pipe 203, and a pipeline is connected to the bottom of the waste slag tank 204, and a rotary valve is provided in the pipeline.

[0046] By setting up the water inlet pipe and the feed pipe 203, the accumulated mineralized particles can be discharged, avoiding the large accumulation of particles from affecting the subsequent aluminum carbonate reaction. At this time, the water level drops, and the water inlet pipe should be located on the side inclined plate 202. At this time, the connecting pipe 2 502 can be opened, and the remaining aluminum hydroxide on the side inclined plate 202 can be carried into the generating device 3 by the impact of the water flow. Then, the connecting pipe 2 502 is closed to raise the water level in the reaction device 2 for subsequent use.

[0047] Next, open the rotary valve in the pipeline separately to discharge the slag in waste slag tank 204. At this time, the slag can be dried first. Then, mix the slag, cement, and gypsum in a mass ratio of 75%, 10%, and 15% and inject them into a grinding machine or crushing machine to crush and mix the slag. At this time, a new type of adhesive material for road paving can be obtained. The new adhesive material can also be made into some industrial bricks to further expand its application range.

[0048] Example 3: Reference Figure 8 , Figure 9 A slag recycling device is basically the same as that in Embodiment 1, but further: a drive motor 301 is fixedly connected to the generating device 3, the output end of the drive motor 301 passes through the generating device 3, a rotating stirring shaft 302 is fixedly connected to the output end of the drive motor 301, and the heating tube 303 is far away from the rotating stirring shaft 302.

[0049] By rotating the stirring shaft 302, the reaction efficiency of carbon powder and alumina can be improved through stirring.

[0050] Example 4: Reference Figure 5 A slag recycling device is basically the same as that in Example 1, but further: the reaction device 2 has two sets of collection slopes above the side inclined plate 202, and the liquid inlet end of the connecting pipe 2 502 is located between the two sets of collection slopes.

[0051] The collection slope facilitates the deposition of aluminum hydroxide at the connecting pipe 2 502, and also facilitates the recovery of residual aluminum hydroxide when replenishing water in the subsequent water inlet pipe.

[0052] This invention utilizes the property that aluminum carbonate can react with water to produce carbon dioxide and aluminum hydroxide, which allows for the separation of aluminum from other waste residues, enabling the recycling of aluminum and facilitating subsequent aluminum processing and utilization. At the same time, the generated carbon dioxide can be rationally utilized, making it green, environmentally friendly, and easy to use. Furthermore, the remaining slag can be used for road paving, enabling comprehensive utilization of slag.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention.
