Description

Technical Field

[0001] This application relates to the technical field of industrial solid waste resource utilization, and in particular to a complete set of equipment for the co-processing and resource utilization of gasification fine slag and deslurry slag. Background Technology

[0002] Gasification slag and desizing slag are two typical industrial solid wastes. Gasification slag is the fine particulate matter collected by the dust removal system after coal is gasified at high temperature in a gasifier. Desizing slag is a solid or semi-solid waste formed after pretreatment of high-concentration organic wastewater generated in the desizing process in the textile industry. Their traditional disposal methods both involve resource waste and environmental pollution risks.

[0003] Because gasification slag and textile desizing slag have different properties, manufacturers usually process and recycle them separately. Manufacturers need to develop different treatment plans to achieve the reuse of coal gasification slag and textile desizing slag. This results in low integration between the treatment equipment for the two types of solid wastes and insufficient overall system coordination. At the same time, there is a lack of material circulation design throughout the entire process, which leads to a large consumption of fresh raw materials during the production process. This restricts the industrial application and economic benefits of the dual solid waste co-resource utilization technology. Utility Model Content

[0004] In order to achieve the co-processing of coal gasification slag and textile desizing slag, this application provides a complete set of equipment for the co-processing and resource utilization of gasification slag and desizing slag.

[0005] This application provides a complete set of equipment for the co-processing and resource utilization of gasification fine slag and deslurry slag, which adopts the following technical solution: A complete set of equipment for the co-processing and resource utilization of gasification fine slag and deslurry slag includes a deslurry slag treatment module and a gasification fine slag treatment module. The deslurry slag treatment module is used to prepare a carbon-based adsorbent after processing the deslurry slag, and the gasification fine slag treatment module is used to prepare a coagulant after processing the gasification fine slag. The gasification fine slag treatment module includes an acid leaching reaction device and a first solid-liquid separation device, in which the first solid-liquid separation device performs solid-liquid separation on the acid leaching liquid after processing by the acid leaching reaction device. The deslurry slag treatment module includes an ultrafiltration device and an adhesive preparation device. The adhesive preparation device is used to prepare adhesive from PVA concentrate separated by an ultrafiltration device. It also includes a conversion module for preparing crude sodium silicate solution from the acid residue after solid-liquid separation. The conversion module includes an alkali dissolution reaction device and a second solid-liquid separation device. The alkali dissolution reaction device is provided with an alkali inlet for supplying external alkali solution. The second solid-liquid separation device is provided with a crude sodium silicate solution pipeline connected to the adhesive preparation device. The second solid-liquid separation device is used to transport the crude sodium silicate solution after solid-liquid separation to the adhesive preparation device.

[0006] By adopting the above technical solution, the acid slag separated by the first solid-liquid separation device is prepared into crude sodium silicate solution through a conversion module. This allows the external alkaline solution and acid slag to be fully mixed and reacted in the alkaline dissolution reaction device. Then, the alkaline solution and alkaline slag are separated by the second solid-liquid separation device. The crude sodium silicate solution after solid-liquid separation is then transported to the adhesive preparation device through the crude sodium silicate solution pipeline, so as to realize the self-produced adhesive as a raw material for the subsequent preparation of carbon-based adsorbents. Through structural integration and process optimization, both gasification fine slag and desizing slag are converted into raw materials or products within the system, realizing the synergistic treatment of the two solid wastes, thereby achieving internal circulation and near-zero emissions in the dual solid waste treatment process. This also improves the equipment's processing efficiency and control precision, providing a feasible path for the resource utilization of dual solid wastes.

[0007] Optionally, the first solid-liquid separation device has an acid slag outlet, the alkali dissolution reaction device has an alkali-soluble solid inlet, and a second conveying mechanism is provided between the first solid-liquid separation device and the alkali dissolution reaction device. The second conveying mechanism is used to convey the acid slag from the acid slag outlet to the alkali-soluble solid inlet.

[0008] By adopting the above technical solution, a second conveying mechanism is provided between the first solid-liquid separation device and the alkali dissolution reaction device, so that the second conveying mechanism can transport the acid slag from the acid slag outlet to the alkali dissolution solid feed inlet, thereby realizing the utilization of the acid slag generated during the gasification fine slag treatment process. The acid slag can enter the conversion module to provide raw materials for the preparation of sodium silicate crude solution, reducing the steps required for manufacturers to process acid slag and bringing higher economic benefits.

[0009] Optionally, the desizing slag treatment module further includes a granulation device and a curing device. The granulation device is used to mix the adhesive prepared by the desizing slag treatment module and the alkali slag separated by the second solid-liquid separation device in proportion and then granulate them. The curing device is used to cure the carbon-based adsorbent.

[0010] By adopting the above technical solution, the alkaline slag generated by the conversion module and the self-produced adhesive are mixed, granulated and solidified through the granulation device and the solidification device, and finally carbon-based adsorbent is produced. This allows the alkaline slag obtained after the gasification fine slag reaction and the self-produced adhesive to be fully utilized. This not only realizes the synergistic treatment of gasification fine slag and deslurry slag, but also opens up a continuous production process from raw materials to products. Thus, an internal cycle is built in the dual solid waste treatment system, realizing the full resource utilization of waste.

[0011] Optionally, the second solid-liquid separation device is provided with an alkali residue outlet, the granulation device is provided with a solid material inlet, and a third conveying mechanism is provided between the second solid-liquid separation device and the granulation device.

[0012] By adopting the above technical solution, a third conveying mechanism is provided between the second solid-liquid separation device and the granulation device, which enables the third conveying mechanism to transport the alkali residue from the alkali residue outlet to the solid material inlet, so as to realize the treatment of the alkali residue. After the alkali residue reacts with the adhesive to form granules and solidify, a carbon-based adsorbent is generated, thereby achieving solid waste treatment more efficiently.

[0013] Optionally, the adhesive preparation device has an adhesive outlet, the adhesive outlet is provided with an adhesive pipeline, the granulation device has an adhesive inlet, and the two ends of the adhesive pipeline are respectively connected to the adhesive outlet and the adhesive inlet.

[0014] By adopting the above technical solution, the adhesive outlet and adhesive inlet are connected to the two ends of the adhesive pipeline respectively, so that the adhesive can enter the granulation device through the adhesive pipeline for granulation reaction, providing a raw material basis for the subsequent preparation of carbon-based adsorbents, and further realizing the full resource utilization of dual solid wastes.

[0015] Optionally, the first solid-liquid separation device is equipped with a circulation pipeline, which includes a density detection unit and an electromagnetic reversing valve. The density detection unit is used to detect the density of the acid leaching solution in the circulation pipeline in real time. The electromagnetic reversing valve is equipped with a finished coagulant delivery pipe, and the outlet of the finished coagulant delivery pipe is equipped with a finished coagulant storage tank for storing the coagulant. When the density detection unit detects that the density of the acid leaching solution is lower than a set value, the electromagnetic reversing valve guides the acid leaching solution to flow into the circulation pipeline. When the density detection unit detects that the density of the acid leaching solution is greater than or equal to the set value, the electromagnetic reversing valve guides the acid leaching solution to flow into the finished coagulant delivery pipe.

[0016] By adopting the above technical solution, a density detection unit and an electromagnetic reversing valve are installed on the circulation pipeline, making the circulation pipeline a dynamic sampling channel. The density detection unit can detect the density change of the acid leaching solution in the circulation pipeline in real time and continuously. The reversing valve can switch the pipeline according to the density value of the acid leaching solution detected by the density detection unit in real time, so that the acid leaching solution can flow into the finished coagulant delivery pipeline only when it reaches a certain set value. The acid leaching solution that does not reach the set value needs to return to the circulation pipeline to continue the reaction, reducing the occurrence of incomplete leaching of target components due to insufficient acid leaching solution density, thereby improving the product quality of the subsequent finished coagulant.

[0017] Optionally, the ultrafiltration device has a supernatant outlet, the supernatant outlet is provided with an ultrafiltration supernatant pipeline, the acid leaching reaction device has an acid leaching liquid inlet, and the two ends of the ultrafiltration supernatant pipeline are respectively connected to the supernatant outlet and the acid leaching liquid inlet.

[0018] By adopting the above technical solution, the supernatant outlet and the acid leaching liquid inlet are connected to the two ends of the ultrafiltration supernatant pipeline, respectively. This allows the supernatant after the desizing sludge is separated by the ultrafiltration device to enter the acid leaching reaction device through the supernatant pipeline, supplementing the raw materials for the acid leaching reaction of the gasified fine sludge. This enables both the supernatant and concentrated water of the desizing wastewater to be converted into raw materials or products within the system, further realizing the full resource utilization of both solid wastes.

[0019] Optionally, both the acid leaching reaction device and the alkali dissolution reaction device are equipped with heating jackets, which are used to heat the acid leaching reaction device and the alkali dissolution reaction device to the reaction temperature.

[0020] By adopting the above technical solution, both the acid leaching reaction device and the alkali dissolution reaction device are equipped with heating jackets. The heating jackets can heat the acid leaching reaction device and the alkali dissolution reaction device to a specific reaction temperature and accelerate the reaction rate of the solution, ensuring that the reactants can react completely and providing a stable and constant temperature reaction environment for the acid leaching reaction device and the alkali dissolution reaction device.

[0021] Optionally, the acid immersion reaction device, the alkali dissolution reaction device, and the adhesive preparation device are respectively equipped with an acid immersion stirring device, an alkali dissolution stirring device, and an adhesive stirring device.

[0022] By adopting the above technical solution, a stirring device is provided in the acid leaching reaction device, the alkali dissolution reaction device, and the adhesive preparation device. This allows the stirring device to uniformly and fully stir and mix the materials in the adhesive preparation device, thereby accelerating the dissolution and reaction process between the materials and improving the overall reaction rate.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The acid slag separated by the first solid-liquid separation device is converted into crude sodium silicate solution through a conversion module. This allows the external alkaline solution and acid slag to be fully mixed and reacted in the alkaline dissolution reaction device. Then, the alkaline solution and alkaline slag are separated by the second solid-liquid separation device. The crude sodium silicate solution after solid-liquid separation is then transported to the adhesive preparation device through the crude sodium silicate solution pipeline. This enables the self-produced adhesive to be used as a raw material for the subsequent preparation of carbon-based adsorbents. Through structural integration and process optimization, both gasification fine slag and desizing slag are converted into raw materials or products within the system, achieving the synergistic treatment of the two solid wastes. This results in internal circulation and near-zero emissions during the treatment of the two solid wastes, and improves the processing efficiency and control precision of the equipment, providing a feasible path for the resource utilization of the two solid wastes.

[0024] 2. A second conveying mechanism is provided between the first solid-liquid separation device and the alkali dissolution reaction device, which enables the acid slag to be transported from the acid slag outlet to the alkali dissolution solid feed inlet. This allows the acid slag generated during the gasification fine slag treatment process to be utilized. The acid slag can then enter the conversion module to provide raw materials for the preparation of sodium silicate crude solution, reducing the steps required for acid slag treatment by the manufacturer and bringing higher economic benefits.
