Description
Technical Field
A device for recovering powdery resources. In particular to a recovery device for recovering powdery resources loaded in flue gas.
Background
Many resources exist in a powder state, particularly in the manufacturing process, dry preparation is a simpler way, but the microparticle dust state resources are loaded in smoke and are difficult to capture, because the microparticle dust state resources are easy to escape and lose and even form pollutants, particularly resources such as beryllium, lead, tin, cadmium, zinc, manganese, nickel and the like, and in the smelting process, the microparticles are extremely small, the value is high, the toxicity is high, and the contradiction between resource collection and pollution control is particularly outstanding. The same problems are faced by plastics, pharmaceutical and cement manufacturing industries. To avoid this contradiction, more complex processes often have to be used, which greatly increases the cost and reduces the resource utilization.
The core problem is to separate these resources from the flue gas carrying them, and the core difficulty is the technical performance problems of the filter for separating flue gas from the fine particulate resources, such as efficiency, wind resistance, dust holding capacity, corrosion resistance, high temperature resistance, etc.
For example, the current common dust removal and recovery technology is electrostatic dust removal and cloth bag dust removal, the highest reported treatment level is a film-covered cloth bag dust remover, and the filtering effect of the cloth bag dust remover can reach 5-7mg/m, and although the value is high, the technology is not enough in terms of resource recovery and pollution control. Particularly, the metal dust such as beryllium, lead and the like has quite high toxicity and must be thoroughly treated, the optimal leakage index is at the level of below 1-30 ug/m, the most strict standard in reality is 5-7mg/m, and the gap is thousands of times from the ideal target. This index can only be achieved up to what is known as an "absolute filter" level in the row, and so the powdery resource recovery means in this sense can be referred to as "powdery resource absolute recovery means".
Conventional 13-14 stage high efficiency filters (hape), commonly used to make "absolute filters" in standard filtration devices, have extremely high hape windage; the energy consumption is very high; the dust holding capacity is very small and can be easily blocked, so that the dust holding capacity needs to be replaced frequently, and the operation cost is very high, and the defects make the traditional hape unsuitable for manufacturing the recovery and filtration equipment of the powdery resources in the mass production process.
The 2018 national intellectual property agency accepted the Guo Shaohua application for a hollow fiber membrane module for treating high dust gas and its application structure (2018209712467). Numerous experiments and field applications have shown that this technique can reach levels of 1-10 ug/m, which would be possible to solve the above-mentioned problems if it could be used for powdery resource recovery.
The gas purification and the resource recovery are seemingly the same problems, but the difference between the two is quite clear, the former focuses on the purity of the gas, and the latter pursues the recovery of powdery resources. With respect to the differences, the device configurations involved will vary. For example, in the conventional membrane modules, the spacing between membrane wires is very small in order to pursue packing rate, but the membrane modules for resource recovery must appropriately increase the spacing between membrane wires to avoid dust accumulation, which also puts new demands on the structure.
Therefore, the absolute recovery device of powdery resources which can reach the microgram level is a new design which needs innovation.
