Below in conjunction with the drawings and specific embodiments the utility model is described further.The aspect that the utility model is additional and advantage part in the following description provide, and part will become obviously from the following description, or recognize by practice of the present utility model.
Description of drawings
Fig. 1 is the structural representation of the utility model smoke filtration system.
The specific embodiment
The particle diameter of rhenium in molybdenum ore roast flue gas is substantially between 0.05 μ m to 5 μ m, and therefore the particle diameter of molybdenum oxide, can utilize this character that flue gas is carried out classified filtering substantially between 0.1 μ m to 30 μ m, realizes the enrichment to rhenium.Based on above-mentioned consideration, it is a kind of for the smoke filtration system from molybdenum ore roast flue gas enrichment rhenium that the utility model provides, as shown in Figure 1, this system comprises: the first gas film filter 201, and it is the film filtering element of 1 μ m to 10 μ m that the described first gas film filter 201 adopts filtering accuracy; The second gas film filter 202, it is 0.05 μ m to 2 μ m film filtering element that the described second gas film filter 202 adopts filtering accuracy, the receiving terminal of this second gas film filter 202 is connected with the discharge end of the first gas film filter 201.The use of this smoke filtration system is the molybdenum ore roast flue gas that molybdenum ore roast equipment 1 produces to be fed the first gas film filter 201 earlier filter, it is the film filtering element of 1 μ m to 10 μ m that the first gas film filter 201 adopts filtering accuracy, oarse-grained molybdenum oxide particle can be removed from flue gas; To remain flue gas then and feed the second gas film filter 202, it is 0.05 μ m to 2 μ m film filtering element that the second gas film filter 202 adopts filtering accuracy, therefore the content of rhenium can reach 30% to 50%(mass ratio in the dust of collecting by the second gas film filter 202), thus lay a good foundation for the recovery of follow-up rhenium.Of the present utility model above-mentioned for from the smoke filtration system of molybdenum ore roast flue gas enrichment rhenium, it is the film filtering element of 2 μ m that the described first gas film filter 201 preferably adopts filtering accuracy, make the gas film filter 201 of winning on the basis of collecting molybdenum oxide as much as possible, can not obtain more rhenium again, thereby better guarantee the enrichment of 202 pairs of rheniums of the second gas film filter.It is 0.05 μ m film filtering element that the second gas film filter 202 adopts filtering accuracy, has both guaranteed the molybdenum oxide in the flue gas is removed substantially, again can be because of the too high filter efficiency that influences of filtering accuracy.In addition, the film filtering element in the described first gas film filter 201 adopts chimney filter, the filtration that goes out in advancing outside this first gas film filter 201 is taked for its chimney filter.Film filtering element in the described second gas film filter 202 adopts chimney filter equally, and the filtration that this second gas film filter 202 advances to go out in taking for its chimney filter in order to keep lower filtration flow-rate, guarantees dust removing effects.In addition, the film filtering element of the described first gas film filter 201 or/and the film filtering element of the second gas film filter 202 constituted by inorganic porous material, specifically, the film filtering element of the described first gas film filter 201 or/and the film filtering element of the second gas film filter 202 constituted by a kind of in titanium-aluminium alloy porous material, ferro-aluminum alloy porous material, the nickel alumin(i)um alloy porous material.
