Detailed description of the invention
Below in conjunction with accompanying drawing 1, the flue gas purification system of a kind of smelting laterite-nickel ores of the present utility model is described in detail below.
As shown in Figure 1, the flue gas purification system of a kind of smelting laterite-nickel ores of the present utility model, its structure includes the air inlet pipe 1 being external in flue gas discharge port, the reverse-flow spiral cooling device that flue gas is cooled down and the smoke eliminator that flue gas carries out udst separation; Described air inlet pipe 1 and the downward-sloping setting of reverse-flow spiral cooling device, described smoke eliminator is horizontally disposed with, the higher-end of reverse-flow spiral cooling device is communicated in air inlet pipe 1, the relatively low side of reverse-flow spiral cooling device is communicated in smoke eliminator by bend pipe 8, and flue gas discharges after being flowed through reverse-flow spiral cooling device, smoke eliminator successively by air inlet pipe 1.
Cooling tube 2 that described reverse-flow spiral cooling device includes having toroidal cavity 3 and be arranged at cooling tube 2 internal driven by motor 7 and with the helical axis 6 of cooling tube 2 coaxial line; It is communicated with cold air air inlet pipe 4 above the relatively low side of described toroidal cavity 3, this external air refrigerating devie of cold air air inlet pipe 4, it is communicated with cold air escape pipe 5 below the higher-end of described toroidal cavity 3; One end of described helical axis 6 is through the protruding motor 7 that is connected to of bend pipe 8, and when motor 7 drives helical axis 6 to rotate, the helical axis 6 that the flue gas of entrance air inlet pipe 1 is rotated sends into smoke eliminator.
Described smoke eliminator includes casing 9, is arranged at the automatic sprayer 11 above casing 9 and is arranged at the collection basin 12 below casing 9;Described casing 9 is arranged below bracing frame 10, and the bottom centre position of casing 9 offers circular port, collects basin 12 and is sealingly mounted at the circular port bottom casing 9, and collects the open top face upper base surface not higher than casing 9 of basin 12; Offering steam vent 13 on the side that described casing 9 is relative with bend pipe 8, this steam vent 13 is for getting rid of the flue gas of purification; The injection spray pipe 11-1 of described automatic sprayer 11 extends downwardly into casing 9 inner chamber, and injection spray pipe 11-1 is positioned at the surface collecting basin 12.
