Description

The whirlwind desulfation dust-extraction device

The utility model relates to dust arrester, is specially a kind of whirlwind desulfation dust-extraction device.

In recent years, all there is the cost height in various desulfation dust-extraction devices, efficient is low, effect is undesirable.

The purpose of this utility model be to provide a kind of simple in structure, with low cost, efficient is high, the whirlwind desulfation dust-extraction device of long service life.

The purpose of this utility model is achieved in that the plane is 160-350mm to distance between the hydrojet endless tube 12 on the scroll casing type gas approach body 48, on the hydrojet endless tube 12 spray orifice is arranged, the double row of spray orifice, the spray orifice position interlocks and angle α, β is arranged, splitterr vanes 18 are ψ with air-flow rotation direction angle, two base angles of reaction cone 39 are θ, and the even distribution angle of eddy flow plate 20 circumference is α.The α angle of spray orifice is 12 °-15 °, and the β angle is 15 °-20 °, and the θ angle is 65 °-75 °, and the ψ angle is 32 °-35 °, α _oThe angle is 45 °-72 °

Advantage of the present utility model is: simple in structure, with low cost, desulfurization and dedusting is an one, and desulfurized effect is 75-85%, and efficiency of dust collection is 92-98%.
