Description
Technical field
The utility model relates to a kind of nozzle that is used for the flue gas ash removal cooling.
Background technology
The known nozzle that is used for the flue gas ash removal cooling is divided into single fluid nozzle and two fluid tips.Single fluid nozzle comprises eddy flow chamber, spinning disk and nozzle head, spinning disk is arranged in the eddy flow chamber, and when work, highly pressurised liquid rotates in the eddy flow chamber by spinning disk, spray by nozzle head at a high speed again, atomizing when ejection, obviously, the atomizing effect that obtain, the speed of liquid ejection is very high, just can make the liquid that sprays from nozzle head have higher flow velocity and only apply higher pressure fluid,, reach 40bar usually so the operating pressure ratio of single fluid nozzle is higher.
Two fluid tip operating pressures are then lower, have only several bar, and its operation principle is to make a kind of liquid and a kind of gas have current difference, and gas is as atomizing medium or Alevaire, and mix with gas liquid broken atomizing back under the flow at high speed of gas is impacted.
Two fluid tips that are used in the flue gas ash removal aspect at present mostly are internal-mixing.Internal-mixing two fluid tips are when work, and two kinds of fluids were just mixed in hybrid chamber before the jetting nozzle head fully.When using compressed air as atomizing medium usually, atomizing effect is fine.But in some cases, it is worthless using compressed air, such as at steel mill, steam is byproduct often, if utilize steam to do atomizing medium, then can play cost-effective effect, and not only can raise the cost but also relatively danger this moment with compressed air, because contain flammable explosive gas in the flue gas.Yet if with steam as Alevaire, two fluid tip working conditions of internal-mixing are very poor because before steam is not also smashed liquid, steam is just soluble in water and condense into water.
Another kind of two fluid tips are outer mixed mode nozzles, different with internal-mixing nozzle, two kinds of fluids behind the jetting nozzle mouth in the jet hole external mix, exterior mixing two fluid tips are under the bigger situation of flow, enough steam flow amounts and steam flow speed must be arranged, just atomizing effect preferably can be arranged, but because air consumption is too big and uneconomical.
