The utility model has the advantages that the power consumption and the diameter of fog drips are reduced, the uniformity of particle size of the fog drips and the atomization coverage radius are improved, and the self-air-suction double-current high-efficient atomization and desulfurization spray nozzle is applicable to applications of desulfurization and atomization.
Description
Technical field
The utility model is specifically related to a kind of from air-breathing double-current high-efficient atomizing desulfurization nozzle, belongs to the technical field that plant equipment is made, and is adapted to the doctor solution atomizing and uses.
Background technology
Desulfurization nozzle is a core component in the sulfur removal technology, and desulfurization nozzle directly influences desulfurized effect with size droplet diameter size, the particle diameter uniformity and the covering radius of doctor solution atomizing.Desulfurization nozzle commonly used is spiral nozzle, solid tapered nozzle and double-current atomizer.Spiral nozzle is to impact the spiral awl by pressure fluid stream, the atomizing that liquid is realized liquid is broken up in reflection, its need certain pressure (〉=0.25Mpa), its atomizing effect is subjected to the influence of fluid pressure size, it is poor to atomize when pressure is low, and the atomizing covering radius is little, simultaneously because the structure of spiral awl, the spiral taper thread grinding decreases big, easily stops up.Solid-cone (type) nozzle is that pressure fluid stream tangential side is advanced, and makes the atomization of liquid by inner guide vane, and fogdrop diameter is big, and covering radius is little.The double fluid atomizer is used in the semi-dry desulphurization system usually, and it needs extra compressed air as source of the gas, and consumption of power has increased the oxygen content in the flue gas simultaneously.
Summary of the invention
The purpose of the utility model patent is for overcoming above deficiency, provide the existing various desulfurization nozzle atomized drops of solution big, granularity is inhomogeneous, covering radius is little, need power big and need the problem of additional compression source of the gas, can realize that atomized drop is little, epigranular, need not the additional compression source of the gas, what wet method and semi-dry desulphurization can be used is a kind of from air-breathing double-current high-efficient atomizing desulfurization nozzle.
The utility model is to realize like this, described a kind of technical scheme that adopts from air-breathing double-current high-efficient atomizing desulfurization nozzle is to be connected to form by liquid cap 2, gas-liquid mixed post 8, reflection vertebra 15, it is characterized in that liquid cap 2 is by screw thread 7 screwed connections on the mixed column on liquid cap connecting thread 6 and the gas-liquid mixed post 8, gas-liquid mixed post 8 is by screw thread under the mixed column 12 and 13 screwed connections of reflection vertebra connecting thread, and reflection vertebra connecting thread 13 is connected on the reflection vertebra 15 by joint pin 14; Liquid cap 2 is provided with air inlet transom window 5, conduit 3, conduit vertebra mouth 4 and liquid cap connecting thread 6; Be sequentially set with in the gas-liquid mixed post 8 and reduce mouth 9, aditus laryngis 10 and flaring mouth 11, reflection vertebra 15 is a pyramid type.Desulfurization nozzle is connected to form by liquid cap, gas-liquid mixed post, reflection cap.The liquid phase cap is cylindrical, connecting thread or adpting flange are arranged at top, and (caliber adopts screw thread smaller or equal to 2 inches, adopt flange greater than 2 inches), there are hollow conduit and conduit vertebra mouth in the centre, and liquid phase cap bottom conduit vertebra mouth and connecting thread form inside and outside twice loop configuration.Sweetening liq stream flows in the conduit in the liquid phase cap, and liquid phase cap conduit vertebra mouth slightly closes up, and forms high-speed desulfuration liquid stream, and doctor solution flows to into the gas-liquid mixed post.The gas-liquid mixed post is provided with the air inlet transom window, reduces mouth, aditus laryngis, flaring mouth and two ends connecting thread up and down.In the gas-liquid mixed post because the effect of high speed liquid phase stream, in the gas-liquid mixed post, form negative pressure, air inlet transom window by the gas-liquid mixed post sucks extraneous gas, owing to reduce progressively compressed mixed of mouthful effect gas-liquid, and form turbulent flow, reach gas-liquid mixed and dispersing liquid in aditus laryngis portion, in of the release of flaring mouth owing to pressure, liquid further disperses, and forms the aqueous vapor atomized flow, the epigranular of liquid dispersion atomizing.Impact on the reflecting plate of reflection cap behind the gas-liquid mixed stream ejection gas-liquid mixed post, the further fully atomizing of drop that makes liquid and atomized forms tiny, uniform droplet, has increased the contact area of doctor solution and flue gas, has improved assimilation effect.The reflection cap is made up of reflection vertebral plate and connecting thread.Reflection vertebral plate angle can adopt 90 °, 120 ° and 150 °.Distance is how regulated by connecting thread between reflection vertebral plate and gas-liquid mixed column flaring mouth.Can reach best atomizing effect and covering radius like this.
Of the present utility model a kind ofly have the abundant atomizing that has realized doctor solution by gas-liquid mixed from air-breathing double-current high-efficient atomizing desulfurization nozzle, and atomizing particle size is thin, epigranular, covering radius are big; Form gas-liquid mixed, aerosol dispersion doctor solution saving power by the energy that utilizes doctor solution self, need not the additional compression air; The assembling of employing modularization, clean and maintenance, replacing convenience, renewal cost is low.
