Description
Technical field
This utility model relates to a kind of efficiently double end unidirectional atomization desulfurization nozzle, is specifically related to the novel sintered nozzle of flue gas desulfurization industry.
Background technology
Desulfurization nozzle, as a kind of key equipment in desulphurization system, is the key factor affecting desulfuration efficiency.Its function is to make limestone liquid form certain angle to eject, and makes the liquid atomization into the droplet that design is wanted, thus effectively removes the sulfur dioxide in flue gas.Desulfurization nozzle has the several key parameter of flow, angle and atomizing particle size, and angle determines coverage rate, and atomizing particle size affects the contact area of liquid and flue gas.In recent years, along with the flow of desulfurization nozzle is increasing, atomizing particle size increases the most therewith, thus decreases desulfurizing agent liquid and the SO in flue gas2Effective contact area, reduce gas liquid reaction speed, reduce system desulfurization degree.Common tangential type nozzle the most increasingly can not meet the needs in market.
Utility model content
The purpose of this utility model is to provide a kind of efficiently double end unidirectional atomization desulfurization nozzle, for substituting the scene that common tangential type nozzle cannot meet, improves coverage and atomizing particle size, improves the effect of desulfuration efficiency.
Promote the secondary-atomizing effect of liquid, promote the reaction efficiency of atomized drop, reduce energy consumption.
The impact velocity that unique reverse eddy-current technique of double end makes adjacent liquid bore improves, and smoke distribution is evenly.
Extend the haptoreaction time of gas-liquid, add the flue gas travel path by spraying layer so that flue gas has more chance to react with drop, improves flue gas desulfurization effect.
For realizing above-mentioned utility model purpose, this utility model takes following design:
A kind of efficiently double end unidirectional atomization desulfurization nozzle, it is characterised in that: include access road, outlet cavity, necking down structure, ejiction opening；
Described access road (1) is and outlet cavity (2, 3) it is connected, the central plane (8) of access road respectively with outlet cavity (2, 3) inner surface is tangent, liquid is the most tangential enters two outlet cavitys (2, 3), centrifugal force is produced by tangential rotation, form eddy current by necking down structure, spouting with certain design angle from ejiction opening, the liquid cone angle of two ejiction openings reversely rotates, simultaneously because under the effect of two outlet angles (θ) on two planar and drift angle (ω), further such that liquid stream produces collision with air at a high speed, and the head-on collision of overlapped part forms secondary-atomizing, obtain less liquid mist microdroplet.
As seen from the above technical solutions, the utility model has the advantages that: by increasing drift angle (ω), optimize the size of angle (θ), add the collision probability of two liquid cones, increase the area coverage of single-nozzle, solve the big technical barrier of high flow capacity atomizing particle size that common tangential type nozzle exists, and novel structure, more convenient to install.
