Abstract
A nozzle for liquid column jetting flue gas desulfurization tower comprises an injection orifice, transition section connected with the injection orifice and flange connected with the transition section and is structurally characterized in that, the inner walls of the injection orifice and the transition section are smoothly connected, the inner wall of the injection orifice is cylindrical, and the inner wall of the transition section is trumpet shape which guarantees small resistance and has strong abrasion resistance. The entire inner wall of the upper transition section of the injection orifice is provided with 4 to 8 vertical rotational flow-shaped internal grooves. The utility model effectively enhances the spraying effect of the nozzle, reduces greatly the input costs, improves antisepsis and wear resistance of the nozzle, and extends the service life. Compared with the prior art, the nozzle is easily processed and arranged and has a simple structure and is in particular suitable for liquid column jetting flue gas desulfurization tower.
Description
The utility model is used for the injection apparatus of the desulfurizing tower of SO 2 from fume purification techniques, relates in particular to the nozzle of liquid column-spraying fume desulfurizing tower.
Can at present, in the liquid column-spraying fume desulfurizing system, the desulfurizing agent nozzle be vital parts, be one of factor of the desulphurization system decision that obtain excellent desulfurizing effect and operation steady in a long-term.Because the liquid column-spraying fume desulfurizing technology adopts lime slurry as desulfurizing agent more, and nozzle is in the environment that the Acidity of Aikalinity high-frequency changes for a long time, therefore, the design of nozzle and the selection of material all proposed very high requirement.In the prior art, generally there is the cost height in the nozzle that liquid column-spraying fume desulfurizing tower adopts, and atomization is poor, and anti-corrosive properties and wearability are low, the shortcoming that service life is short.
At the shortcoming that exists in the above-mentioned prior art, the utility model has designed a kind of nozzle that is used for liquid column-spraying fume desulfurizing tower.It can improve the nozzle atomization effect effectively; Reduce input cost greatly, the anticorrosion antiwear performance of nozzle prolongs its service life.
The technical solution of the utility model realizes in the following way:
The nozzle that is used for liquid column-spraying fume desulfurizing tower, the changeover portion that it is joined by jet and jet reach the ring flange that joins with changeover portion to be formed, and ring flange is provided with connecting hole.Its design feature is the inwall smooth connection of described jet, changeover portion.The jet inwall is cylindric, and the changeover portion inwall is can guarantee that resistance is little, strong horn-like of wearability.On the full inwall of jet and changeover portion, be provided with many eddy flow shape inside grooves of vertically offering.
According to above-mentioned technical scheme, the line style of described eddy flow shape inside groove is multi-form inner vortex, and the quantity that its corner is not more than 180 ° of eddy flow shape inside grooves is 4 to 8; The aperture dimension of described jet is 20mm-200m, and the bottom surface height dimension from the end face of jet to ring flange is 20mm-200mm.
The utility model is owing to adopted the said structure form, be that the jet inwall is made as special curved surface, again can be according to different technological requirements, the line style of eddy flow shape inside groove can be designed as multi-form inner vortex, therefore can guarantee that resistance is little, improve the wearability and the atomizing effect of nozzle, its life-span is prolonged.Experiment learns that under certain jet velocity, when liquid-column height was 4m-12m, the atomizing particle particle size range of nozzle was 0.1m-3mm.Compare with prior art, the utlity model has handling ease, simple in structure, the anticorrosion antiwear cost is low, the characteristics that atomizing effect is good.Being particularly suitable for liquid column-spraying fume desulfurizing tower uses.
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further.
Fig. 1 is the utility model structure chart;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the upward view of Fig. 1.
Referring to Fig. 1-Fig. 3, the ring flange 1 that changeover portion 4 that the utility model is joined by jet 3 and jet 3 and changeover portion 4 join is formed, and ring flange 1 is provided with connecting hole 2, jet 3, changeover portion 4 and ring flange 1 integral body and is connected.Whole material is made up of sour gas corrosion such as the slurries that contain dilute sulfuric acid, watery hydrochloric acid and SO2, NO2, HCL and anti abrasive material, as zirconia, silicon nitride, special cermacis and special plastic etc.The inwall smooth connection of jet 3, changeover portion 4.Jet 3 inwalls are cylindric, and changeover portion 4 inwalls are can guarantee that resistance is little, the bell mouth shape that wearability is strong.On the full inwall of jet 3-5 changeover portion 4, be provided with 4 to 8 eddy flow shape inside grooves of vertically offering 5.The line style of eddy flow shape inside groove 5 is multi-form inner vortex, and the aperture dimension that its corner is not more than 180 ° of jets 3 is 100mm, and very little to the bottom surface vertical scale of ring flange 1 from the end face of jet 3 is 100mm.Occupation mode of the present utility model is same as the prior art, needn't give unnecessary details more.
What be worth proposition is that jet 3 of the present utility model, changeover portion 4 adopt split to be connected with the form of joining of ring flange 1; The aperture dimension scope of jet 3 is got 20mm-200mm; Get 20mm-200mm from end face to the bottom surface height dimension of ring flange 1 of jet 3.The technical scheme that all technical characterictics as described form all belongs to protection domain of the present utility model.
