Abstract
The utility model relates to a feeding spray nozzle, and provides a feeding spray nozzle for particle containing fluid. The feeding spray nozzle comprises a feed opening device provided with a baffle plate, a rotary mixing cavity pipe, a tapered pipe and a spray nozzle; one end of the feed opening device is connected with the tangent of the upper part of the rotary mixing cavity pipe; the large end of the tapered pipe is connected with the lower end of the rotary mixing cavity pipe; and the spray nozzle is connected with the small end of the tapered pipe. After the liquid disperses and spills, the gas-liquid phase mass transfer area is large, the separation speed is high, and the liquid phase covers the generated foam downwards with the gravity; and the foam killer in the liquid phase is combined with the foam in the even dispersion manner, so as to enhance the defoaming effect. Moreover, the particle entrainment of the discharged gas phase can be reduced due to the favorable dispersivity, so that the discharge rate of the gas phase is increased, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of charging shower nozzle.
Technical background
Contain the VCM monomer in the slurry that the PVC polymerisation forms, need analyse removal by taking off.Take off the process of analysing and comprise the dispersion of slurry feed, defoamer.
For slurry feed, slurry directly enters by pipeline in the liquid phase of deaerating tank or enters along the inwall of deaerating tank, and charging aperture does not possess the performance of impelling fluid to disperse.Cause the specific area of fed slurry little, mass transfer rate is low, is unfavorable for the separation of gas-liquid phase in the slurry.
Deaerating tank is a low pressure vessel, and gas-liquid two-phase separated after slurry entered container, and liquid phase forms foam easily, is accompanied by carrying secretly of pulp particle in the process that gas phase is removed, and the aperture control gas phase rate of discharge of air bleeding valve influences the amount of carrying secretly of particle in the gas phase simultaneously.In present production technology, defoamer and slurry mix direct charging, and the breaking foam effect is little; Other does not have additional measures to reduce particle entrainment, has only by reducing gas phase velocity to reduce particle entrainment.The reduction of gas phase rate of discharge has a strong impact on slurry and takes off and analyse speed, final decision the quantum of output of whole production system.
Though conventional shower nozzle has the performance of dispersion soln, contain a large amount of polyvinyl chloride particles in the slurry, easily stop up the space, can not use in the dispersion that applies to slurry.
Summary of the invention
The purpose of this utility model provides a kind of charging shower nozzle that is used to contain granule fluid, to overcome the above-mentioned defective that prior art exists.
This practical novel charging shower nozzle comprises the charging aperture device, rotation mixing cavity, reduced pipe and the nozzle that are provided with dividing plate;
One end of described charging aperture device is connected with the top tangent line of rotation mixing cavity, and the big end of described reduced pipe is connected with the lower end of described rotation mixing cavity, and described nozzle is connected with the small end of reduced pipe.
Charging shower nozzle of the present utility model, reducing by charging aperture and dividing plate change the energy that slurry and defoamer enter the rotation hybrid chamber, increase its rotation function.The rotation hybrid chamber mixes slurry and defoamer, the kinetic energy of part vertical direction is transferred to the kinetic energy of horizontal tangent direction.The reducing structure of nozzle has further increased the speed of slurry and defoamer, fluid is sprayed dispersedly with maximum area ground cover deaerating tank.After fluid disperseed to spill, gas-liquid phase mass transfer area was big, and separating rate is fast, the foam that liquid phase has produced with the downward covering of gravity; Defoamer in the liquid phase evenly strengthens in conjunction with defoaming effect with foam dispersedly.Good dispersive property has reduced the particle entrainment of discharging gas phase, increases the rate of discharge of gas phase, and production efficiency is improved.
