Abstract
A new spraying drying tower is composed of a wind entering cone, an upper distributing plate, a lower distributing plate, a slurry input nozzle, a cylinder, a wind entering cone-shaped wall, a hot wind inlet pipe, a vertical drawing pole, a centre drawing pole and a horizontal reinforcement rib. The upper distributing plate and the lower distributing plate are arranged horizontally at the cone part between the wind entering tube of the spraying drying tower and the slurry entering nozzle. The upper distributing plate and the lower distributing plate are in the same structure. A plurality of fan-shaped boards are connected with each other to form a circular distributing board. The fan-shaped board is arranged uniformly with vertical downward holes. According to the difference hole opening rate, the wind velocity is controlled, the hot wind flow velocity through the upper distributing plate and the lower distributing plate is almost the same as that of the hot wind velocity of the entering tube, the contact strength of the hot wind and droplets is strengthened, the effect of wind fluidizing is obtained, the holes are uniformly distributed in the tube and the drying ability is improved. The vertical downward multi-hole distributing board controls the air flow downward, changes the moving direction of the slurry droplet spraying of the slurry entering nozzle and avoids the wall viscous phenomenon.
Description
Technical field
The utility model relates to the spray drying technology field, is a kind of novel atomizing drying tower that is provided with distribution grid in spray drying tower wind inlet section cone.
Background technology
Existing spray drying technology, in the spray drying tower wind inlet section cone distribution grid is not set, the wind speed that enters cone inner drying hot blast reduces with the increase of spray drying tower cone diameter, when the slurry atomized drop with the high-pressure nozzle ejection contacts, because due to the factors such as wind speed weakens, skewness, air film can not surround drop rapidly, causes the diffusion rate of drop in air film to reduce, liquid can not be vaporized rapidly, and drying capacity is reduced; And hot blast speed weakens, and can not change the direction of motion of atomizer ejection cone diffused slurry droplet, to the motion of drying tower barrel, causes sticking wall easily.
Summary of the invention
Easily glue technological deficiencies such as wall in order to overcome existing spray drying tower hot blast skewness, material, the purpose of this utility model is to provide a kind of novel atomizing drying tower, promptly in spray drying tower wind inlet section cone, design distribution grid, be used to prevent the sticking wall of slurry and strengthen hot blast uniform, improve spray-drying efficient.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of novel atomizing drying tower is made up of wind inlet section cone, upper strata distribution grid, lower floor's distribution grid, slurry import shower nozzle, cylindrical shell, wind inlet section cone wall, hot blast inlet tube, vertical pull bar, center pull rod.In spray drying tower wind inlet section cone, be horizontally disposed with upper strata distribution grid and lower floor's distribution grid.Upper and lower layer distribution grid is identical with structure, connects the back by 6-24 fanning strip by bolt and forms an annular spread plate, and the fanning strip outside joins and constitutes the distribution grid outer ring, and the fanning strip inner edge joins and constitutes the distribution grid inner ring, and uniform vertical open pores is arranged on the fanning strip.Be provided with the horizontal stiffener identical between distribution grid outer ring and the distribution grid inner ring with fanning strip quantity, the distribution grid outer ring is by being bolted to wind inlet section cone inwall, the distribution grid inner ring then be arranged on spray drying tower wind inlet section cone in center pull rod be connected, upper and lower layer distribution grid and between have 6-24 uniform vertical pull bar to connect, the wind inlet section cone is connected with the drying tower cylindrical shell.6-24 slurry import shower nozzle is uniform along the wind inlet section cone wall, and passes in inducer cone wall and the lower floor's distribution grid feeding cylindrical shell.The hot blast inlet tube is positioned at wind inlet section cone top, and center pull rod is fixed on wind inlet section cone top.
The beneficial effects of the utility model:
By upper and lower layer distribution grid is set,, control its wind speed according to the difference of upper and lower layer distribution grid percent opening between hot blast import of spray drying tower cone segments and slurry import shower nozzle.Generally make by the flow velocity of upper and lower layer distribution grid identical, almost the same with hot blast inlet tube speed, strengthened the contact strength of hot blast and drop, played the fluidisation wind action, and be evenly distributed in the drying tower cylindrical shell, make air film surround drop rapidly, strengthen the diffusion rate of drop in air film, drop is vaporized rapidly and is taken away by hot blast, and drying capacity increases substantially.And distribution grid adopts porous template vertically downward, and control air stream flows vertically downward, not only changed the direction of motion of atomizer ejection cone diffused slurry droplet, and prevented that atomized drop is splashed on the barrel, has prevented wall sticking phenomenon.Wherein the percent opening of double-layer separate fabric swatch is determined according to the cone cross-sectional diameter of placement location, the amount of import hot blast and the hot blast flow velocity of requirement; How much quantity of high-pressure nozzle is determined according to amount of slurry.
