Abstract

The invention discloses a high-speed centrifugal spray drying process. The high-speed centrifugal spray drying process comprises the steps that after being filtered and heated, the air enters an air distributor at the top of a centrifugal spray dryer and the hot air spirally enters a drying room uniformly; the feed liquid is conveyed to the centrifugal spray dryer and becomes extremely fine vaporous drops after undergoing rotary spraying carried out by a high-speed centrifugal atomizer and the drops come into contact with the hot air in parallel flow; the materials are continuously dried and the finished products are output from discharge holes in the bottoms of the centrifugal spray dryer and a primary dust collector and are collected into a material box; under the action of an exhaust fan, the waste gas in the centrifugal spray dryer is exhausted after the materials are filtered by the primary dust collector, a secondary dust collector and a wet dust collector. The high-speed centrifugal spray drying process has the advantages of reasonable design and high drying speed; the products have good uniformity, flowability and solubility and high purity; adherence of heat sensitive materials to walls is not easily caused when the process is used for processing the heat sensitive materials.

Description

A kind of hig h-speed centrifugal spray drying technique
Technical field
The present invention relates to a kind of hig h-speed centrifugal spray drying technique that is applicable to generate the solid product such as powdery, graininess from solution, emulsion, suspension and pasty state liquid charging stock.
Background technology
In fields such as chemical industry, petrochemical industry, light industry, food, medicine, building materials, potteries, often need to be dried to dry powder to some solution, emulsion, suspension, pasty material, general using spray dryer is realized at present.The technology that traditional spray dryer adopts is to adopt first material to carry out atomization, is then dried by the air after heating, is dried powdered.But there is following weak point in it: 1, can make be heated inequality or be excessively heated and affect the quality of product of product, be not suitable for the processing of heat sensitive material, and be difficult to ensure the color, smell and taste of heat sensitive material; 2, easily sticky wall of material; 3, product degree of being mingled with is high.Therefore, be badly in need of a kind of drying process that can solve above weak point.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of heat sensitive material processing that is applicable to is provided, be not easy to cause material to glue wall, process that purity is high, the hig h-speed centrifugal spray drying technique of the measured product of matter.
The technical solution adopted for the present invention to solve the technical problems is: a kind of hig h-speed centrifugal spray drying technique, has following steps:
A. air fan housing filtration after filtration, passes through heater heating by pressure fan, and setting heating-up temperature is 120~300 DEG C, enters the air distributor at drying machine with centrifugal spray top, and hot-air enters hothouse in the shape of a spiral equably;
B. feed liquid is delivered to drying machine with centrifugal spray through feeding engine from hopper, becomes imperceptible vaporific liquid pearl through high speed centrifugal atomization device rotating spraying, contacts with hot-air stream;
C. the temperature of setting in drying machine with centrifugal spray is 80~100 DEG C, and continuously to dry materials, finished product, from the discharging opening output of drying machine with centrifugal spray and primary dust removing device bottom, is collected material frame;
D. drying machine with centrifugal spray waste gas, under the effect of air exhauster, is discharged after primary dust removing device, secondary ash collector and wet scrubber filter material.
Further, in described step a, heating-up temperature is set as 200 DEG C.
Further, in described step c, the Temperature Setting in drying machine with centrifugal spray is 90 DEG C.
Further, described primary dust removing device is cyclone separator, and secondary ash collector is bag hose, and wet scrubber is foam dust collector.
Further, described heater is steam heater, electric heater, oil burner, gas furnace or coal furnace.
Operation principle: air, through filtering and heating, enters drier top air distributor, and hot-air enters hothouse in the shape of a spiral equably.Feed liquid is through the high speed centrifugal atomization device at tower body top, and rotating spraying becomes imperceptible vaporific liquid pearl, contacts with hot-air stream, within the extremely short time, can be dried as finished product.Finished product is continuously by exporting in drying tower bottom and cyclone separator, and waste gas is emptying by blower fan.
The invention has the beneficial effects as follows: the present invention is reasonable in design, rate of drying is fast, and product has the good uniformity, mobility and dissolubility, and product purity is high, and heat sensitive material processing, is not easy to cause material to glue wall.
Brief description of the drawings
Below in conjunction with accompanying drawing, the present invention is further described.
