Background technology
Alumina article, especially high purity aluminium oxide, be one of base mateiral of high-tech area, because it has the characteristics such as high-melting-point, high rigidity, insulation be heat-resisting, be widely used in the various engineering such as aerospace, nuclear energy, the energy, metallurgy, electronics, biological chemistry, chemical engineering.It is a kind of rising product.Developed more than ten kinds abroad and produced method high-purity, ultra-fine alumina, and had batch production, and high-purity, ultra-fine alumina is prepared in the thermolysis of domestic main employing tschermigite.This method produces corrosive gases in process of production, and environment and equipment are caused to serious harm.
In recent years, domestic Application Areas high-purity, ultra-fine α-Al2O3 is widened rapidly, and the aluminum oxide High-tech Material production line introducing and digest and assimilate increases, and makes high-purity, the research of ultra-fine α-Al2O3, exploitation become a very active field.Produce can make a profit 10 times of metallurgical-grade aluminum oxide of the magnitudes such as profit is of 1t multiform alumina, even 100 times, can create appreciable economic benefit.Therefore, develop rapidly a kind of low cost, competitive novel method high-purity, ultra-fine α-Al2O3 seems particularly important.High purity alumina powder has become the large important branch of one in advanced ceramic, has been one of high-end material industry that in new material industry, output is large, the output value is high, purposes is wide since 20th century.The developed countries such as American-European and Japan are doing a large amount of work aspect the research of aluminum oxide and production.Technology, in first place in the world, has formed mass-producing batch production.
The production method of current domestic high purity aluminium oxide mainly contains neutralization precipitation method, spray pyrolysis, and freezing gel method, organoaluminum alkoxide hydrolysis, organic alkoxide hydrolysis method is owing to there being distilation technique, and the quality product that the method is produced is best.
Yin Wendu in the synthesis procedure of organic alkoxide working system Virahol and reactive aluminum, that the time is controlled is improper, easily produce sharply reaction of moment initiation, thereby formation bumping, the alkoxide that makes a large amount of isopropyl alcohol liquids and reacted generation is gone out outside tower by straight tube condensing tower, causes financial loss.
Utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of alkoxide process to produce the anti-bumping device in high-purity alpha-alumina building-up reactions.
The utility model comprises synthesis reactor, condensing tower, anti-bumping tank body, described anti-bumping tank body is communicated with by pipe connecting with described condensing tower, described anti-bumping tank body is communicated with described synthesis reactor by reclaiming alcohol pipe, at described anti-bumping tank body, cooling water jecket is set outward, the baffle plate that multiple-layer horizontal arranges is set in described anti-bumping tank body, the area of described each baffle plate be not more than described anti-bumping tank body sectional area 3/4ths, condensing coil is set below described each baffle plate, described each condensing coil is close to described each baffle plate, described each baffle plate, condensing coil staggered arrangement forms the bumping material runner being communicated with, the upper end of described anti-bumping tank body sets out gas port, the upper and lower part of described cooling water jecket arranges respectively cooling water outlet, entrance of cooling water.
The utility model is by having increased anti-bumping tank body on the basis at original synthesis reactor, condensing tower, baffle plate in anti-bumping tank body and condensing coil play the effect that stops overheated bumping material and cooling bumping material, the loss of material that the use of anti-bumping tank body can avoid bumping to cause, has avoided financial loss.
Volume in anti-bumping tank body described in the utility model between a bottom baffle plate and described anti-bumping tank body bottom surface is not less than 1.5 times of described synthesis reactor volume; This set can absorb bumping material in synthesis reactor, the loss of avoiding completely.
