A neutron beam source generator is provided, which includes an accelerator connecting to a beryllium target through a channel, a filter and a collimator. The beryllium target is disposed at an end of the channel and adjacent to the filter. The filter is disposed between the beryllium target and the collimator. The channel and the beryllium target have an angle &#x3b1; therebetween, and the angle &#x3b1; is between 0&#xb0; and 90&#xb0;. The channel and the direction normal to the surface of the filter have an angle &#x3b2; therebetween, and the angle &#x3b2; is between 0&#xb0; and 90&#xb0;. The cross-section of the channel is not circular.

A vertical and a horizontal vacuum sublimation apparatus with high efficiency and processes thereof are provided, especially for the materials with high melting point and low vapor pressure. The vertical sublimation purification apparatus comprises a sublimation channel body, a material rack, a heating evaporation device, a condensation device, an incubating device, and a product scratching device. The horizontal sublimation purification apparatus comprises a sublimation channel body, a material carrier, a heating evaporation device, and two end pipes. The apparatuses of the present invention can be applied to the mass production of high purity chemicals, and are capable of sublimating and purifying OLED illumination layer materials including Alq, NPB and CuPc, which have high melting temperature and low vapor pressure.

Vertical sublimation apparatus

A reactor containing a plurality of porous rotors is disclosed. A liquid sprayed in a direction from a rotating axis to the rotors is hit by the porous rotors, creating fine liquid particles, so that a mass transfer takes place between the surfaces of the liquid particles and a gas injected into the reactor, and thus a crystallization reaction is initiated. The crystallization reaction is confined by the amounts of the reactants contained in the liquid particles, and will stop as soon as one of the reactants is consumed, so that the resulting crystals can be controlled in nanometer level. The reactor of the present invention is also suitable for use in a liquid-liquid reaction, wherein two different liquids are separately sprayed in a direction from the rotating axis and hit by the porous rotors, and the resulting fine liquid particles of the two different liquids contact and react with each other, so that ultra fine particles are formed.

Reactor for producing ultra fine particles

A high viscosity liquid is fed into a rotation pack bed at a position with a distance far enough from a rotation axis, creating a centrifugal force exerted on the high viscosity liquid overwhelming a drag thereof, so that it can flow radially through the rotation pack bed. A high pressure gas is introduced into the rotation pack bed peripherally and/or a suction force source is connected to a position near the rotation axis, so that a volatile component contained in the high viscosity fluid is entrained in the gas counter currently flowing through the rotation pack bed and withdrawn from the position near the rotation axis, or the volatile component exits from the position near the rotation axis in gas phase, and thus the volatile component is removed from the high viscosity liquid. A second fluid can also be fed into the rotation pack bed to react with the high viscosity liquid, so that a reaction product is formed, and a volatile side product is removed at the same time.
