Description

{NANO PARTICLE PRODUCT APPARATUS}

The present invention relates to an apparatus for manufacturing nanoparticles using a micro jet collision, and more particularly, to a nanoparticle manufacturing apparatus using a micro jet collision capable of splitting a substance in a fluid into nanometers by injecting a fluid from the mutually opposing micro- Manufacturing apparatus.

When the material is changed from a micro-unit to a nano-unit, the physical properties can be improved to provide a better function. Recently, techniques for manufacturing metal or non-metal materials in nanoparticle units have been developed.

Most of the methods for producing nanoparticles are chemical production methods. Such a chemical production method includes a vapor phase method of producing nanoparticles in a gas phase, and a coprecipitation method in which desired metal particles are precipitated as a by-product by mixing the metal ions with a solution containing a reducing agent and performing a reduction reaction.

In addition, as a method of producing nanoparticles, there is a vapor phase method using an oven source, and there is a sputtering method in which a target is irradiated with a high energy pulse laser to form gaseous nanoparticles and then cooled.

Physical methods can be used to produce such nanoparticles. As a device using a physical method, there is a spray collision type dispersing device. Such a jet impact type pulverizing and dispersing apparatus is a device for pulverizing and dispersing particles contained in a fluid by pressurizing a fluid containing particles to be pulverized at a high pressure and pulverizing and dispersing the pressurized fluid in a container by collision, shearing, cavitation, .

In the conventional injection collision type pulverizing and dispersing apparatus capable of producing nanoparticles as described above, considerable heat due to high pressure is generated when the fluid collides with each other, so that cooling for the fluid is performed.

At this time, cooling is carried out in such a manner that the fluid is transferred to a separate cooling space connected to the impact space, and then the cooling space is cooled by a separate cooling unit.

However, since the fluid is directly circulated to the cooling unit, foreign matter accumulates on the cooling unit side, or the circulation path of the fluid is contaminated, so that circulation of the fluid is not smooth and the cooling efficiency suddenly drops.

Further, at the time of replacing the fluid jetted by the micro jet, there has been a problem that the cooling unit itself needs to be separately cleaned in order to prevent the impurities from mixing with the exchanged fluid.
