With the rapid development of the industry in recent years, the demand for high-purity, ultra-fine metal oxide powders is greatly expanding.

On the other hand, the wet process represented by coprecipitation can produce high- But it has disadvantages in that it is difficult to control the particle size because the production cost is high due to the large number of steps of the production process and the product is generally in a hydroxide form.

Preferably, the oxygen introducing member is configured to heat the gaseous oxygen to a predetermined temperature.

Here, a temperature drop member for lowering the fluid discharged from the heating member to a predetermined temperature before the fluid is introduced into the filter member may be included.

In addition, the filter member may include a first filter member for collecting larger particles and a second filter member for collecting particles smaller than the first filter member.

The apparatus for producing copper oxide powder using the chloride chloride solution according to the present invention comprises an oxygen charging member 10 for charging oxygen at a predetermined flow rate, a chlorofluorocarbon charging member 20 for charging a chlorofluorocarbon waste solution at a predetermined flow rate, A heating member 30 for heating the oxygen and the copper chloride injected by the input member 10 and the chlorinated copper input member 20 to a predetermined temperature and a filter 30 for collecting copper oxide from the fluid discharged from the heating member 30, (40, 50), and a hydrochloric acid separating member (60, 70) for separating hydrochloric acid from the fluid.

The oxygen introducing member 10 is a member for heating the gaseous oxygen and supplying the gas at a flow rate of, for example, 100 to 300 L / min. The oxygen is introduced into the heating member (for example, 30).

A heating line is provided in the oxygen introducing member 10 to heat the gaseous oxygen passing through the oxygen introducing member 10 to the temperature range.

The chlorofluorocarbon charging member 20 is configured to supply liquid chloridized copper (CuCl ₂ ) to the heating member 30 at a flow rate of, for example, 50 to 300 cc / min.

The chlorofluorocarbon injection member 20 may be constituted by an injection device capable of controlling the size of the liquid chlorophilic particle.

The molten copper in the liquid state supplied by the chlorinated-copper injection member 20 is supplied to the heating member 30 by the mixing supply member 32. [

The mixing supply member 32 is supplied with oxygen at a flow rate of 10 to 50 L / min along with the liquid state boron chloride, and the amount of the chlorinated diboride and the gaseous oxygen is adjusted, And the particle size of the chlorocarbon liquid injected into the heating member 30 can be controlled through the heating member 30.

Here, in order to compensate for the lowering of the temperature inside the heating member 30 due to the chloride chloride supplied when the liquid state chloride chloride is supplied into the heating member 30, Is heated to 800 to 900 DEG C and supplied to the heating member (30).

In the heating member 30, a mixture of cupric chloride and oxygen is mixed and heated up to about 1000 캜, whereby a copper oxide powder, chlorine gas and water vapor are formed.

The molten copper chloride solution generated after etching contains a certain amount of water, and is heated together with oxygen in the heating member 30, whereby copper molecules are bonded to oxygen and become copper oxide.

Thereafter, the copper oxide powder, chlorine gas, and steam are discharged from the heating member 30, and the temperature at the time of discharge is lowered to approximately 800 to 900 ° C.

Thereafter, the copper oxide powder, the chlorine gas and the like are first cooled to about 220 to 240 캜 by the temperature lowering member 34.

In the state where the temperature is primarily lowered as described above, the copper oxide powder, the chlorine gas, and the like are put into the first filter member 40 composed of the cyclone filter to filter the copper oxide powder.

The cyclone filter is a device for separating particles by centrifugal force by rotating a passing gas.

The copper oxide powder is primarily collected by the first filter member 40 and the copper oxide powder and the chlorine gas are passed through the second filter member 50 composed of the bag filter secondarily, Thereby collecting smaller particles of copper oxide powder.

The bag filter is a device for collecting minute particles of copper oxide powder contained in chlorine gas and water vapor by providing a bag-shaped filter in a housing and passing copper oxide powder and chlorine gas through the filter.

The second temperature lowering member 52 may also include an expansion valve to expand the gas passing therethrough to lower the temperature or lower the temperature of the chlorine gas by flowing the cooling fluid.

The chlorine gas and the water vapor are separated from the hydrochloric acid and the moisture through the first hydrochloric acid separating member 60 and the second hydrochloric acid separating member 70 for separating water and hydrochloric acid.

The first hydrochloric acid separating member 60 is composed of a device for separating moisture contained in the vapor or gas, and can separate hydrochloric acid by separating moisture from a mixture of chlorine gas and water vapor.

Meanwhile, the second hydrochloric acid separating member 70 comprises a porous adsorbent such as activated carbon, and the hydrochloric acid component that is not captured by the first hydrochloric acid separating member 60 is adsorbed by the adsorbent and recovered.
