Specific embodiment
First embodiment of the invention is illustrated referring to attached drawing.
< first embodiment >
Referring to Fig.1, liquid CO 2 feedway 100 of the present embodiment is illustrated.Liquid titanium dioxide
Carbon supply device 100 has：Gas bottle 10, pipeline L1, valve 12, liquid CO 2 bottle (carbon dioxide bottle) 20, outlet
22, valve 24, pipeline L2.
The gas of the accumulation high pressure of gas bottle 10.For the type of gas, as long as not having no spy with carbon dioxide reaction
It does not limit.Such as nitrogen, air, argon, helium can be enumerated etc..As long as the pressure of gas bottle is higher than liquid CO 2 bottle 20,
Such as 10~15MPa can be set as.
Gas bottle 10 is connect by pipeline L1 with liquid CO 2 bottle 20.Control is provided in pipeline L1 from gas bottle 10
The valve 12 of the amount of the gas supplied to liquid CO 2 bottle.
Liquid CO 2 bottle 20 is the pressure vessel for accumulating the carbon dioxide of liquid.Liquid CO 2 bottle 20 is maintained
In the temperature condition of the gas-liquid interface I generated in internal formation by carbon dioxide.The example of preferred temperature is -50~31 DEG C,
Meter pressure is 0.68~7.4MPa.In the case where temperature is 31 DEG C or more, there is no shape in the inside of liquid CO 2 bottle 20
At gas-liquid interface I, the carbon dioxide inside bottle becomes supercriticality, therefore is not suitable for.It as needed, can be to liquid two
Thermoregulator 26 is arranged in carbonoxide bottle 20.Liquid CO 2 bottle 20 has outlet 22.Outlet 22 is by liquid titanium dioxide
End in liquid CO 2 bottle 20 is configured the gas-liquid interface in liquid CO 2 bottle 20 by the inside and outside connection of carbon bottle 20
Under I.The other end of outlet 22 is exposed to the outside of liquid CO 2 bottle 20, connect with pipeline L2.It is set in pipeline L2
It is equipped with valve 24.
Next, being illustrated to the application method of the liquid CO 2 feedway 100.
In the state of closing valve 12,24, according to temperature come the pressure in regulation liquid CO 2 bottle 20.Example
Such as, if it is 20 DEG C, gauge pressure becomes about 5.7MPa, and absolute pressure becomes 6.7MPa.Next, valve 24 and valve 12 are beaten
It opens.Thus the gas in gas bottle 10 is supplied to liquid CO 2 bottle 20, by the liquid two in liquid CO 2 bottle 20
Carbonoxide squeezes out, and supplies via outlet 22, pipeline L2 to mixer 8.Two usually can be adjusted using the aperture of valve 12
The flow of carbonoxide, it is possible to use valve 24 adjusts flow.Using gas to the liquid titanium dioxide in liquid CO 2 bottle
The pressure that carbon is given is indicated with gauge pressure, can be set as 0.68MPa or more, can be set as 3.5~14.7MPa.The pressure and utilization
The pressure to be administered such as plunger pump (such as 3.5~14.7MPa) is same.
It, can be the case where not using the high-pressure pumps such as plunger pump using such liquid CO 2 feedway 100
Under just steadily by the liquid CO 2 in liquid CO 2 bottle 20 to externally supplying.Using the high-pressure pumps such as plunger pump
In the case where, if processing capacity becomes 300m3/ more than day, then become the first manufacture.On the other hand, liquid CO 2
Feedway 100 is equivalent to the Liquid Level Pressure in the container of high pressure gas manufacturing equipment, and processing capacity is considered as 0m3/ day, therefore at
It is manufactured for second, legal procedure simplicity when carrying out high pressure gas manufacture cause is just enough.In addition, due to without using high price
The high-pressure pumps such as plunger pump, therefore installation cost etc. becomes cheap.In addition, if the flow of carbon dioxide is easy using plunger pump
Pulsation is generated, but the flow of carbon dioxide is not easy to pulse in the present embodiment.
Then, the painting device 200 for having such liquid CO 2 feedway 100 is illustrated.Coating dress

Solvent tank 30 accumulates solvent.As solvent, such as it can also accumulate the painting of the painting device 300 of the 1st embodiment
A part of solvent contained in the coating of batch can or the solvent different from the solvent.The example of solvent and the 1st embodiment party
Formula is identical.
31 pairs of pump pressurizes via pipeline L5 from the solvent that solvent tank 30 is supplied.The degree of pressurization can with pump 2 phases
Together.
Accumulator 32 absorbs the pulsation of the pressure in the system generated by pump 31.
Mixer 33 is by the carbon dioxide supplied via pipeline L2 from liquid CO 2 feedway 100 and via pipe
The solvent premixing that line L5 is supplied.
Then, mixer 8 will be supplied via the premix of the carbon dioxide of pipeline L6 and solvent with via pipeline L3
Coating mixing, obtained mixture is supplied via pipeline L4 to sprayer 9.
According to the present embodiment, it also due to having used above-mentioned liquid CO 2 feedway 100, therefore does not use
The elevated pressurization of carbon dioxide pumps (plunger pump etc.), can suitably carry out the coating of the coating comprising liquid CO 2.In addition,
Due to using accumulator 3,32, the pulsation for generating pump 2,31 mitigates, and is able to suppress the flow of carbon dioxide and coating
The variation of ratio, the film being induced by it flatness reduction.
< third embodiment >
Then, the appliance for applying carbon dioxide 400 and painting device 500 being related to referring to Fig. 3 to third embodiment carry out
Explanation.Appliance for applying carbon dioxide 400 of the present embodiment is that the liquid CO 2 being related to from first embodiment supplies
Gas bottle 10, pipeline L1 and valve 12 are removed in device 100, it is real with first other than appliance for applying carbon dioxide 400
It is identical to apply mode.
In the present embodiment, only utilize the pressure in liquid CO 2 bottle 20 by liquid CO 2 via outlet
22 and pipeline L2 is supplied to mixer 8.It is just supplied that is, pressurize to the liquid CO 2 in liquid CO 2 bottle 20
To mixer 8.Thus also without using the high-pressure pumps such as plunger pump just to supply liquid CO 2.Due to not to dioxy
Change carbon pressurization, therefore be not equivalent to the manufacturing equipment of high pressure gas, installation cost etc. becomes cheap.Certainly, it is also difficult to use
The pulsation of the flowing of carbon dioxide when plunger pump.
The 4th embodiment > of <
Then, it is illustrated referring to Fig. 4 painting device 600 being related to the 4th embodiment.Here, only to Fig. 2's
The different aspect of painting device 300 is illustrated.Appliance for applying carbon dioxide 400 of the present embodiment is implemented from second
The liquid CO 2 feedway 100 that mode is related to removes gas bottle 10, pipeline L1 and valve 12, in addition to carbon dioxide supplies
It is identical as second embodiment other than device 400.
In the present embodiment, also only utilize the pressure in liquid CO 2 bottle 20 by liquid CO 2 via outlet
Pipe 22 and pipeline L2 are supplied to mixer 8.It is just passed through that is, pressurize to the liquid CO 2 in liquid CO 2 bottle
By the supply of mixer 33 to mixer 8.Thus also without using the high-pressure pumps such as plunger pump just to supply liquid CO 2.By
In not to carbon dioxide pressurization, therefore it is not equivalent to the manufacturing equipment of high pressure gas, installation cost etc. becomes cheap.Certainly,
The pulsation of the flowing of carbon dioxide when being difficult to happen using plunger pump.
In the present invention, it is not limited to the above embodiment, various deformation forms can be used.For example, upper
It states in embodiment, outlet extends upper and lower but it is also possible to be the form for penetrating through bottle wall.
In addition, accumulator can be arranged in pipeline L2.
