Claims (24)

In a device that dissolves gas into liquid:
(a) (i) a pressure vessel that contains liquid and provides an upper space with a regulated gas above the liquid;
(ii) at least one liquid jet nozzle which enables injection into the pressure vessel of the liquid,
(iii) an outlet that allows the liquid to flow out of the pressure vessel ;
Having a dissolving tank,
The (b) the liquid, the dissolving tank to the communication with the at least one liquid jet nozzle, for injecting and means,
(c) said dissolving tank and the gas source communicated,
(d) provided on the outside of the melting tank, the outlets communicating with, a release device, the liquid from the dissolving tank is released into the liquid outside of the discharge device, at least one opening A discharge device comprising :
Comprising a device. The apparatus of claim 1, wherein the gas is selected from the group consisting of air, oxygen, ozone, hydrogen, nitrogen, nitrous oxide, and carbon dioxide. It means for injecting the liquid before Symbol dissolution tank,
(i) a high-pressure liquid pump, or (ii) a wiring source in a residential or industrial setting, or (iii) the pressure of the high-pressure gas replaces the liquid inside the gas, and the liquid is discharged from the outlet. have the ability to force inject the dissolving tank, a plurality of fixed volume container, or (iv) a static liquid column head pressure,
In a device of claim 1, wherein. Pressure outside the discharge device is lower than the pressure in the discharge device, therefore, the saturation concentration of dissolved gases in said release device is greater than the saturation concentration in the region of the discharge instrumentation 置外 claim 1 The device described. The amount of gas dissolved in the liquid, the internal pressure of the dissolution tank, or the contact time with the injected gas in the upper space and the liquid, or thermal means, controlled by, according Item 1. The apparatus according to Item 1. The apparatus of claim 1 , wherein the at least one spray nozzle is adjustable to control a liquid droplet size. The discharge device, the liquid, the liquid processing target that requires at dissolved gases, emitting apparatus of claim 1, wherein. The upper space of the pressurized said gas dissolution tank is to push the liquid containing the dissolved gas from the discharge device, apparatus according to claim 1. Includes entrainment means of the release device is a liquid, whereby liquid containing a gas having the dissolved, the leaves release device, is mixed with the liquid under lower atmospheric pressure, according to claim 1, wherein . Of the discharge device, and the at least one opening and the companion device, the number, size, arrangement, a liquid containing dissolved gas is mixed with more liquid under the atmospheric pressure of the low pressure, and, a gas The device according to claim 1, wherein the device is preset so as to remain substantially dissolved in the liquid. Before Symbol emission device, and at least one opening with accompanying means, number, size, arrangement, and mixed with a liquid which is under atmospheric pressure is at a lower pressure, and a portion of the gas which is at least dissolved the The device according to claim 1 , which is preset to be discharged from the liquid in the form of bubbles. The size of the bubble is controllable size range of Jo Tokoro The apparatus of claim 11, wherein. Of the release device, said at least one opening, number, size, arrangement, the flow rate of the liquid flowing out of the discharge device, and balances the velocity of the liquid flowing into the dissolving tank, thereby controlled pressure When, the ratio of gas volumes of the upper space in the dissolving tank inside the liquid, so they can maintain in a state of steady flow, are set in advance, according to claim 1, wherein. For controlling the operation of the device, has an open-loop or control system closed loop apparatus of claim 1, wherein. In the method of dissolving a gas in a liquid:
(a) a process of filling a sealed container with gas by pressurization;
(b) a process of injecting a liquid into a container containing the gas under conditions where the gas is soluble in the liquid;
(c) a liquid containing a pre Ki溶 loosening gas from the container, and process at least comprises one of the opening and was immersed in the target liquid, leading to the release device,
a liquid containing a gas having; (d) dissolved in the liquid of the target, under conditions that allow the mixing of the liquid between the process of release,
With a method. The method of claim 15, wherein the gas is selected from the group consisting of air, oxygen, ozone, hydrogen, nitrogen, nitrous oxide, and carbon dioxide. Under a pressure of the dissolving tank, the gas, the liquid, dissolved in saturated concentration or saturation concentration near, The method of claim 15. It carried out in continuous mode or pulsed mode, The method of claim 15. The gas enters the vessel substantially at atmospheric pressure, the pre-Symbol liquid prior to releasing from said container, to a higher desired pressure is achieved through the injection of a liquid in a closed system, the gas pressure pressure is method of claim 15.   The method of claim 15, wherein the energy used to pressurize the tank is used to force the liquid containing the dissolved gas to drain into the target liquid and to mix the two liquids. Mixing speed of the liquid, so that the majority of dissolved gas remaining in the solution, being controlled method of claim 15. The method of claim 15 , wherein the mixing rate of the liquid is controlled such that at least a portion of the dissolved gas is released from the solution in the form of bubbles. The size of the bubbles, to a predetermined size range is controlled method of claim 22, wherein. The liquid body from the high-pressure pump enters the vessel, the feedback from the sensor indicative of the level of the liquid which is placed in the dissolution tank, being controlled method of claim 15.
