Embodiment 1

[0082] use Figure 6 When the equipment shown is working, first set the monitoring value range of the pressure sensor to 14.9-15.1Mpa through the chain control system, open the intake control valve, and high-pressure nitrogen enters the pressure vessel through the gas delivery pipeline. When the pressure in the pressure vessel exceeds 15.1 At Mpa, the intake control valve is closed, and at this time, water with a dissolved nitrogen content of 1 ppm is introduced into a pressure vessel filled with 15.1 MPa nitrogen through an atomizing nozzle (stainless steel, 6 mm inner diameter). The water sprayed from the atomizing nozzle is in the form of mist, and the water droplets dissolved in nitrogen are collected at the bottom of the pressure vessel. The collected water exits the pressure vessel through a conduit and is sprayed at the end of the output line through a bundle of borosilicate capillary tubes (inner diameter 5mm) into the tank. The dissolved nitrogen content measured at ...

Embodiment 2

[0085] use Figure 6 When the equipment shown is working, first set the monitoring value range of the pressure sensor to 9.9 ~ 10.0Mpa through the chain control system, and then open the atomizing nozzle and the air intake control valve at the same time to make the aqueous solution containing 5% glucose (D 5 W solution) and nitrogen enter the pressure vessel at the same time, the pressure of the pressure vessel rises gradually, and the D dissolved in nitrogen 5 The W solution was sprayed into the water tank through a bundle of borosilicate capillary tubes (inner diameter 0.5 mm). Under an argon ion laser emitting light at 488 / 515nm wavelength, observe the nitrogen-dissolved D as it exits the capillary nozzle 5 In solution W, no bubbles with a diameter greater than 500 nm were observed. After working for a period of time, the internal pressure of the pressure vessel rises above 10Mpa, the pressure sensor feeds back to the PLC control system, and the intake control valve autom...

Embodiment 3

[0088] use Figure 6When the equipment shown is working, first set the monitoring value range of the pressure sensor to 4.9-5.1Mpa through the chain control system, open the intake control valve, and high-pressure nitrogen enters the pressure vessel through the gas delivery pipeline. When the pressure in the pressure vessel exceeds 5.1 At Mpa, the intake control valve is closed, and water is introduced into a pressure vessel filled with 5.1 MPa nitrogen through an atomizing nozzle (stainless steel, 6 mm inner diameter). The water sprayed from the atomizing nozzle is in the form of mist, and the water droplets dissolved in nitrogen are collected at the bottom of the pressure vessel. The collected water exits the pressure vessel through a conduit and is sprayed into the albumin solution at the end of the outlet line through a bundle of borosilicate capillaries (1 mm inner diameter). Use a submicron particle size analyzer (Tri-Blue Microtrac, Leeds & Northrup Instruments) to che...

Description

technical field [0001] The invention relates to a generating device for introducing protective gases such as nitrogen, helium and argon into a liquid-phase reaction system in the form of nano-scale bubbles, which is suitable for liquid-phase reaction systems requiring protective gases in chemical, pharmaceutical and food processing industries and craftsmanship. Background technique [0002] In many liquid phase reaction systems and processes involved in the chemical, pharmaceutical, and food processing industries, protective gas is usually introduced into the reaction system to prevent the protected substance from being oxidized by oxygen in the air. The introduced protective gas is generally a gas with stable chemical properties and no chemical reaction with the protected substance, usually nitrogen and rare gases (including: helium, neon, argon, krypton, xenon, radon) or other incompatible reactants Reactive gas. [0003] The protective gas is usually introduced into the...
