Description

Technical Field

[0001] The present invention belongs to the technical field of gas-liquid mixing, and in particular relates to a gas-liquid mixing device, method and application. Background Art

[0002] With the development of society, the scientific community has deeply realized that nanobubbles have extraordinary stability and can become a good gas carrier. Dissolving gas in water in the form of micro-nano bubbles can not only achieve efficient dissolution of gas, but also make bubble water more stable. For the preparation of bubble water, the future development trend is high-concentration nanobubbling. However, the existing conventional physical gas dissolution methods have the following technical disadvantages: 1. Complex operation, large equipment volume, obvious noise, and high energy consumption; 2. The bubbles in the water are large in volume and easy to escape, and it is difficult to maintain high saturation of gas in the water for a long time. For example, high-speed shearing shears bubbles through the high-speed rotation of the impeller, repeatedly cutting large bubbles in the water into micro-nano bubbles, and high energy consumption. The high-speed Venturi tube has low energy consumption, and there are a large number of flow sections in the tube. The flow section is composed of flow channels of different sizes. The sudden change of the flow channel size will cause the bubbles in the water to be repeatedly squeezed. After multiple diffusion and swirl, a gas-supersaturated aqueous solution is finally produced. Because it cannot be sheared at high speed inside, although the energy consumption is low, the microbubble particle size is large, and repeated cycles are required to prepare high-concentration micro-nano bubbles.

[0003] Therefore, seeking an efficient, gentle and safe dissolved gas mode to prepare high-concentration bubble water, and even high-concentration nano bubble water, will help to further broaden the application areas of bubble water and have important practical significance for the development of my country's bubble water industry.

[0049] A gas-liquid mixing chamber 4, wherein the gas-liquid mixing chamber 4 is used to mix the gas and the atomized liquid, and the internal pressure of the gas-liquid mixing chamber 4 is 0.1-0.2 MPa;

[0050] The atomizer 1 is arranged inside the gas-liquid mixing chamber 4, the gas storage chamber 2 is arranged on one side of the gas-liquid mixing chamber 4, the liquid storage chamber 3 is fixedly installed on one side of the gas-liquid mixing chamber 4, and a valve 7 is fixedly connected to the top of the gas-liquid mixing chamber 4, the gas storage chamber 2 is connected to the gas making chamber 8 through a pipeline, the inner wall of the gas-liquid mixing chamber 4 is fixedly connected to the liquid level control chamber 9, a gas inlet 41 and a liquid inlet 42 are arranged inside the gas-liquid mixing chamber 4, and a gas-liquid mixture outlet 43 is arranged at the bottom of the side of the gas-liquid mixing chamber 4.

[0055] The gas-liquid mixing chamber 4 is fixedly connected with a liquid pump, and the atomizer 1 is arranged at the liquid outlet of the liquid pump. In this embodiment, the gas-liquid mixture in the gas-liquid mixing chamber 4 is repeatedly sprayed, which helps the gas in the gas-liquid mixing chamber 4 to continuously dissolve in the gas-liquid mixture.

[0056] Embodiment 3

[0057] The technical features of this embodiment that are different from those of the second embodiment are:

[0062] Embodiment 5

[0063] The technical features of this embodiment that are different from those of the fourth embodiment are:

[0064] The atomizer 1 includes a mounting tube 101, a sleeve 102 threadedly connected to the end of the mounting tube 101, and a collar 103 fixedly installed on the inner wall of the mounting tube 101, a card ball 104 is clamped between the sleeve 102 and the collar 103, the card ball 104 is hollow, and an atomizing nozzle 105 is fixedly connected to the outer wall of the card ball 104, a water inlet hole 106 and a slide groove 107 are opened at the lower end of the card ball 104, a mounting rod 108 is fixedly connected to the inner wall of the mounting tube 101, a mounting plate 109 is fixedly connected to the middle part of the mounting rod 108, a transmission shaft 110 is rotatably connected to the mounting plate 109, a paddle 111 is fixedly connected to the lower end of the transmission shaft 110, a slider 112 is fixedly connected to the upper end of the transmission shaft 110, and the slider 112 is clamped inside the slide groove 107.

[0066] The side wall of the slider 112 is provided with a plurality of grooves 116 , and the grooves 116 can increase the friction between the slider 112 and the ball 104 .

[0067] As can be seen from the above, after the user starts the liquid pump, the liquid pump drives the water flow to impact the paddle 111 and drives the paddle 111 to rotate, and the paddle 111 then drives the transmission shaft 110 to rotate, and the transmission shaft 110 drives the card ball 104 and the atomizing nozzle 105 to rotate through the slider 112. At this time, the user can adjust the position of the slider 112 inside the slide groove 107, and then rotate the positioning bolt 115 so that the two ends of the slider 112 are opened outward and abut against the inner wall of the slide groove 107. At this time, the friction between the slider 112 and the card ball 104 increases, and they no longer slide against each other.
