Embodiment 1

[0045] Embodiment 1 (comparison)

[0046] Microbubble generator structure such as figure 1 As shown, it includes an air inlet pipe 1, a liquid inlet pipe 2, a gas nozzle 3 and a liquid nozzle 4. The inlet pipe and the liquid inlet pipe are rod-shaped, the gas nozzle is arranged at the end of the inlet pipe, the central axis of the gas nozzle coincides with the central axis of the inlet pipe, the liquid nozzle is arranged at the end of the liquid inlet pipe, and the central axis of the liquid nozzle coincides with the inlet pipe. The central axes of the liquid pipes are coincident, the liquid nozzle is located above the gas nozzle, the central axes of the gas nozzle and the liquid nozzle are on the same straight line, and the outlets of the two are opposite. The liquid nozzle adopts a circular tube with an outlet diameter of 4mm, and the gas nozzle is a disc shape (12mm in diameter), and a hole with a diameter of 2mm is arranged on the center of the disc. The distance l betwe...

Embodiment 2

[0048] The only difference from Example 1 is that the liquid velocity of the liquid flowing out of the liquid nozzle is controlled to be 0.88m / s, and the bubbles generated by the microbubble generator are photographed by a high-speed camera, and the microbubble number fraction is 26%.

Embodiment 3

[0050] The only difference from Example 1 is that the liquid velocity of the liquid flowing out of the liquid nozzle is controlled to be 1.33m / s, and the bubbles generated by the microbubble generator are photographed by a high-speed camera, and the microbubble number fraction is 46%.

Abstract

The invention discloses a micro-bubble generator and a gas-liquid reactor containing the micro-bubble generator. The micro-bubble generator includes a gas spraying component and a liquid spraying component. The nozzle, the liquid spraying component includes a liquid inlet pipe and a liquid nozzle arranged on the liquid inlet pipe, and the gas nozzle and the liquid nozzle are oppositely arranged and appear in pairs. The microbubble generator provided by the present invention utilizes the shearing effect of the high-speed liquid jet to break the bubbles multiple times and generate a large number of microbubbles, and uses the impact of the high-speed liquid jet to enhance the dispersion of the bubbles and ensure the gas-liquid mixing effect.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, and relates to a microbubble generator and a gas-liquid reactor comprising the microbubble generator. Background technique [0002] Microbubbles have the characteristics of large specific surface area and strong chemical carrying effect, and are an important means to enhance mass transfer. They have been widely used in the heat exchange and mass transfer process between gas and liquid in the petrochemical field. At present, the methods for microbubble generation mainly include pressurized dissolved air to precipitate bubbles, entraining air to create bubbles, and electrolysis to separate out bubbles. [0003] The pressurized air-dissolving device uses a water pump to provide circulating water with a certain pressure to flow into the pressure air-dissolving tank, and forms a high-pressure gas-water mixed state in the pressure air-dissolving tank to make the gas supersaturated and di...
