Description

Background technique

In practical industrial applications, some gases need to be dissolved in liquids, but the solubility of most gases (such as oxygen) in water is usually low, and the concentration cannot meet the requirements. Therefore, in the industry, special devices are usually installed at the gas-liquid contact position to make the gas-liquid mixing more smooth. At present, commonly used gas-liquid mixing devices include static mixers and jet mixers. The static mixer is to install and fix various mixing elements in the pipeline to change the flow state of the fluid to achieve the purpose of radial mixing. However, there are contradictions between structure, resistance, adaptability and mixing efficiency in static mixers, and this type of device has weak pressure bearing capacity, and the gas-liquid separation phenomenon occurs immediately after the fluid passes through the mixer, and the overall mixing efficiency is poor. The jet mixer automatically draws air into the mixer through the principle of liquid jet, so that it is forced to mix with the liquid. However, the existing jet mixer adopts a multi-stage or multi-section structure, which makes the manufacturing process of the mixer complicated and the manufacturing cost is high.

Detailed ways

The hydraulic cutting type in-ground leaching agent oxygen mixing device described in the utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 to 8, the hydraulic cutting type ground leaching agent oxygen mixing device described in the utility model includes a flange 1, a connecting pipe 2, a connecting pipe 3, a jet pipe 5, and a jet pipe 2 6. Flange 2 8. Nozzle 4. Gas connecting pipe 7.

Wherein, flange one 1, connecting pipe one 2, connecting pipe two 3, jet pipe one 5, jet pipe two 6, and flange two 8 are sequentially connected, and the adjacent two are threaded. Connecting pipe 1 2, connecting pipe 2 3, jet pipe 1 5 and jet pipe 2 6 are tubular.

The inlet end of the tube inside of the jet tube-5 is trumpet-shaped, and gradually shrinks after being large first and then small. The tube inside of jet tube two 6 is trumpet-shaped, first small and then big and gradually expand until the outlet end. The outlet end of jet tube one 5 has a boss, and the inlet end of jet tube two 6 has a groove, and the boss at the outlet end of jet tube one 5 is embedded in the groove at the inlet end of jet tube two 6 to realize a stable connection.

The inner surface of the flange one 1 is threadedly connected to the inlet end of the nozzle 4, and the outlet end of the nozzle 4 extends to the inside of the connecting pipe two 3, and the oxygen mixing chamber is surrounded by the nozzle 4 and the connecting pipe two 3. The gas connecting pipe 7 is located above the connecting pipe 2 3 , and the gas connecting pipe 7 communicates with the connecting pipe 2 3 .

The outlet front end of the nozzle 4 is located on the same plane as the central axis of the gas connecting pipe 7 . The inner diameter of the outlet end of the nozzle 4 is smaller than the inner diameter of the inlet end of the nozzle 4, and is smaller than the inner diameter of the inlet end of the jet pipe one 5, and is much smaller than the inner diameter of the connecting pipe one 2.

Flange one 1, nozzle 4, connecting pipe one 2, connecting pipe two 3, jet pipe one 5, jet pipe two 6 and flange two 8 have the inner diameter central axes coincident.

When using the hydraulic cutting type in-ground leaching agent and oxygen mixing device described in the utility model: connect one end of flange one 1 to the upper flow direction of the liquid injection pipeline, one end of flange two 8 to connect the lower flow direction of the liquid injection pipeline, and the gas connection pipe 7 Connect the oxygen injection tube. Because the fluid is ejected from the nozzle 4 at a high speed, a negative pressure is generated at the gas connecting pipe 7 and the connecting pipe 2 3, and oxygen is sucked into the oxygen mixing chamber from the gas connecting pipe 7. When the flow rate is constant, since the inner diameter of the nozzle 4 is smaller than the inner diameter of the oxygen mixing chamber, according to the Bernoulli equation, the flow rate of the fluid in the oxygen mixing chamber will decrease, and the pressure will increase, thereby increasing the solubility of oxygen; the connecting pipe 2 3 and the jet The inner diameter of the joint of pipe one 5 becomes smaller, and the high-pressure fluid produces vortex mixing at the joint. Both fluid pressure increase and vortex mixing can increase the amount of dissolved oxygen, so as to achieve the purpose of oxygen mixing.
