Description
Technical Field
The invention belongs to the technical field of micro-bubble separation in liquid, and particularly relates to a device for separating micro-bubbles in liquid.
Background
Microbubbles are bubbles ranging in diameter from a few microns to hundreds of microns. Industrially, in the production of high-viscosity materials such as high-viscosity liquids, air bubbles tend to be incorporated. These bubbles are broken up to form microbubbles through the stirring or conveying process. The micro-bubbles have small granularity, large specific surface area, slow rise and long duration in the liquid. For example, during the production of high viscosity polymers for enhanced oil recovery, bubbles tend to be formed and mixed in the polymer, and these bubbles are generally small in volume, and in addition, the polymer has a relatively high viscosity, so that the bubbles are normally difficult to escape. These bubbles will be driven into the ground with the injected polymer, which will adversely affect the tertiary oil recovery process, resulting in lower oil recovery efficiency, and the presence of bubbles will cause some contamination of the underground resources, so it is desirable to remove the microbubbles from the injected polymer.
There is inevitably some air in the heating and cooling cycle system, which moves as free bubbles with the liquid circulating in the system. The presence of air therein can have a number of adverse effects on the heating and cooling cycle system: the accumulated gas generates air resistance, so that the system resistance is unbalanced, the system circulation is not smooth, noise and cavitation are generated, the service life of equipment and a pipe network can be shortened, the heat transfer efficiency of the heat exchanger can be reduced due to bubbles attached to the surface of the heat exchanger, the system air resistance causes difficulty in debugging the system, and manual exhaust is often needed during operation. Oxygen in the system can cause oxygen corrosion of the system. The corrosion leads to a reduction in the service life of the system, directly affecting the safety of the whole system.
The publication number CN103056046A discloses a gas-liquid cyclone separation device, which uses a light detection device to detect gas and liquid after gas-liquid cyclone separation, transmits cyclone information to a laser doppler system, and analyzes and processes received data by the laser doppler system. The patent introduces a data analysis system, thereby neglecting the influence of the swirl reinforcement on the gas-liquid separation. The CN201940295U discloses a jacketed gas-liquid cyclone separator, which overcomes the back mixing effect of the original gas-liquid cyclone separator by arranging the shape and the position of a collecting slot, and avoids the adverse effect caused by gas phase entrainment. Meanwhile, the patent adds structures such as a collecting slot, a sleeve and the like, and the complexity of the structure is increased. Publication No. CN 213409076U discloses a gas-liquid cyclone separator, through adding a gas-liquid mixture medium inlet tube, with gaseous through with the communicating gas discharge pipe of the cyclone separation chamber in the cyclone cylinder discharge, liquid through with the communicating liquid discharge pipe of the cyclone separation chamber in the cyclone cylinder discharge, can with lower technical difficulty and lower cost design shaping, but this patent barrel is cylindrical, can not maintain good whirl intensity, leads to the gas-liquid separation efficiency not high. As can be seen, these gas-liquid separation devices proposed in the prior art have a complicated structure, are not flexible to operate, and have a small throughput. Secondly, the degree of rotational flow in the device is low, which results in low separation efficiency.
