224 results about "Cyclone" patented technology

In meteorology, a cyclone is a large scale air mass that rotates around a strong center of low atmospheric pressure. Cyclones are characterized by inward spiraling winds that rotate about a zone of low pressure. The largest low-pressure systems are polar vortices and extratropical cyclones of the largest scale (the synoptic scale). Warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale. Mesocyclones, tornadoes, and dust devils lie within smaller mesoscale. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the tropical upper tropospheric trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars, Jupiter, and Neptune. Cyclogenesis is the process of cyclone formation and intensification. Extratropical cyclones begin as waves in large regions of enhanced mid-latitude temperature contrasts called baroclinic zones. These zones contract and form weather fronts as the cyclonic circulation closes and intensifies. Later in their life cycle, extratropical cyclones occlude as cold air masses undercut the warmer air and become cold core systems. A cyclone's track is guided over the course of its 2 to 6 day life cycle by the steering flow of the subtropical jet stream.

The utility model relates to the technical field of gas-solid separation, in particular to a double-inlet multi-stage matrix type cyclone separator capable of realizing efficient gas-solid separation, which comprises a primary cyclone separator, the device further comprises a second-stage cyclone separator and a third-stage cyclone separator. The two symmetrical inlets are formed in the first-stage cyclone separator, flow field asymmetry caused by an inlet structure can be effectively solved, the spiral guide vanes are arranged at the inlet of the second-stage cyclone separator, the pressure drop of the system is reduced by guiding airflow, and the separation efficiency is further improved. And a multi-inlet structure is arranged on the three-stage cyclone separator, so that the pressure drop of the cyclone separator can be effectively reduced through the multi-inlet structure, the separation efficiency of the cyclone separator is improved, the stability of an internal flow field of the cyclone separator is greatly improved, and the gas-solid separation performance is excellent. The cyclone separator is suitable for efficient dust removal and particle recovery under high-density and high-pressure working conditions of petrochemical engineering, coal chemical engineering and the like, the pressure drop of the cyclone separator is effectively reduced, and the separation efficiency is improved.
