Mujumdar (1988) devised two methods using vibration technic of fluidization for fluidizing hot-sensitive and paste-like materials. Yoshihide et al. (2003) studied the effec... | https://en.wikipedia.org/wiki?curid=40798796 |
Vibratory fluidized bed This will then cause the drying rate to increase because of the increase in gas temperature which causes the gas humidity to decrease. The effects of particle size were modelled as well. It was found that. Larger particle need longer time to dry to reach the same moisture content due to increase... | https://en.wikipedia.org/wiki?curid=40798796 |
Vibratory fluidized bed This is because a potential customer would want to know the requirements of the process. Therefore, individual energy consumption for each part of the vibrating fluidized bed should be taken into account. The same can be said about the vibrating fluidized bed when we look at it from an economica... | https://en.wikipedia.org/wiki?curid=40798796 |
Vibratory fluidized bed By feeding gas tangentially into the cyclone body, high speed rotating flow established a centrifugal force and creates vortexes of particles. Different cyclones have different specification and characteristics. Generally, larger than 100 μm or denser particles, which have more inertia, are push... | https://en.wikipedia.org/wiki?curid=40798796 |
Vibratory fluidized bed Compared to baghouse, a scrubber injects a dry reagent or slurry into dirty feed gas, via the contact of target materials to remove pollution. Depending on the properties of the compound, different pollutants correspond to different scrubbing techniques and reagents. For ash and dust, water can ... | https://en.wikipedia.org/wiki?curid=40798796 |
