Abstract: The instant disclosure relates to a granular bed filtration system with gas entrained recycling for thermal power plants to filter dust from the exhaust gas. The granular bed filtration system comprises a flow channel, a gas intake, a gas exhaust portion, a granular sieving unit, a vacuum, a cyclone separator and a pneumatic transporting device. The flow channels guide filtering media to filter the inlet gas, and then the filtered gas is exhausted through the gas exhaust outside of the granular bed filtration system. The granular sieving unit separates the filtering media and dust. The vacuum, pneumatic transporting device and cyclone separator repeatedly deliver the filtering media by gas-entrainment recycle.

Abstract: The present invention discloses a MOCVD gas diffusion system with gas inlet baffles. With the adoption of multiple detachable air inlet baffles under the MO gas (Metal Organic gas) inlet and the hydride gas inlet, the gas diffusion system can easily and effectively reduce the pre-reaction of the MO gas and the hydride gas near the gas inlets, prevent metal diffusions around the inlets and make the metal layer generated on the wafers on the wafer carrier be very even, the MO gas used is also massively reduced to save great cost. The MOCVD process with the diffusion system of the present invention thus has a great potential in application to productions of high-performance LED epitaxy.

Abstract: A gas distributor for a granular moving-bed filter comprises a distribution module, arranged inside a granular moving-bed filter. The distribution module comprises at least one flow-distributing curtain to be used for allowing a turbulent gas flow with dust mixed therein to flow therethrough, resulting that before the turbulent gas flow enters the granular moving-bed filter, the turbulent gas flow is transformed into a more uniformly distributed gas flow and the dust contained therein are partially filtered out.
