摘要:
A two-stage granular moving-bed filter includes a gas inlet part, a gas outlet part, and a plurality of flow-corrective elements. The gas outlet part is disposed opposite to the gas inlet part, and the plurality of flow-corrective elements is disposed in a channel formed between the gas inlet part and gas outlet part. Meanwhile, a first granular material is provided to flow through a channel formed between the gas inlet part and the flow-corrective element in a state of mass flow, and a second granular material is provided to flow through a channel formed between the flow-corrective element and the gas outlet part. By means of having two different kinds of filter media moving through the channels between the gas inlet and outlet part, it is capable of performing two-stage filtering process after the raw gas flows therethrough, so as to improve the filtering effect of the gas.

A dynamically real-time adaptive trommel screen system is revealed. The dynamically adaptive trommel screen system includes a fixture, a trommel screen disposed on the fixture for screening a mixture into regenerated filter granules and screened residues, a structured duct for transporting the regenerated filter granules and an enclosure for collecting the screened residues, a tilt control member arranged on the fixture for adjusting the tilt angle of the trommel screen, and a feedback controller that controls the tilt control member according to the mass flow rate of the screened residues when the trommel screen operates so as to adjust the tilt angle of the trommel screen instantly and dynamically. By the feedback controller and the tilt control member, the tilt angle of the trommel screen is adjusted in a real-time and dynamic way so as to increase the screening efficiency. Moreover, the state of fractured filter granules is acquired from the feedback controller so that a certain amount of fresh filter granules can be refilled into the filter system for improving the filtration efficiency.

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.

A compact two-stage granular moving-bed apparatus comprises a vessel, a flow-corrective element, and a filter material supplying part. The vessel comprises a hollow interior, a gas outlet, a first media outlet and a second media outlet. The flow-corrective element divides the hollow interior into a first channel and a second channel. The filter material supplying part has a first provider for providing a first granular material flowing through the first channel and a second provider for providing a second granular material flowing through the second channel, wherein a vertical level of each first and second provider is adjustable so that a first flow path that an exhaust gas flows through the first granular material and a second flow path that the exhaust gas flow through the second granular material is respectively capable of being controlled.

A moving granular bed includes a filter granule channel, an inlet unit of gas, an outlet unit of gas, a first detecting unit and a feedback control unit. The inlet unit of gas is disposed at one side of the filter granule channel, and the dirty gas is fed into the filter granule channel through the inlet unit of gas. The inlet unit of gas has a first flow-guiding plate. The outlet unit of gas is disposed at the other side of the filter granule channel. The first detecting unit detects the gas velocity at the inlet unit of gas site. The feedback control unit is electrically connected with the first detecting unit, and controls the angle of the first flow-guiding plate and flow rate of filter granules according to a detecting result of the first detecting unit. A gas guiding system used in the moving granular bed is also disclosed. The moving granular bed and gas guiding system can make the dirty gas have different velocity or distribution while passing through the filter granule channel so as to improve the usage of the filter granules.

摘要:
A material is fabricated for capturing CO2 at mid-high temperature. The material is a layered material containing Ca, Al carbonates. A higher ratio of Ca to Al helps capturing CO2. The temperature for capturing CO2 is around 600° C. The material can even release CO2 at a high temperature. Thus, the material can process looping cycles of carbonation and decarbonization at a CO2 carbonation scale of 45% gCO2/g.
