Embodiment Construction
[0015] A gas supergravity dedusting or decoking process includes inputting gas and liquid into a supergravity dedusting or decoking device, and outputting after dedusting or decoking. The gas enters the inner cavity from the outer circumference of the rotating rotor 4 equipped with fillers or screens 5 in the supergravity dust removal or degumming device, flows from outside to inside through the fillers or screens 5, and flows out from the middle. The liquid flows in from the liquid inlet pipe 8, and is sprayed into the inner cavity of the rotating rotor 4 by the nozzle 9 in the center of the rotating rotor 4. Under centrifugal action, the gas is in the opposite direction from the inside to the outside, and passes through the filler or wire mesh 5 in the inner cavity of the rotor 4. Outflow from the bottom.
[0016] The gas and the liquid flow counter to each other under the high-speed rotation of the rotating rotor 4, and the liquid contacts the gas in the curved flow path at...

A fuel gas supergravity dedusting process comprises the step that a fuel gas and liquid are inputted into a dedusting device or a degumming device and outputted through the dedusting device. The dedusting device is a supergravity dedusting device or a degumming device which is provided with a rotary rotor; the fuel gas enters an inner cavity of the rotor through the outer circumference of a feed rotor, flows from the outside to the inside and flows out at the middle; the liquid flows in from a liquid inlet pipe, is sprayed into the inner cavity of the rotary rotor by a spray nozzle and flows out from the inside at the lower part, which is opposite to the flow of the fuel gas. The device comprises a motor and a casing which are arranged on a bracket, and the rotor which is arranged on the casing; a shaft at one end of the rotor is connected with a motor output shaft by a bearing arranged on the casing, the other end of the rotor is provided with a gas outlet pipe through the casing which is provided with a gas inlet and a water outlet, the liquid inlet pipe extends into the inner cavity of the rotor through the gas outlet pipe, the end part of the liquid inlet pipe is provided withthe spray nozzle, the liquid outlet is connected with a water seal tank, and a pump is connected with the water seal tank and the liquid inlet pipe. The dedusting process has the advantages of good separation effect, fast processing speed and high efficiency.
