Hypergravity dust-removing or decoking technique for gas and device

Abstract

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.

Description

1. Technical field [0001] The invention relates to gas dedusting and decoking process and equipment for power generation, in particular to a gas supergravity dedusting or decoking process and device 2. Background technology [0002] At present, the dust removal and decoking process of power generation gas generally adopts filtration technology and static tower structure equipment, which can remove part of the dust and colloid suspended in the gas, but this dust removal, decoking process and equipment have the following shortcomings or deficiencies : ① backward technology, poor dust removal and decoking effect; ② huge equipment, large floor area, high input cost; ③ high operating cost, short maintenance cycle; ④ poor separation effect, slow speed and low efficiency. 3. Contents of the invention [0003] The purpose of the present invention is to provide a gas supergravity dedusting or decoking process, which uses the supergravity generated by the supergravity dedusting or d...
