Abstract

The invention provides a synthesis gas washer and a synthesis gas washing system. The synthesis gas washer comprises a synthesis gas pipe and a grey water pipe, wherein a water spraying nozzle of the grey water pipe is communicated with the synthesis gas pipe, a sleeve is arranged in the synthesis gas pipe, the water spraying nozzle of the grey water pipe is opposite to the gas inlet of the sleeve, and a swirler is arranged at the position, close to the water spraying nozzle of the grey water pipe, of the grey water pipe. The swirler is arranged at the position, close to the water spraying nozzle of the grey water pipe, of the grey water pipe, initial atomization can be conducted on wash water through the swirler, the contact areas between the dust particles and atomized droplets are enlarged, the atomized droplets can rapidly wrap the dust particles and can be sprayed out at a high speed, and therefore particle separation and gas purification can be better achieved through the synthesis gas washer.

Description

technical field [0001] The invention relates to the field of coal chemical industry, in particular to a mixer washing device and a mixer washing system for dusty gas. Background technique [0002] The coal gasification process uses oxygen (air, oxygen-enriched or industrial pure oxygen) and water vapor as the gasification agent to convert the combustible part of coal or coal char into combustible gas through chemical reaction under high temperature and pressure. Since the gasification reactor is a gas-liquid-solid three-phase system, a large number of fly ash particles are carried in the syngas after chilling or radiation waste pot cooling. The purification and particle separation of syngas are the prerequisites for further processing of syngas. [0003] In the process of purification and particle separation of syngas, Venturi scrubber (also known as Venturi dust collector), as a syngas separation device integrating atomization, condensation and demisting functions, plays a...
