Abstract

Venturi scrubber is usually used to purify biomass gas. In order to improve efficiency of biomass gas purification of venturi scrubber, a test apparatus of the square section venturi scrubber was established to purify biomass gas. On the basis of analysis of the surge flow and the model selection of the standard model, and suing CFD software, the inner flow field of biomass gas purification of the square section venturi scrubber was simulated, the internal pressure features and the speed features of the square section venturi scrubber were obtained. Compared to circular section venturi scrubber, the square section venturi scrubber has big turbulence intensity in the throat, and there will be flow back at the end of the pipe, which makes the tar particles inside the biomass gas better adsorption, so as to achieve better effect of decoking.
