Abstract

In the process of biomass gasification, it is inevitable to produce by-products, among which the most important is the tar. With the continuous development of biomass gasification technology, a variety of tar removal methods have been developed. According to the principle of the process of tar removal, the two methods are physical and thermochemical. The venturi scrubber is physical wet decoking equipment, and it is an important part to improve the efficiency of removing tar. In order to improve efficiency of tar removal of venturi scrubber, the authors put forward square section venturi scrubber for removing the tar from biomass gas, modeled the venturi scrubber through the three-dimensional modeling software, carried out the numerical simulation, and obtained the velocity contours, pressure contours in several cases. The research indicates that the square tube has big pressure change. And the results of a venturi scrubber have a certain guiding role in engineering application.
