This invention relates to an ultra-low sulfur pure biodiesel production equipment and method, belonging to the field of pure biodiesel production technology. It includes a modular support, with a pretreatment cylinder at the top of the modular support. The pretreatment cylinder has a feeding port at its top, and a cyclone centrifuge at its outlet. A feed pipe is fixedly connected to the outer wall of the cyclone centrifuge via a connecting pump. One end of the feed pipe is fixedly connected to a main dehydration and desulfurization tower.
