The reaction equipment comprises a slurry reactor, a heat remover and an axial flow pump, the slurry reactor is formed by combining a top part, a bottom part and a body, a first opening is formed in the lower half part of the slurry reactor, and a second opening is formed in the lower half part of the slurry reactor. The first opening is communicated with the axial flow pump through a pipeline; a second opening is formed in the upper half part of the slurry reactor and is communicated with the top of the heat remover through a pipeline; and the heat remover bottom is communicated with the axial flow pump. Various polyethylene products can be produced by adopting one set of reaction equipment, the combination of the reaction equipment is flexible, the slurry reactors at different opening positions can be combined for use, the combined efficient utilization of the equipment is enhanced, and resources are saved. 本发明公开了一种淤浆法聚乙烯的反应设备及制备淤浆法聚乙烯的方法，所述反应设备包括淤浆反应器、撤热器和轴流泵，所述淤浆反应器由一个顶部、一个底部和一个本体三部分组合而成，所述淤浆反应器下半部设置第一开口，
