The invention relates to the technical field of seawater desalination, and particularly provides an effect body evaporator, a low-temperature multi-effect distillation seawater desalination system and a low-temperature multi-effect distillation seawater desalination method. When the steam extraction circulating unit extracts steam, the opening degree of a flexible communicating hole in the double-flow-channel heat exchange pipe is gradually increased, so that most of steam entering the heat exchange pipe flows to an intermediate-effect evaporator through a main flow channel; and under the condition that the flow of the steam received by the first-effect evaporator is reduced, the flexible communication hole is gradually reduced, so that most of the steam entering the heat exchange pipe is subjected to heat exchange through the auxiliary flow channel under the action of the steam extraction pressure difference, and therefore, efficient utilization and heat energy recovery of the steam in the low-temperature multi-effect distillation seawater desalination system are realized, and the energy consumption is reduced. And meanwhile, scaling of the outer wall of the heat exchange tube of the first-effect evaporator due to the fact that the heat exchange tube bears the relatively unstable steam change condition can be effectively prevented, and scaling and cleaning difficulty of the first-effect heat exchange tube bundle are greatly reduced.
