The invention discloses a silicon ethane synthesis and filtration purification system. The silicon ethane synthesis and filtration purification system includes a silicon powder filtration treatment system, a silicon ethane purification system and a silicon ethane conversion system. a desilicomethane distillation tower, a first distillation tower, a second distillation tower and a third distillation tower of the silicon ethane purification system purify and separate silicon methane and silicon ethane through the difference of the molecular size and boiling point of silane, so achieve the effectof high-purity purification of the silicon ethane, micro nanoscale silicon powder generated by the above reaction is filtered by a filter group of the silicon powder filtration treatment system and regenerated by reverse blowing with nitrogen, and a dosing system adds a sodium hydroxide aqueous solution to the filter group, so residual micro nanoscale silicon powder and the sodium hydroxide aqueous solution react to form
