The production equipment of high-purity isobutylene according to claim 7, characterized in that: The filtrate module comprises a purification filter element (71) which is arranged on the inner side of the purification chamber (22) and fixedly connected to the liquid guide cylinder (53); a spiral brush sheet (72) is installed on the inner guide shaft (33) at a position corresponding to the inner side of the purification filter element (71); the spiral brush sheet (72) is fitted with the purification filter element (71); a drain valve (73) is installed at the bottom end of the purification tank (200); the drain valve (73) is slidably connected to the inner cavity of the purification filter element (71); a repurification pipe (74) is connected to the bottom of the purification chamber (22); a pump body (75) is installed at the lower part of the distillation tower (100); the repurification pipe (74) is connected to the distillation chamber (11) through the pump body (75); and a plurality of groups of jet holes (76) distributed in a circular array and connected to the lower flow channel (55) are provided on the inner guide shaft (33) at a position corresponding to the inner side of the purification chamber (22).

9. The method for producing high-purity isobutylene according to any one of claims 1 to 8, characterized in that: The following steps are involved: SS01. It is preset that before isobutylene is produced, a sufficient amount of isobutylene reaction stock solution is injected into the distillation chamber (11). After the isobutylene reaction stock solution is injected, the heating jacket (12) heats the isobutylene reaction stock solution in the distillation chamber (11) to a boiling state; SS02, distillation purification, after step SS01, the motor (34) continuously outputs the rotation speed. After the motor (34) outputs the rotation speed, the vacuum pump (24) and the back-clearing pump (25) continue to work. When the vacuum pump (24) and the back-clearing pump (25) are working, the reciprocating vibration setting of the vibration frame (31) enables the vacuum pump (24) and the back-clearing pump (25) to be alternately connected to the purification chamber (22). The distillation gas generated in the distillation chamber (11) is condensed through the spiral condensation coil (54), and the condensed condensate enters the purification filter element (71) for filtration. The filtrate filtered by the purification filter element (71) flows back to the distillation chamber (11), and then circulated purification is carried out.
