DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] See also Figure 1-4A distributor for a distillation tower includes a fixed frame 1 and a distribution slot 14. The fixed frame 1 is provided with a slot 8. A second block 9 is fixedly connected to the side end of the distribution slot 14. The second block 9 is engaged with the slot 8.
