The present invention relates to a vertical reaction device comprising a cover sag preventing unit. More specifically, the vertical reaction device comprises a cover sag preventing unit which prevents the cover from sagging due to a mechanical fatigue caused by a load of the cover when the vertical reactor is repeatedly opened and closed. The vertical reaction device removes a coupling mismatch of a reaction unit and the cover, and prevents, in advance, an inaccuracy of an experimental condition in accordance with sagging; and having stability of an experimental condition during the experiment and laboratory research and development due to the same having economic efficiency as a rate of defect is reduced and a work speed increased. |
