Mechanical sealed balance tank auxiliary structure applied to reactor

The invention relates to the field of reactor sealing technology, and especially relates to a mechanical sealed balance tank auxiliary structure applied to a reactor. The auxiliary structure comprises a reactor (1) and a balance tank (2). The balance tank (2) is communicated with the reactor body (10) of the reactor (1) through an impulse pipe (3). The impulse pipe (3) is communicated with the feed pipe of the reactor (1) at the same time. The balance tank (2) has a cavity (20). The cavity (20) is communicated with the sealing liquid inlet (401) of a sealing liquid cavity (40) through a first pipeline (51) and is communicated with the sealing liquid outlet (402) of the sealing liquid cavity (40) through a second pipeline, and the cavity (20), the first pipeline (51), the sealing liquid cavity (40), and the second pipeline form a sealing liquid loop. Pressure is applied on the feed pipe of the reactor and gas phase in the reactor body (10) at the same time to make the pressure in the impulse pipe (3) be slight
