Segmented supporting structure applied to large nuclear power deaerator

The invention discloses a segmented supporting structure applied to a nuclear power large-scale deaerator, and belongs to the technical field of large-scale deaerator assembly. The problem that an existing barrel supporting device is not suitable for a large-size barrel is solved. A plurality of first positioning holes in each positioning hole set are distributed in an annular matrix mode with the circle center of the center plate as the reference, a plurality of second positioning holes are formed in one end of each supporting steel channel, a supporting end plate is fixedly installed at the other end of each supporting steel channel, and a plurality of pre-welding plates are welded in the deaerator barrel in the circumferential direction of the deaerator barrel. And each supporting end plate is fixedly connected with the corresponding pre-welding plate through a screw. The overall size of the segmented supporting structure is adjusted by adjusting the position of the supporting channel steel in the radial d
