Document Type and Number:
Japanese Patent JP2019120411
Kind Code:
A
Abstract:
To restrict piping corrosion in a partition wall penetration part.SOLUTION: A partition wall part penetration structure of a reaction vessel comprises: a partition wall that separates the inside and outside of the reaction vessel; at least one pipeline that communicates the inside with outside of the reaction vessel by penetrating the partition wall part; and a seal device provided on the outside of the reaction vessel that includes: a first seal member airtightly connected to the outer peripheral surface of the pipeline along an entire circumferential direction of the pipeline; a second seal member airtightly connected to an outer surface of the partition wall or an outer surface forming component provided on the outer surface of the partition wall over the entire circumferential direction of the pipe on the outside the outer circumferential surface of the pipeline; and an expansion member with one end airtightly connected to the first seal member and the other end disposed on the side opposite to the partition wall with respect ot the one end, the other end airtightly connected to the second seal member, to form the expansion member formed to absorb contraction in a pipe axial direction of the pipeline.SELECTED DRAWING: Figure 2
