Embodiment Construction

[0056] Hereinafter, some embodiments of the present invention will be described with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, etc. of components described as embodiments or shown in the drawings are not intended to limit the scope of the present invention, but are merely illustrative examples.

[0057] For example, expressions such as "in a certain direction", "along a certain direction", "parallel", "orthogonal", "center", "concentric" or "coaxial" indicate relative or absolute configurations, not only strictly Such an arrangement is shown, and it also shows a state of being relatively displaced by an angle and a distance to the extent that a tolerance or the same function can be obtained.

[0058] For example, expressions such as "same", "equal" and "homogeneous" that indicate the state of equality of things not only strictly represent the state of equality, but also represent the state of tolerance or the degree of differ...

Abstract

A method for detaching a catalyst unit according to one embodiment involves detaching a catalyst unit that is accommodated in a reactor casing of a catalytic reactor, wherein the method comprises a step in which, when the catalyst unit is detached from the reactor casing, which is configured so as to assume a cylindrical shape extending in the vertical direction and so that a gas at a gauge pressure of 0.2 MPa or higher is introduced into the interior of the reactor casing, the catalyst unit is passed through a gas flow passage opening that is formed in the top of the reaction casing.

Description

technical field [0001] The invention relates to a method for disassembling and assembling a catalyst unit and a catalytic reactor. Background technique [0002] For example, in a denitrification device installed in a thermal power plant or the like, a catalyst is accommodated in a reactor of the denitrification device (see Patent Document 1). [0003] In addition, among the sulfur compounds contained in the synthesis gas, it is used to convert COS (carbonyl sulfide) into H 2 A catalyst is accommodated in the S (hydrogen sulfide) reactor (see Patent Document 2). [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent No. 4435964 [0007] Patent Document 2: Japanese Patent No. 3764568 [0008] In the denitrification device described in Patent Document 1 above, a catalyst having a honeycomb structure in which a plurality of flow paths extending in the axial direction are formed is used. [0009] The denitrification device descri...
