Absorption rotor, rotor element, method of manufacturing absorption rotor, and method of manufacturing rotor element

A rotor element provided in an absorption rotor which is provided in a flow passage of a gas containing a substance to be absorbed, the absorption rotor through which the gas passes while the absorption rotor is rotated about a rotation axis, the rotor element comprising:

• an absorption member accommodated in a space which is surrounded by plural plate members extending in a radial manner from a circumference of the rotation axis and a tubular outer edge member coupling end portions of the plural plate members, the absorption member that absorbs the substance to be absorbed when the gas passes through;
• and
• a drop-off prevention member respectively fixed to one plate member of the plural plate members and the absorption member, the drop-off prevention member that prevents the absorption member from dropping off the plate member,
• wherein
• the drop-off prevention member is arranged between the absorption member and the plate member, and between a surface from which the gas flows into the absorption member and a surface from which the gas flows out of the absorption member,
• the drop-off prevention member has an embedded portion embedded in the absorption member, and an exposed portion exposed from the absorption member,
• the embedded portion is fixed to the absorption member, and the exposed portion is fixed to the plate member,
• the plate member has a holding portion that holds an inner end portion of the exposed portion, the inner end portion being an end portion of the exposed portion of the drop-off prevention member on the side close to the rotation axis, and
• the holding portion is provided on a surface of the plate member that is adjacent to the rotation axis, and protrudes from the surface of the plate member.

A method of manufacturing an absorption rotor including plural plate members extending in a radial manner from a circumference of a rotation axis, a tubular outer edge member coupling end portions of the plural plate members, an absorption member accommodated in a space which is surrounded by the plural plate members and the tubular outer edge member, the absorption member that absorbs a substance to be absorbed when a gas containing the substance to be absorbed passes through, and a drop-off prevention member respectively fixed to one plate member of the plural plate members and the absorption member, the drop-off prevention member that prevents the absorption member from dropping off the plate member,

• the method comprising the step of:
• arranging the drop-off prevention member between the absorption member and the plate member, and between a surface from which the gas flows into the absorption member and a surface from which the gas flows out of the absorption member, wherein
• the drop-off prevention member has an embedded portion embedded in the absorption member, and an exposed portion exposed from the absorption member,
• the embedded portion is fixed to the absorption member, and the exposed portion is fixed to the plate member,
