Abstract

An adsorption structure unit prevents water leakage from an adsorption structure and improves the durability of the adsorption structure and the durability of the adsorption structure unit. An adsorption structure has a filter portion having a plurality of flow paths divided by a plurality of partition walls and a plugged portion shutting a feed water inflow or outflow end of the plurality of flow paths, a water-impermeable outer tube accommodating the filter portion, and a seal material blocking a gap between the filter portion and the outer tube in at least one end portion of the filter portion. An adsorption structure unit has the adsorption structure, a housing supplying feed water from one end of the adsorption structure, and discharging the feed water from the other end, and a ring member disposed between end portions on both sides of the outer tube and an inner surface of the housing.

Claims (26)

1. A method for manufacturing an adsorption structure, the method comprising:

a plugged portion formation process of loading a plugged portion at one end on either one end side or the other end side of a filter portion formed in a tubular shape and having multiple flow paths divided by multiple partition walls made of porous ceramic;

a loading process of loading the filter portion into a water-impermeable outer tube after the plugged portion formation process; and

a seal material disposition process of disposing a seal material between the outer tube and the filter portion, and

wherein the seal material is disposed by the seal material embedding between the outer tube and the filter portion after the loading process.

2. The method for manufacturing the adsorption structure according to claim 1 ,

wherein the seal material is disposed such that blocking is performed between the outer tube and the filter portion by the filter portion being loaded into the outer tube after the seal material is attached to at least one end of the filter portion where the plugged portion is formed.

3. A method for manufacturing an adsorption structure unit comprising:

a storage process of storing the adsorption structure manufactured by the manufacturing method according to claim 1 in a housing supplying feed water from one end and discharging the feed water from the other end; and

a disposition process of disposing first ring members between end portions on both sides of the outer tube and an inner surface of the housing.

4. The method for manufacturing the adsorption structure unit according to claim 3 , wherein

a first housing on a side where feed water is supplied and a second housing on a side where the treated water is discharged constitute the housing, and

a sealed structure is formed by the first housing and the second housing being fixed together via a second ring member different from the first ring members after the disposition process.

5. An adsorption structure produced by:

a plugged portion formation process of loading a plugged portion at one end on either one end side or the other end side of a filter portion formed in a tubular shape and having multiple flow paths divided by multiple partition walls made of porous ceramic;

a loading process of loading the filter portion into a water-impermeable outer tube after the plugged portion formation process; and

a seal material disposition process of disposing a seal material between the outer tube and the filter portion, and

wherein the seal material is disposed by the seal material embedding between the outer tube and the filter portion after the loading process.

6. The adsorption structure according to claim 5 ,

wherein the seal material is disposed such that blocking is performed between the outer tube and the filter portion by the filter portion being loaded into the outer tube after the seal material is attached to at least one end of the filter portion where the plugged portion is formed.

7. A method for manufacturing an adsorption structure unit comprising:

a storage process of storing the adsorption structure produced according to claim 5 in a housing supplying feed water from one end and discharging the feed water from the other end; and

a disposition process of disposing first ring members between end portions on both sides of the outer tube and an inner surface of the housing.

8. The method for manufacturing the adsorption structure unit according to claim 7 , wherein

a first housing on a side where feed water is supplied and a second housing on a side where the treated water is discharged constitute the housing, and

a sealed structure is formed by the first housing and the second housing being fixed together via a second ring member different from the first ring members after the disposition process.
