Abstract

A condenser includes: a vessel ( 11 ) into which steam (S) is introduced in a first horizontal direction (X); cooling tube groups ( 21, 22, 23, 24 ) each formed long in the first horizontal direction (X) inside the vessel ( 11 ) by arranging a plurality of cooling tubes ( 31 ) in a second horizontal direction (Y) in parallel; a hollow portion ( 32 ) formed in the first horizontal direction (X) inside each of the cooling tube groups ( 21, 22, 23, 24 ); a non-condensed gas discharge unit ( 33 ) arranged in the second horizontal direction (Y) at a downstream end portion in a flow direction of the steam (S) in each of the cooling tube groups ( 21, 22, 23, 24 ), and including opening portions ( 34 ) on the hollow portion ( 32 ) side; and a partition member ( 35 ) opened to the hollow portion ( 32 ) side from the opening portion ( 34 ) side of the non-condensed gas discharge unit ( 33 ).

First claim

1 . A condenser including:
a vessel into which steam is introduced in a first horizontal direction; a cooling tube group formed long in the first horizontal direction inside the vessel by arranging a plurality of cooling tubes in a second horizontal direction intersecting with the first horizontal direction; a hollow portion formed in the first horizontal direction inside the cooling tube group; a non-condensed gas discharge unit arranged in the second horizontal direction at a downstream end portion in a flow direction of the steam in the cooling tube group, and including an opening portion on the hollow portion side; and a partition member opened to the hollow portion side from the opening portion side of the non-condensed gas discharge unit.

2 . The condenser according to claim 1 , wherein the non-condensed gas discharge unit has a hollow shape and is arranged such that surfaces other than one surface are surrounded by the cooling tube group and the one surface faces a steam passage and also faces an inner wall surface of the vessel.

3 . The condenser according to claim 1 , wherein
the partition member includes: an upper partition plate arranged in the second horizontal direction and having a proximal end portion connected to an upper portion of the non-condensed gas discharge unit; and a lower partition plate arranged in the second horizontal direction and having a proximal end portion connected to a lower portion of the non-condensed gas discharge unit, and the upper partition plate and the lower partition plate have respective distal end portions in communication with the hollow portion.

4 . The condenser according to claim 3 , wherein the upper partition plate extends upward at a predetermined inclination angle toward the hollow portion side.

5 . The condenser according to claim 3 , wherein the upper partition plate and the lower partition plate are arranged such that a distance between the upper partition plate and the lower partition plate becomes larger toward the hollow portion side.

6 . The condenser according to claim 3 , wherein a baffle plate is arranged at a position separated from the non-condensed gas discharge unit to the hollow portion side by a predetermined distance in a manner facing the opening portion and keeping a predetermined space from the upper partition plate and the lower partition plate.

7 . The condenser according to claim 3 , wherein an upper gas flow passage is provided along an upper surface of the upper partition plate, a lower gas flow passage is provided along a lower surface of the lower partition plate, and the upper gas flow passage and the lower gas flow passage are in communication with the hollow portion.

8 . The condenser according to claim 3 , wherein an upper gas flow passage is provided along an upper surface of the upper partition plate, a lower gas flow passage is provided along a lower surface of the lower partition plate, and the cooling tubes are arranged in the space between the upper and lower gas flow passages and the hollow portion.

9 . The condenser according to claim 7 , wherein the upper partition plate and the lower partition plate have distal end portions provided with an upper guide portion and a lower guide portion respectively which are bent in directions approaching to each other.

10 . The condenser according to claim 1 , wherein a plurality of saucers is arranged in the first horizontal direction at predetermined intervals at a lower portion of the hollow portion.

11 . The condenser according to claim 1 , wherein the cooling tube group, the hollow portion, the non-condensed gas discharge unit, and the partition member are provided in a vertically line-symmetric shape.

12 . The condenser according to claim 1 , wherein the cooling tube group is divided into an upper cooling tube subgroup and a lower cooling tube subgroup relative to the hollow portion, and a thickness in the vertical direction of the upper cooling tube subgroup is set thicker than a thickness in the vertical direction of the lower cooling tube subgroup.

13 . The condenser according to claim 1 , wherein the non-condensed gas discharge unit has a hollow shape and is arranged in a manner projecting from the cooling tube group, facing a steam passage, and also facing an inner wall surface of the vessel.

14 . The condenser according to claim 1 , wherein the hollow portion is gradually tapered toward an upstream side in a flow direction of steam in the cooling tube group.

15 . The condenser according to claim 2 , wherein
the partition member includes: an upper partition plate arranged in the second horizontal direction and having a proximal end portion connected to an upper portion of the non-condensed gas discharge unit; and a lower partition plate arranged in the second horizontal direction and having a proximal end portion connected to a lower portion of the non-condensed gas discharge unit, and the upper partition plate and the lower partition plate have respective distal end portions in communication with the hollow portion.

16 . The condenser according to claim 4 , wherein the upper partition plate and the lower partition plate are arranged such that a distance between the upper partition plate and the lower partition plate becomes larger toward the hollow portion side.

17 . The condenser according to claim 4 , wherein a baffle plate is arranged at a position separated from the non-condensed gas discharge unit to the hollow portion side by a predetermined distance in a manner facing the opening portion and keeping a predetermined space from the upper partition plate and the lower partition plate.

18 . The condenser according to claim 5 , wherein a baffle plate is arranged at a position separated from the non-condensed gas discharge unit to the hollow portion side by a predetermined distance in a manner facing the opening portion and keeping a predetermined space from the upper partition plate and the lower partition plate.

19 . The condenser according to claim 4 , wherein an upper gas flow passage is provided along an upper surface of the upper partition plate, a lower gas flow passage is provided along a lower surface of the lower partition plate, and the upper gas flow passage and the lower gas flow passage are in communication with the hollow portion.

20 . The condenser according to claim 5 , wherein an upper gas flow passage is provided along an upper surface of the upper partition plate, a lower gas flow passage is provided along a lower surface of the lower partition plate, and the upper gas flow passage and the lower gas flow passage are in communication with the hollow portion.
