Abstract

The present invention provides intermittent-bubbling equipment used while being immersed in a liquid. The intermittent-bubbling equipment includes a tubular casing vertically disposed; and a plurality of partition walls disposed substantially parallel to an axial direction in the casing, and configured to define a gas introducing chamber, a gas inducing chamber, and a gas discharging chamber. The gas introducing chamber and the gas inducing chamber communicate with each other at a top of the casing, and the gas inducing chamber and the gas discharging chamber communicate with each other at a bottom of the casing. An upper side of the gas introducing chamber and an upper side of the gas inducing chamber are closed by a lid plate, and a lower side of the gas inducing chamber and a lower side of the gas discharging chamber are closed by a bottom plate. A cross-sectional area of the gag introducing chamber may be greater than a cross-sectional area of the gas discharging chamber. An upper edge of a connecting hole between the gas inducing chamber and the gas discharging chamber may be substantially horizontal. A bottom plate that closes the gas inducing chamber and a bottom plate that closes the gas discharging chamber may be formed by a single flat member.

First claim

The invention claimed is:

1. Intermittent-bubbling equipment used while being immersed in a liquid, comprising:
a tubular casing vertically disposed; and a plurality of partition walls disposed substantially parallel to an axial direction in the casing, the partition walls being configured to define a gas introducing chamber, a gas inducing chamber, and a gas discharging chamber,
wherein the gas introducing chamber and the gas inducing chamber communicate with each other at a top of the casing, and the gas inducing chamber and the gas discharging chamber communicate with each other at a bottom of the casing; and
an upper side of the gas introducing chamber and an upper side of the gas inducing chamber are closed by a lid plate, and a lower side of the gas inducing chamber and a lower side of the gas discharging chamber are closed by a bottom plate,
wherein the casing has four external walls arranged in the shape of a rectangular tube;
the plurality of partition walls include four internal walls configured to define the gas discharging chamber in the shape of a rectangular column, and two parallel division walls configured to define the gas introducing chamber and the gas inducing chamber;
the internal walls are disposed substantially parallel to the opposite external walls;
the division walls extend continuously from respective two opposite ones of the four internal walls to one of the external walls; and
the internal wall interposed between the two internal walls has a connecting hole between the gas inducing chamber and the gas discharging chamber.

2. The intermittent-bubbling equipment according to claim 1 , wherein a cross-sectional area of the gas introducing chamber is greater than a cross-sectional area of the gas discharging chamber.

3. The intermittent-bubbling equipment according to claim 1 , wherein an upper edge of a connecting hole between the gas inducing chamber and the gas discharging chamber is formed to be substantially horizontal.

4. The intermittent-bubbling equipment according to claim 1 , wherein a bottom plate that closes the gas inducing chamber and a bottom plate that closes the gas discharging chamber are formed by a single flat member.

5. The intermittent-bubbling equipment according to claim 1 , wherein the gas discharging chamber is disposed in a center of the casing in plan view.

6. The intermittent-bubbling equipment according to claim 1 , wherein the intermittent-bubbling equipment is used for cleaning a filtration module having a plurality of filtration membranes.
