Reverse osmosis seawater desalination unit with replaceable high-pressure gas cylinders

Abstract

This invention provides a reverse osmosis seawater desalination device with a replaceable high-pressure gas cylinder, comprising a first container, a second container, a reverse osmosis membrane module, and a third container. The first container holds desalinated water. The second container holds seawater to be desalinated. The reverse osmosis membrane module is disposed at the bottom of the second container. The third container is disposed on the side of the second container opposite to the first container, and the third container can alternatively hold a high-pressure gas cylinder; the third container has a gas cylinder triggering module, which triggers the high-pressure gas cylinder to release high-pressure gas, thereby pressurizing the seawater in the second container, causing the seawater to pass through the reverse osmosis membrane module to form desalinated water, which then flows into the first container. This invention can reliably obtain desalinated water, improving its practicality in emergency or temporary water supply situations.

Claims

1. A reverse osmosis seawater desalination device with a replaceable high-pressure gas cylinder, comprising: a first container configured to hold desalinated water; a second container configured to hold seawater to be desalinated; a reverse osmosis membrane module disposed at the bottom of the second container and defining a fluid passage between the second container and the first container; and a third container disposed on one side of the second container opposite to the first container, the third container being configured to replaceably hold a high-pressure gas cylinder; the third container having a gas cylinder triggering module configured to trigger the high-pressure gas cylinder to release high-pressure gas, thereby pressurizing the seawater in the second container, causing the seawater to pass through the reverse osmosis membrane module to form desalinated water and flow into the first container.

2. The reverse osmosis seawater desalination device with replaceable high-pressure gas cylinder as described in claim 1, wherein, The gas cylinder triggering module includes a puncture member configured to puncture the neck of the high-pressure gas cylinder.

3. The reverse osmosis seawater desalination device with replaceable high-pressure gas cylinders as described in claim 2, wherein, The gas cylinder trigger module is a push-button type, and when the user applies force to the gas cylinder trigger module, the piercing element punctures the mouth of the high-pressure gas cylinder.

4. The reverse osmosis seawater desalination device with replaceable high-pressure gas cylinder as described in claim 2, wherein, The gas cylinder triggering module is configured to cause the puncture member to puncture the neck of the high-pressure gas cylinder when the third container is combined with the second container.

5. The reverse osmosis seawater desalination device with replaceable high-pressure gas cylinder as described in claim 1, wherein, The first container, the second container, and the third container are arranged sequentially along an axis and combined with each other.

6. The reverse osmosis seawater desalination device with replaceable high-pressure gas cylinders as described in claim 5, wherein, The first container, the second container, and the third container are assembled by a detachable connection structure secured by threads.

7. The reverse osmosis seawater desalination device with replaceable high-pressure gas cylinder as described in claim 1, wherein, This high-pressure gas cylinder is a disposable gas storage cylinder.
