Description

Shipborne seawater desalination device

Technical Field

The utility model relates to a sea water desalination device, especially a shipborne sea water desalination device.

Background

The seawater is rich in high salt, so that the seawater cannot be directly drunk, if the seawater is drunk, a serious dehydration phenomenon can be generated, the body health of people is seriously influenced, and once the condition that the fresh water is insufficient occurs in the marine process, people on the ship cannot obtain enough drinking water resources, so that the marine survival time can be greatly shortened. Most of the traditional seawater desalination devices are bulky and need to be driven by electric energy, and once a ship encounters a sea disaster, an electric power system of the traditional seawater desalination device is often damaged, so that the traditional seawater desalination device cannot be used at all. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.

Disclosure of Invention

The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed, manual operation alright with the drive, and safe, reliable on-board sea water desalination device.

The technical solution of the utility model is that: a shipborne seawater desalination device is characterized in that: the seawater desalination device comprises a coarse filter 1, the coarse filter 1 is connected with a multimedia filter 3 through a pipeline with a first check valve 2, the multimedia filter 3 is connected by a line to a fine filter group comprising two fine filters 4 connected in series, the outlet end of the fine filter group is communicated with the piston cavity of the manual high-pressure reciprocating pump 6 through a pipeline with a second check valve 5, and the piston chamber of the manual high-pressure reciprocating pump 6 is also connected with the infiltration module through a pipeline with a third check valve 7 and a safety valve 8, and the orientation of the second check valve 5 and the third check valve 7 is opposite, the osmosis module comprises two reverse osmosis membrane separation filters 9 connected in parallel, and the pipelines at the two ends of each reverse osmosis membrane separation filter 9 are provided with stop valves 10, and the outlet end of the osmosis module is connected with a fresh water storage tank 11 through a pipeline.

Compared with the prior art, the utility model, have following advantage:

the shipborne seawater desalination device with the structure form is simple in structure, ingenious in design and reasonable in layout, and aims at various problems existing in the use process of the traditional seawater desalination device, a special structure is designed, seawater can be stored in a fresh water storage tank after being filtered in multiple stages, and precious fresh water resources can be obtained. The power part of the seawater desalination device is a manual high-pressure reciprocating pump, the seawater desalination device can be started without electric power, and fresh water resources can be still used under the condition that an electric power system is broken down. And two reverse osmosis membrane separation filters connected in parallel are arranged in the desalting device, so that the filtering effect is good, the two reverse osmosis membrane separation filters are mutually standby, and the reliability of the desalting device is ensured to the greatest extent. And the manufacturing process is simple, the manufacturing cost is low, so that the novel LED lamp has multiple advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1: a ship-borne seawater desalination device comprises a coarse filter 1, wherein the coarse filter 1 is connected with a multi-medium filter 3 through a pipeline with a first check valve 2, the multimedia filter 3 is connected by a line to a fine filter group comprising two fine filters 4 connected in series, the outlet end of the fine filter group is communicated with the piston cavity of the manual high-pressure reciprocating pump 6 through a pipeline with a second check valve 5, and the piston chamber of the manual high-pressure reciprocating pump 6 is also connected with the infiltration module through a pipeline with a third check valve 7 and a safety valve 8, and the orientation of the second check valve 5 and the third check valve 7 is opposite, the osmosis module comprises two reverse osmosis membrane separation filters 9 connected in parallel, and the pipelines at the two ends of each reverse osmosis membrane separation filter 9 are provided with stop valves 10, and the outlet end of the osmosis module is connected with a fresh water storage tank 11 through a pipeline.

The utility model discloses on-board sea water desalination device's of embodiment working process as follows: when seawater needs to be desalinated, firstly the coarse filter 1 is put into seawater, then the manual high-pressure reciprocating pump 6 is driven by hands to work, the piston of the manual high-pressure reciprocating pump 6 reciprocates in the piston cavity, when the handle of the pump body is pulled outwards, negative pressure is generated in the piston cavity, the negative pressure causes the seawater to enter the piston cavity after being filtered by the coarse filter 1, the multi-medium filter 3 and the two-stage fine filter 4, and when the handle of the pump body is pushed inwards, the second check valve 5 is closed, the third check valve 7 is opened, when the water enters the infiltration module again under the action of pressure, because the two reverse osmosis membrane separation filters 9 in the infiltration module are connected in parallel, therefore, only one of the reverse osmosis membrane separation filters is selected for filtering, the stop valve 10 on the other reverse osmosis membrane separation filter 9 is closed, and finally the desalinated water body is conveyed to the fresh water storage tank 11 for storage;

if the pressure in the pipeline is overlarge, the safety valve 8 is automatically opened and decompressed;

because the desalination device is provided with two reverse osmosis membrane separation filters 9 which are connected in parallel, the two reverse osmosis membrane separation filters can be used for each other, thereby greatly prolonging the service life of the device and ensuring the reliability of the device.
