Embodiment 1

[0039] like Figure 1-2 In the example shown, a primary partition 3 is provided along the length direction of the hull, which can divide the cabin into several long and narrow strip-shaped spaces extending along the length direction of the hull.

[0040] The filtering drainage facility of the present invention may be a geotextile laid on the bottom of the bilge and matching drainage pipes. The water after desalination of sea sand can pass through the fiber gap of the geotextile and be discharged from the sea sand body, and the geotextile will retain the desalinated sea sand. Moisture passing through the geotextile is drained by the drainage pipe.

[0041] The filtration and drainage facility of the present invention can also be an anti-filter layer laid on the bilge and a drainage pipe matched therewith, and the water after desalination of sea sand passes through the anti-filter layer and is discharged from the drainage pipe. The reverse filter layer is a graded gravel layer...

Embodiment 2

[0045] like Figure 3-4 In this example shown, a primary partition 3 is arranged along the length direction of the hull, and a secondary partition 4 is also provided along the width direction of the hull. The primary partition and the secondary partition are fixedly connected and arranged vertically. Several block spaces are formed.

[0046] The present invention can properly determine the quantity of the primary partition and the secondary partition according to the actual situation of the hull and the transportation needs, and divide the cabin into strip-shaped or L-shaped or #-shaped partitioned areas.

[0047]When transporting sea sand, the loaded sea sand is relatively separated and packed in different areas. During the subsequent sea sand desalination treatment, fresh water is injected into each divided area, and the sea sand in different areas is desalinated. According to the needs or actual loading characteristics, more fresh water can be properly added to the divided...

Embodiment 3

[0058] In the method of the present invention, adding fresh water, washing and desalination and draining can be carried out simultaneously, and fresh water is preferably injected into the cabin from the top of the cabin, and the injection amount of fresh water should be less than 100 times of the sea sand volume. When the fresh water is injected, the fresh water seeps downward from the sea sand body, fills the gaps between the sand particles, and desalinizes the sea sand. The water after desalination of the sea sand that seeps to the bottom of the cabin is discharged through the filter drainage facility, and the sea sand is also discharged at the same time. Water originally present in the body. The desalinated water is discharged in time, which can avoid a large amount of water accumulation in the cabin, reduce the load bearing of the hull, and is conducive to safe operation.

Abstract

The invention provides a ship for desalting sea sand. A filtering and draining device is arranged at the bottom of a cabin. The invention further provides a method for desalting sea sand on the ship. The method comprises the following steps: (1) filling sand: sea sand needing to be desalted is sent to the cabin for storing sea sand, and the filtering and draining device is arranged at the bottom of the cabin; (2) filling fresh water: fresh water is filled in a cabin body, and is filled from the upper part of the cabin to the interior of the cabin body, or is filled in the reverse direction from the filtering and draining device at the bottom of the cabin; (3) washing and desalting: fresh water seeps downwards from sea sand or seeps upwards to fill the gap among sand grains and desalt sea sand; and (4) draining: the draining device at the bottom of the cabin drains water after desalting sea sand and original water contained in sea sand. The ship and the method realize the purpose of desalting sea sand or brackish sand on the ship, and have the advantages of water saving, low operation cost, and small investment, and chloridion indexes of sea sand or brackish sand completely reach the national standard for sand for building.

Description

technical field [0001] The invention relates to the field of sea sand desalination, in particular to a ship for desalination of sea sand and a method for desalination of sea sand or semi-salt sand on the ship. Background technique [0002] With the rapid development of the economy, new resources are continuously developed and utilized. Sea sand or semi-fresh salty sand (this kind of sand is located in the estuary of rivers. Since these areas are occupied by fresh water during ebb tide, sea water can seep in during high tide, and are affected by Due to this effect, the chloride ion content of the sand in this area is higher than that of river sand, but lower than that of sea sand) as a new building material and has been widely used in the construction field. Sea sand or semi-fresh salty sand carries a large amount of chloride ions, which will corrode steel bars. Direct use of sea sand in construction will cause building safety hazards. Therefore, it is necessary to remove the...
