Description

A kind of small reverse osmosis water purifier for offshore operation

Technical field

The utility model belongs to Miniature seawater desalination device field, is specifically related to a kind of small reverse osmosis water purifier for offshore operation.

Background technology

Seawater, due to too high in salinity, is not suitable for the mankind and directly drinks.Seawater to be converted into the fresh water that can directly drink, must use desalination technology.At present, built or mainly with distillation method and reverse osmosis method, be main at the sea water desaltination equipment of building, wherein in the majority with large-scale seawater equipment.But for offshore operation such as fishing row, fishing boats, large-scale sea water desalting equipment no doubt can not meet its demand to Freshwater resources.

Existing Miniature seawater desalination device, controls more complicated, and operational process is unstable, and is subject to environmental limit and should not uses on a large scale, and equipment energy consumption is higher in the situation that of the equal output value, and cost is wayward.

Summary of the invention

The purpose of this utility model is to provide a kind of small reverse osmosis water purifier for offshore operation, especially be applicable to being applied to the offshore operation such as fishing row, fishing boat, can also, as the nucleus equipment of the tap water such as island, oil field and coastal neighboring area and domestic water, also can be used as the water treating equipment of the industries such as food, beverage, chemical industry, medicine, semi-conductor, electronics.

For achieving the above object, the utility model is achieved by following technical solution:

For a small reverse osmosis water purifier for offshore operation, comprise more medium filter, cartridge filter, accurate filter, sea-water pump and seawater reverse osmosis membrane system; Described more medium filter, cartridge filter, accurate filter, sea-water pump and seawater reverse osmosis membrane system are connected by pipeline in turn; Described more medium filter is provided with seawater water-in.

Cartridge filter described in the utility model is different from the filter core aperture of accurate filter.The filter core of cartridge filter described in the utility model is slightly larger than the filter core of accurate filter, object is to filter as the first step security personnel, removal small-particle multimedium material and impurity that after more medium filter filters, seawater carries out, then seawater enters the further intensive filtration of accurate filter that filter core is less again, thereby guarantee carrying out smoothly of follow-up reverse osmosis membrane filtration, when guaranteeing effluent characteristics, extend the work-ing life of reverse osmosis membrane.

Described seawater reverse osmosis membrane system is comprised of No. 1 parts of reverse osmosis membrane and No. 2 parts of reverse osmosis membrane, and No. 1 parts of described reverse osmosis membrane and No. 2 parts of reverse osmosis membrane are respectively two reverse osmosis membrane filtration pipes.Reverse osmosis membrane is a kind of semi-permeable membranes, and depended on pressure drives the effect that reaches reverse osmosis, can make the small molecules such as water molecules see through film, and ion is trapped, thereby reach separated concentrated seawater and pure water.

No. 1, described reverse osmosis membrane and No. 2 parts of reverse osmosis membrane are equipped with pure water outlet and dense water out.

The pure water outlet of No. 1 parts of described reverse osmosis membrane and the pure water outlet of No. 2 parts of reverse osmosis membrane are communicated with merges into a pure water outlet, i.e. total pure water outlet.Outside the system of fresh water by this outlet bleeder.No. 2 parts of the dense water out of No. 1 parts of described reverse osmosis membrane and reverse osmosis membrane are connected.

Linking relationship and the working process of No. 1 parts of described reverse osmosis membrane and No. 2 parts of reverse osmosis membrane are:

Seawater after multimedium, security personnel, secondary filter are processed is introduced No. 1 pipe of reverse osmosis by sea-water pump, and seawater is separated into dense water and fresh water after No. 1 parts of reverse osmosis.Fresh water is flowed out by pure water exit, and concentrated stream enters No. 2 parts of reverse osmosis and proceeds reverse-osmosis treated.In like manner, seawater is further separated into more concentrated seawater and fresh water in No. 2 parts of reverse osmosis again, and fresh water flows out from No. 2 parts pure water outlets of reverse osmosis, and concentrated seawater flows out from dense water out.

Working process of the present utility model is: first seawater is imported to more medium filter, then seawater enters cartridge filter, accurate filter, finally by sea-water pump, seawater is imported to seawater reverse osmosis membrane system and complete sea water desaltination, the water of having desalinated flows out from pure water outlet, and remaining concentrated seawater is discharged from dense water out.

The utlity model has following beneficial effect:

The seawater desalination reverse osmosis device that the utility model provides adopts advanced reverse osmosis technology to purify to seawater, in conjunction with well-designed filtration and adsorption system, can effectively remove the material that in water, each bacterioid, virus, pesticide residue, heavy metal ion etc. are harmful to health, more can remove the carcinogenic pathogenic things such as trichloromethane that conventional means cannot remove, fluorine.Device installation and debugging of the present utility model are simultaneously convenient, simple to operate, maintenance and repair is simple, have great application prospect.
