Abstract
A process for desalinizing sea water in deep sea and its extracting method are disclosed. The pressure difference between atmosphere pressure at sea level and sea water column pressure in deep sea is used to make sea water penetrate through filter-purifying layer and desalininzing layer of desalinizing system. The purified and desalinized water is input to the fresh water pipe and container in fresh water storage-delivery control system, and then pumped up to sea surface for pouring it in containers. Its advantages are no pollution and high desalinizing efficiency.
Description
The present invention relates to sea water desaltination and extraction technique, the sea water desaltination and the abstracting method in zone, particularly a kind of deep-sea.
Recently the contaminated degree of seawater is serious all the more, particularly its bacterium, organic compound, mineral oils, suspended particulate etc. have influenced the seawater hygienic quality in the seawater on greater coasting area and top layer, be unfavorable for that the mankind get its desalination and drink, hindered the normal growth of famous and precious fishes and shrimps to grow, and desalinating cost increases in desalting process, and the dope discharging has caused the environmental pollution in land and coastal waters.
And deep sea water is nutritious and lack contaminated, deep sea water is meant off sea seawater below 200 meters of benthos, the depths, sea is difficult to see sunlight, the few bacterium of low temperature, thereby the organism decomposition rate exceeds resultant velocity greatly, in the process that organism promptly decomposes in a large number, produced abundant nitrogenous, phosphorous nutrition, take or desalinate the bathypelagic salt water supply mankind and be used as heath food, and production novel food product, bring up famous and precious fishes and shrimps, preparation cosmetics etc. all have great economic benefit and development prospect.
Existingly extract the technology that the shallow sea seawater is desalinated on land, the one, extract contaminated seawater surface layer, extraction be contaminated water source; The 2nd, in desalting process, need pressurization to separate, polluted environment thus.
The purpose of this invention is to provide a kind of improved sea water in deep sea desalination and abstracting method, it can desalinate and extract not contaminated seawater in the deep-sea, and the course of processing is not polluted.
Technical solution of the present invention is as follows:
A kind of sea water in deep sea desalination and abstracting method, utilize the pressure reduction of barometric point and deep sea water column pressure on the sea level, make deep-sea water penetrate filtration, purification layer and desalination layer in the desalination system, seawater through purify, in fresh water communicating pipe and water container in the desalination back input fresh water storage transport control system, promote by the water pump supercharging, by hydraulic pipe output sea can.
Adopt method of the present invention to desalinate exploitation to deep sea water, deep sea water promptly can directly be taken after desalination, being drawn into the land, also can add in various food, the beverage supplement as nutritive health-care to.The present invention does not pollute in the course of processing, and the desalination rate is higher.
Below in conjunction with accompanying drawing embodiments of the invention are elaborated.
Fig. 1 is a single-stage desalination system synoptic diagram.
Fig. 2 is a two-stage tandem desalination system synoptic diagram.
Fig. 3 is a plural serial stage desalination system synoptic diagram.
Referring to Fig. 1, as desalination of the sea water in deep sea of first embodiment and abstracting method, utilize the pressure reduction of barometric point and deep sea water column pressure on the sea level, the pressure that mainly utilizes the deep-sea to locate seawater carries out reverse osmosis, is 60Kg/cm as the sea pressure 600 meters depths
2, about 5.89Mpa/cm
2Filtration, purification layer and desalination layer 11 that seawater directly penetrates in the desalination system 1 enter desalination pipe 12, water first class purification and desalination in the desalination pipe 12, by fresh water communicating pipe 13 desalination water being imported fresh water stores in the water container 51 in the transport control system 5, water pump 52 promotes the desalination water supercharging, by hydraulic pipe 53 output seas, can is produced then.
Pressure reduction in the desalination system 1 keeps by atmospheric communicating pipe 56 and hydraulic pipe 53, and wherein an end of atmospheric communicating pipe 56 is communicated with water container 51.
Water level and hydraulic pressure in the desalination system 1 are transferred to the sea supervisory console by pressure transmitter 55, are monitored by operator.
Total system can be led by hawser or suspender member 6 and be hung, and sinks in the deep-sea, and by transmitting electric power on the sea, is connected on the water pump 52 by power lead 54, and the other end of hawser 6 can be affiliated on boats and ships, also can be affiliated on stationary platform.
Referring to Fig. 2, sea water in deep sea desalination and abstracting method as second embodiment, filtration, purification layer and desalination layer 11 that penetration of sea water is crossed in the first step desalination system 1 enter desalination pipe 12, water in the desalination pipe 12 is tentatively desalination, by fresh water communicating pipe 13 desalination water is imported and is carried out the desalination second time in the second stage desalination system 2.Second stage desalination system 2 is equipped with desalination layer 21, be together in series before and after respectively between the every desalination pipe 22, desalination layer 21 skin of every desalination pipe 22 are provided with chuck 26, on chuck 26, be provided with water-in, and water outlet is arranged at a wherein end mouth of pipe of every desalination pipe 22, and last root desalination is managed 22 by on the water container 51 that is connected to fresh water communicating pipe 23 in the fresh water storage transport control system 5.
The dope that is produced in desalination second time process enters the sea by dope pipe 25 by concentrate pump 24.The water pump 52 that fresh water stores in the transport control system 5 promotes the desalination water supercharging, and by hydraulic pipe 53 output seas, can is produced then.
Referring to Fig. 3, sea water in deep sea desalination and abstracting method as the 3rd embodiment, filtration, purification layer and desalination layer 11 that penetration of sea water is crossed in the first step desalination system 1 enter desalination pipe 12, water in the desalination pipe 12 is tentatively desalination, by fresh water communicating pipe 13 desalination water is imported and is carried out the desalination second time in the second stage desalination system 2.Second stage desalination system 2 is equipped with desalination layer 21 equally, every desalination pipe 22 is in series mutually, desalination layer 21 skin of every desalination pipe 22 are provided with chuck 26, to be connected in fresh water communicating pipe 13 on desalination layer 21 chuck 26 of the first desalination pipe 221, be connected with the desalination layer chuck 26 of the second desalination pipe 222 by the desalination layer chuck 26 of a dope pipe 25 again the first desalination pipe 221, the desalination layer chuck 26 of the second desalination pipe 222 is connected by the desalination layer chuck 26 of a dope pipe 25 with the 3rd desalination pipe 223 again, every desalination pipe 22 all has a water outlet to be connected in fresh water communicating pipe 23, and fresh water communicating pipe, 23 water containers 51 that store in the transport control system 5 with fresh water were connected.
