Description

Marine drinking water production equipment using seawater

The present invention relates to an apparatus for manufacturing drinking water for ships using sea water.

More specifically, after dissolving oxygen in the air or oxygen tank in the sea water by pumping sea water, various foreign substances contained in sea water are first filtered by a pre-treatment filter, and desalted by a reverse osmosis filter to separate into fresh water and sea water. In addition, the final drinking water is obtained by re-filtering the fine foreign matter contained in fresh water by a post-treatment filter and sterilizing the bacteria contained in the fresh water by a sterilization lamp. The present invention relates to an apparatus for manufacturing drinking water for ships using sea water that can provide drinking water.

In general, in order to obtain fresh water from sea water, dissolved or suspended components in sea water must be removed to meet the water and drinking water standards, and in the seawater desalination method, reverse osmosis and electrodialysis using a special membrane, and seawater is converted to steam to desalination. Other methods include evaporation, freezing, and solar heating. However, evaporation and reverse osmosis are mainly used for desalination, and reverse osmosis and electrodialysis are mainly used for desalination.

In the seawater desalination facility by the reverse osmosis membrane method, ionic substances dissolved in water are almost excluded, and ionic substances dissolved in seawater are filtered by a semi-permeable membrane (membrane) through which pure water passes. In order to separate ionic substances and pure water from seawater, a high pressure of osmotic pressure or higher is required. The pressure at this time is called reverse osmosis, and in the case of seawater desalination, a high pressure of about 42 to 70 bar is required.

As a prior art using such a reverse osmosis membrane method, a water purification method using a membrane separation device of Patent No. 402556 shown in FIG. 1 has been disclosed.

The prior art undergoes a correction process for pressure, ph, flow rate, and temperature in order to make raw water suitable for filtration in a membrane separation device. In particular, in temperature, the temperature of water is low in winter, so it is relatively filtered compared to summer. Since the efficiency is lowered, the temperature of the water is kept constant using a heat exchanger, and then the membrane separation device 5 is passed through.

The above prior art uses a heat exchanger having a large amount of heat and power consumption, and the energy consumption is large when it is continuously applied as the water temperature is kept constant. Even if solar heat, geothermal heat, waste heat steam, etc. are used in consideration of energy consumption, the device itself There was a problem that the number of increases.

Attached Figure 2 is a configuration diagram of a drinking water production apparatus for ships using sea water according to the present invention, Figure 3 is a view listing a main portion of a drinking water production apparatus for ships using sea water according to the present invention in-line.

According to the above drawings, the apparatus 100 for producing drinking water for ships using seawater according to the present invention includes a housing 200, a seawater inflow pump 300, a pretreatment filter 400, a reverse osmosis membrane filter 500, a high pressure pump 600, A post-treatment filter 700 and an ultraviolet sterilizer 800 may be included.

The housing 200, which is a part of the apparatus 100 for manufacturing drinking water for ships using seawater according to the present invention, may be in the form of a rectangular box in which a chamber is provided to embed parts therein. Here, the space dividing frame 210 in the form of a square box may be fixedly installed in the chamber of the housing 200 for space dividing.

The space dividing frame 210 is installed at the center of the chamber of the housing, so that the first and second pump chambers 201 and 202 are formed on both sides, and the filter chamber 203 is formed on the space dividing frame itself, resulting in a total of three spaces. It can be divided. In addition, an upper space 204 is formed between the space division frame 210 and the upper side of the housing 200.

A filter fixing bracket 211 for fixing the pre-processing filter 400 and the post-processing filter 700 may be provided on the inner upper side of the space division frame 210. Although the coupling structure of each filter and the filter fixing bracket is not specified, it is preferable that the filter is firmly fixed as a screw in view that each filter can be flowed by a fluid flow.

On the other hand, the housing 200 may be made of a metal, considering that corrosion may occur by seawater, an anti-corrosion film may be attached to the outer surface by an adhesive. Here, the adhesive composition is 40 to 80 parts by weight of a thermoplastic resin, 5 to 40 parts by weight of an adhesive resin, 1 to 5 parts by weight of a resin, 1 to 10 parts by weight of a plasticizer, 1 to 10 parts by weight of a filler, and 0.1 to 1 parts by weight of an antioxidant Includes. The adhesive composition is a heat-melting adhesive composition, and is generally prepared in a state of being adhered between a release agent and a corrosion-preventing film, and then adheres to the surface of the housing by performing a press operation after removing the release agent when adhering to the housing 200 as an adherend. can do. Hereinafter, look at each component in detail.

The thermoplastic resin is a main component of the composition, and functions to control adhesion and cohesion. If it contains a vinyl group or a hydroxyl group, the type is not particularly limited, for example, ethylene vinyl acetate copolymer, polyvinyl acetate, polyvinyl alcohol, ethylene-acrylic acid copolymer and ethylene-methacrylic acid copolymer, polyurethane It may be composed of any one or more selected from the group consisting of.

The content of the thermoplastic resin is preferably 40 to 80 parts by weight relative to the total composition. If the content is less than 40 parts by weight, the melt viscosity increases and the melt flow index decreases, resulting in very low workability. When the content exceeds 80 parts by weight, it is difficult to exert sufficient adhesion to be applied directly to the fabric.

The tackifying resin is a low molecular weight resin, which improves workability by lowering melt viscosity, improves initial wetness of adhesion and adhesion on the surface of the adhesive material, and enables control of solidification time.

The type of the tackifying resin is not particularly limited, but is preferably a petroleum resin. More specifically, the tackifying resin may be composed of at least one selected from the group consisting of aliphatic hydrocarbon resins, alicyclic hydrocarbon resins, aromatic hydrocarbon resins, aromatic modified aliphatic hydrocarbon resins, and hydrogenated hydrocarbon resins.

The aliphatic hydrocarbon resins include commercial products such as Hikorez A-1100, Hikorez A-1100S, Hikorez C-1100, Hikorez R-1100, Hikorez R-1100S of Kolon Oil Corporation. In addition, cycloaliphatic hydrocarbon resins include hydrocarbon resins containing dicyclopentadiene (DCPD) as a monomer, and aromatic hydrocarbon resins are commercially available from Kolon Petrochemical's Hikotack P-110S, Hikotack P-120, Hikotack P-120HS, Hikotack P-120S, Hikotack P-140, Hikotack P-140M, Hikotack P-150, Hikotack P-160, Hikotack P-90, Hikotack P-90S, Hirenol PL-1000, Hirenol PL-400, etc. In addition, aromatic hydrocarbon resins modified by aromatics include commercially available Koko Emulsion Hikorez T-1080 and Hikorez T-1100. In addition, the hydrogenated hydrocarbon resin may be subdivided into a hydrogenated aliphatic hydrocarbon resin, a hydrogenated aromatic hydrocarbon resin, etc., commercially available from Kolon Oil Corporation Sukorez D-300, Sukorez D-390, Sukorez SU-100, Sukorez SU-110, Sukorez SU-120, Sukorez SU-130, and Sukorez SU-90.

The tackifying resin is preferably a hydrocarbon resin having 4 to 10 carbon atoms in the monomer, specifically C5 aliphatic resin, C9 aromatic resin, C5 / C9 aliphatic / aromatic copolymer resin, and the like.

In addition, the tackifying resin is more preferably characterized in that it is a hydrogenated hydrocarbon resin containing dicyclopentadiene as a monomer, commercially available from Kolon Oil Corporation (Korea) Sukorez D-300, Sukorez D-390, Sukorez SU -100, Sukorez SU-110, Sukorez SU-120, SukorezSU-130, Sukorez SU-90, etc.

Meanwhile, in order to minimize contamination, the adhesive composition is preferably used by mixing biodegradable hypoallergenic resins together with various petroleum resins described above.

The biodegradable hypoallergenic resin may be prepared by melt mixing a polymer monomer with a biodegradable polymer, and polylactic acid is preferably used as the biodegradable polymer.

The polylactic acid is a polyester synthesized by condensation polymerization of lactic acid or ring-opening polymerization of lactide, and has a medium property between polyamide and polyethylene terephthalate, and mainly uses natural vegetable sugar components obtained from potatoes and corn as raw materials. The biodegradability is high, but in general, it has high hardness, low elasticity, and poor durability.

The biodegradable polymer is melt-mixed with the same polymer monomer, wherein the biodegradable polymer is partially combined with the monomer, resulting in partial chain breakage, resulting in a lower number average molecular weight. As the number average molecular weight falls, it exhibits physical properties that can be used as an adhesive, and processability increases.

With respect to 100 parts by weight of the polylactic acid, the lactic acid monomer may be mixed with 20 to 30 parts by weight. When the monomer is mixed to less than 20 parts by weight, the number average molecular weight is high and hard to be used as an adhesive, and when the monomer exceeds 40 parts by weight, migration may occur on the surface, which may also be difficult to use as an adhesive.

The content of the adhesive resin is preferably 5 to 40 parts by weight compared to the total composition. If the content is less than 5 parts by weight, there is a fear that the effect of lowering the melt viscosity due to the addition of the tackifying resin is insignificant and the increase in the melt flow index is not so great that the workability may not reach a satisfactory level, and the content exceeds 30 parts by weight. When the tackiness resin is exceeded, the increase in the melt flow index is not large, so economic efficiency is lowered and the content of the thermoplastic polymer is reduced, which may decrease the overall physical properties of the composition.

The rosin serves to improve the overall adhesion of the adhesive composition, is harmless to the human body and acts as a natural preservative. The content of the rosin is preferably 1 to 5 parts by weight compared to the total composition. If the content is less than 1 part by weight, it is difficult to obtain an effect of improving the adhesive strength, and if the content exceeds 5 parts by weight, the adhesive force increases during processing, which makes it difficult to process the product.

The plasticizer is used to impart flexibility and adhesion to the polymer, and the type of the plasticizer according to the present invention is not particularly limited, for example, sorbitol, ethylene glycol, glycerin, glycerin diacetate, and pentaerythritol. It may be composed of one or more selected from the group consisting of.

The content of the plasticizer is preferably 1 to 10 parts by weight relative to the total composition. If the content is less than 1 part by weight, the effect of adding the plasticizer is insufficient, and if the content exceeds 10 parts by weight, the economical efficiency may be deteriorated due to the excessive use of the plasticizer, and there is a fear of deteriorating the overall physical properties of the adhesive.

The filler is used to control the reinforcement and flowability of the composition. The type of filler is not particularly limited, and for example, calcium carbonate, clay, bentonite, or calcium stearate may be used.

The seawater inflow pump 300, which is a part of the drinking water production apparatus 100 for ships using seawater according to the present invention, is built into the first pump chamber 201 of the housing 200 to pump seawater from the beach to the pretreatment filter. It serves to transmit to (400). Although not particularly specified, the seawater inflow pump 300 may be applied to a horsepower (HP), and the rated voltage is preferably AC 220V.

The pre-treatment filter 400, which is a part of the apparatus 100 for producing drinking water for ships using seawater according to the present invention, is fixed to the filter fixing bracket 211 provided in the filter chamber 203 as a screw, and the seawater inflow pump ( 300) may be composed of a plurality of foreign substances contained in the seawater that has been pumped from and sequentially filtered by size to filter.

The pretreatment filter 400 filters the foreign matter (floating matter) of 10 microns or more, for example, a filter directly connected to the seawater inflow pump 300, and the next filter positioned next to the filter may filter foreign matter between 10 and 5 microns, for example. Can be. The reason for constructing multiple pretreatment filters is that the clogging cycle caused by foreign matter is fast when only one filter is formed, so care must be taken accordingly. However, if the dispersion is multiple, the clogging cycle is relatively slow. Because it is.

A reverse osmosis filter 500, which is a part of the apparatus 100 for manufacturing drinking water for ships using seawater according to the present invention, is installed in the upper space 204 formed between the space division frame 210 and the upper side of the housing 200 , It serves to separate the fresh water and seawater by desalting the seawater primarily filtered by the pretreatment filter 400 by a separation membrane.

Here, the RO membrane filter may be applied to the reverse osmosis membrane filter 500.

For reference, reverse osmosis (RO) refers to a process of obtaining fresh water with high purity by removing solute dissolved in sea water using a semi-permeable membrane and osmotic pressure. When the same amount of low-concentration solution and high-concentration solution are placed between semi-permeable membranes, the amount of high-concentration solution gradually increases over time, and the amount of high-concentration solution no longer increases after a certain period of time. Not to reach equilibrium. This is called osmosis, and the difference in head between high and low concentration solutions in equilibrium is called osmotic pressure. When a pressure higher than the osmotic pressure is applied to the high-concentration solution in the equilibrium state, water, which is a solvent of the high-concentration solution, passes through the membrane and moves toward the low-concentration solution, and the solute cannot pass through the membrane, which is called reverse osmosis. The process of separating the solvent water from the solute from the pressurized brine using a semi-permeable membrane is called a reverse osmosis method.

The high-pressure pump 600, which is a part of the apparatus 100 for producing drinking water for ships using seawater according to the present invention, is provided in the second pump chamber 202 and provides high pressure to the seawater that has passed through the pretreatment filter 400. By acting to allow the reverse osmosis membrane filter 500 to easily permeate.

Here, the reverse osmosis membrane filter 500, the lower the temperature, the lower the pressure of the high pressure pump 600 in the summer to provide a high temperature environment to produce a constant flow of fresh water as the osmotic pressure increases and the freshwater productivity decreases. In the winter season providing a low temperature environment, the pressure of the high pressure pump 600 should be set relatively high.

Previously, the design pressure of the high pressure pump was designed based on the seawater temperature in winter to keep the production volume constant regardless of the season, but in the summer, the high pressure pump pressure is higher than necessary, resulting in unnecessary energy consumption. To improve this, an inverter (not shown) is used to control the motor rotational speed of the high-pressure pump to reduce irrational energy consumption due to changes in the temperature environment, and when the inverter is used, the rotational speed when the high-pressure pump is initially driven Can be increased linearly and slowly, so it can reduce the initial starting load that occurs because it is driven up to the maximum number of revolutions at the moment of initial driving in a general high-pressure pump, and the starting change of the motor is also gradually flexible. This prevents excessive operation of the devices, and it is also easy to operate and adjust to change the flow rate and pressure.

For reference, the high-pressure pump 600 may be applied to a 3-horsepower (HP), the rated voltage is preferably AC 220V. Further, the maximum pressure is 100 Bar, and the working pressure is preferably 50 Bar.

The post-treatment filter 700, which is a part of the apparatus 100 for producing drinking water for ships using seawater according to the present invention, is disposed in the filter chamber 203 and remains in fresh water that has passed through the reverse osmosis filter 500. It plays a role in filtering foreign substances again.

The post-treatment filter 700 may include a mesh carbon filter 710, a blue carbon filter 720, and a UF membrane filter 730 through which fresh water passing through the reverse osmosis filter 500 sequentially passes.

The blue carbon filter 720 contains a small amount of elements such as oxygen, hydrogen, and sulfur, as well as coarse particles and moisture, in addition to carbon (about 93% of coal-based), and the functional groups of carbon atoms present on the inner surface are around It has the property of adsorbing molecules of the adsorbed substance by applying an attractive force to the liquid or gas.

The UF membrane filter (UF hollow fiber membrane) 730 is a porous filter having pores of tens to hundreds of nanometers in size, passing only water through a myriad of micropores distributed on the surface of the membrane to remove contaminants present in the water. It functions to remove.

The ultraviolet sterilizer 800, which is a part of the drinking water production apparatus 100 for ships using seawater according to the present invention, is installed in the upper space 204 formed between the space dividing frame 210 and the upper side of the housing 200, The fresh water that has passed through the post-treatment filter is ultraviolet-sterilized, so that the final drinking water is obtained.

Meanwhile, the apparatus 100 for manufacturing drinking water for ships according to the present invention connects the oxygen inlet pipe P ₂ to the seawater transfer pipe P ₁ transferred from the seawater inflow pump 300 to the pretreatment filter 400, and the seawater is transferred. Oxygen can be dissolved in seawater transported through the pipe (P ₁ ). Therefore, high-quality drinking water rich in dissolved oxygen is provided.

Here, the entrance end of the oxygen injection pipe (P ₂₎ is the oxygen tank 900 is connected is put the oxygen in the oxygen tank with oxygen injection pipe (P _2).

Figure 4 is a flow chart of a method for producing drinking water using a drinking water manufacturing apparatus for ships using sea water according to the present invention.

According to FIG. 4, the method for manufacturing drinking water of the present invention will be briefly described since it has been mostly described in the previous device description.

1) The seawater is pumped by the seawater inflow pump 300 and supplied to the pretreatment filter 400. In this process, when oxygen is injected by a high pressure pump, it is dissolved in sea water in a microbubble state (S100). This is a process for providing drinking water rich in dissolved oxygen.

2) The foreign matter contained in the seawater is first filtered by passing the seawater in which oxygen is dissolved through the pretreatment filter 400 (S200). Here, it is a process of hanging a relatively large sized float.

3) The filtered seawater is supplied to the reverse osmosis membrane filter 500 by a high pressure pump 600 in a high pressure state (S300). The seawater that has passed through the reverse osmosis membrane filter 500 is desalted and separated into fresh water and seawater, and the seawater is discarded and only freshwater is continuously processed.

4) The separated fresh water is passed through a post-treatment filter 700 to filter the final foreign matter (S400).

5) Sterilized fresh water after all the foreign matter filtration is sterilized by an ultraviolet sterilizer 800 to finally make drinking water (S500).

Although the above-described embodiment is described for a preferred embodiment of the present invention, it is stated that the present invention is not limited thereto and can be implemented by changing to various forms without departing from the technical spirit of the present invention.
