Hereinafter, various embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. However, in describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted.

1 is a view for schematically explaining a driving concept of an aquarium system (100 of FIG. 6) according to an embodiment of the present invention.

Referring to FIG. 1, the aquarium system 100 includes a tank 10 in which marine organisms live as a place where marine marine organisms (polar creatures) are polarized. The water tank 10 may include one or more water tanks, and the water temperature of the water tank 10 may be set to 0.5 degrees Celsius. However, the water temperature of the water tank 10 may be set lower than or higher than 0.5 degrees if the marine life can normally live. In the present specification, it is assumed that the living water temperature of marine life is 0.5 degrees Celsius.

Polar marine organisms (polar creatures) naturally release wastes (eg, ammonia), and they can survive only when the wastes are filtered from the seawater containing the wastes. However, in order for the waste to be filtered, the water temperature must be set to about 10 degrees Celsius, so that the drained water containing the waste should be set to 10 degrees Celsius (20). However, the temperature of 10 degrees Celsius may be set differently for the efficiency of the filtration. In this specification, it is assumed that filtration is performed at 10 degrees Celsius or 12 degrees Celsius. Here, a heat exchanger may be used to increase the temperature of the drained water.

Next, 10 degrees Celsius of water may be filtered (30). The aquarium system 100 may further include various filtration modules so that the drained water is effectively filtered.

The aquarium system 100 sets 40 so that the filtration is complete and the purified water is 0.5 degrees Celsius. 0.5 degree Celsius water is supplied to the water tank 10 can be a healthy marine life.

Here, the temperature of the place where the aquarium system 100 is applied according to an embodiment of the present invention may be set to room temperature (eg, 25 degrees Celsius). Accordingly, the marine life living in the polar can be reared without problems even in the local space of the polar, and the research convenience of the researcher can be guaranteed.

2 and 3 are views for explaining the heat exchangers (HE1, HE2) according to an embodiment of the present invention.

Heat exchangers are heat exchangers that allow mediums of different temperatures to approach each other to share (interchange) the heat of the medium. One embodiment of the present invention uses a plate heat exchanger, the heat exchanger of various methods may be applied according to the embodiment. Plate heat exchangers include a structure that allows heat exchange to take place using hot plates, with the hot plates passing through the hot medium on one side and the cold (less hot) medium between the hot plates to transfer heat from the hot medium to the cold medium. .

In the present invention, when the temperature of seawater in which polar marine organisms live is set to 0.5 degrees Celsius, and the temperature of seawater for filtration is 12 degrees Celsius, water in one direction 210A obtained through the first heat exchanger HE1 is provided. The temperature is 0.5 degrees Celsius, and the water 220A in the other direction obtained by the first heat exchanger HE1 is 12 degrees Celsius. Here, water 210A in one direction is water obtained from the return sump of FIG. 6 to be described above, and water 220A in the other direction may be implemented as water obtained from the main sump.

The water 210A in one direction and the water 220A in the other direction may be changed into

water

210B and 220B of an intermediate temperature in the heat exchanger and discharged. Here, the

water

210B and 220B of the intermediate temperature may be 2 degrees Celsius. The second heat exchanger HE2 receives water 220B in one direction and cold water (minus 2 degrees Celsius 230A, for example, antifreeze), and cold water 230B and water at 220 degrees Celsius at 220 degrees Celsius. Can be.

According to one embodiment of the present invention, a plurality of heat exchangers (HE1, HE2) having two inlet / outlet lines for each heat exchanger is applied, the aquarium system 100 can have a more diverse structure, The water coming out can be set to a temperature that suits your needs.

In addition, the heat exchanger may be further included. If a plurality of heat exchangers are configured, the temperature to be set can be set faster and easier. For example, when a plurality of heat exchangers are additionally included, temperature setting for filtration of marine life and temperature can be easily and quickly performed. In addition, if the heat exchanger is further included, more configurations may be added to the system, thereby increasing the implementation diversity of the system.

Referring to Figure 3 describes the structure of the heat exchanger according to an embodiment of the present invention, the heat exchanger support 310, guide bar 320, fastening plate 330, tightening bolt 340, carrier 350 ), A hot plate pack 360 and a fixed plate 370 may be provided.

Hereinafter, the configuration of the main filtration unit 110 for removing waste products from marine life will be described with reference to FIG. 4. The main filtration unit 110 is a module for filtering water from the main sump, which is a main drainage tank, and may filter the water supplied to the main sump.

The main filtration unit 110 includes a sensor unit 111 and a filtration unit 113. However, since the configurations of the main filtration unit 110 shown in FIG. 4 are not essential for configuring the main filtration unit 110, the main filtration unit 110 described in the present specification is more than the components listed above. Or may have fewer components.

The sensor unit 111 of the main filtration unit 110 includes a water temperature sensor 111WT, a DO sensor 111DO, a pH sensor 111pH, and a water level sensor 111DW. Water temperature sensor 111WT is a module for measuring the water temperature of the main sump, DO sensor 111DO is a module for measuring the dissolved oxygen (Dissolved Oxygen), pH sensor (111pH) is a module for measuring the pH of water, water level sensor This module measures the level of the main sump of (111DW).

The sensor unit 111 may provide a notification to the main controller (160 of FIG. 6) when a problem occurs in water temperature, DO, pH, and water level of the main sump. The main controller 160 may appropriately cope with a problem caused by the sensor unit 111. For example, the main controller 160 operates a pump for circulation of seawater when the water temperature is low, when the dissolved oxygen level is high, when there is a pH problem, and when there is a water level problem. Can be operated.

The filtering unit 113 may include an ultraviolet sterilizing unit 113UV, a sand filter 113SF, a bubble dividing unit 113FF, a line filtering unit 113CF, and the like.

Specifically, the line filtration unit 113CF is a module for filtering foreign substances, etc. contained in water, and is a module for performing filtration before passing through a heater. Since a plurality of outlet points of the heat exchanger are used, a water temperature for filtration may be set by using a separate heater using one outlet point.

The ultraviolet sterilization unit 113UV may remove various harmful bacteria / viruses / pathogens in a short time by using UV (ultraviolet rays). UV sterilization unit 113UV can be used where disinfection is needed, and sterilization by UV (ultraviolet) does not require the use of chemicals such as chlorine. It does not need to remove other by-products in the future because it does not process anything in the water. Moreover, since it does not change the physical and chemical properties of the water, pH, color, smell, temperature, etc. can be kept intact. It can be applied to recycling water, live fish tank of sashimi, and drinking water sterilization of water purifier. Ultraviolet sterilization hardly changes the irradiated objects, and the sterilization effect is limited during irradiation and does not remain, which is suitable for sterilizing air and water.

The sand filter 113SF may adsorb, filter, and decompose contaminants using microorganisms that are introduced into and grow on the surface of the filter medium by introducing seawater into a container containing a filter medium such as sand and gravel. In addition, the sand filter 113SF may be used as a circulating water filtration device. Here, sand is used for the removal of solids and suspended solids, and activated carbon is a filter for adsorption capacity of organic substances, residual chlorine, and fine solids. It can be periodically discharged by backwashing to drain it out.

The foam fractionator (113FF) is an abbreviation of Foam Fractionator, also known as Protein skimmer. The foam fractionator (113FF) was originally developed for use in industrial sewage treatment plants, and organic matters (proteins) dissolved in water It can be removed through the foam before it is broken down into ammonia. The bubble classification unit 113FF uses the principle that organic molecules adhere to the surface (bubble) of air bubbles injected into the water column due to polarity of the molecules, and the generated bubbles can be discharged at the end and remove organic impurities. have. That is, the bubble classification unit 113FF can discharge the organic matter as much as possible through the bubbles, and since this process of the bubble classification unit 113FF occurs well in high pH and salinity water, the bubble classification unit 113FF is a seawater tank. It can be used effectively in this type of filtration, this type of filtration can help to keep the water quality good.

5 shows a process in which the aquarium system 100 decomposes ammonia according to an embodiment of the present invention.

First, the aquarium system 100 removes ammonia through the oxidation of bacteria (nitrite bacteria in Nitrosomonas) that live on the surface of the filter medium when ammonia generated from the excretion of polar marine organisms, leftover feed residues and proteins passes through the filter medium. And nitrite (NO2). Next, the aquarium system 100 may produce nitrate (NO 3) which is almost non-toxic by another bacterium (Nitrobacter). Aquarium system 100 may supply purified water to a header tank, which may supply a plurality of baths and return sumps.

In other words, the aquarium system 100 allows nitrite (nitrosomonas) to decompose ammonia (harmful) to produce nitrite (harmful), and nitrate (nitrobacter) to decompose nitrite to produce nitrate (harmless). do. However, the aquarium system 100 can effectively decompose ammonia by setting the water temperature at 10 degrees Celsius or more during filtration.

6 is a view for explaining the configuration and operation of the aquarium system 100 according to an embodiment of the present invention.

According to FIG. 6, the aquarium system 100 includes living and filtration areas of polar marine life. The temperature of the living area and the filtration area can be set to room temperature, so it is not necessary to lower the room temperature by operating an air conditioner, etc., so that research on marine life can be easily performed.

In another embodiment, the living zone may be set at a low temperature at which marine life may live, and the filtration zone may be set at a normal temperature at which an operator may easily work.

The living area and the filtration area may be arranged together in one open space, and the living area may be arranged in the lower layer and the filtration area in the upper layer. In this case, a vertical elevator or the like may be installed to facilitate the movement of the researcher from the living area to the filtration area. When a vertical elevator is installed, when the vertical elevator moves from the living area on the first floor to the filtration area on the second floor, the first and second floors can be structurally completely isolated. That is, the lower surface of the vertical elevator reaches the second floor may serve as a door.

In addition, since the living area and the filtration area are provided in separate places (also, pipes in which seawater moves), the use of the place may be more efficient.

The detailed configuration and functions of the aquarium system 100 will be described in detail. First, a plurality of tanks S1 to S6 and C1 to C4 in which marine life is managed may be disposed at a first water temperature.

Here, the first water temperature may be 0.5 degrees Celsius, and may be variously set according to marine life. The material of each of the square tanks (S1 to S6) of the plurality of tanks is PVC (PolyVinyl Chloride), and a filler (for example, styrofoam) is disposed between the plates of a single layer to prevent condensation due to temperature differences. This can be maintained. Square tanks (S1 to S6) is efficient in a narrow space and may include a color other than the transparent tank to minimize external stimulation for the experimental organism.

In addition, the circular tanks (C1 to C4) is disposed, the circular tanks (C1 to C4) is the structure of the least stress to the fish, it may be advantageous to remove foreign matters collected in the center of the flow of water flow. However, when the area where the aquarium system 100 is disposed is narrow, it may be preferable to install only a small amount.

In addition, an M1 bath may be disposed between C1 and C2 and an M2 bath between C3 and C4. M1 and M2 tank can perform the water level control of the circular tank (C1 to C4), the water level can be stressed by inserting the water rod directly into the circular tank (C1 to C4) to adjust the water level, when collecting the water rod Since interference may occur, it may serve to prevent this. In addition, the M1 and M2 tanks can precipitate sediments generated during the passages of the circular tanks C1 to C4, and there may be small organisms in the circular tanks C1 to C4. Can be prevented.

The display sump 143 is a display tank that does not directly affect the aquarium system 100 but corresponds to a tank that visitors interested in polar marine fish can observe from outside. Since the experimental tanks should minimize external influences in order to minimize stress of the creatures, marine life can be observed through the exhibition tanks.

The return sump 141 is supplied with water before filtration from the plurality of water tanks S1 to S6 and Display Sump C1 to C4. Thus, the return sump 141 may include excretion of marine life. In some embodiments, the return sump 141 may be designed to supply purified water to a plurality of tanks. In addition, since the return sump 141 has one water pipe and a pump circulating to the main sump, the water of the breeding tank can be collected and circulated at a time, and the precipitate generated during the experiment tank can be settled.

In addition, a work-bench of researchers may be additionally arranged in the living area.

In the filtration area, a first heat exchanger HE1 and a second heat exchanger HE2 may be arranged to set the temperature of water received through a plurality of input channels in a heat exchange manner. The driving of the first heat exchanger HE1 and the second heat exchanger HE2 will be omitted as described with reference to FIG. 2.

The header tank 135 receives the water of the first water temperature output from the second heat exchanger HE2 and the plurality of tanks S1 to S6, Display Sump C1 to C4, and the return sump 141. ) Can be provided. The water from the header tank 135 is filtered water.

In addition, the header tank 135 may be provided with a water temperature sensor (WT), dissolved oxygen sensor (DO), pH sensor (pH), water level sensor (DW), the dissolved oxygen sensor (DO) is introduced into the air In addition, it is possible to artificially supply oxygen through a blower.

The above sensors may help to overcome problems that may occur when the aquarium system 100 is automatically driven.

The main chiller 133 may supply water lower than the first water temperature to the second heat exchanger such that the water provided from the second heat exchanger HE2 to the header tank 135 becomes the first water temperature. Here, water lower than the first water temperature may be minus 2 degrees Celsius as an antifreeze, and may be implemented differently according to the living water temperature of marine life, the water temperature for filtration, and the like.

The main chiller 133 serves to finally cool the seawater to the target set temperature, and after cooling the antifreeze to the set temperature in the chiller, the main chiller 133 may exchange heat with seawater.

In an embodiment, when the water provided to the header tank 135 from the second heat exchanger HE2 is higher or lower than the first water temperature, the main controller 160 may adjust the set temperature of the main chiller 133.

The main sump may supply water after filtration at a second temperature to the first heat exchanger 130HE1. The main sump may include a main filtration unit 110 to purify water at 10 degrees to 12 degrees Celsius.

The main sump is a water tank that must be passed through the breeding water, and serves as a filtration tank. The main sump can filter out suspended solids, can be placed filter media for the proliferation of filter bacteria, and is composed of microorganisms (probiotics) that are beneficial to fish by using biofloc technology. It is possible to fundamentally prevent nitrous acid poisoning by rapidly decomposing and liquefying organic matters such as food waste and excreta of farms. Here, BaoFlock technology is a new aquaculture technology that excels in degrading pollutants and raises microorganisms that are beneficial to fish in aquaculture tanks with fish, and microorganisms decompose contaminants generated from feed debris or feces, and are eaten by fish to provide nutrients such as proteins. It is aquaculture technology that saves water and energy because it does not need water change.

The main filtration unit 110 may perform pre filtration CF on water having a third temperature between the first temperature and the second temperature output from the first heat exchanger. The line filtration unit 113CF of the main filtration unit may previously filter foreign matters or the like with a filter before passing through the heater. The line filtration unit 113CF may serve to maximize water stability and heating performance. Thereafter, the activity of bacteria (nitrobacter and nitro zommonas) that efficiently removes nitrite and nitrate generated during ammonia removal may be increased by heating through a heater. Here, too, since the inlet and outlet points of the heat exchanger are plural, the water temperature control can be efficiently performed.

In addition, the main filtration unit may filter foreign substances contained in water through the ultraviolet sterilization unit 113UV, the sand filter 113SF, and the bubble classification unit 113FF described in detail with reference to FIG. 4.

The sub-chiller 137A and 137B may be further included together with the main chiller 133. The service chiller is 3 horsepower per vehicle, and it is urgently necessary to prevent biological breeding when necessary such as an unexpected failure or inspection of the main chiller (15 horsepower). It is intended to be used as a spare means, and it can also be used as an auxiliary cooler by simultaneously operating so that the cooler is not overwhelmed by lack of main chiller capacity in the hot summer season. Two subchillers (preliminary coolers) may be more efficient than two units for the sake of cooling capacity or safety due to failure.

The controller coupled to each of the sub-chillers 137A and 137B includes a cooler power button and a temperature setting button so that the controller may be preliminarily operated when the main cooler malfunctions or other needs. The controllers can be driven simultaneously or separately.

In addition, BP (Balance Pipe) may be installed for adjusting the water pressure (flow rate). In particular, proper flow rate adjustment (circulation speed) is required for the optimal conditions of circulating water heat exchange in the heat exchanger. In this case, BP can control the water pressure (flow rate) through mutual pressure control from each tank.

The main controller 160 may drive an operation and emergency alarm system of each tank for breeding water circulation. The main controller 160 may operate automatically, but may be manually operated when necessary.

In addition, an external seawater tank 150 may be added. The external seawater tank 150 may be a tank size (2 tons) because a sufficient reserve is required as a tank for storing seawater in advance. If it is difficult to store indoors due to the specification, it may be placed outside and a hot wire may be arranged to prevent freezing of sea water in winter.

In addition, since the temperature may affect the water temperature, a thermal insulation material for preventing heat loss of breeding water may be disposed in each tank, such as a tank cover or a water pipe.

In addition, a plurality of pumps may be arranged. For example, a plurality of first pumps for transporting water from the return sump 141, a plurality of second pumps for supplying water from the main sump to the first heat exchanger, and water from the header tank 135 may be used. A plurality of tanks and a third pump for supplying the return sump 141 may be disposed. However, the number of pumps may vary depending on the implementation.

On the other hand, this specification is not intended to limit the invention to the specific terms presented. Thus, while the present invention has been described in detail with reference to the above examples, those skilled in the art can make modifications, changes, and variations to the examples without departing from the scope of the invention. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.
