Description

{Air circulation system for prevent green tide}

The present invention relates to an air circulation system for preventing algae, and more particularly, to an air circulation system for preventing algae by injecting air and water into the system, such as a river.

The green algae phenomenon is a phenomenon in which green algae grow in large quantities in lakes or rivers due to an excess of nutrient salts and the color of the water changes to green.

The green algae phenomenon as described above is rich in perishable organic pollutants, trace metals and proliferation promoting substances, and environmental conditions such as solar radiation and water temperature are required. It is known to be an important condition.

In other words, if an excess of domestic sewage and manure containing organic matter flows into rivers, lakes, rivers, etc., microorganisms decompose the organic matter in excess, resulting in eutrophication, which increases nutrients in the water body. (Biochemical Oxygen Demand, BOD) increases, and aquatic organisms such as fish cannot survive due to lack of oxygen in the water. ) is there.

In particular, when the temperature rises, stratification intensifies and oxygen from the surface of the lake becomes difficult to transfer to the bottom of the lake, the amount of dissolved oxygen in the bottom of the lake drops sharply, and as a result, the destruction of the ecosystem is further aggravated. However, it is difficult to prevent the deterioration of water quality due to the habitual occurrence of algae every year and to relieve aesthetic discomfort because it causes difficulties in facility management due to the excessive cost burden caused by the removal of algae. there has been In general, the three factors of algae phenomenon are photosynthesis (light, nutrients), water temperature, and water flow rate.

Therefore, research on water treatment technology such as the development of a system or device for preventing the algae phenomenon as described above has been actively conducted until recently.

First, an approximate configuration of an air circulation system for preventing algae according to the present invention will be described with reference to FIG. 1 .

As shown, the air and water discharged through the air circulation system are mixed with the air circulation system that receives the water with the water temperature lowered through the hydrothermal power generation means 20 and the air injected through the blower (S). It consists of an air circulation system for discharging (reference numerals are omitted), a purification device 100 for purifying the discharged water, and a recycling device R for recycling the discharged air again.

Hereinafter, each component will be described with reference to the drawings.

Referring to FIG. 2, the air circulation system for preventing algae according to the present invention has an air inlet 10 for generating and injecting air at a predetermined pressure through an air generator (not shown) or a blower S.

Hereinafter, the blower (S) will be described.

The air inlet 10 has a space formed therein and has a substantially hexahedral shape, and an air supply part (not shown) passes through one side of the air inlet 10 so that external air is supplied, and the air inlet 10 of An exhaust part (not shown) is formed through the other side so that the air supplied to the inside of the air inlet 10 is exhausted. The blower (S) is connected to the air supply unit and is configured to forcibly supply external air into the air injector (10).

A horizontal air passage 20 is formed that is connected to the air inlet 10 so that the air generated from the blower S can proceed directly in the horizontal direction.

Referring back to FIG. 2 , an air passage 20 for allowing the air mixed through the air inlet 10 to proceed and advance is formed in a long straight shape.

In addition, the air passage 20 is characterized in that the air outlet 25 in the form of an inverted triangle is formed on both sides. A part of the air in the air passage 20 is discharged to the outside through the air discharge unit 25 . As shown, it is made in the shape of an inverted triangle so that it can be discharged at a high speed.

As shown, it is formed in the upper and lower portions of the air passage 20, respectively, to receive water injected through the hydrothermal power generation means 50 and to be transmitted to the outside as if, A horizontal water passage 30 is formed in the form of a pipe. Here, the water passing through the water passage 30 is generated through the hydrothermal power generation means 50, which is generated by dropping the water temperature in the process of generating and generating electricity using the hydrothermal power generation means 50 using the water temperature. It is characterized in that it is possible to prevent stratification in advance and prevent algal blooms by using low-temperature water.

Hereinafter, the hydrothermal power generation means 50 will be described with reference to FIG. 3 .

As shown, the hydrothermal power generation means 50 is installed in the floating body (C) in a configuration for generating electric power using the water temperature of the water sucked from the vicinity of the floating body (C). Here, the floating body (C) is a configuration for forming a buoyancy floating on the water, and may be configured in various ways such as a ship, a barge, a floating body. It is assumed that the rectangular-shaped floating body 10 is floating on the water.

Since the hydrothermal power generation means 50 absorbs the thermal energy of water in the process of converting the thermal energy of the water temperature into electrical energy, the temperature of the discharged water Wo is lower than the temperature of the absorbed water Wi. Accordingly, the operation of the hydrothermal power generation means 50 generates electric power necessary for the operation of the present invention and lowers the water temperature, thereby preventing the occurrence of green algae by supplying low-temperature water. Therefore, the water is sprayed at a lower temperature than the surface water, thereby lowering the water temperature to suppress the growth of green algae and the like.

And, the suction pump (P) serves to suck the water discharged from the discharge unit (40) to supply to the hydrothermal power generation means (50). The water sucked from the suction pump (P) is immediately transferred to the hydrothermal power generation means (50) through the suction pipe (11a).

The hydrothermal power generation means 50 that generates power by absorbing such water heat may be configured in various ways, but an example in which a power generation method using an organic rankine cycle is used as the hydrothermal power generation means 50 is shown in FIG. . A detailed description of the organic Rankine cycle method will be omitted since it is a well-known technique.

As shown, the organic Rankine cycle, which is the hydrothermal power generation means 50, includes a preheater 51, an evaporator 52, a superheater 53, a turbine 54, a condenser 55, a tank 56, and a pump (not shown). ) to form a cycle in which the working fluid circulates in the sequence, and to operate the generator 57 with the rotation of the turbine 54 to generate power.

The preheater 51 constituting the organic Rankine cycle as the hydrothermal power generation means 50 is configured to preheat the working fluid in the liquid state by absorbing the water heat of the water Wi sucked through the suction pipe 11a, and the evaporator 52 ) is a configuration for absorbing water heat and generating a liquid working fluid that has passed through the preheater 51 into a gaseous state. The superheater 53 constituting the organic Rankine cycle as the hydrothermal power generation means 50 absorbs water heat and superheats the gaseous working fluid supplied through the evaporator 52 to a superheated gaseous state.

The turbine 54 circulates the superheated gaseous working fluid supplied through the superheater 53 in the direction of the preheater 51 again, and receives the superheated gaseous working fluid and converts it into mechanical energy to drive and the generator 57 is configured to generate electric power by driving the turbine 54 .

Power generated by the generator 57 is stored in a rechargeable battery 58 . The condenser 55 is configured to condense the gaseous working fluid passing through the turbine 54 into a liquid state, and the cooling liquid working fluid condensed through the condenser 55 is stored in the tank 56 . In the organic Rankine cycle, the cooling liquid stored in the tank 56 is pumped by a pump and supplied to the preheater 51 to circulate.

The preheater 51, the evaporator 52, and the superheater 53 constituting the organic Rankine cycle as the hydrothermal power generation means 50 are configured to absorb water heat, and these components are separately supplied with water to absorb the water heat. Although it may be configured, as shown, water Wi sucked through the suction pipe 11a sequentially passes through the superheater 53, the evaporator 52, and the preheater 51 in order to absorb the water heat, and the connection pipe 11b ) is shown as an example.

In this way, the water discharged through the hydrothermal power generation means (50) with a drop in water temperature is directly discharged to the water passage (30). Therefore, it is possible to more effectively prevent algae by supplying high-quality water whose water temperature is lowered in the power generation process at the same time as power generation through the hydrothermal power generation means 50 . In other words, it is possible to eliminate algae by lowering the water temperature to a temperature that is difficult for algae to occur.

In addition, the solid-liquid separation member 45 shown in FIG. 3 is configured to separate and discharge suspended matter such as green algae microorganisms from the water discharged through the hydrothermal power generation means 50 . The water discharged through the hydrothermal power generation means 50 with a drop in water temperature can be directly discharged to the outside, but is configured to remove the algae by separating the suspended matter such as the algae material contained in the water.

As shown, the solid-liquid separation member 45 is disposed between the hydrothermal power generation means 50 and the discharge pipe 11c to separate and remove suspended matter from the water discharged through the connection pipe 11b through the hydrothermal power generation means 50 . Although it is shown connected to, the solid-liquid separation member 45 is connected before the hydrothermal power generation means 50 and may be configured to separate the floating matter from the water Wi sucked into the suction pipe 11a. will be.

Therefore, it is possible to further improve the algae by preventing algae from the water itself flowing into the water passage 30 supplied in the same way as described above.

Referring to FIG. 2 again, the low-temperature water Wo discharged through the discharge pipe 11c is supplied to the upper water passage 30 and the lower water passage 3, respectively.

In addition, water discharge parts 35 are formed on both sides of the upper water passage 30 and the lower water passage 30 to discharge the water therein. In addition, the air passage 20 and the air outlet 25 for discharging the air inside is also formed.

Accordingly, high-quality water is discharged through the water discharge unit 35, and the air discharged through the air discharge unit 25 is combined with the water.

Therefore, as air and water mix, the amount of dissolved oxygen in water (DO: amount of dissolved oxygen in water) increases. Therefore, by mixing air (oxygen) with spring water, it is eutrophicated to improve algal phenomena such as rivers and lakes (lakes and swamps) where algal blooms occur, thereby purifying water quality in a nature-friendly way.

The upper water passage 30 and the lower water passage 30 are respectively extended and formed, so that the water remaining in communication with each other and progressing is collected in one place and discharged to the outside ( 40) is formed.

Green algae can also be improved in the area into which the water discharged to the outside through the discharge part 40 flows.

Hereinafter, a description will be given of the purification device 100 for purifying the water transferred through the discharge unit 40 with the accompanying drawings.

5 is a block diagram of the purification apparatus 100 . As shown, the purification apparatus 100 includes a settling tank 110 , a water storage tank 120 , a reaction tank 130 , a filtration tank 140 , and a stabilization tank 150 .

Water is introduced into the settling tank 110 through the discharge unit 40 . A discharge network 111 for discharging sludge deposited on the floor to the outside is installed in the lower portion of the settling tank 110 . Here, the type of the discharge network 111 may include a sieve, a filter, and the like.

A transfer hole 160 for transferring water from the settling tank 110 to the water storage tank 120 is formed on the upper side of the side wall between the settling tank 110 and the water storage tank 120 .

The water storage tank 120 supplies the water introduced through the transfer hole 160 to the reaction tank 130 by hydraulic pressure. A transfer hole 170 for transferring water from the water storage tank 120 to the reaction tank 130 is formed at a lower portion of the side wall between the water storage tank 120 and the reaction tank 130 .

A biostone layer 131 made of biostone in which microorganisms inhabit is installed in the reaction tank 130 . A discharge screw 132 for discharging pollutants deposited on the floor to the outside is provided at the lower portion of the reaction tank 130, and the air supply device for supplying air to the biostone layer 131 so that the biostone can move. (133) is connected. Here, the thickness of the biostone is preferably 1.5 to 3 cm.

If the thickness of the biostone exceeds 3 cm, even if air is supplied, the movement of the biostone becomes dull and the reaction efficiency decreases. The reaction time for phosphorus or nitrogen components contained in water is short, resulting in poor reaction efficiency.

A transfer hole 180 for transferring water from the reaction tank 130 to the filtering tank 140 is further formed on the upper side of the side wall between the reaction tank 130 and the adjacent filtering tank 140 .

A filter medium layer 141 filled with a filter medium (a porous material used for filtering, sand, gravel, etc.) for filtering suspended matter contained in water is installed inside the filtration tank 140 . At this time, unlike the biostone layer 131 , the filter media layer 141 passes water in a stopped state because there is no supply of air.

A transfer hole 190 for transferring purified water while passing through the filtration tank 140 to the stabilization tank 150 is formed in a lower portion of the side wall between the filtration tank 140 and the neighboring stabilization tank 150 . Meanwhile, the size of the filter material forming the filter material layer 141 is preferably 1 cm or less.

If the size of the filter media exceeds 1 cm, there is a problem in that only large-sized floats are not filtered, but small-sized floats. The stabilization tank 150 passes through the filtration tank 140 and finally fills the purified water and discharges it to the outside.

Hereinafter, a method of purifying water and air using the purifier 100 will be described. First, water discharged through the discharge unit 40 is introduced into the settling tank 110 . The sludge, etc. contained in the introduced water is settling on the floor by its own weight. When the sediment is accumulated in a certain amount, the sediment is discharged to the outside through the discharge network 111 installed at the bottom of the settling tank 110 .

When the settling tank 110 is filled with water above a certain height, the water in the settling tank 110 is transferred to the water storage tank 120 through the transfer hole 160 formed on the upper side wall between the settling tank 110 and the adjacent water storage tank 120 . are transported

The water transferred to the water storage tank 120 is transferred to the reaction tank 130 through the transfer hole 170 formed in the lower part of the side wall between the water storage tank 120 and the reaction tank 130 by water pressure.

The water introduced into the lower part of the reactor 130 rises by the hydraulic pressure and passes through the biostone layer 131 filled with the biostone where microorganisms inhabit. In this process, as air is supplied into the reactor 130 by the air supply device 133 , the biostones in the biostone layer 131 move.

When the biostone is moved, microorganisms living in the biostone are activated to actively react with water, and in the process, nitrogen or phosphorus components contained in the water are efficiently removed. Meanwhile, in the process of purifying the water in the reaction tank 130 , the sediment accumulated in the lower part of the reaction tank 130 is discharged to the outside through the discharge screw 132 installed in the lower part of the reaction tank 130 . Here, the configuration of the discharge screw 132 is also made of a sieve, a filter, etc. similar to the discharge network 111 .

The water from which nitrogen and phosphorus have been removed in the reaction tank 130 is transferred to the filtering tank 140 through the transfer hole 180 formed on the upper side wall between the reaction tank 130 and the filtering tank 140 .

The water flowing into the upper part of the filtration tank 140 passes through the filter media layer 141 filled with the filter media while descending. At this time, the filter medium of the filter medium layer 141 is in a stationary state, and the floating matter contained in the water is filtered by the filter medium.

The water from which suspended matter has been removed from the filtration tank 140 is transferred to the stabilization tank 150 through a transfer hole 190 formed in the lower portion of the side wall between the filtration tank 140 and the stabilization tank 150 . In the stabilization tank 150, the water finally purified in the filtration tank 140 is filled and then discharged to the outside when the water level reaches a certain height or higher.

Therefore, by using the purifier 100 to allow water to pass through the filter media layer 141 filled with the filter media, suspended matter contained in the water can be easily filtered, and the settling tank 110 and the reaction tank 130 . By installing the discharge network 111 and the discharge screw 132 in the lower part of the, the sediment accumulated in the lower part of the settling tank 110 and the reaction tank 130 can be easily discharged to the outside, so that complete purification is possible.

In this way, after purifying the water through the purification device 100, it is discharged to further improve the green algae.

Hereinafter, a description will be given of an apparatus R for processing using the purification apparatus 100 and recycling the exhausted remaining air with the accompanying drawings.

Referring to FIG. 6 , an ozone generator 200 that generates ozone by introducing oxygen in the air that has been purified through the purification device 100 into the inside is formed. The ozone generated by the ozone generator 200 is supplied to the lower end through the backflow preventer 240, and the vacuum pump 230 and the ozone are sucked in ozone and gaseous oxygen, and the suctioned oxygen and ozone are sucked. When the contained oxygen flows into the inside through the backflow preventer 240, the ozone decomposer 250 purifies the ozone contained in oxygen, and when the oxygen purified through the ozonizer 250 flows into the inside, it The compressor 260 is compressed, and the oxygen compressed through the compressor 260 is composed of an oxygen generator 270 that is supplied into the ozone generator 200 together with the newly generated oxygen.

Hereinafter, with reference to FIG. 6 , a method of reusing oxygen in the air remaining after water is purified through the purification device 100 will be described.

Ozone and oxygen in the air remaining after purification through the purification device 100 are supplied to the ozone generator 200 . Then, the ozone and oxygen are transferred to a vacuum pump 230 for vacuum treatment.

The vacuum-treated oxygen containing ozone is directly introduced into the ozone decomposer 250 through the backflow preventer 240 , and ozone contained in the oxygen flowing into the ozone decomposer 250 is purified.

In this way, the oxygen purified through the ozone decomposer 250 is compressed through the compressor 260 as it flows into the inside, and the oxygen compressed through the compressor 260 is newly generated by the oxygen generator 270 . Oxygen is supplied back to the inside of the ozone generator 200 by the amount consumed together with oxygen.

Therefore, during the purification process through the purification device 100, oxygen containing some ozone in the consumed and remaining air may have an oxygen recycling function so that ozone can be purified and processed in the process of passing through the ozone decomposer 250.

In addition, some oxygen purified through the ozone decomposer 250 and oxygen newly generated through the oxygen generator 270 are mixed, and this mixed oxygen is supplied back to the inside of the ozone generator 200, It has an excellent function of allowing oxygen to be recycled.

Those skilled in the art to which the present invention pertains as described above will understand that the present invention may be implemented in other specific forms without changing the technical spirit or essential features of the present invention. Therefore, it should be understood that the above-described embodiments are illustrative and not restrictive.

The scope of the present invention is indicated by the appended claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention. do.
