Description

Algae sweeper ship for prevention and rapid removal of algae}

The present invention relates to algae removal vessels for the prevention and rapid removal of algae, and more particularly, it is possible to quickly and efficiently remove algae generated in eutrophiced lakes or streams and prevent their occurrence in advance. The present invention relates to algae removal vessels for the prevention and rapid removal of algae that can contribute to the health of the people by securing high quality water resources and creating comfortable and comfortable hydrophilic spaces.

Water pollution in rivers and lakes is increasing due to industrial development, population increase and concentration, increase of pollutant emission due to improvement of living standard, and increase of fertilizer use to improve agricultural productivity. The green algae caused by this cause the appeal of the appeal and the hydrophilic environment.

In addition, the generated green algae causes filter paper blockage in the water purification process, and when the green algae are severe, toxic substances such as microcystin are also concerned. This is urgent.

Techniques for removing algae can be divided into methods of blocking inflows into rivers and lakes, and methods of minimizing and removing the generation of contaminants in the lakes.

The most direct and best way to control algae is to block the flow of nutrients. However, it can be reduced to some extent from the point source, but it is not practical to block non-point pollutants coming from roads, farmland, forests, etc.

Minimizing the occurrence of green algae in the appeal involves blocking the light that affects the growth of algae, and injecting chemicals (coagulants, loess, algae, etc.) to aggregate phosphorus that acts as a nutrient for algae and algae growth. To settle to the bottom of the lake, to control algae growth through aquatic organisms, to dredge the sediment on the bottom of the lake, and to remove algae by destroying the tissue of the algae using ultrasound. have.

However, these methods cause the following problems.

The method of reducing pollutants entering the lake has not been suggested to deal with scattered nonpoint pollutants, and the method of blocking light in the lake can be done in small ponds. Inappropriate for appeal, sedimentation with flocculants or loess is likely to re-elute nutrients if the sediment is not removed out of the appeal, and aquatic and ultrasonic methods also affect other organisms. There are disadvantages that can have. The method of dredging the sediment existing at the bottom of the appeal is disadvantageous in that the sediment floating and enormous budget is required.

Meanwhile, the currently developed algae removal technology has developed and commercialized a method of destroying air bubbles in algae cells using an ultrasonic algae removal device (Aquasonic) for underwater algae removal by LG Sonic (USA), but the device is expensive. And it takes a long time to remove the algae, there is a disadvantage that the dead algae is precipitated in the appeal can be re-eluted in the algae phosphorus (P) in the long term.

In domestic technology, chemicals (coagulants, loess, algae, etc.) are added to aggregate the phosphorus, which acts as a nutrient for algae and algae growth, to precipitate on the bottom of the lake, and to precipitate by flocculation / sedimentation in the lake. Technology is mainly applied, in which case the algae and sediment sludge settled at the bottom of the appeal is an anaerobic environment, the phosphorus (P) is re-dissolved to accelerate eutrophication.

Alternatively, in order to improve the water quality of the appeal, a method of circulating the water by introducing the water in the appeal to a treatment device outside the appeal is applied, but it takes a long time, and there is a disadvantage in that economic efficiency is high due to the high power demand for water circulation.

Considering these points, in order to solve the problem of algae in the eutrophication, it should not disturb the ecosystem in the appeal, and it should be able to remove algae quickly and suppress the algae in the long term. Economical technology development is needed.

As shown in FIGS. 1 and 2, the bubble generating / injecting unit 120 is provided at the front end portion 110a of the hull 110 and generates bubbles to inject bubbles into the appeal. At this time, the bubble may be a micro (nano) or (nano) bubble (bubble).

Micro or nano bubbles refer to ultra-fine bubbles that are not visible to the eye in sizes of several micrometers or less, such as 50 micrometers or less. Normal bubbles (bubbles, droplets) present in water are elevated to the surface of the water and then destroyed at the surface of the water, but micro or nano bubbles are known to dissipate under pressure while generating various energy. have. Therefore, the micro or nano bubbles are provided in the washing tank to improve the washing power, to clean the water to double the effect of the bath, to clean the water quality, or as an auxiliary use for removing algae as in this embodiment. Can be.

Looking at the bubble generation / input unit 120 in detail, as shown in Figures 4 to 6, the bubble generating unit 121 for generating bubbles to be injected into the appeal and the bubble generating unit 121 on one side Bubble supply line 122 is connected to the bubble generated in the bubble generating unit 121 into the appeal and the water supply line is connected to the other side of the bubble generating unit 121 to supply water to the bubble generating unit 121 123 and a pressure pump 124 provided on the water supply line 123 to pressurize the water supplied to the bubble generator 121 along the water supply line 123.

One side of the water supply line 123 is provided with a circulation pump 125 for circulating water (appeal water) in the appeal, and a storage tank 126 for storing water circulated by the circulation pump 125. The water supply line 123 may connect the storage tank 126 and the pressure pump 124.

On the bubble input line 122 and the water supply line 123 may be provided with a plurality of valves that can be opened and closed as needed, as shown in Figure 4, unlike the water supply line 123 bubble input line 122 Up and down movement is possible, that is, may be provided as a corrugated flexible pipe (flexible pipe).

Thus, when the bubble input line 122 is provided with a corrugated flexible pipe, the bubble can be evenly supplied to a wider area from the low area to the high area in the appeal and thus can be adjusted according to the water level. The bubble input line 122 may be provided with only a part of the corrugated flexible pipe as shown in the drawing, or may be provided with the whole of the corrugated flexible pipe. The bubble injection nozzle 127 may be connected to an end of the bubble input line 122.

As shown in FIGS. 1, 2, 5, and 6, the coagulant input unit 130 is disposed adjacent to the bubble generation / injection unit 120, and serves to inject coagulant into a region into which the bubble is injected. do.

A flocculant is a substance which coagulates and precipitates the inorganic substance and organic substance contained in an appeal simultaneously. Inorganic salts are called coagulants and synthetic polymers may be called coagulants. Coagulation conditions can be improved by adding cations, anions, and coagulants for metal salts and natural minerals.

The coagulant injecting unit 130 may include a coagulant injecting line 131 forming a line into which the coagulant is injected into the appeal, and a coagulant conveying pump 132 connected to the coagulant injecting line 131 to transfer the coagulant. .

The flocculant input line 131 may also be provided as a corrugated flexible pipe, which is capable of vertically moving, similarly to the bubble input line 122.

Thus, when the coagulant inlet line 131 is provided with a corrugated flexible pipe, coagulant can be evenly distributed from the low area to the high area in the appeal and even wider area, so that it is possible to cope with the water level. It can increase. The coagulant input line 131 may be provided with only a part of the corrugated flexible pipe as shown in the drawing, or may be provided with the whole of the corrugated flexible pipe.

As shown in FIG. 6, both the bubble input line 122 and the flocculant input line 131, which may be provided as corrugated flexible pipes, may be provided in plural numbers, and may be provided by a plurality of guide bars 135. The movement can be guided integrally. The vertical movement motor 136 may be connected to the guide bar 135. In addition, a depth measuring sensor 137 may be disposed on the lower bracket B connecting the lower end of the guide bar 135. The vertical movement motor 136 may be controlled based on the action of the depth measurement sensor 137.

Accordingly, when the vertical movement motor 136 is operated to guide the guide bar 135 up and down, the bubble input line 122 and the coagulant input line 131 are both moved up and down while the bubble and the coagulant are moved in the space. Evenly and widely can be injected.

2, 11 and 12, the admixture unit 140 is provided in the hull 110 of the bubble and the region in which the flocculant is injected, the bubble and flocculant introduced into the appeal is a particulate matter dissolved in the particulate matter. It is made of sludge to injure. The sludge at this time may include total phosphorus (T-P), algae, suspended solids (SS) and the like.

In this embodiment, the mixing unit 140 may be applied to the non-powered mixing unit 140 having the structure of FIG. 12, for example.

That is, the non-powered mixing unit 140 may be formed of a plurality of mixing guide plates 141 which are stacked, and the plurality of through holes 141a and the plurality of through holes (141a) through which the treated water floated upwardly pass through the mixed guide plate plates. A plurality of diaphragms 141b positioned above the 141a to branch the treated water are formed. The plurality of through holes 141a and the plurality of diaphragms 141b are alternately formed over the entire area of the mixing guide plate 141.

Therefore, the treatment water floating in the A direction through the through hole 141a of the mixing guide plate 141 located at the lower portion is the vertex region of the V-shaped diaphragm 141b installed in the other mixing guide plate 141 disposed above the vertical direction. After hitting the diaphragm 141b at the phosphorus B and split into two branches C1 and C2, the diaphragm is raised in the direction D1 and D2 through each of the through holes 141a located at both sides of the diaphragm 141b. Of course, through the side plate (141c) is also branched through the through-holes (141b) of the front and rear of the partition 141b to induce uniform mixing of the treated water. The treated water raised again through the through holes 141a again collides with the diaphragm 141b of the mixing guide plate 141 disposed vertically upward, and then splits back and forth, left and right again and then through the through holes 141a around the through holes 141a. As the process is repeated, it is possible to induce uniform mixing of the flocculant.

In the case of having such a structure, the flocculant and the bubble provided in the direction of the arrow in FIG. 12 are mixed well while passing through the plurality of mixing guide plates 141 by the traveling speed of the hull 110 and the bubble feeding rate, and the dissolved material. Can grow into particulate sludge and float.

In the case of the non-powered mixing unit 140, there is an advantage that no power source is required, but in some cases, a power mixing unit such as an agitator may be applied, and such matters should also belong to the scope of the present invention.

1 and 2, the scraper unit 150 serves to collect one side while moving the sludge floating by the non-powered mixing unit 140.

The scraper unit 150, the motor 151, the drive shaft 152 connected to the motor 151, and the longitudinally spaced and parallel to the drive shaft 152 along the direction in which the hull 110 is driven. The chain 154 coupled to the coaxial 153, the drive shaft 152 and the driven shaft 153 in the form of a closed loop and rotated, and a plurality of moving pieces coupled to the chain 154 and moved along the chain 154 155 and a scraper 156 coupled to the moving piece 155 and moved together with the moving piece 155 to move the sludge to a large surface area and collect the sludge into the sludge storage tank 160.

Accordingly, when the driving shaft 152 is rotated by the motor 151, the driven shaft 153 is also rotated by the chain 154, and the scrapers 156 along the chain 154 together with the moving piece 155. While moving, the sludge floating by the non-powered mixing unit 140 is moved to the sludge storage tank 160. Therefore, the sludge can be collected in the sludge storage tank 160, the collected sludge is disposed of.

The sludge storage tank 160 is a place where the sludge collected by the scraper unit 150 is stored, as shown in FIGS. 2, 3, and 11.

And the floating unit 170, as shown in Figure 1, 3 and 9, is arranged along the longitudinal direction of the hull 110 on both sides of the hull 110 serves to float the hull 110 to the water surface. do.

In this structure, the sludge storage tank 160 is disposed along the inner edge of the pair of floating unit 170, the front and rear surfaces are lower than the water level and the side is disposed higher than the water level. As a result, a flow path through which water can pass may be formed inside the algae removal line. Accordingly, water and sludge passing through the non-powered mixing unit 140 installed at the front end portion 110a may be lifted to form a scraper unit ( While moving by 150 may be collected in the sludge storage tank (160).

As shown in FIGS. 7 and 8, the water level adjusting unit 180 is provided in the hull 110 to adjust the water level of the sludge storage tank 160.

For example, the water level of the sludge reservoir 160 may be adjusted by the level control unit 180, which may be applied to the cylinder. That is, when the amount of sludge removed is large, the side of the sludge reservoir may be lower than the water level due to the weight of the sludge reservoir. Although lowered, the efficiency of the scraper unit 150 may be lowered, but by applying the present level control unit 180 it is possible to maintain a constant level of the sludge reservoir. The water level adjusting unit 180 may be disposed at four corner regions of the hull 110, respectively.

The power generating unit 190 serves to generate power for driving the hull 110, as shown in FIGS. 7 to 10.

The power generating unit 190 includes a driving motor 191, a reduction gear 192 directly connected to the driving motor 191, a driving aberration 193 connected to the reduction gear 192, and traveling It may include a safety cover 194 covering and covering the outside of the aberration 193. The power generating unit 190 may be provided symmetrically on both sides of the hull 110.

The operation of the algae removal line having such a configuration will be briefly described.

The algae removal line of this embodiment travels from right to left with reference to FIGS. 1 and 2, and the water flows from left to right. Sludge may finally collect in the sludge reservoir 160 based on the flow of water.

That is, when the algae removal line is driven and the bubbles from the bubble generation / injection unit 120 and the flocculant from the flocculant input unit 130 are introduced into the appeal, the bubbles and the flocculant pass through the non-powered mixing unit 140 and are in the appeal. It combines with sludge such as nitrogen, phosphorus, and other suspended solids (SS) to grow as an ion carrier, causing sludge in the appeal.

Meanwhile, when the motor 151 is operated, the scrapers 156 are moved along the chain 154 together with the moving piece 155 to move the sludge injured by the non-motor mixing unit 140 to the sludge storage tank 160. .

Therefore, the sludge can be collected in the sludge storage tank 160, the collected sludge is disposed of.

According to this embodiment having such a structure and operation, it is possible to quickly and efficiently remove algae generated in eutrophiced appeal or rivers to secure high quality water resources and create comfortable and comfortable hydrophilic space to contribute to national health. It becomes possible.

In addition, the algae removal line of the present invention has the advantage of improving the water quality while actively and actively coping with the occurrence of algae in the appeal, unlike the existing passive treatment technology.

In other words, the existing algae removal technology has been mainly applied to sedimentation using flocculation / sedimentation in the appeal, in which case the algae and sediment sludge settled at the bottom of the appeal is an anaerobic environment, the phosphorus (P) Elution has the disadvantage of accelerating eutrophication. In addition, in order to improve the water quality of the appeal is applied to the method of circulating the water by introducing the water in the appeal to the processing device outside the appeal, it takes a long processing time, there is a disadvantage in the economic efficiency because the power demand for water circulation is high. However, the algae removal line of the present invention, unlike the existing technology, because it can remove the algae generated in the appeal at the same time to improve the water quality is also excellent water quality improvement effect.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Therefore, such modifications or variations will have to be belong to the claims of the present invention.
