Abstract
본 발명은 소성한 미세분말 황토의 공중살포에 의한 적조방제 방법 및 장치에 관한 것이다.The present invention relates to a red tide control method and apparatus by air spraying of calcined fine powder loess.
종래의 적조방제 방법 및 이의 장치는 노천에서 발굴한 생황토를 작업선에 적재하여 현장에 가서 삽 등의 수공구를 이용하여 해수중에 살포하였던 관계로 작업성이 저조하여 급격히 확산하고 있는 적조현상을 제때에 방제할 수 없는 결점이 있고 또한 이와 같이 하여 살포된 생황토는 모래, 세석등의 이물질이 함유되어 있고 덩어리가 많은 관계로 수중분해가 잘되지않고 대신 침강속도가 빨라 방제효율이 저조할뿐만 아니라 해저에 퇴적되어진 다음에는 저서생물의 생태에 나쁜 영향을 미치게 하는 폐단이 있었던 것이다.The conventional red tide control method and its device are loaded with fresh yellow soil excaved from the open air on the work line and sprayed in the seawater by using hand tools such as shovels. There is a defect that can not be controlled in this way, and the raw yellow soil sprayed in this way contains foreign substances such as sand and fine stone, and due to the mass, it is difficult to disintegrate in the water. After being deposited on the ocean floor, there was a ruin that would adversely affect the ecology of benthic creatures.
본 발명은 이상의 문제점을 해결하고자 발명한 것으로 이의 발명요지는 터널킬른(가마)을 이용하여 황토(적토)를 850∼900℃로 가열한후 분쇄기를 이용하여 입자의 지름이 10μ(미크론)이하가 되도록 분쇄한후 여기에 유기물분해 박테리아(험기성, 호기성, 방성균 등)을 0.1%중량비로 혼합한 분말황토(6)를 얻고 이를 선박이나 항공기(헬리곱터)에 장치된 살포기몸체(1)의 호퍼(3)에 투입하여 조절구(3')를 이용하여 적당량이 몸체(1)내로 유입되게한 다음 휀엔진(4)을 가동시키면 이의 높은 풍압과 풍력에 의해 몸체(1)내에 유입된 분말황토(6)는 분사구(5)를 통해 30∼45°범위의 부채꼴 각도로 연막처럼 광범위(반지름 200m이상)하게 분사되어 해수면 위에 낙하하게 되고 이와 같이 낙하된 분말황토(6)가 해수중에 침강될시는 10μ(미크론)이하의 미입자이므로 비중이 가볍기 때문에 침강속도는 느린 대신 이의 확산속도가 빠르므로 적조확산 현상방제에 신속히 대처할수 있게한 것이다.The present invention has been invented to solve the above problems, and the present invention is to use a tunnel kiln (kiln) to heat the loess (red soil) to 850 ~ 900 ℃ and using a grinder has a particle diameter of less than 10μ (micron) After pulverizing as much as possible, powder loess (6) obtained by mixing organic hydrolysis bacteria (aerobic, aerobic, antibacterial, etc.) in a 0.1% weight ratio is obtained, and the hopper of the body (1) of the spreader body (1) installed on a ship or an aircraft (helicopter). 3) After the proper amount is introduced into the body 1 by using the control port 3 'and the engine 4 is operated, the powder loess introduced into the body 1 by its high wind pressure and wind power ( 6) is sprayed in a wide range (more than 200m radius) like a smoke screen at a fan-shaped angle of 30 ~ 45 ° through the injection hole (5) falls on the sea surface and when the powder ocher (6) dropped in this way is settled in the sea water Specific particles less than 10μ (micron) Since it is light, the sedimentation rate is slow, but its diffusion rate is fast, so that it can cope with the red tide diffusion phenomenon quickly.
Description
본 발명은 소성미세분말 황토의 공중살포에 의한 적조(赤潮) 방제방법 및 장치에 관한 것이다.The present invention relates to a method and apparatus for controlling red tide by air spraying of calcined fine powder loess.
적조는 해수속에서 1종이상의 플랑크톤이 폭발적으로 증식하여 물이 덩어리 또는 띠모양으로 적갈색이나 분홍색으로 변하는 현상 또는 물속의 인·질소가 증대하거나 그밖의 원인이 복합하여 생기는 것으로 이는 담수가 유입하는 연안에서 많이 생기는 것이며 플랑크톤의 급격한 증식과 사멸분해에 의해 산소가 대량으로 소비되어 무산소의 수괴가 생겨서 유해한 분해산물이 축적되어 어패류에 큰 피해를 주게 되는 것은 이미 알려진 사실로서 이와 같은 현상을 방제하는데는 황토가 가장 효과적인 것임이 학계의 연구 결과 알려진 사실인 것이다.Red tide is a phenomenon in which one or more planktons explode in seawater, causing water to turn reddish brown or pink in lumps or bands, or an increase in phosphorus and nitrogen in water or a combination of other causes. It is a known fact that large amounts of oxygen are consumed by rapid proliferation and killing of plankton, and anoxic lumps are generated, and harmful decomposition products accumulate and cause great damage to fish and shellfish. Is the most effective of the academic findings.
그러나 종래의 황토를 이용한 적조방제방법은 단순히 노천에서 채굴한 생황토를 작업선에 적재하여 적조발생현장에 싣고 가서 삽 등의 수공구를 이용하여 해층에 시포하는 형식으로 방제작업을 실시하였기 때문에 작업성이 매우 저조하여 급격히 확산되고 있는 적조의 확산을 방지할수 없고 또한 황토가 골고루 해수층에 시포되지 않아 방제효율이 저조할뿐만 아니라 이와 같은 생황토 중에는 세석, 모래등 적조방제와는 직접 관계가 없는 물질이 포함되고 있으며 때에 따라서는 이종광물이 섞여있어 되려 적조현상을 조장하는 폐단이 있었던 것이다.However, in the conventional red tide control method using yellow loess, it is easy to load the raw yellow soil mined from the open air on the working ship, load it on the red tide occurrence site, and use the hand tools such as shovel to control the work in the sea layer. This very low and rapidly spreading red tide can not be prevented, and the yellow soil is not evenly distributed in the seawater, so the control efficiency is low, and among such raw loess, it is not directly related to red tide control such as fine stone and sand. It is included and sometimes heterogeneous minerals are mixed to promote red tide phenomenon.
본 발명은 이상의 문제점을 해결하고자 발명한 것으로 이의 발명요지는 터널킬른(가마)을 이용하여 통상의 황토(적토)를 850∼900℃로 가열 소성한후 분쇄기를 이용하여 입자의 지름이 10μ(미크론) 이하가 되도록 분쇄한후 여기에 유기물분해 박테리아(험기성, 호기성, 방선균 등)을 0.1%중량비로 혼합한후 작업선에 설치된 분말살포기 또는 항공기에 설치된 분말살포기를 이용하여 넓은 지역을 빠른 시간내에 방제하므로서 적조의 확산을 방지할수 있게한 것이다.The present invention has been invented to solve the above problems, the present invention is a tunnel kiln (kiln) by heating the ordinary loess (red soil) to 850 ~ 900 ℃ by heating and baking using a grinder 10μ (micron diameter) Pulverize to less than or equal to 0.1% by weight of organic hydrolysis bacteria (aerobic, aerobic, actinomycetes etc.) and then use a powder sprayer installed on a working ship or a powder sprayer installed on an aircraft in a short time. By controlling, it is possible to prevent the spread of red tide.

이를 도면에 의거 상세히 설명하면 다음과 같다.This will be described in detail based on the drawings.
제 1도는 본 발명에서 채택한 살포기몸체(1)로서 하부에는 받침대(2)가 형성되고 상부에는 조절구(3')가 있는 호파(3)가 설치되며 살포기몸체(1)의 앞측에는 분사구(5)가 형성되고 후측에는 휀엔진(휀모터)(4)이 설치되어진 것으로 이를 실시할시는 통상의 작업선(7) 선미 또는 선두 그리고 헬리곱터와 같은 항공기에 살포기몸체(1)를 1∼3대 동시 설치하면 되는 것이다.1 is a sprayer body (1) adopted in the present invention as a base (2) is formed at the bottom and the hopper (3) is provided with a control opening (3 ') at the top and the sprayer (5) in front of the sprayer body (1) ) And a rear engine (4) is installed on the rear side. When this is done, one to three sprayer bodies (1) are mounted on an aircraft such as a normal working vessel (7) or a stern or head and a helicopter. You can install it at the same time.
이의 실시에 있어 작업선을 이용한 경우의 실시예를 설명하면 다음과 같다.An embodiment in the case of using a working ship in the implementation thereof will be described below.
실시 제 1공정 - 통상의 터널킬른(가마)을 이용하여 통상의 황토(적토)를 850∼900℃로 가열 소성한후 분쇄기를 이용하여 입자의 지름이 10μ(미크론) 이하가 되도록 분쇄한후 여기에 유기물분해 박테리아(험기성, 호기성, 방성균 등)을 0.1%중량비로 혼합한 분말을 얻는다.Step 1-After heating and baking the ordinary loess (red soil) at 850 ~ 900 ℃ using a normal tunnel kiln, using a pulverizer, the particle diameter is pulverized to 10μ (micron) or less, and then To a powder obtained by mixing organic decomposition bacteria (aerobic, aerobic, antibacterial, etc.) in a 0.1% weight ratio.
실시 제 2공정 - 통상의 작업선(7)(10t)의 후미(또는 선두)에 살포기 몸체(1)를 3대 장착한후 살포기몸체(1)의 상부에 형성된 호파(3)에 실시 제 1공정에서 얻어진 분말황토(6)를 가득 채운다.Implementation 2nd step-After attaching three spreader bodies 1 to the tail (or head) of the normal working line 7 (10t), it implements on the hopper 3 formed in the upper part of the spreader body 1. The powder loess 6 obtained in the process is filled up.
실시 제 3공정 - 실시 제 2공정의 준비가 완료된후 작업선(7)을 시속 5노트로 항진시켜 제 2도 예시와 같이 공중(15∼30℃의 각도) 살포를 실시한바 반경 250m의 범위내에서 무화(霧化)현상이 생긴후 해상수면에 고루 침하되어졌고 해수에 침투시는 침강속도가 늦고 대신 확산속도는 빨라서 해수 중에 확산되고 있는 적조띠(또는 덩어리)에 침투하여 적조덩어리 또는 띠를 분해시켜 청정해수가 되게 하였다. 이때 호퍼(3)에 투입된 분말황토(6)는 조절구(3')의 조절에 의해 일정량 하강되면 휀엔진(4)에 의해 분사구(5)로 분사될시는 마치 방제용 연무기와 같이 상당한 압력을 갖고 분사하였으며 이때 풍량과 풍압을 측정한바 풍량은 20m3/min이상이었고 풍압은 7O∼8OmmHg였으며 호퍼(3)내에 투입된 분말황토가 소모될시는 계속 공급한바 장시간(3시간) 살포작업을 계속 할 수 있었다.Step 3-After the preparation of Step 2 is completed, the working ship 7 is advanced to 5 knots per hour and air (15 to 30 ° C) is sprayed as shown in FIG. After the atomization occurred in the sea, it was settled evenly on the sea surface. When it penetrated into the seawater, the sedimentation rate was slow. It was decomposed into clean seawater. At this time, when the powder loess 6 injected into the hopper 3 is lowered by a certain amount by the adjustment of the adjusting device 3 ', when the jet is injected into the injection hole 5 by the engine 4, a considerable pressure, such as a nebulizer for control, is applied. At this time, the air volume and the air pressure were measured. The air flow was more than 20m 3 / min and the air pressure was 7 ~ 80mmHg. When the powder loess injected into the hopper 3 was consumed, it was supplied continuously for a long time (3 hours). Could.
그리고 생황토를 해수에 바로 뿌릴 때는 해저에 황토 퇴적층이 생겨저서 생물에 피해를 주는 현상이 있었으나 본 발명은 해저 퇴적하는 양이 거의 없으므로 저서생물에 대한 피해가 없었다.And when sprinkling raw ocher directly in seawater, there was a phenomenon in which the ocher sediment layer was formed on the seabed to damage living organisms, and thus the present invention had no damage to benthic organisms because there was almost no amount of sediment deposited on the seabed.
별도실시예 - 이는 실시예 1의 경우인 작업선 대신으로 통상의 헬리곱타 항공기(8)를 이용하여 제 3도에 예시한바와 같이 저공저속 공중살포 작업을 실시한바 작업선을 이용한 공중살포에 못지않게 좋은 성과가 있었다.Separate embodiment-This is similar to the air spray using the low air low speed air spraying operation as illustrated in FIG. 3 using the conventional helicopter helicopter 8 instead of the working ship which is the case of the first embodiment. Not good performance.
이상과 같이 본 발명은 바다에서 발생하여 급격히 확산되고 있는 적조현상을 방제함에 있어 이를 터널킬론(가마)을 이용하여 850∼900℃로 소성한후 분쇄기에 투입하여 이의 입자지름이 10μ(미크론)이하가 되도록 분쇄한 분말황토(6)를 얻고 여기에 유기물분해 박테리아(험기성, 호기성, 방성균)을 0.1%중량비로 혼합한 것을 살포기몸체(1)를 이용하여 살포함에 있어 살포기몸체(1)를 통상의 작업선(7) 또는 헬리곱터와 같은 항공기(8)에 장착하여 공중살포 형식으로 실시할수 있게 하므로서 적조확산 현상 방제에 신속히 대처할수 있고 또한 분말황토(6)가 해수중에 침강될시는 이의 침강속도는 늦고 대신 확산속도는 빠르게 이루어지게 하였기 때문에 방제효율이 높을뿐만 아니라 분말황토의 해저퇴적 현상이 거의 없어 저서생물 보호에도 크게 기여할수 있는 것이다.As described above, in the present invention, in controlling the red tide phenomenon which is rapidly spreading in the sea, it is fired at 850-900 ° C. using a tunnel kilon and then put into a grinder to have a particle diameter of 10 μm or less. The powder loess (6) pulverized to obtain a mixture of organic hydrolysis bacteria (aerobic, aerobic, antibacterial) in a 0.1% weight ratio by using the duster body (1) in the spreader body (1) It can be mounted on a normal working ship (7) or an aircraft (8), such as a helicopter, so that it can be carried out in the air spray type, and can quickly cope with the control of the red tide diffusion phenomenon, and when the powder ocher (6) is settled in seawater, its sedimentation is performed. It is not only high control efficiency but also low sedimentary phenomenon of powder loess because it is slow and diffusion speed is made fast, so it can contribute greatly to benthos protection. Will.
