The loess duster for red tide control according to the present invention is loaded on a dedicated line or barge line (200). The loess duster for red tide control according to the present invention comprises: a seawater intake pump (1) for collecting seawater in connection with the vacuum tank (11); An ocher loading and suspending tank 12 for spraying the seawater taken up by the seawater withdrawal pump 1 at high speed by means of a high-speed seawater injection moving nozzle 8 to a stack of loess, to produce loess as a loess slurry 42; A colloidal loess water producing tank 13 for producing the colloid loess water 46 by the colloid loess water agitation pump 3, the loess suspension 42 produced in the loess-loading and suspension production tank 12; The colloidal loess soil water 46 prepared in the colloidal loess water tank 13 is diluted with the colloidal loess water dilution pump 3 to dilute the colloidal loess water so that the colloidal loess water 47 is diluted (14); And a high-speed spraying pump 6 or an underwater injection pump 7 for spraying the colloidal yellow soil water 47 produced in the colloidal yellow soil water dilution tank 14 in a large amount, at a high pressure, and at a high speed.

When the seawater is injected at a high speed into the loess soil by means of the high-speed seawater injection moving nozzle 8, a gravel is left on the wire mesh 45 and the wire mesh 45), the yellow clay suspension 42 is collected and stored. The colloidal yellow soil water dilution tank (14) can be divided into two tanks.

The method for spraying yellow clay produced by the red soil duster for red tide control according to the present invention is characterized in that the method for spraying yellow clay according to the present invention is a method for spraying yellow clay, which comprises a seawater receiving step (S1) for collecting seawater in connection with a vacuum tank (11) ; The seawater collected by the seawater collection step S1 is rapidly sprayed on the loess pile loaded on the loess material accumulation and suspension production tank 12 by the high-speed seawater injection moving nozzle 8 to transfer the loess to the loess suspension 42 A manufacturing step (S2) of an ocher suspension to be produced; A colloidal lozenge counting step (S3) of transferring the loess loaf suspension (42) to a colloidal loamy water producing tank (13) to produce colloidal loamy loamy water (46) by a colloidal loamy water stirring pump (3);

The colloidal loess soil 46 is transferred to the colloid loess water dilution tank 14 and the colloidal loess soil 46 is crushed and diluted by the colloidal loess water dilution pump 5 to prepare the final colloidal loess soil 47 Colloidal yellow soil water dilution step (S4); And a colloidal yellow soil water spraying step (step S8) of spraying the colloidal yellow soil water 47 produced by the colloidal yellow soil water dilution step S4 by a high-speed spraying pump 6 or an underwater spraying pump 7 at a high- (S5); And a control unit.

In the colloidal loess soil water producing step S3, the nozzle connected to the colloidal loess water agitation pump 3 is installed at an angle of 5 ° upward from the lower side of the stirring tank so that the seawater is injected strongly in the lateral direction, A return current is generated.

In the colloidal yellow soil water dilution step (S4), small granular sand that has not been filtered in the colloidal yellow oily water production step (S3) and particles having a size of 50 탆 or more that have not been colloidized are removed by the colloidal oily soil water dilution pump By pulverizing and diluting by the electric current, small sands which are clogged by the injection pump or the injection nozzle are filtered to produce the final colloidal loamy water 47.

The present invention improves the technique of spraying loess to the sea when the loess is sprayed to the sea where the blooming occurs, and it supplies the seawater by the pump installed in the tank, And the loess is pulverized and diluted with stirring to finely distribute loess particles and then spray the loess. The method and apparatus will be described in the following order.

(1) The present invention will be described in its entirety. It is important to make colloid-state loess water and spray it by aiming at the red tide from the injection nozzle through the pump and piping. In this step, loess is mixed with seawater first, and the suspension is injected strongly into the circulating tank through the circulating colloid circular tank to inject seawater into the circulating tank. Thus, the loess suspension is mixed with the strong colloidal loess Make a number. In the first colloidal state, there is a small granular sand that does not have red tide relieving effect, and a 50 ㎛ or more loess grains that are not colloidized. It can filter out sand that may cause clogging and spray only colloidal yellow clay. The rotating current in the tank regulates the flow rate of the influent water flowing from the pump, so that the sand contained in the loess water is submerged to the bottom of the tank. In other words, only the colloidized loess that floats above the tank pumps or overflows to the next step.

(2) A method of grinding loess and a device therefor will be described. The loess spreader is loaded on a dedicated line or a barge as shown in Figs. 1 and 2. In order to crush and stir the loess, seawater is taken with a seawater intake pump (1). The pump (1) acquires seawater in connection with the vacuum tank (11). First, the vacuum tank 11 is filled with water to maintain the vacuum pressure, and then, when the pump sucks the seawater in the vacuum tank, the seawater is taken in the vacuum tank by the negative pressure in the vacuum tank. The seawater is collected at a high speed using a high-speed seawater injection nozzle (8) on the ocher pile (43) of the ocher loading tank as shown in Fig. VI [K] To produce an oily suspension (42) in the form of a primary suspension, and then the oily suspension is fed to the next step. The arrow 44 indicates that the high-speed seawater injection moving nozzle 8 is sprayed while moving forward and backward.

(3) A method for producing a yellow loess suspension and a device therefor will be described. A large amount of loess can be loaded in the loess loading and suspension manufacturing tank 12 and a wire net 45 of a certain size is installed in the lower part of the tank so that seawater is sprayed by the nozzle at high speed from the tank, A gravel or the like remains on the upper part of the wire net while the ocher suspension 42 flows to the colloid loam tank 13 by the transfer pump 2 in the direction of the ocher suspension transfer pump. The tank 12 for producing the ocher loading and suspension is capable of causing problems in the benthic ecosystem, separating the gravels which have no red tide remedy effect and can not be sprayed.

The high-speed seawater injection moving nozzle 8 is installed on the loess pile 43 loaded in the clay loft and suspension manufacturing tank 12 as shown in Figs. 1, 2, and 6 to spray seawater at high speed onto the loess soil, Etc., and a suspension.

The loess slurry transfer pump (2) transfers the loess suspension from the loess loading and suspension tanks to the loess colloid stirring tank, which is the next step. The loess suspension also contains sand and small gravel.

(4) A method of manufacturing colloidal yellow soil water and its apparatus will be described. The colloidal loess water producing tank 13 is a circular type, and the seaweed supplied to the suspension introduced into the stirring tank by the suspension conveying pump 2 through the pump in the vacuum tank is connected to the colloidal loess water agitation pump 3 by the stirring A rising vortex gravity method is used in which a rising current (refer to FIG. 7) is generated in the tank when it is installed at an angle of about 5 degrees from the lower side of the tank at an angle of about 5 degrees and is strongly jetted in the lateral direction. By this rising current, the loess particles are finely crushed second and separated into colloidal loess with a particle structure of red tide creature and coarse particles such as sand. The colloid loess water is overflowed to the colloidal loess water transfer pump 4 or the transfer pipe 21 and transferred to the colloidal loess water dilution tank 14 which is the next step and the grains which have fallen downward by the gravity in the stirring tank Of the loess is discharged to a certain extent through the outlet provided at the bottom.

The rising vortex gravity method in the loess dilution mixing tank and the loess colloid stirring tank is a method in which a hole is drilled in the lower part of the tank from the outside of the tank as shown in FIG. 5, When seawater is introduced, the water is rotated, and upward rotation or vortex is produced by the inclination angle toward the top.

As the ascending flow is formed by the upward swirling method like this, the number of the loess that is formed by the force is increased by a certain amount of grain size, and then it is conveyed by the overflow or the pump to the next stage, The grains of the grains of the gravitational grains sink down to the bottom. In other words, when the yellow loess water is kept in the tank and the time passes, all the grains of grains go down and only the water is left in the upper part. However, when the water is rotated and stirred, grains having gravity larger than the rising energy sink down, The number of the loess is increased. For red tide relief, these colloidal loess water is used.

As the number of pump revolutions increases and the pressure increases to increase the flow of seawater flowing into the tank, the rising energy increases and a certain number of grains are included in the loess water. Therefore, it is necessary to determine the appropriate number of rotations You need to adjust. If there is a problem with the operation of spraying the loess water, it is necessary to open the lid of the drain pipe installed at the bottom of the lower tank, and to discharge them. In order to prevent clogging by sand and pearl loess in each piping, the flow rate of the pump is rapidly removed. However, in order to eliminate these loess and pearlite loess that can accumulate in the stagnant flow in some piping, It can be removed by leaving a little slope low. Most of the metal materials used in seawater use stainless steel.

(5) Final (Secondary) A method of manufacturing colloidal yellow soil water and its apparatus will be described. The colloidal loess water dilution pump 5, which is another pump installed at the lower part, stirs the loess water while making a rising current in the dilution mixing tank like the colloidal loess water stirring pump 3 of the colloidal loess water producing tank, . The colloidal ocher water dilution tank (14) mixes colloidal ocher water one more time to produce more colloidal ocher. It has a tank structure that makes the loess particles into a colloid state with the particle structure of the biorhythmic organism by the rising current, and filters out the granular form which is not yet caught in the stirring tank. And because the secondary loess water is concentrated, dilute it to make the colloidal loess soil suitable for red tide relief in this tank. The tanks may be made as one, but they may be divided into two tanks for mixing the materials such as electrolytic water (acidic electrolytic water and alkaline electrolytic water) which improve the efficiency of the loess, respectively.

The number of colloidal yellow stones is done twice, first and second, the difference being as follows. As shown in Table 1, the particle constitution of the loess water at the suspension level prepared in the trough-loading and crushing suspension manufacturing tanks can be found to be 20% or more of particles having a particle size of 1,000 μm or more, It can be seen that the ratio of the fine particles having a very large bloom relief effect of 0 ~ 50 ㎛ increased by 83%. Particle analysis was carried out by preparing the sheaves for each mesh, and analyzing the particle sizes by applying a strong flow of seawater to the loess without applying any force.

7 shows a circle in the colloidal loess water producing tank and the colloid in the colloidal loess water dilution tank in which the loess water is stirred and diluted in the tank to rotate the loess water.

In FIGS. 1 and 2, among the pumps 3, 4 and 5, which pump seawater into the tank to stir and dilute the loess water, the pump 3 produces a strong water current in the loess colloid loam tank 13, Since the tank height is higher than the dilution tank (14) due to the primary colloidization, and the loess water can protrude out due to the strong rotating water flow, the loess water leakage prevention plate as shown in FIG. 2 is attached to the inner side at an angle of about 10 ° I left it. In contrast, pumps 4 and 5 have a smaller capacity than pump 3 by about 2/3, reducing the rotational flow rate and precipitating some remaining small particle sand.

(6) A method of spraying the final colloidal yellow soil water and its apparatus will be described. The high-speed spraying pump 6 is a multi-stage pump capable of spraying a large amount of colloidal yellow soil water at a high pressure and a high speed. The high-speed, high-pressure multi-stage spray pump is two units, and allows two different kinds of colloidal yellow loam mixed with the same colloidal yellow soil water or electrolytic water to be sprayed in different directions. The spray nozzles of the loess high-speed spray nozzle can be alternately replaced with nozzles capable of adjusting the spray amount and distance of the spraying colloidal loess water. As shown in Fig. 8, the present nozzle may be a general fire nozzle (Fig. 8) or a dedicated nozzle.

The underwater spraying nozzle or the underwater spraying nozzle by the high-speed spraying pump 6 can be applied to the underwater spraying nozzle or the underwater spraying pump 7 at the back of the loess spraying vessel and sprayed strongly in water. This is because when the red tide creatures are distributed in the deep water layer in the middle layer or more, if the spraying nozzle is shortened and the loess water is sprayed by the natural falling method, only the red tide creature of the surface layer is effective for red tide, This is because the red tide creatures in the deep water layer over the middle layer are also well remedied.

(7) Other facilities. Various pipes should be installed with a grade of about 5 ° so that the loess water and the suspension are transferred to the loess particles without clogging in the middle. The wires drive each pump, and the wires that supply electricity to the other devices are protected by the arc tube so that wires and sheaths of a certain size are not peeled off. Stainless steel bolts and nuts are used because of various types of handles such as bolts and nuts exposed to seawater. Various valves such as water flow control and check valves are also used in accordance with the regulations, and other strainer, Do not use stainless steel products. Balanced over drain piping line installation is considered to prevent reverse flow and keep water flow by overdrain installation.

The seawater supply pipe 24 is a pipe for supplying seawater to the pump, and the suspension transfer pipe 25 is a pipe for transferring the suspension. The loess water leakage prevention plate 26 is a plate for preventing the loess water from flowing out, and the colloidal loess water high speed injection pipe 31 is a pipe for spraying the colloidal loess water at high speed. The colloidal yellow soil high velocity injection nozzle 33 is a nozzle for spraying the colloidal yellow soil water at a high speed and the colloidal yellow soil water pipe 34 is a nozzle for spraying the colloidal yellow soil water, Is a piping for spraying colloidal yellow soil water into water.
