Description

Mobile float removal device

The present invention relates to a mobile float removal device for removing eutrophication or oil strips while moving along the surface of a lake or reservoir or sea.

In lakes, reservoirs, or seas, red tide or green algae are caused by eutrophication due to overproliferation of phytoplankton, and if these red tide or green algae cannot be removed, they can damage aquatic plants and fishes while being used as water resources. There is a problem that it is difficult to stop the intake.

As a method of eliminating green algae and red tide, a method of killing phytoplankton by spraying algae on the lake, dredging the scoop to prevent the re-dissolution of organic matter or phosphorus in the lake spool, circulating the water in the lake, fine An air flotation method using air has been proposed, but the method has a problem of causing secondary pollution or costly for construction and maintenance operation.

In addition, since the eutrophication material is not generated in a fixed place and is fluid, it is difficult to utilize the equipment to remove it in a fixed manner, and the method of using the chemical is not recommended because of the problem of secondary pollution.

In addition, when oil spills occur, the oil band spreads widely, but uses an absorbent cloth or a drug, but there is a problem that can not extend the adsorption range when using the absorbent cloth, there is a problem of secondary pollution when using the drug.

In the present invention, when removing the eutrophication substances or oil strips causing red tide or green algae, the fixed removal facility has a limitation in position movement, and the precipitation method cannot cover a large area, and the problem of secondary pollution when using chemicals is eliminated. In order to solve the problem, it is possible to remove eutrophication materials or oils and then remove them, but to use them while moving in an appeal or river or sea.

The present invention is provided with a vessel for movement in water, is provided with a collection tank towed to the vessel and submerged in a substantial portion of the water, and installed in the collection tank to spray the flocculant while aerated air to the upper side, And a discharge plate coupled to the collection tank and installed obliquely to discharge only the co-nutrients aggregated from the collection tank to the rear, and having a loading box for loading the co-nutrients coagulated to the discharge plate. By moving the air supply and flocculant to the collection tank to the flocculation of the eutrophic material is made, but the flocculated eutrophic material is filtered by the discharge plate to be filled in the loading box.

The present invention is used to effectively remove the oil strip when the oil leakage accident occurs and the oil strip is formed on the water surface.

In the present invention, there is no restriction on the place because the work is performed by moving to the point where eutrophication occurs or the oil strip is generated, and the flocculation agent or oil is agglomerated effectively using flocculant, but the flocculated eutrophication material or oil is loaded separately. Because the treatment is not mixed with water by using it can be expected a complete treatment without secondary pollution, there is an advantage that the removal of eutrophic substances or oil strips based on a relatively simple structure.

In addition, the present invention can be moved and used to actively remove contaminants.

The present invention includes a vessel 10 that provides movement and traction power in water and eutrophicates a collection tank 20, a discharge plate 30, and a loading box 40 provided with a pipe 21 for ejecting air and flocculant. Allow them to be dragged to the place where the substance or oil strip occurred.

The collection tank 20 of the present invention has a U-shaped cross section and has an open shape before and after, having a space on a wall so as to sink to a certain depth on the surface of water and to expose a certain height on the surface of the water, as necessary. The front of the collection tank 20 to install the collecting wings 22 to be wide open so that a large amount of collection can be made.

The collection tank 20 is connected to the rear of the vessel 10 to be towed, so that the eutrophication material can be collected in the collection tank 20 in the same form as Samtaegi so that water can be discharged to the rear. And, usually the eutrophication material is inhabited about 30cm from the water surface, the collection tank 20 to sink to a depth of 30cm or more to be moved to a state that does not completely sink.

The collection tank 20 is installed by double the outer wall to contain air so that at least 30cm or more can be moved while locked, so that part of the surface floating in the exposed state.

The collection tank 20 may be provided with several pipes 21 toward the bottom, but the air or flocculant may be ejected to the pipe 21 by forming several holes or installing nozzles upward. Air or flocculant is blown upwards.

Here, the pipe 21 is installed a plurality of pipes from the front to the rear toward the surface closer to the installation, the pipe 21 for supplying the coagulant is supplied between the pipe 21 is supplied with air, the collection tank 20 In front of the discharge plate 30 installed in the rear to allow the air to be ejected toward the rear side to facilitate the movement of the eutrophic material aggregated to the discharge plate (30).

That is, when the collection tank 20 moves, the eutrophic material moves to the collection tank 20, and at this time, the air and flocculant are ejected to the pipe 21 so that the eutrophic material is agglomerated by the air and then coagulated by the air. The material moves to the water surface. Air or flocculant supplied to the pipe 21 is to be supplied through the hose in the vessel (10).

Install the discharge plate 30 inclined rearward in the collection tank 20, but the discharge plate 30 is to be locked in the front part about 5cm, the rear is placed on the water, the discharge plate 30 is Only agglomerated eutrophic material is discharged to the rear, and water is discharged through the lower portion of the discharge plate 30 and the collection tank 20.

That is, when the flocculant is added, the eutrophic material is agglomerated, the agglomerated eutrophic material is moved to the water surface by air blowing, and the collection tank 20 is driven by the vessel 10 The agglomerated eutrophic material is moved to the upper portion of the discharge plate 30, the water not containing the eutrophic material is discharged through the lower portion of the discharge plate (30).

In order to collect the coagulated eutrophic material present on the water surface, the discharge plate 30 is locked about 5 cm, and the discharge plate 30 is installed at a low front and high rear, so that only the coagulated eutrophic material is discharged. Ride up, so that the water does not go over the discharge plate (30).

Here, the condensed eutrophic material ejects air toward the rear from the pipe 21 in order to pass over the discharge plate 30 so that the aggregated eutrophic material passes over the discharge plate 30.

The discharge plate 30 is locked to the front surface so that the condensed eutrophic material can be easily moved to the discharge plate 30 and then moved by air pressure outside the water surface so that the aggregated eutrophic material is discharge plate 30. Ride over, the water does not ride over the discharge plate (30).

After the discharge plate 30 is connected to the loading box 40, all of the aggregated eutrophic material is filled in the loading box 40, emptying the loading box 40 when the agglomerated eutrophic material is filled in the loading box 40 To work again, the aggregated eutrophication material filled in the loading box 40 is to be treated environmentally friendly through a separate treatment process.

On the other hand, the present invention is not only used for the treatment of eutrophic material, but can be used to effectively remove the oil strip when the oil strip occurs, when the flocculating agent that coagulates oil, the oil is coagulated and loaded into the loading box (40) You lose.

And the present invention can be used in a state in which the collection tank 20 and the discharge plate 30 and the loading box 40 is fixed without moving while using the ship 10, in this case using a hose from the outside Air and flocculant must be added.

The present invention connects the collection tank 20 to the rear end of the vessel 10, so that the air and flocculant can be supplied using the pipe 21 and the hose, the vessel is installed inclined to the rear upper side of the collection tank 20 Publication 30 is connected to the loading box 40 by using the vessel (10) when the eutrophication proceeds or to operate the place where the oil band is formed, the eutrophication material or oil meets the flocculant, the coagulation is made by the air It is moved to the surface, and the agglomerated eutrophic material or oil is gathered in the loading box 40 by using the air discharge plate 30 again. Strips can be removed.

Since the present invention uses the vessel 10, it is possible to cope with the generation of eutrophication substances or oil bands actively by using a mobile type, not a fixed method, and to remove the aggregated eutrophication substances or oil from the water completely. Likewise, secondary pollution due to the use of flocculant can be eliminated, and in particular, since the eutrophication is completely removed, further eutrophication can be prevented.
