JPH08150304A - Device for removing floating particulate - Google Patents

Abstract

PURPOSE: To provide a device for removing floating particulate in which the whole equipment is directly immersed in water such as lakes and marshes, rivers and an inland sea and which is of low cost. CONSTITUTION: When dirty water is caused to flow in a removal box 2 by using a natural flow of lakes and marshes, rivers or the like and is passed between parallel plates 7 of an inclined plate group 3, particulate is precipitated by gravity and removed from the dirty water. The dirty water is caused to flow and is circulated from a fine flow hole 12, and the removed particulate is collected in a collecting space 9 below the parallel plates 7 and is properly discharged. In this way, since the natural flow is used, power for flowing in the removal box is not required. Since the influence of the water flow is restrained by the removal box, particulate precipitated on the parallel plates is prevented from stirring up.

Floating particles are generated in water and become polluted. Further, in lakes, rivers, inland seas, etc., fine particles such as phytoplankton are generated and suspended due to the supplied nutrient salts, and due to a large amount generated under a certain environmental condition, pollution problems such as red tide have been developed. Further, in an elevated water tank such as a building or a condominium, floating particles such as iron rust are brought into the water tank through a pipe, and there is a problem of water pollution due to sedimentation and accumulation. In order to solve the problems caused by these suspended particles, it is desired to develop a technique for capturing and removing particles suspended in water.

伴うコストが発生していた。Conventionally, as a technique for purifying water by capturing and removing fine particles floating in water, a technique of removing fine particles by using a filter or installing several parallel plates with an interval of several mm is used. There are techniques for rapidly setting floating particles. In the case of using a filter, the trapped fine particles clog the filter, which necessitates cleaning and replacement, which is troublesome, and the cost associated with the exhaustion of the filter occurs.

粒子は浮遊し続けることになる。By the way, in the case of a device for capturing and removing suspended particulates using a parallel plate, it is effective only in a use environment where there is no flow of water. It is not practical because it rises again due to water flow caused by various causes. That is,
When used in an ornamental fish tank, convection due to aeration occurs, and when used in lakes, rivers, or the sea,
Water is constantly moving due to convection due to temperature difference, wind pressure, etc., and flow due to drop. When the fine particles are suspended in water, the specific gravity of the fine particles is slightly heavier than that of water, so that the fine particles tend to settle by gravity, but it is difficult to fly up and settle due to the flow of water. In particular, the finer the suspended particles are, the smaller the particles flow up, and the fine particles continue to float.

It must be able to utilize the flow and have the ability to capture and remove even if the entire device is submerged in water.

水中の透明度を向上させ得ることを発見した。The present inventor has a structure in which the trapping and removing means using the inclined plate group is provided inside the box so that the box itself can be installed in a fluid such as water, and a fine hole is provided in the side wall of the box. As a result, polluted water flows into the inside of the box by a natural flow, and when water is circulated inside and outside the box while capturing and removing particles when passing between parallel plates, the particles settled inside the box will flow. Prevents you from soaring again,
It has been discovered that it can improve transparency in water.

いくような構成を採用した。That is, as the device for trapping and removing fine particles in the present invention, a trap box having a water inlet at the top and which can be installed in water is provided, and a large number of parallel plates are obliquely arranged at predetermined intervals inside the trap box. A fine water outflow hole is provided on the side wall of the trap box at the lower end of this parallel plate to form a circulation path connecting the water inflow port and the water outflow hole of the trap box to the outside, and flow into the circulation path inside this trap box. The fine particles floating while the water passing through the gaps between the parallel plates were settled on the parallel plates, and were further settled by the gravity along the upper surface of the parallel plates to the bottom of the trap box.

成を採用した。Further, a space for accumulating the trapped particles in the trap box is required, and it is necessary to prevent the accumulated particles from flowing out of the trap box again. Further, since the water that has flowed into the trap box is reused, it is necessary to flow it out of the trap box again and circulate it. Therefore, in order to satisfy these conditions, a fine particle accumulation space for accumulating fine particles that have fallen by gravity on the parallel plate is provided between the bottom of the trap box and the lower end of the inclined plate group, and On the side wall, a fine outflow hole is formed at the uppermost position of the fine particle accumulation space in accordance with the distance between the parallel plates of the inclined plate group, so that the accumulated fine particles can be prevented from flowing out and the inflowing water can be reused. Adopted the configuration.

流入口に容易に取り込むことができる。Since this apparatus is so constructed as to be submerged in a fluid such as water, natural energy can be used as a means for causing polluted water to flow into the trap box. For example, when installing this device in an aquarium for ornamental fish, there is convection due to aeration, and when installing this device inside an elevated aquarium such as in a building or condominium, there is a vortex that occurs when water is used due to head pressure. In the case of rivers, there is a natural flow due to the head, in the case of lakes and convections that occur due to temperature differences due to the heat of wind and sunlight, and in the case of the inland sea there are tidal currents, etc. Can be easily taken into the upper inlet.

That is, the fine particle capture and removal apparatus according to the present invention is an air cleaning apparatus in a clean room, by appropriately selecting the material, size, outflow hole diameter, and the like.
It can be applied to various devices such as soot removing device of diesel engine, thermal power plant, soot removing device of boiler chimney of factory, soot removing device of crushed stone plant, cement plant, etc., sawdust recovery device of sawmill.

る構成を採用することが望ましい。Since the water flow flowing into the trap box differs depending on the magnitude of the disturbance energy, a vortex flow etc. is generated at the inlet, and when the water flows between the parallel plates, the disturbance energy accumulates on the parallel plates. There is a possibility that the fine particles that have sprung up. Therefore, in the trapping box, a rectifying plate is provided between the fluid inlet on the upper side and the inclined plate group in order to buffer a strong flow accompanied by an oblique vortex and guide it smoothly to the inclined plate group. It is desirable to adopt.

の構成も採用可能である。Further, referring to the parallel plate spacing of the inclined plate group, a suspended matter having a large sedimentation velocity, that is, one having a large specific gravity or one having a large particle diameter is captured even if the water flow passing through the parallel plates is somewhat fast. So in this case,
Larger outflow holes allow for treatment of larger amounts of water. On the other hand, when particles having a large particle diameter try to pass between closely-spaced parallel plates, they may be caught between the parallel plates and obstruct the flow, and the desired trapping and removing function may not be exhibited. Therefore, in order to capture and purify various fine particles in water from large to small particles with specific gravity or particle size, parallel plates are laminated in a composite state from coarse to dense ones. The configuration of the inclined plate group can also be adopted.

を防止することができる。Further, among the fine particles passing through the inclined plate group, the capture rate of the fine particles which are not captured in the fine particle accumulating space and flow out to the outside through the outflow hole is as described above when the sedimentation velocity of the fine particles is high, that is, outside the fine particles. When the diameter is large, when the length of the parallel plate is increased, when the width of the parallel plate is increased, when the inclination angle of the parallel plate from the vertical line is increased, and when the flow velocity near the entrance of the parallel plate is decreased. , It can be raised when the diameter of the outflow hole on the side wall of the trap box is reduced. That is, the capture rate mainly depends on the area of the parallel plates and the water passage speed. Therefore, in order to improve the capture rate,
If the area of the parallel plate cannot be changed, it can be dealt with by reducing the outflow hole to reduce the flow velocity. Therefore, a mechanism that can adjust the hole diameter of the outflow hole according to the amount of treated water, that is,
The capture rate can be appropriately selected by adopting a configuration in which a shutter that can adjust the hole diameter of the outflow hole is provided. Further, by completely closing this shutter, it is possible to prevent fine particles from spilling out from the outflow hole when pulling up and cleaning the trap box.

に設定されることが望ましい。Next, referring to the inclination angle of the parallel plates of the inclined plate group, the reason why these parallel plates are inclined is as follows. That is, when the parallel plates are made horizontal, the floating fine particles sink and accumulate due to gravity, but they cannot be accumulated in one place. On the contrary, when the parallel plate is set up in the vertical direction, the fine particles can be dropped into the accumulation space, but the fine particles cannot be precipitated on the parallel plate. Therefore, by inclining the parallel plate, the fine particles are precipitated, and the precipitated fine particles are dropped along the parallel plate,
It can be accumulated in the accumulation space. This tilt angle is
The capture rate improves as the angle of the parallel plates from the vertical line increases, but the particles trapped by the parallel plates are less likely to slide down and may be deposited on the parallel plates. The angle is 30 ° to 45 ° from the vertical line
It is desirable to be set to.

ばよい。The fine particles accumulated in the fine particle accumulation space increase in level as they are accumulated, and if the level exceeds the level of the outflow hole on the side surface of the trap box, the fine particles flow out to the outside through this outflow hole and lose their function. become. Therefore, it is necessary to remove the accumulated fine particles by cleaning. For a shallow water such as a fishbowl, the device itself submerged in the fishbowl may be pulled up to the surface of the water, the fine particles accumulated in the fine particle accumulation space may be removed from the inclined plate group, and the fine particles at the bottom may be discarded together with water. In addition, for an apparatus installed in a place where the depth of water is out of reach of the hands, a string or the like may be slowly pulled up to pull up the apparatus from the water surface, and the accumulated fine particles may be removed in the same manner as above.

If the accumulated particles can be easily taken out from the outside of the elevated water tank, the time required for cleaning can be shortened. The present inventor, in consideration of the above points,
The time required for cleaning was shortened by adopting a structure in which a discharge port for discharging fine particles accumulated in the fine particle accumulation space is provided at the bottom or lower part of the trap box. In the case of an elevated water tank, the pipe end of the thin tube connected to the discharge port is usually closed by a valve.When the particles are full, the valve is opened to flow from the thin tube by the head pressure of the elevated water tank, and the particles are discharged. Can be discharged outside.

It is also possible to employ a configuration in which a pipe is connected to the discharge port and fine particles are sucked and collected together with water by a separately installed pump. A submersible pump may be installed if there is no problem of metal corrosion in fresh water. Since the recovered fine particles are considered to have the same components as the sewage sludge, it is possible to spray them directly into the waste incinerator and incinerate them, or to remove the water with a filter and incinerate them in the form of sludge cake. In addition, instead of the outlet,
It is also possible to adopt a configuration in which a drawer is provided at the bottom of the trap box and a fine particle accumulation space is provided in the drawer.

The water introduced into the trap box flows between the parallel plates and flows out to the outside from the fine outflow holes provided in the side wall of the box. The flow velocity of the water flow passing through the parallel plates is reduced according to the ratio of the opening area of the parallel plates and the area of the outflow holes of the side walls. The water flow passing between the parallel plates forms a laminar flow, and the flow velocity is low in the part close to the parallel plates and fast in the middle part of the parallel plates. Since the flow velocity is slow in the part close to the parallel plate, the fine particles start to settle, and the settled fine particles further approach the parallel plate and enter the part with the slower flow velocity, and finally settle on the parallel plate surface. . Since the flow velocity near the parallel plate is almost zero, the fine particles that have reached the parallel plate settle along the parallel plate and are accumulated at the bottom of the trap box. The water flow passing through the parallel plates circulates while losing fine particles at a constant rate every time the water flows between the parallel plates, thereby improving the transparency in water.

Since the water is shallow in ornamental fish tanks, etc., if you take out the device as it is, or if you want to install it in a deep water place, connect the string to the device beforehand, take it out to the water surface appropriately, and take out the inclined plate group. After that, the accumulated fine particles are discarded together with water. Fine particles remaining on the bottom of the trap box should be washed off with tap water. Further, it is also possible to discharge the fine particles from the discharge port through a thin tube, and in this case, it is possible to simply dispose of the trapping box without taking it out of the water.

FIG. 7 shows a state in which the fine particle capturing / removing device 1 is used for the purpose of purifying the water in the ornamental fish tank 20. In this case, the aquarium 20 is aerated.
Convection of water occurs inside, and the water in the water tank flows in through the opening 4 of the trap box 2 by utilizing this convection. While the inflowing water passes between the parallel plates 7 of the inclined plate group 3, the fine particles having a larger specific gravity than the water settle due to gravity, and are trapped by the parallel plates 7. The fine particles captured by the parallel plate 7 fall along the inclination of the parallel plate 7 and fall and accumulate in the fine particle accumulation space 9 secured below the inclined plate group 3.

められる。The water containing the untrapped fine particles flows out through the outflow hole 12 formed at the lower end portion of the parallel plate 7, and these actions are continuously repeated to circulate the water. The water in the water tank 20 will increase its transparency. The final reaching point of the transparency is determined by the ratio of the generation rate and the trapping rate of fine particles newly generated in the water tank 20.

定期的に除去すれば腐敗も起こらない。Generally, the water quality is deteriorated because the suspended fine particles are decomposed to generate a gas such as hydrogen sulfide or methane gas. When the present apparatus 1 is used, it takes a long time after the fine particles are generated. Since the particles are captured and removed before they are removed, if the particles accumulated in the particle accumulation space 9 of the present apparatus 1 are removed regularly, spoilage does not occur.

温期で２週間程度で清掃し好成績を保っている。The removal of the accumulated fine particles is performed until the level of the outflow hole 12 is reached. Since the water is shallow in an aquarium for aquarium fish, the trapping box 2 is taken out as it is, and the inclined plate group 3 is taken out from the trapping box 2, and then the accumulated fine particles are discarded together with the water. Fine particles remaining on the bottom surface of the trap box 2 are washed off with tap water or the like. In the experiment, cleaning was carried out in low temperature in winter for 4 weeks and in high temperature in summer in about 2 weeks, and good results are maintained.

Therefore, the fine particles settled on the parallel plate 7 are subjected to the decomposition action of aerobic bacteria before settling in the accumulation space 9. According to the experimental results, width 350mm, depth 180mm, depth 200
A large goldfish 3 is bred in a water tank 20 of about mm, and a value of 7.5 is obtained without changing water for 10 months.

化作用が行われ、その効果も大きい。FIG. 8 shows an example in which two apparatus 1 are mounted on a mounting table 22 installed on the bottom of a water such as a lake, a river or an inland sea. In the case of lakes and marshes, convection occurs due to the temperature difference between the water surface and the bottom of the water due to sunlight, and in the case of rivers the flow occurs due to the head difference due to the inclined surface. Water is generated, and water flows into the trap box 2 due to these natural flows, and the purifying action is performed.
In particular, in the case of a river or the like in which a large amount of fine particles are suspended and is spoiled, the spoiled fine particles continue to float because the particle diameter becomes smaller, but when they flow into the device 1, the specific gravity of the spoiled fine particles is larger than that of water. Since it is also heavy, the same purifying action as that for the above ornamental fish is performed and its effect is great.

9 are connected, and the fine particles are sucked and collected together with water by the pump 25 separately placed on the shore or the like through the thin tube 19. Submersible pumps may be installed if there is no problem of metal corrosion in fresh water such as lakes and rivers. Since the collected fine particles are considered to have the same components as the sludge of the sewage, it is possible to spray them as they are inside the refuse incinerator and incinerate them, or to remove them with a filter to incinerate them in the form of sludge cake.

When the apparatus 1 is installed in the elevated water tank 26, a head pressure in the water tank causes a swirl or the like, which causes water to be taken into the trap box 2 and the fine particles such as iron rust are trapped and trapped. Further, the fine particles accumulated in the fine particle accumulation space 9 can be discharged to the outside by opening the valve 27 at the tip of the thin tube 19.
