Description

  The present invention relates to a method and apparatus for producing refined product-containing water, and more particularly to an apparatus for easily and reliably producing refined product-containing water by a method of colliding water streams, and a method for using the produced refined product-containing water. .

At present, various granular materials (lumps) are used in various industries. These powders exist in a wide range of particle sizes, from those having a particle size of several millimeters to those in which several molecules are associated at a microscopic level.
In many cases, it is desirable to refine these granular materials to the micron level in the case of several millimeters and to the nano level in the case of the micron level.
For example, in the case of sewage treatment by the activated sludge method, a lump of activated sludge (microorganisms) is brought into contact with sewage in an aeration tank, and the pollutant in the sewage is digested to purify the sewage. In this case, as the activated sludge (microorganisms) in the form of a mass is refined without associating and the diameter thereof is smaller, the contact efficiency between the microorganisms and the pollutant is improved and sewage purification is promoted.

The conventional activated sludge method is intended to improve the contact efficiency between microorganisms and pollutants by agitating the inside of the aeration tank. However, the agitation alone hardly changes the activated sludge itself, and the processing efficiency is improved. There is only a slight improvement.
Even in various wastewater treatment methods other than the activated sludge method, the pollutants in the wastewater are often present as lumps or granules, and if the lumps or granules can be further refined, drainage purification is easier. Can be done.

Furthermore, in a plant that uses a bulk material to produce various chemical substances, the bulk material is pulverized into powder, dissolved or suspended in a solvent, and other reactants are added to the solvent. A predetermined chemical reaction is allowed to proceed by stirring.
However, there is a limit to miniaturization in normal pulverization, and in the chemical plant, it is necessary to heat and stir for a long time to dissolve the raw material and advance the reaction, which is a loss of time and cost. If the raw material can be pulverized to a finer level, the reaction can proceed with low heating and in a short time. However, at present, there is no appropriate pulverizing means, and heating for a long time is essential.

In buildings such as condominiums and office buildings, piping for circulating water and cooling / heating air is arranged on the inner wall, floor, ceiling, and the like. If these pipes are used for a long period of time, the inner surface of the pipes may corrode and contaminate water and gas in the pipes. In order to prevent these, a rust-preventing coating may be formed on the inner surface of the pipe, but it is difficult to form a coating on the inner surface of a long pipe, and the coating is not actually formed.
Furthermore, oil tankers that have been emptied are filled with ballast water to adjust the balance of the tankers, thereby ensuring safe operation of the tankers. The inner surface of this oil tank is easily contaminated with crude oil containing a large amount of pollutants, and seawater is used as ballast water to replace crude oil. Corrosion and contamination of the oil tank inner surface due to salt and algae occur, and countermeasures are required. Has been.

For example, Patent Document 1 discloses that microbes and bacteria are refined by applying an impact with ballast water, but there is no disclosure about contamination of an oil tank or prevention of contamination by ballast water or crude oil.
Furthermore, the edible sauce contains a large amount of spices and other powders, but if these components can be further refined, a sauce with excellent taste in which the components are dispersed can be provided. Although it is relatively easy to further refine the conventional source powder and granule itself, the sauce is a relatively inexpensive product, and much effort and high cost cannot be taken for the refinement.

JP 2005-271648 A

As for the refinement of the lump or powder, the pulverization by various mills is almost all, and the pulverization by the mill has a limit in the miniaturization, and the miniaturization beyond a certain level is impossible. In particular, crushing at the micron or nano level cannot be performed.
In spite of the demand for highly miniaturized lump bodies and powder particles, the conventional miniaturization method does not meet the demand.
Accordingly, an object of the present invention is to provide a method and an apparatus capable of highly refining a lump or powder and a method for treating the water containing the refined product obtained thereby.

The method of the present invention is a method for producing refined product-containing water, characterized in that the particulate material is refined by colliding two or more water streams having at least one refined particulate material. The inventing device has two supply pipes which are formed in a hemispherical shape on the tip side of a cylindrical body, a small hole is formed in the center thereof, and the two small holes are opposed to each other and arranged linearly, and the two A water supply port for supplying a water flow having a granular material that refines from the tangential direction, formed on the base end side of each of the supply pipes, and a water containing a refined matter, It is a manufacturing apparatus.
The refined product-containing water thus obtained can be used, for example, as a reducing agent-containing water having a refined reducing agent in order to form a reducing agent coating film on the inner surface of the pipe or the oil tank inner surface of the tanker. Furthermore, the apparatus and method of the present invention can be used to refine the activated sludge and the sterilization target in the activated sludge method, further refine the contaminants in the waste water, and improve the treatment efficiency. It can also be used to promote dissolution of chemical substances in chemical plants.

The present invention will be described in detail below.
In the present invention, two or more water streams each having at least one granular material to be refined are collided. Thereby, the said granular material collides with each other, or the said granular material collides with a high-speed water flow, and is refined | miniaturized. In the present invention, the conventional lump and powder are collectively referred to as “powder”, and the particle size of the powder before refining is usually several tens of nanometers to several centimeters. In particular, the present invention intends to further refine a granular material that has already been refined.

  In the present invention, a plurality of water streams each having at least one granular material are caused to collide with each other. It is desirable that the number of water streams be two and that they collide with each other at 180 °, that is, frontal collision. As a result, both water streams collide at a speed equal to the sum of the flow velocities of both water streams, and the impact reaches several to ten times that when a single water stream collides with a stationary surface, giving each water stream the maximum impact. In the case where the granular material in the water stream is refined and the refined substance is water-soluble, dissolution in the water stream is promoted.

  The number of water streams and the collision angle are not limited to this, and three water streams can collide with each other at 120 °, or four water streams can collide with each other at 90 °. It is also possible to collide at an angle other than 180 °. In any case, a significantly larger impact is applied to each water flow than when a water flow having powder particles collides with a stationary surface, and the refinement of the powder particles is promoted.

It is desirable that two or more water streams in the present invention collide at the fastest possible speed. For this purpose, it is desirable to pass a small-diameter hole or slit immediately before the collision.
However, rather than simply increasing the speed to the maximum, in the case of two water streams, the characteristics of both water streams may be slightly different, for example, one flow rate may be slower than the other, The particle size of the powder particles can be varied. When a large-diameter granular material and a small-diameter granular material collide, it can be estimated that the balance between the two is lost and miniaturization easily proceeds.

The water flow is arranged in a straight line with one end of two linear cylinders facing each other, the water flow is sent from the other end side of the two pipes by a pump, and collided on the opposite end side. However, it is difficult to obtain a high-speed water flow with this method. Accordingly, it is desirable that the refined product-containing water production apparatus of the present invention has the following configuration.
That is, two supply pipes in which the distal end side of a relatively large diameter cylindrical body is formed in a hemispherical shape and a small hole is formed in the center thereof are arranged in a straight line with the two small holes facing each other, and the two It is desirable to supply a water stream having powder particles from the tangential direction to each base end side of the supply pipe. These water flows swirl while contacting the inner wall of the supply pipe, move while accelerating toward the tip side, and are ejected from the small holes at high speed, and the two water streams ejected from the opposing small holes are between the small holes. Colliding in each other's space and giving each other a violent impact.

The cylindrical body may be formed so that the inner wall of the cylindrical body has the same diameter except for the tip, but if it is inclined inward from the base end side toward the tip end, acceleration is promoted, and the water flows at a higher speed. A collision is realized.
As described above, this impact refines the granular material in the water flow.

The refined product-containing water obtained in this way is taken out of the apparatus from the water outlet, but a baffle plate having one or more through holes may be installed at the water outlet. This baffle plate provides resistance to water flow extraction, and the water flow can be retained in the space between the small holes for a long time.
On the contrary, the water containing fines may be taken out by sucking with a pump or the like from the water flow outlet provided with the baffle plate.
If the apparatus of such a structure is used, as above-mentioned, the refined material containing water which has the granular material refined | miniaturized from the raw material granular material is obtained.

The energy required for the operation of the apparatus of the present invention is basically only energy that generates a water flow and supplies it to the apparatus body, which is very economical.
The granular material of the present invention includes (1) activated sludge for wastewater treatment or pollutants contained therein, (2) pollutants contained in wastewater, (3) pollutants contained in sewage and urine, (4) Chemical substances used in chemical plants, etc. (5) Reducing agents for forming reduced coatings in piping or tanker oil tanks, (6) Pollutants in lake water, river water or seawater, (7) Bathhouses There are pollutants in water, (8) pollutants in heat exchanger cooling water and boiler water, and (9) pollutants in papermaking washing water. However, the granular material of the present invention is not limited to these.

When the activated sludge of (1) or the pollutant contained therein is a powder, for example, the refined product-containing water production apparatus main body is submerged in an aeration tank in a treatment line. The waste water (waste water) supplied to the aeration tank contains pollutants such as bacteria, molds, and waste chemicals, but in the apparatus main body, the activated sludge and the water containing the refined matter in which the pollutants are refined are contained. Is supplied into the aeration tank from the water outlet of the apparatus. The activated sludge and the pollutant have a large surface area to each other, which increases the contact area and leads to an improvement in processing efficiency.However, in this aspect, since both are refined, the activated sludge is sufficiently in contact with the pollutant. Promotes its decomposition. Further, since the water flow containing the pollutant in the apparatus collides with a large impact, the germs and the like may be killed by the impact and the processing efficiency may be increased. In addition, when the impact is strong enough to kill microorganisms of activated sludge in addition to various germs, it is necessary to adjust so as to reduce the speed of the supplied water flow. In the activated sludge method, the apparatus may be connected to the piping before the aeration tank without being submerged in the aeration tank.
The adjustment of the speed of the water flow is unnecessary when the granular material is the above-mentioned (2) to (9).

A sufficiently dissolved or suspended solution or suspension can be obtained by refining the chemical substances (reducing agents) described in (4) and (5) above. In the case where the chemical substance is hardly soluble, the chemical substance is refined by collision with water flow, and a desired liquid can be obtained in a much shorter time and at a lower cost than before.
Dissolved or suspended liquids with poorly soluble reducing agents flow through pipes for water supply and cooling / heating circulation in buildings such as condominiums and office buildings, or supply them as ballast water to tanker oil tanks from which crude oil has been extracted. In particular, it can be used to protect the piping and the oil tank by forming a reduction film on the inner surface of the piping and the oil tank.
A granular material classified as a pollutant can easily separate and decompose a fine pollutant, and can smoothly purify water.

In the present invention, in addition to the refinement of the granular material, a tankless line may be installed either before or after the refinement device to promote treatment or reaction of the refined granular material, It is desirable to maintain high temperature and high pressure in the tankless line. In the present invention, high temperature generally means 50 ° C. or higher, and high pressure means 1 MPa or higher.
Especially in the critical state (in the case of water, 375 ° C. or higher, 22 MPa or higher), it becomes a supercritical fluid that is neither a liquid nor a gas, and its superior properties are used for extraction, purification, washing, preparation, processing, functionalization, and reaction. Promotion etc. can be executed. For example, in the case of wastewater, even if the target wastewater is simply brought into contact with the nanobubbles through the first invention apparatus, the wastewater is purified by the sterilizing power of the nanobubbles. When it is introduced into the wrestline, the contact between the waste water and the nanobubbles further proceeds and the treatment efficiency increases.
The length of the tankless line is preferably in the range of 1 m to 300 m, and the inner diameter is preferably 5 mm to 100 mm, but is not limited thereto. If the length exceeds, for example, 10 m, it is desirable to reduce the installation space by folding the tankless line.

  The present invention makes it possible to produce refined material-containing water by a simple operation of refining the granular material by colliding two or more water streams each having at least one granular material. When a plurality of water streams having such granular materials collide, depending on the collision angle, each water stream collides at a maximum speed equal to the sum of the flow speeds of each water stream. The impact at that time is not simply twice that of a single water stream colliding with the impact surface, but increases exponentially as the impact speed increases, giving each water stream the maximum impact. It is done. Thereby, refinement | miniaturization of a granular material is accelerated | stimulated.

And a side view of the three spacers (bolt holes are omitted).

A laterally cylindrical outer cylinder 1 has a refined-containing water guide tube 2 bent upward at the center of the upper surface, and a horizontal flange 3 is joined outwardly to the upper end edge of the guide tube 2. .
On the upper surface of the horizontal flange 3, a baffle plate 5 having a slightly small diameter and having four through holes 4 (only one is shown) is located. A take-out (spout) port 7 is installed, and the refined product-containing water take-out port 7 is fixed to the outer cylinder 1 by tightening the horizontal flanges 3 and 6 with bolts 8.

  A support plate 9 whose upper part is curved in a semicircular shape is joined to the outer peripheral sides of both ends of the outer cylinder 1, and an inner cylinder mounting plate is inserted into the circular hole 10 at the joint between the support plate 9 and the outer cylinder 1. (Flange) 11 is fitted. The outer edge of the base end portion of the cylindrical turning inner cylinder 14 whose tip side is formed as a hemispherical ejection portion 13 is joined to the circular hole 12 at the center of the inner cylinder mounting plate 11. Is formed with a small-diameter ejection hole 15. 1 is formed such that the diameter of the left-hand ejection hole 15 in FIG. 1 is smaller than the diameter of the right-hand ejection hole 15 '. The hole diameters of both the ejection holes may be the same.

  Three guide plates and three spacers shown in FIG. 3 are laminated on the outer surfaces of the support plate 9 and the inner cylinder mounting plate 11. The first spacer 16 that contacts the support plate 9 and the inner cylinder mounting plate 11 is formed with a circular hole 17 corresponding to the inner cylinder 14, and the first guide plate 18 that contacts the first spacer 16 includes A swirl flow forming hole 20 corresponding to the circular hole 17 of the first spacer 16 and having a notch 19 formed in the vertical tangential direction is formed.

A second spacer 22 having a pair of left and right longitudinal notches 21 is in contact with the outside of the first guide plate 18 at a location corresponding to the tip of the notch 19. On the outside of the second spacer 22, a second guide plate 24 having upper end portions aligned with the pair of cutouts 21 and formed with a through hole 23 that is formed in a generally upward “U” shape. Are in contact.
A third spacer 26 formed with a circular hole 25 is in contact with the outside of the second guide plate 24 so as to overlap a part of the horizontal hole below the through hole 23. On the outside of the third spacer 26, a third guide plate 28 having a water flow supply port 27 for the powder-containing water is in contact with a portion corresponding to the circular hole 25.

The three guide plates 18, 24, and 28 and the three spacers 16, 22, and 26 are integrated with each other by fastening bolts 30 to bolt holes 29 that are respectively drilled. 9 is fixed.
Reference numeral 31 denotes a shielding plate that is joined to the periphery of the turning inner cylinder 14 and whose outer edge is in close contact with the inner wall of the outer cylinder 1.

The point of the refined product-containing water production by the refined product-containing water production apparatus having such a configuration will be described.
Two water streams 32 and 32 'containing a material to be refined, for example, activated sludge, are supplied from the respective supply ports 27 of the left and right third guide plates 28 in FIG. Of these water flows, the left water flow 32 passes through the circular hole 25 of the third spacer 26 and reaches the through hole 23 of the second guide plate 24, where it is divided into left and right as shown in FIG. It is supplied to the longitudinal grooves on both sides of the hole 23. These water flows pass through the notches 21 of the second spacer 22 and are supplied to the leading ends of both notches 19 of the first guide plate 18. Both water flows are supplied at high speed from the tip of the notch 19 to the swirl flow forming hole 20 from the tangential direction, reach the swirl inner cylinder 14 from the circular hole 17 of the first spacer 16, and follow the inner wall of the swirl inner cylinder 14. A swirling flow 34 having bubbles 33 is formed.

The swirling flow 34 reaches the ejection portion 13 at the tip of the inner cylinder 14, and is ejected from the ejection hole 15 toward the other ejection hole 15 'while increasing the speed while contacting the hemispherical inner wall.
Similarly, the water flow supplied from the right supply port 27 reaches the ejection hole 15 ′ as a swirling flow, and is ejected from the ejection hole 15 ′ toward the other ejection hole 15.
The left and right swirling flows 34 collide in the middle of the two ejection holes 15 and 15 ′ in the inner cylinder 14 as a linear water flow. The impact of this collision does not double the speed of the two swirling flows 34, but increases exponentially. Therefore, the bubbles 33 contained in both water streams are refined by impact caused by the stream collision, and at the same time, the powder particles are refined.

Further, unlike the illustrated example, the inner wall of the inner cylinder 14 other than the hemispherical jet portion 13 is inclined inward toward the jet portion 13 to increase the speed of the water flow jetted from the jet holes 15 and 15 '. Also good.
The above-described baffle plate 5 may not be used, and in contrast to promoting the retention of the refined product-containing water generated by the baffle plate, suction from the refined product-containing water outlet 7 with a pump or the like. Then, the removal of the water containing the refined product may be promoted.

The pump 46 is connected to a lake water pumping pipe 47 and a water flow supply pipe 48, and the tip of the water flow supply pipe 48 is branched and connected to a pair of bubbly water flow supply ports 27 of the device 41. .

  When the pump 46 is operated, the lake water is pumped up from the lake water pumping pipe 47 to form gas-liquid mixed water containing air bubbles and supplied to the supply port 27 of the apparatus 41 through the water flow supply pipe 48. The two water streams supplied to the two supply ports 27 collide with each other in the same manner as in FIG. 1 to form a large number of microbubbles 35 and generate refined product-containing water in which the pollutant is refined, This is circulated into the lake 42 from the refined-containing water circulation port 49. This refined product-containing water refines the pollutants in the lake water and promotes decomposition, supplies enriched oxygen to oxidize and sterilize the lake water, and stirs the entire lake water.

Thereby, purification of lake water can be carried out. The energy required for this purification work is only the energy for driving the pump. If the solar panel or wind power generator is loaded on the pit 45 and the energy generated by these is used as the pump driving energy, it is an artificial energy. Without the purification of lake water.
This apparatus does not need to be operated constantly, and may be operated intermittently. In particular, when the obtained hydropower and wind energy are insufficient for regular operation, intermittent operation is preferable.
Also, unlike the example shown in the figure, a pump is installed on the reed 45 without sinking it to the bottom of the lake, and lake water is supplied to this pump to produce water containing fines, and this dissolved water is ejected from between the reed boards into the lake.

Since an outward force is applied to the swirling flow 111 at the time of ejection, and the ejection hole 100 has a certain size, the swirling flow 111 is not only directed toward the other ejection hole 100 but also radially outward. To erupt.
The left and right swirl flows 111 collide in the middle of both ejection holes 100 in the space 101 of the cylindrical main body 91 as a linear or radial water flow. The impact of this collision does not double the speed of the two swirling flows 111 but increases exponentially. Accordingly, the bubbles 110 contained in both water streams are further refined by impact caused by the water stream collision, and the powder particles are also refined.
Further, unlike the illustrated example, the inner wall of the supply pipe 99 other than the hemispherical jet part 98 may be inclined inward toward the jet part 98 to increase the speed of the water flow jetted from the jet hole 100.

11a to 11c are schematic views illustrating other examples of the lid body of the refined product-containing water production apparatus illustrated in FIGS.
11a shows an example in which the number of guide pieces 105a of the lid 103a is two, FIG. 11b shows an example in which the number of guide pieces 105b of the lid 103b is four, and FIG. 11c shows that the number of guide pieces 105c of the lid 103c is five. As an example.
Regardless of which lid 103a-c is used, the water flow supplied to the lid progresses spirally along the outer surface of the guide piece to generate a swirl flow. The swirl flow is most efficiently generated by the lid 103c.

FIG. 12 is a partial longitudinal sectional view showing an example in which a tankless line is connected to the refined product-containing water production apparatus according to the present invention.
A tankless line 124 is connected to the other end of the auxiliary pipe 123 connected to the refined product-containing water outlet 122 of the refined product-containing water production apparatus 121. The tankless line 124 is accommodated in the oil bath 125 and is folded three times in the illustrated example. A heating wire 126 is accommodated in the oil bath 125 to heat the oil in the oil bath 125.
When the wastewater containing, for example, a relatively large-diameter powdery pollutant is supplied to the refined product-containing water production apparatus 121 and ejected from the nozzle and collided as described above, the pollutant is refined and the surface area is increased. , Air dissolves in the waste water as nanobubbles. These nanobubbles come into contact with wastewater and decompose pollutants. In addition, since the nanobubbles are attached to the refined contaminants and float, the contaminants can be floated and separated.
Next, the waste water is led to the tankless line 124 from the refined-containing water outlet 122.
Since the tankless line 124 is maintained at a high temperature and high pressure, the nanobubbles in the wastewater react with the pollutants more efficiently to remove the pollutants almost completely, and can be discharged without further processing.
Since the tankless line 124 is folded back, the tankless line 124 is compact and can perform wastewater treatment with a small installation area.
