液体の中に捕捉されるようにした方法がある。Techniques for collecting particles suspended in a gas to separate them from the gas can generally be broadly classified into a filtration method, a cyclone method, an inertial precipitator method, and an electrostatic precipitator method. The filtration method is a method in which particles are deposited on a filter by passing a dust-containing gas through the filter. The cyclone method is a method of centrifugally separating gas and particles by applying centrifugal force to dust-containing gas. The inertial dust collection method is a method in which dust-containing gas collides with a wall or liquid surface at high velocity, and particles are attached to the wall or collected in the liquid. Further, the electrostatic precipitation method is a method in which suspended particles are charged and attracted to an electrode. In addition to these conventionally used methods, the dust-containing gas is dispersed as fine bubbles, and all suspended particles are trapped in the liquid by impacting the surface of the bubbles with a bran motion. There is a way.

電しにくい粒子には適用できないという欠点がある。Among the above-mentioned methods, the filtration method, cyclone method, and inertial dust collection method are the kings.If the particle size is large, the dust collection effect is large, but as the particle size becomes smaller, the dust collection becomes more difficult. Regardless of the method, particles with a particle size of 0.1 μm or less are almost impossible to collect. Furthermore, the electrostatic precipitator method has the disadvantage that it cannot be applied to particles that are difficult to charge.

された。In order to overcome the above drawbacks, a gas containing suspended particles is introduced into a liquid, and the suspended particles are dispersed as fine bubbles by vigorous stirring. Recently, a method has been invented which allows particles to collide with the interface between particles and gas, and which can sufficiently collect particles of any type, even ultrafine particles with a particle size of several nanometers or less.

能な、新規な方法と装置を提供するのを目的とする。However, this method requires that the gas containing the particles to be collected be dispersed in the liquid as fine bubbles, so a high-speed rotating stirrer is used for this purpose, and a considerable portion of the energy is converted into heat, resulting in this As the temperature of the liquid increases, it becomes easier to vaporize, and some of the collected particles are released into the gas. In addition, this method is mechanically difficult to scale up. In view of the above, the present invention has been developed by
It is a new technology that can separate fine particles with a wide range of particle sizes from a few nanometers or less from gases, does not re-emit the collected particles, consumes less energy, and can be made larger. The purpose is to provide a method and apparatus for

Gas A containing suspended particles is introduced from the gas inlet 4 at the lower end of 1, and is passed through the filled part of the breathable porous body M, thereby collecting the suspended particles in the liquid. The gas from which suspended particles have been removed is obtained from the exhaust port 2 at the upper end.

い気体が得られる。The tube 1 has an exhaust port 2 and a liquid inlet 3 at its upper end, and a gas inlet 4 and a drain port 5 at its lower end, each of which has a stopcock. An air-permeable porous material M is filled in a portion from a portion slightly above the lower end of the tube 1 to the upper portion of the tube. A liquid that thoroughly wets the porous body M is injected from the liquid injection port 3 so that the porous body M is sufficiently immersed and a slight liquid layer is present on it. The liquid injection port 3 and the liquid drain port 5 are closed, the exhaust port 2 is left open, and the gas A containing suspended particles is introduced by opening the gas introduction port 4. Gas A passes through the filled part of the porous body M, reaches the upper part of the pipe 1, and is discharged to the exhaust port 2. During this time, suspended particles in the gas A move into the liquid, and are discharged from the exhaust port. 2 yields a gas free of suspended particles.

体りによって、とり囲まれていることになる。Gas A introduced from the gas inlet 4 passes through the porous body 4, which is immersed in the liquid, but the porous body M passes through the second porous body M.
As shown in the schematic vertical cross section of the figure, many capillaries are arranged in a three-dimensional structure, and the introduced gas forms a large number of fine bubbles B and passes upward through the capillaries. . Since the porous body M is easily wetted by liquid, the inner surface of the pores of the porous body M that is immersed in the liquid is covered with the liquid, and all the air bubbles B that have entered the porous body M are surrounded by the liquid. , will be surrounded.

さいほど活発である。In order for the particles suspended in the gas A to move from the bubble B into the liquid and be collected, the particles need to come into contact with (collide with) the liquid surrounding the bubble B. Floating particles generally perform Brownian motion, and the smaller the particle size, the more active this motion is.
従って気泡に閉じこめられた粒径の小さい粒子は、大き

Each of these four ports has a stopcock, and when all these stopcocks are closed, the tube 1 is sealed. A position 6 slightly above the lower end of the tube 1 and a position 7 slightly below the upper end of the tube 1 are configured so that a coarse mesh N can be held horizontally. The net fixed at position 6 is filled up to the position of the breathable porous body Mt7, and the top is pressed down with the net to hold this net at position 7.

得られた。In the above embodiments of the present invention, the exhaust port 2 and the liquid injection port 3
3, and inject a liquid that thoroughly wets the porous body M from the liquid injection port 3, immersing the porous body M, and leaving a slight liquid layer on the mesh at position 7. . Close the liquid injection port 3, open the gas introduction port 4, and pressurize the gas A, or suck it from the exhaust port 2 to remove the gas A.
is introduced into the lower part of the tube 1, and further into the part filled with the breathable porous material M. Gas A is divided into fine bubbles by the porous body M, but since the liquid is selected to wet the porous body M well, all the walls of the pores of the porous body M are covered with the liquid, and the bubbles are is not in direct contact with the wall surface of the porous body M, but is surrounded by the liquid. When particles suspended in a gas come into contact with a liquid, they are taken into the liquid and exhibit a so-called cleaning and dust collection effect, but the particles suspended in the air bubbles are moved to the walls made of the liquid due to Brownian motion. You will have an Isokai that you will be in contact with. For all the suspended particles in the bubbles to move into the liquid,
In the case of large, long and thin bubbles, it is necessary that the diameter of the bubbles be sufficiently small and that the residence time in the liquid is sufficient. Even relatively large suspended particles can be almost entirely transferred to the liquid while passing through the porous body Mt. Porous body M
The size of the bubbles passing through and the residence time in the porous material
" is determined by the size of the pores of the porous body and the amount of gas A introduced per unit time, but the diameter of the pores of the porous body M and the amount of gas A introduced per unit time can also be controlled. quantities, and therefore by controlling these quantities,
Almost all of the suspended particles in the bubble B are transferred to the liquid, and it is possible to completely separate and collect them. In this example, the pressure difference between the exhaust port and the gas inlet port was approximately 300 mmAq, and the device was operated normally and the expected results were obtained.

力の落ちた部分を。If the concentration of particles collected in the liquid held in the porous body M by passing the gas A becomes high and the ability of the liquid to collect suspended particles decreases, the liquid is injected from the liquid injection port 3. While pressurizing the liquid, open the liquid drain port 5 and drain the area where the liquid collection ability has decreased.

In addition to the substance, the tube 1 is filled with sand, chips, or fibers, or the tube 1 is filled with thin columnar bodies or capillaries in parallel in the length direction of the tube 1. It can be used as M.

方法はほとんどすべての質の粒子の分離に適用できる。In order to sufficiently collect suspended particles in gas A in liquid,
A liquid that easily wets the surface of the suspended particles is selected as the liquid, but the liquid must be able to wet the inner wall surfaces of the pores of the porous body M well. Therefore, it is necessary to select the liquid and the porous body M depending on the surface chemistry of the suspended particles to be removed from the gas. If this choice is appropriate, the method of the invention can be applied to the separation of almost any quality of particles.
また液体りの性質によっては、浮遊粒子を除去できるだ

去することもできる。Also, depending on the properties of the liquid, it is possible not only to remove suspended particles, but also to remove some gaseous components (for example, sulfur oxides and nitrogen oxides in the air) from gas A by absorbing them into the liquid. .

も、この通気性多孔体を貫通している孔の径は。Note that the method and device of the present invention look similar to filtration and filtration devices, but as shown in FIG. Alternatively, as shown in FIG. 4, a certain degree of clogging of the filter makes it possible to trap even particles smaller than the mesh of the filter. On the other hand, even though the breathable porous body of the present invention is similar to a filter body used in filtration, the diameter of the pores penetrating this breathable porous body is small.
捕集すべき粒子の径に比してはるかに大ぎく、多孔体そ
のものが直接捕集すべき粒子の通過を阻止するものでは
なく１本発明の方法および装置は濾過とは全く作用機構
を異にするものである。The diameter of the porous material is much larger than that of the particles to be collected, and the porous body itself does not directly prevent the particles from passing through.The method and device of the present invention have a completely different mechanism of action from filtration. It is something to do.

が可能であり。As explained above, according to the present invention, the gas in which the particles to be collected are suspended is passed through an air permeable porous body immersed in a liquid to increase the chances of each particle coming into contact with the liquid. One particle can be collected and separated in a liquid, and by selecting an appropriate liquid, particles of almost any quality can be collected.
