Description

  The present invention relates to an apparatus for removing a desired component contained in a gas by absorbing it in a liquid. More specifically, a gas-containing component removing / collecting apparatus that supplies gas to pass through the liquid and removes and collects various desired components contained in the gas while the gas passes through the liquid. About.

  2. Description of the Related Art Conventionally, there is a gas washing bottle (also called a washing bottle) as an apparatus (apparatus) that removes and collects a component contained in a gas by absorbing the component.

  As a conventional gas cleaning bottle, the one configured as shown in FIG. 12 (previous example 1) has been widely known for a long time (see, for example, Non-Patent Document 1). Hereinafter, the configuration and the like of the preceding example 1 will be described.

  As shown in FIG. 12, the gas cleaning bottle 1 of the preceding example 1 includes a liquid storage container 10 made of transparent glass for storing the liquid W, a gas supply tube 11, a gas discharge port portion 12, and a container. 10 receptacle parts 13 (female joints) are provided with glass plugs 14 (male joints) that retain (maintain) airtightness and are detachably fitted. The gas supply tube 11 is formed of a glass plug having both ends opened, and has a gas inlet 15 on the upper end side and a gas outlet 16 at the lower end of the opening.

  The plug 14 is formed of a hollow tapered plug having a taper that opens at the lower end and decreases in diameter toward the lower end. The tube body 11 is provided with a gas inlet portion 15 fixed to the top wall portion 14a of the plug body 14 by welding or the like. The gas discharge port 12 is fixed to the top wall of the plug 14 by welding or the like.

  Prior Example 1 has the above-described configuration. Next, the method of use and operation will be described. As shown in FIG. 12, a liquid W selected according to water, an aqueous solution, or other components to be collected is placed in the container 10 and stored, and the tube body 11 is placed in the liquid W to plug the plug body 14 into the receiving portion 13. Fits airtightly. Then, as shown by an arrow a in FIG. 12, when pressure is supplied from the inlet 15, the gas is supplied into the liquid W from the outlet 16 through the tube 11, passes through the liquid, and moves to the arrow. As shown by b, it is discharged from the outlet 12.

  In the above process, the gas supplied into the liquid from the outlet portion 16 of the tube body 11 forms bubbles and passes through the liquid, and a part of the components contained in the gas (desired desired) The component is absorbed by the liquid and removed.

  As described above, according to the gas cleaning bottle of the first example, the desired component contained in the gas can be absorbed and collected by the liquid. However, in the first example, since the gas is directly fed into the liquid from the outlet portion 16 of the tube body 11, it passes through the liquid as a large bubble. Therefore, since the contact area with a liquid becomes small, it has the problem that the absorption efficiency of a gas containing component is not good.

  Therefore, in order to solve the above problem, as shown in FIG. 13, a gas cleaning bottle 1A (see FIG. 13) in which a glass filter 17 is fixedly attached to the lower end of the opening of the gas supply tube 11 of the gas cleaning bottle 1 of the first example ( Prior example 2) has been proposed and is generally used (see, for example, Non-Patent Document 2).

  In the gas cleaning bottle 1A of the preceding example 2, gas is jetted into the liquid from a large number of fine openings formed in the filter 17, so that the gas is bubbled into small bubbles and passes through the liquid. Therefore, since the contact area with the gas liquid becomes large and the contact time with the liquid becomes long, the absorption efficiency of the gas-containing component can be improved as compared with the first example. However, the prior example 2 has a problem that the filter 17 is likely to be clogged, and in the case that the filter 17 is clogged, there is a problem that the work for correcting the clogging by washing or the like is complicated and takes time and labor. The preceding example 2 is configured in the same manner as the preceding example 1 except that the glass filter 17 is attached to the lower end of the tubular body 11, and therefore, the same components are denoted by the same reference numerals and the description thereof is omitted. .

  As described above, according to the preceding example 2, gas can be generated in small bubbles to increase the contact area with the liquid and the contact time can be increased, thereby improving the efficiency of absorbing and removing gas-containing components. Can do. However, the prior example 2 has a problem that the filter is easily clogged. However, no technology that can solve this problem has been proposed yet.

  By the way, when the component contained in the gas is absorbed and collected by the liquid, depending on the type of the component, the size of the gas bubble (bubble) is passed through the liquid in a large state as in the preceding example 1. Even in this case, the components in the gas may be efficiently absorbed and removed by the liquid. In such a case, the preceding example 1 can suppress the increase in the pressure resistance value on the gas supply side compared to the preceding example 2, so that the gas supply energy can be reduced and the gas-containing component absorption processing time can be reduced. There are cases where it can be shortened. Therefore, it is desirable to be able to adjust the size of the gas bubbles.

  As described above, it can be said that it is ideal to eliminate the problems of the glass filter of the prior example 2 and to adjust the gas bubbling. Therefore, development of the technology is demanded in this industry. However, such a technique has not been proposed yet.
