Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a distillation facility, an absorption facility,
Irregular filling in gas-liquid contacting equipment such as chilled water equipment, water treatment equipment, etc.
The present invention relates to an irregular packing for gas-liquid contact for performing a chemical reaction singly or in any combination thereof, or performing all the processes simultaneously.

[0002]

2. Description of the Related Art Conventionally, distillation equipment, absorption equipment, chilled water equipment,
Filling a gas-liquid contacting material in a gas-liquid contacting device such as a water treatment facility, and contacting a gas and a liquid to perform mass transfer, heat transfer, chemical reaction, etc., alone or in combination, or There was a method in which all processes were performed simultaneously. In this space for gas-liquid contact, without considering the direction and mutual positional relationship of each space in the space inside the gas-liquid contact device,
Ordered packing that is produced as an aggregate of random packing that is randomly inserted and filled, and that is pre-ordered before filling into the gas-liquid contact device so that it is regularly arranged inside the gas-liquid contact device. And exists.

[0003] There are many types of irregular packing such as Raschig rings and Paul rings, and the contact area between a gas and a liquid inside a gas-liquid contacting device such as a distillation column has long been known. It has been widely used as a means of providing. In addition, the flow state of both gas and liquid inside the gas-liquid contact device is greatly affected by the direction of individual packings and the positional relationship between the packings. The gas-liquid contact performance of the entire gas-liquid contact device is determined by the porosity and surface area of the filler,
Various factors, such as the contact area between the filler and the gas-liquid, the flow rate, and the pressure loss rate, are determined by comprehensively acting on the flow state of the gas-liquid.

[0004]

However, since the random packing is irregularly and randomly filled in the apparatus,
Due to the fact that the positional relationship between the packings differs depending on the location,
The porosity also varies depending on the location. in this way,
With random packing, it is in principle difficult to ideally place all of the packing in the apparatus. In such a non-uniform filling state, the gas-liquid flow is biased, and it is difficult to expect an ideal flow state in the gas-liquid contact device. For this reason, there is a limit in realizing high gas-liquid contact performance in a conventional apparatus using random packing.

In order to prevent the gas-liquid contact performance from being reduced due to the disordered arrangement of the packing state in recent years, a structured packing in which all of the packings are in a uniform filling state has been widely used. I have. This ordered packing is manufactured in a block unit in which a predetermined volume of packing is structurally integrated in advance so as to have an ideal arrangement inside the apparatus, and these blocks are arranged in an orderly assembly inside the apparatus. Will be filled.

[0006] The ordered packing as described above is manufactured through many steps, and is processed according to the shape of each device to be used, so that the manufacturing method becomes complicated. for that reason,
Large-scale production equipment for structured packing is economical in large-scale production, but production costs are high in small-volume production for gas-liquid contactors with small tower diameters. It becomes something.

[0007] On the other hand, the random packing is independent of each other without being blocked, so that it can be manufactured relatively easily regardless of the size of the scale. In addition, ordered packing is
Since the ideal filling state can be realized inside the gas-liquid contact device, high gas-liquid contact performance can be expected, but on the other hand, various factors such as uneconomical due to the manufacturing method, unsuitability under individual use conditions, etc. Problems. As a result, ordered packings are not necessarily all superior to random packings.

Another conventional example is disclosed in Japanese Patent Application Laid-Open No. 8-11 / 1996.
There is a filler as described in 0118. This filler is formed by rolling a stainless steel thin wire to form a plate-like member, curling the plate-like member, winding it in a coil in a predetermined direction a plurality of times, and then removing the band-like coil-like plate-like member. By being entangled with each other, a lump-shaped filler body such as a stainless sponge is formed. By filling this into a gas-liquid contact device, a uniform filling state such as structured packing can be realized, and a product can be obtained at low cost.

[0009] However, with this filling, there are operations such as rolling a stainless fine wire and performing a curling process, which requires labor and technology, and lacks productivity. Also,
Since the band-shaped coil-shaped plate-like members are entangled with each other and enter the inside of the coil, the porosity is reduced and an uneven filling state is liable to occur. Therefore, good gas-liquid distribution and contact cannot be performed, resulting in a pressure drop and a decrease in gas-liquid contact efficiency.

Therefore, it would be desirable to be able to produce a packing that is relatively easy to manufacture, such as an irregular packing, and that has some of the packing characteristics of the structured packing. In other words, if it can be easily manufactured at all times regardless of the production volume and the filling state inside the gas-liquid contact device can be filled to some degree in order, and the deterioration of performance due to disorder in the filling state can be minimized, And both performance and performance can be balanced to provide an excellent packing.

[0011] The present invention is to solve the above-mentioned problems, and even if the irregular packing is randomly filled,
It is possible to economically form the inside of the gas-liquid contacting device in a shape capable of intentionally arranging the filling state to some extent. Therefore, by forming the cylindrical irregular packing material such that the ratio of the formation length of the cylinder to the diameter is relatively large, the center of gravity is moved to a high position to easily fall. As a result, most of the irregular packing can be arranged in a state where the cylindrical axis is horizontal or inclined, and the disordered filling state can be alleviated to some extent. In addition, a sufficient open space is ensured even in such an arrangement state, and there is no decrease in the flow area of the gas passing through the irregular packing. For this reason, it is possible to obtain an irregular packing which has a small pressure loss and does not lower the processing capacity.

Another object of the present invention is to improve the production speed by performing a process for producing an irregular packing, which has conventionally been constituted by a large number of discontinuous and complicated processes, by a simple and small number of processes. And by obtaining the irregular packing as described above,
Even if the gas-liquid contacting device is randomly charged, it is intended to achieve a preferable filling state and excellent gas-liquid contact performance.

[0013]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a coil-shaped filling body by winding a band-shaped plate member having a fixed width into a right-handed or left-handed plural times. The two side edges of the plate-like member forming the filling body form a constant opposing interval in the axial direction of the coil, and the opposing interval is the same as the width of the plate-shaped member or the plate-shaped member. The width of the packing body is smaller than the width of the packing body, and the length of the packing body in the axial direction is larger than the outer diameter of the packing body. It is formed by filling a liquid contact device.

Further, the plate member may be formed of any one of a metal material, a plastic material and a ceramic material.

The plate-like member may be formed by slitting a wide plate-like metal material or a wide plate-like plastic material into a plurality of slits.

Further, the plate member may be formed in a smooth flat plate shape.

The plate member may be formed of a net material.

Further, the plate-shaped member has unevenness, a long hole,
Surface treatment may be performed by combining one or a plurality of small holes and grooves.

Further, the filling body may have an axial length ratio to the outer diameter of 1.2 to 3.0.

[0020] The filler body includes a plate-shaped member formed into a right-handed form and a plate-shaped member formed into a left-handed form.
They may be mixed at a ratio of 1.0: 0.8 to 1.0: 1.2.

The filling body may be one in which a plate-shaped member formed into a right-handed form and a plate-shaped member formed into a left-handed form are mixed at a fixed ratio and filled. .

Further, the filling body may be one in which the tip of a plate-like member is bent into the inside diameter of the coil.

[0023]

Since the present invention is constructed as described above, when the irregular packing is filled in a distillation facility, an absorption facility, a chilled water facility, a water treatment facility, or another gas-liquid contacting device, the filling body is Since the length in the axial direction is larger than the outer diameter, the center of gravity is high and it is easy to fall down. The proportion arranged in the inclined direction increases, and the proportion of the axis of the filling body arranged in the vertical direction can be reduced, so that the irregular filling can be filled to some extent. And by setting the length ratio of the axial direction with respect to an outer diameter to 1.2-3.0, the axis | shaft of a filler main body becomes easy to arrange | position the axis | shaft of a filler main body in a horizontal direction or an inclined direction as mentioned above. , With a suitable packing density in the gas-liquid contact device.

By the way, if the proportion of the axis of the filling body in the vertical direction is large, most of the gas easily passes without remaining in the space inside the cylinder of the filling body. In addition, most of the liquid does not stay inside the cylinder of the filling body, but immediately falls in the cylinder, and the liquid does not sufficiently adhere to the surface of the filling body. as a result,
The frequency of contact between the liquid and the gas adhering to the surface of the packing body is reduced, so that mass transfer between the gas and liquid is not sufficiently performed, and the gas-liquid contact ability is reduced. In addition, due to the load generated by stacking of the packing bodies in the gas-liquid contact device, the coil-shaped packing body is compressed and shrunk in the axial direction, and the filling volume is locally reduced, and thus becomes non-uniform. This will make the filling state worse.

However, as described above, the random packing of the present invention can achieve a good filling state because the axis of the packing main body is arranged in a horizontal direction or an inclined direction in many cases.
Further, since the load due to the filling is applied in a direction substantially perpendicular to the cylindrical axis, the coil-shaped filling body is hardly compressed, and the reduction of the filling volume is suppressed. Then, the gas flows into the inside of the filling body through the opposing gaps formed on both side edges of the plate-shaped member of the filling body. As it flows past this opposing distance, the gas splits and then coalesces again in the cylinder. In other words, frequent convergence of the gas through the opposing interval causes turbulence of the gas, increasing the chances of contact with the liquid and acting as a stirring function to improve the gas-liquid contact state. This promotes mass transfer between gas and liquid. In addition, due to the separation and collection of the gas, the gas does not pass through the gas-liquid contact device at a stretch, and the residence time inside the filling body is prolonged. This also improves the frequency of gas-liquid contact.

In the conventional Raschig ring or pole ring, since the open portion of the outer peripheral surface is limited, if the cylindrical shaft is arranged horizontally or inclined, a gap through which gas can flow is hardly formed, and the gas pressure is reduced. Losses may increase and throughput may decrease. In the packing body of the present invention as well, there is a concern that the gas may impinge on the surface of the plate member, thereby increasing the flow resistance and increasing the pressure loss. However, since the packing body has an opposing space, there is no pressure loss that would hinder the processing, and it is possible to obtain irregular packing with excellent gas-liquid contact processing ability. Becomes

On the other hand, the liquid does not flow down all at once in the gas-liquid contacting device, but hits the plate-like member and then drops over a certain time after passing through the facing space while dispersing the surface of the plate-like member. Becomes Therefore, the wet area on the horizontal surface or the inclined surface of the plate-like member is increased, and the effective contact area between gas and liquid is increased. In addition, due to the dispersion effect at the opposing interval, the liquid does not flow at a single point in the gas-liquid contact device and does not drop at a stroke, and the surface of the plate-like member is uniformly moved for a certain period of time. It will flow. When the gas in the turbulent state passes through the packing body to which the liquid is well attached, gas-liquid contact occurs efficiently, and mass transfer is promoted.

Further, if the opposing interval formed on both side edges of the plate-like member of the filling body is formed to be larger than the width of the plate-like member, the surface area per unit area of the filling body decreases, and gas-liquid The contact function is reduced, the load-bearing strength of the filling body is reduced, and the filling state is deteriorated. Furthermore,
Since the filling body is formed in a coil shape, the plate-like member of the other filling body enters into the facing space of one filling body due to vibration at the time of filling or impact due to passage of gas-liquid. In some cases, the filler bodies are entangled with each other and integrated. Then, it is conceivable that a large number of filler bodies are successively combined to form a nodular shape, thereby reducing the filling volume or causing uneven filling.

However, in the packing body of the present invention, the opposing interval is formed to be equal to or smaller than the width of the plate-shaped member. It becomes difficult for the plate-shaped member of the object body to enter,
It is possible to realize a good filling state while preventing a decrease in the filling volume caused by entanglement. However, if the facing distance is too narrow, the open portion of the outer peripheral surface is limited and the gas-liquid flow resistance increases, causing a pressure drop, which may reduce the gas-liquid contact ability. Is preferably not less than one third and not more than the width of the plate-shaped member.

Even when the packing bodies are formed at the opposed intervals as described above, if only the right-handed packing body or only the left-handed packing body is filled in the gas-liquid contact device, it rotates by vibration or the like. At this time, one of the filling bodies enters into the adjacent one of the other filling bodies and becomes entangled with each other, thereby reducing the filling volume of the entire gas-liquid contact device. But,
In the present invention, the filling body is formed by mixing a plate-shaped member formed into a right-handed form and a plate-shaped member formed into a left-handed form at a fixed ratio and filling the mixture into a gas-liquid contact device. Therefore, the probability that the packing materials wound in opposite directions contact each other is increased, and the winding directions intersect with each other, so that the packing materials are hardly entangled with each other. Then, it is possible to realize a good filling state without reducing the filling volume. The mixing ratio of the right-handed and left-handed filling bodies is 1.0: 0.8 to 1.0: 1.2.
The closer to 1.0: 1.0, the lower the probability of adjacent packing bodies wound in the same direction being adjacent to each other, and the more difficult it is for them to be entangled.

Further, the filler body may become entangled with the tip of one plate-like member, and the tip of the other plate-like member may penetrate into the body, and may gradually become entangled by stimulation such as vibration. Therefore, if the tip of the plate-shaped member is bent within the inner diameter of the coil, the tips of the adjacent filler bodies do not come into contact with each other, and the effect of preventing entanglement with each other is further improved. It will be.

If the plate-like member is formed of a metal material, a plastic material or a ceramic material, it is possible to easily cut or form it into a coil shape, and to provide a filling material excellent in load resistance. The main body can be formed inexpensively.

Further, if the plate-like member is formed into a smooth flat plate, the working operation is simple and the production cost is low. Further, if the plate-like member is formed of a mesh material, the gas-liquid dispersion effect is enhanced by the gas-liquid passing through the mesh.
Further, since the net material itself has a wetting effect, the amount of liquid staying in the plate-like member increases, and the gas-liquid contact performance can be improved.

The plate-like member has a surface with irregularities, slots,
If surface treatment is performed by combining one or more of small holes and grooves, it takes more time than forming a flat plate or using a net material, but improves the gas-liquid dispersion capacity. Or increase the surface area of the plate-shaped member.
The effective contact area is increased by the liquid wetting effect on the surface of the plate-shaped member, and efficient gas-liquid contact is enabled.

[0035]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. (1) is a plate-like member which is formed by slitting a wide stainless steel plate having a thickness of 0.2 mm to a width of 3.0 mm. It is formed. Then, this plate-shaped member (1) is made to have an outer diameter of 15.0.
As shown in FIG. 1, a coil-shaped filling main body (2) having a length of 27.0 mm in the axial direction is formed as shown in FIG. Therefore, the axial length becomes longer than the outer diameter, and the axial length ratio to the outer diameter is:
1.8 times. Further, as shown in FIG. 2, the filling body (2) forms a constant opposing interval (3) in the axial direction by both side edges of the plate-like member (1) wound in a coil shape. The facing interval (3) is set to 3.0 mm which is the same width as the plate-like member (1).

As described above, the first step of forming the plate member (1) by slitting the stainless plate material, the second step of winding the plate member (1) in a coil shape, The third step of cutting the shaped member (1) one after another at a constant length constitutes a step of producing the irregularly packed material (4). First
The formation of the plate-like member (1) by the slit processing in the process can be performed continuously, and a large number of the members can be formed at once and easily. Further, the second step and the third step include a plate-shaped member.
While winding (1) in a coil shape and simultaneously cutting the coil-shaped plate-shaped member (1) one after another to a predetermined length, the work is integrated and the filling body (2) is continuously formed. Can be manufactured. As a result, the production of the irregular packing (4) can be easily performed in a series of operations, and the production efficiency is improved. In addition, since each work process is simple and does not require expensive equipment, the cost reduction effect is large.

As another different method of manufacturing the packing body (2), a stainless steel plate material corresponding to the length required for one packing body (2) is prepared. Then, in the first step, this stainless steel plate is slit into a narrow width direction,
One plate-like member (1) is obtained. Thereafter, in a second step, the plate-like member (1) is wound in a coil shape to obtain a filling body (2). According to this method, the operation of separating the coil-shaped plate-like members (1) one by one for each filling body (2) can be omitted, and the manufacturing method can be simplified.

The right-handed filling body (2a) as described above
With the same material, dimensions and manufacturing process as in
(1) is wound, and as shown in FIG.
(2b) is formed.

Then, the irregular packing formed as described above
(4) is appropriately filled in a gas-liquid contact device (not shown). This filling is performed by a right-handed packing body (2a) and a left-handed packing body.
(2b) is uniformly mixed at a ratio of 1.0: 1.0. By the way, if the axis of the filling body (2) is arranged in the vertical direction, the filling load causes the coil-shaped filling body (2) to shrink in the length direction, and the entire gas-liquid contact device becomes Although the filling volume is reduced, the filling body (2) of the present invention is formed so that the length in the axial direction is larger than the outer diameter, so that the center of gravity is increased, and the gas-liquid contact device is turned over. Inside, as shown in FIG. 4, the axis of the filling body (2) is arranged in a horizontal direction or an inclined direction.
And since the filling main body (2) is excellent in load resistance in the width direction of the cylinder, the filling main body (2) does not collapse due to the load due to filling, and the filling state does not change due to the load. It will be.

Further, in the filling body (2), the opposing interval (3) of the plate-like member (1) is formed to be the same as or smaller than the width of the plate-like member (1). Even if it receives the stimulus of this, in this opposed space (3), the other filling body (2)
The inconvenience that the plate-shaped members (1) intrude and enter each other can be solved. In addition, the right-hand packing body (2
Since a) and the left-handed filling body (2b) are mixed at a ratio of 1.0: 1.0, there is a high possibility that two coils having different coil winding directions are adjacent to each other. Then, since the winding directions are opposite to each other, it is possible to more effectively prevent the adjacent filling bodies (2) from entering each other, and to realize a good filling state in which a large number does not become a lump. Become.

When the gas-liquid contact is performed in the gas-liquid contact device filled with the irregular packing (4) as described above, the gas hits the coil-shaped plate-like member (1). Although flow resistance is generated, since the flow path is provided by the opposed distance (3), the opposed distance can be reduced without causing a pressure loss.
While passing through (3) and being stirred, it flows into the inside of the filling body (2). On the other hand, if the facing distance (3) is too wide, the gas will quickly pass through the inside of the filling body (2) without receiving the flow resistance, and the gas-liquid contact capability may be reduced.

On the other hand, if the facing distance (3) is too narrow, the flow resistance increases, the pressure loss of the gas becomes remarkable, and the gas-liquid contacting ability also decreases. However, in this embodiment,
By forming the facing gap (3) to be the same width as the plate-like member (1) and about half the surface area of the packing body (2), the gas receives moderate flow resistance, and ) Since the gas passes through the inside of the packing body (2), the inside of the packing body (2) is sufficiently agitated, so that the chance of contact with the liquid is increased and the pressure loss of the gas is effectively suppressed.

Further, the gas is divided by the coil-shaped opposing interval (3), flows into the inside of the filling body (2), and is integrated again therein, and then dispersed again from the opposing interval (3). leak. This frequent separation and dispersion of the gas causes turbulence of the gas. And this turbulence acts as a stirring action,
It effectively promotes mass transfer, heat transfer, and chemical reaction by gas-liquid contact.

The liquid flows into the packing body (2) while flowing on the surface of the plate-like member (1) or while being dispersed in the circulation path at the circulation interval (3). Therefore, the liquid does not flow down at once, but flows through the gas-liquid contact device while a certain period of time passes, and the frequency of contact with the gas increases. Further, since the filling body (2) is arranged with its axis being horizontal or inclined, the liquid easily adheres to the surface of the plate-like member (1), stays on this surface for a long time, and comes into contact with gas-liquid. This increases the effective wetting surface area.

Further, the filling body (2) of the first embodiment is described.
By filling the gas-liquid contacting device with the facing space (3) having the same width as the plate-like member (1) or by mixing materials having different winding directions, the packing bodies (2) are Good prevention of entanglement. However, it cannot be said that the packing bodies (2) wound together in the same direction are adjacent to each other.
In this case, the tip of one plate-like member (1) is connected to the other plate-like member.
By entering the inside of the tip of (1) and applying a stimulus such as vibration in this state, there is a possibility that these filling bodies (2) are entangled and integrated with each other to deteriorate the filling state.

Therefore, in another different second embodiment, as shown in FIG. 5, both ends of the plate-like member (1) are bent into the inner diameter of the coil to form the filling body (2). I have. Then, even if the cylinders of the filler body (2) come into contact with each other, the tips of the plate-like members (1) do not come into contact with each other.
The effect of preventing entanglement is further improved.
In this embodiment, since the inner diameter of the coil is 15 mm, the plate-like member (1) is bent inward at a length of 10 mm from the front end so that the front end can be arranged within this inner diameter. .

In each of the above embodiments, the plate-like member (1) is formed of a stainless steel plate. However, the plate-like member (1) may be formed in accordance with the application, performance, corrosion resistance to gas-liquid components, and budget. Carbon steel, copper, aluminum, titanium, other metal members,
It may be formed of plastic, ceramic, or the like.

The plate-like member (1) is formed by slitting a wide plate-like metal material or a wide plate-like plastic material. Alternatively, a wide plate-like net material may be used. A plate-shaped material is excellent in economical efficiency, and the manufacturing operation is simple and easy. If a net material is used for the plate-like member (1), numerous holes are formed by the net material on the surface of the plate-like member (1), so that a good wetting effect due to the surface tension of the liquid occurs. In addition, since the surface area where gas-liquid contact is possible is increased, it is possible to obtain an irregular packing (3) having excellent gas-liquid contact ability.

The plate-like member (1) may be formed by subjecting the surface to surface processing by combining one or more of irregularities, long holes, small holes, and grooves. Good gas-liquid contact is enabled by increasing the effective surface area for the gas-liquid contact of 1).

The ratio of the length in the axial direction to the outer diameter of the filling body (2) is desirably 1.2 to 3.0 times.
If the length ratio is smaller than 1.2 times, the center of gravity of the packing body (2) becomes lower, so that the ratio of the horizontal or inclined arrangement of the shaft is reduced, and the gas-liquid contact ability is deteriorated. On the other hand, if the length ratio is larger than 3.0 times, the degree of density in the filling state in the gas-liquid contact device becomes remarkable, and the filling state deteriorates.

Using the coiled random packing of the present invention and a conventional pole ring, a comparison of pressure loss was conducted in a total reflux distillation experiment, and the results are shown in FIG. Note that Co_15 shown in the table is a coil-shaped irregular packing of the present invention, and is formed with a diameter of 15 mm using a stainless member having a thickness of 0.1 mm and a width of 3.0 mm.
PR_15 is a pole ring made of a stainless steel member and has a cylindrical diameter of 15 mm.

From the results of the experiment, it was found that Co_15 of the present invention had a smaller pressure loss, despite having the same diameter, between Co_15 and PR_15. Therefore, it can be seen that the irregular packing of the present invention is an excellent product with low pressure loss.

In addition, in the two kinds of irregular packings used in the experiment of FIG. 6, a comparison of HETP showing the filling height per one theoretical plate was carried out, and the results are shown in FIG. .

From the experimental results, it was found that the Co_15 of the present invention had a much smaller HETP than that of Co_15 and PR_15. Therefore,
The irregularly packed material of the present invention has a low filling height per theoretical plate and exhibits excellent gas-liquid contacting ability, and it is understood that the product is excellent in economical efficiency from the viewpoint of performance.

[0055]

Since the present invention is constructed as described above, even if the irregular packing is randomly filled in the gas-liquid contacting device, the majority of the axis of the coil-shaped packing body is horizontal. Alternatively, they can be arranged at an angle, and almost all can be arranged regularly. As a result, the gas-liquid passes through the inside of the filling body, passing through the coil-shaped opposing interval formed by both side edges of the coil-shaped plate-shaped member of the filling body. When the gas passes through the opposing interval, the gas repeatedly splits and coalesces, so that turbulence of the gas is generated, and the contact ability with the liquid is improved. Also,
The liquid also disperses and flows, and easily adheres to the surface of the plate member, and the wetting effect is improved. The gas which repeats such frequent separation / dispersion and the liquid dispersed in the plate-shaped member are in good contact with each other, so that mass transfer, heat transfer and chemical reaction between gas and liquid can be remarkably promoted.

Further, by being arranged horizontally or inclined, the filling body is not crushed by the load.
In addition, the right-handed and left-handed filling bodies are mixed at almost the same ratio, and the facing distance between the plate-like members of the filling body is formed to be equal to or smaller than the width of the plate-like member. The object bodies do not become entangled with each other, and a uniform and good filling state can be realized. Therefore, the gas pressure loss is suppressed, the gas-liquid drift is prevented, and the gas-liquid contact capability is improved.

Further, it is possible to easily form the filler body simply by winding the plate-shaped member. And, without being restricted by the size of the diameter, it can be formed freely even with a small diameter or a large diameter, and there is no need to match the size of the gas-liquid contact device,
It is possible to form an irregular packing at low cost by a simple manufacturing process.
