に使用目的が限定されていた。In a pump device that obtains a pressure head by generating bubbles by giving latent heat of vaporization to a liquid, the energy required for evaporating the liquid is enormous. Because it is used as an additional effect of heat transfer rather than the function of
When viewed as a pump, the entire apparatus becomes large and wastes energy. In addition, since heat transfer is always involved, it is difficult to control the temperature of the liquid itself, and when it is applied to a low-temperature liquid, it may not function as a pump. Therefore, the bubble diameter and bubble amount that determine the capacity of the pump cannot be arbitrarily controlled, and the purpose of use has been limited to special applications.

の総合効率としては非常に低いものであった。A device for dissolving a gas under pressure in a liquid and then depressurizing it to obtain fine bubbles requires a large tank device for pressurizing the gas and the liquid. In order to dissolve a large amount of gas, the energy required for pressurization was also large, and the overall efficiency of the pump was very low.

置に関するものである。The inventor of the present invention specifies a structure of the surface opening of a bubble dispersing mechanism in a gas mixing and mixing apparatus for mixing a gas into a liquid, thereby stably dispersing and mixing a large amount of fine single bubbles into the liquid. It has been found that the momentum of the gas can be efficiently and reliably transmitted to the liquid. The present invention is based on such knowledge, by dispersing and mixing a large amount of fine bubbles in a liquid,
TECHNICAL FIELD The present invention relates to a pump device that functions efficiently by reliably and efficiently increasing the momentum of a liquid to greatly increase the speed of the liquid.
【０００７】液対中に単に気体を混入させただけでは、
気体を大量に混入させた場合の気液二相流の流動様相は
スラグ流あるいは環状流となり、液体速度よりも気体速
度が非常に大きく液体への運動量伝達が有効に行われな
い。[0007] If a gas is simply mixed into a liquid pair,
The flow aspect of the gas-liquid two-phase flow when a large amount of gas is mixed is a slug flow or an annular flow, and the gas velocity is much larger than the liquid velocity, and the momentum transfer to the liquid cannot be performed effectively.

流れ去る。このような状態では液体の速度が上昇しない
ばかりか、液体のみの単相流と比較して気体塊が存在す
ることにより圧力損失が増えるために失うエネルギーも
大きくポンプ効率も低い。As described above, since the conventional gas mixing mechanism has no means for making a large amount of gas fine and dispersing it uniformly in the liquid, the flow pattern after mixing becomes an annular flow or a slag flow, and the gas flows from the gas to the liquid. Momentum transfer by shearing does not proceed, and the gas flows away faster than the liquid while maintaining a large velocity. In such a state, not only the speed of the liquid does not increase but also the energy lost due to the increase in pressure loss due to the presence of the gas mass compared with the single-phase flow of the liquid alone is large, and the pump efficiency is low.

固体伝播振動や固体伝播騒音を発生させていた。In the case of slag flow and annular flow, the gas and liquid phases are completely independent, and in the case of spray flow, the liquid phase having energy is finely separated. Generates large vibrations and noises, and when transported by pipes, the vibrations wear down the walls and generate unnecessary solid-borne vibrations and noises.

ンプ装置を提供することが可能である。The present invention has been made to solve the above problems, and an object of the present invention is to efficiently and reliably increase the speed of a liquid by mixing and dispersing a large amount of gas in a fine form in the liquid. It is possible to supply a liquid that can be washed in the same manner as in the case of washing only with a conventional liquid by providing the ejected liquid in a well-controlled continuous flow while increasing the amount of liquid to be saved, and furthermore, It is an object of the present invention to provide a bubble pump device capable of performing these operations with low energy loss and high efficiency. Further, according to the present invention, a stable continuous bubble flow that does not exhibit unstable behavior like a slag flow, an annular flow or a spray flow does not generate unnecessary vibration or noise. In addition, since a large amount of fine bubbles are dispersed in the liquid, the contact area between the gas and liquid is very large and the flow appearance is stable, so that it can be used as a field for chemical reaction or physical dissolution. At the same time, since it functions as a highly efficient bubble pump, it is possible to provide a bubble pump device that can operate at a low driving pressure.

It is an object of the present invention to provide a bubble pump device that operates with high efficiency with little energy loss by reliably transmitting the momentum of gas to the liquid to provide the liquid in a well-controlled continuous flow.

作動する気泡ポンプ装置を得ることができる。In the first and second aspects, a bubble dispersing mechanism is provided for mixing gas into the liquid. Therefore, while the gas mixed in the flowing liquid becomes bubbles, the surrounding bubbles are maintained while maintaining the closed cells. Can be suppressed. If the coalescence of bubbles is prevented, the momentum of the gas can be transmitted to the liquid without forming a slag flow, an annular flow or a spray flow, so that a highly efficient bubble pump device can be obtained.

Since fine bubble supply means for supplying fine bubbles of m to 1000 μm into the liquid is provided, the rigidity of the bubbles is high and the bubbles are hardly deformed, so that it is possible to obtain a stable bubble flow which does not easily cause the coalescence of the bubbles, Since unnecessary movement is not caused, energy loss is small and noise and vibration can be prevented. Further, since the gas-liquid contact area can be increased, it is possible to provide a physical dissolution in which a gas is dissolved in a liquid or a place for performing a chemical reaction between a gas and a liquid.

ある。According to the fourth aspect, since the opening of the surface of the bubble dispersing mechanism which is in contact with the liquid is constituted by a large number of independent openings, the gas mixed in the flowing liquid becomes bubbles while the bubbles are mixed. , And coalescence with surrounding bubbles can be suppressed. Further, the bubbles grow to a predetermined bubble diameter, and when the shearing force of the flowing liquid exceeds the force generated by the interfacial tension of gas-liquid acting in the opposite direction to this shearing force, the bubbles are dispersed in the bubbles. Dissociates from the opening of the mechanism and disperses in the liquid. The bubbles diffuse due to the turbulence of the flow and are uniformly dispersed in the tube, but in the process of dispersing the bubbles in the flowing liquid, the moving speed of the unburied fine bubbles quickly becomes almost the same as the liquid speed, and the speed of the liquid Increases with conservation of mass. In addition, the shape of the bubble having a small diameter is close to a sphere and the rigidity is high, so that deformation and coalescence hardly occur, and the bubble is diffused into the flowing liquid as a single bubble. In this manner, by generating fine bubbles in the gas mixing and mixing apparatus and simultaneously mixing them with the liquid, it is possible to quickly transmit the momentum of the gas to the liquid side and to function as a bubble pump without loss of energy.

The gas is mixed, miniaturized, dispersed, and mixed with the liquid supplied from the liquid pipe 2 in the bubble dispersing mechanism 5 at the same time. A gas chamber 3 is provided in the bubble dispersion mechanism 5, and gas is supplied to the gas chamber 3 from a gas introduction pipe 4. At this time, the gas chamber 3 functions as a buffer region for absorbing pressure fluctuation and pressure distribution. A large number of independent openings are provided on the surface of the bubble dispersing mechanism 5 which is in contact with the liquid, and the bubbles are miniaturized by the shear force of the liquid. The bubble dispersing mechanism 5 forms a part of the wall of the liquid pipe, is provided on the entire circumference of the wall of the pipe, and is provided so as to extend in the direction of the liquid pipe, so that turbulence and stagnation of the flow are not generated. Since the opening area can be increased and the bubble generation density at the opening is low, even if a large amount of gas is mixed, bubble coalescence is hardly generated during bubble generation, and fine closed cells can be generated, so the gas pressure Momentum can be reliably, efficiently, and quickly transmitted to the liquid. In addition, fine bubbles have high rigidity and are not easily deformed, and do not perform unnecessary movement, so that energy loss is small. Note that P represents pressure, V represents speed, Q represents flow rate, and ρ represents density, and the subscript w represents the state of the liquid, and the subscript a
Represents the state of gas, and the suffix t represents the state of gas-liquid two-phase flow. However, Pa excludes the gas pressure loss when passing through the bubble dispersion mechanism, and ignores the kinetic energy of the gas because the density of the gas is negligibly small compared to the density of the liquid.

んど無いことから液体への適用にも適している。As shown in FIG. 2, the surface when filled with substantially spherical particles of ultra-high molecular weight polyethylene and heat-molded has independent openings in which the voids are divided by the particles.
It is suitable for generating closed cells. In addition, by filling the particles with substantially uniform particles, the openings are arranged regularly in a substantially lattice shape, and bubbles are less likely to coalesce at the time of generation. In addition, ultra-high molecular weight polyethylene generally has a low melt index (MI) and hardly flows even in a molten state because the property at the time of melting is close to that of rubber, so that particles have a structure in which only the contacts are bonded without changing the shape. . The MI of the ultrahigh molecular weight polyethylene used here is 0.2 to 1.0, which is about 1/10 of that of a normal resin material for injection molding. Are melted at a temperature slightly higher than the melting point of the spherical particles, so that the spherical particles are formed in a shape almost close to point contact. Since the structure is such that only the contact points are fused, the surface shape is almost determined by the shape, particle size distribution, and filling factor of the raw material particles. ing.
Further, since it is chemically stable, it is suitable for a cleaning liquid containing chlorine, an acid base, an organic solvent, and the like, and is also suitable for application to a liquid because it has almost no hygroscopicity.

にかけることも望ましい。FIG. 3 shows a case where substantially spherical particles of an acrylic resin are heated. Although the particles have a slightly high fluidity, the particles are bonded to each other to form independent openings having a structure close to a network structure. It is. In addition, by filling the particles with substantially uniform particles, the openings are arranged regularly in a substantially lattice shape, and bubbles are less likely to coalesce at the time of generation. The acrylic resin has a low surface tension and a high affinity for liquid. Further, if the particle size distribution is uniform, the pore diameter is likely to be uniform, and the pore shape is easily controlled. Therefore, it is desirable that the particles are sieved before heat molding to uniform the particle size distribution.

In addition, dust and precipitated components in liquids and gases are less likely to adhere.

Although the average particle diameter of the particles is 50 μm to 300 μm, the pore diameter can be controlled by controlling the particle diameter of the material. Therefore, the bubble diameter of generated bubbles is determined by the average particle diameter of the material. When the particles having an average particle diameter of 50 μm to 300 μm are used, pores for forming a bubble diameter of 100 μm to 1000 μm are formed. To increase the cell diameter, the particle diameter of the material may be increased, and to decrease the cell diameter, the particle diameter of the material may be decreased.

A substantially lattice-shaped regular aperture arrangement can be obtained. In addition, because the fiber diameter and spacing can be set arbitrarily,
It is suitable for controlling the surface shape such as the inter-pore distance, the pore diameter and the porosity. If a fiber material is used, stable operation can be ensured by installing it on a support because the fiber itself usually does not have sufficient strength, and since the fiber surface slightly vibrates due to the flow, bubble generation and local There is also an effect that the amount of mixed gas changes to prevent adhesion of dust, scale, and the like in the liquid. In addition, since the fiber material does not have a sufficient thickness, the pressure fluctuation of the liquid is likely to be transmitted to the gas chamber, causing unstable behavior when mixing the gas, and may cause vibration.To avoid vibration, stack several sheets This is preferable.

A large amount of fine bubbles are contained in the liquid, and the bubbles themselves are contained so as to be protected by the liquid.Therefore, they do not easily interfere with the atmosphere even after being released to the atmosphere. It is possible to reliably transmit the increased momentum of the liquid without releasing the velocity after the discharge. The flow after ejection of the microbubble flow shows the same behavior as when it is ejected with only liquid, and unlike slag flow, annular flow and spray flow, there is little generation of scattering, vibration, noise, and excellent use environment .

The equivalent diameter of the bubbles changes depending on the liquid flow velocity. When the liquid flow velocity is high, the shear force is large and the bubble diameter is small, and when the liquid flow velocity is low, the relation that the bubble diameter is large due to the small shear force is obtained. I have. From this, it is possible to control the generated bubble diameter by changing the liquid flow velocity at the time of bubble generation. When the effect of the shearing force is the same, the generated bubble diameter is roughly proportional to the opening area of the surface of the bubble dispersion mechanism that is in contact with the liquid. Good.

Db represents the bubble diameter at the time of generation, D represents the bubble diameter when the residence time is changed, and D / Db represents how many times the bubble diameter is larger than that at the time of generation. I have. As the residence time increases and the bubble diameters unite and grow, the bubble diameter can be controlled by controlling the residence time. Also, by changing the flow rate, the bubble diameter and bubble growth during bubble generation can be controlled, so a large bubble diameter can be obtained when the flow rate is small, and a small bubble diameter can be obtained when the flow rate is large. It is possible to control the vibration frequency generated when the vehicle collides. Further, the growth of the bubble diameter can be controlled by applying a turbulent strength or a centrifugal force, but it is possible to promote the coalescence of the bubbles and obtain a large bubble diameter by bending or bending the pipeline after the bubbles are generated.

A large number of independent openings are provided on the surface of the bubble dispersing mechanism that is in contact with the flowing liquid, so Since mixing, miniaturization, dispersion, and mixing are performed simultaneously, mixing of gas into the liquid and transmission of momentum are reliably performed, and the effect of increasing momentum is extremely high. Further, by simultaneously performing these, the input energy required is very small. When the gas mixing ratio exceeds approximately 4, the gas flow transitions from a bubble flow to an annular flow or a spray flow, so the momentum increasing effect decreases and noise and liquid splash increase, so the operating conditions were set to a gas mixing ratio of 4 or less. Is more desirable.

The bubble dispersing mechanism 10 is configured by heating and welding a nylon mesh 12 having independent openings to a support 11 and has sufficient strength. The opening shape of the mesh 32 is determined by the thickness and spacing of the fibers used. Can be adjusted arbitrarily. If the gas supply is stopped during operation, part of the liquid may enter the gas side pipe through the opening due to the pressure due to the osmotic pressure of the liquid or the pipe resistance. Even when only the liquid is supplied, it is desirable to pressurize the gas side so that the gas slightly flows into the liquid, so that the liquid can be prevented from entering the gas-side pipe.

Therefore, a large amount of air bubbles can be stably mixed with the liquid. The momentum of the liquid can be surely increased with little input energy without flowing,
The liquid saving effect is high. Note that the bubble diameter varies depending on the residence time after bubble generation, but after the momentum of the gas is reliably transmitted to the liquid and the speed of the bubble and the speed of the liquid become substantially the same, the gas has almost all energy. Since the behavior of the gas such as the bubble diameter does not affect the liquid saving rate because there is no bubble, it is desirable to provide different cleaning by utilizing the difference in feeling of use due to the difference in the bubble diameter.

を４以下とした方が望ましい。FIG. 10 is an example showing the bubble pump effect in this embodiment. Et / Ew indicates an energy amplifying effect, Et represents the output energy of the fine bubble flow on the downstream side of the gas mixing and mixing apparatus, and Ew is the energy of the liquid on the upstream side of the gas mixing and mixing apparatus. Efficiency is E
It is expressed by t / (Ew + Ea), and is the total efficiency as a pump obtained by dividing output energy by all input energy. ｛Where Ew = PwQw + (ρw / 2) QwVw 2 , E
t = PtQt + (ρt / 2) QtVt 2 , Ea = PaQa, P is pressure, Q is flow rate, ρ is density, V is velocity, and the subscript w is when gas is not mixed immediately upstream of the bubble dispersion mechanism. The subscript t represents the state of the liquid that has become a two-phase flow after gas mixing on the downstream side immediately downstream of the bubble dispersion mechanism, and the subscript a represents the state of the gas.
In particular, Pa is the gas mixing pressure excluding the pressure loss passing through the bubble dispersion mechanism. When gas is mixed, fine single bubbles are generated and dispersed and mixed in a large amount in the liquid.The momentum of the gas can be transmitted to the liquid, and the momentum of the liquid can be surely increased. Simultaneously, the bubble velocity becomes almost the same as the liquid velocity immediately after the bubbles are mixed, so that the pressure momentum of the gas can be transmitted to the liquid very efficiently, and it functions as a bubble pump. If the bubble diameter is small, the rigidity is high. Therefore, unnecessary deformation and vibration do not occur in the liquid, so that energy loss due to bubbles in the liquid is small. If the gas mixing ratio exceeds approximately 4, the function as a bubble pump is reduced since the bubble flow changes to an annular flow or a spray flow. Therefore, it is desirable to set the gas mixing ratio to 4 or less as an operating condition.

ある。When a liquid pump or the like is used, the size of the pump can be reduced for exactly the same reason. Furthermore, in order to connect the liquid pump to the liquid path pipe for normal pump-up, the liquid pump must be connected between the liquid path pipe and the liquid pump to prevent the backflow of dirty liquid due to the operation of the liquid pump affecting the liquid path pressure. Although it is necessary to provide a liquid storage tank that is open to the atmosphere, the operation principle of the bubble pump in the present invention is completely different from that of the conventional liquid pump. It is possible to directly connect to the road piping, so that the entire apparatus can be greatly simplified. It should be noted that the working fluid pressure can be lowered
It goes without saying that the pressure required for gas mixing can be lowered at the same time.

能にしておくことが好ましい。In the present invention, the bubble diameter can be controlled by controlling the shearing force between the liquid and the gas, that is, the liquid velocity, the opening area of the bubble dispersion mechanism, and the residence time after bubble generation. . By controlling the bubble diameter in this way, it is possible to control the cleaning power. In the portion to be cleaned, in the liquid containing bubbles, bubbles having a small density and a small kinetic energy and a liquid between bubbles having a large density and a large kinetic energy alternately collide with the portion to be cleaned in a short cycle. As a result, pressure fluctuation, that is, vibration occurs in the portion to be cleaned. Since the frequency of this vibration can be controlled by changing the number of bubbles colliding per unit time, it is possible to generate ultrasonic vibration having particularly high detergency. Since ultrasonic vibration has a short wavelength, if it collides with a solid surface etc. after ejection, it can act even into fine irregularities on the solid surface, so the cleaning power when used for cleaning is extremely high It is very suitable when used for a chemical reaction or heat exchange because the reaction boundary layer and the temperature boundary layer can be thinned and the diffusion rate in the boundary layer can be improved. The effect of the vibration frequency on these effects is that the higher the vibration frequency, the shorter the wavelength.Thus, it works even in the fine irregularities on the surface, but the vibration is quickly attenuated and the working area becomes smaller, and the lower the vibration frequency, the longer the wavelength. Therefore, the local acting force is reduced, but the vibration is attenuated slowly and the acting area is widened. Controlling is possible by changing the vibration frequency in this way, but if the bubble diameter is controlled with the same amount of gas, the number of bubbles per unit time will be different, and the frequency of the vibration generated when colliding will be changed. Can be. That is, by controlling the bubble diameter, it is possible to control the range and strength of the action. Further, when the present invention is used for a liquid containing a large amount of scale or the like, an independent opening present on the surface of the bubble dispersing mechanism may be closed by a compound of a scale component such as calcium carbonate. Alternatively, even when a chemical reaction that precipitates a solid component occurs, the blockage may occur similarly. If the opening is closed, the pressure at the time of gas mixing increases, which may cause problems such as a decrease in gas flow rate, which is not preferable.
Since such a compound of the hardness component can be easily dissolved under acidic conditions, when the closed portion is washed with an acidic liquid solution, the compound of the hardness component falls off and an initial state can be obtained. When used under operating conditions in which blockage is unavoidable, it is preferable to make the bubble dispersion mechanism detachable so that maintenance and maintenance such as replacement and cleaning can be performed when the hole is blocked.

ンプとしての総合効率が低下する。There is also a method of mechanically crushing after mixing to promote the transfer of momentum from the gas to the liquid. However, this method involves changing the pipe shape to generate turbulence in the flow or mixing the mixed phase after mixing. A gas mass is crushed by using a shear force by passing a flow through a mesh or the like. In this case, since the energy loss of the flow itself is large, the liquid pressure required for operation and the energy to be applied are very large. At the same time, the phase is easily changed to the spray flow, and the overall efficiency of the pump is reduced.

On the other hand, the gas flowing from the gas inlet 23 is pressurized by the gas pressurizing means 22 using a compressor or the like, and dispersed and mixed as fine bubbles in the flowing liquid by the gas mixing and mixing device 1. The fine bubble flow 21 containing a large amount of fine bubbles generated by the gas mixing and mixing device 1 is discharged to the storage tank 26. Here, air contains a small amount of ozone as a gas, and water is used as a liquid. Since ozone has a sterilizing and bleaching action, using ozone water 20 containing ozone,
It can be used for various sterilization, bleaching and storage. In the gas mixing and mixing device 1, since a large amount of fine bubbles are dispersed and mixed in the flowing liquid, momentum is reliably transmitted, and the device functions as a bubble pump device. For this reason, a gas absorbing unit that consumes very little driving energy by the liquid pressurizing unit 24 and the gas pressurizing unit 22 that provide a driving force necessary for driving the apparatus is obtained. Further, the gas can be directly supplied from a pressure source such as a cylinder or a pressure tank without using the gas pressurizing means 22, and the pressure can be supplied without using the liquid pressurizing means 24 especially when supplying the liquid. Can be supplied directly from the source. Since the fine bubble flow 21 contains a large amount of fine bubbles, both phases are not immediately separated due to a difference in density of gas and liquid, and the jet distance of the fine bubble flow 21 can be extremely large. Therefore, it is suitable as an application for stirring the storage phase 26, and the absorption time can be greatly improved because the time for maintaining the fine bubble flow is very long and the gas-liquid contact area is very large. Here, the present invention is used as the gas absorbing means, but it is also possible to degas the gas component contained in the liquid, and when the gas and the liquid cause a chemical reaction, the present invention is used as a field of the chemical reaction. Needless to say, it is also possible to apply The liquid 20 stored in the storage phase 26 is collected by a pump or the like (not shown) as necessary.

広範囲を効率よく処理可能であり好適である。When the microbubble flow 21 collides with the solid surface, it generates a vibration having a frequency defined by the number of bubbles per unit time. Since the fine bubble flow contains a large amount of fine bubbles, its vibration frequency is very high and reaches the ultrasonic range. When such high-frequency vibrations occur on the solid surface, the collision stress acts on the minute irregularities on the solid surface, so that the cleaning effect is excellent, and the boundary layer can be made extremely thin, promoting heat transfer and chemical reactions. I do. So the storage phase 26
Can also be used as a washing tank or a reaction layer. In this case, a solid (not shown) to be treated is put in the storage tank 26 and the microbubble flow 21 is caused to directly collide with the surface of the solid. In particular, it is preferable to generate a plurality of microbubble flows using a plurality of bubble-mixing / mixing devices and simultaneously impinge them on the solid surface, since a wide range can be efficiently treated.

The liquid flowing from the liquid inlet 27 of the bubble pump device 38 is pressurized by the liquid pressurizing means 28 and sent to the gas mixing and mixing device 1 shown in FIG. On the other hand, the gas flowing from the gas inlet 36 is pressurized by the gas pressurizing means 35 and is finely dispersed and mixed in the flowing liquid in the gas mixing and mixing device 1. Microbubble flow 31 generated by gas mixing and mixing device 1
Is immediately discharged into the atmosphere from the discharge port 30. Storage tank 3
4, a solid sample 33 is set on a fixed table 32,
The structure is such that the microbubble flow 31 collides. Since the fine bubble flow 31 is a bubble flow containing a large amount of fine bubbles,
Unlike the spray, slag, and annular flows, it does not generate unnecessary vibration, noise, or droplets when discharged from the discharge port. Also, when colliding with the solid sample 33, a large amount of microbubbles are included, so that the liquid is not easily scattered and the liquid is very easily collected, so that the collision speed can be greatly improved as compared with the case of using only the liquid. In addition, in order to generate high-frequency vibrations such as ultrasonic waves at the time of collision, the processing speed can be greatly improved when performing chemical reaction, heat transfer, and cleaning, and the used liquid can be easily collected. No vibration or noise occurs. Here, a cleaning device for cleaning the surface of the solid sample 33 is shown, in which water is used by dissolving a trace amount of a surfactant in an organic solvent such as alcohol, acetone and methyl ethyl ketone. In addition to these cleaning uses, the present invention is also suitable for use in chemical reactions such as etching and oxidation of semiconductors and heat transfer such as melting of frozen solids. Liquid to control the processing speed,
The temperature of the gas or solid may be controlled, and the temperature of the atmosphere or the oxidizing or reducing atmosphere may be changed. If the bubble mixing and mixing device 1 can be removed, a bubble dispersing mechanism having a different pore diameter can be used depending on the application in order to control the vibration frequency at the time of collision, and it is possible to perform cleaning when pores are clogged. This is desirable because maintenance can be easily performed. In addition, since the bubble diameter can be controlled by changing the residence time after bubble generation, the distance between the gas mixing and mixing device 1 and the discharge port 30 may be changed, and the internal flow velocity, the flow path cross-sectional area, and the liquid flow rate may be changed. You may change it. In these cases, it is possible to control the bubble diameter in a wide range by making the pipe downstream from the gas mixing and mixing apparatus 1 replaceable.
