Description

Cloud water collection device and cloud water collection method

Technical Field

The invention relates to the field of cloud water collection, in particular to a cloud water collection device and a cloud water collection method.

Background

Cloud is generally a complex system consisting of atmosphere, cloud nuclei (or "aerosols"), liquid or solid water. Cloud is usually high in mountainous regions. Through the research on the particle size distribution and chemical components of the cloud water, scientific support can be provided for the research on the atmospheric environment and artificial influence weather. In order to study the particle size distribution, chemical components and change rules of the cloud water, a cloud water sample is usually required to be collected. Single-stage or multi-stage mist and water samplers have been developed. The cloud and mist water sampler generally achieves the purpose of collecting a cloud and mist water sample by intercepting mist drops by using a Teflon rope or a Teflon rod, wherein Teflon refers to polytetrafluoroethylene (Teflon for short).

Chinese patent No. CN101769831B discloses a mist and water collecting device. The fog collecting device is provided with a hollow shell. The housing has an inlet and an outlet, and a rain cover is disposed over the inlet. Both the mist-water absorbing net and the blower are disposed in the housing, and the blower is located downstream of the mist-water absorbing net. A mist collecting vessel is arranged at the lower end of the mist absorbing net and is used for collecting condensed mist. Another cloud water collector is disclosed in US4,697,462. The cloud water collector has a housing divided into a front portion and a rear portion. Three teflon rope nets are arranged in the front housing, a fan is arranged in the rear housing, and a rain-proof device may be installed at the inlet of the front housing. And a cloud and mist water drop collecting device is arranged below the Teflon rope net.

However, in the above two schemes of the mist water collecting device, the influence of the fan speed on the collecting function is not mentioned. In fact, the speed of the fan is closely related to the collection function of the mist collection device. Different fan suction speeds will determine the mist water with different particle diameters and wide collected by the mist water collecting device. The faster the rotation speed of the fan, the stronger the suction force provided by the fan, the wider the mist particle diameter section which can collide and condense on the mist absorbing net, so that the particle diameter of the mist particles which can be collected is finer. In other words, the collection function of the cloud and mist water collection device in the prior art is insufficient. Moreover, the prior art cloud water collection device is not modularized, resulting in further limited functionality.

Accordingly, there is a need in the art for a new solution to the above-mentioned problems.

The invention provides a cloud and mist water collecting device 3, which aims to solve the technical problems that an existing cloud and mist water collecting device is insufficient in collecting function and has no modularization. The cloud and mist water collection device 3 comprises: at least one cloud water collector 1, 1a; and a controller 31, the controller 31 being configured to control at least one cloud water collector 1, 1a, wherein each cloud water collector 1, 1a comprises: a housing 11, the housing 11 having an inlet 111a, an outlet 111b, and a hollow chamber between the inlet 111a and the outlet 111b along a longitudinal direction thereof; at least one cloud water collection screen 12, each cloud water collection screen 12 being positionable in the hollow chamber 14 and having its upper end 12b inclined toward the inlet 111a such that the windward side 12a of each cloud water collection screen 12 forms an acute included angle θ with the longitudinal centerline C of the hollow chamber 114; and a fan 15, the fan 15 being positioned downstream of the cloud water collection network 12 and proximate to the outlet 111a of the housing 11, the fan 15 being variable speed.

Reference herein to a "longitudinal centerline C" refers to the centerline of the housing of the cloud water collector that is parallel to the flow direction of the cloud water from the inlet to the outlet within the housing, e.g., based on the orientation shown in fig. 1, with the longitudinal centerline C coinciding with the horizontal direction. The inlet of the housing refers to the inlet of the mist-water stream into the housing, and the outlet refers to the outlet of the mist-water stream out of the housing.

Fig. 1 is a schematic view of a first embodiment of a cloud water collection device of the present invention. As shown in fig. 1, in one or more embodiments, the cloud water collection device 3 includes a controller 31 and a cloud water collector: a first cloud water collector 32. The controller 31 is configured to control the first cloud water collector 32, including but not limited to controlling a fan and/or an electrical heating device of the first cloud water collector 32. The controller 31 can be any suitable control device known in the art including, but not limited to, a field controller and a remote controller, such as a push button controller, a touch screen controller, a programmable controller, and the like. The first cloud water collector 32 is constituted by the cloud water collector 1 or 1 a.

Fig. 2 is a schematic cross-sectional view of a first embodiment of a cloud water collector in the cloud water collection device of the present invention, and fig. 3 is a right side view of the first embodiment of the cloud water collector in the cloud water collection device shown in fig. 2. The schematic cross-sectional view of fig. 2 is taken along the longitudinal centerline C of the cloud water collector 1. As shown in fig. 2 and 3, in one or more embodiments, the cloud water collector 1 includes a housing 11, three cloud water collection screens 12, a condensation cloud water storage device 13, a rain-proof cover 14, and a fan 15. The condensation cloud storage 13 can be interchangeably placed under the cloud collection screen 12.

As shown in fig. 2, in one or more embodiments, the housing 11 includes a housing body 111 and a housing blower portion 115 integrally connected to the housing body 111. Along the direction of the longitudinal centerline C, one longitudinal end of the housing main body 111 forms an inlet 111a, and the other opposite longitudinal end of the housing main body 111 abuts against one longitudinal end of the housing fan section 115. The other opposite longitudinal end of the housing blower portion 115 forms an outlet 111b. The housing blower portion 115 is configured to receive the blower 15 therein. A hollow chamber 114 extending from the inlet 111a to the outlet 111b is formed in the housing main body 111 and the housing blower portion 115. The housing 11 is preferably made of plexiglas, which material does not contaminate the sample to be collected. Alternatively, the housing 11 may be made of other suitable inert resins.

In one or more embodiments, the housing 11 is formed as a generally rectangular parallelepiped box having a square cross-section (which is perpendicular to the longitudinal centerline C). Wherein the square cross section of the housing body 111 is smaller than the square cross section of the housing blower portion 115. In other words, the housing blower portion 115 expands radially outwardly relative to the housing body 111 to accommodate the blower 15. Alternatively, the housing 11 may take the shape of a rectangle or other suitable cross-sectional shape. A plurality of first connection means 21 are also provided on the outer wall of the inlet end of the housing 11. These first connecting means 21 are provided so as to be detachably connected with connecting means provided at corresponding positions of the rain-proof cover 14 to fix the rain-proof cover 14 to the inlet 111a of the housing 11. The first connection means 21 are provided as, for example, connection flanges protruding radially outwards from the housing 11 around the inlet 111a, which can be fastened together with connection means on the rain-proof cover 14 by means of bolts or screws. Alternatively, the first connecting means 21 may also be configured as a suitable snap or snap-hole structure. Preferably, a sealing structure may be provided at the junction between the housing 11 and the rain-proof cover 14 to ensure that air flow or rain does not penetrate into the housing 11 from the junction. A plurality of second connection means 22 are also provided on the outer wall of the end portion where the housing main body 111 and the housing fan section 115 are abutted against each other. These second connection means 22 are provided to fix the housing main body 111 and the housing blower portion 115 together. The second connection means 22 are provided as connection flanges protruding radially outwards around the housing body 111, which may be fastened together by means of bolts or screws. Alternatively, the second connection means 22 may also be configured as a suitable snap or snap-hole structure or other suitable connection structure. A sealing structure may also be provided at the junction between the housing body 111 and the housing blower portion 115 to ensure that air flow or rain water does not penetrate into the housing 11 from the junction. Alternatively, the rain-interference preventing cover 14 may be integrally formed with the housing 11; the housing main body 111 and the housing fan section 115 may be integrally formed.

In one or more embodiments, as shown in fig. 2, three slots (not shown) are provided in the housing body 111, and one cloud water collection network 12 may be inserted into each slot. The slots are spaced a predetermined distance from each other and are parallel to each other. The distance between each slot and the inlet 111a is smaller than the distance between the corresponding slot and the outlet 111 b. In other words, the slot is positioned adjacent to the inlet 111a. Each slot extends between a top wall 111C and a bottom wall 111d of the housing body 111, and an upper end of each slot is inclined toward the inlet 111a of the housing 11 such that the slot forms an acute angle θ with the longitudinal center line C. The upper end 12b (see fig. 3) of the cloud water collection screen 12 inserted into the slot is thus also inclined towards the inlet 111a, and the windward side 12a of the cloud water collection screen 12 also forms an acute angle θ with the longitudinal center line C of the housing 11. Since the bottom wall 111d of the housing main body 111 is parallel to the longitudinal center line C, the windward side 12a of the cloud water collecting net 12 and the bottom wall 111d of the housing main body 111 also form an acute angle θ. Preferably, the acute included angle θ is set to 55 °, and at this included angle, the condensation efficiency of the mist and water can be optimized. Alternatively, the acute included angle θ may be an angle less than 55 ° or greater than 55 °, such as 60 ° or other suitable angle. This angular arrangement facilitates the rapid flow of the condensed cloud water to the lower end of the cloud water collection screen 12. Alternatively, fewer than three slots, for example one or two, may be provided on the housing body 111. Accordingly, the number of cloud water collection screens 12 is also less than three, such as one or two corresponding to the number of slots. Alternatively, the cloud water collection network 12 may be inserted into only a portion of the slots, depending on the actual viewing needs. It should be noted that the number of cloud water collection screens is related to the collection efficiency. The more the number of cloud and mist water collecting nets is, the higher the collecting efficiency is, but the wind resistance is increased.

As shown in fig. 2, in one or more embodiments, a slot cover 112 is also provided on the top wall 111c of the housing main body 111 to be rotatably opened and closed. The slot cover 112 may sealingly cover the upper inlets of all slots to prevent rainwater or other foreign matter from entering the housing body 111. Alternatively, slot cover 112 may take other suitable configurations, such as a sliding configuration. As shown in fig. 1, in one or more embodiments, a condensation cloud sink 113 is provided on the bottom wall 111d of the housing body 111. The condensed mist water tank 113 is disposed below the lower end 12c (see fig. 3) of the mist water collecting net 12 to collect condensed mist water drops that drop or flow down from the mist water collecting net 12. The bottom of the condensation mist reservoir 113 is provided with a hole structure (not shown in the figures) for discharging condensation mist water, and the hole structure is configured to be in fluid communication with the condensation mist water storage means 13. The condensation cloud storage device 13 may be in a suitable form such as a storage bottle or a storage tank.

In one or more embodiments, the condensation cloud sink 113 is made of a teflon (i.e., polytetrafluoroethylene) material such that the condensation cloud sink 113 has high temperature resistant properties. Alternatively, the condensation mist reservoir 113 may be made of other suitable inert resin materials. In one or more embodiments, an electrical heating device is provided below the bottom of the condensation cloud water trough 113 to heat the condensation cloud water trough 113 in the event that the ambient temperature is relatively low (e.g., winter) which may cause the condensation cloud water trough 113 to freeze, thereby ensuring that the cloud water collection is not affected by icing conditions. The electrical heating means may take forms including, but not limited to, electrical heat tracing strips or silica gel heating plates. The electric tracing band is usually composed of a conductive polymer and two parallel metal wires and an insulating sheath. The electric tracing band not only can automatically adjust output power, but also can automatically limit heating temperature. The silica gel heating plate is a flexible thin sheet-like heating element, and is generally composed of two sheets formed by sandwiching silica gel between upper and lower sheets made of glass fiber cloth and compacting the silica gel. Due to the softness of the silica gel heating plate, it can form close contact with the bottom of the condensed mist water tank 113, contributing to improved heat transfer. In the actual operation of the cloud and mist water collector, in the case where the heating wire 123 is provided in the condensation string 122, the heating of the condensation cloud and mist water tank 113 may be performed in synchronization with the heating of the condensation string 122.

In one or more embodiments, the rain-interference cover 14 is removably attached to the inlet end of the housing 11. In one or more embodiments, as shown in fig. 2, the cross-section of the rain-interference cover 14 along the direction of the longitudinal centerline C is generally triangular. Alternatively, the rain-proof cover 14 may be designed as a hollow structure of other shapes, such as a square or rectangular parallelepiped structure with an opening at the bottom. The rain-proof cover 14 is surrounded by straight walls, so that the processing is easier, and the cost can be saved. Based on the orientation shown in fig. 2, the rain-interference cover is a hollow structure surrounded by a top side 14a, a bottom side 14b, a right side 14c, a front side 14d, and a rear side (which is opposite the front side 14d and is not visible in the drawing). The bottom side 14b may be entirely open, forming a cloud water vapor inflow 141. An opening is also formed on the right side 14c to interface with the inlet 111a of the housing 11, so that a flow passage from the mist and water vapor inflow port 141 to the right opening is formed in the rain-proof water interference cover 14. The remaining top side 14a, front side 14d and rear side are each constructed of straight walls. The top side 14a extends obliquely from the top edge of the right side 14c to the left and downward side of the bottom side 14b, thus forming an angle a with the bottom side 14 b. The angle a may be, for example, 35 ° or 40 ° or 60 ° or another suitable acute angle. By providing a suitable acute included angle, the top side 14a can help direct the flow of mist and water to the mist and water collection network 12. The cloud water enters the rain-proof cover 14 in direction a and forms a cloud water flow B shown in fig. 2 along the flow path within the rain-proof cover 14. Alternatively, the cloud water collector 1 may be configured without a rainwater interference preventing cover according to actual needs.

As shown in fig. 3, the blower 15 is disposed within the housing blower portion 115. In one or more embodiments, the blower 15 is removably mounted within the housing blower portion 115 such that the blower 15 is replaceable. The blower 15 is variable speed, for example, providing different speeds of 8 m/s and 2 m/s. In one or more embodiments, the blower 15 is a variable frequency blower, such as a variable frequency blower that includes a speed governor. Alternatively, the blower 15 may take the form of another suitable variable speed blower. In one or more embodiments, a cloud water collector 1 may be provided with a fan 15. Alternatively, one cloud water collector 1 may be provided with more than one fan 15, each fan 15 having a different wind speed configuration for replacement when required, so as to be able to meet different observation needs.

Fig. 5 is a schematic cross-sectional view of an embodiment of a coalescing rope of a cloud water collection network in a cloud water collection device of the present invention. In one or more embodiments, as shown in fig. 5, the coagulation ropes 122 are hollow in structure, thus forming a hollow lumen 122a within each coagulation rope 122. A heating wire 123 may be disposed within the inner cavity 122a. The heating wire 123 may be electrically connected to an external power source through an electrical connection device. The electrical connection means may be arranged at a position on the housing 11 corresponding to the cloud water collection network 12 or directly on the cloud water collection network 12. For example, a power interface is provided at the lower end 12c of each cloud water collection network 12. The heating wire 123 is controlled to heat the condensation rope 122, so that the cloud and fog water collecting device can work normally even in seasons (such as winter) when frost fog occurs, and the functions of the cloud and fog water collecting device are further expanded.

Fig. 6 is a schematic cross-sectional view of a second embodiment of a cloud water collector in a cloud water collection device of the present invention. As shown in fig. 6, an alternative cloud water collector 1a is provided. In this embodiment, the air distribution plate 16 is provided in the housing 11, so that the cloud water air flow distribution in the cloud water collector 1a can be more uniform. The air distribution plate 16 is configured to cover the entire cross-section of the hollow chamber 14 perpendicular to the longitudinal centerline C. The air distribution plate 16 is arranged between the cloud water collection net 12 and the fan 15. Optionally, the distance between the air distribution plate 16 and the fan 15 is shorter than the distance between the air distribution plate and the cloud water collection screen 12. The air distribution plate 16 is spaced apart from the blower 15 by a second predetermined distance L2. In one or more embodiments, the second predetermined distance L2 between the air distribution plate 16 and the blower 15 is set to 5 cm, which may provide a more uniform distribution of the air flow. Alternatively, the second predetermined distance L2 may also take a size other than 5 cm, depending on the actual size of the cloud water collector. Uniformly distributed vents (not shown) are provided in the air distribution plate 16 to allow the flow of mist and water over the air distribution plate 16. In one or more embodiments, the air distribution plate 16 is provided with uniformly distributed honeycomb-shaped hexagonal openings (not shown).

Fig. 7 is a schematic view of an installation scheme of the first embodiment of the cloud water collection device of the present invention shown in fig. 1. The cloud and water collecting device 3 of the present invention can be installed in a mountain area. As shown in fig. 7, the first cloud water collector 32 of the cloud water collecting apparatus 3 is installed on top of the mountain 4 having the first height gradient H1. The speed of the fan 15 of the first cloud water collector 32 is controlled by the controller 31, and the first cloud water collector 32 can collect cloud water samples with different particle sizes.

In the case where the diameter of the coagulation rope 122 made of teflon material is 0.5 mm and the interval between the adjacent coagulation ropes 122 is 2 mm, when the wind speed of the blower 15 is set to 8 m/s, if the collection efficiency is 60%, the minimum mist particle diameter that can be collected is about 5 μm. Under other conditions, when the wind speed of the fan 5 is set to 2 m/s, the minimum diameter of the mist particles that can be collected is about 11 μm.

When the electric heating wire 123 is arranged in the condensation rope 122 of the cloud water collecting net 12 of the first cloud water collector 32, the controller 31 can also control the power on and power off of the electric heating wire 123. For example, during winter season, when it is desired to collect frost mist in the area where the mountain 4 is located, the controller 31 is configured to control the first cloud water collector 32 to perform the heat-suction collection mode. The heating-sucking collection mode can prevent the ice melting process from evaporating too fast and prevent the fan from sucking and discharging collected fog particles. In the heat-suction collection mode, the controller 31 turns on the fan 15 of the first cloud water collector 32 for a first predetermined period of time, such as 20 minutes or other suitable period of time; after a first predetermined period of time has elapsed, the fan 15 is turned off and the heating wire 123 is energized to heat the cloud water collection network 12 for a second predetermined period of time, for example, 5 minutes or other suitable period of time, the ice on the cloud water collection network 12 being heated to melt and then allowed to drip into the condensation cloud water storage device 13; after a second predetermined period of time, the heating wire 123 is powered off, and the steps of turning on the blower 15 and continuing to run for the first predetermined period of time are repeated, so that the cycle is repeated until the collection task is completed.

Fig. 8 is a schematic view of a second embodiment of the cloud water collection device of the present invention. As shown in fig. 8, in one or more embodiments, the cloud water collection device 3 of the present invention includes a first cloud water collector 32, a second cloud water collector 33, and a controller 31 that controls the first cloud water collector 32 and the second cloud water collector 33. The first cloud water collector 32 and the second cloud water collector 33 may share the same controller 31, or may be provided with separate controllers 31, respectively. The first cloud water collector 32 and the second cloud water collector 33 are each constituted by either one of the cloud water collectors 1 or 1a described above. Each cloud water collector forms a module. The configuration of the first cloud water collector 32 may be the same as or different from the configuration of the second cloud water collector 33, depending on the requirements of the observation scheme. When the cloud water collecting device provided by the invention is provided with a plurality of cloud water collectors, the cloud water collectors can be transported and installed separately. Because the volume of a single cloud and mist water collector module is smaller, the cloud and mist water collector device is convenient to transport and install and is particularly suitable for mountain areas. In alternative embodiments, the cloud water collection device of the present invention may have more than two cloud water collectors, and the configuration of the cloud water collectors may be the same or different, as required by the actual observation scheme.

Fig. 9 is a schematic view of a first installation scheme of a second embodiment of the cloud water collection device of the present invention shown in fig. 8. As shown in fig. 9, a first cloud water collector 32 of the cloud water collecting apparatus of the present invention is installed on top of a mountain 4 having a first height gradient H1, and a second cloud water collector 33 is installed at a position of the same mountain 4 having a second height gradient H2. The second height gradient H2 is lower than the first height gradient H1, for example half or less of the first height gradient H1. By means of the installation scheme, the cloud and mist water collecting device 3 can implement different height gradient cloud and mist water collecting modes. In the different-height-gradient cloud water collection mode, when collecting cloud water samples of different height gradients in the mountain, the fans 15 of the first and second

cloud water collectors

32 and 33 are operated simultaneously at the same speed so as to collect cloud water samples from different height gradients simultaneously.

Fig. 10 is a second installation plan view of the second embodiment of the cloud water collection device of the present invention shown in fig. 8. As shown in fig. 10, the first and second mist and

water collectors

32 and 33 of the mist and water collecting device of the present invention are installed at the same position, that is, on top of the mountain 4 having the first height gradient H1. Through the installation scheme, the cloud and fog water collection device can implement a classified cloud and fog water collection mode. In the classified mist-water collection mode, the fans 15 of the first mist-water collector 32 and the second mist-water collector 33 are operated simultaneously, but the fan speed of the first mist-water collector 32 is different from the fan speed of the second mist-water collector 33. In other words, two cloud and mist water collectors with different wind speeds collect mist water at the same place in a mountain area. For example, the fan speed of the first cloud water collector 32 is 8 m/s, and the fan speed of the second cloud water collector 33 is 2 m/s. In this case, the first cloud water collector 32 may collect the cloud water sample a having a particle size of >5 μm, and the second cloud water collector 33 may collect the cloud water sample B having a particle size of >11 μm. Then, when the cloud and mist water sample results are analyzed, the chemical components of the two cloud and mist water samples A and B are respectively analyzed to obtain the difference between the two; the difference between the cloud water samples A and B is then used to represent the cloud water characteristics of the 5-11 μm particle size segment, while the results of the cloud water sample B directly represent the cloud water characteristics of the particle size segment with a particle size >11 μm. Therefore, the cloud and water classification (different particle size sections) sampling target can be realized through the cloud and water samples A and B.

In summary, the cloud and mist water collection device 3 of the invention can respectively achieve the purpose of collecting cloud and mist water at different heights in mountains or in a single station by selecting the combination of the cloud and mist water collectors with different rotation speeds at a single position and selecting the combination of the cloud and mist water collectors with the same rotation speed at a plurality of different height positions, thereby expanding the use scene of the cloud and mist water collection device and reducing the mist water collection cost and the maintenance difficulty.

Fig. 11 is a flow chart of a cloud water collection method of the cloud water collection device of the present invention. As shown in fig. 11, the cloud water collection method according to any one of the above-described cloud water collection devices includes steps S1, S2, and S3. In step S1, a target cloud water particle size to be collected is determined. For example, the cloud water particle size required to be collected in a predetermined observation scheme is 5 μm or 11 μm, or the cloud water particle size section of 5 to 11 μm and the cloud water particle size section of >11 μm are required to be collected separately in a hierarchical collection mode. In step S2, the speed of the fan is selected based on the target cloud water particle size. For example, when the target cloud water particle size is 5 μm, the speed of the blower may be selected to be 8 m/s. When the target cloud water particle size is 11 μm, the speed of the blower can be selected to be 2 m/s. In step S3, a fan is turned on to draw a stream of cloud water from the atmosphere through a network of condensation ropes at a selected rate to collect a target cloud water sample. Therefore, in the cloud and mist water collection method, cloud and mist water samples with different particle diameters can be collected by utilizing different speeds of the fan.

Further, the cloud and mist water collecting method of the present invention may further include a heating-suction cloud and mist water collecting method, a different-height gradient cloud and mist water collecting method, and a classified cloud and mist water collecting method. In one or more embodiments, in the heating-suction cloud water collection method, the heating wire 123 needs to be disposed in the inner cavity of the condensation string of the cloud water collection net. In the heating-pumping cloud water collection method in the presence of the frost fog, the step S3 further includes the following steps: the blower 15 is turned on for a first period of time, such as 20 minutes or other suitable period of time; after a first period of time, the blower 15 is turned off, and the heating wire 123 is energized for a second period of time, such as 5 minutes or other suitable time; after the second period of time, the heating wire 123 is powered off, and the steps of turning on the blower 15 and continuing for the first period of time are repeated. In one or more embodiments, to implement the hierarchical cloud water collection method, the cloud water collection device 3 includes a first cloud water collector 32 and a second cloud water collector 33, and the first cloud water collector 32 and the second cloud water collector 33 are disposed at the same location. In the classified cloud and mist water collection method, the step S3 further comprises the following steps: the fan 15 of the first cloud water collector 32 is controlled to operate at a first speed (e.g., 8 meters/second) while the fan 15 of the second cloud water collector 33 is controlled to operate at a second speed (e.g., 2 meters/second) different from the first speed in order to collect the cloud water samples in stages. In one or more embodiments, to implement different height gradient cloud water collection methods, the cloud water collection device 3 includes a first cloud water collector 32 and a second cloud water collector 33, the first cloud water collector 32 being disposed at a first predetermined location having a first height gradient H1, the second cloud water collector 33 being disposed at a second predetermined location having a second height gradient H2, wherein the second height gradient H2 is lower than the first height gradient H1. In the method for collecting the cloud and mist water with different heights, the step S3 further comprises the following steps: the fans 15 of the first and second

cloud water collectors

32, 33 are simultaneously controlled to operate at the same speed (e.g., 8 m/s or 2 m/s) so as to collect cloud water samples from different height gradients.
