Description

  The present invention relates to a net-type deodorization apparatus used for odor countermeasures such as an open type barn or a compost house.

  Conventionally, a net-type deodorizing device that drops a deodorizing liquid on a net that is spread at the opening of such a foul odor generating facility is known as a device that suppresses the spread of foul odors from open livestock barns, compost houses, food factories, etc. ing.

  For example, Patent Document 1 discloses that a mesh-like liquid that is spread at the opening of a foul-odor generating facility, an upper bottle that is disposed above the mesh-like liquid, and a lower bottle that is disposed below the mesh-like liquid. And a deodorizing apparatus that drops a deodorizing liquid from an upper tub and flows down along a mesh-like liquid.

  In the deodorizing apparatus of the same document, a deodorizing liquid flow lower part made up of a large number of through holes is formed in the upper bottle, and the deodorizing liquid in the upper bottle is dropped from the deodorizing liquid flow lower part. Further, in the same document, as the deodorizing liquid flow lower part, a fiber body in which one end is immersed in the upper tub and the other end is drooped outside beyond the upper edge of the upper tub is provided by capillary action. A configuration for flowing down the deodorant liquid is disclosed.

  Further, for example, in Patent Document 2, a material having a certain length range is thickly formed from the upper edge of the deodorizing net immersed in the deodorizing liquid, or a woven fabric having a high capillary phenomenon is attached to the portion. For example, it is described that the capillary phenomenon of the part is activated.

  However, the above-described prior art has room for improvement in terms of maintaining a good wet state of the entire net by uniformly flowing a sufficient amount of deodorant liquid.

  That is, in the prior art, there is a problem that the amount of deodorant flowing down is small and does not flow uniformly, so that a region not wetted by the deodorant remains in the lower part of the net and the deodorizing effect is reduced. . In particular, since the net spread in a barn or the like has a relatively large size (for example, a horizontal width or height of 2 to 5 m or more), it is difficult to uniformly wet the entire net.

  Specifically, as in the conventional technique disclosed in Patent Document 1, in the method in which the deodorant liquid flows down from a large number of through holes formed in the upper ridge, if the through holes are enlarged in order to increase the flow amount, Under the influence of the flow of the deodorizing liquid supplied to the upper soot, the amount of the deodorizing liquid dropped from each through hole becomes non-uniform. Moreover, when there is much flow-down amount of a deodorizing liquid, the deodorizing liquid dripped from a through-hole will collide with a net | network and will be scattered around.

Moreover, it is difficult to increase the flow amount of the deodorant liquid by a method in which one end of the net is immersed in the upper basket and the deodorant liquid is caused to flow down by utilizing a capillary phenomenon. Even if the capillary phenomenon is activated by thickly configuring the vicinity of the upper end of the net as in the prior art disclosed in Patent Document 2, there is a limit to the increase in the amount of flow.
There is also a problem in that dust or the like entering the upper ridge adheres to and accumulates on the net, thereby preventing the capillary phenomenon and preventing the uniform flow of the deodorant liquid.

  The present invention has been made in view of the above circumstances, and the object of the present invention is to uniformly flow a liquid such as a deodorizing liquid and to increase the flow amount of the liquid to enhance the deodorizing effect and the like. An object of the present invention is to provide a net-type deodorizing device that can be used.

  The net-type deodorization apparatus of the present invention collects a watering container capable of storing a liquid to flow down, a net suspended from the watering container to flow the liquid, and disposed below the net to collect the liquid. A drainage hole that extends in a horizontal width direction of the net and allows the liquid to flow out, and is formed inside the watering container. A support having a shape that cannot pass through the outflow hole is disposed, and the vicinity of the upper end side of the net is inserted into the outflow hole and connected to the support.

  According to the net-type deodorizing apparatus of the present invention, a slit-like outflow hole that extends in the horizontal width direction of the net and allows the liquid to flow out is provided at the bottom of the watering container in which liquid such as deodorant liquid is stored. Is formed. As a result, liquid such as deodorant liquid can flow down from the outflow hole using gravity, so that a larger amount of liquid compared to the conventional technique of sucking down the deodorant liquid using capillary action and then flowing down. Can flow down efficiently. As a result, the entire net can be moistened substantially uniformly, the amount of liquid flowing down can be increased, and the deodorizing effect and the like can be enhanced.

  Further, the vicinity of the upper end side of the net is inserted into the outflow hole and connected to a support body disposed inside the water spray container, so that the liquid in the water spray container flows out from the outflow hole along the net. Therefore, it is possible to increase the flow amount while suppressing the scattering of the liquid.

  Moreover, since a support body is a shape which cannot pass an outflow hole, the net connected to the support body inside the water spray container can be supported by the bottom part of the water spray container. As a result, a suitable stretched state of the net can be maintained.

  Further, in the vicinity of the upper end side of the net, a substantially cylindrical or substantially bag-like support insertion portion extending along the upper end side is formed, and the support is substantially rod-shaped or thicker than the opening width of the outflow hole. It may be substantially tubular and may be inserted through the support insertion portion. Thereby, the vicinity of the upper end side of the net can be stably supported over the entire width in the horizontal direction, and the net can be suitably stretched while suppressing slack. Moreover, the connection work of a net | network and a support body can also be performed easily.

  Moreover, the convex part which protrudes by predetermined | prescribed height may be formed in at least one of the bottom part inner surface of the watering container which supports the net | network through which the support body was penetrated, and the surface of a support body. As a result, a gap of a predetermined size suitable for the outflow of liquid is secured between the bottom inner surface of the water spray container and the surface of the support, corresponding to the height of the convex portion, over the entire horizontal width of the net. can do.

  That is, the support is pressed against the inner surface of the bottom of the water spray container by the load of the net and the net of the part is crushed, or the net of the part is deformed due to the change over time due to the tensile load, and the passage through which the liquid flows is blocked. It can suppress that it peels. As a result, the required amount of liquid can flow down substantially evenly over the entire width of the net.

  In addition, a pair of flange portions may be formed at the edge portions of the outflow holes facing each other via the net so as to extend downward from the edges so as to be parallel to each other and sandwich the net. As a result, it is possible to enhance the effect of causing the liquid to flow out substantially uniformly and to suppress the scattering of the liquid, so that it is possible to increase the amount of liquid flowing down.

  Moreover, you may provide the spacer clamped by this flange part between the inner surfaces of a pair of opposing flange part. Thereby, since the distance between the inner surfaces of a flange part can be ensured suitably, the flowing-down amount of a liquid can be adjusted suitably. Further, since the distance between the inner surfaces of the flange portions can be set uniformly over the entire width of the net, it is possible to flow the liquid substantially evenly.

  Moreover, the convex part which protrudes by predetermined | prescribed height may be formed in the inner surface which opposes via the net | network of a pair of flange part. The distance between the inner surfaces of the flange portions can be suitably ensured also by forming the convex portions on the inner surfaces of the flange portions.

  Further, the water spray container may be formed in a substantially cylindrical shape. That is, the watering container may be formed in a substantially sealed container shape whose upper part is not open. As a result, foreign matter such as dust and dead leaves can be prevented from entering the watering container, so that it is possible to suppress a decrease in the amount of liquid flow and non-uniform flow caused by dust and the like.

  Further, the net may be provided with a fabric portion that has a smaller opening than the net portion that is the main land of the net and extends in the horizontal direction with a predetermined width. For example, the liquid flowing out from the water spray container can be spread uniformly by providing the dough portion in the vicinity of the upper end side of the net inserted into the water spray container.

  In addition, by providing a dough portion at the middle portion of the net suspended from the water spray container, it is possible to suppress the uneven flow of the liquid in the process of flowing down the net and to make the wet state of the net uniform. it can.

Hereinafter, a net type deodorizing apparatus according to an embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 (A) is a front view showing a schematic configuration of a net-type deodorizing apparatus 1 according to an embodiment of the present invention, and FIG. 1 (B) schematically shows a deodorizing effect of the net 3 in the net-type deodorizing apparatus 1. It is sectional drawing shown in FIG. (AA sectional view taken on the line in FIG. 1 (A)).

  The net-type deodorizing apparatus 1 is an apparatus for suppressing the emission of bad odors from an open type barn, a compost house, a food factory, and the like. As shown in FIG. 1 (A), a net-type deodorizing apparatus 1 includes a water spray container 2 capable of storing a liquid L such as a deodorizing liquid, a net 3 suspended from the water spray container 2 and causing the liquid L to flow down, And a collection container 4 that is disposed below the net 3 and collects the liquid L.

  The water sprinkling container 2 is disposed above an opening or the like of a foul odor releasing facility or the like, supports the net 3, and supplies the liquid L to the net 3. That is, the liquid L flowing out of the water spray container 2 flows down along the net 3 that is suspended by the water spray container 2. That is, the net 3 is wetted by the liquid L, and a liquid film of the liquid L is formed on the surface of the net 3.

  The net 3 is formed of, for example, a synthetic fiber such as polyester, polyethylene, or polypropylene, and has a net portion 10 that can be ventilated in a substantially mesh shape as a main area, and is extended to an opening portion or the like of a malodorous emission facility. The material of the net 3 is preferably a synthetic fiber from the viewpoint of durability, processability, etc., but is not limited to this, and may be other fibers such as natural fiber, regenerated fiber, semi-synthetic fiber, etc. . The opening of the net portion 10 of the net 3 is, for example, about 1 mm to 15 mm. In addition, from the viewpoint of obtaining a suitable deodorizing effect while ensuring the air permeability of the net 3, the opening of the net portion 10 is preferably about 5 mm to 10 mm.

  As the mesh shape of the net 3, various forms such as a substantially rectangular shape and a substantially hexagonal shape can be adopted. Further, the net 3 is provided with a fabric portion 11 having a smaller opening than the net portion 10 of the net 3 and extending in the horizontal direction with a predetermined width.

  The collection container 4 is provided below the net 3 and collects the liquid L flowing down from the net 3. The net-type deodorizing apparatus 1 connects the recovery container 4 and the sprinkling container 2, and supplies the liquid L, which is provided in the circulation path 7 and is recovered in the recovery container 4, to the sprinkling container 2. A storage tank 6 for storing the liquid L may be provided. Thereby, the solution L can be circulated and the wet state of the net | network 3 can be maintained suitably.

  Here, the liquid L is a deodorizing liquid or the like, for example, an aqueous citric acid solution having a concentration of about 0.5% by mass. As schematically shown in FIG. 1 (B), the odor typified by ammonia from the inside of the odor emission facility is absorbed and neutralized by the liquid L flowing along the net 3. Thereby, the leak of the odor outside a facility is suppressed.

  In addition, as the liquid L, deodorizing liquids containing various organic acid aqueous solutions such as citric acid and malic acid and other various deodorizing components can be used. Further, a solution containing an insecticidal component, a pest repellent component, a sterilizing / antibacterial component and the like in the liquid L may be used. Thereby, the net-type deodorizing apparatus 1 can be used for various uses such as insecticide, pest repellent, sterilization and antibacterial.

  Moreover, in the net-type deodorizing apparatus 1, the cooling effect by the evaporation of the liquid L flowing down the net 3 is obtained. Therefore, water may be used as the liquid L when the purpose is only to obtain a cooling effect. Thereby, the net-type deodorizing apparatus 1 can be used as a cooling / heat-proofing apparatus.

  FIG. 2 is a perspective view showing a schematic configuration of the net type deodorizing apparatus 1. As shown in FIG. 2, the water spray container 2 and the collection container 4 are formed in a substantially cylindrical shape (substantially hexagonal cylindrical shape) having a substantially hexagonal cross section and extending in the horizontal direction along the upper end side or the lower end side of the net 3. Is done.

  The sprinkling container 2 and the collection container 4 are sealed at both ends by lid members (not shown). As a result, a space for storing the liquid L flowing down to the net 3 is formed inside the sprinkling container 2, and a space for receiving the liquid L flowing down from the net 3 is formed inside the recovery container 4.

  Thus, since the sprinkling container 2 and the collection container 4 are formed in a substantially sealed container shape whose upper part is not completely opened, foreign matters such as dust and dead leaves enter the inside of the sprinkling container 2 and the collection container 4. Can be prevented. Thereby, the fall of the amount of flow of the liquid L resulting from penetration | invasion of dust etc. and the non-uniform | heterogenous flow can be suppressed.

  The water spray container 2 and the collection container 4 are each constituted by a plurality of constituent members molded from fiber reinforced resin or the like, and these constituent members are formed with flange portions and the like that allow mutual coupling. In addition, in FIG. 2, illustration of each structural member, a flange part, etc. is abbreviate | omitted.

  The water spray container 2 is provided with a water supply port 28 for supplying the liquid L to the internal space. The water supply port 28 is connected to the circulation path 7 connected to the pump 5 and is provided inside the water spray container 2. Connected to the watering pipe 29.

  The water spray pipe 29 is a substantially tubular member extending in the width direction of the net 3, that is, in the horizontal direction inside the water spray container 2. A large number of through holes through which the liquid L passes are formed in the pipe wall of the water spray pipe 29. Further, as the sprinkling pipe 29, a porous pipe or the like in which a large number of voids that allow passage of the liquid L from the inside of the pipe to the outside of the pipe may be used. By providing the sprinkling pipe 29, the liquid L can be supplied substantially evenly over the entire width of the net 3.

  A slit-like outflow hole 30 that extends in the horizontal width direction of the net 3 and allows the liquid L to flow out is formed at the bottom 21 of the water spray container 2. The vicinity of the upper end side of the net 3 is inserted into the outflow hole 30.

  In addition, a substantially tubular support body 15 extending in the width direction of the net 3 is disposed inside the water spray container 2. The support 15 has a shape that cannot pass through the outflow hole 30. Although various forms can be adopted as the support 15, for example, a substantially rod-like or substantially tubular member thicker than the opening width of the outflow hole 30 is preferable, and specifically, formed of a vinyl chloride resin or the like. A circular tube or the like can be used.

  The vicinity of the upper end side of the net 3 inserted through the outflow hole 30 is connected to and supported by the support 15. Specifically, a substantially cylindrical or substantially bag-like support insertion portion 12 extending along the upper end side is formed in the vicinity of the upper end side of the net 3, and the support 15 is formed of the support insertion portion 12. Is inserted.

  With such a configuration, the net 3 connected to the support 15 inside the water spray container 2 can be supported by the bottom 21 of the water spray container 2. That is, the vicinity of the upper end side of the net 3 can be stably supported over the entire width in the horizontal direction, and the net 3 can be suitably stretched while suppressing slack. Also, the connection work between the net 3 and the support 15 can be easily performed.

  Note that the vicinity of the upper end side of the net 3, specifically, the support body insertion portion 12 is formed so as to have a smaller opening than the net portion 10 of the net 3 (cloth portion). Specifically, the substantially cylindrical support insertion portion 12 is formed by folding and sewing the upper end portion of the fabric portion that is continuously knitted or woven continuously from the upper end portion of the net portion 10. The

  In addition, as the fabric portion constituting the vicinity of the upper end side of the net 3, various woven fabrics or knitted fabrics made of synthetic fibers or the like that are separately formed are sewn and used near the upper end portion of the net portion 10. Is also possible. Various forms can be adopted as the weaving method (knitting method) of the fabric portion. The fabric portion is not necessarily limited to a cloth material or the like in which fibers are regularly woven (knitted), and may be a non-woven fabric or the like that is intertwined with fibers and finished into a cloth shape. By providing the dough portion in the vicinity of the upper end side of the net 3 in this manner, an effect of making the amount of the liquid L flowing out of the water spray container 2 uniform in the width direction of the net 3 can be obtained.

  A through hole 31 through which the vicinity of the lower end side of the net 3 is inserted is formed in the upper part of the collection container 4. In the vicinity of the lower end side of the net 3 inserted through the through hole 31, a substantially cylindrical or substantially bag-like lower support insertion portion 13 extending along the lower end side is formed. The lower support 17 is inserted.

  The lower support 17 is a substantially rod-like or substantially tubular member extending in the horizontal width direction of the net 3, and is, for example, a circular pipe made of vinyl chloride resin or the like. The lower support 17 is in a form incapable of passing through the through hole 31 of the collection container 4, specifically, wider than the opening width of the through hole 31, supports the vicinity of the lower end side of the net 3, and is caused by wind or the like It has a function to prevent the net 3 from turning up. Thereby, the suitable stretched state of the net 3 is maintained.

  In addition, a pair of flange portions 32 are formed at the edge portions of the through holes 31 facing each other via the net 3 so as to extend upward in parallel from the respective edge portions so as to sandwich the net 3. Also good. Thereby, the vicinity of the lower end side of the net 3 can be suitably supported while suppressing the scattering of the liquid L. Further, as described above, since the collection container 4 is formed in a substantially sealed container shape, entry of foreign matter into the collection container 4 is suppressed.

FIG. 3 is a cross-sectional view (cross-sectional view taken along the line BB shown in FIG. 1 (A)) in the vicinity of the watering container 2 of the net-type deodorizing apparatus 1.
As shown in FIG. 3, the water spray container 2 is configured by combining a case member 20A and a case member 20B as constituent members.

  Specifically, the case members 20 </ b> A and 20 </ b> B each have an upper flange portion 24 and a lower flange portion 23, and extend in the horizontal width direction of the net 3 with a substantially cross-sectional hat shape. The flange portion 24 and the flange portion 23 of the case member 20 </ b> A and the case member 20 </ b> B are abutted with each other and fixed by fastening members 40 such as bolts and nuts to form a cylindrical body constituting the water spray container 2.

  Here, the flange portions 23 of the case member 20A and the case member 20B are assembled so as to sandwich the vicinity of the upper end side of the net 3 and the inner surfaces 23a of each other are separated by a predetermined distance. As a result, a slit-like outflow hole 30 that extends in the horizontal width direction of the net 3 and allows the liquid L to flow out is formed in the bottom 21 of the water spray container 2. As described above, the vicinity of the upper end side of the net 3 is sandwiched between the outflow holes 30 and is connected to and supported by the support 15 inside the water spray container 2.

  Thus, by forming the outflow hole 30 in the bottom 21 of the water spray container 2, the liquid L can flow down from the outflow hole 30 using gravity. Therefore, it is possible to efficiently flow a large amount of the liquid L as compared with the conventional technique in which the liquid is sucked and then flowed down using the capillary phenomenon. As a result, the entire net 3 can be moistened substantially uniformly, the amount of liquid L flowing down can be increased, and the deodorizing effect can be enhanced.

  Here, the water spray container 2 is formed in a substantially hexagonal cross section, and the bottom 21 is formed so as to incline downward from both sides toward the center outflow hole 30. Thereby, the outflow of the liquid L can be made favorable. In addition, as a cross-sectional shape of the water spray container 2, for example, various other shapes such as a circular shape, a semicircular shape, and a rhombus shape can be adopted, but the bottom portion is a shape that is inclined downward toward the outflow hole 30. It is preferable.

  Further, the vicinity of the upper end side of the net 3 is inserted into the outflow hole 30 and connected to the support 15 disposed inside the water spray container 2, so that the liquid L in the water spray container 2 flows along the net 3. It flows out from the outflow hole 30. Therefore, it is possible to increase the flow amount while suppressing the scattering of the liquid L.

  Further, the pair of flange portions 23 are continuously extended from the edge portions of the outflow holes 30 facing each other via the net 3 so as to be parallel to each other so as to sandwich the net 3. The effect of flowing out almost evenly is enhanced. Further, since the flange portion 23 is formed, scattering of the liquid L is suppressed, so that it is possible to increase the flow amount of the liquid L.

  In addition, as for the above-mentioned cloth | dough part (support body insertion part 12) formed in the upper end side vicinity of the net | network 3, it is desirable that the lower part is pinched | interposed into a pair of flange part 23. FIG. Thereby, the effect which distribute | distributes the liquid L which flows out from the water spray container 2 substantially uniformly in the width direction of the net | network 3 is heightened.

  In addition, a spacer 27 sandwiched between the flange portions 23 is provided between the inner surfaces 23 a of the opposing flange portions 23. The spacer 27 is a substantially annular member through which the fastening member 40 is inserted, and is, for example, an O-ring or a washer.

  By providing the spacers 27 between the flange portions 23, the opening width of the outflow holes 30 and the distance between the inner surfaces 23a of the flange portions 23 can be suitably ensured, so that the amount of liquid L flowing down is suitably adjusted. Can do. In addition, since the opening width of the outflow hole 30 and the distance between the inner surfaces 23a of the flange portion 23 can be set substantially evenly over the entire width of the net 3, the liquid L can flow substantially evenly.

  Instead of the configuration in which the spacer 27 is provided between the flange portions 23, a convex portion (not shown) protruding at a predetermined height may be formed on the inner surface 23a facing the net 3 of the flange portion 23. good. Also by forming a convex portion on the inner surface 23a of the flange portion 23, the opening width of the outflow hole 30 and the distance between the inner surface 23a of the flange portion 23 can be suitably ensured.

  Moreover, as mentioned above, the water spray container 2 is formed so that the liquid L can be stored. Therefore, a predetermined amount of the liquid L can be stored and flowed down inside the water spray container 2, so that the liquid L can be supplied substantially evenly in the width direction of the net 3.

  Further, the pump 5 (see FIG. 2) can be intermittently operated by a control device (not shown). Specifically, the pump 5 is operated to send the liquid L to the watering container 2, and when the amount of the liquid L stored in the watering container reaches a predetermined amount, the pump 5 is stopped and the supply of the liquid L is stopped. . When the liquid L flows from the sprinkling container 2 and the amount of the liquid L in the sprinkling container 2 falls below a predetermined amount, the pump 5 is operated to restart the supply of the liquid L. Thereby, the operation time of the pump 5 can be reduced and the power consumption can be reduced while flowing a sufficient amount of the liquid L through the net 3 substantially evenly. The operation and stop of the pump 5 may be switched at a predetermined time using a timer means (not shown) or the like.

  FIG. 4 is a perspective view showing the internal structure of the case member 20 </ b> A constituting the water spray container 2 of the net-type deodorizing apparatus 1. As shown in FIG. 4, a convex portion 22 protruding at a predetermined height is formed on the inner surface of the case member 20A.

  The convex portion 22 protrudes from the inner surface 21a of the bottom portion 21 that supports the net 3 (see FIG. 3) through which the support 15 (see FIG. 3) is inserted, and continues to the upper portion of the inner surface of the case member 20A. A plurality of locations are formed in the width direction. By forming the convex portion 22 continuously from the bottom portion 21 to the upper portion of the case member 20A, the rigidity of the case member 20A is increased and sufficient strength for supporting the net 3 is ensured.

  In addition, fixing holes 25 for fixing the case member 20B (see FIG. 3) are formed in the flange portions 23 and 24 of the case member 20A. The basic shape of the case member 20B joined to the case member 20A is the same as that of the case member 20A (substantially symmetrical shape), and the convex portion 22 is formed on the inner surface.

FIG. 5 is a longitudinal sectional view (cross-sectional view taken along the line CC in FIG. 3) showing the vicinity of the contact portion between the bottom 21 of the water spray container 2 of the net-type deodorizing apparatus 1 and the support 15.
As described above, a plurality of convex portions 22 having a predetermined height are formed on the inner surface 21a of the bottom portion 21 of the water spray container 2 in the width direction of the net 3, so that the convex portions 22 are formed on the net as shown in FIG. 3 to contact the support 15.

  Thereby, the liquid L (FIG. 3) corresponds to the height of the convex portion 22 between the inner surface 21a of the bottom portion 21 of the water spray container 2 and the surface of the support 15 over the entire width of the net 3 in the horizontal direction. A gap having a predetermined size suitable for the outflow of the reference) can be secured.

  That is, the support 15 is pressed against the inner surface 21a of the bottom 21 of the water spray container 2 by the load of the net 3, and the net 3 of the part is crushed, or the net 3 is deformed by the change with time due to the tensile load, and the liquid It is possible to suppress the passage where L flows down from being blocked by forming the convex portion 22. As a result, a necessary amount of the liquid L can flow down substantially uniformly.

  Instead of or in addition to the configuration in which the convex portion 22 is formed on the inner surface 21 a of the bottom portion 21, a convex portion that protrudes at a predetermined height may be formed on the surface of the support 15. Even with such a configuration, the flow path of the liquid L can be suitably secured.

  FIG. 6 (A) is a perspective view showing the vicinity of the end of the fabric portion 11 of the net-type deodorizing apparatus (detailed portion D shown in FIG. 1 (A)), and FIG. It is a perspective view which shows the edge part vicinity (equivalent to the D section shown to FIG. 1 (A)) of the fabric part 111 which is an example.

  As already described with reference to FIG. 1A, the net 3 is provided with a fabric portion 11 having a smaller opening than the net portion 10 of the net 3 and extending in the horizontal direction with a predetermined width. As shown in FIG. 6A, the fabric portion 11 has a substantially band shape, and is continuously knitted or woven integrally with the net portion 10 of the net shape of the net 3.
