Description

Technical Field

[0001] This utility model relates to the field of dehumidification technology. In particular, this utility model relates to a dehumidification system for use in multiple spaces. Background Technology

[0002] This section provides background information relevant to this application, which does not necessarily constitute prior art.

[0003] Dehumidifiers are widely used in factories and laboratories with high environmental requirements. They are typically used to separate and remove water vapor from the air to obtain air with the desired dew point temperature. In meteorology, "dew point temperature" refers to the temperature at which air reaches saturation when cooled, while maintaining a constant water vapor content and air pressure. The lower the dew point temperature, the drier the air. In related technologies, to obtain air with a sufficiently low dew point temperature, a two-stage dehumidifier is usually used. When it is necessary to provide air with the same or different dew point temperatures to multiple spaces simultaneously, a two-stage dehumidifier is used independently for each space. However, this significantly increases energy consumption and manufacturing costs. Utility Model Content

[0004] The purpose of this invention is to solve one or more of the technical problems mentioned above.

[0005] Specifically, the purpose of this invention is to provide a dehumidification system that can reduce energy consumption and manufacturing costs.

[0006] This invention provides a dehumidification system for multiple usable spaces. The dehumidification system includes: a working gas pipeline through which a working gas flows; a primary dehumidification device including a primary drying unit and configured to receive the working gas via the working gas pipeline; and a plurality of secondary dehumidification devices, each connected downstream of the primary dehumidification device via the working gas pipeline to receive the working gas processed by the primary dehumidification device, and each secondary dehumidification device including a secondary drying unit.

[0007] In the dehumidification system provided by this invention, for multiple usage spaces, a single primary dehumidification device can be used to perform primary dehumidification of the working gas. The working gas, after primary dehumidification by this device, can be separately conveyed to multiple secondary dehumidification devices. In the secondary dehumidification devices, the working gas undergoes secondary dehumidification according to the needs of each usage space, thus meeting the requirements of different spaces. Therefore, it is unnecessary to use two separate dehumidification devices for each usage space, which reduces energy consumption and manufacturing costs.

[0008] Optionally, the dehumidification system further includes a regeneration gas pipeline through which regeneration gas flows, and the primary and secondary drying units are configured to receive the regeneration gas via the regeneration gas pipeline for regeneration. Thus, the primary and secondary drying units can be reused in a cyclical manner.

[0009] Optionally, the primary drying device and / or the secondary drying device is a dehumidifying rotor, which contains desiccant material. The rotation path of the dehumidifying rotor includes a drying section and a regeneration section. The drying section is in fluid communication with the working gas pipeline, and the regeneration section is in fluid communication with the regeneration gas pipeline. The rotation of the dehumidifying rotor facilitates the regeneration of the desiccant material.

[0010] Optionally, the regeneration gas pipeline is in fluid communication with the drying section in the rotation path of the secondary dryer to receive a portion of the working gas processed by the secondary dryer as the regeneration gas. Since the working gas processed by the secondary dryer contains less water vapor, the regeneration efficiency can be improved.

[0011] Optionally, the primary drying unit is connected to the secondary drying units downstream of them via the regeneration gas pipeline. In this way, the regeneration gas flowing from the secondary drying units can be collected at the primary drying unit through the regeneration gas pipeline, thereby regenerating the primary drying unit without the need for additional regeneration gas.

[0012] Optionally, the regenerated gas pipeline is configured to be in fluid communication with an external gas source to receive external gas from the external gas source as the regenerated gas.

[0013] Optionally, the regeneration gas pipeline includes independent first regeneration gas pipelines and multiple second regeneration gas pipelines. The first regeneration gas pipelines are in fluid communication with the regeneration section in the rotation path of the primary drying unit, and the second regeneration gas pipelines are in fluid communication with the regeneration section in the rotation path of the secondary drying unit. The independently configured first and second regeneration gas pipelines allow for independent adjustment of various parameters of both pipelines as needed.

[0014] Optionally, the primary dehumidification device includes a primary temperature regulating device, which is located upstream of the primary drying device on the working gas pipeline. The primary temperature regulating device includes a primary heater and a primary cooler. The secondary dehumidification device includes a secondary temperature regulating device located upstream of the secondary drying device on the working gas pipeline. The secondary temperature regulating device includes a secondary cooler. The primary heater and primary cooler allow for temperature adjustment of the working gas before it enters the primary drying device, as needed. The secondary cooler allows some water vapor in the working gas to condense before entering the secondary drying device, thereby improving the adsorption efficiency of the secondary drying device.

[0015] Optionally, the dehumidification system includes a return air duct, one end of which is in fluid communication with the operating space, and the other end of which is connected downstream of the primary dehumidifier and upstream of the secondary dehumidifier to the working gas duct. The return air duct allows for the recirculation of the working gas.

[0016] Optionally, the primary dehumidification device includes a primary filter, which is located upstream of the primary temperature control device on the working gas pipeline; and / or the secondary dehumidification device includes a secondary filter, which is located upstream of the secondary temperature control device and downstream of the connection between the return air pipeline and the working gas pipeline on the working gas pipeline. The primary and secondary filters can filter the working gas, preventing impurities carried in the working gas from clogging downstream components.

[0017] Optionally, the dehumidification system includes a regeneration gas heater, which is located upstream of the primary drying unit and / or the secondary drying unit on the regeneration gas pipeline. The regeneration gas heater can improve the regeneration efficiency of the primary and secondary drying units. Attached Figure Description

[0018] The foregoing and other features and characteristics of this application will become clearer from the following detailed description with reference to the accompanying drawings, which are merely illustrative and not necessarily drawn to scale. The same reference numerals are used in the drawings to indicate the same parts, in which:

[0019] Figure 1 This is a schematic diagram of a dehumidification system according to the first embodiment of the present invention; and

[0020] Figure 2 This is a schematic diagram of a dehumidification system according to the second embodiment of the present invention. Detailed Implementation

[0021] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The following description is exemplary in nature and is not intended to limit the present invention or its application or use.

[0022] This invention provides a dehumidification system. This dehumidification system can be used to supply gas with the same or different dew point temperatures to multiple spaces. The gas can be air or any other suitable gas, such as nitrogen. The spaces can be, for example, warehouses, battery production lines, etc.

[0023] Figure 1 This is a schematic diagram of a dehumidification system 100 according to a first embodiment of the present invention, which is used in two working spaces 200. For example... Figure 1 As shown, the dehumidification system 100 includes a working gas pipeline 110, a primary dehumidification unit 120, and two secondary dehumidification units 130. Optionally, the dehumidification system 100 also includes a regeneration gas pipeline 140 and a return air pipeline 150. The two secondary dehumidification units 130 and their corresponding regeneration gas pipelines 140 and return air pipelines 150 are configured identically for simplicity. Figure 1 Only one secondary dehumidification unit 130 and its corresponding regeneration gas pipeline 140 and return air pipeline 150 are shown using reference numerals in the accompanying drawings. The following will be combined with... Figure 1 A dehumidification system 100 according to the first embodiment of the present invention will be described in detail.

[0024] like Figure 1 As shown, a working gas pipeline 110 is disposed between the working gas source 210 and the operating space 200 for the flow of working gas. The working gas source 210 can be external air from a space other than the operating space 200 or other gas sources for providing other suitable gases. The working gas from the working gas source 210 flows to the operating space 200 via the working gas pipeline 110. The working gas pipeline 110 can be a multi-segment pipeline that is directly or indirectly connected.

[0025] like Figure 1As shown, the primary dehumidification device 120 is fluidly connected to the working gas source 210 downstream of it via a working gas pipeline 110, to receive working gas from the working gas source 210 via the working gas pipeline 110 and to perform primary dehumidification on the working gas. The primary dehumidification device 120 includes a primary dehumidification impeller 121 (as an example of a "primary drying device"). The primary dehumidification impeller 121 contains desiccant material to effectively absorb moisture from the working gas flowing through it. The primary dehumidification impeller 121 is rotatable about its central axis. The rotation path of the primary dehumidification impeller 121 may include a drying section and a regeneration section. The drying section is fluidly connected to the working gas pipeline 110. Figure 1 In this system, the drying section is located below the primary dehumidification rotor 121. The regeneration section is in fluid communication with the regeneration gas pipeline 140. Figure 1 In this configuration, the regeneration section is located above the primary dehumidification rotor 121. The desiccant material in the primary dehumidification rotor 121 effectively absorbs moisture from the working gas flowing through the primary dehumidification rotor 121 via the working gas line 110 as it rotates through the drying section. The desiccant material, having absorbed moisture from the working gas, is regenerated by the regeneration gas in the regeneration gas line 140, which is fluidly connected to the regeneration section, as the primary dehumidification rotor 121 further rotates through the regeneration section. This will be described in detail below.

[0026] Optionally, such as Figure 1 As shown, the primary dehumidification device 120 also includes a primary fan 122 disposed upstream of the primary dehumidification impeller 121 on the working gas pipeline 110. The primary fan 122 can provide power for the flow of working gas in the working gas pipeline 110, facilitating the flow of working gas to the primary dehumidification impeller 121.

[0027] Optionally, such as Figure 1 As shown, the primary dehumidification device 120 also includes a primary temperature regulating device 123, which is located upstream of the primary dehumidification impeller 121 and the primary fan 122 on the working gas pipeline 110. The primary temperature regulating device 123 includes a primary heater 123A and a primary cooler 123B. This is particularly advantageous when the working gas source 210 is external air from a space outside the operating space 200. The temperature of the external air is typically determined by the environment and varies depending on the region and season. The primary temperature regulating device 123 can adjust the temperature of the working gas before it enters the primary dehumidification impeller 121 as needed.

[0028] Optionally, such as Figure 1As shown, the primary dehumidification device 120 also includes a primary filter 124, which is installed upstream of the primary temperature regulating device 123 on the working gas pipeline 110. The primary filter 124 can be used to filter the working gas to prevent impurities carried in the working gas from clogging the downstream primary temperature regulating device 123, primary fan 122, and primary dehumidification impeller 121, etc.

[0029] like Figure 1 As shown, two secondary dehumidifiers 130 are connected to the primary dehumidifier 120 downstream of it via a working gas line 110 to receive the working gas processed (i.e., primary dehumidified) by the primary dehumidifier 120. The two primary dehumidifiers 130 perform secondary dehumidification on the received working gas according to the needs of their respective operating spaces 200 to obtain working gas with a desired dew point temperature. Each secondary dehumidifier 130 includes a secondary dehumidification impeller 131 (as an example of a "secondary drying device"). The secondary dehumidification impeller 131 contains desiccant material to effectively absorb moisture from the working gas flowing through it. The secondary dehumidification impeller 131 is rotatable about its central axis. The rotation path of the secondary dehumidification impeller 131 may also include a drying section and a regeneration section. The drying section is in fluid communication with the working gas line 110. Figure 1 In this system, the drying section is located below the secondary dehumidification rotor 131. The regeneration section is in fluid communication with the regeneration gas pipeline 140. Figure 1 In this configuration, the regeneration section is located above the secondary dehumidification rotor 131. As the desiccant material in the secondary dehumidification rotor 131 rotates and passes through the drying section, it effectively absorbs moisture from the working gas flowing through the working gas line 110. The desiccant material, having absorbed moisture from the working gas, is then regenerated by the regeneration gas in the regeneration gas line 140, which is fluidly connected to the regeneration section, as the secondary dehumidification rotor 131 further rotates and passes through the regeneration section. This will also be described in detail below.

[0030] Optionally, such as Figure 1 As shown, the secondary dehumidification device 130 also includes a secondary fan 132 disposed upstream of the secondary dehumidification impeller 131 on the working gas pipeline 110. The secondary fan 132 can provide power for the flow of working gas in the working gas pipeline 110, facilitating the flow of working gas to the secondary dehumidification impeller 131.

[0031] Optionally, such as Figure 1As shown, the secondary dehumidification device 130 also includes a secondary temperature regulating device 133, which is located upstream of the secondary dehumidification impeller 131 and the secondary fan 132 on the working gas pipeline 110. Unlike the primary temperature regulating device 123, the secondary temperature regulating device 133 may consist only of a secondary cooler. The working gas is cooled by the secondary cooler before entering the secondary dehumidification impeller 131, which can pre-condense some of the water vapor in the working gas, thereby improving the adsorption efficiency of the secondary dehumidification impeller 131.

[0032] The working gas, after secondary dehumidification by the secondary dehumidification device 130, can be transported to the corresponding operating space 200 via the working gas pipeline 110. Optionally, such as Figure 1 As shown, the dehumidification system 100 also includes a final-stage temperature regulating device disposed downstream of the secondary dehumidification device 130 on the working gas pipeline 110. The final-stage temperature regulating device includes a final-stage heater 161 and a final-stage cooler 162. For different usage spaces 200, it may be desirable to use working gases at different temperatures. The final-stage temperature regulating device can adjust the temperature of the working gas to be delivered to the usage space 200 according to actual needs.

[0033] like Figure 1 As shown, the working gas supplied to the operating space 200 can be returned to the corresponding secondary dehumidifier 130 for further dehumidification via the return air duct 150, thus recycling the working gas. One end of the return air duct 150 is in fluid communication with the operating space 200, and the other end of the return air duct 150 is connected to the working gas duct 110 downstream of the primary dehumidifier 120 and upstream of the secondary dehumidifier 130. The working gas returning from the operating space 200 may carry impurities again due to its passage through the operating space 200. Therefore, optionally, the secondary dehumidification device 130 also includes a secondary filter device 134, which is installed upstream of the secondary temperature regulating device 133 and downstream of the connection between the return air duct 150 and the working gas duct 110 on the working gas duct 110. The secondary filter device 134 is used to filter the working gas (especially the working gas returned via the return air duct 150) to prevent impurities carried in the working gas from clogging the downstream secondary temperature regulating device 133, secondary fan 132 and secondary dehumidification impeller 131, etc.

[0034] like Figure 1As shown, the regeneration gas line 140 is used for the flow of regeneration gas. The primary dehumidifying impeller 121 and the secondary dehumidifying impeller 131 can receive regeneration gas via the regeneration gas line 140 for regeneration. Specifically, the regeneration gas line 140 is in fluid communication with the regeneration section in the rotation path of the primary dehumidifying impeller 121 and the secondary dehumidifying impeller 131, and is used to supply regeneration gas to the regeneration section in the rotation path of the primary dehumidifying impeller 121 and the secondary dehumidifying impeller 131 to remove the moisture absorbed from the working gas by the desiccant in the primary dehumidifying impeller 121 and the secondary dehumidifying impeller 131, thereby allowing the primary dehumidifying impeller 121 and the secondary dehumidifying impeller 131 to be regenerated by the regeneration gas in the regeneration gas line 140. In other words, the desiccant in the primary dehumidifying rotor 121 and the secondary dehumidifying rotor 131 can continue to absorb water vapor in the working gas in the working gas pipeline 110 that is in fluid communication with the drying section when it rotates through the drying section again, so that the primary dehumidifying rotor 121 and the secondary dehumidifying rotor 131 can be used in a cycle.

[0035] More specifically, in the first embodiment of this utility model, as Figure 1As shown, the regeneration gas pipeline 140 includes a first regeneration gas pipeline 141 and two second regeneration gas pipelines 142. The first regeneration gas pipeline 141 is used for the primary dehumidification device 120. The two second regeneration gas pipelines 142 are used for one of the two secondary dehumidification devices 130. The first regeneration gas pipeline 141 and the two second regeneration gas pipelines 142 are independent pipelines. The independently configured first regeneration gas pipeline 141 and second regeneration gas pipelines 142 allow for independent adjustment of various parameters of the first regeneration gas pipeline 141 and second regeneration gas pipeline 142 according to actual needs, such as the regeneration gas flow rate. The first regeneration gas pipeline 141 is in fluid communication with a first regeneration gas source (not shown). The first regeneration gas source can be external air or other external gas sources. The first regeneration gas pipeline 141 is in fluid communication with the regeneration section in the rotation path of the primary dehumidification impeller 121 to transport the regeneration gas from the first regeneration gas source to the regeneration section in the rotation path of the primary dehumidification impeller 121. Optionally, the dehumidification system 100 further includes a first regeneration gas heater 171 disposed upstream of the primary dehumidification impeller 121 on the first regeneration gas line 141, to heat the regeneration gas in the first regeneration gas line 141 before it flows into the regeneration section in the rotation path of the primary dehumidification impeller 121, thereby improving the regeneration efficiency of the primary dehumidification impeller 121. The second regeneration gas line 142 is in fluid communication with a second regeneration gas source (not shown). The second regeneration gas source can be external air or other external gas sources. The second regeneration gas line 142 is in fluid communication with the regeneration section in the rotation path of the secondary dehumidification impeller 131, to deliver the regeneration gas from the second regeneration gas source to the regeneration section in the rotation path of the secondary dehumidification impeller 131. Optionally, the dehumidification system 100 further includes a second regeneration gas heater 172 disposed upstream of the secondary dehumidification impeller 131 on the second regeneration gas pipeline 142, to heat the regeneration gas in the second regeneration gas pipeline 142 before it flows into the regeneration section in the rotation path of the secondary dehumidification impeller 131, so as to improve the regeneration efficiency of the secondary dehumidification impeller 131.

[0036] The following will combine Figure 1 The working process of the dehumidification system 100 according to the first embodiment of the present invention is described.

[0037] like Figure 1As shown, outside air is drawn into the working gas pipeline 110 by the primary fan 122 installed on the working gas pipeline 110, and passes through the primary filter 124 to remove any impurities that may be carried in the working gas. The working gas then passes through the primary temperature regulating device 123, where the temperature of the working gas is adjusted to a suitable temperature. The working gas then flows into the primary dehumidification impeller 121 under the action of the primary fan 122, where the desiccant in the primary dehumidification impeller 121 absorbs moisture in the working gas, thus performing primary dehumidification. The working gas after primary dehumidification by the primary dehumidification impeller 121 can be divided into two parts and enter different secondary dehumidification devices 130 through different working gas pipelines 110. Before entering the secondary dehumidification device 130, the working gas after primary dehumidification by the primary dehumidification impeller 121 can be mixed with the working gas returning to the working gas pipeline 110 through the return air pipeline 150. The mixed working gas passes through a secondary filter 134 to remove any impurities that may be carried in the working gas (especially the working gas returned via the return air duct 150). The mixed working gas then passes through a secondary temperature control device 133, where some of the water vapor in the working gas is pre-condensed. The mixed working gas then flows into a secondary dehumidifier 131 under the action of a secondary fan 132, where the desiccant in the secondary dehumidifier 131 absorbs water vapor from the working gas, thus performing secondary dehumidification. The working gas, after secondary dehumidification by the secondary dehumidifier 131, is then temperature-controlled by a final-stage temperature control device before being transported to the corresponding operating space 200. Furthermore, during this process, the first regeneration gas from the first regeneration gas source is heated by the first regeneration gas heater 171 in the first regeneration gas duct 141 and then passes through a regeneration section in the rotation path of the primary dehumidifier 121 to remove the water vapor absorbed from the working gas by the desiccant in the primary dehumidifier 121, thereby regenerating the primary dehumidifier 121. Similarly, the second regeneration gas from the second regeneration gas source is heated by the second regeneration gas heater 172 in the second regeneration gas pipeline 142 and then passes through the regeneration section in the rotation path of the secondary dehumidification rotor 131 to remove the water vapor absorbed by the desiccant in the secondary dehumidification rotor 131 from the working gas, thereby regenerating the secondary dehumidification rotor 131.

[0038] In the dehumidification system 100 according to the first embodiment of this utility model, for two usage spaces 200, the same primary dehumidification device 120 can be used to perform primary dehumidification of the working gas. The working gas that has been primary dehumidified by the primary dehumidification device 120 can be respectively transported to two secondary dehumidification devices 130, where the working gas is further dehumidified according to the needs of the respective usage spaces 200, thereby meeting the different needs of the different usage spaces 200. Therefore, it is not necessary to use two separate dehumidification devices for each usage space 200, which can reduce energy consumption and manufacturing costs.

[0039] Figure 2 This is a schematic diagram of a dehumidification system 300 according to a second embodiment of the present invention, which is used in two working spaces 400. The dehumidification system 300 according to the second embodiment of the present invention is substantially the same as the dehumidification system 100 according to the first embodiment of the present invention. For example, as... Figure 2 As shown, the dehumidification system 300 also includes a working gas pipeline 310, a primary dehumidification device 320, and two secondary dehumidification devices 330. The working gas pipeline 310 is used for the flow of working gas. The primary dehumidification device 320 is configured to receive working gas via the working gas pipeline 310 and includes a primary dehumidification impeller 321 for primary dehumidification of the working gas. The two secondary dehumidification devices 330 are respectively connected to the primary dehumidification device 320 downstream of the primary dehumidification device 320 via the working gas pipeline 310 to receive working gas processed (i.e., primary dehumidified) by the primary dehumidification device 320, and each secondary dehumidification device 330 includes a secondary dehumidification impeller 331. Optionally, the dehumidification system 300 also includes a regeneration gas pipeline 340 and a return air pipeline 350. The dehumidification system 300 according to the second embodiment of the present invention differs from the dehumidification system 100 according to the first embodiment of the present invention only in the arrangement of the regeneration gas pipeline 340.

[0040] The following will combine Figure 2 The dehumidification system 300 according to the second embodiment of the present invention will be described. It should be noted that, for the sake of brevity, the parts of the dehumidification system 300 that are the same as those of the dehumidification system 100 will not be described here. Only the parts of the dehumidification system 300 that differ from those of the dehumidification system 100 will be described here, namely, the arrangement of the regeneration gas pipeline 340.

[0041] like Figure 2As shown, in the dehumidification system 300, on the one hand, the regeneration gas pipeline 340, which is in fluid communication with the regeneration section in the rotation path of the primary dehumidification rotor 321, and the regeneration gas pipeline 340, which is in fluid communication with the regeneration section in the rotation path of the secondary dehumidification rotor 331, are not independent gas pipelines; on the other hand, a portion of the working gas that has undergone secondary dehumidification treatment by the secondary dehumidification rotor 331 is used as the regeneration gas.

[0042] Specifically, such as Figure 2 As shown, the regeneration gas line 340 is in fluid communication with the drying section in the rotation path of the secondary dehumidification rotor 331 to receive a portion of the working gas processed (i.e., secondary dehumidification) by the secondary dehumidification rotor 331 as regeneration gas. Since this regeneration gas contains less water vapor, regeneration efficiency can be improved. More specifically, the drying section in the rotation path of each secondary dehumidification rotor 331 is connected to the regeneration section in the rotation path of that secondary dehumidification rotor 331 via the regeneration gas line 340 to guide a portion of the working gas subjected to secondary dehumidification by the secondary dehumidification rotor 331 from the drying section to the regeneration section, thereby regenerating the secondary dehumidification rotor 331. Therefore, each secondary dehumidification rotor 331 can be regenerated from a portion of the working gas processed by its own secondary dehumidification. The primary dehumidification rotor 321 is connected to the two secondary dehumidification rotors 331 downstream via the regeneration gas line 340. The regeneration gas flowing out from the regeneration section in the rotation path of the two secondary dehumidifying impellers 331 can be collected by the regeneration gas pipeline 340 at the regeneration section in the rotation path of the primary dehumidifying impeller 321, thereby regenerating the primary dehumidifying impeller 321. Optionally, the dehumidification system 300 includes regeneration gas heaters 370 corresponding to the number of primary dehumidifying impellers 321 and secondary dehumidifying impellers 331. These regeneration gas heaters 370 are respectively arranged upstream of the primary dehumidifying impellers 321 and secondary dehumidifying impellers 331 on the regeneration gas pipeline 340 to improve the regeneration efficiency of the primary dehumidifying impellers 321 and secondary dehumidifying impellers 331.

[0043] It should be noted that, although in the first and second embodiments of this utility model, the usable space is shown as two and the dehumidification system includes two secondary dehumidification devices, it is understood that, depending on actual needs, the dehumidification system provided by this utility model can be used for more usable spaces, such as three or four, and correspondingly, the dehumidification system provided by this utility model can include more secondary dehumidification devices, such as three or four.

[0044] In summary, in the dehumidification system provided by this invention, for multiple usage spaces, a single primary dehumidification device can be used to perform primary dehumidification of the working gas. The working gas, after primary dehumidification by this device, can be separately conveyed to multiple secondary dehumidification devices. In the secondary dehumidification devices, the working gas undergoes secondary dehumidification according to the needs of each usage space, thus meeting the requirements of different spaces. Therefore, it is unnecessary to use two separate dehumidification devices for each usage space, which reduces energy consumption and manufacturing costs.

[0045] It should be understood that various different implementation methods can be designed by combining or modifying different implementation methods and various technical features in different ways.

[0046] The foregoing description, in conjunction with specific embodiments, describes a preferred embodiment of a dehumidification system for multiple usage spaces according to the present invention. It is understood that the above description is exemplary and not restrictive, and various modifications and variations will arise in those skilled in the art from the above description without departing from the scope of the present invention. These modifications and variations are also included within the scope of protection of this application.
