Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a handheld rapid detection device for packing wettability. Background Technology

[0002] Crossflow cooling towers lower the temperature of cooling water, providing a stable operating environment for cigarette factory equipment. Cooling towers typically consist of a large outer shell, internal packing, and a fan system. In the packing layer, the hot fluid transfers heat to the air through heat exchange when in contact with it, thus lowering the temperature of the hot fluid.

[0003] Cooling tower packing is a commonly used structural material in cooling towers, used to increase the surface area of ​​the cooling tower and enhance the cooling effect. The packing is composed of interconnected thin sheets, usually in a corrugated or wavy shape, which can effectively increase the air-water contact area and enhance the heat and mass transfer effect. The packing of cooling towers needs to be tested for wettability to assess whether the cooling tower is operating efficiently. Currently, there is no device on the market for testing the wettability of packing. Therefore, the inventor designed a handheld rapid testing device for packing wettability. Utility Model Content

[0004] The purpose of this invention is to provide a handheld rapid detection device for packing wettability, in order to solve the problem of the lack of a device for detecting the wettability of cooling tower packing in the prior art.

[0005] This utility model solves the above-mentioned technical problems through the following technical means: a handheld rapid detection device for packing wettability, including a blade and a handle, wherein the blade is installed at one end of the handle and is used to insert into the gap between packing sheets, and the side wall of the blade is provided with a compartment through the vertical direction, wherein a plurality of compartments are arranged at equal intervals along the length of the blade, and a test object is placed in the compartment, wherein the test object changes appearance when exposed to water.

[0006] By setting up the above structure, the operator holds the handle and inserts the inserter into the gap between the packing sheets. Cooling water from the wet area inside the packing drips onto the inserter and flows into the corresponding compartment. The inserter is then removed, and by observing the changes in the appearance of the sample, the depth of the dry area in the gap can be determined, resulting in high detection accuracy.

[0007] Furthermore, a baffle is provided on the top of the side wall of the compartment, which is used to block the object to be detected in the compartment, and several water inlet holes are opened through the baffle in the vertical direction.

[0008] By setting up the above structure, it is easy to guide the cooling water dripping between the packing plates into the compartment, while preventing the test object from sliding out from the top of the compartment during the insertion and removal of the inserter.

[0009] Furthermore, a cover plate is detachably connected to the bottom of the insert blade, and the cover plate has several drainage holes at each compartment position.

[0010] By setting up the above structure, the cover can be opened to remove the test items and add new test items. At the same time, the cover can prevent the test items from sliding out from the bottom of the cover, and the drain hole can prevent cooling water from accumulating in the compartment.

[0011] Furthermore, the insert blade has graduations along its length.

[0012] By setting up the above structure, it is easy for staff to intuitively read the depth of the wet / dry zone of the packing sheet.

[0013] Furthermore, the end of the insert knife furthest from the handle is tapered.

[0014] By setting the above structure, it is easy for the inserter to be smoothly inserted into the gap between the packing sheets.

[0015] Furthermore, at least one of the sidewalls of the insert is made of a transparent material.

[0016] By setting up the above structure, staff can easily observe which compartments have experienced changes in the appearance of the tested items.

[0017] Furthermore, a horizontal plate is provided between the insert knife and the handle. There are several insert knives, which are installed side by side at equal intervals on one side of the horizontal plate. The other side of the horizontal plate is fixedly connected to one end of the handle.

[0018] By setting up the above structure, the gaps between multiple packing sheets can be inserted and detected at the same time, improving detection efficiency.

[0019] Furthermore, the handle includes a first rod and a second rod slidably disposed within the first rod, a locking member is provided between the first rod and the second rod, and the outer end of the second rod extends out of the first rod and is connected to the cross plate.

[0020] By setting up the above structure, it is possible to insert and detect the gaps between packing sheets of different heights.

[0021] The beneficial effects of this utility model are as follows: When the operator holds the handle and inserts the inserter into the gap between the packing sheets, the cooling water in the wet area of ​​the packing falls onto the inserter and flows into the corresponding compartment. The appearance of the sample in the compartment changes. The inserter is then removed. By observing the change in the appearance of the sample, the depth of the dry area in the gap can be determined. The area ratio of the dry area to the wet area of ​​the packing sheet gap can then be calculated, and the packing sheet wetting rate of the gap can be obtained. The detection accuracy is high, and the operating status of the cooling tower can be accurately monitored. Attached Figure Description

[0031] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can understand the advantages and effects of this utility model from the content disclosed in this specification. It should be noted that the illustrations provided in the following embodiments are for illustrative purposes only and represent schematic diagrams, not actual pictures.

In the description of this utility model, it should be understood that if terms such as "upper", "lower", "left", "right", "front", "rear", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figure, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the figures are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances. In the description of this application, terms such as "first", "second", etc. are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] In related technologies, after the crossflow cooling tower is assembled, its packing plates are arranged vertically and tightly, fixed at equal intervals by through-pipe supports, with each plate spaced 20mm apart. Due to their non-removable nature and small spacing, it is impossible to directly measure their wetting rate. Therefore, the inventors designed a special tool to measure the wetting rate of the packing.

[0034] like Figure 1-7 As shown in the figure, this utility model embodiment proposes a handheld rapid detection device for packing wettability, including a blade 1 and a handle 2. The blade 1 is installed at one end of the handle 2 and is used to insert into the gap between the packing sheets. A compartment 3 is vertically oriented through the top side wall of the blade 1. Several compartments 3 are evenly spaced along the length of the blade 1, and each compartment 3 contains a test object (not shown in the figure). The test object changes appearance when it comes into contact with water. In practice, the test object can be a customized moisture test strip, which changes color (e.g., yellow → blue) when it comes into contact with water. In this embodiment, the test object is color-changing silica particles, such as orange silica particles, which change color from orange to dark green when they come into contact with water. It has the advantages of obvious color change, non-toxicity, and reusability, and is suitable for scenarios where long-term testing of packing material in crossflow cooling towers in cigarette factories is required.

[0035] A stop block 4 is provided on the top of the side wall of the compartment 3. The stop block 4 does not protrude outside the insert 1. The stop block 4 is used to block the test object in the compartment 3 to prevent the test object from sliding out from the top of the compartment 3 during the test. Several water inlet holes 5 are opened through the stop block 4 in the vertical direction. In this embodiment, the water inlet holes 5 connect the inside of the compartment 3 with the outside. Two stop blocks 4 are provided in each compartment 3. The two stop blocks 4 are symmetrically arranged on two opposite side walls of the compartment 3. The cross section of the stop block 4 is a right triangle. The stop block 4 is fitted to the side wall of the compartment 3. The surface where the inclined side of the stop block 4 is located slopes from the edge of the compartment 3 to the middle of the compartment 3 from top to bottom. A strip slit 6 is reserved between the two stop blocks 4 to facilitate the staff to observe the inside of the compartment 3. At the same time, it is convenient for the cooling water to drip onto the test object in the compartment 3 after being guided by the inclined surface of the stop block 4.

[0036] The bottom of the inserter 1 is detachably connected to a cover plate 7. The cover plate 7 has several drainage holes 11 at each compartment 3. In this embodiment, elastic blocks 8 are provided at the four corners of the cover plate 7, and four slots 9 are provided on the side wall of the inserter 1. The elastic blocks 8 and the slots 9 are snapped together. The cover plate 7 can prevent the test object from sliding out of the compartment 3. By removing the cover plate 7, the test object in the compartment 3 can be taken out. The drainage holes 11 can prevent cooling water from accumulating in the compartment 3.

[0037] The inserter 1 has a scale 10 along its length, which makes it easy for staff to read the depth of the wet zone 16 / dry zone 15 of the packing sheet.

[0038] The end of the inserter 1 away from the handle 2 is tapered, which makes it easy for the inserter 1 to be inserted smoothly into the gap between the packing sheets.

[0039] At least one inserter 1 has a sidewall made of transparent material. In this embodiment, the sidewall with scale 10 is made transparent, and the scale 10 is read while the staff observes the changes in the object being tested.

[0040] A horizontal plate 12 is provided between the inserter 1 and the handle 2. There are several inserters 1, which are fixedly installed side by side at equal intervals on one side of the horizontal plate 12. The other side of the horizontal plate 12 is fixedly connected to one end of the handle 2. In this embodiment, by setting multiple inserters 1, the gaps between multiple filler pieces can be inserted and detected at one time, thereby improving the detection efficiency. In this embodiment, two adjacent blades can be inserted into the gap between two adjacent filler pieces.

[0041] The handle 2 includes a first rod 21 and a second rod 22 slidably disposed within the first rod 21. A locking element is provided between the first rod 21 and the second rod 22. The outer end of the second rod 22 extends out of the first rod 21 and is connected to the cross plate 12. In this embodiment, the second rod 22 is L-shaped. The vertical section of the second rod 22 can be housed inside the first rod 21, and the horizontal section is fixedly connected to the side wall of the horizontal plate 12 facing away from the insert 1, so that the length direction of the insert 1 is perpendicular to the axis of the handle 2. The locking component includes a fixing ring 13 and a bolt 14. The fixing ring 13 is fixedly sleeved on the top of the first rod 21. The side wall of the first rod 21 is provided with a through hole for the bolt 14 to pass through. The fixing ring 13 is provided with a threaded hole for the bolt 14 to pass through. The through hole communicates with the interior of the first rod 21. One end of the bolt 14 passes through the threaded hole and the through hole in sequence and abuts against the outer wall of the second rod 22 to lock and fix the first rod 21 and the second rod 22. By turning the bolt 14, the length of the handle 2 can be adjusted, and the gap between the filler pieces of different heights can be inserted for detection.

[0042] In the above embodiments, the length of the insert 1 is preferably 30cm.

[0043] Working principle:

[0044] During use, staff encapsulate orange silica particles in permeable non-woven bags, preparing a sufficient number of bags. One bag is placed in each compartment 3, and the cover 7 is closed and secured with clips. A layer of packing sheets is selected vertically, and the test is performed from left to right. The staff adjusts the handle 2 to a suitable length and, holding the handle 2, horizontally inserts all the inserts 1 into the gaps between the packing sheets. Cooling water from the wet area 16 of the packing sheet drips vertically into the compartment 3 below. After 20 seconds, the sample is removed, and the particle color is observed. The change (orange to dark green) and the observation and recording of the numerical scale 10 on the side of each inserter 1 are recorded. The cover plate 7 is opened, the discolored particles are removed, and the inserter 1, cover plate 7, and inner wall of compartment 3 are wiped dry with a towel or paper towel. New particles are put in, cover plate 7 is closed and fixed, and all gaps in the layer are inserted for testing in sequence. Then the dry area 15 and wet area 16 are calculated and compared with the horizontal cross-sectional area of ​​the packing in the layer to obtain the packing wetness rate. The packing wetness rate = (packing cross-sectional area - dry area 15 of the packing cross-section) / packing cross-sectional area.

[0045] After testing, the non-woven fabric containing the color-changing particles is fed into a drying device for overall drying. After five minutes of drying, the silica particles automatically turn back to orange, facilitating subsequent reuse. The rapid detection device for the wettability of crossflow cooling tower packing provided by this invention can conveniently and quickly detect the wettability of the packing, is reusable, and has low cost. It improves the efficiency and accuracy of cooling tower packing wettability detection, precisely monitors the operating status of the cooling tower, allows for preventative cleaning of the packing, maintains efficient cooling tower operation, enhances cooling tower heat dissipation, and reduces energy consumption of the cooling system.

[0046] It should be noted that, to reduce measurement errors, the inventors took multiple measurements at equal intervals in the vertical direction and averaged the results. Experimental analysis showed that the results from five or more measurements were closer. Therefore, while ensuring the accuracy of the measurement values ​​and simplifying the experimental procedure, a unified method of five measurements at equal intervals at different heights was adopted.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
