Description

Technical Field

[0001] This utility model belongs to the field of cooling tower water collector design technology, specifically a high-temperature resistant M-type cooling tower water collector. Background Technology

[0002] In industrial circulating cooling systems, the cooling tower, as the core heat exchange equipment, directly affects the energy consumption and stability of the entire production structure through its operational efficiency and reliability. To reduce water loss and improve water reuse rates, water collectors are widely used at the top or outlet of cooling towers to capture liquid droplets entrained in the hot, humid airflow and return them to the circulation system. However, existing cooling tower water collectors suffer from the following technical problems: First, existing water collectors generally use a rigid fixing method to install the water storage tank, that is, the tank is directly welded or fastened to the inner wall of the shell by rigid bracket bolts. When the cooling tower is running at full load, the internal airflow temperature often reaches 60-90℃. The metal components deform due to thermal expansion, and the rigid constraint will concentrate the thermal stress at the weld or connection hole, which can easily cause fatigue cracks or even structural fractures.

[0003] Secondly, in actual operation, water tanks are prone to slight horizontal swaying due to uneven condensate distribution, asymmetrical thermal deformation, or external disturbances. Traditional methods often neglect to constrain such lateral degrees of freedom, or only use simple blocks or slots for rough limiting. This not only results in high frictional resistance and slow response, but also fails to achieve bidirectional symmetrical constraint. The swaying is directly transmitted to the water delivery pipe that passes through the shell, causing it to be subjected to repeated bending moments at the wall penetration point. Over time, this leads to aging and cracking of the sealing ring and fatigue cracking of the pipe joint, resulting in high-temperature water vapor leakage.

[0004] Third, some low-cost water collectors do not even have any water level protection measures. Once there is heavy rain, a sudden increase in cooling load, or abnormal operation of the water pump, the water tank will overflow rapidly, causing water waste; or the tank may be emptied due to continuous pumping, causing the pump to run dry, cavitation, or even the motor to burn out, resulting in high maintenance costs and the risk of production interruption.

[0005] To address this issue, a high-temperature resistant M-type cooling tower water collector is provided. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the prior art, this utility model provides a high-temperature resistant M-type cooling tower water collector to at least partially solve the above technical problems.

[0007] The technical solution adopted by this utility model is as follows: This utility model proposes a high-temperature resistant M-type cooling tower water collector, comprising: A high-temperature resistant protective shell has a working groove inside, in which a water storage tank is installed. The bottom of the water storage tank has four supporting circular plates at its four corners. A buffer damping rod is installed at the center of the bottom surface of each supporting circular plate. Limiting cylinders are installed on both sides of the buffer damping rods. Limiting grooves are opened in the limiting cylinders. Pressure-bearing blocks are installed in the limiting grooves. The top surface of the pressure-bearing blocks is connected to a limiting rod. The other end of the limiting rod is fixed to both sides of the center of the bottom surface of the corresponding supporting circular plate. Water supply pipes are installed on both sides of the top surface of the water storage tank. One end of the water supply pipe extends into the inside of the water storage tank, and the other end passes through the top surface of the high-temperature resistant protective shell and is connected to an external water pump. The end of the water supply pipe near the water storage tank is equipped with a secondary filter screen, and the end near the water pump is equipped with a primary filter screen. A flow limiting solenoid valve is also installed inside the water supply pipe. The bottom surface of the working tank is also provided with a flow-limiting solenoid valve closing module, which is electrically connected to the flow-limiting solenoid valve through a conductive line.

[0008] As a further embodiment of this utility model: the water storage tank is equipped with a filter plate inside, and L-shaped fixing rods are respectively provided at the four corners of the top surface of the filter plate. The vertical sections of the four L-shaped fixing rods are fixedly connected to the top corners of the filter plate, and the horizontal sections are fixedly connected to the inner wall of the water storage tank.

[0009] As a further embodiment of this utility model: the supporting circular plate is a circular metal plate with a diameter larger than the outer diameter of the buffer damping rod, and an embedding hole for installing the top end of the buffer damping rod is provided at the center of its bottom surface, and the bottom end of the buffer damping rod is fixedly connected to the bottom surface of the working groove.

[0010] As a further embodiment of this utility model: the limiting cylinder is a hollow cylindrical structure symmetrically arranged on both sides of the buffer damping rod, with its axis parallel to the buffer damping rod. The limiting groove is opened through the limiting cylinder along its axial direction. The pressure block is slidably disposed in the limiting groove, and its height is less than the depth of the limiting groove.

[0011] As a further embodiment of this utility model: one end of the limiting rod is vertically fixed to the center of the top surface of the pressure block, and the other end extends upward and is fixedly connected to both sides of the center of the bottom surface of the supporting circular plate. The limiting rod and the buffer damping rod are arranged in parallel.

[0012] As a further embodiment of this utility model: the aperture of the primary filter screen is larger than that of the secondary filter screen, the primary filter screen is located inside the inlet of the water supply pipe near the end of the water pump, and the secondary filter screen is located inside the outlet of the end of the water supply pipe that extends into the water storage tank.

[0013] As a further improvement of this utility model: the horizontal section of the L-shaped fixing rod is fixed to the inner wall of the water storage tank by welding or bolting, and its vertical section is connected to the top corner of the filter plate by countersunk screws.

[0014] Implementing the embodiments of this utility model will have the following beneficial effects: In this embodiment, the water storage tank is vertically flexibly connected to the damping rods via supporting circular plates at the four corners of the bottom. This connection not only bears the static weight of the tank and the water inside, but also effectively absorbs the dynamic loads caused by fan vibration, water flow impact, or start-up / shutdown transients during the operation of the cooling tower. The supporting circular plates are made of large-diameter circular metal plates, increasing the contact area with the bottom surface of the tank, evenly dispersing local stress, and preventing fatigue cracking caused by stress concentration. The limiting cylinders, pressure blocks, and limiting rods symmetrically arranged on both sides of each damping rod form a rigid lateral constraint structure: the axis of the limiting cylinder is strictly parallel to the damping rod, and the limiting groove is opened through it. The pressure block can slide within it, but its height is slightly less than the groove depth, which retains the small vertical gap required for thermal expansion and forms a rigid boundary in the horizontal direction. When the tank tends to move laterally due to thermal deformation or mass shift, the limiting rod quickly transmits the lateral force to the wall of the limiting cylinder through the pressure block, and the reaction force is ultimately borne by the bottom surface of the working groove, thereby suppressing shaking and ensuring the geometric stability of key parts such as the water supply pipe wall seal and filter plate connection.

[0015] In this embodiment, as condensate accumulates, the water storage tank slowly sinks due to gravity. When the water volume reaches the preset upper limit, the bottom surface of the tank gently contacts the flow-limiting solenoid valve closing module located on the bottom surface of the working tank. The module has a built-in pressure-sensitive element or micro switch, which sends a closing signal to the flow-limiting solenoid valve in the water supply pipe through the conduction line, thus automatically cutting off the water flow channel.

[0024] like Figures 1 to 8 As shown, a high-temperature resistant M-type cooling tower water collector includes: a high-temperature resistant protective shell 1, which has a working groove 9 inside. A water storage tank 2 is provided in the working groove 9. Supporting circular plates 3 are provided at the four corners of the bottom surface of the water storage tank 2. A buffer damping rod 4 is provided at the center of the bottom surface of each supporting circular plate 3. Limiting cylinders 5 are provided on both sides of the buffer damping rod 4. Limiting grooves 6 are provided in the limiting cylinders 5. Pressure blocks 8 are provided in the limiting grooves 6. Limiting rods 7 are connected to the top surface of the pressure blocks 8. The other end of the limiting rods 7 is fixed to the two sides of the center of the bottom surface of the corresponding supporting circular plate 3. Water supply pipes 13 are installed on both sides of the top surface of the water storage tank 2. One end of the water supply pipe 13 extends into the interior of the water storage tank 2, and the other end passes through the top surface of the high-temperature resistant protective shell 1 and is connected to an external water pump. The end of the water supply pipe 13 near the water storage tank 2 is equipped with a secondary filter screen 15, and the end near the water pump is equipped with a primary filter screen 14. A flow limiting solenoid valve 16 is installed inside the water supply pipe 13. A flow limiting solenoid valve closing module 10 is also installed on the bottom surface of the working tank 9. The flow limiting solenoid valve closing module 10 is electrically connected to the flow limiting solenoid valve 16 through a conduction line.

[0025] In a specific application of this utility model embodiment, when the cooling tower is running, the hot and humid airflow carries a large number of tiny water droplets into the water collector area. The water droplets settle and collect in the water storage tank 2 under the influence of gravity and inertia. As the collected water volume continues to increase, the total mass of the tank gradually rises. This increased load is then transferred to the buffer damping rod 4 via the supporting circular plates 3 at the four corners of the bottom. The buffer damping rod 4, while bearing the static load, also effectively attenuates the dynamic disturbances caused by water flow impact or equipment vibration, ensuring the tank sinks smoothly rather than shaking violently. During this process, the lateral constraint structure composed of the limiting cylinder 5, the pressure block 8, and the limiting rod 7 works synchronously—even if the tank exhibits a slight tendency to tilt due to uneven mass distribution or thermal expansion, the limiting rod 7 will promptly provide a reverse constraint force through the sliding of the pressure block 8 within the limiting groove 6, preventing lateral displacement of the tank from causing misalignment or sealing failure of the water supply pipe 13 interface, thereby ensuring the verticality and controllability of the entire sinking process.

[0026] As water continues to accumulate, the water storage tank 2 slowly descends under gravity until its bottom surface approaches and gently contacts the flow-limiting solenoid valve closing module 10 located on the bottom surface of the working tank 9. The flow-limiting solenoid valve closing module 10 integrates a pressure-sensitive element or microswitch. Once it detects that the contact pressure applied to the bottom surface of the tank reaches a preset threshold (corresponding to the maximum safe water storage capacity), it immediately sends a closing command to the flow-limiting solenoid valve 16 inside the water supply pipe 13 via a transmission line. The flow-limiting solenoid valve 16 then actuates, cutting off the water supply pipe 13 and preventing the external water pump from continuing to draw water from the water storage tank 2.

[0027] In one embodiment, a filter plate 11 is provided inside the water storage tank 2. L-shaped fixing rods 12 are provided at the four corners of the top surface of the filter plate 11. The vertical sections of the four L-shaped fixing rods 12 are fixedly connected to the top corners of the filter plate 11, and the horizontal sections are fixedly connected to the inner wall of the water storage tank 2. The horizontal sections of the L-shaped fixing rods 12 are fixed to the inner wall of the water storage tank 2 by welding or bolting, and their vertical sections are connected to the top corners of the filter plate 11 by countersunk screws.

[0028] In a specific application of this utility model embodiment, when the hot and humid airflow discharged from the cooling tower carries condensate droplets into the water collector, the water settles into the bottom area of ​​the water storage tank 2 due to gravity. During this process, some of the water contains aging debris from the cooling tower packing, dust particles from the air, microbial metabolic products, or tiny sediments precipitated from the circulating water structure. If these impurities are not intercepted, they will enter the water supply pipe 13 with the water flow, not only clogging the flow-limiting solenoid valve 16 or the secondary filter screen 15, but also causing wear on the downstream water pump impeller, and even affecting the heat exchange efficiency of the entire cooling structure.

[0029] Furthermore, the filter plate 11 is horizontally arranged in the upper part of the water storage tank 2, ensuring sufficient volume for temporary storage of collected condensate while also ensuring that the water flow must penetrate the pores of the filter plate 11 before entering the water supply pipe 13, thereby achieving effective interception. However, under high-temperature conditions (especially when the cooling tower is operating at full or overload), the inner wall and internal components of the water storage tank 2 will undergo slight deformation due to the difference in thermal expansion coefficients; at the same time, water flow impact, equipment vibration, and frequent start-stop will also apply dynamic loads to the internal components.

[0030] Specifically, the filter plate 11 is rigidly anchored around the entire circumference by L-shaped fixing rods 12 arranged at the four corners. Each L-shaped fixing rod 12 is made of high-temperature resistant alloy material and has a right-angle bend: the vertical section extends downward and is firmly connected to the four corners of the top surface of the filter plate 11. It is usually fastened with countersunk screws so that the connection part is flush with the surface of the filter plate 11 to avoid the formation of dead corners for water flow disturbance or impurity accumulation; the horizontal section extends laterally along the inner wall of the water storage tank 2 and is permanently fixed to the inner wall of the tank by welding or high-strength bolts.

[0031] Meanwhile, when the filter plate 11 needs to be replaced or cleaned, the operator only needs to remove the countersunk screws at the four corners to remove the filter plate 11 together with the L-shaped fixing rod 12 as a whole (if the horizontal section is bolted), or remove the filter plate 11 separately (if the horizontal section is welded, the filter plate 11 can still be pulled out from the top), without damaging the water storage tank 2 or disassembling the entire water collector. The water that has been initially purified by the filter plate 11 flows into the clean area at the bottom of the tank, and is then pumped out by the water pump through the water delivery pipe 13. At this time, if the filter plate 11 shifts due to insecure fixing, it will not only reduce the filtration efficiency, but also cause unfiltered water to flow directly around to the inlet of the water delivery pipe 13, causing the primary and secondary filter screens 15 to quickly become clogged, which in turn triggers the abnormal closure of the flow limiting solenoid valve 16, affecting the normal operation of the structure.

[0032] In one embodiment, the supporting circular plate 3 is a circular metal plate with a diameter larger than the outer diameter of the buffer damping rod 4, and an insert hole for installing the top end of the buffer damping rod 4 is provided at the center of its bottom surface. The bottom end of the buffer damping rod 4 is fixedly connected to the bottom surface of the working groove 9. The limiting cylinder 5 is a hollow cylindrical structure symmetrically arranged on both sides of the buffer damping rod 4, and its axis is parallel to the buffer damping rod 4. The limiting groove 6 is opened through the limiting cylinder 5 along the axial direction. The pressure block 8 is slidably disposed in the limiting groove 6, and its height is less than the depth of the limiting groove 6.

[0033] In a specific application of this utility model embodiment, when the cooling tower is in operation, the temperature of the hot and humid airflow it discharges can reach over 60°C, and even exceed 80°C in some local areas for short periods. This high-temperature environment not only causes the overall temperature of the high-temperature protective shell 1 to rise, but also causes the water storage tank 2 to expand due to the heat generated by the water inside. If the tank is rigidly fixed, the stress generated by thermal expansion will have nowhere to be released, which can easily lead to weld cracking, loosening of connectors, or deformation of the tank, thereby compromising the seal and causing water leakage or steam leakage. The supporting circular plate 3, as a load-bearing transition component, has a diameter significantly larger than the outer diameter of the buffer damping rod 4. On the one hand, it increases the contact area with the bottom surface of the tank, evenly distributing local pressure and preventing metal fatigue; on the other hand, it provides sufficient space for the arrangement of the limiting structure below it. The buffer damping rod 4 is vertically installed below the center of the supporting circular plate 3, with its top end embedded in the mounting hole on the bottom surface of the supporting circular plate 3, and its bottom end firmly anchored to the bottom surface of the working groove 9, forming a stable vertical force transmission path.

[0034] Due to the difference in the coefficient of linear expansion of metallic materials at high temperatures, a relative displacement tendency inevitably occurs between the water storage tank 2 and the high-temperature protective shell 1. Without effective restraint, this displacement can easily lead to sealing failure at the wall penetration point of the water supply pipe 13, loosening of the filter plate 11 connection, or even collision and friction between the tank and the inner wall of the shell, resulting in abnormal noise or structural damage. To address this, limiting cylinders 5 are symmetrically arranged on both sides of each buffer damping rod 4, with their axes strictly parallel to the buffer damping rod 4, forming a coplanar guiding restraint unit. A limiting groove 6 is axially penetrated inside the limiting cylinder 5, and a pressure-bearing block 8 is slidably assembled in the groove. The height of the pressure-bearing block 8 is slightly less than the depth of the limiting groove 6, thereby maintaining a small gap in the vertical direction to accommodate height changes caused by thermal expansion, while forming a rigid limiting boundary in the horizontal direction.

[0035] Specifically, when the water storage tank 2 attempts to move laterally to one side due to thermal expansion or vibration, the supporting circular plate 3 shifts accordingly, causing the structure below it to move synchronously. At this time, the pressure block 8 on the side of the movement direction first contacts the inner wall of the limiting groove 6 and bears the thrust. The thrust is transmitted through the pressure block 8 to the wall of the limiting cylinder 5, and finally the limiting cylinder 5 transmits its reaction force to the bottom surface of the working groove 9, thereby effectively preventing the tank from continuing to move. Since the limiting cylinders 5 are symmetrically arranged on both sides of the buffer damping rod 4, no matter whether the tank shifts to the left or right, there is always a pressure block 8 on one side that can respond in time and provide a reverse constraint force, realizing bidirectional limiting.

[0036] In one embodiment, one end of the limiting rod 7 is vertically fixed to the center of the top surface of the pressure block 8, and the other end extends upward and is fixedly connected to both sides of the center of the bottom surface of the supporting circular plate 3. The limiting rod 7 is arranged parallel to the buffer damping rod 4.

[0037] The aperture of the primary filter screen 14 is larger than that of the secondary filter screen 15. The primary filter screen 14 is located inside the inlet of the water supply pipe 13 near the end of the water pump, and the secondary filter screen 15 is located inside the outlet of the water supply pipe 13 at the end of the water storage tank 2.

[0038] In a specific application of this utility model embodiment, in the fluid delivery path, the primary and secondary filter screens 15 installed inside the water delivery pipe 13 form a gradient filtration barrier. Their pore sizes and installation positions are matched to form a water purification logic of "coarse outside and fine inside, bidirectional protection". Specifically, the primary filter screen 14 near the inlet of the water pump adopts a larger pore size, mainly intercepting larger particulate impurities (such as rust chips, sealing ring fragments, or pipe deposits) generated by backflow from external pipelines or pump wear, preventing these coarse pollutants from directly impacting the valve core of the flow-limiting solenoid valve 16 or clogging the pump chamber; while the secondary filter screen 15 near the outlet of the water storage tank 2 adopts a finer pore structure to capture tiny suspended matter (such as fiber fragments, microbial film fragments, or calcium and magnesium precipitate particles) that cannot be completely intercepted by the primary filter plate 11 inside the water storage tank 2. This two-stage arrangement, from the outside in and from coarse to fine, not only extends the service life of each filter element and prevents premature clogging of a single high-precision filter, but also forms a redundant protection mechanism—even if the first-stage filter 14 fails due to maintenance negligence, the second-stage filter 15 can still provide basic protection, and vice versa.

[0039] Meanwhile, there is a profound coupling relationship between the structural stability ensured by the limiting rod 7 and the water cleanliness achieved by the dual-stage filter. If the water storage tank 2 shakes due to the failure of the limiting rod, it will not only cause alternating stress at the interface of the water supply pipe 13, accelerating the aging of the seal, but also disturb the water flow in the tank, causing impurities deposited at the bottom to be resuspended and flushed into the water supply pipe 13 with the water flow, increasing the load on the secondary filter 15, and even causing instantaneous blockage, triggering the malfunction of the flow limiting solenoid valve 16. Conversely, if the filtration structure is unreasonable, causing impurities to accumulate near the inlet of the water supply pipe 13, it will also change the local flow field, induce vortex-induced vibration, and indirectly aggravate the shaking of the tank.
