Description

Technical Field

[0001] The invention relates to the technical field of cooling tower equipment, in particular to an atomizing spray system for a glass fiber reinforced plastic cooling tower. Background Art

[0002] In the process of chemical plants, a large amount of cooling water is needed to cool down equipment such as reactors and condensers. In order to ensure the smooth progress of the production process, it is necessary to discharge the waste heat generated by various industrial equipment and process flows. In order to efficiently remove the reaction heat or process heat and ensure the stability and safety of the production process, FRP cooling towers are often used.

[0003] FRP cooling tower uses water mist and air to exchange heat to achieve the purpose of rapid heat dissipation. FRP cooling tower has the advantages of corrosion resistance, high strength, light weight, small size, small footprint, beautiful and durable, and is easy to transport, install and maintain, so it is widely used.

[0004] When the FRP cooling tower is working, the ratio of the air mass flow rate to the water mass flow rate entering the cooling tower is an important parameter in the design and operation of the cooling tower. It directly affects the cooling efficiency and energy consumption of the cooling tower. Therefore, when designing the FRP cooling tower, an optimal steam-water ratio range will be used according to the conditions.

[0005] However, during the operation of the cooling tower, the atomizing nozzle may be blocked or damaged, which will greatly affect the uniformity and stability of the sprayed cooling water, reduce the efficiency of heat exchange between cooling water and air, and can only be repaired by shutting down the machine for maintenance, which greatly affects the operation of the cooling tower. At the same time, when used for a long time, the cooling water will continue to flow through the spray pipe, which will cause scaling of the spray pipe and the nozzle, resulting in blockage of the nozzle and turbulence of the water flow in the spray pipe, affecting the spraying effect.

[0006] In view of this, we propose an atomizing spray system for FRP cooling tower. Summary of the invention

[0007] The object of the present invention is to provide an atomizing spray system for a glass fiber reinforced plastic cooling tower, which solves the problems raised in the above-mentioned background technology.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] An atomizing spray system for a glass fiber reinforced plastic cooling tower comprises a tower body, a negative pressure mechanism is arranged on the tower body, a water balancing pipe is fixedly installed on the tower body, and a plurality of spray mechanisms are connected to the water balancing pipe for automatically adjusting the spraying amount of cooling water;

[0010] The spray mechanism comprises a spray pipe, an atomizing nozzle is fixedly connected to the spray pipe, and a sealing block is arranged in the spray pipe;

[0011] An anti-blocking mechanism is provided between the water balancing pipe and the atomizing nozzle to prevent the cooling water from generating scale.

[0012] Preferably, a water inlet is opened on one side of the spray pipe, a heat exchange plate is fixedly installed in the spray pipe, a partition is also fixedly installed in the spray pipe, a heat exchange cavity is formed between the heat exchange plate and the partition, and an inner cavity is set between the spray pipe and the heat exchange plate and the partition.

[0013] Preferably, a plurality of sealing tubes are fixedly mounted on the partition, a sliding cavity is provided through the sealing tube, a piston is slidably mounted in the sliding cavity, and a moving rod is fixedly connected to the bottom end of the piston.

[0014] Preferably, the moving rod is fixedly connected to the sealing block, and the sealing block is located inside the atomizing nozzle.

[0015] Preferably, an armature is fixedly installed in the piston, an electromagnet is fixedly installed on the heat exchange plate, and the armature and the electromagnet are adapted to each other.

[0016] Preferably, the anti-blocking mechanism comprises a micro-bubble generator, a plurality of micro-bubble nozzles are fixedly mounted on the micro-bubble generator, and the micro-bubble nozzles are fixedly connected to the water equalizing pipe.

[0017] Preferably, a Venturi tube is fixedly installed between the water balancing pipe and the spray pipe, and a plurality of flow balancing plates are fixedly installed in the atomizing nozzle.

[0018] Preferably, the negative pressure mechanism comprises an induced draft seat, the induced draft seat is fixedly connected to the top of the tower body, a mounting seat is fixedly installed in the induced draft seat, a motor is fixedly connected to the mounting seat, and an induced draft fan is fixedly connected to the output shaft of the motor.

[0019] Preferably, a plurality of water baffles are fixedly installed at the top position inside the tower body, and water-absorbing cotton threads are fixedly connected between the plurality of water baffles.

[0020] Preferably, the water equalizing pipe is fixedly connected to a water inlet pipe, the other end of the water inlet pipe is fixedly connected to a water pump, an air inlet is opened on the tower body, fillers are installed in the tower body, and a water collecting layer is arranged at the bottom end of the tower body.

[0021] By means of the above technical solution, the present invention provides an atomizing spray system for a glass fiber reinforced plastic cooling tower, which has at least the following beneficial effects:

[0022] (1) The present invention provides an anti-blocking mechanism so that microbubbles are injected into the cooling water before spraying. Under the action of the microbubbles, the cooling water will not produce scale in the spray pipe and the atomizing nozzle, and has a certain purification effect on impurities such as dust, which can avoid the blockage of the spray pipe and the atomizing nozzle, effectively improve the uniformity of spraying during atomization, the service life of the equipment, and reduce the frequency of maintenance. In addition, the cooling water containing microbubbles is more uniform during atomization spraying, which can effectively improve the efficiency of heat exchange.

[0023] (2) The present invention can selectively close atomizing nozzles at different positions and numbers by setting up a spray mechanism and atomizing nozzles. After the atomizing nozzles are closed, the spraying amount of other atomizing nozzles will automatically increase, thereby selectively closing the atomizing nozzles while ensuring that the spraying amount and spraying uniformity remain unchanged, so as to avoid the problem that when an atomizing nozzle is damaged, the overall spraying effect is affected, thereby causing the overall heat exchange efficiency to be reduced.

[0024] At the same time, the spraying amount of the atomizing nozzle can be automatically adjusted according to the temperature of the cooling water, so that the spraying amount can be adjusted according to the temperature within the range of the optimal steam-water ratio, thereby improving the efficiency of heat exchange and reducing water loss.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-Figure 7 , an atomizing spray system for a glass fiber reinforced plastic cooling tower, comprising a tower body 1, an air inlet 2 is provided at the bottom of the tower body 1, for air to enter the tower body 1 to participate in heat exchange, and at the same time, the air inlet 2 is arranged at an angle, which plays a certain role in preventing dust and pollutants from entering. A negative pressure mechanism 3 is provided at the top of the tower body 1, which is used to provide negative pressure in the tower body 1, so that air can enter through the air inlet 2, and continuously move upward and be discharged under the action of the negative pressure mechanism 3, so that the entire heat exchange process is carried out continuously and efficiently.

[0039] A water balancing pipe 6 is fixedly installed on the tower body 1, and the water balancing pipe 6 is connected to the water pump 4 through the water inlet pipe 5. The water pump 4 can pump cooling water into the water balancing pipe 6 for distribution. A spray mechanism 7 is arranged in the tower body 1, and the spray mechanism 7 is connected to an atomizing nozzle 8. The spray mechanism 7 cooperates with the atomizing nozzle 8 to atomize and spray the cooling water, and can automatically adjust the spraying amount of the cooling water within a certain range according to the temperature of the cooling water, and can selectively close part of the atomizing nozzle 8, so as to ensure that the uniformity of the atomizing spray and the spraying amount are always within the optimal steam-water ratio range.

[0040] Anti-blocking mechanisms 9 are provided on the atomizing nozzle 8 and the water equalizing pipe 6 for adding microbubbles to the cooling water. The microbubbles can effectively prevent the formation and deposition of scale and dust in the water through adsorption, seeding, flotation, redox reaction and the formation of a hydrophobic layer, making the spraying more uniform and stable, and at the same time can extend the service life of the equipment and reduce the number of maintenance times.

[0041] The tower body 1 is provided with fillers for increasing the heat exchange area of ​​water vapor, improving air flow, etc., so as to make the heat exchange efficiency of water vapor higher. The bottom of the tower body 1 is provided with a water collecting layer 10 for collecting water after heat exchange cooling, and finally discharging it through the outlet pipe for recycling.

[0042] See also Figure 2-Figure 3 The negative pressure mechanism 3 includes an air induction seat 31, which is fixedly mounted on the top of the tower body 1 and is a truncated cone structure with a small top and a large bottom. A mounting seat 33 is fixedly mounted on the top of the air induction seat 31, and a motor 34 is mounted on the mounting seat 33. An induced draft fan 32 is fixedly mounted on the output shaft of the motor 34. The motor 34 can drive the induced draft fan 32 to rotate, thereby generating a negative pressure airflow, sucking air out of the tower body 1, and discharging it through the top opening of the air induction seat 31. When the air passes through the tower body 1, it will exchange heat with the cooling water, thereby taking out the heat in the cooling water.

[0043] A plurality of water baffles 35 are fixedly installed near the top of the tower body 1. The plurality of water baffles 35 are distributed in an array. A plurality of absorbent cotton threads 36 are installed between the water baffles 35. The water baffles 35 are a folded line structure, so that the water baffles 35 and the absorbent cotton threads 36 can effectively prevent the cooling water from splashing inside the tower body 1 or being carried out of the cooling tower by the airflow, thereby improving the cooling efficiency of the cooling tower and reducing water loss.

[0044] See also Figure 4-Figure 6 The spray mechanism 7 includes a spray pipe 71, which is fixedly installed inside the tower body 1. A water inlet 72 is provided on one side of the spray pipe 71 for the entry of cooling water. A heat exchange plate 74 is fixedly installed inside the spray pipe 71, and a partition 75 is also fixedly installed inside the spray pipe 71. A heat exchange cavity 76 is formed between the heat exchange plate 74, the partition 75 and the inner wall of the spray pipe 71. The heat exchange cavity 76 is filled with gas, which has a large thermal expansion coefficient and is not easy to undergo physical and chemical reactions, such as carbon dioxide, nitrogen, etc.

[0045] The spray pipe 71 is provided with an inner cavity 73, and the entire inner cavity 73 is in a connected state, that is, the heat exchange plate 74 and the partition 75 do not partition the spray pipe 71. A plurality of sealing tubes 77 are fixedly installed on the partition 75, and a sliding cavity 78 is opened in the sealing tube 77. A piston 711 is slidably installed in the sliding cavity 78. A moving rod 79 is fixedly installed at the bottom end of the piston 711. A sealing block 710 is fixedly connected to the bottom end of the moving rod 79. The sealing block 710 is located inside the atomizing nozzle 8.

[0046] When the cooling water enters the inner cavity 73 through the water inlet 72, it will first contact the heat exchange plate 74, thereby transferring heat to the inside of the heat exchange cavity 76. Under the action of thermal expansion and contraction, it will drive the piston 711 to move along the sliding cavity 78, and the piston 711 will drive the moving rod 79 to move synchronously. The moving rod 79 will drive the sealing block 710 to move, thereby changing the position of the sealing block 710 in the atomizing nozzle 8. Since the sealing block 710 is a truncated cone structure, the gap between the sealing block 710 and the atomizing nozzle 8 will change, so that the spraying amount of cooling water will change according to the temperature of the cooling water.

[0047] An armature 712 is fixedly installed in the piston 711, and an electromagnet 713 is fixedly installed in the heat exchange chamber 76. The electromagnet 713 and the armature 712 are adapted to each other, so that by controlling whether the electromagnet 713 is energized, it is possible to choose whether to apply magnetic force to the armature 712. After power is turned on, the electromagnet 713 can drive the armature 712 to move, thereby driving the piston 711 to move, and the piston 711 drives the sealing block 710 to move until the atomizing nozzle 8 is completely blocked, thereby realizing the control of the opening and closing of the corresponding atomizing nozzle 8 by the electromagnet 713, so that a single atomizing nozzle 8 can be selectively closed, so that the number of working atomizing nozzles 8 can be reduced when the atomizing nozzle 8 is damaged, thereby ensuring the uniformity and stability of the atomizing nozzle 8 during spraying. At the same time, when the atomizing nozzle 8 is closed, the piston 711 is at the top of the sliding chamber 78, squeezing out the gas in the sliding chamber 78, causing the other pistons 711 to move downward, thereby increasing the spraying amount of the other atomizing nozzles 8, ensuring that the overall spraying amount and the flow rate of the cooling water will not change.

[0048] See also Figure 4-Figure 7 The anti-blocking mechanism 9 includes a microbubble generator 91, a microbubble nozzle 92 of the microbubble generator 91 is fixedly mounted on the water averaging pipe 6, and the water averaging pipe 6 is fixedly connected to the water inlet 72 of the spray pipe 71 through the venturi tube 93, so that the microbubbles generated by the microbubble generator 91 can enter the water averaging pipe 6 through the microbubble nozzle 92 to mix with the cooling water, and then enter the inner cavity 73 of the spray pipe 71 through the venturi tube 93. Since the venturi tube 93 is a contraction-type pipe, the mixture of microbubbles and cooling water will accelerate when passing through, so that the microbubbles can be more evenly mixed in the cooling water. At the same time, there are multiple microbubble nozzles 92, and they are respectively located at the connection between the venturi tube 93 and the water averaging pipe 6, so that the mixing of microbubbles and cooling water is more even.

[0049] A plurality of flow equalizing plates 94 are arranged in the atomizing nozzle 8, so that the cooling water mixed with microbubbles will be evenly flowed when passing through, so that the mixture of microbubbles and cooling water is mixed more evenly before being sprayed out by the atomizing nozzle 8, and no blockage or uneven spraying will occur when atomized and sprayed out by the atomizing nozzle 8. After being sprayed, the cooling water mixed with microbubbles will be sprayed more evenly than ordinary cooling water, so that the heat exchange efficiency between cooling water and air is higher.

[0050] It should be noted that, when in use, an atomizing spray system for a FRP cooling tower starts the water pump 4, which pumps cooling water into the water equalizing pipe 6 through the water inlet pipe 5, starts the microbubble generator 91, and the microbubbles are filled into the water equalizing pipe 6 through the microbubble nozzle 92 and mixed with the cooling water, and then pass through the Venturi tube 93 and then enter the inner cavity of the spray pipe 71 through the water inlet 72. Since the Venturi tube 93 is a contraction type pipe, the mixture of microbubbles and cooling water will accelerate when passing through, so that the microbubbles can be more evenly mixed in the cooling water.

[0051] The cooling water passes over the heat exchange plate 74, and exchanges heat through the heat exchange plate 74 and the heat exchange chamber 76. As a result, the volume of the gas in the heat exchange chamber 76 changes due to thermal expansion and contraction, thereby squeezing the piston 711 to move. The piston 711 moves along the sliding chamber 78, and the piston 711 drives the moving rod 79 to move synchronously. The moving rod 79 drives the sealing block 710 to move, thereby changing the position of the sealing block 710 in the atomizing nozzle 8. Since the sealing block 710 is a truncated cone structure, the gap between the sealing block 710 and the atomizing nozzle 8 changes, thereby changing the spraying amount of the cooling water according to the temperature of the cooling water.

[0052] When the mixture of microbubbles and cooling water passes through the atomizing nozzle 8, it will first pass through the flow equalizing plate 94 provided in the atomizing nozzle 8, so that the cooling water mixed with microbubbles is evenly flowed, so that the mixture of microbubbles and cooling water is mixed more evenly before being sprayed out by the atomizing nozzle 8, and no blockage or uneven spraying will occur when the mixture is atomized and sprayed out by the atomizing nozzle 8. After being sprayed, the cooling water mixed with microbubbles will be sprayed more evenly than ordinary cooling water, so that the heat exchange efficiency between the cooling water and the air is higher.

[0053] Start the motor 34, which drives the induced draft fan 32 to rotate, thereby generating negative pressure, so that air enters the tower body 1 from the air inlet 2 of the tower body 1 and is discharged through the opening on the induced draft seat 31. In the process of air flowing upward, it will first contact the filler, thereby improving air flow, making the air and water fully contact, and improving heat exchange efficiency. When the air contacts the cooling water, the heat in the cooling water will be exchanged out, and then discharged through the opening on the induced draft seat 31, which plays a cooling role.

[0054] When the air carrying water mist contacts the water baffle 35 and the water-absorbing cotton thread 36, the water baffle 35 and the water-absorbing cotton thread 36 will intercept the water mist carried in the air, thereby preventing the cooling tower from taking away a large amount of water during operation, resulting in the need to continuously replenish cooling water. The cooled water will fall into the water collection layer 10 along the filler and be recycled.

[0055] When the atomizing nozzle 8 is damaged or blocked, the electromagnet 713 can be started and energized to generate magnetism. The electromagnet 713 drives the armature 712 to move through the magnetic force, and the armature 712 drives the piston 711 to move. The piston 711 drives the sealing block 710 to move until the atomizing nozzle 8 is completely blocked, thereby realizing the opening and closing of the corresponding atomizing nozzle 8 controlled by the electromagnet 713, so that the damaged atomizing nozzle 8 and the atomizing nozzle 8 at the corresponding position in the array can be closed. When the atomizing nozzle 8 is closed, the piston 711 is at the top of the sliding cavity 78, and the gas in the sliding cavity 78 is squeezed out, so that other pistons 711 move downward, so that the spraying amount of other atomizing nozzles 8 is increased, ensuring that the overall spraying amount remains basically unchanged and the flow rate of the cooling water remains unchanged. Thereby, the atomizing nozzle 8 can be sprayed selectively while ensuring that the spraying amount and the uniformity of the spraying remain basically unchanged, so that the atomizing nozzle 8 can be selectively selected without stopping the machine, avoiding the problem of uneven spraying caused by damage or blockage of the atomizing nozzle 8 affecting the heat exchange efficiency, and troubleshooting can be carried out in time to avoid affecting the operation of the FRP cooling tower.
