Description

Technical Field

[0001] This utility model relates to the field of descaling technology for water tower packing in power plants, and specifically to a descaling device for water tower packing in power plants. Background Technology

[0002] Cooling towers are the most commonly used cooling equipment in power plants, and the function of cooling tower packing is to increase the contact area between water and air, thereby improving evaporative cooling efficiency. However, during temperature changes and concentration processes, minerals such as calcium and magnesium ions in the circulating water will precipitate and form hard scale (mainly composed of calcium carbonate and calcium sulfate), which adheres to the surface of the packing. Existing descaling methods include physical cleaning or chemical cleaning. Physical cleaning includes high-pressure water jet rinsing and manual knocking and brushing.

[0003] In the above-mentioned physical cleaning, high-pressure water gun rinsing and manual knocking and brushing both require manual operation. Manual knocking and brushing even require disassembling the packing for cleaning, which is complicated and laborious. Therefore, we propose a descaling device for packing of power plant water towers. Utility Model Content

[0005] (II) Technical Solution To achieve the above objectives, the technical solution adopted by this utility model is as follows: A descaling device for cooling tower packing in a power plant includes a cooling tower body, a base fixedly installed at the bottom of the cooling tower body, and a water-air separator, a water distribution plate, and a packing assembly installed sequentially from top to bottom inside the cooling tower body. The packing assembly includes packing, with support members fixedly installed on both the upper and lower sides of the packing. Buffer members are symmetrically installed on the left and right sides of the bottom of the support members, and the support members are fixedly installed in the inner cavity of the cooling tower body through the buffer members. An ultrasonic transducer is fixedly installed on the top of the lower support member, and the ultrasonic transducer and the packing are arranged alternately. An ultrasonic generator is fixedly installed on the left side wall of the main body of the cooling tower, and the ultrasonic generator is connected to the ultrasonic transducer through a connecting line. In this process, ultrasonic energy is transmitted to each group of ultrasonic transducers via a connecting line through an ultrasonic generator. The high-frequency mechanical vibration generated by the ultrasonic transducers creates a "cavitation effect" in the water, generating tiny bubbles that burst instantly, producing a huge impact force that crushes and peels off the scale on the surface of the packing material.

[0006] Further defining the above technical solution, air inlets are provided on the left and right sides of the bottom of the circumferential sidewall of the cooling tower body, and an exhaust port is provided on the top of the cooling tower body. An exhaust fan is fixedly installed inside the exhaust port.

[0007] Further defining the above technical solution, a water collection cover is fixedly installed in the inner cavity of the base, and a cooling water drain pipe is connected to the bottom of the water collection cover, with the cooling water drain pipe extending out of the right side wall of the base.

[0008] Further defining the above technical solution, the top of the water distribution plate is connected to a cooling water inlet pipe, which is a metal pipe and extends out of the right side wall of the cooling tower body.

[0009] Further defining the above technical solution, the buffer component includes a support platform fixedly installed on the inner wall of the cooling tower body. A telescopic rod and a spring are fixedly installed on the top of the support platform. The spring is sleeved on the outside of the telescopic rod, and the tops of both the telescopic rod and the spring are fixedly connected to the bottom of the support component.

[0010] Further defining the above technical solution, the support is a rigid metal water pipe, and nozzles are fixedly installed at equal intervals at the bottom of the upper support, with the nozzles connected to the inner cavity of the support, and the nozzles and packing are arranged alternately.

[0011] Further defining the above technical solution, the top of the packing assembly is connected to a water inlet hammering mechanism, the top of the water inlet hammering mechanism is fixedly connected to a flushing water inlet pipe, and support beams are fixedly installed on both the upper and lower right sides of the water inlet hammering mechanism. The water inlet hammering mechanism is fixedly connected to the right side wall of the cooling tower body through the support beams. The inner cavity of the water inlet hammering mechanism is horizontally rotatably connected to a water turbine shaft, and water turbine blades are fixedly connected to the outer circumference of the water turbine shaft. The left side of the water turbine shaft extends to the left side wall of the water inlet hammering mechanism, and an eccentric hammering disc is fixedly installed on the left side of the water turbine shaft. The bottom of the water inlet hammering mechanism is fixedly connected to a flexible telescopic pipe, which is connected to the upper support component.

[0012] Further defining the above technical solution, the eccentric hammering disc can vibrate the upper support component when it rotates.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides a method with the following beneficial effects: The ultrasonic generator transmits ultrasonic energy to each group of ultrasonic transducers through connecting lines.

[0018] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0019] Example 1: This example provides a descaling device for power plant water tower packing, such as... Figure 1-2As shown, this solution addresses the problem that both high-pressure water jet washing and manual tapping and brushing require manual operation, which is complex and labor-intensive, often necessitating the removal and cleaning of packing materials. The solution includes a cooling tower body 1, with air inlets 101 on the left and right sides of the bottom of the circumferential sidewalls of the cooling tower body 2, and an exhaust outlet 102 on the top of the cooling tower body 1. An exhaust fan 103 is fixedly installed inside the exhaust outlet 102, and a base 2 is fixedly installed at the bottom of the cooling tower body 1. The inner cavity of the base 2 is fixed... A water collection cover 201 is installed, and a cooling water drain pipe 202 is connected to the bottom of the water collection cover 201. The cooling water drain pipe 202 extends out of the right side wall of the base 2. A water-air separator 3, a water distribution plate 4 and a packing assembly 5 are installed in the inner cavity of the cooling tower body 1 from top to bottom. A cooling water inlet pipe 401 is connected to the top of the water distribution plate 4. The cooling water inlet pipe 401 is a rigid metal pipe and extends out of the right side wall of the cooling tower body 1. The cooling water inlet pipe 401 is fixedly connected to the cooling tower body 1. The packing assembly 5 includes packing 501. Support members 502 are fixedly installed on both the upper and lower sides of the packing 501. Buffer members are symmetrically installed on the left and right sides of the bottom of the support members 502. The support members 502 are fixedly installed in the inner cavity of the cooling tower body 1 through the buffer members. An ultrasonic transducer 507 is fixedly installed on the top of the lower support member 502. The ultrasonic transducer 507 and the packing 501 are arranged alternately. An ultrasonic generator 7 is fixedly installed on the left side wall of the cooling tower body 1, and the ultrasonic generator 7 is connected to the ultrasonic transducer 507 through a connecting line. The ultrasonic transducer 507 is installed on the top of the lower support 502 through a probe, and the ultrasonic transducer 507 extends to the middle position of the packing 501 in the vertical direction through the probe. If there is enough funding and space, ultrasonic transducers 507 can be installed at different heights on the same probe, which can better achieve the descaling work. In this process, ultrasonic energy is transmitted to each group of ultrasonic transducers 507 via a connecting line through an ultrasonic generator 7. The high-frequency mechanical vibration generated by the ultrasonic transducer 507 creates a "cavitation effect" in the water, generating tiny bubbles that burst instantly, producing a huge impact force, thereby crushing and peeling off the scale on the surface of the filler 501.

[0020] Based on the above features, the working principle of this utility model is as follows: When a thermal power plant generates electricity, it needs to use cooling water. The cooling water has a high temperature after use and needs to be cooled down before reuse or discharge. This requires the use of a cooling water tower. The cooling water that needs to be cooled in the thermal power plant is transported to the water distribution plate 4 in the inner cavity of the cooling tower body 1 through the cooling water inlet pipe 401. Then, it is dispersed by the water distribution plate 4 and falls to the packing assembly 5 below. The packing assembly 5 then dissipates heat from the cooling water. During heat dissipation, the fan 103 in the exhaust port 102 works. External air enters the inner cavity of the cooling tower body 1 through the air inlet 101 and is finally discharged through the exhaust port 102. In this way, the cold air flows from bottom to top, and the cooling water to be cooled flows from top to bottom, which can better remove the heat from the cooling water.

[0021] During descaling, the ultrasonic generator 7 is activated, transmitting ultrasonic energy to each group of ultrasonic transducers 507 via connecting lines. Cooling water continuously falls, and the falling water comes into contact with the ultrasonic transducers 507. This generates high-frequency mechanical vibrations that create a "cavitation effect" in the water, producing tiny bubbles that burst instantly, generating a huge impact force. This crushes and peels off the scale on the surface of the packing 501. Because the space between the packing 501 is small, the generated tiny bubbles burst instantly, generating a huge impact force that removes the scale on the packing 501 on both sides. Combined with the falling cooling water, the scale is further carried away, thus achieving the descaling process.

[0022] Example 2: Figure 1-4 As shown, this embodiment is based on the above implementation, and the technical problem solved by this embodiment compared with the above embodiment 1 is: how to improve the descaling efficiency. The difference from the above embodiment is that: the buffer includes a support platform 503 fixedly installed on the inner cavity side wall of the cooling tower body 1. A telescopic rod 504 and a spring 505 are fixedly installed on the top of the support platform 503. The spring 505 is sleeved on the outside of the telescopic rod 504, and the tops of the telescopic rod 504 and the spring 505 are fixedly connected to the bottom of the support 502.

[0023] The support 502 is a rigid metal water pipe. Nozzles 506 are fixedly installed at equal intervals at the bottom of the upper support 502. The upper support 502 can support the packing 501 and guide water. The nozzles 506 are connected to the inner cavity of the support 502. The nozzles 502 and the packing 501 are arranged alternately.

[0024] The top of the packing assembly 5 is connected to a water inlet hammering mechanism 6. A flushing water inlet pipe 601 is fixedly connected to the top of the water inlet hammering mechanism 6. The flushing water inlet pipe 601 is also a rigid metal pipe and is fixedly connected to the cooling tower body 1. Thus, the flushing water inlet pipe 601 can also support the water inlet hammering mechanism 6. Support beams 602 are fixedly installed on both the upper and lower right sides of the water inlet hammering mechanism 6, and the water inlet hammering mechanism 6 is connected to the cooling tower body 1 via the support beams 602. The water tower body 1 has a fixed connection to the right side wall of the inner cavity. The inner cavity of the water inlet hammering mechanism 6 is horizontally rotatably connected to a water turbine shaft 603. A water turbine fan blade 604 is fixedly connected to the outer circumference of the water turbine shaft 603. The left side wall of the water inlet hammering mechanism 6 extends from the left side of the water turbine shaft 603. An eccentric hammering disc 605 is fixedly installed on the left side of the water turbine shaft 603. A flexible telescopic pipe 606 is fixedly connected to the bottom of the water inlet hammering mechanism 6. The flexible telescopic pipe 606 is connected to the upper support member 502.

[0025] When the eccentric hammering disc 605 rotates, it can vibrate the upper support 502.

[0026] Based on the above features, the working principle of this utility model is as follows: Flushing operation: The flushing inlet pipe 601 is connected to the municipal water supply via a water pipe. It is best to pressurize the water with a water pump. The pressurized water can have a faster flow rate. The municipal water is delivered to the water inlet hammering mechanism 6 through the flushing inlet pipe 601, and then to the upper support member 502 through the flexible telescopic pipe 606. The upper support member 502 is closed at both ends, and the water will be sprayed out through the nozzle 506 below it to flush the surface of the packing 501. It also increases the water volume between the two adjacent packing groups 501, and makes better contact with the ultrasonic transducer 507 to generate more high-impact bubbles, which can better remove scale from the surface of the packing 501 and improve the descaling efficiency.

[0027] Hammering operation: When high-pressure water passes through the water inlet hammering mechanism 6, it impacts the water turbine fan blades 604, causing the water turbine shaft 603 to drive the eccentric hammering disc 605 to rotate. This causes the eccentric hammering disc 605 to hammer the upper support member 502. The vibration is then transmitted to the packing material 501 on the lower side through the upper support member 502. The vibration helps the sludge to detach from the packing material 501 and fall down, achieving a better descaling effect.

[0028] During vibration, the eccentric hammering disc 605 pushes the upper support 502 downward, the support 502 pushes the spring 505 to retract, and the telescopic rod 504 also retracts. When the eccentric hammering disc 605 moves away from the upper support 502, under the rebound force of the spring 505, the support 502 drives the packing 501 to rise, thereby achieving vibration.

[0029] Due to its expansion and contraction characteristics, the flexible expansion tube 606 can ensure that water can be transported even when vibration occurs.

[0030] To ensure the service life of spring 505 and allow for regular inspection and maintenance, spring 505 can be made of highly corrosion-resistant materials. In its initial state, spring 505 has been compressed by components such as filler 501, but there is sufficient compression distance from its elastic stroke to meet the requirements of rapping work.

[0031] The eccentric hammering disc 605 is also made of soft rubber, which can better achieve the rapping work.

[0032] It should be noted that both the ultrasonic generator 7 and the ultrasonic transducer 507 were purchased (they can be selected and purchased as long as they meet the usage and maintenance costs of this application, and there is no specific limitation on their models). The ultrasonic generator 7 is connected to its matching connection line, and the ultrasonic generator 7 is connected to the power lines in the power plant through the connection line.

[0033] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
