Description

Technical Field

[0001] This utility model belongs to the field of evaporative coolers and relates to an online dust removal device for evaporative coolers. Background Technology

[0002] The high-temperature flue gas in the evaporative cooler is cooled, coarsely dusted, and conditioned using a dual-media spray gun, creating conditions for fine dust removal by the subsequent electrostatic precipitator. When the high-temperature flue gas encounters the atomized water sprayed by the spray gun, the viscosity and humidity are high. Some of the ash adheres to the leeward side of the evaporative cooler wall along with the flue gas flow. Without any cleaning device, and under the influence of high temperature, it gradually forms ash blocks of a certain thickness and hardness, reducing the cross-sectional area of ​​the flue gas flow. This causes a large amount of flue gas to overflow from the converter mouth, forcing a shutdown for manual cleaning.

[0003] For the problem of ash accumulation in evaporative coolers, the traditional solution is to first optimize the water supply process control model of the evaporative cooler and optimize the evaporative cold spray gun. This solution is suitable for furnace conditions where the production process does not change much and the flue gas volume changes steadily. This solution was tried in the early stage, but the improvement effect was not obvious. The second solution is to recalculate the system parameters according to the changes in the production process to see if they are suitable for the current operating conditions, and modify the size of the evaporative cooler, such as increasing the height of the straight section or increasing the diameter, and simultaneously modify the dust removal pipeline or electrostatic precipitator. This solution involves a huge amount of engineering work, which is costly and time-consuming. Utility Model Content

[0004] To overcome the deficiencies in the aforementioned related technologies, this utility model proposes an online dust removal device for evaporative coolers. The online dust removal device for evaporative coolers includes: an evaporative cooler, vibration motors, and ultrasonic generators. Multiple vibration motors are sequentially fixed to the outer wall of the evaporative cooler from top to bottom, and the vibration motors are configured to drive the outer wall of the evaporative cooler to vibrate at low frequency. Multiple ultrasonic generators are sequentially fixed to the outer wall of the evaporative cooler from top to bottom, and the ultrasonic generators are configured to drive the outer wall of the evaporative cooler to vibrate ultrasonically.

[0005] Preferably, the online dust removal device for the evaporative cooler includes a support base and a motor base. The support base is a plate conforming to the shape of the outer wall of the evaporative cooler, and the support base is fixedly connected to the outer wall of the evaporative cooler. One end of the motor base is fixedly connected to the support base, and the structure of the other end of the motor base is adapted to the vibration motor, and the other end of the motor base is fixedly connected to the vibration motor.

[0006] Preferably, the outer diameter of the evaporative cooler is 3000mm to 6000mm. At least four vibration motors are fixed to the evaporative cooler from top to bottom. At least two ultrasonic generators are fixed to the upper and middle parts of the evaporative cooler.

[0007] Preferably, the lower part of the evaporator cooler is a conical tube structure, and three of the at least four vibration motors are evenly arranged downwards from the upper 1 / 3 of the evaporator cooler. One of the at least four vibration motors is fixed to the side wall of the conical tube at the lower part of the evaporator cooler.

[0008] Preferably, at least one ultrasonic generator is fixed on the outer wall of the evaporator above the at least four vibrating motors. At least one ultrasonic generator is fixed on the outer wall of the middle part of the evaporator.

[0009] Preferably, the vibration motor outputs an excitation force of 24kN and has a power of 1kW.

[0010] Preferably, the ultrasonic generator outputs a vibration frequency of 33-35.6Hz, and the vibration motor has a power of 0.75KW.

[0011] The beneficial effects of this utility model are as follows:

[0012] This invention can send sound waves with sufficient intensity and energy into various areas of the evaporative cooler that may accumulate dust or become caked. Through the action of sound energy, the flue gas molecules and dust particles in these areas will vibrate, preventing dust particles from accumulating on the barrel wall and achieving online real-time dust removal, thereby delaying the accumulation of dust.

[0013] This invention features convenient installation and maintenance, simple control operation, all-around ash removal without dead corners, and no environmental pollution. The acoustic ash removal technology not only eliminates accumulated ash and improves and maintains high heat exchange efficiency of the heat exchange surface, but also, due to the effect of sound waves, allows the flue gas to fully contact the atomized water droplets from the evaporative cooler spray gun. This fully evaporates the atomized water droplets and increases the contact with particulate matter, thereby improving the cooling and dust removal efficiency of the evaporative cooler.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] like Figure 1 and Figure 2 As shown, the utility model proposes an online dust removal device for an evaporative cooler 1. The online dust removal device for the evaporative cooler 1 includes: an evaporative cooler 1, a vibration motor 2, and an ultrasonic generator 3. Multiple vibration motors 2 are sequentially fixed to the outer wall of the evaporative cooler 1 from top to bottom, and the vibration motors 2 are configured to drive the outer wall of the evaporative cooler 1 to vibrate at low frequency. Multiple ultrasonic generators 3 are sequentially fixed to the outer wall of the evaporative cooler 1 from top to bottom, and the ultrasonic generators 3 are configured to drive the outer wall of the evaporative cooler 1 to vibrate ultrasonically.

[0021] The online dust removal device for the evaporative cooler 1 includes a support base 4 and a motor base 5. The support base 4 is a plate conforming to the shape of the outer wall of the evaporative cooler 1, and the support base 4 is fixedly connected to the outer wall of the evaporative cooler 1. One end of the motor base 5 is fixedly connected to the support base 4, and the structure of the other end of the motor base 5 is adapted to the vibration motor 2, and the other end of the motor base 5 is fixedly connected to the vibration motor 2.

[0022] The outer diameter of the evaporative cooler 1 is 3000mm to 6000mm. For example, it can be 3000mm, 4000mm, 5000mm, or 6000mm. Taking an evaporative cooler 1 with an outer diameter of 4500mm and a height of 20m as an example, eight vibration motors 2 are fixed sequentially from top to bottom on the evaporative cooler 1. Every two vibration motors 2 are at the same height, and the two vibration motors 2 at the same height are arranged opposite each other about the evaporative cooler 1. At least two ultrasonic generators 3 are fixed at the upper and middle parts of the evaporative cooler 1.

[0023] The lower part of the evaporator cooler 1 is a conical tube structure. Three of the at least four vibration motors 2 are evenly arranged downwards from the upper 1 / 3 of the evaporator cooler 1. One of the at least four vibration motors 2 is fixed to the side wall of the conical tube at the lower part of the evaporator cooler 1.

[0024] At least one ultrasonic generator 3 is fixed on the outer wall of the evaporator 1 above the at least four vibrating motors 2. At least one ultrasonic generator 3 is fixed on the outer wall of the middle part of the evaporator 1.

[0026] The ultrasonic generator 3 outputs a vibration frequency of 33-35.6Hz, and the vibration motor has a power of 0.75KW.

[0027] The ultrasonic generator 3 is interlocked with the converter oxygen valve signal. That is, when the converter oxygen valve is open, the ultrasonic generator 3 operates, and when the converter oxygen valve is closed, the ultrasonic generator 3 stops working.

[0028] The operation process of this utility model is as follows:

[0029] During the converter shutdown interval, the evaporator cooler 1 stops operating. At this time, the vibration motor 2 can be manually started to force vibration of the outer wall of the evaporator cooler 1 for about 1 minute. This vibration should be done twice per shift (8 hours per shift). However, the vibration motor 2 also has its drawbacks. The weld seams of the outer wall of the evaporator cooler 1 and the manhole may develop fatigue cracks under long-term vibration, resulting in poor system sealing. Subsequently, the operation can be adjusted in real time according to the ash accumulation inside the evaporator cooler 1 to reduce adverse effects and ensure the best ash removal effect.

Therefore, the protection scope of this utility model should be determined by the scope of the claims.
