Description

Technical Field

[0001] The utility model belongs to the technical field of nondestructive testing, and particularly relates to an electrostatic precipitator cleaning robot used for cleaning electrostatic precipitators in thermal power plants. Background Art

[0002] The boiler of a thermal power plant relies on coal combustion to produce qualified steam to drive the steam turbine unit to generate electricity. During the combustion process, a large amount of dust and harmful gases will inevitably be produced, causing environmental pollution and health hazards. As the country strengthens its efforts in environmental protection, the smoke emission concentration standard continues to decrease. The normal and efficient operation of electrostatic precipitator equipment is a key factor in meeting emission standards. The electrostatic precipitator relies on gas ionization. After the dust particles are charged, they move to the dust collecting plate under the action of the electric field force. Under the action of a reasonable vibration cycle and vibration force, the dust collected on the dust collecting plate falls into the ash collecting hopper in the form of flakes for removal. Electrostatic precipitators have been widely used for their high dust removal efficiency, low equipment resistance, strong ability to adapt to flue gas changes, and low maintenance workload.

[0003] However, in practice, due to poor operation, maintenance, and management, many electrostatic precipitators cannot realize their potential, have low dust removal efficiency, and fail to achieve the designed effect. Due to the complex internal structure of the electrostatic precipitator, its daily maintenance and inspection requires personnel to enter the narrow gap between the anode plate and the cathode wire, with a minimum spacing of only 200mm, which is extremely inconvenient and makes it impossible to ensure the quality of inspection. In addition, the internal environment is dusty, hot, and lacks light, which has a great impact on the health and psychological state of the inspectors.

[0004] Therefore, we hope to use robots instead of manual labor to inspect and clean the inside of the electrostatic precipitator, which not only avoids high-risk operations but also improves the efficiency and comprehensiveness of maintenance. Summary of the invention

[0005] In order to overcome the deficiencies in the above-mentioned prior art, the utility model provides an electrostatic precipitator cleaning robot that can move inside the electrostatic precipitator, carry out the integrity of the anode plate and cathode wire, the firmness of the welding point, and the spacing measurement of the anode plate. The electrostatic precipitator cleaning robot is equipped with adaptive lighting, which can realize the shooting of high-definition images in a high-dust environment. The camera has a zoom function, and the details are clearly presented. Defects and faults can be identified in a dark environment. Remote control operation and real-time wireless transmission of video data can be realized. The operator can even work outside the electrostatic precipitator. The controller has video data storage and playback functions. The electrostatic precipitator cleaning robot has a fast moving speed of up to 5 meters / minute, and supports continuous and long-term cruise detection. The electrostatic precipitator cleaning robot can be used to realize a comprehensive inspection before maintenance, diagnose the real situation inside the electrostatic precipitator, and provide targeted and accurate guidance and direction for the maintenance of the electrostatic precipitator. It can also conduct a comprehensive review after maintenance, conduct a comprehensive verification of the maintenance quality of the electrostatic precipitator, and ensure the quality after maintenance. The electrostatic precipitator cleaning robot is used for internal fault inspection and cleaning of the electrostatic precipitator, replacing manual labor with machines, reducing personal safety risks, improving the quality and efficiency of electrostatic precipitator maintenance, ensuring the good operation of the electrostatic precipitator, reducing smoke emissions, improving emission performance, and improving the operating stability of the unit.
