Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a thermal power plant boiler with an acoustic wave ash cleaner. Background Art

[0002] A thermal power plant is a plant that uses combustibles as fuel to produce electricity. After long-term use, a large amount of coal ash will adhere to the boiler inside the thermal power plant, and it is often necessary to use an ultrasonic ash cleaner to blow away the ash inside the boiler.

[0003] For example, a Chinese patent with publication number CN211551577U discloses a thermal power plant boiler with an acoustic wave ash cleaner, including a combustion furnace, the top of which is fixedly connected with a feed port, ..., and the outer surface of which is fixedly connected with an air intake pipe. The thermal power plant boiler with an acoustic wave ash cleaner avoids the problems of coal accumulation and incomplete combustion by setting a first filter plate, a second filter plate and a third filter plate, thereby improving the utilization rate of energy. Air is blown into the combustion furnace through the air intake pipe, so that there is sufficient oxygen in the combustion furnace to assist combustion, ensuring that the coal can be fully burned, reducing the generation of carbon monoxide, avoiding the problem of excessively high carbon monoxide content in the surrounding environment, which leads to poisoning of personnel, and improving environmental protection.

[0004] In the above patent, multiple filter plates are set up and the energy of sound waves is utilized to convert the surface of coal into ash. The falling of ash reduces the volume of coal, and the reduced coal is burned through multiple filter plates to improve energy utilization. However, during operation, the ash cleaning pipe inside the boiler wall becomes loose and falls off due to the vibration of sound waves, which has certain limitations. In addition, after the ash cleaning pipe is vibrated, a gap may be generated between it and the boiler wall, affecting the sealing effect.

[0005] Therefore, we propose a thermal power plant boiler with an acoustic wave ash cleaner to solve the above-mentioned problems. Utility Model Content
