Description

Technical Field

[0001] The invention belongs to the technical field of sonic soot blowers, and in particular relates to a sonic soot blower for a flue gas cooler in a thermal power plant. Background Art

[0002] The sonic soot blower technology converts compressed air (or steam) into high-power sound waves or infrasound waves (a pressure wave that propagates in a spatial medium (gas) in the form of a sparse-density wave) and sends it into the furnace. When the accumulated ash on the heated surface is repeatedly pulled and compressed by the sparse-density waves that alternate at a certain frequency, it loosens and falls off due to fatigue and is carried away by the flue gas flow, or sinks to the ash hopper and is discharged under the action of gravity.

[0003] The prior art has the following problems:

The flue gas cooler has a large differential pressure during operation, and the heating surface of the internal tube bundle is blocked by dust accumulation, which reduces the heat exchange efficiency, increases the flue gas flow resistance, and increases the power consumption of the fan;

[0005] 2. It is convenient to adjust the position of the sonic soot blower, but it is difficult to quickly locate and install it, which affects the efficiency of the equipment and increases the installation cost. Summary of the invention
