Built-in distributed full three-dimensional continuous micro-flow high-energy sound wave high-efficiency and energy-saving cleaning system

Abstract

The invention discloses a built-in distributed full-stereo continuous micro-flow high-energy sound wave high-efficiency and energy-saving dust cleaning system, which includes a resonator-type sonic cleaner, a pulse-resonance composite sonic cleaner, a pulse-type sonic cleaner and a compressed gas pipeline. Distributed full stereo wave ash cleaning unit composed of distributed full stereo wave ash cleaning unit; distributed full stereo wave ash cleaning unit is installed at intervals on the compressed gas pipeline; The air port, the air inlet of the pulse resonant cavity composite acoustic soot cleaner and the air inlet of the pulse type sonic soot cleaner are in fluid communication with the compressed gas pipeline respectively; the compressed gas pipeline is laid along the flow direction of the flue gas in the flue. Pulse-type sonic cleaning, resonant-cavity sonic-cleaning, and pulse-resonant-cavity composite sonic-cleaning work together to perform sonic soot cleaning, which can remove ash, scaling and coking on the inner wall of the flue.

Description

technical field [0001] The invention relates to the technical field of flue dust cleaning. Specifically, it is a built-in distributed full-stereo continuous micro-flow high-energy sound wave high-efficiency and energy-saving dust cleaning system. Background technique [0002] Ash accumulation, fouling or coking on the inner wall of the boiler flue in a power plant will lead to an increase in the temperature of the exhaust gas, which will not only cause energy waste, but also affect the safe operation of the boiler. Due to the characteristics of no dead angle arrival in sonic cleaning, it gradually began to replace the traditional sootblower. The principle of sonic cleaning is to radiate sound waves to the inner wall of the flue that has accumulated dust, scale or coke. Under the action of sound waves, the dust, scale or coke will fall off the inner wall of the flue due to fatigue caused by sound. In the prior art, the external structure of installing the sonic soot cleaner...

AI Technical Summary

Problems solved by technology

In the prior art, the external structure of installing the sonic soot cleaner on the inner wall of the flue is mostly used, and the sonic soot cleaner of a single structure is used, and the sound intensity remains unchanged; while the sonic soot cleaner required for dust accumulation, scaling or coking The intensity and frequency are different, and because the structural environment of the inner wall of the flue is not exactly the same, it is difficult for the existing single form of sonic cleaner to completely remove the ash, scaling or coking on the inner wall of the flue
