Sonic ash remover capable of realizing airflow cutting based on cam movement

Abstract

The invention discloses a sonic ash remover capable of realizing airflow cutting based on cam movement. The sonic ash remover comprises a mechanical case and an air chamber, wherein the air chamber is a sound production device of the ash remover; a loudspeaker is connected to one side of an air outlet outside the air chamber, and high-pressure air from an air compressor is connected to one side of an air inlet; the air inlet is communicated with the air outlet through an air passage; a cam is arranged in the mechanical case, and is driven by a driving device to rotate; a guide wheel tangential to the outer circle of the cam is further arranged in the mechanical case, and is connected with a connecting rod through an elastic device; the other end of the connecting rod is connected with a covering piece which reciprocally moves up and down under the action of the connecting rod; high-pressure airflow in the air passage flows out from the outlet side of the air chamber at high speed in a pulsing manner to form sonic waves.

Description

Technical field [0001] The invention discloses a sound wave ash remover which realizes air cutting based on cam movement. Background technique [0002] With the sustained and rapid development of my country's economy, the electricity consumption in society is also continuously increasing. The boilers of domestic thermal power plants in my country mainly use coal as the combustion section, and various boiler equipment will be produced by the combustion of coal during the operation process. A large number of tiny dust particles, these tiny dust will accumulate and grow on the surface of each heat exchanger in the furnace and flue, resulting in ash accumulation and slagging in the furnace. However, China’s power coal is of poor quality, with high ash content and high sulfur content. Generally, the types of coal used in power station boilers are changeable. At the same time, the combustion of coal and the heat exchange between flue gas and medium are extremely important. A complex ph...

Problems solved by technology

However, this kind of soot remover still faces many problems. For example, when the "chosen flute" sonic soot blower is in the working gap, the ash in the boiler furnace is poured into the blower through the horn, so that the modulation turntable of the sonic soot blower is blocked. serious, resulting in severe friction between the modulation disc and the chamber wall of the generator, and finally causing the motor that drives the modulation disc to fail to start due to excessive torque, and then burns the motor

It poses a serious threat to the safety and stability of the control mechanism of the entire sootblower
