Multi-pulse blowing type sound wave combined deashing method

Abstract

The invention provides a multi-pulse blowing type sound wave combined deashing method, which is characterized by including the steps: setting a multi-pulse blowing type sound wave combined deashing device, leading a sound wave sounding diaphragm of the device to generate sound waves under the action of pulse air flow at the initial moment, and under the second working condition, performing sound wave deashing and pulse blowing deashing simultaneously by the device, so that the pulse air flow in an inner pipe of a blowing pipe realizes combined efficient deashing in the attenuation gas atmosphere by the aid of a diaphragm sounder. By the aid of the method, venturi tubes are omitted, filtering bags with filtering mouths at the height approximate to 20mm-300mm can also be used for effectively deashing, limitation of inner dead angles of the filtering bags can be broken through, and more efficient deashing can be realized.

Description

technical field [0001] The invention relates to a multi-pulse injection type acoustic wave combined dust removal method. Background technique [0002] The sonic cleaning method is to turn the compressed air into a strong sound wave with a certain energy through the sound wave generator and feed it into the bag room space of the dust collector for omnidirectional propagation. Since the intensity and frequency of the sound waves are designed according to the requirements of dust removal, the sound waves are converted into mechanical energy after reaching the filter bag of the dust collector, and form high-speed periodic oscillations with the dust to offset the accumulation force (surface adhesion) of the dust in the airflow to prevent The dust combines with each other to form a crust. At the same time, the sound wave can also loosen the agglomerated dust, so that the dust can easily fall off from the filter bag, so that the sound wave can remove the dust layer of the filter b...

Problems solved by technology

[0003] Although sonic cleaning has its advantages, it is used as an auxiliary device in the application, and it is rarely used alone.

However, if a combined device is used for dust removal, not only there are more components, the structure is more complicated, and the effective space of the equipment is occupied, but also the workload and operating cost of equipment maintenance are increased.
