Abstract

The invention discloses a sound source device for sound wave agglomeration, which can generate a sound source for sound wave agglomeration and is mainly applied to dust removal, demisting, smoke removal and other scenes. The device comprises a connecting pipeline, a horn cover, a nozzle, a central connecting rod and a resonance cavity, the connecting pipeline is arranged in the center of the horncover, the first end of the connecting pipeline is located outside the horn cover, and the second end is located in the horn cover and provided with a plurality of vent holes in the circumferential side. The nozzle is mounted at the second end of the connecting pipeline; the first end of the central connecting rod extends into the nozzle and is fixedly connected with the second end of the connecting pipeline, and a convex part is arranged at the first end of the central connecting rod and forms a slit with the nozzle; the resonance cavity is installed at the second end of the central connecting rod. Acoustic waves with high sound pressure levels are generated, under the action of a flow field of the acoustic waves with the high sound pressure levels, tiny particles (pm10 or below) in the air can move relatively, wherein agglomeration is generated due to mutual collision between the particles, so that large particles are formed, and rapid deposition is achieved.

Description

technical field [0001] The invention relates to environmental protection equipment such as dust removal, mist removal and smoke removal, and in particular to a sound source device for sound wave reunion. Background technique [0002] In recent years, with the continuous development of my country's industry, energy consumption is increasing, and environmental problems are becoming more and more serious. Smog has appeared in most cities in my country, and the frequency and scope of occurrence are increasing, seriously affecting people's life and health. For the fine particulate matter PM2.5 in the atmosphere, it can be suspended in the air for a long time, and the higher its concentration in the air, the more serious the air pollution. Compared with coarser atmospheric particles, PM2.5 has small particle size, large area, strong activity, easy to attach toxic and harmful substances, and has a long residence time in the atmosphere and a long transportation distance, so it is h...
