Strong sound agglomeration device and method for treating suspended particles

Abstract

The invention provides a strong sound agglomeration device and a strong sound agglomeration method for treating suspended particles. The strong sound agglomeration device comprises a strong sound source assembly, an agglomeration cabin assembly and a conventional dust removal assembly, wherein the agglomeration cabin assembly comprises a cylindrical head cabin, a cone transition cabin, a bidirectional modal standing wave tube for forming axial and radial standing wave fields and a cylindrical tail cabin, the cylindrical head cabin is connected to the strong sound source assembly and is provided with an opening for inputting gas to be treated, the major diameter end of the cone transition cabin is connected to the cylindrical head cabin, one end of the bidirectional modal standing wave tube is connected to the minor diameter end of the cone transition cabin, and the other end of the bidirectional modal standing wave tube is connected to the cylindrical tail cabin. The method comprises the following steps: step one, starting the strong sound source assembly, so that strong sound waves simultaneously form the axial and radial high strong sound standing wave fields in the bidirectional modal standing wave tube; step two, inputting the gas to be treated into the agglomeration cabin assembly, and aggregating the suspended particles into agglomerates with large particle sizes under the effects of the axial and radial high strong sound standing wave fields in the bidirectional modal standing wave tube; and step three, removing the agglomerates with large particle sizes in airflow by using the conventional dust removal assembly.

Description

technical field [0001] The invention relates to a technology for removing suspended particles, in particular to a strong-acoustic agglomeration device and method for processing suspended particles. Background technique [0002] With the rapid development of my country's economy, the amount of inhalable particulate matter (PM10) emitted into the atmosphere from human-made sources is increasing day by day, among which fine particulate matter (PM2. Large, not only seriously endanger human health, but also affect the climate and atmospheric visibility. In recent years, the atmospheric environment monitoring data of various provinces and cities have shown that PM2.5 exceeding the standard has occurred from time to time, and the situation of exceeding the standard is serious in some areas. Facts show that PM2.5 has become the main air pollutant in my country's cities. PM2.5 is mainly produced by man-made sources, including stationary sources and mobile sources. Stationary sources...
