Coupling, wrapping agglomeration device for ultra fine particles in sound field of gaseous and solid jet flow

Abstract

The invention belongs to a gas-solid ultrafine grain removing technology field, involves a gas-solid jet flow - sound field ultrafine grain coupling to wrap the reunion equipment, it is suitable for pellet reunions that the particle size is smaller than 3 micron but bigger than 5 microns pellets, the main body includes the gas importation, the enlargement section, the reunion room, the jet pipe, the shrinkage pipe, the reduction section export and four levels of speakers. The enlargement section has a smooth enlargement type importation, the jet pipe is installed in the back-end of the enlargement section, fixes in the reunion room through locknuts, the length of the jet pipe in the reunion room can be adjusted by the locknuts; the primary speaker fixes in the ultrafine grain reunion room on one side of the jet pipe, and the third-level strengthened type speaker is installed in turn behind primary speaker; the gas reduction section outlet has a smooth change-over portion structure, which avoids the turbulent flow which is produced in the reducing section to produce to the pellet gathering group's stave, compared with the existing technology, it has a wide operation region, reliable operation, and the pellet gathers the group to control keenly and so on.

Description

Technical field: [0001] The invention belongs to the technical field of removal of gas-solid ultrafine particles, and relates to a gas-solid jet-acoustic field ultrafine particle coupling packaging and agglomeration device, which is especially suitable for particles with a particle diameter of less than 3 microns to be reunited under the coupling action of the jet flow and the sound field to a size larger than Device for 5 micron particle agglomerates. Background technique: [0002] At present, a large number of ultrafine inhalable particles are produced in the production process of large coal-fired power plants, waste incinerators and petroleum refining industries, and cyclone dust collectors, electrostatic precipitators and bag dust collectors are generally used to solve these ultrafine inhalable particles and other equipment to capture particles with a particle size of less than 3 μm, but the capture efficiency of these existing equipment and technologies is only 50-60%, ...

AI Technical Summary

Problems solved by technology

Ultrafine particles can also be agglomerated by using a high-energy-density sound field, but when the particle size distribution of the ultrafine particles has a quasi-uniform distribution, the sound field cannot make the ultrafine particles form particle agglomerations, which shows the effect of a single sound field on the agglomeration of ultrafine respirable particles limitations
