Sound wave reinforced fine particle removing device and removing method thereof

Abstract

The invention discloses a sound wave reinforced fine particle removing device and a removing method thereof. The device comprises an aerosol turbulence and sound wave pretreatment area, an aerosol turbulence and sound wave agglomeration area, an aerosol dust collection area and an inertial sedimentation area which are sequentially communicated from top to bottom; the aerosol turbulence and sound wave pretreatment area and the aerosol turbulence and sound wave agglomeration area adopt a cyclone-like cutter structure with tangential air inlet; the aerosol turbulence and acoustic wave pretreatment area and the aerosol turbulence and acoustic wave agglomeration area adopt a counter-clockwise symmetrical air inlet mode; and the aerosol dust collection area and the inertial sedimentation dust collection area adopt cylindrical structures, and a cylinder wall adopts a water film dust collection plate structure. Aiming at aerosol particles discharged by a fixed source, the invention adopts a vertical integrated cylindrical structure form, realizes the efficient coagulation and removal of the aerosol particles, particularly fine particles, by a cooperative removal method combining a centrifugal separation technology, a sound wave agglomeration technology and an inertial sedimentation mechanism, and effectively avoids secondary dust raising, dust deposition and corrosion of a dust collection plate.

Description

technical field [0001] The invention relates to a particle dust removal device, in particular to a sound wave enhanced fine particle removal device and removal method. Background technique [0002] my country is a country that uses coal as its main energy source. While coal combustion provides us with heat and power, it also brings serious particle pollution. Among the sources of fine particles, emissions from coal-fired boilers account for a large part, especially It is a small and medium-sized industrial boiler and industrial kiln widely used in various industries. Due to the lack of corresponding environmental protection control equipment, the pollution is particularly serious. Aerosol particulate matter, especially fine particulate matter PM2.5, will seriously affect people's daily life and work after being discharged into the air, and even threaten people's life safety. Due to the small size and light weight of fine particles, they stay in the atmosphere for a long time...

Problems solved by technology

However, these agglomeration methods have certain disadvantages when they act alone, and the agglomeration effect on fine particles is not very obvious, so the final removal efficiency of fine particles cannot be effectively improved
