Abstract

The invention discloses a magnetic field offset particulate matter collecting device and method, and belongs to the technical field of collecting equipment. The device comprises a rack; an electrolyte tank; the air inlet formed in one end of the rack; an atomizing chamber of which the one end is communicated with the air inlet; an atomizing nozzle which is fixed on the inner wall of the atomizing chamber, is communicated with the electrolyte tank and is used for atomizing and spraying the electrolyte; a gas flow channel of which one end is communicated with the other end of the atomizing chamber, and is provided with an exhaust fan for sucking air in from the air inlet; a collecting chamber and a collecting channel. The side wall of the collecting chamber is communicated with the other end of the gas flow channel, and an electrified surrounding coil is wound outside the side wall of the collecting chamber; and the collecting channel communicates with the bottom of the collecting chamber, and a heating unit is arranged at the bottom of the collecting channel and used for heating the bottom of the collecting channel. According to the invention, aerosol particles and an atomized electrolyte solution are fully contacted and electrified by using the characteristic that aerosol is easy to adhere and electrified, and falling and collecting of the electrified aerosol particles are accelerated by using magnetic field deviation, so that the aerosol particles are rapidly and efficiently collected.

Description

technical field [0001] The invention belongs to the technical field of collection equipment, and more specifically relates to a magnetic field offset particle collection device and collection method. Background technique [0002] The exhaust gas produced by the catering industry and industry contains a large amount of aerosol particles. Aerosol particles refer to suspended, stranded and settled material particles in the atmosphere, called atmospheric particles, atmospheric particles, or suspended particles. In addition, some people refer to It is called "atmospheric aerosol", and the analysis and research of harmful particles in it is still an important topic at present. [0003] At present, the commonly used enrichment methods for containing aerosol particles include solution absorption method, packed column retention method, filter material retention method and other methods for enrichment treatment, but the effect is not obvious. [0004] After retrieval, Chinese Patent ...
