Salt aerosol drying and blending device

Abstract

The invention discloses a salt aerosol drying and blending device which comprises a heating cavity, a wet fog cavity, a fixed seat, a uniform mixing cavity and a secondary filtering chamber, the heating cavity and the secondary filtering chamber are respectively fixed on the fixed seat; the wet fog cavity and the uniform mixing cavity are respectively connected with the heating cavity; the wet fogcavity is fixed in the heating cavity; the wet fog cavity and the heating cavity are respectively communicated with the uniform mixing cavity; the wet fog cavity is provided with a wet fog diffusionconical opening; the uniform mixing cavity is provided with a wet fog diffusion conical head, the wet fog diffusion conical opening and the wet fog diffusion conical head are matched to form a conicalcavity, the flow direction of hot air entering the uniform mixing cavity from the heating cavity and the flow direction of wet fog entering the uniform mixing cavity from the wet fog cavity form tangential flow, and aerosol generated in the uniform mixing cavity is filtered by the secondary filtering chamber. The device can be used in cooperation with various saline aerosol generators, generatedparticulate aerosol is dried more sufficiently, the concentration is more stable, two-stage screening can be achieved, particle size distribution is more single, the overall structure is simple, and cleaning and maintenance are convenient.

Description

technical field [0001] The invention belongs to the technical field of aerosol generators, in particular to a saline aerosol drying mixer. Background technique [0002] Aerosol is a colloidal dispersion system formed by dispersing solid or liquid small particles and suspending them in a gas medium, also known as a gas dispersion system. Its dispersed phase is solid or liquid small particles with a size of 0.001-100 microns, and its dispersion medium is gas. Aerosols are widely used in medicine, environmental science, and military science. People prepare aerosols through corresponding preparation methods and devices according to different purposes. [0003] At present, in the production and testing of filter materials such as masks and melt-blown cloth, saline (NACL) aerosol particles are used to detect the filtration efficiency of filter materials. In the saline aerosol generator, the core components include dry mixers. At present, domestic salt Most of the dry mixers used...
