Engineering nanoscale particle aerosol generating system and working method thereof

Abstract

The invention belongs to the field of aerosol generation, and provides an engineering nanoscale particle aerosol generation system and a working method thereof. The engineering nanoscale particle aerosol generation system comprises an air compressor, a condenser, a filter, an atomizer, a multi-stage diffusion dryer and a charge neutralizer which are sequentially connected in series, the atomizer is further connected with a nano-particle solution generating device, and the atomizer is used for mixing the air flow purified by the filter and the nano-particles generated by the nano-particle solution generating device, atomizing the mixture and uniformly sending the mixture to the multi-stage diffusion dryer; air flow purified by the filter is directly introduced into the charge neutralizer,the charge neutralizer is used for neutralizing the nano-particle mixed air flow dried by the multi-stage diffusion dryer and forming nano-scale particle aerosol, and the purified air flow is used forspraying the nano-scale particle aerosol into a body cavity for storage; and the body cavity is connected with a negative pressure pump, and the negative pressure pump is used for pumping redundant nanoscale particle aerosol to maintain the pressure of the body cavity so as to improve the disinfection and sterilization effect.

Description

technical field [0001] The invention belongs to the field of aerosol generation, and in particular relates to an engineering nanoscale particle aerosol generation system and a working method thereof. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

Problems solved by technology

[0004] The inventors found that the aerosol particles generated by the existing engineering nano-particle aerosol generation system are relatively large in size and poor in filtering effect, resulting in a lot of aerosol impurities; the aerosol is injected into the body cavity with the airflow, and the pressure in the body cavity As the gas continues to enter, it will increase, which will affect the bearing capacity of the body cavity on the one hand, and affect the aerosol concentration in the body cavity on the other hand, thereby reducing the disinfection and sterilization effect of the aerosol in the body cavity
