Abstract

The invention relates to an aerosol distribution device which comprises an aerosol generator. The aerosol generator is communicated with a gas inlet system, an aerosol inlet system and an aerosol gas output system separately. The gas inlet system is used for providing gas of certain pressure and flow for the aerosol generator. The aerosol inlet system is used for providing a certain amount of powdery and granular aerosol for the aerosol generator. The aerosol generator is used for mixing received gas and the aerosol into aerosol gas of the certain concentration, and then, the aerosol gas is conveyed to an experimental loop main pipeline through the aerosol gas output system. According to the aerosol distribution device, gas is used as an aerosol carrier, an aerosol material is uniformly, stably and efficiently conveyed into the experimental loop main pipeline within a long period of time, and it is ensured that aerosol distribution can simulate actual possible working conditions; and the aerosol distribution device is simple and compact in structure and convenient to install and has the high adjustability.

Description

technical field [0001] The invention belongs to a solid particle material distribution device, in particular to an aerosol distribution device. Background technique [0002] After a serious accident, the pressurized water reactor nuclear power plant may be over-pressurized, which will cause damage to the integrity of the containment, and a large amount of radioactive material leaks, which will lead to threats to the environment and personnel. To this end, the PWR nuclear power plant has set up a containment filtration and discharge system to filter and discharge the atmosphere of the containment after a serious accident to ensure that the pressure of the containment does not exceed the design value, thereby ensuring the integrity of the containment. Filter the exhaust gas to prevent the radioactivity of the exhaust gas from exceeding the emission limit. The main components of the containment atmosphere after a serious accident are radioactive aerosols. In order to measure t...
