Embodiment 1

[0038] A two-stage cloud water collector based on impingement and cyclone cutting, the structure is as follows: figure 1 As shown, it includes an impact sampling head 1 and a cyclone cutting sampling head 4 that are detachably connected together and communicated with each other. The impact sampling head 1 includes a collection head 7 and an impactor. The bottom of the collection head 7 is provided with a nozzle 2, and the collection head 7 includes a collection head housing and a collection pipe located in the collection head housing. The collection pipe communicates with the nozzle 2. The impactor includes an impact section 8 and an air outlet pipe 9. The impact section 8 and the air outlet pipe 9 are integrally formed and connected. 8 is distributed with 3 impingement tubes 10 connected up and down. The nozzle 2 is inserted into the impact section 8 and is sealedly connected with the impact section. On the side wall of the air outlet pipe 9, there is a large particle size dro...

Abstract

The invention relates to a two-stage cloud water collector and collection method based on impact and cyclone cutting. The two-stage cloud water collector comprises an impact sampling head and a cyclone cutting sampling head, wherein the impact sampling head comprises a collecting head and an impactor, a nozzle is arranged at the bottom of the collecting head, the impactor comprises an impact section and an air outlet pipe which are integrally formed and are connected and communicated with each other, a plurality of impact pipes are distributed in the impact section, the nozzle is inserted intothe impact section and is in sealing connection with the impact section, a large-particle-size droplet storage pipe extending outwards is arranged on the side wall of the air outlet pipe and is connected to a large-particle-size droplet storage bottle, and the bottom of the air outlet pipe is connected and communicated with the cyclone cutting sampling head. The collector can effectively collectfine particles and simultaneously collect droplets of large and small two-stage particle sizes to realize separation and simultaneous sampling of cloud and atmosphere, thereby eliminating the influence of dissolved gaseous pollutants on a cloud water sample, and achieving the purpose of two-stage sampling of gaseous pollutants.

Description

technical field [0001] The invention relates to a two-stage cloud and mist water collector and collection method based on impact and cyclone cutting, belonging to the technical field of environmental protection equipment. Background technique [0002] Cloud and fog is a complex system composed of the atmosphere, cloud condensation nuclei (aerosol), liquid or solid water, usually refers to a weather phenomenon when small water droplets or small ice crystals are suspended in the atmosphere and reduce the horizontal visibility to below 1 km. When the relative humidity of the air is greater than 100% and the temperature drops suddenly, the water vapor in the air is easy to condense into small water droplets or condense into small ice crystals, resulting in clouds and fog. With the advancement of urbanization and the rapid development of industry in our country, the massive emission and secondary transformation of pollutants from man-made sources (such as industrial production, m...
