Description

Technical Field

[0001] This utility model belongs to the field of aerosol technology, specifically relating to an aerosol sedimentation performance evaluation device. Background Technology

[0002] Aerosols are stable colloidal systems formed by the dispersion of small-sized liquid or solid particles in air. The size of the particles is generally described by their aerodynamic diameter; in aerosol systems, the aerodynamic diameter of dispersed liquid or solid particles ranges from 1 to 10⁵ nm. Aerosols have a wide range of sources, broadly categorized into anthropogenic and natural pollution sources.

[0003] Radioactive aerosols refer to aerosols containing particulate matter that possesses a certain degree of radioactivity or that has been contaminated by external radioactive nuclides, thus acquiring radioactivity. Radioactive aerosols not only share the characteristics of ordinary aerosols but also possess the properties of radioactive nuclides themselves, and can enter the human body through ingestion, respiration, and other activities, causing further damage. Therefore, efficient purification technologies for radioactive aerosols are of great significance to human health.

[0004] Currently, there is no specialized equipment for testing the sedimentation performance of aerosols. Laboratories typically conduct experiments using simple sealed chambers made of acrylic sheets. However, this structure is simple and the volume of the chamber cannot be adjusted, resulting in poor experimental results. Utility Model Content

It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example:

[0025] An aerosol sedimentation performance evaluation device, comprising:

[0026] Box 1 is a rectangular transparent glass box, allowing a clear view of the internal cavity 15. To further improve the stability of the device, steel plates can be added to the edges of each glass panel of box 1, and then connected by welding or other means to further enhance the safety of the device. Wheels 2 are fixedly installed at the bottom of box 1.

[0027] A smoke-generating nozzle 9 is provided on one side of the housing 1. The smoke-generating nozzle 9 has a cylindrical structure and can be directly snapped into the hole on the side wall of the housing 1. In use, the smoke generator can be directly aimed at the smoke-generating nozzle 9 to generate smoke, and the smoke-generating pipe can be connected to the smoke-generating nozzle 9.

[0028] The other two sides of the housing 1 are equipped with a particle size analyzer 4 and an operating cylinder 3.

[0029] The probe 13 of the particle size analyzer 4 is fixedly mounted on the fixing plate 10, which in turn is fixedly mounted on the side wall of the housing 1. The probe 13 is located inside the housing 1 to detect the aerosol concentration. The display part of the particle size analyzer 4 is located on the outside, which allows for convenient display and operation.

[0030] The operating cylinder 3 is fixedly installed on the side of the box 1, and rubber is bonded to it. You can put your hand into the rubber without directly contacting the internal material to complete the operation.

[0031] An ion generator is installed on the front of the housing 1. The ion generator includes a duct fan 5, a negative ion generating module 6, a duct fan speed controller 7, and a negative ion generator switch 8, which are connected in sequence. The duct fan 5 is fixedly installed on the front of the housing 1, with its front end located inside the housing 1. The parameters of the negative ion generator are shown in Table 1 below.

[0032] Table 1 Parameters of Negative Ion Generator

[0033]

[0034] The back of the housing 1 is provided with a hinged door 11, which is equipped with a handle to close and lock the door 11.

[0035] Threaded holes 16 are provided on the vertical glass plates at the four corners inside the housing 1, and positioning screws 17 are installed in the threaded holes 16. When a certain volume needs to be set according to experimental requirements, the adjusting plate 14 inside the housing 1 is moved to a suitable position, and the positioning screws 17 below it are tightened to support the adjusting plate 14. This allows for adjustment of the space size.

[0036] Usage and Principles:

[0037] During use, the smoke generator is directly aimed at the smoke nozzle 9 to generate smoke, and the probe 13 of the particle size analyzer 4 detects the aerosol concentration in the inner cavity 15 of the housing 1. After spraying to a certain concentration, a solvent for purifying the aerosol is then sprayed in, and the purification effect is tested over a certain period of time.

[0038] In addition, while spraying the solvent to purify the aerosol, the negative ion generator switch 8 is turned on. The two work together to test the aerosol purification effect, thereby evaluating the aerosol settling performance.
