Since the collected particles cannot be captured by the collecting unit 6 and have a relatively high amount of electric power, in order to make the experimental result unaffected by the particle charging effect, the airborne particles passing through the dust collector are first passed through the neutralization benefit 14 (Απι241) After neutralizing the electrical properties of the microparticles, the airborne microparticles I/Bei were then carried out. [Men, under the same set conditions, the test of the shellfish rate defined below was carried out four times, and the average value was taken as the experimental result. . From the difference between the concentration of the upstream and downstream aerosol particles of the electrostatic precipitator, the transmittance of different particle size intervals and set conditions can be known. The penetration rate is defined as follows: cin where P: electrostatic dust collector particle penetration Rate, which characterizes the efficiency of collecting particles: the concentration of particles upstream of the electrostatic precipitator, such as the concentration of particles downstream of the electrostatic precipitator. Hereinafter, the device used in the present invention will be described in detail: 1. Charged droplet generating portion 2: The nanoparticle generating device used in the present invention is a microinjection pump and an electrospray atomizer, which can generate 1 〇 nm. Particles up to 50 nm have geometric deviations of approximately L1 to 1β25. 2. Quantitative Output Atomizer (Model 200836838 3075, TSI Inc., St. Paul, MN, U, SA,) 10: Gas used to produce polydisperse in the submicron particle size range Hanging particles. The principle is that the high-pressure air is injected through a micro hole having a diameter of 〇·343 mm and is emitted at a high speed. According to the Bernumulli principle, the air pressure in the high-speed zone is low, so that the liquid is sucked into the low-pressure zone, by the foregoing The idle air column breaks up the liquid into tiny droplets. Due to the design relationship, the tiny droplets can leave with a 9-degree turn. • The atomizer 〇, the larger droplets are intercepted by the inertial impact and flow into the reservoir. The recommended air pressure is 35 psi. This pressure can be adjusted as needed. The number of droplets produced has a number median diameter of about 0.3 μπι' and a geometric standard deviation of less than 1.9. The size of the particle size is mainly determined by adjusting the volume fraction of the non-volatile solutes in the solution. 3. Neutralizer 14 (Am241) · Am-241 is a radioactive material with a true half-life of 432 years. The principle of charging particles with particles is to dissociate the air molecules into positive particles by using the particles released during the decay process. After the negative ions, these ions are attached to the surface of the charged particles to achieve the purpose of neutralization. 4.

Electrostatic Separation 11 200836838 The instrument uses the difference in the mobility of the particles to distinguish the particle size of the particles. The principle of the condensation tuber counter is to let the particles pass through a positive The alcohol-saturated vapor tube is mixed with saturated n-butanol vapor at 37t. The mixed gas is passed through a tube at a temperature of 10 ° C to condense n-butanol on the surface of the particle, and the particle grows to a detectable range. The number of particles can be known by using a photodetector. The range of CPC detection particle concentration is 1 (Γ2~1〇5 particles/cm3, and the measured particle size range is 5~1000 nm. _ It is clear that the present invention provides a charged droplet particle collection system that utilizes a charged droplet generating portion to generate a plurality of charged droplets that cause the charged droplets to adsorb particles in the air.
