ESP for fine particle penetration

In summary, the conversation discusses a gas stream with particles of three sizes (10 micron, 7 micron, and 3 micron) and a particle density of 0.33333. The gas passes through an ESP that follows the Dutch-Anderson equation for penetration, where p=exp^(-Aw/Q). The overall penetration is 0.05, and the individual percent penetrations for each size can be found using the velocities of 0.33m/s for 10 micron, 0.23m/s for 7 micron, and 0.1m/s for 3 micron.

a gas stream has particles of three sizes, 10 micron, 7 micron and 3 micron. The particle density is the same for all three sizes as well as the weight concentration (0.33333). This gas passes through an ESP that obeys Dutch-Anderson equation arranged for the penetration:

p=exp^(-Aw/Q) where p is the penetration, A the collection area, Q the volumetric flow and w the drift velocity.

If the overall penetration is 0.05 What are the individual percent penetrations for each of the three sizes?

I'm really lost in the approach...

i just found the 3 velocities so far: 10 micron → 0.33m/s 7micron→ 0.23m/s 3micron→ 0.1m/s
 

1. What is ESP for fine particle penetration?

ESP stands for "electrostatic precipitator" and it is a technology used to remove fine particles, such as dust and smoke, from the air. It works by using an electric charge to attract and collect the particles onto plates or filters.

2. How does ESP for fine particle penetration work?

ESP works by first passing the air through an ionization section, where particles become electrically charged. The charged particles are then attracted to oppositely charged plates or filters, where they stick and are removed from the air stream. The clean air then passes through and is released back into the environment.

3. What are the benefits of using ESP for fine particle penetration?

ESP is a highly efficient and cost-effective method for removing fine particles from the air. It can remove up to 99% of particles from the air, making it a valuable tool for improving indoor and outdoor air quality. Additionally, ESP does not require the use of chemicals, making it an environmentally friendly option.

4. Are there any limitations to using ESP for fine particle penetration?

ESP may not be as effective in removing very small particles (less than 1 micrometer) or particles with a high electrical resistivity. It also requires regular maintenance and cleaning to ensure optimal performance. Additionally, ESP may not be suitable for all industries or applications, as it may not meet certain emission standards.

5. How does ESP for fine particle penetration compare to other air filtration methods?

Compared to other air filtration methods, ESP is typically more efficient and cost-effective. It also does not produce any harmful byproducts, making it a safer option. However, it may not be suitable for removing certain types of pollutants, such as gases or volatile organic compounds, which may require the use of other filtration methods.
