Scrubber Design and Functionality

The video tutorial explains scrubbers, devices that facilitate contact between liquid and particles to remove pollutants from the air. It covers various throat designs that influence pressure drop and discusses particle collection mechanisms like impaction, interception, and diffusion. The tutorial highlights factors affecting scrubber efficiency, such as pressure drop, liquid rate, and solid percentage in the recycled loop. It emphasizes the importance of precise design data for effective scrubber operation.

What is the primary function of a scrubber?

• To heat the air

• To cool the air

• To act as a liquid and particle contactor

• To filter out large debris

What is the main purpose of various throat designs in scrubbers?

• To increase the temperature

• To facilitate contact between gas, water droplets, and solid particles

• To reduce noise

• To enhance color

How do particles larger than 3 microns get collected in a scrubber?

• By floating

• By evaporating

• By dissolving

• By hitting water droplets due to their mass

What is the term used when particles between 1 to 3 microns are collected by falling within a half diameter of a water droplet?

• Absorption

• Diffusion

• Interception

• Impaction

What happens to very fine particles in a scrubber?

• They dissolve in water

• They settle at the bottom

• They behave like air molecules and collide with water droplets

• They evaporate

Which factor is NOT crucial for scrubber efficiency?

• Percentage of solid in the recycled loop

• Liquid rate

• Pressure drop

• Color of the scrubber

What can be adjusted to achieve the desired efficiency in a scrubber?

• Material, shape, and weight

• Noise level, speed, and height

• Temperature, color, and size

• Pressure drop, liquid rate, and percentage of solid in the recycled loop

What are the two types of solids mentioned in the recycled loop?

• Dissolved and undissolved

• Metallic and non-metallic

• Heavy and light

• Organic and inorganic

Why is precise design data important in scrubber design?

• To save money and ensure efficient operation

• To increase the noise level

• To reduce the size

• To enhance the color

What is a key difference between cyclone scrubbers and pulse jet filters?

• The color of the equipment

• The design data requirements

• The noise level

• The temperature range
