Green Engineering Spreadsheets: Section-2 Dust and Pollution Collection

John Andrew, P.E.

Course Outline

This 4 PDH online course defines the basic: equipment, applications, and design equations of industrial dust and pollution collection equipment including: fans, cyclone collectors, bag houses, and electrostatic precipitators.

Industrial dust collection applications include: Blasting – Carpet Manufacturing - Chemical Processing - Fiber Glass - Laser Cutting - Mining - Paper Manufacturing - Pharmaceutical - Rubber Grinding - Seed Processes - Solar Panel Fabrication - Thermal/Flame Spray - Welding - Woodworking.

Dust and pollution collection system parameters are analyzed using Excel spreadsheets.

This course is Section-2 of several, “Green Engineering” courses including: G321 Insulation, M237 Heat Transfer Excel Calculations, M236 Steam & Combustion Power Cycles Spreadsheet.
Topics include:
1. Industrial Fans
2. Cyclone Collectors
3. Bag House Collectors
4. Electrostatic precipitators
5. Conversion Factors

The course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

Learning Objective

At the conclusion of this course the student will:

• Have a spread sheet useful for dust and pollution collection calculations;
• Use "Goal Seek" to optimize equipment design;
• Calculate: Fan Air Volume Capacity, Pressure Head, and Power Laws;
• Determine circular equivalent of rectangular ducts;
• Find air friction loss in galvanized steel ducts with turbulent flow;
• Document design calculations in a spread sheet format;
• Convert common metric and U.S. units;
• Estimate cyclone collection efficiency;
• Read cyclone alone and with bag House collection efficiency graphs;
• Find the most efficient and cost effective types of dust collectors;
• Research fabric collectors used for dust particulate filtration;
• Find that for pulverized coal units, 60-80% of ash leaves with the flue gas;
• Study electrostatic precipitator collection applications;
• Estimate electrostatic precipitator collection efficiency; and

Intended Audience

The information will be especially useful to: facility managers, energy & environmental managers, industrial process engineers, mechanical engineers, and industrial plant managers, and all those involved with green engineering.

Benefit to Attendees

Attendee of this course will be able to calculate and optimize variables in a useful range of dust and pollution collection projects. Some advantages of spreadsheet calculations over hand written include:
2. better recall from archives.
3. greater accuracy.
4. faster with repeat use.
5. graphs are created automatically.
6. numerous useful formulas.
7. "Goal Seek" enables optimization.
8. solve any equation with, "Solver".
9. solve sets of linear and non-linear equations.
10. calculations and graphs may be pasted into documents and slide show presentations.

Course Introduction

Excel and other spread sheets are used to calculate and optimize dust collection equipment parameters.

Calculations have been done with a calculator and written by hand with pen or pencil. Optimizing design values with a calculator is difficult and time consuming. Quite often it is impossible to read and check these documents. As time passes these documents are lost or are difficult to read. It becomes more difficult to use these documents to make improvements to existing designs. Spread sheets can be stored indefinitely and accessed electronically.

Course Summary

This course provides Excel spread sheets to calculate a range of basic dust collection parameters. All variables can be adjusted to optimize design goals. Excel print-outs of design parameters and calculated results provide easy to read documentation for checking and future improvements.
