Industrial Air Pollution Control

INTRODUCTION

What is Industrial Air Pollution?

“Airborne particulates, toxic and hazardous air pollutants that are known or suspected to cause health risks or adverse enviromental effects”.

Factory air pollution is often thought of as mostly smokestack emissions, but industry pollutes water and land as well. Once pollutants enter the atmosphere or the water system, they can spread far and wide beyond the factory. The most common factory air pollutants are greenhouse gases from the burning of fossil fuels. Factories contribute to water and land pollution by acidifying rain, chemical spills and disposal of toxic waste.

Choosing the right system for your company

Just about every industrial process generates airborne pollutants in the form of dry particles, fumes, vapors or mist. These contaminants are often toxic and lead to an unsafe work environment if not properly controlled. So, it is critical to select an air filtration system and manufacturer with the experience to solve your company’s specific air quality issues.

Cleaner factory air can provide many advantages including improved workplace safety and employee health, decreased housekeeping and maintenance costs, compliance with increasingly stringent OSHA and EPA standards and overall better product quality.

Mist / Fume collection

UAS’ Smog Hog® are the most effective electrostatic precipitators (ESP) on the market today. In fact, UAS was the first company to employ ESP technology to collect wet pollutants from industrial manufacturing processes. No other electrostatic unit on the market can match a Smog-Hog in efficiency, effectiveness and long-term cost savings for the collection of oil smoke and coolant mist.

Smog-Hog® mist collectors are available in variety of sizes and versatile configurations to fit your company’s needs. Depending on your applications, system can be ducted, hung from the ceiling, machine mounted, and portable and even installed outdoors.

HOW IT WORKS

How the Electrostatic Precipitation Technology (ESP) works?

The Smog-Hog is a two-stage electrostatic precipitator that effectively collects and cleans grease-laden air, smoke, and reduces odurs associated with restaurant cooking operations. The contaminated air first passes through a mechanical pre-filter which collects larger particles. This filtered air then passes through Smog-Hog’s uniquely-designed ionizer where the airborne particles are subjected to an intense electronic charge. These ionizer particles next enter the charged field of the collecting cells where ground plates strips the particles from the air stream. The collected grease agglomerates into larger droplets which drain into the sump.

The ESP Advantage

Electrostatic Precipitation Technology (ESP) is the key to the superior performance of the Smog Hog. Unlike bag or box filters that remove only the largest particles, Smog Hog electrically charges even microscopic contaminants, and then captures them magnetically in an aluminum collection cell. As a result, this sophisticated electronic solution leaves virtually no grease or hazardous particle untouched, releasing only clean air from the system. UAS’s ESP technology ensures constant airflow, unlike barrier filters that can plug and become ineffective.

PROBLEM SOLVING

Fume Extraction

Plastic Fumes – When plastic materials are processed, there is often a plasticizer contaminant that is emitted. This can happen during extrusion due to coatings or residuals left on a die or mold. They are generally submicron smoke contaminants that are tacky or sticky. These emissions are harmful to workers who can breathe in the hazardous particles during operation of the machine if the smoke is not properly captured and controlled.

Mist Elimination

Metalworking Mist and Smoke – When coolants and lubricants are applied to machining processes, the generated force and heat creates mist and smoke. The type of contaminant depends on what coolants are being used and the machining parameters. Water-soluble coolants produce a mist with larger droplet sizes where straight oils produce more of a smoke that can be submicron in size. Higher speed machines or processes that generate a large amount of heat will produce higher concentrations of contaminants.

Dust Removal

Dry Machining Dusts – Dry machining will produce contaminants from the material being machined and the process heat. The contaminant will generally be a mix of larger particles from the displaced material and finer dust particles from the machining process. The properties of the material being cut, type of machining process, cutting rate, and the hours of operation affect the contaminant generation rates and contaminant size.
