How to buy Industrial Air Pollution Control Equipment?

Industrial emissions today are considered to be the primary source of respiratory diseases. Ambient air pollution control or curbing industrial air pollution is a matter of serious concern to the communities in the vicinity. In cities, rapid construction activities, poor waste management, vehicular emissions & industrial sources are together responsible for deteriorating air quality. Emissions such as nitrogen oxides, and hydrocarbons lead to the formation of toxic smog and acid rain that causes respiratory problems leading to serious lung illnesses, and ozone depletion, contributing to global warming. In the present industrial economic era, air pollution is an inescapable by-product that cannot only be eradicated from the source but rigorous and consistent actions such as regular air quality monitoring and deploying air pollution control equipment can lead to a significant pollutant reduction. 

With this increasingly important context in place, we provide you a comprehensive background to the sources of pollution & globally emerging solutions for point source control of air pollution & solutions to ambient air pollution.

Sources of emissions in Industries: 

Point-Source Emissions:

also known as the stationary sources of emission, are released at height or ground level, from an identifiable source, and are dispersed in the atmosphere. Emissions from stationary sources. It is easy to trace the source of such emissions back to stacks, outlets, etc.  

Non-Point Source:

 A source of emission that is not easily identifiable. These are called mobile and fugitive emissions, they consist of leaks of particulate matter from transportation and loading, for example, are not identifiable and stationary sources. Also called diffuse or ‘fugitive emissions’ (non-point sources), are contrary to stack emissions and originate from an area, such as a stockpile or a road.

Types of Air Pollution Control Technologies Deployed in Heavy Industries:

Heavy industry processes involve both indoor and ambient air pollution. Fugitive emissions are a form of pollution that is not easily captured by air pollution control devices. To mitigate air pollution in heavy industries, the only effective solution is pollution control equipment designed to address ambient air pollution in larger areas. Certain technologies only cater to specific pollutants in particular stages of the processes but that does not help in the mitigation of air pollution considering the larger picture. 

Here is a list of the top industrial air pollution control equipment to buy: 

  1. Point Source air pollution control technologies
  2. Ambient air pollution control technologies.

Point Source Air Pollution Control Technologies:

  • Scrubbers:

SCRUBBER

Scrubbers or Wet Scrubbers are devices that trap suspended particles through direct contact with the spray of liquid. Due to countless tiny droplets, the particulates collide and are washed away from the dirty airstream. There are several configurations of wet scrubbers in use namely; spray-tower scrubbers, orifice scrubbers, and venturi scrubbers. The efficiency of the scrubber depends upon the relative velocity between the droplets and the particulates.

  • Electrostatic Precipitators:

ESP

 

Electrostatic precipitators are a widely used method to eradicate particulates from airstreams. In an electrostatic precipitator, as the particulates enter the unit, they get laden with electric charge and are then removed by the influence of an electric field. The charged particles are then attracted to collector plates carrying the opposite charge.  The effectiveness of electrostatic precipitators in removing fly ash from the combustion gases of fossil-fuel furnaces accounts for their high frequency of use at power stations.

  • Baghouse Filters:

Baghouse

Baghouse filters are a collection of fabric-filter bags that remove suspended particulates from the air stream. A baghouse consists of an array of long, narrow bags of about 25 cm (10 inches) in diameter each. These are suspended upside down in a large enclosure. Dust-laden air is blown upward through the bottom of the enclosure by fans. Particulates are trapped inside the filter bags, while the clean air passes through the fabric and exiting from the top of the baghouse. This method offers relatively high resistance to airflow, which leads to substantial energy usage for the fan system.

Latest Ambient Air Pollution Control Technology:

  • Pulsed Radio Wave Based Air Cleaners:

Pulsed radio wave air cleaners use pulsed radio waves in the WIFI spectrum to accelerate the natural clearance of particulate pollutants such as PM10 and PM2.5 in the air. This technology helps mitigate ambient air pollution without passing air through several filters before delivering clean air into the enclosed spaces. These air cleaners come with the advantage of zero maintenance. Only annual routine maintenance of air quality monitors is required. 

Pros and Cons of Current Air Pollution Control Technologies Deployed:

Most air purifiers use a filter for dust removal, and the process of passing air through multiple chambers is both laborious and costly since filters and other equipment have to be changed regularly, whether for industrial use or domestic purposes. This also causes a constraint on the amount of air that can be filtered at any point. This is a limitation for most commercial air purification systems.

Here are a few pros and cons of commercial air purifiers:

Technologies: Pros: Cons: 
Baghouse Filters Highly effective in PM Collection Not well suited for high dust load and require heavy maintenance
Electrostatic Precipitators High pollutant collection efficiency. High initial capital cost. Cannot control gaseous emissions.
Wet Scrubbers Provide gas absorption and dust collection in one unit Expensive sludge removal

Introduction & Comparison of Modern Air Pollution Control Technologies:

Yes, we hear you. There are a ton of air filters for industrial use out there, We compared the top industrial air pollution control equipment to buy.  The comparison shows how the latest ambient air pollution control technology stands out among various point source control technologies. 

What makes Pure Skies any different? 

Here’s how Pure Skies is different from any of the commercial air purification systems:

Comp1

 

It’s been Four years since Pure Skies was launched by Devic Earth, and it’s set to become even better with Pure Skies 2.0, the most hassle-free and effective answer to ambient air pollution.

Pure Skies by Devic Earth:

Pure_Skies (1)

Pure Skies, a product of a decade of research, is based on pulsed radio wave air pollution control technology that addresses large areas, cleaning ambient air pollution including fugitive emissions. Pure Skies reduces air pollution by removing pollutants such as PM2.5, and PM10 from the air.

The Technology: Pure Skies is a flagship technology that uses pulsed radio waves to be spread across the area to be covered, via base stations and extender units of Pure Skies. This operates in the normal Wi-Fi signal range and is completely safe. Our unique technology arrests particulate matter, PM2.5, and PM10 in the air making them heavy and sink to the ground. Pure Skies only accelerates the natural process of dry deposition, whereby minute particles of dust settle in the ground.

Pure Skies is an excellent choice for industries such as cement, iron and steel, thermal power plant, mining, smelters, automobile, sugar, shipping and ports, auto ancillary components, and cities.

Use Cases of the latest tech in ambient air pollution control:

Pure Skies was installed at one of India’s leading minerals processing plants to mitigate the problem of high, often unaccounted emissions. Despite having in place pollution control systems, the plant still faced high emissions of pollutants, and associated risks such as opposition from neighboring communities, and also administrative roadblocks in terms of closing the plant and/or being charged heavy fines. 

Within four weeks of installation, Pure Skies 

  1. Reduced PM2.5 levels by 66%
  2. Reduced PM10 levels by 55%

 

The plant benefitted from the immense drop in pollution levels and enjoyed the security and enhanced performance enabled by Pure Skies.
