Dry media and scrubbers or wet collectors are two distinct technologies designed to collect dust produced during production processes. Syntech shares that both kinds of dust collectors come with their pros and cons.
Wet Dust Collectors
Wet dust collection involves the use of centrifugal kind or cyclonic scrubbers or Venture scrubbers that function on different standards compared to dry cartridge collectors. Scrubbers collect dust by combining with water droplets. The scrubber becomes more efficient as the droplets get smaller.
The design of this equipment may integrate one or more of the methods to gather dust. This includes wet impingement configurations, spray nozzles, cyclonic action, Venturi dispersion and misters. As soon as it is collected, both dust and water drip into the settling tank where gravity separates them or where it skims dust from the surface.
For instance, dust-filled air goes into the scrubber indirectly and centrifugal forces then thrust the material to the outer wall, similar to how a cyclone works. The captured material then rests at the bottom of the sludge tank.
Dry Dust Collection
The National Fire Protection Association (NFPA) describes dust collectors as media and cyclone collectors, cartridge collectors and baghouses. Cartridge dust collectors are highly efficient, and these dry media kind of collectors are broadly used for the fine material dust produced in processing applications.
When dusty air goes in the collector, filter media captures it. Intermittent gusts of compressed air then remove the dust from the filters and transfer them into the hopper. Afterward, the dust is dislodged from the hopper before it moves into a detached container or storage drum that users must regularly empty. This prevents the dust from going back into the hopper.
Now that you are aware of the differences between wet and dry collectors, and their pros and cons, you can decide which is suitable for you.
We all understand that dust collection is beneficial in many ways. It minimizes pollution and the cleanup needed after the production process. Dust is also often combustible, so clearing the area of it reduces the risk of fires breaking out. Most of all, it protects industrial workers from inhaling potentially dangerous substances as they work.
The use of dust collection and downdraft booths prevents the dust from becoming a pollutant in the environment. Factories use them for a wide range of applications, including the collection of food dust such as candy, flour, and spices.
Though we all understand the risks of dust pollution to people, we rarely think of what their effect might be on the smallest creatures in the world: insects. Even food dust, which may seem relatively harmless, can negatively affect insect life.
Bees Are at Greater Risk
Many insects are negatively affected by air pollutants such as dust. Bees are especially susceptible to air pollution, as these sensitive animals rely on their environment to survive. One of the most obvious concerns is their ability to produce honey – humans rely on bees for their honey, which is a major food source for many cultures.
A few years ago, bee farmers in France reported that their bees were producing blue and brown colored honey. After some investigation, they found that bees had stopped collecting nectar from flowers and were collecting the remains of M&M shells from a nearby candy processing factory instead.
The story sparked an intense debate over the effects of pollution on insect life, especially on bees.
A Decline in Insect Population
The presence of dust in the environment becomes air pollution – lightweight dust can travel for miles in the wind and affect the insect populations. There is proof that it can lead to a sharp decline in insect populations, as some of the dust is toxic to insects.
The presence of dust can also affect insects’ ability to forage. Bees, for example, become confused and have a harder time finding flowers when there is too much dust in the environment. Without these pollinators, plant life will decline and affect human farmland as well.
Protect the environment and our precious insect life by following proper dust collection regulations in factories and other industrial workplaces.
