In order to control combustible dust, dust collection is essential. However, when you are thinking of setting a new system or considering the installation of additional elements in order to comply with NFPA and OSHA standards, choosing the right type of dust collection solution is important. There are a number of factors you have to consider to select the appropriate dust collection system for yourself. The first step is determining whether you need wet or dry dust collection. Typically, wet and dry dust collection make use of different technologies and have differences in application. This makes it easier for them to collect a certain type of dust.
To collect dry dust, dry media dust collectors are typically used. They are also known as air separators. Wet dust collectors or wet scrubbers are used to collect wet dust. These are the primary dust collectors in the industry. Apart from these, there are many different subtypes in the market.
Collection of Dry Dust
According to the NFPA, dry dust collectors are appropriate to collect combustible dust in the surroundings. Some examples are media collectors or cyclones. In air separators, dust is collected through an inlet where air is forced through a filter media. The dust will subsequently get dislodged from the filters into a bag, where it will then go to the storage compartment. This storage compartment needs to be emptied regularly.
Generally, whether the dry dust collection is efficient or not is dependent on the filter as well as the filter media, the size of the particulate matter, air pressure and type of combustible dust that exists in the environment.
Wet Dust Collectors
Wet dust collectors are also known as wet scrubbers. They include cyclonic, venturi or centrifugal scrubbers. These scrubbers use a mix of air pressure and water in order to remove dust from the air. Scrubbers will first drive dust through water spray or water stream. The dust will then end up at the bottom of the tank. Gravity separates the dust and the dust will eventually fall into a storage container. If a cyclonic system is used, dust will be driven to the bottom through water flow. The dust will settle at the bottom, and the scrubber will need to be cleaned. Wet dust collection is generally very efficient and is able to capture particles that are very small.
