Dry Fog Systems

How does it work?

DSI technology uses a special air-atomizing nozzle that produces a very dry fog to agglomerate and remove airborne dust particles from various material handling and processing operations. The DSI system utilizes compressed air and plain water to produce these 1-10 micron droplets (true fog). These ultra-fine water droplets attach (agglomerate) to like size airborne dust particles, sometimes referred to as PM-10 (particulate matter 10 microns or smaller). Subsequently, the slightly wetted dust particles become heavy enough to be removed from the air and fall back into the process. It is important to note that we only wet the dust, not the material. This results in very low water and power consumption, requiring no expensive chemicals or significant wetting of the product (always less than 1/2 % by weight, typically no more than 0.1% moisture addition).

Where does it work?

DSI fog systems have proven to significantly reduce fugitive dust from a variety of material handling points, including conveyor transfer points, trippers, reclaimers, crushers, screens, truck dumps, railcar loading/unloading, ship loaders-unloaders, and ash silo discharge chutes. DSI systems can meet all requirements for explosion hazard areas. Freeze protection can be provided for systems operating in temperatures as low as -35 degrees F. Due to a phenomenon known as "cloud physics", fog droplets will not freeze due to their lack of mass!

What are the advantages?

There are many advantages to the DSI system, including ease of installation, simplified maintenance, and flexible system configuration. The overall capital investment and operating costs can be more affordable than the cost of ventilation and chemical type systems. Additionally, system performance is often superior.These advantages are the direct result of using easy to install, pre-assembled modular components housed in protective enclosures. We supply complete systems comprised of electrical controls, filtration, regulation, supply lines and nozzle mounts. If required, DSI can supply all necessaryancillary items including air compressors, air receiver stations, pumps, and self-cleaning secondary filtration systems.

傳統(tǒng)噴霧除塵技術(shù)，產(chǎn)生的水滴直徑200-300μm，不僅效率低能耗高，而且往往會(huì)導(dǎo)致物料過(guò)分濕潤(rùn)，影響成品產(chǎn)量。DSI干霧抑塵技術(shù)可以產(chǎn)生1-10μm高度霧化的水霧顆粒，使水霧顆粒與粉塵顆粒充分碰撞凝聚，抑塵效果明顯優(yōu)于傳統(tǒng)噴霧除塵技術(shù)。
