Baghouse Dust Collectors

Scientific Dust Collectors manufactures a full line of Baghouse Dust Collectors to meet the needs of your specific operation. For over 28 years, SDC has provided customers with unmatched cleaning performance due to our superior cleaning system that employs a patented supersonic nozzle to clean the filters more effectively than any of our competitors.Baghouse Dust Collectors are ideally suited to capture dusts that are larger or more difficult to clean. Dusts that are high temperature or hygroscopic are better suited for collection in baghouse dust collectors. In addition, larger dust sizes (greater than 50 microns) and higher grain loadings (over 5 grains per cubic foot) are ideal for baghouse units. Dusts that have a tendency to form films that solidify should be handled in fabric baghouse collectors. If hydrocarbons are present in the airstream, the same problems may occur. For these types of applications, baghouses are recommended because the dust cake may require flexing before the cake will burst. Some examples of dust that are collected using fabric filter baghouses are: flyash, coal, cement, lime, fiberglass, paper, plastic, sawdust, and other stringy or irregular shaped dusts.

Top Removal

Scientific Dust Collectors’ Supersonic Pulse Jet Top Removal (SPJ-T) Collector is designed with a full walk-in plenum for easy bag access from the clean side. It utilizes the patented supersonic nozzle cleaning system as well as a high-side inlet so that the heavier dust falls out of the air stream. These features allow the collector to operate at higher air-to-cloth ratios, lower pressure drops, and provide longer filter life. The SPJ Series is a heavy duty reverse pulse jet dust collector that operates continuously without requiring the process to be shut down for cleaning. The walk-in feature on the SPJ-T Series allows bag changeout from the clean side while not being exposed to the elements. Our high side baffled inlet with dropout section slows to less than 3000 FPM, which allows the large particles to simply fall out of the airstream into the hopper. Our bag spacing of three (3) inches between bags is the widest spacing in the industry. This reduces reentrainment of the dust. Our nozzle based cleaning system eliminates the venturi at the top of the bag/cage. This allows us to get over 300% more cleaning air into the bag than other generic baghouses.We gaurantee a stabilized pressure drop in our baghouse to be lower than 3.5″WC at full rated airflow.

Railing Top

Scientific Dust Collectors’ Supersonic Pulse Jet Railing Top (SPJ-RT) Collector is designed for easy top bag removal from the clean side while maintaining low headroom. It utilizes the patented supersonic nozzle cleaning system as well as a high-side inlet so that the heavier dust falls out of the air stream. These features allow the collector to operate at higher air-to-cloth ratios, lower pressure drops, and provide longer filter life. This design has all the same benefits and features as our walk-in plenum design. The only difference is that the bags are accessed through “lift-off” doors on the roof of the baghouse. The Railing Top design allows bag access where outside temeprature is hot enough to prohibit entry into a walk-in plenum.

Bottom Removal Collector

Scientific Dust Collectors’ Supersonic Pulse Jet Bottom Removal (SPJ-B) Collector is designed for low-profile applications where headroom is a factor. It utilizes the patented supersonic nozzle cleaning system as well as a high-side inlet so that the heavier dust falls out of the air stream. These features allow the collector to operate at higher air-to-cloth ratios, lower pressure drops, and provide longer filter life. This design also has all the same benefits and features as our top bag access designs. The only difference is that the bags are accessed from the dirty air side of the baghouse.

Low Flow Bottom Removal Collector

Scientific Dust Collectors’ newest Supersonic Pulse Jet Low Flow Bottom Removal (SPJ-BL) Collector is economically designed for low-flow applications (less than 5,000CFM) and low static pressure (less than 14″ SP). It utilizes the patented supersonic nozzle cleaning system as well as a high-side inlet so that the heavier dust falls out of the air stream. These features allow the collector to operate at higher air-to-cloth ratios, lower pressure drops, and provide longer filter life.

bin-vent-collector

Bin Vent Collector

Scientific Dust Collectors’ Supersonic Pulse Jet Bin Vent (SPJ-BV) Collector is designed specifically for storage tanks, silos, work bins, and material receivers. It employs the patented supersonic nozzle cleaning system which allows the collector to operate at higher air-to-cloth ratios, lower pressure drops, and provide longer filter life. We can provide powered (with a fan) and non-powered (without a fan) bin vents. We can also customize the bottom flange to match customers’ required opening.

horizontal-collector

Horizontal Collector

Scientific Dust Collectors’ Supersonic Pulse Jet Horizontal (SPJ-H) Collector is designed for low headroom applications, similar to the SPJ-B Collector. It utilizes the patented supersonic nozzle cleaning system as well as a high-side inlet so that the heavier dust falls out of the air stream. These features allow the collector to operate at higher air-to-cloth ratios, lower pressure drops, and provide longer filter life. This special design uses horizontal bags that are accessed from the clean side of the unit. This is a specialty application unit where the dust is large and stringy, but there is a low headroom requirement.

insert-collector

Insert Collector

Scientific Dust Collectors’ Supersonic Pulse Jet Insert (SPJ-I) Collector is designed for conveyors, tanks, silos, air slides, cyclones, and bins. This self-contained dust collector is integrated into a current enclosure allowing dust to be retained where it is generated and can be custom designed to meet specific needs. It utilizes the patented supersonic nozzle cleaning system which allows for longer filter life while operating at higher air-to-cloth ratios, lower pressure drops, and provide longer filter life. This special design is often used as a retrofit fix to an existing baghouse, where the hopper and dirty air bins are in good working order. The customer either wants to increase the bag life, reduce the system pressure on the fan, or increase airflow through the baghouse. SDC’s retrofit design allows these changes to be effectively made in all baghouses, including baghouses made by other manufacturers. By providing our clean air section (insert) the customer obtains all the benefits of our cleaning technology at a reduced cost.
