PULSE JET DUST COLLECTION
IMPULSE Filter
With thousands of Impulse Filter models built and shipped all over the world, this pulse jet dust collector has been one of Scheuch’s core products since 1979. With its robust design and proven reliability, customers can expect an uptime rate of over 99%. The Impulse Filter maximizes productivity in virtually every industry.
Rectangular Impulse Filter
Impulse filter bags are cleaned using compressed air pulses. A baffle plate diverts the dust-laden air upwards as it enters the filter casing. This process protects the filter bags from excessive wear and allows pre-separation of coarse particles. Compressed air retains the dust particles on the surface of the filter media and blows them off the bags. The separated dust falls into the hopper, and the discharge screw conveyor continuously conveys the separated material away from the Impulse Filter. The clean air leaves the system via the clean-gas chamber, or it can be fed back into the facility as return air.
Round Impulse Filter
The Round Impulse Filter is a compact, high-capacity separator. The round Impulse Filter primarily handles heavy-dust loads in crude gas, utilizing the same cleaning system as the rectangular filter. The round impulse filter acts as a centrifugal separator in the lower crude gas inlet area. Dirty air enters the cyclone in the lower area tangentially. The centrifugal separation method discharges the majority of the particles via the dust collection cone. The filter bags direct the dirty air upwards, ensuring the system remains clean. Its design allows it to separate large quantities of material and makes it suitable for use in pneumatic conveying and central vacuum applications.
Energy Minimizing
EMC
Scheuch’s EMC dust collector technology allows you to automatically isolate a broken bag and continue operations, minimizing downtime and maximizing production.
Traditional filter technologies are limited in their ability to optimize investment and maintenance costs based on function and filter bag lengths. Scheuch’s EMC technology sets new standards in pressure loss, cleaning pressure, bag length, and bag lifetime.
By using a patented, mirror-image control system to shut off individual modules, it is possible to combine online and offline operation. Such an advantage ensures constant, low differential pressure cleaning throughout operation, which minimizes the total cost of ownership with Scheuch’s EMC Technology.
Features and Benefits:
- Reduce compressed air usage
- Consistent bag cleaning with low-pressure compressed air (35-45 PSI) is less aggressive on the filter media, resulting in longer-lasting bags.
- Long bag technology allows for a greater filtration area within a smaller footprint.
SPACE MINIMIZING
SMC
Scheuch has developed a unique Impulse Filter with space-minimizing (SMC) technology to maximize performance when space is limited. The twin-jet nozzle reduces the amount of costly compressed air needed for cleaning and therefore extends bag life.
The SMC Impulse Filter performs equally as well as the classic round Impulse Filter with a volumetric flow from 3531 acfm (6000 Bm3/h). Almost all industrial dedusting applications that have limited floor space or ceiling height can utilize the horizontal design.
The SMC technology is designed in fewer assemblies, which allows for quick installation with minimal downtime.
Features and Benefits:
- Optimized crude gas flow
- Top-down airflow
- Longer bag life
SMC Technology makes changing bags easier. The pulse jet cleaning system with two-tiered diaphragm valves and a corresponding pilot valve with a tank-integrated design enables gentle, uniform cleaning through every individual bag, resulting in longer bag life. The patented support cage injector system with a design suited to industrial use ensures a tight seal using a snap ring to reduce dust emissions.
We used Computational Fluid Dynamics (CFD) to optimize dust and air flow conditions for the Scheuch SMC. The crude gas flow cover, which has flow rectifiers and baffle plates built in, ensures that the flow is spread out evenly from the top to the bottom of the filter bag. This enables high filter area loads alongside a low differential pressure. By preventing circulation bypasses or excessive local flow velocities, we avoid bag damage at the inlet area.
