Baghouses

 

 If your manufacturing processes create dust or other particulates, a baghouse may be the best alternative to the removal of these potential airborne hazards. Baghouses eliminate contaminants through a proven filtration process, leaving behind fresh air and cleaner facilities. They are long-lasting and often their maintenance and operational costs are more affordable than alternative ventilation systems.

We design and manufacture each baghouse or baghouse series to fit individual ventilation needs, taking into consideration: EPA discharge rates; byproducts; size and type of facility; air-to-cloth ratios.

Baghouse Ventilation Process

  1. Dirty air enters the baghouse through an inlet duct.
  2. Dirty air hits the inlet baffle (impact plates), causing heavy particulates to drop into the hopper or drop-out box below. This also causes the air to slow velocity for more efficient filtration.
  3. Air flows through the collector’s filtration bags, collecting fine dust or particulates on the outside of the bags as the clean air passes through the bags.
  4. The clean air is then moved to the stack and out into the environment, or recycled back into the facility to minimize heating costs.
  5. The collected particulates on the bags are dislodged by reverse-blown air and conveyed out to a disposal system.

Cartridge Collectors

 If your company processes produce dry particle or smoke emissions, a cartridge collector may be your best solution to air filtration. A cartridge collector parallels baghouse air filtration capabilities, yet does so while occupying less space. Due to two-inch-deep pleats on the cartridge bag, companies are able to utilize cartridge collectors in tighter spaces while still maintaining the highest of air filtration standards.

 
However, cartridge bag pleating can become difficult to clean and maintain if your industry processes produce moist particles. Make sure you are fully aware of the scope of emissions before installing a cartridge collector and work with our team experts to find the best ventilation solution for your needs. Yadkin Valley Mechanical is your professional Cartridge Collector Installer.

Fume Collectors
Many industries require air filtration when dealing with noxious fumes that are potentially harmful to employees. Hazardous airborne particulates (HAPS) require different ventilation solutions, all of which Yadkin Valley Mechanical, Inc. is capable of providing.

Scrubbers

Much like a baghouse, a scrubber cleans harmful fumes out of the air through a complex water-acid filtration process. They are best utilized if the contaminant being filtered is problematic due to a tacky or moist characteristic – one that would plug baghouse filters. Either wet or dry, scrubbers remove air toxicities and allow cleaner, lighter air to pass through the internal filters.

We take the greatest precaution when filtering HAPS, including using solutions such as high-efficiency Hepa filters or medium-efficiency filters for post-scrubber filtration. Only after the contaminated air has passed through multiple filtrations do we circulate it back into the facility or outdoor environment.

Fume Hoods and Testing

YVM also designs and builds fume hoods specific to the client’s manufacturing process. Once installed, our team performs fume hood testing to determine how much air is being drawn and how much is being expelled. These tests ensure that any HAPS are mitigated enough to keep employees and the environment healthy.

Converting Dust Control Systems
 
Tissue-based products converting and processing facilities inevitably deal with the hazards of airborne and “settle-out” dust issues. The issues that can arise include exposure to hazardous particles, random releases of dust into the air, increased fire and explosion risks, productivity issues, and difficulty maintaining a clean work environment.  Yadkin Valley Mechanical can help your company to reduce these issues through installation of custom-designed dust collection systems.
 
The installation of an YVM dust collection system starts by either thoroughly examining your building’s current installation, or by introducing you to plans for a whole new or upgraded system.
A typical engineered system will encompass the following design aspects:
 
  1. Dust particulates are collected through dust collection hoods that have been created for optimal performance, and fabricated to fit your unique building requirements in our fabrication shop.
  2. Both the dust collection hoods, as well as the ductwork required to gather and remove the excess particulates from the air, are then custom fabricated to fit each individual process or application.
  3. Next, we select the fans that will work most efficiently and in the most energy-efficient way based on each configuration’s particular airflow requirements.
  4. Finally, the appropriate separation device is selected based upon whether your needs require a dry collection system, a wet collection system, or even a combination of the two to in order to meet your dust handling objectives.
 
Our dust collection systems are also often integrated into your production department’s HVAC systems. This provides a combination of cost-effective handling with the efficient reuse of conditioned department air, both seasonally and year-round.

Other Devices
Often used as a method for pre-filtering or removal of heavy particulates, classifiers, cyclones and drop-out boxes are being used more frequently due to their economy of size and maintenance benefits. Pre-filters take the energy and velocity out of heavy particles within the air and drop them into a collection hopper below. For example, before entering a baghouse, contaminated air can pass through a pre-filter, leaving the lighter particulates for the baghouse, thereby increasing the life expectancy of the bags.

Classifiers

A classifier draws air in from the duct into its enclosure, at which point the air slows. After the air velocity decreases, it is spun horizontally, causing the heavy particles to be forced to the edges and drop into the hopper below. The lighter air then continues flowing into the baghouse for more extensive cleansing.

 

Drop-out Boxes

Drop-out boxes do not spin the air like a classifier or cyclone filtration system, but instead use a multitude of impact plates or baffles to slow the air and force the particulates to hit the impact plates and fall into the hopper. The plates are aligned vertically within the drop-out box enclosure to create a wave effect with the air as it passes from one end of the box through the other.

 

Cyclones

Similar to a classifier, a cyclone pulls air from the duct into the machinery’s cylinder. The air then goes through a vertical spinning process, forcing heavy particles downward. After being pushed through the bottom of the cyclone’s tail, the heavy particles drop and the air containing finer particles is pulled away into the baghouse for further filtration. Cyclones are best used in facilities that process a larger than average amount of heavy particles.
 
Pre-filtered air can also be expelled to other areas of the facility, without going through a secondary process, if the receiving area is void of employees or other air restrictions.

Stacks

 

Stacks
Stacks are the final step in an industrial ventilation system. It is an essential component as it ensures the air eliminated into the atmosphere is properly dispersed within regulatory requirements. 
 
The diameter and height of each unique stack is determined by the volume of air being discharged and dispersed. Regardless of height, a stack's discharge velocity will be identical, although higher stacks will produce lengthier throw. Throw regulations are determined by the Department of Natural Resources and must be abided by to ensure the environment is kept clean.
 
As the final component in many of our dust and fume collection projects, IVI has designed, fabricated and installed exhaust stacks in all sizes throughout the world. We have designed and fabricated stacks ranging from two feet to nearly 20 feet in diameter, in a variety of steel types including carbon, stainless, and Corten.  We also provide all the engineering and design to determine foundation requirements.
 
Our dust and fume collection designers can determine the height and discharge diameters of all our stacks to ensure compliance with any modeling requirements and other code stipulations. They will also determine the access platforms required to perform the testing required.

Tissue Machine Systems

 

Tissue-based products converting/processing facilities are inherently subject to the various hazards associated with the generation of airborne and “settle-out” dust issues. These issues include employee exposure hazards, uncontrolled fugitive atmospheric dust releases, increased fire and explosion risks, productivity issues and increased housekeeping requirements. We can assist your company to mitigate any and/or all such issues through the implementation of a custom designed dust collection system.

The implementation of any dust collection system begins with a thorough analysis of the current situation if it is an existing installation, or through review of new production equipment drawings in the case of new or upgraded equipment. A typical engineered system will encompass the following design aspects:
 
  1. Dust-laden air is collected through point-source dust collection hoods that are modeled and CFD analyzed for optimal performance, and fabricated to exacting and stringent requirements in our fabrication shop.
  2. A ductwork system is custom designed in our facility to fit any unique requirements. The system and its hoods are built to convey the dust to the final dust-handling separation device. 
  3. Appropriate fan(s) are then selected and optimized for efficient energy usage while performing to the system's airflow requirements.
  4. An appropriate separation device is selected, whether it be a dry collection system, a wet collection system, or a combination of both to meet the necessary final dust-handling objectives of your facility.
Yadkin Valley Mechanical dust collection systems are often integrated into the production department’s HVAC systems to provide the most cost effective installed systems while ensuring efficient reuse of conditioned department air, seasonally or year-around.

Trim and Broke Handling Systems
Trim Handling System

During the paper conversion process, many facilities can benefit from a trim and broke handling system. The continuous ribbons of trim that are created when re-sizing rolls can be easily transferred back into the process stream without manual labor. The same is true for unusable material pushed into the broke pit that needs to be recycled for future use.

Through easy-to-install air conveyer and vacuum systems, Yadkin Valley Mechanical creates a solution to pushing trim and broke carts throughout your facility. Such systems also reduce the risk of facility fires due to less dust buildup around the machine, rafters and trusses – common causes for ignition if not properly collected
