Filters

Industrial filter systems collect and remove particulate matter (dust, smoke, fibers), and that create unhealthy and unwanted atmospheres, from the environment. In addition, filters recycle usable material. It ensures that the factory environment is clean and It also removes excess heat and humidity from the system. Air cleaners remove pollutants from the air and gas stream. It has a wide range of design types to ensure different air purification requirements. In the selection of the air purifier, parameters such as the amount of cleaning required, the conditions of the air and gas flow are effective. In addition, fire safety and explosion control should be taken into consideration in all device selections.

Types of filters commonly used in the industry;

  • Jet-Pulse Filters
  • Cyclones - Wet Filters
  • Electrostatic Filters

Jet- Pulse (Bag) Filters

Bag filters are used to capture dust in the dirty gas stream. The dust holding efficiency of bag filters and their capacity to meet legal requirements are better than electrostatic filters. However, they are subject to restrictions such as temperature and gas type.

Cleaning methods used in this system;

  1. Mechanical shaking
  2. Reverse air flow
  3. Compressed air jet

These filters occur in the optimum number of bags in the steel structure and selected in accordance with the nature of the dust, the body structure cleaning unit, air lock, convertor unit, automatic control system. The bags are long and cylindrical.

As User Engineering, jet-pulse filters can be cleaned more effectively than traditional cleaning methods. A small number of devices to be installed by considering system dimensions instead of system application per bag will be sufficient. Thus, all particles held in the filter and the inner chamber adhere to the bags and accumulate in the discharge bunker.

Sonic system has less air consumption than air shock systems. Installation can be made at a lower cost. Air shocks are effective in the upper regions of 40 - 45% with the pressure effect of the bags inside according to the filter sizes. However, the same effect does not occur as the air pressure loses its effect in the lower regions. Also, due to contamination, unplanned frequency of work cycles causes swelling required for cleaning, bag wear and the need to renew the bags. Low frequency sound waves created inside by the sonic system create the same effect in the whole area without leaving a blind spot in the chamber. The system has no damage to the bags and this ensures a 20% material life for your system.

The sonic system is effective in reducing pressure drop across the collecting surface, increasing the life of the filter bag, preventing hopper clogging.

The acoustic cleaning of the filters significantly reduces the use of compressed air. The sonic system is usually installed in the area close to the silo section under the filter bag, where they can assist in body cleaning and prevent deposits in the silo section.

Under the cleaning effect of the sonic system, the bags are not exposed to impact and knitting distortion caused by reverse landing.

Sonic system reduces the pressure difference. Keeps the filters clean and efficient by preventing the part impact effect.
