Requirements and Challenges

The company, AKDEM, is producing various types of fabrics: Fabrics made of natural fibers up to fabrics made of synthetic fibers or so-called chemical fibres. During this fabric production, a heat treatment is carried out in order to provide different physical properties to the fabric.

This heat treatment is done at AKDEM, in Brückner Stenter frames. The operating temperature of the Brückner Stenter frame can reach up to 210°C, or even higher depending on the fabric type.

On the exhaust outlet of the stenter frame, there is a high amount of smoke, wax and mist, which creates severe odor-intensive problem around the production plant. Therefore, AKDEM was looking for a filter unit to solve this exhaust gas problem.

Solution

  • VANTERM observed carefully the operating conditions, investigated the parameters of the project and calculated the required capacity. The exhaust gas temperature was too high, which was one of the challenges. However, this challenge was also the key for energy saving potential. It was very important to save this heat energy on the outlet, by providing an effective heat recovery together with the effective filtration.
  • Since the exhaust gas was composed of mist, wax and fume, it was obvious for VANTERM to use electrostatic filtration technology to provide an effective separation. Therefore, VANTERM installed ESP-600 electrostatic precipitator units (so-called electrostatic filter units) together with the integrated in-house heat exchangers. After the first day of installation, AKDEM has started to save valuable heat energy, and solve the odor problem at the exhaust of its stenter frames.
