Filter Systems For

The flue gas of stenter machine contains dense textile fluff. The first unit of the system is the pre-filter unit. The purpose of the pre-filter is to filter the textile fluff before it reaches the air/air heat recovery and air/water heat recovery units.

There are three different model options available, namely single-stage, double-stage, and coupled with air/air heat recovery unit. Model selection is made according to process density and operational needs.

The pre-filter has a high particle retention capacity and is equipped with pollution detection and automatic cleaning system. It automatically detects pollution and activates the cleaning system without the need for any operator intervention. The frequency of cleaning varies depending on the working hours and process density.

Some of waste heat of the stenter machine is transferred to clean cold air at air/air heat recovery unit. Plate heat exchangers, developed based on engineering calculations and analysis programs, are produced as air/air exchange cells according to the dimensions.

In the air/air heat recovery unit, hot clean air is produced between 90°C and 110°C by using the exhaust gas that its temperature between 120°C and 200°C. By returning the clean hot air to the appropriate locations of the stenter machine, fuel (natural gas) consumption is reduced.

It has pollution detection and automatic washing system. Without requiring any operator intervention, it automatically detects pollution and activates the washing system. The frequency of washing varies according to the working hours and process density.

In the air/water heat recovery unit, the other part of the waste heat of the stenter machine is transferred to clean cold water. The air/water heat recovery exchanger is a plate heat exchanger.

In the air/water heat recovery unit, hot clean water is produced between 50°C and 60°C by using the exhaust gas.The hot water can be used in any part of the factory where it is needed to save energy.

The unit has an automatic washing system that activates when it is time to wash without requiring any operator intervention. The frequency of washing varies depending on the working hours and process density.

Stenter machines have to oil vapor, volatile organic compound (VOC-TOC) and odor emission. The exhaust gas, whose temperature is lowered by heat recovery units, is sent to an electrostatic filter. In the electrostatic filter, the exhaust gas is ionized by being exposed to high voltage. Then, as it passes through plates with opposite charges, pollutants are captured and filtered out. As a result; oil vapor, volatile organic compounds (VOC-TOC) and odor particles are filtered.

The unit has an automatic washing system that activates when it is time to wash without requiring any operator intervention. The frequency of washing varies depending on the working hours and process density.

The flue gas washing filter system is developed for different processes and sectors. The flue gas is washed with water curtain after passing pre-filters and heat recovery systems. The system filters oil vapor, volatile organic compounds (VOC-TOC) and odor from the flue gas. The washing water reused after passing from an oil separator. Although there is continuous water consumption due to evaporation in the flue gas washing system, water consumption is low because the washing water is reused.
