Industry: Woodworking industry
Project objective: Reduction of dust and chip waste disposal for woodworking and furniture manufacturing lines (dust explosion class St1).
NEU-JKF, with many years of experience in designing industrial dust extraction systems, has carried out a comprehensive investment at the Wolność Meblarska plant in Lidzbark. The installation was designed in close cooperation with the client, taking into account the technological requirements of production and applicable environmental standards. The scope of the project includes dust removal using SuperJet filters, as well as safe transport of waste – mechanical to containers and pneumatic to the boiler room bunker. The investor’s confidence in NEU-JKF’s competence allowed the implementation of a solution that is reliable, energy-efficient and prepared for long-term, stable operation.
Key elements of the installation
The system includes 2 technological systems.
1. LINE
At the center of the implemented system is the SuperJet bag filter, which, thanks to its high efficiency and separation effectiveness, perfectly manages the removal of dry dust from the air.
– Capacity: 23,000 m³/h.
JK-60MTD 45kW fan mounted next to the filter controlled by inverter to adjust the power consumption according to the current extracted air demand.
– Capacity: 23,000 m³/h.
The JK-50EXS rotary valve, made in accordance with the ATEX directive, is an explosion barrier.
A non-return flap installed on the main pipeline prevents the spread of a possible explosion.
Fire flap. on the air return to the production floor.
Control system – control cabinet with operator panel, sensors, inverters, wiring.
CLS Loading System.
2. LINE
At the center of the implemented system is the SuperJet bag filter, which, thanks to its high efficiency and separation effectiveness, perfectly manages the removal of dry dust from the air.
– Capacity: 38,000 m³/h.
JK-70MTD 55kW fan mounted next to the filter controlled by inverter to adjust the power consumption according to the current extracted air demand, with sound-absorbing cabin.
– Capacity: 38,000 m³/h.
The JK-50EXS rotary valve, made in accordance with the ATEX directive, is an explosion barrier.
A non-return flapinstalled on the main pipeline prevents the spread of a possible explosion.
Fire flap. on the air return to the production floor.
Block grabber on the extraction thread.
Control system – control cabinet with operator panel, sensors, inverters, wiring
CLS Loading System.
Technical solutions
In both installations, the air is directed back into the hall or outdoors by means of a summer/winter flap.
The first component of both installations are SuperJet vacuum filters of minimized size, which are responsible for dedusting the woodworking and furniture production lines. The units are equipped with a VFV® explosion force decoupling system. Both cleaning systems feature the patented Power Pulse® system, which allows cleaning while the filter is running. Power Pulse® is currently the lowest-cost solution in its class to operate.
The material from under the filters fed to the container by means of the CLS system with a lid lowered onto the container and equipped with auger dispensers. From under the filter No. 2 it is possible to dose to the pneumatic transport hopper, which transfers the material to the boiler room. This pneumatic transport system is equipped with a JK-40D fan with a capacity of 7000 m³/h, 2 JA-100 cyclones and a B-500EXS airlock in ATEX-compliant design. Ultimately, the dosing system for the container and boiler room is to be fully automated.
Fans controlled by inverter and pressure sensor, are mounted on the clean side, which saves up to 30% of electricity. Each time the machine is turned off, the power consumption will be reduced. Seated on the ground next to the filter, it facilitates service access. The use of extruded elbows reduces resistance on the installation, so smaller motors can be used in the fans.
The entire plant has been designed in accordance with the requirements of the ATEX directive, which guarantees safe operation also in conditions of dust explosion risk.
In addition, NEU-JKF has installed a complete piping system for both dust collection plants.
Security solutions
The system is equipped with ATEX-compliant components, ensure safe operation in explosive environments. VFV® explosion diaphragms are located on the roof of the filter, eliminating the need for safety zones around the unit. Backflow preventers during an explosion in the filter prevent flames and pressure from reaching the production floor. Airlocks mounted under the filter provide a barrier to the explosion. The filter is made of thick hardened sheet metal which guarantees high resistance to the force of an explosion.
Benefits for the investor
Clean air: Effective dust removal improves air quality in the workplace, supporting the protection of employee health and the environment. Safety: Meeting the requirements of the ATEX directive reduces the risk of explosion, raising the level of operational safety of the plant.
Efficiency: Reducing dust improves production processes, improves product quality and reduces the likelihood of equipment failure. The implementation of modern technologies makes it possible to reduce electricity consumption and use waste as fuel in the plant’s boiler room.
Summary
The realization for the Freedom Furniture plant exemplifies NEU-JKF’s modern, holistic approach to dust collection systems in the woodworking industry. The combination of proven engineering competence and innovative technologies creates installations that raise standards of quality, safety and environmental responsibility in production.
