ZAKŁADY CHEMICZNE “Siarkopol” TARNOBRZEG sp. z o.o. have in their commercial offer products based on elemental sulfur, for direct use in industry or agriculture. Elemental sulfur is also used as a raw material for industrial production covered by special formal and legal and quality requirements. In its offer, the company has such products as:
- Granulated sulfur with bentonite (Vigor S, Vigor S Pro).
- Granulated sulfur with bentonite and boron (Vigor S with boron).
- Sulfur suspension fertilizer (Pro Sulfur S 800 S.C.)
The installed system is aimed at eliminating dust created during the sanitary process of transport and packaging of granulated sulfur. The installation was made for the ATEX explosion hazard zone.
Elimination of dust created during the sanitary process of transport and packaging of granular sulfur carried out by extracting dusty air from existing connection connectors to machines and additional places where sulfur dust accumulates dangerously. There are 17 extraction places in the installation. Suitable pipe diameters and grading selected to achieve a flow rate of 20 m/s.
Design of a filter control panel made of ANSI 304 steel. Filter chute equipped with pneumatic batters.
Radial fan made in
ATEX version. The maximum permissible
temperature of the transported medium
for fans in this version is 40
°.C. The housing, rotor and inlet hopper
are K304 solid, the rest of the steel
components of high quality. Antistatic
vibration compensators for inlet and outlet were used
. The foundation of
the ventilator on vibroisolators (on the foundation). The inspection hatch and the easily removable side of the fan provide easy access to cleaning.
The filter was protected with 4 pieces of membranes with a size of 920×586 installed just above the filter hopper and separated by a DN 500 return flap mounted on a 5-meter straight section of the inlet pipeline to the filter. The membranes and flap are complemented by break and actuation sensors.
When the decompression panel diaphragm break sensor is activated and/or the return flap is activated, the dedusting system is stopped, i.e., the fan is turned off, the purification process is interrupted.
Technical data of the dedusting installation:
|Filter unit capacity [m3/h]||14000|
|Fan power [kW]||30|
|Number of filter bags [szt.]||120|
|Total filtration area [m2]||228|
|Filter material||PTFE antistatic|
|Filter unit material||AISI 304 used Tractor|
Electrical installation and AKPIA:
Control of the dedusting system is possible from the operator panel mounted on the façade of the RO-1 power and control switchgear or from a push-button cassette mounted on the pollen system structure.
In order to properly control and monitor the condition of the dedusting system equipment, it is envisaged to use the following measuring devices:
- Vacuum transmitter on the clean and dirty side, on the dedusting unit.
- Decompression membrane break sensor.
- Explosion-proof flap operation sensor. The algorithm implemented in the PLC will enable the system to work in automatic mode, implementing the settings set by the operator through the control panel and in manual mode.
