In recent months, the WOLFF GROUP received an order for the installation of a system for the offtake of dusts from the reactor after the carbonisation process in the waste thermal decomposition system. The delivery will be completed in the “turnkey” standard. This means that our company will be responsible for the supply of all the components and equipment, their installation and commissioning at the customer’s facilities. This is not the first order from this customer which confirms the reliability and quality of our previous deliveries.
The ordered solution consists of a modern cyclone filter with a support structure, connected with a vacuum blower, an ATEX magnetic separator and pipework. Due to the fact that the dusts are explosive in nature, it is necessary to apply the required protection measures. In this case, an explosion venting system with decompression panels will be used to protect the cyclone filter. Its operation is based on the fact that in normal working conditions, it maintains a full hermetic seal of the system, regardless of the filter inserts cleaning system operation. In case of an explosion in the unit, the panels open, releasing the overpressure and flame into the environment.
Additional elements included in the system of protections, responsible for explosion decoupling, will be a rotary batcher and a return gate. The batcher forms a passive barrier for the explosion from the dust release side, while the return gate isolates the duct system from the filtration unit in such a way, that the potential effects of the explosion cannot propagate through the duct system and into the facility.
Thermal rubber waste decomposition technology
The process of thermolysis performed in a thermal rubber waste decomposition system takes place in a horizontal reactor, and it consists in heating up waste material up to temperatures of 340÷400°C, the outcome of which is the release of organic components of the waste in either gaseous or solid form. In subsequent stages of the process, gaseous fuels, oily products, steel scrap and carbon compounds such as char are obtained. Chars, i.e. carbonisation products, contain ca. 40% of unburnt coal which conforms with neither EU standards nor Polish legal regulations, and therefore it is not suitable for storage without thermal reprocessing. In order to free the reactor of the remaining char, it is removed by means of a dedicated industrial vacuum cleaner, then to be stored in sacks known as big bags.
SCOPE OF WORKS: supply of all the components and equipment, and installation of the system for the offtake of dusts from the reactor after the carbonisation process
