PLASTRATUM DIFFERENTIAL VOLUMETRIC FUME EXTRACTION

Plastratum Diff erential Volumetric Fume Extraction

Effi cient fume extraction is essential in safety critical chemical processing and complimentary to the extensive Plastratum range of fully automatic plant and ancillary equipment for the Metal Finishing industry and our numerous aerospace applications.

It is an application of technology that significantly reduces the volume of fume extraction exhausted from the plant and much reduces the loss of expensive heated factory air. In conjunction with ducting and scrubber systems designed and installed to DW154, this produces a safe, environmentally friendly and efficient fume extraction process. The process tank sequence and systems have integrated lids fitted that generally operate in the closed position and are only opened during the short time of loading or unloading the work piece flight bars. This enables the fume extraction volume on each process to be significantly reduced and is only converted to full volumetric flow when the process tanks lids are in the open position. The riser tubes, as shown in the accompanied photograph, are fitted with automatic dampers as well as manual dampers enabling the volume flow to be adjusted in line with the type of chemistry and process operating temperature. Tank lids, of which there are usually two per process, are moved from their rest horizontal position through 90 degrees by rotational shaft actuators. Each operation is controlled through the plant PLC controller, such that the opening of the lids and the opening of the riser damper allows the transporter to interface with the process and access the work for movement to the next sequential process. Following this operation, the lids and the automatic damper are returned to their original positions. These operations, which only allow full open tank fume volume to be operational, give the benefit of at much reduced fume extraction to atmosphere and has been measured to reduce the output volume as much as 70%. This in turn reduces the fume scrubber and ducting requirements, with significant installation, capital and operational cost reductions. Overall, the increase in cost of the lid technology is more than offset by the reduction in cost of the fume ducting, fume scrubber, fan and discharge stack to atmosphere. This technology allows operation of the scrubber at a constant volumetric flow, allowing automatic dampers, with operate in conjunction with the lids, to allow air flow from outside to balance the changing fume flow from the chemical plant. The use of unheated, external air for balancing reduces the operational cost still further The constant volume fume flow can also be balanced by integration of the fume fan under inverter control.
