TOXIC MATERIAL CLEANING SYSTEM
Quirepace has completed the design, manufacture, and installation of a BVC Centralised Vacuum Cleaning System for the removal of Lead Sulphate, and Lead Oxide which have bulk densities ranging from 1030-1890 kgs/cubic meter.

The system comprises six hose connection points located throughout the facility which are interconnected with a heavy-weight pipework system and connected back to a filter separator and exhauster unit located at ground level.
The system is designed for two operators to be distributed around the pipework system using a 51 mm flexible hose and tool, carrying out general good housekeeping vacuum cleaning duties.
The extracted products, which are mainly powders and small granulates are separated from the
conveying air within a filter separator, having filtration media cleaned by the reverse jet technique.
The materials are dispensed through a double dump valve system into a screw conveyor for onward
processing.
Due to the potential harmful toxic nature of the materials being handled, located between the
primary reverse jet filter separator and the inlet of the exhauster unit, alongside is a high efficiency
particle arrest (HEPA) grade H13 filter having an efficiency of 99.997% @ 0.3 ΞΌm.
Motive conveying air for the system is generated by an exhauster package, provided with a vacuum
breaker, silencers, and powered by a 22.0kW motor all located within a forced draft ventilated acoustic
enclosure. This ensures emitted noise levels are below 75dB(A) at 1 metre measured under free field
conditions.
The plant was supplied complete with a sequenced electrical control panel manufactured in
accordance with the clientβs specification, and including the required motor starters and capable of
generating the required control voltage.
