Abstract
A process for treating hazardous particulate generated during a manufacturing process is provided. The process includes the steps of: passing particulate material through at least one duct toward a waste collection device; feeding an additive into the duct to be mixed with the particulate material, upstream from the waste collection device; and passing the particulate material mixed with the additive into the waste collection device. A scrap remelting apparatus is also provided.
Claims24
A process for treating and collecting metallic oxide impregnated dust generated during a manufacturing process comprising the steps of:
- passing particulate material through at least one enclosed area and toward a waste collection device;
- feeding an additive into the enclosed area to be mixed with the particulate material to create an additive-particulate material, upstream from the waste collection device;
- and
- passing the additive-particulate material mixture into the waste collection device.
A process for treating and collecting metallic oxide impregnated dust generated in a manufacturing unit during a manufacturing process comprising the steps of:
- passing the metallic oxide impregnated dust from a point of generation to a waste control device;
- mixing the dust with a binder by injecting into the manufacturing unit the binder at a position upstream from the waste control device;
- and
- feeding the dust and binder into the waste control device.
A process for treating metallic oxide impregnated dust, generated during a metals industry scrap remelting process, in an enclosed system comprising the steps of:
- passing gas containing dust generated in a cupola through at least one duct toward a bag house;
- providing means for injecting, within a scrap remelting manufacturing unit and upstream of the bag house, a binder;
- uniting and binding the additive with the dust in the duct by injecting, with the means for injecting, the binder into the duct;
- allowing the binder to mix with the gas;
- and
- collecting the treated dust and binder in the bag house.
A scrap remelt apparatus for recycling scrap metal comprising:
- a cupola for melting scrap metal;
- at least one duct for conveying gas containing metallic oxide impregnated dust generated by the cupola to a bag house;
- and
- means for injecting into the duct upstream of the bag house, a binder for binding with at least some of the metallic oxide impregnated dust.
