Apparatus and method for controlling moisture in the manufacture of glass fiber insulation

摘要

Apparatus, systems and methods for monitoring and controlling the amount of moisture introduced into the forming hood area in the manufacture of mineral fiber insulation products. Moisture from coolant liquids, binder dispersions and binder diluents are all introduced deliberately into a forming hood; ambient moisture and water from combustion are additional sources. A series of global variable control valves, one for each fluid system; as well as individual variable control valves for each fiberizing unit are provided with associated meters. Sensors monitor fibrous pack conditions and ambient conditions and provide inputs to the valve control system. A specific 3-ring liquid dispensing system is also disclosed.

主权项

1. A manufacturing system for making a fibrous product, the system comprising:
a plurality of fiberizing arrangements associated with a conveyor movable in a machine direction, each fiberizing arrangement comprising:
a fiberizer configured to form fibers from a source of molten material;a blower configured to direct the fibers from the fiberizer toward the conveyor;a coolant fluid dispenser configured to spray the fibers with a coolant to cool the fibers;a plurality binder dispensers configured to atomize a binder dispersion and spray cooled fibers with the atomized binder dispersion;a controller programmed to adjust flow to at least one of said binder dispensers to provide atomized binder dispersion fluid droplets that are a different size than atomized binder dispersion fluid droplets provided by at least one other binder dispenser.
