Preheating and humidification treating apparatus that thick fiber type plate is produced; Comprise adjustable inlet valve, one-level steam-water separator, drain valve, air-introduced machine, adjustable inlet valve, main air heat exchanger, secondary steam-water separator, secondary air heat exchanger, humid air jet pipe and spreading machine; Said adjustable inlet valve is installed in one-level steam-water separator side; Said drain valve is installed in the bottom of one-level steam-water separator, and said adjustable inlet valve is installed in the bottom of main air heat exchanger, and said main air heat exchanger left side is equipped with air-introduced machine; Said one-level steam-water separator and main air heat exchanger communicate with the secondary steam-water separator through pipeline; Said secondary steam-water separator bottom is equipped with drain valve, is connected through pipeline between said secondary steam-water separator and the secondary air heat exchanger, and said secondary air heat exchanger bottom is equipped with adjustable inlet valve; The right side of said secondary air heat exchanger is communicated with the humid air jet pipe, and said humid air jet pipe and spreading machine link together.
Beneficial effect
The utility model can be brought up to 60 ℃-80 ℃ with the temperature of fibre mat by room temperature (about 20 ℃) in the forming process of mating formation, and in the low inside and high outside temperature field of the inner formation of slab, reduces hot pressing time, enhances productivity and output; Make fiber moisture increase 0.5%-2%, promote the decomposition and the degraded of part hemicellulose, lignin in the fiber hot pressing, increase between the fiber from bonding capacity; Improve the fiberboard internal bond strength; Thereby reduce the consumption of adhesive, reduce production costs, and improve the environmental-protecting performance of sheet material.
