Description
Technical field
This technology is related to a kind of fiber boiling in fiberboard preparation process, defibrator process, drying system.
Background technology
Chip steaming device, defibrator, the drier being sequentially connected in series typically are used when preparing fiberboard, its technique is：
First wood chip feeding is connected with the boiling vessel of steam and softened, defibrator process is carried out in wood chip feeding defibrator after then softening again
Into fiber, then fiber is sent into drier again and is dried with high temperature air.Due to fiber and steam while being admitted to dry
In dry device, so drier is in addition to the target product needed to us is fiber drying, in addition it is also necessary to additionally steam is done
Dry, this invalid live load for increasing drier have impact on the rate of drying of fiber, waste the energy, also reduces fiber
Drying effect.In addition, the general also directly emptying of the hot-air discharged from drier, is not utilized, is also wasted
Thermal source.
The content of the invention
The purpose of this technology be to provide it is a kind of being capable of the effectively save energy and the good fiber boiling of fiber drying effect, heat
Mill, drying system.
The fiber boiling of this technology, defibrator process, drying system, including the wood chip with wood chip intake line and steam input pipe
Boiling vessel, defibrator, drier, the system also include the fiber steam with feed pipe, steam outlet pipe and fiber outlet pipe and separated
Device, it is chip steaming device, defibrator, the feed pipe of fiber steam separator, the fiber outlet pipe of fiber steam separator, dry
Dry device is sequentially connected in series, the steam input pipe of the steam outlet pipe grafting piece boiling vessel of fiber steam separator.
The beneficial effect of this technology：This technology, can be discharging due to fiber steam separator from defibrator
Fiber and steam effectively separated, it is to avoid substantial amounts of steam enter drier in, so the work of drier is main
Fiber is dried, drying effect is good, save energy；In addition, the steam isolated by fiber steam separator and quilt
Send into boiling vessel, realize reuse, further save the energy.
In above-mentioned fiber boiling, defibrator process, drying system, fiber steam separator has a variety of, fairly simple one kind, fine
The feed pipe of dimension vapor separation device is horizontal, and straight up, fiber outlet pipe is straight down or horizontal for steam outlet pipe
State.The fiber steam separator of this three-port structure is simple in construction, easy to use.Fiber steam separator also can be using rotation
Wind deduster, the side entry of cyclone dust collectors is feed pipe, and top exit is steam outlet pipe, and outlet at bottom is fiber
Outlet pipe.
Above-mentioned fiber boiling, defibrator process, drying system, in addition to carry out heat exchange with the hot gas discharged from drier
Heat exchanger.So, hot gas is carried out after heat exchange with the heat transferring medium in heat exchanger, and the waste heat of hot gas obtains profit
With, it is to avoid waste.Heat exchanger can be the shell-and-tube exchanger that heat transferring medium is water.
Brief description of the drawings
Fig. 1 is the schematic diagram of this technology.
Embodiment
This technology is further illustrated below in conjunction with the accompanying drawings.
Fiber boiling shown in Figure 1, defibrator process, drying system, including chip steaming device 1, defibrator 2, fiber steam
Separator 3, drier 4, shell-and-tube exchanger 5.There is wood chip intake line 11 and steam input pipe on chip steaming device 1
12.The three-port structure that fiber steam separator 3 is made up of feed pipe 31, steam outlet pipe 32 and fiber outlet pipe 33, feed pipe
It is horizontal with fiber outlet pipe, steam outlet pipe is straight up.Chip steaming device, defibrator, fiber steam separator enter
Expects pipe, the fiber outlet pipe of fiber steam separator, drier are sequentially connected in series, and steam outlet pipe 32 connects steam input pipe 12.With doing
The hot gas discharge pipe that dry device is communicated connects 41 and communicated with the shell side 51 of shell-and-tube exchanger 5, the tube side 52 of shell-and-tube exchanger 5
In lead to clear water.Dry gas input pipe 42 is also associated with drier 4.
In technology originally, the fiber come out from defibrator, as high-temperature steam is injected to drier together（Pipeline）In,
Due to the entrance of steam, the humidity of dried medium in pipeline is added, the rate of drying of fiber is drastically influence.This technology is intended to
Explore the power-saving technology in Fibreboard Production.This technology combination existing equipment situation, increases fiber steam point after defibrator
From device, fiber and steam is set to individually enter drier after separating（Pipeline）, and vapor then comes back to steaming after isolation
Boiler.On the one hand the vapor entered in drying duct is reduced, shortens the fiber drying time and reaches the effect of energy-conservation, it is another
Aspect, vapor is reclaimed, and similarly plays a part of energy-conservation.After dry terminate, the port of export of drying tube has and not had largely
Effect is collected, the warp of heat collection using the saturated vapor just arranged to air using shell-and-tube exchanger to these heats
Benefit of helping is obviously.On the select permeability of heat exchange medium, with clear water as heat can be caused during heat exchange medium
The heating surface area of exchanger greatly reduces.
