Abstract
The utility model discloses an energy-saving wood fiber hot-grinding and drying device, comprising a wood chip steaming machine, a hot-grinding machine and a drying pipeline, which are sequentially connected in series. A filter-steam separating device is further arranged between the hot-grinding machine and the drying pipeline; the filter-steam separating device comprises a feeding opening, a steam outlet and a fiber outlet; the feeding opening is connected with a discharging opening of the hot-grinding machine; the fiber outlet is connected with an inlet of the drying pipeline; and the steam outlet is connected to a steam input opening of the steaming machine. The energy-saving wood fiber hot-grinding and drying device provided by the utility model is provided with the filter-steam separating device, so that fiber and steam which are discharged from the hot-grinding machine can be effectively separated; and a large amount of the steam is prevented from entering a drier. The drier is used for mainly drying the fiber, so as to achieve good drying effects and save energy. Furthermore, the steam separated by the filter-steam separating device is sent to a steaming tank again, so as to recycle and further save the energy.
Description
Technical field
The utility model relates to a kind of fiberboard processing technique field, specifically is a kind of lumber fibre boiling, defibrator process, drying device.
Background technology
Generally to use chip steaming device, defibrator, the drier of series connection successively during the preparation fiberboard; Its technology is: will send in the boiling vessel that is connected with steam wood chip earlier and soften; And then softening back wood chip sends into and carries out defibrator process in the defibrator and become fiber, then sends into fiber in the drying duct again and carries out drying with high temperature air.Because fiber and steam are admitted in the drying duct simultaneously; So be the fiber drying except the target product that contains our needs in the drying duct, also include a large amount of steam, because the existence of steam; Increased humidity; Influence the rate of drying of fiber, wasted the energy, also reduced the drying effect of fiber.In addition, the hot-air of from drier, discharging is also directly emptying generally, does not utilize, and has also wasted thermal source.
The utility model content
The deficiency that the utility model technical problem to be solved exists to above-mentioned prior art, and a kind of effectively energy savings and effective lumber fibre defibrator process, the drying device of fiber drying are provided.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of lumber fibre defibrator process, drying energy saving device; The chip steaming machine, defibrator and the drying duct that comprise series connection successively; It is characterized in that: between described defibrator and drying duct, also be provided with a fiber steam separator; This fiber steam separator comprises charging aperture, steam (vapor) outlet and fiber outlet, and described charging aperture is connected with the discharging opening of described defibrator, and described fiber outlet is connected with the import of described drying duct; Described steam (vapor) outlet is connected to the vapor inlet port of described precooker.
Be provided with air blast in described fiber outlet lower end, the air outlet of air blast is relative with the import of described drying duct.
The charging aperture of described fiber steam separator is the level of state, steam (vapor) outlet straight up, fiber outlet is straight down or be the level of state.The fiber steam separator of this three-port structure is simple in structure, easy to use.The fiber steam separator also can adopt cyclone dust collectors, and the sidepiece inlet of cyclone dust collectors is feed pipe, and top exit is steam and goes out pipe, and outlet at bottom is fiber and goes out pipe.
On the hot gas discharge pipe of described drying duct, also be connected with a heat exchanger.Described heat exchanger is a shell-and-tube heat exchanger.Like this, after the heat transferring medium in hot gas and the heat exchanger carried out heat exchange, the waste heat of hot gas obtained utilizing, and has avoided waste.Heat exchanger can be that heat transferring medium is the shell-and-tube exchanger of water.
The beneficial effect of the utility model: the utility model is owing to have the fiber steam separator; Can separate the fiber of from defibrator, discharging effectively with steam; Avoid a large amount of steam to get in the drier; So the work of drier promptly is mainly fiber to be carried out drying, drying effect is good, saves energy; In addition, be admitted to again in the cooker, realized reuse, further practiced thrift the energy by the isolated steam of fiber steam separator.
Description of drawings
Fig. 1 is the sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Referring to fiber defibrator process, drying device shown in Figure 1, comprise chip steaming jar 1, defibrator 2, fiber steam separator 3, drying duct 4, shell-and-tube exchanger 5.Have wood chip intake line 11 and steam input pipe 12 on the chip steaming jar 1.The three-port structure that fiber steam separator 3 is made up of charging aperture 31, steam (vapor) outlet 32 and fiber outlet 33, charging aperture and fiber outlet are the level of state, and steam (vapor) outlet is straight up.The feed pipe of chip steaming jar, defibrator, fiber steam separator, the fiber outlet of fiber steam separator, drying duct are connected successively, and steam (vapor) outlet 32 connects steam input pipe 12.The hot gas discharge pipe that communicates with drying duct connects 41 and communicates with the shell side 51 of shell-and-tube exchanger 5, logical clear water in the tube side 52 of shell-and-tube exchanger 5.Also be connected with dry gas input pipe 42 on the drying duct 4.
In the technology originally, the fiber from defibrator comes out along with high-temperature steam is injected in the drier (pipeline) together, because the entering of steam has increased the humidity of drying medium in the pipeline, is having a strong impact on the rate of drying of fiber.The utility model is intended to explore the power-saving technology in the Fibreboard Production.The utility model combines the existing equipment situation, behind defibrator, increases the fiber steam separator, enters into drier (pipeline) after making fiber and steam separating separately, and steam then comes back to boiling vessel after separation.Reduce the steam that enters into drying duct on the one hand, shorten the fiber drying time and reach energy-conservation effect, on the other hand, steam reclaims, and plays energy-conservation effect too.After drying finished, the port of export of drying tube has a large amount of utilizations not yet in effect, and just row was to the saturated vapor of atmosphere, and the use shell-and-tube exchanger is collected these heats, and the economic benefit of heat collection is very tangible.On the selection problem of heat exchange medium, can be during as heat exchange medium with clear water so that the heating surface area of heat exchanger significantly reduces.
