With reference to Fig. 1, Fig. 1 for embodiment of the present invention biomass by hydro-thermal liquefaction system a specific embodiment, the present embodiment
Biomass by hydro-thermal liquefaction system include:Reactor 1, the reactor 1 is used to carry out liquefaction reaction, and the reactor 1 connects
There are feed pipe 2 and product discharge pipe 3, pressue device 4 is serially connected with the feed pipe 2;Product collector 5, the collection of products
The outlet side airtight connection of device 5 and the product discharge pipe 3;Flow control structure 6, the flow control structure 6 is arranged at institute
State between product collector 5 and the reactor 1, and for control the product be expelled to by the product discharge pipe 3 it is described
The flow of product collector 5, so that the discharge flow of the product discharge pipe 3 is equal with the feed rate of the feed pipe 2.
A kind of biomass by hydro-thermal liquefaction system that the present invention is provided, is passing through feed pipe 2 and pressue device 4 to reactor 1
After the aqueous preheating material of interior press-in, the water in preheating material can receive thermal evaporation expansion in reactor 1, by reactor 1
Interior temperature and pressure is increased to respectively in the second preset range and the first preset range, has been preheated instead from there through preheating material
Answer device 1;Afterwards, preheating material can be replaced by reaction mass, and is pressed into reaction mass by feed pipe 2 and pressue device 4
In reactor 1, so that reaction mass is in the temperature and the pressure rings in the first preset range in the second preset range
Liquefaction reaction is produced under border, the product of liquefaction reaction is expelled in product collector 5 by product discharge pipe 3, and by flow control
The discharge flow of the control product of structure processed 6 discharge pipe 3, so that the feed rate of the discharge flow of product discharge pipe 3 and feed pipe 2
It is equal, so as to the temperature and pressure in reactor 1 is respectively retained in the second preset range and the first preset range.Thus,
Continuous to the feed of reactor 1 by feed pipe 2 and pressue device 4, and reactor 1 can continuously be discharged by product discharge pipe 3
While interior material, the temperature and pressure in reactor 1 is maintained at respectively in the second preset range and the first preset range,
So as to be capable of achieving the continuous reaction of biomass by hydro-thermal liquefaction system, and then be conducive to the scale metaplasia of biomass by hydro-thermal liquefaction
Produce.
It should be noted that due to when the discharge flow of product discharge pipe 3 is more than the feed rate of feed pipe 2, reacting
Material amount retained in device 1 is reduced, therefore the reaction pressure in reactor 1 is reduced, while during stop of the material in reactor 1
Between shorten, heat time of the material in reactor 1 shortens, and reaction temperature in reactor 1 is reduced;Conversely, when product is discharged
When the discharge flow of pipe 3 is less than the feed rate of feed pipe 2, the material amount retained in reactor 1 gradually rises, therefore reactor
Reaction pressure increase in 1, while the time of staying of the material in reactor 1 is elongated, heat time of the material in reactor 1
Elongated, the reaction temperature in reactor 1 is raised.Therefore, only when the discharge flow of product discharge pipe 3 is equal to entering for feed pipe 2
During stream amount, the reaction temperature and reaction pressure in reactor 1 just can be respectively retained in the second preset range and first presets
In the range of.
Wherein, preheating material can be water, or the mixture of biomass and water composition, here does not do concrete limit
It is fixed.Reaction mass is the mixture that biomass and water are constituted.
In addition, it is necessary to explanation, the first preset range is for needed for reaction mass in reactor 1 can carry out liquefaction reaction
Pressure limit, temperature range of second preset range for needed for reaction mass in reactor 1 can carry out liquefaction reaction.
Furthermore, product is continuously received in order to pass through product collector 5, preferred product collector 5 is multiple, when many
One in individual product collector 5, can be using other collection of products when for collecting the product discharged by product discharge pipe 3
Device 5 carries out the operation such as extraction or separation of product, and from there through product collector 5 the continuous reception of product is capable of achieving.Wherein, produce
The quantity of thing collector 5 can be two, three or four etc., and here is not specifically limited.
In the embodiment shown in fig. 1, reactor 1 can be tubular reactor, or tank reactor, here is not
It is specifically limited.
In the embodiment shown in fig. 1, pressue device 4 is used to material is pressed in reactor 1 along charging 2, it is preferable that pressurization
Device 4 is high-pressure plunger pump, and the power of high-pressure plunger pump is strong, and is easy to the intrusion for controlling to calculate reactant.
In order to control the flow that product is expelled to product collector 5 by product discharge pipe 3, flow control structure 6 specifically may be used
Including the flow control valve being serially connected with product discharge pipe 3, by adjusting the aperture of flow control valve product edge is can control
Product discharge pipe 3 is expelled to the flow of product collector 5, so that the feed stream of the discharge flow of product discharge pipe 3 and feed pipe 2
Amount is equal.
Wherein, the concrete structure of flow control valve is not limited, as long as can realize that product is arranged by flow control valve
The regulation of the discharge flow of outlet pipe 3.Example, flow control valve can be made as structure shown in Fig. 3, i.e. flow control valve
Including housing 61, housing 61 is provided with product inlet 67 and product exit 68, in housing 61, product inlet 67 and product exit 68
Between be formed with runner 62, inverted cone-shaped valve port 63 is provided with runner 62, also including tapered pin 64, the diameter small end of tapered pin 64
Fit through in inverted cone-shaped valve port 63, the end that is relatively large in diameter of tapered pin 64 is connected with leading screw 65, and leading screw 65 is stretched out outside housing 61,
And the axis of leading screw 65 is conllinear with the axis of tapered pin 64, the position of correspondence leading screw 65 offers and leading screw 65 on housing 61
The screwed hole that upper screw thread coordinates, leading screw 65 stretches out the one end outside housing 61 and is connected with handle 66, is by the rotating threaded shaft of handle 66
The aperture of adjustable valve port 63, thus have adjusted the aperture of flow control valve.
In addition, flow control valve can be manually operated being adjusted, it is also possible to be adjusted by automatically controlling,
This is not specifically limited.But, because compared to adjusting manually, the degree of regulation for automatically adjusting and accuracy are generally higher, because
This preferred flow control valve is automatically adjusted by automatically controlling, specifically, in order to realize flow control valve aperture from
It is dynamic to adjust, following two concrete implementation modes can be included:
The first implementation:Flow control structure 6 also includes pressure sensing cell (not shown) and the first control
Unit (not shown), pressure sensing cell is located in reactor 1, and for detecting the reaction pressure in reactor 1, first
Control unit is used for the pressure value detected according to pressure sensing cell, controls to adjust the aperture of flow control valve.
