It is only used to conveniently, and if in fact disclose the utility model more than, it is not meant to automatically limit this application
Scope is any single utility model or utility model design.
This utility model provides the displacement cooking system of a kind of vegetable-fibre slurry, and its structural representation is as it is shown in figure 1, displacement is steamed
The system of boiling includes digester 4, hydrothermal solution groove 3, temperature liquid bath 2, displacement liquid bath 1, cold liquid pool 5, steam generator, liquid line
And circulating pump；Connected by main steam range between top liquid mouth and the steam generator of digester 4；Described hydrothermal solution groove, temperature liquid bath,
Displacement liquid bath, the liquid outlet of cold liquid pool are connected to the liquid-inlet of the bottom of digester by liquid line and circulating pump；Described
Digester 4 top liquid mouth is respectively connecting to hydrothermal solution groove 3, temperature liquid bath 2, displacement liquid bath 1 and the liquid-inlet of cold liquid pool 5；Steaming and decocting
Liquid outlet in the middle part of pot 4 is connected to the liquid-inlet of liquid medicine heater by liquid line, and the liquid outlet of liquid medicine heater leads to
Cross liquid line and be connected to the liquid-inlet of digester 4；Liquid medicine heater, hydrothermal solution groove 3 and temperature liquid bath 2 steam inlet all with
Steam generator connects；The temperature steam inlet of liquid bath 2 is connected with the steam (vapor) outlet of digester 4；At the top cover of described digester
Connecting and have medicinal liquid condenser, the cold liquid of pulp washing is filled by medicinal liquid and is compensated.
Displacement cooking system includes that gas piping and control valve, described hydrothermal solution groove 3 and temperature liquid bath 2 top are by gas piping and control
Valve processed connects.The bottom of the barrel of digester 4 and top are equipped with dismountable seam type sieve plate.Displacement cooking system includes that DCS operates

Ring pump and liquid medicine heater connect, and show digester 4, hydrothermal solution groove 3, temperature liquid bath 2, displacement liquid bath 1 and cold liquid pool 5 in real time
Liquid level, temperature and pressure, and control the switch of liquid medicine heater and circulating pump.
Utilizing middle pressure steam to heat system as heat energy carrier, the consumption of heat energy is mainly had two to introduce point by system, point
Not being liquid medicine heater and temperature, hydrothermal solution groove, decoction system is mainly heated, is main steaming by the effect of liquid medicine heater
Vapour exhaustion point, constitute about steam always, the 90% of consumption～95%, in order to ensure the pharmacology in groove tank remain stable and supplement from
So dispersed heat, needs to supplement from groove top part middle pressure steam in storing process, and the pressure moon of temperature liquid bath is
0.35～0.45MPa, the pressure of hydrothermal solution groove is about 0.50～0.60MPa.The steam that temperature liquid bath introduces is mainly used in heat-insulation pressure keeping, greatly
Account for the 5%～10% of steam consumption.
The liquid outlet of temperature liquid bath 2 is connected to cold liquid pool 5 after being sequentially connected with white liquor preheater, black liquor heat exchanger.Owing to reclaiming storage
The warm liquid measure deposited exceedes steaming and decocting institute, the warm liquid heat of needs, so the warm liquid of redundance is sent to alkali collection evaporation section, but
Still carrying above the average age for marriage heat energy in temperature liquid, this partial heat energy is reclaimed by white liquor preheater and black liquor heat exchanger, through the white liquor of preheating
Enter after mixing with temperature liquid, hydrothermal solution in digester 4, the temperature being effectively improved in digester, shorten the heating-up time, black liquor heat exchange
Device is positioned at the black liquid outlet of white liquor preheater, is mainly used in reclaiming the heat energy participated in temperature liquid, fills and heat when system carries out temperature liquid
When black liquor is filled, passing through shell side with the warm liquid after cool white liquid heat exchange, clear water carries out heat exchange by tube side collection, and the clear water of heating send
To washing workshop section for pulp washing, and the black liquor after heat exchange is sent to alkali collection evaporation section and reclaims.
Hydrothermal solution groove is connected by gas piping and control valve with temperature liquid bath top, in order to reclaim heat energy, after tablet steaming and decocting terminates,
Need the hydrothermal solution in digester to be cemented out with cold liquid.When hydrothermal solution flows into hydrothermal solution groove in a large number when, liquid and steam can cause
Pressure in hydrothermal solution groove rises rapidly, for keeping pressure stability, is connected with temperature liquid bath top by hydrothermal solution groove, and automatic valve control is used in centre
System.When the pressure in hydrothermal solution groove exceedes threshold value, valve is opened, and steam enters temperature liquid bath, is incubated for ftercompction.
The steam (vapor) outlet at temperature liquid bath 2 top is connected to gas cooler, and when system carries out hydrothermal solution filling, a large amount of temperature liquid stream enter temperature
Liquid bath, makes the steam in temperature liquid bath increase, and pressure quickly increases, when pressure surpasses state's threshold value, and the automatic exhaust steam valve at groove top is opened,
Excess steam discharges cooler in gas；Cooler is to reclaim the core of heat energy in highly concentrated on-condensible gas in the western army of displacement cooking to set
Standby.It is made up of tube side and shell side, and on-condensible gas walks tube side, and clear water walks shell side, and the thermal energy exchange that gas carries is to clear water and send
To washing workshop section for pulp washing.On-condensible gas after heat exchange becomes condensed water, stores to condensate water pot, when liquid level reaches threshold
During value, it is pumped to washing workshop section for pulp washing.This completes returning of highly concentrated on-condensible gas heat energy in whole displacement cooking system
Receive.This decoction system is normal pressure system, subsidiary medicinal liquid condenser, and the cold liquid of pulp washing is filled by medicinal liquid and compensated.
Above example is only in order to illustrate that the technical solution of the utility model is not intended to limit, although with reference to above-described embodiment to this
Utility model has been described in detail, and those of ordinary skill in the field still can be to specific embodiment party of the present utility model
Formula is modified or equivalent, and these are without departing from any amendment of this utility model spirit and scope or equivalent, all
Within the claims of the present utility model that application is awaited the reply.
