Abstract
The invention discloses a kind of synergy enrichment facilities, are made of multi-effect evaporator and synergistic device, it is characterised in that：The steam inlet of the steam (vapor) outlet of the synergistic device and the multi-effect evaporator is closed by pressure control device and connected, and the material inlet of the material outlet of the multi-effect evaporator and the synergistic device is closed by feed arrangement to be connected；The synergistic device material outlet has sealing pressure valve；The steam that the synergistic device uses is superheated steam.
Description
Technical field
The present invention relates to a kind of enrichment facility more particularly to a kind of black liquid synergy enrichment facilities.
Background technology
In alkali recovery technique, it is a necessary operating unit that concentration is evaporated to black liquor.Theoretically, black liquor is dense
The concentration of contracting is higher, more conducive to subsequent combustion process, is also more conducive to the saving of energy.It is sticky since black liquid consistency is higher
Degree it is bigger, when viscosity reaches certain level, black liquor can be adhered on the heat-transfer surface of multi-effect evaporator so that evaporator without
Method works.Therefore, in actual production, black liquor can only be concentrated to about 50%~60% or so.
Pass through analysis, it has been found that the sticky black liquor of concentration can further be concentrated with superheated steam, this patent
It is exactly such a synergy design.
Invention content
The technical problems to be solved by the invention are to provide a kind of synergy enrichment facility, by multi-effect evaporator and synergistic device group
Into, it is characterised in that：The steam inlet of the steam (vapor) outlet of the synergistic device and the multi-effect evaporator is closed by pressure control device
The material inlet of connection, the material outlet of the multi-effect evaporator and the synergistic device is closed by feed arrangement and connected；It is described
Synergistic device material outlet has sealing pressure valve；The steam that the synergistic device uses is superheated steam.
Compared with existing device, a kind of advantageous effect of synergy enrichment facility is：Black liquid consistency is can further improve, profit
In subsequent combustion, conducive to energy saving.
Description of the drawings
Fig. 1 is a kind of structure diagram of synergy enrichment facility of the embodiment of the present invention.
Specific embodiment
Embodiment：
A kind of synergy enrichment facility of the present embodiment, is made of, the steam of synergistic device 2 goes out multi-effect evaporator 1 and synergistic device 2
The steam inlet 1-1 of mouth 2-1 and multi-effect evaporator 1 passes through pressure control device 3 and closes connection, the material outlet 1-2 of multi-effect evaporator 1
It is closed and connected by feed arrangement 4 with the material inlet 2-2 of synergistic device；2 material outlet of synergistic device has sealing pressure valve 2-3；Increase
The steam that effect device 2 uses is superheated steam.
The operation principle of the present embodiment is described below：
After Black Liquor Concentration to certain concentration, viscosity is higher, should not be concentrated again with multi-effect evaporator 1.It will
This sticky black liquor discharges multi-effect evaporator 1, into synergistic device 2 by feed arrangement 4.Superheated steam is passed through synergistic device 2.
In synergistic device 2, superheated steam and sticky black liquor are direct heat transfers, not viscous wall problem, therefore, can be by sticky black liquor into traveling
One step concentrates.
Since the temperature of superheated steam is far above 100 DEG C, sticky black liquor is further concentrated completing
Afterwards, it is still steam state, moreover, the water of concentration process evaporation is also steam state.These steam are imported multiple-effect by pressure control device 3 to steam
Device 1 is sent out, the further concentration to sticky black liquor had both been completed, and had also used the steam that concentration process evaporates, realize heat
Cascade utilization, so as to greatly energy saving.
Above example is only exemplary embodiment of the present invention, is not used in the limitation present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can make the present invention respectively within the spirit and scope of the present invention
Kind modification or equivalent replacement, this modification or equivalent replacement also should be regarded as being within the scope of the present invention.
