Abstract
The utility model provides a multifunctional papermaking black liquor vacuum concentrator, which is a device integrated with vacuum evaporation and concentration. The multifunctional papermaking vacuum concentrator uses not only steam but also conduction oil for heating up. A multistage centrifugal pump is used for pumping cooling water to produce certain pressure flow and inject the water into a hydraulic ejector. The hydraulic ejector sprays water through nozzles which are arranged symmetrically and uniformly at certain gradients under the action of certain waterflow. The sprayed water is focused on a point of intersection. Suction pressure is formed in the hydraulic ejector. Vacuum is produced in an air chamber. As secondary steam directly contacts with waterflow for heat exchange, most of steam is condensed into water. As the remaining small quantity of uncondensed steam and incondensable gas rubs high-velocity jetted waterflow, and is mixed with the high-velocity jetted waterflow, squeezed and discharged from a diffuser duct, higher vacuum is formed in the air chamber. The utility model provides the multifunctional papermaking black liquor vacuum concentrator needing low investment and running cost with simple operational procedures without secondary pollution, and the multifunctional papermaking black liquor vacuum concentrator is in particular applicable for medium and small papermaking enterprises.

Described bleeder valve connects and is welded on double-layer vacuum concentration kettle internal layer bottom centre with pipeline and is communicated with internal layer, described admission opening, oil outlet, safe valve opening, Pressure gauge, be welded on double-layer vacuum concentration kettle skin top and be communicated with corresponding inlet valve, delivery valve, safety valve, the Pressure gauge loaded onto with interlayer is interior.
Described drain valve, fuel feed hole, be welded in double-layer vacuum concentration kettle skin below and be communicated with corresponding drain valve, the inlet valve loaded onto with interlayer is interior.
Described: automatic control system is to connect temperature measurer, intake valve or inlet valve and feed liquor valve and Pressure gauge with lead.Main effect is that the signal that utilizes temperature measuring device to send is controlled steam inlet electromagnetic valve or conduction oil electromagnetic valve and liquid inlet electromagnetic valve, can arbitrarily set and regulate the matching degree of temperature in the kettle and admission pressure or conduction oil pressure and feed liquor amount, make it operate as normal.Behind the automatic control system electromagnetic valve, also set up hand control valve in addition, so that emergent the use guaranteed normal operation.
A kind of multi-functional black liquid vacuum concentrating apparatus of the utility model is a cover vacuum evaporation, concentration integrated equipment, can at random be installed in indoor and outdoor, can not only heat with steam, also available conduction oil is heated, the technical scheme of being taked is: utilize multipole centrifugal pump to take out cooling water, produce the certain pressure current, inject in the hydraulic ejector.Hydraulic ejector becomes the nozzle of certain gradient to spray by the even cloth of symmetry under the effect of certain current, accumulates on the intersection point, by hydraulic ejector, forms negative pressure, produces vacuum in the air chamber.Contact with the direct of current owing to indirect steam in addition, carry out heat exchange, most steam condense into water, the steam that is not condensed on a small quantity and on-condensible gas also owing to high-speed water jets mutual friction mutually, mix extruding, discharge by diffuser pipe, make and form higher vacuum in the air chamber.
Because air chamber and double-layer vacuum concentration kettle are the pipelines that sealing is connected, thus the interior negative pressure value of double-layer vacuum concentration kettle can reach-0.09MPa～-0.1MPa.Utilize the principle of negative pressure (need not to use pump) in the double-layer vacuum concentration kettle simultaneously, open liquid flowing valve, rare black liquor just sucks in the still continuously automatically, evaporates, concentrates.The rare black liquor that enters in the double-deck concentration kettle just can seethe with excitement in the time of 50 ℃～60 ℃, and evaporation produces a large amount of water vapours, and the water that is cooled is taken away, and under certain condition, temperature high evaporation amount more is big more,
