(2) background technology
Alkylated reaction specifically refers to that iso-butane and alkene are obtained by reacting isoparaffin under the effect of catalyst, it is the conventional art in petroleum refining field, its product (alkylate oil) have low-sulfur, low-steam pressure, without advantages such as aromatic hydrocarbons, heats of combustion value, high-octane ratings, be desirable gasoline blending component.Conventional alkylation reaction is mainly divided into sulfuric acid process alkylation techniques and hydrogen fluoride alkylation techniques, but the two all also exists the problems such as insoluble serious equipment corrosion and environmental pollution, significantly limit its wide popularization and application.Ionic liquid is the emerging eco-friendly fluent material that a class is made up of zwitterion completely, due to the physicochemical properties of its uniqueness, as the designability etc. of extremely low vapour pressure, wide in range liquid temperature scope, good solvability, specific function, in alkylated reaction catalysis, cause the extensive concern of domestic and international many scholars.
Ionic liquid catalyst in use, its activity and selectivity slowly can reduce along with the prolongation of service time, in order to keep the catalyst in reaction system to have higher activity and selectivity, regularly must draw off part ion liquid, and supplementing into fresh ionic liquid.The catalyst drawing off reaction system is normally stored in the place of specifying, if processed not in time after drawing off, storage capacity can be increasing, not only causes environmental pollution, also can bring potential safety hazard.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides a kind of reasonable in design, safety and environmental protection, stops useless ionic liquid and store the environmental pollution that causes and the useless useless ionic liquid treating apparatus of potential safety hazard in a large number, solve problems of the prior art.
The present invention is achieved through the following technical solutions:
A kind of useless ionic liquid treating apparatus, comprise useless ion flow container, horizontal type screw settling centrifuge, Clear liquid tank and oil skimming tank, the bottom discharge mouth of described useless ion flow container is connected through the charging aperture of a valve with a screw pump by pipeline, the discharging opening of screw pump is connected by the charging aperture of pipeline with a blender, the discharging opening of blender is connected with the charging aperture of horizontal type screw settling centrifuge by pipeline, a slag notch is provided with in the side, bottom of horizontal type screw settling centrifuge, the liquid outlet being located at opposite side bottom horizontal type screw settling centrifuge is connected with its top feed mouth of Clear liquid tank by pipeline, the finder outlet of Clear liquid tank is connected with the charging aperture of oil skimming tank, the bottom discharge mouth of Clear liquid tank is connected with the charging aperture of blender after a clear liquid circulating pump by pipeline, fresh alkali lye import and an exhaust outlet is provided with at the top of Clear liquid tank.
Described blender is pipe-line mixer.
The invention has the beneficial effects as follows: this useless ionic liquid treating apparatus, reasonable in design, reacted by useless ionic liquid and NaOH solution, useless ionic liquid is processed, make the composition in ionic liquid generate the solid slag of easy to handle metal to recycle, safety and environmental protection, has stopped useless ionic liquid and has stored the environmental pollution and potential safety hazard that cause in a large number.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is structural representation of the present invention.
In figure, 1 useless ion flow container, 2 horizontal type screw settling centrifuges, 3 Clear liquid tank, 4 oil skimming tanks, 5 screw pumps, 6 blenders, 7 clear liquid circulating pumps, 8 fresh alkali lye imports, 9 exhaust outlets, 10 slag notches, 11 liquid outlets.
(5) detailed description of the invention
