Description
Technical field
The utility model relates to the furfuryl alcohol field, particularly relates to catalyst recovery and furfuryl alcohol clarifying plant in a kind of furfuryl alcohol producing process.
Background technology
Furfuryl alcohol has another name called furfuralcohol, is a kind of important fine chemical material, is mainly used in to produce furfuryl alcohol resin, furane resin etc.Furfuryl alcohol also is a kind of good organic solvent, also can be used for synthetic rubber, agricultural chemicals and as rocket fuel.Furfuryl alcohol mainly by furfural and hydrogen the reaction in the presence of catalyzer carry out suitability for industrialized production.
The reaction formula of furfural and hydrogen reaction is: C
5H
4O
2+ H
2→ C
5H
6O
2+ Q, Q are reaction heat.Hydrogenation of furfural technology is generally carried out under high-temperature and high-pressure conditions, through excessive jar of sedimentation or after simply centrifuging goes out the part catalyzer, most of catalyzer enters water distilling apparatus with hydrogenation products, the existence of catalyzer has prolonged the cycle of operation of follow-up distil process, and easy blocking pipeline.After distilling out furfuryl alcohol, catalyzer is discharged with other high boiling material, and environmental pollution is serious.
At present domestic most of furfuryl alcohol producer adopts liquid phase medium-pressure or high pressure hydrogenation method to produce furfuryl alcohol, furfuryl alcohol and hydrogen react under the effect of catalyzer, after reaction finishes, mixture is put into the pond natural subsidence and is removed the part catalyzer, this method also has other some shortcomings except having the influence of above-mentioned catalyzer to follow-up distillation procedure and environment: required time of natural subsidence is long; Simultaneously, lower floor's waste residue outward appearance that precipitation produces is solid block, contains the organism of 48%-50%, has influenced the output of furfuryl alcohol, has wasted resource.Patent of invention CN101265244A " catalyst separation device in the furfuryl alcohol producing process and method " discloses a kind of catalyst separation device, mainly be to filter centrifugal the realization separating of catalyzer and furfuryl alcohol with tripodia by the video disc sedimentation is centrifugal, this method can be isolated most catalyzer in the furfuryl alcohol crude product, make the raw material that enters water distilling apparatus reach higher clarity, simplified follow-up distil process, cut down the consumption of energy, also alleviated pollution environment.But adopt this technology also to have following shortcoming: 1, centrifugation energy consumption height; 2, separation accuracy is not high.
Summary of the invention
Long at catalyst recovery inferior separating effect in the furfuryl alcohol producing process, cycle, shortcomings such as weak effect provide catalyst recovery and furfuryl alcohol clarifying plant in a kind of furfuryl alcohol producing process, to reach energy-conservation, reduce production costs, improve the purpose of separating effect.
For achieving the above object, the technical scheme that the utility model proposes is: catalyst recovery and furfuryl alcohol clarifying plant in a kind of furfuryl alcohol producing process, it is characterized in that, comprise the furfuryl alcohol crude product storage tank, dehvery pump, the ceramic membrane filter assembly that link to each other successively by feed pipe, in the ceramic membrane filter assembly ceramic membrane is installed, described ceramic membrane filter assembly dialyzate outlet links to each other with dialysate tank by the dialysis pipeline, and described ceramic membrane filter assembly concentrated solution outlet links to each other with furfuryl alcohol crude product storage tank by reflux line.
Further, under meter and interchanger are installed also on the described reflux line, interchanger can be realized the intensification of feed liquid or cooling.
Further, it is 20-800nm that described ceramic membrane separates the aperture, preferred 200-500nm.
Advantage of the present utility model is, adopt this device to carry out catalyst for furfural alcohol and reclaim the furfuryl alcohol clarifying plant with respect to adopting method centrifugal by the video disc sedimentation and that tripodia filters the centrifugation catalyzer in the former technology, can well realize separating of catalyzer and furfuryl alcohol, the clearance of catalyzer can reach more than 99%, improve the catalyst separating effect of catalyzer greatly, can reduce the content of catalyzer in the distillation ejecta greatly, alleviated environmental pollution, shortened operational path, cut down the consumption of energy.Ceramic membrane adopts the method for cross flow filter in addition, and it is contaminated that the film surface is not easy, and high temperature resistant, the anti-alkaline performance that ceramic membrane had, by cleaning, quick-recovery flux soon; And need compare stage by stage with adopting centrifugation catalyzer method in the former technology, adopt ceramic membrane to separate and to realize running without interruption, help shortening the production time.
