Abstract
The utility model discloses a recovery device for nickel-bearing catalyst, which comprises a primary settling tank, a recovery tank, a fore magnetic filter, a secondary settling tank, a circulating magnetic filter, a circulating pump, a capture tank, a capture pump and the like. When in use, the produced hydrogenated xylitol liquid is drained into the primary settling tank for settling of the catalyst. Then, the hydrogenated xylitol liquid is drained into the fore magnetic filter for secondary settling. Thereafter, the feed liquid is used to flush the catalyst in the fore magnetic filter, the secondary settling tank and the circulating magnetic filter to the capture tank. Finally, the capture pump is started up to pump the catalyst to the recovery tank. The utility model has the advantages that the catalyst is fully recovered, the structure is simple, the operation is convenient, the effect is favorable and the like.
Description
Technical field
The utility model relates to a kind of retracting device of nickel-containing catalyst.
Background technology
The recycling problem of catalyst in the xylitol hydrogenation system production process is the urgent problem that solves of needs that affiliated industry faces.Owing in xylitol hydrogenation system production process, need to use a large amount of catalyst, if directly discharging can cause production cost to increase greatly, and can bring certain unsafe factor, also cause the huge waste of resource, bring huge infringement to society.As everyone knows, catalyst has very high economic recovery value, but at present the recycling to the catalyst used in the xylitol hydrogenation system is not very desirable: to reclaim the method for catalyst generally be hydrogenation technique situation according to separately to the industry at present, finish back sedimentation in reactor as hydrogenation, filter through plate and frame type filter-press again.This method not only reclaims not thorough, and the removal process catalyst exposes have potential safety hazard in air, causes catalyst consumption to rise and production cost increases, and economic worth is little.
Summary of the invention
At above-mentioned the deficiencies in the prior art, for reaching the thorough recycling of catalyst, realize that production cost hangs down and the purpose of good product quality, the utility model provides a kind of retracting device of nickel-containing catalyst, its have simple to operate, energy consumption is low, recovery is thorough, the economic worth advantages of higher.
The utility model is achieved through the following technical solutions:
A kind of retracting device of nickel-containing catalyst comprises primary settling tank, accumulator tank, preposition magnetic filter, secondary settlement groove, circulation magnetic filter, circulating pump, capture slot, seizure pump; Wherein, accumulator tank is connected the primary settling tank bottom, and the secondary settlement groove is connected with primary settling tank by preposition magnetic filter; The secondary settlement trench bottom is connected with the circulation magnetic filter by circulating pump, and secondary settlement groove top is connected with circulation magnetic filter top, forms a loop between secondary settlement groove, circulating pump, the circulation magnetic filter three; Circulation magnetic filter top is provided with passage, is connected with the equipment of next process; Preposition magnetic filter all is connected with capture slot with circulation magnetic filter bottom, and the capture slot bottom is connected with accumulator tank by catching pump.
Be equipped with valve on the interface channel of described each assembly.
When causing catalyst recovery to descend when preposition magnetic filter, circulation magnetic filter long-play, a large amount of catalyst can occur and enter degradation phenomenon under secondary settlement groove, the hydride printing opacity, carry out the fresh water (FW) flushing to two magnetic filters, its technological process is: 1, circulating pump → preposition magnetic filter → capture slot → seizure pump → accumulator tank; 2, circulating pump → circulation magnetic filter → capture slot → seizure pump → accumulator tank.
Hydride light transmittance 〉=90% after retracting device of the present utility model is handled changes the control that the back operation is convenient to other index over to, has realized the thorough recycling of catalyst.The present invention has adopted sedimentation, magnetic filtration treatment technology, and after handling, catalyst n i is recycled fully, reaches the purpose of economical operation, has realized the recycling of xylitol hydrogenation production system catalyst.Catalyst recovery devices of the present invention has advantages such as simple in structure, easy to operate, effective, and catalyst recovery method of the present invention has technology advanced person, low, simple to operate, the rate of recovery advantages of higher of energy consumption.
Description of drawings
Fig. 1 is the structural representation of retracting device of the present utility model.
Wherein, 1, hydrogenation still; 2, primary settling tank; 3, preposition magnetic filter; 4, secondary settlement groove; 5, circulating pump; 6, circulation magnetic filter; 7, accumulator tank; 8, catch pump; 9, capture slot; 10, valve.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of retracting device of nickel-containing catalyst, comprise primary settling tank 2, accumulator tank 7, preposition magnetic filter 3, secondary settlement groove 4, circulation magnetic filter 6, circulating pump 5, capture slot 9, catch pump 8, as shown in Figure 1, wherein, accumulator tank 7 is connected primary settling tank 2 bottoms, and secondary settlement groove 4 is connected with primary settling tank 2 by preposition magnetic filter 3; Secondary settlement groove 4 bottoms are connected with circulation magnetic filter 6 by circulating pump 5, and secondary settlement groove 4 tops are connected with circulation magnetic filter 6 tops, form a loop between secondary settlement groove 4, circulating pump 5, circulation magnetic filter 6 threes; Circulation magnetic filter 6 tops are provided with passage; Preposition magnetic filter 3 all is connected with capture slot 9 with circulation magnetic filter 6 bottoms, and capture slot 9 bottoms are connected with accumulator tank 7 by catching pump 8.Be equipped with valve 10 on the interface channel of described each assembly.During use primary settling tank 2 is connected with hydrogenation still 1.
During use, the process that reclaims catalyst is as follows:
(1) after hydrogenation reaction finishes in the hydrogenation still, the xylitol hydride that generates is entered primary settling tank, carry out the sedimentation of catalyst, treat hydride light transmittance 〉=35% o'clock, open the valve between primary settling tank and the preposition magnetic filter, hydride is entered in the preposition magnetic filter; Open the valve between primary settling tank and the accumulator tank then, the catalyst of natural subsidence is entered in the accumulator tank;
(2) treat light transmittance 〉=50% o'clock of the hydride in the preposition magnetic filter, hydride is entered in the secondary settlement groove, in the secondary settlement groove, carry out the sedimentation of catalyst, treat hydride light transmittance 〉=65% o'clock, start circulating pump, through circulation magnetic filter circulating filtration hydride, carry out the secondary Separation of Solid and Liquid, to light transmittance 〉=90%, left standstill one hour, hydride enters subsequent processing by the passage on circulation magnetic filter top;
(3) treat that hydride is discharged fully after, the catalyst of preceding magnetic being put in filter, secondary settlement groove, the circulation magnetic filter with feed liquid (being xylose solution) washes to capture slot, restarts the seizure pump, and catalyst is squeezed into accumulator tank.
Promptly realized the thorough recovery of catalyst by above three steps.
