Description
Technical field
The utility model relates to a kind of alcohol ketone device deperoxidation reactive system
Background technology
Alcohol ketone device adopts the manufacturing process of hexalin, pimelinketone (alcohol ketone) mixture in the process of deperoxidation reaction, produces hexanodioic acid chromium precipitation, stops up the rectifying tower tower tray of subsequent production workshop section, needs regularly to utilize sodium hydroxide to carry out alkali cleaning to this throw out.Alkali cleaning then must be installed the shut-down material returned, has a strong impact on the cycle of operation, hexanaphthene unit consumption, the plant energy consumption of device; And the alkali cleaning operation has certain technology risk (alkali lye is burnt).During the ordinary production, the transformation efficiency of deperoxidation reaction must be controlled between 68～82%, because the deperoxidation reaction conversion ratio is more high, the hexanodioic acid chromium of generation precipitation is more many, and alkali wash period is more short.About 30% reaction is not carried out, and influences the alcohol ketone unit consumption.
The utility model content
The purpose of this utility model provides a kind of alcohol ketone device deperoxidation reactive system, utilize the hexanodioic acid chromium in the sedimentation deperoxidation reaction mass, reduce the distillation tower tower tray and stop up probability, prolong alkali wash period, increase the deperoxidation reaction time, improve transformation efficiency.
Alcohol ketone device deperoxidation reactive system described in the utility model comprises: deperoxidation reactor, slurry tank, strainer, pump, valve and pipeline; The deperoxidation reactor is a horizontal container, and inside is provided with four chambers, and each chamber is furnished with an agitator, and entrance is connected with dehydration tower by filtering net, is positioned at the container bottom outlet and is connected with the V6 valve by the V5 valve; The V6 valve is connected with the entrance of slurry tank by V2 valve, V4 valve, and simultaneously, the V6 valve is connected with pump A by V7 valve, strainer A, is connected with pump B by V8 valve, filter B; The outlet that is positioned at container ends is connected with the entrance of slurry tank by the V4 valve; An outlet that is positioned at the slurry tank downside connects respectively at V7 valve, V8 valve inlet by the V1 valve, and the opposite side outlet is discharged by the V3 valve; Being positioned at the slurry tank top exit is connected with dehydration tower; Pump A, pump B are connected with the V11 valve by V13 valve, V10 valve respectively, and the V11 valve is connected with distillation tower by filtering net, V12 valve.
The deperoxidation reactor; Horizontal container, inside have four chambers, and each chamber is furnished with an agitator.
At the deperoxidation reactor outlet slurry tank is installed, during ordinary production, the material that leaves the deperoxidation reaction enters slurry tank, finishes a part of remaining deperoxidation reaction in jar, improves transformation efficiency.Slurry tank top adds precipitating inhibitor (the hot fat of phosphoric acid), prevents from entering the hexanodioic acid chromium sedimentation in the material of distillation tower, stops up tower tray; Hexanodioic acid chromium sedimentation in the sedimentation deperoxidation material of slurry tank bottom reduces the hexanodioic acid chromium content in the material.Squeeze into distillation tower with pump and separate alcohol ketone, hexanaphthene through sedimentation, the heavy material of handling of resistance.Hexanodioic acid chromium precipitation is more in slurry tank, can onlinely isolate, clear up slurry tank.
Realized to stop and to have removed a large amount of hexanodioic acid chromium precipitation, reduced the distillation tower tower tray and stop up probability, prolonged alkali wash period to 5 month.
Increase deperoxidation reaction time 10 minutes, on average improve deperoxidation reaction conversion ratio 1.5%, can reduce alcohol ketone unit consumption 2kg/t, annually calculate by 52500 tons of alcohol ketone products, 105 tons of the hexanaphthenes of can saving material are amounted to about 1,000,000 yuan of Renminbi.
