For realizing above-mentioned utility model purpose; The technical scheme that the utility model adopts is the continuous alkaline cleaner of a kind of isopropyl benzene; Mainly comprise liquid caustic soda groove, raw material tank, settling bath, one-level alkaline bath and secondary alkaline bath, said liquid caustic soda groove joins with one-level alkaline bath and secondary alkaline bath respectively, and said raw material tank and one-level alkaline bath join; Said one-level alkaline bath and secondary alkaline bath join, and said secondary alkaline bath and settling bath join.
Said liquid caustic soda groove joins with one-level alkaline bath and secondary alkaline bath respectively through the liquid caustic soda pump.
Said raw material tank joins through feedstock pump and one-level alkaline bath.
The outlet at bottom of said one-level alkaline bath is connected to one-level alkali cleaning pump, is connected to the one-level mixing tank on the said one-level alkali cleaning pump, and said one-level mixing tank joins with the import of one-level alkaline bath again.
The outlet at bottom of said secondary alkaline bath is connected to secondary alkali cleaning pump, is connected to the secondary mixing tank on the said secondary alkali cleaning pump, and said secondary mixing tank joins with the import of secondary alkaline bath again.
Beneficial effect: 1. adopt the method for pump around circuit, make isopropyl benzene and liquid caustic soda thorough mixing, effectively remove acidic impurities and volatile phenol in the isopropyl benzene; Isopropyl benzene and liquid caustic soda continuously into and out of, make to produce to be in continuous regime, enlarged production capacity; 3. isopropyl benzene and liquid caustic soda have mixing tank to mix, better effects if when contacting.

Embodiment
Below in conjunction with specific embodiment, further illustrate the utility model, present embodiment is being to implement under the prerequisite with the utility model technical scheme, should understand these embodiment only be used to the utility model is described and be not used in the restriction the utility model scope.
As shown in Figure 1, the continuous alkaline cleaner of a kind of isopropyl benzene mainly comprises liquid caustic soda groove 1, is provided with liquidometer and blow-down pipe; Raw material tank 2 is provided with liquidometer and blow-down pipe; Settling bath 3 is provided with liquidometer and blow-down pipe, and the opening for feed position is provided with baffle plate 12 and bottom groove; One-level alkaline bath 4 is provided with liquidometer and opening for feed inwardly projecting orifice, and hugging length reaches more than 6 meters; Secondary alkaline bath 5 is provided with liquidometer and opening for feed inwardly projecting orifice, and hugging length reaches more than 6 meters.
Wherein raw material tank 2, and outlet at bottom is connected with 7 imports of isopropyl benzene pump; 7 outlets of isopropyl benzene pump are connected with 8 imports of one-level alkali cleaning pump.Liquid caustic soda groove 1, outlet at bottom are connected with 8 imports of one-level alkali cleaning pump, 9 imports of secondary alkali cleaning pump respectively.One-level alkaline bath 4, bottom are provided with two outlets, and an outlet is connected with 8 imports of one-level alkali cleaning pump; Salkali waste is got rid of in another outlet.8 outlets of one-level alkali cleaning pump are connected with one-level mixing tank 10, are connected with 4 imports of one-level alkaline bath again.One-level alkaline bath 4 top exits are connected with 5 imports of secondary alkali cleaning pump.Secondary alkaline bath 5, bottom are provided with two outlets, and an outlet is connected with 9 imports of secondary alkali cleaning pump; Salkali waste is got rid of in another outlet.9 outlets of secondary alkali cleaning pump are connected with secondary mixing tank 11, are connected with 5 imports of secondary alkaline bath again.Secondary alkaline bath 5 top exits are connected with settling bath 3 imports.
Principle of work: raw material isopropyl benzene and liquid caustic soda get into one-level alkali cleaning pump simultaneously, through mixing tank, in the one-level alkaline bath, precipitate at last again.Post precipitation, lower floor is the liquid caustic soda layer, the upper strata is the isopropyl benzene oil reservoir.A liquid caustic soda layer part recycles through one-level alkali cleaning pump again, and an order part is discharged as salkali waste.The isopropyl benzene layer extrudes at the top, gets into the secondary caustic washing system.The secondary caustic washing system is identical with one-level caustic washing system principle, and the isopropyl benzene that the secondary alkali cleaning extrudes is suitable post precipitation in settling bath, discharges a small amount of salkali waste, and qualified isopropyl benzene is for use.
