Technical field
The invention belongs to technical field of chemical raw material production, and in particular to one kind can either recycle valuable spent acid, go back
Corresponding waste liquid can be recycled, meet environmental requirements, good in economic efficiency waste liquid recovery apparatus.
Background technique
Currently, highest content is acidic liquid in the waste liquid of industrial chemicals factory.Domestic manufacturer generally adopts
Spent acid is handled with the mode for neutralizing discharge, this needs to put into a large amount of fund to purchase a set of neutralizing device, and also to grow
Phase buys calcium oxide or compound alkali, to be neutralized to spent acid.After pH value as defined in reaching when waste liquid, it can discharge
Fall, later, it is also necessary to a large amount of useless waste residues of processing.The capital investment of this tradition waste acid treatment mode is big, and process is tedious, both
It thrown away valuable spent acid, wasted the secondary butyl ester in waste liquid, it is very uneconomical.In addition, traditional waste acid treatment mode
It is difficult to meet existing environmental requirement, bad adaptability.Therefore it can neither use, in order to solve chemical industry spent acid by national environmental protection convention
Fixed the problem of also not allowing direct emission, it is necessary to which existing devil liquor recovery technology is improved.
Summary of the invention
The present invention addresses the above problem, and valuable spent acid can either be recycled, corresponding give up also can be recycled by providing one kind
Liquid is met environmental requirements, good in economic efficiency waste liquid recovery apparatus.
The technical scheme adopted by the invention is that: the waste liquid recovery apparatus includes waste liquid receiving slit, geosyncline feeding line, ground
Slot discharging pipeline pumps out expects pipe line, waste liquid treatment tank, geosyncline and geosyncline pump, it is characterised in that: the feed inlet of the geosyncline passes through
Geosyncline feeding line is connected with waste liquid receiving slit, and the discharge port of geosyncline is connected by geosyncline discharging pipeline with the import that geosyncline pumps,
The outlet of geosyncline pump is then connected by pumping out expects pipe line with the feed inlet of waste liquid treatment tank.
Overflow weir, the entrance and industrial chemicals production equipment bottom of overflow weir one end are provided on the waste liquid receiving slit
Waste liquid outlet is connected, and the other end of overflow weir is provided with water outlet；The inside of overflow weir is additionally provided with overflow baffle, overflow baffle
Arrange that overflow baffle is between waste liquid outlet and water outlet vertically along the direction perpendicular with waste liquid overflow direction.To ensure
The stability of waste liquid overflow, the reliability of lifting device.
The waste liquid receiving slit can be set to multiple.Simultaneously to waste liquid caused by more industrial chemicals production equipments
It is recycled, improves recovery efficiency.
The geosyncline feeding line, geosyncline discharging and pump out on expects pipe line pipeline, are provided with control valve.In order to right
The control of process flow, and facilitate the maintenance of equipment.
Beneficial effects of the present invention: since the present invention passes through geosyncline feeding line and waste liquid receiving slit using geosyncline feed inlet
It is connected, geosyncline discharge port is connected by geosyncline discharging pipeline with geosyncline pump inlet, and geosyncline pump discharge is by pumping out expects pipe line and giving up
Liquid process tank feed inlet is connected；The entrance of the overflow weir one end being arranged on waste liquid receiving slit, with industrial chemicals production equipment bottom
Waste liquid outlet be connected, the other end of overflow weir is provided with water outlet；The inside of overflow weir is additionally provided with overflow baffle, overflow gear
Structure type of the plate between waste liquid outlet and water outlet, so its design is rationally, it is compact-sized, it can recycle valuable
Corresponding waste liquid also can be recycled in spent acid；It meets environmental requirements, reduces investment, increases economic efficiency.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the invention.
Number explanation in figure: 1 geosyncline, 2 geosyncline feeding lines, 3 waste liquid receiving slits, 4 geosynclines discharging pipeline, 5 geosynclines pump, 6
Pump out expects pipe line, 7 waste liquid treatment tanks.
Specific embodiment
The specific structure that the present invention will be described in detail with reference to the accompanying drawings.The waste liquid recovery apparatus includes waste liquid receiving slit 3, geosyncline into
Expects pipe line 2, geosyncline discharging pipeline 4 pump out expects pipe line 6, waste liquid treatment tank 7, geosyncline 1 and geosyncline pump 5, wherein the charging of geosyncline 1
Mouth is connected by geosyncline feeding line 2 with waste liquid receiving slit 3, and the discharge port of geosyncline 1 passes through geosyncline discharging pipeline 4 and geosyncline pump 5
Import be connected, geosyncline pump 5 outlet be then connected by pumping out expects pipe line 6 with the feed inlet of waste liquid treatment tank 7.Waste liquid receiving slit
