Abstract
The utility model relates to a device for discharging tar wastewater back to a tower of the ammonia still tower. The device comprises a tar discharging pit, a wastewater collecting tank and a wastewater reflux pump, wherein the tar discharging pit is connected with the ammonia still tower through a pipeline, and an inclined steel plate with a smooth surface is fixedly arranged in the tar discharging pit. Ammonia still wastewater flows into the wastewater collecting tank through an overflow weir plate arranged at the side wall of the tar discharging pit, and the ammonia still wastewater in the wastewater collecting tank is pumped to the ammonia still tower through the wastewater reflux pump. The device has the advantages that the device treats the ammonia still wastewater so that the ammonia still wastewater conforms to the provisions of environmental protection indexes; the tar discharging pit plays a role of cooling the ammonia still wastewater, so that the tar is cooled to be conveniently cleared; the steel plate with the smooth surface is obliquely arranged, so that the tar on the steel plate is conveniently cleared; and the wastewater reflux pump collects the wastewater collected in the wastewater collecting tank and discharges the wastewater into the bottom of the ammonia still tower, and then the wastewater is discharged to an environmental-protection work zone through a wastewater treatment process.
Description
Technical field
The utility model relates to the put-focus oily waste water of a kind of ammonia still and returns tower apparatus.
Background technology
During the put-focus oil of ammonia still, a small amount of tar is discharged with distilled ammonia wastewater, this part waste water design directly enters in the ammoniacal liquor system, last entering into again carried out a large amount of steam and the alkali of ammonia still process waste in the ammonia still, increase the load of ammonia still, waste water reenters in the ammonia still and enters the environment protection sewage treatment unit with distilled ammonia wastewater, and reaching can normal convenient and swift discharging distilled ammonia wastewater, guarantees that again the processing water yield of ammonia still is with steam and the alkali of cutting the waste.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model provides the put-focus oily waste water of a kind of ammonia still and returns tower apparatus, and the tar in the recycling distilled ammonia wastewater makes the distilled ammonia wastewater environmental protection index up to specification.
For achieving the above object, the utility model is achieved through the following technical solutions:
The put-focus oily waste water of a kind of ammonia still returns tower apparatus, comprise put-focus oily hole, waste water collection tank, return of waste water pump, put-focus oil hole is connected with ammonia still by pipeline, put-focus oil is fixed with ganoid inclined steel plate in the hole, distilled ammonia wastewater flows into waste water collection tank by the overflow weir that is located at put-focus oil hole sidewall, and the distilled ammonia wastewater in the waste water collection tank is drawn back ammonia still by the return of waste water pump.
Described steel plate and oblique angle, bottom, put-focus oil hole are the 25-75 degree.
Compared with prior art, the beneficial effects of the utility model are:
Process distilled ammonia wastewater, can reduce a large amount of steam and the alkali of ammonia still process waste, the effect in put-focus oil hole is the cooling distilled ammonia wastewater, is convenient to cleaning after making the tar cooling; Being obliquely installed of smooth surface steel plate, the glutinous tar thereon of easy cleaning; The return of waste water pump is collected the waste water of collecting in the waste water collection tank, and again returns at the bottom of the ammonia still, then together is discharged into the environmental protection working district by waste water treatment process.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: the 3-steel plate 4-waste water collection tank 5-return of waste water pump 6-overflow weir of the put-focus oil of 1-ammonia still 2-hole.
Embodiment
Below in conjunction with Figure of description the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1, the put-focus oily waste water of a kind of ammonia still returns tower apparatus, comprise put-focus oil hole 2, waste water collection tank 4, return of waste water pump 5, put-focus oil hole 2 is connected with ammonia still 1 by pipeline, be fixed with ganoid inclined steel plate 3 in the put-focus oil hole 2, distilled ammonia wastewater flows into waste water collection tank 4 by the overflow weir 6 that is located at put-focus oil hole 2 sidewalls, and the distilled ammonia wastewater in the waste water collection tank 4 is drawn back ammonia still 1 by return of waste water pump 5.
Described steel plate 3 is the 25-75 degree with oblique angle, 2 bottom, put-focus oil hole.
Embodiment:
Increase a waste water collection tank 4 near the put-focus oil hole 2 that is connected with ammonia still 1, distilled ammonia wastewater can be in the put-focus oil hole 2 by overflow weir 6 overflow flow in the waste water collection tank 4 also can be by pipe flow will to waste water collection tank 4; Overflow weir 6 is lower than the sidewall height in put-focus oil hole 2.
Waste water collection tank 4 increases a return of waste water pump 5, by this pump the waste water of waste water collection tank 4 interior collections is returned 1 end of ammonia still again, then together is discharged into the environmental protection working district by waste water treatment process.
The utility model is processed distilled ammonia wastewater, can reduce a large amount of steam and the alkali of ammonia still process waste, and the effect in put-focus oil hole is the cooling distilled ammonia wastewater, is convenient to cleaning after making the tar cooling; Being obliquely installed of smooth surface steel plate, the glutinous tar thereon of easy cleaning; The return of waste water pump is collected the waste water of collecting in the waste water collection tank, and again returns at the bottom of the ammonia still, then together is discharged into the environmental protection working district by waste water treatment process.
Claims (2)
