Embodiment
To be described in further detail the utility model embodiment below.
Phenol ammonia sewage disposal dual-purpose distillation system of the present utility model, its preferably embodiment be:
Comprise solvent stripper, solvent stripper reboiler, solvent recovery tower, solvent recovery tower reboiler, extract preheater;
The material pipe of extract enters described solvent recovery tower after the heat transfer tube of described extract preheater, described solvent recuperation column overhead discharge nozzle is successively through the heat transfer tube of described solvent stripper reboiler and the heat transfer tube of extract preheater, and the heat transfer tube of described solvent recovery tower reboiler is connected with heating steam pipe.
The top of described solvent stripper is provided with the outlet of solvent stripper recycling design, and middle part is provided with extract remainder import, and bottom is provided with rare phenol water out.
The bottom of described solvent recovery tower is provided with crude phenols outlet.
Phenol ammonia sewage disposal dual-purpose distillation system of the present utility model, overcomes the shortcoming in existing phenol ammonia sewage disposal technology, and technological design rationally, good product quality, energy consumption are low, less investment, production cost are low, convenient operation controls.
In the utility model, the discharging of molten solvent recovery tower tower top as solvent stripper reboiler thermal source, final recycling design, economizer energy consumption.Solvent recovery tower as solvent stripper reboiler thermal source eject material after heat exchange, temperature reduces to 97-100 DEG C, then through extract preheater, after preheating extract, temperature reduces to 88-90 DEG C, solvent recovery tower eject material condensation after recycling design.
Advantage of the present utility model is:
1. the utility model changes in existing technique, the problem that solvent stripper adopts external steam to waste energy as thermal source, solvent recovery tower is only needed to adopt external steam heating in process of the present utility model, and solvent stripper reboiler does not need external steam as thermal source, therefore, while energy-conservation, production cost is again reduced.
2. the utility model uses solvent recuperation column overhead discharging heat of condensation as heat energy by adopting solvent stripper reboiler, form " economic benefits and social benefits " rectifying, sufficiently and reasonably make use of the energy of solvent recuperation column overhead discharging, make the more existing technique of the energy consumption of whole device reduce 48%, really accomplish energy-efficient.
3. native system sufficiently and reasonably make use of the energy of solvent recuperation column overhead discharging, make the more existing technique of the energy consumption of whole device reduce 48%, really accomplishes energy-efficient; The utility model technique advantages of simple, manufacture and keep in repair easily, capacity usage ratio is high, and energy consumption reduces significantly, reduces investment and production cost, has broad application prospects.
Specific embodiment:
Carry out describing for process 130t/h phenol ammonia sewage per hour.
As shown in Figure 1, solvent stripper 9, solvent stripper reboiler 11, solvent recovery tower 10, solvent recovery tower reboiler 12, solvent recuperation tower top condenser, extract preheater 13 etc. are comprised.
Extract 1 is preheating to about 90 DEG C through extract preheater 13, solvent recovery tower 10 recycling design is entered through solvent recovery tower charging 8 after extract preheating, the solvent recuperation column overhead discharging 4 that tower top steams containing light constituents such as a large amount of solvent and a small amount of phenol reduces to 97-100 DEG C through solvent stripper reboiler 11 temperature, be solvent recovery tower recycling design 6 again after extract preheater 13, tower top temperature control 110-120 DEG C, solvent recovery tower reboiler 12 has the saturated heating steam 14 of 2.5MPa to provide heat, need to consume steam 5.9t/h, bottom product is crude phenols 5.Extract remainder 2 enters solvent stripper 9, and a small amount of solvent stripper recycling design 7 is steamed by tower top, and the rare phenol water 3 after extraction stripping is discharged by the bottom of tower, and solvent stripper reboiler 11 heat is provided by solvent recuperation column overhead discharging 4.
130t/h phenol ammonia sewage per hour is processed equally by existing technique, because solvent recuperation column overhead discharging steam is all used as solvent stripper reboiler thermal source, save solvent stripper reboiler heating steam 5.6t/h, therefore only need solvent recovery tower reboiler to consume steam 5.9t/h, through more known, technique of the present utility model, than existing technique saving steam consumption per hour 5.6t/h, accounts for 48% of native system process steam consumption.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
