Abstract
The utility model provides a treating system for a nanofiltration concentrated liquor of landfill leachate. The treating system comprises an evaporator, a compressor and a gas-liquid separator which are connected with each other, wherein the evaporator is also connected with a steam trap and is provided with a steam inlet; the treating system can evaporate moisture in the nanofiltration concentrated liquor, so as to separate the moisture from pollutants; and residual pollutants are solidified or recharged after being put into a furnace for combustion or being sprayed onto high-temperature furnace dust. Therefore, the nanofiltration concentrated liquor of the landfill leachate is treated with low energy consumption.
Description
Technical field
The utility model relates to the refuse treatment field, relates in particular to a kind of percolate nanofiltration dope treatment system.
Background technology
Garbage loading embeading and garbage power are the dual modes to refuse treatment, yet in refuse landfill and refuse-burning plant, can produce a large amount of percolates, and this is a kind of waste water that contains high pollution thing, high-enriched organics; As do not deal carefully with; Can to around water body and soil cause severe contamination, at present this percolate is adopted the method processing of " biochemistry+membrane filtration " more, yet in membrane filtration processes, has 30% nanofiltration dope to be difficult to biochemical degradation; If turn back in the original system; The meeting accumulation is more and more many, and this is to perplex the difficult problem that percolate is handled always, also is a urgent problem.
The utility model content
The utility model provides a kind of percolate nanofiltration dope treatment system, and the nanofiltration dope that solves percolate 30% in the prior art is because of containing the problem that the big organism of quite a lot of quantity molecular weight is difficult to biochemical degradation.
A kind of percolate nanofiltration dope treatment system; Interconnective vaporizer, compressor and gas-liquid separator between comprising in twos; Said vaporizer also is connected with trap and is provided with the steam-in; Start when the percolate nanofiltration dope of said compressor in the heating chamber of said vaporizer is heated to boiling, compression comes the secondary steam of flash-pot.
Further, said vaporizer also is provided with the noncondensable gas tapping equipment.
Further, said noncondensable gas tapping equipment also is connected with scavenging tower.
Further, said compressor is a multistage centrifugal compressor.
Further, said percolate nanofiltration dope treatment unit also comprises first and second interchanger that is used for waste heat recovery to the heating chamber of accomplishing liquid and lime set.
The beneficial effect of the utility model is:
The percolate nanofiltration dope treatment system that the utility model adopts can steam moisture content from the nanofiltration dope, pollutent remains in the nanofiltration dope; The inorganics salt is all non-volatile in the nanofiltration dope, the larger molecular organics volatility far beyond water a little less than, only the part small organic molecule can get into water vapor; Be lime set with steam coagulation finally, this lime set biodegradability is good, and nanofiltration dope amount is greatly reduced; Can go into finally that stove burns or spray to solidify on the high temperature ashes or recharge, solve in the prior art percolate nanofiltration dope is difficult to disposal concerns, the utility model treatment system is in utilizing the secondary steam normal course of operation simultaneously; Except the power consumption of compressor and pump; Extra heat need be provided, and, further reduce energy consumption through to lime set and the recycling of accomplishing fluid residual heat.
The utility model accompanying drawing
Fig. 1 is the percolate nanofiltration dope treatment system of an embodiment of the utility model.
Embodiment
Below the contrast accompanying drawing further specifies the utility model:
A kind of percolate nanofiltration dope treatment system, as shown in Figure 1, comprise interconnective between any two vaporizer 1, gas-liquid separator 2 and compressor 3, said vaporizer 1 also is connected with trap 4 and is provided with steam-in 9.Said steam-in 9 is as the inlet of giving birth to steam and secondary steam; Said trap 4 is used for being discharged into lime set pond 5 with giving birth to the lime set that forms after steam and the secondary steam heat exchange; Said vaporizer 1 also has noncondensable gas tapping equipment 12; Said noncondensable gas tapping equipment 12 is connected with scavenging tower 6 through pipeline, and the noncondensable gas that said vaporizer 1 is produced gets in the said scavenging tower 6 through said noncondensable gas tapping equipment 12 and discharges after the purification, and is free from environmental pollution.Said gas-liquid separator 2 separates the secondary steam and completion liquid that generates in the said vaporizer 1; The liquid of completion relief outlet 10 and refluxing opening 11 are arranged at said gas-liquid separator 2 bottoms; Said completion liquid relief outlet and said refluxing opening 11 are used for said gas-liquid separator 2 and get rid of with about 95% ratio with about 5% respectively and accomplish liquid, do not have when keeping this percolate nanofiltration dope treatment unit works better to move under the situation of heat credit input.When being heated to boiling, the nanofiltration solution of said compressor 3 in said vaporizer 1 starts; Said compressor 3 sucks the secondary steam in the said gas-liquid separator 2 and compression; And the secondary steam after will compressing through described steam-in 9 is sent back in the said vaporizer 1; Said compressor 3 exits are connected with said lime set pond 5 pipelines, can spray into an amount of lime set to reduce the superheating temperature of compression back secondary steam, and said compressor 3 is a multistage centrifugal compressor.
Be the better utilised preheating; Save energy in the present embodiment, also is being provided with first interchanger 7 and second interchanger 8 on percolate nanofiltration dope pond 13 and the feed pipe that said vaporizer 1 is connected; Lime set is through said first interchanger 7; Accomplish liquid through said second interchanger 8, carry out heat exchange, realize the recovery of waste heat with percolate nanofiltration dope on the feed pipe.
Percolate nanofiltration dope: the dope that nanofiltration produced during percolate was handled, be difficult to by biochemical degradation, that is to say the object that the present invention is directed to processing.
Give birth to steam: from the saturation steam of boiler house, used living steam pressure is 0.2MPa in the embodiment of the invention.
Secondary steam: the steam that liquid produced in the evaporative process in the vaporizer, described liquid is meant percolate nanofiltration dope in the present invention.
Accomplish liquid: the liquid concentrator that percolate nanofiltration dope is discharged from gas-liquid separator behind pervaporation.
Lime set: mainly refer to the liquid that living steam and secondary steam heat release condensation form.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the utility model person of ordinary skill in the field; Under the prerequisite that does not break away from the utility model design; Can also make some being equal to substitutes or obvious modification, and performance or purposes are identical, all should be regarded as belonging to the protection domain of the utility model.
