Description
Technical field
The present invention relates to a kind of waste liquid purification retracting device, especially relates to high-efficiency desulfurization waste liquid and carries salt retracting device.
Background technology
In coke-oven plant taking ammonia as alkali source, adopt in the desulfurization of binuclear cobalt phthalocyanine ammonium sulfonate (PDS) catalyst, in its doctor solution, salt content can progressively increase, when salt content reaches 250g/L when above, desulfuration efficiency can reduce. Therefore in sweetening process, must outwards discharge part doctor solution (desulfurization waste liquor), supplement again in addition the new ammoniacal liquor of part, salt content in doctor solution is controlled in regulation requirement, thereby guarantee desulfurized effect. And contain ammonium thiocyanate, ATS (Ammonium thiosulphate), ammonium sulfate etc. in the desulfurization waste liquor of discharge, and if material had both been wasted in the not treated directly externally discharge of desulfurization waste liquor, again can serious environment pollution. Therefore in prior art, all can process desulfurization waste liquor, the one, can from desulfurization waste liquor, reclaim the important industrial chemicals such as ammoniacal liquor, ammonium hydrogen sulfate, ammonium thiocyanate, can eliminate again the pollution of desulfurization waste liquor to environment. Also can make the salt content in desulfurization waste liquor reduce simultaneously, make desulfurization waste liquor become new ammoniacal liquor doctor solution and reenter in desulphurization system and utilize, reduce new ammoniacal liquor and supplement, reduce processing cost, turn waste into wealth, both can improve Business Economic Benefit, can reduce again environmental pollution.
At present, the method and system of desulfurization waste liquor processing is also more, as vacuum evaporating crystalization is put forward salt system, burned acid making system, preparing sulfuric acid by oxidizing ammonium system etc. In the above system, desulfurization waste liquor generally will pass through all multiple operation such as double-stage filtering, activated carbon decolorizing, vacuum evaporation, and its double-stage filtering is an important operating procedure, and what the quality of filter effect directly affected desulfurization waste liquor puies forward salt and ammoniacal liquor organic efficiency. And the filtration of existing desulfurization waste liquor is mainly with coke and micropore ceramic tube double-stage filtering, the subject matter that this two-stage filtering device exists is: one-level coke filtering device was processed after a period of time, after the indissoluble degradation product of coke in adsorption desulfurize waste liquid, easily be deposited on coke surface and inner formation passivation, block filtering micropore, thereby reduce suction-operated and filter effect, coke filtering device cannot carry out backwash regeneration, must regularly carry out coke replacing, increase processing cost; Because of coke filtration exist equipment huge, take up an area that space is large, maintenance difficulty, thereby can not backwash and make the usefulness performance of short, shortcoming seriously the restricted whole desalination system such as treatment effect is not good enough of the cycle of operation. Secondary micropore ceramic tube filter is a kind of Novel high-efficiency filtering technique, at present also many for the micropore ceramic tube filter of industrial wastes, but existing micropore ceramic tube filter is mostly waste liquid to be introduced in earthenware, in managing, to pipe, ooze out again, the disadvantage of this mode is that a large amount of difficult degradation things is gathered in pipe, easily results in blockage, and pipe inside and outside differential pressure is large, the filtration that causes screen pipe explosion to have a strong impact on separation of flow waste liquid is oozed out, and reduces filter effect. Next is that existing micropore pottery filter is mostly upper and lower two-way fixing, complicated structure, and processing, installation and maintenance inconvenience, cost is higher.
Summary of the invention
For existing problem in above-mentioned prior art, the invention provides one simple structure compactness is housed, to manufacture convenient for installation and maintenancely, the desulfurization waste liquor of the better micropore ceramic filtering apparatus of filter effect is carried salt retracting device.
The technical scheme that the technical problem to be solved in the present invention is taked is, described high-efficiency desulfurization waste liquid is carried salt retracting device and is comprised two-stage filtering device, described two-stage filtering device is interconnected and is formed by two micropore ceramic filtering apparatus, described micropore ceramic filtering apparatus comprises tank body and end socket, tank body lower part is provided with inlet and sewage draining exit, tank body top is provided with liquid outlet and exhaust outlet, tank body top is provided with the backwash mouth being communicated with liquid outlet, in tank body, be provided with supporting disk, on supporting disk, be arranged at intervals with fluid hole, the supporting disk bottom surface interval relative at fluid hole is fixedly installed stop collar, stop collar and micropore ceramic tube upper end external diameter are closely matchedly connected, micropore ceramic tube lower end is connected with sealing gasket by convex-concave structure, sealing gasket is arranged on pressing plate, micropore ceramic tube upper end communicates with tank inner chamber by fluid hole, on supporting disk corresponding to micropore ceramic tube upper end, be provided with the fixed mount of riding, described ride to be provided with between frame and pressing plate micropore ceramic tube can be to hanging like interval and be fixed on the pull bar on supporting disk.
Innovation one of the present invention is existing desulfurization waste liquor to be carried to the two-stage filtering device being made up of coke and earthenware in salt retracting device be designed to the two-stage filtering device being mutually in series by two cover micropore ceramics block filtering devices, both can reduce and take up room, simplify filter plant, extend the cycle of operation, save construction cost, can improve again desulfurization waste liquor filter effect; The 2nd, further microporous ceramic filter is carried out to significant improvement, fixedly changing former micropore ceramic tube two ends into upper end supporting disk by gripper shoe fixes, makes micropore ceramic tube lower end to be hanging like with the frame of riding, both can prevent that indissoluble degradation product was gathered in pipe, and be conducive to the filtration of doctor solution and be convenient to backwash.
The present invention compared with prior art has the following advantages:
1, specific filtration resistance surface area increases, and separate unit filtration treatment amount improves, and has reduced processing cost,
2, desulfurization waste liquor goes out in entering outward, and pipe inside and outside differential pressure is little, and screen pipe bears pressure and increases, applied widely,
3, pollution discharge capability is strong, and backwashing time is short and the backwash water yield is few,
4, compact conformation, take up room littlely, processing, installation and maintenance are convenient,
5, durability is strong, long service life.
