Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
Seeing Fig. 1, is structural representation of the present utility model.A kind of sulphur ammonium of the utility model exhaust purifier 24, comprise clarifier, described clarifier bores section 2 forming closed cylindrical shell by top cylinder section 1 and bottom, and top is established and extended internally and the oviduct 3 expanded, and the osculum end of oviduct 3 connects cyclone dust collectors 23 by gas inlet pipe 4; Establish circular spray tube 5,6 and ring baffle 7 between oviduct 3 and clarifier barrel, ring baffle 7 is positioned at below circular spray tube 5,6, and circular spray tube 5,6 connects the Recycling Mother Solution pump discharge in sulphur ammonium production workshop section by mother liquor inlet tube 10; Discharge pipe 9 is established at clarifier top, and blow-down pipe 12 is established in bottom, middle cylinder is established overflow pipe 14, and blow-down pipe 12 is connected backflash 17 respectively with overflow pipe 14, and cone section 2 cylindrical shell establishes cleaning water pipe 18.
Described ring baffle 7 is arranged to inclined downward in clarifier, and be 5 ~ 15 ° with horizontal line angle, ring baffle 7 lowermost end is higher than oviduct 3 bottom surface 100 ~ 200mm.
Described annular spray line 5,6 is at least 2 roads, along the circumferential direction evenly arranges 2 row's spray holes bottom per pass annular spray line 5/6, and 2 row's spray holes are staggered.(as shown in Fig. 2-Fig. 3)
The sulphur ammonium tail gas that a kind of sulphur ammonium of the utility model tail gas device is used for adopting saturator method to produce thiamine process generation carries out purified treatment; Its operation principle is as follows:
The tail gas being entrained with a large amount of sulphur ammonium dust that cyclone dust collectors 23 are discharged is transported to clarifier top through gas inlet pipe 4, clarifier inner chamber is entered through oviduct 3, oviduct 3 internal diameter becomes ambassador's gas flow rate and sharply slows down, the suspension such as sulphur ammonium particle, dust contained in tail gas is under the effect of inertia, and major part to pour in the ammonium sulfate liquor bottom clarifier and dissolved;
Annular spray line 5,6 is established on clarifier top, and the spray mother liquor that circulating-pump outlet is drawn from sulphur ammonium production workshop section enters in annular spray line 5,6 through mother liquor inlet tube 10 and sprays downwards; Ring baffle 7 is provided with below annular spray line 5,6, the circular passage of tail gas through being formed between ring baffle 7 and oviduct 3 upwards flow and with spray mother liquor counter current contacting, the residue sulphur ammonium dust in tail gas is absorbed by mother liquor and dissolves and enter in the solution bottom clarifier; Tail gas after mother liquor spray is drawn through clarifier top discharge exhaust duct 9, enters air.
A part of suction compensation drag losses that clarifier produces exhaust gas flow is provided by regulating the height of discharge pipe 9.
The gas flow rate that tail gas stream exports through oviduct 9 is less than 1.5m/s, and determines oviduct 9 diameter accordingly, and oviduct 9 bottom surface is 350 ~ 500mm apart from ammonium sulfate liquor liquid level.
Bottom clarifier, ammonium sulfate liquor is regularly emptying, and uses clean water.
In the utility model, controlled the start and stop of annular spray line 5,6 sprinkling by valve 1, and will ensure that the spray mother liquor of drawing can not destroy the water balance in saturator, in order to avoid destroy the crystallization of sulphur ammonium, affect explained hereafter; Ring-like spray line 5,6 bottom opening mode, can ensure that mother liquor sprays completely; Ring baffle 7 is fixed on barrel by gusset 8 and also realizes being obliquely installed, ring baffle 7 can increase the resistance of gas flowing, both increased the time of contact of solution in tail gas and clarifier, the mother liquor that annular spray line 5,6 can be made again to spray fully absorbs remaining sulphur ammonium and dust in tail gas.
During normal operation, valve 3 15, valve 4 16 are opened, and discharged, enter backflash 17 after ammonium sulfate liquor is elevated to certain liquid bottom clarifier by overflow pipe 14; After running a period of time, along with the rising of sulphur ammonium concentration in ammonium sulfate liquor and increasing of dust, solid particulate matter progressively increases, and easily causes pipeline blockage, now opens valve 2 13, is discharged in backflash 17 by blow-down pipe 12 by the ammonium sulfate liquor in clarifier; Then open valve 5 19, clear water enters clarifier inside through cleaning water pipe 18 and cleans, and the gradient that bottom clarifier, the section of cone 2 is arranged can make tamper discharge clarifier rapidly, and enters backflash 17 through blow-down pipe 12.
Fig. 4 is that the utility model produces the layout drawing in thiamine process in saturator method.The capital equipment adopting saturator method to produce thiamine process comprises the pressure fan 20, air-heater 21, ebullated dryer 22 and the cyclone dust collectors 23 that connect successively, and ebullated dryer 22 is connected with conveying worm 26 in addition; After sulphur ammonium exhaust purifier 24 described in the utility model is arranged on cyclone dust collectors 23, its discharge pipe 9 connects exhaust blower 25 in addition.
