The specific embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated, as shown in Figure 1, treating apparatus of the present invention comprises body lotion forecooler VK, body lotion cooler BK, crystallizer K, sulfuric acid absorption device WT and off-gas condenser SK, wherein body lotion forecooler VK is three grades, be respectively VK1, VK2 and VK3, body lotion cooler BK also is three grades, be respectively BK1, BK2 and BK3, crystallizer K is a level Four, be respectively K1, K2, K3 and K4, body lotion enters through the body lotion inlet of body lotion forecooler VK, then through tertiary treatment, boil-off gas is carried out cooling processing from first boil-off gas inlet that the outlet of first boil-off gas enters the body lotion cooler, the liquid that body lotion forecooler VK handles enters crystallizer K through liquid outlet, and after 4 grades of crystallization treatment, send into salt and starch sealing groove, the boil-off gas outlet of crystallizer connects the boil-off gas inlet that is connected to off-gas condenser SK1 and SK2 respectively, and in off-gas condenser SK1 and SK2 by concentrated sulfuric acid absorption condensation, the concentrated sulfuric acid cycles through circulating pump UP and sulfuric acid heat exchanger WT is recycling, concentration reduces the back and gets rid of, cooling water feeds in sulfuric acid heat exchanger WT1 and the WT2, reduces the temperature of the concentrated sulfuric acid that passes through, and recycles.
Body lotion has obtained final cooling in the level Four crystallizer of flowing through, in order to keep the suspended state of body lotion in crystallizer, and can deliver to the K4 level to them from the K1 level, and air in certain amount is blown into equably by the distributing pipe of crystallizer bottom, and this distributing pipe forms circulus in the crystallizer bottom.Brine pump SP is transported to thickener to the salt solution mix thing that comes out from crystallizer K4, is condensed into certain density saltcake and then enters centrifuge, the be separated fusion bucket that enters subsequent processing or sell as product of saltcake in centrifuge.Overflow mother liquor in the thickener returns bath of liquid condenser BK1 and makes cooling medium behind deaerating tank.Isolated filtrate is converged with crystallizer K4 export pipeline behind deaerating tank in the centrifuge, delivers to thickener again by brine pump SP, and the circulation sedimentation is filtered.
The evaporation vapour that body lotion flash distillations at different levels produce in forecooler VK1-3 enters the mother liquor condensation that bath of liquid condenser BK1-3 is overflowed back by thickener; The evaporation vapour that produces among the crystallizer K1-4 enters waste condensator SK, and by the sulfuric acid adsorption condensing, sulfuric acid liquid send be cooled water cooling cooling of condensed heat transfer fluid device WT to recycle through circulating pump UP, constantly replenishes the concentrated sulfuric acid simultaneously, and diluted sulfuric acid is discharged continuously; The incoagulable gas of system is extracted the further condensation of water that is cooled respectively out through second steam jet pump ED1, ED2 in the second condenser HK1, HK2, the gas that is not condensed is got rid of by vavuum pump VP again, its main technologic parameters is sulfuric acid concentration 65-98%, crystallization temperature 12-16 ℃, steam pressure 0.45MPa, cooling water temperature 30-32 ℃.
