The present invention can segmentation be provided with a plurality of rectifying tower between main condenser E05 and water trap S07 as required, is used for removing the more solvent of waste water kind.
Well heater E01 is imitated in the present invention one, two shell sides of imitating well heater E02, triple effect heating chamber E03, preheater E04 and main condenser E05 all are connected with valve tube, and their negative pressure degree increases successively, by the orifice plate control negative pressure degree on the pipeline everywhere.
Concrete working process of the present invention is as follows:
Material flow: material arrives flasher S05 earlier, and process flash distillation wherein a part of solvent flashing is come out.The tube side circulation repeated to heat on most process triple effect recycle pump P02 was pumped into E04 after material came out from flasher S05 bottom, very little part is imitated fresh feed pump P03 through one and is arrived cold well E06 lower end, employing rises embrane method and therefrom rises to an effect heating chamber E01 upper end tube side, imitate from one and to imitate recycle pump P04 effect major part through one after well heater E01 comes out and be returned to one and imitate on the well heater E01 tube side, the lower end (suction inlet that promptly is equal to two effect recycle pump P05) of two effect well heater E02 is got back in little part tributary through valve C, top tube side falling liquid film pump circulation from two effect heating chamber E02, very little part tributary arrives the suction inlet that two of triple effect heating chamber E03 is imitated discharging pump P06 through valve D, imitating discharging pump P06 from two is exported to the triple effect heating chamber E03 tube side and forces to turn back and be recycled to the S03 of triple effect separate chamber and separate, isolated gas heats to preheater E04, and most of feed liquid to two is imitated discharging pump P06 circulation, become final dope after wherein having sub-fraction to pump through condensate pump P07, it promptly is waste material, the protein of recyclable utilization in this way, solvent, then recycled, the solvent that can not recycle then leads to method processing such as burning in this way.
Water vapor operational scheme after the material evaporation is: material is imitated through one and is partly flashed to water vapor in the heating chamber E01 tube side after the heat absorption, and from separating with an effect S01 top, separate chamber, gas is a part of to enter an effect well heater E01 shell side heating to thermocompressor SJ01 with hot steam, gas is then to the two shell sides heating of imitating well heater E02, and liquid is then imitated heating chamber E01 and from one and imitated the S01 of separate chamber bottom and imitate recycle pump P04 by one and be recycled to a tube side upper end of imitating heating chamber E01.In like manner, two imitate the isolated gas of the S02 of separate chamber then to the E03 shell side, and the isolated gas of the S03 of triple effect separate chamber is condensed into water to the heating of preheater E04 shell side from the isolated gas of the S04 of separate chamber to main condenser E05 shell side, deliver to water trap S07 again, until discharge.When the material among the present invention was heated in each heating chamber tube side, the liquid measure in each heating tube was identical, and became membranaceous dirty along inside pipe wall.
The steam condensate flow process: steam is imitated heating chamber E01 shell side process from one, being condensed into water after the heat release imitates from one and arrives two shell sides of imitating heating chamber E02 through K1 orifice plate dominant discharge after coming out in heating chamber E01 shell side bottom, imitate heating chamber E02 shell side bottom through water trap S06 from two again, the water vapor of separating from the water trap S06 triple effect heating chamber E03 shell side heating of flowing through from top, isolated water arrives water trap S07 from the bottom, the water of condensation that comes out in cold well E06 shell side bottom also is back to S06, the water of condensation of the shell side of triple effect heating chamber E03 is back to water trap S07, the water of condensation of preheater E04 shell side bottom also is back to S07, the water of condensation of main condenser E05 is back to water trap S07, from water trap S07, discharged again by condensate pump P08 effect, this is the sewage after handling, when solvent species is many, the water of condensation segmentation of coming out from E05 can be handled, handle with rectifying tower and separate solvent.For some special waste water, primary treatment possibly can't make the sewage after the processing reach emission standard fully, sewage after condensate pump P08 discharges can be entered once more another set of or continuous warp too much overlaps the treatment unit and handles, the a whole set of treatment unit of Chu Liing is identical with structure of the present invention once more, can be clean fully through repeatedly handling back sewage, well below emission standard, realize environment protection emission.
Also used vacuum system among the present invention, with the moving source of water-ring vacuum pump P09 conduct, the distribute vacuum tightness of each effect of a vacuum house steward is arranged, make each tube side and shell side produce negative pressuren zone, the malleation of shell side is big, and negative pressure is big more, temperature is low more, separate easily (in the separate chamber), E01-E05 negative pressure are controlled the negative pressure degree by orifice plate everywhere from small to large.
Following table is an experimental data of the present invention, and as can be seen from the table, original COD content is 91800mg/L, through the minimum 3200mg/L of dropping to of COD content in the water that discharges after the primary treatment.
The undeclared part of other that the present invention relates to is same as the prior art.
