0.5 ~ 0.8 times.
Compared with prior art, this utility model technology has advantages below：
（1）The temperature of raw material acid, makes the acid vapor for distilling out obtain sufficient heat exchange in by reducing three-level condensing tube,
Become the higher gas-liquid mixture of content liquid, improve the yield of concentrated acid.
（2）Heating chamber energy consumption reduces by more than 50%, while doing coolant with cold raw material concentrated sulphuric acid, has both saved cooling water
Consumption, reduces equipment investment and power consumption, turn avoid using the potential safety hazard and high-temperature acid of the relatively low cooling water of boiling point to storage
The infringement of sour equipment.
（3）Due to having carried out special inner and outer pipes Proportionality design in three-level condensing tube, inner tube had both been reduced because of upper and lower side
The potential safety hazard that the temperature difference is big and brings, increases dense, dilute sulfuric acid separated space again so that concentrated acid product purity is high and stablize, and
Pressure reduction of the concentrated acid to pipeline between inner and outer pipes is reduced, plugging is difficult.
（4）Due to devising evacuated tube at scum pipe top, heating chamber lower port so that pressure is all the time in whole equipment
Balance and stability, reduces the potential safety hazards such as booster, plugging that equipment endogenous cause of ill high pressure belt comes.
（5）The sulphuric acid purity obtained by the purification of this utility model sulfuric acid refining unit is high, and foreign metal ion content reaches
Ppb levels.
