About air face of detached in the right way has a problem to want to consult everybody, that is about detached tower choose, why be to use tower of dual class rectify commonly? is tower of only course rectify accorded with asked? Consulted an expert for unlock doubt specially, got is as follows replying.
This and the principle with detached air have a canal, detached tower meets ordinary air undertake in air of lieutenant general issueing a tower the first time rectification, its depart becomes sky of oxygen boosting fluid and purity nitrogen; Going up next the tower below tower lieutenant general offers the stock that come farther rectify, get the oxygen of tall purity and nitrogen. And will go up, the ligament that next towers cooperate cheek by jowl is condensation evaporator, it is to use the pressure nitrogen of next towers to heat go up the liquid oxygen of the tower, make liquid oxygen evaporates to enrage nitrogen at the same time by condensation. Although use tower of only course rectify to also can be made,take product of oxygen, nitrogen, but can make respectively only take among them a kind high pure product, and old recovery rate of loss of oxygen, nitrogen is poor, specific power consumption is tall, regarding detached air as equipment is not perfect, because this is actual,use less. And if using tower of dual class rectify, make the product has higher recovery rate not only, can make at the same time take oxygen and nitrogen two kinds of double expensive products, product specific power consumption is low.
