Background technology
One of unit operations is widely applied in rectifying in the field such as chemical industry, pharmacy, and experiment rectifier unit is the micro of commercial plant.During rectifying, boiling in rectifying bottle and the steam that goes out, after rectifying column, condenser, reflux ratio controller, heavy constituent (i.e. phegma) is back to rectifying column, and light component (i.e. Produced Liquid) connects liquid device through extraction, and inflow extraction connects in liquid bottle.How extraction connects the function of liquid device, directly has influence on the effect of rectifying.
In distillation process, the part of first extraction, namely heats up in a steamer head part, and its boiling point is too low; The part of last extraction, namely heats up in a steamer portion, then boiling point is too high, and these two parts are not the components of normal need, only has mid portion to be only the light component of normal need.Therefore, need its constituent content of frequent sample analysis, to determine to heat up in a steamer head part, mid portion, heat up in a steamer the switching node of portion.With sampled functions, it is one of requirement connecing liquid device.
When the amount of rectifying is comparatively large, exceed extraction when connecing the capacity of liquid bottle, need more changing-over liquid bottle.In the time of replacement operation, need the Produced Liquid of extraction to keep in.If the capacity connecing liquid device itself is inadequate, then need a part of Produced Liquid overflow to connect liquid bottle to for subsequent use.With relief function, it is the requirement two connecing liquid device.
In addition, in distillation process, if atmospheric operation, connecing liquid device or connecing liquid bottle needs and atmosphere, namely ventilates, in order to avoid produce pressure, affects normally carrying out of rectifying.If open pore connecing on liquid bottle, often cause the volatilization of Produced Liquid.Adding breather pipe connecing on liquid device, is the best method addressed this problem.Therefore, with ventilatory function, be the requirement three connecing liquid device.
Traditional rectifying experiment, with connecing liquid device, often only has above-mentioned Section 3 function, lacks first and second two functions, samples, more the operation of changing-over liquid bottle is very inconvenient, and easily causes the unrestrained of Produced Liquid.
