After evaporating tower, light component is gradually concentrated in rectifying section, all condenses after leaving tower top into return tank, a part is produced as tower top
Product, another part are admitted in tower as phegma.And after heavy constituent is concentrated in profit reduction and reserving section, a part is used as bottom product,
It is a part of then sent back in tower after reboiler heats, a certain amount of steam air-flow continuously risen is provided for distillation operation.Rectifying column
The balance of finance, credits and materials of operation is material balance, vapor liquid equilibrium and heat balance.Rectifying column operation is during control tower balance, and one
As control is inlet amount, reflux ratio, the size of heat, cooling capacity.
For reboiler often with rectifying column combined application, reboiler is mounted on rectifier bottoms, passes through reboiler heating tower bottom and steams
The liquid for evaporating kettle vaporizes its part and becomes upflowing vapor, is rectifying section, stripping section and the column plate vehicle repair major of rectifying column
Heat and mass provides required heat.There is no tower reactor heat supply just without rising steam, it is whole without overhead condensation just without phegma
A distillation process just cannot achieve.Most of reboiler is shell-and-tube heat exchanger, and boiling process can occur in shell side,
It can occur in tube side, heat medium generallys use steam, is also possible to liquid, gas of heat-carrying etc..
In distillation process, the heat medium steam in Steam reboiler can condense generation condensate liquid, and reboiler liquid level is logical
It is controlled frequently with regulating valve.Steam fluctuation will lead to tower bottom liquid temperature fluctuation in reboiler, and the heat balance of rectifying column will be by
To influence, and heat balance is material balance and the basis that vapor liquid equilibrium is achieved.
Therefore, how to solve the problems of the above-mentioned prior art becomes the direction of field technical staff effort.
