Abstract
The utility model relates to a condensation flux system of a rectification tower. The condensation flux system comprises a purifying tower (1), a pressurizing tower (2) and a lift pump (3), wherein a heat exchanger (5) is arranged above the pressurizing tower (2), a material outlet below the purifying tower (1) is connected with an inlet of the lift pump (3), an outlet of the lift pump (3) is connected with a shell pass inlet of the heat exchanger (5), and the shell pass outlet of the heat exchanger (5) is connected with a material inlet of the purifying tower (1). The condensation flux system is characterized in that a steam outlet of the pressurizing tower (2) is communicated with a tube pass top inlet of the heat exchanger (5), and a tube pass bottom outlet of the heat exchanger (5) is connected with recirculation pipe inlets of the purifying tower (1) and the pressurizing tower (2) through pipelines, and is higher than recirculating liquid inlet pipes of the purifying tower (1) and the pressurizing tower (2). The system is low in energy consumption and low in equipment cost.
Description
Technical field
The utility model relates to a kind of rectifying column condensing reflux system.
Background technology
Need to use purifying column and pressurizing tower in the material distillation process, in the prior art, after the condensation of pressurizing tower cat head high temperature and high pressure steam process heat exchanger, liquid is collected into surge tank, be promoted to purifying column and pressurizing tower respectively by the condensing reflux pump then, this system carries in the reflux course needs the condensing reflux pump to promote, and it is higher to consume energy.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of rectifying column condensing reflux system low and that equipment cost is low that consumes energy is provided.
The purpose of this utility model is achieved in that a kind of rectifying column condensing reflux system, it comprises purifying column, pressurizing tower and elevator pump, described pressurizing tower top is provided with heat exchanger, the below material outlet of described purifying column links to each other with the elevator pump import, described elevator pump outlet links to each other with the heat exchanger shell pass import, described heat exchanger 5 shell sides outlet links to each other with the purifying column material inlet, described pressurizing tower steam (vapor) outlet is connected with heat exchanger tube side top inlet, described heat exchanger tube side outlet at bottom links to each other with the return duct import of purifying column and pressurizing tower respectively by pipeline, and the tube side outlet at bottom of described heat exchanger is higher than the phegma inlet tube of purifying column and pressurizing tower respectively.
Compared with prior art, the beneficial effects of the utility model are:
Produce high temperature and high pressure steam in the utility model pressurizing tower, high temperature and high pressure steam enters the tube side of pressurizing tower cat head heat exchanger, the shell side of pressurizing tower cat head heat exchanger delivered to material in the purifying column by elevator pump at the bottom of the purifying column by certain flow, carry out heat exchange, be cooled to liquid through the material in the pressurizing tower heat exchanger tube side after the heat exchange, be partly refluxed to pressurizing tower again, be back to purifying column by potential difference another part.
Compared with prior art, save surge tank and condensing reflux pump, both saved energy consumption and reduced equipment investment.
