Description
Technical field
The utility model relates to rectifier unit, is specifically related to a kind of hypothermia distillation device.
Background technology
In modern society, people are the recycling of attaching importance to environmental protection and the energy more and more, but in the chemical industry distillation operation, the gas phase of rectifying column generally uses cooling water by the top gaseous phase condensation, heat in gas phase is recycled cooling water and takes away, and then with cooling blower by the thermal release in recirculated cooling water in atmosphere, thereby reduce the temperature of recirculated water.Yet contain amount of heat in the rectifying column gaseous stream, as adopt conventional method, this heat will all indirectly enter in atmosphere, and for these heats can be discharged into to atmosphere, also will consume a certain amount of electric energy, this has caused huge energy waste, therefore needs a kind of device that can recycle.
The utility model content
The purpose of this utility model is to provide a kind of hypothermia distillation device, and equipment is simple, and the heat in rectifying column, again recycling, is reached to the effect that circulates in utilization, saves the energy, reduces costs.
hypothermia distillation device described in the utility model, comprise rectifying column, the rectifying column top connects the condenser top by pipeline, rectifier connects the condenser lower end by pipeline, the condenser lower end arranges the distillate mouth, condenser top one side connects absorption heat pump by pipeline, condenser one side connects absorption heat pump top by pipeline, the absorption heat pump bottom is connected with reboiler one side by pipeline, absorption heat pump bottom one side is connected with the reboiler top by pipeline, the reboiler top arranges charging aperture, reboiler opposite side bottom is connected with the rectifying column low side by pipeline, reboiler opposite side top is connected with the rectifying column middle part by pipeline, the setting of reboiler low side distillates still liquid mouth.
The utility model is only applicable to cryogenic rectification.
the rectifying in rectifying column of the utility model material produces a large amount of heat, heat enters condenser from rectifying column by pipeline, the waste liquid that produces distillates by the distillate mouth, the high-temperature water that produces enters absorption heat pump by pipeline, the cooling water that absorption heat pump produces enters condenser and continues cooling, the high-temperature water that absorption heat pump produces enters reboiler material is heated, the water at low temperature that produces is got back to absorption heat pump by pipeline, simultaneously, still liquid flows out by still liquid mouth, simultaneously, heat in reboiler is connected to form a circulation with bottom and the middle part of rectifying column respectively by pipeline.
Compared with prior art, the utlity model has following beneficial effect:
The utility model hypothermia distillation device, equipment is simple, and the heat in rectifying column, again recycling, is reached to the effect that circulates in utilization, saves the energy, reduces costs.
