Abstract
The utility model relates to a novel neopentyl glycol distillation cooling device. The novel neopentyl glycol distillation cooling device comprises a rectifying column, a discharge pipe, a heat exchanger, a transfer pipe, a refrigerating machine, a water tank, a collecting tank and a pump. According to the novel neopentyl glycol distillation cooling device, neopentyl glycol is distilled through the rectifying column and then introduced into the heat exchanger through the discharge pipe, the neopentyl glycol and cold water exchange heat in the heat exchanger, and the neopentyl glycol is cooled from a gaseous state into a liquid state and then introduced into the collecting tank through the transfer pipe to be collected.
Description
Technical field
The utility model relates to refrigerating field, specifically a kind of novel neopentyl glycol rectifying cooling device.
Background technology
In the manufacture of saturated polyester resin, poly-Ammonia resin, powdery paints etc.; neopentyl glycol is attached to peltate protection is provided in polyester resin strand; make resin there is good chemical stability, corrosion resistance, resistance to ag(e)ing and heat endurance, be widely used in the industries such as automobile, household electrical appliances, ornament materials.Therefore in industrial production, the neopentyl glycol that distillation is collected in waste liquid is very important, and this collects with regard to needing a cooling device that the neopentyl glycol after distillation is cooled to liquid state, for later separation step is prepared.
Summary of the invention
For the problems referred to above, the utility model provides a kind of novel neopentyl glycol rectifying cooling device.
A kind of novel neopentyl glycol rectifying cooling device described in the utility model, comprises rectifying column, discharge nozzle, heat exchanger, conduit, refrigeration machine, tank, collecting tank, pump.Rectifying column is connected with heat exchanger by discharge nozzle; Heat exchanger is connected with refrigeration machine by conduit; Refrigeration machine is connected with tank; Pump is connected with conduit; Heat exchanger is connected with collecting tank.Neopentyl glycol is after rectifying column distillation, in discharge nozzle delivery heat exchanger, water in tank passes in heat exchanger after refrigeration machine refrigeration, and heat exchange occurs in heat exchanger for neopentyl glycol and cold water, and neopentyl glycol is cooled to liquid by collecting in conduit importing collecting tank by gaseous state.
The beneficial effects of the utility model are: equipment is simple, easy to operate, safe and reliable.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, the 1st, rectifying column, the 2nd, discharge nozzle, the 3rd, heat exchanger, the 4th, conduit, the 5th, refrigeration machine, the 6th, tank, the 7th, collecting tank, the 8th, pump.
The specific embodiment
As shown in the figure, rectifying column is connected with heat exchanger by discharge nozzle; Heat exchanger is connected with refrigeration machine by conduit; Refrigeration machine is connected with tank; Pump is connected with conduit; Heat exchanger is connected with collecting tank.Open pump, water in tank is extracted in refrigeration machine, after water refrigeration, pass in heat exchanger, neopentyl glycol is after rectifying column distillation, in discharge nozzle delivery heat exchanger, there is heat exchange in neopentyl glycol and cold water, neopentyl glycol is cooled to liquid by collecting in conduit importing collecting tank by gaseous state in heat exchanger.
