Description

Distillating evaporator

The utility model relates to a kind of distillation vaporising device, and the medicine of further saying so, chemical industry laboratory are used for solution concentration and solvent reclaims.

Traditional distillation vaporising device is to be combined by cucurbit and condenser pipe; Using this device is disposable solution to be added in the cucurbit, directly distills evaporation to the cucurbit heating, finishes up to reclaiming, just can stop heat supply, the solution heated time is long, can not produce continuously, because the static pressure of solution easily produces superheating phenomenon, cause that the thermal sensitivity solute is rotten; The cucurbit disengagement area is little, and efficient is low.

Adopt the thin-film distillation vaporising device to distill evaporation,, do not have approved product on the market, need self-control, and need decompression, can only use the gas heat supply though shortened the heated time of solution.

The purpose of this utility model provides a kind of continuous heat supply, the tubular distillation vaporising device of feed flow successively, the heating surface area of this device evaporation tube is big, high efficiency, the solution heated time is short, does not produce superheating phenomenon, but normal pressure work, liquid or gas heat supply all can, and can be by adjusting gradient, heat supply temperature and the liquid supply rate of heating tube, and obtain the recovery speed of different solution concentration degree and solvent.This device also can carry out solution concentration and solvent repeatedly and reclaim, and is particularly suitable for medicine, the use of chemical industry laboratory.

The purpose of this utility model can reach by following measures: the utility model includes: heater, fluid supplier, heating tube, condenser pipe, gatherer and recover; By heating tube and tube connector it is communicated with between heater and the heating tube.An evaporation tube, a steam channel and 5-10 vapor-liquid separation pipe are arranged in heating tube; Evaporation tube is positioned at the Lower Half of heating tube, and its end is little bend pipe or intubate, stretches out outside the heating tube, is communicated with the fluid supplier that is positioned at heating tube one end top, and the other end is little straight tube, stretches out outside the heating tube, is communicated with gatherer by tube connector; Steam channel is positioned at the top of heating tube, and its end is little bend pipe, stretches out outside the heating tube, communicates with the condenser pipe that is positioned at the heating tube top, and the other end is a cecum, is enclosed in the heating tube; The vapor-liquid separation pipe is between evaporation tube and steam channel, and its lower port is communicated with evaporation tube, and upper port is communicated with steam channel.The other end of condenser pipe is communicated with recover by tube connector.

The utility model is rational in infrastructure, and superheating phenomenon does not take place energy continuous heat supply feed flow, and the evaporation tube disengagement area is big, and high efficiency is saved the energy, reduces cost.

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1 is the integrality figure of distillation vaporising device;

Fig. 2, Fig. 3 are the I-I sectional drawing and the II-II sectional drawing of heating tube in this device;

Fig. 4 is III-III view of Fig. 3;

As shown in Figure 1: this device comprises heater (1), fluid supplier (16), heating tube (7), condenser pipe (18), gatherer (14) and recover (15); Electrical socket (2) is arranged on the heater (1), be communicated with by heating tube (3) and tube connector (5) between the heat inlet (6) of heater (1) and heating tube (7), be communicated with by tube connector (12) between the heat-return port (11) of heating tube (7) and the heater (1); Heating tube (3) is erected in above the heater (1), in its upper port a safety valve (4) is housed.An evaporation tube (8), a steam channel (9) and 5-10 vapor-liquid separation pipe (10) are arranged in heating tube (7), and they are straight tube shape; Evaporation tube (8) is positioned at the Lower Half of heating tube (7), its end has made the little bend pipe of fluid-tight effect, stretch out outside the heating tube (7), be communicated with the fluid supplier (16) that is positioned at heating tube (7) one ends top, the other end makes little straight tube, stretch out outside the heating tube (7), be communicated with gatherer (14) by tube connector (13); Steam channel (9) is positioned at the top of heating tube (7), and its end makes little bend pipe, stretches out outside the heating tube (7), communicates with the condenser pipe (18) that is positioned at heating tube (7) top, and the other end is a cecum, is enclosed in the heating tube (7); Vapor-liquid separation pipe (10) is positioned between evaporation tube (8) and the steam channel (9), and its lower port is communicated with evaporation tube (8), and upper port is communicated with steam channel (9).The other end of condenser pipe (18) is communicated with recover (15) by tube connector (19).On the pipe of fluid supplier (16), the valve of a control liquid supply rate size is housed.
