Summary of the invention
The purpose of this utility model is to provide a kind of normal pressure, rectification under vacuum actual training device of energy-conserving and environment-protective.
In order to achieve the above object, the technical solution of the utility model is: a kind of normal pressure, rectification under vacuum actual training device, comprise head tank, rectifying column, head tank is by the feeding inlet of feed pump and rectifying column, be provided with overhead condenser between rectifying column cat head discharging opening and the return tank, return tank communicates with the top of rectifying column by reflux pump; Return tank is connected with vavuum pump, also be connected with reboiler on the rectifying column, tower still discharge tank communicates with the discharging opening of rectifying column bottom, also connect product pump on the head tank, a branch of product pump outlet is communicated with head tank through behind the cooling water pipe of overhead condenser again, is communicated with head tank behind another branch's process tower still discharge tank of product pump outlet again.
Described reboiler is provided with electric energy meter.
Described overhead condenser is provided with water and can shows.
Be provided with vacuum buffer tank between described return tank and the vavuum pump.
Described overhead condenser is the biserial heat exchange of heat pipe.
Because the utility model also connects product pump on the one hand on head tank, a branch of product pump outlet is communicated with head tank through behind the cooling water pipe of overhead condenser again, carry out heat exchange so can make full use of overhead vapours and raw material, the temperature that enters the preceding raw material of rectifying column is improved, thereby can reduce the power consumption of reboiler, reach energy-conservation effect, also saved the consumption of cooling water simultaneously, reached the effect of not only energy-conservation but also water saving.On the other hand, because the utility model after connecting product pump on the head tank, is communicated with head tank behind another branch's process tower still discharge tank of product pump outlet again.Can allow raw material and tower still material carry out exchange heat so again, the temperature that enters the preceding raw material of rectifying column is improved, thereby can further reduce the power consumption of reboiler, and reduced the discharging of toxic gas, reach better effects of energy conservation and environmental protection.
Description of drawings
Fig. 1 is the schematic flow sheet of a kind of normal pressure of the present utility model, rectification under vacuum actual training device;
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
As shown in Figure 1, a kind of normal pressure of the present utility model, rectification under vacuum actual training device, comprise head tank 3, rectifying column 7, head tank 3 is by the feeding inlet of feed pump 4 with rectifying column 7, be provided with overhead condenser 14 between rectifying column 7 cat head discharging openings and the return tank 11, return tank 11 communicates with rectifying column 7 tops by reflux pump 9; Return tank 11 is connected with vavuum pump 13, also be connected with reboiler 6 on the rectifying column 7, tower still discharge tank 2 communicates with the discharging opening of rectifying column 7 bottoms, also connect product pump 1 on the head tank 3, a branch of product pump 1 outlet is communicated with head tank 3 through behind the cooling water pipe of overhead condenser 14 again, is communicated with head tank 3 behind another branch's process tower still discharge tank 2 of product pump 1 outlet again.
As shown in Figure 1, in order well to allow the operator understand the various data of real training, so that further calculating research is done in this test, described reboiler 6 is provided with electric energy meter 5, described overhead condenser 14 is provided with water energy table 10, data in showing by electric energy meter and water, can write down this utility model energy consumption and cooling water amount in actual use exactly, thereby the energy-saving and water-saving effect to this utility model has a quantitative evaluation, also can assess operator's operant level simultaneously.
Be provided with vacuum buffer tank 12 between described return tank 11 and the vavuum pump 13, guaranteed this actual training device safe effect in use.
Described overhead condenser 14 is the biserial heat exchange of heat pipe, and the steam that cat head is come out carries out sufficient heat exchange with raw material in condenser 14, further improve energy-conservation effect.
As shown in Figure 1, the utility model in use, check the liquid level of former storage tank 3, opening the atmospheric valve that raw material stores up 3 outlet valves and vacuum buffer tank 12 makes whole system be in atmospheric pressure state, start feed pump 4, reinforced to rectifying column 7, the liquid level of observation reboiler 6 changes, start electrical heating, when the liquid level of reboiler 6 reaches 1/3, observe cat head and tower still temperature, after waiting for that the rectifying column tower top temperature raises, open terminal valve and the product pump 1 and the valve that the overhead condenser cooling water pipe links to each other of product pump 1, start product pump 1, close the cooling water water intaking valve of overhead condenser.Make raw material enter the cooling water pipe of cat head biserial heat exchange of heat pipe and carry out heat exchange, enter rectifying in the rectifying column again after the temperature of raw material is improved, so just can reduce the power consumption of reboiler, reach energy-conservation effect with overhead vapours.The process of described tower still energy recovery operation is: after tower still material pot has material by the time, the valve that the terminal valve of opening product pump 1 and product pump 1 link to each other with tower still material pot cooling water pipe, start product pump 1, allow raw material and tower still material carry out exchange heat, after being improved, the temperature of raw material enters rectifying in the rectifying column again, equally also can reduce the power consumption of reboiler, reach energy-conservation effect.By water energy and electric power meter, the operator is obtained 1 kilogram of electric weight that product spends and the water yield is measured, not only can accurately estimate the energy-saving and water-saving effect of this utility model, and also can assess operator's operant level.
