Detailed description of the invention
Presently in connection with accompanying drawing, the utility model is further described.These accompanying drawings are the schematic diagram of simplification and basic structure of the present utility model are described the most in a schematic way, and therefore it only shows the composition relevant with the utility model.
One energy-conservation zero-emission green type rectification training device as shown in Figure 1, including the raw material storage tank 3 being connected to rectifying column 2 stage casing by feed pump 1, rectifying column 2 hypomere connects reboiler 4, rectifying column 2 top pipeline connects has overhead condenser 5, overhead condenser 5 other end to be then connected with finished pot 6 pipeline.
This actual training device also includes being arranged on bottom rectifying column 2 and reboiler 4 and with bottom rectifying column 2 and the tower reactor discharging storage tank 7 that is connected of reboiler 4 bottom conduit, described tower reactor discharging tank bottom is by feed back pump 13 and raw material storage tank 3 pipeline connection.It is provided with intermediate storage tank 8 between overhead condenser 5 and finished pot 6 upper end, intermediate storage tank 8 is by reflux pump 9 and product flow meter 10 and finished pot 6 pipeline connection, and described reflux pump 9 and rectifying column 2 pipeline connection and the pipeline between rectifying column 3 and reflux pump 9 are provided with return flow meter 11.Sampler 14 it is provided with between finished pot 6 and metered flow meter 12.Intermediate storage tank 8, finished pot 6 and tower reactor discharging storage tank 7 top are respectively provided with and the blast pipe 15 of raw material storage tank 3 pipeline connection.
This actual training device, when operation, is broadly divided into three operational phases, now illustrates as a example by ethanol rectifying:
First stage, feed operation: first check for the liquid level of raw material storage tank 3, open raw material storage tank 3 top atmospheric valve, raw material storage tank 3 outlet at bottom valve and intermediate storage tank 8 atmospheric valve, whole actual training device is made to be in atmospheric pressure state, then start feed pump 1, fed to rectifying column 2 stage casing from raw material storage tank 3 by feed pump 1, and observe the liquid level change of reboiler 4.
Second stage, distillation operation: when reboiler 4 liquid level reaches the 1/3 of total scale, start the heater of reboiler 4, observe rectifying column 2 tower top and the temperature of tower reactor, treat that rectifying column 2 tower top temperature starts to raise, then opening the cooling water water intaking valve of overhead condenser 5, the distillate that rectifying produces enters intermediate storage tank 8；Continue to observe rectifying column 2 tower top and the temperature of tower reactor, control reboiler 4 liquid level less than the 2/3 of total scale by tower reactor bottom valve simultaneously；Then set up reflux operation, when the distillate liquid level of intermediate storage tank 8 reaches the 1/3 of total scale, start reflux pump 9, distillate in intermediate storage tank 8 passes back into rectifying column 2 top by reflux pump 9 and return flow meter 11, set up total reflux operation, and at any time distillate is carried out content analysis by return flow meter 11.After distillate content reaches Eligibility requirements, control the inlet amount of raw material storage tank 3, regulating calculation reflux ratio (return flow meter 11 and the ratio of product flow meter 10), by return flow meter 11 and product flow meter 10, under the effect of reflux pump 9, a distillate part in intermediate storage tank 8 is passed back into rectifying column 2, and a part then flows into finished pot 6 as finished fluid by pipeline, controls reboiler 4 liquid level simultaneously and must not exceed the 2/3. of total scale
Phase III, draw operation: close reboiler 4 heater, stop product flow meter 10 and work, stop backflow, intermediate storage tank 8 product is squeezed into finished pot 6 by reflux pump 9 and product flow meter 10, observe the liquid level of finished pot 6, substantially determine finished pot 6 yield.Then open finished pot 6 bottom valve, open the inlet valve of tower reactor discharging storage tank 7, finished fluid is injected tower reactor discharging storage tank 7 by metered flow meter 12.In the process, can be by the liquid level gauge of finished pot 6 and the quantum of output of metered flow meter 12 accurate calculation finished fluid.Can arrange a sampler 14 between finished pot 6 and metered flow meter 12, collecting sample measures finished fluid simultaneously.After all collections and statistics yield terminate, material in rectifying column 2, reboiler 4 being entered tower reactor discharging storage tank 7 in the lump, then opens feed back pump 13, the material in tower reactor discharging storage tank 7 is delivered to raw material storage tank 3, operating process terminates.
In the operating process in these three stage, the gas produced in intermediate storage tank 8, finished pot 6, tower reactor discharging storage tank 7 is all discharged in raw material storage tank 3 by blast pipe 15, it is ensured that each operational phase discharges without gas.And gas collector also can be installed in the bottom of the atmospheric valve of raw material storage tank 3, it is ensured that raw material storage tank 3 discharges without gas in fill process, stops the pollution to environment of the real training process.Raw material in raw material storage tank 3, after rectifying column 2 separates, is discharged into tower reactor discharging storage tank 7 after analyzing metering heat exchange again, and various materials in tower reactor discharging storage tank 7, finished fluid etc. can be transported to mixing in raw material storage tank 3 again, complete whole distillation procedure process.This set actual training device can be used afterwards to continue cycling through and to carry out rectifying training operation or technical ability match, raw material no consumption, reciprocating operation capable of circulation.And owing to the temperature of charge in rectifying column 2 tower reactor is higher, after discharge of materials enters tower reactor discharging storage tank 7, mix with finished fluid and squeeze into raw material storage tank 3 by feed back pump 13, also the temperature of raw material is mixed in can being effectively improved raw material storage tank 3, when continuous operation, the process of raw material preheating can be omitted, decrease the energy consumption during rectifying real training, reach the effect of energy-saving and environment friendly.
Above-mentioned embodiment is only for illustrating technology of the present utility model design and feature; its object is to allow person skilled in the art will appreciate that content of the present utility model and to be carried out; protection domain of the present utility model can not be limited with this; all equivalence changes made according to the utility model Spirit Essence or modification, all should contain in protection domain of the present utility model.
