The feeding tank is connected with an evaporation inlet of the evaporator through a circulating pump, and discharged liquid flows back the feeding tank. An evaporation outlet of the evaporator is respectively connected with the feed liquid flash tank, the condensation water flash tank and the condenser, the feed liquid flash tank is communicated with the feeding tank, the condensation water flash tank is connected with the heating water groove, and the heating water groove is communicated with a hot water inlet of the evaporator through a hot water pump. The discharged liquid of the condenser is connected with the cooling tank, and a condensation water tank is communicated with a cold water inlet of the condenser through a condensation water pump. The teaching test system provides a set of complete and small-size process and control system of the evaporation and concentration equipment for students to enable the students to self complete a technological process of the evaporation and concentration equipment of feed liquid and engineering design of an automatic control system and master basic contents, steps and methods of actual system engineering design.
Description
Technical field
The utility model belongs to experiment device for teaching, relates to the process control teaching, the process control teaching experiment system of especially a kind of evaporation, concentrator.
Background technology
At present in the automated teaching equipment of higher education and Vocational, what generally use is the device of analog automatization equipment, such as garage robotization, automatic production line, simulation process control system (DCS system) teaching equipment is also arranged, purpose be exactly allow the student with the knowwhy acquired in the experimental facilities checking of getting on, by programming, on line and test, consolidate the knowwhy of acquiring, improve the practical operative ability of oneself, strengthen following workmanship.But in the automation engineering implementation process of reality, these technical ability are a part wherein.Students remains and can't understand and grasp fully the engineering design of the robotization industry be engaged in future, action etc.
So in teaching, particularly the graduating student must take exercise through actual engineering design, improves their actual engineering design ability, makes them can be fit to oneself work after graduation at once.

Description of drawings
Fig. 1 is the utility model system architecture synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment utility model is described in further detail, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
The process control teaching experiment system of a kind of evaporation, concentrator, comprise evaporator 1, feed liquid flash tank 11, head tank 9, condensed water flash tank 2, condenser 3, heating water tank 7, cooling water tank 6, head tank is by the evaporation import of ebullator 10 connection evaporators, and fluid is back in the head tank; The secondary steam outlet of evaporator is communicated with respectively feed liquid flash tank, condensed water flash tank and condenser, and the feed liquid flash tank is communicated with head tank, and the condensed water flash tank connects heating water tank, and this heating water tank is communicated with the hot water inlet of evaporator by heat-exchanger pump 8; The fluid of condenser connects cooling water tank, and condensation water tank is by the cooling water inlet of condensate pump 5 connection condensers, and in addition, condenser also connects a vacuum pump 4.
Present embodiment has omitted electric control system.
This experimental system can be carried out following process teaching:
1, medium flow process
Feed liquid is stored in the head tank, and feed liquid is delivered in the evaporator through the entrance of ebullator, and ebullator makes feed liquid circulating and evaporating in evaporator, and a part of feed liquid is diverted to the feed liquid flash tank from circulating-pump outlet, and feed liquid is returned in the head tank of feed liquid through after the flash distillation.
2, steam flow
The steam of vapo(u)rization system mainly is secondary steam, and the flash steam that the secondary steam of evaporator, condensed water flash tank and the flash distillation of feed liquid flash tank produce comes together in that to enter condenser behind the secondary steam pipe cool solidifying.
3, hot water flow process
Hot water is the thermal source of evaporator, hot water heats in heating water tank, the heating element that hot water after the heating is delivered to evaporator through heat-exchanger pump is inner, hot water is through carrying out after the heat interchange cool solidifying with the outside feed liquid of heating element, cool solidifying water enters the condensed water flash tank, and the condensate water after the flash distillation returns heating water tank.
4, condensate water flow process
The condensate water that evaporator produces enters the condensed water flash tank and carries out flash distillation, and the condensate water after the flash distillation enters head tank.
5, cooling water flow path
Chilled water is delivered to cool condenser heating element surface through cooling-water pump, the secondary steam of cooling heating element inside, and the chilled water after the heat interchange returns cooling water tank.
6, vacuum flow process
Vacuum pump extracts the gas in the cool condenser heating element, makes inner and coupled secondary steam pipe and the evaporator tank body of cool condenser heating element be negative pressure, and feed liquid is evaporated being lower than in 100 ℃ the situation like this.
