Embodiment
As shown in Figure 1, 2, 3, recirculated water control system of the present invention is comprised of two parts, and one is the PLC controller that comprises the temperature detecting function module, has consisted of the main core control section of whole water circulation system.Another part is the entity that the heating rod 6, water pump, electromagnetically operated valve, water pipe, pipe joint of the liquid-level switch that contains various models, temperature sensor 4, band protection sheath etc. consists of circulating water line critical piece and stainless steel water tank.
Described PLC control core part writes PLC with the PLC control program that writes in advance.Again each holding wires such as various start stop switches, diverter switch, anti-overflow liquid-level switch 3, waterproof dry combustion method liquid-level switch 5, temperature sensor 4 are connected on 24 volts of power supplys of direct current and PLC controller.The wiring such as relay of the auxiliary relay of the associated solenoid valve of control output end, control water pump simultaneously connect, and are included on 24 volts of power supplys of direct current and PLC controller.Through to each switch, limit sensors, each battery valve and water pump action response fast accurate, carrying out to temperature sensor accuracy, the programme controlled accuracy that signal correction guarantees signal after program debugging.
The entity part of described stainless steel water tank can accomplish can also complete fast when needed the actions such as draining, moisturizing to the fast ripe intensification of circulation.It is to realize like this that recirculated water is rapidly heated.After pressing start button, work water pump 8 of recirculated water master starts, recirculated water advances joint 15 through two electromagnetically operated valves 11 and 12 water to fuel cell pile successively, going out joint 16 from fuel cell pile water again through fuel cell pile 17 flows out, the following water that flows to radiator 20 by pipeline advances joint 18, go out joint 19 through radiator 20 from radiator water and flow out, then flow back to 1 li of inlet water tank through the backwater joint 2-2 that pipeline flows to water tank.Current are very short from the time that main work water pump 8 is opened to reflow tank 1, and this moment, powerful heating rod 6 was started working.This time period is set during by field adjustable PLC program.The temperature of time recirculated water of taking a few minutes in the lower situation of temperature in winter can raise up rapidly after through powerful heating rod 6 heating.This recirculated water control system also has automatic protection functions.When heat cycles water, when the liquid-level switch 5 of anti-dry was reported to the police, the water circulation heat temperature raising stopped.Associated solenoid valve 10 on the moisturizing water route is opened at once, and and then moisturizing water pump 9 starts, and the working barrel in circulation is appointed right maintenance work, flows to water tank 1 through the associated pipe in circulation.In like manner, reported to the police by spilling water liquid-level switch 3 when moisturizing proceeds to when soon overflowing water tank, immediately close the electromagnetically operated valve 10 on two water pumps and moisturizing water route.At needs more during draining, electrically heated rod 6 is not worked in addition; Start change taps after, the water pump of circulation rotates, water route prime battery valve switches to and changes water one side, the water route is no longer through the battery valve of rear class.Recirculated water just can directly be discharged to sewer through drainage pipe fast without pile, radiator thus, realizes substituting the artificial loaded down with trivial details water conservancy project work that changes.
Example 1:
The recirculated water control system that utilization is controlled based on PLC is the work that is rapidly heated of the recirculated water before the short heap test of one 20 joint.
Detailed process is as follows: first fuel cell pile 17 is installed to existing Proton Exchange Membrane Fuel Cells test platform commonly used.The pipeline of water circulation according to " Fig. 3. circulation waterway is controlled schematic diagram " connect, the pipeline in other flow field is received in test total system by existing way.After circulation is opened, main work water pump 8 work of recirculated water, the signal of the liquid-level switch 3 of anti-overflow, waterproof dry combustion method liquid-level switch 5 is all in normal non-alarm condition.Recirculated water 11 and 12 two electromagnetically operated valves of flowing through successively flow to pile water by pipeline and advance in joint 15, enter fuel cell pile 17 and go out joint 16 from pile water and flow out; Recirculated water flows to radiator water through water pipe again and advances in joint 18, enters radiator 20 and goes out joint 19 outflows from radiator water; Recirculated water flows to the backwater joint 2-2 of water tank upper circulation water again through water pipe, flow back in stainless steel water tank 1; Recirculated water in the water tank water below water tank again goes out pipe joint 7 outflows, flow back into the final formation water circulation of work water pump 8 through pipeline.Recirculated water flows out to the time of getting back in stainless steel water tank 1 from work water pump 8 and only has more than 10 second, and the time one that sets in the PLC program arrives, and starts the heating rod 6 energising heating to band protection sheath at once.Because the temperature of electrically heated heating rod 6 power than systemic circulation water gets a promotion very soon.About 40 liters of water in cyclic water tank, the short heap of 20 is if the heat pile intensification that produces by spontaneous working reaction is very slow.Winter, temperature was low when only having 5 ~ 6 degrees centigrade, 40 liters of recirculated waters be raised to 60 degrees centigrade nearly 4 hours.60 degrees centigrade is the comparatively ideal working temperature point of conventional proton exchange film fuel cell electric piling work operating ratio.Adopted afterwards after this scheme the heating rod of 3 kilowatts to use a few minutes just can be raised to 60 degrees centigrade.Compare with existing test platform, the stand-by period of heating up when detecting pile is shortened in the utilization of this system greatly, has reduced to test the time used and also shortened total cycle of pile production simultaneously, reduces production costs.
Example 2:
Proton exchanging film fuel battery test platform utilizes the water in the recirculated water control system replacing water tank of controlling based on PLC in the situation that system stops testing.
Detailed process is as follows: at first start to start the draining push-button switch, electromagnetically operated valve 11 TURP is changed to the water route of opposite side, that is: the follow-up pipeline 13 of electromagnetically operated valve used of draining.The water route is no longer through the battery valve 12 of rear class and fuel cell pile 17, the radiator 20 of back, so recirculated water just can directly be discharged to sewer through drainage pipe fast, realizes automatic Quick drainage.Press stop button after drained water, then start the work that the moisturizing button carries out past water tank 1 moisturizing.Electromagnetically operated valve 10 and 12 got electric work before this, electromagnetically operated valve 10 switches to the state of conducting, electromagnetically operated valve 12 switches to the moisturizing joint 2-1 of opposite side pipeline UNICOM water tank upper circulation water, is then that the water of deionized water source goes out work water pump 8 work in working barrel 9 and circulation pipeline.The moisturizing water route forms thus, deionized water source goes out working barrel 9 by water and pumps, link by the road the water inlet of work water pump 8 through electromagnetically operated valve 10, flow to again the moisturizing joint 2-1 of water tank upper circulation water by pipeline after work water pump 8 pumps flow through successively two electromagnetically operated valves 11 and 12, cover at last stainless steel water tank 1.The moisturizing work of water tank 1 can be accomplished automatically to stop, and has signal feedback to quit work to the device that PLC triggers relevant moisturizing work thereby the water level in water tank 1 is elevated to the liquid-level switch 3 of encountering anti-overflow.
But above-mentioned embodiment is exemplary, is to be this patent to be comprised the restriction of scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do anyly be equal to change or modify, all fall into the scope that this patent comprises.
