Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described in detail.
A kind of converter valve cooling system embodiment:
1) converter valve cooling system composition structure:
As shown in Figure 1, a kind of converter valve cooling system comprises: valve cold loop and deionized water branch road, valve cold loop by intercooling cycle pump 1., 10. 2. outdoor heat exchanger form with valve, deionized water props up route main branch road and the parallel connection of emergency bypass is formed, main branch road connect successively flow control valve 4., deionization interchanger 3., ion-exchanger service valve 6., filter 8. with filter service valve 9..The emergency bypass of deionized water is identical with main branch structure.
3. the main branch road of deionized water and the upstream of emergency bypass arrange deionization flow sensor, and 7. the downstream of ion-exchanger and ion-exchanger for subsequent use is also respectively equipped with conductivity meter.
2) operation principle of converter valve cooling system:
After inner cold water is due to heat temperature raising in converter valve, through valve cold loop, inner cold water is cooled.Cooled part inner cold water flows into deionized water branch road by the road.Deionization flow sensor in deionized water branch road can carry out Real-Time Monitoring to the flow of the inner cold water flowed in deionizer, is treated the flow of deionized inner cold water by Flux Valve Control.When the main branch road of deionized water normally works, the inner cold water flowed in deionized water branch road filters out the ion needing to remove by the deionization interchanger of the main branch road of deionized water, then through filter again from the downstream part of the main branch road of deionized water through piping, again flow into valve cooling system, if the main branch road of deionized water breaks down, then inner cold water is filtered by deionized water emergency bypass.
Filter is mainly used in filtering the resin dropped from deionization interchanger, prevents its blocking pipe.
Conductivity meter detects the conductivity value in the inner cold water after deionization, observes it whether meet the requirement of converter valve to inner cold water conductivity.If do not satisfied condition, then again by control flow check adjustable valve, deionization process is carried out to inner cold water.
Ion-exchanger service valve and filter service valve, realize not affecting under the running status that valve cooling system normally works, realize on-bne repair safeguard ion-exchanger and filter.
Flow control valve in this enforcement adopts electric proportional-regulation valve, and when in inner cold water during conductivity >=A1, it is maximum that flow control valve is adjusted to the inner cold water flow flowed in deionizer; As conductivity >=A2 in inner cold water, it is minimum that flow control valve is adjusted to the inner cold water flow flowed in deionizer; When inner cold water conductivity is between A1 and A2, flow control valve carries out real-time regulating and controlling according to the size of inner cold water conductivity value.
In this enforcement, conductivity meter is arranged on the exit of ion-exchanger, in actual applications according to the actual state of engineering, conductivity meter can be arranged on other positions of valve cooling system equally, can clear, the conductivity of observing inner cold water after deionization easily.
This enforcement intermediate ion interchanger adopts the mode of two tank parallel connection, when mainly in order to ensure that a branch road breaks down wherein, deionizer operationally can continuous firing, but in actual applications, if less demanding, a branch road only can be set, if engine request is higher, many emergency bypasses can be set.
In the present embodiment, deionization branch circuit parallel connection is in the valve cold loop of valve cooling system, and as other execution modes, deionization branch road also can be connected in parallel on the optional position in loop.
Above embodiment is only for example and not limitation to technical scheme of the present invention; with reference to the present embodiment to any amendment of the present invention in spirit and spirit with equivalent to replace; as changed the model, configuration mode etc. of a device, be all encompassed in protection scope of the present invention.
