With reference to Fig. 1, the present invention is the control system that a kind of diesel residual heat utilizes, comprise diesel cylinder sleeve 6 and be connected in cooling water swelling water tank 15, heat exchanger 3 and the cooling water circulating pump 5 in circulation loop with diesel cylinder sleeve 6, be connected with heat exchanger 3 the thermal source swelling water tank 4, sea water desalinating unit 1 and the heat-source Cycles pump 2 that are provided with and conspire to create desalination of sea water loop.
The control system that this diesel residual heat utilizes drives the cooling water through diesel cylinder sleeve 6 to circulate in cooling circuit by cooling water circulating pump 5, and by heat exchanger 3, diesel residual heat is replaced to desalination of sea water loop, drive desalination of sea water circuit cycle by heat-source Cycles pump 2 simultaneously, desalination of sea water flow process is completed through sea water desalinating unit 1, this device can reach diesel residual heat and utilize to greatest extent, be beneficial to environmental protection, and ensure diesel engine economy, reliable and safe operation.
As the preferred embodiment of the present invention, be connected with diesel engine cooling water tank 61 between the coolant outlet 64 of diesel cylinder sleeve 6 and cooling water intake 63, cooling water circulating pump 5 is installed between diesel engine cooling water tank 61 and cooling water intake 63.
The cooling water flowed out from the coolant outlet 64 diesel cylinder sleeve 6 can be passed through diesel engine cooling water tank 61, after supercooling, cool cycles is carried out entering diesel cylinder sleeve 6 in this circulation, also carry out heat exchange through heat exchanger 3 after can flowing into cooling water swelling water tank 15, then diesel residual heat is brought in desalination of sea water circulation loop.
As the preferred embodiment of the present invention, diesel cylinder sleeve 6 is provided with fan 62.
As the preferred embodiment of the present invention, coolant outlet 64 side is connected with the first input controller 7 and secondary signal detection control device 8 in turn.
As the preferred embodiment of the present invention, be provided with the temperature-controlled flow control valve 10 of parallel relationship each other, normally closed cut-off valve 9 and normally closed solenoid valve 11 between diesel engine cooling water tank 61 and coolant outlet 64, temperature-controlled flow control valve 10 is connected with the first input controller 7.
As the preferred embodiment of the present invention, what be connected with series relationship each other between cooling water swelling water tank 15 and coolant outlet 64 often drives stop valve 13 and normally open solenoid valve 14.
As the preferred embodiment of the present invention, be connected with alarm 12 between normally closed solenoid valve 11 and normally open solenoid valve 14, alarm 12 connects the first input controller 7 and secondary signal detection control device 8 simultaneously.
The temperature of the coolant outlet 64 of diesel cylinder sleeve 6 is between 65 ~ 85 DEG C time, and diesel coolant is in normal water temperature range.Now, diesel coolant bifurcation road enters heat exchanger 3 and the diesel engine cooling water tank 61 of low temperature seawater desalination system, cools respectively by as the fan 62 on the thermal source of low temperature seawater desalination system and diesel cylinder sleeve 6.Now, normally open solenoid valve 14 and Chang Kai stop valve 13 are in open mode, and normally closed cut-off valve 9 and normally closed solenoid valve 11 are in closed condition.The assignment of traffic of two branch roads is controlled by temperature-controlled flow control valve 10 and secondary signal detection control device 8.When the temperature that secondary signal detection control device 8 detects coolant outlet 64 place is 65 DEG C, temperature-controlled flow control valve 10 is in full-shut position, when the temperature that secondary signal detection control device 8 detects coolant outlet 64 place is 85 DEG C, temperature-controlled flow control valve 10 is in full-gear, and when secondary signal detection control device 8 detects the temperature at coolant outlet 64 place between 65 ~ 85 DEG C, the aperture of temperature-controlled flow control valve 10 correspondence 0 ~ 100%.Refill diesel cylinder sleeve 6 pairs of diesel engines by cooling water circulating pump 5 after diesel engine cooling water for cooling to cool, complete the circulation of cooling water.
When the first input controller 7 or secondary signal detection control device 8 detect that the temperature at coolant outlet 64 place is higher than 85 DEG C; but during tripping grinder temperature lower than diesel coolant; now alarm 12 is by high temperature alarm; and cause normally open solenoid valve 14 to close; normally closed solenoid valve 11 is opened; now, diesel coolant cools all flowing into diesel engine cooling water tank 61.When the first input controller 7 or secondary signal detection control device 8 detect that the temperature at coolant outlet 64 place returns normal temperature, then show that temperature-controlled flow control valve 10 or low temperature multi-effect seawater desalting system break down.Can close and often open stop valve 13, open normally closed cut-off valve 9, maintenance and inspection are carried out to temperature-controlled flow control valve 10 or low temperature multi-effect seawater desalting system fault.If the first input controller 7 or secondary signal detection control device 8 detect that the temperature at coolant outlet 64 place continues to raise, then show that the too high or equipment of diesel oil operating load exists fault, cooling water temperature is being controlled by diesel engine own control systems.
When the first input controller 7 or secondary signal detection control device 8 detect that the temperature at coolant outlet 64 place is lower than 65 DEG C, but during minimum temperature higher than diesel coolant, alarm 12 will produce low-temperature warning, and cause normally open solenoid valve 14 to close, normally closed solenoid valve 11 is opened, and diesel coolant cools all flowing into diesel engine cooling water tank 61.When the first input controller 7 or secondary signal detection control device 8 detect that the temperature at coolant outlet 64 place returns normal temperature, then show that temperature-controlled flow control valve 10 or low temperature multi-effect seawater desalting system break down.Can close and often open stop valve 13, open normally closed cut-off valve 9, maintenance and inspection are carried out to temperature-controlled flow control valve 10 or low temperature multi-effect seawater desalting system fault.If when the first input controller 7 or secondary signal detection control device 8 detect that the temperature at coolant outlet 64 place continues to reduce, then show that the too low or equipment of diesel oil operating load exists fault, cooling water temperature is being controlled by diesel engine own control systems.
Because the control temperature scope 65 ~ 85 DEG C of this control system is within the suitable operating temperature range 60 ~ 90 DEG C of diesel coolant, the control system of diesel engine self can be made full use of, ensure the handling safety of diesel engine self.
In addition, because the most high evaporation temperature of low temperature multiple-effect distillation is no more than 75 DEG C, therefore the design temperature of the thermal source of low temperature multiple-effect distillation seawater desalination system is generally no more than 80 DEG C, to avoid the fouling of inorganic salts in vaporizer.
Thus the present invention is by the distribution of temperature-controlled flow control valve 10, and diesel coolant water temperature is higher, distributes the cooling water flow entering into low temperature multiple-effect distillation seawater desalination system and reduces, the heat source temperature of seawater desalination system can be avoided too high.And when diesel coolant water temperature is on the low side, distributing the cooling water flow entering into low temperature multi-effect seawater desalting system raises, utilize cooling water heat substantially.
Certainly, the invention is not limited to above-mentioned mode of execution, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent modification or replacement are all included in the application's claim limited range.
