Description of drawings
For let above-mentioned purpose of the present invention, feature and advantage can be more obviously understandable, elaborate below in conjunction with the accompanying drawing specific embodiments of the invention, wherein:
Fig. 1 illustrates the synoptic diagram of a recirculating cooling water system.
Fig. 2 illustrates the opening/closing control device schematic diagram of one embodiment of the invention.
Fig. 3 illustrates the opening/closing control device schematic diagram of another embodiment of the present invention.
Embodiment
Comparatively complicated situation is operated in switching on and shutting down to Water Treatment in Circulating Cooling System, and embodiment proposed by the invention can realize the automation mechanized operation to these disposal system startup and shutdown, need not special operating personnel and carries out.Can link with the cooling-water pump of handpiece Water Chilling Units simultaneously, automatically system is carried out the operation of startup and shutdown according to the start and stop situation of cooling-water pump.
Fig. 1 illustrates the synoptic diagram of a recirculating cooling water system.In this system, have water chilling unit system 100 and Water Treatment in Circulating Cooling System 200.Water chilling unit system 100 typically comprises cooling tower 102, cooling-water pump 104 and handpiece Water Chilling Units 106, and the three constitutes a water cycle.Water Treatment in Circulating Cooling System 200 can have different formations according to different processing modes.In the example shown in Fig. 1, used ozone treatment.Water Treatment in Circulating Cooling System 200 comprises air compressor machine 202, cooling driers 204, supercharge pump 206, oxygenerator 208, ozone machine 210, ozone resolver 212 and solenoid valve 214.The quantity of supercharge pump 206 can be one or more.Solenoid valve 214 can comprise electrical ball valve, drain solenoid valve etc.The parts that are appreciated that Water Treatment in Circulating Cooling System 200 can perhaps increase in partly replacement, minimizing.
In Water Treatment in Circulating Cooling System 200, also comprise contain Programmable Logic Controller (Programmable Logic Controller, PLC) 216, be used for splitting, shutdown programm controls.Programmable Logic Controller 216 can be electrically connected to above-mentioned air compressor machine 202, cooling driers 204, supercharge pump 206, oxygenerator 208, ozone machine 210, ozone resolver 212 and solenoid valve 214, according to open and close machine program these parts are controlled.
Fig. 2 illustrates the opening/closing control device schematic diagram of one embodiment of the invention.In this embodiment, the start stop signal of cooling-water pump 104 in the water chilling unit system 100 is linked to each other with the input end of the Programmable Logic Controller 216 of Water Treatment in Circulating Cooling System 200, constitute an opening/closing control device.The contactor 105 of control cooling-water pump 104 operations is as the start and stop indicating device of cooling-water pump 104.
The start and stop of cooling-water pump 104 can reflect directly whether whole water chilling unit system 100 moves.When cooling-water pump 104 started, contactor (KM) 105 auxiliary contact of control cooling-water pump 104 operations were closed, after Programmable Logic Controller 216 is received closure signal, start shooting by the start step of writing in advance.After start was accomplished, system was in running status.
When cooling-water pump was shut down, contactor 105 auxiliary contact of control cooling-water pump 104 operations broke off, and after Programmable Logic Controller 216 is received cut-off signal, shut down by the shutdown procedures of writing in advance.Whole process all can be accomplished automatically, need not manual intervention.
For system shown in Figure 1, the automatic switching step is:
Start flow process: drive cooling driers 204, air compressor machine 202, ozone resolver 212; A opens into water, water outlet motorized valve after second; B opens supercharge pump 1 after second; C opens supercharge pump 2 after second; D opens oxygenerator 208 after second; After e minute, open ozone machine 210; After f minute, promote the electric current of ozone machine 210.
Shutdown process: the electric current that reduces ozone machine 210; Close ozone machine 210 after g minute; H closes oxygenerator 208 after second; I closes air compressor machine after second; J closes supercharge pump 2 after second; K closes supercharge pump 1 after second; L closes into water, water outlet motorized valve after second; M closes cooling driers 204, ozone resolver 212 after second.
Wherein but parameter a～m is a setup parameter.
In other embodiments, the contactor auxiliary contact that are used for reflecting the cooling-water pump operation also can be got other signal and replace.If contactor does not have vacant auxiliary contact or the dried up process control system of contactor far away, another embodiment that can be as shown in Figure 3, from the cooling-water pump run indicator 104a number of winning the confidence on the spot, whether reflection cooling-water pump 104 moves.Needing this moment increases an auxiliary reclay (KA) 104b as cooling-water pump start and stop indicating device, and active signal is become passive contact.Auxiliary reclay 104b remains and is connected to Programmable Logic Controller 216, and the start stop signal of cooling-water pump 104 is sent into Programmable Logic Controller 216, and the latter will carry out the motor-driven work of open and close according to aforesaid open and close machine flow process, repeat no more at this.
Therefore, embodiment described in the invention can realize the automation mechanized operation to the Water Treatment in Circulating Cooling System startup and shutdown, need not special operating personnel and carries out.Can link with the cooling-water pump of handpiece Water Chilling Units simultaneously, automatically system is carried out the operation of startup and shutdown according to the start and stop situation of cooling-water pump.
The present invention can be used for the ozone method of rail traffic station central air conditioner recirculated cooling water and handles.
Though the present invention discloses as above with preferred embodiment; Right its is not that any those skilled in the art are not breaking away from the spirit and scope of the present invention in order to qualification the present invention; When can doing a little modification and perfect, so protection scope of the present invention is when being as the criterion with what claims defined.
