Description
Technical field
The utility model relates to a kind of intelligence control system, is the intelligence control system of reverse osmose pure-water equipment specifically, belongs to automation control area.
Background technology
Understand according to the applicant; development along with the water treatment facilities application technology; in pure water system, generally all can adopt counter-infiltration (RO) pure water equipment; and in the application of counter-infiltration (RO) equipment; usually can adopt polyamide rolling composite membrane; the quality of reverse osmosis membrane will directly have influence on the stability of whole system, therefore because importance and the singularity of reverse osmosis membrane.
Present pure water system generally all is to use the control model of system convention, and this control model generally has no water conservation, the protection of high/low pressure, liquid level control and start/shutdown washing capacity, will analyze one by one the problem that this pattern exists below:
1. system boot/shutdown: this action is to open and stop according to front and back high water tank high-low signal, because the equipment operating pressure is higher, coiled reverse osmosis membrane can be because the former thereby deformed damaged of water hammer.Therefore generally can adopt water inlet to hold valve or the operation of variable frequency control high-pressure pump and start and stop slowly, the former mechanical forced sexual act failure rate height, shutdown is to play buffer action, latter's performance is pretty good but expense is higher.
2. system's operation: equipment can occur anhydrous or water inlet low pressure in the operational process, situations such as water outlet high pressure, and way is to shut down after receiving fault-signal and warning usually, can need like this to wait for and manually carry out reset processing, otherwise will influence the operation of whole system.
3. system is cleaned: the Design Mode of equipment routine is when start and shutdown reverse osmosis membrane to be washed; if but because water is former thereby make equipment long-time when out of service or long during operation; reverse osmosis membrane will can not get effective cleaning, cause the long bacterium in film surface and dirty the blocking up of reverse osmosis membrane seriously can't thoroughly clean up.
The utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, a kind of automatic steady switching on and shutting down is provided, moves and judge whether to have fault and the intelligence control system of the reverse osmose pure-water equipment that cleans automatically automatically.
In order to solve above technical matters, the utility model provides a kind of intelligence control system of reverse osmose pure-water equipment, comprise water inlet, high-pressure pump, reverse osmosis membrane, water delivering orifice and PLC controller, water inlet is by the fixedly connected high-pressure pump of first water pipe, high-pressure pump connects reverse osmosis membrane by second water pipe, and reverse osmosis membrane is by the fixedly connected water delivering orifice of the 3rd water pipe, and first water pipe is provided with low tension switch, high-pressure pump is provided with soft initiator, and second water pipe is provided with high-voltage switch gear; Also be provided with the 4th water pipe on the reverse osmosis membrane, the 4th water pipe is connected to the flush discharge mouth; The PLC controller is controlled described low tension switch, soft initiator and high-voltage switch gear by control circuit;
The control employing soft start controller of high-pressure pump need not to use and drives valve and frequency converter slowly, can slowly start or stop high-pressure pump the start-up time when only needing to set start or shutdown, has avoided the impact of high pressure water hammer to reverse osmosis membrane; Under the monitoring of system pressure switch, when system occurs that water inlet is anhydrous, when low pressure and water outlet high pressure conditions, by programmable controller equipment is carried out self check, be as the criterion in one minute, to carry out three minor loop self checks, fault eliminates then that system starts operation automatically, on the contrary equipment downtime and report to the police and wait for artificial treatment; In the start of equipment routine, carry out outside the flushing of reverse osmosis membrane when shutting down; by the control of PLC controller logic equipment is accumulated timing; long-play 3 hours or when shutting down 3 hours; automatically the flushing reverse osmosis membrane once blocks up and shuts down for a long time the long bacterium on film surface to prevent long playing dirt.
The technical scheme that the utility model further limits is:
Preferably, the 3rd water pipe is provided with and produces the water water quality analyser and produce water ga(u)ge.
Preferably, be respectively arranged with the control circuit that is connected the PLC controller on product water water quality analyser and the product water ga(u)ge.
Preferably, the 4th water pipe is provided with the flush discharge valve.
Preferably, the flush discharge valve is provided with the control circuit that connects the PLC controller.
The beneficial effects of the utility model are: the utility model fully-automatic intelligent control model is the stable operation of support equipment effectively; probability of malfunction, input cost have been reduced; improved work efficiency, effectively protected reverse osmosis membrane, the medicine that has prolonged film is washed cycle and serviceable life.
