The working process of this example:
When the valve opening of more medium filter, activated charcoal filter is to standard state, start raw water pump, open the vent valve of cartridge filter, carry out exhaust, until there are flowing out, operation enters next procedure.
Under reverse osmosis subsystem equipment normal running (operation) conditions, the Stainless Steel Ball Valve of the total inflow of reverse osmosis part after by high-pressure pump controlled, in the time of operation, prevent high-pressure pump lack of water idle running, need to check pump intake valve, and back out after Exhaust screw drains gas and put into operation again.Reverse osmosis can start flushing when automatically moving, flush time is half a minute, object is to rinse out pollutent or the stores that is attached to film surface, now, " RO flushing " pilot lamp on electronic box panel is illuminating state, should be after high-pressure pump starts at least 5 minutes while recording pressure, flow and specific conductivity as need record again because at this time parameters tends towards stability.
During mixed bed subsystem work, be divided into following steps (1) backwash layering: first close outlet valve, then drive lower water intaking valve, upper water discharge valve, current enter from bottom, and discharge at top, now can regulate pure water pump reverse flow valve increased water flow, resin is all held up and stirs loosely, then close pure water pump.If now, resin occurs uniting and stirs not loose situation, slowly opens air inlet valve, is aided with pressurized air and is stirred loose.After layering success, open lower water discharge valve, the water level in mixed bed is drained into the position higher than the general 15 centimetres of left and right of resin layer, close pump water valve.(2) regeneration negative resin: the flexible pipe that suction alkali lye is used inserts in ready alkali lye, drives alkali lye inlet valve, half-open alkali lye outlet valve, crack lower water intaking valve.Starting pure water pump, regulates alkali lye outlet valve, makes flux of alkaline liquor at 200L/H, and regulates lower water intaking valve simultaneously, and the liquid level on mixed bed top is remained unchanged.(3) rinse negative resin: approximately, after one hour, alkali lye sucks.Half-open upper water intaking valve, closes alkali lye inlet valve, alkali lye outlet valve, keeps other valves constant, notes regulating upper water intaking valve, lower water intaking valve to keep the liquid level of mixed bed simultaneously.Until negative resin rinses to neutrality, stop pump and close above-mentioned all valves.(4) the positive resin of regenerating: be inserted in ready acid solution inhaling the flexible pipe that acid solution uses, drive acid solution inlet valve, half-open acid solution outlet valve, crack upper water intaking valve.Start pure water pump, regulate acid solution outlet valve, make acid solution flow at 100L/H, and regulate upper water intaking valve simultaneously, mixed bed liquid level is remained unchanged.Etc. (5) acid solution sucks, and half-open lower water intaking valve, closes acid solution inlet valve, acid solution outlet valve, keeps other valve states constant, notes regulating upper water intaking valve, lower water discharge valve to keep the liquid level in mixed bed simultaneously.(6) just washing resin: drive water intaking valve, lower water discharge valve, open pure water pump and rinse resin approximately 5 minutes, water will be filled with in mixed bed, close pump water valve.(7) gas is mixed: drive water discharge valve, slowly open air inlet valve, the then rapid draining of water discharge valve under standard-sized sheet, during lower than resin layer, closes air inlet valve until water level.(8) rinse resin: drive water intaking valve, lower water discharge valve, until be flushed to neutrality.(9) normal operating condition, opens water intaking valve, outlet valve, and all the other Close Alls start pure water pump.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
