Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
Embodiment 1
Boats and ships desulfurization wastewater treatment system, comprises PLC control system, filtering system, treats filtrate receiver, holds the waste water after desulfurization until filtrate receiver, and filtering system is used for the filtration of desulfurization wastewater, and PLC control system controls the treating processes of desulfurization wastewater.
Filtering system is made up of the identical device of two covers, often overlap filtering system and include filtrate machine, with the liquidometer and the discharge pipe that are arranged on filter top, discharge pipe is provided with delivery gauge and electronic outlet valve, the desulfurization wastewater that discharge pipe is up to standard after being used for emission treatment.
Be provided with filter core in filter, bottom is discharge outlet, and discharge outlet place is provided with automatic discharging valve 3; Discharge outlet place is also provided with vibrations big gun 31, is provided with dry cake collector 32 below discharge outlet.
Treat that filtrate receiver is connected with the filtrate inlet of filter through filtrate line system, filtrate line system comprises filtrate line and filtrate branch road, electronic inlet valve 12 controls to treat being communicated with of filtrate receiver and filter I1, and electronic inlet valve 21 is for controlling to treat opening and closing of filtrate receiver and filter II2.Filtrate line arranges inlet pressure gauge 11, measures the intake pressure of filtrate machine.Electronic spill valve 13 is set between filtrate branch road and filter I1, and is also provided with electronic spill valve between filter II2.
Waste Water Treatment also comprises cleaning system, for cleaning filter filter core.Cleaning system, by pressurized air and cleaning water cleaning filter filter core, comprise source of the gas, main gas circuit and be connected with main gas circuit three gas circuits; Be respectively a gas circuit I, a gas circuit II, a gas circuit III, a gas circuit I leads to filter core outside, and a gas circuit II leads to filter core inside, and a gas circuit III leads in filter core; Main gas circuit is provided with pneumatic main valve 4, an a gas circuit I and gas circuit II is respectively arranged with pneumavalve 42 and 43, a gas circuit III is provided with Pneumatic impulse valve 44.Cleaning system also comprise the cleaning water pipeline be arranged on above filtrate machine, and cleaning water pipeline is provided with Pneumatic water valve, pass into cleaning water by cleaning water pipeline.
When carrying out desulfurization wastewater process, first PLC control system controls all connection valves that filtrate receiver and filter II2 are treated in segment.Close the electronic spill valve 13 that filtrate branch road communicates with filter I1, open filtrate line communicates with filter I1 electronic inlet valve 12, open electronic outlet valve 5, waste water to be filtered enters in filter I1 through filtrate line, the waste water handled well is discharged through electronic outlet valve, the liquid level in filter I1 measured by liquidometer 52, avoids liquid level too high, and namely waste water do not discharge through complete filtration.
In wastewater treatment process, the force value that inlet pressure gauge 11 and delivery gauge 51 are measured feeds back to PLC control system.The force value of inlet pressure gauge 11 is steady state value, and the force value of delivery gauge 51 is changing value, the throw out piled up in filter core with filter I1 gets more and more, top hole pressure will increase gradually, if the pressure reduction between delivery gauge and inlet pressure gauge is excessive, PLC control system then judges that the filter core of filter I1 inside reaches capacity, and needs to carry out filter core process.
Now, first close electronic outlet valve 5, be communicated with the electronic inlet valve 12 of filter I1, open the electronic inlet valve 21 being communicated with filter II2, filter II2 repeats the desulfurization wastewater process operation before filter I1.Supersaturation process is carried out to filter I1 simultaneously, connect source of the gas, open electronic spill valve 13, open pneumatic main valve 4, open the pneumavalve 42,43 on an a gas circuit I and gas circuit II, ventilate in filter core He outside filter core, in venting process, liquid remaining in filter I1 is discharged through electronic spill valve 13, in filter core and the filter core filtrate of adhering to outward dry up; After for some time, open the Pneumatic impulse valve 44 on a gas circuit III, close the pneumavalve 42,43 on an a gas circuit I1 and gas circuit II, open automatic discharging valve 3, continue to dry up and blow down process to the adsorption precipitation thing in filter core.Throw out after drying up will fall into the discharge outlet place of filter I1, and discharge outlet vibrations big gun 31 shakes and drives filter I1 vibrations to discharge, and throw out falls into the form of dry cake in dry cake collector 32.
After thing row to be precipitated is quiet, close automatic discharging valve 3, open electronic spill valve, open the pneumavalve 42,43 on an a gas circuit I and gas circuit II, close the Pneumatic impulse valve 44 on a gas circuit III, close the electronic outlet valve of discharge pipe, open the Pneumatic water valve on cleaning water pipeline simultaneously, in filter, pass into clean water, cleaning filter core, containing throw out in water after cleaning, will flow back to from electronic spill valve 13 and treat filtrate receiver, this part recirculation water can discharge after secondary filtration.
After filter I1 cleaning terminates, enter dormant state, after machine II2 to be filtered is saturated, PLC control system will control to treat the connection of filtrate receiver segment and filter II2, connect the connection of itself and filter I1, clean filter II2.
Embodiment 2
Design cleaning water pipeline is the cleaning effect in order to strengthen filter core, and once, in actual application, the design for simplied system structure also can omit the setting of cleaning water pipeline in separated in time cleaning.When filter is saturated, only clean filter core by pressurized air, dry throw out.
