The specific embodiment
Accompanying drawing 1 has shown the ozone clothes washing system 100 that adopts various principles of the present invention and notion.System 100 has comprised ozone generation subsystem, ozonated water generation subsystem, ozonated water transmission and Monitor And Control Subsystem and RACS.Below, in these subsystems each is described in detail.
Ozone generation subsystem produces system's 100 necessary ozone.The following realization of the generation of ozone.Extraneous air is fed into compressor 108 via inlet 106.During preparation ozone, dry air and the higher air of oxygen concentration can produce more ozone.Therefore, it is favourable controlling the moisture of introducing air by the temperature of control air.Make outside air can finish this point by compressor 108.Compressor 108 also can be conventional conditioner.Then, the cold dry air with gained offers oxygen concentrator 110, concentration of oxygen (for example may be increased to 80-90% from 20%) in these oxygen concentrator 110 increase air.Compressor 108 and oxygen concentrator 110 are examples of " regulating (conditioning) " device, and said " adjusting " device can be regulated air to obtain required air characteristics.Also can use other " adjusting " device.
Then, the air of adjusted mistake is delivered in the oxygen generator 112, nitrogen is separated from oxygen.Subsequently, the dry air of this elevated oxygen level is delivered to ozone generator 114 by pipeline 113.In a specific embodiments, ozone generator 114 produces an electrion, and an oxygen molecule is split into two oxygen atoms, and these two oxygen atoms and other two molecules bump against then, wherein have one to be oxygen molecule (O
2).Be connected voltage regulator (VR) 115 on the ozone generator 114 by adjusting, can control or change the quantity of the ozone of generation.
The ozone that comes out from ozone generator is sent to a water-filled contacting container 118 by Venturi tube (venturi) 116, and a valve 150 is arranged between contacting container 118 and the watering.In contacting container 118, ozone mixes with water, generates ozonated water.In the specific embodiments shown in the accompanying drawing 1, ozonated water generation subsystem comprises single contacting container 118.In other specific embodiments, also can use a plurality of contacting containers to produce and store ozonated water.In case when system opens, suppose that contacting container 118 is full, the quantity that injects the ozone of this container so can be by RACS by following described control.Required ozonated water is supplied to wash mill 166a to 166d via water supply pipe 152 and valve 154.Supply pump by RACS by following described control.
Among the wash mill 166a to 166d each can be that commercial laundromat, self-service laundry, hotel, school, dormitory or other will clean the washing machine of common type used in the mechanism of a large amount of clothings.Among the wash mill 166a to 166d each can independent operation, and can comprise washer-extractor machine (washer extractor) and/or continuous batch washer (tunnel washer).Among the wash mill 166a to 166d each can be used ozonated water or non-ozonated water (for example daily water consumption) neatly.Among the wash mill 166a to 166d each can perhaps be supplied by penstock 168a to 168d by contacting container 118 via water supply pipe 152 supply ozonated waters.If do not need ozonated water, valve 154 is closed so, and penstock 168a to 168d is opened with 203a to 203d simultaneously, and penstock 204a to 204d is closed simultaneously.Among the wash mill 166a to 166d each can be supplied ozonated water via water supply pipe 152 from contacting container 118, and can mix with cleaning solution (wash liquor), introduces the required cleaning fluid (cleaning fluid) of washing process.
RACS guarantees that the ozonated water that will have required redox ability (ORP) or ozone concentration offers wash mill 166a to 166d.RACS is at the height of each position monitoring of whole system ORP, and its implementation is: the select location in system is equiped with the sensor 151 and the 165a to 165d of dissolved ozone, and monitors these sensors.Be lower than selected ORP value if certain in these sensors demonstrates its ORP value, RACS will stop to transmit ozonated water in wash mill so, up to reaching selected ORP value.The valve of circulating device 121 and syringe pump 120 also are activated.So ozone is pumped into contacting container 118 via Venturi tube 116, and form small bubble in the bottom of contacting container 118.Form the ozone of dissolving behind these bubble contact water.Said sensor continues monitoring ORP value, and the ORP value signal notice RACS that is monitored.Water continues circulation up to reaching through selected ORP value.
RACS is equiped with programmable logic controller (PLC), processor, controller, microcontroller, microprocessor, control relay or other can carry out the electronic installation of function described herein.This RACS can be designed to allow the Long-distance Control visit, and these needs on wash mill are decided.This RACS typically includes computer software, control relay, timing means, automatic valve operation and hand control valve operation.Depend on that system 100 wants the automaticity that reaches, PLC can control ozone and be injected into amount in the washings, to realize different results.
The present invention allows operating personnel freely to determine ozone to be mixed to the mode in the washings, makes to reach selected ORP value in wash mill 166a to 166d washed water.More particularly, operating personnel can: (1) uses the ozonated water from contacting container 118 as mentioned above, perhaps (2) are simply by cutting off being communicated with of contacting container and water supplying pipe 152, do not use any ozonated water, perhaps (3) utilize wash mill 166a to 166d as contacting container, adopt the Venturi tube 200a to 200d of assembling, automatic valve 201a to 201d, static mixer 202a to 202d, valve 203a to 203d and 204a to 204d, and check valve 205a to 205d, ozone directly is injected into water supplying pipe road 168a to 168d from ozone generator, then ozonated water is sent to wash mill 166a to 166d.When ozone directly was injected into the water supplying pipe road, system just no longer needed sensor and loops back receiving apparatus (recirculationmechanism).The size of ORP value depends on the intake rate of current and the Grams Per Hour value of (weight percentage) ozone under specific ozone concentration.
The size of selected ORP value depends on various factors.These factors comprise the distance between character, contacting container and the wash mill at characteristic, ventilating system, water source of laundry item, conceivable effect or the like.
Last at washing process, water is discharged to sewer from wash mill 166a to 166d via drainpipe 164a to 164d respectively.Sometimes, in the time will reusing water, the water of discharge can supply to a puddle groove (sump bath) 211., before entering the puddle groove, filter from the sewage of wash mill 166a to 166d, to remove bigger particulate (75 microns or bigger) and Soft flocks in the sewage through coarse grain filter or screen cloth bag filter 210.When this puddle groove was filled with, a level switch activator draining pump (sump pump) 212 was sent into water in the container 213 that is fixed with granular membrane.The second level switch activator transfer pump 214 of this mesh container transmits water by an automatic back scrubbing multimedia filter 215, removes particulate in the water more than 20 microns.
Then, the current contacting container 216 that advances to circulate.Similar injection ozone is injected into ozone the circulation contacting container and produces small bubble by syringe pump 217 via Venturi tube 218 to the initial procedure of contacting container 118.Bubble enters into the bottom of this container.When bubble rises to water surface, bubble is carried into this vessel surface with remaining more small particle, oil and grease molecule.This process is called air and induces floating (induced air flotation).When circulation contacting container fills with water, the particulate and the oil film that overlay on the water surface are directed to an overfall and are discharged to sewer.Being dissolved in the storage container ozone in the running water can oxidation foul smell molecule, virus, bacterium and other organic pollutions.When needed, water transfer pump 219 is sent to first contacting container 118 with water from the circulation contacting container, and at this moment whole process has begun again.
This ozone clothes washing system and method provide many-sided benefit.Change mode of washing, comprise wash cycle cycle, cleaning solution when changing selected ORP value, use ozonated water quantity, cleaning solution kind and/or go into coolant-temperature gage, can reach conceivable effect of ozone treatment and efficient.The efficient of laundry treatment can be weighed by the use of the use that reduces water, the use that reduces chemicals, minimizing energy, the use that reduces the labourer or the like.
Fig. 2 has shown the whole control process of ozone washing system, and it comprises two complementary control system-RACSs 500 and wash mill control programmable device 600.Wash mill control programmable device 600 (being called " programmable device " later on) is used to produce the mode of ozone washing.By this programmable device, can control under each ozone washing mode, time of each wash cycle and go into coolant-temperature gage.Depend on the type of institute's employing wash mill in the system, the kind of cleaning solution and consumption both can be controlled automatically by programmable device, also can manually be controlled by the operator.
If select the ozone washing mode by programmable device during washing, RACS 500 will be activated so.ORP recipient 502 transmits control signal to PLC503 continuously, and this control signal depends on the ORP value that ORP/ ozone sensor 501 is detected herein.According to this control signal, the startup of PLC502 control air compressor and oxygen generator 504, ozone generator 505, transfer pump 506 and syringe pump 507.
