exemplifying embodiment
By reference to the accompanying drawings, the invention process example is as follows:
1, angle of solar battery system
Angle of solar battery system take micro-chip as process core, can adopt STC89C52, and DC/DC change-over circuit realizes maximum power point (MPPT) and follows the tracks of, and system adopts conventional BUCK circuit to realize maximal power tracing.In order to improve system reliability, introduce reverse connection prevention protection circuit and current foldback circuit.Because angle of solar battery system application is ripe, the present invention repeats no more herein.See Fig. 1.
2, water cleaning systems
Core water treating equipment of the present invention are RO film, and the preposition pre-processing device of RO film is configured with: preposition sand-bed filter, preposition PP cotton, preposition activated charcoal filter post.Preposition sand-bed filter filtrate employing retaining power is strong, filtering velocity is high, packing ratio heavy and light, the ceramic grain filter that intensity is large, stable chemical performance, anti acid alkali performance can be strong, and object is that reply possibility Yuan Shui water source turbidity is higher.The first step sand coarse aggregate ratio that former water carries out treating nature water by low-tension switch is filtered, and low-tension switch is the power supply of pressure lower than cut-out water pump during rated pressure, works when preventing water cleaning systems anhydrous, securing system.
Second step and the 3rd step are filtered by preposition PP cotton, preposition activated charcoal filter post, then by under the reverse osmosis pressure of booster water pump, by RO film, pure water is separated with pressurized water, then again filtered by post active carbon filter post, be, again by rearmounted overflow-type ultraviolet sterilizer, the water purification prepared finally by high-voltage switch gear and under meter enters water storage barrel.High-voltage switch gear is the pump power cutting off water cleaning systems when water storage barrel is expired, quits work.Under meter provides accumulative preparation through the water yield one numeral directly perceived to user, and in good time, more renew cartridge, filtrate provide a reference.
System integration scouring electromagnetic valve, adopt water purifier component market, market to commonly use carry waste water ratio certainly rush time delay 18 seconds magnetic valves, system all starts scouring electromagnetic valve in each start and when shutting down and carries out back flushing work.
Reverse checkvalve effect be the pure water of RO film output enter pressure-pot water storage barrel, Zhi Nengjin, can not reflux.
The water outlet of purifier installs overflow-type ultraviolet sterilizer, and ultra-violet sterilization wave band is mainly between 50 ~ 300nm, wherein the strongest with the sterilizing ability of 253.7nm wavelength.When the various bacteriophagees in water or air are through ultraviolet (253.7nm wavelength) irradiation area, ultraviolet penetrates microbial cell film and nucleus, destroy the molecular linkage of nucleic acid (DNA or RNA), make it lose replication or to lose activity and dead, thus killing bacteriophagees all in water or air when not using any chemicals.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
