Abstract
The present invention relates to a method for protecting an enamel internal container of a water-heater and a device thereof, which is composed of a main body of the water heater, a titanium metal bar, namely a titanium anode bar which can be positioned in water and can be applied by 2 to 10V of positive voltages, and a correspondent low-voltage DC power supply, wherein the DC power supply is composed of rectification, wave filtering and voltage stabilizing circuits, status display circuits and backup batteries which can be charged in use. The titanium bars can be kept into a positive potential under the condition that the water heater is stopped for heating for several days. The enamel inner container of the water heater is protected by that the titanium anode bars which are applied by the positive voltage are used for eliminating electrolytic harmful effects to greatly improve the service life of the water heater.
Description
The present invention relates to a kind of method for protecting enamel internal container of water-heater and device.
The meta-acid of running water or meta-alkalescence can be the weak electrolyte characteristic after heating, therefore will produce corrosion function to the water heater inwall, and when on its enamel adamantine layer sand holes being arranged, this corrosion function aggravation will influence the service life of water heater liner greatly.Discover; even finish using; because hot water still can not cool down in the courage, weak electrolyte still exists, and owing to enamel inner container is heated; protective layer still can weather greatly because of micropore becomes; and existing technology only is provided with a metal magnesium rod of magnesium in inner bag water, and to block the etching effect of this weak electrolyte, service time is short; even promptly need change in 1 year, and anticorrosion descale effect is not good.
The objective of the invention is to overcome above-mentioned shortcoming, a kind of method for protecting enamel internal container of water-heater and device are provided.
The present invention is that the titanium system metal bar that chemical stability is good replaces the magnesium rod to be fixed in the water; and supply with positive voltage below the stable 10V by a low-voltage dc power supply; make water heater be the anodic protection state; and the power supply ground that isolates fully with civil power ground wire end is connected water heater liner; even deenergization, the reserve battery that wherein is recharged still can work on a couple of days.
Provide specific embodiments of the invention below in conjunction with accompanying drawing.
Fig. 1 basic structure schematic diagram of the present invention.
Fig. 2 circuit theory diagrams of the present invention.
As shown in the figure, the present invention is by low-voltage dc power supply 1, water heater main body 4 is formed with a metal bar 7 that places the aqueous medium 6 in it, and the metal bar 7 that is fixed on housing bottom is connected with the positive pole 3 of dc source 1, and being applied in the DC voltage of one 2～10V, the negative pole 2 of its dc source 1 is connected and ground connection with water heater liner 5 via bolt 8.Above-mentioned dc source 1 as Fig. 2, is common regulator rectifier circuit, low-tension transformer T is through bridge rectifier B, filter capacitor C and mu balanced circuit 10, via three diode D1～D3,, and between A, K, connect a common status display circuit 9 again by P and the output of K point.Consider the anodic protection state that must keep metal bar 7 after the outage, hold reserve battery E in parallel, be recharged during work, still can make the titanium rod be in positive potential in a couple of days, corrode with effective blocking-up in order to stopping to heat the back at output terminals A K.Usually the output voltage of dc source is that 3.5V is advisable.The titanium rod that 7 of above-mentioned metal bars select for use Titanium or its alloy to make.The reserve battery E that above-mentioned dc source 1 comprises can be high-quality small battery or the rechargeable battery in parallel with output terminals A, the K of dc source 1, even stopping to heat, water heater still can make metal bar be in positive potential in a couple of days, thereby the light current that can remove hot water is effectively separated ill-effect, improves the service life of water heater greatly.
The guard method of above-mentioned enamel internal container of water-heater is the water 6 that the metal bar 7 of titanium or titanium alloys is placed water heater liner 5, and is provided with positive potential between 2～10V with low-voltage dc power supply 1, separates ill-effect to eliminate light current, obtains the anodic protection state.Obviously, the present invention is simple in structure, and is reasonable in design, can improve the service life of water heater greatly.
