Abstract
The invention discloses a method for controlling the quality of de-ionized water of an electrolytic ozonizer. A de-ionized water tank is used for containing the de-ionized water, the electrolytic ozonizer is connected with the water tank, and a liquid level meter used for monitoring the liquid level is arranged in the electrolytic ozonizer. When the liquid level meter generates a water shortage signal, the de-ionized water is added into the de-ionized water tank; when the liquid level meter generates a full water signal, the de-ionized water is stopped being added into the de-ionized water tank. The invention is characterized in that the method further comprises the following steps: when the ion content of the de-ionized water in the de-ionized water tank increases, the de-ionized water is forcibly added into the de-ionized water tank for at least 5 minutes immediately and the original de-ionized water in the de-ionized water tank is drained so as to reduce the ion content of the de-ionized water. The method is cycled continuously and ensures that the de-ionized water, as raw material, can maintain excellent low electrical conductivity after a long-time operation of the electrolytic ozonizer, thus leading the electrolytic ozonizer to generate stable ozone output and achieving stable performance.
Description
Technical field:
The present invention relates to a kind of is the control method of quality of de-ionized water in the electrolysis ozone generator of raw material with the deionized water, belongs to the electrolysis ozone generator technical field.
Background technology:
At present, with the deionized water control method that the electrolysis ozone generator of raw material has multiple quality of de-ionized water, for example: Chinese patent application 97122126.X is arranged, and denomination of invention is the patent of invention of " electrolytic ozone generator ".Its control method to deionized water is: when liquidometer produces the lack of water signal, begin to add deionized water to the deionization water tank; When liquidometer produces the full water signal, stop to add deionized water to the deionization water tank.
Above-mentioned control method has following shortcoming:
1, electrolysis ozone generator is raw material with the deionized water, in operational process, be hydrogen and oxygen constantly with the deionized water electrolysis, deionized water is constantly consumed, the liquidometer monitoring liquid level that relies on the deionization bucket to be set up, only keep supplying the water yield of electrolysis generator demand, can't effectively control the water quality of deionized water.
2, the needed raw material of electrolysis ozone generator is a deionized water, but all ions in the water can't be removed fully with present scientific approach and technology, because electrolysis ozone generator is deionized water completely because of electrolysis consumed, other ions of these trace do not participate in electrolytic reaction consumption, make it along with the electrolysis generator running will exist always; Along with deionized water constantly consumes, will constantly add deionized water, also add other ions of trace simultaneously, so circulation causes the continuous cumulative rises of other ions of these trace, and then pollutes the water quality of deionized water, make the electrolysis ozone generator degradation, the ozone generation amount reduces.
3, ozone has extremely strong oxidation corrosion, and in operational process, most of material that contacts with ozone all can oxidizedly corrode, and generates oxide compound and impurity; Even after long-time the use, the material of contact other ions that also can dissociate, no matter produce in which kind of mode, when these materials with will pollute quality of de-ionized water after deionized water contacts.
4, when the extremely low liquid level of liquidometer monitoring, produce the lack of water signal, adding deionized water only dilutes the concentration of other ions, impurity and oxide compound in original deionized water, there is no and discharge original deionized water, wherein other ions, impurity and oxide compound are constantly increased, cause water quality constantly to worsen, influence the electrolysis ozone generator performance, and then the reduction of ozone generation amount, see the following form 1.
