ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a detecting and analyzing apparatus for positive ions and negative ions present in a liquid, and more particularly, to a detecting and analyzing apparatus for positive ions and negative ions in a liquid, that is capable of measuring positive ions, negative ions, and charge density which are present only in a small amount in the liquid.
2. Description of the Related Art
Contamination of air and water is becoming significant as the living environment changes. However, no evaluation method for determining such contamination is available.
In the case of running water, although quality and testing criteria are issued, even if one drinking water sample satisfies such testing criteria, this sample can be insufficient in terms of a taste evaluation. In particular, even if certain running water supplies satisfy the issued criteria as a drinking water, some supplies may be good in taste, and other supplies may be bad in taste. Such a difference is caused by a difference of raw water source, a difference in purification process (e.g., difference in the sequence of the process steps, difference in application timing of a process agent, and the like), a difference in degree or kind of contamination of the raw water source, a difference in minerals present in the raw water source, and the like.
Further, in recent years, drinking water is processed by various means to meet quality criteria, but water evaluation is insufficient. This is because the water is analyzed based on its pH, electrical conductivity, chemical components, and the like.
As described above, water contains a variety of materials, and water processing methods differ. Therefore, recently, it has become necessary, in some cases, to use a water-purification device, or an alkali ion water-purification device, rather than drinking the running water as supplied, or it is necessary to further purify waterworks water. For these reasons, waterworks water in its as-supplied state is not satisfactory as drinking water, and good tasting water and safe water are required.
Further, water quality differs depending upon the water source, and taste also differs depending upon the water source. Therefore, recently, water other than drinking water also is activated to provide functional water, or impurities are strictly eliminated from water to make super purified water, and such water frequently is used in accordance with common usage.
In such circumstances, when water is processed to improve its functionality, and when difference in taste is inspected, the functionality cannot be improved effectively and, in many cases, the difference cannot be attributed only from a pH test of water using a pH meter, an electrical conductivity test of water using an electrical conductivity meter, or a chemical analysis for individual components in the water.
According to the present invention, ions present only in a small amount in a liquid are divided into positive ions, negative ions, and liquid charge density, and are measured. It is an aspect of the present invention to provide a detecting and analyzing apparatus for positive ions and negative ions in a liquid, which is capable of displaying the measured values, and storing data concerning the measured values.
SUMMARY OF THE INVENTION
A detecting and analyzing apparatus for positive ions and negative ions in a liquid of the present invention comprises:
a sensor section having a collector electrode,
a signal detecting section for outputting a signal which is proportional to an amount of ions in the liquid contacting the collector electrode,
a container for accommodating the liquid to be measured, and
a measuring body, wherein
the measuring body processes the signal output from the signal detecting section, thereby displaying in accordance with an amount of detected ions, storing data of detected ion amount, and outputting impressed voltage to the sensor section.
According to the invention, voltage, waveform, frequency, and the like of impressed voltage for the sensor in the detecting and analyzing apparatus are varied and used, and it is possible to check a degree of collection of positive ions and negative ions in the liquid. With this feature, it is possible to check, stepwise, what kind water is easily treated, and what kind of water is easily made as good taste water.
According to the invention, it is possible to measure trace quantities of positive ions, negative ions, and charge density present in any kind of water. Any kind of water includes,
1) long-standing water of a first embodiment, which exists in various locations, while always changing its appearance,
2) water having components which vary largely depending upon its source,
3) water prepared artificially and including chemical components or the like, and it becomes further difficult to check the water quality depending upon the analysis and the like of the chemical components, and
4) water in which measured values often vary and it is very difficult to repeat the measurements of the components because the water greatly includes gas, the water is evaporated at its surface and gas in the air enters the water.
With such a measurement, it is possible to indicate the cause of water activation and nature of taste in water in terms of amount from a direction different from chemical measurements which are divided to various current elements.
A concrete structure of the detecting and analyzing apparatus for positive ions and negative ions in a liquid of the present invention comprises:
a signal detecting box including therein a sensor section having a coaxial cylindrical structure disposed in an upper portion of a body, a signal detecting section for outputting a signal which is proportional to an amount of ions in the liquid contacting a collector electrode, and a hoisting and lowering bench disposed in a lower portion of the body for hoisting and lowering the container in which liquids to be measured are accommodated with respect to the sensor section, and
a measuring body for displaying in accordance with an amount of detected ions, storing data of detected ion amounts, and outputting impressed voltage to the sensor section.
It is preferable that the signal detecting box and the body of the measuring body constituting the apparatus are both constructed of a metal.
Preferably, the detecting and analyzing apparatus includes a means for controlling a temperature of the liquid to be measured.
For example, the sensor section of the signal detecting box is disposed in the upper portion of the body such that the sensor section directs downward, and the hoisting and lowering bench is moved up and down by rotating a knob mounted to the hoisting and lowering bench.
It is desirable that the detecting and analyzing apparatus is provided in its body of the measuring body with an amplifying circuit of the detected signal, a digital data display circuit, a data record outputting circuit, an impressed voltage generating section for the sensor, a zero-correction adjusting circuit, a sensitivity adjusting circuit, a measurement starting circuit, an automatic/manual switching circuit, and an impressed voltage switching circuit for a manually operating sensor.
In the detecting and analyzing apparatus for positive ions and negative ions, for example, a zero adjustment is performed in air before a liquid to be measured is placed on the hoisting and lowering bench. Thereafter, the hoisting and lowering bench is lowered and the container (beaker) in which the liquid, i.e., the object to be measured, is contained, is placed on the hoisting and lowering bench. Then, the knob is rotated to hoist the hoisting and lowering bench, thereby inserting an ion detecting section of the sensor into the liquid in the container, and the hoisting and lowering bench is stopped at a predetermined position.
The power of the measuring body is turned on, and the measurement starting switch is turned on. Then, the measurement is automatically started, and measurements of positive ions, charge density in
