The present invention relates to an on-line turbidity measuring device, and in particular, by supplying a sample water to be measured at a constant flow rate and flow rate, turbidity can be measured under a constant condition, and the flow or state of the sample water can be checked, and it acts as a variable on the measured value. Accurate measurement values can be obtained by removing bubbles generated during the supply of sample water, while calibration and turbidity measurement can be performed without a separate device or facility, and the values of washing and turbidity measurement of measuring instruments through high pressure injection are low range. Online turbidity measuring device that can be widely measured from high to high range.

In general, turbidity is a quantitative indicator of the cloudiness of water and also refers to the resistance to light passage.

This, turbidity is caused by a variety of suspended solids and the size ranges from colloidal dispersion to coarse dispersion.

In addition, turbidity is generated by extremely fine dispersoids, such as colloidal dispersion, in which water in a relatively stagnant state, such as lakes, is mostly generated by coarse dispersoids in water flowing in river water.

In addition, turbidity-inducing substances vary widely from pure inorganic materials to mainly organic organic materials, and in particular, large amounts of inorganics from natural organic rooms or factory wastewater and domestic sewage from pure inorganic materials such as earth and sand. Bacteria, microorganisms and algae generated by substances, organic substances and organic substances also act as substances causing turbidity.

In addition, the unit of turbidity is as follows.

 1. NTU (Nephelometric Turbidity Unit): A unit for measuring turbidity using a nephelometer. The scattered light is measured at 90 degrees of incident light to indicate the relationship between scattered light and turbidity (quantified amount). (The measure of turbidity, which was revised on February 1, 1999 in terms of drinking water, is measured in NTU units.

2.PPM (Parts Per Million) or Kaolin Standard Turbidity: The minimum content of ppm is also used in degrees (°), and the degrees (˚) are measured units measured by kaolin standardized photospectrometer and photophotometer. .

3. Formazin Turbidity Unit (FTU): A method of measuring turbidity by using a nephelometer that adopts an infrared light source as a formazine turbidity unit.

4. FAU (Formazine Atenuation Units): Formazine Attenuation Unit used in water treatment. It is mainly measured at 0 ° scattering angle.

5. FNU (Formazine Nephelometric Units): Formazine nephelometric units used in water treatment, mainly measured at 90 ° scattering angle, according to ISO 7027.

6. American Society of Brewing Chemist (ASBC).

7.JTU (Jackson Turbidity Unit): It is a unit used when measured by Jackson turbidity unit system. When liquid is put into Mass-Cylinder with scaled Mass-Cylinder placed on a candle, the scale that the flame is displayed varies depending on turbidity. Use In general, 40 JTU is roughly equivalent to 40 NTU using the result of the visual method and the formazine standard in instrumentation.

8. EBC (European Brewery Convention).

9. TE / F (Tribungseinheit / Formazine): German formazine turbidity units are used.

The measurement principle of turbidity is that light travels along a relatively unobstructed path when light of irradiated infrared wavelengths passes through pure water. However, some distortion occurs when light is scattered by particles suspended in pure fluid. That is, light interacts with particles as they pass through a fluid containing suspended materials, and these interactions vary depending on the size, shape, color, and refractive index of the particles.

Looking at the measurement range of turbidity, the measurement of turbidity is measured in the range of 0 ~ 10NTU, the measurement of suspended solids (SS) can be measured in the low range of the high range, such as 0 ~ 1000 (5000) NTU As the unit used, NTU, ppm, mg / L,% unit, etc. may be used to represent the measured value.

In addition, when looking at the calibration method of the sensor unit 52 using the light emitting sensor 52 'and the light receiving sensor 52 "in a straight line, it is possible to remove foreign substances remaining in the turbidity measuring device 100 and other samples. After removal, calibration is performed so that the turbidity value is "0" using distilled water, and the inside of the cell block 51 is filled to perform span calibration (measurement range calibration) using a calibration solution (formazine).

That is, when distilled water is filled inside the cell block to irradiate the infrared wavelength through the light emitting sensor 52 ', the infrared wavelength is received by the light receiving sensor 52 "installed in line with the light emitting sensor 52'. The amount of the infrared wavelength irradiated by the light emitting sensor 52 'and the amount of the infrared wavelength received by the light receiving sensor 52 " must be the same to indicate that there is no abnormality in the sensor unit 52. At this time, the measured value is " 0 " It will be to use the distilled water in the absence of any foreign matter.

In addition, in the case of span calibration (calibration range calibration) using a calibration solution (formazine), for example, in order to measure a range of 0 to 10 NTU, a calibration solution of 20 NTU is created and the measurement range is measured up to 20 NTU. To make it possible.

However, when the amount of the infrared wavelength irradiated from the light emitting sensor 52 'and the amount of the infrared wavelength received by the light receiving sensor 52 "are not equal through the calibration operation, the surface of the lens 52d of the sensor unit 52 is not exposed. When foreign matter is deposited and the abnormality of the sensor unit 52 is determined, it is possible to simply replace the sensor unit 52 by determining whether or not the abnormality is present.

In addition, when foreign matter is deposited on the surface of the lens 52d of the sensor unit 52, the motor 63 of the cleaning unit 60 is operated to rotate the cleaning brush 64 one to two times by the operation of the motor 63. The surface of the lens 52d is cleaned to be used as the turbidity measuring device 100 that shows an accurate measurement value when there is no abnormality after retrying the calibration process.

In the above, the present invention has been illustrated and described with reference to certain preferred embodiments, but the present invention is not limited to the above-described embodiments, and the present invention is not limited to the spirit of the present invention. Various changes and modifications will be possible by those who have the same.

As described above, the present invention uses a regulator so that the sample water supplied from the supply pump for supplying the sample water is supplied at a constant flow rate and flow rate so that the sample water is supplied under conditions suitable for turbidity measurement to obtain accurate turbidity measurement values. In addition, by installing an overflow tube in the blister removal container, the structure is improved so that the change factor of the measured value due to the bubble is removed by removing the bubbles generated during the sample water filling in the blister removal container.

In addition, the cover and the tube is transparent acrylic material so as to determine the state of the sample water as well as the situation where the sample water is collected in the blister removal container and the cell block and moved through the tube has the effect of increasing the efficiency of the measurement.

In addition, the infrared wavelength irradiated from one light emitting sensor hits the contaminants of the sample water and receives a wavelength scattered at 90 °, so that the turbidity value can be measured and filled with distilled water and the measurement solution (formazine) and irradiated from the light emitting sensor The sensor receives the infrared wavelength in a straight line to calibrate the sensor unit, and the turbidity measurement and sensor calibration are performed without any equipment by using the sensor unit installed in one cell block. have.

In addition, in order to remove the foreign matter deposited inside the blister removing container and the cell block, water is sprayed at a high pressure to remove the foreign matter, and a drain valve is formed in the tube connecting the blister removing container and the cell block to remove the foreign matter. It can be discharged, so cleaning and maintenance are simple.
