Description

BRIEF DESCRIPTION OF DRAWINGS

[0005] The technical solution is further explained in FIG. 1, showing the cross-section guided by the optical axis of the turbidimetric channel, and FIG. 2, which is a cross-section guided by a plain of turbidimetric and nephelometric axes of the device.

Made for Carrying out the Invention

[0006] An example is a device for measuring the concentration of organic substances in the water rinse during cleaning electronic assemblies on printed circuit boards from flux residues after soldering. It consists of body 11 of the device, attached to reductions 2 with a seal for mounting cuvette 3. The cuvette 3 is made from a material that does not absorb UV radiation. Cuvette 3 is exchangeable for cuvettes of a different size of the optical path of the UV beam in the sample. The measured sample of liquid flows through inlet 8 and out through outlet 5. In the body of device 11, there is a cavity for installing ultrasonic sonotrode 1. The sample stream is intensively oscillated by sonotrode 1, and while oscillating, it enters the measuring cuvette 3. The powerful ultrasonic field also extends to cuvette 3 and has two functions. It cleans the walls of transparent cuvette 3 from possible deposits of dissolved residues that fall out of the emulsion and, as insoluble in water but highly sticky, settle on the walls and transparent parts of cuvette 3. At the same time, it increases the emulsification of the sample to the maximum possible level, thus ensuring repeatable concentration reading values.

[0007] UV light sources 6, 7 with the appropriate wavelength 21, 22 illuminate the cuvette 3 with a sample. Wide-spectrum photodiode 4 senses a signal partially absorbed by the sample (Turbidimetry). The reference broad-spectrum photodiode 9, which senses the momentary intensity of UV sources, is positioned so that rays from sources 6, 7 illuminate them directly outside cuvette 3. Perpendicularly to the optical axis of the UV light sources 6, 7 and sensor 4, a broad-spectrum photo sensor 10 is placed, which senses any reflection from the liquid droplets of the emulsion or solids. (Nephelometry).

[0008] The same configuration can be used to measure raw water before processing into drinking water or treated wastewater after passing through a treatment plant. The measured liquid sample flows through inlet 8 into the cuvette 3 and through outlet 5 from the device. UV light sources 6, Z with the appropriate wavelength Al and 22 illuminate the measuring cell 3 with the sample. Cuvette 3 is made of a material that does not absorb the radiation of the corresponding wavelength. The ultrasonic field is applied to the measured sample by the sonotrode 1 directly in front of the measuring cuvette 3. In this application, the primary function of ultrasound is to clean the cuvette from the deposit of organic substances and algae growth.

[0009] Broad-spectrum photodiode 4 senses a signal partially absorbed by the sample. (Turbidimetry). The reference broad-spectrum photodiode 9 is positioned so that the rays from sources 6, 7 illuminate them directly outside the cuvette 3. Perpendicularly to the optical axis of the UV light sources 6, 7 and sensor 4, a broad-spectrum photodiode 10 is located, which senses any reflection from liquid droplets of the emulsion or solids for nephelometric measurement.

Industrial Applicability

[0010] According to this technical solution, equipment for measuring organic substances in water in the form of genuine solutions or emulsions is usable in the water treatment industrytreatment of raw water to a higher quality or wastewater treatment for monitoring the quality of output water. It can be used to monitor the quality of water rinses in cleaning processes in the electrical and mechanical industries. It applies to all kinds of monitoring organic substances in water where there is a risk of dissolved impurities falling out of the solution or emulsion and deposition on the walls and optical path of the measuring device.
