Technical field:
The present invention relates to water quality on-line monitoring instrument, in particular, relate to a kind of water quality on-line monitoring instrument intelligent digestion controller.
Background technology:
Traditional water quality on-line monitoring instrument, mainly measure water sample with dichromate titration, its operating process is: at first by manually add quantitative potassium dichromate in water sample, and under strong acid condition, be catalyzer with the silver salt, clear up through high temperature, be indicator then with the ferroin, iron ammonium sulfate be titrated in the water sample by hand that oxygen consumption organic in the water sample and reducing substances are with Cr6
+Be reduced to Cr3
+, and the dichromate that is not reduced is converted into by the amount of the iron ammonium sulfate that consumes and consumes the mass concentration of supporting.
Shortcomings such as dichromate titration manual operations digestion instrument mainly includes heating arrangement, reflux and acid titration apparatus, and this digestion instrument exists test period to grow, manual testing result is inconsistent, the measurement result deviation is bigger.
Summary of the invention:
The shortcoming long at existing water quality on-line monitoring instrument manual operations test period, that manual testing result is inconsistent, the measurement result deviation is bigger the object of the present invention is to provide a kind of intelligent digestion controller of novel water quality on-line monitoring instrument.
For achieving the above object, the present invention is mainly by the following technical solutions:
A kind of water quality on-line monitoring instrument intelligent digestion controller, include central processing unit, seal casinghousing and shield shell, chemical reactor and photoelectric detector are installed in the middle of described seal casinghousing and the shield shell, described photoelectric detector detects water quality detection process in the chemical reactor, and the output electric signal is detected by the amount of central processing unit to the dichromate that consumes in the chemical reactor to central processing unit.
Described photoelectric detector comprises photoemitter and photelectric receiver, and described photoemitter and photelectric receiver lay respectively at the both sides of chemical reactor.
One heating and cooling device is installed, with the temperature of reaction of control chemical reactor on the described chemical reactor.
Described heating and cooling device also is connected with a Temperature Detector, is used for the detected temperatures signal, sends central control unit to and carries out analyzing and processing.
The present invention detects the water sample reaction process in the chemical reactor by photoelectric detector, and converts light signal to electric signal and send to the water quality on-line monitoring instrument central processing unit and handle, and then result is shown.Compared with prior art, the present invention has simple to operate, detects quick and precisely the safe operation process advantages of higher.
Description of drawings:
Fig. 1 is a digestion controller inner structure synoptic diagram of the present invention.
Identifier declaration among the figure: seal casinghousing 1, chemical reactor 2, photelectric receiver 3, photoemitter 4, heating arrangement 5, heat sink 6, Temperature Detector 7, shield shell 8.
Embodiment:
Core concept of the present invention is: water sample to be detected, oxygenant, catalyzer, screening agent and strong acid media are placed in the chemical reactor, then by the heating and cooling device heating, accelerate it and produce chemical reaction, to shorten measuring period; By Temperature Detector its temperature of reaction is detected simultaneously, and control by central processing unit, after question response finishes, photosignal is changed into the central processing unit that electric signal sends water quality monitor to, the amount of dichromate that instrument consumes is detected by photoelectric detector.
For setting forth thought of the present invention and purpose, the present invention is described further below in conjunction with the drawings and specific embodiments.
See also shown in Figure 1ly, the invention provides a kind of water quality on-line monitoring instrument intelligent digestion controller, it mainly is to add quantitative potassium dichromate in water sample to be detected, and then utilizes oxygen consumption organic in the water sample and reducing substances with Cr6
+Be reduced to Cr3
+Thereby, calculate the amount of oxygen consumption organic and reducing substances in the water sample, draw the pollution condition of water sample, with the accuracy of the online detection of increasing water quality with shorten time of water sample detection.Here said water quality on-line monitoring instrument intelligent digestion controller is controlled by the water quality on-line monitoring instrument central processing unit, it mainly includes seal casinghousing 1 and shield shell 8, wherein seal casinghousing 1 is fixedlyed connected with shield shell 8, and also is installed with chemical reactor 2, photelectric receiver 3, photoemitter 4, heating arrangement 5, heat sink 6 and Temperature Detector 7 in its two inside.
Wherein said chemical reactor 2 is mainly used in the place that a generation chemical reaction is provided for oxygenant, catalyzer, screening agent, water sample and strong acid media mixed solution; The effect of heating arrangement 5 is to be the heating of the mixed solution in the chemical reactor 2, and its heating-up temperature is advisable at 160 to 175 degrees centigrade, helps the process of chemical reaction, shortens measuring period; The effect of heat sink 6 is after chemical reaction is finished or heating-up temperature is lowered the temperature rapidly by heat sink when too high.
Because the reaction process of mixed solution has bigger association with temperature in the chemical reactor 2, therefore the temperature of reaction of mixed solution there is the requirement of comparison strictness, and heating arrangement 5 and heat sink 6 are in the process of heating and cooling, the adjustment of temperature directly has influence on water sample detection result's accuracy to the temperature of reaction of mixed solution, therefore need detect by the temperature that 7 pairs of heating arrangements 5 of Temperature Detector and heat sink 6 are produced, and the data that will detect gained send in the water quality on-line monitoring instrument central processing unit, carry out Treatment Analysis by the water quality on-line monitoring instrument central processing unit, with control heating or cooling.
In addition, for detecting the concrete condition of water sample, be separately installed with photelectric receiver 3 and photoemitter 4 in the left and right sides of chemical reactor 2, by photoemitter 4 the pairing light signal of the reaction process in the chemical reactor 2 is sent to photelectric receiver 3, photelectric receiver 3 converts this light signal to corresponding electric signal and sends in the water quality on-line monitoring instrument central processing unit then, is detected by the amount of central processing unit to the dichromate that consumes in the chemical reactor.
More than be that a kind of water quality on-line monitoring instrument intelligent digestion controller provided by the present invention is described in detail, used specific case herein structural principle of the present invention and embodiment are set forth, above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
