Description
Technical field
The utility model relates to resource and environment technical field, particularly relates to a kind of CODCr water quality on-line monitoring instrument.
Background technology
CODCr water quality online analyzer used in existing field of Environment Protection, the general deviation of domestic pharmaceutical industry device measuring precision is comparatively large, along with the lengthening of service time, all can occur the phenomenons such as digestion pool seepage is corroded, gas leakage, and sampling system is easily stifled perishable; Higher and the accessory of overseas equipment prevailing price is to damage, and maintenance cycle is long, and parts price allows consumer be difficult to acceptance.
Utility model content
The utility model object is exactly the defect in order to make up prior art, provides a kind of.
The utility model is achieved through the following technical solutions:
A kind of CODCr water quality on-line monitoring instrument, include nine logical valve, multiple reagent bottle, infrared quantitative systems, clear up light-source system, peristaltic pump and PLC control system, described nine logical valves are connected with multiple reagent bottle respectively by multiple revolving valve, nine logical valves are also respectively with infrared quantitative system with clear up light-source system and be connected, described peristaltic pump is connected with infrared quantitative system, described infrared quantitative system with clear up light-source system and be all connected with PLC control system.
Described infrared quantitative system includes infrared light supply, quantitatively glass tube and simulating signal light control plate one, the quantitative glass tube of light transmission of described infrared light supply is irradiated to described simulating signal light control plate one, simulating signal light control plate one is connected with PLC control system, and the two ends of quantitative glass tube are connected with peristaltic pump and nine logical valves respectively.When in quantitative glass tube without the light transmission glass tube that infrared light supply during reagent water sample sends, signal input value simulation light control plate is about 1200 through amplifying output display, if liquid level just rises to light source place when there being liquid to be pumped down to quantitative glass tube, now signal is blocked by liquid level, signal be increased beyond 1600 or under be reduced to 800, PLC control system just thinks that equipment is drawn into reagent by quantitative system.Native system is arranged on above poly functional reagent selector valve, so that accurately errorless quantitative.
Described clear up that light-source system includes specific wavelength light source, clears up glass tube, heating arrangement and simulating signal light control plate two, the light transmission of described specific wavelength light source is cleared up glass tube and is irradiated to described simulating signal light control plate two, simulating signal light control plate two is connected with PLC control system, described heating arrangement is arranged on the outside of clearing up glass tube, be provided with High Temperature High Pressure at the top of clearing up glass tube and clear up valve, the lower end of clearing up glass tube is connected with nine logical valves.By peristaltic pump, quantitative system, nine logical valves, reagent injection is cleared up in glass tube, after reagent mixed liquor being heated to specific set temperature by heating system after band mixes, clear up the light that light source sends specific wavelength and pass through mixed liquor, mixed liquor after clearing up produces the material can crossed and absorb this wavelength light, and simulation light control plate receives and amplifies and absorbs front and back light signal.PLC control system goes out surveyed material concentration by program formulae discovery.
(mercuric sulfate can eliminate the interference of Chloride Ion In Water for water sample, potassium dichromate digestion solution, mercuric sulfate, because chlorion can form highly stable mercuric chloride with mercury ion), silver sulfate solution (silver sulfate adds can more effectively be oxidized straight chain fatty compound as catalyzer) mixed liquor is heated to 175 DEG C, after organism in dichromic acid ionic oxide formation solution, color can change, analyser detects the change of this color, and this change is converted into COD value exports out.The potassium dichromate ionic weight consumed is equivalent to oxidable organism amount.
The utility model has the advantages that: noiseless between the utility model each reagent water sample, pollution-free, make sample accurate, adopt infrared light supply and corrosion-resistant Wriggling Pump Head quantitative accurate, the vacuum insulation band that negative pressure is formed avoids reagent directly and the contact of pump line, thus extends the serviceable life of equipment.
