Description
Technical field
The utility model belongs to quantitative chemical analysis field, be specifically related to a kind of external application heating watt digestion pool.
Background technology
Current most water quality monitoring surveying instrument, as ammonia nitrogen quantitative chemical analysis, mostly adopts the method for physioptial photo measure.Spectrophotometric method is the common method that chemical analysis is measured, and is also the common method of monitoring water quality on line surveying instrument.The principle of spectrophotometric method uses the langbobier law in physical optics: Lambert-Beer law: when a branch of collimated monochromatic ligth is by uniform non-scatter sample, sample is directly proportional to the concentration of sample and thickness to the absorbance of light, A=ECl.In actual use, langbobier law application is very limited, and reason is that sample is very little to the absorbance of light.Be measured as example with the ammonia nitrogen of water, it use the method for the dyeing of chemistry and the spectrophotometry of physics.Usually, the extinction feature of measured liquid water pollutant ammonia nitrogen is unconspicuous, spectrophotometric method cannot be used to measure, therefore measure and first will select chemical staining methods: because the ammonia in the alkali lye of potassium iodide mercuric iodixde and water can generate light red brown colloidization compound, this compound has strong light absorption at 410-425nm, Here it is cytochemical staining procedure.Secondly, use the spectrophotometric method of physics: the light selecting applicable wavelength (absorbing wavelength=410-425nm after ammonia nitrogen dyeing) according to measured object, measured sample is directly proportional to the concentration of sample and thickness to the absorbance of light.Quantitative light intensity, through the Analysing cuvette " thickness is certain " that measured liquid is housed, light intensity weakens because of strong absorption.Again, measure the light intensity after by Analysing cuvette, because the light path of Analysing cuvette is constant, photon absorbing intensity is directly proportional to the concentration of the pollutant load (ammonia nitrogen) of measured liquid, therefore measures light intensity, is just aware of the content of water quality pollutant ammonia nitrogen.As can be seen here, use spectrophotometric method to measure and pollute, chemical staining is a step of most critical.Chemical staining and colorimetric spectrophotometric method need certain temperature conditions, and therefore digestion pool needs heating.How to heat? existing heating means add resistance wire outside digestion pool, energising resistance wire heating heating and decompose pond.This resistance wire spot heating can cause digestion pool thermal stress phenomenon to assemble, and digestion pool may be caused time serious to break.Same this resistance wire spot heating also can bring digestion pool inner sample to heat non-uniform phenomenon, affects titer curve offset, causes measuring error.The utility model is attempted to set up rapid and uniform heating technology and is solved prior art problem.
Utility model content
The technical solution of the utility model: the digestion pool of a kind of external application heating watt, comprise each one and half barrel-shaped external application heating watt around, columned digestion pool and circle jump ring, it is characterized in that, as shown in Figure 1, centre is columned digestion pool, and the right and left respectively has one and half barrel-shaped external application heating watt, the inside radius of half barrel-shaped external application heating watt is identical with the external radius of cylindric digestion pool, and the outside that half barrel-shaped external application is heated watt is 4 round jump rings.
The digestion pool of described a kind of external application heating watt, it is characterized in that half barrel-shaped external application heating watt is watt body made by insulator, sprayed coating one deck conductive metal film on the interior semi circular surface of half barrel-shaped external application heating watt, respectively there is a metal conducting electrodes at the two ends up and down of half barrel-shaped external application heating watt, metal conducting electrodes electrical connection conductive metal film, applies one deck dielectric film in the outside of conductive metal film.
The digestion pool of described a kind of external application heating watt, is characterized in that a symmetrical light hole is respectively left in the centre of the external application heating barrel-shaped in left and right two and half watt, and the line of the line of its light hole and the luminotron of digestion instrument, photodetection window coincides.
Principle of work summary of the present utility model: under the tension force effect of 4 round jump rings, two and half barrel-shaped external application heating watt keep close contact with digestion pool, after the upper/lower electrode of two and half barrel-shaped external application heating watt switches on power, external application heating watt Quick uniform heating, heat, by digestion pool outer wall homogeneous heating sample, meets the requirement of chemical staining to temperature.The line of the light hole that the centre being exactly again two and half barrel-shaped external application heating watt stays is corresponding with the line of the luminotron of digestion instrument, photodetection window, meets spectrophotometer measurement requirement.
The beneficial effect of the digestion pool of a kind of external application of the utility model heating watt is homogeneous heating, controllable temperature, and temperature hold-time is long, and fast, the thermal efficiency is high, energy-conservation, the flames of anger, safety.
