Description
Technical field
What the present invention relates to is a kind of station boiler flyash carbon content on-line testing apparatus, particularly a kind of carbon testing device adapting to various coal blending, a kind of isokinetic sampling of employing with sample the sampling mode combined from odd test, the method calcination utilizing high-frequency electromagnetic to heat, and by being close to non-maintaining one dimension mechanical transmission, complete the online carbon testing device of electromagnetism calcination method flying dust of one-dimensional mode of the sampling to flying dust, calcination, weighing measurement continuously.
Background technology
At present, external conventional carbon testing device belongs to " cold ash sample microwave measurement ", and its method gathering flying dust gathers after carrying out bypass cooling to the flying dust in flue or directly gathers the ash sample in ash bucket.And domestic many employings " hot ash sample microwave measurement ", the flying dust gathered is the heat ash in flue, and its acquisition method has impacting type to sample and Venturi tube isokinetic sampling.In application aspect, due to the feature that flying dust temperature high flow rate is fast, measuring equipment is easily caused to occur getting grey pipeline condensation and blocking, therefore measuring equipment is difficult to the requirement reaching user in measuring accuracy and maintenance, in addition, microwave carbon determination can not adapt to the flying dust carbon determination requirement under the many coals burning of domestic fuel-burning power plant.
In recent years, the calcination loss method flying dust carbon determination researched and developed by continent, former Nanjing Zhong electricity company put into operation in power plant, and calcination method carbon determination can adapt to the change of coal, and measuring accuracy is higher.After Continental AG stops production, technology is lost to the producer that forms a complete production network completely, and the product of the Company that the personnel walked out from Continental AG successively establish is the product purchasing supporting producer mostly, wherein only has a company to be transitioned into independent production.Although improve to some extent to original system design, but mainly to the improvement of materials application aspect, on the whole, new breakthrough is not had at technical elements, especially in physical construction, still the physical construction (see figure 7) of " three dimensional pattern " has been followed, its transmission needs the circumferential transmission of rotating disk moving up and down to assist a ruler in governing a country again and crucible could be delivered to corresponding measurement point with the displacement movement of interlock in conjunction with hoistable platform, also need an independently ash discharge pipeline, and a Resistant heating stove uninterruptedly heated, measurement is complicated and reliability is low, failure rate is very high, almost be difficult to ensure to measure failure-free operation 1-2 month at the scene, we can say, calcination carbon testing device online at present, there is no a measuring equipment that can deserve to be called in practical application meaning.
Summary of the invention
What the present invention proposed is the online carbon testing device of a kind of dimension orthoscopic electromagnetism calcination method flying dust, its objective is for above-mentioned application present situation, gearing structure is improved to simple and direct reliable " one-dimensional mode "; Advanced high-frequency electromagnetic incinerator is adopted to replace original Resistant heating mode; The increase of transformation stopple coupon from taking out system, and devises the receipts ash module port integrated with ash discharge, eliminates independently ash discharge pipeline, utilizes on-the-spot compressed air for instrument, and the method combined with suction ash by blowing ash realizes quick ash discharge.Reliable mechanical transmission and rapid combustion technology and high-accuracy weighing technology, in conjunction with computer disposal, really accomplish detection real-time online.
