Summary of the invention
The present invention is in order to overcome above-mentioned deficiency, to provide a kind of working stability reliable, degree of accuracy, the high fuel oil apparatus for determination of carbon and hydrogen of accuracy, it utilizes same high-temperature cracking furnace, a special-purpose cracking tube, and detecting device, can realize carbon and hydrogen simple, measure fast.
The present invention is achieved through the following technical solutions goal of the invention: a kind of fuel oil apparatus for determination of carbon and hydrogen, formed by sample gasification cracking system, gas cleaning unit, carbon dioxide reforming unit, detection system, data Collection ﹠ Processing System and control system.Described sample gasification cracking system contains sample gasification furnace and high-temperature cracking furnace, special-purpose cracking tube and the sampling device of oxygen feedway, controllable temperature, and sampling device can be artificial sampling device, but also automatic sampling apparatus; Described gas cleaning unit contains the sulphur removal oxide device and denitrogenates oxide device; Described carbon dioxide reforming unit refers to that carbon dioxide changes into the device of water, and it comprises in the high temperature furnace, of a controllable temperature is equipped with conversion tube of lithium hydroxide etc.; Described detection system contains two electrolytic cells: first electrolytic cell be used for to be surveyed hydrogen, second electrolytic cell and is used for carbon determination (be used for surveying the hydrogen number of the water that carbon dioxide changes into, this measured value can convert the measured value of carbon by calculating to); Described data Collection ﹠ Processing System contains to be handled the acquisition process of the electric signal of two electrolytic cells, temperature signal collection.Described control system contains the control of electrolytic process control, data acquisition and the processing of sample auto injection, Control for Kiln Temperature, two electrolytic cells, and as calculated machine or single-chip microcomputer handle, the output measurement result.
In the said structure, the sample feeding device is sent into gasification furnace, the high-temperature cracking furnace of Pintsch process system, and pyrolysis furnace is laid cracking tube, and furnace temperature can reach 1000 ℃ under the excess oxygen, sample perfect combustion.Input was at first electrolytic cell that is connected with the cracking tube endpiece after products of combustion was removed sulfur oxide, and first electrolytic cell is connected with nitrogen removing device, is connected with the carbon dioxide reforming unit then, is connected with second electrolytic cell again.
The present invention compared with prior art has following good effect:
1, can detect volatile substances such as gasoline, diesel oil;
2, simple to operate, the data validity that detects gained is strong, and testing result is accurate;
3, the measuring process controllability is strong, detects easy, quick;
5, by computing machine or the whole testing process of Single-chip Controlling, handle and detect data, simple and convenient.
