Detailed description of the invention
Below in conjunction with the drawings and specific embodiments further illustrating the invention.
As shown in Figure 1, the oil smoke of the invention quickly detects equipment and is divided into two parts, a part is for measuring flue gas flow velocity and extracting the front end measuring instrument of oil gas microparticle, including a body 6, one extension bar being hinged on body 63, extension bar 3 is withstood by a touch force sensor 4 on body 6, and extension bar 3 other end is clamped with a board-like extraction sheet 1 by a clamping device 2, additionally also has a temperature sensor 5 being connected with the body of measuring instrument.
Another part is the measurement main frame being analyzed processing, (it is cpu including a RF transmitter generator, infrared sensor, chopper, signal processing circuit and micro processor, integrated approach herein), infrared sensor is connected to micro processor by signal processing circuit, having chopper and wavelengthtunable filter set between infrared sensor and RF transmitter generator, filter set has at least one optical filter.
Measure main frame and include the infrared photometry instrument of a micro processor (cpu) and a multi-wavelength, infrared photometry instrument is made up of a steady optical circuit, RF transmitter, semicircle chopper, wavelengthtunable filter set and infrared sensor, the scopes such as RF transmitter sends stable infrared ray under the support of steady optical circuit, its wavelength covering 3.4 μm, 3.8 μm, 3.1 μm, 2.2 μm.Infrared ray becomes pulsation infrared ray after the semicircle chopper of over-rotation, pulsation infrared ray is through the extraction sheet being adsorbed with oil gas microgranule, with the light directive infrared sensor of certain wavelength after the optical filter of filter set, result is exported micro processor by infrared sensor, obtains oil smoke on different wave length and extracts the absorbance of sheet.Temperature, flow and pipeline area that front end measuring instrument records are input to micro processor be digitized processing simultaneously, show and print the measurement result of discharge oil smoke total amount in a period of time.Infrared filter group has several optical filters, one of them wavelength is positioned at 3.4 μm of oil gas particulate absorbent peak, measure the absorbance of oil gas granule, other wavelength 3.8 μm, 3.1 μm, 2.2 μm etc. for reference, get rid of the interference of the chaff interferences such as moisture, solid particle, carbon dioxide in flue gas, obtain the measurement of oil smoke amount accurately.
Described wavelengthtunable filter set is provided with several optical filters, can pass through 3.4 μm, 3.8 μm, 3.1 μm, the infrared light of 2.2 mum wavelengths respectively.Wherein 3.4 mum wavelengths are for measuring the absorbance of oil gas granule, and other wavelength is used for reference, get rid of the interference of water, solid particle and carbon dioxide in flue gas, accurately to obtain the content of oil gas microgranule.Certain optical filter is adjusted to other wavelength also dependent on needs.
As Figure 2-3, front end measuring instrument is extracted sheet 1, touch force sensor 4 and temperature sensor 5 by an extension bar being hinged on body 63, oil smoke and forms, extraction sheet 1 is clamped by extension bar 3 by a clip clamping device 2, extension bar 3 is withstood by touch force sensor 4, and touch force sensor 4 and temperature sensor 5 access measuring instrument.Oil smoke extract sheet 1, extract holder for x-ray film 2, extension bar 3 gravity provided support by touch force sensor 5.When flow of flue gas in flue 7, the upwardly directed dynamic pressure that fluid produces offsets part gravity, touch force sensor 4 measure the change exerted oneself, thus calculating the flow velocity of flue gas.Small oil particles in flue gas is also adhered on oil smoke extraction sheet 1 simultaneously.Extract the oil smoke amount adhered on sheet 1 and depend on the concentration of oil smoke in flue gas.Additionally, portion of water, Solid micro etc. also can stick on extraction sheet.The temperature in flue is measured in temperature sensor 5.Oil smoke is accumulated on extraction sheet, and temperature and flow velocity are recorded in the memorizer of front end measuring instrument body.
The oil smoke of the invention quickly detects equipment and adopts dry method directly to place velocity measurement sensor and corresponding dry type oil smoke in flue to extract sheet, then is put into by extraction sheet in portable main machine and directly measure oil smoke cumulative amount.By the correction algorithm of velocity of flue gas, obtain accurate oil smoke total amount.And this correction algorithm need not manually calculate, analyzer can show result after automatically calculating.As it is shown in figure 1, in sum, the oil smoke of the invention quickly detects equipment and can realize existing speed and accurately measure.The on-the-spot accumulative oil smoke discharge amount showing, printing certain smokejack of certain period of time.
Above an embodiment of the invention is described in detail, but described content has been only the preferred embodiment of the invention, it is impossible to be considered the practical range for limiting the invention.All equalizations made according to the invention application range change and improvement etc., all should still belong within the patent covering scope of the invention.
