Description
Technical field
The utility model relates to the flue gas analysis system, especially at the flue gas analysis system of the sintering machine flue of metallurgy industry.
Background technology
Two kinds of flue gas monitoring methods of the general employing of the continuous on-line monitoring system of domestic present flue gas, a kind of is the complete extraction method continuous monitoring of flue gas, another is the continuous monitoring of dilution extraction method.
Extraction method is the most traditional flue gas continuous analytical method fully, its method is that tested flue gas is extracted continuously fully, be transported to the analysis room and carry out two stage treatment through sampling probe primary filter, heat tracing, two stage treatment comprises that links such as condensation dehydration, fine filtering, gas distribution deliver to different gas analyzers and analyze, this method is the most popular at home, its advantage is that the pretreatment system principle is simple, and is easy for installation.Weak point is because flue gas contains a large amount of sulphuric dioxide, flue dust and moisture, probe segment and sampling pipe scale formation are serious, owing to becoming, moisture absorption sulfur in smoke in condensation process contains the acid solution body simultaneously, make the smoke components loss, cause the monitoring parameter distortion, make equipment corrosion simultaneously, acceleration equipment is aging, pretreatment system later maintenance workload is big after operation a period of time, and the core meter life is short, problems such as operating cost height.
The dilution extraction method is to utilize to penetrate to inhale principle analyzed gas is diluted extraction, dilution ratio is generally about 1:100, can reduce complicated sample pretreatment system in the extraction process like this, the advantage of this method is through the gas humidity after the dilution, content of sulfur dioxide and smoke content are all very low, two stage treatment through the analyzed gas after the dilution sampling requires very low, almost can directly analyze, infringement to the core analysis instrument is very little, weak point is that dilution probe making accuracy requirement is very high, pretreatment unit nearly all has been placed on probe segment, because dilution probe also needs to regularly replace filtration unit and cleaning, cause the daily servicing difficulty very big, and need have very high maintenance experience and knowledge frequently is finished maintenance work.
The utility model content
Technical problem to be solved in the utility model provides that a kind of probe designs is simple, cost of manufacture is low, is convenient to the external dilution extraction method flue gas analysis system of daily servicing.
For solving the problems of the technologies described above, the utility model comprises probe segment, pretreatment system and gas analysis system, and described probe segment comprises stopple coupon, coarse filtration net and mounting flange; Described pretreatment system comprises secondary filter, two solenoid valves of M1 ~ M4, dilution critical-sampled device, vacuum generator, accelerator, accurate filter.
In the such scheme, described pretreatment system also comprises the condensed water outlet device, and is arranged in the external flue gas pre-service case.
In the such scheme, described gas analysis system comprises gas distribution member, sophisticated processor and analyser.
In the such scheme, described gas distribution member is used for that the flue gas that the scene extraction comes is distributed to different analysers to be analyzed, and the afterbody that described sophisticated processor is used for flue gas becomes divisional processing, and described analyser is used to analyze the composition of flue gas.
In the such scheme, the flue gas that described probe segment extracts is connected to two solenoid valves of M4 in the flue gas pre-service case; Two solenoid valves of described M1 and M2 are used to control gas and purge gas enters system and is connected to secondary filter, two solenoid valves of M3 are used for the waste gas of blowback and impurity are discharged to outside the pre-service case, and two solenoid valves of M4 are used to connect the flue gas that described probe segment extracts; Described dilution critical-sampled device is used to dilute and controls dilution ratio through the secondary filter supplied flue gases; Described vacuum generator is used for the flue gas Automatic Extraction in the dilution critical-sampled device to accelerator; Described accelerator is used to improve the speed of smoke sampling, reduces systematic sampling retardation time; Described accurate filter is used for reducing once more the concentration of flue gas particles, thereby satisfies the requirement of analyser to smoke components; Described condensed water outlet device is used to reduce the water cut of flue gas and delivers to gas analysis system by gas path pipe.
The utility model is easy to dismounting owing to because the inner most of components and parts of will popping one's head in decompose in the dilution sampling cabinet of flue outside, be convenient to very much the monitoring and the fault judgement of maintainer to the sampling of sample gas, makes things convenient for handling failure; Owing to adopted automatic back blow, the conventional maintenance cycle stretch-out that makes this system can guarantee system's operation automatically for a long time, and failure rate is reduced greatly to weekly simultaneously.
Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.
Fig. 1 is the pretreatment system schematic diagram.
Embodiment
As shown in Figure 1, flue gas 12 in the flue filters through one-level by sampling probe 10, be transported to the filter element of secondary filter 9 again through two solenoid valves 18 of M4, the particulate size in the flue gas reduces, and the smoke content in dilution critical-sampled device 6 in the flue gas further reduces; Two solenoid valves of described M1, M2 15,16 are used to control gas 5 and purge gas 7 enters system and is connected to secondary filter 9, and two solenoid valves 17 of M3 are used for the waste gas and the impurity of blowback are discharged to outside the pre-service case; The zero air 1 of certain pressure produces the negative pressure of certain pressure by vacuum generator 2, vacuum generator 2 utilizes purification of compressed air to produce negative pressure, extract flue gas, the critical aperture of dilution critical-sampled device 6 is through grinding, the flue gas dilution ratio is controlled in the certain proportion, the flue gas Automatic Extraction in the dilution critical-sampled device 6 is arrived accelerator 14; Accelerator 14 is responsible for improving the speed of smoke samplings, reduces systematic sampling retardation time; Accelerator 14 unnecessary waste gas are discharged into the outside of sampling cabinet 6 by exhaust pipe 4, other one tunnel flue gas that need analyze is transported to accurate filter 8 by gas circuit, accurate filter 8 is responsible for reducing once more the concentration of flue gas particles, thereby satisfies the requirement of analyser to smoke components; Flue gas through three-stage filtration is delivered in the condensed water outlet device 11 by gas circuit, after condensed water outlet device 11 reduces the water cut of flue gas, delivers to the instrument cabinet of analysis meter chamber by gas path pipe 13.
