Description
Technical field
The utility model relates to a kind of measurement mechanism of flue dusty gas, especially flue dusty gas probe.
Background technology
At present, people often use direct air extractor for the dusty gas in the flue is measured, it by be located at inserting tube in the flue and flue outer heat tracing pipeline, dedusting, dewater, firing equipment constituted.During detection, the precision of measuring for guaranteeing, the flue gas that inserting tube is extracted out is removed wherein dust and moisture by heat tracing pipeline transportation to dedusting, water removal device, send measuring instrument to detect after by firing equipment flue gas being warming up to temperature in the flue again.But, this device exists many deficiencies, at first, for prevent dust, moisture content in the flue gas in gas circuit cohesion and reach the requirement of surveying instrument to the flue gas cleaning degree, need long heat tracing pipeline that flue gas is caused dedusting, water removal device, make the cost of its manufacturing and use all very high; Secondly, flue gas is in dedusting, the process that dewaters, and the many gases that include can be dissolved in water, or react to each other, and this will produce bigger influence to measuring accuracy thereafter; Once more, the firing equipment that flue gas is warming up to temperature in the flue has also increased the cost of making and using; The 4th, the high temperature in the flue, the circumstances of high humidity make its flue gas that is drawn out of more make the operation of this device increase difficulty; The 5th, the direct discharging of the flue gas after the apparatus measures has also caused certain pollution to environment.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of flue dusty gas probe for overcoming weak point of the prior art.
The technical scheme that is adopted comprises the inserting tube of being located in the flue, particularly the port of inserting tube is serially connected with current-limiting components and dilution parts, said current-limiting components is that an end of filter chamber is equipped with filtrator, the other end is sound equipment aperture and external current limiting tube, said dilution parts are that an end of dilution chamber is equipped with current limliting spout and pressurized air spout, another termination detector tube, said current limliting spout and current limiting tube link, and said pressurized air spout and compressed air hose link.
As the further improvement of technical scheme, described filtrator is the coarse filter that places the interior fine filtrator of filter chamber port and its overcoat; The diameter of described sound equipment aperture is 3～8 microns; Described current limliting spout is 4, and be distributed in the pressurized air spout around; The overall diameter of described current limliting spout is 1～3 millimeter; The diameter of described pressurized air spout is 0.2～0.8 millimeter; The diameter of described pressurized air spout is 1 to 1.5～6 with the ratio of the diameter of columned dilution chamber; Described current-limiting components places in the calibration chamber of calibration parts, and a termination in said calibration chamber has gas sample introduction pipe, the other end to have the air inlet window; One termination in described calibration chamber has flue vacuum detecting pipe; Described current limiting tube is connected to dilution parts detector tube.
Beneficial effect with respect to prior art is, one, the current-limiting components of inserting tube port serial connection and dilution parts can be sucked out flue gas it under the unaltered situation of content, do not need again again to flue gas be incubated, dedusting and dewatering, reduced widely and made and the cost of operation; Its two, become bleeding of air pump and be the calming the anger of air compressor, make pressure in the pipeline all the time greater than the air pressure in the external world, guaranteed that the dilution ratio after the dilution can not change, and improved the dewpoint temperature of the aqueous vapor in the flue gas simultaneously, made it can not tie water, improved the precision of measuring; Its three, can be directly send surveying instrument to detect the flue gas of sucking-off, do not need again the expense of firing equipment and its use has been saved in the flue gas heating; Its four, because of the uptake of flue gas after the dilution is very little, as only need taking out 2～6 cubic metres flue gas in one month, so very little to the maintenance of itself and follow-up pipeline, the flue gas after the measurement is not needed otherwise processed yet; Its five, current-limiting components be placed in the calibration parts the calibration chamber in, make online calibration simple and easy to do.
Description of drawings
Below in conjunction with accompanying drawing optimal way of the present utility model is described in further detail.
Fig. 1 is a kind of basic structure synoptic diagram of the present utility model.
Embodiment
Referring to Fig. 1, the utility model of being located in the flue is made up of current-limiting components 1, dilution parts 2 and calibration parts 3.Wherein, to be built-in with filtrator 4, the other end that the coarse filter 41 of fine filtrator 42 and its overcoat constitutes be that diameter is 5 microns sound equipment aperture 12 and an external current limiting tube 13 to a port of the filter chamber 11 of current-limiting components 1.It is pressurized air spout 22, another termination detector tube 25 that 2 millimeters current limliting spout 21 and diameter are 0.5 millimeter that one end of dilution chamber 23 of dilution parts 2 is equipped with diameter.Aforesaid dilution chamber 23 is cylindric, and its diameter is 1.5 millimeters, and current limliting spout 21 links with current limiting tube 13, and pressurized air spout 22 links with compressed air hose 24.Current-limiting components 1 is placed in the calibration chamber 31 of calibration parts 3, and a termination in this calibration chamber 31 has gas sample introduction pipe 32 and flue vacuum detecting pipe 33, the other end to have air inlet window 34.Also be connected to dilution parts detector tube 26 on the current limiting tube 13.
During use, cleaning, clean pressurized air sprays into dilution chamber 23 from compressed air hose 24 via pressurized air spout 22, utilize siphon principle to make current limliting spout 21 places produce certain vacuum tightness at this pressurized air, this vacuum tightness provides power for flue gas from the suction of current-limiting components 1, it can make with flue in the high dirt of certain negative pressure was originally just arranged, produce a negative pressure reduction between the flue gas of high temperature and high humidity again, thereby make the flue gas that is full of calibration chamber 31 successfully enter filter chamber 11, and through sound equipment aperture 12 via coarse filter 41 and fine filtrator 42, current limiting tube 13 and current limliting spout 21 are inhaled into dilution chamber 23; And then be mixed into the very low flue gas dilution gas of flue gas concentration equably by the dilution ratio of determining and go out from detector tube 25, the surveying instrument that enters the back is for detection.Here, sound equipment aperture 12 is constrictions, when compressed-air actuated pressure greater than 6.89 * 10
4～1.38 * 10
5Behind the handkerchief, its exhaust gas volumn that flows through is constantly equal to a saturation value; And compressed-air actuated flow is directly proportional with pressure, by controlling compressed-air actuated pressure, just can control the dilution ratio of the flue gas in the dilution chamber 23 well.The air pressure of general air compressor output is 4.13 * 10
5～6.20 * 10
5Handkerchief is at least 1.38 * 10
5～4.13 * 10
5Handkerchief is adjustable, so can be 20～400 to 1 in the dilution ratio of this section adjusting.
Before measurement, if need instrument is calibrated again, only need to send into calibration gas the calibration gas after can obtaining to dilute by detector tube 25 places by gas sample introduction pipe 32.
