Specific implementation mode
One of core of the utility model is to provide a kind of smoke sampling rifle, so as to add the method for constant speed according to grid Scientific and reasonable is sampled flue gas, while smoke inlet being effectively prevent to be blocked by flue dust.
Another core of the utility model is to provide a kind of fume component analysis system.
In order to make those skilled in the art more fully understand the utility model, below in conjunction with the accompanying drawings and it is embodied The utility model is described in further detail for mode.
Referring to FIG. 1, the smoke sampling rifle disclosed in the utility model, including pipe main body 11 and it is opened in pipe master Multiple smoke inlets 12 on the side wall of body 11, wherein one end of pipe main body 11 is closed, another end opening, and one end of opening is made For flue gas discharge opening, smoke inlet 12 should be distributed according to the requirement of gridding method in pipe main body 11, and so-called gridding method is just It is the grid cell for the cross section of flue being divided into multiple area equations, flue gas sample is extracted from the center of these grid cells Product, it is right in present specification since " gridding method " is known in fume component analysis field technology personnel and common method This is no longer repeated.In addition to this, the smoke sampling rifle disclosed in the utility model further includes dust-break raised platform around a well 16, the dust-break Raised platform around a well 16 is arranged in the outside of smoke inlet 12, and is raised in the side wall of pipe main body 11, specifically, as shown in Figure 2, dust-break Raised platform around a well 16 originates in the side wall of pipe main body 11, and extends along perpendicular to 11 axially direction of pipe main body.
It is found in practical sampling process, the dust in flue gas is easy the attached product near smoke inlet 12, eventually leads to cigarette The blocking of gas entrance 12.
And in the smoke sampling rifle disclosed in above-described embodiment, it is convex due to being provided on the outside of each smoke inlet 12 The dust-break raised platform around a well 16 of 11 side wall of pipe main body is arised from, dust-break raised platform around a well 16 can effectively stop the attached product of dust in flue gas in smoke inlet In 12, therefore avoiding problems the blockings of smoke inlet 12, to ensure that the accuracy of fume sample.
Certainly, the size of smoke inlet 12 can be determined according to the length of flue gas flow in pipe main body 11, it is generally the case that The flow of flue gas is longer, then the aperture of smoke inlet 12 is bigger;The flow of flue gas is shorter, then the aperture of smoke inlet 12 is smaller; In addition to this, the cross sectional shape of pipe main body 11 may be a variety of, such as round, rectangle or polygon, this practicality is new Recommend to use pipe in type embodiment.
In fact, the extraction speed of flue gas is also to require in sampling process, according to domestic and international boiler test standard, adopt To accomplish constant speed when being sampled with gridding method, so-called constant speed refer to just the fume extraction speed of each net region need at this Flue gas flow velocity it is consistent, for this purpose, in smoke sampling rifle disclosed in the present embodiment, be also provided with back pressure testing tube 17, Back pressure testing tube 17 is arranged on the side wall of pipe main body 11 combined with Figure 1 and Figure 2, and back pressure testing tube 17 enters positioned at flue gas The back side of mouth 12, consistent with pipe main body 11, back pressure testing tube 17 is also one section and closes the pipe fitting that the other end opens, and back pressure survey Back pressure test mouth is further opened on test tube 17, back pressure tests mouth with smoke inlet 12 in 11 axially direction of pipe main body It corresponds.
According to Hydrodynamics Theory, when 12 face flue gas flow direction of smoke inlet in pipe main body 11, smoke inlet 12 is measured Flue gas pressures difference between back pressure test mouth on back pressure testing tube 17 can calculate the mean flow rate of flue gas, this makes flue gas Sampling gun has flue gas speed measuring function.
In order to advanced optimize the technical solution in above-described embodiment, can also require to set according to gridding method in pipe main body 11 Temperature measuring equipment is set, specifically, temperature measuring equipment should be set close to smoke inlet 12 and with the one-to-one correspondence of smoke inlet 12 It sets.Various temperature sensor may be used in temperature measuring equipment, and in the present embodiment, temperature measuring equipment is by thermocouple 13, survey It measures instrument and connects thermocouple 13 and the compensating wire composition of measuring instrumentss, wherein thermocouple 13 is fixed at pipe main body 11 On.
