Below in conjunction with the accompanying drawings matrix form mixing isokinetic sampling's device of the present invention is described further.
Accompanying drawing explanation
Fig. 1 is the structural representation of matrix form of the present invention mixing isokinetic sampling's device.
Detailed description of the invention
As it is shown in figure 1, matrix form of the present invention mixing isokinetic sampling's device includes analytic unit 1 and sampling unit 3, sampling unit 3 Including overlapping constant speed circulating sampling device more.Constant speed circulating sampling device includes that sampling gun, sampling gun include the body of a gun and sampling tube 10, The 316L stainless steel tube that wherein sampling tube 10 uses a diameter of 25mm thickness to be 2mm, the mouth of pipe of sampling tube 10 is positioned at flue 11 is internal, is provided with pitot tube speed measuring device (being not drawn in figure) outside sampling tube 10.The mouth of pipe of multiple sampling tubes 10 is at cigarette Surrounding in the internal same cross section in road 11 is uniformly distributed, and the mouth of pipe is towards direction of the wind comes from.According to " in Concentration in Fixed Pollutants Source admittedly Body particulate matter measures and the gaseous contaminant method of sampling " requirement of (GB/T16157-1996) 4.2.4.2, divides flue 11 section Becoming suitable homalographic fritter, Ge Kuai center is measuring point.Flue 11 cross section is divided into four squares of homalographic by the present embodiment Shape, the mouth of pipe of four sampling tubes 10 lays respectively at the center of four rectangles, so makes sampling have more objectivity and representativeness.Rifle Body is positioned at outside flue 11, and the body of a gun connects sampling conduit 7, sampling conduit 7 outer wall is provided with heater and is dried dress Putting, in keeping sampling conduit 7, flue-gas temperature is not less than 180 DEG C.Sampling blower fan 4 is installed, blower fan 4 of sampling on sampling conduit 7 On be provided with converter, converter can change the rotating speed of sampling blower fan 4, respectively pacifies at the sampling air inlet of blower fan 4 and gas outlet Equipped with a sampling electromagnetic valve 5.The other end of sampling conduit 7 is connected with the inlet union of blender 2, the import of blender 2 Tube wall below joint is long funnel-form, and the lower end of long funnel-form pipe is provided with automatic ash removing rod 16, and automatic ash removing rod 16 is permissible Around the axis of rotation being fixed on blender 2 inwall.Being VERTICAL TUBE 14 below long funnel-form pipe, the caliber of VERTICAL TUBE 14 is with each The caliber sum of sampling tube 10 is identical, and in so can ensure that blender 2, flue gas flow rate is close to the mean flow rate of flue 11, carries The objectivity of high double sampling and representativeness.The length of VERTICAL TUBE 14, more than the length of ten sampling pipes 10, so can make to adopt Sample gas body is flow speed stability in VERTICAL TUBE 14, it is simple to carry out double sampling.VERTICAL TUBE 14 bottom is provided with double sampling pipeline 15, It is internal that VERTICAL TUBE 14 is stretched in double sampling pipeline 15 one end, and the other end is connected with the air inlet of analytic unit 1, the second sampling tube Distance between 10 and VERTICAL TUBE 14 upper end is the length of ten sampling pipes 10.In the gas outlet of analytic unit 1 and flue 11 Portion is connected by exhaustor 12, is connected and has threeway 13 between the gas outlet of analytic unit 1 with exhaustor 12, and threeway 13 is also It is connected with the bottom of VERTICAL TUBE 14.It is easy to the gas after analysis being completed be discharged downstream in flue 11.
It is provided with blowback between sampling electromagnetic valve 5 and the sampling gun matched at sampling blower fan 4 air inlet and sweeps pipeline 9, blowback Sweeping and be provided with blowback electromagnetic valve 6 on pipeline 9, the connection of pipeline 9 other end is swept in blowback back-blowing device 8.Purging pressure can be according to cigarette The instant pressure in this cross section in road 11, slightly above this pressure purges, and reduces the interference to neighbouring sample operating point.Source purge gas Station-service compressed air can be used to use after entering surge tank after pressure regulation, it is ensured that pressure stability.
The duty of sampling electromagnetic valve 5 and blowback electromagnetic valve 6 is controlled switching, sampling electromagnetic valve 5 and blowback electromagnetism by PLC The switching action time of valve 6 is respectively less than 1s, and its valve body is all sampled Stainless steel 316 L.
The material of above-mentioned all pipelines all uses Stainless steel 316 L.
The operation principle of matrix form of the present invention mixing isokinetic sampling's device is as follows: when normally working, and four set isokinetic sampling's devices are respectively Sample in the way of constant speed tracking, i.e. record the flow velocity of gas in flue 11 by pitot tube speed measuring device, by flow speed data Feeding back in the converter arranged on sampling blower fan 4, converter adjusts the rotating speed of sampling blower fan 4, makes sample gas at sampling tube Flow velocity in road 7 is the most identical with flue 11.Sample gas carries out secondary current-sharing in entering blender 2 afterwards, and by two Secondary sampling conduit 15 obtains final sample gas, is sent to analytic unit 1.
When certain sampling gun breaks down, such as situations such as sampling blower fan 4 tripping operations, can pass through to close sampling blower fan 4 air inlet/outlet The sampling electrodynamic valve of mouth will appear from the sampling blower fan 4 of fault isolates, after the signal that is concurrently out of order carries out online Fast-Maintenance and maintenance Put into operation again.User can carry out branch reverse blow work by default, it is ensured that sampling tube according to practical situation every day Road 7 is totally, dust stratification and the steady in a long-term of system do not run.
Embodiment described above is only to be described the preferred embodiment of the present invention, not carries out the scope of the present invention Limiting, on the premise of designing spirit without departing from the present invention, technical scheme is made by those of ordinary skill in the art Various deformation and improvement, all should fall in the protection domain that claims of the present invention determines.
