Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, a kind of stationary source particle monitoring instrument clean air blowing mechanism provided by the invention is described in detail.
Figure 1A and 1B is shown respectively front view and the sectional view thereof of a kind of clean air blowing mechanism for stationary source particle monitoring instrument. Fig. 2 illustrates that this blowing mechanism is installed to the schematic diagram on monitor. As shown in Figure 1A to Fig. 2, this stationary source particle monitoring instrument clean air blowing mechanism includes, pedestal 10, from the outward extending pipe group welding piece 1 in the side of pedestal 10 be arranged on the blower weldment 2 outside pipe group welding piece 1, air-flow is blown into from blower weldment 2, then flow through pipe group welding piece 1, and owing to the special construction of pipe group welding piece 1 makes the uniformly quickly flowing in tube chamber of air-flow, thus effectively stoping the pollution of the flue dust glass lens 3 to being arranged on pedestal 10 opposite side. Here, pedestal 10 is hollow, and is connected with pipe group welding piece 1.
Specifically, pipe group welding piece 1 can be made up of interior pipe group welding piece 11, outer tube group welding piece 12, guide duct 13 and induced duct 14. Wherein, guide duct 13 is fastened on the side of pedestal 10 and is connected with pedestal 10; It is outside that interior pipe group welding piece 11 is fastened on guide duct 13, and induced duct 14 is set in the length length less than interior pipe group welding piece 11 of interior pipe group welding piece 11 outside and induced duct, and induced duct 14 is connected with guide duct 13; It is outside and be connected with interior pipe group welding piece 11 and induced duct 14 respectively that outer tube group welding piece 12 is set in induced duct 14, and outer tube group welding piece 12 length is set more than the length of induced duct 14 and less than the length of interior pipe group welding piece 11. Interior pipe group welding piece 11, outer tube group welding piece 12, guide duct 13 and induced duct 14 are all hollow circular cylinder and coaxial line (as shown in Figure 1B) is arranged.
By above-mentioned set-up mode so that three layers tube chamber can be defined between air inlet and gas outlet. Here, owing to the nozzle diameter of outer tube group welding piece 12, induced duct 14, interior pipe group welding piece 11 and guide duct 13 is for successively decrease successively, hence into air-flow can not be passed directly to gas outlet, but constantly spread to surrounding so that air-flow is more uniform at circumferencial direction. And the diameter of outer tube group welding piece 12, induced duct 14, interior pipe group welding piece 11 successively decrease so that the movement velocity of air-flow is accelerated gradually so that the wind speed of air outlet improves, and effectively stops the flue dust pollution to glass lens 3.
It addition, for the air-tightness of reinforced pipe assembly, it is possible to sealing gasket 5 is set between guide duct 13 and pedestal 10.
Blower weldment 2 can include gas-tpe fitting 21 and sealing ring 22, and wherein, gas-tpe fitting 21 is for hollow circular cylinder and is arranged on outer tube group welding piece 12, and is connected with outer tube group welding piece 12. Sealing ring 22 is arranged between gas-tpe fitting and outer tube group welding piece, for strengthening the air-tightness of blower weldment 2. Further, gas-tpe fitting 21 is from the horizontal by 45 degree of angles.
Additionally, as shown in Figure 4, air-flow enters the position, side of second layer tube chamber (induced duct 14) inwall and is provided with step site a, and this is step site has flow-disturbing effect.
Guide duct 13 nozzle diameter cut-off rule is just to gas-tpe fitting 21, and the pipe height of its nozzle diameter cut-off rule left part is in charge of height in right side.
Fig. 3 illustrates the air flow direction figure of clean air blowing mechanism. As it is shown on figure 3, clean air from the cleaning air entrance tube chamber that gas-tpe fitting 21 enters, after bumping against the inner tubal wall of outer tube group welding piece 12, it is divided into two strands of air-flows. One enters from upper right side, and velocity attitude is tilted to the left gradually; Another stock enters from lower left, and velocity attitude is tilted to the right gradually. Owing to induced duct 14 is provided with the stage portion with flow-disturbing effect, (the nozzle diameter cut-off rule of induced duct 14 is just to gas-tpe fitting 21, the pipe height of its nozzle diameter cut-off rule left part is in charge of height in right side, thus producing stage portion), left part air-flow is little through this stage portion resistance, and therefore air velocity is big; And right part air-flow resistance when this is step site is big, therefore air velocity is little. After two strands of air-flows enter, owing to there is speed difference, the air velocity of left part is more than the air velocity of right part, so that while intraluminal air-flow flows in the vertical direction, flow slightly in the clockwise direction, producing the rotary wind of flowing, this rotation wind energy provides stable, uniform purging air to him.
Additionally, due to clean air directly can not lead to gas outlet from air inlet, but constantly spread to surrounding so that air-flow is more uniform at circumferencial direction. And the nozzle diameter of outer tube group welding piece 12, induced duct 14, interior pipe group welding piece 11 and guide duct 13 is successively decrease so that the movement velocity of air-flow is accelerated successively, the wind speed making air outlet improves, as shown in Figure 3, effectively stop the flue dust pollution to glass lens 3, and through glass lens 3 mouthfuls blowing evenly so that clean cleaner.
Additionally, owing to glass lens 3 to be purged is arranged on the opposite side of pedestal 10, therefore, purging air is not in contact with glass window, so glass window will not be polluted by moisture and pollutant in purging air, and simply play and intercept the effect that outside flue dust enters.
Finally it should be noted that, above example is only in order to describe technical scheme rather than this technical method is limited, the present invention can extend to other amendment, change, application and embodiment in application, and it is taken as that all such amendments, change, application, embodiment are all within the scope of the spirit or teaching of the present invention.
