Embodiment
As shown in Figure 1, be the centrifugal high-temperature sampling probe system that the utility model discloses, comprise high-temperature sampling probe 1, centrifugal spiral track 2, inertia gas dirt separation vessel 3, inert filter device 4, precision filter 5, aspiration pump 6 and thrower 7.
The import of high-temperature sampling probe 1 connects flue 9, and the outlet of high-temperature sampling probe 1 connects the import of centrifugal spiral track 2, and the outlet of centrifugal spiral track 2 connects inertia gas dirt separation vessel 3.Centrifugal spiral track 2 can be cylindrical helical pipe.
Inertia gas dirt separation vessel 3 is made up of T font pipe 31 and isolated tube 32.Isolated tube 32 is inserted by transverse tube 311 one end of T font pipe 31, and be socketed in the transverse tube 311 of T font pipe 31, the outlet of the outer termination centrifugal spiral track 2 of isolated tube 32, the inner of isolated tube 32 is positioned at transverse tube 311 and vertical tube 312 junction of T font pipe 31, and the inner of isolated tube 32 forms angular cut 321, the back side of angular cut 321 is just to the vertical tube 312 of T font pipe 31.In order to separation gas dirt better, the inner angular cut 321 of isolated tube 32 preferably stretches into transverse tube 311 other end of T font pipe 31 slightly, namely only slight beyond the junction of transverse tube 311 and vertical tube 312.
Transverse tube 311 other end of T font pipe 31 installs thrower 7, and the playpipe 71 be connected with pressurized air is housed in thrower 7, and the outlet 72 of thrower 7 is connected to flue 9.Thrower 7 specifically can be in a tubular form, the sidewall of thrower 7 is formed opening 73 to be connected with transverse tube 311 other end of T font pipe 31, the playpipe 71 be connected with pressurized air stretches into and the opening 73 crossed sidewall and be fixed in thrower 7 from a mouth of pipe 74 of thrower 7, and namely another mouth of pipe of thrower 7 exports 72 and be connected to flue 9.
In the vertical tube 312 of T font pipe 31, inert filter device 4 is installed to be connected with one end of three-way pipe 8 again.In order to separation gas dirt better, the vertical tube 312 of T font pipe 31 is connected by the transverse tube 311 of hemisphere 313 with T font pipe 3, and inert filter device 4 is arranged in hemisphere 313.
The other end of three-way pipe 8 connects anti-purge gas by electromagnetic valve 81, and the 3rd end of three-way pipe 8 installs high-temperature electromagnetic valve 82, precision filter 5 and aspiration pump 6 successively, then is connected to analysis meter.
Be separated to realize gas dirt better, the utility model also comprises constant temperature oven 10, and centrifugal spiral track 2, inertia gas dirt separation vessel 3, inert filter device 4 and thrower 7 are arranged in constant temperature oven 10.Constant temperature oven 10 can provide 200 DEG C of constant temperature, to make in flue gas moisture content can not condensation, use 200 DEG C of high-temperature sampling probes 1 again, sample under reaching high dust concentration and do not block, reduce the absorption of micro-thing and active constituent, avoid the generation of measuring error, improve the degree of accuracy analyzed, make the utility model go for the trace gas analysis of high moisture content concentration, high dust concentration in flue gas.
During utility model works, utilize playpipe 71 in thrower 7 to spray pressurized air and produce negative pressure, flue gas is sucked out from flue 9, again in the direction of arrows, through high-temperature sampling probe 1, centrifugal spiral track 2, inertia gas dirt separation vessel 3, thrower 7, then, mix with pressurized air, then flow back to flue 9.Control the compressed-air actuated pressure of thrower 7, the flow velocity by centrifugal spiral track 2 can be changed, the flue gas of high flow rate produces centrifugal motion in centrifugal spiral track 2, because the quality of dust is far longer than gas, dust can move along the outside tube wall of centrifugal spiral track 2, gas is then in the inner side tube wall motion of centrifugal spiral track 2, and after the centrifugal effect of multi-turn, gas-dirt is fully separated.Subsequently, flue gas sends inertia gas dirt separation vessel 3 to by isolated tube 32, and by the stop of angular cut 321, dust is difficult to vertical tube 312 and the inert filter device 4 that counter motion enters T font pipe 31 under inertia effect, and this has just purified flue gas further.When the negative pressure of aspiration pump 6 is less than the negative pressure of inertia gas dirt separation vessel 3, purifying smoke will be drawn out of, and filters further, be finally transported to analysis meter through precision filter 5.If through the use of a rapid lapse of time, inert filter device 4 has dust accumulation, then can close high-temperature electromagnetic valve 82, opens solenoid valve door 81, with blowback gas washing reverse blow inert filter device 4, regenerates.
These are only specific embodiment of the utility model, the restriction not to protection domain of the present utility model.All equivalent variations done according to the mentality of designing of this case, all fall into the protection domain of this case.
