in the figure: separator 1, mounting panel 2, sampling tube 3, sample connection 4, blast pipe 5, V-arrangement tee bend 6, sample bottle 7, gasbag 8, pivot 9, cut-off valve plate 10, bar iron 101, stir piece 11, magnet 12.
Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
as shown in fig. 1 and fig. 2, a coal-fired power plant boiler flue gas fly ash sampling device comprises a separator 1 and a mounting plate 2 arranged at the side part thereof, a sampling tube 3 and an exhaust pipe 5 are fixed on the mounting plate 2 from bottom to top, a sampling port 4 is arranged on the sampling tube 3, one end of the sampling port is communicated and fixed with the side part of the separator 1, the exhaust pipe 5 is communicated and fixed with the top part of the separator 1, the bottom of the separator 1 is provided with a V-shaped three-way pipe 6, the top of the V-shaped three-way pipe 6 is fixedly connected with the outlet at the bottom of the separator 1, sampling bottles 7 are respectively fixed on the two side pipes of the V-shaped three-way pipe 6 in a screw connection mode, a cutting valve plate 10 for switching channels is arranged inside the joint of the two side pipes of the V-shaped three-way pipe 6, the bottom of the cutting valve plate 10 is rotatably connected with the inner wall of the V-shaped three-way pipe 6 through a rotating shaft 9, and the middle sections of the upper parts of the two side pipes of the V-shaped three-way pipe 6 are provided with air bags 8.
The rotating shaft 9 and the cut-off valve plate 10 are integrally made of rubber, and one end of the rotating shaft 9 extends to the outside of the V-shaped three-way pipe 6 and is fixed with the poking block 11.
The working principle is as follows: when the utility model is used, the fly ash in the boiler flue enters the separator 1 from the sampling port 4 through the sampling tube 3, the fly ash falls along the inner wall of the separator 1 and presses the channel opened by the V-shaped three-way tube 6 to enter one of the sampling bottles 7, and the gas is discharged into the flue along the exhaust pipe 5 at the top of the separator 1;
when the flying ash in the sampling bottle 7 reaches a certain amount, the poking block 11 is poked to drive the cutting valve plate 10 to rotate through the rotating shaft 9 to rotate from the side pipe channel of the V-shaped three-way pipe 6 which has been sampled to the other side pipe channel, so that the switching of the sampling channel is realized, the magnets 12 arranged above the two side pipes of the V-shaped three-way pipe 6 can fix the cutting valve plate 10 through the strip-shaped iron blocks 101 at the upper end of the cutting valve plate 10, the cutting valve plate 10 is prevented from loosening, and the rotating shaft 9 and the cutting valve plate 10 are arranged into rubber so as to ensure the sealing performance on the flying ash;
after the switching channel of the cutting valve plate 10, the fly ash in the separator 1 can enter another spare sampling bottle 7 for sampling and collection, so that seamless connection of sampling can be realized to ensure sampling stability, meanwhile, the V-shaped three-way pipe 6 is held to close the air bag 8 above the side pipe channel, the fly ash remaining in the closed side pipe channel is blown to fall into the sampling bottle 7 of a collection number, the collected sampling bottle 7 is screwed out from the V-shaped three-way pipe 6 for taking back for assay and analysis after a period of time, thus, the whole sampling is realized, no ash leakage is generated in the sampling process, and the surrounding environment is well protected.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
