Description
Technical Field
The utility model relates to a technical field is measured to the flue gas, specifically is a redundant pipeline structure of flue gas sample.
Background
In pulverized coal fired boiler, because flue gas temperature is higher and the dust content is great in boiler furnace and the flue, certain deposition can exist in the long-pending month in boiler furnace and flue pressure flow sample pipeline, and the sample pipeline is generally longer moreover, and the deashing operation is more difficult, and the existence of deposition can produce certain influence to the measuring result, and the acid gas in the flue gas also can lead to the fact the corruption to the sample pipeline simultaneously.
Disclosure of Invention
In order to solve the ash removal operation difficulty behind the current sample pipeline deposition, the pipeline corrodes the problem that reduces life easily, the utility model provides a redundant pipeline structure of flue gas sample, it can conveniently realize the ash removal operation, slows down the corruption of flue gas to the sample pipeline, increase of service life.
The technical scheme is as follows: the utility model provides a redundant pipeline structure of flue gas sample, its includes sampler and sampling tube, a serial communication port, the sampling tube includes two, the first interface of first three way solenoid valve is connected through first straight-through joint to the sampler, two are connected respectively to first three way solenoid valve's second interface and third interface sampling tube one end, second three way solenoid valve's second interface and third interface are connected to the other end, second three way solenoid valve's first interface passes through second straight-through joint pressure changer, install a valve on the sampling tube.
The novel LED lamp is further characterized in that the first straight joint and the second straight joint respectively comprise a first joint pipe and a second joint pipe which are connected into a whole through threads, one end of the first joint pipe is a polished rod section, the other end of the first joint pipe is provided with an internal threaded hole, one end of the second joint pipe is a polished rod section, and the other end of the second joint pipe is an external thread matched with the internal threaded hole.
After the utility model is adopted, the two pipelines are mutually switched to sample the smoke gas, so that the corrosion of the smoke gas to the sampling pipeline is slowed down, and the service life of the sampling pipeline is prolonged; when the installation or the dismantlement, only need rotate can accomplish, convenient to use has further increased the practicality.

Detailed Description
Referring to fig. 1 and fig. 2, a redundant pipeline structure for flue gas sampling comprises a sampler 1 and two sampling pipes 2 and 3, wherein the sampler 1 is connected with a first interface 4-1 of a first three-way electromagnetic valve 4 through a first straight joint 12, a second interface 4-2 and a third interface 4-3 of the first three-way electromagnetic valve 4 are respectively connected with one ends of the two sampling pipes 2 and 3 through the first straight joint 12, the other ends of the two sampling pipes 2 and 3 are connected with a second interface 6-2 and a third interface 6-3 of a second three-way electromagnetic valve 6 through a second straight joint 5, the first interface 6-1 of the second three-way electromagnetic valve 6 is connected with a pressure transmitter 7 through the second straight joint 5, and primary valves 8 are mounted on the sampling pipes 2 and 3.
The first straight joint 1 and the second straight joint 5 are identical in structure and respectively comprise a first joint pipe 9 and a second joint pipe 10 which are connected into a whole through threads, one end of the first joint pipe 9 is a polished rod section, the other end of the first joint pipe is provided with an internal threaded hole, one end of the second joint pipe 10 is a polished rod section, and the other end of the second joint pipe is an external thread matched with the internal threaded hole.
Generally, two solenoid valve coils are electrified, a first interface 4-1 of a first three-way solenoid valve 4 is communicated with a second interface 4-2, a third interface 4-3 is closed, a first interface 6-1 of a second three-way solenoid valve 6 is communicated with the second interface 6-2, the third interface 6-3 is closed, and at the moment, the first three-way solenoid valve 4 and the second three-way solenoid valve 6 are communicated with one sampling pipeline 2; when the sampling pipeline 2 needs to be disassembled, firstly, the electromagnetic valve coil is powered off, at the moment, the first interface 4-1 of the first three-way electromagnetic valve 4 is communicated with the third interface 4-3, the second interface 4-2 is closed, the first interface 6-1 of the second three-way electromagnetic valve 6 is communicated with the third interface 6-3, the second interface 6-2 is closed, the first three-way electromagnetic valve 4 and the second three-way electromagnetic valve 6 are communicated with the other sampling pipeline 3, then, the dust deposition sampling pipeline and the corresponding first straight-through connector 1 and the second straight-through connector 5 are disassembled, and the dust deposition sampling pipeline is disassembled to be checked and subjected to dust cleaning treatment. In the figure, 11 is a flue or a hearth.
