Description

Technical Field

[0001] The invention relates to the technical field of tar detection, in particular to a device for detecting the tar content of tail gas used for pyrolysis treatment. Background Art

[0002] During the preparation of activated carbon, the carbonization furnace exhaust contains a large amount of combustible gas. If it is directly discharged, it will not only cause air pollution, but also cause waste of combustible gas. The usual practice is to introduce these combustible carbonization exhaust gases into the incinerator for combustion to utilize the heat energy generated by combustion, consume the combustible gas therein, and then discharge the exhaust gas. The combustible components contained in the carbonization exhaust gas mainly include tar and coal powder, which are gasified at about 300°C. At the same time, it is also necessary to sample and test the tar in the exhaust gas.

[0003] In the prior art, sampling is usually performed at the mouth of the exhaust pipe or the sampling tube is inserted into the exhaust pipe, but this increases the difficulty of operation for the staff, and the sampling tube is also easy to touch the inner wall of the exhaust pipe. Alternatively, the exhaust sampling device is installed on the exhaust pipe in the prior art, and the exhaust gas sampling work can be conveniently and quickly performed by replacing the sampling device. For example, in the patent with publication number CN208308521U, a row of sampling tubes distributed vertically are connected to the side wall of the connecting pipe, and each sampling tube is installed with a switch valve, which facilitates the test personnel to sample and analyze the biogas at any time. However, there is a distance between the exhaust sampling device on the exhaust pipe and the exhaust pipe, and the tar in the exhaust gas will condense into a viscous liquid when it encounters a lower temperature when discharged from the exhaust pipe. Therefore, part of the tar in the exhaust gas will condense before entering the sampling tube, thereby affecting the subsequent tar detection. Summary of the invention

[0046] One end of the threaded rod 74 located in the fixed ring 72 can squeeze the sliding ring 724 through the second inclined surface 719, thereby moving the sliding ring 724 and the lifting ring 75 up and down.

[0047] When the connecting ring 711 rotates with the lifting ring 75 , the lifting frame 715 is located in front of the blocking rod 713 .

[0048] Specifically, while the exhaust mechanism 8 is working, after collecting the gas, the oil flushing mechanism 7 can automatically spray the inside of the conduit three 71 and the cover 610, and the sprayed gas is a gas without tar on the outside, which prevents the tar from condensing again during subsequent spraying, and also discharges a small amount of condensed tar into the collection pipe 61, thereby improving the subsequent detection accuracy.

[0049] In another embodiment provided by the present invention, the exhaust mechanism 8 includes a fixed block 81 fixedly connected to the bottom end of the connecting ring 711, a rotating block 82 is provided on one side of the fixed block 81, and the rotating block 82 is fixed in the fixed ring 72, an air guide port 84 is opened at the bottom end of the fixed ring 72, and an insert ring 83 is fixedly connected to the bottom end of the lifting ring 75, and the insert ring 83 can be movably inserted in the air guide port 84.

[0050] The push plate 723 and the fixed plate 727 are located at two opposite sides of the rotating block 82 and the guide groove 1 712 . The fixed block 81 and the rotating block 82 are arranged at the same side of the rotating block 82 , and the fixed block 81 is higher than the rotating block 82 .

[0051] Specifically, and through the adjustment of the threaded rod 74, the oil flushing mechanism 7 can spray gas into the second conduit 69, so that the tar in the cavity 68 is sprayed into the incinerator 1 through the first conduit 62 to burn it.

[0052] Working principle: During operation, the exhaust gas in the exhaust pipe 3 will be extracted through the exhaust device. When sampling and testing is required, the upper threaded rod 74 is first rotated to move the upper threaded rod 74 into the fixed ring 72, and then the sliding ring 724 moves downward. The guide groove 2 718 and the guide groove 3 728 on the lower side are connected. The sliding ring 724 drives the link 711 and the lifting ring 75 to move downward, so the insert ring 83 will move downward into the air guide port 84, so that the inner cavity of the fixed ring 72 is separated from the inner cavity of the exhaust pipe 3, so that the gas between the bottom end of the lifting ring 75 and the fixed ring 72 is kept quantitative, and at the same time, the connecting block 78 at the bottom end of the lifting ring 75 moves downward. When the exhaust gas in the exhaust pipe 3 When the turbofan 4 is driven to rotate, the turbofan 4 will drive the rotating ring 73 to rotate. When the connecting block 78 on the fixed ring 72 conflicts with the connecting block 78 on the lifting ring 75, the lifting ring 75 will be driven to rotate, and then the lifting ring 75 drives the fixed block 81 to rotate nearly one circle. Finally, the fixed block 81 meets and stops with the rotating block 82, so that a certain amount of gas between the bottom end of the lifting ring 75 and the fixed ring 72 is discharged into the lower guide groove 2 718, and then the gas is introduced into the collecting pipe 61 through the conduit 3 71, and the lifting plate 63 is automatically moved downward to make room for the gas. After the gas is discharged from the collecting pipe 61, the lifting plate 63 will automatically move upward to prevent other gas from entering.

[0053] When the chain 711 rotates to the upper end of the lifting frame 715 and conflicts with the push plate 723, the lifting frame 715 will drive the push plate 723 to rotate a certain distance. Then, when the inclined surface 1 716 conflicts with the extrusion block 729, the blocking rod 713 will also conflict with the triangular block 725, and the lifting frame 715 will be pressed downward, so that the lifting frame 715 and the push plate 723 are separated. Under the action of the spring 2 76, the push plate 723 rebounds quickly, and the notch on the blocking rod 713 is connected to the guide groove 1 712, so that the push plate 723 pushes The external gas enters the space surrounded by the fixed block 81 and the rotating block 82, and is discharged from the conduit 3 71. At this time, the fixed block 81 and the rotating block 82 are located on two opposite sides of the guide groove 3 728, and then the fixed block 81 and the rotating block 82 are in conflict with each other. This allows the conduit 3 71 and the inside of the cover 610 to be automatically sprayed after the gas is collected, and the sprayed gas is the gas without tar on the outside, which prevents the tar from condensing again during the subsequent spraying, and discharges a small amount of condensed tar into the collection pipe 61, thereby improving the accuracy of subsequent detection;

[0054] When the collection is completed, the threaded rod 74 is reset. Due to the setting of the torsion spring 710, the lifting ring 75 is reset. After the inspection, the tar needs to be processed. The tar contains energy and can be used for combustion and its heat energy is utilized. After the inspection, the tar is placed in the cavity 68, and then the collection pipe 61 is tightened with the cover 610, and then the lower threaded rod 74 is rotated to move the lower threaded rod 74 into the fixed ring 72, so that the sliding ring 724 moves upward, and then the upper guide groove 2 718 and the upper guide groove 3 728 are connected, and then the connecting block 78 on the upper side of the lifting ring 75 contacts the connecting block 78 on the rotating ring 73 and is driven to rotate, and the gas is sprayed into the conduit 2 69, so that the tar in the cavity 68 is sprayed into the incinerator 1 through the conduit 1 62 to burn it.

[0055] It should be noted that the insertion frame 721 is provided so that when the link 711 moves up and down, the upper end of the link 711 and the fixed ring 72 can be sealed, so that when the push plate 723 rotates, the gas impact force is greater;

[0056] Before the lifting frame 715 is separated from the push plate 723, the push plate 723 will enlarge the space between the push plate 723 and the fixed plate 727, and then the guide port at the other end of the external guide port 9 is located at the upper side between the push plate 723 and the fixed plate 727, so that the gas on the outer wall is sucked into the space between the push plate 723 and the fixed plate 727, and then the lifting frame 715 and the push plate 723 are separated;

[0057] When the threaded rod 74 is rotated, if the threaded rod 74 cannot be screwed to the bottom at once, it means that the lifting ring 75 and the connecting block 78 on the rotating ring 73 are just in conflict. At this time, the threaded rod 74 is rotated back and then rotated inward.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
