Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heating furnaces, in particular to a sampling device for detecting tail gas from a heating furnace. Background Art
[0002] When the heating furnace is in use, exhaust gas will be generated after the fuel is burned. For the purpose of environmental protection, the exhaust gas of the heating furnace will be sampled for detection. If the exhaust gas discharged by the heating furnace does not meet the emission standards of the "Petrochemical Industry Pollutant Emission Standard" (GB131571-2015), it is necessary to use technology to transform the heating furnace until the exhaust gas discharged by the heating furnace meets the emission standards of the "Petrochemical Industry Pollutant Emission Standard" (GB131571-2015). In this process, it is necessary to insert a sampling tube into the exhaust pipe of the heating furnace to sample the exhaust gas. In actual operation, when the sampling tube is sampling, the exhaust pipe of the heating furnace at the sampling location is in an open state, and the sampling location of the exhaust pipe of the heating furnace will overflow gas. Although the staff is outdoors, the outdoor environment will dilute the gas overflowing from the sampling location of the exhaust pipe of the heating furnace, but it will still make the staff in an unsafe environment for a long time when sampling, which is not conducive to the health of the staff. Therefore, a sampling device for exhaust gas detection of the heating furnace is needed to meet the demand. Utility Model Content

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0017] Example 1
[0018] Reference Figure 1-4 , a sampling device for detecting exhaust gas from a heating furnace, comprising a square cylinder 1, the square cylinder 1 is fixed on the exhaust pipe of the heating furnace, a fixing sleeve 2 is fixed on the square cylinder 1, a plurality of threaded holes 3 are equidistantly and penetrated on the fixing sleeve 2, wherein first bolts 6 are installed in two threaded holes 3, and clamping plates 4 are penetrated on the two first bolts 6, and two first grooves 7 are symmetrically arranged on the opposite sides of the two clamping plates 4. By using the cooperation of the two first bolts 6 and the two threaded holes 3, not only the two clamping plates 4 are limited on the fixing sleeve 2, but also the positions of the two clamping plates 4 are limited to a fixed position. At the same time, the two first grooves 7 on the two clamping plates 4 jointly form a circle for the sampling tube to pass through, first sealing gaskets 5 are fixed on the opposite sides of the two clamping plates 4 and the square cylinder 1, and the two first sealing gaskets 5 are provided with second grooves 8 corresponding to the first grooves 7. When the first sealing gasket 5 is used, the first sealing gasket 5 is tightly attached to the square cylinder 1, so that no exhaust gas from the heating furnace will be discharged from the square cylinder 1, and the two first grooves 7 and the two second grooves 8 jointly clamp the sampling tube.
[0019] Working principle: When in use, the two first grooves 7 and the two second grooves 8 provide reserved space for the two clamping plates 4 to clamp the sampling tube. After the two clamping plates 4 clamp the sampling tube, the two first bolts 6 and the two threaded holes 3 on the fixing sleeve 2 are used to fix the sampling tube in the square tube 1 and the exhaust pipe of the heating furnace. During the sampling process, not only will there be no gas overflow at the sampling point of the exhaust pipe of the heating furnace, but the staff will not need to hold the sampling tube all the time, which reduces labor intensity and is safe.
[0020] Example 2
[0021] In Example 1, after sampling at the sampling point of the exhaust pipe of the heating furnace is completed, the square tube 1 has no sealing mechanism, and the exhaust gas in the exhaust pipe of the heating furnace cannot be completely discharged to the designated position. Figure 1-3 As another preferred embodiment of the utility model, the difference from Embodiment 1 is that a blocking mechanism is fixed on the exhaust pipe of the heating furnace above the square cylinder 1. After the sampling is completed, the blocking mechanism is used to block the square cylinder 1 so that the exhaust gas in the exhaust pipe of the heating furnace can be discharged to the designated position.
[0022] The blocking mechanism includes a baffle 12, through which a plurality of second bolts 14 are penetrated, and the plurality of second bolts 14 respectively correspond to the plurality of threaded holes 3. A second sealing gasket 13 is fixed on the baffle 12 between the plurality of second bolts 14. By utilizing the mutual cooperation between the exhaust pipe of the heating furnace and the plurality of threaded holes 3, the baffle 12 with the second sealing gasket 13 can be tightly attached to the square tube 1, thereby blocking the square tube 1.
[0023] An adjusting mechanism is fixed on the baffle 12, and the adjusting mechanism includes a fixing plate 11, on which a plug-in rod 10 is fixed, and on which a cylinder 9 is mounted. The length of the plug-in rod 10 inserted in the cylinder 9 can not only be adjusted, but the plug-in rod 10 can also rotate in the cylinder 9. The cylinder 9 is fixed on the exhaust pipe of the heating furnace above the square cylinder 1. When sampling, the baffle 12 is rotated to the top of the square cylinder 1 so that the square cylinder 1 will not affect the sampling of the exhaust gas.
[0024] Working principle: After the sampling is completed, unscrew the two first bolts 6, let the two clamping plates 4 with the two first sealing gaskets 5 detach from the square cylinder 1, and then move the baffle 12, the baffle 12 drives the insertion rod 10 to rotate in the cylinder 9, and then let the insertion rod 10 continue to be inserted into the cylinder 9, let the baffle 12 with the second sealing gasket 13 against the square cylinder 1, and then install multiple second bolts 14 in multiple threaded holes 3 respectively, with the help of the second sealing gasket 13, let the baffle 12 completely seal the square cylinder 1, so that the exhaust gas in the exhaust pipe of the heating furnace can be discharged to the designated position.
[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
