The embodiments of this utility model are described below with reference to the accompanying drawings.
[0016] like Figure 1-3 As shown, a waste gas collection and detection device includes a detection component and a collection component 3. The detection component includes a collection container 1 with an inner cavity. One side of the collection container 1 is connected to the collection component 3 through a first connecting pipe 4, and the other side of the collection container 1 is connected to a second connecting pipe 6. A suction fan 8 is provided on the second connecting pipe 6. The collection component 3 includes a funnel-shaped head 12 connected to the end of the first connecting pipe 4. A connector 9 is fitted on the funnel-shaped head 12. The connector 9 includes an inner connecting hole 16. An internal thread 11 is provided on the inner connecting hole 16. A lower protrusion 10 is provided at the end of the inner connecting hole 16 near the collection container 1. An upper protrusion 13 is provided at the end of the funnel-shaped head 12 to block the lower protrusion 10.
[0017] Specifically, when collecting and testing the exhaust gas, the collection component 3 is connected to the exhaust pipe of the exhaust gas to be collected. After connection, the suction fan 8 is started to exhaust the air inside the collection container 1. After the original air inside the collection container 1 is exhausted and filled with the exhaust gas to be collected, the first valve 5 and the second valve 7 are closed to complete the collection of exhaust gas. The collected exhaust gas has high purity and is not mixed with other gases.
[0018] When the collecting component 3 is connected to the exhaust pipe, the outlet of the exhaust pipe is provided with an external thread section, allowing the internal thread 11 to engage with the external thread section. The connector 9 is then tightened to connect with the exhaust pipe. After the connector 9 is tightened, the end of the exhaust pipe is tightly fitted with the sealing plate 14, and the upper protrusion 13 and the lower protrusion 10 are also tightly fitted to maintain a seal and prevent external gas from entering the interior and mixing with the exhaust gas to be collected and detected.
[0019] In some embodiments, a sealing plate 14 is provided in the inner connecting hole 16, and a sealing plate through hole 15 is provided on the sealing plate 14. Specifically, the sealing plate 14 plays a sealing role, and the sealing plate through hole 15 is used for the passage of exhaust gas. The sealing plate 14 can be a rubber plate, which can be bonded to the upper protrusion 13 with glue. After it is fitted with the inner hole sidewall 20, sealant can be applied around the area where it fits with the inner hole sidewall 20.
[0020] In some embodiments, the inner connecting hole 16 includes an inner hole sidewall 20, which is located between the lower protrusion 10 and the internal thread 11. The outer sidewall of the sealing plate 14 engages with the inner hole sidewall 20, and one side of the sealing plate 14 is aligned with the sidewall of the lower protrusion 10.
[0021] Specifically, an inner hole sidewall 20 is provided to allow the upper protrusion 13 and the outer ring of the sealing plate 14 to mate. It is located between the lower protrusion 10 and the internal thread 11. After being set, it facilitates the end of the exhaust pipe to mate with the internal thread 11 to press the sealing plate 14.
[0022] In some embodiments, a first valve 5 is provided on the first connecting pipe 4, and a second valve 7 is provided on the second connecting pipe 6.
[0023] Specifically, by setting the first valve 5 and the second valve 7, it is convenient to close the first valve 5 and the second valve 7 after the waste gas is collected inside the collection container 1, so as to avoid the waste gas collected inside from mixing with the outside air.
[0024] In some embodiments, a display screen 2 is provided on the outer wall of the collection container 1, and a first detector 17, a second detector 18, and a third detector 19 are provided inside the collection container 1.
[0025] Specifically, the display screen 2 can be used to display gas detection data. The internal first detector 17, second detector 18, and third detector 19 are used to detect exhaust gas. The first detector 17, second detector 18, and third detector 19 can be set according to needs. For example, the first detector 17, second detector 18, and third detector 19 can be respectively a carbon monoxide detector, a sulfur dioxide detector, and a carbon dioxide detector.
[0026] By setting up the collection component 3, this application can better connect with the exhaust pipe, ensure the purity of the waste gas to be collected during the waste gas sampling process, avoid the waste gas to be tested from mixing with air, and better collect and detect the waste gas.
