Description

Technical Field

[0001] This utility model relates to the field of waste gas concentration detection technology, and in particular to a waste gas concentration detection device. Background Technology

[0002] Waste gas concentration detection is a core component in ensuring the effectiveness of pollution control and safe production. By monitoring the concentration of pollutants such as hydrogen sulfide and ammonia in waste gas in real time, data support is provided for the control of treatment processes.

[0003] Existing exhaust gas concentration detection devices suffer from several drawbacks. Fine particles in the exhaust gas adhere to the device, reducing detection accuracy and significantly shortening its lifespan. Furthermore, they lack the speed and convenience for quickly and easily sampling the exhaust gas when sampling is required. To overcome these disadvantages, this invention provides an exhaust gas concentration detection device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waste gas concentration detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a waste gas concentration detection device, comprising a conveying pipe, an air inlet and an air outlet, a first air pipe fixedly connected to the air inlet, one end of the first air pipe fixedly connected to the air outlet, a detection component disposed on the first air pipe, a filter chamber fixedly connected to the first air pipe and located on one side of the detection component, a particle filter component disposed on the filter chamber, a second air pipe fixedly connected to the first air pipe, an internal spiral thread disposed at one end of the second air pipe, a collection cylinder disposed above the second air pipe, a connecting component disposed on the collection cylinder, a second valve fixedly connected to the collection cylinder, second handles fixedly connected to both sides of the collection cylinder, and a flow guiding component disposed on the first air pipe.

[0006] Furthermore, the detection assembly includes a detection device fixedly connected to the first trachea, and a control panel is fixedly connected to one side of the detection device.

[0007] Furthermore, the particle filtration assembly includes several slots formed at the top of the filtration chamber, a filter plate is slidably connected to the slots, and a first handle is fixedly connected to the top of the filter plate.

[0008] Furthermore, the connecting assembly includes a tension thread formed at the air inlet end of the collecting cylinder, which engages with an internal thread at one end of the second air pipe to thread-connect the collecting cylinder and one end of the second air pipe.

[0009] Furthermore, a sealing block is fixedly connected to the air inlet end of the collecting cylinder, and a sealing ring is fixedly connected to one end of the second air pipe, with the sealing ring located inside the sealing block.

[0010] Furthermore, the drainage assembly includes a one-way solenoid valve fixedly connected to the first air pipe and located above the air outlet, and a first valve fixedly connected to the first air pipe and located above the air inlet.

[0011] The beneficial effects of this utility model are:

[0012] In use, this invention filters out fine particles in the exhaust gas through a particle filter assembly before recording and detecting the concentration. This prevents these fine particles from adsorbing onto the detection device, which would reduce the accuracy of the concentration detection and damage the device, thus shortening its lifespan. The exhaust gas is then sampled and collected through a collection cylinder for more detailed detection. Attached Figure Description

[0023] As shown in the figure, the connecting assembly includes a tension thread 17 on the air inlet end of the collecting cylinder 16. The tension thread 17 engages with the internal thread 15 at one end of the second air pipe 13, thereby threading the collecting cylinder 16 and one end of the second air pipe 13 together, for connecting the collecting cylinder 16 and the second air pipe 13.

[0024] As shown in the figure, a sealing block 18 is fixedly connected to the air inlet end of the collection cylinder 16, and a sealing ring 14 is fixedly connected to one end of the second air pipe 13. The sealing ring 14 is located inside the sealing block 18 and is used to seal the connection between the collection cylinder 16 and the second air pipe 13 to prevent exhaust gas from overflowing.

[0026] Working principle: In use, first check whether the entire device is intact. After the check is completed, use the second handle 20 to position the collection cylinder 16 above the second air pipe 13, and then use the tension thread 17 and the internal thread 15 to fix the collection cylinder 16 on the second air pipe 13. Then, use the first handle 12 to insert the filter plate 11 into the slot 10 on the filter chamber 9. Then, open the first valve 6 and the one-way solenoid valve 5. Then, the exhaust gas enters the first air pipe 4 from the air inlet 2, and then enters the filter chamber 9. After passing through the filter plate 11, the fine particles in the exhaust gas are filtered out. After filtration, it enters the detection device 7 to detect the concentration of the exhaust gas. After the detection is completed, the data of the exhaust gas concentration is displayed on the control panel 8. When it is necessary to sample the exhaust gas, open the second valve 19 to allow the exhaust gas to enter the collection cylinder 16 for collection. After collection is completed, close the second valve 19.
