[0002] Industrial waste gas is a general term for various waste gases generated during fuel combustion and production processes in the factory area of ​​an enterprise. It must be treated and meet the standards before it can be discharged reasonably. Industrial waste gas detection includes organic waste gas detection and inorganic waste gas detection. Among them, inorganic waste gas detection is more common, mainly including sulfur oxides, nitrogen oxides, carbon oxides, halogens and their compounds.

[0003] In the prior art, most industrial waste gas detection uses waste gas detectors for detection. The detector can be installed on the waste gas emission pipeline for real-time monitoring and recording of emission data. At present, the detection probe of the real-time monitoring detector is directly installed on the wall of the waste gas pipeline. In comparison, the size of the detection probe is small, while the size of the waste gas pipeline is large. Since the waste gas is not deliberately mixed when it is discharged after treatment, the different components of waste gas discharged in the waste gas pipeline will be at different distances from the detection probe, resulting in the pollutants in the waste gas close to the detection probe being easier to be captured by the detection probe, while the pollutants in the waste gas far away from the detection probe are more difficult to be captured, resulting in incomplete waste gas detection and low and inaccurate detection content values, affecting the detection results. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides an industrial waste gas detection device, which is used to solve the problem in the prior art that the waste gas detection is incomplete and the detection content value is low and inaccurate due to the different distances between the waste gas of different components discharged from the waste gas pipeline and the detection probe of the detector installed on the pipe wall of the waste gas pipeline.

[0007] Preferably, a sleeve is horizontally fixedly connected to the fixing frame, and an end of the sleeve away from the baffle is movably connected to a support frame supported on a side of the exhaust pipe away from the baffle, and a support spring is arranged between the sleeve and the support frame.

[0008] Preferably, a vertical support rod is fixedly connected to the support frame.

[0009] Preferably, the gas collecting hood is in the shape of a funnel which is small at the top and large at the bottom, and there are multiple gas collecting hoods, and the multiple gas collecting hoods are equidistantly arranged in the vertical direction.

[0010] Preferably, a protective cover is provided on the surface of the portion of the connecting line located in the exhaust gas pipe.

[0011] Preferably, the fan blade is arranged on a side of the bottom of the fixing frame away from the baffle, and the side of the fan blade away from the baffle is inclined upward.

[0012] Preferably, the rotating shaft of the fan blade is rotatably connected to a permanent magnetic low-resistance bearing connection seat at the bottom of the fixing frame.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: an industrial waste gas detection device, comprising a detector 1, a detection probe 2 and a connecting line 3 between the two, and a protective cover 13 is provided on the surface of the connecting line 3 located in the waste gas pipe 5 to prevent the connecting line 3 from being corroded by the waste gas;

[0022] It also includes a fixing frame 4 for installing and fixing the detection probe 2, a sleeve 9 is horizontally fixedly connected to the fixing frame 4, and the end of the sleeve 9 away from the baffle 6 is movably connected to a support frame 10 supported on the side of the exhaust pipe 5 away from the baffle 6, a support spring 11 is provided between the sleeve 9 and the support frame 10, and a vertical support rod 12 is fixedly connected to the support frame 10. The left side of the fixing frame 4 is fixed, and the right side is supported on the inner wall of the exhaust pipe 5 by the support rod 12 to be fixed by support, so as to avoid the right side being suspended in the air and the left side of the exhaust pipe 5 being pulled for a long time, causing deformation and damage to the exhaust pipe 5;

[0023] The fixing frame 4 is installed in the vertical section exhaust pipe 5 for industrial exhaust gas emission. A baffle 6 with a through slot 501 corresponding to the exhaust pipe 5 is fixedly connected to one side of the fixing frame 4. The detection probe 2 is installed in the fixing frame 4 at a position close to the top, and a plurality of detection through holes 201 are arranged on the outer shell of the detection probe 2. The existing detection through holes 201 are only at the end, and the contact channel is too small to be conducive to capturing harmful components in the exhaust gas.

[0024] A gas collecting hood 7 located directly below the detection probe 2 is vertically fixedly connected in the fixing frame 4. The gas collecting hood 7 is in the shape of a funnel with a small top and a large bottom. There are multiple gas collecting hoods 7, and the multiple gas collecting hoods 7 are equidistantly arranged in the vertical direction, and the exhaust gas is continuously collected from all sides to the bottom of the detection probe 2, so that the harmful components in the exhaust gas are more easily captured by the detection probe 2;

[0025] The detection probe 2 and the gas collecting hood 7 are located near the middle of the exhaust pipe 5, and a fan blade 8 located below the gas collecting hood 7 is installed below the fixing frame 4. The fan blade 8 is arranged on the side of the bottom of the fixing frame 4 away from the baffle 6, and the side of the fan blade 8 away from the baffle 6 is inclined upward;

[0026] There is no universal version of the fixing frame 4 tailored to the exhaust gas pipe 5. Considering the size of the exhaust gas pipe 5, for the sake of safety, the detection probe 2 and the gas collecting cover 7 installed thereon cannot be too far to the right. If it is tailored to the exhaust gas pipe 5, the detection probe 2, the gas collecting cover 7 and the fan blade 8 are all installed on the right side of the fixing frame 4 and on the central axis of the exhaust gas pipe 5;

[0027] The rotating shaft 801 of the fan blade 8 is rotatably connected to the permanent magnetic low-resistance bearing connecting seat 14 at the bottom of the fixed frame 4. The fan blade 8 adopts a non-powered fan. The permanent magnetic low-resistance bearing connecting seat 14 has small resistance. When the exhaust gas is discharged, the fan blade 8 can be driven to rotate by the exhaust gas. The rotation of the fan blade 8 has the effect of mixing the exhaust gas, so that the components in the exhaust gas are mixed relatively evenly. When used in conjunction with the gas collecting hood 7, the exhaust gas is continuously gathered from all sides to the bottom of the detection probe 2.

[0028] Working principle: After being treated, industrial waste gas is discharged through the waste gas pipe 5. When the waste gas circulates, it drives the fan blades 8 to rotate. The fan blades 8 have the effect of mixing the waste gas, so that the components in the waste gas are mixed relatively evenly. The waste gas flows upward and is continuously collected to the bottom of the detection probe 2 by multiple gas collecting hoods 7 with small upper and large lower parts. When passing through the detection probe 2, the harmful components in the waste gas are more easily captured by the detection probe 2, so that the detection result of the detector 1 is more accurate.
