Description

Technical Field

[0001] The utility model relates to the technical field of industrial waste gas collection, in particular to a sampler for industrial waste gas detection. Background Art

[0002] A large amount of waste gas is emitted during industrial production, which contains a large amount of sulfides, nitrides, water vapor and smoke particles. There are corresponding removal devices for sulfides and nitrides. After chemical reactions, water vapor and particulate matter remain. The emission of waste gas needs to comply with relevant environmental protection standards. The waste gas will be sampled and tested and analyzed before emission.

[0003] When existing samplers extract industrial waste gas, they will also draw external air into the sampler, which can easily affect the industrial waste gas detection results. At the same time, it is inconvenient to take multiple samples during sampling, which affects the accuracy of industrial waste gas detection.

[0004] Therefore, there is an urgent need for a sampler for industrial waste gas detection to solve the problem of inaccurate sampling by the sampler. Utility Model Content

The connecting plate is welded to the inner side of the second connecting tube. The pin is installed in the middle position of the bottom of the connecting plate.

[0009] The negative pressure generated inside the negative pressure bottle draws the industrial waste gas into the negative pressure bottle, which is convenient for the sampling of industrial waste gas. The sampling mechanism can collect the industrial waste gas tightly, so that the external air will not be mixed into the industrial waste gas, thereby improving the sampling purity of the industrial waste gas and further improving the accuracy of industrial waste gas detection.

[0010] Preferably, the interior of the connecting plate is a hollow structure, and tinfoil is installed inside the mouth of the negative pressure bottle.

[0011] The internal pressure of the negative pressure bottle is lower than the atmospheric pressure. The tin foil is used to seal the negative pressure bottle. The industrial waste gas enters the negative pressure bottle from connecting pipe 1, connecting plate, connecting pipe 2, and pin in sequence.

[0012] Preferably, a valve is installed in the middle of the second connecting pipe, and a protective frame is fixedly connected to the bottom of the connecting plate by screws, and the protective frame is located outside the negative pressure bottle.

[0013] Preferably, the three groups of protective frames are distributed in a circular pattern at the bottom of the connecting plate.

[0014] Preferably, the fixing mechanism includes a second fixing ring, bolts, a sealing ring and an anti-slip pad. The second fixing ring is fixedly connected to the top of the first fixing ring by bolts. The sealing ring is pressed against the inner side of the bottom notch of the first fixing ring. Several groups of the anti-slip pads are bonded to the inner sides of the first fixing ring and the second fixing ring.

[0015] Preferably, several groups of the anti-slip pads are symmetrically distributed inside the first fixing ring and the second fixing ring.

[0016] Compared with the prior art, this application has at least the following beneficial effects:

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] See also Figure 1-4 The present application discloses a sampler for industrial waste gas detection, comprising a fixing ring 1 and a connecting pipe 2. The connecting pipe 2 is connected to the bottom of the fixing ring 1. Industrial waste gas can enter the interior of the connecting pipe 2 from the notch at the bottom of the fixing ring 1. A sampling mechanism is provided at the bottom of the connecting pipe 2. Industrial waste gas enters the sampler from the connecting pipe 2. A fixing mechanism is provided at the top of the fixing ring 1. The fixing mechanism facilitates fixing the sampler to the industrial waste gas pipeline.

[0026] Specifically, the sampling mechanism includes a connecting disk 111, a connecting tube 112, a negative pressure bottle 113, a connecting piece 114 and a pin 115. The connecting tube 112, the connecting disk 111 and the connecting tube 112 are connected in sequence. The interior of the connecting disk 111 is a hollow structure. The negative pressure bottle 113 is threadedly connected to the bottom of the connecting tube 112. Tin foil is installed inside the bottle mouth of the negative pressure bottle 113. The connecting piece 114 is welded to the inside of the connecting tube 112. The pin 115 is installed in the middle position of the bottom of the connecting piece 114. A valve 116 is installed in the middle position of the connecting tube 112. The bottom of the connecting disk 111 is fixed with a protective frame 117 by screws. The protective frame 117 is located on the outside of the negative pressure bottle 113. Three groups of protective frames 117 are located at the bottom of the connecting disk 111 and are distributed in a circle.

[0027] Among them, when the fixing ring 1 is fixed to the industrial waste gas pipeline, the staff rotates the negative pressure bottle 113 to the connecting pipe 2 112, and the pin 115 punctures the tin foil at the bottle mouth of the negative pressure bottle 113, allowing the industrial waste gas to enter the negative pressure bottle 113. The staff opens the valve 116, and the industrial waste gas enters the connecting plate 111 from the connecting pipe 2. The negative pressure generated inside the negative pressure bottle 113 draws the industrial waste gas from the connecting plate 111 into the negative pressure bottle 113, which is convenient for the industrial waste gas to enter the negative pressure bottle 113. Sampling, through the close collection of industrial waste gas by the sampling mechanism, external air will not be mixed into the industrial waste gas, thereby improving the sampling purity of industrial waste gas, and then improving the accuracy of industrial waste gas detection, making the sampler easy to use; after the negative pressure bottle 113 is collected, the staff will remove the negative pressure bottle 113, and the staff will use the cover to seal the negative pressure bottle 113; the protective frame 117 protects the negative pressure bottle 113 to prevent the negative pressure bottle 113 from falling, thereby protecting the safety of the negative pressure bottle 113.

[0028] Specifically, the fixing mechanism includes a fixing ring 211, a bolt 212, a sealing ring 213 and an anti-slip pad 214. The fixing ring 211 is fixedly connected to the top of the fixing ring 1 by the bolt 212. The sealing ring 213 is pressed against the inner side of the bottom notch of the fixing ring 1. Several groups of anti-slip pads 214 are bonded to the inner sides of the fixing ring 1 and the fixing ring 2 211. Several groups of anti-slip pads 214 are symmetrically distributed on the inner sides of the fixing ring 1 and the fixing ring 2 211.

[0029] When the sampler is in use, the staff fixes the sampler to the exhaust gas pipe through the fixing ring 1 and the fixing ring 211. The sealing ring 213 seals the exhaust gas pipe and the fixing ring 1 to prevent exhaust gas leakage. At the same time, the anti-slip pad 214 is installed between the fixing ring 1 and the fixing ring 211 and the exhaust gas pipe to facilitate the fixation of the sampler, the multiple collection of exhaust gas by the sampler, and the multiple use of the sampler.

[0030] When in use, the negative pressure generated inside the negative pressure bottle 113 draws the industrial waste gas into the negative pressure bottle 113, which facilitates the sampling of industrial waste gas. The sampling mechanism collects the industrial waste gas tightly, so that the external air will not be mixed into the industrial waste gas, thereby improving the sampling purity of the industrial waste gas and further improving the accuracy of industrial waste gas detection.

[0031] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
