Description

Technical Field

[0001] The utility model relates to the field of chemical product production, in particular to a chlorine gas exhaust sampling port absorption device for quality inspection. Background Art

[0002] During quality inspection, sampling and analyzing samples containing chlorine is a common operation. However, this process often produces excess chlorine that needs to be discharged. Chlorine is a toxic and hazardous gas. If discharged directly into the environment, it will not only cause serious pollution to the surrounding environment, but also pose a potential threat to the health of operators. Long-term exposure may even lead to serious health problems.

[0003] To address this technical challenge, a device capable of effectively treating excess chlorine is urgently needed. Through in-depth research and practical application, we have discovered that using alkali solution to absorb chlorine is an effective method. Alkali solution reacts chemically with chlorine, converting it into harmless or less harmful substances, thus preventing environmental pollution. However, in practice, directly discharging chlorine into an alkali solution absorption bottle can result in poor treatment results due to factors such as the chlorine flow rate and concentration. Utility Model Content

[0004] The purpose of the utility model is to provide a chlorine gas exhaust sampling port absorption device for quality inspection, so as to solve the technical problem that traditional chlorine gas absorption devices are prone to poor treatment effects due to factors such as the flow rate and concentration of chlorine gas.

[0006] A U-shaped tube, wherein both ends of the U-shaped tube are provided with sealing plugs for sealing, a chlorine gas inlet pipe is provided on the sealing plug on one side of the U-shaped tube, one end of the chlorine gas inlet pipe is connected to the interior of the U-shaped tube, and the other end of the chlorine gas inlet pipe is connected to the external discharge port of the sampling tube;

[0007] An alkali liquid absorption bottle is provided, wherein the alkali liquid absorption bottle is filled with alkaline liquid, and a sealing plug is also provided at the bottle mouth of the alkali liquid absorption bottle; a conduit is provided on the other side of the U-shaped tube, and the other end of the conduit passes through the sealing plug on the alkali liquid absorption bottle and extends into the alkaline liquid in the alkali liquid absorption bottle; the sealing plug on the alkali liquid absorption bottle is provided with an exhaust pipe connected to the outside.

[0008] In one embodiment, an exhaust pipe is further included, which is arranged on the sealing plug where the chlorine gas input pipe is located. One end of the exhaust pipe is connected to the air pump, and the other end of the exhaust pipe is connected to the inside of the U-shaped tube; a first valve is provided on the chlorine gas input pipe, and a second valve is provided on the exhaust pipe.

[0023] See also Figure 1The embodiment of the present application provides a chlorine gas sampling port absorption device for quality inspection, comprising a U-shaped tube 1 and an alkaline solution absorption bottle 2. A sealing plug 11 is provided at both ends of the U-shaped tube 1. A chlorine gas inlet pipe 12 is provided on the sealing plug 11 on one side of the U-shaped tube 1. One end of the chlorine gas inlet pipe 12 is connected to the interior of the U-shaped tube 1, and the other end of the chlorine gas inlet pipe 12 is connected to the discharge port of the sampling tube 6. The alkaline solution absorption bottle 2 contains alkaline liquid 21, and the bottle mouth of the alkaline solution absorption bottle 2 is also provided with a sealing plug 11. A conduit 3 is provided on the other side of the U-shaped tube 1. The other end of the conduit 3 passes through the sealing plug 11 on the alkaline solution absorption bottle 2 and extends into the alkaline liquid 21 inside the alkaline solution absorption bottle 2. The sealing plug 11 on the alkaline solution absorption bottle 2 is provided with an exhaust pipe 4 that is connected to the outside.

[0024] Excess chlorine in sampling tube 6 is transported from chlorine inlet pipe 12 into U-shaped tube 1. The chlorine then flows along U-shaped tube 1 to the other side and enters alkali solution absorption bottle 2 via conduit 3. Alkaline liquid 21 (specifically, sodium hydroxide solution with a mass fraction of 20%) in alkali solution absorption bottle 2 chemically reacts with the chlorine, removing the chlorine. After chlorine removal, the gas is discharged from exhaust pipe 4. Due to the large volume of U-shaped tube 1, the chlorine acts as a buffer and disperser after entering the tube, controlling the chlorine's flow rate and ensuring a more uniform and stable flow as it enters alkali solution absorption bottle 2.

[0025] In one embodiment, an emptying pipe 5 is further included. The emptying pipe 5 is arranged on the sealing plug 11 where the chlorine gas inlet pipe 12 is located. One end of the emptying pipe 5 is connected to the air pump, and the other end of the emptying pipe 5 is connected to the inside of the U-shaped tube 1; a first valve 7 is provided on the chlorine gas inlet pipe 12, and a second valve 8 is provided on the emptying pipe 5.

[0026] When it is necessary to replace the alkaline liquid 21 in the alkali liquid absorption bottle 2, first close the first valve 7 to prevent the chlorine in the sampling tube 6 from entering the U-shaped tube 1, and then open the second valve 8 (start the air pump at the same time). The air pump will work to pass the air through the emptying pipe 5 into the U-shaped tube 1, and then all the residual chlorine in the U-shaped tube 1 and the conduit 3 can be discharged into the alkali liquid absorption bottle 2 for treatment. After the emptying pipe 5 has been passed into the U-shaped tube 1 for a certain period of time (specifically 30 seconds to 1 minute), after the residual chlorine in the U-shaped tube 1 and the conduit 3 is completely discharged, close the second valve 8 (and turn off the air pump), remove the sealing plug 11 at the bottle mouth of the alkali liquid absorption bottle 2, and then the alkaline liquid 21 in the alkali liquid absorption bottle 2 can be replaced. After the replacement is completed, the sealing plug 11 is reinstalled on the alkali liquid absorption bottle 2, and the first valve 7 can be opened to continue to treat the chlorine in the sampling tube 6. By providing the drain pipe 5 , chlorine gas will not leak out when the alkaline liquid 21 in the alkaline liquid absorption bottle 2 is replaced, thereby preventing chlorine gas from polluting the environment.

[0027] In one embodiment, the sealing plug 11 is a glass sealing plug 11. Compared to a rubber sealing plug 11, the glass sealing plug 11 is more resistant to chlorine oxidative corrosion. In addition, a frosted structure can be provided at the outlet of the alkali solution absorption bottle 2 and the U-shaped tube 1 to improve the sealing between the sealing plug 11 and the bottle mouth.

[0028] In addition, the conduit 3, the chlorine gas inlet pipe 12 and the exhaust pipe 4 can all be glass tubes to avoid being corroded by chlorine gas.

[0029] In one embodiment, a one-way valve 9 is provided on the conduit 3 to prevent back suction. By providing the one-way valve 9, the alkaline liquid 21 in the alkali solution absorption bottle 2 is prevented from being sucked back into the U-shaped tube 1.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
