Description

Technical Field

[0001] The utility model relates to the field of water purifier workshops, in particular to a tail gas treatment device. Background Art

[0002] Hydrogen chloride is a type of halogenated hydride, a colorless gas with a pungent odor. Hydrogen chloride is highly soluble in water. At 0°C, 1 volume of water can dissolve approximately 500 volumes of hydrogen chloride. Its aqueous solution is usually called hydrochloric acid. Hydrogen chloride and its aqueous solution are widely used in scientific research and industrial production. When treating hydrogen chloride tail gas, a tail gas treatment device is required.

[0003] When the hydrogen chloride tail gas is treated by water, bubbles are easily generated in the water when the hydrogen chloride tail gas enters the water, which can easily cause the hydrogen chloride to be in the bubbles. This can easily lead to incomplete treatment of the hydrogen chloride tail gas, causing the device to discharge incompletely treated hydrogen chloride. Utility Model Content

After the motor 5 is started, the motor 5 can drive the stirring frame 52 to rotate, so that the effect of the device in treating the hydrogen chloride tail gas is better.

[0028] An air inlet pipe 6 is fixed at the bottom of the first treatment tank 2 , and a first pump 61 is installed in the middle of the air inlet pipe 6 ; by connecting the hydrogen chloride tail gas output device to the input end of the air inlet pipe 6 and then starting the first pump 61 , the hydrogen chloride tail gas can be pumped into the first treatment tank 2 .

[0029] A connecting pipe 7 is fixed at one end of the first treatment tank 2, a second pump 71 is installed in the middle of the connecting pipe 7, and the output end of the connecting pipe 7 extends from the bottom of the second treatment tank 3 into the second treatment tank 3; the first treatment tank 2 and the second treatment tank 3 are connected through the connecting pipe 7, and when the second pump 71 is started, the hydrogen chloride gas treated once in the first treatment tank 2 can be pumped into the second treatment tank 3.

[0030] The discharge mechanism includes an extraction pipe 8, which is fixed to one end of the second treatment tank 3. A third pump 81 is installed at the upper end of the extraction pipe 8. A discharge pipe 82 is fixed in the middle of the extraction pipe 8. A return pipe 83 is fixed at the lower end of the extraction pipe 8. The output end of the return pipe 83 extends from the bottom of the first treatment tank 2 into the first treatment tank 2. A valve 84 is installed in the middle of the discharge pipe 82 and the return pipe 83. When the device is in operation, the hydrogen chloride tail gas is first treated once through the first treatment tank 2, and then the hydrogen chloride gas that has been treated once is treated twice through the second treatment tank 3. Before this, the valve 84 on the return pipe 83 is closed. Close and open the valve 84 on the discharge pipe 82, then start the third pump 81 to discharge a small amount of the secondarily treated gas from the discharge pipe 82. After the inspector has inspected the small amount of extracted gas, if the gas can be discharged or recovered, start the third pump 81 again to discharge the treated gas from the discharge pipe 82. If the gas does not meet the discharge or recovery standards, close the valve 84 on the discharge pipe 82 and open the valve 84 on the reflux pipe 83.

After the preparation is completed, the first pump 61 is started to allow the hydrogen chloride tail gas to be pumped into the first treatment tank 2, so that the water in the first treatment tank 2 performs the first treatment on the hydrogen chloride gas. Then the second pump 71 is started, and the first treatment tank 2 and the second treatment tank 3 are connected through the connecting pipe 7. When the second pump 71 is started, the hydrogen chloride gas that has been treated once in the first treatment tank 2 can be pumped into the second treatment tank 3, so that the water in the second treatment tank 3 performs the second treatment on the hydrogen chloride gas. The gas is treated for the second time. At this time, the valve 84 on the discharge pipe 82 is opened, and the third pump 81 is briefly started, so that the inspector can collect and test the treated gas through the output end of the discharge pipe 82. After the inspector has tested a small amount of extracted gas, if the gas can be discharged or recovered, the third pump 81 is started again to discharge the treated gas from the discharge pipe 82. If the gas does not meet the discharge or recovery standards, the valve 84 on the discharge pipe 82 is closed and the valve 84 on the reflux pipe 83 is opened. In this way, when the third pump 81 is started again, the gas can be pumped back into the first treatment tank 2 again, so that the device can process the gas again to ensure that the gas is completely treated.
