Description

Technical Field

[0001] This application relates to an exhaust gas absorption device, and particularly to an exhaust gas absorption device for coal analysis. Background Art

[0002] In coal combustion analysis, when measuring the calorific value of coal, due to reasons of the equipment itself or the laboratory area, after the test is completed, the equipment has no automatic exhaust gas function, resulting in the exhaust gas being unable to be discharged outdoors. Only after the bomb calorimeter is taken out by the laboratory technician, can the exhaust gas be manually discharged. In this way, a large amount of exhaust gas will be generated because gases such as sulfur dioxide and nitrogen oxides produced by the coal sample during the test cannot be discharged outdoors. Especially in the case of a large amount of high-sulfur coal in this factory, when ten calorimeters in the team are used simultaneously, a large amount of pungent odor is discharged, seriously affecting the health of the laboratory technicians.

[0050] The reflux assembly 140 is arranged on one side of the outer shell 110.

[0051] In this embodiment, a part of the exhaust assembly 130 is arranged inside the outer shell 110, and the other part is arranged on the cover body 120. After injecting the solution into the outer shell 110, the cover body 120 is connected to the outer shell 110. After the connection, the exhaust assembly 130 is connected. After the connection is completed, the reflux assembly 140 is connected to the cover body 120. Gas A is introduced into the exhaust assembly 130, so that gas A is repeatedly mixed with the solution through the exhaust assembly 130 to generate water, and the water is prevented from overflowing through the reflux assembly 140;

[0052] Further, gas A is the waste gas (mostly sulfur dioxide gas) generated by coal combustion during the determination of the calorific value of coal in coal analysis;

[0053] The solution in the outer shell 110 is sodium hydroxide solution. A large amount of sulfur dioxide discharged is absorbed by using sodium hydroxide solution. At the same time, phenolphthalein indicator is added to the solution. When the red color fades or disappears, the sodium hydroxide solution is replaced (the reaction formula is SO2 + 2OH - = SO3 2- + H2O);

[0054] By arranging a solution in the outer shell 110 and passing the waste gas into the solution through the exhaust assembly 130, since a part of the exhaust assembly 130 is arranged at the bottom of the outer shell 110, the waste gas moves upward from the bottom of the solution, and reacts fully with the solution during the movement, ensuring the reaction effect. At the same time, the waste gas absorption device 100 is easy to manufacture, is beneficial to the removal of waste gas in the laboratory, is beneficial to the physical and mental health of personnel, and can meet the needs of different laboratories.

[0055] Such as Figures 1 - 3 shown, in one embodiment,

[0056] The exhaust assembly 130 includes:

[0057] The intake pipe 131, the intake end of the intake pipe 131 is located outside the cover body 120, and the outlet end of the intake pipe 131 penetrates through the cover body 120 and extends into the outer shell 110;

[0058] The outlet pipe 132 is detachably connected to the outlet end of the intake pipe 131, the outlet pipe 132 is located at the bottom of the outer shell 110, and there are several outlet holes 133 on the outlet pipe 132.

[0059] In this embodiment, the intake pipe 131 is arranged at the center of the cover body 120. During the installation process, the outlet pipe 132 is pre-installed at the bottom of the outer shell 110, and a solution is added into the outer shell 110 to submerge the outlet pipe 132 in the solution. After the installation is completed, the cover body 120 is installed on the outer shell 110. After the installation is completed, the intake pipe 131 and the outlet pipe 132 are installed.
