In this embodiment, the acid gas recovery bottles 502 are four, namely, a first recovery bottle, a second recovery bottle, a third recovery bottle and a fourth recovery bottle, the first recovery bottle and the second recovery bottle are respectively in NAOH solution, the third recovery bottle and the fourth recovery bottle are respectively in aqueous solution, the air duct 503 is sequentially connected with the first recovery bottle, the second recovery bottle, the third recovery bottle and the fourth recovery bottle, the acid gas is gradually absorbed, and the fourth recovery bottle is connected with the vacuum pump 501.
In this embodiment, in the high-pressure digestion process, the automatic parameters on the plc1402 are set, then the cover 202 on the protective cover 2 is opened, at this time, the cover 601 of the default digestion reaction tank 6 is in an open state, acid is automatically added into the digestion reaction tank 6 in which the digested object is placed by the manipulator device 4 to fix the volume, then the cover 202 of the protective cover 2 is covered, if the digestion reaction is severe, the pre-digestion is needed, the digestion reaction tank 6 cannot be covered in the pre-digestion process, the high-pressure digestion is performed after the pre-digestion is finished, at this time, the cover 601 is needed to be covered by the manipulator device 4, after the high-pressure digestion is finished, the cover 601 is opened by the manipulator device 4, acid is needed to be removed by heating by the heating plate 104, and after the acid removal is finished, the manipulator device 4 is added with water to fix the volume, so that the digestion is completed. During the pre-digestion and acid-expelling process, a large amount of acid gas can be dissipated from the digestion reaction tank 6, when the high-pressure digestion is carried out, although the opening of the digestion reaction tank 6 is airtight, a small amount of acid can leak to the outside from the pressure release small hole because of too high pressure, so that during the pre-digestion process, the acid gas absorbing device 5 is connected to the upper part of the sealing cover 3 through the air duct 503, the dissipated acid gas is absorbed, and the plurality of third through holes 2022 are arranged to enable the acid gas to be discharged from the inner cavity of the supporting plate 203 quickly and effectively, so that the gas efficiency is improved.
The above-mentioned embodiments are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and all the modifications of equivalent structures made by the description and drawings of the present invention or direct/indirect application in other related technical fields are included in the scope of the present invention under the inventive concept of the present invention.
