[0035] Working principle;

[0036] A mixed gas containing hydrogen and hydrochloric acid is first introduced into the filter chamber 601 of the filter block 200 through the inlet pipe 209. In the filter chamber 601, the filter layers 604 filling both sides of the filter plate 603 first intercept and adsorb impurities such as solid particles in the gas. The filtered gas enters the first spiral tube 205 through the first conduit 206, and then enters the bottom of the separation tower 101 through the second conduit 207 connected to it. With the help of the aeration plate 208 connected to the end of the second conduit 207, the gas can be evenly dispersed in the separation tower 101, increasing the contact area with subsequent substances, so that the solution can fully react with the hydrochloric acid in the mixed gas.

[0037] Meanwhile, the storage tank 302 stores the reaction solution used for auxiliary separation. Under the action of the pumping component, the delivery pump 301 is started under the control of the DSP controller 502, which draws the solution in the storage tank 302 into the connecting pipe 304 and then delivers it upward through the delivery pipe 300. After passing through the second spiral tube 406, the delivery pipe 300 delivers the solution to the upper surface of the separation tower 101 for spraying. The hydrochloric acid in the upward moving mixed gas undergoes further reaction. The solution is in full contact with the mixed gas in the separation tower 101. Utilizing the strong absorption property of calcium chloride for hydrochloric acid, the hydrochloric acid in the mixed gas is absorbed by the solution, realizing the separation of hydrochloric acid. The solution containing hydrochloric acid flows into the storage tank 302 through the liquid inlet pipe 303. At the same time, the hydrogen in the mixed gas cannot react with calcium chloride, so it moves upward along the separation tower 101 and is discharged from the top of the separation tower 101 through the gas outlet pipe 102. Thus, the separation of hydrogen and hydrochloric acid is realized, and it is also convenient for the staff to collect the separated hydrogen.

[0038] The electric heating rod 500, which is inserted into the bottom of one side of the storage tank 302, starts to work and heats the solution in the storage tank 302. As the temperature rises, the hydrochloric acid in the solution vaporizes and evaporates. The vaporized hydrochloric acid enters the second spiral tube 406 through the infusion tube 400. During the flow, it exchanges heat with the external environment and gradually cools down. Then it enters the collection tank 404 through the connecting tube 405.

[0039] In addition, the blower 202 operates under the control of the DSP controller 502. The output airflow passes through the first ventilation pipe 203. Part of the airflow enters the guide pipe 201 located on the outer surface of the first spiral tube 205 and connects to its inner cavity to improve the heat dissipation speed of the mixed gas entering the first spiral tube 205. The other part of the airflow enters the inner cavity of the guide pipe 201 located on the outer surface of the second spiral tube 406 through the second ventilation pipe 204 connected to the top of the first ventilation pipe 203, which helps the heat exchange effect of the vaporized hydrochloric acid in the second spiral tube 406 and accelerates the condensation speed of the vaporized hydrochloric acid.
