The utility model relates to a corrosive gas absorption
system. The corrosive gas absorption
system comprises an absorption tank, a
heat exchanger, a
peristaltic pump and a
diaphragm pump, a gas inlet
pipe and a liquid inlet
pipe are arranged on the absorption tank, a
nozzle is arranged at the end of the liquid inlet
pipe, the lower end of the gas inlet pipe is located on the lower side of the liquid inlet pipe, the upper end of the gas inlet pipe is connected with a first connecting pipe, and the
peristaltic pump is arranged on the first connecting pipe; the
diaphragm pump is used for pumping corrosive gas into the absorption tank, a
cooling coil is arranged in the absorption tank, a cooling liquid inlet pipe and a cooling liquid outlet pipe are arranged on the absorption tank, the bottom of the absorption tank is communicated with an inlet of the
cooling coil through a second connecting pipe, and a liquid inlet of the
diaphragm pump is communicated with an outlet of the
cooling coil through a third connecting pipe; and a liquid outlet of the diaphragm pump is communicated with the liquid inlet pipe through a fourth connecting pipe. The pressure of the corrosive gas is increased after the corrosive gas flows through the
peristaltic pump, so that the gas in the gas storage bag can be completely conveyed into the absorption tank, and the pressure during gas absorption can be increased. The corrosive gas enters the absorption tank after passing through the one-way valve after being pressurized, and the
tail end section of the gas outlet is provided with the filter cloth, so that absorption liquid is effectively prevented from entering a
gas pipeline. The absorption liquid is sprayed into the absorption tank, and tiny liquid drops generated by spraying are beneficial to rapid absorption of corrosive gas. After heat generated in the absorption process is cooled through the
heat exchanger,
high absorption driving force is maintained, and efficient absorption is facilitated.
