The device comprises a first absorption tank, a second absorption tank and a water pumping mechanism, a spraying water outlet mechanism is arranged in the first absorption tank, a hollow shaft is rotatably connected to the bottom of the first absorption tank, and an exhaust pipe is arranged at the top; a driving mechanism is arranged at the lower end of the hollow shaft, the upper end extends into the first absorption tank and is connected with a rotating rod, a tail gas exhaust mechanism is arranged on the hollow shaft, and the upper end of the rotating rod is connected with an exhaust mechanism; the bottom of the second absorption tank is rotationally connected with a lower hollow rod, the lower hollow rod and the hollow shaft are in transmission through a transmission mechanism, the upper end of the lower hollow rod extends into the second absorption tank and is fixedly provided with an upper hollow rod, the outer wall of the upper hollow rod is provided with an air outlet mechanism, and the upper end of the upper hollow rod is rotationally connected with the tail end of the exhaust pipe; a pollution discharge mechanism is arranged on the outer wall of the lower hollow rod; and the water pumping mechanism is respectively connected with the spraying water outlet mechanism and the second absorption tank. The device can fully absorb the hydrogen chloride tail gas.

Description

technical field [0001] The invention relates to a high-efficiency hydrogen chloride tail gas absorption device, which belongs to the technical field of tail gas treatment. Background technique [0002] Hydrogen chloride, a corrosive non-combustible gas, does not react with water but is easily soluble in water, and often exists in the form of hydrochloric acid fumes in the air. Soluble in ethanol and ether, also soluble in many other organic substances; soluble in water, at 25°C and 1 atmospheric pressure, 1 volume of water can dissolve 503 volumes of hydrogen chloride gas. [0003] With the rapid development of my country's chlor-alkali, polyvinyl chloride and other industries, the purification of hydrogen chloride tail gas in the production process has attracted more and more attention. However, most of the hydrogen chloride tail gas treatment equipment that has been used at present still adopts the foam tower absorption process, which has the disadvantages of low hydrogen...
