Device and method for absorbing carbon disulfide in hydrogen sulfide gas by using solvent

The invention discloses a device and a method for absorbing carbon disulfide in hydrogen sulfide gas by using solvent, which belong to the technical field of hydrogen sulfide gas and carbon disulfide preparation. The device of the invention mainly comprises an absorption tower, an analytical tower, a gas-liquid separator, a heat exchanger, a cooler, a heater, a pump, a valve and the like; and the method is to produce H2S and CS2 products by using the device and absorption and separation in a transfer mass dynamic control process and solvent. The device of the invention has a simple structure and low cost; and the method of the invention has the advantages of good absorption/separation effect, full utilization of resources, reduced energy consumption, low production cost and convenient popularization and application, wherein the absorption rate of CS2 is up to 99 percent. The device and the method of the invention can be widely applied to separation of H2S gases and CS2 in industrial production, particularly the separation of CS2 from H2S gases in the process of preparing CS2 by using natural gases.
