Abstract

The invention discloses a device for purifying a WSA acid-making raw material acid gas. When the device is used, the acid gas in an acid gas pipeline behind a vacuum carbonate desulphurization vacuumpump enters a purifying segment of a purifying container through an acid gas inlet, is purified and washed by a purifying solution, entering from a purifying solution inlet, sprayed by a nozzle, and is washed by a filter screen to remove oils, naphthalene and a desulphurization solution entrained by the acid gas, and the washed acid gas goes upwards through a gas communicating pipeline, enters a separation segment from the purifying section, undergoes gas-liquid separation, and enters a burner of a WSA acid maker through an acid gas outlet. A purifying solution discharged from the purifying segment flows out from a purifying solution outlet and enters a discharging container, and a separation liquid obtained after the gas-liquid separation in the separation segment enters the discharging container through a separation liquid outlet, so the continuous discharge of the purifying solution and the separation liquid is achieved, acid gas leakage is avoided, the purification of the WSA acid-making raw material acid gas is achieved, the blockage frequency of the acid gas pipeline is reduced, the running period of an acid making system is prolonged, and the operating rate of the acid making system is improved.

Description

technical field [0001] The invention relates to the technical fields of vacuum carbonate desulfurization and WSA acid production, in particular to a purification device for raw material acid gas of WSA acid production. Background technique [0002] WSA acid production is a wet acid production technology developed by Topsoe Company in Denmark. Because of its advantages of no need for dehydration before conversion, low acid mist content in tail gas and no waste liquid discharge during the process, it has been adopted by domestic coking enterprises in recent years. It is widely used and matched with the vacuum carbonate desulfurization process. [0003] Among them, the acid gas containing H2S after the vacuum pump of the desulfurization regeneration unit needs to enter the main burner of the WSA acid incinerator. Because the sour gas contains oil, naphthalene and impurities in the desulfurization liquid, during the transportation of the sour gas, the potassium salt in the desu...
